[Early neonatal infection caused by Streptococcus pneumonias: report of 3 cases]. / Infection neonatale precoce a streptococcus pneumoniae: a propos de 3 observations.

BACKGROUND: S pneumoniae is a rare cause (1-8 %) of maternofetal infection causing an important morbi-mortality in the newborn and the mother. AIM: To report 3 cases of early neonatal infection due to S pneumonia. CASES REPORT: Three cases of early neonatal infection due to S pneumoniae are reported. The three newborns were at term or near term babies with a vaginal delivery in two cases and a caesarean section in one case. They presented severe symptoms, with a progressive onset after birth, leading to hypoxemic pneumonia in one case and to septic shock in two newborns associated with meningitis in one case. S pneumoniae was isolated in the blood culture in two patients with positive soluble antigens in the cerebrospinal fluid in one case and positive peripheral bacteriological swabs in the other case. In the third case, S pneumoniae was isolated in the tracheal sample of the newborn and his mother. S pneumoniae was sensitive to ampicillin in two patients and of decreased sensitivity to ampicillin in one patient. The clinical course was favourable in the three patients after hospitalization in the intensive care unit. CONCLUSION: Early neonatal infections caused by S pneumonia are rare and are an important cause of morbi-mortality in the newborn and the mother.
