RESUMEN

The concept of "Cumulative Life Course Impairment" (CLCI) characterizes the set of factors harmful to the lives of patients resulting from the stigma and physical and psychological impairment associated with different chronic diseases, which can accumulate irreversibly over the course of patients lives. The sum of these factors often makes it impossible for these individuals to enjoy their lives fully, intensely and adequately. On the other hand, CLCI also incorporates coping strategies, including external factors and personality characteristics, which may act as modulating or protective factors of vulnerability to the CLCI. Although psoriasis is the most studied dermatological disease in relation to its impact on quality of life and CLCI, several other chronic inflammatory diseases such as atopic dermatitis, hidradenitis suppurativa, and alopecia areata have also been evaluated in relation to the magnitude of the damage to patients lives.

RESUMEN

INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic skin condition causing considerable distress. It impacts mobility, social interaction, and quality of life. In Brazil, there is a notable gap in epidemiological data and patient experiences regarding HS. METHODS: This study, spanning 2019 to 2022, employed netnography to probe the experiences of Brazilian patients with HS. This approach gleans insights from online interactions, offering a direct view into patients' lives. RESULTS: Notably, the data illuminated the challenges patients face, such as difficulties in obtaining a diagnosis and the complexities involved in managing a chronic, and often debilitating, condition. Furthermore, patients' experiences with various treatments, encompassing antibiotics, biologic agents, lifestyle alterations, surgical procedures, and alternative remedies, were also examined. CONCLUSION: By undertaking a longitudinal analysis of patient interactions, the study aimed to offer a richer understanding of HS, from its diagnosis to its treatment. It underscores the necessity for a more patient-centered approach when managing this condition. We hope that this enhanced understanding can facilitate better care for those affected by HS.

RESUMEN

Background: Hidradenitis suppurativa (HS) is a chronic skin condition. Its complexity and impact on patients highlight the need for multidisciplinary care that can address the physical, psychological, and social aspects. Centers of excellence can ideally provide the necessary infrastructure, resources, and expertise to effectively treat HS. However, there are still no consolidated models of centers of excellence in HS, and establishing their foundations is an intricate research challenge. Purposely, design and co-creation as innovation techniques are helpful approaches to this type of research. Methods: In this study, we conducted a co-creation with consensus among HS specialists to propose the criteria and requirements to establish outpatient centers of excellence of HS in Brazil. We followed a linear process with mixed methods in 6 stages. Results: The process resulted in 10 categories for establishing outpatient centers, including their respective requirements, rationale, and classification. The categories include onboarding and welcoming; infrastructure and procedures; infusion therapy; flows and referrals; staffing; disease management; metrics during diagnosis; metrics during treatment; awareness and advocacy; research and education. Discussion: The idealized outpatient centers can play a role in the complete multidisciplinary treatment for HS and advancing the science of healthcare services by providing a focus for research, training, and translation of findings into practice.

RESUMEN

OBJECTIVE: The 2021 Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations provide an evidence-based guide for selecting therapy based on the individual's disease features. Beyond the disease features and associated conditions (eg, uveitis and inflammatory bowel disease), comorbidities play an important role in selecting therapy for an individual patient. METHODS: We performed a systematic literature review. We examined the available evidence to inform treatment selection based on the presence or absence of comorbidities in psoriatic arthritis (PsA). RESULTS: Common comorbidities in PsA that may affect treatment selection include presence of baseline cardiovascular disease (CVD) or high risk for CVD, obesity and metabolic syndrome, liver disease, mood disorders, including depression in particular, chronic infections, malignancies, osteoporosis, and fibromyalgia and/or central sensitization. CONCLUSION: Comorbidities may influence both the effectiveness of a given therapy but also the potential for adverse events. It is important to assess for the presence of comorbidities prior to therapy selection.

RESUMEN

Objetivo: Os agentes biológicos representam um grande avanço no tratamento da psoríase em placas moderada a grave. No entanto, variações de eficácia, segurança e custos dos tratamentos podem dificultar a escolha do agente terapêutico. Este estudo teve como objetivo atualizar o custo por resposta dos agentes biológicos disponíveis para psoríase no ROL de Procedimentos e Eventos em Saúde (ROL) da Agência Nacional de Saúde Suplementar (ANS). Métodos: Uma análise de custo por resposta foi utilizada para avaliar a razão de custo pelo desfecho Índice de Gravidade e Área da Psoríase (PASI) 90. Os resultados foram apresentados para o primeiro ano (ano I), que compreende a fase de indução e a fase manutenção até completar 52 semanas e foi realizada uma análise da efetividade do tratamento num cenário de orçamento fixo. Os custos dos tratamentos foram calculados com base nos preços de fábrica (PF18%) da Tabela da Câmara de Regulação do Mercado de Medicamentos de junho de 2021. Resultados: Para o ano I, o guselcumabe apresentou melhor resultado para custo por resposta (R$ 130.467) PASI 90, seguido por ixequizumabe, ustequinumabe, secuquinumabe, adalimumabe, infliximabe e etanercepte. No cenário com orçamento fixo, o guselcumabe demonstrou ser o agente capaz de tratar com sucesso (PASI 90) o maior número de pacientes. Atualização do custo-efetividade por resposta para psoríase em placas moderada a grave. Conclusão: Sob a perspectiva do Sistema de Saúde Suplementar do Brasil, o guselcumabe apresentou o melhor custo por resposta PASI 90, sendo, assim, a terapia com melhor custo-efetividade no tratamento da psoríase em placas moderada a grave disponível no ROL.

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.

RESUMEN

BACKGROUND: Generalized pustular psoriasis (GPP) is a rare and severe phenotype of psoriasis characterized by sudden outbreak of widespread coalescent sterile pustules associated with a spectrum of systemic symptoms. OBJECTIVE: We aimed to describe the epidemiology and treatment of GPP in Brazil from the public health care system perspective. METHODS: This was a retrospective public claims database study, using outpatient and inpatient databases, with information from January 2018 to August 2020, based on records of health resource utilization by patients with GPP. Outpatient treatment regimens and fatal inpatient outcomes were described. RESULTS: In total, 1458 outpatients of all ages were identified, of whom 53% were women. We estimated the GPP prevalence in Brazil to be between 0.7 and 0.9 per 100,000. Acitretin was the most commonly dispensed drug. Of all the outpatients, 769 outpatients could be tracked in the inpatient database, and 151 had hospital admissions during the study period. Of them, 5.3% had a fatal outcome during hospitalization. A primary skin condition or an infection was the most frequent hospitalization cause. LIMITATION: The International Classification of Diseases codes for GPP and psoriasis have not been previously validated in this context. CONCLUSION: GPP is a rare disease in Brazil and affects individuals of all ages and both sexes. Hospitalizations and disease-related deaths highlight the need for its prompt diagnosis, close medical follow-up, and effective treatment.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

In the absence of ideal biomarkers, the research for clinical markers correlated to the severity of psoriasis and/or its comorbidities becomes crucial. Recently, studies have shown positive correlation between body mass index and prevalence and severity of psoriasis. Abdominal circumference showed stronger correlation with disease severity than body mass index. We evaluated the waist-to-height ratio in a sample of 297 adult patients with psoriasis and observed that it has a significant correlation with body mass index and PASI, and together with body mass index allows the identification of central obesity, reducing its subdiagnosis.

RESUMEN

BACKGROUND: Antitumor necrosis factor (anti-TNF) agents are a well-established treatment for various medical conditions, including psoriasis and psoriatic arthritis. However, anti-TNF agents may themselves induce psoriasis in some patients. METHODS: The authors report two cases of patients with severe and refractory infliximab-induced psoriasis. RESULTS: The patients had good clinical responses after switching to another TNF blocker. CONCLUSION: For severe cases, infliximab withdrawal combined with conventional immunosuppressive psoriasis drugs or with adalimumab may be a therapeutic option.

RESUMEN

BACKGROUND: Obesity has been associated with the severity of psoriasis, but this relationship is not completely understood. OBJECTIVES: This study aimed to evaluate associations between the severity of psoriasis and weight excess as determined using a variety of parameters. METHODS: A cross-sectional study was performed in 296 psoriasis patients. Their body mass index (BMI), waist circumference (WC), and waist : hip ratio (WHR) values were compared with results on a psoriasis area severity index (PASI). RESULTS: The frequency of severe psoriasis was higher in men (P < 0.05). Direct correlations were established between PASI scores and each of BMI (R = 0.0154, P = 0.01), WC (R = 0.207, P = 0.001), and WHR (R = 0.164, P = 0.007). CONCLUSIONS: This study extends previous reports of an association between psoriasis and obesity and shows a direct correlation between obesity as measured according to different parameters and psoriasis severity.

RESUMEN

Psoriatic arthritis (PsA) is a chronic inflammatory spondyloarthritis that occurs in combination with psoriasis. The exact prevalence of PsA is unknown, and its pathogenesis has not yet been fully elucidated. Genetic, environmental, and immunologic factors have all been implicated. The appearance of arthritis might precede, succeed or occur concomitant with skin lesions. PsA is sometimes considered a benign form of arthritis, but it affects patient quality of life and also causes functional impairment. Up to 20% of affected patients exhibit extremely destructive and disfiguring forms of the disease, and PsA is associated with increased mortality. The treatment of PsA aims to provide relief from signs and symptoms of the disease, prevent structural damage to joints, improve patient quality of life and decrease mortality. The choice of treatment depends on the severity of clinical presentation. The use of immunobiological agents is restricted to cases that do not respond to conservative treatment.
