RESUMO

There is a need for new and effective topical treatment options for psoriasis. Recent phase I and II clinical trials have demonstrated efficacy of the novel nonsteroidal drug tapinarof to treat mild to moderate plaque psoriasis. Tapinarof is an aryl hydrocarbon receptor (AHR) agonist that induces antioxidant, immunomodulatory and epidermal differentiation regulation pathways. In this review, we examine the current preclinical and clinical studies with a focus on the mechanism of action, pharmacokinetics, safety and efficacy of tapinarof to treat psoriasis.

RESUMO

AIM: To assess C-reactive protein to albumin ratio (CAR) before and after treatment with biological agents in patients with psoriasis to determine whether CAR can be used as an inflammation biomarker. METHODS: Medical records of patients with psoriasis treated with biological agents at the Department of Dermatology, Gazi University Hospital were retrospectively evaluated between June 2018 and August 2019. The patients were divided into four groups based on the type of treatment (adalimumab, ustekinumab, infliximab, secukinumab). CAR was evaluated before and three months after treatment. RESULTS: The study enrolled 157 patients with psoriasis vulgaris (91 male) aged between 18 and 85. CAR significantly decreased in all treatment groups (adalimumab group P<0.001; ustekinumab P=0.006; infliximab P=0.007; secukinumab P<0.001). The most prominent decrease in CAR was observed in patients treated with secukinumab (median CAR before treatment 1.52 [1.01-3.04] and after treatment 0.84 [0.62-0.99]). CONCLUSION: CAR may be a good indicator of systemic inflammation in psoriasis patients treated with biological agents.

RESUMO

Pioglitazone may have potential benefits in the treatment of cutaneous and metabolic derangements of psoriasis, but its role in the treatment of psoriasis remains in debate. We therefore conducted a meta-analysis to evaluate the clinical efficacy and safety of pioglitazone in psoriasis vulgaris (PsV).We performed a comprehensive search in database of PubMed, Web of Science, Cochrane library, Embase and China National Knowledge Infrastructure (CNKI), and Wan fang database through March 2019 to identify eligible studies. Randomized controlled trials that have evaluated the effect and safety of pioglitazone in PsV were included. Treatment success was defined as ≥75% reduction in psoriasis area and severity index (PASI) score after treatment. Weighted mean differences (WMD), relative risks (RRs) and the corresponding 95% confidence intervals (CIs) were pooled to compare the clinical efficacy and safety between different groups.Six randomized controlled trials (n = 270) were included. Meta-analysis showed that pioglitazone was associated with a remarkable reduction in PASI score in patients with PsV (weight mean difference: 2.68, 95% CI 1.41-3.94, P < .001). The treatment success rate in the pioglitazone group was higher than in the control group (RR 3.60, 95 CI 1.61-8.01, P < .001). Compared with control group, pioglitazone was not related to a pronounced increase in total adverse events (RR 1.180, 95 CI 0.85-1.63, P = .33). Moreover, the risk of common adverse events in the 2 groups were similar, such as elevated liver enzyme, fatigue, nausea, weight gain.This meta-analysis suggested pioglitazone is an effective and safe drug in the treatment of patients with PsV.

RESUMO

Introduction: Methotrexate exhibits poor cutaneous bioavailability and systemic side effects on topical administration, so there is an unmet need for a novel carrier and its optimized therapy. Methotrexate-loaded nanostructured lipid carriers (MTXNLCs) were formulated and characterized to determine in vitro drug release and evaluate the role of MTXNLC gel in the topical treatment of psoriasis. Methods: A solvent diffusion technique was employed to prepare MTXNLCs, which was optimized using 32 full factorial designs. The mean diameter and surface morphology of MTXNLCs was evaluated. The crystallinity of lyophilized MTXNLCs was characterized by differential scanning calorimetry (DSC) and powder X-ray diffraction (XRD). MTXNLCs were integrated in 1% w/w Carbopol 934 P gel base, and in vitro skin deposition studies in human cadaver skin (HCS) were carried out. Results: The optimized MTXNLCs were rod-shaped, with an average particle size of 253 ± 8.65 nm, a zeta potential of -26.4±0.86 mV, and EE of 54.00±1.49%. DSC and XRD data confirmed the formation of NLCs. Significantly higher deposition of MTX was found in HCS from MTXNLC gel (71.52 ±1.13%) as compared to MTX plain gel (38.48±0.96%). In vivo studies demonstrated significant improvement in therapeutic response and reduction in local side effects with MTXNLCs-loaded gel in the topical treatment of psoriasis. Anti-psoriatic efficacy of MTXNLCs 100 ug/cm2 compared with plain MTX gel was evaluated using imiquimod (IMQ)-induced psoriasis in BALB/c mice. The topical application of MTXNLCs to the mouse ear resulted in a significant reduction of psoriatic area and severity index, oxidative stress, inflammatory cytokines like TNF-α, IL-1ß, and IL-6 and IMQ-induced histopathological alterations in mouse ear samples. Conclusion: Developed formulation of MTXNLC gel demonstrated better anti-psoriatic activity and also displayed prolonged and sustained release effect, which shows that it can be a promising alternative to existing MTX formulation for the treatment of psoriasis.

RESUMO

Introdução: A psoriase e uma doenca inflamatoria sistemica cronica com manifestacoes frequentemente cutaneas, ungueais e articulares, cursando normalmente de forma remitente e recorrente. Com distribuicao similar entre os sexos e ocorrencia mais frequente entre a terceira e quarta decadas de vida, sua prevalencia no Brasil e estimada entre 1,31% a 2,5%. No SUS, os pacientes possuem garantia de acesso aos tratamentos preconizados em diretrizes terapeuticas, onde o tratamento e iniciado com farmacos por via topica, seguidos de outras opcoes como a fototerapia, medicamentos por via oral e injetaveis de acordo com a gravidade. Os fármacos sistemicos indicados em primeira linha incluem o metotrexato, acitretina e ciclosporina. Em caso de falha destes medicamentos, estao disponiveis outros, quatro biologicos, sendo dois da classe dos anti-TNF (adalimumabe e etanercepte) e dois medicamentos anti-interleucinas, um da classe dos anti-IL12/23 (ustequinumabe) e outro da classe dos anti-IL17 (secuquinumabe). PERGUNTA: O uso de ixequizumabe e eficaz, seguro e custo-efetivo para a segunda etapa de tratamento biologico de pacientes adultos com psoriase em placas moderada a grave, quando comparado as terapias sistemicas biologicas aprovadas pela Conitec nessa etapa de tratamento (ustequinumabe e secuquinumabe)? TECNOLOGIA: Ixequizumabe. EVIDÊNCIAS CIENTÍFICAS: Com uso de meta-analise em rede, uma revisao sistematica da Colaboracao Cochrane teve o objetivo de comparar e hierarquizar os agentes sistêmicos convencionais e biologicos para pacientes com psoriase moderada a grave de acordo com sua eficacia e seguranca. Apos buscas amplas, a revisao incluiu 140 estudos avaliando 19 diferentes tratamentos com um total de 51.749 participantes randomizados e idade media de 45 anos. Todos os resultados (exceto dois estudos) foram limitados a fase de inducao (de 8 a 24 semanas apos a randomizacao). Problemas com o cegamento dos pacientes e envolvidos (performance) e dos avaliadores foram os riscos mais frequentemente identificados. Dentre outros riscos, ressalta-se que a maioria dos estudos declarou financiamento por uma empresa farmaceutica e 22 estudos nao relataram a fonte de financiamento. No desfecho de PASI 90, o resultado da meta-analise em rede destaca que ambos os medicamentos anti-IL17 (ixequizumabe e secuquinumabe) foram significativamente mais efetivos que o ustequinumabe e o adalimumabe. No desfecho do PASI 75 a classe de medicamentos anti-IL17 tambem foi associada a uma maior probabilidade de atingi-lo em comparacao as outras classes. Em relação ao desfecho de eventos adversos graves (EAG), os medicamentos infliximabe, ixequizumabe e secuquinumabe apresentaram maior risco de EAG do que o metotrexato. Associacoes estatisticamente significativas foram encontradas demonstrando que os anti-IL17 apresentam maior risco de eventos adversos em geral em comparacao aos anti-IL23 e anti-IL12/23. O nível de certeza das evidencias de efetividade do ixequizumabe foi considerado moderado (com reducoes devido a inconsistencias) e no desfecho de eventos adversos graves foi considerado moderado (com reducoes devido a imprecisao). AVALIAÇÃO ECONÔMICA: Considerando que a "analise de custo por resposta" enviada pelo demandante carece do rigor metodologico das avaliacoes economicas completas, foi elaborado um novo modelo de custo-efetividade contemplando todas as opcoes disponiveis no SUS e em analise pela Conitec para o tratamento da psoriase moderada a grave. Seguindo a proposta do modelo bastante difundido e concebido por pesquisadores da Universidade de York, foi construido um modelo de arvore de decisao (periodo de inducao) acoplado a um modelo de Markov (periodo de manutencao), buscando analisar os custos e consequencias em termos de anos de vida ajustados pela qualidade (QALY) com as seguintes estrategias de tratamento: ixequizumabe; secuquinumabe; ustequinumabe; risanquizumabe; adalimumabe e infliximabe. Com os resultados do modelo, a partir da analise da fronteira de eficiencia, observa-se a dominancia (efetividade menor e maior custo) dos tratamentos com infliximabe (dominância simples) e secuquinumabe (dominancia estendida) pelos tratamentos com adalimumabe, ustequinumabe e ixequizumabe. O tratamento com risanquizumabe apresenta um valor de efetividade limitrofe com o ixequizumabe, contudo, a um custo muito superior. Ao realizar a analise de limiar por meio da abordagem da fronteira de eficiencia, observa-se que seria necessario que o preco dos medicamentos secuquinumabe, ixequizumabe e risanquizumabe tivessem uma reducao de preco de pelo menos 10,74%, 9,08% e 55,09%, respectivamente, para serem considerados custo-efetivos. Na curva de aceitabilidade de acordo com o escalonamento progressivo da disposicao a pagar, os tratamentos com maior probabilidade de serem custoefetivos foram o adalimumabe, seguido do ustequinumabe e, por fim, o ixequizumabe. AVALIAÇÃO DE IMPACTO ORÇAMENTÁRIO: O demandante encaminhou uma analise de impacto orcamentario que, apos analise critica, considerou-se um modelo adequado e coerente com discussoes anteriores na Conitec. Todavia, alguns de seus dados foram revisados e atualizados resultando em novos valores de impacto. Em sua versao original, o demandante apresentava uma economia de R$ 14.322.953,00. Contudo, apos as atualizacoes dos custos e da taxa de falha ao adalimumabe descritas, estima-se um impacto incremental de R$ 4.052.249,89 ao longo de cinco anos. MONITORAMENTO DO HORIZONTE TECNOLÓGICO: Foram detectadas no horizonte sete potenciais tecnologias para pacientes adultos com psoriase moderada a grave, apos falha da primeira etapa da segunda linha de tratamento: apremislate, bimequizumabe, BMS-986165, brodalumabe, guselcumabe, miriquizumabe e piclidenoson. CONSIDERAÇÕES: A partir das estimativas de efetividade comparativa disponiveis por meio de meta-analises em rede, e possivel observar que o ixequizumabe e o secuquinumabe foramsignificativamente mais efetivos que o ustequinumabe e o adalimumabe. Em relacao a seguranca, observam-se associacoes estatisticamente significativas de que os anti-IL17 apresentam maior risco de eventos adversos em geral em comparacao aos anti-IL23 e anti- IL12/23. O nivel de certeza das evidencias de efetividade foi considerado moderado tanto nos desfechos de efetividade e seguranca para o ixequizumabe. Na curva de aceitabilidade de acordo com a disposicao a pagar, os tratamentos com maior probabilidade de serem custoefetivos foram o adalimumabe, seguido do ustequinumabe e, por fim, o ixequizumabe. Por meio de uma reducao plausivel de preco, e possivel que o ixequizumabe apresente um perfil de custoefetividade semelhante aos tratamentos mais eficientes disponiveis no SUS. Apos as atualizacoes do modelo de impacto orcamentario encaminhado, estima-se um impacto incremental de R$ 4.052.249,89 ao longo de cinco anos com a incorporacao do ixequizumabe ao SUS. RECOMENDAÇÃO PRELIMINAR: Pelo exposto, a CONITEC, em sua 85a reuniao ordinaria, no dia 04 de fevereiro de 2020, recomendou a nao incorporacao no SUS do ixequizumabe para o tratamento de pacientes adultos com psoriase moderada a grave, que tenham apresentado falha terapeutica, contraindicacao ou intolerancia ao adalimumabe. Considerou-se que, apesar do ixequizumabe estar associado a beneficios incrementais em termos de efetividade no tratamento da condicao clinica em analise, sua eficiencia (custo-efetividade) e inferior aos tratamentos ja disponiveis no SUS com base no preco proposto pelo fabricante. A materia foi disponibilizada em consulta publica. CONSULTA PÚBLICA: Foram recebidas 142 contribuicoes tecnico-cientificas e 280 contribuicoes de experiencia ou opiniao, sendo a maioria discordante da recomendacao preliminar da CONITEC. Apos analise do texto das contribuicoes, foram identificados pontos como necessidade de mais alternativas terapeuticas ou mecanismos de acao, superioridade dentre os tratamentos disponiveis, assim como foram apresentados novas propostas de preco e limitacoes da analise preliminar. O laboratorio fabricante ofereceu uma nova proposta de preco equivalente a reducao de 2,7% do preco proposto inicialmente. No modelo atualizado, apresenta-se como uma opcao mais custo-efetiva que o secuquinumabe, porem, menos custo-efetiva que o tratamento com a tecnologia também em analise risanquizumabe. Um novo modelo de impacto orcamentario tambem foi apresentado indicando uma reducao de gastos de ate R$ 37.955.681,00 ao longo dos 5 anos na ocasiao de incorporacao na mesma linha e indicacao do secuquinumabe. Apos apreciacao das contribuicoes encaminhadas pela Consulta Publica, incluindo o destaque para a superioridade em relacao ao adalimumabe e ustequinumabe, limitacoes dos modelos apresentados, experiencias profissionais e pessoais com o tratamento e as novas propostas de preco, o plenario da Conitec entendeu que nao houve argumentacao suficiente para alterar a recomendacao inicial desfavoravel a incorporacao, em relacao ao nivel de eficiencia do tratamento em analise (custo-efetividade), no contexto proposto no SUS. RECOMENDAÇÃO FINAL: Os membros da Conitec, presentes na 89a reuniao ordinaria, no dia 6 de agosto de 2020, deliberaram, por unanimidade, recomendar a nao incorporacao no SUS do ixequizumabe para o tratamento de pacientes adultos com psoriase moderada a grave, que tenham apresentado falha terapeutica, contraindicacao ou intolerancia ao adalimumabe. DECISÃO: Nao incorporar o ixequizumabe para tratamento de pacientes adultos com psoríase moderada a grave, que tenham apresentado falha terapeutica, contraindicacao ou intolerância ao adalimumabe, no ambito do Sistema Unico de Saude - SUS, conforme Portaria no 27, publicada no Diario Oficial da Uniao no 160, secao 1, pagina 117, em 20 de agosto de 2020.

RESUMO

INTRODUCCIÓN: Este documento técnico se realiza a solicitud del SIS-GREP. A. Cuadro clínico: La psoriasis es una enfermedad sistémica crónica que afecta al 3.2% de la población, se caracteriza por inflamación e induración epidérmica. Dentro de su patogenia se encuentran procesos mediados por el sistema inmune, en la que los cambios genéticos y epigenéticos resultan en un fenotipo de enfermedad caracterizada por una función inmune alterada, activación e hiperproliferación de queratinocitos, y el desarrollo de placas descamativas induradas y eritematosas. Entre el 20 y 30% de los pacientes con psoriasis asocian una artritis psoriásica (APs), la cual puede preceder, ser concomitante o posterior a las manifestaciones cutáneas de la psoriasis. B. Tecnología sanitária: Etanercept (ETN) fue el primer inhibidor de TNF-α que demostró una respuesta significativa en APs. El uso de ETN modula la respuesta biológica severa que es inducida o regulada por TNF, incluyendo la expresión de moléculas de adhesión responsables por la migración leucocítica, nivel sérico de citocinas (ej. IL-6) y niveles séricos de metaloproteinasas de la matriz. Se recomienda el uso de ETN en pacientes con APs para reducir los signos y síntomas, además de inhibir la progresión del daño estructural de la artritis activa, y mejorar la función física. OBJETIVO: Evaluar la eficacia y seguridad, así como documentos relacionados a la decisión de cobertura de etanercept para psoriasis de placa moderada a severa y artritis psoriásica. METODOLOGÍA: Se realizó una búsqueda en las principales bases de datos bibliográficas: MEDLINE, LILACS, COCHRANE, así como en buscadores genéricos de Internet incluyendo Google Scholar y TRIPDATABASE. Adicionalmente, se hizo una búsqueda dentro de la información generada por las principales instituciones internacionales de reumatología, y agencias de tecnologías sanitarias que realizan revisiones sistemáticas (RS), evaluación de tecnologías sanitarias (ETS) y guías de práctica clínica (GPC). RESULTADOS: Se identificaron una RS, cinco GPC y tres ETS. No se encontraron evaluaciones económicas de Perú o la región latinoamericana. CONCLUSIONES: La evidencia comparativa de ETN versus otros inhibidores TNF-α se basa en comparaciones indirectas. Una RS utilizando metaanálisis en red sugiere que adalimumab sería más eficaz que ETN en artritis psoriásica sin diferencias en los eventos adversos. Las 5 GPC seleccionadas consideran ETN como una opción de tratamiento en segunda línea y mencionan que la elección de medicamentos se debería hacer a través de criterio clínico. Una ETS peruana menciona que ETN es una mejor opción comparada con ustekinumab. Una ETS (España) mencionan a ETN como superior por sobre otros anti TNF-α mientras que otra ETS (Reino Unido) no la encuentra costo-efectiva para el manejo de pacientes con artritis psoriásica.

RESUMO

BACKGROUND: Knowledge regarding differences in care for psoriatic patients is limited. The aim of this study was to investigate factors influencing prescription of systemic treatments for patients with psoriasis with a special focus on socioeconomic factors. METHODS AND FINDINGS: This was a non-interventional, cross-sectional study, conducted in 18 Italian University and/or hospital centers with psoriasis-specialized units. Questionnaires evaluating demographic and socioeconomic characteristics were administered to participants. Overall, 1880 consecutive patients affected by mild-to-severe psoriasis were recruited. Univariate and multivariable logistic regression analyses of systemic therapy prescription, with a special focus on biologics, accounting for the above mentioned characteristics were performed. Our analysis showed that all analyzed patients' characteristics were significantly associated with biological therapy compared to non-biological systemic one. Particularly, women were less likely to receive biologics than men (OR = 0.66; 95% CI, 0.57-0.77). Elderly patients (≥65 years) and subjects with a BMI ≥30 had lower odds to receive biologics respect to adults (≥35-64 years) (OR = 0.33; 95% CI, 0.25-0.40), and subjects with BMI≥25<30 (OR = 0.64; 95% CI, 0.53-0.77), respectively. Northern and Southern patients were both less likely to receive biologics than Central patients (OR = 0.75; 95% CI, 0.63-0.89, and OR = 0.56; 95% CI,0.47-0.68, respectively). Lower economic profile and never reading books were both associated with decreased odds of receiving biological therapy. CONCLUSIONS: This study shows that sex, age, comorbidities, and socioeconomic characteristics influence the prescription of systemic treatments in psoriasis, highlighting that there are still unmet needs influencing the therapeutic decision-making process that have to be addressed.

RESUMO

The identification of disease alleles underlying human autoinflammatory diseases can provide important insights into the mechanisms that maintain neutrophil homeostasis. Here, we focused our attention on generalized pustular psoriasis (GPP), a potentially life-threatening disorder presenting with cutaneous and systemic neutrophilia. Following the whole-exome sequencing of 19 unrelated affected individuals, we identified a subject harboring a homozygous splice-site mutation (c.2031-2A>C) in MPO. This encodes myeloperoxidase, an essential component of neutrophil azurophil granules. MPO screening in conditions phenotypically related to GPP uncovered further disease alleles in one subject with acral pustular psoriasis (c.2031-2A>C;c.2031-2A>C) and in two individuals with acute generalized exanthematous pustulosis (c.1705C>T;c.2031-2A>C and c.1552_1565del;c.1552_1565del). A subsequent analysis of UK Biobank data demonstrated that the c.2031-2A>C and c.1705C>T (p.Arg569Trp) disease alleles were also associated with increased neutrophil abundance in the general population (p = 5.1 × 10-6 and p = 3.6 × 10-5, respectively). The same applied to three further deleterious variants that had been genotyped in the cohort, with two alleles (c.995C>T [p.Ala332Val] and c.752T>C [p.Met251Thr]) yielding p values < 10-10. Finally, treatment of healthy neutrophils with an MPO inhibitor (4-Aminobenzoic acid hydrazide) increased cell viability and delayed apoptosis, highlighting a mechanism whereby MPO mutations affect granulocyte numbers. These findings identify MPO as a genetic determinant of pustular skin disease and neutrophil abundance. Given the recent interest in the development of MPO antagonists for the treatment of neurodegenerative disease, our results also suggest that the pro-inflammatory effects of these agents should be closely monitored.

RESUMO

BACKGROUND: Systemic oral phosphodiesterase type 4 (PDE-4) inhibitors have been effective in the treatment of psoriasis. Roflumilast cream contains a PDE-4 inhibitor that is being investigated for the topical treatment of psoriasis. METHODS: In this phase 2b, double-blind trial, we randomly assigned adults with plaque psoriasis in a 1:1:1 ratio to use roflumilast 0.3% cream, roflumilast 0.15% cream, or vehicle (placebo) cream once daily for 12 weeks. The primary efficacy outcome was the investigator's global assessment (IGA) of a status of clear or almost clear at week 6 (assessed on a 5-point scale of plaque thickening, scaling, and erythema; a score of 0 indicates clear, 1 almost clear, and 4 severe). Secondary outcomes included an IGA score indicating clear or almost clear plus a 2-grade improvement in the IGA score for the intertriginous area and the change in the Psoriasis Area and Severity Index (PASI) score (range, 0 to 72, with higher scores indicating worse disease). Safety was also assessed. RESULTS: Among 331 patients who underwent randomization, 109 were assigned to roflumilast 0.3% cream, 113 to roflumilast 0.15% cream, and 109 to vehicle cream. An IGA score indicating clear or almost clear at week 6 was observed in 28% of the patients in the roflumilast 0.3% group, in 23% in the roflumilast 0.15% group, and in 8% in the vehicle group (P<0.001 and P = 0.004 vs. vehicle for roflumilast 0.3% and 0.15%, respectively). Among the approximately 15% of patients overall who had baseline intertriginous psoriasis of at least mild severity, an IGA score at week 6 indicating clear or almost clear plus a 2-grade improvement in the intertriginous-area IGA score occurred in 73% of the patients in the roflumilast 0.3% group, 44% of those in the roflumilast 0.15% group, and 29% of those in the vehicle group. The mean baseline PASI scores were 7.7 in the roflumilast 0.3% group, 8.0 in the roflumilast 0.15% group, and 7.6 in the vehicle group; the mean change from baseline at week 6 was -50.0%, -49.0%, and -17.8%, respectively. Application-site reactions occurred with similar frequency in the roflumilast groups and the vehicle group. CONCLUSIONS: Roflumilast cream administered once daily to affected areas of psoriasis was superior to vehicle cream in leading to a state of clear or almost clear at 6 weeks. Longer and larger trials are needed to determine the durability and safety of roflumilast in psoriasis. (Funded by Arcutis Biotherapeutics; ARQ-151 201 ClinicalTrials.gov number, NCT03638258.).

RESUMO

With recent advancements in the understanding of vitiligo pathogenesis, Janus kinase (JAK) inhibitors have emerged as a promising new treatment modality, but their effects remain incompletely elucidated. Tofacitinib, an oral JAK 1/3 inhibitor approved for the treatment of rheumatoid arthritis, has previously been shown to induce significant re-pigmentation in vitiligo. However, as with other novel targeted therapies, cutaneous adverse effects have been observed. We report a 36-year-old woman with a history of rheumatoid arthritis, refractory to multiple pharmacotherapies, who was initiated on tofacitinib and subsequently developed progressive depigmented patches consistent with new-onset vitiligo. Although definitive causation cannot be established in this case without additional studies, it is important to note that many targeted therapies have the potential to induce paradoxical effects, that is, the occurrence or exacerbation of pathologic conditions that have been shown to respond to these medications. Paradoxical findings with other targeted therapies include the occurrence of melanoma during treatment with BRAF inhibitors, keratoacanthomas with PD-1 inhibitors, vitiligo and psoriasis with TNF-alpha inhibitors, and hidradenitis suppurativa with various biologic agents. Although JAK inhibitors hold therapeutic promise in the treatment of inflammatory skin disorders, further research is warranted to more fully comprehend their effects.

RESUMO

BACKGROUND: Psoriasis is a multifactorial chronic inflammatory skin disease characterized by erythemato-squamous lesions with a chronic relapsing course. The desease clinical activity (PASI) and the patient's quality of life (DLQI) are the main elements to assess for setting up a correct therapeutic management. OBJECTIVES: The aim of the study was to evaluate the management of the patient with moderate-severe psoriasis in therapy with biological drugs and to establish the difference in the achievement of PASI 90 and DLQI 0-1 between a group of patients treated with only biological drugs and a group of patients receiving biologic therapy in combination with a topical ointment. METHODS: We conducted a prospective, observational real-life study enrolling 60 patients with moderate to severe psoriasis and divided in two groups: Group A patients treated with biological drugs, Group B patiens treated with biological drugs in association with an ointment composed of betamethasone, salicylic acid and ammonium sulpho-ichtyolate, applied 2 times a day. PASI and DLQI were evaluated at study beginning (T0) for both study groups, after 12 weeks (T3) for sample in therapy with biological drugs and after 24 weeks (T6) for sample in co-medication therapy. RESULTS: The two-way ANOVA method was used to evaluate the standard deviations (SD): at T3 and T6 Group B obtained a significant PASI reduction and improvement of DLQI (* p value <0.05) compared to Group A. CONCLUSIONS: Our study shown that the patients treated with biologics in co-medication with topical therapy reached a significantly higher PASI and DQLI compared with those treated with only biologics. Furthermore we observed that the association with topical oinment showed more efficacy in the treatment of areas such as palm-plantar region, that is often difficult-to-treat region, even for biologic drugs.

RESUMO

Secukinumab, ixekizumab and brodalumab are monoclonal antibody therapies that inhibit interleukin (IL)-17 activity and are widely used for the treatment of psoriasis, psoriatic arthritis and ankylosing spondylitis. The promising efficacy results in dermatology and rheumatology prompted the evaluation of these drugs in Crohn's disease and ulcerative colitis, but the onset of paradoxical events (disease exacerbation after treatment with a theoretically curative drug) prevented their approval in patients with inflammatory bowel diseases (IBDs). To date, the pathophysiological mechanisms underlying these paradoxical effects are not well defined, and there are no clear guidelines for the management of patients with disease flare or new IBD onset after anti-IL-17 drug therapy. In this review, we summarise the literature on putative mechanisms, the clinical digestive effects after therapy with IL-17 inhibitors and provide guidance for the management of these paradoxical effects in clinical practice.

RESUMO

With a prevalence of up to 20%, eczematous lesions are the most common skin adverse events of tumor necrosis factor alpha inhibitors. Eczematous lesions triggered by more modern biologics such as the IL17A antagonist secukinumab have been rarely reported. Herein, a case of secukinumab-induced pompholyx in a psoriasis patient is presented.

RESUMO

Psoriasis is a T cell-mediated disease with autoimmune characteristics modulated by genetic susceptibility along with environmental triggers. Inflammatory pathways marked with excessive production of cytokines IL-12 and IL-23, drive differentiation of pathogenic T cell responses resulting in TNF and IL-17 production. These cytokines are an integral part of the TNF/IL-23/IL-17 axis, which is responsible for maintaining inflammation in psoriatic skin. Our improved understanding of the immunopathogenesis led to the development of biological drugs in the treatment of moderate-to-severe disease. Biologics have revolutionized the management of psoriasis, highlighting the central role of TNF/IL-23/IL-17 axis in the physiopathology of the disease. Still, psoriasis usually requires long-term treatment, aiming to fully remove psoriatic lesions without experiencing adverse events. In this review, we discuss the recent findings of all 27 available head-to-head trials investigating the efficacy and safety of systemic and biologic therapies in moderate-to-severe psoriasis vulgaris, as it is thought to provide more useful knowledge than placebo intervention alone. According to our evaluation, inhibitors that specifically target IL-23 or IL-17 are clinically more beneficial than inhibitors of IL-12/IL-23 and TNF. More informative results might be obtained by comparing these more efficient biological agents to each other. In addition, newer therapies for psoriasis using small-molecule drugs may represent important advances compared to well-established biologics as these are less expensive and orally administered.

RESUMO

RATIONALE: Ustekinumab is a biological agent that inhibits interleukin 12 and 23 and has been approved for the treatment of moderate and severe plaque psoriasis. There have been case reports that raise concerns about its oncogenic potential. We are the first authors to report a case of Hodgkin lymphoma in a psoriatic patient receiving ustekinumab. PATIENT CONCERNS: A 22-year-old asymptomatic female patient presented to our department to investigate an enlarged cervical lymph node. Her past history was unremarkable, except for psoriasis since age 13. Two months before presentation the decision to administer Ustekinumab was taken and the patient had already received 3 doses. DIAGNOSES: During workup a Stage IV Hodgkin lymphoma was discovered. INTERVENTIONS: Ustekinumab administration was discontinued. The patient received treatment with the ABVD regimen. OUTCOMES: The patient's disease was refractory to the above-mentioned treatment. Therefore, a more aggressive regimen (BEACOPP escalated) was administered. LESSONS: Growing postmarketing surveillance data and case reports indicate that further research is warranted in order to elucidate a potential association between Ustekinumab and malignancy.

RESUMO

Psoriasis is a chronic inflammatory skin disease affecting around 2-3 % of the population. The disease spectrum evolves from to the knees and elbows limited disease to erythrodermic psoriasis. The impact on the quality of life, the pruritus, the pain from palmo-plantar disease, arthropathic psoriasis and the comorbidities are the major complaints of the patients. The treatment relies on topical treatments with dermocorticosteroids with or without vitamin D derivatives, UVA or UVB phototherapy, conventional treatments including methotrexate, ciclosporin and acitretin, and, since around 15 years, biological treatments. The biological treatments for moderate to severe psoriasis progressed in a spectacular way with an improvement of clinical results and an amelioration of the safety profile at every step. This article discusses these developments from the TNF? antagonists, including etanercept, adalimumab and infliximab to the newly arrivals, the anti-IL17 and anti-IL23 antagonists, the anti-PDE-4 antagonists and the JAK inhibitors.
