We conducted a retrospective study of cytomegalovirus viremia in Thai human immunodeficiency virus patients starting combination antiretroviraltherapy with CD4 counts <200 cells/mm3. Cytomegalovirus (CMV) viremia was present in 26.3% of patients, and CMV DNA >500 copies/mL was associated with increased mortality.Background Prevalence and risk factors of cytomegalovirus (CMV) viremia in patients infected with human immunodeficiency virus (HIV) starting antiretroviral therapy (ART) in developing countries are understudied.Methods We measured CMV DNA in stored plasma specimens of 293 Thai HIV patients starting ART at CD4 counts <200 cells/mm3. We examined Cox proportional hazard ratios (HRs) of 24 months mortality and new AIDS-defining illness (ADI).Results Of 293 patients, 159 (54.3%) were male. The median age was 33 years. The median baseline CD4 count was 82 cells/mm3, and the median HIV-1 RNA was 4.9 log10 copies/mL. In total, 273 (93.2%) patients started potent combination ART, and 20 (6.8%) started dual nucleoside reverse transcriptase inhibitor (NRTI) therapy. CMV DNA was detected in 77 of 293 patients (26.3%) at baseline, and 9 of 199 patients with available specimen (4.5%) after 6 months of ART. The median CMV DNA was 548 copies/mL (interquartile range [IQR], 129–3849) at baseline and 114 copies/mL (IQR, 75–1099) at 6 months. In univariate analysis, death was associated with baseline CDC stage C, hemoglobin <10 g/dL, lower CD4 count, and CMV viremia. In multivariate analysis, only CMV DNA >500 copies/mL was significantly associated with mortality (HR: 7.28; 95% CI, 1.32–40.29, P = .023). CD4 count was the only variable associated with new ADI (HR: 0.70 per 50 CD4 cells increase; 95% CI, .49–.997, P = .048).Conclusions In these Thai patients with advanced HIV disease, CMV viremia was frequent, and CMV DNA >500 copies/mL predicted increased mortality despite ART initiation. This calls for increased attention to screening of active CMV infection in advanced HIV patients in developing countries. Trials assessing preemptive anti-CMV therapy may be warranted.
