Human papillomavirus prevalence and type distribution in Chinese juvenile-onset recurrent respiratory papillomatosis patients

Abstract

Objective: To evaluate HPV prevalence and type distribution in Chinese juvenile-onset recurrent respiratory papillomatosis (JoRRP) patients. Methods: We searched China National Knowledge Infrastructure, Wanfang data, China Biology Medicine disc, PubMed, Embase, and the Cochrane Library for studies assessing HPV infection of Chinese JoRRP patients up to 1 October, 2022. Two authors independently performed literature selection, data extraction, and quality assessment. HPV prevalence and HPV type-specific prevalence were pooled using a random effects model after Freeman-Tukey double arcsine transformation. All analyses were performed with R 4.1.3 software. Results: Nineteen publications investigating HPV infection of JoRRP patients were included in the final analyses. Of these, 16 studies reported HPV prevalence with a sample size of 1 528 patients, and 11 studies reported HPV6 prevalence and HPV11 prevalence with a sample size of 611 patients. All studies were graded as medium quality. In Chinese JoRRP patients, the synthesized HPV prevalence was 92.0% (95%CI:86.0%-96.6%, I2=87%), HPV6 prevalence was 42.4% (95%CI:34.9%-50.1%, I2=61%), and HPV11 prevalence was 72.3% (95%CI:59.0%-83.9%, I2=87%). All the pooled prevalence persisted in subgroup analyses stratified by publication year, sample size, and specimen type (P>0.05). There was no evidence of publication bias. In Chinese JoRRP patients, HPV16, 18, 31, 33, 52, and 58 prevalence was very low. Conclusions: Our findings suggested high HPV prevalence in Chinese JoRRP patients, and the most common HPV types were HPV6 and HPV11.
