RESUMEN
Reports on nervous system involvement in brucellosis are rare in children. We report nine children with neurobrucellosis. The clinical presentation included meningitis in six patients, one with encephalitis, one with meningoencephalitis and one with meningomyeloencephalitis. The blood from all patients showed elevation in Brucella microagglutination test titers (greater than or equal to 1:640) and in Brucella-specific enzyme-linked immunosorbent assay for IgM (greater than or equal to 1:800), IgG (greater than or equal to 1:800) and IgA (greater than or equal to 1:800) antibodies. Brucella melitensis was recovered from the blood in five patients and from the cerebrospinal fluid in three patients. The cerebrospinal fluid showed lymphocytic pleocytosis in eight patients with elevated protein in three, decreased glucose in four and a Brucella microagglutination test titer of greater than or equal to 1:80 in all. Treatment with a combination of oral tetracyclines with intramuscular streptomycin was successful in five patients, rifampin with streptomycin in two, tetracycline with rifampin in one and tetracycline, rifampin and streptomycin in one. No relapses, mortality or sequelae occurred in our patients.
