The study was conducted in three hospitals in New Delhi, India.

Bacterial infections common in small children
Of the one million neonatal deaths that occur every year in India, more than a quarter are attributed to serious bacterial infections. Despite advances in antimicrobial treatment, outcomes remain poor. The development of inexpensive and accessible initiatives that could improve treatment outcomes and reduce mortality is important.

Supplement to standard treatment
Reduced risk of treatment failure means shorter time in hospital, lower treatment cost, and possibly reduced number of deaths. The researchers in this study wanted to estimate the efficacy of 10 mg of oral zinc daily combined with standard antibiotic treatment in infants with probable serious bacterial infection. The infants were aged between 7 and 120 days.

Fewer treatment failures with zinc
352 infants were randomly assigned to receive zinc and 348 to placebo. Significantly fewer treatment failures occurred in the zinc group (10%) than in the placebo group (17%) – the relative risk reduction was 40%. Zinc treatment of 15 infants would accordingly prevent 1 treatment failure. Use of zinc also reduced the number of deaths, although the difference between the groups was not statistically significant.

The study concludes that zinc could become an accessible and inexpensive intervention to improve treatment outcomes of such infections and thereby reduce infant mortality.

The study was funded by the Government of India as well as by three grants through the CiH: EU-INCO-DC (“Community- and health facility-based intervention with zinc as adjuvant therapy for pneumonia to enhance child health and nutrition”),  The Research Council of Norway (“Focus on Nutrition and Child Health: Intervention Studies in Low-income Countries” as well as The Meltzer Foundation (“Zinc as treatment for severe pneumonia in young children”)
