BACKGROUND The role of micronutrient status for the incidence and clinical course of cutaneous leishmaniasis is not much studied. Still zinc supplementation in leishmaniasis has shown some effect on the clinical recovery, but the evidence in humans is limited. OBJECTIVE To compare biochemical nutritional status in cutaneous leishmaniasis patients with that in controls and to study the effects...

BACKGROUND Iron supplementation can decrease the absorption of zinc and influence other antioxidants levels such as vitamin C. This study aimed to investigate the effect of iron supplements alone and in combination with vitamin C on zinc and vitamin C status in iron deficient female students. METHODS In a double-blind randomized clinical trail, 60 iron deficient students were selected from 28...

This review summarizes the results of published, randomized clinical trials that have examined the impact of administration of micronutrients, singly or in combination to infants, preschool and school children on linear growth. Supplementation of single micronutrients resulted in small or no benefits on linear growth. A meta-analysis of zinc supplementation trials confirmed that zinc has a sign...

Zinc supplementation in children in endemic area of zinc deficiency had been reported of growth enhancement; however, the results were inconsistence. This study aimed to evaluate the efficacy of zinc supplementation on growth of school-aged children. A randomized double-blinded controlled trial was conducted in 140 Thai school children. Placebo or zinc bisglycinate (15 mg element zinc) were tak...

Background Studies have shown that zinc and selenium deficiency is common in nonalcoholic fatty liver disease (NAFLD). However, the effects of zinc and selenium co-supplementation before and/or after disease progression on NAFLD are not clear enough. The aim of this study was to compare the effects of zinc and selenium co-supplementation before and/or after disease progression on NAFLD prognosi...

Zinc supplementation is recommended in all acute diarrheas in children from developing countries. We aimed to assess whether zinc supplementation would be equally effective against all the common organisms associated with acute diarrheas. We used data on 801 children with acute diarrhea recruited in a randomized, double blind controlled trial (ISRCTN85071383) of zinc and copper supplementation....

Zinc deficiency during pregnancy has been related to adverse pregnancy outcomes. However, the results of zinc-supplementation trials have not been consistent in improvement of pregnancies outcomes. This study was undertaken to investigate whether zinc supplementation was associated with pregnancy complications in Iranian women during the last 2 trimesters. It also assessed the anthropometric me...

Epidemiologic studies suggest that zinc deficiency may be associated with increased risk of cancer. We investigated the effects of zinc picolinate supplementation on the development of leiomyomas, malondialdehyde (MDA), 8-isoprostane, 4-hydroxyalkenal (HAE), and 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels, and heat shock protein 70 (Hsp70) expression in Japanese quails. One hundred fifty quails...

Zinc is an essential element that facilitates coordination of immune activation during the host response to infection. We recently reported that zinc deficiency increases systemic inflammation, vital organ damage, and mortality in a small animal model of sepsis. To investigate potential mechanisms that cause these phenomena, we used the same animal model and observed that zinc deficiency increa...
