Background

Human herpesvirus type 8 (HHV-8) can be transmitted through unprotected sex as HIV. We aimed to investigate the seroincidence of HHV-8 and associated factors among people living with HIV (PLWH).

Methods

From 2014 to 2018, blood samples of PLWH on the first date of HIV care were determined for antibodies against HHV-8. Individuals testing HHV-8-seronegative at baseline were followed for at least four months to estimate the annual seroconversion rate. To identify the factors associated with HHV-8 seroconversion, we compared the clinical characteristics between seroconverters and non-seroconverters who were matched for observation duration.

Results

The HHV-8 seroprevalence increased from 8.1% in 2014 to 20.0% in 2018. HHV-8 seroconversion occurred in 154 (14.7%) PLWH after a total of 2652.16 person-years of follow-up (PYFU), resulting in an overall incidence rate of 5.62 per 100 PYFU, which increased from 3.20 to 6.84 per 100 PYFU during the study period. HHV-8 seroconverters were less likely to have chronic hepatitis B virus (HBV) infection (1.9% vs 10.6%) and more likely to be antiretroviral-naïve on entry into care (87.7% vs 75.4%) (both p < 0.05). In multivariate logistic analysis, men who have sex with men (MSM) (adjusted odds ratio [aOR], 2.22; 95% CI, 1.01–4.86), being antiretroviral-naïve (aOR, 2.91; 95% CI, 1.27–6.67), and chronic HBV infection (aOR, 0.13; 95% CI, 0.03–0.61) at baseline were associated with HHV-8 seroconversion.

Conclusions

An increasing trend of HHV-8 infection was observed among PLWH in Taiwan between 2014 and 2018. MSM and being antiretroviral-naïve were associated with higher risk for HHV-8 seroconversion.
