ABSTRACT

BACKGROUND: Pemphigus (Pm) is a chronic and recalcitrant autoimmune disease that affects the skin and mucous membranes. The first line of treatment are systemic corticosteroids; however, there are patients who are refractory to them, as well as to other immunosuppressants. Rituximab has been used as a successful alternative since 2000 with good results but without information on its behavior in the Mexican population. OBJECTIVE: To assess the clinical response to treatment with rituximab in Mexican patients with pemphigus. METHODS: This was a cross-sectional, retrospective study in a tertiary hospital, which included patients with moderate-severe pemphigus who had been treated with rituximab from 2007 to 2020. RESULTS: Six medical records of patients diagnosed with pemphigus were obtained; four of them with Pm vulgaris, and two of them with pemphigus foliaceus; all patients had received systemic immunosuppressive therapy prior to rituximab. All six patients went into remission of the disease in an average of 12.5 weeks. CONCLUSION: The use of rituximab for the treatment of patients with moderate-severe Pm who were refractory to immunosuppressive therapy proved to be very useful, and control of the disease was achieved in the medium term, without severe or idiosyncratic adverse effects in the analyzed Mexican population.


Antecedentes: El pénfigo es una enfermedad autoinmune crónica y recalcitrante que afecta piel y mucosas. El tratamiento de primera línea son los corticosteroides sistémicos, aunque hay pacientes refractarios a estos y a otros inmunosupresores. Como alternativa, desde el año 2000 se ha utilizado el rituximab con buenos resultados, pero sin información de su comportamiento en población mexicana. Objetivo: Evaluar la respuesta clínica al tratamiento con rituximab en pacientes mexicanos con pénfigo. Métodos: Se trató de un estudio transversal, retrospectivo en un hospital de tercer nivel, en el que se incluyeron pacientes con pénfigo moderado-severo tratados con rituximab entre 2007 y 2020. Resultados: Se obtuvieron seis expedientes de pacientes con diagnóstico de pénfigo, cuatro presentaron la variedad vulgar y dos, la variedad foliácea; todos recibieron tratamiento sistémico inmunosupresor previo al rituximab. Los seis pacientes tuvieron remisión de la enfermedad en un promedio de 12.5 semanas. Conclusión: El rituximab para el tratamiento de pacientes con pénfigo moderado-severo refractario a tratamiento inmunosupresor demostró ser de gran utilidad y logró un control de la enfermedad a mediano plazo, sin efectos adversos severos ni idiosincráticos en la población mexicana estudiada.

ABSTRACT

In recent years, the introduction of a series of biological drugs for the treatment of psoriasis has considerably increased the therapeutic armamentarium of doctors, and thus a strongly positive impact on the control of this condition has been achieved. With the purpose to provide the best recommendations for the use of these biological agents in patients with psoriasis, the Mexican group of psoriasis experts, PSOMEX, has developed recommendations in order to improve the understanding and therapeutic positioning of this type of medications.

ABSTRACT

The development and marketing of biosimilars opens a new scenario in the treatment of many pathologies, including psoriasis. This article reflects the position of the Mexican Academy of Dermatology (AMD) on the use of biosimilar medicines for the treatment of psoriasis in Mexico. In summary, the AMD estates that there is sufficient evidence to accept comparability of pharmacokinetics and pharmacodynamics of some biosimilar medicines to adalimumab, infliximab and etanercept; this evidence does not sufficiently support interchangeability or indication extrapolation. It is essential to establish a close pharmacovigilance not only to guarantee compliance with the Cofepris rules in Mexico, but also to facilitate the effective monitoring of the adverse effects of biosimilar medicines. Although the goal of biotechnological drugs is to achieve substantial savings for patients and public institutions, no economic criteria should prevail over rigorous scientific criteria that guarantee maximum therapeutic efficacy and optimum safety for patients.


El desarrollo y comercialización de biocomparables abre un nuevo escenario en el tratamiento de muchas patologías, entre ellas la psoriasis. El presente artículo recoge la postura de la Academia Mexicana de Dermatología (AMD) respecto al uso de medicamentos biocomparables para el tratamiento de la psoriasis en México. En resumen, la AMD establece que existe suficiente evidencia para aceptar la comparabilidad farmacocinética y farmacodinámica entre algunos medicamentos biocomparables al adalimumab, el infliximab y el etanercept; esta evidencia no sustenta suficientemente su intercambiabilidad ni la extrapolación de indicaciones; es fundamental establecer una farmacovigilancia estrecha no solo para garantizar el cumplimiento de las reglas de la Comisión Federal para la Protección contra Riesgos Sanitarios en México, sino para facilitar un seguimiento efectivo de los efectos adversos de los medicamentos biocomparables. Si bien la meta de los medicamentos biotecnológicos es lograr un ahorro sustancial para los pacientes y las instituciones públicas, los criterios económicos no deben anteponerse a criterios científicos rigurosos que garanticen la máxima eficacia terapéutica y la óptima seguridad para los pacientes.

ABSTRACT

BACKGROUND: In Mexico, the economic burden of medical care for patients with atopic dermatitis is unknown. OBJECTIVE: To determine the annual direct medical costs of the treatment for patients with moderate to severe atopic dermatitis who receive medical attention at "Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado" (Institute for Social Security and Social Services for State Workers, better known as ISSSTE), as well as the main variables associated with it. METHODS: A multicenter, retrospective cohort study. Clinical records of patients with moderate to severe atopic dermatitis were reviewed and a multivariate analysis was designed by using a generalized linear model. RESULTS: 65 patients were included; 41 of them (63.07 %) had moderate atopic dermatitis, and 24 (36.92 %) had severe AD; 39 (60 %) of them were female patients. In groups with severe atopic dermatitis, statistically significant differences were observed in matters of the duration of the evolution of the disease, comorbidities, intense pruritus, and depression. The average annual cost of medical care for patients with moderate atopic dermatitis was 1527 ± 623 USD, and for patients with severe atopic dermatitis the cost was 9487 ± 8990 USD. Significant differences were observed in dermatology consultations, referrals, laboratory and diagnostic studies, and the number of drugs prescribed by physicians. With the multivariate analysis, it was identified that the highest cost was presented by severe patients (p = 0.0001) who were younger and had comorbidities, along with diagnosis of depression. CONCLUSIONS: The severity of atopic dermatitis, the age average, the presence of comorbidities, and the diagnosis of depression are the variables with the highest association and impact on the direct cost of medical care.


Antecedentes: En México se desconoce el impacto económico de la atención médica de los pacientes con dermatitis atópica. Objetivo: Determinar los costos médicos directos anuales del tratamiento de pacientes con dermatitis atópica moderada y grave que se atienden en el Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado, y las principales variables asociadas. Métodos: Estudio multicéntrico de cohorte retrospectiva. Se revisaron los expedientes clínicos de pacientes con dermatitis atópica clasificada como moderada o grave y se diseñó un modelo de análisis multivariado mediante un modelo lineal generalizado. Resultados: Se incluyeron 65 pacientes, 41 (63.07 %) tuvieron dermatitis atópica moderada y 24 (36.92 %), grave; 39 (60 %) fueron del sexo femenino. En los grupos con dermatitis atópica grave se observaron diferencias estadísticamente significativas en años de evolución de la enfermedad, comorbilidades, prurito intenso y depresión. El costo promedio anual de la atención médica para dermatitis atópica moderada fue de 1527 ± 623 USD y para dermatitis atópica grave, de 9487± 8990 USD. Se obtuvieron diferencias estadísticamente significativas en consultas de dermatología, interconsultas, estudios de laboratorio y gabinete y número de medicamentos prescritos. Con el análisis multivariado se identificó que el costo mayor lo presentaban los pacientes graves (p = 0.0001), más jóvenes, con comorbilidades y diagnóstico de depresión. Conclusiones: La gravedad de la dermatitis atópica, la edad, presentar comorbilidades y contar con el diagnóstico de depresión son las variables con mayor asociación e impacto en el costo directo de la atención médica.

ABSTRACT

Resumen ANTECEDENTES: La hidradenitis supurativa es una enfermedad inflamatoria, crónica y recurrente con gran repercusión en la calidad de vida de los pacientes, específicamente en los aspectos psicológicos y sexuales, así como también en la productividad laboral. OBJETIVO: Generar un documento de consenso sobre el manejo clínico de los pacientes con hidradenitis supurativa en México que sirva para homologar el diagnóstico y tratamiento de estos pacientes. MÉTODO: Se convocó a un grupo multidisciplinario (dermatólogos, ginecólogos, cirujanos, infectólogos, proctólogos) para analizar la evidencia en el tratamiento integral de la hidradenitis supurativa (calidad de vida, clinimetría, diagnóstico y tratamiento), localizada mediante una revisión sistemática de la bibliografía. El grupo discutió sobre los temas y se generaron las recomendaciones por acuerdo unánime de los participantes. RESULTADOS: Con frecuencia los pacientes con hidradenitis supurativa pueden tardar mucho tiempo en obtener el diagnóstico y manejo correctos, principalmente debido a la falta de evidencia sobre la enfermedad, así como a la falta de criterios para referir al paciente con un especialista. Se emitieron 22 recomendaciones para el tratamiento de pacientes con hidradenitis supurativa, que comprenden el diagnóstico, estadificación y clinimetría, así como el manejo clínico en el primer, segundo y tercer nivel de atención. CONCLUSIONES: Se emitieron las recomendaciones con base en la mejor evidencia disponible, así como la experiencia del grupo multidisciplinario de expertos en el tratamiento de hidradenitis supurativa.


Abstract BACKGROUND: Hidradenitis suppurativa is an inflammatory, chronic and recurrent disease with a high impact on patients quality of life, specifically in psychological and sexual aspects, as well as in labor productivity. OBJECTIVE: To generate a consensus document on the clinical management of patients with hidradenitis suppurativa in Mexico, that serves to standardize the diagnosis and treatment of these patients. METHOD: A multidisciplinary group was convened (dermatologists, gynecologists, surgeons, infectologists, proctologists) to analyze the evidence on the integral treatment of hidradenitis suppurativa (quality of life, clinimetry, diagnosis and treatment), located through a systematic review of the literature. The group discussed the issues and the recommendations were generated by unanimous agreement of the participants. RESULTS: Frequently, patients with hidradenitis suppurativa can take a long time to obtain the correct diagnosis and management, mainly due to the lack of evidence about the disease, as well as the lack of criteria to refer the patient to a specialist. Twenty-two recommendations were issued for the treatment of patients with hidradenitis suppurativa, which include diagnosis, staging and clinimetry, as well as clinical management in the first, second and third levels of care. CONCLUSIONS: The recommendations were issued based on the best available evidence, as well as the experience of the multidisciplinary group of experts in the treatment of hidradenitis suppurativa.

ABSTRACT

Calcific uremic arteriolopathy (CUA) or calciphylaxis is a syndrome characterized by calcification of vessels located in the dermis and adipose tissue. It commonly occurs in patients with diabetes mellitus, hypertension, and end-stage renal disease. Clinical presentation generally begins with severe pain, followed by the presence of liveloid or purpuric plaques. Later the formation necrotic ulcers occur. This condition is associated with a poor prognosis, with a high rate of mortality within months of the diagnosis. Penile involvement is an uncommon but severe manifestation. We present an 81-year-old man with a history of diabetes mellitus, hypertension, and end-stage renal disease with a one-month evolution of painful necrotic ulcers on his glans penis. He was diagnosed with CUA. Owing to infection complicated by sepsis; penectomy was performed. Unfortunately, the patient died of myocardial infarction during his hospitalization.

ABSTRACT

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.
