A Study to Assess the Severity of Psoriasis in Brazilians Participants With Chronic Plaque-type Psoriasis

Assessment of Psoriasis Severity in Brazilians Patients With Chronic Plaque-type Psoriasis Attending Outpatient Clinics: a Multicenter, Observational, and Cross-sectional Study (APPISOT)

The purpose of this study is to assess the severity of plaque-type psoriasis (common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region) in brazilian participants with chronic plaque-type psoriasis.

This is a cross-sectional (studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time), observational (clinical study in which participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions), non-interventional, multicenter study (when more than one hospital or medical school team work on a medical research study). Participants with plaque psoriasis will be followed up at specialized dermatology centers. Participants will undergo assessment at a single time point and all assessments will be conducted on the same day. Information will be collected about disease severity/ socioeconomic variables and demographics; clinical characteristics; treatment (current and past procedures and therapies to treat psoriasis); quality of life; and comorbidities identified after plaque psoriasis was diagnosed. The information will be obtained from the medical records, as requested, and during the medical interviews. The primary objective of this study is to assess the severity of plaque-type psoriasis.
