Hemophilus influenzae type b meningitis: pediatric overview.

Abstract

The authors valued the incidence and clinical therapeutic aspects of Haemophilus influenzae type b (Hib) meningitis in children. They report a retrospective study, in children, with diagnosis of acute purulent meningitis, from January 1982 to December 1994, aged between 1 month and 14 years. Particular attention was direct to Haemophilus influenzae type b meningitis (20 cases). The incidence rate of Hib meningitis in the overall cases (89) was 22.47% (20), while among children younger than 5 years Hib was the most frequently pathogen isolated (20/58-34.47%). In 1/4 of cases, particularly in children younger than 1 years, exordium was aspecific and unclear. At admission culture and examination of Cerebrospinal Fluid (CFS) have been done. CFS was cultured on blood agar and chocolate plates. A latex agglutination test was used for rapid detection of the bacterial antigens. In some cases we looked for bacterial antigens in urine. 20% of children had complications and 10% had sequelae (1 years of follow-up). We didn't have any dead. Antibiotic treatment was principally with Ampicillin, Cephalosporin and Chloramphenicol. The results of this study confirm the Hib gravity and suggest that the administration of conjugate vaccine against Hib to all living in Italy is justified.
