Methods: We describe 8 Colombian patients with severe and/or refractory TA treated with TCZ during a period of at least 9 months. Clinical, radiological, biological, and associated treatments were evaluated before, during, and after TCZ infusions. Results: The median age at evaluation was 31 years (12–43 years). All patients were female and experienced clinical and biological improvement, in addition to a corticosteroid-sparing effect from a median dose of 50 mg/d at baseline (30–60 mg/d) to 6.25 mg/d (2.5–10 mg/d) at 9 months. In 4 cases, in which imaging studies were available, an improvement was observed. %K Arteritis de Takayasu %K Tratamiento %K Ciencias socio biomédicas %K Biomedical sciences %K Medicina %K Interleukin-6 %K Reumatología %~ GOEDOC, SUB GOETTINGEN
