Unique psoriatic lesion versus multiple lesions

Abstract

Aim: To evaluate the number of lesions of psoriasis and to find risk factors for multiple lesions. Material and Methods: 1,236 patients (male 54.13%, female 45.87%) with psoriasis were seen over a period of 8 years in an Outpatient Clinic. Patients filled out questionnaires containing age at onset, number of lesions and location at the beginning of the disease, gender, type and localization of psoriasis at the time of clinical examination, psoriasis family history, previous treatment, comorbidities, and social status. Results: The number of psoriasis lesions correlates with: onset age of psoriasis (F=8.902, p=0.0029); age at the moment of clinical examination (F=8.902, p=0.0029); residence in rural area (χ2=8.589, p=0.00338, 95%CI); alcohol intake (χ2=16.47, p=0.00005, 95%CI); smoking (χ2=8.408, p=0.00373, 95%CI); occupation: workers/pupils/students (χ2=14.11, p=0.0069, 95%CI). Conclusions: There is a correlation between number of psoriatic lesions and some factors. Multiple lesions were observed in older patients, smokers and drinkers, coming from rural area and social active (workers and pupils/students). No correlation was statistically proved between number of lesions and gender, comorbidities and family history of psoriasis.
