Diabetes mellitus, Fasting blood sugar, Psoriasis, Pearson co-relation coefficient


Background: Present study was done with objectives to study the co-relation between PASI and Fasting blood sugar (FBS) levels in psoriatic patients with diabetes mellitus and to study the association between duration of topical steroid therapy and Fasting blood sugar (FBS) levels.

Methods: Present study was conducted in the 26 patients at the Department of Dermatology at a tertiary care centre in Bhuj, Gujarat. A detailed history on the type of psoriasis, duration, associated co-morbid conditions and details of topical steroid therapy was obtained from all patients. They were examined in detail and assigned a PASI score to assess the severity of psoriasis. Patients with nail involvement were scored using N NAIL tool. Fasting blood sugar levels were noted in patients with Diabetes.

Results: Age of patients ranged from 15 years to 72 years. The different types of psoriasis observed were palmoplantar psoriasis-14 (50%), and chronic plaque psoriasis - 11. The joint was involved in 7 patients while 19 did not have joint involvement. The Pearson co-relation coefficient between PASI and FBS was 0.60 and p value was 0.001. The Pearson co-relation coefficient between duration of topical steroid therapy and FBS was 0.15, and p value was 0.50.

Conclusions: A statistically significant positive correlation between PASI and FBS was noted in this study. The duration of topical steroid therapy was not associated with significant changes in FBS in psoriatic patients with diabetes mellitus.
