PREVALENCE OF SEVER PSORIASIS AMONG ADULT PATIENT AT KING FAHD HOSPITAL OF THE UNIVERSITY (KFHU), KHOBAR, KSA 2018

Background: Psoriasis is the most common T helper 1 mediated inflammatory disease, affecting more than 125 million people worldwide [1]. About 60% of psoriasis patients suffer from moderate to severe disease, i.e. more than 10% of the body surface area is covered by psoriatic plaques [2]. Objectives: To assess the prevalence of sever psoriasis among adult patient at King Fahd Hospital of the University (KFHU), Khobar, KSA 2018 Method: A retrospective case-control study was done on 50 patients who suffered from psoriasis by utilizing the charts of patients who selected randomly by accessing to management report viewer records through information technology (IT) department in King Fahd Hospital of the University. Results: Our cohort included 50 patients with confirmed psoriasis. Psoriasis severity was determined in 35 patients (70%). The age of our cohort ranged from 15 to 72 years with the mean of 31.4 years. The statistical analysis reported a significant correlation between age and PASI score regarding to the severity (P-value= 0.033 and 0.000 respectively), also a significant correlation between gender regarding to the severity of psoriasis (P-value= 0.000). Regarding to the severity of psoriasis among the two studied groups showed a significant correlation between the number of patients with PASI score more than 10 and the occurrence of severe psoriasis (P-value=0.001) Conclusion: the prevalence of psoriasis was higher among females. The mean age of our cases was 31.4 years. Our study depends on the PASI score to recognize the severe cases of psoriasis where we classify them according to it. Smoking and arthritis are risk factors for severe psoriasis. Keywords: Psoraisis, Severe psoraisis, psoriasis area severity index (PASI)
