Background:
Psoriasis, a common papulo-squamous disorder of the skin, is universal in occurrence and may interfere with the quality of life adversely. Whether extent of the disease has any bearing upon the patients' psychology has not much been studied in this part of the world.
Aims:
The objective of this hospital-based cross-sectional study was to assess the disease severity objectively using Psoriasis area and severity index (PASI) score and the quality of life by Psoriasis quality-of-life questionnaire-12 (PQOL-12) and to draw correlation between them, if any.
Materials And Methods:
PASI score denotes an objective method of scoring severity of psoriasis, reflecting not only the body surface area but also erythema, induration and scaling. The PQOL-12 represents a 12-item self-administered, disease-specific psychometric instrument created to specifically assess quality-of-life issues that are more important with psoriasis patients.PASI and PQOL-12 score were calculated in each patient for objectively assessing their disease severity and quality of life.
Results:
In total, 34 psoriasis patients (16 males, 18 females), of age ranging from 8 to 55 years, were studied. Maximum and minimum PASI scores were 0.8 and 32.8, respectively, whereas maximum and minimum PQOL-12 scores were 4 and 120, respectively. PASI and PQOL-12 values showed minimal positive correlation (r = +0.422).
Conclusion:
Disease severity of psoriasis had no direct reflection upon their quality of life. Limited psoriasis on visible area may also have greater impact on mental health.
