[Targeted therapies for connective tissue diseases and vasculitis].

Targeted therapies are nowadays commonly used in connective tissue diseases and vasculitis. Experts recommend the use of belimumab and rituximab in refractory and/or severe cases of lupus. Rituximab can be also considered in difficult to treat cases of Sjögren's disease or myositis. Nintedanib seems a very promising weapon in the management of systemic sclerosis-associated pulmonary fibrosis. Regarding vasculitis, rituximab has become the preferred treatment for granulomatosis with polyangiitis and microscopic polyangiitis. Finally, tocilizumab is recommended as a steroid-sparing agent in giant cell arteritis. Further clinical trials are warranted to study the efficacy of other targeted therapies in connective tissue diseases and vasculitis.
