[Plasma cytomegalovirus viremia prevalence among HIV-infected individuals: a Meta-analysis].

Objective

To understand the prevalence and correlates of plasma cytomegalovirus (CMV) viremia among HIV-infected individuals by Meta-analysis.

Methods

A systematic literature retrieval was conducted by PubMed, CNKI, Wanfang, and VIP databases for the information about the prevalence of plasma CMV viremia among HIV-infected individuals published from 2011 to 2020. Meta-analysis was used to calculate the pooled prevalence after literature screening and data extraction.

Results

Fifteen studies were included, and the total sample size was 5 076. The random effect model showed that the pooled prevalence of CMV viremia among HIV-infected individuals was 26.2% (95%CI: 16.8%-35.6%, I2=99%); Subgroup analysis and Meta-regression showed that the sources of heterogeneity among different studies were: the proportion of individuals aged >30 years in sample, the proportion of homosexual transmission in the sample, the proportion of individuals whose HIV viral load > 104 copies/ml, the proportion of individuals whose CD4+T lymphocyte counts <200 cells/μl.

Conclusion

Among HIV-infected individuals, the prevalence of CMV viremia was high and might be associated with age, HIV transmission mode, the status of HIV/AIDS.
