Abstract

To determine the frequency of Human Papillomavirus (HPV) in the placenta, in the colostrum and in the umbilical cord blood of parturient women and their newborns assisted at the Clinic of Gynecology and Obstetrics of the University Hospital of Rio Grande (RS), Brazil. Biopsies were collected from 150 placentas on the maternal side, 150 on the fetal side, 138 samples of umbilical cord blood and 118 of the colostrum. The placenta biopsies were collected from the central and peripheral portions. DNA was extracted according to the manufacturer's protocol and to a reference found in the literature. HPV was detected by the nested polymerase chain reaction (PCR-Nested) using primers MY09/11 and GP5/GP6. Genotyping was performed by direct sequencing. The participants responded to a self-applied questionnaire with demographic and clinical data, in order to characterize the sample. HPV was detected in 4% (6/150) of cases on the mother's side of the placentas, in 3.3% (5/150) on the fetal side, in 2.2% (3/138) in umbilical cord blood and in 0.84% (1/118) in colostrum samples. The vertical transmission rate was 50%. HPV-6 was the low-risk genotype found (60%) and the high-risk genotypes were HPV-16 and HPV-18 (20% each). These results suggest that HPV can infect the placenta, the colostrum and the umbilical cord blood.
