Antibiotic Therapy for Children with Diarrhea in a Low-Resource Setting: A Syndromic Approach.

Objective: To compare age and protein-energy malnutrition (PEM) - the predispositions - and fever and abnormal leukocyte count (ALC) - the SIRS criteria - in hospitalized children with and without diarrhea.

Design: A prospective case-control study.

Setting: A pediatric ward of a general hospital in a low-resource setting.

Participants: Totally, 445 consecutive admissions to the pediatric ward of a general hospital over a period of 1 year were included in this prospective case-control study; hemodynamically unstable subjects (11) were excluded.

Interventions: Age, PEM, fever, and ALC were assessed in 59 patients with diarrhea and compared with 375 control patients without diarrhea. Odds ratios with confidence intervals were determined; the chi-square test and binary logistic regression analysis were also performed.

Main Outcome Measures: Associations of diarrhea with age, PEM, fever and ALC singly and various combinations of predispositions and SIRS parameters.

Results: Infancy and ALC were significantly associated with diarrhea. PEM or fever alone was not significantly associated with diarrhea; however, the probability of developing diarrhea was significantly higher when a combination of ALC and PEM was observed. The combination of infancy, PEM, and ALC carried a sensitivity of 81·36%; for other combinations, sensitivity varied between 70% and 80%. The combination of infancy and ALC had the lowest sensitivity (59·32%) but the best specificity (61·07%).

Conclusion: The association/presence of a combination of SIRS parameters (fever and ALC) and predispositions (infancy and PEM) in children with diarrhea may help in deciding whether antibiotic therapy should be initiated.
