TDF preferred in PrEP for Blacks and women, studies indicate
Although the efficacy of two pre-exposure prophylaxis (PrEP) regimens containing differing prodrug formulations of tenofovir are virtually identical, the balance between benefit and risk tips in favor of the combination using the older formulation, tenofovir disoproxil fumarate (TDF), a pharmacology researcher said.
An analysis of the pharmacologic profiles of TDF plus emtricitabine (FTC; Truvada and generic) with tenofovir alafenamide (TAF) plus FTC (Descovy) shows that the risk of decreased bone mineral density and renal toxicity with TDF are significantly lower than those of weight gain and related metabolic and cardiovascular problems associated with the newer tenofovir formulation TAF, according to pharmacology research fellow Andrew Hill, MD, PhD, from the University of Liverpool (England).
“I think when we’re comparing these two drugs overall, we have a clear benefit/risk, and we need to take both of these potential toxicities seriously, “ he said in an online presentation during IDWeek 2020, an annual scientific meeting on infectious diseases held virtually this year.
“But in my view, treating women – Black women – with TAF/FTC is a bad thing,” he continued. “I think it’s going lead to more harm, more myocardial infarctions, more cases of diabetes, and potentially more adverse birth outcomes, and I think that is a risk that is not worth taking, given that the apparent benefit in terms of bone mineral density and renal markers is a hypothesis at best, and is not translated into hard clinical endpoints.”
Adverse event profiles
Dr. Hill compared the side effect profiles of the two agents when used both in antiretroviral therapy (ART) in combination the integrase inhibitor dolutegravir (DTG; Tivicay), and in PrEP.
World Health Organization guidelines for first-line ART recommend the use of TDF/FTC/DTG, reserving TAF plus lamivudine (3TC) and DTG for use in special circumstances only, Dr. Hill noted.
He pointed to a pooled analysis of data from eight randomized, controlled trials of treatment-naive people living with HIV who started on ART from 2003 to 2015. The authors found that demographic factors associated with weight gain included lower CD4 cell counter, higher levels of HIV type 1 RNA, no injection drug use, female sex, and Black race.
They also found that, among nucleoside/nucleotide reverse transcriptase inhibitors, TAF was associated with more weight gain than TDF, abacavir, or zidovudine.
“This pattern is seen consistently across studies both of pre-exposure prophylaxis or treatment comparing tenofovir with either TAF or other nucleoside analogs,” he said.
The greater weight gain with TAF versus TDF was seen in both treatment trials and in the DISCOVER PrEP trial.
In addition, in a crossover trial conducted in Germany, patients who switched from TDF to TAF had an approximately 2 kg increase in body weight.
TAF has also been associated with higher grade 3 or 4 glucose and LDL cholesterol than TDF in clinical trials for the treatment of hepatitis B infections, and with higher LDL cholesterol and total cholesterol levels as well as diabetes in patients treated with the drugs in combination in the EMERALD HIV trial.
Clinical trials also tend to underestimate the real-world population of persons at highest risk for adverse events from TAF, Dr. Hill said, noting that the percentage of Black women in phase 3 trials for dolutegravir was 9%, compared with 42% among persons infected with HIV worldwide. The respective percentages for Black men are 16% versus 30%. These differences are similar across clinical trial programs for other ART agents.
“Generally, it’s women and Black people who seem to be at greatest risk for safety issues,” he said.
In the ADVANCE trial comparing TAF/FTC/DTG with TDF/FTC/DTG and a control arm of TDF, FTC and efavirenz, the mean change in weight among men after 3 years on the TAF-based regimen was a gain of 7.2 kg (15.9 lbs), compared with 5.5 kg (12 lbs) with TDF, and 2.6 kg (5.7 lbs) with the efavirenz-containing regimen.
In women enrolled in the same trial, the respective mean weight gains were 12.3 kg (27 lbs), 7.4 kg (16.3 lbs), and 5.5 kg (12 lbs).
“All of our analyses so far have shown that the weight continues to go up. We’re actually seeing people doubling in their body weight. We’ve seen some women come into clinic and their doctors don’t even recognize them because they’ve put on so much weight,” he said.
In women, most of the gain in weight occurs as limb or trunk fat, with a predominance of visceral fat.
People taking TAF in the trial were also at significantly greater risk for developing the metabolic syndrome, and at week 96, 27% of women on TAF/FTC/DTG had treatment-emergent obesity, compared with 17% for those on TDF/FTC/DTG and 11% for those on TDF/FTC/EFV. In men, the respective 96-week rates of treatment-emergent obesity were 7%, 3%, and 2%.
Clinical obesity itself is a risk factor for obstetric complications and birth outcomes, Alzheimer’s disease, type 2 diabetes, cardiovascular disease, hypertension and cancer, and an average 4-year reduction in life expectancy, Dr. Hill said. “I think it’s actually very unlikely that the [World Health Organization] guidelines will now change and allow the widespread use of TAF/FTC in combination with integrase inhibitors worldwide given these potential implications.”
Modern times
The bad rap that TDF gets for its alleged effects on bone mineral density and kidneys comes from studies where the drug was given in a boosted regimen that can amplify tenofovir toxicities, Dr. Hill said.
He noted that data from Gilead Sciences shows through 7 years of therapy in previously ART-naive patients, the combination of TDF/3TC/EFV showed sustained durable efficacy, no discontinuations to renal adverse effects, and no evidence of clinically relevant bone effects.
“I think we need to be very careful when we look at tenofovir and TAF. We need to look at the more modern way that these drugs are used, which is not with pharmacokinetic boosters anymore, and in that situation the toxicity profile of tenofovir/3TC – the original TDF – is very favorable,” he said.
Robert Goldstein, MD, PhD, an infectious disease specialist and medical director of the transgender health program at Massachusetts General Hospital in Boston, who comoderated the session where Dr. Hill presented his data, said that his clinical experience mirrors the pharmacokinetic findings.
“I certainly have strong feelings about the use of TDF in pre-exposure prophylaxis,” he said in an interview. “TDF is an effective and safe formulation of tenofovir to be used in pre-exposure prophylaxis, and one that we have more experience with. It’s the formulation of tenofovir that I use for all of my patients who are on pre-exposure prophylaxis, and I think it is the most cost-effective.’
No funding source was reported. Andrew Hill consults for Tibotec on clinical trial programs for darunavir, etravirine, and rilpivirine. Dr. Goldstein reported having no relevant disclosures.

FROM IDWEEK 2020
Shared decision-making aids choice of PrEP
A patient-centered approach can help guide persons at risk for HIV exposure to decide on the best choice of pre-exposure prophylaxis (PrEP) regimens for them, stifling the noise generated by direct-to-consumer advertising, an infectious disease specialist recommends.
The decision for patients whether to start or remain on the PrEP combination of tenofovir disoproxil fumarate (TDF) plus emtricitabine (FTC; Truvada and generic) or on tenofovir alafenamide (TAF) plus FTC (Descovy) is made more fraught by confusion regarding the use of the newer and allegedly safer TAF prodrug of tenofovir in HIV treatment regimens, said Oni Blackstock, MD, founder and executive director of Health Justice and an attending physician in the division of infectious diseases at Harlem Hospital, New York.
“There have been commercials on TV as well as on social media around class-action lawsuits against [Truvada maker] Gilead,” she said in an online presentation during IDWeek 2020, an annual scientific meeting on infectious diseases, held virtually this year.
“These lawsuits focus on TDF for HIV treatment, but they have sown a great deal of confusion about TDF versus TAF for PrEP among potential and actual PrEP users,” she added.
Dr. Blackstock described her approach to shared decision-making regarding TDF/FTC versus TAF/FTC, and to helping patients understand the relative benefits and risks of each formulation.
In January of 2020, Dr. Blackstock, who was then assistant commissioner of the HIV bureau of the New York City Department of Health and Mental Hygiene, issued with other Bureau members a “Dear colleague” letter stating why they believed that TDF/FTC should remain the first-line regimen for PrEP.
That opinion, she said, was bolstered by an editorial published in February 2020 by Douglas E. Krakower, MD, from Beth Israel Deaconess Medical Center in Boston, and colleagues, which questioned the rush to shift from TDF to TAF in HIV treatment, and cautioned against the same approach to PrEP.
“Despite evidence that TAF/FTC would not be cost-effective, compared with generic TDF/FTC , the newer regimen quickly and irrevocably displaced TDF/FTC for HIV treatment in the U.S. A similar shift for PrEP – especially for populations in which TAF/FTC is untested – would be premature, costly, and counterproductive for population impact,” Krakower et al. wrote.
Shared decision-making
Clinicians can help patients who may be a candidate for either PrEP regimen by engaging them in shared decision-making.
“The clinician provides information in this case about a prevention strategy, options, benefits and risks, alternatives, and the patient provides their preferences and values, and together the clinician and patient make a decision,” Dr. Blackstock said.
The process differs from the model of informed decision-making, where the clinician gives the patient the information and the patient comes to a decision, or the old, “paternalistic” model in which the clinician gives information and makes recommendations to the patient.
“Shared decision-making has been studied extensively and has been shown to improve patient satisfaction, patient communication, and also potentially reducing health inequities that we see,” she said.
The model for shared decision-making for clinical practice includes three distinct portions: a choice talk, option talk, and decision talk.
Choice
To begin the discussion, the physician informs the patients of the availability of choices and justifies them, saying, for example, “there is good information about how these two PrEP options differ that I’d like to discuss with you,” and “the two PrEP options have different side effects … some will matter more to you than other people.”
At this stage the clinician should defer closure by offering a more detailed discussion of the choices.
Option
Here the clinician solicits information about what the patient has heard or read about PrEP, describes each option in practical terms, and points out where the two regimens differ, being specific about the pros and cons of each (for example, potential bone mineral density loss or renal complications with TDF, and potential weight gain with subsequent metabolic and cardiovascular consequences with TAF).
The TDF versus TAF-based PrEP discussion could also focus on what’s known about the comparative effectiveness of each regimen.
For example, TDF/FTC has been shown to be about 99% effective at preventing infection in men who have sex with men and in transgender women, also about 99% effective in heterosexual women and men, and 74%-84% effective in persons who inject drugs.
In contrast, TAF/FTC has been shown to be about 99% effective in men who have sex with men and transgender women, but it’s efficacy in the other two categories is unknown, Dr. Blackstock said.
The option discussion should include a comparison of the evidence base for each regimen, including the real-world experience with TDF/FTC since 2012, and much more limited experience with TAF/FTC.
Discussing relative costs, although the wholesale costs of the regimens are similar, there is now a generic version of TDF/FTC made by Teva Pharmaceuticals that sells for about $400 less per month than the brand name, which might make the option more acceptable to health insurers.
Decision
The decision talk is about considering the patients preferences and deciding with them what is best.
The clinician could say, for example: “What, from your point of view, matters most to you?”
The clinician should also be willing to allow the patient to defer a decision or to guide them depending on their stated wish, asking something like: “Are you ready to decide, or do you want more time? Do you have more questions? Are there more things we should discuss?
Offering the patient a chance to review the decision can also be a good way to arrive at closure, Dr. Blackstock said.
Robert Goldstein, MD, PhD, an infectious disease specialist and medical director of the transgender health program at Massachusetts General Hospital in Boston, who comoderated the session where Dr. Blackstock presented her talk, said that he also uses a similar approach to the PrEP discussion.
“I use a very patient-centered approach of providing information and talking through the data that are available,” he said.
“I will say that, as patients come to me talking about the transition from TDF to TAF for pre-exposure prophylaxis, I am very clear with them about the limited benefit or no benefit that I see with TAF for pre-exposure prophylaxis, and all of my patients have remained on TDF for pre-exposure prophylaxis,” he added.
No funding source for the presentation was reported. Dr. Blackstock and Dr. Goldstein reported having no conflicts of interest to disclose.

“These lawsuits focus on TDF for HIV treatment, but they have sown a great deal of confusion about TDF versus TAF for PrEP among potential and actual PrEP users,” she added.
Dr. Blackstock described her approach to shared decision-making regarding TDF/FTC versus TAF/FTC, and to helping patients understand the relative benefits and risks of each formulation.
In January of 2020, Dr. Blackstock, who was then assistant commissioner of the HIV bureau of the New York City Department of Health and Mental Hygiene, issued with other Bureau members a “Dear colleague” letter stating why they believed that TDF/FTC should remain the first-line regimen for PrEP.
That opinion, she said, was bolstered by an editorial published in February 2020 by Douglas E. Krakower, MD, from Beth Israel Deaconess Medical Center in Boston, and colleagues, which questioned the rush to shift from TDF to TAF in HIV treatment, and cautioned against the same approach to PrEP.
“Despite evidence that TAF/FTC would not be cost-effective, compared with generic TDF/FTC , the newer regimen quickly and irrevocably displaced TDF/FTC for HIV treatment in the U.S. A similar shift for PrEP – especially for populations in which TAF/FTC is untested – would be premature, costly, and counterproductive for population impact,” Krakower et al. wrote.
Shared decision-making
Clinicians can help patients who may be a candidate for either PrEP regimen by engaging them in shared decision-making.
“The clinician provides information in this case about a prevention strategy, options, benefits and risks, alternatives, and the patient provides their preferences and values, and together the clinician and patient make a decision,” Dr. Blackstock said.
The process differs from the model of informed decision-making, where the clinician gives the patient the information and the patient comes to a decision, or the old, “paternalistic” model in which the clinician gives information and makes recommendations to the patient.
“Shared decision-making has been studied extensively and has been shown to improve patient satisfaction, patient communication, and also potentially reducing health inequities that we see,” she said.
The model for shared decision-making for clinical practice includes three distinct portions: a choice talk, option talk, and decision talk.
Choice
To begin the discussion, the physician informs the patients of the availability of choices and justifies them, saying, for example, “there is good information about how these two PrEP options differ that I’d like to discuss with you,” and “the two PrEP options have different side effects … some will matter more to you than other people.”
At this stage the clinician should defer closure by offering a more detailed discussion of the choices.
Option
Here the clinician solicits information about what the patient has heard or read about PrEP, describes each option in practical terms, and points out where the two regimens differ, being specific about the pros and cons of each (for example, potential bone mineral density loss or renal complications with TDF, and potential weight gain with subsequent metabolic and cardiovascular consequences with TAF).
The TDF versus TAF-based PrEP discussion could also focus on what’s known about the comparative effectiveness of each regimen.
For example, TDF/FTC has been shown to be about 99% effective at preventing infection in men who have sex with men and in transgender women, also about 99% effective in heterosexual women and men, and 74%-84% effective in persons who inject drugs.
In contrast, TAF/FTC has been shown to be about 99% effective in men who have sex with men and transgender women, but it’s efficacy in the other two categories is unknown, Dr. Blackstock said.
The option discussion should include a comparison of the evidence base for each regimen, including the real-world experience with TDF/FTC since 2012, and much more limited experience with TAF/FTC.
Discussing relative costs, although the wholesale costs of the regimens are similar, there is now a generic version of TDF/FTC made by Teva Pharmaceuticals that sells for about $400 less per month than the brand name, which might make the option more acceptable to health insurers.
Decision
The decision talk is about considering the patients preferences and deciding with them what is best.
The clinician could say, for example: “What, from your point of view, matters most to you?”
The clinician should also be willing to allow the patient to defer a decision or to guide them depending on their stated wish, asking something like: “Are you ready to decide, or do you want more time? Do you have more questions? Are there more things we should discuss?
Offering the patient a chance to review the decision can also be a good way to arrive at closure, Dr. Blackstock said.
Robert Goldstein, MD, PhD, an infectious disease specialist and medical director of the transgender health program at Massachusetts General Hospital in Boston, who comoderated the session where Dr. Blackstock presented her talk, said that he also uses a similar approach to the PrEP discussion.
“I use a very patient-centered approach of providing information and talking through the data that are available,” he said.
“I will say that, as patients come to me talking about the transition from TDF to TAF for pre-exposure prophylaxis, I am very clear with them about the limited benefit or no benefit that I see with TAF for pre-exposure prophylaxis, and all of my patients have remained on TDF for pre-exposure prophylaxis,” he added.
No funding source for the presentation was reported. Dr. Blackstock and Dr. Goldstein reported having no conflicts of interest to disclose.

Four-week, 8-week CAB/RPV injections safe, effective in women
according to results from the ATLAS-2M study, presented at the HIV Glasgow 2020 Virtual Conference, held October 5-8. The women also reported high satisfaction with the regimen, compared with daily oral antiretroviral therapy.
Previously reported results had shown that the two-drug combination administered every 8 weeks (600 mg cabotegravir and 900 mg rilpivirine) was noninferior to injections every 4 weeks (400 mg cabotegravir and 600 mg rilpivirine) in adults with HIV during the open-label phase 3b ATLAS-2M trial. Further, the ATLAS and FLAIR phase 3 trials had shown the 4-week administration of the therapy to be noninferior to a daily oral three-drug antiretroviral therapy.
Paul Benn, MBBS, of ViiV Healthcare (which is seeking regulatory approval for CAB/RPV treatment), and his colleagues completed a planned subgroup analysis of women in the ATLAS-2M trial. The primary endpoint was the proportion of intention-to-treat participants with plasma HIV-1 RNA of at least 50 copies/mL with a noninferiority margin of 4% at 48 weeks. The secondary endpoint was the proportion of participants with HIV-1 RNA under 50 copies/mL with a noninferiority margin of 10%.
Among the 280 women enrolled, 137 were randomly assigned to receive injections every 8 weeks, and 143 to receive injections every 4 weeks. A majority of the women (56%) were White, the median age was 44 years, and just over half (53%) were treatment naive with cabotegravir and rilpivirine.
At 48 weeks, 3.6% of women in the 8-week group and 0% of women in the 4-week group had at least 50 copies/mL of HIV-1 RNA. In both arms, 91% of participants had HIV-1 RNA under 50 copies/mL. Plasma concentrations of cabotegravir and rilpivirine were similar between the women and the overall study population.
Confirmed virologic failure occurred in five women, all before week 24. Three of the women were subtype A/A1, and four of them had archived nonnucleoside reverse transcriptase inhibitor (NNRTI) resistance–associated mutations.
There were no significant differences in the safety profile between the groups; 99% of injection site reactions that occurred were mild to moderate and lasted a median 3-4 days. Fewer than 4% of participants discontinued because of adverse events – five women in the 8-week group and five women in the 4-week group. Four women cited injection site reactions as the reason for discontinuation.
Women not previously treated with CAB/RPV reported increased treatment satisfaction on the HIV Treatment Satisfaction Questionnaire, a score of 5.4 in the 8-week group and 3.9 in the 4-week group. Among those with prior CAB/RPV treatment, 88% preferred the 8-weekly injections, 8% preferred the 4-weekly injections, and 2% preferred oral dosing.
Long-acting CAB/RPV is an investigational formulation. In December 2019, the Food and Drug Administration denied approval to the formulation on the basis of manufacturing and chemistry concerns, according to a company press release.

Social factors predicted peripartum depressive symptoms in Black women with HIV
Women with high-risk pregnancies because of chronic conditions are at increased risk for developing postpartum depression, and HIV may be one such risk. However, risk factors for women living with HIV, particularly Black women, have not been well studied, wrote Emmanuela Nneamaka Ojukwu of the University of Miami School of Nursing, and colleagues.
Data suggest that as many as half of cases of postpartum depression (PPD) begin before delivery, the researchers noted. “Therefore, for this study, the symptoms of both PND (prenatal depression) and PPD have been classified in what we have termed peripartum depressive symptoms (PDS),” and defined as depressive symptoms during pregnancy and within 1 year postpartum, they said.
In a study published in the Archives of Psychiatric Nursing, the researchers conducted a secondary analysis of 143 Black women living with HIV seen at specialty prenatal and women’s health clinics in Miami.
Overall, 81 women (57%) reported either perinatal or postpartum depressive symptoms, or both. “Some of the symptoms prevalent among women in our study included restlessness, depressed mood, apathy, guilt, hopelessness, and social isolation,” the researchers said.
Social factors show significant impact
In a multivariate analysis, low income, intimate partner violence, and childcare burden were significant predictors of PDS (P less than .05). Women who reported intimate partner violence or abuse were 6.5 times more likely to experience PDS than were women who did not report abuse, and women with a childcare burden involving two children were 4.6 times more likely to experience PDS than were women with no childcare burden or only one child needing child care.
The average age of the women studied was 29 years, and 59% were above the federal poverty level. Nearly two-thirds (62%) were Black and 38% were Haitian; 63% were unemployed, 62% had a high school diploma or less, and 59% received care through Medicaid.
The researchers assessed four categories of health: HIV-related, gynecologic, obstetric, and psychosocial. The average viral load among the patients was 22,359 copies/mL at baseline, and they averaged 2.5 medical comorbidities. The most common comorbid conditions were other sexually transmitted infections and blood disorders, followed by cardiovascular and metabolic conditions.
Quantitative studies needed
Larger quantitative studies of Black pregnant women living with HIV are needed to analyze social factors at multiple levels, the researchers said. “To address depression among Black women living with HIV, local and federal governments should enact measures that increase the family income and diminish the prevalence of [intimate partner violence] among these women,” they said.
The study findings were limited by several factors including retrospective design and use of self-reports, as well as the small sample size and lack of generalizability to women living with HIV of other races or from other regions, the researchers noted. However, the results reflect data from previous studies and support the value of early screening and referral to improve well being for Black women living with HIV, as well as the importance of comprehensive medical care, they said.
“Women should be counseled that postpartum physical and psychological changes (and the stresses and demands of caring for a new baby) may make [antiretroviral] adherence more difficult and that additional support may be needed during this period,” the researchers wrote.
The study received no outside funding. The researchers had no financial conflicts to disclose.

Heterosexual men likely to have unmet HIV treatment needs
according to findings presented at the HIV Glasgow 2020 Virtual Meeting. MSM had better overall health outcomes than the other two groups, the study found, suggesting that MSW and women have unmet needs that require providers’ attention.
Chinyere Okoli of ViiV Healthcare Global Medical Affairs in Brentford, England, and her associates administered a Web-based survey about HIV-related perceptions and behaviors to 2,389 adults with HIV in 25 countries. The respondents included 1,018 MSM, 479 MSW, and 696 women.
In high-income countries, MSM respondents had been diagnosed a median 9 years earlier, MSW respondents a median 4 years earlier, and women respondents a median 5 years earlier. In middle-income countries, diagnosis was a median 3 years ago for MSM respondents and a median 6 years for MSW and women respondents.
Rates of suboptimal adherence to antiretroviral therapy (ART) were lowest (15.5%) among MSM, compared with MSW (38.8%) and women (28%). Similarly, viral nonsuppression had occurred in only 10.9% of MSM, whereas it had occurred in 43.2% of MSW and 37.1% of women. A little more than one-third (36.5%) of MSM had suboptimal overall health, whereas 47.2% of MSW and 46.2% of women had suboptimal overall health (P < .05).
A similar percentage of MSM (38%) and women (38.2%) reported polypharmacy; both percentages were significantly lower than for MSW (45.1%; P = .020). Yet MSW were less likely than the other two groups to have comorbidities unrelated to HIV: 46.1%, compared with 64.6% of MSM and 56.7% of women (P < .001).
Although a higher proportion (63%) of MSW than MSM (44%) or women (55%) were receiving a multitablet ART regimen, MSW were least likely to consider the impact of side effects when they began ART and were most likely to experience side effects. Only 45% of MSW prioritized minimizing side effects when they began receiving ART, and more than half (52%) were experiencing side effects with their current regimen.
By contrast, a majority of MSM (60%) prioritized minimizing side effects at ART initiation, and only 35% currently had side effects. Women fell in the middle with 48% considering side effects when starting ART and 49% reporting current side effects.
The proportion of respondents who said ART side effects were affecting their lives was not significantly different: 69% of MSM, 73% of MSW, and 74% of women. However, 56% of MSW reported skipping at least one dose in the past month because of side effects, which was more than twice the percentage of MSM (24%; P < .001). One-third of women (33%) reported skipping at least one dose.
MSW were also least comfortable talking to their health care provider about ART side effects: 55% reported discomfort, compared with 34% of MSM and 43% of women. A high majority of MSW (87.9%) said they experienced barriers to talking to their providers about relevant health concerns. The proportion who reported barriers was lower for MSM (59%) and women (72.7%; P < .001).
The substantial differences between MSM and MSW, which were even greater than those between MSW and women, suggest this population has the greatest amount of unmet needs, the researchers concluded. “Acknowledging these differences when planning/administering care can help narrow disparities,” they wrote.

A little more than one-third (36.5%) of MSM had suboptimal overall health, whereas 47.2% of MSW and 46.2% of women had suboptimal overall health (P < .05).
A similar percentage of MSM (38%) and women (38.2%) reported polypharmacy; both percentages were significantly lower than for MSW (45.1%; P = .020). Yet MSW were less likely than the other two groups to have comorbidities unrelated to HIV: 46.1%, compared with 64.6% of MSM and 56.7% of women (P < .001).
Although a higher proportion (63%) of MSW than MSM (44%) or women (55%) were receiving a multitablet ART regimen, MSW were least likely to consider the impact of side effects when they began ART and were most likely to experience side effects. Only 45% of MSW prioritized minimizing side effects when they began receiving ART, and more than half (52%) were experiencing side effects with their current regimen.
By contrast, a majority of MSM (60%) prioritized minimizing side effects at ART initiation, and only 35% currently had side effects. Women fell in the middle with 48% considering side effects when starting ART and 49% reporting current side effects.
The proportion of respondents who said ART side effects were affecting their lives was not significantly different: 69% of MSM, 73% of MSW, and 74% of women. However, 56% of MSW reported skipping at least one dose in the past month because of side effects, which was more than twice the percentage of MSM (24%; P < .001). One-third of women (33%) reported skipping at least one dose.
MSW were also least comfortable talking to their health care provider about ART side effects: 55% reported discomfort, compared with 34% of MSM and 43% of women. A high majority of MSW (87.9%) said they experienced barriers to talking to their providers about relevant health concerns. The proportion who reported barriers was lower for MSM (59%) and women (72.7%; P < .001).
The substantial differences between MSM and MSW, which were even greater than those between MSW and women, suggest this population has the greatest amount of unmet needs, the researchers concluded. “Acknowledging these differences when planning/administering care can help narrow disparities,” they wrote.

Dual therapy serves as well as triple for most HIV patients
based on a meta-analysis including data from more than 5,000 patients.
Although triple therapy remains the standard of care, the availability of more potent drugs has revived interest in dual and mono therapies, wrote Pisaturo Mariantonietta, MD, of the University of Campania Luigi Vanvitelli, Naples, Italy, and colleagues.
In a study published in Clinical Microbiology and Infection, the researchers identified 14 articles including 5,205 treatment-naive HIV adults. The studies were published between 2008 and 2020; 13 were randomized, controlled trials.
The dual therapies used in the studies included atazanavir/r plus maraviroc; lopinavir/r plus lamivudine; raltegravir plus darunavir/r; lopinavir/r plus tenofovir, raltegravir, efavirenz, or maraviroc; atazanavir/r plus raltegravir and darunavir/r plus maraviroc; and dolutegravir plus lamivudine.
Overall, no significant differences occurred in the primary endpoint of treatment failure across 10 studies between dual therapy and triple therapy patients based on data at 48 weeks (relative risk 1.20). “The rate of treatment failure did not differ among the two groups when stratifying the patients according to the drug used in the dual regimen,” the researchers said.
Low viral load’s link to treatment failure
Among 2,398 patients with a low HIV viral load (less than 100,000 copies/mL), dual therapy patients were significantly more likely to experience treatment failure than were triple therapy patients (RR, 1.47, P = .007). No differences were noted between dual and triple therapy failure among patients with high HIV viral loads at baseline. Patterns were similar at 96 weeks, but only three studies included 96-week data, the researchers said.
The rate of discontinuation because of adverse events was not significantly different between the groups at 48 weeks.
The study findings were limited by several factors, including the use of different regimens in the dual strategies, some of which are no longer in use, as well as there being insufficient data to fully compare outcomes at 96 weeks, and lack of information on cerebrospinal fluid viral load, the researchers noted.
However, the results suggest that dual therapy might be considered for HIV-naive patients with a low viral load, they said.
“Further RCTs that will evaluate the efficacy of antiretroviral regimens in use today among difficult-to-treat populations, such as patients with high viral load, including both intention-to-treat and per-protocol analysis, are needed to address this topic,” they concluded.
Consider range of patient factors when choosing therapies
Conducting the study at this time was important because of the expanding options for treating HIV patients, Donna E. Sweet, MD, an HIV specialist and professor of medicine at the University of Kansas, Wichita, said in an interview.
“We now have two single tablet formulations that are dual rather than triple therapy, and as treaters we are all trying to know when to use them,” she explained.
Dr. Sweet said she was not surprised by the study findings, given that well-conducted, randomized, controlled trials allowed the combination therapies to be approved.
Some of the key challenges to identifying the optimal treatment for HIV patients include factoring in the use of concomitant medications that could lead to drug-drug interactions, noted Dr. Sweet, who serves an editorial advisory board member of Internal Medicine News.
The take-home message for clinicians, in her opinion, is that “less drugs may mean less toxicity, but we don’t want to sacrifice efficacy,” she said. “There may be patients who are better suited than others for two vs. three drugs,” Dr. Sweet emphasized.
The next steps for research on the value of dual vs. triple therapy should include longer term efficacy studies, especially in those with lower CD4 counts and higher viral loads, said Dr. Sweet. In addition to factors such as CD4 counts and viral load, the food requirements of certain ART regimens could affect adherence and therefore a clinician decision to use two drugs rather than three, she noted.
Dr. Sweet disclosed past relationships with ViiV, Gilead, Merck, and Janssen on their speakers bureaus, and current advisory roles with Gilead and ViiV.
The study received no outside funding. Lead author Dr. Mariantonietta and several coauthors disclosed relationships with companies including ViiV Healthcare, AbbVie, Janssen-Cilag and Gilead Science, and Merck Sharp & Dohme, but no conflicts in connection with this study.

FROM CLINICAL MICROBIOLOGY AND INFECTION
Being HIV positive increases risk of death from COVID-19
compared with people without HIV.
A comparison of outcomes of people with HIV to people without HIV who were hospitalized in the United Kingdom with COVID-19 from Jan. 17 to June 4 showed that HIV-positive status was associated with a 63% increased risk of day 28 mortality.
This was especially true for HIV+ patients younger than 70 years of age, said Anna Maria Geretti, MD, PhD, professor of virology and infectious diseases, University of Liverpool, England.
The results are from an analysis of data from the ISARIC World Health Organization (WHO) Clinical Characterisation Protocol (UK) study, and were presented at the HIV Glasgow annual meeting, held virtually this year because of the pandemic.
“We investigated whether HIV status could be important in COVID-19 outcomes because there was anxiety on the part of our patients, and we wanted to gather some evidence-based information in order to help guide them,” Dr. Geretti said in an interview.
“ISARIC is an international protocol and the UK is one of the nations participating. We applied for access to its very large database, which connects data from all patients who are hospitalized with either known or suspected COVID-19. We wanted to see specifically how the presentation and outcomes of patients with HIV compared with the rest of the population without HIV. It afforded us an ideal opportunity to start to answer this question, and this is our first analysis in what will be an ongoing process. Importantly, we showed that there is a need to really look more carefully at the population with HIV,” she said.
Out of a total of 47,539 patients in the database, 115 (0.24%) had confirmed HIV-positive status, and 103 of those 115, or 89.6%, had a record of being on antiretroviral therapy.
On admission, the patients with HIV were younger, with a median age of 55 compared with 74 for patients without HIV (P < .001). They also had a higher prevalence of obesity, moderate to severe liver disease, higher lymphocyte counts and C-reactive protein, as well as more systemic symptoms.
There were no differences in respiratory rate, need for oxygen, or prevalence of chest infiltrates.
The cumulative incidence of mortality at day 28 was 25.2% in HIV-positive patients compared with 32.1% in HIV-negative patients (P = .12).
But when the researchers looked more closely, they noticed that the mortality rate was actually higher in younger HIV+ patients compared with HIV-negative patients.
Stratified by age, 28-day mortality was significantly higher in HIV+ patients aged <50 years (P =.004); and those aged 50 to 59 years (P = .05).
“So below the age of 70, the risk of mortality was double in people with HIV. The people with HIV who died often had diabetes with complications and also more frequent obesity, but this was not the only explanation,” Dr. Geretti said. “There is something to do with the HIV status per se.”
Next steps will be to expand the data set and repeat the analysis with an additional 100 patients “at least” she said.
The researchers also hope to zero in on what about being HIV+ is increasing the mortality risk from COVID-19.
“Right now we need greater numbers and we hope that the research community will be stimulated to take a closer look at this information, and merge other data so that we can strengthen confidence in the data and tease out what factors are causing this increased risk for mortality,” Dr. Geretti said.
She also emphasized that all patients admitted to hospital with COVID-19 should be asked about their HIV status.
“It is important that the HIV status be recorded if we want to increase our ability to understand how HIV impacts survival,” she stressed. “In our experience we found that most of the hospital records were not doing that. Since HIV+ patients seem to be at increased risk, HIV status should be factored into the clinical management. Ask patients if they are HIV+, and if it is not known, then do a test. That would be good practice.”
Dr. Geretti reported no relevant financial relationships. The work was supported by grants from the National Institute of Health Research, the Medical Research Council, the Wellcome Trust, the Department for International Development, and the Bill and Melinda Gates Foundation.

Switch to integrase inhibitor regimen safe and effective
data from a randomized trial indicate.
Among 212 women with successful HIV virologic suppression following 48 weeks of treatment with ritonavir-boosted atazanavir plus tenofovir disoproxil fumarate (ATV/r +TDF), among those who were switched to continued therapy with an integrase inhibitor–based regimen of elvitegravir/cobicistat/emtricitabine and tenofovir alafenamide (E/C/F/TAF), mean increases in lumbar spine bone mineral density (BMD) were greater and renal function was improved compared with patients who were maintained with ATV/r + TDF, reported Monica Thormann, MD, from Salvador B. Gautier Hospital in Santo Domingo, Dominican Republic, and colleagues at the HIV Glasgow drug therapy meeting, which was held online in 2020.
Although the E/C/F/TAF regimen was associated with a significantly greater increase in lipids, there was no significant change in the total cholesterol to high-density lipoprotein (HDL) cholesterol ratio.
The patients in the study had previously participated in a blinded randomized trial comparing the integrase inhibitor combination plus TDF with ATV/r + TDF in treatment-naive women.
In the current study, patients were randomly assigned in a 3:1 ratio to maintenance with either E/C/F/TAF (159 patients) or ATV/r + TDF (53 patients).
Forty-eight weeks after the switch, virologic suppression (to fewer than 50 copies/mL) was maintained among 94.3% of those on the integrase inhibitor–based regimen, compared with 86.8% of those on the protease inhibitor–based regimen. Virologic failure was seen in 1.9% of those on the integrase inhibitor–based regimen and in 3.8% of those on the protease inhibitor–based regimen.
In addition, virologic suppression below 20 c/mL at week 48 was more common among women maintained on E/C/F/TAF, at 84.9% vs 71.7% (P = .041). No treatment-emergent resistance was seen with either regimen.
As noted, there were higher mean percentage increases in BMD in the E/C/F/TAF group for both total hip and lumbar spine, but only the latter measure improved significantly in comparison with patients treated with ATV/r + TDF (2.82% vs 0%, P < .001).
Markers of renal tubule damage, including the beta-2 microglobulin to creatinine ratio and the rentinol-binding protein to creatinine ratio, were significantly improved with the integrase inhibitor regimen.
Increases in total cholesterol, LDL cholesterol, and HDL cholesterol were 27 vs 5 mg/dL, 16 vs 8 mg/dL, and 5 vs 0 mg/dL in each case comparing the integrase inhibitor–based regimen to the protease inhibitor–based regimen. All of those comparisons were statistically significant.
As noted, however, the total cholesterol to HDL cholesterol ratio was not significantly different between the treatment arms. The rate or initiation of lipid-modifying agents was 1.3% in the E/C/F/TAF group vs 0 in the ATV/r + TDF group, but this difference was not statistically significant.
“These data demonstrate that women who switch to an integrase inhibitor + TAF‐based regimen maintain high levels of virologic suppression with improvement in BMD and renal function biomarkers, as compared with those remaining on their ritonavir boosted atazanavir + TDF‐based regimen,” the authors wrote.

As noted, there were higher mean percentage increases in BMD in the E/C/F/TAF group for both total hip and lumbar spine, but only the latter measure improved significantly in comparison with patients treated with ATV/r + TDF (2.82% vs 0%, P < .001).
Markers of renal tubule damage, including the beta-2 microglobulin to creatinine ratio and the rentinol-binding protein to creatinine ratio, were significantly improved with the integrase inhibitor regimen.
Increases in total cholesterol, LDL cholesterol, and HDL cholesterol were 27 vs 5 mg/dL, 16 vs 8 mg/dL, and 5 vs 0 mg/dL in each case comparing the integrase inhibitor–based regimen to the protease inhibitor–based regimen. All of those comparisons were statistically significant.
As noted, however, the total cholesterol to HDL cholesterol ratio was not significantly different between the treatment arms. The rate or initiation of lipid-modifying agents was 1.3% in the E/C/F/TAF group vs 0 in the ATV/r + TDF group, but this difference was not statistically significant.
“These data demonstrate that women who switch to an integrase inhibitor + TAF‐based regimen maintain high levels of virologic suppression with improvement in BMD and renal function biomarkers, as compared with those remaining on their ritonavir boosted atazanavir + TDF‐based regimen,” the authors wrote.

data from a randomized trial indicate.
Among 212 women with successful HIV virologic suppression following 48 weeks of treatment with ritonavir-boosted atazanavir plus tenofovir disoproxil fumarate (ATV/r +TDF), among those who were switched to continued therapy with an integrase inhibitor–based regimen of elvitegravir/cobicistat/emtricitabine and tenofovir alafenamide (E/C/F/TAF), mean increases in lumbar spine bone mineral density (BMD) were greater and renal function was improved compared with patients who were maintained with ATV/r + TDF, reported Monica Thormann, MD, from Salvador B. Gautier Hospital in Santo Domingo, Dominican Republic, and colleagues at the HIV Glasgow drug therapy meeting, which was held online in 2020.
Although the E/C/F/TAF regimen was associated with a significantly greater increase in lipids, there was no significant change in the total cholesterol to high-density lipoprotein (HDL) cholesterol ratio.
The patients in the study had previously participated in a blinded randomized trial comparing the integrase inhibitor combination plus TDF with ATV/r + TDF in treatment-naive women.
In the current study, patients were randomly assigned in a 3:1 ratio to maintenance with either E/C/F/TAF (159 patients) or ATV/r + TDF (53 patients).
Forty-eight weeks after the switch, virologic suppression (to fewer than 50 copies/mL) was maintained among 94.3% of those on the integrase inhibitor–based regimen, compared with 86.8% of those on the protease inhibitor–based regimen. Virologic failure was seen in 1.9% of those on the integrase inhibitor–based regimen and in 3.8% of those on the protease inhibitor–based regimen.
In addition, virologic suppression below 20 c/mL at week 48 was more common among women maintained on E/C/F/TAF, at 84.9% vs 71.7% (P = .041). No treatment-emergent resistance was seen with either regimen.

Islatravir + doravirine maintains HIV viral suppression
according to new data.
ISL is a first-in-class nucleoside reverse transcriptase translocation inhibitor (NRTTI), Jean-Michel Molina, MD, PhD, of Saint‐Louis and Lariboisière Hospitals in Paris, explained at the annual HIV drug therapy meeting in Glasgow, Scotland. The randomized, double-blind, dose‐ranging trial compared ISL+DOR to a fixed‐dose combination of DOR, lamivudine, and tenofovir disoproxil fumarate (DOR/3TC/TDF) daily in 121 patients.
Patients in the ISL+DOR group initially received 0.25, 0.75, or 2.25 mg of ISL along with 100 mg of DOR and 200 mg of 3TC. Beginning at week 20, participants achieving HIV viral loads of 50 copies/mL or less discontinued 3TC but continued on their assigned dose of ISL+DOR for at least 24 weeks. At that point the investigators noted a greater number of discontinuations in the 2.25-mg group and settled on the 0.75-mg ISL dose. All patients in the ISL group were transitioned to that dose between weeks 60 and 72.
At week 96, 81.1% of the patients in the combined ISL group maintained viral loads <50 copies/mL, comparable to the 80.6% of those in the DOR/3TC/TDF group.
ISL+DOR appeared to be “well tolerated,” the investigators noted. They found drug-related adverse events in 7.8% of the patients in the ISL+DOR group compared with 22.6% of patients in the DOR/3TC/TDF group. In addition, among the 90 patients in the ISL+DOR group, no more than 5% of participants experienced any specific drug-related adverse event.

Promising Trends Seen in AIDS-Associated NHL
Prognoses for patients with AIDS-associated, non-Hodgkin lymphomas (AIDS-NHLs) have improved dramatically as HIV/AIDS has become easier to treat, and “we’re actually seeing patients with long-term remissions that are translating to cure,” a hematologist told colleagues at the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO).
“Even those with low CD4 counts initially have more chance of survival compared to the historic patients in the pre-HAART [highly active antiretroviral therapy] era,” explained Erin Reid, MD, MS, of the University of California at San Diego Moores Cancer Center. “They’re seeing complete-response rates and overall-survival rates that are nearly matching what we’re seeing in the non-HIV lymphoma cases. And aggressive infection prophylaxis has seemed to mitigate some of the infectious complications.”
Still, Reid said, a severe form of AIDS-NHL continues to have very poor outcomes, although specific regimens appear to be brightening the picture somewhat.
According to Dr. Reid, AIDS-NHLs are the most common malignancy in the HIV-positive population, and patients with these cancers are more likely to have aggressive lymphomas. These patients are also more likely to have lymphomas associated with Epstein-Barr virus—40 to 80%, depending on the subtype of lymphoma—and Kaposi sarcoma-associated herpesvirus (also known as human herpesvirus-8, or HHV8).
“These viruses are driving these cancers, and it begs the question of whether there’s something we can do to target these viruses within these cancer cells in a way that’s therapeutic,” she said.
Compared with the non-HIV population, patients with AIDS-NHL “are much more likely to present with advanced stage, extranodal disease and central nervous system involvement,” she said.
HAART Benefits
It’s become clear that HIV control via HAART has benefits in terms of higher tolerance of chemotherapy doses—“we’re able to use more full or traditional dose regimens”—and perhaps cancer suppression too, she said. A 2013 meta-analysis “favored concurrent therapy with chemotherapy [and HAART]. This has become our recommended standard of care for virtually all cases, except the very rare ones where you cannot find a regimen that is compatible from a PK [pharmacokinetics] standpoint.”
Reid also noted that the HAART era has changed the role of CD4 counts in AIDS-NHLs. “While CD4 count still has some predictive value, its impact on mortality appears attenuated,” she said.
EPOCH Treatment
With regard to treatment, she emphasized the importance of HAART: “We would recommend concurrent HAART whenever possible with chemotherapy, or start it immediately afterward.”
Aggressive infection prophylaxis also is recommended through granulocyte colony-stimulating factor and agents to target threats from pneumocystis jiroveci pneumonia, gram negative rods, and varicella-zoster virus. “I’ve moved away from fungal prophylaxis over the years, only dealing with it if there’s a known fungal infection,” she said.
As for treatment of AIDS-NHL, Reid Suggested that research supports the EPOCH regimen --etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin. However, “we still need strategies for refractory and relapsed disease,” she said.
Reid noted that she has started to see more plasmablastic cases, although her experience is anecdotal. Plasmablastic lymphoma is much more common in the HIV-positive setting, she said.
Lifespans are poor for these patients, with many failing to live for a year. But research hints that the prognosis in AIDS-NHL patients on HAART may actually be better than in the non-HIV population, she said.
A trial published in September 2020, in fact, reports that 87% of 15 patients with AIDS-associated plasmablastic lymphoma survived for at least one year on the EPOCH regimen. Overall, the study found that “people with a collection of HIV-associated lymphomas were doing well overall with the EPOCH backbone,” Reid explained.
Reid reported no relevant disclosures.
