Dear Editor,
The elucidation of pathophysiological mechanisms and the development of new treatments for psoriasis require periodic updates in the publication of consensuses, algorithms and treatment guides.
In Brazil, the ethnic composition, increased longevity, in addition to climatic and insolation characteristics may imply unique epidemiological data and different regional prevalence rates of psoriasis, in addition to influence disease severity and therapeutic response. Recent data from the Brazilian Society of Dermatology estimate the prevalence of psoriasis in Brazil at 1.31%, with 1.15% (95% CI 0.90% to 1.43%) in women and 1.47% (95% CI 1.11% to 1.82%) in men (p = 0.22). An increase in the prevalence of psoriasis (p<0.01) was identified in relation to age groups, which was 0.58% (95% CI 0.31% to 0.84%) under the age of 30; 1.39% (95% CI 1.10% to 1.74%) between 30 and 60 years old; and 2.29% (95% CI 1.71% to 2.84%) in individuals over 60 years. The geographical regions of the country differed in terms of disease prevalence (p = 0.02), with higher indicators in the South and Southeast regions, in contrast to the Midwest, North and Northeast regions.11 Romiti R, Amone M, Menter A, Miot HA. Prevalence of psoriasis in Brazil – a geographical survey. Int J Dermatol. 2017;56:167–8.
In parallel, 73.4% of Brazilian patients with moderate to severe psoriasis report impaired health-related quality of life.22 Lopes N, Dias LLS, Azulay-Abulafia L, Oyafuso LKM, Suarez MV, Fabricio L, et al. Humanistic and economic impact of moderate to severe plaque psoriasis in Brazil. Adv Ther. 2019;36:2849–65.
The Brazilian Consensus on Psoriasis 2020 and the Treatment Algorithm of the Brazilian Society of Dermatology (SBD), created with the collaboration of experts from all regions of Brazil is shown below (Fig. 1).
Geographical distribution of Brazilian experts participating in the Brazilian Consensus on Psoriasis 2020.
In preparing this consensus, the stratification of the levels of evidence and their grade of recommendation was used, according to the project guidelines of the Brazilian Medical Association (AMB), described below:
Grade of recommendation and strength of evidence33 portalmedico.org [Internet]. Brasília: Conselho Federal de Medicina. [cited 2020 Sept 01]. Available from: http://www.portalmedico[.org.br/diretrizes/100_diretrizes/Texto_Introdutorio.pdf.

B: Experimental or observational studies of lower consistency.

C: Case reports (uncontrolled studies).

D: Opinion without critical evaluation consensus based, physiological studies or animal models.
In this document, we use the Delphi tool to obtain answers to non-consensual questions in the literature, through the anonymous collection of data among specialists on the subject. The Delphi method is defined as ‟a data collection technique used to obtain consensus from a group of experts on a particular subject”.44 Marques J, Freitas D. Método DELPHI: caracterização e potencialidades na pesquisa em Educação. Pró-Posições [Internet]. 2018;29(Aug):389–415. Thus, a new treatment flowchart for severe psoriasis was validated and strategies were defined for the migration of therapies, designed for adoption in the Brazilian public or private health context, based on hearing the opinions of experts engaged in these health systems (Fig. 2).
Algorithm for the Treatment of Severe Psoriasis of the Brazilian Society of Dermatology, 2020.
Two rounds were held with the participation of 66 dermatologists who authored this consensus, from all regions of the country, with experience in the treatment of psoriasis. The online voting system (Survey Monkey®) was used, and the agreement of at least 70% of the experts was considered a consensus. The data obtained were statistically analyzed. The sample was obtained by appointment and submitted to a randomness test, which resulted in the non-rejection of randomness, with a significance of 5%. The results are shown in Table 1.
Mediated by the Brazilian Society of Dermatology, this instrument represents progress in the standardization of conduct, whether in public or private care, based on what we have available or aspire for the treatment of severe psoriasis. The existence of dissensus stimulates further debate on controversial and unanswered topics in the medical literature.
The high percentage of agreement in the other topics provides subsidies to professionals working in the area for the best therapeutic choices, instead of decisions based solely on the prescriber’s experience. Such transparency is essential for everyone involved, whether managers of the supplementary health system or the Brazilian Unified Health System (SUS), physicians, patients, their families, and patient associations.55 Kea, Sun B, Chih-An.
