Prevalence of zinc deficiency and immune response in short-term hemodialysis.

Zinc is an essential trace element for many biological functions, including immune functions. The mechanism by which zinc may affect the immune system is certainly multifaceted, due to zinc's widespread action on different enzymes, peptides, transcriptional factors and cytokines involved in the various physiological steps of immune development and reactivity. In this study, prevalence of zinc deficiency and alteration in complement system, immunoglobulins and T cell subsets depending on zinc levels were analyzed in short-term hemodialysis patients and compared with healthy controls.
