Effect of Vitamin D Supplementation on Inflammatory Markers

Effect of Vitamin D Treatment on Some Inflammatory Markers in Non-obese Lebanese Patients With Type 2 Diabetes

Previous studies have shown that improving vitamin D status among the elderly may lead to an improvement in some inflammatory markers, especially with patients with type 2 diabetes. The aim of our trial is study the effect of vitamin D supplementation on inflammatory markers in patients having type 2 diabetes.

Vitamin D was shown crucial for insulin secretion and glucose homeostasis. Furthermore, one of the markers of type 2 diabetes is low-grade inflammation, which can be the result of an elevated circulation of cytokines. High amounts of circulating inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) contribute significantly to insulin resistance in muscle and adipose tissues. The aim of this randomized, controlled, double blind study is to examine the effect of vitamin D supplementation on some inflammatory markers in older Lebanese patients having type 2 diabetes.
