Rate of HIV Seroconversion Among Seronegative Male Partners Living with HIV Positive Women in Addis Ababa, Ethiopia, 2019: A Retrospective Cohort Study

OBJECTIVE: This study aimed to assess rate of HIV seroconversion and predictors among seronegative male partners living with HIV-positive women in Addis Ababa, Ethiopia, 2019. METHODS: Institutional-based retrospective cohort was used to conduct the study. All eligible 227 sample medical records were used for the study. Kaplan–Meier analysis was used to estimate seroconversion time. Cox proportional-hazard regression was used to identify predictor variables. RESULTS: In this study, 227 seronegative male partners living with HIV-positive women were followed for 60 months retrospectively and 38 (16.7%) seroconversion was observed. The overall seroconversion rate was 6.4 (95%CI: 4.64–8.76) per 100 person-year observation. Time of antiretroviral therapy (ART) initiation, CD4 level, condom use, and having history of pregnancy after being diagnosed as discordant were identified significant predictors of seroconversion. CONCLUSION: The risk of HIV transmission from seropositive partner to seronegative partner in a discordant couple is poorly controlled. Seronegative partners in discordant a couple can be seropositive at any time with influence of predictors unless proper protective measures, counseling, and follow-up are given emphasis.
