Abstract

Background: Psoriasis is one of the most common skin diseases in the general population. One of the treatments is narrowband ultraviolet B (NBUVB) therapy. While the efficacy of NBUVB therapy for the treatment of plaque and guttate psoriasis has been demonstrated by means of the Psoriasis Area Severity Index (PASI), a frequently used tool to assess disease severity, little has been done to determine the impact of the disease on quality of life. Objective: To evaluate the effects of phototherapy treatment on quality of life using a modified form of the Psoriasis Disability Index questionnaire (PDI). Material and Methods: The efficacy of NBUVB in the treatment of psoriasis was evaluated in 40 patients. The PASI and the PDI were used as objective and subjective measures of disease severity. They were administered before and after therapy. Results: The improvement following treatment was found to be significant regarding individual questions as well as categories of questions, on both the objective PASI and the subjective PDI. Conclusions: Both the PASI and the PDI documented significant improvement in the clinical and psychological status of the patients, reinforcing the view that NBUVB is effective for psoriasis.
