Introduction Erectile dysfunction is common in HIV-positive men who have sex with men (MSM). A standardized scale is needed to assess erectile function in clinical practice and research studies. Aim The International Index of Erectile Function (IIEF) is a widely accepted tool for assessing erectile function designed for heterosexual men. We modified the tool for MSM. We present an analysis of internal consistency of the questionnaire in an HIV-positive cohort. Methods The adapted questionnaire included modified questions within each of the five domains of the IIEF: (i) erectile function, (ii) intercourse satisfaction, (iii) orgasmic function, (iv) sexual desire, and (v) overall satisfaction with sex. MSM at seven European HIV treatment centers completed the questionnaire. Main Outcome Measures Responses were analyzed for internal consistency using standardized Cronbach’s alpha values within each of the five domains. A factor analysis was performed to confirm the domain structure of the questionnaire. Results Data from 486 MSM were analyzed. The factor analysis supported the domain structure described. Questions about erectile function, orgasmic function, and sexual desire performed well, with Cronbach’s alpha values of 0.82, 0.83, and 0.89, respectively. Questions concerning intercourse satisfaction were less consistent (Cronbach’s alpha 0.55) because frequency of attempts at sexual intercourse did not correlate with other responses. Responses about satisfaction with sex with a regular partner diverged from satisfaction with overall sex life. Frequency of morning erections diverged from other aspects of erectile function, whereas erections with masturbation correlated better. Conclusions Internal consistency was high overall. This tool is suitable for HIV-positive MSM and can be used in screening, research, and monitoring treatment response.

Studies have shown more erectile dysfunction (ED) in men living with HIV (MLHIV), relative to age matched HIV-negative men. Erection enhancing medication (EEM) is more frequently used by HIV-positive men than in the general male population. Increased sexually transmitted infection has been described in HIV-positive men with ED using EEM. This study investigated the use of EEM and party drugs (methyleendioxymethamfetamine (XTC), gammahydroxybutyrate (GHB) "fluid XTC" and alkyl nitrites "poppers") among MLHIV. Self-administered questionnaires were distributed consecutively to all patients attending 17 European HIV treatment centers. The sample included 1118 HIV-positive men, among whom 74.5% men having sex with men (MSM). The use of EEM was more frequent in MSM than in heterosexual men (odds ratio (OR) 3.33, p<0.001) and was associated with increased sexual risk behavior (OR 3.27, p<0.001). Nonmedically indicated use of EEM was linked to increased use of party drugs (OR 2.30, p=0.01). Physicians taking care of MLHIV need to be aware of the high prevalence of (nonmedical) use of EEM and party drugs. Medical provision of EEM should be combined with a discussion on safer sex behavior and the risk related to concomitant use of party drugs and illegal EEM.

IntroductionSubstantial disparities in care outcomes exist between different subgroups of adolescents and youths living with HIV (AYLHIV). Understanding variation in individual and health facility characteristics could be key to identifying targets for interventions to reduce these disparities. We modelled variation in AYLHIV retention in care and viral suppression, and quantified the extent to which individual and facility characteristics account for observed variations.MethodsWe included 1170 young adolescents (10–14 years), 3206 older adolescents (15–19 years) and 9151 young adults (20–24 years) who were initiated on antiretroviral therapy (ART) between January 2015 and December 2017 across 124 healthcare facilities in Nigeria. For each age group, we used multilevel modelling to partition observed variation of main outcomes (retention in care and viral suppression at 12 months after ART initiation) by individual (level one) and health facility (level two) characteristics. We used multiple group analysis to compare the effects of individual and facility characteristics across age groups.ResultsFacility characteristics explained most of the observed variance in retention in care in all the age groups, with smaller contributions from individual-level characteristics (14%–22.22% vs 0%–3.84%). For viral suppression, facility characteristics accounted for a higher proportion of variance in young adolescents (15.79%), but not in older adolescents (0%) and young adults (3.45%). Males were more likely to not be retained in care (adjusted OR (aOR)=1.28; p<0.001 young adults) and less likely to achieve viral suppression (aOR=0.69; p<0.05 older adolescent). Increasing facility-level viral load testing reduced the likelihood of non-retention in care, while baseline regimen TDF/3TC/EFV or NVP increased the likelihood of viral suppression.ConclusionsDifferences in characteristics of healthcare facilities accounted for observed disparities in retention in care and, to a lesser extent, disparities in viral suppression. An optimal combination of individual and health services approaches is, therefore, necessary to reduce disparities in the health and well-being of AYLHIV.
