RESUMEN
La Dermatomiositis Juvenil representa el 75-80% de las miopatías inflamatorias juveniles. Si bien, tiene baja incidencia y prevalencia, presenta importante morbilidad dada por sus manifestaciones cutáneas, musculares, pulmonares, gastrointestinales, cardiacas, entre otras. Corresponde a un desorden poligénico con múltiples factores gatillantes, que determina el desarrollo de una vasculopatía que lleva a atrofia muscular, inflamación y activación de vías del IFN-1. Actualmente su diagnóstico se basa en las guias EULAR/ACR (2017). En los últimos años, se han descubiertos distintos subtipos de la enfermedad, basados en el perfil de autoanticuerpos específicos de miositis, lo que ha permitido establecer pronóstico y estrategias terapéuticas personalizadas. El manejo farmacológico continúa basándose principalmente en el uso de corticoesteroides y DMARDs, así como también terapia biológica; en los últimos años, los inhibidores JAK han mostrado resultados promisorios, convirtiéndose en la más nueva alternativa terapéutica para el control de la enfermedad.
ABSTRACT
Juvenile Dermatomyositis represents 75-80% of juvenile inflammatory myopathies. Although it has a low incidence and prevalence, it presents significant morbidity due to its cutaneous, muscular, pulmonary, gastrointestinal and cardiac manifestations, among others. It corresponds to a polygenic disorder with multiple triggering factors, which determines the development of a vasculopathy that leads to muscle atrophy, inflammation and activation of IFN-1 pathways. Currently its diagnosis is based on the EULAR/ACR guidelines (2017). In recent years, different subtypes of the disease have been discovered, based on the profile of myositis-specific autoantibodies, which has made it possible to establish prognosis and personalized therapeutic strategies. Pharmacological management continues to be based mainly on the use of corticosteroids and DMARDs, as well as biological therapy; In recent years, JAK inhibitors have shown promising results, becoming the newest therapeutic alternative for disease control.
