LEVELS OF 25-HYDROXYVITAMIN D IN PATIENTS WITH PSORIASIS- A CROSS SECTIONAL OBSERVATIONAL CASE- CONTROL STUDY

Abstract

Background: Psoriasis is a common, immunologically mediated, inammatory disease characterized by skin inammation, epidermal hyperplasia, and increased risk of painful and destructive arthritis and cardiovascular morbidity and psychosocial challenges. Recent studies have shown higher prevalence of vitamin D deciency in patients with psoriasis than in control groups. It has been recently discovered that, vitamin D has role in modulation of Type 1 helper T cell (Th1) pathway. Thus low levels of vitamin D is believed to have an important implication in pathogenesis of psoriasis. Aims and objectives: To determine the 25-hydroxyvitamin D status of patients with chronic plaque psoriasis in comparison with age and sex matched controls. Materials and Methods: Thirty consecutive consenting patients with chronic plaque psoriasis and 30 age and sex matched controls with minor dermatological diseases were recruited in this study. Results: The age of the subjects ranged from 18yrs to 62yrs. The number of males was more than females. The overall prevalence of vitamin D in the study sample was 75%. Eighty percent cases and 70% controls had deciency of vitamin D. This study reveals that, the mean vitamin D was 16.23ng/do in case group and 19.29ng/dl in control group. The mean vitamin D was less in the cases as compare to controls, but it was not statistical signicant. Conclusion: Due to high overall prevalence of vitamin D deciency in India, many of the cases and controls had shown deciency. Not statistically signicant difference could be established between cases and controls with respect to serum vitamin D levels.
