Infliximab therapy in established rheumatoid arthritis: An observational study

Infliximab was found to be an alternative treatment with a relatively acceptable toxicity profile, despite the fact that two patients developed pulmonary tuberculosis. After the third year of therapy, 59% of patients continued to be treated with infliximab. The concomitant use of methotrexate was associated with the continuation of infliximab therapy.
