ResumenRecien;emente se ha puesto en duda la utiiidao de la dexametasona en el mane'o de la mening : tis bacteriana aguda en n'nos, planlecndo un se' : o problema de decision clinica. Yo que el uso de cexametasona no solo tiene bases empiricas, se reviscrcn los respaldos biologicos de su empleo, asi cono ensayos clinicos contralados en nines. Cinco es'udios cumplieron los criterios de inclusion. Los resullados respaldan el empieo de dexcmetasonc en la p'evencion de secuelas nejrologicas (RR = 2,37; 1C: 95% = 1,34 a 4,22; p < 0,004) y auaiolagicas (RR = 2,25; 1C 95% = 1,59 a 3,2; p < 0,00003]. Las diferencias entre los resuhados de los estud'os pueden exolicarse por la faltc de comparabilidad (desigualdaaes en la duracion de la en!~ermedad antes del ciagnostico, tratamientos y etiologia). Aunque los efectos de la dexanetasona no son de la mognitud esoerada de los fundomentos biologicos, el esteroiae disminuye ;os impacts globales neurologicos y audiologiccs en los sobrevivientes y deberia considerarse como terao'a adjunta en Tieningitis bacteriana aguda, para emplearla con la de'oida cautela a las interrogates sobre covariables tales ccmo la etiologia.

Dexamethasone in acute bacterial meningitis in children: a meta-analysis Recent pjb: icaticns cast doub's about the usefulness o" dexomethasone in the management of acute bacterial merinaris in children, w n ich ra'ses serious problems concerning Clinical decisions. Since the use of dexamethasone is not only based on enoirical data, we reviewed the biomedica' infomation which suppo'ts it, as well as clinical studies in chiloren. Five studies met inclussion cMeria. Results favor dexarrethcsone treatment to prevent neurological (RR=2.37; 1C: 95%= 1.34 to 4.22-0 < 0.004) and auciolagical sequelae (RR = 2.25; 1C: 95% -1,59 to 3.2; p < 0.00003). Differences found among study resuits may be explained by iiethodologica' reassons like unequal periods of illness before diagnosis, trearrrents and etiology-Although ^hese effect ere not as great as expected given the oiological ra-ionae fo' its use, dexamethcsone does reduce overall neurological and audiciogical impact in children surviving from acute bacteria 1 meningitis and should be judiciously consice.-ea as an adjunt therapy, given uncertainties about some ccvanctes such as etiology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
