Background: The burden of zinc deficiency on children includes an increased incidence of diarrhea, failure to thrive (FTT) and short stature. The aim of this study was to assess whether children with FTT and/or short stature have lower dietary zinc intake and plasma zinc concentrations compared to controls. Methods: A case-control study conducted at the American University of Beirut Medical Center included 161 subjects from 1 to 10 years of age. Results: Cases had a statistically significant lower energy intake (960.9 vs. 1,135.2 kcal for controls, p = 0.010), lower level of fat (30.3 vs. 36.5 g/day, p = 0.0043) and iron intake (7.4 vs. 9.1 mg/day, p = 0.034). There was no difference in zinc, copper, carbohydrate and protein intake between the 2 groups. The plasma zinc concentration did not differ between the cases and controls (97.4 vs. 98.2 μg/dl, p = 0.882). More cases had mild-to-moderate zinc deficiency when compared to controls with 10.3 vs. 3.6%, p = 0.095. Conclusion: Our study did not show statistically significant difference in dietary zinc intake and plasma zinc concentrations between children with FTT and/or short stature compared to healthy controls. A prospective study is planned to assess the effect of zinc supplementation on growth parameters in FTT children.

Introduction: The human immunodeficiency virus (HIV) infection progressively destroys the immune system and increases the susceptibility to opportunistic infections. The aim of this study was to assess the benefits and safety of zinc supplements at nutritional doses. Methods: A randomized, double-blind, placebo control trial was performed in 40 adult patients that received either zinc sulfate or placebo daily during 12 weeks. The CD4 lymphocytes count was evaluated at the beginning and at the end of the intervention. Furthermore, we evaluated different clinical and epidemiological variables. Results: After the intervention, an increase ≥ 20% in CD4 lymphocytes was compared between groups; better response was observed in patients who received zinc (90% vs. 25%, p = 0.00), RR = 3.6 (95% CI 1.66; 7.8, p = 0.000) and reduction of relative risk of 74% compared to placebo. Conclusion: This clinical trial shows that patients who receive zinc sulfate supplement could increase the CD4 lymphocyte counting.
