Prevalence and correlates of plasma cytomegalovirus viremia among newly reported HIV/AIDS patients in Taizhou city, 2017-2018

Objective To study the prevalence and correlates of plasma cytomegalovirus(CMV)viremia among newly reported antiretroviral therapy(ART)-naive HIV/AIDS patients in Taizhou during 2017-2018.Methods CMV DNA was measured in plasma specimens of newly reported ART-naive HIV/AIDS patients by quantitative PCR.Both univariable and multivariable logistic regression analyses were carried out to evaluate CMV viremia correlations among the individuals.Results Of 612 HIV/AIDS patients,480(78.4%)were male,125(20.4%)were over 60 years old,177(28.9%)were infected via homosexual transmission,and 430(70.3%)via heterosexual transmission.The prevalence of CMV viremia among HIV/AIDS patients was 13.4%(82/612).Multivariable logistic regression analysis showed that the risk of CMV viremia in CD₄⁺lymphocyte cells counts(CD₄⁺)≤200 cells/μl group was higher than CD_(40 counts>500 cells/μl(OR=5.10,95%CI:1.74-14.96,P=0.003);The median CMV DNA level(log10)of 82 viremic patients was 1.57(P₂₅,P₇₅:1.04,2.13);Viremic patients with CD_(40 counts≤200 cells/μl had the highest CMV viral load(P<0.01).Conclusions Among ART-naive HIV/AIDS patients,the prevalence of CMV viremia was significantly associated with immunodeficiency status.Further research is needed to evaluate the association between CMV viremia and the course of HIV infection.
