Genotipificación del virus del papiloma humano en mujeres embarazadas VPH positivas

Abstract

Background: Pregnant women infected with human papillomavirus have medical conditions that influence the course of the disease and can increase the possibility of vertical transmission. Objective: To identify the most common human papilloma-virus genotypes in pregnant women. Method: Retrospective, observational and descriptive study. Cervical scraping samples were used. The extraction of genetic material was done by the phenol-chloroform technique and was amplified using universal primers MY09/MY11. Positive samples were genotyped with a kit that detects 37 different genotypes. Results: Three hundred forty-one genotypes were identified. The most frequent were 16 (10.3%), 52 (8.8%), and 59 (8.6%). In 75.9% the detection was with one genotype and in 42.7% multiple infections were detected. Conclusions: It is known that human papillomavirus infection in pregnant women will rarely evolve to invasive lesions. Both possible short-and long-term obstetric complications, as well as possible repercussions on the health of the newborn, should be considered. The high detection of genotype 16 suggests close follow-up to consider an optimal post-pregnancy approach.
