INTRODUCTION: Ataxia, deemed usually a minor sequela, follows childhood bacterial meningitis (BM) in up to 18% of cases. Although mostly transient and benign, it can predict permanent hearing loss and vestibular dysfunction. We explored the clinical meaning of ataxia by following its course in a large number of BM patients and examining its relation with hearing loss.
METHODS: The presence, degree (no, mild, moderate and severe) and course (transient, prolonged and late) of ataxia in BM were registered prospectively by predefined criteria. These data were compared with several patient, disease, and outcome variables including hearing loss (none, moderate, severe and profound) on day 7 of treatment and at a follow-up visit 1 month after discharge.
RESULTS: Ataxia was present in 243 of 361 (67%) patients on day 7, being slight in 21%, moderate in 38% and severe in 41%. Its course was transient in 41%, prolonged in 24% and late in 5%, whereas 30% of the patients did not present ataxia at any time. Ataxia associated most significantly not only with several measures of BM severity and suboptimal outcome (P < 0.0001), but also specifically, albeit not consistently, with hearing loss (P = 0.001). The degree of ataxia correlated with the extent of hearing loss (rho, 0.37; P < 0.0001).
CONCLUSIONS: Ataxia is more frequent and lasts longer after BM than learned from previous studies. The presence and intensity of ataxia associate with hearing loss and its magnitude.
