The role of vitamin A in immunity

Your interaction of effectiveness of vitamin A supplementation in children to address morbility.Indicate what possible reasons be for the current levels of effectiveness

Answer 1

Vitamin A is effective in morbidity reduction. The supplementation of vitamin A to children reduces the mortality risk from some ways of measles, diarrhea, malaria, and human immunodeficiency virus (HIV) infection. These are the effects that vitamin A imposes on immunity. The clinical experts have described the mechanisms of immunomodulatory of vitamin A in clinical trials. One can also relate the mechanisms with the results of clinical supplementation. The results of vitamin A on the morbidity from measles create production of the antibodies and the proliferation of lymphocytes. Again, vitamin A is responsible for the benefits of severe diarrhea. It is essential in sustaining mucosal epithelial integrity in the gut. On the other side, the increased T-cell lymphopoiesis also relates to the positive effects on children living with HIV. However, there is a lack of evidence on the explicit impact of supplementation of vitamin A on the production of cytokine or lymphocyte activation. Through other conditions, the supplementation of vitamin A to preschool children can improve the antibody response to some vaccines like diphtheria toxoids, tetanus, and measles. Vitamin A is essential in immune system development and plays the role of regulation in cellular immune responses and humoral immune processes. This vitamin has shown therapeutic impacts in the treatment of several infectious diseases.
