Zinc supplementation in the management of shigellosis in malnourished children in Bangladesh

Abstract

Objective:

To assess the impact of zinc supplementation on clinical recovery, weight gain and subsequent growth and morbidity in moderately malnourished children with shigellosis.

Design:

A randomized, double-blind, controlled trial.

Setting:

Dhaka hospital of ICDDR,B: Centre for Health and Population Research, Dhaka, Bangladesh.

Subjects:

Fifty-six moderately malnourished children, aged 12–59 months with culture-proven shigellosis.

Methods:

Subjects were randomly allocated to receive zinc (20 mg/day elemental) in multivitamin syrup (intervention) or multivitamin syrup without zinc (control) in two equally divided doses daily for 2 weeks. All children received pivmecillinam in a dose of 15 mg/kg every 6 h for 5 days. After supplementation, children were followed in their respective homes every 2 weeks for 6 months.

Results:

Children receiving zinc recovered from acute illness significantly faster than the control children (P<0.05). The medians time (days) to recovery and disappearances of blood and mucous were significantly 50% shorter in the zinc-supplemented group compared to the control group. The mean body weight of zinc supplemented children increased significantly from 8.8 kg on admission to 9.2 kg (P<0.01) at recovery, which was not observed in the control children (from 9.3 to 9.6 kg; P=0.12). During the 6-month follow-up period, zinc-supplemented children had significantly fewer mean episodes of diarrhoea compared to the control children (2.2 vs 3.3; P=0.03).

Conclusion:

Zinc supplementation significantly shortens the duration of acute shigellosis, promotes better weight gain during recovery and reduces diarrhoeal morbidity during the subsequent 6 months.
