Group B Streptococcus late onset sepsis in very low birth weight newborns: 10 years experience

Purpose: The incidence of late-onset neonatal infection (LONS) group B streptococcus (GBS) in very low birth weight (VLBW) is still matter of debate. In the present 10-years retrospective study we investigated the epidemiology of GBS LONS in VLBW neonates. Materials and methods: From January 2006 to July 2015 we conducted a retrospective study in all preterm infants admitted at our third level referral center for neonatal intensive care (NICU). From our database we were able to retrieve all cases of bloodstream infections/meningitis GBS positive. Perinatal data were also collected Results: On a total of 13 747 infants 975 (7%) were VLBW and in seven cases of GBS LONS was observed with a incidence of 7.2/1000 live births. Conclusions: The higher rate of LONS GBS in our series offer additional support to further investigations in wider population in order to better define GBS screening and therapeutic management in a such specific population.
