Uptake of PrEP and condom and sexual risk behavior among MSM during the ANRS IPERGAY trial

ABSTRACT The double-blind phase of the randomized ANRS IPERGAY trial, evaluating sexual activity-based oral HIV pre-exposure prophylaxis (PrEP), was conducted among high-risk men who have sex with men (MSM). Results showed an 86% (95% CI: 40–98) relative reduction in HIV incidence among participants with tenofovir disoproxil fumarate–emtricitabine vs. placebo. The present pooled analysis aimed to analyze (i) participants’ adherence to the prescribed treatment and/or condom use during sexual intercourse and (ii) sexual behavior during the double-blind phase of the study. Four hundred MSM were enrolled in the trial. Every 2 months they completed online questionnaires collecting sexual behavior and PrEP adherence data regarding their most recent sexual intercourse. A total of 2232 questionnaires (M0–M24) were analyzed. Changes over time were evaluated using a mixed model accounting for multiple measures. Irrespective of sexual partner and practice type, on average, 42.6% (min: 32.1–max: 45.8%) reported PrEP use only during their most recent episode of sexual intercourse; 29% (22.9–35.6%) reported both PrEP and condom use; 11.7% (7.2–18.9%) reported condom-use only, and 16.7% (10.8–29.6%) reported no PrEP or condom use with no significant change during the study. Scheduled (i.e., correct) PrEP use was reported on average by 59.0% (47.2–68.5%) of those reporting PrEP use during their most recent sexual intercourse. Overall, 70.3% (65.3–79.4%) and 69.3% (58.3–75.4%) of participants reported, respectively, condomless anal and condomless receptive anal intercourse during their most recent sexual encounter without significant change during follow-up. Overall, on average 83.3% (min: 70.4–max: 89.2%) of participants protected themselves by PrEP intake or condom use or both during the trial, and no increase in at-risk sexual practices was observed. None of these indicators showed significant trend during the follow-up, although we found a tendency toward decrease (p = .19) of the median number of sexual partners strengthening the absence of behavioral disinhibition. On-demand PrEP within a comprehensive HIV prevention package could improve prevention in MSM.

Comparison of risk factors in HIV-infected men who have sex with men, coinfected or not with hepatitis C virus (ANRS VESPA2 French cross-sectional national survey)

Objectives HIV-infected men who have sex with men (HIV-MSM) are at high risk of hepatitis C virus (HCV) infection. This study aimed to compare risk factors between HIV-MSM coinfected with HCV and those who are not, in a national representative survey conducted in France. Methods The ANRS VESPA2 survey (April 2011–January 2012) collected sociodemographic and behavioural data (through face-to-face administered questionnaires) as well as medical data (physician questionnaire) among 3022 HIV-infected adults recruited in 73 French HIV hospital departments. We identified behavioural correlates of HCV coinfection among sexually active HIV-MSM who participated in VESPA2 (logistic regression models). Results Ninety-three of the 1037 HIV-MSM of the study population (8.9%) were coinfected with HCV. The following risk factors were independently associated with HCV coinfection, after adjustment for age and time since HIV diagnosis: current or past injecting drug use, having had at least 20 male sexual partners during the previous 12 months, reporting inconsistent condom use during anal sex with casual partners, and attending sex parties. Individuals reporting at least three sexual risk factors were at the highest risk of being coinfected with HCV (OR (95% CI): 22.86 (9.74; 53.62), p<0.0001). Conclusions HIV-MSM reporting several sexual risk factors should be sensitised to risk-reduction behaviours to avoid HCV transmission to sexual partners, and infection or reinfection with HCV.

Health-related quality of life of people living with HIV followed up in hospitals in France: comparing trends and correlates between 2003 and 2011 (ANRS-VESPA and VESPA2 national surveys)

In recent years, France has witnessed both structural changes in the population of people living with HIV and a relative improvement in the social representation of HIV infection. However, potential changes in peoples day-to-day experience with HIV have not been documented. We used data from the national surveys ANRS-VESPA (2003) and VESPA2 (2011) to compare the levels and patterns of correlates of health-related quality of life (HRQL) in adult HIV-infected patients followed up in French hospitals over a period of eight years. Mean physical and mental SF-12 scores were compared (VESPA, n = 2072; and VESPA2, n = 2267) using analysis of variance (ANOVA) F tests. Heckman regression models were then used to identify independent correlates of physical and mental quality of life in the two surveys, while accounting for possible bias due to missing score values. A common set of potential socio-demographic, clinical, behavioral, and psychosocial correlates was tested. Individuals reported a decrease in physical quality of life in VESPA2 compared with VESPA (mean score (standard error): 47.5 (0.2) versus 49.6 (0.2), p < .0001), and better mental HRQL (44.3 (0.3) versus 42.3 (0.3), p < 0.0001). In both surveys, financial difficulties and patient-perceived experience of rejection behaviors by medical staff were independently associated with impaired physical and mental quality of life. Older age and unemployment were independently associated with impaired physical quality of life. Immigrants from Sub-Saharan Africa reported better mental quality of life. Findings show that quality of life levels in adult HIV-infected patients followed up at hospital in France has significantly, yet modestly, changed in recent years. However, the pattern of quality of life correlates has remained relatively stable. The impact of patient–provider relationships on self-reported outcomes is confirmed. Further research is needed to identify potential differences in quality of life correlates in specific subgroups of patients, such as men who have sex with men, women, immigrants, and injecting drug users.

HCV seropositivity in inmates and in the general population: an averaging approach to establish priority prevention interventions

Objectives Despite the fact that a considerable portion of hepatitis C virus (HCV) positive individuals are viraemic, the risk of transmitting HCV to others is context dependent. Prison is a particularly risky environment as HCV prevention tools are often unavailable. Using data from a cross-sectional study conducted in centres for HCV testing in southeastern France, we aimed to compare the patterns of risk factors in HCV-positive inmates with those in the general population. Setting 26 centres for HIV/HCV testing in southeastern France (23 in the general population and 3 in prison). Primary outcome measure HCV seropositivity measured with ELISA test. Methods A propensity score method to ensure that the general and inmate populations could be compared and a multimodel averaging to estimate the degree (strong, weak, none) of the association of a number of specific factors with HCV seropositivity in each group. Results Among the 52 082 participants, HCV infection prevalence was 1.5% and 5.2% in the general (n=46 125) and inmate (n=5957) populations, respectively. In both populations, ‘drug injection without snorting’ and ‘drug injection with snorting’ were very strongly associated with HCV seropositivity. Among inmates, ‘drug snorting alone’ (OR (95% CI) 2.21 (1.39 to 3.52) was also a strong correlate while tattoos, piercings (OR (95% CI) 1.22 (0.92 to 1.61)) and the sharing of toiletry items (OR (95% CI) 1.44 (0.84 to 2.47)) were weak correlates. Conclusions The pattern of risk factors associated with HCV seropositivity is different between the general and prison populations, injection and snorting practices being more prevalent in the latter. Access to prevention measures in prisons is not only a public health issue but also a human right for inmates who deserve equity of care and prevention.

Factors associated with satisfaction with community-based non-medicalized counseling and testing using HIV rapid tests among MSM in France

ABSTRACT The aims of the study were to determine the level of satisfaction of men who have sex with men (MSM) participating in two community-based non-medicalized counseling and testing programs (ANRS-DRAG and ANRS-COM’TEST) offering HIV rapid tests (hereafter CBOffer), and to identify factors associated with satisfaction. Between 2009 and 2011, 436 participants voluntarily benefited from a CBOffer in the two programs. They completed self-administered questionnaires before and after testing. Psychosocial scores were constructed using principal component analyses to reflect the following dimensions: post-test satisfaction, avoidance of at-risk situations as a HIV risk-reduction strategy, and attitudes towards condom use. Logarithmic regression of the post-test satisfaction score was performed on these scores and on other selected explanatory variables, including the variable “self-identification as homosexual or bisexual”. Post-test satisfaction ranged between 90–99 and below 90 for 50% and 25% of the participants, respectively. Post-test satisfaction with the CBOffer was independently associated with self-defined sexuality, meeting place for sexual partners, participants’ attitudes about being HIV-positive, and condom use. The very high level of satisfaction was associated with both personal and socio-behavioral factors. Vulnerable MSM could be targeted better and, accordingly, could use this offer more frequently as a combined prevention tool.

Heterosexual practices of women and men living with HIV attending hospital outpatient services (ANRS-VESPA2 survey): a French comparative study with the general population (CSF survey)

ABSTRACT HAART has improved the well-being of many people living with HIV (PLWH). This study aimed at (i) comparing heterosexual practices between PLWH and the general population by gender, and (ii) identifying factors associated with sexual practices and at-risk behaviors in the two populations. Self-reported data were collected among PLWH attending hospitals (VESPA2 survey; n = 3022) and the general population (CSF survey; n = 10,280). Significant differences between the two samples were corrected for by implementing propensity score matching on both socio-demographic characteristics and sexual behavior in terms of number of partners. Men not reporting heterosexual intercourse were excluded. After matching, 61% of women (out of 707) and 68% of men (out of 709) were sexually active in both populations. PLWH practiced oral sex less than the general population and used condoms more consistently over the previous 12-month period, irrespective of having multiple sexual partners or not. For women living with HIV: those with several sexual partners and those consuming drugs over the previous 12 months were more likely to practice oral sex; those living in a couple for at least 6 years and migrants were less likely to practice anal intercourse. For men living with HIV: those reporting bisexual relationships and those with multiple sexual partners over the previous 12 months were more likely to practice anal heterosexual intercourse; migrants reported less oral sex, irrespective of HIV status. Error term correlations showed that anal intercourse was not linked to condom use for women or men from either population. Our results show that PLWH had a lower rate of heterosexual practices compared with the general population, and used condoms more often, irrespective of the number of sexual partners and strong cultural background (e.g., for Sub-Saharan African women). Further preventive information needs to be disseminated on the risk of infection transmission through heterosexual anal intercourse.

Spontaneous and post-treatment HCV clearance: relationships with health-related quality of life in HIV infection (ANRS-VESPA2 study)

Background: Post-treatment clearance of HCV is associated with improved health-related quality of life (HRQL) in HIV–HCV co-infection. However, the potential differences in HRQL between post-treatment and spontaneous clearers remain poorly documented. Methods: Linear regression models were used to assess the relationships between HCV status and HRQL (PROQOL-HIV scale) in 411 co-infected adults followed-up in French hospitals in 2011 (ANRS-VESPA2 survey). Results: After adjustment for socio-economic and clinical factors, patients previously exposed to HCV treatment showed better physical HRQL and better experience of HIV treatment than treatment-naive HCV-chronic patients. Post-treatment clearers showed better mental HRQL. Spontaneous clearers showed better experience of HIV treatment. Conclusion: Spontaneous and post-treatment HCV clearance may influence different dimensions of HRQL of HIV–HCV co-infected patients. Further studies in real-life settings are needed to document patient-reported outcomes in the era of direct-acting antiviral agents for HCV treatment.

Treatment interruption in HIV-positive patients followed up in Cameroon's antiretroviral treatment programme: individual and health care supply-related factors (ANRS-12288 EVOLCam survey)

Decreasing international financial resources for HIV and increasing numbers of antiretroviral treatment (ART)‐treated patients may jeopardise treatment continuity in low‐income settings. Using data from the EVOLCam ANRS‐12288 survey, this study aimed to document the prevalence of unplanned treatment interruption for more than 2 consecutive days (TI>2d) and investigate the associated individual and health care supply‐related factors within the Cameroonian ART programme.

Larger is not necessarily better! Impact of HIV care unit characteristics on virological success: results from the French national representative ANRS-VESPA2 study.

OBJECTIVES To determine the impact of hospital caseload size on HIV virological success when taking into account individual patient characteristics. METHODS Data from the ANRS-VESPA2 survey representative of people living with HIV in France was used. Analyses were carried out on the 2612 (86.4% out of 3022) individuals receiving antiretroviral (ARV) treatment for at least one year. Outcomes correspond to two definitions of virological success (VS1 and VS2 respectively) and were analyzed under a multi-level modeling framework with a special focus on the effect of the caseload size on VS. RESULTS Structures with caseloads <1700 patients were more likely to have increased the proportion of patients achieving virological success (59% and 81% for VS1 and VS2, respectively) than structures whose caseloads numbered ≥1700 patients. Our results highlight that patients in the 11 largest care units in the sample were exposed to a context where their VS was potentially compromised by care unit characteristics, independently of both their individual characteristics and their own HIV treatment adherence behavior. CONCLUSIONS Our results suggest that - at least in the case of HIV care - in France large care units are not necessarily better. This result serves as an evidence-based warning to public authorities to ensure that health outcomes are guaranteed in an era when the French hospital sector is being substantially restructured.
