Patterns of single and multiple HPV infections in female: A systematic review and meta-analysis.

BACKGROUND

Data on the patterns of single and multiple HPV infections are largely limited to small size studies, and the regional difference have not been systematically examined.

METHODS

A literature search was conducted using PubMed, Embase, and Web of Science databases up to Sept 22, 2023. The pooled prevalence of HPV infection were calculated using random-effects meta-analysis. Subgroup analysis was used to explore the heterogeneity, and publication bias was evaluated by Egger's test and Begg's test.

RESULTS

There were 121 studies included with 1,682,422 participants. Globally, the most common genotypes of single HPV infection were HPV16 (7.05 %), 18 (1.94 %), 52 (1.93 %), 58 (1.68 %), and 31 (1.53 %), as well as HPV 16 (4.91 %), 31 (2.68 %), 52 (2.20 %), 51 (1.99 %), and 18 (1.96 %) in multiple HPV infections. Apart from HPV16 and 18, HPV52 and 58 were common in Asia, HPV31 and 51 was in Europe, North and South America, and HPV35 and 45 were in Africa. The prevalence of HPV infection among different age groups (<30, 30-50, >50 years age groups) was 20.93 %, 16.27 %, and 18.69 %, respectively. The single HPV infection prevalence in the No-ILs, LSILs, HSILs, and cervical cancer groups were 16.17 %, 51.60 %, 57.12 %, and 62.88 %, respectively, as well as in multiple infections were 5.09 %, 30.93 %, 32.86 %, and 21.26.

CONCLUSION

Developing local HPV vaccines is necessary based on the HPV infection pattern. It is essential to educate young women to get vaccinated and encourage elderly women to have regular cervical cancer screenings to reduce the danger of cervical cancer.
