Experience of living with psoriasis in Brazil: a Global Psoriasis Atlas online survey.

BACKGROUND

Psoriasis significantly burdens patients' lives, but there is limited data on this in Brazil.

METHODS

Between May 2022 and January 2023, we conducted a cross-sectional online survey of 563 Brazilian residents aged ≥18 years who had been diagnosed with psoriasis. Spearman's correlation (r) was used to test the correlation between self-assessed disease severity (Simplified Psoriasis Index [saSPI] extent score; range 0 [clear/minor] to 40 [widespread/severe]) and health-related quality of life (QoL, score of 1 means perfect health) and capability (ICECAP-A: score of 1 means full capability) measures. Multivariable linear regression was used to identify predictors of QoL and capability. A thematic analysis examined the free-text responses and identified common themes.

RESULTS

The mean age of participants was 42.1 ± 12.4 years, and over half had at least one other long-term condition. The mean QoL score was 0.59 ± 0.25, and the mean capability score was 0.71 ± 0.21. At the time of survey completion, over 80% of respondents reported some level of pain and/or discomfort, and 86% reported feeling anxious and/or depressed. The mean self-assessed saSPI was 7.8 ± 8.6, which negatively correlated with health-related QoL (r = -0.49, P < 0.05) and capability (r = -0.44, P < 0.05). Significant predictors of poorer QoL and reduced capability included high saSPI, number of psoriasis flares and comorbidities, female gender, Black ethnicity, and employment status (unemployed, long-term sick). Frequently reported areas that impacted patients were social stigma/prejudice, powerlessness, lack of education and public awareness, and difficulty obtaining appropriate care/treatment.

CONCLUSIONS

We found that the clinical manifestations, severity, and associated comorbidities of psoriasis negatively impacted health-related QoL and capability, along with feelings of stigmatization and barriers to specialist treatment. This highlights the need for better access to care and awareness of the disease to improve the lives of people living with psoriasis in Brazil.
