Strong support to provide DAA therapy to all patients with HCV
, a large, real-world analysis finds.
Improved outcomes were seen among patients without cirrhosis, those with compensated cirrhosis, and those with existing liver decompensation, the authors noted.
The findings highlight a “substantial need to provide DAA therapy to all patients with HCV, regardless of disease stage or financial status,” wrote Mindie Nguyen, MD, of Stanford University Medical Center, Palo Alto, Calif., and coinvestigators.
“Additional national efforts are needed to reach and treat U.S. population groups that are underinsured or not insured, incarcerated and otherwise marginalized, such as users of illicit drugs, who are also at higher risk of disease complication and reinfection,” they said.
The study was published online in JAMA Internal Medicine.
CHC and its complications are associated with high rates of illness and death. However, large-scale data on long-term liver and nonliver effects of DAA treatment are limited.
For their study, Dr. Nguyen and colleagues analyzed administrative claims data from 2010 to 2021 for 245,596 adults with CHC, of whom 40,654 had received one or more DAA therapies (without interferon) and 204,942 had not received treatment.
DAA-treated patients were slightly older than their untreated peers (mean age, 59.9 years, vs. 58.5 years) and were more likely to be male (62% vs. 58%) and White (59% vs. 57%), and to have diabetes (26% vs. 25%) and cirrhosis (44% vs. 29%).
For liver outcomes, DAA therapy was associated with a lower incidence of decompensation (28.2 vs. 40.8 per 1,000 person-years; P < .001) and hepatocellular carcinoma (HCC) in compensated cirrhosis (20.1 vs. 41.8; P < .001).
For nonliver outcomes, DAA treatment was associated with a lower incidence of diabetes (30.2 vs. 37.2 per 1,000 person-years; P < .001) and chronic kidney disease (31.1 vs. 34.1; P < .001).
The all-cause mortality rate per 1,000 person-years was 36.5 in the DAA-treated group, vs. 64.7 in the untreated group (P < .001).
In multivariable regression analysis, DAA treatment was independently associated with a significant decrease in the risk for HCC (adjusted hazard ratio [aHR], 0.73), decompensation (aHR, 0.36), diabetes (aHR, 0.74), chronic kidney disease (aHR, 0.81), cardiovascular disease (aHR, 0.90), nonliver cancer (aHR, 0.89), and mortality (aHR, 0.43).
The 57% lower mortality rate observed among DAA-treated vs. untreated patients aligns with a large French study of adults with CHC.
“Because HCV treatment with a DAA regimen is well tolerated for nearly all patients, we believe these findings provide further support for universal HCV treatment coverage for all patients affected by HCV,” Dr. Nguyen and colleagues wrote.
The strengths of this study are its large sample of DAA-treated and untreated patients from diverse racial and ethnic groups from across the United States and from diverse practice settings (not just tertiary centers).
One limitation is that the study cohort included only patients covered by private insurance; therefore, the findings may not be generalizable to individuals who are underinsured or not insured. Miscoding and misclassification are also possible with large claims databases.
Support for the study was provided by Stanford University and the Stanford Center for Population Health Sciences. Dr. Nguyen has received institutional grants and advisory board fees from Gilead Sciences outside the submitted work.

Nonheavy alcohol use associated with liver fibrosis, NASH
according to a new report.
An analysis of current drinkers in the Framingham Heart Study found that a higher number of drinks per week and higher frequency of drinking were associated with increased odds of fibrosis among patients whose consumption fell below the threshold for heavy alcohol use.
“Although the detrimental effects of heavy alcohol use are well accepted, there is no consensus guideline on how to counsel patients about how nonheavy alcohol use may affect liver health,” Brooke Rice, MD, an internal medicine resident at Boston University, said in an interview.
“Current terminology classifies fatty liver disease as either alcoholic or nonalcoholic,” she said. “Our results call this strict categorization into question, suggesting that even nonheavy alcohol use should be considered as a factor contributing to more advanced nonalcoholic fatty liver disease [NAFLD] phenotypes.”
The study was published online in Clinical Gastroenterology and Hepatology.
Analyzing associations
NAFLD and alcohol-related liver disease, which are the most common causes of chronic liver disease worldwide, are histologically identical but distinguished by the presence of significant alcohol use, the study authors wrote.
Heavy alcohol use, based on guidelines from the American Association for the Study of Liver Diseases, is defined as more than 14 drinks per week for women or more than 21 drinks per week for men.
Although heavy alcohol use is consistently associated with cirrhosis and steatohepatitis, studies of nonheavy alcohol use have shown conflicting results, the authors wrote. However, evidence suggests that the pattern of alcohol consumption – particularly increased weekly drinking and binge drinking – may be an important predictor.
Dr. Rice and colleagues conducted a cross-sectional study of 2,629 current drinkers in the Framingham Heart Study who completed alcohol-use questionnaires and vibration-controlled transient elastography between April 2016 and April 2019. They analyzed the association between fibrosis and several alcohol-use measures, including total consumption and drinking patterns, among nonheavy alcohol users whose liver disease would be classified as “nonalcoholic” by current nomenclature.
The research team defined clinically significant fibrosis as a liver stiffness measurement of 8.2 kPa or higher. For at-risk NASH, the researchers used two FibroScan-AST (FAST) score thresholds – greater than 0.35 or 0.67 and higher. They also considered additional metabolic factors such as physical activity, body mass index, blood pressure, glucose measures, and metabolic syndrome.
Participants were asked to estimate the frequency of alcohol use (average number of drinking days per week during the past year) and the usual quantity of alcohol consumed (average number of drinks on a typical drinking day during the past year). Researchers multiplied the figures to estimate the average total number of drinks per week.
Among the 2,629 current drinkers (53% women, 47% men), the average age was 54 years, 7.2% had diabetes, and 26.9% met the criteria for metabolic syndrome. Participants drank about 3 days per week on average with a usual consumption of two drinks per drinking day, averaging a total weekly alcohol consumption of six drinks.
The average liver stiffness measurement was 5.6 kPa, and 8.2% had significant fibrosis.
At the FAST score threshold of 0.67 or greater, 1.9% of participants were likely to have at-risk NASH, with a higher prevalence in those with obesity (4.5%) or diabetes (9.5%). At the FAST score threshold of greater than 0.35, the prevalence of at-risk NASH was 12.4%, which was higher in those with obesity (26.3%) or diabetes (34.4%).
Overall, an increased total number of drinks per week and higher frequency of drinking days were associated with increased odds of fibrosis.
Almost 17.5% of participants engaged in risky weekly drinking, which was defined as 8 or more drinks per week for women and 15 or more drinks per week for men. Risky weekly drinking was also associated with higher odds of fibrosis.
After excluding 158 heavy drinkers, the prevalence of fibrosis was unchanged at 8%, and an increased total of drinks per week remained significantly associated with fibrosis.
In addition, multiple alcohol-use measures were positively associated with a FAST score greater than 0.35 and were similar after excluding heavy alcohol users. These measures include the number of drinks per week, the frequency of drinking days, and binge drinking.
“We showed that nonheavy alcohol use is associated with fibrosis and at-risk NASH, which are both predictors of long-term liver-related morbidity and mortality,” Dr. Rice said.
Implications for patient care
The findings have important implications for both NAFLD clinical trials and patient care, the study authors wrote. For instance, the U.S. Dietary Guidelines for Americans recommend limiting alcohol use to one drink per day for women and two drinks per day for men.
“Our results reinforce the importance of encouraging all patients to reduce alcohol intake as much as possible and to at least adhere to current U.S. Dietary Guidelines recommended limits,” Dr. Rice said. “Almost half of participants in our study consumed in excess of these limits, which strongly associated with at-risk NASH.”
Additional long-term studies are needed to determine the benefits of limiting alcohol consumption to reduce liver-related morbidity and mortality, the authors wrote.
The effect of alcohol consumption on liver health “has been controversial, since some studies have suggested that nonheavy alcohol use can even have some beneficial metabolic effects and has been associated with reduced risk of fatty liver disease, while other studies have found that nonheavy alcohol use is associated with increased risk for liver-related clinical outcomes,” Fredrik Åberg, MD, PhD, a hepatologist and liver transplant specialist at Helsinki University Hospital, said in an interview.
Dr. Åberg wasn’t involved with this study but has researched alcohol consumption and liver disease. Among non–heavy alcohol users, drinking more alcohol per week is associated with increased hospitalization for liver disease, hepatocellular carcinoma, and liver-related death, he and his colleagues have found.
“We concluded that the net effect of non-heavy drinking on the liver is harm,” he said. “Overall, this study by Rice and colleagues supports the recommendation that persons with mild liver disease should reduce their drinking, and persons with severe liver disease (cirrhosis and advanced fibrosis) should abstain from alcohol use.”
The study authors are supported in part by the National Institute of Diabetes and Digestive and Kidney Diseases, a Doris Duke Charitable Foundation Grant, a Gilead Sciences Research Scholars Award, the Boston University Department of Medicine Career Investment Award, and the Boston University Clinical Translational Science Institute. The Framingham Heart Study is supported in part by the National Heart, Lung, and Blood Institute. The authors and Dr. Åberg reported no relevant financial relationships.

Lifestyle guidance app may be effective in NASH
After 48 weeks, nonalcoholic fatty liver disease activity scores (NAS) improved in 13 out of 19 patients who used the NASH app developed by CureApp, according to Masaya Sato of the University of Tokyo and colleagues.
If confirmed by a controlled trial, these preliminary results could show promise for digital therapeutics, the researchers stated in an article published in The American Journal of Gastroenterology.
“The widespread use of smartphones, which can process and communicate data in real time, makes them an ideal platform for therapeutic interventions,” they said.
Although lifestyle changes can reduce NASH activity, many patients have difficulty keeping up these changes. Not enough counselors are available to guide patients in healthy practices, and hiring the counselors is expensive, the researchers wrote.
Smartphone applications aimed at instilling healthy behavior have been tried in diabetes, smoking, hypertension, alcoholism, and even cancer, they noted. They wanted to see whether something similar could be done with NASH.
The researchers recruited 19 patients with biopsy-confirmed NASH who consumed no more than moderate amounts of alcohol and had a body mass index (BMI) of at least 25 kg/m2. Their mean age was 52 years, mean BMI was 32, and mean NAS was 5.0.
The patients downloaded the NASH app onto their phones and entered their baseline profile information, including age, gender, diet and exercise practices, and social characteristics. On the basis of this information and daily weight measurements, the system proposed lifestyle improvement programs tailored to each individual. Its chatbot presented them in the form of behavioral goals and lectures from virtual nurses.
While patients used the app for 48 weeks, they also received standard outpatient care for NASH from live physicians, who also promoted the use of the app and provided additional education related to NASH.
The patients underwent liver biopsies within 90 days prior to beginning the study and at the end of 48 weeks. The researchers compared the changes in these patients versus those in a hypothetical control group, which they based on the placebo group in a previous study.
In the patients who used the app, the mean NAS change from baseline to week 48, the main endpoint, was –2.05 (95% confidence interval, –3.00 to –1.11). This result was statistically significant compared with the hypothetical control group, in which the mean change in NAS was –0.7 (P < .001).
In 11 of the patients, NAS decreased by at least 2 points without worsening of liver fibrosis. In eight patients, the researchers observed resolution of steatohepatitis, which they defined as disappearance of hepatocyte ballooning.
In 12 patients with stage F2 or F3 fibrosis, the average stage went from 2.5 to 2.0 (P = .02). No patient with stage F1 fibrosis showed a reduction in fibrosis stage. The scores for steatosis decreased in 11 patients, for lobular inflammation in 9 patients, and for ballooning in 10 patients.
The patients lost an average of 8.3% of their body weight, which was significant, compared with their baseline (P < .001). The patients also notched significant reductions in average serum levels of AST, ALT, gamma-glutamyltransferase, alkaline phosphatase, and triglycerides.
The researchers noted that the lack of a real control group and the small size of the study population limited the importance of their findings. A larger randomized, controlled trial is needed to confirm their results.
During the study, physicians browsed the patients’ data and provided them with feedback about it, the researchers wrote. But the study did not measure the amount of time the physicians spent on this activity.
CureApp founded the study, and one of the authors is a consultant for the company.

Although lifestyle changes can reduce NASH activity, many patients have difficulty keeping up these changes. Not enough counselors are available to guide patients in healthy practices, and hiring the counselors is expensive, the researchers wrote.
Smartphone applications aimed at instilling healthy behavior have been tried in diabetes, smoking, hypertension, alcoholism, and even cancer, they noted. They wanted to see whether something similar could be done with NASH.
The researchers recruited 19 patients with biopsy-confirmed NASH who consumed no more than moderate amounts of alcohol and had a body mass index (BMI) of at least 25 kg/m2. Their mean age was 52 years, mean BMI was 32, and mean NAS was 5.0.
The patients downloaded the NASH app onto their phones and entered their baseline profile information, including age, gender, diet and exercise practices, and social characteristics. On the basis of this information and daily weight measurements, the system proposed lifestyle improvement programs tailored to each individual. Its chatbot presented them in the form of behavioral goals and lectures from virtual nurses.
While patients used the app for 48 weeks, they also received standard outpatient care for NASH from live physicians, who also promoted the use of the app and provided additional education related to NASH.
The patients underwent liver biopsies within 90 days prior to beginning the study and at the end of 48 weeks. The researchers compared the changes in these patients versus those in a hypothetical control group, which they based on the placebo group in a previous study.
In the patients who used the app, the mean NAS change from baseline to week 48, the main endpoint, was –2.05 (95% confidence interval, –3.00 to –1.11). This result was statistically significant compared with the hypothetical control group, in which the mean change in NAS was –0.7 (P < .001).
In 11 of the patients, NAS decreased by at least 2 points without worsening of liver fibrosis. In eight patients, the researchers observed resolution of steatohepatitis, which they defined as disappearance of hepatocyte ballooning.
In 12 patients with stage F2 or F3 fibrosis, the average stage went from 2.5 to 2.0 (P = .02). No patient with stage F1 fibrosis showed a reduction in fibrosis stage. The scores for steatosis decreased in 11 patients, for lobular inflammation in 9 patients, and for ballooning in 10 patients.
The patients lost an average of 8.3% of their body weight, which was significant, compared with their baseline (P < .001). The patients also notched significant reductions in average serum levels of AST, ALT, gamma-glutamyltransferase, alkaline phosphatase, and triglycerides.
The researchers noted that the lack of a real control group and the small size of the study population limited the importance of their findings. A larger randomized, controlled trial is needed to confirm their results.
During the study, physicians browsed the patients’ data and provided them with feedback about it, the researchers wrote. But the study did not measure the amount of time the physicians spent on this activity.

FROM THE AMERICAN JOURNAL OF GASTROENTEROLOGY
A bold national plan to eliminate HCV by 2050
WASHINGTON – “We don’t get to use the ‘eliminate’ word all that often with a disease that’s taking thousands or tens of thousands – or worldwide, hundreds of thousands – of lives every year, but we have that opportunity with hepatitis C.”
So said Francis S. Collins, MD, PhD, special projects advisor to the Executive Office of the President of the United States, and former director of the National Institutes of Health, speaking at a special session outlining ambitious goals for a national plan to eliminate hepatitis C virus (HCV) infections by the year 2050.
The session was held at the annual meeting of the American Association for the Study of Liver Diseases.
A public health crisis
Dr. Collins labeled HCV a public health crisis, citing statistics from the Centers for Disease Control and Prevention that show that the rate of reported acute HCV infection cases increased 400% between 2010 and 2020, with the highest rates among young adults aged 20-39 years.
In addition, an estimated 2.4 million people in the United States are living with chronic HCV infections, but as many as 40% of these people are unaware of their infection, despite broad recommendations for the screening of all adults aged 18 years and older, he said.
“Our goal is to try to do something to change this,” Dr. Collins said. He noted that for the past 8 years we have had highly effective oral agents that don’t just treat the disease but cure it – 95%-97% of the time, with only 8-12 weeks of oral therapy and relatively few side effects.
“A wonderful story, one of the most exciting stories that’s come out of biomedical research in the last couple of decades,” he said.
Yet Dr. Collins also acknowledged that the task of developing a national plan is daunting, despite that pharmaceutical triumph.
National pharmacy claims data show that the number of persons treated for HCV with direct-acting antiviral agents (DAAs) in the United States declined from a high of 164,247 in 2015 to 83,740 in 2020.
Furthermore, CDC data from 2019 and 2020 show that, of persons with a diagnosis of HCV infection, only 23% of those on Medicaid, 28% of those on Medicare, and 35% of those with private insurance were treated for their infections.
“We have a huge gap here between the ability to know you have the disease and to get treatment, and we don’t see the numbers here for the uninsured, or people in prisons, but they’re probably much worse,” he said.
Obstacles abound, as do ways to overcome them
Current barriers to treatment include the aforementioned lack of awareness of infection, a “clunky” two-step diagnosis requiring an antibody test followed by an RNA or core antigen test necessitating three visits often separated by several weeks, and the high cost of treatment (around $90,000 per patient).
In addition, insurers commonly require proof that patients remain sober for extended periods, insist that treatment monitoring be performed by specialists only, and often approve treatment only for those patients who have documented evidence of liver damage.
“Does that make sense to you?” Dr. Collins asked. “You’ve got a cure for a liver disease, and you have to wait and show that the liver’s been damaged before you receive it? That just doesn’t fit,” he said.
Dr. Collins also pointed out that we’re dealing with hard-to-reach populations (underserved, uninsured, justice-involved), and people who are in tough times. “Anything that you put in the way as a barrier is going to make this worse in terms of its ability to be implemented,” he said.
To demonstrate how a coordinated HCV-elimination program could work, Dr. Collins pointed to a Medicaid cohort study in Louisiana conducted from July 2019 through December 2021, in which 8,867 patients started on therapy, 7,763 (88%) completed therapy, and 5,882 (66%) returned for testing. Of those tested, 5,285 (90%) had sustained virologic responses.
Another model of a hepatitis C elimination program was provided by the Veterans Health Administration. They received funding for an effort for all veterans, and in the space of 7 years were able to reach out even to some of their difficult-to-reach populations and achieve high diagnosis and treatment rates in a way that could be a model for what we would want to do across the nation, Dr. Collins noted.
Doing the math
Also at the session, Jagpreet Chhatwal, PhD, director of the Massachusetts General Hospital Institute for Technology Assessment and associate professor of radiology at Harvard Medical School, Boston, described outcomes projected by a mathematical simulation model of the HCV epidemic that he and his colleagues developed.
The HEP-SIM (Hepatitis C Disease Burden Simulation) model evaluates HCV prevalence trends, the number needed to screen and treat to eliminate HCV, HCV-associated clinical outcomes, the cost of an elimination program, and the cost savings that could be realized from preventing long-term complications.
The model seeks to determine whether the upfront costs of a national HCV elimination program could be offset by savings down the road. Specifically, it assumes that within the next 5 years 1.31 million individuals would be diagnosed with HCV and projects that within that time frame 1.52 million would need to be treated to meet HCV elimination goals.
The model shows that, compared with the status quo, a concerted campaign of screening and treatment would prevent more than 10,000 HCV-related deaths by 2030, and 91,000 deaths by 2050.
A coordinated screening program is also projected to prevent 17,000 cases of hepatocellular carcinoma by 2030 and 108,000 cases by 2050, as well as avert 29,000 cases of decompensated cirrhosis by 2030 and 93,000 such cases by 2050.
The cost savings associated with an HCV elimination plan would also be substantial, Dr. Chhatwal said.
According to the model, over the next decade the cumulative costs associated with HCV would decline by $14.2 billion, compared with the status quo. Nearly 80% of those savings ($11.2 billion) would be in Medicare and Medicaid.
The total projected savings from 2024 through 2050 – in disease management, testing, treatment, and pragmatic costs – are estimated at $59.3 billion, Dr. Chhatwal said.
“This is unprecedented,” he said.
Getting it done
Rachael L. Fleurence, PhD, MSc, a health economist currently serving as a senior advisor in the Executive Office of the President, summarized efforts to build a national HCV elimination program with input from federal health care agencies, state health leaders, patients, advocacy groups, drug manufacturers, and insurers.
She noted that a large component and focus of the program will be working on diagnostic test development but also accelerating bringing tests into the United States that are currently unavailable here. “These include point-of-care RNA diagnostic tests, as well as core antigen laboratory tests,” she said.
The program will be designed to offer broad access to curative anti-HCV drugs through a national subscription model that would make DAAs available to Medicaid recipients, justice-involved populations, the uninsured, and American Indians and Alaskan Natives who receive care through the Indian Health Service.
“On the Medicare and commercial insurance fronts, we’re still exploring different approaches, including potentially a co-pay assistance for Medicare beneficiaries, as well as working with commercial insurers to reduce barriers to access,” she said.
The program would also involve screening strategies extending to more settings, especially for high-risk populations, expanding the number of providers allowed to screen and treat HCV infections through telehealth, ensuring incentives for providers, and increasing the number of community health workers and case workers to improve linkage to care.
The next steps for the program would include funding to support the NIH’s RADx diagnostics program to accelerate access to testing, planning for the subscription model for DAA purchase, and launching pilot programs with the CDC, the Health Resources and Services Administration, the Substance Abuse and Mental Health Services Administration, and the Indian Health Service.
A call to action
Dr. Collins ended this portion of the program with an exhortation to AASLD members to do their part.
“We need your help,” Dr. Collins said. “This is a bold initiative, but it’s an opportunity. It’s even a responsibility. If we can actually succeed at this kind of outreach and save lives, and at the same time save money, how can we not do that?”
Dr. Collins, Dr. Chhatwal, and Dr. Fleurence each reported having no financial conflicts.

AT THE LIVER MEETING
Exosomes may drive HBV spread
Hepatitis B virus (HBV), which can lead to acute and chronic hepatitis, infects more than 2 billion people worldwide, according to serological evidence. Although vaccines and treatments are available, there are approximately 1.5 million new HBV infections each year globally.
A new study has revealed a key step in the HBV life cycle: Researchers found that HBV virions can be released within exosomes, which are capable of infecting neighboring cells. The authors, led by Qingyan Wu of the department of virology, Paul-Ehrlich-Institute, Langen, Germany, suggest this strategy may help the virus escape immune surveillance and target a new hepatocyte.
The study was published online in Cellular and Molecular Gastroenterology and Hepatology.
The researchers isolated exosomes from the supernatants of HBV-producing cells using exosomal and HBV markers. Electron microscopy using ultrathin sectioning along with immunogold labeling confirmed the presence of intact HBV virions in exosomes. The ultracentrifugation enabled the separation of the free virion fraction from the virions enclosed in exosomes. These findings fit in with previous discoveries of quasi-enveloped hepatitis A virus and hepatitis E virus.
The exosomes released free HBV virion and naked capsid after exposure to detergent. Cellular exposure to exosome morphogenesis inhibitors interfered with the release of exosome-packaged HBV. The researchers also observed large HBV surface antigens (LHB) on the external surface of the exosomes and found that the antigens allowed the exosome to infect susceptible cells through interaction with the sodium-taurocholate co-transporting polypeptide. LHB may also play an additional role in infectivity by countering the ability of antibodies to neutralize HBV.
However, the researchers also found that an LHB-specific neutralizing antibody inhibited infection of differentiated HepaRG cells with exosome-containing HBV. One explanation is that the antibody blocks the interaction between LHB and the target cell. Another is that the exosome disassembles near the target cell membrane and releases the virus, which is then blocked by the antibody since it can block entry of released virus.
To investigate the release pathway, the researchers used three different exosome release inhibitors and found that all three interfered with HBV exosomal release. They also found that cells deficient in the exosome proteins Alix and syntenin did not release exosomal HBV.
Alix appears to be involved in HBV exosomal release, as evidenced by the fact that release of exosomal HBV is boosted in Alix-deficient cells following rescue through overexpression of mCherry-Alix fusion construct. Overexpression of mCherry-Alix had no effect on release of free HBV virions.
The researchers also found evidence that two other exosomal proteins, CD63 and TSG101, play a role in incorporation of LHBs in the HBV envelope, as well as release of HBV through interactions with the protein alpha-taxilin. CD63 and TSG101 are also critical to the formation of exosomes, and the authors suggest further research into their functioning could be fruitful.
Whether exosome-released HBV results from crosstalk between the virus and host cells still needs to be determined. If host factors play a role in connecting HBV to exosomes, it will be interesting to work out which conditions trigger this process, as well as determine which events trigger the release of free virus through multivesicular bodies.
The researchers posit that LHBs could perform a similar function as classical hepatitis B surface antigens and filaments in foiling the immune response. Such a function would require that the virus escape from antibodies before opsonin proteins tag the antigens. It’s also possible that LHBs enable infection of nonhepatic tissues, though this would likely be inefficient.
Many other host proteins have been observed in exosomes released by HBV-infected hepatocytes, suggesting that host proteins may play other roles. A proteomics analysis found proteasome subunit proteins in HepAD38-derived exosomes. The authors suggest that those proteins may allow the exosomes to mediate transcellular immune regulation.
Subviral particles may enhance viral infection, and exosomes from HBV-positive cells may contribute, possibly through exosome surface LHBs, according to the authors. They found that an LHB-specific neutralizing antibody inhibited infection of differentiated HepaRG cells. One explanation is that the antibody blocks the interaction between LHB and the target cell. Another is that the exosome disassembles near the target cell membrane and releases the virus, which is then blocked by the antibody since it can block entry of released virus.
“This previously undiscovered strategy of sequestering HBV particles in exosomes could be a strategy to escape from the immune response and to target them, protected by the exosomal membrane, to the hepatocyte. Exosomes that carry HBV particles seem also to have the potential to deliver HBV to nonpermissive cells with low efficiency. This suggests that exosomes could be an additional factor that contributes to the spread of HBV,” the authors wrote.
The authors had no financial conflicts. This research was funded by the LOEWE Center ACLF, DRUID, the Germany Research Foundation, and the China Scholarship Council.
Viral cell entry and viral neutralization by antibodies are largely defined by the virion structure. Not surprisingly, viruses have evolved strategies to hijack cellular pathways for their morphogenesis to promote their dissemination and escape host immune responses. Hepatitis B viruses (HBV) are released as infectious enveloped virions from infected cells through the multivesicular body pathway. Moreover, excess HBV envelope proteins are exported as noninfectious subviral particles that can act as decoys to trap neutralizing antibodies.
Using cell culture models, investigators from the Hildt lab show in this study that a minority of enveloped virions are released within exosomes, the biogenesis of which is closely linked to HBV morphogenesis. The authors report that exosome-associated HBV can infect HBV-susceptible hepatoma cells and thus contribute to viral dissemination. The molecular mechanisms underlying infection of target cells by exosome-associated HBV and virions are largely comparable.
There is no major alternative entry pathway for HBV transported by exosomes, thus they can be inhibited by antibodies directed against the large HBV surface antigen (LHB) and the entry inhibitor Myrcludex. In addition to its role in exosome-cell interaction, the LHB on the exosome surface represents a target for neutralizing antibodies and, by providing an alternative target for humoral responses, could contribute to the evasion of infectious virions. The relative contribution of exosomes to HBV dissemination vs. escape remains to be determined.
Studies using HBV derived from the blood of HBV-infected patients are required to assess the relevance of these processes in vivo and if/how these are affected by antiviral therapies.

Hepatitis B virus (HBV), which can lead to acute and chronic hepatitis, infects more than 2 billion people worldwide, according to serological evidence. Although vaccines and treatments are available, there are approximately 1.5 million new HBV infections each year globally.
A new study has revealed a key step in the HBV life cycle: Researchers found that HBV virions can be released within exosomes, which are capable of infecting neighboring cells. The authors, led by Qingyan Wu of the department of virology, Paul-Ehrlich-Institute, Langen, Germany, suggest this strategy may help the virus escape immune surveillance and target a new hepatocyte.
The study was published online in Cellular and Molecular Gastroenterology and Hepatology.
The researchers isolated exosomes from the supernatants of HBV-producing cells using exosomal and HBV markers. Electron microscopy using ultrathin sectioning along with immunogold labeling confirmed the presence of intact HBV virions in exosomes. The ultracentrifugation enabled the separation of the free virion fraction from the virions enclosed in exosomes. These findings fit in with previous discoveries of quasi-enveloped hepatitis A virus and hepatitis E virus.
The exosomes released free HBV virion and naked capsid after exposure to detergent. Cellular exposure to exosome morphogenesis inhibitors interfered with the release of exosome-packaged HBV. The researchers also observed large HBV surface antigens (LHB) on the external surface of the exosomes and found that the antigens allowed the exosome to infect susceptible cells through interaction with the sodium-taurocholate co-transporting polypeptide. LHB may also play an additional role in infectivity by countering the ability of antibodies to neutralize HBV.
However, the researchers also found that an LHB-specific neutralizing antibody inhibited infection of differentiated HepaRG cells with exosome-containing HBV. One explanation is that the antibody blocks the interaction between LHB and the target cell. Another is that the exosome disassembles near the target cell membrane and releases the virus, which is then blocked by the antibody since it can block entry of released virus.

FROM CELLULAR AND MOLECULAR GASTROENTEROLOGY AND HEPATOLOGY
Poor NAFLD outcomes with increased VCTE-measured liver stiffness
according to new findings presented at the annual meeting of the American Association for the Study of Liver Diseases.
Although previous retrospective studies have suggested that increased liver stiffness, as measured by VCTE (FibroScan), is associated with increases in liver-related events, there is a paucity of prospective data, reported Samer Gawrieh, MD, from Indiana University, Carmel and Indianapolis. VCTE is a noninvasive measure of cirrhosis progression.
In their prospective cohort study of patients representing the entire spectrum of NAFLD, the progression to LSM-defined cirrhosis was independently associated with the risk for a composite clinical outcome of death, decompensation, hepatocellular carcinoma, or a Model for End Stage Liver Disease (MELD) score of greater than 15, he said.
Their findings show that “progression to LSM-defined cirrhosis by VCTE is strongly associated with poor clinical outcomes,” Dr. Gawrieh said.
Study findings
Investigators looked at prospective data on 894 patients with biopsy-proven NAFLD in the Nonalcoholic Steatohepatitis (NASH) Clinical Research Network database. The sample included patients with a minimum of two LSM readings taken from 2014 through 2022.
They defined LSM-defined cirrhosis as reaching LSM of greater than 14.9 kPa (90% specificity cutoff) among patients without cirrhosis on the baseline VCTE (a 90% sensitivity cutoff of LSM less than 12.1 kPa).
They also performed a histology-based subanalysis, including data only from those patients who had LSM within 6 months of a liver biopsy.
The median patient age was 60 years, 37% were male, and 80.9% were White and 11.5% were Hispanic/Latino. The median body mass index (BMI) was 32.
Out of all the patients, 119 (13.3%) had progression to LSM-defined cirrhosis.
At a median follow-up of 3.69 years for the 775 patients without LSM progression, 79 (10.2%) had one or more of the events in the composite clinical outcome.
In contrast, after a median 5.48 years of follow-up, 31 of the 119 patients with progression (26.1%) had one or more of the composite events (P < .0001).
The median rates of progression to LSM-defined cirrhosis in the overall cohort were 2% at 1 year, 11% at 3 years, and 16% at 5 years.
Researchers found a correlation between progression to LSM-defined cirrhosis and baseline histological fibrosis stage on biopsy, with a rate of 7% among those with no baseline fibrosis, 9% each for patients with stage I A-C or stage II fibrosis, 24% of those with baseline bridging fibrosis, and 25% of those with baseline cirrhosis.
A comparison of the time to a composite clinical outcome event between patients with progression to LSM-defined cirrhosis and those without progression showed that LSM-defined progression was associated with near doubling in risk, with a hazard ratio of 1.84 (P = .0039).
In a multivariate Cox regression analysis controlling for age, sex, race, BMI, diabetes status, and baseline LSM, only LSM-defined progression (HR, 1.93; P < .01) and age (HR, 1.03; P < .01) were significant predictors.
Dr. Gawrieh noted that while age was a statistically significant factor, it was only weakly associated.
“These data suggest that development of cirrhosis LSM criteria is a promising surrogate for clinical outcomes in patients with NAFLD,” Dr. Gawrieh concluded.
Progression definition questioned
Following the presentation, Nezam Afdhal, MD, chief of the division of gastroenterology, hepatology, and nutrition at Beth Israel Deaconess Hospital in Boston, questioned how 25% of patients who had biopsy-proven cirrhosis could progress to LSM-defined cirrhosis.
Dr. Gawrieh said that, according to inclusion criteria, the patients could not have LSM-defined cirrhosis with the sensitivity cutoff of 12.1 kPa, and that of the 10 patients with baseline cirrhosis in the cohort, all had LSM of less than 12.1 kPa. However, he admitted that because those 10 patients were technically not progressors to cirrhosis, they should have been removed from the analysis for clinical outcomes.
Mark Hartman, MD, a clinical researcher at Eli Lilly and Company in Indianapolis, said the study is valuable but noted that those patients who progressed tended to have higher LSM at baseline as well as a higher [fibrosis-4 score].
Dr. Gawrieh added that the investigators are exploring variables that might explain progression to cirrhosis among patients without high baseline liver stiffness, such as alcohol use or drug-induced liver injury.
The study was supported by the National Institutes of Health and the NASH Clinical Research Network institutions. Dr. Gawrieh disclosed research grants from NIH, Zydus, Viking, and Sonic Incytes, and consulting for TransMedics and Pfizer. Dr. Afdhal and Dr. Hartman reported no relevant financial relationships.

FROM THE LIVER MEETING
Midodrine may be comparable to albumin for PICD prevention in ACLF
WASHINGTON – , according to the results of a randomized controlled trial.
Albumin protected 80% of patients from PICD 6 days after paracentesis, whereas midodrine protected 84%, a difference that was not statistically significant. However, albumin was associated with a slightly higher incidence of adverse events and higher costs, said Mithun Sharma, MD, during his presentation at the annual meeting of the American Association for the Study of Liver Diseases.
Midodrine may be a safer and cost-effective option for these patients, said Dr. Sharma, of the department of hepatology and liver transplantation, AIG Hospitals, Hyderabad, India.
But he cautioned that given the small size of the open-label study, with only 25 patients in each arm, the results should be considered as proof of concept and need to be validated in larger studies.
PICD common in ACLF
PICD is caused by fluid shift during paracentesis, leading to a decrease in effective circulating blood volume.
The incidence of PICD after large-volume paracentesis in patients receiving albumin ranges from 12% to 20%, Dr. Sharma noted.
Albumin has been shown in several trials to be effective at reducing the incidence of PICD in patients undergoing paracentesis, but this agent requires IV infusion and is comparatively costly, he said.
In contrast, midodrine, a selective alpha-adrenergic agonist usually prescribed for orthostatic hypotension, may help to prevent PICD through its mechanism of action, maintaining mean arterial pressure (MAP).
In two small studies comparing albumin infusion in patients undergoing paracentesis with 8 liters of fluid removal, midodrine was either inferior to albumin or had no beneficial effect, Dr. Sharma said.
Patients with ACLF, however, have paracentesis with much lower fluid volumes, typically with less than 5 liters removed, and may be good candidates for midodrine.
Study details
Dr. Sharma and colleagues tested their hypothesis that in patients with ACLF undergoing modest-volume paracentesis, with fluid removal below 5 liters, midodrine could prevent PICD by increasing MAP, with an efficacy similar to that of intravenous 20% human albumin infusions.
They enrolled 50 patients with ACLF defined by Asian Pacific Association for the Study of the Liver criteria who were undergoing paracentesis with 3- to 4-liter fluid volumes.
They defined PICD as at least a 50% increase in plasma renin activity (PRA) over baseline on the 6th day following paracentesis.
The patients were randomly assigned to receive either intravenous 20% human albumin infusions toward the end of paracentesis or midodrine-hydrochloride 7.5 mg three times daily starting 2 hours before paracentesis. Because of the difference in drug delivery methods, the study could not be blinded to treatment type.
Patients’ mean arterial pressures were recorded daily, renal parameters and serum electrolytes were monitored on days 3 and 6, and blood samples were tested for PRA on day 1 and day 6.
The most common acute and chronic hepatic insults and baseline characteristics of the patients were similar between the groups, with alcohol-related liver disease the most common underlying etiology of cirrhosis.
The incidence of PICD at day 6, the primary endpoint, did not differ significantly between the groups, although mean PRA levels on day 6 were numerically higher in the midodrine group. There was a significant rise in the absolute PRA volume from baseline (P = .006), but this rise did not meet the PICD definition.
Researchers found no significant differences between the two groups in absolute change in PRA, and no significant changes in either group in MAP, creatinine, or sodium levels.
Complications and costs
PICD developed in four patients assigned to the albumin group and five patients assigned to the midodrine group; however, this difference was not significant. Fluid overload occurred in only one patient, in the albumin group.
No cases of hypertension or urinary retention arose in either group.
Grade I/II hepatic encephalopathy occurred 2-3 days after paracentesis in three patients on albumin and in two patients on midodrine.
Acute kidney injury was seen in three patients on albumin and in one patient on midodrine.
At 28 days after paracentesis, three patients in the albumin group had died, all from sepsis and multiorgan failure, while four patients in the midodrine group had died, three from sepsis and multiorgan failure and one from an upper gastrointestinal bleed.
Two patients in the albumin group and one patient in the midodrine group underwent liver transplant 1 month after paracentesis.
A cost-effectiveness analysis showed that the mean cost of albumin infusions was about sixfold higher than that of oral midodrine.
More data needed
Session moderator Shiv K. Sarin, MD, from the Institute of Liver and Biliary Sciences in New Delhi, India, who was not involved in the study, commented that while midodrine is a good drug and generally safe, he would wait to use it in patients who needed modest-volume paracentesis until more data are published.
Dr. Sarin also emphasized that albumin is “mandatory” for protecting patients who require large-volume paracentesis, and that it would be “unethical” not to use it in that clinical situation.
The study was internally supported. Dr. Sharma and Dr. Sarin have disclosed no relevant financial relationships.

WASHINGTON – , according to the results of a randomized controlled trial.
Albumin protected 80% of patients from PICD 6 days after paracentesis, whereas midodrine protected 84%, a difference that was not statistically significant. However, albumin was associated with a slightly higher incidence of adverse events and higher costs, said Mithun Sharma, MD, during his presentation at the annual meeting of the American Association for the Study of Liver Diseases.
Midodrine may be a safer and cost-effective option for these patients, said Dr. Sharma, of the department of hepatology and liver transplantation, AIG Hospitals, Hyderabad, India.
But he cautioned that given the small size of the open-label study, with only 25 patients in each arm, the results should be considered as proof of concept and need to be validated in larger studies.
PICD common in ACLF
PICD is caused by fluid shift during paracentesis, leading to a decrease in effective circulating blood volume.
The incidence of PICD after large-volume paracentesis in patients receiving albumin ranges from 12% to 20%, Dr. Sharma noted.
Albumin has been shown in several trials to be effective at reducing the incidence of PICD in patients undergoing paracentesis, but this agent requires IV infusion and is comparatively costly, he said.
In contrast, midodrine, a selective alpha-adrenergic agonist usually prescribed for orthostatic hypotension, may help to prevent PICD through its mechanism of action, maintaining mean arterial pressure (MAP).
In two small studies comparing albumin infusion in patients undergoing paracentesis with 8 liters of fluid removal, midodrine was either inferior to albumin or had no beneficial effect, Dr. Sharma said.
Patients with ACLF, however, have paracentesis with much lower fluid volumes, typically with less than 5 liters removed, and may be good candidates for midodrine.
Study details
Dr. Sharma and colleagues tested their hypothesis that in patients with ACLF undergoing modest-volume paracentesis, with fluid removal below 5 liters, midodrine could prevent PICD by increasing MAP, with an efficacy similar to that of intravenous 20% human albumin infusions.
They enrolled 50 patients with ACLF defined by Asian Pacific Association for the Study of the Liver criteria who were undergoing paracentesis with 3- to 4-liter fluid volumes.
They defined PICD as at least a 50% increase in plasma renin activity (PRA) over baseline on the 6th day following paracentesis.

FROM THE LIVER MEETING
Bepirovirsen: Is a ‘functional cure’ for HBV on the horizon?
Treatment with bepirovirsen led to sustained clearance of hepatitis B surface antigen (HBsAg) and hepatitis B virus (HBV) DNA for 24 weeks after the end of treatment for adults with chronic HBV in the phase 2b B-Clear study.
The study results were presented at the annual meeting of the American Association for the Study of Liver Diseases and were simultaneously published in The New England Journal of Medicine.
Currently, nucleoside/nucleotide analogue (NA) therapy is the recommended first-line therapy for patients with chronic HBV because it can inhibit viral replication.
However, fewer than 5% of patients have HBsAg loss after 12 months of NA therapy, which underscores the need for therapies that can achieve a “functional” cure, largely defined as sustained, undetectable levels of HBV DNA and HBsAg in the blood, with or without generation of protective antibodies against HBsAg, the researchers noted.
Bepirovirsen is a potential first-in-class antisense oligonucleotide that targets all HBV messenger RNA and acts to decrease levels of viral proteins.
The phase 2b B-Clear study enrolled 457 patients with chronic HBV; 227 were receiving NA therapy, and 230 were not.
Participants were randomly assigned to receive weekly subcutaneous injections of bepirovirsen 300 mg for 24 weeks; bepirovirsen 300 mg for 12 weeks, then 150 mg for 12 weeks; bepirovirsen 300 mg for 12 weeks, then placebo for 12 weeks; or placebo for 12 weeks, then bepirovirsen 300 mg for 12 weeks (groups 1, 2, 3, and 4, respectively).
The composite primary outcome was HBsAg level below the limit of detection and HBV DNA level below the limit of quantification maintained for 24 weeks after the end of bepirovirsen treatment, without newly initiated antiviral medication.
Bepirovirsen 300 mg weekly for 24 weeks (group 1) led to HBsAg and HBV DNA loss in 9% of patients receiving NA therapy and 10% of patients not receiving NA treatment, which was sustained for 24 weeks after the last dose.
For groups 2, 3, and 4, HBsAg and HBV DNA loss occurred in 9%, 3%, and 0%, respectively, of patients receiving NA therapy and 6%, 1%, and 0%, respectively, of patients not receiving NA treatment.
Patients with low baseline HBsAg levels (< 1,000 IU/mL) responded best to treatment with bepirovirsen. Among patients who received bepirovirsen 300 mg weekly for 24 weeks, the primary outcome was achieved by 16% of patients taking NA therapy and by 25% of patients not taking NA therapy.
Although a “relatively low percentage” of patients overall achieved the primary outcome, the study “indicates the possibility of enhanced efficacy with the selection of patients according to baseline characteristics (low HBsAg level at baseline), with combination therapies, or both,” the researchers wrote.
Adverse events with bepirovirsen included injection-site reactions, pyrexia, fatigue, and increased alanine aminotransferase (ALT) levels. Increases in ALT levels, which were more common in those not receiving NA therapy than in those receiving NA therapy (41% vs. 17%), led to two serious adverse events.
On the basis of phase 2b data, GlaxoSmithKline (GSK) plans to advance bepirovirsen into phase 3 development, according to a news release.
Further pursuit of bepirovirsen therapy is “certainly warranted, with the use of a dose of 300 mg per week for at least 24 weeks; indeed, the duration of therapy might be dictated best by HBsAg levels at baseline,” Jay H. Hoofnagle, MD, director of the liver disease research branch at the National Institute of Diabetes and Digestive and Kidney Diseases, wrote in an editorial in the New England Journal of Medicine.
Several critical questions remain, including whether HBsAg negativity will persist beyond 24 weeks, wrote Dr. Hoofnagle, who was not involved in the study.
It’s a question GSK is addressing in the B-Sure trial, which will follow participants for an additional 33 months, the study noted.
Other questions include when NA therapy can be safely stopped, what other factors predict response, and whether RNA therapy–induced loss of HBsAg materially improves long-term outcomes, Dr. Hoofnagle wrote.
“Bepirovirsen is just one RNA-based HBV therapy now being pursued. Several other antisense RNAs as well as the more malleable small interfering RNA molecules (‘-sirans’) are currently in early-phase clinical trials. A new era in the control of hepatitis B may be at hand with these most modern of therapies for this most ancient disease,” Dr. Hoofnagle noted.
The B-Clear study was supported by GSK. Several authors have disclosed relationships with the company. A complete list of author disclosures is available with the original article. Dr. Hoofnagle has disclosed no relevant financial relationships.

FROM THE LIVER MEETING
Steroids and G-CSF improve 90-day survival in severe alcoholic hepatitis
, researchers from India reported.
Among patients with SAH, the combination of G-CSF and prednisolone was associated with a 90-day survival rate of 88.1%, compared with 78.6% for patients assigned to G-CSF alone, and 64.3% for patients assigned to prednisolone alone (P = .03).
The G-CSF/prednisolone combination was also associated with significantly better steroid responsiveness, as determined by the Lille Model for Alcoholic Hepatitis, reported Shiv K. Sarin, MD, from the Institute of Liver and Biliary Sciences, New Delhi.
The drug combo in steroid-eligible patients also “reduces morbidity related to infections, rehospitalizations, and hepatic encephalopathy [and] reduces infection rates,” Dr. Sarin said at the annual meeting of the American Association for the Study of Liver Diseases. He did caution that the treatment requires close monitoring.
Prednisolone-only drawbacks
For patients with SAH, 30-day mortality ranges from 20%-50%. While some patients respond to treatment with corticosteroids, the response is often modest and limited in duration, Dr. Sarin said.
The STOPAH trial found that 15% of patients with SAH treated with prednisolone developed serious infections, compared with 8% of patients on placebo (P = .002), he noted.
Dr. Sarin also pointed to a recent worldwide study attempting to identify the optimal therapeutic window for steroid use in patients with alcoholic hepatitis. The investigators found that corticosteroids reduced 30-day mortality by 41% but only among patients with SAH, especially those with Model for End-Stage Liver Disease (MELD) scores between 25 and 39.
In previous studies, G-CSF has been shown to improve survival in patients with acute-on-chronic liver failure, including patients with SAH; in patients with SAH alone; and in steroid nonresponders, Dr. Sarin said.
Regenerative properties
In an interview with this news organization, Dr. Sarin said that although the use of G-CSF for patients with severe SAH is still under investigation at his center, “we are using G-CSF routinely for decompensated cirrhosis, where it is like an in vivo extension of regenerative stem cells. G-CSF recruits from bone marrow a lot of hematopoietic stem cells and mesenchymal stem cells.”
Dr. Sarin and colleagues hypothesized that G-CSF, with its immunomodulatory and regenerative properties, would be effective either alone or in combination with steroids in steroid-eligible patients with SAH.
To test this idea, they enrolled 126 patients ages 18-65 with SAH, defined as a Maddrey’s Discriminant Function (mDF) score greater than 32. They excluded patients with active infections, acute gastrointestinal bleeding, hepatorenal syndrome, an mDF score greater than 90, autoimmune hepatitis, hepatitis B or C, HIV, pregnancy, hemophagocytic lymphohistiocytosis, and those with hemoglobin below 8 and baseline white blood cell count over 25,000.
The patients were randomly assigned, 42 in each group, to receive one of the following:
- Prednisolone monotherapy 40 mg/day for 7 days, with the drug stopped at 7 days for patients with Lille scores above 0.45 or continued for up to 21 days for those with Lille scores below 0.45;
- Prednisolone plus G-CSF 300 mcg/day for 7 days, with those who achieve a Lille score above 0.45 stopping the steroid but continuing G-CSF, while those with Lille scores below 0.45 continuing on prednisolone for 21 days, plus G-CSF once every 3 days for 5 additional doses; or
- G-CSF monotherapy at a dose of 150-300 mcg/day for 7 days, then every 3 days for 28 days up to a total of 12 doses.
Improved response
In addition to its superior results on the primary endpoint of 90-day survival, combination therapy was associated with significantly better response to therapy. The mean Lille score at day 7 was 0.14 for the combination, compared with 0.21 for prednisolone alone and 0.28 for G-CSF alone (P = .002).
There were also significantly fewer nonresponders in the combination arm than either of the monotherapy groups (P = .03).
At 90 days, the rate of new infections was significantly higher among patients treated with prednisolone alone, at 35.7%, compared with 19% in the combination arm and 7.1% in the G-CSF alone group (P = .02). There were also significantly fewer skin and mucosal bleeding episodes with the combination (19% vs, 25% and 35.7% with prednisolone and G-CSF monotherapies, respectively, P = .03), as well as lower rates of hepatic encephalopathy (9.5% vs. 47.5% and 25%, respectively, P < .01).
No differences in alcohol relapse rates were found among the three groups.
Patient selection important
“I know a lot of the G-CSF studies that have been conducted in the U.S. and Europe have all been negative,” said David Goldberg, MD, from the University of Miami, during the session. “Do you think there’s something unique in your patients, the microbiome or maybe genetics, that leads to such different results?” he asked Dr. Sarin.
European studies included patients with infections, acute kidney injury (AKI), or other comorbidities that were exclusion criteria in his study, Dr. Sarin noted.
“If you already have an infection, you already have an AKI, then it’s not a good patient for treatment, so I think the choice of patient is important,” he said.
The study was internally supported. Dr. Sarin and Dr. Goldberg report no relevant financial relationships.

For patients with SAH, 30-day mortality ranges from 20%-50%. While some patients respond to treatment with corticosteroids, the response is often modest and limited in duration, Dr. Sarin said.
The STOPAH trial found that 15% of patients with SAH treated with prednisolone developed serious infections, compared with 8% of patients on placebo (P = .002), he noted.
Dr. Sarin also pointed to a recent worldwide study attempting to identify the optimal therapeutic window for steroid use in patients with alcoholic hepatitis. The investigators found that corticosteroids reduced 30-day mortality by 41% but only among patients with SAH, especially those with Model for End-Stage Liver Disease (MELD) scores between 25 and 39.
In previous studies, G-CSF has been shown to improve survival in patients with acute-on-chronic liver failure, including patients with SAH; in patients with SAH alone; and in steroid nonresponders, Dr. Sarin said.
Regenerative properties
In an interview with this news organization, Dr. Sarin said that although the use of G-CSF for patients with severe SAH is still under investigation at his center, “we are using G-CSF routinely for decompensated cirrhosis, where it is like an in vivo extension of regenerative stem cells. G-CSF recruits from bone marrow a lot of hematopoietic stem cells and mesenchymal stem cells.”
Dr. Sarin and colleagues hypothesized that G-CSF, with its immunomodulatory and regenerative properties, would be effective either alone or in combination with steroids in steroid-eligible patients with SAH.
To test this idea, they enrolled 126 patients ages 18-65 with SAH, defined as a Maddrey’s Discriminant Function (mDF) score greater than 32. They excluded patients with active infections, acute gastrointestinal bleeding, hepatorenal syndrome, an mDF score greater than 90, autoimmune hepatitis, hepatitis B or C, HIV, pregnancy, hemophagocytic lymphohistiocytosis, and those with hemoglobin below 8 and baseline white blood cell count over 25,000.
The patients were randomly assigned, 42 in each group, to receive one of the following:
- Prednisolone monotherapy 40 mg/day for 7 days, with the drug stopped at 7 days for patients with Lille scores above 0.45 or continued for up to 21 days for those with Lille scores below 0.45;
- Prednisolone plus G-CSF 300 mcg/day for 7 days, with those who achieve a Lille score above 0.45 stopping the steroid but continuing G-CSF, while those with Lille scores below 0.45 continuing on prednisolone for 21 days, plus G-CSF once every 3 days for 5 additional doses; or
- G-CSF monotherapy at a dose of 150-300 mcg/day for 7 days, then every 3 days for 28 days up to a total of 12 doses.
Improved response
In addition to its superior results on the primary endpoint of 90-day survival, combination therapy was associated with significantly better response to therapy. The mean Lille score at day 7 was 0.14 for the combination, compared with 0.21 for prednisolone alone and 0.28 for G-CSF alone (P = .002).
There were also significantly fewer nonresponders in the combination arm than either of the monotherapy groups (P = .03).
At 90 days, the rate of new infections was significantly higher among patients treated with prednisolone alone, at 35.7%, compared with 19% in the combination arm and 7.1% in the G-CSF alone group (P = .02). There were also significantly fewer skin and mucosal bleeding episodes with the combination (19% vs, 25% and 35.7% with prednisolone and G-CSF monotherapies, respectively, P = .03), as well as lower rates of hepatic encephalopathy (9.5% vs. 47.5% and 25%, respectively, P < .01).
No differences in alcohol relapse rates were found among the three groups.
Patient selection important
“I know a lot of the G-CSF studies that have been conducted in the U.S. and Europe have all been negative,” said David Goldberg, MD, from the University of Miami, during the session. “Do you think there’s something unique in your patients, the microbiome or maybe genetics, that leads to such different results?” he asked Dr. Sarin.
European studies included patients with infections, acute kidney injury (AKI), or other comorbidities that were exclusion criteria in his study, Dr. Sarin noted.
“If you already have an infection, you already have an AKI, then it’s not a good patient for treatment, so I think the choice of patient is important,” he said.
The study was internally supported. Dr. Sarin and Dr. Goldberg report no relevant financial relationships.

, researchers from India reported.
Among patients with SAH, the combination of G-CSF and prednisolone was associated with a 90-day survival rate of 88.1%, compared with 78.6% for patients assigned to G-CSF alone, and 64.3% for patients assigned to prednisolone alone (P = .03).
The G-CSF/prednisolone combination was also associated with significantly better steroid responsiveness, as determined by the Lille Model for Alcoholic Hepatitis, reported Shiv K. Sarin, MD, from the Institute of Liver and Biliary Sciences, New Delhi.
The drug combo in steroid-eligible patients also “reduces morbidity related to infections, rehospitalizations, and hepatic encephalopathy [and] reduces infection rates,” Dr. Sarin said at the annual meeting of the American Association for the Study of Liver Diseases. He did caution that the treatment requires close monitoring.

FROM THE LIVER MEETING
Liver disease-related deaths rise during pandemic
according to new findings presented at the annual meeting of the American Association for the Study of Liver Diseases.
Between 2019 and 2021, ALD-related deaths increased by 17.6% and NAFLD-related deaths increased by 14.5%, Yee Hui Yeo, MD, a resident physician and hepatology-focused investigator at Cedars-Sinai Medical Center in Los Angeles, said at a preconference press briefing.
“Even before the pandemic, the mortality rates for these two diseases have been increasing, with NAFLD having an even steeper increasing trend,” he said. “During the pandemic, these two diseases had a significant surge.”
Recent U.S. liver disease death rates
Dr. Yeo and colleagues analyzed data from the Center for Disease Control and Prevention’s National Vital Statistic System to estimate the age-standardized mortality rates (ASMR) of liver disease between 2010 and 2021, including ALD, NAFLD, hepatitis B, and hepatitis C. Using prediction modeling analyses based on trends from 2010 to 2019, they predicted mortality rates for 2020-2021 and compared them with the observed rates to quantify the differences related to the pandemic.
Between 2010 and 2021, there were about 626,000 chronic liver disease–related deaths, including about 343,000 ALD-related deaths, 204,000 hepatitis C–related deaths, 58,000 NAFLD-related deaths, and 21,000 hepatitis B–related deaths.
For ALD-related deaths, the annual percentage change was 3.5% for 2010-2019 and 17.6% for 2019-2021. The observed ASMR in 2020 was significantly higher than predicted, at 15.7 deaths per 100,000 people versus 13.0 predicted from the 2010-2019 rate. The trend continued in 2021, with 17.4 deaths per 100,000 people versus 13.4 in the previous decade.
The highest numbers of ALD-related deaths during the COVID-19 pandemic occurred in Alaska, Montana, Wyoming, Colorado, New Mexico, and South Dakota.
For NAFLD-related deaths, the annual percentage change was 7.6% for 2010-2014, 11.8% for 2014-2019, and 14.5% for 2019-2021. The observed ASMR was also higher than predicted, at 3.1 deaths per 100,000 people versus 2.6 in 2020, as well as 3.4 versus 2.8 in 2021.
The highest numbers of NAFLD-related deaths during the COVID-19 pandemic occurred in Oklahoma, Indiana, Kentucky, Tennessee, and West Virginia.
Hepatitis B and C gains lost in pandemic
In contrast, the annual percentage change in was –1.9% for hepatitis B and –2.8% for hepatitis C. After new treatment for hepatitis C emerged in 2013-2014, mortality rates were –7.8% for 2014-2019, Dr. Yeo noted.
“However, during the pandemic, we saw that this decrease has become a nonsignificant change,” he said. “That means our progress of the past 5 or 6 years has already stopped during the pandemic.”
By race and ethnicity, the increase in ALD-related mortality was most pronounced in non-Hispanic White, non-Hispanic Black, and Alaska Native/American Indian populations, Dr. Yeo said. Alaska Natives and American Indians had the highest annual percentage change, at 18%, followed by non-Hispanic Whites at 11.7% and non-Hispanic Blacks at 10.8%. There were no significant differences in race and ethnicity for NAFLD-related deaths, although all groups had major increases in recent years.
Biggest rise in young adults
By age, the increase in ALD-related mortality was particularly severe for ages 25-44, with an annual percentage change of 34.6% in 2019-2021, as compared with 13.7% for ages 45-64 and 12.6% for ages 65 and older.
For NAFLD-related deaths, another major increase was observed among ages 25-44, with an annual percentage change of 28.1% for 2019-2021, as compared with 12% for ages 65 and older and 7.4% for ages 45-64.
By sex, the ASMR increase in NAFLD-related mortality was steady throughout 2010-2021 for both men and women. In contrast, ALD-related death increased sharply between 2019 and 2021, with an annual percentage change of 19.1% for women and 16.7% for men.
“The increasing trend in mortality rates for ALD and NAFLD has been quite alarming, with disparities in age, race, and ethnicity,” Dr. Yeo said.
The study received no funding support. Some authors disclosed research funding, advisory board roles, and consulting fees with various pharmaceutical companies.
