Objective: Biological agents represent a major advance in the treatment of moderate-to-severe plaque psoriasis. However, variations of efficiency, safety and costs of treatments make it difficult to select the drug. This study aims to update the cost per response of biological agents available in the Health Procedures and Events Roll (ROL) of the National Supplementary Health Agency (ANS). Methods: A cost-per-response analysis was used to assess the cost per outcome of Psoriasis Area and Severity Index (PASI) 90. Results were presented for the first year (I), which comprises induction and maintenance for 52 weeks and a fixed budget scenario analysis. Treatment costs were calculated based on the prices of the 2021 Medicines Market Regulation Chamber Table. Results: Analysis of year I, guselkumab showed the best result for cost per cost (R$ 130,467) PASI 90, followed by ixekizumab, ustekinumab, secukinumab, adalimumab, infliximab, and etanercept. In the fixedbudget analysis, guselkumab is the therapy capable of successfully treating (PASI 90) the largest number of patients. Conclusion: From the perspective of the Supplementary Health System in Brazil, guselkumab showed the best cost per response PASI 90, thus being the most cost-effective therapy in the treatment of moderate to severe plaque psoriasis available in the Brazilian ROL.

Cost-effectiveness of moderate-to-severe psoriasis biologic treatments in Brazilian private healthcare system: cost-per-responder results derived from a network metanalysis / Custo-efetividade do tratamento biológico para psoríase moderada a grave no sistema brasileiro de saúde suplementar: resultados de custo por resposta obtidos por meio de uma metanálise em rede

Objective: To assess the cost-per-responder (CpR) of biologic therapies available in Brazil to treat moderate-to-severe plaque psoriasis (PsO) from the private healthcare system's perspective. Methods: Number needed to treat (NNT) and (CpR) analyses were performed to evaluate biologic therapies' cost-effectiveness for moderate-to-severe PsO available in Brazil. The effectiveness of biologic treatments for moderate-to-severe PsO was assessed based on a previously published metanalysis, which included studies considering PsO patients and outcomes of interest (PASI 75, 90, and 100). The clinical efficacy data in terms of estimated NNT based on the network metanalysis (NMA) results were combined with drug treatment costs to determine the CpR for each treatment arm in 3-time horizons: the primary response period, 1-year, and 2-years. Results: Risankizumab was the most cost-effective option when NMA base case scenario data was used to calculate NNT in all PASI response for both the primary response period and 1- and 2-years follow-up durations. Differences in CpR between risankizumab and other biologic drugs increased with more significant PASI improvements. CpR sensitivity analysis also confirmed these findings, indicating that risankizumab has a better performance for PASI 100, and both risankizumab and guselkumab are very similar in terms of cost per additional PASI 75 and PASI 90 responder. Conclusions: Risankizumab was estimated to have a lower cost per PASI 75, 90, and 100 responders in most simulated scenarios (primary response period [12-16 weeks], 1-year and 2-years), among the evaluated biologic therapies.

Objetivo: Avaliar o custo por respondedor (CpR) das terapias biológicas disponíveis no Brasil para tratamento da psoríase em placas (PsO) moderada a grave, na perspectiva do sistema brasileiro de saúde suplementar. Métodos: Foram realizadas análises de número necessário para tratar (NNT) e CpR para avaliar o custo-efetividade das terapias biológicas para PsO moderada a grave disponíveis no Brasil. A eficácia foi avaliada por meio de dados de uma metanálise em rede (NMA), que incluiu estudos considerando pacientes com PsO moderada a grave e os desfechos de interesse (PASI 75, 90 e 100). Dados de eficácia em termos de NNT foram combinados com custos do tratamento medicamentoso para determinar o CpR para cada braço de tratamento em três horizontes temporais: período de resposta primária, 1 ano e 2 anos. Resultados: Risanquizumabe foi mais econômico quando utilizados os dados do caso-base para calcular o NNT, considerando todos os escores PASI para o período de resposta primária e em 1 e 2 anos. As diferenças no CpR entre o risanquizumabe e os outros medicamentos biológicos aumentaram com maiores ganhos de PASI. O CpR calculado pela análise de sensibilidade confirmou esses achados, indicando que risanquizumabe tem um melhor desempenho para PASI 100, e risanquizumabe e guselcumabe são muito semelhantes em termos de CpR por PASI 75 e PASI 90 adicionais. Conclusões: Risanquizumabe apresentou um custo mais baixo por respondedor PASI 75, 90 e 100 na maioria dos cenários analisados (período de resposta primária [12-16 semanas], 1 ano e 2 anos), entre as terapias biológicas avaliadas.

Consensus on the treatment of hidradenitis suppurativa - Brazilian Society of Dermatology

Abstract: Hidradenitis suppurativa is a chronic immune mediated disease of universal distribution that causes great damage to the quality of life of the affected individual, whose prevalence is estimated at 0.41% in the Brazilian population. The objective of this work was update on physiopathogenesis, diagnosis and classification of hidradenitis suppurativa and to establish therapeutic recommendations in the Brazilian reality. It was organized as a work group composed of eight dermatologists from several institutions of the country with experience in the treatment of hidradenitis suppurativa and carried out review on the topic. Recommendations were elaborated and voted by modified Delphi system and statistical analysis of the results was performed. The Brazilian consensus on the clinical approach of hidradenitis suppurativa had the support of the Brazilian Society of Dermatology.

Diagnosis and underdiagnosis of comorbidities in psoriasis patients - need for a multidisciplinary approach

Abstract BACKGROUND: Psoriasis is an immune-mediated disease that manifests predominantly in the skin, although systemic involvement may also occur. Although associated comorbidities have long been recognized and despite several studies indicating psoriasis as an independent risk factor for cardiovascular events, little has been done in general medical practice regardind screening. In the United States, less than 50% of clinicians are aware of these recommendations. OBJECTIVE: To identify the prevalence of these comorbidities in 296 patients followed up at a university dermatology clinic. METHODS: Systematically investigated comorbidity frequencies were compared with general practitioners' registry frequencies. Clinical features correlated with comorbidities were also investigated. RESULTS: High prevalences of systematically investigated comorbidities such as hypertension (30%) and dyslipidemia (26.5%) were documented. Conversely, data from general practitioners' records showed that 33% of dyslipidemia cases were undiagnosed and indicated possible underdiagnosis of some comorbidities. Furthermore, an association was found between: the number of comorbidities and psoriasis duration, age and high body mass index an association was found between the number of comorbidities and psoriasis duration, age, high body mass index, waist circumference or waist-to-hip ratio. (p<0.05). CONCLUSION: Disease duration, age and high body mass index, waist circumference or waist-to-hip ratio are possible criteria for choosing which patients should be screened for comorbidities. Underdiagnosis of comorbidities by general practitioners highlights the need for a multidisciplinary approach in psoriasis management.

Psoriasis: classical and emerging comorbidities

Psoriasis is a chronic inflammatory systemic disease. Evidence shows an association of psoriasis with arthritis, depression, inflammatory bowel disease and cardiovascular diseases. Recently, several other comorbid conditions have been proposed as related to the chronic inflammatory status of psoriasis. The understanding of these conditions and their treatments will certainly lead to better management of the disease. The present article aims to synthesize the knowledge in the literature about the classical and emerging comorbidities related to psoriasis.

Você conhece esta síndrome? / Do you know this syndrome?

A paquioníquia congênita é uma rara genodermatose da ceratinização, primeiramente descrita em 1906 por Jadassohn e Lewandowsky. Além de pouco conhecida, a variabilidade fenotípica e as formas oligossintomáticas dificultam o diagnóstico. Relatamos uma família com três gerações afetadas, até recentemente sem diagnóstico. A busca ativa por casos familiares em pacientes com quadro suspeito e a identificação de manifestações peculiares de seus subtipos, como esteatocistoma múltiplo, permitem diagnóstico clínico precoce. Além disso, oportunizam a orientação familiar e de prognóstico ao portador.

Pachyonychia Congenita is a rare genodermatosis of keratinization, first described in 1906 by Jadassohn and Lewandowsky. Besides not being well known, phenotypic variability and oligosymptomatic subtypes make the diagnosis difficult. We report a family with three generations affected, until recently not diagnosed. The active search for familial cases in patients with suspicious manifestations and identification of peculiar characteristics of its subtypes, as multiplex steatocystoma, provide early clinical diagnosis. In addition, nurture the family counseling and informations about prognosis.

Psoríase e obesidade: revisão de literatura e recomendações no manejo: [revisão] / Psoriasis and obesity: literature review and recommendations for management: [review]

Estudos recentes demonstram uma relação entre obesidade e inflamação crônica, confirmada através da associação de níveis elevados de fator de necrose tumoral alfa (TNF-±), interleucina seis (IL-6) e proteína C reativa, com aumento do índice de massa corporal (IMC). O estado inflamatório, nos indivíduos obesos, poderia contribuir para o desenvolvimento ou agravamento da psoríase. Fenômenos análogos já foram descritos, em outras doenças inflamatórias crônicas, como a artrite reumatóide e doença de Chrõn. Estudos epidemiológicos mostram uma prevalência elevada de comorbidades cardiovasculares, secundárias às alterações metabólicas, associadas à psoríase e obesidade. Permanecem ainda não elucidados alguns aspectos desta associação, como: o impacto da obesidade (nas formas clínicas da dermatose, na associação com comorbidades e na resposta ao tratamento).

Recent studies have found a relationship between obesity and chronic inflammation, confirmed by the association of high levels of tumor necrosis factor (TNF-_), interleukin six (IL-6,) and reactive C-protein with an increase in body mass index (BMI). In obese individuals, this inflammatory condition could contribute to the development or aggravation of psoriasis. Analogous phenomena have already been described in other inflammatory chronic diseases, such as rheumatoid arthritis and Crohn's disease. Epidemiological studies have identified a high prevalence of cardiovascular comorbidities, secondary to the metabolic alterations associated with psoriasis and obesity. A few aspects of this association remain unclear, such as the impact of obesity in the clinical forms of dermatoses, in the response to treatment, and its relationship with comorbidities.
