Abstract
AIMS: To estimate the impact of human papillomavirus (HPV) infection on spontaneous abortion, spontaneous preterm birth (sPTB), pregnancy rate of females undergoing assisted reproductive technologies (ART), and spontaneous abortion of ART pregnancy. METHODS: PubMed, Medline, Embase, and the Cochrane Library were searched until December 16, 2016. The OR or relative risk (RR) with its corresponding 95% CI were selected as effect size. Subgroup analysis of HPV genotype infection (high-risk HPV [HR-HPV] or indiscriminate genotype) was performed. Statistical analysis was conducted using STATA 12.0. RESULTS: Eighteen studies were included. Eight studies revealed no significant association between HPV infection and spontaneous abortion (OR 1.40, 95% CI 0.56-3.50). However, subgroup analysis showed indiscriminate genotype HPV infection increased the ratio of spontaneous abortion with OR of 2.24 (95% CI 1.37-3.65), while HR-HPV infection had no significant effect (OR 0.65, 95% CI 0.21-1.98). The results indicated that HR-HPV infection was a risk for sPTB with a pooled OR of 2.84 (95% CI 1.95-4.14). HPV infection was found to be independent of the ART-based clinical pregnancy rate (RR 1.04, 95% CI 0.64-1.70) and spontaneous abortion of ART pregnancy (RR 1.47, 95% CI 0.86-2.50). CONCLUSIONS: Indiscriminate HPV genotype infection can increase the risk of spontaneous abortion and HR-HPV infection was a risk factor for sPTB. However, there was not enough evidence to indicate the association between HPV infection and pregnancy rate of ART, and spontaneous abortion of ART pregnancy. Different genotypes of HPV infection may play a discrepant role in adverse pregnancy outcomes.
