HIV

Women with HIV had more bone mobilization during lactation, and attenuated skeletal recovery after lactation, compared with HIV-negative women, according to research presented 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.

The study “demonstrated that there were reductions as expected in BMD during breastfeeding, and there was recovery at the end of breastfeeding, which was higher among women who were not HIV-infected compared to HIV-infected women,” said Mary Glenn Fowler, MD, speaking in a video presentation during the virtual conference. The differences between women who had HIV and the HIV-negative reference group were statistically significant (P = .003 for lumbar spine and P less than .001 for whole-body aBMD).

“We also saw that for whole-body BMD, there was recovery at the end of breastfeeding for women who were not HIV infected, but a dampened response of recovery for BMD for HIV-infected women,” she went on, adding: “These findings held after adjustment for parity, age, body mass, breastfeeding practices, duration of breastfeeding, use of [injectable medroxyprogesterone acetate], and resumption of menses.”

Dr. Fowler presented the study’s results on behalf of lead author Florence Nabwire, PhD, an investigator scientist in the nutrition and bone health group of the United Kingdom’s Medical Research Council (Cambridge).

Although it’s known that antiretroviral therapy (ART) is associated with bone loss, Dr. Fowler explained that there are only limited data in HIV-positive women who are lactating. It’s important to see what happens during lactation for this group of women because of the potential sequelae later in life of insufficient recovery from the physiological bone mobilization that occurs during lactation. The study looked at changes in areal bone mineral density (aBMD) both during and after lactation for women with HIV living in Uganda who were taking Option B+ ART, a regimen that includes tenofovir, 3TC, and efavirenz. These women were compared with a reference group of HIV-negative women.

In all, 95 women with HIV and 96 HIV negative women were recruited into the study during pregnancy. Participants were followed postpartum at weeks 2, 14, and 26, and at a final visit that occurred 14 weeks after lactation stopped.

In addition to lumbar spine, total hip, and femoral neck aBMD measurements, the investigators also obtained whole body-less-head reading.

For total hip and femoral neck aBMD, the nadir of density was seen at 26 postpartum, when a drop of about 6% was seen from baseline readings. By the final post-lactation visit, women without HIV had recovered to their baseline; for women with HIV, some recovery also occurred, but the effect was dampened, with a persistent bone density deficit of about 3% from baseline. The differences between HIV-positive and HIV-negative women in these measurements were also statistically significant, at P less than .001 for total hip aBMD differences and P = .0008 for femoral neck differences. Again, correction for multiple confounders didn’t attenuate the results, said Dr. Fowler.

“In conclusion, these data showed accentuated mobilization of hip and whole body aBMD during lactation,” said Dr. Fowler, who also noted “slower skeletal recovery post lactation for HIV-infected women.” Clinical implications of these findings aren’t currently known, she said. Further ongoing studies are aiming to tease out both mechanisms and longer-term consequences for the bone health of HIV-infected women and their children, who may also see differences in bone mineral accretion and growth.

Session moderator Risa Hoffman, MD, in introductory remarks, set the findings in some context. “As we know, HIV-positive adults have low bone mineral density, and this appears to be a result of interactions of HIV, traditional risk factors for loss of bone density, and antiretroviral therapy,” said Dr. Hoffman, director of the global health program at the University of California, Los Angeles. She added that previous work had shown that “middle-aged HIV-positive women have higher 10-year fracture incidence compared to their HIV-negative counterparts.” The current study, she said, “has both short- and long-term implications for women as they go through multiple pregnancies and multiple periods of breastfeeding.”

The study was funded by the United Kingdom’s Medical Research Council and Department for International Development as well as the Alborada Trust and the Gates Cambridge Scholarship. The authors reported no conflicts of interest.

Consider nucleoside reverse transcriptase inhibitors (NRTIs) prescribed for HIV infection as a possible cause of neutrophilic eccrine hidradenitis (NEH) arising in an affected patient, Jessica Kalen, MD, advised during a virtual meeting held by the George Washington University department of dermatology.

The virtual meeting included presentations that had been slated for the annual meeting of the American Academy of Dermatology, which was canceled because of the COVID-19 pandemic.

In a presentation entitled, “When HAART [highly active antiretroviral therapy] Hurts,” Dr. Kalen, a dermatology resident at the university, presented a case report involving a 65-year-old man who presented with juicy red edematous papules and plaques on his scalp and ears. He was on the three-drug combination of rilpivirine (a non-nucleoside reverse transcriptase inhibitor), and the NRTIs tenofovir, and emtricitabine (Odefsey) for treatment of HIV infection, which was well controlled, with no detectable viral load.

The patient was also on insulin detemir for diabetes; pravastatin, amlodipine, and lisinopril for hypertension; and episodic acyclovir for recurrent herpes simplex outbreaks. However, none of those drugs has been associated with NEH. In contrast, Dr. Kalen found three published case reports describing a link between NRTIs and NEH.

Lesional biopsy of her patient showed the classic features of NEH: a dermal neutrophilic infiltrate surrounding the eccrine secretory coils and ducts, with vacuolar degeneration that spared the acrosyringium.

The most common causes of NEH, a rare dermatologic disorder first described in 1982, are hematologic malignancies and some of the chemotherapeutic agents used in treating them. Particularly prominent are acute myelogenous leukemia and cytarabine, which are often prescribed for that cancer. Carbamazepine, granulocyte-colony stimulating factor, and BRAF inhibitors have also been associated with NEH.

The pathogenesis of NEH is not fully worked out; however, NRTIs are secreted via eccrine structures, and that close contact could potentially promote an environment favoring inflammation and destruction of the eccrine coils. Also, NRTIs inhibit DNA polymerase, as does cytarabine, Dr. Kalen noted.

Her patient’s NEH was treated with triamcinolone. His skin condition resolved completely while he remained on NRTI therapy, with no relapses to date.

Dr. Kalen reported having no financial conflicts regarding her presentation.

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.

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.

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.

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.

A pair of focus groups explored the experience of transgender patients with HIV prevention, finding many were discouraged by experiences of care that was not culturally competent and affirming.

The findings, including other important themes, were published in Pediatrics.

The pair of online asynchronous focus groups, conducted by Holly B. Fontenot, PhD, RN/NP, of the Fenway Institute in Boston, and colleagues, sought input from 30 transgender participants from across the United States. Eleven were aged 13-18 years, and 19 were aged 18-24 years, with an average age of 19. Most (70%) were white, and the remainder were African American (7%), Asian American (3%), multiracial (17%), and other (3%); 10% identified as Hispanic. Participants were given multiple options for reporting gender identity; 27% reported identifying as transgender males, 17% reported identifying as transgender females, and the rest identified with other terms, including 27% using one or more terms.

The quantitative analysis found four common themes, which the study explored in depth: “barriers to self-efficacy in sexual decision making; safety concerns, fear, and other challenges in forming romantic and/or sexual relationships; need for support and education; and desire for affirmative and culturally competent experiences and interactions.”

Based on their findings, the authors suggested ways of improving transgender youth experiences:

• Increasing provider knowledge and skills in providing affirming care through transgender health education programs.
• Addressing the barriers, such as stigma and lack of accessibility.
• Expanding sexual health education to be more inclusive regarding gender identities, sexual orientations, and definitions of sex.

Providers also need to include information on sexually transmitted infection and HIV prevention, including “discussion of safer sexual behaviors, negotiation and consent, sexual and physical assault, condoms, lubrication, STI and HIV testing, human papillomavirus vaccination, and PrEP [preexposure prophylaxis]” the authors emphasized.

Dr. Fontenot and associates determined that this study’s findings were consistent with what’s known about adult transgender patients, but this study provides more context regarding transgender youth experiences.

“It is important to elicit transgender youth experiences and perspectives related to HIV risk and preventive services,” they concluded. “This study provided a greater understanding of barriers to and facilitators of youth obtaining HIV preventive services and sexual health education.”

Limitations of the study included that non–English speaking participants were excluded, and that participants were predominantly white, non-Hispanic, and assigned female sex at birth.

This study was funded by the Centers for Disease Control and Prevention and NORC at The University of Chicago. The authors had no relevant financial disclosures.

Testing rates for HIV in adolescents and young adults with sexually transmitted infections (STIs) are suboptimal, according to Danielle Petsis, MPH, of the Children’s Hospital of Philadelphia, and associates.

In a study published in Pediatrics, the investigators conducted a retrospective analysis of 1,816 acute STI events from 1,313 patients aged 13-24 years admitted between July 2014 and Dec. 2017 at two urban health care clinics. The most common STIs in the analysis were Chlamydia, gonorrhea, trichomoniasis, and syphilis; the mean age at diagnosis was 17 years, 71% of episodes occurred in females, and 97% occurred in African American patients.

Of the 1,816 events, HIV testing was completed within 90 days of the STI diagnosis for only 55%; there was 1 confirmed HIV diagnosis among the completed tests. When HIV testing did occur, in 38% of cases it was completed concurrently with STI testing or HIV testing was performed in 35% of the 872 follow-up cases. Of the 815 events where HIV testing was not performed, 27% had a test ordered by the provider but not completed by the patient; the patient leaving the laboratory before the test could be performed was the most common reason for test noncompletion (67%), followed by not showing up at all (18%) and errors in the medical record or laboratory (5%); the remaining patients gave as reasons for test noncompletion: declining an HIV test, a closed lab, or no reason.

Logistic regression showed that participants who were female and those with a previous history of STIs had significantly lower adjusted odds of HIV test completion, compared with males and those with no previous history of STIs, respectively, the investigators said. In addition, having insurance and having a family planning visit were associated with decreased odds of HIV testing, compared with not having insurance or a family planning visit.

“As we enter the fourth decade of the HIV epidemic, it remains clear that missed opportunities for diagnosis have the potential to delay HIV diagnosis and linkage to antiretroviral therapy or PrEP and prevention services, thus increasing the population risk of HIV transmission. Our data underscore the need for improved HIV testing education for providers of all levels of training and the need for public health agencies to clearly communicate the need for testing at the time of STI infection to reduce the number of missed opportunities for testing,” Ms. Petsis and colleagues concluded.

The study was supported by the National Institutes of Mental Health and the Children’s Hospital of Philadelphia Research Institute K-Readiness Award.

In a study published in Pediatrics, the investigators conducted a retrospective analysis of 1,816 acute STI events from 1,313 patients aged 13-24 years admitted between July 2014 and Dec. 2017 at two urban health care clinics. The most common STIs in the analysis were Chlamydia, gonorrhea, trichomoniasis, and syphilis; the mean age at diagnosis was 17 years, 71% of episodes occurred in females, and 97% occurred in African American patients.

Of the 1,816 events, HIV testing was completed within 90 days of the STI diagnosis for only 55%; there was 1 confirmed HIV diagnosis among the completed tests. When HIV testing did occur, in 38% of cases it was completed concurrently with STI testing or HIV testing was performed in 35% of the 872 follow-up cases. Of the 815 events where HIV testing was not performed, 27% had a test ordered by the provider but not completed by the patient; the patient leaving the laboratory before the test could be performed was the most common reason for test noncompletion (67%), followed by not showing up at all (18%) and errors in the medical record or laboratory (5%); the remaining patients gave as reasons for test noncompletion: declining an HIV test, a closed lab, or no reason.

A simple, quick point-of-care urine test for tenofovir adherence, similar to an OTC-pregnancy test, has an accuracy of 99.6% versus laboratory testing, according to a report at the Conference on Retroviruses & Opportunistic Infections.

A few drops of urine yield results in 5 minutes, and tell if patients have been taking tenofovir, a key component of HIV preexposure prophylaxis (PrEP) medications, within the previous 4-7 days. Abbott Rapid Diagnostics is gearing up to market the test widely in the United States, and it won’t be very expensive, according to lead investigator Matthew Spinelli, MD, a clinical fellow and HIV/AIDS researcher at the University of California, San Francisco.

It’s an alternative to the usual approach, measuring tenofovir levels in hair, blood, or urine by liquid chromatography and mass spectrometry. That approach is expensive and requires trained personnel, and the results can take a while. Dr. Spinelli and colleagues saw the need for a quicker, easier way for use in the clinic, since real-time adherence results are most likely to make a difference, he said at the meeting, which was scheduled to be in Boston, but was held online instead this year because of concerns about spreading the COVID-19 virus.

Self-report, meanwhile, is notoriously unreliable. Over 90% of people in two previous PrEP studies said they were taking their medications, but only about a quarter had tenofovir in their plasma.

The investigators identified a tenofovir antibody in urine that could be read by enzyme-linked immunosorbent assay (ELISA), and validated it for adherence accuracy against liquid chromatography and mass spectrometry; they then put the antibody on a test strip to create a lateral flow immunoassay.

After hearing the presentation, moderator Susan Buchbinder, MD, director of HIV prevention research at the San Francisco Department of Public Health, called the work “important” and said it “really has the possibility of opening up a lot of new kinds of studies and new kinds of intervention for both prevention and treatment.”

Dr. Spinelli and colleagues pitted the test strip against their laboratory-based ELISA test using 684 stored urine samples from 324 men and women in disoproxil fumarate/emtricitabine (Truvada) PrEP projects in Africa and the United States.

Overall, the 505 samples that were positive for tenofovir in the lab test were also positive on the urine strip, yielding 100% sensitivity. Of the 179 negative samples on the lab test, 176 were also negative with the strip, yielding a specificity of 98.3%. The results calculated into nearly perfect accuracy.

“We believe that” the urine test strip “is ready for field testing,” and that “point-of-care adherence testing” will be a boon to both PrEP and HIV treatment. A negative test, for instance, would signal the need for immediate counseling, and the patient would still be in the office to hear it. For HIV, high adherence but also high viral load would signal the need for resistance testing, Dr. Spinelli said.

A white-coat effect is possible; people might take their medication when they know they have an upcoming doctor’s appointment. “We will need to evaluate for [that] with additional studies” comparing point-of-care testing with longer-term metrics, such as drug levels in hair, he said.

The study was published to coincide with Dr. Spinelli’s report (J Acquir Immune Defic Syndr. 2020 Mar 10. doi: 10.1097/QAI.0000000000002322).

The funding source wasn’t reported. Dr. Spinelli had no disclosures. Two investigators were Abbott employees.

Women with HIV on dolutegravir-based antiretroviral therapy (ART) protocols had higher weights through 18 months of the postpartum period than women on efavirenz-based therapy, according to a recent study. However, women taking dolutegravir had similar postpartum weights to women who did not have HIV infection.

The results were shared by Jennifer Jao, MD, MPH, of Northwestern University, Chicago, in a video presentation of the 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.

Dr. Jao, an internal medicine physician and pediatrician, and colleagues looked at the association between dolutegravir and postpartum weight for women with HIV, compared with women with HIV who were taking efavirenz-based ART and women who did not have HIV infection.

Though there was no significant difference among the three groups for body mass index at 4 weeks post partum (all were between 24 and 26 kg/m²), postpartum weight for the dolutegravir group was significantly higher.

Using a mixed models statistical approach that adjusted for potentially confounding variables, Dr. Jao and associates found that women on a dolutegravir-based regiment weighed an average of 5 kg more postpartum than women on an efavirenz-based regiment. (P less than .01).

Further adjustment that included CD4 count, viral load, and ART status at conception didn’t change the results from the original approach that included such variables as age, breastfeeding duration , gestational diabetes status, and second and third trimester weight gain (P = .04).

The study was a secondary analysis of the Tshilo Dikotla study conducted in Botswana. Dr. Jao said that the study addressed the known association of dolutegravir-based ART with higher weight gain than other ART regimens. Seeing how postpartum weight varies by regimen is important because “postpartum weight retention impacts cardiometabolic risk,” added Dr. Jao.

Of a total of 406 women, 170 were on dolutegravir-based therapy, 114 were on efavirenz-based therapy, and 122 weren’t HIV infected. Overall, the women on efavirenz-based therapy were older, with a median age of 33 years, compared with 28.5 and 25 years for the dolutegravir group and those without HIV, respectively. This and all other between-group differences were statistically significant at P less than .01.

Women without HIV had lower gravidity, with a median one pregnancy, compared with three in the other two groups. Other significant differences included a higher rate of weight gain in the second and third trimesters for the non–HIV-infected group, who gained at a rate of 0.3 kg/week, compared with 0.1 and 0.2 kg/week for the efavirenz and dolutegravir groups, respectively. Breastfeeding duration was longer in the non–HIV-infected group as well.

Finally, 86% of women on efavirenz-based therapy were on ART at the time of conception, compared with just 35.3% of women on dolutegravir-based treatment.

“Further studies to assess mechanisms of postpartum weight retention are needed,” said Dr. Jao.

The study was supported by the National Institutes of Health. Dr. Jao reported no relevant conflicts of interest.

A patient with HIV remission induced by stem cell transplantation continues to be disease free at the 30-month mark.

The individual, referred to as the London patient, received allogeneic hematopoietic stem cell transplantation (allo-HSCT) for stage IVB Hodgkin lymphoma. The transplant donor was homozygous for the CCR5 delta-32 mutation, which confers immunity to HIV because there’s no point of entry for the virus into immune cells.

After extensive sampling of various tissues, including gut, lymph node, blood, semen, and cerebrospinal fluid (CSF), Ravindra Kumar Gupta, MD, PhD, and colleagues found no detectable virus that was competent to replicate. However, they reported that the testing did detect some “fossilized” remnants of HIV DNA persisting in certain tissues.

The results were shared in a video presentation of the 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.

The London patient’s HIV status had been reported the previous year at CROI 2019, but only blood samples were used in that analysis.

In a commentary accompanying the simultaneously published study in the Lancet, Jennifer Zerbato, PhD, and Sharon Lewin, FRACP, PHD, FAAHMS, asked: “A key question now for the area of HIV cure is how soon can one know if someone has been cured of HIV?

“We will need more than a handful of patients cured of HIV to really understand the duration of follow-up needed and the likelihood of an unexpected late rebound in virus replication,” continued Dr. Zerbato, of the University of Melbourne, and Dr. Lewin, of the Royal Melbourne Hospital and Monash University, also in Melbourne.

In their ongoing analysis of data from the London patient, Dr. Gupta, a virologist at the University of Cambridge (England), and associates constructed a mathematical model that maps the probability for lifetime remission or cure of HIV against several factors, including the degree of chimerism achieved with the stem cell transplant.

In this model, when chimerism reaches 80% in total HIV target cells, the probability of remission for life is 98%; when donor chimerism reaches 90%, the probability of lifetime remission is greater than 99%. Peripheral T-cell chimerism in the London patient has held steady at 99%.

Dr. Gupta and associates obtained some testing opportunistically: A PET-CT scan revealed an axillary lymph node that was biopsied after it was found to have avid radiotracer uptake. Similarly, the CSF sample was obtained in the course of a work-up for some neurologic symptoms that the London patient was having.

In contrast to the first patient who achieved ongoing HIV remission from a pair of stem cell transplants received over 13 years ago – the Berlin patient – the London patient did not receive whole-body radiation, but rather underwent a reduced-intensity conditioning regimen. The London patient experienced a bout of gut graft-versus-host disease (GVHD) about 2 months after his transplant, but has been free of GVHD in the interval. He hasn’t taken cytotoxic agents or any GVHD prophylaxis since 6 months post transplant.

Though there’s no sign of HIV that’s competent to replicate, “the London patient has shown somewhat slow CD4 reconstitution,” said Dr. Gupta and coauthors in discussing the results.

The patient had a reactivation of Epstein-Barr virus (EBV) about 21 months after analytic treatment interruption (ATI) of antiretroviral therapy that was managed without any specific treatment, but he hasn’t experienced any opportunistic infections. However, his CD4 count didn’t rebound to pretransplant levels until 28 months after ATI. At that point, his CD4 count was 430 cells per mcL, or 23.5% of total T cells. The CD4:CD8 ratio was 0.86; normal range is 1.5-2.5.

The researchers used quantitative real-time polymerase chain reaction (rt-PCR) to look for packaging site and envelope (env) DNA fragments, and droplet digital PCR to quantify HIV-1 DNA.

The patient’s HIV-1 plasma load measured at 30 months post ATI on an ultrasensitive assay was below the lower limit of detection (less than 1 copy per mL). Semen viremia measured at 21 months was also below the lower limit of detection, as was CSF measured at 25 months.

Samples were taken from the patient’s rectum, cecum, sigmoid colon, and terminal ileum during a colonoscopy conducted 22 months post ATI; all tested negative for HIV DNA via droplet digital PCR.

The lymph node had large numbers of EBV-positive cells and was positive for HIV-1 env and long-terminal repeat by double-drop PCR, but no integrase DNA was detected. Additionally, no intact proviral DNA was found on assay.

Dr. Gupta and associates speculated that “EBV reactivation could have triggered EBV-specific CD4 and CD8 T-cell responses and proliferation, potentially including CD4 T cells containing HIV-1 DNA.” Supporting this hypothesis, EBV-specific CD8 T-cell responses in peripheral blood were “robust,” and the researchers also saw some CD4 response.

“Similar to the Berlin patient, highly sensitive tests showed very low levels of so-called fossilized HIV-1 DNA in some tissue samples from the London patient. Residual HIV-1 DNA and axillary lymph node tissue could represent a defective clone that expanded during hyperplasia within the lymph note sampled,” noted Dr. Gupta and coauthors.

Responses of CD4 and CD8 T cells to HIV have also remained below the limit of detection, though cytomegalovirus-specific responses persist in the London patient.

As with the Berlin patient, standard enzyme-linked immunosorbent assay (ELISA) testing has remained positive in the London patient. “Standard ELISA testing, therefore, cannot be used as a marker for cure, although more work needs to be done to assess the role of detuned low-avidity antibody assays in defining cure,” noted Dr. Gupta and associates.

The ongoing follow-up plan for the London patient is to obtain viral load testing twice yearly up to 5 years post ATI, and then obtain yearly tests for a total of 10 years. Ongoing testing will confirm the investigators’ belief that “these findings probably represent the second recorded HIV-1 cure after CCR5 delta-32/delta-32 allo-HSCT, with evidence of residual low-level HIV-1 DNA.”

Dr. Zerbato and Dr. Lewin advised cautious optimism and ongoing surveillance: “In view of the many cells sampled in this case, and the absence of any intact virus, is the London patient truly cured? The additional data provided in this follow-up case report is certainly exciting and encouraging but, in the end, only time will tell.”

A patient with HIV remission induced by stem cell transplantation continues to be disease free at the 30-month mark.

The individual, referred to as the London patient, received allogeneic hematopoietic stem cell transplantation (allo-HSCT) for stage IVB Hodgkin lymphoma. The transplant donor was homozygous for the CCR5 delta-32 mutation, which confers immunity to HIV because there’s no point of entry for the virus into immune cells.

After extensive sampling of various tissues, including gut, lymph node, blood, semen, and cerebrospinal fluid (CSF), Ravindra Kumar Gupta, MD, PhD, and colleagues found no detectable virus that was competent to replicate. However, they reported that the testing did detect some “fossilized” remnants of HIV DNA persisting in certain tissues.

The results were shared in a video presentation of the 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.

The London patient’s HIV status had been reported the previous year at CROI 2019, but only blood samples were used in that analysis.

In a commentary accompanying the simultaneously published study in the Lancet, Jennifer Zerbato, PhD, and Sharon Lewin, FRACP, PHD, FAAHMS, asked: “A key question now for the area of HIV cure is how soon can one know if someone has been cured of HIV?

“We will need more than a handful of patients cured of HIV to really understand the duration of follow-up needed and the likelihood of an unexpected late rebound in virus replication,” continued Dr. Zerbato, of the University of Melbourne, and Dr. Lewin, of the Royal Melbourne Hospital and Monash University, also in Melbourne.

In their ongoing analysis of data from the London patient, Dr. Gupta, a virologist at the University of Cambridge (England), and associates constructed a mathematical model that maps the probability for lifetime remission or cure of HIV against several factors, including the degree of chimerism achieved with the stem cell transplant.

In this model, when chimerism reaches 80% in total HIV target cells, the probability of remission for life is 98%; when donor chimerism reaches 90%, the probability of lifetime remission is greater than 99%. Peripheral T-cell chimerism in the London patient has held steady at 99%.

Dr. Gupta and associates obtained some testing opportunistically: A PET-CT scan revealed an axillary lymph node that was biopsied after it was found to have avid radiotracer uptake. Similarly, the CSF sample was obtained in the course of a work-up for some neurologic symptoms that the London patient was having.

In contrast to the first patient who achieved ongoing HIV remission from a pair of stem cell transplants received over 13 years ago – the Berlin patient – the London patient did not receive whole-body radiation, but rather underwent a reduced-intensity conditioning regimen. The London patient experienced a bout of gut graft-versus-host disease (GVHD) about 2 months after his transplant, but has been free of GVHD in the interval. He hasn’t taken cytotoxic agents or any GVHD prophylaxis since 6 months post transplant.

Though there’s no sign of HIV that’s competent to replicate, “the London patient has shown somewhat slow CD4 reconstitution,” said Dr. Gupta and coauthors in discussing the results.

The patient had a reactivation of Epstein-Barr virus (EBV) about 21 months after analytic treatment interruption (ATI) of antiretroviral therapy that was managed without any specific treatment, but he hasn’t experienced any opportunistic infections. However, his CD4 count didn’t rebound to pretransplant levels until 28 months after ATI. At that point, his CD4 count was 430 cells per mcL, or 23.5% of total T cells. The CD4:CD8 ratio was 0.86; normal range is 1.5-2.5.

The researchers used quantitative real-time polymerase chain reaction (rt-PCR) to look for packaging site and envelope (env) DNA fragments, and droplet digital PCR to quantify HIV-1 DNA.

The patient’s HIV-1 plasma load measured at 30 months post ATI on an ultrasensitive assay was below the lower limit of detection (less than 1 copy per mL). Semen viremia measured at 21 months was also below the lower limit of detection, as was CSF measured at 25 months.

Samples were taken from the patient’s rectum, cecum, sigmoid colon, and terminal ileum during a colonoscopy conducted 22 months post ATI; all tested negative for HIV DNA via droplet digital PCR.

The lymph node had large numbers of EBV-positive cells and was positive for HIV-1 env and long-terminal repeat by double-drop PCR, but no integrase DNA was detected. Additionally, no intact proviral DNA was found on assay.

Dr. Gupta and associates speculated that “EBV reactivation could have triggered EBV-specific CD4 and CD8 T-cell responses and proliferation, potentially including CD4 T cells containing HIV-1 DNA.” Supporting this hypothesis, EBV-specific CD8 T-cell responses in peripheral blood were “robust,” and the researchers also saw some CD4 response.

“Similar to the Berlin patient, highly sensitive tests showed very low levels of so-called fossilized HIV-1 DNA in some tissue samples from the London patient. Residual HIV-1 DNA and axillary lymph node tissue could represent a defective clone that expanded during hyperplasia within the lymph note sampled,” noted Dr. Gupta and coauthors.

Responses of CD4 and CD8 T cells to HIV have also remained below the limit of detection, though cytomegalovirus-specific responses persist in the London patient.

As with the Berlin patient, standard enzyme-linked immunosorbent assay (ELISA) testing has remained positive in the London patient. “Standard ELISA testing, therefore, cannot be used as a marker for cure, although more work needs to be done to assess the role of detuned low-avidity antibody assays in defining cure,” noted Dr. Gupta and associates.
