Abstract
BACKGROUND: Although, there is a variable burden of human papillomavirus (HPV) in women infected with HIV in developing countries, there are few studies that attempted to surmise such variable evidences. This review aimed to estimate the pooled prevalence of HPV genotype distribution and risk factors contributing to HPV infection among women infected with HIV in low- and middle-income countries. METHODS: We conducted a systematic review and meta-analysis of studies conducted in developing countries and reported HPV prevalence. We searched electronic databases: PubMed/Medline, SCOPUS, ScienceDirect, Excerpta Medical Database from Elsevier, Web of science, Cumulative Index of Nursing and allied Health Sciences and Google scholar databases to retrieve primary studies published in English language till 11th August 2019. We used random-effects model to estimate the pooled prevalence of HPV genotypes, and funnel plot to assess publication bias. The registration number of this review study protocol is CRD42019123549. RESULTS: We included nineteen studies with a total of 8,175 participants in this review. The prevalence of HPV was extremely heterogeneous across the studies (χ(2)(=) 3782.80, p value < 0.001, I(2) = 99.6%). The estimated pooled prevalence of all HPV genotypes was 63.0% (95% CI: 48.0-78.0) while the pooled prevalence of high risk and low risk HPV genotypes were 51.0% (95% CI: 38.0-63.0) and 28.0% (95% CI: 12.0-43.0), respectively. The pooled prevalence of HPV genotype 16 was 20%, while genotype 18 and 52 were 15% and 13%, respectively. Different risk factors reported for HPV infection and the frequently reported were low CD4 count below 200 cells/mm(3) and high HIV viral load. CONCLUSION: The pooled prevalence of HPV among HIV infected women in low- and middle-income countries was considerable and the proportion of high risk HPV genotypes were high when compared with low risk genotypes. Therefore, it is essential for the HPV prevention program to prevent the double burden of HPV and HIV in women.
