ABSTRACT

Los inhibidores de checkpoint (ICP) son anticuerpos usados en inmunoterapia contra el cáncer. Uno de sus blancos de acción es el receptor de muerte celular programada-1 (PD-1), el cual es importante para mantener la tolerancia inmunitaria. Sin embargo, este mecanismo se asocia a riesgo de eventos adversos relacionados a la inmunidad que pueden afectar a múltiples órganos incluyendo el sistema endocrino. Se describe el caso inhabitual de un paciente que a los 18 meses de terapia con ICP debutó con cetoacidosis diabética (CAD).


Immune checkpoint inhibitors consist in antibodies used in immunotherapy against cancer. One of their targets is the programmed cell death-1 (PD-1) receptor, which is important in maintaining self-tolerance. However, this mechanism is associated with a risk for immune-related adverse events potentially affecting multiple organs, including the endocrine system. We describe the unusual case of a patient who, after 18 months of treatment with an immune checkpoint inhibitor, debuted with diabetic ketoacidosis

ABSTRACT

Introducción: Los nuevos antineoplásicos son medicamentos innovadores en el tratamiento del cáncer. Actualmente hay poca información sobre la seguridad y efectos adversos de estos medicamentos a nivel retiniano. Es importante conocer estos efectos para prevenir pérdida de visión en pacientes oncológicos. Objetivo: Definir cuáles son los hallazgos de toxicidad retiniana en los usuarios de nuevos antineoplásicos. Diseño del estudio: Revisión de la literatura. Métodos: Se realizó una búsqueda de literatura en PubMed, Embase, Cochrane, Scielo y literatura gris con términos MeSH: "toxicity" AND "retina" AND "drugs" AND/OR "MEK inhibitors", "BRAF inhibitors", "checkpoint inhibitors". Se seleccionaron 16 artículos para análisis y extracción de datos. Resultados: Existen múltiples efectos adversos reportados en la literatura, los más comunes son desprendimiento de retina exudativo y seroso asociado a la presencia de líquido subretiniano, oclusión de vena central de retina y alteraciones vasculares. La patología más estudiada ha sido melanoma metastásico y la terapia que más presenta efectos adversos ha sido la combinada MEK-BRAF.


Background: The new antineoplastics are innovative drugs in the treatment of cancer. There is currently little information on the safety and adverse effects of these medications at the retinal level. It is important to know these effects to prevent vision loss in cancer patients. Objective: To define the characteristics of retinal toxicity in patients who use new antineoplastic drugs. Study design: Literature review. Methods: A literature search was carried out in PubMed, Embase, Cochrane, Scielo and gray literature with MeSH terms: "toxicity" AND "retina" AND "drugs" AND/OR "MEK inhibitors", "BRAF inhibitors", "checkpoint inhibitors". 16 articles were selected for analysis and data extraction. Results: There are multiple adverse effects reported in the literature, the most common are exudative and serous retinal detachment associated with the presence of subretinal fluid, central retinal vein occlusion and vascular alterations. The most studied pathology has been metastatic melanoma and the therapy with the most adverse effects has been the combined MEK-BRAF
