[Guidelines on atopic dermatitis for Mexico (GUIDAMEX): using the ADAPTE methodology]. / Guía de dermatitis atópica para México (GUIDAMEX): lineamientos usando metodología ADAPTE.

With the advancement of knowledge in relation to the physiopathogenesis of atopic dermatitis (AD), several new therapeutic forms have been developed. There are also new guidelines for self-care. On the other hand, there is still an underdiagnosis of AD in Mexico. Thus, the need was seen to develop a national guide, with a broad base among the different medical groups that care for patients with AD. The Atopic Dermatitis Guidelines for Mexico (GUIDAMEX) was developed with the ADAPTE methodology, with the endorsement and participation of ten national medical societies, from physicians in Primary Healthcare to allergists and dermatologists. Throughout the manuscript, key clinical questions are answered that lead to recommendations and suggestions for the diagnosis of AD (including differential diagnosis with immunodeficiency syndromes), the recognition of comorbidities and complications, non-pharmacological treatment including therapeutic education, treatment of flares and maintenance therapy. The latter encompasses general measures to avoid triggering factors, first-line treatment focussed on repair of the skin barrier, second-line treatment (topical proactive therapy), and third-line phototherapy or systemic treatment, including dupilumab and JAK inhibitors.

Con el avance de los conocimientos en relación con la fisiopatogenia de la dermatitis atópica (DA) se han desarrollado varias formas terapéuticas nuevas. Asimismo, existen nuevos lineamientos para el autocuidado. Por otro lado, aún existe un subdiagnóstico de la DA en México. Así, se vio la necesidad de desarrollar una guía nacional, con base amplia entre las diferentes agrupaciones médicos que atienden pacientes con DA. Se desarrolló la Guía de DA para México (GUIDAMEX) con la metodología ADAPTE, con el aval y la participación de diez sociedades médicas nacionales, desde médicos del primer contacto hasta alergólogos y dermatólogos. A lo largo del escrito se contestan preguntas clínicas clave que llevan a recomendaciones y sugerencias para el diagnóstico de la DA (incluyendo diagnóstico diferencial con síndromes de inmunodeficiencia), el reconocer de las comorbilidades y complicaciones, las medidas generales (tratamiento no farmacológico) incluyendo la educación terapéutica, el tratamiento de los brotes y el tratamiento de mantenimiento. Este último abarca las medidas generales de evitar agravantes, el tratamiento de primera línea reparador de la barrera cutánea, de segunda línea (manejo proactivo tópico), hasta la fototerapia y el tratamiento sistémico de la tercera línea, incluyendo dupilumab y los inhibidores de la cinasa de Jano.

Recomendaciones del Colegio Mexicano de Reumatología para el manejo de la artritis psoriásica / Recommendations of the Mexican College of Rheumatology for the management of psoriatic arthritis

La artritis psoriásica (APs) es una enfermedad inflamatoria sistémica crónica que afecta a la piel, las estructuras musculoesqueléticas y otros órganos y sistemas, comprometiendo la funcionalidad, la calidad de vida y reduciendo la expectativa de vida de los pacientes. Es una enfermedad compleja que requiere atención y manejo especializado y oportuno. Las alternativas para el tratamiento de las manifestaciones de la APs se han incrementado y, adicionalmente, el efecto de los distintos agentes sobre manifestaciones específicas ha sido aclarado en estudios recientes, por lo tanto, es conveniente incorporar la evidencia disponible para construir una estrategia en el tratamiento de estos pacientes. El Colegio Mexicano de Reumatología seleccionó una comisión para evaluar estas distintas alternativas y generar recomendaciones. Métodos: El grupo de estudio incluyó a 16 reumatólogos y tres dermatólogos certificados, que fueron seleccionados de diferentes instituciones de salud y regiones del país. Se conformó un comité ejecutivo que coordinó las reuniones y un comité de expertos que seleccionó los criterios de búsqueda en la literatura, elaboró las preguntas de investigación, calificó la calidad de la evidencia y generó las recomendaciones en los distintos dominios de la enfermedad con base en la metodología GRADE. Resultados: Se generaron 24 recomendaciones actualizadas para el tratamiento de pacientes con APs. Las recomendaciones establecen el papel de los medicamentos disponibles actualmente en nuestro país. Se enfatiza la importancia del control adecuado de la enfermedad, individualizando el perfil de involucramiento de cada paciente en cada uno de los seis dominios potencialmente afectados por la enfermedad. Además, se establece la secuencia en la elección de los tratamientos disponibles para cada dominio, basada en su eficacia, perfil de seguridad y accesibilidad.(AU)

Psoriatic arthritis is a chronic systemic inflammatory disease that affects the skin, musculoskeletal structures and other organs and systems compromising functionality, quality of life and reducing the life expectancy of patients. It is a complex disease that requires specialist and timely care and management. The alternatives for treating the manifestations of psoriatic arthritis have increased and the effect of the different agents on specific manifestations has been clarified in recent studies. Therefore, we should incorporate the available evidence to build a strategy for the treatment of these patients. The Mexican College of Rheumatology selected a committee to evaluate these different alternatives and make recommendations. Methods: The study group included 16 rheumatologists and 3 certified dermatologists, selected from different health institutions and regions of the country. An executive committee was formed to coordinate the meetings and a committee of experts selected the literature search criteria, prepared the research questions, rated the quality of the evidence, and produced the recommendations in the different disease domains based on the GRADE methodology. Results: 24 updated recommendations were generated for the treatment of patients with psoriatic arthritis. The recommendations establish the role of the drugs currently available in our country. The importance of adequate disease control is emphasized, individualizing the level of involvement of each patient in each of the six domains potentially affected by the disease. In addition, the sequence in the choice of treatments available for each domain is established, based on their efficacy, safety profile and accessibility. Conclusions: With this consensus document, it will be possible to improve the care of patients with psoriatic arthritis. The recommendations were generated based on the best available information and in consideration of the Mexican health system.(AU)

[Mexican treatment goals for plaque psoriasis]. / Metas mexicanas de tratamiento de psoriasis en placas.

Psoriasis is a chronic inflammatory disease with a worldwide prevalence between 6 and 39% in moderate to severe forms. In European countries like Germany and England was identified that only one third of patients with moderate to severe forms will receive systemic management, this fact motivated to integrate into Europe an international consensus on treatment goals with the aim of providing support to the dermatologist by algorithms that serve as a therapeutic guide that allows you to gain control short and long term effects of this disease. The European group met to develop the definitions of severity of psoriasis, treatment goals for moderate to severe disease, and optimization options and / or therapeutic transition than a paper published in 2011 was obtained. In Mexico a working group of experts on biological therapy (GTEB), made up of 10 members and an extended group of 150 dermatologists' voters in the country for the purpose of issuing Mexico's position on the proposals of the European group was formed. In this document the findings of the Working Group of Experts on Biological Therapy in Mexico are listed.

La psoriasis es una enfermedad crónica inflamatoria, con una prevalencia mundial entre 6 y 39% en las formas moderadas a severas. En países europeos como Alemania e Inglaterra se identificó que solo la tercera parte de los pacientes que padecen formas moderadas a severas reciben manejo sistémico; este hecho motivó la integración en Europa de un consenso internacional sobre metas de tratamiento con el objetivo de brindar apoyo al dermatólogo con algoritmos que sirvan como guía terapéutica para lograr el control a corto y largo plazo de esta enfermedad. El grupo europeo se reunió para elaborar las definiciones de severidad de la psoriasis, las metas de tratamiento en la enfermedad moderada a severa, entre otros temas, de lo que se obtuvo un documento publicado en el 2011. En México se conformó un grupo de trabajo de expertos en terapia biológica (GTEB), formado por 10 integrantes y un grupo extendido de 150 dermatólogos votantes del país, con la finalidad de emitir la posición de México sobre las propuestas del grupo europeo. En el presente documento se enumeran las conclusiones del grupo de trabajo de expertos en terapia biológica en México.

Efficacy of Tofacitinib for the Treatment of Moderate-to-Severe Chronic Plaque Psoriasis in Patient Subgroups from Two Randomised Phase 3 Trials.

BACKGROUND: Tofacitinib is a Janus kinase inhibitor being investigated for the treatment of moderate-to-severe plaque psoriasis. We report efficacy of tofacitinib in patient subgroups based on pooled data from two Phase 3 trials (NCT01276639, NCT01309737).
OBJECTIVES: To assess consistency of treatment effects of tofacitinib versus placebo in subgroups defined by baseline characteristics, and to ascertain whether baseline characteristics are of value in optimizing tofacitinib use.
METHODS: Pooled data from the two trials were used to evaluate ≥75% reduction in PASI from baseline (PASI75 response) in subgroups defined by age, age at psoriasis onset, gender, race, geographical region, weight, body mass index, diabetes, metabolic syndrome, tobacco/alcohol use, psoriatic arthritis, disease activity, and prior therapy.
RESULTS: Week 16 PASI75 response rates (N=1843) were 43%, 59% and 9% with tofacitinib 5 and 10mg twice daily (BID) and placebo, respectively (each P<0.0001 versus placebo). Tofacitinib 5 and 10mg BID were effective regardless of baseline characteristics. Across subgroups, tofacitinib generally produced greater response rates with the 10 versus 5mg BID dosage. Lower absolute response rates were seen in heavier patients and patients with prior biologic experience.
CONCLUSIONS: Both tofacitinib dosages demonstrated consistent efficacy versus placebo across subgroups. Lower response rates were seen in heavier patients and those with prior biologic experience. Tofacitinib 10mg BID resulted in a substantial proportion of responders regardless of baseline characteristics.

[Mexican guidelines on the diagnosis and treatment of urticaria]. / Guía Mexicana para el Diagnóstico y el Tratamiento de la Urticaria.

BACKGROUND: Urticaria is a disease that a fifth of the population shallsuffer once in a lifetime. Recent clinical guidelines have proposed some fundamental changes in the diagnosis and treatment of urticaria, making the development of a national, multidisciplinary guideline, with wide acceptability among different professional groups -both specialists and primary health care workers-, necessary in Mexico. MATERIAL AND METHOD: Internationally recognized tools for guidelinedevelopment were used. An interdisciplinary group of clinical experts (some of them knowledgeable in methodology of guideline development) determined the objectives and scope of the Evidence Based Clinical Practice Guideline with SCOPE. It was decided to adapt and transculturize international guidelines on the diagnosis and treatment of urticaria. With AGREE-II three high-quality guidelines (Zuberbier 2014, Sánchez-Borges 2012, Powell 2007) were selected to function as basic guidelines (BG). A set of Clinical Questions was formulated that lead to recommendations/suggestions, based on these BG, taking into account the cultural and economic background of Mexico, according to GRADE recommendation development. RESULTS: By a formal process of discussion and voting during several working-sessions, experts and first level healthcare physicians determined the wording of the final guideline, taking particularly care of developing a document, adjusted to the reality, values and preferences of the Mexican patients. The use of oral second generation, non-sedating antihistamines as first line treatment is emphasized. CONCLUSION: This document is an Evidence Based Clinical Practice Guideline for the diagnosis and treatment of acute and chronic urticaria, based on three, high quality, international guidelines. It was developed by a multidisciplinary group. Tables and algorithms make the guideline user-friendly for both, first line health care physicians and specialists.

Antecedentes: la urticaria es una enfermedad que padece una quinta parte de la población en algún momento de su vida. Las guías internacionales recientes han propuesto unos cambios de fondo en su diagnóstico y tratamiento, por lo que había la necesidad de crear una guía nacional y multidisciplinaria, con base amplia en los gremios de especialistas y médicos de primer contacto en México. Material y método: un grupo interdisciplinario de expertos clínicos y algunos expertos en metodología determinó los objetivos y alcances de la Guía de Práctica Clínica Basada en Evidencia con el instrumento SCOPE. Se decidió llevar a cabo la adaptación y transculturización de guías internacionales para el diagnóstico y tratamiento de urticaria. Con el instrumento AGREE-II se seleccionaron las tres guías de alta calidad, como guías base (Zuberbier 2014, Sánchez-Borges 2012, Powell 2007) para formular y contestar la preguntas clínicas clave, en el contexto cultural y económico mexicano, según el método de desarrollo de recomendaciones GRADE. Resultados: mediante un proceso formal de discusión y votación durante varias juntas de expertos, se terminó la redacción de la forma final de la guía, con especial cuidado de lograr un ajuste a las realidades, valores y preferencias de los pacientes de México. Se hace hincapié en la administración de antihistamínicos vía oral de segunda generación, como tratamiento de primera elección. Conclusión: este documento es una Guía de Práctica Clínica Basada en Evidencia para el diagnóstico y tratamiento de urticaria aguda y crónica, basada en tres guías internacionales de alta calidad. Se desarrolló por un grupo multidisciplinario. Los cuadros y algoritmos hacen a la guía amigable para su uso por médicos de primer contacto y por especialistas.

[Wiskott Aldrich syndrome associated to vasculitis: a therapeutic challenge]. / Síndrome de Wiskott Aldrich asociado con vasculitis: un desafÌo terapéutico.

Wiskott Aldrich syndrome (WAS) is an X-linked primary immunodeficiency, associated with WASP gene mutation that causes severe immunological abnormalities and alterations in platelet function. A seven year old male patient with WASP, began with acute abdominal pain, fever and knee swelling. The diagnosis of septic arthritis was made, and he was treated with broad-spectrum antibiotics and human gammaglobulin. During treatment he presented digestive tract bleeding with hypovolemic shock; after 72 hours palpable purpura in upper and lower extremities appeared. Then Henoch-Schönlein purpura with abdominal vasculitis was suspected, and later confirmed by histopathology. Methylprednisolone pulses were initiated, showing improvement within 24 hours. The patient had a severe inflammatory reaction, caused by a serious infectious disease, but the clinical evolution suggested an autoimmune disease such as Henoch-Schönlein purpura. Up to 20% of patients with WAS have autoimmune manifestations of vasculitis. An early diagnosis of autoimmunity in WAS is important for a favorable clinical outcome.

Mutación en el gen EDA1, Ala349Thr en paciente con displasia ectodérmica hipohidrótica ligada a X / Mutation in the ED1, Ala349Thr in a patient with X-linked hypohidrotic ectodermal dysplasia

Hypohidrotic ectodermal dysplasia (HED) is a very rare disease characterized by the absence of eccrine glands, dry skin, scanty hair, and dental abnormalities. It is caused by mutations within the ED1 gene, which encodes a protein, ectodysplasin-A (EDA). Clinical characteristic are frontal bossing, saddle nose, pointed chin, a prominent supraorbital ridge with periorbital hyperpigmenta-tion, and anodontia. Those affected show great intolerance to heat. We report the first Mexican 2-year-old boy with an Ala349Thr missense mutation from Tamaulipas, México.
