The Efficacy of Zinc as Adjunct Therapy in the Treatment of Severe Pneumonia in Children
The Efficacy of Zinc as Adjunct Therapy in the Treatment of Severe Pneumonia in Children Admitted to Mulago Hospital, Uganda.
Pneumonia is a leading cause of morbidity and mortality in children in developing countries. Zinc deficiency leads to impairment in tissue repair and immunodeficiency in children.At least two randomised controlled trials have shown that zinc supplementation improves the outcome of severe pneumonia in children (reducing duration of hospital stay and complications related to pneumonia).
However, there are conflicting results from other randomised controlled trials about its efficacy in children with pneumonia.The purpose of the current study is to determine the efficacy of zinc as adjunct therapy for in severe pneumonia in children aged 6-59 months. We hypothesize that the proportion of children who recover from severe pneumonia following zinc adjunct therapy [(10 mg once daily for seven days) for children aged <12 months and 20 mg daily for children aged ≥12 months]will be higher than the proportion of children who recover from placebo therapy.

Detaljeret beskrivelse
Zinc deficiency is a global nutritional problem affecting people with a low socioeconomic status in developing and developed countries. There is a high prevalence of zinc deficiency in Uganda as documented by Bitarakwate et al.Two clinical studies have shown that zinc supplementation improves the outcome of severe pneumonia in children by reducing duration of hospital stay and complications related to pneumonia. However, there are conflicting results from some previous studies about its usefulness in patients with pneumonia.
The objective of this study is to determine the effect of zinc supplement as adjunct therapy in the treatment of severe pneumonia in children less than five years admitted to Mulago hospital, Kampala, Uganda.
This will be a randomized, double-blinded, placebo-controlled trial of zinc adjucnt therapy. Three hundred and twenty eight children with severe pneumonia will be randomised to receive either zinc (a daily dose of 20 mg for children more than one of age and 10mg for those less than one year or placebo once daily for seven days.
The primary outcome will be Time taken to :normalisation of respiratory rate, temperature and oxygen saturation.
Secondary outcome:Proportion of study children who will die during the follow up period,Proportion of children who develop drug adverse effects data will be analysed using Kaplan Meir survival curves.
