Androgenetic Alopecia: Study Finds Efficacy of Topical and Oral Minoxidil Similar

Article Type
Changed
Fri, 04/12/2024 - 07:25

A rigorously conducted trial in men with androgenetic alopecia found that low-dose oral minoxidil was as effective in promoting hair growth as was topical minoxidil.

Oral minoxidil, 5 mg once a day, “did not demonstrate superiority” over topical minoxidil, 5%, applied twice a day, after 24 weeks, reported Mariana Alvares Penha, MD, of the department of dermatology at São Paulo State University, in Botucatu, Brazil, and coauthors. Their randomized, controlled, double-blind study was published online in JAMA Dermatology.

Topical minoxidil is approved by the US Food and Drug Administration (FDA) for androgenetic alopecia (AGA), but there has been increasing interest worldwide in the use of low-dose oral minoxidil, a vasodilator approved as an antihypertensive, as an alternative treatment.

The trial “is important information that’s never been elucidated before,” Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, said in an interview. The data, he added, can be used to reassure patients who do not want to take the oral form of the drug that a topical is just as effective.

“This study does let us counsel patients better and really give them the evidence,” said Shari Lipner, MD, PhD, associate professor of clinical dermatology at Weill Cornell Medicine, New York, who was also asked to comment on the results.

Both Dr. Lipner and Dr. Friedman said the study was well-designed.



The investigators enrolled 90 men aged 18-55; 68 completed the trial. Most had mild to moderate AGA. Men were excluded if they had received treatment for alopecia in the previous 6 months, a history of hair transplant, cardiopathy, nephropathy, dermatoses involving the scalp, any clinical conditions causing hair loss, or hypersensitivity to minoxidil.

They were randomized to receive either 5 mg of oral minoxidil a day, plus a placebo solution to apply to the scalp, or topical minoxidil solution (5%) applied twice a day plus placebo capsules. They were told to take a capsule at bedtime and to apply 1 mL of the solution to dry hair in the morning and at night.

The final analysis included 35 men in the topical group and 33 in the oral group (mean age, 36.6 years). Seven people in the topical group and 11 in the oral group were not able to attend the final appointment at 24 weeks. Three additional patients in the topical group dropped out for insomnia, hair shedding, and scalp eczema, while one dropped out of the oral group because of headache.

At 24 weeks, the percentage increase in terminal hair density in the oral minoxidil group was 27% higher (P = .005) in the vertex and 13% higher (P = .15) in the frontal scalp, compared with the topical-treated group.

Total hair density increased by 2% in the oral group compared with topical treatment in the vertex and decreased by 0.2% in the frontal area compared with topical treatment. None of these differences were statistically significant.

Three dermatologists blinded to the treatments, who analyzed photographs, determined that 60% of the men in the oral group and 48% in the topical group had clinical improvement in the frontal area, which was not statistically significant. More orally-treated patients had improvement in the vertex area: 70% compared with 46% of those on topical treatment (P = .04).

 

 

Hypertrichosis, Headache

Of the original 90 patients in the trial, more men taking oral minoxidil had hypertrichosis: 49% compared with 25% in the topical formulation group. Headache was also more common among those on oral minoxidil: six cases (14%) vs. one case (2%) among those on topical minoxidil. There was no difference in mean arterial blood pressure or resting heart rate between the two groups. Transient hair loss was more common with topical treatment, but it was not significant.

Dr. Friedman said that the study results would not change how he practices, but that it would give him data to use to inform patients who do not want to take oral minoxidil. He generally prescribes the oral form, unless patients do not want to take it or there is a medical contraindication, which he said is rare.

“I personally think oral is superior to topical,” mainly “because the patient’s actually using it,” said Dr. Friedman. “They’re more likely to take a pill a day versus apply something topically twice a day,” he added.

Both Dr. Lipner and Dr. Friedman said that they doubted that individuals could — or would want to — follow the twice-daily topical regimen used in the trial.

“In real life, not in the clinical trial scenario, it may be very hard for patients to comply with putting on the topical minoxidil twice a day or even once a day,” Dr. Lipner said.

However, she continues to prescribe more topical minoxidil than oral, because she believes “there’s less potential for side effects.” For patients who can adhere to the topical regimen, the study shows that they will get results, said Dr. Lipner.

Dr. Friedman, however, said that for patients who are looking at a lifetime of medication, “an oral will always win out on a topical to the scalp from an adherence perspective.”

The study was supported by the Brazilian Dermatology Society Support Fund. Dr. Penha reported receiving grants from the fund; no other disclosures were reported. Dr. Friedman and Dr. Lipner reported no conflicts related to minoxidil.

Bimekizumab Under FDA Review for Hidradenitis Suppurativa

Article Type
Changed
Fri, 04/12/2024 - 07:26

On April 4, 2024, the US Food and Drug Administration (FDA) accepted a supplemental Biologics License Application (sBLA) to review bimekizumab-bkzx, an interleukin (IL)-17A and IL-17F inhibitor, for the treatment of adults with moderate to severe hidradenitis suppurativa (HS).

The agency also accepted a second sBLA for a bimekizumab-bkzx 2-mL device.

The developments were announced in a press release from UCB, the manufacturer of bimekizumab-bkzx (Bimzelx), which was first approved in the United States in October 2023 for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy.



According to the press release, acceptance of the sBLA was based on results from two phase 3 studies known as BE HEARD I and BE HEARD II, which found that bimekizumab-bkzx showed clinically meaningful improvements compared with placebo at week 16 and were sustained to week 48. If approved, this would be the first HS approval for bimekizumab-bkzx worldwide. In the European Union, it is approved for treating adults with psoriatic arthritis and axial spondyloarthritis, in addition to moderate to severe psoriasis.

According to the company, approval of the 2-mL injection device would mean that patients would have an alternative one-injection regimen option; currently, one dose for psoriasis is administered as two 1-mL injections. Full US prescribing information for bimekizumab-bkzx can be found here.

Liquid Biopsy Has Near-Perfect Accuracy for Early Pancreatic Cancer

Article Type
Changed
Mon, 04/15/2024 - 17:34

— A liquid biopsy assay that combines a microRNA signature and a well-known biomarker for pancreatic cancer has demonstrated an accuracy of 97% for detecting stage I/II pancreatic ductal adenocarcinoma, the most common type of pancreatic cancer.

It is quite encouraging to know we have a blood test that could potentially find this disease early, said Ajay Goel, PhD, a molecular diagnostics specialist at City of Hope in Duarte, California, who presented the findings at the annual meeting of the American Association for Cancer Research (AACR).

Dr. Goel and colleagues developed a signature for pancreatic cancer based on microRNAs identified in the exomes shed from pancreatic cancers and cell-free DNA markers found in the blood of patients with the disease.

Their initial assay tested blood samples for this signature in a training cohort of 252 people in Japan, approximately 60% of whom had pancreatic cancer. The rest were healthy controls. The assay was then tested in validation cohorts of 400 subjects, half with pancreatic cancer and half controls, in China and South Korea.

In both the initial and validation tests, the microRNA assay had an accuracy of about 90% for stage I/II pancreatic cancer, already far better than commercially available assays.

In an additional validation cohort in the United States with 139 patients with pancreatic cancer and 193 controls at six centers across the country, the researchers found that adding carbohydrate antigen 19-9 — a well-known marker of pancreatic cancer — to the assay boosted the test’s accuracy to 97%.

The test performed the same whether the tumor was in the head or tail of the pancreas.

“We are very excited about this data,” said Dr. Goel.

The technology was recently licensed to Pharus Diagnostics for commercial development, which will likely include a prospective screening trial, he told this news organization.

Because pancreatic cancer is fairly uncommon, Dr. Goel did not anticipate the test being used for general screening but rather for screening high-risk patients such as those with newly diagnosed type 2 diabetes, a family history of pancreatic cancer, or predisposing genetic mutations.

“It should be a very inexpensive test; it doesn’t cost us much to do in the lab,” he added.

Study moderator Ryan Corcoran, MD, PhD, a gastrointestinal (GI) oncologist at Massachusetts General Hospital, Boston, saw the potential.

“As a GI oncologist, I know how lethal and hard to treat pancreatic cancer is,” he said. A test that could reliably detect pancreatic cancer early, with an acceptable false-positive rate, would be extremely useful.

“The cure rate is many, many times higher,” if we detect it before it has a chance to spread, he explained.

In the meantime, Dr. Goel said there’s more work to be done.

Almost 4,000 subjects have been enrolled in ongoing validation efforts, and efforts are underway to use the test to screen thousands of banked blood samples from the PLCO, a prospective cancer screening trial in healthy subjects.

The researchers also want to see if the test can distinguish benign pancreatic cysts from ones that turn cancerous.

The idea is to find the earliest possible signs of this disease to see if we can find it not “at the moment of clinical diagnosis, but possibly 6 months, 1 year, 2 years earlier” than with radiologic imaging, Dr. Goel said.

The work was funded by the National Cancer Institute and others. Dr. Goel is a consultant for Pharus Diagnostics and Cellomics. Dr. Corcoran is a consultant for, has grants from, and/or holds stock in numerous companies, including Pfizer, Novartis, Eli Lilly, and Revolution Medicines.

Almost 4,000 subjects have been enrolled in ongoing validation efforts, and efforts are underway to use the test to screen thousands of banked blood samples from the PLCO, a prospective cancer screening trial in healthy subjects.

The researchers also want to see if the test can distinguish benign pancreatic cysts from ones that turn cancerous.

The idea is to find the earliest possible signs of this disease to see if we can find it not “at the moment of clinical diagnosis, but possibly 6 months, 1 year, 2 years earlier” than with radiologic imaging, Dr. Goel said.

The work was funded by the National Cancer Institute and others. Dr. Goel is a consultant for Pharus Diagnostics and Cellomics. Dr. Corcoran is a consultant for, has grants from, and/or holds stock in numerous companies, including Pfizer, Novartis, Eli Lilly, and Revolution Medicines.

Statins Raise Diabetes Risk, but CV Benefit Outweighs It

Article Type

Thu, 04/11/2024 - 15:59

Statins raise the risks for increased glucose levels and the development of type 2 diabetes among people who don’t have it at baseline, but those risks are outweighed by the cardiovascular benefit, new data suggested.

The findings come from an analysis of individual participant data from a total of 23 randomized trials of statin therapy involving 154,664 individuals. In people without diabetes at baseline, statin therapy produces a dose-dependent increase in the risk for diabetes diagnosis, particularly among those whose glycemia marker levels are already at the diagnostic threshold.

Statins also tend to raise glucose levels in people who already have diabetes, but “the diabetes-related risks arising from the small changes in glycemia resulting from statin therapy are greatly outweighed by the benefits of statins on major vascular events when the direct clinical consequences of these outcomes are taken into consideration,” wrote the authors of the Cholesterol Treatment Trialists’ (CTT) Collaboration in their paper, published online in The Lancet Diabetes & Endocrinology.

Moreover, they say, “since the effect of statin therapy on measures of glycemia within an individual is small, there is likely to be little clinical benefit in measuring glucose concentrations and A1c values routinely after starting statin therapy with the aim of making comparisons to values taken before the initiation of a statin. However, people should continue to be screened for diabetes and associated risk factors and have their glycemic control monitored in accordance with current clinical guidelines.”

The CTT is co-led by Christina Reith, MBChB, PhD, and David Preiss, PhD, FRCPath, MRCP, both of the Nuffield Department of Population Health, University of Oxford, England.

In an accompanying editorial, Hertzel C. Gerstein, MD, and Marie Pigeyre, MD, PhD, both of McMaster University and Hamilton Health Sciences, Hamilton, Ontario, Canada, noted that the decreased absolute annual incidence of life-threatening cardiovascular outcomes with statins in people at high risk for type 2 diabetes “clearly exceeds the 0.1%-1.3% per year increased absolute incidence of type 2 diabetes.”

Dr. Gerstein and Dr. Pigeyre also said “these findings emphasize the importance of holistic care. As people at risk for cardiovascular outcomes are also at risk for type 2 diabetes, any prescription of a statin should be accompanied by promoting proven strategies to prevent or delay diabetes, such as modest weight reduction and increased physical activity. Finally, these findings emphasize the importance of always being alert for harmful adverse effects, even with the most beneficial and successful preventive therapies.”
 

Statins Raise Diabetes Risk, Glucose Levels Slightly

The meta-analysis of trials in the CTT Collaboration included individual participant data from 19 double-blind randomized, controlled trials with a median follow-up of 4.3 years comparing statins with placebo in a total of 123,940 participants, including 18% who had known type 2 diabetes at randomization. Also analyzed were another four double-blind trials of lower- vs higher-intensity statins involving a total of 30,724 participants followed for a median of 4.9 years, with 15% having diabetes at baseline.

In the 19 trials of low- or moderate-intensity statins vs placebo, statins resulted in a significant 10% increase in new-onset diabetes compared with placebo (rate ratio, 1.10), while high-intensity statins raised the risk by an also significant 36% (1.36). This translated to a mean absolute excess of 0.12% per year of treatment.

Compared with less intensive statin therapy, more intensive statin therapy resulted in a significant 10% proportional increase in new-onset diabetes (1.10), giving an absolute annual excess of 0.22%.

In the statin vs placebo trials, differences in A1c values from placebo were 0.06 percentage points higher for low- or moderate-intensity statins and 0.08 points greater for high-intensity statins.

Nearly two thirds (62%) of the excess cases of new-onset diabetes occurred among participants in the highest quarter of the baseline glycemia distribution for both low-intensity or moderate-intensity and high-intensity statin therapy.

And among participants who already had diabetes at baseline, there was a significant 10% relative increase in worsening glycemia (defined by adverse glycemic event, A1c increase of ≥ 0.5 percentage points, or medication escalation) with low- or moderate-intensity statins compared with placebo and a 24% relative increase in the high-intensity trials.

The Nuffield Department of Population Health has an explicit policy of not accepting any personal honoraria payments directly or indirectly from the pharmaceutical and food industries. It seeks reimbursement to the University of Oxford for the costs of travel and accommodation to participate in scientific meetings. Dr. Reith reported receiving funding to the University of Oxford from the UK National Institute for Health and Care Research Health Technology Assessment Programme and holding unpaid roles on the Clinical Data Interchange Standards Consortium as a board member and WHO as a scientific advisor. Dr. Preiss reported receiving funding to his research institution (but no personal funding) from Novartis for the ORION 4 trial of inclisiran, Novo Nordisk for the ASCEND PLUS trial of semaglutide, and Boehringer Ingelheim and Eli Lilly for the EMPA-KIDNEY trial and being a committee member for a National Institute for Health and Care Excellence guideline.

Early Olezarsen Results Show 50% Reduction in Triglycerides

Article Type
Changed
Thu, 04/11/2024 - 16:07

 

— A novel antisense therapy called olezarsen reduced triglycerides (TGs) by approximately 50% with either of the two study doses relative to placebo and did so with a low relative risk for adverse events, new data from a phase 2b trial showed.

“The reduction in triglycerides was greater than that currently possible with any available therapy,” reported Brian A. Bergmark, MD, an interventional cardiologist at Brigham and Women’s Hospital, Boston.

The drug also produced meaningful improvements in multiple other lipid subfractions associated with increased cardiovascular (CV) risk, including ApoC-III, very low–density lipoprotein (VLDL) cholesterol, ApoB, and non-LDL cholesterol. High-density lipoprotein (HDL) cholesterol levels were significantly raised.

The results were presented on April 7 as a late breaker at the American College of Cardiology (ACC) Scientific Session 2024 and published online simultaneously in The New England Journal of Medicine.
 

No Major Subgroup Failed to Respond

The effect was seen across all the key subgroups evaluated, including women and patients with diabetes, obesity, and severe as well as moderate elevations in TGs at baseline, Dr. Bergmark reported.

Olezarsen is a N-acetylgalactosamine–conjugated antisense oligonucleotide targeting APOC3 RNA. The results of this randomized trial, called BRIDGE-TIMI 73a, are consistent with other evidence that inhibiting expression of ApoC-III lowers the levels of TGs and other lipid subfractions to a degree that would predict clinical benefit.

In this study, 154 patients at 24 sites in North America were randomized in a 1:1 ratio to 50 or 80 mg olezarsen. Those in each of these cohorts were then randomized in a 3:1 ratio to active therapy or placebo. All therapies were administered by subcutaneous injection once per month.

Patients were eligible for the trial if they had moderate hypertriglyceridemia, defined as a level of 150-499 mg/dL, and elevated CV risk or if they had severe hypertriglyceridemia (≥ 500 mg/dL) with or without other evidence of elevated CV risk. The primary endpoint was a change in TGs at 6 months. Complete follow-up was available in about 97% of patients regardless of treatment assignment.

With a slight numerical advantage for the higher dose, the TG reductions were 49.1% for the 50-mg dose and 53.1% for the 80-mg dose relative to no significant change in the placebo group (P < .001 for both olezarsen doses). The reductions in ApoC-III, an upstream driver of TG production and a CV risk factor, were 64.2% and 73.2% relative to placebo (both P < .001), respectively, Dr. Bergmark reported.

In those with moderate hypertriglyceridemia, normal TG levels, defined as < 150 mg/dL, were reached at 6 months in 85.7% and 93.3% in the 40-mg and 80-mg dose groups, respectively. Relative to these reductions, normalization was seen in only 11.8% of placebo patients (P < .001).
 

TG Lowering Might Not Be Best Endpoint

The primary endpoint in this trial was a change in TGs, but this target was questioned by an invited ACC discussant, Daniel Soffer, MD, who is both an adjunct professor assistant professor of medicine at Penn Medicine, Philadelphia, and current president of the National Lipid Association.

Dr. Soffer noted that highly elevated TGs are a major risk factor for acute pancreatitis, so this predicts a clinical benefit for this purpose, but he thought the other lipid subfractions are far more important for the goal of reducing atherosclerotic cardiovascular disease (ASCVD).

Indeed, he said categorically that it is not TGs that drive ASCVD risk and therefore not what is the real importance of these data. Rather, “it is the non-HDL cholesterol and ApoB lowering” that will drive the likely benefits from this therapy in CV disease.

In addition to the TG reductions, olezarsen did, in fact, produce significant reductions in many of the lipid subfractions associated with increased CV risk. While slightly more favorable in most cases with the higher dose of olezarsen, even the lower dose reduced Apo C-III from baseline by 64.2% (P < .001), VLDL by 46.2% (P < .001), remnant cholesterol by 46.6% (P < .001), ApoB by 18.2% (P < .001), and non-HDL cholesterol by 25.4% (P < .001). HDL cholesterol was increased by 39.6% (P < .001).

These favorable effects on TG and other lipid subfractions were achieved with a safety profile that was reassuring, Dr. Bergmark said. Serious adverse events leading to discontinuation occurred in 0%, 1.7%, and 1.8% of the placebo, lower-dose, and higher-dose arms, respectively. These rates did not differ significantly.
 

 

 

Increased Liver Enzymes Is Common

Liver enzymes were significantly elevated (P < .001) for both doses of olezarsen vs placebo, but liver enzymes > 3× the upper limit of normal did not reach significance on either dose of olezarsen relative to placebo. Low platelet counts and reductions in kidney function were observed in a minority of patients but were generally manageable, according to Dr. Bergmark. There was no impact on hemoglobin A1c levels.

Further evaluation of change in hepatic function is planned in the ongoing extension studies.

Characterizing these results as “exciting,” Neha J. Pagidipati, MD, a member of the Duke Clinical Research Institute and an assistant professor at the Duke School of Medicine, Durham, North Carolina, said that identifying a drug effective for hypertriglyceridemia is likely to be a major advance. While elevated TGs are “one of the toughest” lipid abnormalities to manage, “there is not much out there to offer for treatment.”

She, like Dr. Soffer, was encouraged by the favorable effects on multiple lipid abnormalities associated with increased CV risk, but she said the ultimate clinical utility of this or other agents that lower TGs for ASCVD requires a study showing a change in CV events.

Dr. Bergmark reported financial relationships with 15 pharmaceutical companies, including Ionis, which provided funding for the BRIDGE-TIMI 73a trial. Soffer had financial relationships with Akcea, Amgen, Amryt, AstraZeneca, Ionis, Novartis, Regeneron, and Verve. Dr. Pagidipati had financial relationships with more than 10 pharmaceutical companies but was not involved in the design of management of the BRIDGE-TIMI 73a trial.

In this study, 154 patients at 24 sites in North America were randomized in a 1:1 ratio to 50 or 80 mg olezarsen. Those in each of these cohorts were then randomized in a 3:1 ratio to active therapy or placebo. All therapies were administered by subcutaneous injection once per month.

Patients were eligible for the trial if they had moderate hypertriglyceridemia, defined as a level of 150-499 mg/dL, and elevated CV risk or if they had severe hypertriglyceridemia (≥ 500 mg/dL) with or without other evidence of elevated CV risk. The primary endpoint was a change in TGs at 6 months. Complete follow-up was available in about 97% of patients regardless of treatment assignment.

With a slight numerical advantage for the higher dose, the TG reductions were 49.1% for the 50-mg dose and 53.1% for the 80-mg dose relative to no significant change in the placebo group (P < .001 for both olezarsen doses). The reductions in ApoC-III, an upstream driver of TG production and a CV risk factor, were 64.2% and 73.2% relative to placebo (both P < .001), respectively, Dr. Bergmark reported.

In those with moderate hypertriglyceridemia, normal TG levels, defined as < 150 mg/dL, were reached at 6 months in 85.7% and 93.3% in the 40-mg and 80-mg dose groups, respectively. Relative to these reductions, normalization was seen in only 11.8% of placebo patients (P < .001).
 

TG Lowering Might Not Be Best Endpoint

The primary endpoint in this trial was a change in TGs, but this target was questioned by an invited ACC discussant, Daniel Soffer, MD, who is both an adjunct professor assistant professor of medicine at Penn Medicine, Philadelphia, and current president of the National Lipid Association.

Dr. Soffer noted that highly elevated TGs are a major risk factor for acute pancreatitis, so this predicts a clinical benefit for this purpose, but he thought the other lipid subfractions are far more important for the goal of reducing atherosclerotic cardiovascular disease (ASCVD).

Indeed, he said categorically that it is not TGs that drive ASCVD risk and therefore not what is the real importance of these data. Rather, “it is the non-HDL cholesterol and ApoB lowering” that will drive the likely benefits from this therapy in CV disease.

In addition to the TG reductions, olezarsen did, in fact, produce significant reductions in many of the lipid subfractions associated with increased CV risk. While slightly more favorable in most cases with the higher dose of olezarsen, even the lower dose reduced Apo C-III from baseline by 64.2% (P < .001), VLDL by 46.2% (P < .001), remnant cholesterol by 46.6% (P < .001), ApoB by 18.2% (P < .001), and non-HDL cholesterol by 25.4% (P < .001). HDL cholesterol was increased by 39.6% (P < .001).

These favorable effects on TG and other lipid subfractions were achieved with a safety profile that was reassuring, Dr. Bergmark said. Serious adverse events leading to discontinuation occurred in 0%, 1.7%, and 1.8% of the placebo, lower-dose, and higher-dose arms, respectively. These rates did not differ significantly.
 

 

 

Increased Liver Enzymes Is Common

Liver enzymes were significantly elevated (P < .001) for both doses of olezarsen vs placebo, but liver enzymes > 3× the upper limit of normal did not reach significance on either dose of olezarsen relative to placebo. Low platelet counts and reductions in kidney function were observed in a minority of patients but were generally manageable, according to Dr. Bergmark. There was no impact on hemoglobin A1c levels.

Further evaluation of change in hepatic function is planned in the ongoing extension studies.

Characterizing these results as “exciting,” Neha J. Pagidipati, MD, a member of the Duke Clinical Research Institute and an assistant professor at the Duke School of Medicine, Durham, North Carolina, said that identifying a drug effective for hypertriglyceridemia is likely to be a major advance. While elevated TGs are “one of the toughest” lipid abnormalities to manage, “there is not much out there to offer for treatment.”

She, like Dr. Soffer, was encouraged by the favorable effects on multiple lipid abnormalities associated with increased CV risk, but she said the ultimate clinical utility of this or other agents that lower TGs for ASCVD requires a study showing a change in CV events.

Dr. Bergmark reported financial relationships with 15 pharmaceutical companies, including Ionis, which provided funding for the BRIDGE-TIMI 73a trial. Soffer had financial relationships with Akcea, Amgen, Amryt, AstraZeneca, Ionis, Novartis, Regeneron, and Verve. Dr. Pagidipati had financial relationships with more than 10 pharmaceutical companies but was not involved in the design of management of the BRIDGE-TIMI 73a trial.

Chronic Pain Linked to Accelerated Brain Aging

Article Type
Changed
Wed, 04/17/2024 - 11:43

The consequences of chronic musculoskeletal pain (CMP) may extend well beyond physical discomfort, potentially leading to faster aging of the brain, new research showed.

Using structural MRI data from more than 9000 adults with knee osteoarthritis (KOA) from the UK Biobank, investigators developed a brain age model to compare an individual’s brain age with their chronological age. Those with KOA showed a much faster rate of brain aging than healthy individuals.

The acceleration in brain aging was largely driven by the hippocampus and predicted memory decline and incident dementia during follow-up. Researchers identified a gene highly expressed in glial cells as a possible genetic factor for accelerated brain aging.

“We demonstrate the accelerated brain aging and cognitive decline in chronic musculoskeletal pain, in particular knee osteoarthritis, and provide a neural marker for early detection and intervention,” said co-first author Jiao Liu, PhD candidate, Chinese Academy of Sciences, Beijing.

“We are interested to know how to slow down the aging brain in chronic musculoskeletal pain patients. Proper exercise and lifestyle may reduce the risk,” Dr. Liu said.

The study was published online in Nature Mental Health.
 

Common Condition

CMP affects more than 40% of the world’s population and has been shown to have a harmful impact on cognitive function, although the exact mechanisms remain unclear. Prior research suggests that inflammatory markers associated with brain aging are higher in patients with CMP, suggesting a link between brain aging and CMP.

To investigate further, researchers explored patterns of brain aging in healthy cohorts and cohorts with four common types of CMP — chronic knee pain, chronic back pain, chronic neck pain, and chronic hip pain.

Using their brain age model, investigators observed significantly increased brain aging, or “predicted age difference,” only in individuals with KOA (P < .001). The observation was validated in an independent dataset (P = .020), suggesting a pattern of brain aging acceleration specific to KOA.

This acceleration was primarily driven by key brain regions involved in cognitive processing, including hippocampus and orbitofrontal cortex, and was correlated with longitudinal memory decline and dementia risk.

These data also suggest that the SLC39A8 gene, which is highly expressed in glial cells, might be a key genetic factor underpinning this acceleration.

“We not only revealed the specificity of accelerated brain aging in knee osteoarthritis patients, but importantly, we also provided longitudinal evidence suggesting the ability of our brain aging marker to predict future memory decline and increased dementia risk,” corresponding author Yiheng Tu, PhD, also with Chinese Academy of Sciences, Beijing, said in a news release.
 

A Future Treatment Target?

Commenting on this research, Shaheen Lakhan, MD, PhD, a neurologist and researcher based in Miami, noted that in this study, people with KOA showed signs of “faster brain aging on scans. Think of it as your brain wearing a disguise, appearing older than its actual years,” Dr. Lakhan said.

“Inflammation, a key player in osteoarthritis, might be playing a double agent, wreaking havoc not just on your joints but potentially on your memory too. Researchers even identified a specific gene linked to both knee pain and faster brain aging, hinting at a potential target for future treatments,” he added.

“Importantly, the increased risk of cognitive decline and dementia associated with chronic pain is likely one of many factors, and probably not a very high one on its own,” Dr. Lakhan noted.

The “good news,” he said, is that there are many “well-established ways to keep your brain sharp. Regular exercise, a healthy diet, and staying mentally stimulated are all proven strategies to reduce dementia risk. Think of chronic pain management as another tool you can add to your brain health toolbox.”

Support for the study was provided by the STI-2030 Major Project, the National Natural Science Foundation of China, the Scientific Foundation of the Institute of Psychology, Chinese Academy of Sciences, and the Young Elite Scientist Sponsorship Program by the China Association for Science and Technology. Dr. Liu and Dr. Lakhan had no relevant disclosures.

Arm Fat Raises CVD Risk in People With Type 2 Diabetes

Article Type
Changed
Wed, 04/10/2024 - 11:10

 

TOPLINE:

In people with type 2 diabetes (T2D), higher levels of arm and trunk fat are associated with an increased risk for cardiovascular disease (CVD) and mortality, while higher levels of leg fat are associated with a reduced risk for these conditions.

METHODOLOGY:

  • People with T2D have a twofold to fourfold higher risk for CVD and mortality, and evidence shows obesity management helps delay complications and premature death, but an elevated body mass index (BMI) may be insufficient to measure obesity.
  • In the “obesity paradox,” people with elevated BMI may have a lower CVD risk than people of normal weight.
  • Researchers prospectively investigated how regional body fat accumulation was associated with CVD risk in 21,472 people with T2D (mean age, 58.9 years; 60.7% men; BMI about 29-33) from the UK Biobank (2006-2010), followed up for a median of 7.7 years.
  • The regional body fat distribution in arms, trunk, and legs was assessed using bioelectrical impedance analysis.
  • The primary outcomes were the incidence of CVD, all-cause mortality, and CVD mortality.

TAKEAWAY:

  • Participants in the highest quartile of arm fat percentage (multivariate-adjusted hazard ratio [HR], 1.63; 95% CI, 1.29-2.05) and trunk fat percentage (HR, 1.27; 95% CI, 1.06-1.52) were at a higher risk for CVD than those in the lowest quartile.
  • However, participants in the highest quartile of leg fat percentage had a lower risk for CVD than those in the lowest quartile (HR, 0.72; 95% CI, 0.58-0.90).
  • A nonlinear relationship was observed between higher leg fat percentage and lower CVD risk and between higher trunk fat percentage and higher CVD risk, whereas a linear relationship was noted between higher arm fat percentage and higher CVD risk.
  • The patterns of association were similar for both all-cause mortality and CVD mortality. Overall patterns were similar for men and women.

IN PRACTICE:

“Our findings add to the understanding of body fat distribution in patients with T2D, which highlights the importance of considering both the amount and the location of body fat when assessing CVD and mortality risk among patients with T2D,” wrote the authors.

SOURCE:

The study led by Zixin Qiu, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China, was published online in The Journal of Clinical Endocrinology & Metabolism.

LIMITATIONS:

As body fat was measured only once at the beginning of the study, its changing association over time could not be assessed. Moreover, the findings were primarily based on predominantly White UK adults, potentially restricting their generalizability to other population groups. Furthermore, diabetes was diagnosed using self-reported medical history, medication, and hemoglobin A1c levels, implying that some cases may have gone undetected at baseline. 

DISCLOSURES:

This study was funded by grants from the National Natural Science Foundation of China, Hubei Province Science Fund for Distinguished Young Scholars, and Fundamental Research Funds for the Central Universities. The authors declared no conflicts of interest.

Can Short Cycles of a Fasting-Like Diet Reduce Disease Risk?

Article Type
Changed
Mon, 04/15/2024 - 17:31

 

TOPLINE:

Monthly cycles of a fasting-mimicking diet (FMD) may slow metabolic and immune system aging and reduce the risk for metabolic disease.

METHODOLOGY:

  • In two clinical trials, monthly 5-day cycles of an FMD (a proprietary line of plant-based, low-calorie, and low-protein food products) showed lower body weight, body fat, and blood pressure at 3 months.
  • Researchers assessed secondary outcomes for the impact of the diet on risk factors for metabolic syndrome and biomarkers associated with aging and age-related diseases.
  • This study looked at data from nearly half of the original 184 participants (aged 18-70 years) from the two clinical trials who went through three to four monthly cycles, adhering to 5 days of an FMD in either a crossover design compared with a normal diet or an intervention group compared with people following a Mediterranean diet.
  • Abdominal fat and hepatic fat were measured using an MRI in a subset of representative participants. The study also assessed metabolic blood markers and lipids and lymphoid-to-myeloid ratios (for immune aging).
  • Biological age estimation was calculated from seven clinical chemistry measures, and life expectancy and mortality risk estimates and a simulation of continued FMD cycles were based on the National Health and Nutrition Examination Survey.

TAKEAWAY:

  • In 15 volunteers measured by MRI, the body mass index (P = .0002), total body fat (P = .002), subcutaneous adipose tissue (P = .008), visceral adipose tissue (P = .002), and hepatic fat fraction (P = .049) reduced after the third FMD cycle, with a 50% reduction in liver fat for the five people with hepatic steatosis.
  • In 11 participants with prediabetes, insulin resistance (measured by homeostatic model assessment) reduced from 1.473 to 1.209 (P = .046), while A1c levels dropped from 5.8 to 5.43 (P = .032) after the third FMD cycle.
  • The lymphoid-to-myeloid ratio improved (P = .005) in all study participants receiving three FMD cycles, indicating an immune aging reversal.
  • The estimated median biological age of the 86 participants who completed three FMD cycles in both trials decreased by nearly 2.5 years, independent of weight loss.

IN PRACTICE:

“Together our findings indicate that the FMD is a feasible periodic dietary intervention that reduces disease risk factors and biological age,” the authors wrote.

SOURCE:

The study, led by Sebastian Brandhorst, PhD, Leonard Davis School of Gerontology, University of Southern California (USC), Los Angeles, and Morgan E. Levine, PhD, Department of Pathology, Yale School of Medicine, New Haven, Connecticut, was published in Nature Communications.

LIMITATIONS:

The study estimated the effects of monthly FMD cycles based on results from two clinical trials and included a small subset of trial volunteers. By study measures, the cohort was healthier and biologically younger than average people of similar chronological age. Of the 86 participants, 24 who underwent FMD cycles exhibited increased biological age. The simulation did not consider compliance, dropout, mortality, or the bias that may arise owing to enthusiastic volunteers. Estimated risk reductions assume an effect of change in biological age, which hasn’t been proven. Projections from extending the effects of FMD to a lifelong intervention may require cautious interpretation.

DISCLOSURES:

The study was supported by the USC Edna Jones chair fund and funds from NIH/NIA and the Yale PEPPER Center. The experimental diet was provided by L-Nutra Inc. Some authors declared an equity interest in L-Nutra, with one author’s equity to be assigned to the nonprofit foundation Create Cures. Others disclosed no conflicts of interest.

  • The lymphoid-to-myeloid ratio improved (P = .005) in all study participants receiving three FMD cycles, indicating an immune aging reversal.
  • The estimated median biological age of the 86 participants who completed three FMD cycles in both trials decreased by nearly 2.5 years, independent of weight loss.

IN PRACTICE:

“Together our findings indicate that the FMD is a feasible periodic dietary intervention that reduces disease risk factors and biological age,” the authors wrote.

SOURCE:

The study, led by Sebastian Brandhorst, PhD, Leonard Davis School of Gerontology, University of Southern California (USC), Los Angeles, and Morgan E. Levine, PhD, Department of Pathology, Yale School of Medicine, New Haven, Connecticut, was published in Nature Communications.

LIMITATIONS:

The study estimated the effects of monthly FMD cycles based on results from two clinical trials and included a small subset of trial volunteers. By study measures, the cohort was healthier and biologically younger than average people of similar chronological age. Of the 86 participants, 24 who underwent FMD cycles exhibited increased biological age. The simulation did not consider compliance, dropout, mortality, or the bias that may arise owing to enthusiastic volunteers. Estimated risk reductions assume an effect of change in biological age, which hasn’t been proven. Projections from extending the effects of FMD to a lifelong intervention may require cautious interpretation.

DISCLOSURES:

The study was supported by the USC Edna Jones chair fund and funds from NIH/NIA and the Yale PEPPER Center. The experimental diet was provided by L-Nutra Inc. Some authors declared an equity interest in L-Nutra, with one author’s equity to be assigned to the nonprofit foundation Create Cures. Others disclosed no conflicts of interest.

TOPLINE:

Monthly cycles of a fasting-mimicking diet (FMD) may slow metabolic and immune system aging and reduce the risk for metabolic disease.

METHODOLOGY:

  • In two clinical trials, monthly 5-day cycles of an FMD (a proprietary line of plant-based, low-calorie, and low-protein food products) showed lower body weight, body fat, and blood pressure at 3 months.
  • Researchers assessed secondary outcomes for the impact of the diet on risk factors for metabolic syndrome and biomarkers associated with aging and age-related diseases.
  • This study looked at data from nearly half of the original 184 participants (aged 18-70 years) from the two clinical trials who went through three to four monthly cycles, adhering to 5 days of an FMD in either a crossover design compared with a normal diet or an intervention group compared with people following a Mediterranean diet.
  • Abdominal fat and hepatic fat were measured using an MRI in a subset of representative participants. The study also assessed metabolic blood markers and lipids and lymphoid-to-myeloid ratios (for immune aging).
  • Biological age estimation was calculated from seven clinical chemistry measures, and life expectancy and mortality risk estimates and a simulation of continued FMD cycles were based on the National Health and Nutrition Examination Survey.

TAKEAWAY:

  • In 15 volunteers measured by MRI, the body mass index (P = .0002), total body fat (P = .002), subcutaneous adipose tissue (P = .008), visceral adipose tissue (P = .002), and hepatic fat fraction (P = .049) reduced after the third FMD cycle, with a 50% reduction in liver fat for the five people with hepatic steatosis.
  • In 11 participants with prediabetes, insulin resistance (measured by homeostatic model assessment) reduced from 1.473 to 1.209 (P = .046), while A1c levels dropped from 5.8 to 5.43 (P = .032) after the third FMD cycle.
  • The lymphoid-to-myeloid ratio improved (P = .005) in all study participants receiving three FMD cycles, indicating an immune aging reversal.

Using AI to Transform Diabetic Foot and Limb Preservation

Article Type
Changed
Wed, 04/10/2024 - 10:26

Diabetic foot complications represent a major global health challenge, with a high prevalence among patients with diabetes. A diabetic foot ulcer (DFU) not only affects the patient›s quality of life but also increases the risk for amputation.

Worldwide, a DFU occurs every second, and an amputation occurs every 20 seconds. The limitations of current detection and intervention methods underline the urgent need for innovative solutions.

Recent advances in artificial intelligence (AI) have paved the way for individualized risk prediction models for chronic wound management. These models use deep learning algorithms to analyze clinical data and images, providing personalized treatment plans that may improve healing outcomes and reduce the risk for amputation.

AI-powered tools can also be deployed for the diagnosis of diabetic foot complications. Using image analysis and pattern recognition, AI tools are learning to accurately detect signs of DFUs and other complications, facilitating early and effective intervention. Our group and others have been working not only on imaging devices but also on thermographic tools that — with the help of AI — can create an automated “foot selfie” to predict and prevent problems before they start.

AI’s predictive capabilities are instrumental to its clinical value. By identifying patients at high risk for DFUs, healthcare providers can implement preemptive measures, significantly reducing the likelihood of severe complications.

Although the potential benefits of AI in diabetic foot care are immense, integrating these tools into clinical practice poses challenges. These include ensuring the reliability of AI predictions, addressing data privacy concerns, and training healthcare professionals on the use of AI technologies.

As in so many other areas in our lives, AI holds the promise to revolutionize diabetic foot and limb preservation, offering hope for improved patient outcomes through early detection, precise diagnosis, and personalized care. However, realizing this potential requires ongoing research, development, and collaboration across the medical and technological fields to ensure these innovative solutions can be effectively integrated into standard care practices.

Dr. Armstrong is professor of surgery, Keck School of Medicine of University of Southern California, Los Angeles, California. He has disclosed the following relevant financial relationships: Partially supported by National Institutes of Health; National Institute of Diabetes; Digestive and Kidney Disease Award Number 1R01124789-01A1.

Telemedicine Reduces Rehospitalization, Revascularization in Post-PCI ACS Patients

Article Type
Changed
Thu, 04/11/2024 - 10:28

ATLANTA — Patients with acute coronary syndrome (ACS) who had a myocardial infarction or unstable angina and underwent percutaneous coronary intervention (PCI) had a 76% lower rate of hospital readmission after 6 months if they participated in a remote monitoring protocol compared with similar patients who had standard post-discharge care, results of a new trial suggest.

The TELE-ACS trial showed that at 6 months, telemedicine patients also had statistically significantly lower rates of post-discharge emergency department visits, unplanned coronary revascularizations, and cardiovascular symptoms, such as chest pain, shortness of breath and dizziness. However, the rates of major adverse cardiovascular events (MACE) were similar between the two groups. The protocol included consultation with a cardiologist who reviewed home-monitoring data.

“The team was able to aid in preventing unnecessary presentations and advised the patients to seek emergency care whenever was necessary,” Nasser Alshahrani, MSc, a clinical research fellow at Imperial College London, said while presenting the results at the American College of Cardiology meeting. “The TELE-ACS protocol provided a significant reduction in readmission rates post-ACS and other adverse events.” 

The study findings were published online simultaneously in the Journal of the American College of Cardiology.
 

Telemedicine Protocol

The trial, conducted from January 2022 to April 2023, randomly assigned 337 patients to telemedicine or standard care when they were discharged after PCI and had at least one cardiovascular risk factor. The telemedicine protocol consisted of 12-lead electrocardiogram belt, an automated blood-pressure monitor, and a pulse oximeter. 

Patients in the telemedicine arm initiated the remote monitoring protocol if they thought they had cardiac symptoms. The majority (86%) were men with what the study described as “a high preponderance of cardiovascular risk factors.” Average age was 58.1 years. 

If a telemedicine patient initiated the protocol, a cardiologist remotely assessed the patient’s symptoms and channeled the patient to the appropriate care pathway, whether reassuring the patient or sending them to a primary care physician or emergency department, or to call emergency services. Patients who didn’t get a call back from the cardiologist within 15 minutes were told to seek care in the standard clinical pathway.

Telemedicine patients were given the telemonitoring package and training in how to use the devices before they were discharged. They also received three follow-up quality control calls in the first two months to ensure they were using the equipment correctly. They kept the telemonitoring equipment for 8 months, but were followed out to 9 months. Six telemedicine patients dropped out while one standard care patient withdrew from the study.

Results showed that at 6 months, telemedicine patients had statistically significantly lower rates of post-discharge emergency department visits (25% vs 37%, P < .001), unplanned coronary revascularizations (3% vs 9%, P < .01) and cardiovascular symptoms, such as chest pain, shortness of breath and dizziness (a 13% to 18% difference for each symptom, P < .01).

MACE rates were similar between the two groups.

At 9 months, 3 months after the protocol ended, 20 telemedicine patients and 50 standard-care patients were readmitted to the hospital, while 52 and 73, respectively, went to the emergency department.

The telemedicine patients also had shorter hospital stays: an average of 0.5 and 1.2 days at 6 and 9 months, respectively, vs 1.5 and 1.8 days in the standard treatment arm (P < .001 for both).

Mr. Alshahrani noted several limitations with the study, namely that 86% of participants were men, and that the intervention was only offered to people who had smartphones. “The high level of support for the telemedicine group, with prompt cardiology responses, may be challenging to replicate outside a trial setting, requiring significant investment and training,” he added.
 

 

 

Human Element Key

In an interview from London after the presentation, lead author Ramzi Khamis, MB ChB, PhD, said, “This was quite a basic study. Really what we did was we integrated a clinical decision-making algorithm that we perfected with some quite novel but basic technology.” Future research should strive to add a home troponin test to the protocol and an artificial intelligence component, he said.

However, Dr. Khamis noted that human interaction was key to the success of the TELE-ACS trial. “The human factor is very important here and I think it would be really interesting to have a head-to-head comparison of human interaction with remote monitoring vs an AI-driven interaction,” he said. “I have my doubts that AI would be able to beat the human factor here.”

Lawrence Phillips, MD, medical director of outpatient cardiology at NYU Langone Heart, told this news organization that the study was appropriately powered to evaluate the telemedicine protocol, and that it could serve as a template for other studies of remote monitoring in cardiology. 

“I think that this study is forming the foundation of evolving telemedicine data,” he said. “It shows really interesting results, and I’m sure it’s going to be reproduced in different ways going forward.”

While other studies have shown the utility of telemedicine to decrease unnecessary hospitalizations, this study went one step further, Dr. Phillips said. “What was unique about this study was the package that they put together,” he added. “It was a combination of telehealth and being able to speak with someone when you have concerns with objective data of an electrocardiogram, blood-pressure cuff, and oxygen level assessment, which is an interesting approach having that ejective data with [a] subjective element.”

The trial received funding from the British Heart Foundation; King Khalid University, Abha, Saudi Arabia via The Saudi Arabian Cultural Bureau; Sansour Fund, Imperial Healthcare Charity; and Safwan Sobhan Fund at Imperial College London. Mr. Alshahrani and Dr. Khamis have no relevant relationships to disclose. Dr. Phillips has no relevant disclosures.
