HAEMOPHILUSINFLUENZAE TYPE B MENINGITIS REVEALING HYPOGAMMAGLOBULINEMIA IN A VACCINATED CHILD

Haemophilusinfluenzae type b (Hib) meningitis is a major therapeutic emergency, and its incidence has been significantly reduced by vaccination.We report the case of a 4-year-old girl vaccinated against Hib, hospitalized for Haemophilus influenza type b meningitis revealed by a febrile meningeal syndrome and having revealed a hypogammaglobulinemia. The child was treated with antibiotic therapy associated with corticosteroid therapy and immunoglobulin substitution with a good evolution. Through this observation we conclude that the assessment of the immune deficiency must be systematically proposed in front of a neuromeningeal infection with Hib.
