Prescriptions of generic antiretroviral drugs in three healthcare centers in the Paris area, France.

In a retrospective study conducted in three hospitals in Paris, generic antiretroviral accounted for 30.2% of all prescriptions. Tenofovir disoproxil/emtricitabine (TDF/FTC) was the most prescribed generic ART (82.3% of generic prescriptions). Generic ART (gART) was more likely to be prescribed to women, to patients less than 50 years, and with recent HIV diagnosis less than 3 years. Physicians prescribed more gART if they were men, older than 55 years or worked at a university teaching hospital.

Brief Report: Incidence and Management of Complex Kidney Situations Among On-Demand and Daily HIV Pre-Exposure Prophylaxis Users.

BACKGROUND: We evaluated complex pre-exposure prophylaxis (PrEP) situations linked to kidney issues in a cohort of on-demand and daily PrEP users. SETTING: We conducted a single-center retrospective cohort study in France including all PrEP users who received a tenofovir disoproxil (TD)-emtricitabine (FTC) prescription between January 1, 2012 and December 31, 2019 with at least 1 creatinine measurement available before and after PrEP initiation. METHODS: A complex kidney situation (CKS) was defined as an estimated glomerular filtration rate (eGFR) <60 mL/minute/1.73m 2 on 2 consecutive measurements. We estimated the incidence of this event, described case management, and identified associated factors using a Cox model. RESULTS: Three thousand one hundred and fourteen individuals were included in this study. Almost all were men (99%) with a median age of 35 years, 25% had an eGFR <90 mL/minute/1.73m 2 at baseline, and 65% used on-demand PrEP. Nine users (0.29%) had a CKS at baseline; 8/9 initiated on-demand PrEP without renal function worsening after a median (interquartile range [IQR]) follow-up time of 14 months (7-31). Thirteen cases of CKS occurred during the follow-up for a 0.25 per 100 person-years incidence (95% confidence interval [CI]: [0.14; 0.45]). On-demand PrEP was used in 7/13 participants with no further episode of confirmed eGFR <60 mL/minute/1.73m 2 after a 17-month median follow-up (IQR 4-18). CKS was associated with an age ≥50 years (hazard ratio [HR] 13, 95% CI: [4-39]) or with a baseline eGFR <90 mL/minute/1.73m 2 (HR 34, 95% CI: [4-261]). 9/22 CKS were linked to high-protein intake for weight training. CONCLUSIONS: CKS were rare in our cohort. On-demand PrEP did not result in subsequent renal function worsening in these few situations.

Updated mortality and causes of death in 2020-2021 in people with HIV: a multicenter study in France.

OBJECTIVE: The aim of this study was to assess updated mortality and causes of death in people with HIV (PWH) in France. DESIGN AND METHODS: We analyzed all deaths in PWH followed up between January 1, 2020, and December 31, 2021, in 11 hospitals in the Paris region. We described the characteristics and causes of death among deceased PWH, and evaluated the incidence of mortality and associated risk factors using a multivariate logistic regression. RESULTS: Of the 12 942 patients followed in 2020--2021, 202 deaths occurred. Mean annual incidence of death [95% confidence interval (95% CI)] was 7.8 per 1000 PWH (6.3-9.5). Forty-seven patients (23%) died from non-AIDS nonviral hepatitis (NANH)-related malignancies, 38 (19%) from non-AIDS infections (including 21 cases of COVID-19), 20 (10%) from AIDS, 19 (9%) from cardiovascular diseases (CVD), 17 (8.4%) from other causes, six (3%) from liver diseases, and five (2.5%) from suicides/violent deaths. The cause of death was unknown in 50 (24.7%) patients. Risks factors for death were age [adjusted odds ratio (aOR) 1.93; 1.66-2.25 by additional decade), AIDS history (2.23; 1.61-3.09), low CD4 + cell count (1.95; 1.36-2.78 for 200-500 cells/µl and 5.76; 3.65-9.08 for ≤200 versus > 500 cells/µl), and viral load more than 50 copies/ml (2.03; 1.33-3.08), both at last visit. CONCLUSION: NANH malignancies remained in 2020-2021 the first cause of death. COVID-19 accounted for more than half of the mortality related to non-AIDS infections over the period. Aging, AIDS history, and a poorer viro-immunological control were associated with death.

Safety and efficacy of switching to elvitegravir, cobicistat, emtricitabine, tenofovir disoproxil fumarate in treatment-experienced people with HIV: a multicenter cohort study.

OBJECTIVES: We assessed the virologic efficacy of switching to co-formulated elvitegravir, cobicistat, emtricitabine, tenofovir disoproxil fumarate (E/C/F/TDF) in patients with controlled HIV infection. METHODS: We conducted a retrospective multicenter observational cohort study including adult patients with controlled HIV-1 infection on any stable antiretroviral (ART) regimen, who switched to E/C/F/TDF. Success was measured by the proportion of patients with plasma viral load < 50 copies/ml at W48 using the FDA snapshot algorithm. We also assessed risk factors associated with virological failure (VF). RESULTS: 382 patients with HIV RNA < 50 copies/mL who switched to E/C/F/TDF were included in the study. Most patients (69.9%) were male, with median age 44 years (IQR 38-51), who had been on ART for a median of 7 years (IQR 4-13). Median CD4 count was 614/mm3 and 24.6% of the patients had a history of previous virological failure. The reasons for switching were simplification (67.0%) and tolerance issues (22.0%). At week 48, 314 (82.0% [95% CI 78.4-86.0]) patients had HIV RNA < 50 copies/mL, 13 (3.5% [95% CI 3.64-8.41]) experienced virological failure. Genotype at failure was available in 6/13 patients with detection of resistance-associated mutations to integrase inhibitors and NRTIs in 5/6 (83.3%) patients. We found no predictive factor associated with virological failure except for a borderline significance with the duration of viral suppression before the switch. Tolerability of E/C/F/TDF was good with 23/382 (6.0%) patients experiencing mild adverse reactions. CONCLUSION: In our cohort, switching well-suppressed patients to E/C/F/TDF resulted in few virologic failures and was well tolerated. However, resistance to integrase inhibitors emerged in patients with virological failure.

Brief Report: Efficacy and Safety of Efavirenz, Raltegravir, and Dolutegravir in HIV-1/TB Coinfection. A Multicenter Retrospective Cohort Study in France.

BACKGROUND: There are limited data comparing the efficacy and safety of raltegravir and dolutegravir to that of efavirenz in HIV-1/tuberculosis (TB) coinfected patients. METHODS: We conducted a 10-year retrospective study in 4 centers in France. We included all HIV-1/tuberculosis coinfected patients starting antiretroviral therapy with a rifampicin-based regimen, with a plasma HIV RNA level (VL) > 1000 copies/mL. The primary endpoint was the proportion of patients with virological success that is, with VL <50 copies/mL at W48 using an Intention-To-Treat analysis, using last-observation-carried-forward to impute missing data. We also assessed antiretroviral therapy safety, analyzing treatment discontinuation for adverse events. RESULTS: Between 2010 and 2020, 117 patients were included. Thirty-nine (33.3%) were treated with raltegravir and 2 nucleoside reverse transcriptase inhibitors (NRTIs), 19 (16.2%) with dolutegravir (and 2 NRTIs) and 59 (50.4%) with efavirenz (and 2 NRTIs). At W48, the primary endpoint was achieved in 24 patients (61.5%) in the raltegravir group, in 12 (63.2%) in the dolutegravir group, and in 41 (69.5%) in the efavirenz group using an Intention-To-Treat analysis ( P = 0.68). Emergence of drug resistance in patients with virological failure, defined as a VL >50 copies/mL, was observed in 3 patients with efavirenz and one patient with raltegravir. Rate of treatment discontinuation for drug-related adverse events was 10.3%, 10.6%, 16.9% for raltegravir, dolutegravir and efavirenz respectively ( P = 0.67). CONCLUSIONS: In this retrospective cohort study, raltegravir and dolutegravir yielded similar efficacy and safety results to efavirenz for the treatment of HIV-1/TB coinfected patients.

Mortality of People Living with HIV in Paris Area from 2011 to 2015.

In high-income countries, causes of death in people living with HIV (PLHIV) have changed. Three French national surveys from 2000 to 2010 showed a decrease in AIDS-related and an increase in non-AIDS-related deaths. Deaths notified in PLHIV followed between January 1, 2011 and December 31, 2015 in 1 of 13 participating hospitals northeast of Paris area were described. Risk factors for death were assessed, using a multivariable logistic regression model. Of 14,403 individuals, 295 died. Median age at death was 52 years (interquartile range = 47-60) and 77% were men. Sixty-seven individuals (23%) died from non-AIDS-defining nonviral hepatitis-related (NaNH) malignancy, 40 (14%) from AIDS, 34 (12%) from cardiovascular disease (CVD), 33 (11%) from non-AIDS infection, 21 (7%) from liver disease, and 12 (4%) from suicide. Men and women born in sub-Saharan Africa had a lower adjusted odds ratio (aOR) of dying than men having sex with men (MSM) born in France (0.70, 95% confidence interval = 0.45-1.09; and 0.45, 0.28-0.73, respectively). Risk factors for death were older age (aOR = 2.26, 1.36-3.77 for 40-49 years and 2.91, 1.75-4.84 for >50 years vs. 18-39 years), male intravenous drug users (IVDU) transmission (2.24, 1.42-3.54 vs. MSM born in France), AIDS (2.75, 2.10-3.59), antiretroviral therapy initiation in earlier periods, time since HIV diagnosis <1 year, low CD4 cell count nadir, hepatitis B virus and/or hepatitis C virus coinfection (1.69, 1.23-2.30), and psychiatric disorders (1.73, 1.27-2.38). Our study confirms the increasing frequency of non-AIDS-related deaths, mainly NaNH malignancies and CVD, in PLHIV, justifying overall and in some specific populations (psychiatric and IVDU) prevention and screening.

Daily or on-demand oral tenofovir disoproxil fumarate/emtricitabine for HIV pre-exposure prophylaxis: experience from a hospital-based clinic in France.

BACKGROUND: On-demand oral tenofovir disoproxil fumarate and emtricitabine (TDF/FTC) has been approved for pre-exposure prophylaxis (PrEP) in MSM in France following the results of clinical studies, but data are limited on real-world experience. DESIGN: A single-center, open-label, prospective cohort study that recruited people at high risk of HIV infection in Paris. METHODS: Participants were enrolled in a single hospital-based outpatient clinic and were proposed to start PrEP with daily or on demand TDF/FTC. At baseline and every 3 months thereafter, patients were tested for HIV and creatinine plasma levels, and data on sexual behavior, other sexually transmitted infections (STIs), and tolerability were collected. RESULTS: From 10 November 2015 to 30 April 2017, 1069 patients were screened and 1049 (98.1%) started PrEP. Median age was 36 years, 99.4% were MSM with a median number of partners of 10, and 793 (75.6%) opted for on demand PrEP. Over 486 person-years of follow-up, four HIV-infections were diagnosed in poorly or nonadherent patients (incidence 0.82/100 person-years). Rate of condomless sex at last intercourse increased from 53.3% at baseline to 79% at month 12 (P < 10), but increase in bacterial STI rates was modest (14.6% at baseline vs. 19.2% at month 12; P < 10). Most adverse events were gastrointestinal and did not lead to PrEP discontinuation. CONCLUSIONS: Most PrEP users were high-risk MSM and opted for on-demand PrEP. PrEP use was associated with a low HIV incidence and a high rate of condomless sex with a modest increase in bacterial STIs.
