Differences in metabolism of levodopa between patients with Parkinson’s disease may be caused by variations in gut bacteria, according to investigators.

Specifically, patients with a higher abundance of Enterococcus faecalis may be converting levodopa into dopamine via decarboxylation before it can cross the blood-brain barrier, reported Emily P. Balskus, PhD, of Harvard University in Cambridge, Mass.

Although existing decarboxylase inhibitors, such as carbidopa, can reduce metabolism of levodopa by host enzymes, these drugs are unable to inhibit the enzymatic activity of E. faecalis in the gut, Dr. Balskus said at the annual Gut Microbiota for Health World Summit, sponsored by the American Gastroenterological Association and the European Society for Neurogastroenterology and Motility.

“[Carbidopa] is actually completely ineffective at inhibiting decarboxylation in human fecal suspension,” Dr. Balskus said, referring to research led by PhD student Vayu Maini Rekdal. “We think that this could indicate that patients who are taking carbidopa are not inhibiting any bacterial metabolism that they may have.”

While previous research showed that E. faecalis could decarboxylate levodopa, Dr. Balskus and colleagues linked this process with the tyrosine decarboxylase gene (TyrDC), and showed that the of abundance E. faecalis and TyrDC correlate with levodopa metabolism.

Unlike the human enzyme responsible for decarboxylation of levodopa, the E. faecalis enzyme preferentially binds with L-tyrosine. This could explain why existing decarboxylase inhibitors have little impact on decarboxylation in the gut, Dr. Balskus said.

She also noted that this unique characteristic may open doors to new therapeutics. In the lab, Dr. Balskus and colleagues tested a decarboxylase inhibitor that resembled L-tyrosine, (S)-alpha-fluoromethyltyrosine (AFMT). Indeed, AFMT completely inhibited of decarboxylation of levodopa in both E. faecalis cells and complex human microbiome samples.

“We think this is pretty exciting,” Dr. Balskus said.

Early animal studies support this enthusiasm, as germ-free mice colonized with E. faecalis maintain higher serum levels of levodopa with concurrent administration of AFMT.

“We think that this could indicate that a promising way to improve levodopa therapy for Parkinson’s patients would be to develop compounds that inhibit bacterial drug metabolism activity,” Dr. Balskus said.

Concluding her presentation, Dr. Balskus emphasized the importance of a biochemical approach to microbiome research. “Studying enzymes opens up new, exciting opportunities for microbiome manipulation. We can design or develop inhibitors of enzymes, use those inhibitors as tools to study the roles of individual metabolic activities, and potentially use them as therapeutics. We are very excited about the possibility of treating or preventing human disease not just by manipulating processes in our own cells, but by targeting activities in the microbiota.”

LAHAINA, HAWAII – Reassuring evidence of the safety of oral propranolol for treatment of complicated infantile hemangiomas in patients with PHACE syndrome comes from a recent multicenter study.

Bruce Jancin/MDedge News

Oral propranolol is now well-ensconced as first-line therapy for complicated infantile hemangiomas in otherwise healthy children. However, the beta-blocker’s use in PHACE (Posterior fossa malformations, Hemangiomas, Arterial anomalies, Cardiac defects, and Eye abnormalities) syndrome has been controversial, with concerns raised by some that it might raise the risk for arterial ischemic stroke. Not so, Moise L. Levy, MD, said at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation.

“I’m not suggesting you use propranolol with reckless abandon in this population, but this stroke concern is something that should be put to bed based on this study,” advised Dr. Levy, professor of dermatology and pediatrics at Dell Medical School in Austin, Tex., and physician-in-chief at Dell Children’s Medical Center.

PHACE syndrome is characterized by large, thick, plaque-like hemangiomas greater than 5 cm in size, most commonly on the face, although they can be located elsewhere.

“There was concern that if you found severely altered cerebrovascular arterial flow and you put a kid on a beta-blocker you might be causing some harm. But what I will tell you is that in this recently published paper this was not in fact an issue,” he said.

Dr. Levy was not an investigator in the multicenter retrospective study, which included 76 patients with PHACE syndrome treated for infantile hemangioma with oral propranolol at 0.3 mg/kg per dose or more at 11 academic tertiary care pediatric dermatology clinics. Treatment started at a median age of 56 days.

There were no strokes, TIAs, cardiovascular events, or other significant problems associated with treatment. Twenty-nine children experienced mild adverse events: minor gastrointestinal or respiratory symptoms, and sleep disturbances were threefold more frequent than reported with placebo in another study. The investigators noted that the safety experience in their PHACE syndrome population compared favorably with that in 726 infants without PHACE syndrome who received oral propranolol for hemangiomas, where the incidence of serious adverse events on treatment was 0.4% (JAMA Dermatol. 2019 Dec 11. doi: 10.1001/jamadermatol.2019.3839).

 

‘Hemangiomas – but we were taught that they go away’

Dr. Levy gave a shout-out to the American Academy of Pediatrics for publishing interdisciplinary expert consensus-based practice guidelines for the management of infantile hemangiomas, which he praised as “quite well done” (Pediatrics. 2019 Jan;143[1]. pii: e20183475. doi: 10.1542/peds.2018-3475).

Following release of the guidelines last year, he and other pediatric vascular anomalies experts saw an uptick in referrals from general pediatricians, which has since tapered off.

“It’s probably like for all of us: We read an article, it’s fresh on the mind, then you forget about the article and what you’ve read. So we need a little reinforcement from a learning perspective. This is a great article,” he said.

The guidelines debunk as myth the classic teaching that infantile hemangiomas go away. Explicit information is provided about the high-risk anatomic sites warranting consideration for early referral, including the periocular, lumbosacral, and perineal areas, the lip, and lower face.

“The major point is early identification of those lesions requiring evaluation and intervention. Hemangiomas generally speaking are at their ultimate size by 3-5 months of age. The bottom line is if you think something needs to be done, please send that patient, or act upon that patient, sooner rather than later. I can’t tell you how many cases of hemangiomas I’ve seen when the kid is 18 months of age, 3 years of age, 5 years, with a large area of redundant skin, scarring, or something of that sort, and it would have been really nice to have seen them earlier and acted upon them then,” the pediatric dermatologist said.

The guidelines recommend intervention or referral by 1 month of age, ideally. Guidance is provided about the use of oral propranolol as first-line therapy.

“Propranolol is something that has been a real game changer for us,” he noted. “Many people continue to be worried about side effects in using this, particularly in the young childhood population, but this paper shows pretty clearly that hypotension or bradycardia is not a real concern. I never hospitalize these patients for propranolol therapy except in high-risk populations: very preemie, any history of breathing problems. We check the blood pressure and heart rate at baseline, again at 7-10 days, and at every visit. We’ve never found any significant drop in blood pressure.”

Dr. Levy reported financial relationships with half a dozen pharmaceutical companies, none relevant to his presentation.

LAHAINA, HAWAII – The rash commonly called perioral dermatitis is more appropriately termed periorificial dermatitis, according to Jessica Sprague, MD, a pediatric dermatologist at the University of California, San Diego, and Rady Children’s Hospital.

Bruce Jancin/MDedge News

Years ago, some of her senior colleagues at the children’s hospital carried out a retrospective study of 79 patients, aged 6 months to 18 years, who were treated for what’s typically called perioral dermatitis. Of note, only 40% of patients had isolated perioral involvement, while 30% of the patients had no perioral lesions at all. Perinasal lesions were present in 43%, and 25% had periocular involvement, she noted at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation.

The peak incidence of periorificial dermatitis in this series was under age 5 years. At presentation, the rash had been present for an average of 8 months. Seventy-two percent of patients had a history of exposure to corticosteroids, most often in the form of topical steroids, but in some cases inhaled or systemic steroids.

“Obviously you want to discontinue the topical steroid. Sometimes you need to taper them off, or you can switch to a topical calcineurin inhibitor [TCI] because they tend to flare a lot when you stop their topical steroid, although there are cases of TCIs precipitating periorificial dermatitis, so keep that in mind,” Dr. Sprague said.

If a patient is on inhaled steroids by mask for asthma, switching to a tube can sometimes limit the exposure, she continued.

MAUI, HAWAII – Viewing seronegative rheumatoid arthritis as something akin to RA-lite would be a big mistake, John J. Cush, MD, asserted at the 2020 Rheumatology Winter Clinical Symposium.

Bruce Jancin/MDedge News

“It’s not a benign subtype of RA. And then again, it may not be RA,” Dr. Cush observed,

“Seronegative RA means that either you need to get serious about what is probably badass disease or you need to reevaluate whether this really is RA and your need for DMARDs [disease-modifying antirheumatic drugs] in an ongoing fashion,” the rheumatologist said. “Always reconsider whether they need less therapy or maybe no therapy at all. Maybe they had inflammation at one point and now they’re left with degenerative and mechanical changes that don’t require a DMARD or biologic.”

He highlighted a Finnish 10-year, prospective, observational study that sheds light on the subject. The study demonstrated that seronegative RA is seldom what it at first seems. The Finnish rheumatologists followed 435 consecutive patients initially diagnosed as having seronegative early RA. The structured follow-up entailed four or five interdisciplinary clinic visits within the first 2 years after diagnosis and again at 5 and 10 years.

By the 10-year mark only 4 of the 435 initially seronegative RA patients had been reclassified as having seropositive RA, while another 9 were reclassified as having erosive RA based upon the development of pathognomonic joint lesions. That’s a paltry 3% reclassification rate to classic RA.

Nearly two-thirds of patients were ultimately reclassified within 10 years as they evolved into diagnoses other than their original seronegative RA. The most common included nonerosive polymyalgia rheumatica in 16% of participants, psoriatic arthritis in 11%, osteoarthritis in 10%, spondyloarthritis in 8.7%, gout in 2.3%, and pseudogout in 3.9%.

“I think that’s sobering for you if you’re taking care of these patients, that maybe you need to rethink the diagnosis at every visit or at periodic intervals, especially if you’re going to change therapy,” advised Dr. Cush, who is professor of medicine and rheumatology at Baylor University Medical Center, Dallas, and director of clinical rheumatology at the Baylor Research Institute.

The Finnish rheumatologists observed that their findings have important implications both for clinical practice and for research, since RA clinical trials typically include a substantial proportion of seronegative patients.

“If seronegative patients are treated according to the treatment guidelines for progressive RA, a substantial proportion of patients is exposed to unnecessary long-term medication,” the investigators wrote, adding that their “results suggest that it may not be reasonable to study seronegative arthritis patients as a homogeneous entity in RA studies.”

The best recent data suggests about 15% of RA patients are seronegative, Dr. Cush said.

Delay in diagnosis is common in seronegative RA, as highlighted in a recent population-based study by Mayo Clinic rheumatologists. They reported that the median time from first joint swelling to diagnosis of seronegative RA using the 2010 American College of Rheumatology/European League Against Rheumatism criteria was 187 days, compared with a mere 11 days for seropositive RA. The median time to DMARD initiation was longer, too. Half of seropositive RA patients achieved remission within 5 years, as did 28% of seronegative patients, prompting the investigators to conclude “the window of opportunity for intervention may be more frequently missed in this group.”
 

Choosing the best treatment

Several medications appear to have greater efficacy in seropositive than seronegative RA patients. For example, a meta-analysis of four randomized trials including a collective 2,177 RA patients assigned 2:1 to rituximab (Rituxan) or placebo concluded that 75% of seropositive RA patients had a EULAR moderate or good response at week 24 on the biologic, compared with 44% of seronegative patients.

“Would you not use rituximab in someone who’s seronegative? No, I actually would use it. I may not rush to use it as much, maybe give it earlier in someone who’s seropositive, but I’ve used rituximab in seronegative patients who’ve done just fine,” according to Dr. Cush.

The published experience with abatacept (Orencia) is mixed, most of it coming from European observational datasets. On balance though, 80% of the articles addressing the issue have concluded that response rates to the biologic are better in seropositive RA, he continued.

Australian investigators who pooled data from five phase 3 randomized clinical trials of tofacitinib (Xeljanz) in RA concluded that double-positive patients – that is, those who were seropositive for both rheumatoid factor and anti–citrullinated protein antibody (ACPA) – were roughly twice as likely to achieve ACR20 and ACR50 responses to the oral Janus kinase inhibitor at either 5 or 10 mg twice daily than patients who were double negative.

“Double positivity is very important in prognosis and severity, compared to single positivity,” the rheumatologist observed. “I think you should worry most about the patients who have the highest titers of rheumatoid factor and ACPA.”

Asked about the merits of supplemental laboratory testing for serum 14-3-3 eta, a proposed novel biomarker in RA, as well as for anti–carbamylated protein antibodies (anti-CarP), Dr. Cush replied that it’s unclear that the additional testing is really worthwhile.

“Ordering more tests doesn’t make us smarter,” he commented. “Quite simply, with rheumatoid factor and ACPA, adding one on top of the other, you just gain maybe 10% more certainty in the diagnosis. Adding anti-CarP antibodies or serum 14-3-3 eta doesn’t add more than a few percentage points, but now you’ve quadrupled the cost of testing.”

MAUI, HAWAII – Viewing seronegative rheumatoid arthritis as something akin to RA-lite would be a big mistake, John J. Cush, MD, asserted at the 2020 Rheumatology Winter Clinical Symposium.

“It’s not a benign subtype of RA. And then again, it may not be RA,” Dr. Cush observed,

“Seronegative RA means that either you need to get serious about what is probably badass disease or you need to reevaluate whether this really is RA and your need for DMARDs [disease-modifying antirheumatic drugs] in an ongoing fashion,” the rheumatologist said. “Always reconsider whether they need less therapy or maybe no therapy at all. Maybe they had inflammation at one point and now they’re left with degenerative and mechanical changes that don’t require a DMARD or biologic.”

He highlighted a Finnish 10-year, prospective, observational study that sheds light on the subject. The study demonstrated that seronegative RA is seldom what it at first seems. The Finnish rheumatologists followed 435 consecutive patients initially diagnosed as having seronegative early RA. The structured follow-up entailed four or five interdisciplinary clinic visits within the first 2 years after diagnosis and again at 5 and 10 years.

By the 10-year mark only 4 of the 435 initially seronegative RA patients had been reclassified as having seropositive RA, while another 9 were reclassified as having erosive RA based upon the development of pathognomonic joint lesions. That’s a paltry 3% reclassification rate to classic RA.

Nearly two-thirds of patients were ultimately reclassified within 10 years as they evolved into diagnoses other than their original seronegative RA. The most common included nonerosive polymyalgia rheumatica in 16% of participants, psoriatic arthritis in 11%, osteoarthritis in 10%, spondyloarthritis in 8.7%, gout in 2.3%, and pseudogout in 3.9%.

“I think that’s sobering for you if you’re taking care of these patients, that maybe you need to rethink the diagnosis at every visit or at periodic intervals, especially if you’re going to change therapy,” advised Dr. Cush, who is professor of medicine and rheumatology at Baylor University Medical Center, Dallas, and director of clinical rheumatology at the Baylor Research Institute.

The Finnish rheumatologists observed that their findings have important implications both for clinical practice and for research, since RA clinical trials typically include a substantial proportion of seronegative patients.

“If seronegative patients are treated according to the treatment guidelines for progressive RA, a substantial proportion of patients is exposed to unnecessary long-term medication,” the investigators wrote, adding that their “results suggest that it may not be reasonable to study seronegative arthritis patients as a homogeneous entity in RA studies.”

The best recent data suggests about 15% of RA patients are seronegative, Dr. Cush said.

Delay in diagnosis is common in seronegative RA, as highlighted in a recent population-based study by Mayo Clinic rheumatologists. They reported that the median time from first joint swelling to diagnosis of seronegative RA using the 2010 American College of Rheumatology/European League Against Rheumatism criteria was 187 days, compared with a mere 11 days for seropositive RA. The median time to DMARD initiation was longer, too. Half of seropositive RA patients achieved remission within 5 years, as did 28% of seronegative patients, prompting the investigators to conclude “the window of opportunity for intervention may be more frequently missed in this group.”
 

Choosing the best treatment

Several medications appear to have greater efficacy in seropositive than seronegative RA patients. For example, a meta-analysis of four randomized trials including a collective 2,177 RA patients assigned 2:1 to rituximab (Rituxan) or placebo concluded that 75% of seropositive RA patients had a EULAR moderate or good response at week 24 on the biologic, compared with 44% of seronegative patients.

“Would you not use rituximab in someone who’s seronegative? No, I actually would use it. I may not rush to use it as much, maybe give it earlier in someone who’s seropositive, but I’ve used rituximab in seronegative patients who’ve done just fine,” according to Dr. Cush.

The published experience with abatacept (Orencia) is mixed, most of it coming from European observational datasets. On balance though, 80% of the articles addressing the issue have concluded that response rates to the biologic are better in seropositive RA, he continued.

Australian investigators who pooled data from five phase 3 randomized clinical trials of tofacitinib (Xeljanz) in RA concluded that double-positive patients – that is, those who were seropositive for both rheumatoid factor and anti–citrullinated protein antibody (ACPA) – were roughly twice as likely to achieve ACR20 and ACR50 responses to the oral Janus kinase inhibitor at either 5 or 10 mg twice daily than patients who were double negative.

“Double positivity is very important in prognosis and severity, compared to single positivity,” the rheumatologist observed. “I think you should worry most about the patients who have the highest titers of rheumatoid factor and ACPA.”

Asked about the merits of supplemental laboratory testing for serum 14-3-3 eta, a proposed novel biomarker in RA, as well as for anti–carbamylated protein antibodies (anti-CarP), Dr. Cush replied that it’s unclear that the additional testing is really worthwhile.

“Ordering more tests doesn’t make us smarter,” he commented. “Quite simply, with rheumatoid factor and ACPA, adding one on top of the other, you just gain maybe 10% more certainty in the diagnosis. Adding anti-CarP antibodies or serum 14-3-3 eta doesn’t add more than a few percentage points, but now you’ve quadrupled the cost of testing.”

The single-tablet antiretroviral regimen of bictegravir, emtricitabine, and tenofovir alafenamide (B/F/TAF) was assessed as being noninferior to two dolutegravir (DTG)-containing regimens among adults aged 50 and over living with HIV, according to a new study.

The study pooled data from two phase 3, randomized, double-blind B/F/TAF studies comparing that regimen with DTG-containing regimens for adults living with HIV who were treatment naive. Anthony Mills, MD, a physician in private practice in West Hollywood, Calif., and his associates reported results at the 144-week mark for the two studies in a poster that was presented as part of the Conference on Retroviruses & Opportunistic Infections, which was presented online this year. CROI organizers chose to hold a virtual meeting because of concerns about the spread of COVID-19.

In the two trials, the B/F/TAF regimen was compared with a DTG and abacavir/lamivudine (DTG + ABC/3TC) regimen, as well as with DTG plus emtricitabine/tenofovir alafenamide (DTG + F/TAF). A total of 629 patients were enrolled in the first study, and 645 in the second. Of these, a total of 196 patients were aged 50 years or older. Across all study arms, most participants (73%-92%) were male, and 20%-37% were black or of African descent. Participants identifying as Hispanic or being of Latino ancestry made up 11%-27% of participants.

About 80%-90% of patients had asymptomatic HIV infection at the time of enrollment, with median CD4 counts ranging from 405-534 cells/mcL across study arms. Patients had a median 4.27-4.53 log (base 10) copies/mL at baseline. In both studies, patients had to have at least 500 HIV-1 RNA copies per mL, and couldn’t have known resistance to any of the study drugs.

At week 144, there were no statistically significant differences in virologic outcomes across study arms in the younger or older age subgroups: 81% of the B/F/TAF patients older than 50 years had fewer than 50 copies/mL of HIV-1 RNA, compared with 83% and 88% of the younger DTG/ABC/3TC and DTG + F/TAF groups meeting this mark, respectively.

Results were similar for the patients aged younger than 50 years, with 82%, 84%, and 83% of the B/F/TAF, DTG/ABC/3TC, and DTG + F/TAF groups having fewer than 50 copies/mL of HIV-1 RNA, respectively.

No patients in either age group showed resistance to any components of the treatment regimens. No treatment-emergent resistance was seen in any study participants, and few adverse events occurred. Those that were seen didn’t occur more frequently in older patients, compared with younger patients, and no patients discontinued their treatment because of renal issues.

Bone mineral density (BMD) was only measured in the study that compared B/F/TAF with DTG/ABC/3TC. Hip BMD decreased slightly in both groups, but the changes were comparable between older and younger participants. For both age groups, differences weren’t significant between the B/F/TAF group and those taking DTG/ABC/3TC. Spine density actually increased slightly in older patients taking B/F/TAF, but the difference between this measure and the slight decrease in older patients taking DTG/ABC/3TC was not significant.

Weight increased over time for all groups, ranging from a gain of 3.4 kg at 144 weeks for older patients taking DTG + F/TAF to 5.3 kg for the same regimen in younger patients, but none of the between-group differences were significant.

All fasting lipids rose for each study arm in both older and younger patients. Some of the between-group differences were statistically significant, but “there were no clinically significant differences in median changes from baseline in fasting lipids” among those aged 50 years or older, noted Dr. Mills and associates.

In terms of safety, no study drug-related discontinuations for renal adverse events occurred in either the B/F/TAF or the DTG + F/TAF groups, and the investigators saw no proximal renal tubulopathy.

The estimated glomerular filtration rate (eGFR) was calculated using the Cockroft-Gault equation. All three antiviral regimens were associated with early drops in eGFR, “consistent with inhibition of tubular creatinine secretion via organic cation transporter 2,” noted Dr. Mills and associates.

Other adverse events were rare in all groups in both older and younger patients, without significant differences between therapies.

The study was supported by Gilead Sciences, which also provided support to Dr. Mills. One coauthor is a Gilead employee.

Despite highly effective antiretroviral therapy, HIV still shortens life expectancy by 9 years and healthy life expectancy free of comorbidities 16 years, according to a review of HIV patients and matched controls at Kaiser Permanente facilities in California and the mid-Atlantic states during 2000-2016.

M. Alexander Otto/MDedge News

The good news is that starting antiretroviral therapy (ART) when CD4 counts are 500 cells/mm³ or higher closes the mortality gap. People who do so can expect to live into their mid-80s, the same as people without HIV, and the years they can expect to be free of diabetes and cancer is catching up to uninfected people, although the gap for other comorbidities hasn’t changed and the overall comorbidity gap remains 16 years, according to the report, which was presented at the Conference on Retroviruses & Opportunistic Infections

“We were excited about finding no difference in lifespan for people starting ART with high CD4 counts, but we were surprised by how wide the gap was for the number of comorbidity free years. Greater attention to comorbidity prevention is needed,” said study lead Julia Marcus, PhD, an infectious disease epidemiologist and assistant professor of population medicine at Harvard Medical School, Boston.

The team estimated the average number of total and comorbidity-free years of life remaining at age 21 for 39,000 people with HIV who were matched 1:10 with 387,767 uninfected adults by sex, race/ethnicity, year, and medical center.

Overall, adults with HIV could expect to live until they were 77 years old, versus 86 years for people without HIV, during 2014-2016. It’s a large improvement over the 22 year gap during 2000-2003, when the numbers were 59 versus 81 years, respectively, Dr. Marcus reported at the virtual meeting, which was scheduled to be in Boston, but held online this year because of concerns about spreading the COVID-19 virus.

But the overall comorbidity gap didn’t budge during 2000-2016. People with HIV during 2014-2016 could expect to be comorbidity free until age 36 years, versus 52 years for the general population, the same 16-year difference during 2000-2003, when the numbers were age 32 versus age 48 years.

During 2014-2016, liver disease came 24 years sooner with HIV, and chronic kidney disease 17 years, chronic lung disease 16 years, cancer 9 years, and diabetes and cancer both 8 years sooner. Early ART didn’t narrow the gap for most comorbidities. Dr. Marcus didn’t address the reasons for the differences, except to note that “smoking rates were definitely higher among people with HIV.”

The results weren’t broken down by sex, but the majority of subjects, 88%, were men. The mean age was 41 years, and about half were white, with most of the rest either black or Hispanic. Transmission was among men who have sex with men in 70% of the cases, heterosexual sex in 20%, and IV drug accounted for the rest. Almost a third of the subjects started ART with CD4 counts at or above 500 cells/mm³.

Dr. Marcus said the results are likely generalizable to most insured people with HIV, but also that comorbidity screening might be higher in the HIV population, which could have affected the results.

The work was funded by the National Institutes of Health. Dr. Marcus is an adviser for Gilead.

People who do so can expect to live into their mid-80s, the same as people without HIV, and the years they can expect to be free of diabetes and cancer is catching up to uninfected people, although the gap for other comorbidities hasn’t changed and the overall comorbidity gap remains 16 years, according to the report, which was presented at the Conference on Retroviruses & Opportunistic Infections

“We were excited about finding no difference in lifespan for people starting ART with high CD4 counts, but we were surprised by how wide the gap was for the number of comorbidity free years. Greater attention to comorbidity prevention is needed,” said study lead Julia Marcus, PhD, an infectious disease epidemiologist and assistant professor of population medicine at Harvard Medical School, Boston.

The team estimated the average number of total and comorbidity-free years of life remaining at age 21 for 39,000 people with HIV who were matched 1:10 with 387,767 uninfected adults by sex, race/ethnicity, year, and medical center.

Overall, adults with HIV could expect to live until they were 77 years old, versus 86 years for people without HIV, during 2014-2016. It’s a large improvement over the 22 year gap during 2000-2003, when the numbers were 59 versus 81 years, respectively, Dr. Marcus reported at the virtual meeting, which was scheduled to be in Boston, but held online this year because of concerns about spreading the COVID-19 virus.

But the overall comorbidity gap didn’t budge during 2000-2016. People with HIV during 2014-2016 could expect to be comorbidity free until age 36 years, versus 52 years for the general population, the same 16-year difference during 2000-2003, when the numbers were age 32 versus age 48 years.

During 2014-2016, liver disease came 24 years sooner with HIV, and chronic kidney disease 17 years, chronic lung disease 16 years, cancer 9 years, and diabetes and cancer both 8 years sooner. Early ART didn’t narrow the gap for most comorbidities. Dr. Marcus didn’t address the reasons for the differences, except to note that “smoking rates were definitely higher among people with HIV.”

The results weren’t broken down by sex, but the majority of subjects, 88%, were men. The mean age was 41 years, and about half were white, with most of the rest either black or Hispanic. Transmission was among men who have sex with men in 70% of the cases, heterosexual sex in 20%, and IV drug accounted for the rest. Almost a third of the subjects started ART with CD4 counts at or above 500 cells/mm³.

Dr. Marcus said the results are likely generalizable to most insured people with HIV, but also that comorbidity screening might be higher in the HIV population, which could have affected the results.

The work was funded by the National Institutes of Health. Dr. Marcus is an adviser for Gilead.

At the end of 6 months of low-dose pomalidomide (Pomalyst), more than half of men who have sex with men had partial or complete clearance of long-standing, grade 3 anal lesions from human papillomavirus, irrespective of HIV status; the number increased to almost two-thirds when they were checked at 12 months, according to a 26-subject study said in video presentation of his research during the Conference on Retroviruses & Opportunistic Infections, which was presented online this year. CROI organizers chose to hold a virtual meeting because of concerns about the spread of COVID-19.

“Therapy induced durable and continuous clearance of anal HSIL [high-grade squamous intraepithelial lesions]. Further study in HPV-associated premalignancy is warranted to follow up this small, single arm study,” said study lead Mark Polizzotto, MD, PhD, head of the therapeutic and vaccine research program at the Kirby Institute in Sydney.

HPV anal lesions, and subsequent HSIL and progression to anal cancer, are prevalent among men who have sex with men. The risk increases with chronic lesions and concomitant HIV infection.

Pomalidomide is potentially a less painful alternative to options such as freezing and laser ablation, and it may have a lower rate of recurrence, but it’s expensive. Copays range upward from $5,000 for a month supply, according to GoodRx. Celgene, the maker of the drug, offers financial assistance.

Pomalidomide is a derivative of thalidomide that’s approved for multiple myeloma and also has shown effect against a viral lesion associated with HIV, Kaposi sarcoma. The drug is a T-cell activator, and since T-cell activation also is key to spontaneous anal HSIL clearance, Dr. Polizzotto and team wanted to take a look to see if it could help, he said.

The men in the study were at high risk for progression to anal cancer. With a median lesion duration of more than 3 years, and at least one case out past 7 years, spontaneous clearance wasn’t in the cards. The lesions were all grade 3 HSIL, which means severe dysplasia, and more than half of the subjects had HPV genotype 16, and the rest had other risky genotypes. Ten subjects also had HIV, which also increases the risk of anal cancer.

Pomalidomide was given in back-to-back cycles for 6 months, each consisting of 2 mg orally for 3 weeks, then 1 week off, along with a thrombolytic, usually aspirin, given the black box warning of blood clots. The dose was half the 5-mg cycle for Kaposi’s.

The overall response rate – complete clearance or a partial clearance of at least a 50% on high-resolution anoscopy – was 50% at 6 months (12/24), including four complete responses (4/15, 27%) in subjects without HIV, as well as four in the HIV group (4/9, 44%).

On follow-up at month 12, “we saw something we did not expect. Strikingly, with no additional therapy in the interim, we saw a deepening of response in a number of subjects.” The overall response rate climbed to 63% (15/24), including 33% complete response in the HIV-free group (5/15) and HIV-positive group (3/9).

Some did lose their response in the interim, however, and the study team is working to figure out if it was do to a recurrence or a new infection.

A general pattern of immune activation on treatment, including increased systemic CD4+ T-cell responses to HPV during therapy, supported the investigator’s hunch of an immunologic mechanism of action, Dr. Polizzotto said.

There were four instances of grade 3 neutropenia over eight treatment cycles, and one possibly related angina attack, but other than that, adverse reactions were generally mild and self-limited, mostly to grade 1 or 2 neutropenia, constipation, fatigue, and rash, with no idiosyncratic reactions in the HIV group or loss of viral suppression, and no discontinuations because of side effects.

The men in the study were aged 40-50 years, with a median age of 54 years; all but one were white. The median lesion involved a quarter of the anal ring, but sometimes more than half.

The work was funded by the Cancer Institute of New South Wales, the Australian National Health and Medical Research Council, and Celgene. Dr. Polizzotto disclosed patents with Celgene and research funding from the company.

Increased visceral fat predicts both the presence of hepatic fibrosis in HIV patients with nonalcoholic fatty liver disease and also its progression, according to a report at the Conference on Retroviruses & Opportunistic Infections.

Among 58 people with NAFLD and well-controlled HIV, mostly men, a “striking 43% had evidence of fibrosis” on liver biopsy, a quarter with severe stage 3 fibrosis. Visceral fat content on MRI predicted fibrosis (284 cm² among fibrotic patients vs. 212 cm² among nonfibrotic patients, P = .005), but body mass index (BMI), waist circumference, subcutaneous fat, and hepatic fat content did not, said investigators led by Lindsay Fourman, MD, an attending physician at the Neuroendocrine & Pituitary Tumor Clinical Center at Massachusetts General Hospital, Boston.

Among 24 subjects with a second liver biopsy a year later, 38% had fibrosis progression, more than half from no fibrosis at baseline. Baseline visceral fat (306 cm² among progressors versus 212 cm², P = .04) again predicted progression, after adjustment for baseline BMI, hepatic fat content, and NAFLD activity score.

For every 25 cm² rise in baseline visceral fat, the team found a 40% increased odds of fibrosis progression (P = .03). Body mass index was stable among subjects, so progression was not related to sudden weight gain. Dr. Fourman noted that people with HIV can have normal BMIs, but still significant accumulation of visceral fat.

The mean rate of progression was 0.2 stages per year. “To put this into perspective, the rate of fibrosis progression among NAFLD in the general population has been quoted to be about 0.03 stages per year.” Among HIV patients, it’s “more than sixfold higher,” she said in a video presentation of her research at the meeting, which was presented online this year. CROI organizers chose to hold a virtual meeting due to concerns about the spread of COVID-19.

Overall, visceral adiposity is “a novel clinical predictor of accelerated” progression in people with HIV. “Therapies to reduce visceral fat may be particularly effective in HIV-associated NAFLD,” she said.

The findings come from a trial of one such therapy, the growth hormone releasing hormone analogue tesamorelin (Egrifta). It’s approved for reduction of excess abdominal fat in HIV patients with lipodystrophy. Dr. Fourman and her colleagues recently reported a more than 30% reduction in liver fat, versus placebo, among HIV patients with NAFLD after a year of treatment, and a lower rate of fibrosis progression at 10.5% versus 37.5% (Lancet HIV. 2019 Dec;6[12]:e821-30).

In their follow-up study reported at the meeting, people with fibrosis at baseline also had higher NAFLD activity scores (3.6 points vs. 2.0 points; P < .0001), as well as higher ALT (41 U/L vs. 23 U/L, P = .002) and AST levels (44 U/L vs. 24 U/L; P = .0003).

Baseline BMI, liver fat content, NAFLD activity score, liver enzymes, waist circumference, CD4 count, and HIV duration, a median of 16 years in the study, did not predict progression, but activity scores, hemoglobin A_1C, and C-reactive protein increased as fibrosis progressed.

“We really can’t speak from our own data” if HIV regimens might have had a role in progression. Sixty-two percent of the subjects were on integrase inhibitors, and integrase inhibitors are associated with weight gain, but their effect on visceral weight gain is unclear, plus BMIs were stable. Also, there was no difference in HIV regimens among the more than 100 people screened for the study between those with NAFDL and those without.

The subjects were 54 years old, on average. The average liver fat content at baseline was about 14%, and average baseline BMI just over 30 kg/m². In addition to the 62% on integrase inhibitors, 40% were on nonnucleoside reverse transcriptase inhibitors, and 24% were on protease inhibitors.

Fecal microbiota transplantation (FMT) appears safe and effective for treating recurrent Clostridioides difficile infection in patients with inflammatory bowel disease (IBD), according to an ongoing prospective trial.

Most patients were cured of C. difficile after one fecal transplant, reported Jessica Allegretti, MD, associate director of the Crohn’s and Colitis Center at Brigham and Women’s Hospital in Boston.

“[For patients without IBD], fecal microbiota transplantation has been shown to be very effective for the treatment of recurrent C. diff,” Dr. Allegretti said at the annual Gut Microbiota for Health World Summit.

But similar data for patients with IBD are scarce, and this knowledge gap has high clinical relevance, Dr. Allegretti said. She noted that C. difficile infections are eight times more common among patients with IBD, and risk of recurrence is increased 4.5-fold.

According to Dr. Allegretti, three small clinical trials have tested FMT for treating recurrent C. difficile infections in patients with IBD.

“[These studies were] somewhat prospective, but [data] mainly retrospectively collected, as they relied heavily on chart review for the assessment of IBD disease activity,” she said at the meeting sponsored by the American Gastroenterological Association and the European Society for Neurogastroenterology and Motility..

Across the trials, C. difficile infection cure rates were comparable with non-IBD cohorts; but disease flare rates ranged from 17.9% to 54%, which raised concern that FMT may trigger inflammation.

To investigate further, Dr. Allegretti and her colleagues designed a prospective trial that is set to enroll 50 patients with IBD. Among 37 patients treated to date, a slight majority were women (56.8%), about one-third had Crohn’s disease (37.8%), and two-thirds had ulcerative colitis (62.2%). The average baseline calprotectin level, which measures inflammation in the intestines, was 1,804.8 microg/g of feces, which is far above the upper limit of 50 microg/g.

“This is a very inflamed patient population,” Dr. Allegretti said.

Out of these 37 patients, 34 (92%) were cured of C. difficile infection after only one fecal transplant, and the remaining three patients were cured after a second FMT.

“They all did very well,” Dr. Allegretti said.

Concerning IBD clinical scores, all patients with Crohn’s disease either had unchanged or improved disease. Among those with ulcerative colitis, almost all had unchanged or improved disease, except for one patient who had a de novo flare.

Early microbiome analyses showed patients had increased alpha diversity and richness after FMT that was sustained through week 12. Because only three patients had recurrence, numbers were too small to generate predictive data based on relative abundance.

Dr. Allegretti continued her presentation with a review of FMT for IBD in general.

“For Crohn’s disease, the role [of microbiome manipulation] seems a bit more clear,” Dr. Allegretti said, considering multiple effective treatments that alter gut flora, such as antibiotics.

In contrast, the role for microbiome manipulation in treating ulcerative colitis “has remained a bit unclear,” she said. Although some probiotics appear effective for treating mild disease, other microbiome-altering treatments, such as diversion of fecal stream, antibiotics, and bowel rest, have fallen short.

Still, pooled data from four randomized clinical trials showed that FMT led to remission in 28% of patients with ulcerative colitis, compared with 9% who receive placebo.

“You may be thinking that seems a bit underwhelming compared to the 90% or so cure rate we get for C. diff trials,” Dr. Allegretti said. “However, if you look at our other biologic trials in IBD, 28% puts FMT on par with our other IBD therapies.”

According to Dr. Allegretti, at least three stool-based, FMT-like therapeutics are poised to become commercially available in the next few years for the treatment of C. difficile infection, including broad- and narrow-spectrum enema bags and oral capsules.

“I certainly think we will start to see off-label usage in our IBD patients, and we will start to have an easier and more systemic way of utilizing these microbiome-based therapies,” Dr. Allegretti said. “They will be coming to market, and when they do, whether or not we are allowed to still do traditional FMT in its current form remains unseen. The FDA may not allow us to do that in the future when we have an FDA-approved product.”Dr. Allegretti disclosed relationships with Merck, Openbiome, Finch Therapeutics, and others.

But similar data for patients with IBD are scarce, and this knowledge gap has high clinical relevance, Dr. Allegretti said. She noted that C. difficile infections are eight times more common among patients with IBD, and risk of recurrence is increased 4.5-fold.

According to Dr. Allegretti, three small clinical trials have tested FMT for treating recurrent C. difficile infections in patients with IBD.

“[These studies were] somewhat prospective, but [data] mainly retrospectively collected, as they relied heavily on chart review for the assessment of IBD disease activity,” she said at the meeting sponsored by the American Gastroenterological Association and the European Society for Neurogastroenterology and Motility..

Across the trials, C. difficile infection cure rates were comparable with non-IBD cohorts; but disease flare rates ranged from 17.9% to 54%, which raised concern that FMT may trigger inflammation.

To investigate further, Dr. Allegretti and her colleagues designed a prospective trial that is set to enroll 50 patients with IBD. Among 37 patients treated to date, a slight majority were women (56.8%), about one-third had Crohn’s disease (37.8%), and two-thirds had ulcerative colitis (62.2%). The average baseline calprotectin level, which measures inflammation in the intestines, was 1,804.8 microg/g of feces, which is far above the upper limit of 50 microg/g.

“This is a very inflamed patient population,” Dr. Allegretti said.

Out of these 37 patients, 34 (92%) were cured of C. difficile infection after only one fecal transplant, and the remaining three patients were cured after a second FMT.

“They all did very well,” Dr. Allegretti said.

Concerning IBD clinical scores, all patients with Crohn’s disease either had unchanged or improved disease. Among those with ulcerative colitis, almost all had unchanged or improved disease, except for one patient who had a de novo flare.

Early microbiome analyses showed patients had increased alpha diversity and richness after FMT that was sustained through week 12. Because only three patients had recurrence, numbers were too small to generate predictive data based on relative abundance.

Dr. Allegretti continued her presentation with a review of FMT for IBD in general.

“For Crohn’s disease, the role [of microbiome manipulation] seems a bit more clear,” Dr. Allegretti said, considering multiple effective treatments that alter gut flora, such as antibiotics.

In contrast, the role for microbiome manipulation in treating ulcerative colitis “has remained a bit unclear,” she said. Although some probiotics appear effective for treating mild disease, other microbiome-altering treatments, such as diversion of fecal stream, antibiotics, and bowel rest, have fallen short.

Still, pooled data from four randomized clinical trials showed that FMT led to remission in 28% of patients with ulcerative colitis, compared with 9% who receive placebo.

“You may be thinking that seems a bit underwhelming compared to the 90% or so cure rate we get for C. diff trials,” Dr. Allegretti said. “However, if you look at our other biologic trials in IBD, 28% puts FMT on par with our other IBD therapies.”

According to Dr. Allegretti, at least three stool-based, FMT-like therapeutics are poised to become commercially available in the next few years for the treatment of C. difficile infection, including broad- and narrow-spectrum enema bags and oral capsules.

“I certainly think we will start to see off-label usage in our IBD patients, and we will start to have an easier and more systemic way of utilizing these microbiome-based therapies,” Dr. Allegretti said. “They will be coming to market, and when they do, whether or not we are allowed to still do traditional FMT in its current form remains unseen. The FDA may not allow us to do that in the future when we have an FDA-approved product.”Dr. Allegretti disclosed relationships with Merck, Openbiome, Finch Therapeutics, and others.

Fecal microbiota transplantation (FMT) appears safe and effective for treating recurrent Clostridioides difficile infection in patients with inflammatory bowel disease (IBD), according to an ongoing prospective trial.

Most patients were cured of C. difficile after one fecal transplant, reported Jessica Allegretti, MD, associate director of the Crohn’s and Colitis Center at Brigham and Women’s Hospital in Boston.

GRAPEVINE, TEX. – Among women with twin pregnancy and a short cervix, the Arabin cervical pessary did not significantly affect the likelihood of preterm birth or a composite measure of adverse neonatal outcomes, according to a randomized, open-label study.

Jake Remaly/MDedge News

“The Arabin pessary should not be used to prevent preterm birth in women with twin pregnancy,” Jane E. Norman, MD, dean of health sciences at the University of Bristol (England), said at the Pregnancy Meeting.

“Preterm birth is very common in twin pregnancy” and leads to “excess neonatal mortality amongst twins,” Dr. Norman said at the meeting, which is sponsored by the Society for Maternal-Fetal Medicine. “Preventing preterm birth is important for both singletons and twins, but it could have even more benefits in twins.”

Emerging evidence has suggested that the Arabin cervical pessary may be useful for the prevention of preterm birth in women with singleton pregnancy and a short cervix. In twin pregnancy, data are more limited.

The ProTwin study randomized 813 women with twin pregnancy to a cervical pessary or standard care. Although the pessary had no impact on preterm birth overall, among women with cervical length of less than 38 mm, those who received a pessary were less likely to have preterm birth. The sample size was small, however, and the average length of the cervix in ProTwin differed from that in a previous U.K. study, Dr. Norman said.

Inspired by the study, Dr. Norman and coinvestigators conducted STOPPIT-2, a multicenter, open-label, randomized, controlled trial to further study whether a certain cervical length threshold was associated with benefit of a cervical pessary in preventing preterm birth. The trial included women with twin pregnancy who had a cervical length ultrasound between 18 and 20 weeks and 6 days of gestation. Women with a cervical length of 35 mm or less were eligible for randomization. Patients received an Arabin pessary plus standard care or standard care alone.

The primary obstetric outcome was spontaneous onset of labor leading to delivery before 34 weeks and 6 days of gestation. The primary neonatal outcome was a composite of outcomes – stillbirth, neonatal death, periventricular leukomalacia, respiratory morbidity, intraventricular hemorrhage, necrotizing enterocolitis, or sepsis – measured up to 28 days after the expected date of delivery.

The investigators randomized 503 women in all, including 250 to the pessary and 253 to standard care. Both groups had similar baseline characteristics, Dr. Norman said. The average age was about 33 years, and the average cervical length was about 29 mm. A total of 20% had monochorionic diamniotic pregnancies, and 80% had dichorionic pregnancies. The researchers excluded women with monochorionic monoamniotic pregnancies. In the pessary group, 16 patients declined the intervention, and 4 were unable to have the pessary inserted.

Spontaneous preterm birth occurred in 18% of patients in the Arabin pessary group, compared with 21% in the standard treatment group. The adjusted odds ratio, 0.87, was not statistically significant. In subgroups of patients with monochorionic pregnancy, cervical length less than 28 mm, or cervical length less than 25 mm, there was no significant benefit.

The composite measure of adverse neonatal outcomes also did not significantly differ between the groups. None of the individual components indicated benefit of the pessary either, Dr. Norman said.

In subgroup analyses, odds ratios for adverse neonatal outcomes were “tending towards harm for the Arabin pessary group ... although clearly none of them conferring statistical significance,” she said. Among women with cervical length less than 28 mm, a primary neonatal outcome – at least one of the adverse outcomes – occurred in 23% of patients in the Arabin pessary group, compared with 20% of patients in the standard care group.

Approximately two-thirds of patients found pessary insertion painless or slightly uncomfortable, whereas about 10% described the experience of device fitting as very uncomfortable, and about 1% described it as the worse pain imaginable.

“Since we started STOPPIT-2, in addition to ProTwin, another three studies have been published on the efficacy of the Arabin pessary in twins,” said Dr. Norman. Combined data show no significant effect of the pessary on preventing preterm birth in twin pregnancy. Still, the meta-analysis does not rule out the possibility that there could subgroups of patients who may benefit from the intervention, Dr. Norman said.

STOPPIT-2 was funded by the National Institute for Health Research (NIHR) in the United Kingdom. Dr. Norman chaired the UK National Institute for Health and Care Excellence guidelines on preterm labor and birth in 2015. In addition, Dr. Norman was a member of a GlaxoSmithKline data safety and monitoring group for a trial of a preterm birth prevention agent, has consulted for Dilafor, and has received research grants for preterm birth prevention from the U.K. Medical Research Council, NIHR, and Tommy’s: Together, for every baby charity.
