Immunotherapy, Cancer and Rheumatological Diseases: A Review of the Literature and a Series of Cases in a University Hospital. / Inmunoterapia, cáncer y enfermedades reumatológicas: revisión de la literatura y serie de casos en un hospital universitario.

The appearance in the field of oncology of therapeutic molecules in the form of monoclonal antibodies, whose objective is to stimulate the patient's own immune system to be responsible for destroying cancer cells, has revolutionized the treatment of many cancers in recent years. This type of therapy, called immunotherapy, is also characterized by presenting side effects in the form of autoimmune diseases that we are still beginning to understand. From the point of view of the immune-mediated rheumatological side effects, we can find musculoskeletal manifestations, mechanical, inflammatory or systemic autoimmune diseases. The therapeutic approach to these side effects remains uncertain due to the absence of clinical trials and validated recommendations. The multidisciplinary management is crucial to successfully treat such cases. In the following manuscript, we will describe our case reports of rheumatologic immune-related adverse events in a university hospital.

Rituximab therapy in necrotizing autoimmune myopathy associated with anti-SRP antibody: A clinical case review. / Tratamiento con rituximab para las miopatías necrosantes autoinmunes asociadas al anti-SRP: caso clínico y revisión de la evidencia.

Necrotizing autoimmune myopathy (NAM) is a rare and emerging entity of idiopathic inflammatory myopathy (IIM). They have been associated with connective tissue disorders, viral infections, malignancy, anti-signal recognition particle (SRP) and anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase protein (with or without the use of statins). Anti-SRP associated NAM has different clinical and histological characteristics that differentiate them from other IIM, resulting in a poor prognosis. Very few cases treated with rituximab have been published, with varying clinical response. Here we describe a case of anti-SRP associated NAM refractory to conventional immunosuppressants and its successful long-term management with the combination of rituximab, corticosteroids and methotrexate.

Las miopatías necrosantes autoinmunes (NAM) son unas entidades raras y emergentes de las miopatías inflamatorias idiopáticas (MII). Su presencia se ha asociado a conectivopatías, infecciones virales, neoplasias, anticuerpos frente a la partícula de reconocimiento de la señal (anti-SRP) y a anticuerpos frente a la proteína 3-hidroxi-3-metilglutaril-coenzima A reductasa (HMG-CR) (asociada al empleo o no de estatinas). Las NAM asociadas al anti-SRP presentan unas características clínicas y anatomopatológicas que las diferencian del resto de las MII, resultando en un peor pronóstico. Hasta el momento han sido muy pocos los casos publicados tratados con rituximab y con diferente respuesta clínica. Presentamos el caso de una mujer de 30 años con NAM asociada al anti-SRP refractaria a tratamiento convencional inmunosupresor y que ha sido controlada a largo plazo con la combinación de rituximab, metotrexato y corticoides

Inmunoterapia, cáncer y enfermedades reumatológicas: revisión de la literatura y serie de casos en un hospital universitario / Immunotherapy, cancer and rheumatological diseases: a review of the literature and a series of cases in a university hospital

La aparición en el campo de la oncología de moléculas terapéuticas en forma de anticuerpos monoclonales, cuyo objetivo consiste en estimular el propio sistema inmune del paciente para que sea este el encargado de destruir las células cancerígenas, ha revolucionado el tratamiento de diversos cánceres en los últimos años. Este tipo de terapia, denominada inmunoterapia, se caracteriza además por presentar efectos secundarios en forma de enfermedades autoinmunes que todavía estamos empezando a conocer. Desde el punto de vista de los efectos secundarios inmunomediados reumatológicos, podemos encontrar manifestaciones musculoesqueléticas mecánicas, inflamatorias o enfermedad autoinmune sistémica. El manejo terapéutico de estos efectos secundarios se mantiene variable debido a la ausencia de ensayos clínicos y de recomendaciones validadas, siendo el manejo multidisciplinar fundamental para tratar con éxito dichos casos. En este artículo presentamos nuestra serie de casos clínicos de pacientes en tratamiento con inmunoterapia y efectos secundarios inmunomediados reumatológicos en un hospital universitario
