HIV

TOPLINE:

Metabolic dysfunction-associated steatotic liver disease (MASLD) co-occurring with HIV infection does not appear to increase the risk for cirrhosis or hepatocellular carcinoma (HCC) compared with MASLD alone. However, the incidence of major adverse cardiovascular events (MACE) is significantly increased among patients with MASLD and HIV, a large study suggested.

METHODOLOGY:

• MASLD is highly prevalent in people living with HIV, but the impact of HIV on liver and cardiovascular disease (CVD) outcomes in people with MASLD remains unclear.
• To investigate, researchers created a propensity score-matched cohort of veterans with noncirrhotic MASLD, with and without HIV (920 patients in each group).
• They evaluated the incidence of cirrhosis, HCC, and MACE, as well as overall survival, among the two groups. They also assessed these outcomes in MASLD patients with HIV on the basis of whether they were on antiretroviral therapy (ART).

TAKEAWAY:

• During a median follow-up of 10.4 years in the MASLD with HIV group and 11.8 years in the MASLD-only group, the overall incidence of cirrhosis and HCC was similar in MASLD with vs without HIV (cirrhosis: 0.97 vs 1.06 per 100 person-years, P = .54; HCC: 0.26 vs 0.17 per 100,000 person-years, P = .23), regardless of ART use.

• In contrast, the incidence of MACE was significantly higher in MASLD with vs without HIV (5.18 vs 4.48 per 100 person-years, P = .03). The incidence also was higher in patients with MASLD and HIV who were not on ART compared with those on ART (5.83 vs 4.7 per 100 person-years, P = .07).

• Compared with MASLD without HIV, the overall 5-year survival was significantly lower in MASLD with HIV (91.3% vs 85.7%). In MASLD with HIV, receipt of ART was associated with a significantly higher 5-year survival than no ART (87.4% vs 81.6%).

IN PRACTICE:

“Ensuring timely and appropriate initiation of HIV treatment is critical in patients with MASLD who have concurrent HIV infection, as well as optimizing metabolic comorbidities that may also contribute to increased risks of CVD and increased mortality,” the authors wrote.

SOURCE:

The study, led by Robert J. Wong, MD, Division of Gastroenterology and Hepatology, Stanford University School of Medicine, Palo Alto, California, was published online in the American Journal of Gastroenterology.

LIMITATIONS:

The study cohort consisted predominantly of older men, which may limit generalizability to women and younger populations. Metabolic comorbidities are more common in veterans compared with the general population, potentially affecting the generalizability of the CVD risk findings.

DISCLOSURES:

The study was supported by an investigator-initiated research grant from Theratechnologies. Wong has received funding for his institution from Gilead Sciences, Exact Sciences, and Durect Corporation and has served as a consultant for Gilead Sciences.

The acronym AIDS is redundant, loaded with stigma, and potentially harmful, according to a group of specialists who suggest replacing the term with “advanced HIV.”

The acronym AIDS has “outlived its usefulness and we should transition toward a more descriptive language that aligns with contemporary challenges in HIV,” reports Isaac Núñez, MD, from the Department of Medical Education, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán in Mexico City, Mexico, and colleagues.

People generally associate the acronym AIDS with patients who have no available treatment options and a short life expectancy, said Dr. Núñez. That mischaracterization may affect treatment decisions by patients and clinicians and could result in exaggerated infection-control measures.

Using the HIV/AIDS combination erroneously implies equivalence and can mislead the public and clinicians, which the authors explained in their Viewpoint article published in The Lancet HIV.
 

Original Reason for the Term

AIDS, which stands for acquired immunodeficiency syndrome, was coined in 1982 by the US Centers for Disease Control and Prevention (CDC) to name a disease with an unknown cause that affected people with weakened cell-mediated immunity.

“When HIV was found to be the cause of the disease (labeled HIV in 1986), the term AIDS, strictly speaking, became unnecessary,” Dr. Núñez said.

AIDS was originally intended as a case definition for surveillance purposes, and treatment decisions were based on whether patients met the case definition for AIDS, he pointed out.

“The fact that some people still do so in this day and age shows that this is not only unhelpful, but misleading and even harmful,” he noted. Without the label AIDS, clinicians can focus on whether and for how long people have been on treatment, whether they recently switched treatment, and other factors that will help determine appropriate care.
 

Some Organizations Removed AIDS From Their Names

Some organizations have already removed AIDS from their names. For example, the International AIDS Society–USA, which issues guidelines on antiretroviral treatment, changed its name to the International Antiviral Society–USA. 

In 2017, the name of AIDS.gov was changed to HIV.gov. In its explanation, the group wrote, “Today, people with HIV who are diagnosed early, linked to care, start antiretroviral therapy, and take it as prescribed can achieve life-long viral suppression that prevents HIV infection from progressing to AIDS.”

A different view on the term AIDS comes from Greg Millett, MPH, vice president at the Foundation for AIDS Research (amfAR) and the director of amfAR’s Public Policy Office. 

Although he believes that AIDS is an anachronistic term, as a researcher for more than 30 years in the field; a policy director in Washington; a scientist; and a person living with HIV, “it feels like a distinction without a difference. At least from where I sit, there are far more pressing issues that we’re facing as an HIV community,” Millett shared. 

For instance, “we’re seeing that global, as well as domestic, HIV funding is in, by far, the most precarious position that I’ve ever seen in the field. Calling it AIDS or HIV makes no difference in trying to alleviate that jeopardy,” he said.

Millett also said that the stigma and persecution and, in some cases, criminalization of people living with HIV or AIDS is pervasive and won’t go away with a name change, which is a point the authors also acknowledged.

“We need to focus on the social determinants of health,” he said. “That is the thing that is going to move the needle among people living with HIV, not nomenclature.”

Millett likens the argument to the one between Black and African American. “As a Black American, I remember fierce debates in the early ‘90s over whether we should be called African Americans or Blacks. Some argued that African American carried greater dignity and would help with self-esteem and address inequities by emphasizing that we are American. Many others said that it doesn’t make a difference.”

“It is clear that being called African American has not fixed intractable issues like poverty, structural racism, or inequities in incarceration,” he pointed out.
 

End the Epidemic, Not the Name 

The authors misinterpret the impact of the term on stigma, said James W. Curran, MD, MPH, dean emeritus of the Rollins School of Public Health and professor of epidemiology and global health at Emory University, both in Atlanta, Georgia. The term AIDS “is more likely attributed to the fatal nature of the infection itself,” without treatment, he explained, and the mode of transmission, exacerbated by homophobia.

“The term has been in widespread use for 40 years and recognized worldwide,” Dr. Curran, who led the nation’s efforts in the battle against HIV and AIDS at the CDC for 15 years before joining Emory as dean, said.

He also worries about the continued trajectory of lives lost: “Over 35 million people worldwide have perished from HIV/AIDS, including over 500,000 per year now.”

Meanwhile, “global programs such as PEPFAR [the US President’s Emergency Plan for AIDS Relief] are under fire and threatened by Congress as no longer necessary. Removing AIDS from the terminology may add to confusion,” making people think “that the epidemic is over,” he said.

Although the authors argue that keeping the term may cause harm, eliminating it might worsen a different kind of harm. “There is a risk that abolishing the term will further de-emphasize the importance of the problem, with no significant impact on stigma,” Dr. Curran added.

On a November morning in 2022, James Messenger opened wide and swallowed a capsule like no other.

Messenger was no stranger to taking pills.

He’d first experimented with prescription opioids as a teenager in Morgantown, West Virginia, battled addiction on-and-off since, and known more than 70 people who had fatally overdosed. So, when asked to test a new “smart pill” that could detect an overdose in progress and call for help, he didn’t hesitate to join the study.

“I’ve lost pretty much every good friend I’ve ever had to this,” said Mr. Messenger. “This pill could save a lot of lives.”

The new Vitals Monitoring capsule he tested is just one example in a growing effort to radically rethink what the humble pill is capable of.

As far back as 1965, scientists introduced the Heidelberg capsule, an electronic pill that measured acidity from within the gut. In 1994, the University of Buffalo coined the term “smart pill” with a device promising to ferry medicine to a precise spot in the intestine, “like the tiny ship in the film Fantastic Voyage.” And in 2001, the US Food and Drug Administration (FDA) approved the first video capsule endoscope, a miniature-camera-toting pill that enabled noninvasive imaging of the small intestine.

Despite these milestones, the smart pill revolution has been slow to catch on due to cost, technological limitations, and some resistance among clinicians and patients.

But now, nearly 300 iterations are in various stages of development, according to a 2022 analysis. Advances in materials, imaging, and artificial intelligence (AI) are helping address everything from sleep apnea to HIV/AIDS to gut disorders via real-time tracking and real-time help.

“These technologies could enable us to shift the paradigm from ‘Let’s wait until the patient comes to us and find out what happened’ to ‘Let’s see how things are changing in real time, intervene now, and personalize that intervention,’ ” said Peter Chai, MD, associate professor of emergency medicine and health technology researcher at Brigham and Women’s Hospital in Boston.
 

Tracking Vitals From the Inside Out

Already, overdose-reversal agents like naloxone are saving lives. But more than 60% of overdoses occur when no one is around to administer them.

“While we need to focus on treatment, we also need to come up with more acute ways to save individuals when treatment doesn’t work or relapse occurs,” said James J. Mahoney III, PhD, director of addictions research at the Rockefeller Neuroscience Institute at West Virginia University (WVU), Morgantown.

Enter Celero Systems, a Massachusetts-based digital health company that has developed a vitamin-sized capsule packed with tiny sensors, microprocessors, and a radio antenna. It can measure breathing, heart rate, and core temperature — all from deep within the gut.

Respiratory distress is a hallmark early sign of an overdose. But it can be hard to monitor from a distance, especially in populations without access to a charged smartwatch.

Dr. Mahoney imagines a day when patients at risk could be given a weekly pill like Celero’s. If their respiratory rate drops below a dangerous level, it could alert loved ones or, better yet, release an overdose-reversal drug.

“It’s early days,” stressed Dr. Mahoney, whose team has been conducting pilot tests of the pill. “But initial data look promising.”

For one study, published in the journal Device in November 2023, the research team administered an overdose of fentanyl to anesthetized pigs with the pill in their stomachs. The capsule was able to detect respiratory depression within a minute and alert researchers via their laptop in time to step in.

When they gave the pill to 10 volunteers undergoing sleep studies at WVU, they found it could detect respiration rate with an accuracy of 93% compared with external monitoring devices — a feature that could also help diagnose sleep apnea or chronic obstructive pulmonary disease without expensive, intrusive tests.

Accuracy for heart rate was nearly 97%.

In another yet-to-be published trial, Dr. Mahoney tested the device with 10 volunteers in a residential treatment center to determine how well it could be tolerated.

Among the participants was Mr. Messenger, who said the thought of being tracked didn’t bother him.

“It was simple — just like taking a multivitamin,” said Mr. Messenger, now 34, sober, and working as a peer recovery support specialist at a hospital in his hometown. “It could be a great way to keep people alive long enough for them to get their head wrapped around the idea of treatment.”
 

Boosting Medication Adherence

At Brigham and Women’s Hospital, Dr. Chai is experimenting with a different smart pill — one he believes could help curb the ongoing HIV/AIDS epidemic.

Developed by Florida-based etectRx, the ID-Cap consists of a gelatin capsule embedded with a tiny radiofrequency transmitter, similar to the kind in retail antitheft devices. The capsule can be filled with a variety of medications. When swallowed, stomach acid dissolves the gel and activates the transmitter, which sends a signal to a receiver on a smartwatch, smartphone, or wall-mounted reader to confirm the medication was taken. If it isn’t, the patient’s smartphone or smart speaker might nudge them with a reminder or a family member might be notified.

In recent trials of men at a high risk for HIV, the system improved adherence to the once-daily prevention regimen pre-exposure prophylaxis (PrEP) by double digits.

“PrEP is almost 99% effective in preventing HIV, but you have to take it,” said Dr. Chai, who led the trials. “That seems like such a simple thing, but anyone who is chronically on medication can tell you just how difficult it can be.”

The pill is not the first designed to improve adherence. In 2017, the FDA approved the first digital ingestion tracking system, Abilify MyCite, for the treatment of schizophrenia and bipolar disorder. But its maker, Proteus Digital Health, filed for bankruptcy in 2020 after struggling to recruit patients willing to be tracked. (Some expressed privacy concerns. Others disliked the uncomfortable patch that received and forwarded the signal.)

More recent designs have been streamlined to ditch the patch, said etectRx senior vice president of operations Chris Carnes, PhD. And the cost of making a pill this kind of “smart” has come down to about a dollar.

So far, said Dr. Chai, in the patients he’s worked with, perceived benefits generally outweigh privacy concerns.

Studies are now underway in patients with heart disease and tuberculosis, and the company hopes to move into the aging and memory care space where medication-adherence is a serious problem.

“For us, or any company in this space, to succeed, you have to have a strong business case,” said Dr. Carnes. “If family members can keep their loved ones at home a little longer at an additional cost of $30 a month, that’s a no-brainer.”
 

Pillcams 2.0

Twenty-three years ago, the first video capsule endoscopy made it possible to image the small intestine via a tiny camera you swallow.

Such “pillcams” offered a more patient-friendly way to diagnose small bowel disorders, such as gastrointestinal bleeding and Crohn’s disease. Rather than undergoing sedation or anesthesia, as required during tube-based endoscopy, patients can go about their day as the pill painlessly passes through their gastrointestinal (GI) tract, capturing and recording data and images.

But the pills have their downsides.

Because they move passively, driven by movement in the intestine, they can miss trouble spots. Their ability to image the esophagus, stomach, and colon has proven limited. And unlike other procedures, like colonoscopy, they can’t intervene with therapy, like removing polyps.

The pillcam “had so much promise, to sort of revolutionize endoscopy, but it never really got the adoption that it seemed like it might,” said Andrew Meltzer, MD, professor of emergency medicine at the GW School of Medicine and Health Sciences in Washington.

That could soon change, he said, thanks to advances in locomotion and AI.

In a recent study of 40 patients, Dr. Meltzer tested a new magnetically controlled capsule endoscopy. Standing at a patient’s side, he could use a joystick to steer the pill around the stomach, capturing images in real time.

The pilot study, published in June 2023, found that the pill clearly identified six key stomach landmarks accurately 95% of the time and didn’t miss any lesions caught with traditional endoscopy. Notably, 80% of the patients preferred the pillcam over the tube.

“They are awake. They can go to work as soon as they leave. And it’s easy for them to tolerate,” Dr. Meltzer said.

More research is necessary, but Dr. Meltzer believes the technology could be particularly useful in the emergency department, allowing doctors to rule out high-risk bleeds in the stomach on the spot without admitting patients unnecessarily or making them return for a traditional scope.

“It has the potential to increase screening and provide more cost-effective care in emergencies,” he said.

It could also be useful in the telemedicine space, allowing a doctor to “drive” the pill from afar to diagnose a distant patient.

Someday, AI could enable the capsule to drive itself, so a doctor could merely press a button and wait. Or it could be adapted to treat what it finds, like administering a drug or cauterizing a bleed.

“If we can come up with a Mars rover which can explore other planets, we should be able to have something that can explore the stomach remotely,” Dr. Meltzer said.
 

Swallowing the Future

At the California Institute of Technology, researchers have developed a “location-aware” smart pill that uses magnetic fields to help pinpoint its location in the twists and turns of intestines. This could be useful for monitoring food in the GI tract to determine why things aren’t moving.

Other researchers are using AI models to enhance the transmission of video from inside the body and reduce the time it takes to interpret images.

One group at the Massachusetts Institute of Technology has developed a vibrating weight loss capsule designed to stimulate receptors in the gut to signal the brain that the person is full.

Not everyone is a fan of the smart-pill revolution. Some critics have raised concerns about privacy. Others fear that doctors risk yielding too much power to technology. Even those who are excited about the pills’ possibilities temper their optimism with caution.

None of these smart pills have gone mainstream yet in clinical practice, said Vivek Kaul, MD, professor of medicine at the University of Rochester Medical Center, Rochester, New York, and secretary general of the World Gastroenterology Organization.

Clinical validation, accessibility, and insurance coverage “will be critical in shaping their role,” he said. “But overall, it would be fair to state that this technology has come of age and the future is bright.”

On a November morning in 2022, James Messenger opened wide and swallowed a capsule like no other.

Messenger was no stranger to taking pills.

He’d first experimented with prescription opioids as a teenager in Morgantown, West Virginia, battled addiction on-and-off since, and known more than 70 people who had fatally overdosed. So, when asked to test a new “smart pill” that could detect an overdose in progress and call for help, he didn’t hesitate to join the study.

“I’ve lost pretty much every good friend I’ve ever had to this,” said Mr. Messenger. “This pill could save a lot of lives.”

The new Vitals Monitoring capsule he tested is just one example in a growing effort to radically rethink what the humble pill is capable of.

As far back as 1965, scientists introduced the Heidelberg capsule, an electronic pill that measured acidity from within the gut. In 1994, the University of Buffalo coined the term “smart pill” with a device promising to ferry medicine to a precise spot in the intestine, “like the tiny ship in the film Fantastic Voyage.” And in 2001, the US Food and Drug Administration (FDA) approved the first video capsule endoscope, a miniature-camera-toting pill that enabled noninvasive imaging of the small intestine.

Despite these milestones, the smart pill revolution has been slow to catch on due to cost, technological limitations, and some resistance among clinicians and patients.

But now, nearly 300 iterations are in various stages of development, according to a 2022 analysis. Advances in materials, imaging, and artificial intelligence (AI) are helping address everything from sleep apnea to HIV/AIDS to gut disorders via real-time tracking and real-time help.

“These technologies could enable us to shift the paradigm from ‘Let’s wait until the patient comes to us and find out what happened’ to ‘Let’s see how things are changing in real time, intervene now, and personalize that intervention,’ ” said Peter Chai, MD, associate professor of emergency medicine and health technology researcher at Brigham and Women’s Hospital in Boston.
 

Tracking Vitals From the Inside Out

Already, overdose-reversal agents like naloxone are saving lives. But more than 60% of overdoses occur when no one is around to administer them.

“While we need to focus on treatment, we also need to come up with more acute ways to save individuals when treatment doesn’t work or relapse occurs,” said James J. Mahoney III, PhD, director of addictions research at the Rockefeller Neuroscience Institute at West Virginia University (WVU), Morgantown.

Enter Celero Systems, a Massachusetts-based digital health company that has developed a vitamin-sized capsule packed with tiny sensors, microprocessors, and a radio antenna. It can measure breathing, heart rate, and core temperature — all from deep within the gut.

Respiratory distress is a hallmark early sign of an overdose. But it can be hard to monitor from a distance, especially in populations without access to a charged smartwatch.

Dr. Mahoney imagines a day when patients at risk could be given a weekly pill like Celero’s. If their respiratory rate drops below a dangerous level, it could alert loved ones or, better yet, release an overdose-reversal drug.

“It’s early days,” stressed Dr. Mahoney, whose team has been conducting pilot tests of the pill. “But initial data look promising.”

For one study, published in the journal Device in November 2023, the research team administered an overdose of fentanyl to anesthetized pigs with the pill in their stomachs. The capsule was able to detect respiratory depression within a minute and alert researchers via their laptop in time to step in.

When they gave the pill to 10 volunteers undergoing sleep studies at WVU, they found it could detect respiration rate with an accuracy of 93% compared with external monitoring devices — a feature that could also help diagnose sleep apnea or chronic obstructive pulmonary disease without expensive, intrusive tests.

Accuracy for heart rate was nearly 97%.

In another yet-to-be published trial, Dr. Mahoney tested the device with 10 volunteers in a residential treatment center to determine how well it could be tolerated.

Among the participants was Mr. Messenger, who said the thought of being tracked didn’t bother him.

“It was simple — just like taking a multivitamin,” said Mr. Messenger, now 34, sober, and working as a peer recovery support specialist at a hospital in his hometown. “It could be a great way to keep people alive long enough for them to get their head wrapped around the idea of treatment.”
 

Boosting Medication Adherence

At Brigham and Women’s Hospital, Dr. Chai is experimenting with a different smart pill — one he believes could help curb the ongoing HIV/AIDS epidemic.

Developed by Florida-based etectRx, the ID-Cap consists of a gelatin capsule embedded with a tiny radiofrequency transmitter, similar to the kind in retail antitheft devices. The capsule can be filled with a variety of medications. When swallowed, stomach acid dissolves the gel and activates the transmitter, which sends a signal to a receiver on a smartwatch, smartphone, or wall-mounted reader to confirm the medication was taken. If it isn’t, the patient’s smartphone or smart speaker might nudge them with a reminder or a family member might be notified.

In recent trials of men at a high risk for HIV, the system improved adherence to the once-daily prevention regimen pre-exposure prophylaxis (PrEP) by double digits.

“PrEP is almost 99% effective in preventing HIV, but you have to take it,” said Dr. Chai, who led the trials. “That seems like such a simple thing, but anyone who is chronically on medication can tell you just how difficult it can be.”

The pill is not the first designed to improve adherence. In 2017, the FDA approved the first digital ingestion tracking system, Abilify MyCite, for the treatment of schizophrenia and bipolar disorder. But its maker, Proteus Digital Health, filed for bankruptcy in 2020 after struggling to recruit patients willing to be tracked. (Some expressed privacy concerns. Others disliked the uncomfortable patch that received and forwarded the signal.)

More recent designs have been streamlined to ditch the patch, said etectRx senior vice president of operations Chris Carnes, PhD. And the cost of making a pill this kind of “smart” has come down to about a dollar.

So far, said Dr. Chai, in the patients he’s worked with, perceived benefits generally outweigh privacy concerns.

Studies are now underway in patients with heart disease and tuberculosis, and the company hopes to move into the aging and memory care space where medication-adherence is a serious problem.

“For us, or any company in this space, to succeed, you have to have a strong business case,” said Dr. Carnes. “If family members can keep their loved ones at home a little longer at an additional cost of $30 a month, that’s a no-brainer.”
 

Pillcams 2.0

Twenty-three years ago, the first video capsule endoscopy made it possible to image the small intestine via a tiny camera you swallow.

Such “pillcams” offered a more patient-friendly way to diagnose small bowel disorders, such as gastrointestinal bleeding and Crohn’s disease. Rather than undergoing sedation or anesthesia, as required during tube-based endoscopy, patients can go about their day as the pill painlessly passes through their gastrointestinal (GI) tract, capturing and recording data and images.

But the pills have their downsides.

Because they move passively, driven by movement in the intestine, they can miss trouble spots. Their ability to image the esophagus, stomach, and colon has proven limited. And unlike other procedures, like colonoscopy, they can’t intervene with therapy, like removing polyps.

The pillcam “had so much promise, to sort of revolutionize endoscopy, but it never really got the adoption that it seemed like it might,” said Andrew Meltzer, MD, professor of emergency medicine at the GW School of Medicine and Health Sciences in Washington.

That could soon change, he said, thanks to advances in locomotion and AI.

In a recent study of 40 patients, Dr. Meltzer tested a new magnetically controlled capsule endoscopy. Standing at a patient’s side, he could use a joystick to steer the pill around the stomach, capturing images in real time.

The pilot study, published in June 2023, found that the pill clearly identified six key stomach landmarks accurately 95% of the time and didn’t miss any lesions caught with traditional endoscopy. Notably, 80% of the patients preferred the pillcam over the tube.

“They are awake. They can go to work as soon as they leave. And it’s easy for them to tolerate,” Dr. Meltzer said.

More research is necessary, but Dr. Meltzer believes the technology could be particularly useful in the emergency department, allowing doctors to rule out high-risk bleeds in the stomach on the spot without admitting patients unnecessarily or making them return for a traditional scope.

“It has the potential to increase screening and provide more cost-effective care in emergencies,” he said.

It could also be useful in the telemedicine space, allowing a doctor to “drive” the pill from afar to diagnose a distant patient.

Someday, AI could enable the capsule to drive itself, so a doctor could merely press a button and wait. Or it could be adapted to treat what it finds, like administering a drug or cauterizing a bleed.

“If we can come up with a Mars rover which can explore other planets, we should be able to have something that can explore the stomach remotely,” Dr. Meltzer said.

Semaglutide improved metabolic dysfunction–associated steatotic liver disease (MASLD) among people living with HIV, and in some cases resolved it completely, according to results from the SLIM LIVER study presented by the AIDS Clinical Trials Group (ACTG) at this year’s Conference on Retroviruses and Opportunistic Infections (CROI) 2024 Annual Meeting in Denver.

Furthermore, although muscle volume decreased with weight loss, participants did not experience significant changes in muscle quality or physical function.
 

‘A First’

SLIM LIVER is the first study evaluating semaglutide as a treatment of MASLD among people living with HIV.

The phase 2b, single-arm pilot study enrolled adults living with HIV who were virally suppressed and had central adiposity, insulin resistance or prediabetes, and steatotic liver disease.

Participants self-injected semaglutide weekly at increasing doses until they reached a 1-mg dose at week 4. At 24 weeks, the study team assessed changes in participants’ intra-hepatic triglyceride content using magnetic resonance imaging-proton density fat fraction.

The primary analysis results from SLIM LIVER were reported in an oral presentation, “Semaglutide Reduces Metabolic-Associated Steatotic Liver Disease in People With HIV: The SLIM LIVER Study,” on March 5 by Jordan E. Lake, MD, MSc, of UTHealth Houston.

A subgroup analysis of the study was provided in a poster, “Effects of Semaglutide on Muscle Structure and Function in the SLIM LIVER Study,” presented on March 4 by Grace L. Ditzenberger, PT, DPT, of the University of Colorado Anschutz Medical Campus in Aurora.

In the primary analysis, the median age of the 49 participants was 52 years, 43% were women (cisgender and transgender), the mean body mass index was 35, 39% were Hispanic and 33% were Black/African American, and 82% were taking antiretroviral therapy that included an integrase inhibitor.

Liver fat was reduced by an average of 31%, with 29% of participants experiencing a complete resolution (5% or less liver fat) of MASLD. They also experienced weight loss, reduced fasting blood glucose, and reduced fasting triglycerides, consistent with effects observed in studies of semaglutide in people without HIV.

The sub-analysis of the 46 participants for whom muscle measurements were available showed that muscle volume (measured in the psoas) decreased but with no significant change in physical function.

Semaglutide was generally well tolerated, with an adverse event profile similar to that seen in individuals without HIV.

The most common adverse events were gastrointestinal (ie, nausea, diarrhea, vomiting, and abdominal pain). Two participants experienced more significant adverse events possibly related to semaglutide but were able to continue in the study.

All participants completed the full 24 weeks of therapy at the originally prescribed dose.
 

Potential Impact

“Even at the low dose of 1 mg every week, most participants lost significant weight, and weight loss was closely associated with improvements in MASLD,” Dr. Lake said. “Additional research will assess the secondary effects of semaglutide on systemic inflammation and metabolism and determine whether semaglutide may have unique risks or benefits for people living with HIV.”

“These findings have the potential to have a significant impact on the health and quality of life of people living with HIV,” added ACTG Chair Judith Currier, MD, MSc, University of California Los Angeles.

The SLIM LIVER study was sponsored by the US National Institute of Allergy and Infectious Diseases (NIAID), with additional funding from UTHealth Houston McGovern School of Medicine. ACTG is a clinical trials network focused on HIV and other infectious diseases, funded by NIAID and collaborating institutes of the US National Institutes of Health.

No conflicts of interest were reported.

TOPLINE:

A multicomponent strategy of nurse-led communication, home blood pressure monitoring, evidence-based treatment algorithms, and electronic health record tools improved systolic blood pressure (SBP) and non–high-density lipoprotein (non-HDL) cholesterol levels in people living with HIV.

METHODOLOGY:

• Investigators assessed if EXTRA-CVD, a nurse-led multicomponent intervention for preventing cardiovascular diseases (CVD), could effectively improve SBP and non-HDL cholesterol levels in people living with HIV whose viral replication has been controlled effectively using antiretroviral therapy.
• They recruited 297 individuals (median age, 59 years; 20.9% women) from three academic HIV clinics in the United States with an HIV-1 viral load < 200 copies/mL who were diagnosed with both hypertension and hypercholesterolemia.
• Participants were randomly assigned to either the EXTRA-CVD intervention group or a control group comprising individuals who received general prevention education.
• SBP (the primary outcome) was calculated as the mean of two SBP measurements obtained 1 minute apart, and non-HDL cholesterol (the secondary outcome) was calculated as total cholesterol minus HDL cholesterol.

TAKEAWAY:

• Participants in the intervention vs control group reported having significantly lower SBP as early as 4 months after the nurse-led strategy (mean difference, −6.4 mm Hg; P = .002), with the improvements sustaining until 12 months (mean difference, −4.2 mm Hg; P = .04).
• At 12 months, participants in the intervention group showed a 16.9-mg/dL (P < .001) reduction in non-HDL cholesterol levels compared with those in the control group.
• The nurse-led strategy led to a greater reduction in SBP in women with HIV vs men living with HIV (5.9 mm Hg greater SBP difference at 12 months), with the difference being clinically meaningful but not statistically significant.
• This nurse-led strategy did not increase the risk for adverse events in people living with HIV.

IN PRACTICE:

“Although the EXTRA-CVD intervention was limited to BP and cholesterol, nurse-led case management might be beneficial for a range of other primary care conditions in HIV clinics. If HIV clinics choose to implement EXTRA-CVD, they might consider adding staff trained in other chronic comorbidities and/or health promotion activities,” the authors noted.

TOPLINE:

A multicomponent strategy of nurse-led communication, home blood pressure monitoring, evidence-based treatment algorithms, and electronic health record tools improved systolic blood pressure (SBP) and non–high-density lipoprotein (non-HDL) cholesterol levels in people living with HIV.

METHODOLOGY:

• Investigators assessed if EXTRA-CVD, a nurse-led multicomponent intervention for preventing cardiovascular diseases (CVD), could effectively improve SBP and non-HDL cholesterol levels in people living with HIV whose viral replication has been controlled effectively using antiretroviral therapy.
• They recruited 297 individuals (median age, 59 years; 20.9% women) from three academic HIV clinics in the United States with an HIV-1 viral load < 200 copies/mL who were diagnosed with both hypertension and hypercholesterolemia.
• Participants were randomly assigned to either the EXTRA-CVD intervention group or a control group comprising individuals who received general prevention education.
• SBP (the primary outcome) was calculated as the mean of two SBP measurements obtained 1 minute apart, and non-HDL cholesterol (the secondary outcome) was calculated as total cholesterol minus HDL cholesterol.

TAKEAWAY:

• Participants in the intervention vs control group reported having significantly lower SBP as early as 4 months after the nurse-led strategy (mean difference, −6.4 mm Hg; P = .002), with the improvements sustaining until 12 months (mean difference, −4.2 mm Hg; P = .04).

When the world needed a COVID vaccine, leading HIV investigators answered the call to intervene in the coronavirus pandemic. Now, efforts to discover the world’s first HIV vaccine are revitalized.

“The body is capable of making antibodies to protect us from HIV,” says Yunda Huang, PhD, from the Fred Hutchinson Cancer Center in Seattle, Washington, who sat down with me before her talk today at the Conference on Retroviruses & Opportunistic Infections.

Dr. Huang spoke about the path forward for neutralizing antibody protection after the last attempt in a generation of HIV vaccine development ended in disappointment.

The past two decades marked the rise in HIV broadly neutralizing antibodies, with vaccine strategies to induce them. Promising advances include germline approaches, mRNA, and nanoparticle technologies.

The PrEP vaccine trial testing two experimental prevention regimens in Africa was stopped after investigators reported there is “little to no chance” the trial will show the vaccines are effective.
 

A Shape-Shifting Virus

HIV has been called the shape-shifting virus because it disguises itself so that even when people are able to make antibodies to it, the virus changes to escape.

But Dr. Huang and others are optimistic that an effective vaccine is still possible.

“We cannot and will not lose hope that the world will have an effective HIV vaccine that is accessible by all who need it, anywhere,” International AIDS Society (IAS) Executive Director Birgit Poniatowski said in a statement in December, when the trial was stopped.

HIV is a still persistent problem in the United States, according to the Centers for Disease Control and Prevention that reports it has affected an estimated 1.2 million people.

With new people infected every day around the globe, Dr. Huang says she feels a sense of urgency to help. “I think about all the people around the globe and the large number of young girls being hurt and I know our big pool of talent can intervene to change what we see happening.” 

Dr. Huang says the clinical trial failures we’ve seen so far will help guide next steps in HIV research as much as successes typically do.
 

Advances in the Field

With significant advances in protein nanoparticle science, mRNA technology, adjuvant development, and B-cell and antibody analyses, a new wave of clinical trials are on the way.

And with so many new approaches in the works, the HIV Vaccine Trials Network is retooling how it operates to navigate a burgeoning field and identify the most promising regimens.

A new Discovery Medicine Program will help the network assess new vaccine candidates. It will also aim to rule out others earlier on.

For COVID-19 and the flu, multimeric nanoparticles are an important alternative under investigation that could also be adapted for HIV.

Dr. Huang says she is particularly excited to watch the progress in cocktails of combination monoclonals. “I’ve been working in this field for 20 years now and there is a misconception that with pre-exposure prophylaxis, our job is done, but HIV is so far from away from being solved.”

But you just never know, Dr. Huang says. With new research, “we could bump on something at any point that changes everything.”

The smallpox vaccine effectively induces immunity against mpox virus infection (formerly simian smallpox) in patients with human immunodeficiency virus (HIV) infection, although patients with lymphocyte counts below 500 cells/mm³ require booster doses, according to data from a study published in the Journal of Medical Virology.

The data come from the prospective observational study conducted by researchers at the Infection Biology Laboratory of the Department of Medicine and Life Sciences at Pompeu Fabra University and the HIV Unit of the Hospital del Mar Medical Research Institute in Barcelona, Spain. The investigators analyzed T-cell responses induced by vaccination with JYNNEOS.

Despite the substantial decrease in the reporting frequency of mpox cases from the global peak in August 2022 (30,894 cases) to 804 monthly cases in the last six months of 2023, mpox continues to circulate, and there is no specific vaccine. The JYNNEOS vaccine, with protective cross-reactivity against orthopoxviruses, is approved by the US Food and Drug Administration and the European Medicines Agency for the prevention of smallpox and mpox in adults at high risk for infection.

During the 2022 outbreak in the United States and Europe, vaccine shortages led to the emergency use authorization of a lower intradermal dose. This strategy was aimed at increasing vaccine supply up to fivefold.

Further clinical trials are needed to evaluate responses to JYNNEOS vaccination and compare different administration routes in patients with HIV infection. Protecting this population against mpox is a priority because people with high viral loads or loCD4+ T-lymphocyte counts are especially susceptible to severe disease.
 

Vaccination Responses 

The study assessed the immune response to the JYNNEOS vaccine in patients with HIV who were receiving antiretroviral therapy as outpatients at the Infectious Diseases Unit of Hospital del Mar in Barcelona, Spain. Participants had viral loads controlled by antiretroviral therapy and CD4+ T-lymphocyte counts ≤ 500/mm³ (loCD4 group) or ≥ 500/mm³ (hiCD4 group) in blood. Vaccine responses were compared with those of vaccinated controls without the disease. The study included cases that received the standard subcutaneous vaccine (before August 2022) or the emergency dose-saving intradermal vaccine after its approval in August 2022.

The results demonstrated that the intradermal dose-saving vaccination route is preferable to the subcutaneous route and that patients in the loCD4 group may require at least one booster to generate an efficient response of specific T cells for mpox, wrote the authors.

“This study has two relevant points,” study author Robert Güerri-Fernandez, MD, PhD, head of infectious diseases at the Hospital del Mar Medical Research Institute, told this news organization. “In the subgroup of patients with HIV with effective treatment but without an immune response (ie, loCD4), the vaccine response is worse than in people who have recovered immunity or do not have HIV. Therefore, they need a booster dose.

“The second point is that the intradermal route with one-fifth of the standard subcutaneous dose has a better immune response than the standard subcutaneous route.” He added that it was a good strategy to save doses and be able to vaccinate many more people when vaccine shortages occurred.

“A general conclusion cannot be drawn,” he said. “It needs to be validated with many more subjects, of course, but in some way, it reinforced our confidence in the strategy of health authorities to promote intradermal vaccination. There we had evidence that the patients we were vaccinating intradermally were responding well.”

In Spain, although there is no shortage of vaccines today, they continue to be administered intradermally with a fractionated dose equivalent to one fifth of a standard dose, said Dr. Güerri-Fernandez.

However, in his opinion, observations regarding the two administration routes signal a need for further research. The main message should be that for patients with HIV infection who do not have an immune response, the vaccine response is incomplete, and they need booster doses as well as monitoring of the vaccine immune response, said Dr. Güerri-Fernandez.
 

More Studies Required

The research, which prospectively collected data and blood samples from patients with HIV who received the JYNNEOS vaccine, is small and included only 24 patients with HIV infection, with seven hospital workers who also received the vaccine and seven unvaccinated individuals as controls. “I am one of the control subjects of the study, and intradermal vaccination is not especially pleasant,” said Dr. Güerri-Fernandez. “It is a very innervated area, and the moment of introducing the liquid is uncomfortable. But it is perfectly bearable.”

Outpatient HIV-infected patients from the Infectious Diseases Unit of Hospital del Mar on antiretroviral therapy and with undetectable viral loads were grouped according to their CD4+ T-lymphocyte counts. Those with CD4+ T-lymphocyte counts ≤ 500/mm³ required at least one booster vaccine to exhibit efficient virus-specific T-lymphocyte responses. The magnitude of the T-cell response after this booster correlated directly with the CD4+ T-lymphocyte count of those vaccinated.

For Argentine infectious disease specialist Julián García, MD, clinical researcher at the Huésped Foundation in Buenos Aires, Argentina, who did not participate in the study, it is always productive to know that T-cell responses develop in patients with HIV infection, with CD4+ T-lymphocyte counts > and < 500/mm^3, through an intradermal administration route.

Dr. García emphasized that the most novel aspect is that the JYNNEOS vaccine induces a specific T-cell response in patients with HIV infection that increases with higher CD4+ T-lymphocyte levels. However, he noted that the number of patients was less than 10 in most study groups, and the control group had only intradermal administration, which limits the interpretation of the results. “It will be necessary to verify this in studies with larger groups with control groups from all routes and with a correlate of protection.”

Dr. García referred to this latter point as a significant source of uncertainty. “The study is fundamentally based on the cellular response, but nowadays, there is no immune correlate of real-life protection.” He concluded that the study builds knowledge, which is essential for a vaccine that began to be used for mpox and the effectiveness of which is based on estimates. 

Dr. Güerri-Fernandez and Dr. Garcia declared no relevant financial conflicts of interest.

For Argentine infectious disease specialist Julián García, MD, clinical researcher at the Huésped Foundation in Buenos Aires, Argentina, who did not participate in the study, it is always productive to know that T-cell responses develop in patients with HIV infection, with CD4+ T-lymphocyte counts > and < 500/mm^3, through an intradermal administration route.

Dr. García emphasized that the most novel aspect is that the JYNNEOS vaccine induces a specific T-cell response in patients with HIV infection that increases with higher CD4+ T-lymphocyte levels. However, he noted that the number of patients was less than 10 in most study groups, and the control group had only intradermal administration, which limits the interpretation of the results. “It will be necessary to verify this in studies with larger groups with control groups from all routes and with a correlate of protection.”

Dr. García referred to this latter point as a significant source of uncertainty. “The study is fundamentally based on the cellular response, but nowadays, there is no immune correlate of real-life protection.” He concluded that the study builds knowledge, which is essential for a vaccine that began to be used for mpox and the effectiveness of which is based on estimates. 

Dr. Güerri-Fernandez and Dr. Garcia declared no relevant financial conflicts of interest.

A new analysis supports using the smallpox antiviral tecovirimat (TPOXX/ST-246) in HIV patients showing the first symptoms of the human smallpox disease mpox (monkeypox), caused by the variola virus.

In a small prospective matched cohort analysis, people with HIV (PWH) and mpox disease who received tecovirimat within 7 days of symptom onset were 13 times less likely to experience progression, compared with PWH not prescribed tecovirimat within that window. In a matched cohort of 112 PWH, mpox disease progression occurred in 5.4% in an early tecovirimat group and in 26.8% in a late- or no-tecovirimat group, for a paired odds ratio of 13.00 (95% CI, 1.71-99.40; P = .002).

“Results of the present study suggest that tecovirimat treatment should be started early at the time of suspected mpox diagnosis in all PWH, especially in those with nonsuppressed HIV viremia or mucosal site involvement,” wrote a team led by Bruce Aldred, MD, of the Division of Infectious Diseases in the Department of Medicine at Emory University School of Medicine in Atlanta, in JAMA Internal Medicine. Early symptoms of mpox include skin rash and mucosal lesions, along with viral symptoms such as fever, headache, muscle aches, back pain, low energy, and swollen lymph nodes.

As of March 1 of last year, the United States reported more than 30,000 cases, while cases numbered more than 86,000 worldwide.

Despite a lack of effectiveness data in humans, tecovirimat was widely prescribed to PWH with mpox during the 2022 epidemic, which disproportionately affected PWH, particularly those with low CD4+ T-cell counts or severe mpox clinical manifestations who needed urgent therapy. Developed to treat smallpox, tecovirimat has antiviral activity against other orthopoxviruses, and has reduced mpox-related morbidity and mortality in animals.

Based on the animal data, approval was granted by the US Food and Drug Administration (FDA) for human mpox treatment. Dr. Aldred and colleagues undertook this cohort analysis in the absence of human data and with the postoutbreak decline in cases impeding recruitment to a full-scale clinical trial.

Study design

The preponderantly Black cohort included 112 PWH diagnosed with mpox at four Atlanta hospitals from June 1 to October 7, 2022. Patients were grouped in an early cohort receiving tecovirimat within 7 days of symptom onset or a no or late cohort (no tecovirimat or treatment more than 7 days after symptom onset. Multivariate logistic regression models identified factors associated with progression, defined as development of at least one severe CDC mpox criterion after symptom day 7.

The cohorts were then matched 1:1 using propensity scores based on the identified factors, and mpox disease progression was compared.

Of 112 PWH, 56 receive early tecovirimat and 56 received no or late treatment. In the early group, the median (interquartile range [IQR]) age was 35 (30-42) years; 54 individuals (96.4%) were cisgender men, 46 (82.1%) were Black, and 10 (17.9%) were, variously, White, American Indian, Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, or of unknown race.

In the late- or no-tecovirimat group, the median (IQR) age was 36 (32-43) years; 54 (96.4%) were cisgender men, 49 (87.5%) were Black, and 7 (12.5%) were individuals of other or unknown race. Mpox disease progression occurred in 3 PWH in the early-tecovirimat group and 15 PWH (26.8%) in the late- or no-tecovirimat group.

Dr. Aldred and colleagues acknowledged that more research is needed to confirm the findings and cited several study limitations. These included the small sample size, the preponderance of Black participants, and the possibility that unmatched confounding variables could have led to the observation of fewer cases of severe disease in the early-tecovirimat cohort.

This study was supported by a grant from the Emory Center for AIDS Research. Coauthors reported grants from various institutes at the National Institutes of Health as well as from multiple pharmaceutical companies.

The past year brought major changes in preventive standards for anxiety, HIV, and RSV along with new guidelines for the treatment of atrial fibrillation. For insight into the effect on internal medicine, we turned to Sarah Candler, MD, MPH, a Houston internist who specializes in the care of high-risk older adults.


Q: Which new prevention guidelines had the most impact on you over the past year?

A: I’m a primary care doctor, and most of the internal medicine updates that are interesting to me focus on how we can keep people from getting sick in the first place. That’s especially important in light of the fact that we had a decrease in life expectancy of 2 years [it finally rose slightly in 2022] and widening of the gender gap in life expectancy for men and women.

I’m excited to see new recommendations from the U.S. Preventive Services Task Force, including a new one about using PREP [pre-exposure prophylaxis] to preventively treat anyone who’s at risk for getting HIV. That’s a big one because it’s one of the first times that we’ve identified at-risk groups for screening based on social risk factors, not gender, age, or genetics.

The new recommendation is PREP for anyone who’s at risk for getting HIV because they have a partner with HIV, had an sexually transmitted infection in the last 6 months, or a history of inconsistent or no condom use with partners with unknown HIV status.

PREP therapy is something that most primary care physicians can either do or learn how to do pretty easily. But the treatment does require maintenance and monitoring.
 

Q: How firm is this recommendation?

A: The task force gives different grades for their recommendations based on how strong the evidence is. For the guidelines about PREP, they give a grade of A. That means this is top of the class: You should definitely do this.


Q: What are the best strategies to ask patients personal questions about their sex lives in order to evaluate their risk?

A: A lot of internal medicine physicians are getting pretty good at this. We see it as part of our job just the same way as we asked things like, “How often are you walking?” and “Have you been feeling down?”

There’s no one right way to have a conversation like that. But it’s key to say, as I do to my patients, that “I’m not here to judge anything. I am truly here to gather information and make recommendations to you as a partner in your care.”  
 

Q: What other guidelines made an impact in 2023?

A: The U.S. Preventive Services Task Force made a recommendation to screen adults aged 18-64 for anxiety, and this guidance got a B grade. [The task force said there’s not enough evidence to support routine anxiety screening in adults 65 and older.]

The new recommendations is a sign that we’re doing a better job at making treatment of those diseases more acceptable. This is also another example of the medical community recognizing that internal medicine physicians are pretty good at identifying and treating mental health.
 

Q: How do you figure out whether to treat depression/anxiety yourself or refer patients to specialists?

A: As a primary care physician, I feel comfortable diagnosing and managing some mental health disease in my own practice. There are FDA-approved medications for both anxiety and depression that are easily managed by a primary care physician.

And there’s something to the therapeutic relationship, to naming and identifying these conditions with your patients. Some patients feel a bit of relief just knowing that they have a diagnosis.
 

Q: What should internists know about the new CDC guidelines that promote discussing RSV vaccines with patients who are over 60?

A: The vaccines are recommended for folks who have underlying conditions like lung disease or heart disease. Those are the ones who end up getting really, really sick. There are two adult vaccines that are available, and there’s not a preference for one over the other.

The vaccines are both protein-based, like the old-school versions of vaccines, not the mRNA vaccines that we’ve all been hearing more about through COVID. Anybody who’s reluctant to take an mRNA vaccine can rest assured that the RSV is not protein-based. And they are single-dose vaccines, which is helpful.  
 

Q: What else should internists know about that was new in 2023?

A: I’m super excited about how cardiologists are thinking about atrial fibrillation. In 2023, the American College of Cardiology and the American Heart Association came up with a giant overhaul of how they look at atrial fibrillation. They classify it in stages and allows us to think about stopping it before it starts.

They’re talking about something they’re calling preclinical or subclinical atrial fibrillation, which you may detect on wearables like somebody’s watch or another tool used to monitor heart rate or exercise. It might be the first harbinger that there’s something wrong with the heart rate, and they may not even have symptoms of it. [A 2023 study in The New England Journal of Medicine linked the anticoagulant apixaban, or Eliquis, to a 37% lower risk of stroke and systemic embolism rates in older patients with subclinical atrial fibrillation but an 80% higher risk of major bleeding vs. aspirin therapy.]

And they’re now recommending early rhythm control.
 

Q: What does early rhythm control mean for patients and physicians?

A: For the longest time, we have thought about atrial fibrillation treatment in terms of rate control and not worrying too much about the rhythm. But now we recognize that it’s actually really important that we get the rhythm under control because physical changes to the heart can lead to permanent damage.

So now they’re recommending catheter ablation as first-line therapy in some patients as a class 1 recommendation because heart function is already decreased. Improving the ability of the heart to beat with a regular rhythm can lead to improvement of function. This was unheard of even 5 years ago.
 

Q: Should internists be more willing to refer patients with atrial fibrillation to cardiologists?

A: Yes, I think so. One of the biggest changes for me is that I am going to refer new diagnoses of atrial fibrillation to a cardiologist. And I’m going to ask patients if they have wearable devices because sometimes those things might tell me about something like subclinical atrial fibrillation.

Q: There’s also detailed data about atrial fibrillation risk factors, which include older age, smoking, sedentary lifestyle, alcohol use, diabetes, height, obesity, diabetes, and others. Is this information useful?

A: It’s a really great tool to have in the arsenal because it helps me have shared decision-making conversations with my patients in a way that’s much more convincing. A patient might say, “Why do you care if I drink so much? My liver levels are fine.” And I can say, “It’s going to be a risk factor for having problems with your heart.”

For better or worse, people really take the heart very seriously, I am an internal medicine physician, so I love all the organs equally. But man, people get pretty scared when you tell them something can affect their heart. So when I talk to patients about their risk factors, it’s going to really be helpful that I can remind them of the impact that some of these lifestyle behaviors can have on their heart health.

Q: There’s also detailed data about atrial fibrillation risk factors, which include older age, smoking, sedentary lifestyle, alcohol use, diabetes, height, obesity, diabetes, and others. Is this information useful?

A: It’s a really great tool to have in the arsenal because it helps me have shared decision-making conversations with my patients in a way that’s much more convincing. A patient might say, “Why do you care if I drink so much? My liver levels are fine.” And I can say, “It’s going to be a risk factor for having problems with your heart.”

For better or worse, people really take the heart very seriously, I am an internal medicine physician, so I love all the organs equally. But man, people get pretty scared when you tell them something can affect their heart. So when I talk to patients about their risk factors, it’s going to really be helpful that I can remind them of the impact that some of these lifestyle behaviors can have on their heart health.

A class action lawsuit against Mass General Brigham, Salem Hospital, and 10 unnamed employees has been filed after at least 450 patients were notified of their possible exposure to HIV and hepatitis.

The negligent administration of intravenous medications during endoscopy procedures performed between June 14, 2021, and April 19, 2023, at Salem Hospital, located about 20 miles northeast of Boston, has caused a “heightened risk of exposure to these harmful life-altering and life-threatening infections,” according to the lawsuit filed at Suffolk County Superior Court in Boston by Keches Law Group on behalf of plaintiff Melinda Cashman and others.

Although patients were notified in early November of their potential exposure, it could take months or even years to determine if infection has occurred. Attorneys for Ms. Cashman claim that the plaintiff “suffered and will continue to suffer severe emotional distress and anguish” as a result of the associated risks.

The lawyers argue that Ms. Cashman and others like her may “suffer permanent injuries,” along with “extreme anxiety and decreased quality of life.” They are seeking monetary damages to offset disruptions to relationships, increased medical bills, and any mental health therapy required.

Outreach to potentially affected patients began after the hospital was made aware, earlier this year, of an “isolated practice” that could have led to viral transmission, according to a statement from Mass General Brigham, but there is no evidence to date of any infections resulting from this incident. “We sincerely apologize to those who have been impacted and we remain committed to delivering high-quality, compassionate healthcare to our community.”

Hepatitis B and C are both treatable with antiviral mediations, and hepatitis C is curable in 95% of cases, according to the Centers for Disease Control and Prevention. HIV, although not curable, can be managed with antiretroviral therapy.

Mass General Brigham is working with the Massachusetts Department of Public Health, which will conduct an onsite investigation into quality-control practices. Affected patients can reach out to a clinician-staffed hotline with questions and receive free screening for the viruses, hospital officials report.
