Impact of propylthiouracil on quality of life in psoriasis patients.

ABSTRACT

Background: Psoriasis greatly impacts the quality of life (QOL) of patients including several dermatological conditions that are listed in the Dermatology Life Quality Index (DLQI). Decrease in psoriatic lesion as measured by Psoriasis Area Severity Index (PASI) score is associated with improvement in QOL. Propylthiouracil (PTU) was found to be clinically efficient in clearing psoriatic lesions. Our objective is to find the extent of improvement in QOL in psoriatic patients treated with PTU. Materials and Methods:Twenty-three psoriatic patients who were taking 300 mg PTU/day were involved in the study. Clinical improvement was assessed by PASI score and QOL was assessed by DLQI questionnaire at baseline, 6 th and 12 th week of PTU treatment. Results: Psoriatic patients before treatment showed significantly increased DLQI score when compared with 6 and 12 weeks of PTU treatment which was found to be decreased significantly (P < 0.001) after PTU treatment. There was a positive correlation between DLQI and PASI score at all three intervals of treatment period at P < 0.001 (r = 0.793, r = 0.834, r = 0.801), respectively. Conclusion: Since PTU was found to improve the QOL of psoriasis patients, this study adds an advantage of using it as treatment option in psoriasis.
