Psoriasis is a chronic autoimmune inflammatory skin and joint disorder in which environmental, and behavioral influences are involved and has a prevalence of 2-3% worldwide . Vitamin D plays an important role as a regulator of the immune system by acting on CD4+ T lymphocytes as well as on the production and action of several cytokines. Since there is compelling evidence that vitamin D functions in the establishment and/or maintenance of immunological self-tolerance, it was of interest to us to study the relationship between vitamin D and chronic plaque psoriasis. After getting IRB approval from the College of Medicine Ethical Committee, twenty eight (11 males and 17 females) and corresponding matching controls (18 males and 19 females) who consented were enrolled. The cases were examined clinically for severity of psoriasis. Serum levels of vitamin D, parathyroid hormone (PTH), calcium and phosphate were estimated for both cases and controls. There was no significant correlation between psoriasis severity and calcium or phosphate levels as compared to control patients who do not have the disease (Pearson's coefficient : 0.21, 0.17 respectively). On the other there was a decline in PTH levels, in comparison to control patients, but it was nearly significant. However, there was a significant correlation between psoriasis and serum vitamin D levels (P<0.001). The present study shows a significant negative correlation between vitamin D serum levels and psoriasis in our patients.
