Background: The Psoriasis Registry (PsorReg) was created by the Psoriasis Foundation of the Philippines with the goal of assessing the true magnitude of psoriasis in Davao City.

Objectives: To determine the demographic and clinical profiles of Filipino patients enrolled in PsorReg.

Methods: Cross-sectional study among adult patients enrolled in PsorReg.

Results: A total of 131 patients were included in the study. Mean age was 43.89 ± 15.8 years old. Chronic plaque psoriasis (96.2%) was the most common clinical pattern. 63.4% had nail involvement, while 35.1% had psoriatic arthritis. BMI was normal in 51.1% of patients. Common co-morbidities were hypertension (19.1%), diabetes (10.7%), and dyslipidemia (9.2%). Most common treatment were topical medications, while biologics were the least common. 42.7%, 49.6% and 37.4% had moderate psoriasis using BSA, PASI, and PGA, respectively. Majority (47.3%) reported a large effect of psoriasis on their quality of life.

Conclusion: This study determined the demographic and clinical profiles of adult Filipino patients registered in PsorReg in Davao City.
