No Association Between HLA-B*57:01 and Prevalence and/or Outcome of Progressive Multifocal Leukoencephalopathy in a French Nationwide Human Immunodeficiency Virus Cohort.

Among 34,351 patients living with human immunodeficiency virus with available HLA-B*57:01 included in the Dat'AIDS cohort, 194 patients (0.56%) had a history of progressive multifocal leukoencephalopathy (PML) and 1,746 (5.08%) were carriers of HLA-B*57:01. The frequency of HLA-B*57:01 was similar among patients with history of PML compared with patients without a history of PML (6.19% [95% confidence interval, CI 2.8%-9.6%] vs. 5.08% [95% CI 4.8%-5.3%]; p = .48). Among patients with PML, clinical and biological characteristics at PML diagnosis and the PML outcome were not different according to HLA-B*57:01 status.

Sport and self-esteem in people living with HIV: a cross-sectional study.

BACKGROUND: In the general population, sport activity is associated with better health and better self-esteem. Among people living with HIV (PLHIV), sport activity could also be associated with better self-esteem. The main objective of our study was to assess the association between sport activity and self-esteem among people living with HIV. The secondary objectives were to evaluate the associations between sport activity with fatigue as well as with pain. METHODS: We performed a cross-sectional observational study among PLHIV in our region (Pays de la Loire in France). Each adult seen in routine HIV care was invited to participate in the study. Participants were invited to fill out self-questionnaires about sport activity, self-esteem, fatigue, and pain. The 2 groups of participants with and without sport activity were compared with a T Student test for self-esteem, fatigue, and pain scales. RESULTS: Among the 1160 people included in the study, 47% performed sport activity. The self-esteem score was better in the "sporting group" compared with the "non sporting group" (Rosenberg mean scale 32.7 ± 5.1/40 vs 31.9 ± 5 p = 0.01). The Functional Assessment of Chronic Illness Therapy Fatigue scale showed a lower fatigue in the sporting group than in the non-sporting group (mean total score 125 ± 22 vs 118 ± 24 p < 0.0001). The sporting group had a lower mean pain score (1.1 ± 1.8) than the non sporting group (1.4 ± 1.9 p = 0.004). CONCLUSIONS: Among PLHIV in our region, sport activity was associated with better self-esteem, lower fatigue and lower pain. Sport activity should be included in patient care for people living with HIV.

Measles seroprevalence in human immunodeficiency virus-infected adults born in the era of measles vaccination.

OBJECTIVE: Widespread use of the measles vaccine should lead to the elimination of this disease. Here, we study the seroprevalence of measles in a cohort of adults living with HIV born after the introduction of measles vaccine in France and attempt to identify risk factors for the absence of serum measles antibody. DESIGN: In this multi-centre cross-sectional study, adult outpatients born after 1980 were screened for the presence of measles IgG antibody. Demographic and clinical data were obtained from the standardized electronic medical record system. Univariate and multivariate logistic regressions were performed to identify factors associated with the absence of measles antibodies. RESULTS: Between April 2019 and April 2020, 648 participants were enrolled. The median age was 33 years, 53.6% were born outside of France, and 74% were considered as socially deprived. Plasma HIV RNA was undetectable in 86% of patients. Among 603 evaluable patients, measles serology was positive in 87.2%. Only 81.8% of the patients with documented vaccination tested positive for measles IgG. Younger age was significantly associated with the absence of measles serum antibodies ( P  = 0.004 for each 10-year lower), as was birth in France ( P  < 0.001) and absence of social vulnerability ( P  = 0.04). CONCLUSION: The current study revealed a low seroprevalence of measles compared with that previously reported in France 6 years earlier and to the expected rate to achieve herd immunity. Checking vaccination record should be systematically carried out in patients living with HIV to fill the immunity gaps.

Assessment of drug-drug interaction in an elderly human immunodeficiency virus population: Comparison of 3 expert databases.

AIMS: Polypharmacy increase the risk of drug-drug interactions (DDIs) in the elderly population living with human immunodeficiency virus (HIV). Several expert databases can be used to evaluate DDIs. The aim of the study was to describe actual DDIs between antiretroviral drugs and comedications in an elderly population and to compare grading of the DDIs in 3 databases. METHODS: All treatments of HIV-infected subjects aged 65 years and older were collected in 6 French HIV centres. Summary of Product Characteristic (SPC), French DDI Thesaurus (THES), and Liverpool HIV DDI website (LIV) were used to define each DDI and specific grade. DDIs were classified in yellow flag interaction (undefined grade in SPC and THES or potential weak interaction in LIV), amber flag interaction (to be considered/precaution of use in SPC and THES and potential interaction in LIV) and red flag interaction (not recommended/contraindication in SPC and THES and do not administer/contraindication in LIV). RESULTS: Among 239 subjects included, 60 (25.1%) had at least 1 DDI for a total of 126 DDIs: 23/126 red flag DDIs were identified in 17 patients. All these 23 DDIs were identified in LIV. THES and SPC missed 6 and 1 red flag DDIs, respectively. Seven of 23 red flag DDIs were identified in the 3 databases concomitantly. CONCLUSION: Polypharmacy is frequent in this elderly HIV population leading to DDI in a quarter of the subjects. The discrepancies between databases can be explained by differences in analysis methods. A consensus between databases would be helpful for clinicians.

Pharmacist's role in HIV care in France. Implication for clinical improvement of people living with HIV worldwide.

In France, antiretroviral (ARV) treatment can be dispensed by hospital and/or community pharmacies. Since January 2016, an online patient medication file can be used to optimize dispensing, but medication interviews have not yet been incorporated into this system. To understand both people living with HIV (PLHIV) and their pharmacists' habits and expectations of patient medication file and interviews, two consecutive national surveys were organized. The first one, carried out in October 2016 in care centers, was an anonymous questionnaire for PLHIV. The second one was an online survey for community and hospital pharmacies conducted in February 2017. A total of 1137 PLHIV (68% men, of mean age 50.2 ± 11.5 years, CD4 count 671 ± 354, 90% with undetectable HIV viral load (VL) and 64.2% reporting comorbidities) and 246 pharmacies responded. While the existence of the online medication file is known by 58% of PLHIV, only 40% of pharmacists declare it to be systematically offered. It was offered to 120/694 (17%) PLHIV and 96 (80%) accepted it. Currently, 78 (7%) PLHIV feel well taken care of because they are offered medication interviews, 343/1078 (32%) would like to take advantage of this program, mainly those with a shorter ARV duration (OR ARV duration 0.97 [0.95-0.99]), a VL less often undetectable (OR undetectable VL 0.55 [0.31-0.98]), and those who feel anxious more often (OR anxious 2.38 [1.48-3.84]). These results suggest that better implementation of medication files and interviews will strengthen current clinical pathways.

Tenofovir DF/emtricitabine/rilpivirine as HIV post-exposure prophylaxis: results from a multicentre prospective study.

OBJECTIVES: Since 2016, French guidelines have recommended the single-tablet regimen of tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC)/rilpivirine (RPV) as HIV post-exposure prophylaxis (PEP), but few data support this usage. We evaluated the tolerability, treatment completion and occurrence of HIV seroconversion associated with this combination in occupational and non-occupational PEP. PATIENTS AND METHODS: We conducted an observational, prospective, multicentre, open-label, non-randomized study in five French HIV centres. Adults requiring PEP according to national French guidelines were prescribed TDF/FTC/RPV one pill once a day for 28 days. Clinical and biological tolerability was assessed at week 4; occurrence of HIV seroconversion was evaluated after week 16. RESULTS: From March 2016 to March 2017, 163 courses of PEP were prescribed for 150 sexual exposures (44% heterosexual and 56% MSM) and 13 non-sexual exposures. Five participants stopped PEP after a few days because the source person was HIV uninfected. Of the remaining 158 individuals, 15 (9.5%) were lost to follow-up at week 4, 7 (4.4%) prematurely discontinued PEP [patient's decision/non-adherence (n = 3) or adverse events (gastrointestinal intolerance n = 3, fatigue n = 1)] and 136 (86.1%) completed the 28 day treatment. Overall, 69.6% of participants declared at least one adverse event, mostly of mild to moderate intensity and no serious adverse events or hepatic or renal toxicity occurred. No HIV seroconversion occurred at week 16. CONCLUSIONS: The low rate of premature treatment interruption, the good tolerability and the absence of documented HIV seroconversion support the current French guidelines of a 28 day course of TDF/FTC/RPV for sexual and non-sexual PEP.

Evaluation of residual viremia and quantitation of soluble CD14 in a large cohort of HIV-infected adults on a long-term non-nucleoside reverse transcriptase inhibitor-based regimen.

Beyond virological suppression and immunologic recovery, the objective of long-term antiretroviral therapy is to suppress maximally viremia and to control for persistent immune activation. Non-nucleoside reverse transcriptase inhibitor (NNRTI)-containing regimens are associated with lower residual viremia. The objective of the study was to evaluate the impact of long term NNRTI-containing treatment on residual viremia and on monocyte activation in a cohort of patients infected with HIV-1. To identify factors associated with residual viremia, adult patients infected with HIV on nevirapine or efavirenz-based therapy with viral load <50 copies/ml for >6 months were included. Residual plasma viremia was quantified using an adapted Cobas/Taqman HIV-1 assay. Viral loads with no detected signal were considered as <1 copy/ml. Monocyte activation was evaluated by quantitation of plasma sCD14 by ELISA assay at the time of residual viremia measurement. Logistic regression was used to determine factors associated with residual viremia <1 copy/ml. In this cohort of 421 patients on long-term NNRTI regimen, three quarters had a residual viremia <1 copy/ml. In multivariate analysis, duration of plasma viral load below 50 copies/ml was the only factor associated with residual viremia <1 copy/ml. Soluble CD14 was in the normal range although treatment with nevirapine was associated with a significant lower level of sCD14 compared to efavirenz. Residual viremia <1 copy/ml was frequent in this cohort of patients with long term virological control and confirmed the results of previous studies. Apart from its antiviral effect, nevirapine as well as efavirenz could decrease monocyte activation.

Confirmation of a low α/ß ratio for prostate cancer treated by external beam radiation therapy alone using a post-treatment repeated-measures model for PSA dynamics.

PURPOSE: To estimate the α/ß ratio of prostate cancer treated with external beam radiation only by use of a model of long-term prostate-specific antigen (PSA) dynamics. METHODS AND MATERIALS: Repeated measures of PSA from 5,093 patients from 6 institutions treated for localized prostate cancer by external beam radiation therapy (EBRT) without planned androgen deprivation were analyzed. A biphasic linear mixed model described the post-treatment evolution of PSA, rather than a conventional model of time to biochemical recurrence. The model was adjusted for standard prognostic factors (T stage, initial PSA level, and Gleason score) and cohort-specific effects. The radiation dose fractionation effect was estimated from the long-term rate of rise of PSA level. RESULTS: Adjusted for other factors, total dose of EBRT and sum of squared doses per fraction were associated with long-term rate of change of PSA level (p = 0.0017 and p = 0.0003, respectively), an increase of each being associated with a lower rate of rise. The α/ß ratio was estimated at 1.55 Gy (95% confidence band, 0.46-4.52 Gy). This estimate was robust to adjustment of the linear mixed model. CONCLUSIONS: By analysis of a large EBRT-only cohort along with a method that uses all the repeated measures of PSA after the end of treatment, a low and precise α/ß was estimated. These data support the use of hypofractionation at fractional doses up to 2.8 Gy but cannot presently be assumed to accurately represent higher doses per fraction.
