Screening of Hemolytical Streptococcus of Group B inPregnancy and Prevention of Infection in Newborns

Overview

Objective:
The aim of this study was to evaluate the infl uence of Group B streptococcus (GBS) screeningand intrapartum antibiotic prophylaxis to the incidence of GBS disease in newborns.Design: Prospective non-randomised study.Setting: IInd Clinic of Obstetric and Gynaecology LFUK and FNsP Ružinov, Bratislava, Slovakia.Methods: We enrolled 3023 newborns (754 in the study group, 2269 in the control group), whichwere born between 1.9.2000 and 31.3.2003. In both groups we compared following variables: totalnumber of infectious diseases in newborns, number and forms of GBS neonatal disease, numberof perinatal death due to GBS disease.Results: There was no GBS disease in the study group of 754 newborns. Mothers of these newbornshad one screening culture in 35-36th week of gestation. One swab was taken from vagina andanus. GBS carriers (161-21.4%) were administered i.v. intrapartum antibiotic prophylaxis withPenicillin G i.v., or, when allergy to penicillin was in history, with Clindamycin i.v.In the control group of 2269 newborns, whose mothers had no prevention, the incidence of GBSneonatal disease reached 7.5/1000 newborns (17 cases). The incidence of invasive GBS neonataldisease was 2.6/1000 newborns.Conclusion: The authors have noticed a signifi cant decrease in incidence of GBS neonatal diseaseafter implication of GBS screening and intrapartum antibiotic prophylaxis.
