-We studied the incidence and prognosis of acute neurologic complications in 281 children under 13 years of age with a diagnosis of acute bacterial meningitis. All the patients were examined daily by the same group of neurologists, using a standardized neurological examination. Patients with signs of encephalic lesions, unsatisfactory response to antibiotics or decreased level of consciousness were submitted to brain computer tomography. The overall lethality rate was 20.3% and cases whose causative agent was identified presented a higher lethality rate (23.7%) than those in which the agent was not found. The most important neurological abnormalities were meningeal signs (88.3%) followed by decreased consciousness (47.7%), irritability (35.2%), seizures (22.4%), fontanel bulging (20.6%) and cranial nerve palsy (14.2%). Seizures, cranial nerve palsy and the absence of meningeal signs were related to higher rates of lethality. Diminished consciousness, seizures, subdural effusion, abscess and hydrocephalus were the most important complications, respectively. We can conclude that acute bacterial meningitis continues to be an important health problem in developing countries and that public health measures will be necessary to minimize the impact of sequelae and reduce the mortality rate in children with that pathology.KEY WORDS: pyogenic meningitis, bacterial meningitis, septicemia, meningitis in children.Although the use of antibiotics has dramatically changed the mortality of patients with pyogenic meningitis, management of neurological complications remains as a significant problem 6,7 . Fatalities may occur in spite of appropriate treatment and may be related to cerebral edema, vasculitis,
RESUMO -Objetivo: descrever as características clínicas e laboratoriais da meningite piogênica em lactentes. Método: informações obtidas a partir do acompanhamento prospectivo dos lactentes com meningite piogênica, admitidos no Hospital Couto Maia no período de março a dezembro de 1997, foram inseridas em um banco de dados e analisadas com auxílio de programas estatísticos. Resultados: meningite piogênica foi mais prevalente em lactentes com idade entre 6 meses e 1 ano, sendo o agente etiológico mais freqüente o Haemophilus influenzae. A letalidade global foi de 25,9% e, entre os sobreviventes, 39,3% deixaram o hospital apresentando alguma anormalidade compatível com envolvimento encefálico ao exame neurológico. Conclusão: meningite piogênica em lactentes se constitui em enfermidade com taxa de letalidade elevada, sendo, na maioria dos casos, passível de prevenção. Consideramos de grande relevância a adoção de medidas profiláticas de saúde visando redução da incidência desta enfermidade.PALAVRAS-CHAVE: meningite piogênica, meningite bacteriana, lactentes, crianças. Clinical and laboratorial aspects of acute bacterial meningitis in infantsABSTRACT -Objective: to describe clinical and laboratorial characteristics of acute bacterial meningitis in infants. Method: data from the prospective follow-up of infants with acute bacterial meningitis, admitted at the Hospital Couto Maia between March and December 1997, were analyzed with specific statistical software. Results: acute bacterial meningitis was more prevalent in infants with ages varying from 6 months to 1 year. The most frequent etiologic agent was Haemophilus influenzae. The global lethality was 25.9% and among the survivors 39.3% left the hospital with some abnormality in the neurological exam compatible with the brain involvement. Conclusion: acute bacterial meningitis in infants is a high lethality disease that in the majority of cases can be prevented. We consider of great relevance the adoption of health prevention strategies in order to reduce the incidence of this disease.
