Vitamin A is required for maintenance of integrity of epithelial cells and its growth and differentiation, visual function, and the immune system [4]. Vitamin A deficiency leads to patchy keratinization of epithelial lining of the respiratory, genitourinary and gastrointestinal tracts [5], which acts as protective barriers against infections. The loss of intestinal epithelial integrity increases the likelihood of bacterial colonization and incidence of infections and septicemia, and it has also been shown that vitamin A supplementation in smaller or higher doses help repair the damaged mucosa during the convalescence stage [6-10]. Vitamin A deficiency state is worsened during acute infections that reduces the dietary intake and absorption, and increases excretion of vitamin A in urine [11]. The mortality in vitamin A deficiency is also related to reduced immune function [12], [13]. Vitamin A improves wound healing by mediating early inflammatory responses associated with influx of macrophages, enhanced fibroblast differentiation, and collagen accumulation [14].
