Effectively used as a single agent or combined with a chemotherapy regimen to treat lymphoma, RTX is a significant step forward in the arsenal treatment of idiopathic thrombocytopenic purpura, systemic lupus erythematous, rheumatoid arthritis, and autoimmune hemolytic anemia. Side effects of RTX are commonly seen during the first infusion in up to 50% of patients and include fever, chills, and rigors. These side effects are generally transient and related to the tumor burden, probably due to a greater degree of complement activation and proinflammatory cytokine release. Severe lung toxicity like cryptogenic organizing pneumonia, pneumonitis, and interstitial lung diseases are infrequent, with most of the knowledge coming from case reports.展开更多
