RESUMO
Objective:To analyze the incidence of human papillomavirus (HPV) infection in 1 902 patients and to evaluate the efficacy of drug treatment in 266 patients, aiming to provide reference for the treatment of HPV infection.Methods:The subtypes of HPV isolated from 1 902 patients aged 15-86 years visiting the venereology outpatient clinic of Tianjin Medical University General Hospital from October 2019 to May 2021 were identified by polymerase chain reaction-reverse dot blot hybridization. Drug treatment efficacy in 266 patients of them was retrospectively analyzed.Results:The overall incidence of HPV infection in the 1 902 patients was as high as 53.84% (1 024/1 902). It was 52.60% (689/1 310) in males and 56.59% (335/592) in females. There was no significant difference in the incidence between males and females ( P>0.05). The most common HPV genotype in males and females was HPV6 [15.27% (200/1 310) and 21.96% (130/592)], followed by HPV16 [10.61% (139/1 310) and 9.46% (56/592)], HPV11 [9.31% (122/1 310) and 8.61% (51/592)], HPV52 [6.79% (89/1 310) and 8.95% (53/592)] and HPV43 [5.64% (87/1 310) and 8.45% (50/592)]. The majority of HPV-positive patients were aged between 20 and 39 years. There were 476 cases (25.03%, 476/1 902) of single-type infection and 548 cases (28.81%, 548/1 902) of multiple infection. The incidence of multiple infection was higher than that of single-type infection ( P<0.05). The incidence of multiple infection in females was higher than that in males ( P<0.05). Among the 266 patients, 106 were treated with Paiteling, a traditional Chinese medicine (TCM) preparation, and 68 of them tested negative (64.15%) after treatment. Fifty-eight patients were treated with recombinant human interferon α2b and 22 of them (37.93%) tested negative after treatment. Twenty out of the 56 subjects treated with imiquimod tested negative after treatment. Eight out of the 46 patients without treatment also turned negative. Conclusions:The incidence of HPV infection in the 1 902 patients visiting the venereology outpatient clinic was very high, and most of them were young adults. Multiple infection was more common than single-type infection. Topical application of drugs such as Paiteling, recombinant human interferon α2b and imiquimod was effective in treating HPV infection.
