¿Es efectivo el ustekinumab para la artritis psoriásica que no responde a tratamiento inicial? / Is ustekinumab effective for psoriatic arthritis with insufficient response to initial treatment?

INTRODUCCIÓN: La artritis psoriásica es una artritis inflamatoria sin una clara etiología, con el tratamiento biológico como un pilar fundamental en pacientes más complejos. Existen varias alternativas para tratamiento biológico, debido a su alto costo, es importante evaluar la real efectividad de estos para un buen tratamiento. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud a nivel mundial, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos 12 revisiones sistemáticas que en conjunto incluyen tres ensayos aleatorizados. Concluimos que el ustekinumab logra una mejoría clínica en pacientes con psoriasis, y probablemente no se asocia a efectos adversos graves.

INTRODUCTION: Psoriatic arthritis is an inflammatory arthritis without a clear etiology. Biological therapy is key for its treatment, especially in more complex patients. There are several alternatives for biological treatment, but due to its high cost, it is important to evaluate their real effectiveness. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified 12 systematic reviews including three randomized trials overall. We concluded ustekinumab leads to clinical improvement in psoriatic arthritis, and probably is not associated to severe adverse effects.

Secukinumab para psoriasis en placa / Secukinumab for plaque psoriasis

INTRODUCCIÓN: Los tratamientos biológicos han aparecido como principal alternativa para el manejo de los pacientes con psoriasis en placa que no responden a tratamiento convencional, resultando necesario evaluar su real efectividad y seguridad. MÉTODOS: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos 21 revisiones sistemáticas que en conjunto incluyeron diez estudios primarios, todos correspondientes a ensayos aleatorizados. Concluimos que secukinumab logra mejoría clínica en pacientes con psoriasis en placa, aunque probablemente se asocia a efectos adversos graves.

INTRODUCTION: Biological treatments have appeared as the main alternative for the management of patients with plaque psoriasis that do not respond to conventional treatment. So, evaluating its actual efficacy and safety is needed. METHODS: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified 21 systematic reviews including ten studies overall, of which all were randomized trials. We concluded secukinumab achieves clinical improvement in patients with plaque psoriasis, although it is probably associated with serious adverse effects.

Efectividad de la terapia fotodinámica con ácido 5-aminolevulínico en el tratamiento de la hidrosadenitis supurativa. Serie de 5 casos / Effectiveness of 5-Aminolevulinic Acid Photodynamic Therapy in the Treatment of Hidradenitis Suppurativa: A Report of 5 Cases

La hidrosadenitis supurativa (HAS) se ha definido como una enfermedad inflamatoria crónica, recurrente y debilitante, que compromete todo el folículo piloso. Varias alternativas terapéuticas, incluida la terapia fotodinámica, han sido utilizadas, con resultados variables y altas tasas de recurrencia. El presente trabajo muestra la evaluación de severidad, calidad de vida y seguridad de una serie prospectiva de 5 pacientes con HAS moderada o severa, sometidos a terapia fotodinámica, utilizando ácido 5-aminolevulínico (ALA) y luz 635 nm. Se evaluó la efectividad del tratamiento con el score de severidad de Sartorious, índice de calidad de vida (DLQI) y una escala visual analógica (EVA) para dolor y actividad de la enfermedad. Los pacientes mostraron una mejoría significativa en las 3 variables estudiadas, con efectos visibles que se mantenían a las 8 semanas, sugiriendo que esta terapia podría ser efectiva en HAS refractaria a terapias convencionales, disminuyendo la gravedad y mejorando la calidad de vida de los pacientes

Hidradenitis suppurativa has been described as a chronic, recurrent, and disabling inflammatory disease involving the entire hair follicle. Several treatments, including photodynamic therapy, have been used, but the results have been inconsistent and recurrence is high. In this prospective study, we evaluated disease severity, quality of life, and treatment tolerance in 5 patients with moderate to severe hidradenitis suppurativa treated with photodynamic therapy using 5-aminolevulinic acid and a 635-nm light source. Treatment effectiveness was evaluated using the Sartorius severity score, the Dermatology Life Quality Index, and a visual analog scale for pain and disease activity. Significant improvements were observed with all 3 instruments and the effects remained visible at 8 weeks. Our results suggest that photodynamic therapy with 5-aminolevulinic acid and a light wavelength of 635 nm could reduce disease severity and improve quality of life in patients with difficult-to-treat hidradenitis suppurativa
