Recomendaciones para el tratamiento de la amiloidosis AL

Abstract

Introducción: La amiloidosis por cadenas livianas de inmunoglobulinas (AL) es una enfermedad poco frecuente. El tratamiento implica un desafío, justificado en parte por el compromiso sistémico y la evidencia científica escasa. Objetivos: Elaborar recomendaciones basadas en la evidencia que permitan realizar un adecuado tratamiento de pacientes con amiloidosis AL. Métodos: Se generó un listado de preguntas con formato PICO centradas en la efectividad y seguridad del tratamiento de la amiloidosis AL. Se realizó la búsqueda en PubMed, Cochrane y Epistemonikos. Los niveles de evidencia y los grados de recomendación se basaron en el sistema GRADE. Resultados: Se generaron 11 recomendaciones. En pacientes con amiloidosis AL seleccionados, se recomienda el trasplante autólogo de células progenitoras hematopoyéticas (TCPH) poste rior a una inducción con esquemas basados en bortezomib y el acondicionamiento con melfalán, ya que podría profundizar la respuesta hematológica, de órgano, su durabilidad y mejorar la supervivencia. En pacientes no elegibles para TCPH, se recomienda el tratamiento de primera línea con esquemas basados en bortezomib, dado que es probable que logre mayor tasa de respuesta hematológica, de órgano y mejore la supervivencia. En pacientes con contraindicación o inaccesibilidad al bortezomib, se recomienda el tratamiento con agentes alquilantes y corticoides, dado que es probable que logren la respuesta hematológica, de órgano y mejoren la supervivencia. Discusión: Estas recomendaciones de tratamiento se basan en la evidencia disponible y la ex periencia del panel de expertos, en un escenario de recursos disponibles limitados, acorde a los países en vías de desarrollo.

Introduction: Immunoglobulin light chain (AL) amyloidosis is a rare disease. Treatment is chal lenging, justified in part by systemic compromise and limited scientific evidence. Objectives: Develop evidence-based recommendations that allow adequate treatment of patients with amyloidosis AL. Methods: A list of PICO format questions focused on the effectiveness and safety of amyloidosis AL treatment was generated. PubMed, Cochrane and Epistemonikos were searched. The levels of evidence and grades of recommendation were based on the GRADE system. Results: 11 recommendations were generated. In selected patients with amyloidosis AL, autologous hematopoietic stem cell transplantation (ASCT) is recommended after induction with bortezomib-based regimens and conditioning with melphalan, since it could deepen the hematological and organ response, its durability and improve survival. In patients not eligible for ASCT, first-line treatment with bortezomib-based regimens is recommended, since it is likely to achieve a higher rate of hematological and organ response and improve survival. In patients with a contraindication or inaccessibility to bortezomib, treatment with alkylating agents and corticosteroids is recommended, since they are likely to achieve haematological and organ response and improve survival. Discussion: These treatment recommendations are based on the available evidence and the experience of the panel of experts, in a scenario of limited available resources, according to developing countries.
