Perceived intentional transmission of HIV infection, sustained viral suppression and psychosocial outcomes among men who have sex with men living with HIV: a cross-sectional assessment.

ABSTRACT: OBJECTIVE:HIV continues to be a global and national public health challenge, and men who have sex with men (MSM) are disproportionately affected in the USA. Transmission of HIV is intentional if the person living with HIV knows about his/her serostatus, acts with the intention to and actually transmits HIV. Research on intentional transmission of HIV infections is lacking, and the relationships between perceived intentional transmission, viral suppression and psychosocial outcomes have not been assessed. The objective of this study was to investigate the association between perceived intentional transmission of HIV, sustained viral suppression and psychosocial outcomes. METHODS:Data were obtained from 338 MSM living with HIV who participated in a disclosure intervention study. Logistic and linear regression models were used to assess the associations between perceived intentional transmission and viral suppression, condomless anal intercourse in the past 30 days, being at risk for clinical depression, substance use, self-efficacies for condom use, HIV disclosure and negotiation of safer sex practices, and sexual compulsivity. RESULTS:44% of the study population reported perceiving intentional HIV transmission. After adjusting for sociodemographic characteristics, men who thought that they were infected intentionally had 69% higher odds (adjusted OR: 1.69; 95%?CI 1.01 to 2.83) of being at risk for clinical depression, and on average, scored approximately 3 points and 4 points higher on depressive symptoms and sexual compulsivity, respectively (adjusted ?: 3.29; 95%?CI 0.42 to 6.15; adjusted ?: 3.74; 95%?CI 1.32 to 6.17) compared with men who did not think that they were intentionally infected. After adjusting for confounders, there was no statistically significant association between perceived intentional transmission and viral suppression. CONCLUSIONS:Intervention programmes for MSM living with HIV who thought they were infected intentionally are warranted and should aim to attenuate depressive symptoms and sexual compulsivity.

Project description:BACKGROUND:HIV viral suppression is associated with health benefits for people living with HIV and a decreased risk of HIV transmission to others. The objective was to identify demographic, psychosocial, provider and neighborhood factors associated with sustained viral suppression among gay, bisexual, and other men who have sex with men. METHODS:Data from adult men who have sex with men (MSM) enrolled in the Miami-Dade County Ryan White Program (RWP) before 2017 were used. Sustained viral suppression was defined as having an HIV viral load <?200 copies/ml in all viral load tests in 2017. Three-level (individual, medical case management site, and neighborhood) cross-classified mixed-effect models were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for sustained viral suppression. RESULTS:Of 3386 MSM, 90.8% were racial/ethnic minorities, and 84.4% achieved sustained viral suppression. The odds of achieving sustained viral suppression was lower for 18-24 and 25-34?year-old MSM compared with 35-49?year-old MSM, and for non-Latino Black MSM compared with White MSM. Those not enrolled in the Affordable Care Act, and those with current AIDS symptoms and a history of AIDS had lower odds of achieving sustained viral suppression. Psychosocial factors significantly associated with lower odds of sustained viral suppression included drug/alcohol use, mental health symptoms, homelessness, and transportation to appointment needs. Individuals with an HIV physician who serves a larger volume of RWP clients had greater odds of sustained viral suppression. Neighborhood factors were not associated with sustained viral suppression. CONCLUSION:Despite access to treatment, age and racial disparities in sustained viral suppression exist among MSM living with HIV. Addressing substance use, mental health, and social services' needs may improve the ability of MSM to sustain viral suppression long-term. Furthermore, physician characteristics may be associated with HIV outcomes and should be explored further.

Project description:BackgroundYunnan has the greatest share of reported human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) cases in China. In recent years, HIV prevalence and incidence remained stubbornly high in men who have sex with men (MSM). To follow the dynamics of the HIV-1 epidemic among MSM, HIV-1 genetic characteristics and genetic transmission networks were investigated.MethodsBlood samples from 190 newly diagnosed HIV-1 cases among MSM were continuously collected at fixed sites from January 2013 to December 2015 in Kunming City, Yunnan Province. Partial gag, pol and env genes were sequenced and used for phylogenetic and genotypic drug resistance analyses. The genetic characteristics of the predominant HIV-1 strains were analyzed by the Bayesian Markov Chain Monte Carlo (MCMC) method. The genetic transmission networks were identified with a genetic distance of 0.03 substitutions/site and 90% bootstrap support.ResultsAmong the 190 HIV-1 positive MSM reported during 2013-2105, various genotypes were identified, including CRF01_AE (45.3%), CRF07_BC (35.8%), unique recombinant forms (URFs) (11.6%), CRF08_BC (3.2%), CRF55_01B (2.1%), subtype B (1.6%) and CRF59_01B (0.5%). The effective population sizes (EPS) for CRF01_AE and CRF07_BC increased exponentially from approximately 2001-2010 and 2005-2009, respectively. Genetic transmission networks were constructed with 308 pol sequences from MSM diagnosed during 2010-2015. Of the 308 MSM, 109 (35.4%) were identified in 38 distinct clusters. Having multiple male partners was associated with a high probability of identification in the genetic transmission networks. Of the 38 clusters, 27 (71.1%) contained individuals diagnosed in different years. Of the 109 individuals in the networks, 26 (23.9%) had ≥2 potential transmission partners (≥2 links). The proportion of MSM with ≥2 links was higher among those diagnosed from 2010-2012. The constituent ratios of their potential transmission partners by areas showed no significant difference among MSM from Kunming, other cities in Yunnan and other provinces. Additionally, surveillance drug resistance mutations (SDRMs) were identified in 5% of individuals.ConclusionThis study revealed the various HIV-a genotypes circulating among MSM in Kunming. MSM with more partners were more easily detected in transmission networks, and early-diagnosed MSM remained active in transmission networks. These findings suggested that the routine interventions should be combined with HIV testing and linkage to care and early antiretroviral therapy among HIV-positive MSM.
