DIAZ ALVAREZ, Manuel; CLAVER ISAS, Daniel e PEREZ AMARILLO, Julián. Infections due to Streptococcus agalactiae at an open neonatology service. Rev Cubana Pediatr [online]. 2008, vol.80, n.4, pp. 0-0. ISSN 1561-3119.
INTRODUCCIÓN. The objective of the present study was to know the clinical and epidemiological characteristics of the infections caused by group B Streptococcus in newborns discharged from maternal hospitals. METHODS. A descriptive study that included consecutive infants with infections due to Streptococcus agalactiae admitted in the Neonatology Service of «Juan M. Márquez» University Pediatric Hospital from February 1992 to December 2007 was conducted. Different clinical and epidemiological variables were processed and analyzed, with calculation of incidence and lethality rates and relation among the categoric variables. RESULTS. There were 76 newborns with infection due to Streptococcus agalactiae for an average annual rate of 1.9 x 100 admissions. It was observed a predominance of late onset infections and of those acquired in the community (89.5 % y 93.4 %, respectively). Meningitis was the most common clinical form followed by isolated bacteriemia. 56 of the 76 newborn infants had bacteriemia (73.7 %). Streptococcus agalactiae showed a high sensitivity to penicillin, erythromycine, vancomycin, cefotaxime and cloranphenicol. There were 7 deaths (9.2 %). All of them had infection of the CNS. CONCLUSIONS. Streptococcus agalactiae is an agent that causes infections affecting the newborn infant, both in the community and in the hospital. These infections may be lethal in some patients with infection of the CNS with o without bacteriemia, even when they maintain a pattern of elevated susceptibility to betalactamic antibiotics.
