Background: Data are lack on predicting features of meningitis in diarrheal children although the great clinical importance. Objective: To evaluate clinical and laboratory features in predicting meningitis in under-fifteen children having diarrheal illnesses. Methods: Children aged 1 month to 15 years, admitted in the ICU of the Dhaka Hospital of icddr, b between March 2011 and February 2012 with fever and seizure or altered consciousness and having LP done were enrolled into this analysis. Those children who had abnormal CSF findings [pleocytosis (normal range of leukocyte, 0-10/mm 3) and/or elevated protein (normal range, 0.10-0.45 mg/dl) and low glucose (normal value, 60% of corresponding blood glucose)] were defined as meningitis. Comparison was made between children with (cases = 17) and without meningitis (controls = 66) from our study children. Data were retrospectively collected from SHEBA, an online database system of the Dhaka Hospital of icddr, b. Results: Death was significantly higher among the cases compared to the controls (29% vs. 3%, p = 0.003). In logistic regression analysis, after adjusting for potential confounders, cases frequently had hypoxemia (95% CI 1.55-21.93), absent peripheral pulse (95% CI 1.95-27.13) and neutrophilia (95% CI 1.13-17.00). Conclusion: Our data suggest that children with meningitis had higher case fatality rate. Simple independent predictors of meningitis such as hypoxemia, absent peripheral pulse, and neutrophilia may help clinicians to initiate early and prompt management in order to curve lifelong sequel due to meningitis and death in such patient population especially those in resource poor settings.
