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.

In this randomized, controlled, double blind study, participants were randomized (using the simple randomization method) to receive either a supplement of 10,000 IU of cholecalciferol (Euro-Pharm International, Canada) or a placebo tablet (containing microcrystalline cellulose: 66.3%, starch: 33.2%, magnesium stearate: 0.5%, per serving) to be taken 3 times a week for a period of six months

Neither the investigator nor the subjects were aware of the group allocation; the pharmacist (in charge of the placebo tablets as well as the packing and coding of the supplements) was the only person to know to which group each participant belonged.
