title: [Long-term follow-up of bacterial meningitis - sequels in children and adults: incidence, type, and assessment issues].
abstract: Bacterial meningitis remains a major cause of death and neurological and hearing sequels. In adults, the death rate ranges from 16 to 37% in meningitis due to Pneumococcus pneumoniae and neurological sequels occur in 30 to 52% of survivors. In childhood, the prognosis is better, with a death rate ranging from 2 to 15%, higher for Pneumococcus pneumoniae. Seventy-five percent of children survive without any sequel, 15% with hearing disorders (up to 30% with Pneumococcus), and rarely (3-4%) present with mental retardation, motor deficit, or epilepsy. In addition to the type of germ, the risk of sequels is six times higher in case of Pneumococcus, several factors of poor prognosis are described on admission: degree of coma, neurological deficit, cranial nerve palsy, high protein level, high erythrocytes count and low leukocytes count in CSF (less than 600 or 1000 leukocytes per microliter). Any neurological complication such as epilepsy, stroke, brain edema, hydrocephalus, or hemodynamic failure will be correlated to a poor outcome. Hearing must be tested within 15 days, followed by audiologic consultation and MRI focused on labyrinths to detect early onset cochlear ossification. One year after meningitis, behavior and cognitive skills must be assessed, including IQ, memory, attention and executive functions, adaptive abilities, to set up specific educative and teaching strategies.
