Clin Infect Dis 2021; 71:1300-1305.

Abstract
BACKGROUND Women are underrepresented in human immunodeficiency virus (HIV) research in the United States. To determine if women screening for HIV clinical trials enrolled at lower rates than men, we performed a retrospective, cross-trial analysis. METHODS We conducted an analysis of screening and enrollment during 2003-2013 to 31 clinical trials at 99 AIDS Clinical Trials Group network research sites in the United States. Random-effects meta regression estimated whether sex differences in not enrolling ("screen out") varied by various individual, trial, or site characteristics. RESULTS Of 10 744 persons screened, 18.9% were women. The percentages of women and men who screened out were 27.9% and 26.5%, respectively (P = .19); this small difference did not significantly vary by race, ethnicity, or age group. Most common reasons for screening out were not meeting eligibility criteria (30-35%) and opting out (23%), and these did not differ by sex. Trial and research site characteristics associated with variable screen-out by sex included HIV research domain and type of hemoglobin eligibility criterion, but individual associations did not persist after adjustment for multiple testing. CONCLUSIONS In the absence of evidence of significantly higher trial screen-out for women, approaching more women to screen may increase female representation in HIV trials.

Enhanced immunovirological response in women compared to men after antiretroviral therapy initiation during acute and early HIV-1 infection: results from a longitudinal study in the French ANRS Primo cohort. J Int AIDS Soc 2020; 23:e25485. [PMID: 32333726 PMCID: PMC7183251 DOI: 10.1002/jia2.25485] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2019] [Revised: 12/05/2019] [Accepted: 03/04/2020] [Indexed: 01/03/2023] Open
Abstract
Introduction Previous studies have reported better immunovirological characteristics in women compared with men after HIV seroconversion. We investigated whether differences persisted under long‐term antiretroviral therapy (ART) in individuals treated since acute and early HIV‐1 infection (AHI). Methods Data were obtained for 262 women and 1783 men enrolled between 1996 and 2017 in the French multicentre ANRS PRIMO cohort. We modelled the viral response, long‐term immune recovery and HIV DNA decay in the 143 women and 1126 men who initiated ART within the first three months of infection. Results The participants were mostly white. The mean age was 37 years at AHI diagnosis. Pre‐ART viral loads were lower in women than men, 5.2 and 5.6 log10 copies/mL (p = 0.001). After ART initiation, women more rapidly achieved viral suppression than men (adjusted hazard ratio: 1.33, 95% confidence interval 1.09 to 1.69). They also experienced a faster increase in CD4+ T‐cell count and CD4:CD8 ratio during the first months of treatment. Sex‐related differences in CD4+ T‐cell counts were more pronounced with increasing age. This led to a sustained mean difference of 99 to 168 CD4+ T‐cells/µL depending on age between women and men at 150 months of ART. Moreover, CD4:CD8 ratio of women was higher than that of men by 0.31, at 150 months of ART. There was no statistically significant difference between sexes for the levels of HIV DNA over time (mean estimate at the last modelling point: 1.9 log10 copies/106 PBMCs after 70 months of ART for both sexes). Conclusions The high level of immune recovery and decrease in total HIV DNA levels achieved after ART initiation during AHI reinforce the importance of early diagnosis of HIV infection and immediate ART initiation. The immunological benefit of being female increased throughout prolonged ART duration, which may give women additional protection from adverse clinical events and premature ageing.

Very high baseline HIV viremia impairs efficacy of non-nucleoside reverse transcriptase inhibitor-based ART: a long-term observation in treatment-naïve patients. Infect Dis Poverty 2020; 9:75. [PMID: 32571409 PMCID: PMC7310120 DOI: 10.1186/s40249-020-00700-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Accepted: 06/15/2020] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND It is not completely clear whether a very high pre-therapy viral load (≥ 500 000 copies/ml) can impair the virological response. The aim of this study was to examine the influence of very high baseline HIV-RNA levels on long-term virological responses under one type of regimen. METHODS A retrospective study was performed based on data from two multicenter cohorts in China from January to November 2009, and from May 2013 to December 2015. Untreated HIV infected adults between 18 and 65 years old were recruited before receiving non-nucleoside reverse transcriptase inhibitor-based regimen. All patients had baseline HIV-RNA levels over 500 copies/ml, good adherence, and were followed for at least 24 weeks. Virological suppression was defined as the first HIV-RNA < 50 copies/ml. Virological failure was defined as any of incomplete viral suppression (HIV-RNA ≥ 200 copies/ml without virological suppression within 24 weeks of treatment) and viral rebound (confirmed HIV-RNA level ≥ 50 copies/ml after virological suppression). Chi-square test, Kaplan-Meier analysis, Cox proportional hazards model and Logistic regression were used to compare virological response between each pretreated viral load stratum. RESULTS A total of 758 treatment-naïve HIV patients in China were enlisted. Median follow-up time (IQR) was 144 (108-276) weeks. By week 48, rates of virological suppression in three groups (< 100 000, 100 000-500 000 and ≥ 500 000 copies/ml) were 94.1, 85.0, and 63.8%, respectively (P < 0.001). Very high baseline HIV viremia over 500 000 copies/ml were found to be associated with delayed virological suppression (≥ 500 000 vs < 100 000, adjusted relative hazard = 0.455, 95% CI: 0.32-0.65; P < 0.001) as well as incomplete viral suppression (≥ 500 000 vs < 100 000, adjusted odds ratio [aOR] = 6.084, 95% CI: 2.761-13.407; P < 0.001) and viral rebound (≥ 50 000 vs < 100 000, aOR = 3.671, 95% CI: 1.009-13.355, P = 0.048). CONCLUSIONS Very high levels of pre-treatment HIV-RNA were related with delayed efficacy of NNRTI-based ART and increased risk of treatment failure. More potent initial regimens should be considered for those with this clinical character.

Abstract
PURPOSE OF REVIEW This review will outline the multilevel effects of biological sex on HIV acquisition, pathogenesis, treatment response, and prospects for cure. Potential mechanisms will be discussed along with future research directions. RECENT FINDINGS HIV acquisition risk is modified by sex hormones and the vaginal microbiome, with the latter acting through both inflammation and local metabolism of pre-exposure prophylaxis drugs. Female sex associates with enhanced risk for non-AIDS morbidities including cardiovascular and cerebrovascular disease, suggesting different inflammatory profiles in men and women. Data from research on HIV cure points to sex differences in viral reservoir dynamics and a direct role for sex hormones in latency maintenance. Biological sex remains an important variable in determining the risk of HIV infection and subsequent viral pathogenesis, and emerging data suggest sex differences relevant to curative interventions. Recruitment of women in HIV clinical research is a pathway to both optimize care for women and to identify novel therapeutics for use in both men and women.
