Aim: The aim of this study was to investigate the frequency of depressive symptoms in psoriasis vulgaris and lichen planus and to evaluate the relationship between the Beck depression scores and the Psoriasis Area and Severity Index (PASI) scores of subjects with psoriasis vulgaris.
Subjects: The study involved 120 subjects attending the dermatology clinic of Izmir Ataturk Training Hospital (Izmir, Turkey) and comprised 50 subjects with psoriasis vulgaris, 30 with lichen planus and 40 healthy control subjects.
Results: Subjects with psoriasis vulgaris, lichen planus and controls had depression scores of 58%, 53% and 20%, respectively. The Beck depression scores of patients with psoriasis vulgaris were significantly higher than those of the control group. The PASI scores showed a correlation with Beck depression scores. Smoking and drinking were very common in subjects with psoriasis vulgaris. There was no correlation between the duration of illness and depressive symptoms.
Conclusions: This study confirms the importance of depressive symptoms in two common dermatological diseases. It is important to recognize this association as it affects both clinical outlook and response to treatment.
