Prevalence of psoriasis and cutaneous mycoses: A descriptive study in Paraná, Brazil

The epidemiology of psoriasis and cutaneous mycoses is scarce in Brazil. Thus, this cross-sectional study aimed to characterize the distribution of these diseases in Paraná. Data was obtained from the Outpatient Information System (SIA - Sistema de Informações Ambulatoriais), between 2016 and 2020. The procedures were filtered by the International Classification of Diseases (ICD). A total of 201,161 outpatient procedures were registered for psoriasis and psoriatic arthritis. The distribution concerning gender was similar (50.93% feminine; 49.07% masculine). The mean age was 51.55 years. The most frequent procedure was methotrexate dispensing (23.17%), followed by acitretin (14.29%) and adalimumab (12.55%). Adjusting to total population, the prevalence of procedures was 0.35%. Regarding cutaneous mycoses, 1,756 procedures were registered. 65% of them referred to females. White race/color was predominant (82.97%). The mean age was 37.6 years. The distribution concerning age varied according to the type of mycosis. Medical appointments (48.92%) and surgical pathology exam/biopsy (38.71%) were the most frequent procedures. The prevalence of procedures was 0.004%. This is the first epidemiological study using SIA about the population affected by psoriasis, psoriatic arthritis, and cutaneous mycoses in a Brazilian state. We believe that these findings allow relevant contribution to science and public policies in Brazil.
