Sequelae from meningococcal meningitis in children: a critical analysis of dexamethasone therapy

Abstract

-Objective:To evaluate the effectiveness of dexamethasone as an adjunctive therapy to antibiotics in children with meningococcal meningitis. Method: A total of 81 children diagnosed with meningococcal meningitis hospitalized in sequence were studied at the University Hospital of São Paulo University, with the objective of evaluating the presence of sequelae in four different groups of patients, following the administration of dexamethasone: Group I -25 patients who received the first dose at least 10 minutes before the introduction of the antibiotic therapy; Group II -19 patients who received the corticosteroid concomitantly; Group III -14 patients for which the dexamethasone was administered after beginning the antibiotic scheme; Group IV -23 patients that did not receive dexamethasone. The groups were evaluated for homogeneity through the prognostic indexes and clinical and laboratory characteristics, based on the records obtained at hospitalization. Results: Some degree of sequelae occurred in 16 (26.22%) of the survivors and 23 patients (28.39%) coursed with sequelae or died. The mean period of neurological attendance was 36.97 months and neurological alterations were detected in 16.17% of the patients. No significant difference was found between the four groups. There was also no statistical difference in the comparison of the neurological sequelae in the children from group IV with the children of groups I and II or even with groups I, II and III analyzed as a whole. The presence of hearing loss occurred in 11.11% of the patients, again there was no significant difference between the four groups. Psychological evaluation was performed using the WPSSI and WISC tests. A mild mental disability was detected in one patient from group I and another in group III. The overall analysis of the sequelae (neurological, auditory and intellectual level) also did not demonstrate any significant difference between the four groups. Comparing the children from groups I and II together and also groups I, II and III as a whole with the children in group IV also failed to detect a significant difference arising from the use or nonuse of the corticosteroid. Conclusion: Dexamethasone was not proven to be effective in decreasing the number of sequelae among patients with meningococcal meningitis.KEY WORDS: sequelae, meningococcal meningitis, dexamethasone.

West Nile Virus infection with hearing loss

“…Hearing loss is an uncommon but recognized sequela of meningitis. 11,12 Ototoxicity from medications such as vancomycin is possible but the toxicity is dose-dependent and the exposure of our patient to vancomycin was after her hearing loss began and also brief with the administration of only three 1 g doses, each 12 h apart (a serum level was not drawn). 13e15 We postulate that the development of neuroinvasive disease in our patient was enhanced by the exogenous immunosuppression used to treat her myasthenia gravis.…”

Clinical and laboratory aspects of adults and children admitted with meningococcal meningitis to a tertiary hospital in Fortaleza, Ceara, Brazil

“…This pratice is associated with the decrease the incidence of complications after the disease, [30] but the literature does not confirm decrease the frequency neurological sequelae, such as hearing loss, in meningococcal meningitis. [31] In relation to antibiotic therapy, the current conduct relates to the use of antibiotics with good penetration in cerebrospinal fluid, such as ceftriaxone. In French series with 1344 patients with meningococcal meningitis (73% with positive culture), all strains were susceptible to cefotaxime and ceftriaxone, while 41.6% showed reduced susceptibility to penicillin, and 25.7% for amoxicillin.…”
