Abstract:

Introduction and Purpose: Vitamin D is closely linked with skin diseases due to its immune, anti-inflammatory and immunomodulatory effects. We did this study in order to determine the levels of vitamin D in our dermatological group and to evaluate the effect of vitamin D on different dermatological diseases. Method and Requirements: The medical records of adult patients who were monitored by other clinics for the vitamin D levels between January 2013 and December 2013 in our Hospital’s Biochemistry Laboratory were examined retrospectively. The demographic characteristics of patients, clinical and laboratory findings were analyzed in the SPSS 17 program. 487 of 548 patients (88.9 percent) are women, the average age is 42.24±13. 20 (18-65) years, the average level of vitamin D was 13.34±9.62 ng/ml. 60.2 percent of patients had other chronic diseases in addition. Seventy-nine patients (14.4 percent) had severe deficiency (<5 ng/ml), 368 patients (67.2 percent) had deficiency (5-20 ng/ml), 73 patients (13.3 percent) had insufficiency (21-29 ng/ml). Only 28 patients (5.1%) had sufficient levels of vitamin D (>30 ng/ml). Many of our patients have been diagnosed with at least one skin symptoms. The most common skin diseases in our patient group were dermatitis (%32.3), dermatofitosis (%19.1), kserosis (%16.9), acne vulgaris (%10.7), psoriasis (%5.6), bacterial and viral skin diseases (%5.6), seborrheic dermatitis (%5.2), hair and nails disorder (%4.3), bacterial disease (%2.5), rosacea (%2.18), pigmentation disorder (%2.2) and urticum (%2.0). The difference between these levels of vitamin D was statistically meaningless (p>0.05). The result: Vitamin D affects many skin diseases. The level of vitamin D in the dermatological patient group should be assessed.
