Serum levels of 25-hydroxy vitamin D in psoriatic patients

Studies have shown a relationship between vitamin d and psoriasis. we compared serum levels of vitamin d of 20 psoriasis patients and 20 controls. the median vitamin d level was 22.80 ± 4.60 ng/ml; the median in the cases was 23.55 ± 7.6 ng/ml,and in controls 22.35 ± 3.10 ng/ml (p = 0.73). only 2 cases and 4 controls had suffi cient levels of vitamin d,although without statistical signifi cance between the groups (p = 0.608). levels were lower in women with psoriasis compared with those in male patients (20.85 ± 6.70 x 25.35 ± 2.90 ng/ml,p = 0.03),a fi nding that was not observed among controls. © 2015 by anais brasileiros de dermatologia.
