Liver disease and death rates fall after hepatitis C treatment barriers are dismantled
As obstacles to hepatitis C treatment uptake were removed, rates of hepatitis-related liver disease in marginalized groups plummeted, according to a new study in Baltimore, published in Annals of Internal Medicine.
A community-based cohort study that follows current and former people who inject drugs (PWID) with hepatitis C documented drastic reductions in liver disease and death as effective oral antivirals became more readily accessible there between 2015 and 2019.
The researchers concluded that hepatitis C elimination targets are achievable. But, they warned, uptake is uneven, and more needs to be done to facilitate treatment.
“[The study] gives us a real-world perspective on what’s happening on the ground, in terms of people getting treated,” said first author Javier Cepeda, PhD, MPH, an assistant professor at the Johns Hopkins Bloomberg School of Public Health, Baltimore, in an interview. “Changing policy, reducing barriers, [and] getting them access to treatment really does have this really important public health benefit.”
” said Maria Corcorran, MD, MPH. Dr. Corcorran, an acting assistant professor for the department of medicine at the University of Washington, was not involved with the study. “It’s just further evidence that we need to really be linking people to care and getting people treated and cured.”
The World Health Organization has called for the disease’s global elimination by 2030. Cure rates top 95%. But, there are so many new cases and so many barriers to detection and treatment that how to develop and roll out a public health response is the most important question in the field, wrote study co-author David L. Thomas, MD, MPH, in a review article in The New England Journal of Medicine.
“Folks who inject drugs ... do well on hep C treatment and have similar rates of sustained virologic response or cure,” said Dr. Corcorran, who runs a low-barrier clinic for people experiencing homelessness.
But, she added, “there are barriers that are still put up to treatment in terms of who can treat and what insurance is going to cover.”
A look at a vulnerable population
The authors studied adults enrolled in ALIVE (AIDS Linked to the Intravenous Experience), a cohort study that has recruited current and former PWID in the Baltimore area since 1988.
Participants visit the clinic twice a year for health-related interviews and blood testing, including HIV serology, hepatitis C virus (HCV) antibody and RNA testing, and liver function tests. They are counseled about HCV testing and treatment but do not receive treatment through the study.
Beginning in 2006, researchers added liver stiffness measures (LSMs), a noninvasive measure conducted with transient elastography.
From 2006 to 2019, the authors followed 1,323 ALIVE participants with chronic HCV infection. The primary outcome was LSMs.
Less liver disease, fewer deaths
At baseline, participants’ median age was 49 years; 82% of participants were Black individuals, 71% percent were male, and two-thirds were HIV-negative.
Three percent reported receiving hepatitis C treatment in 2014, which increased to 39% in 2019.
Among 10,350 LSMs, 15% showed cirrhosis at baseline in 2006. In 2015, that rose to 19%, but by 2019, it had fallen to 8%.
By definition, 100% had detectable HCV RNA at baseline. In 2015, 91% still did. By 2019, that rate had fallen to 48%.
Undetectable HCV RNA correlated with lower log LSM in adjusted models (P < .001). It also correlated strongly with lower odds of liver cirrhosis, with an adjusted odds ratio of 0.28 (95% confidence interval, 0.17-0.45; P < .001). In addition, it correlated with lower risk for all-cause mortality, with an adjusted hazard ratio of 0.54 (95% CI, 0.38-0.77; P < .001).
Limitations include the fact that, although transient elastography is considered the most valid way to detect cirrhosis in people with hepatitis C, liver stiffness has not been validated as a measure of fibrosis among people with a sustained virologic response.
In addition, ALIVE participants are older and more likely to be African American individuals, compared with the general population of PWID in Baltimore, wrote co-author Shruti H. Mehta, PhD, a professor of epidemiology at Johns Hopkins University, Baltimore, in an email exchange with this news organization. That could affect generalizability.
Treatment is crucial
The first direct-acting antiviral (DAA) for hepatitis C was approved in 2011, and an oral fixed-dose combination antiviral was approved in 2014, ushering in treatments with cure rates far exceeding those with interferon-based therapy.
But until recently, Medicaid patients in Maryland seeking DAA therapy for hepatitis C required prior authorization, with initial restrictions related to disease stage, substance use, and provider type, according to Dr. Mehta.
Gradually, those restrictions were lifted, Dr. Mehta added, and all were eliminated by 2019.
Dr. Cepeda urges clinicians to treat patients infected with hepatitis C immediately.
“There are really important implications on both reducing liver disease progression and all-cause mortality,” he said.
“Hep C is just one part of a whole constellation of health care delivery [and] of treating all of the other potential problems that might need to be addressed – especially with people who inject drugs,” Dr. Cepeda added. “Getting them into care is really, really important.”
The study was funded by the National Institutes of Health. Dr. Cepeda and Dr. Corcorran report no relevant financial relationships. Dr. Mehta reports receiving payments or honoraria and travel support from Gilead Sciences, the makers of the oral hepatitis C medication ledipasvir/sofosbuvir (Harvoni), as well as equipment, materials, drugs, medical writing, gifts, or other services from Abbott, which sells hepatitis C diagnostics. Dr. Thomas reports ties to Excision Bio and to Merck DSMB.

Aging HIV patients face comorbidities and hospitalizations
Thanks to effective treatment, people with HIV are living longer. But as they age, they face higher rates of age-related comorbidities and hospitalizations, according to a recent study of hospitalized patients.
Decision-makers will need to allocate resources, train providers, and plan ways to manage chronic diseases, such as diabetes and cancer, among geriatric HIV inpatients, according to the authors.
“There will be more [HIV] patients with age-related chronic conditions at an earlier age and who will utilize or will have a unique need for [health care for] these geriatric conditions,” first author Khairul A. Siddiqi, PhD, University of Florida, Gainesville, said in an interview. “Eventually, that may increase inpatient resource utilization and costs.”
The study was published online in HIV Medicine.
Aging with HIV
Analyzing the National Inpatient Sample (NIS) of the Healthcare Cost and Utilization Project, the authors compared characteristics and comorbidities linked to hospital stays among people with HIV (HSWH) to those linked to hospital stays among people without HIV (HSWOH).
The NIS is a database of hospital records that captures 20% of discharges in the United States and covers all payers. Data in this analysis covered the years 2003-2015.
Among HSWH, patients aged 50 or older accounted for an increasing proportion over time, from fewer than 25% in 2003 to over 50% by 2015, the authors found. The subgroup aged 65-80 had risen from 2.39% to 8.63% by 2015.
The authors also studied rates of eight comorbidities, termed HIV-associated non-AIDS (HANA) conditions: cardiovascular, lung, liver, neurologic, and kidney diseases; diabetes; cancer; and bone loss.
The average number of these conditions among both HSWH and HSWOH rose over time. But this change was disproportionately high among HSWH aged 50-64 and those aged 65 and older.
Over the study period, among patients aged 65 or older, six of the eight age-related conditions the researchers studied rose disproportionately among HSWH in comparison with HSWOH; among those aged 50-64, five conditions did so.
The researchers are now building on the current study of HSWH by examining rates of resource utilization, such as MRIs and procedures, Dr. Siddiqi said.
Study limitations included a lack of data from long-term facilities, potential skewing by patients hospitalized multiple times, and the inherent limitations of administrative data.
A unique group of older people
Among people with HIV (PWH) in the United States, nearly half are aged 50 or older. By 2030, this group is expected to account for some 70% of PWH.
“We need to pay attention to what we know about aging generally. It is also important to study aging in this special population, because we don’t necessarily know a lot about that,” Amy Justice, MD, PhD, professor of medicine and of public health at Yale University, New Haven, Conn., said in an interview. Dr. Justice was not involved in the study.
The HIV epidemic has disproportionately affected people of color, men who have sex with men, and people with a history of injection drug use, Dr. Justice said.
“We don’t know about aging with [a] past history of injection drug use. We don’t even know much about aging with hepatitis C, necessarily,” she said. “So there are lots of reasons to pay some attention to this population to try to optimize their care.”
In addition, compared with their non–HIV-affected counterparts, these individuals are more susceptible to HANA comorbidities. They may experience these conditions at a younger age or more severely. Chronic inflammation and polypharmacy may be to blame, said Dr. Justice.
Given the burden of comorbidities and polypharmacy in this patient population, Dr. Siddiqi said, policy makers will need to focus on developing chronic disease management interventions for them.
However, Dr. Justice added, the risk for multimorbidity is higher among people with HIV throughout the age cycle: “It’s not like I turn 50 with HIV and all of a sudden all the wheels come off. There are ways to successfully age with HIV.”
Geriatric HIV expertise needed
Dr. Justice called the study’s analysis a useful addition to the literature and noted its implications for training.
“One of the biggest challenges with this large bolus of folks who are aging with HIV,” she said, “is to what extent should they be cared for by the people who have been caring for them – largely infectious disease docs – and to what extent should we really be transitioning their care to people with more experience with aging.”
Another key question, Dr. Justice said, relates to nursing homes and assisted-living facilities, whose staff may lack experience caring for HIV patients. Training them and hospital-based providers is crucial, in part to avoid key errors, such as missed antiretroviral doses, she said: “We need to really think about how to get non-HIV providers up to speed.”
That may begin by simply making it clear that this population is here.
“A decade ago, HIV patients used to have a lower life expectancy, so all HIV studies used to use 50 years as the cutoff point for [the] older population,” Dr. Siddiqi said. “Now we know they’re living longer.”
Added Dr. Justice: “Previously, people thought aging and HIV were not coincident findings.”
The study was funded by the Office of the Vice President for Research at the University of South Carolina. The authors and Dr. Justice disclosed no relevant financial relationships.
