[Evaluation of the therapeutic efficacy of dexamethasone in meningococcal meningitis]
OBJECTIVE: To evaluate the efficacy of dexamethasone as an auxiliary therapeutic tool to the antibiotics in hospitalized children with meningococcal meningitis. METHODS: A retrospective clinical comparative study was undertaken with children from a pediatric ward affected by laboratory proved meningococcal meningitis at a university hospital. Cases of children in state of shock at admission or deceased in the first 24 hours were excluded. During the period from 1987 to 1989 33 children were treated only with antibiotics (group A), while from 1990 to 1993 other 66 children received additionally dexamethasone (12mg/m2/24h) by intravenous route during four days beginning at the admission to the hospital (group B). The two groups were evaluated at baseline through prognostic scores and analysis of their clinical and laboratorial characteristics obtained from data recorded at the admission. The parameters to evaluate dexamethasone efficacy were the comparative number of neurologic and systemic complications detected at the hospital, and the liquoric profile (leukocyte count, glucose and protein content) verified between day 9 and day 11 of hospitalization. RESULTS: The profile of the two groups (A and B) were homogeneously evaluated by the illness severity scores and their clinical and laboratorial characteristics. Nine complications were recognized in group A (27.2%) and 21 (31.8%) among those of group B, difference not significant. Likewise, there were not observed liquoric differences between the two groups related to the chimiocytologic pattern. CONCLUSIONS: No effect of dexamethasone therapy to prevent neurologic and systemic meningococcal meningitis complications was observed during hospitalization. Similarly no favorable effect in relation to the liquoric pattern verified between day 9 and day 11 of hospitalization was recognized.
