Abstract
Rituximab is a chimeric murine-human monoclonal antibody that is directed against the specific B-cell CD20 antigen, which has recently been successfully used in active or refractory systemic lupus erythematosus (SLE) manifestations, such as nephritis, thrombocytopenia, and vasculitis. We report a case of a 25-year-old woman diagnosed with diffuse alveolar hemorrhage of SLE refractory to steroid pulse therapy. The patient was treated successfully with rituximab as a part of the immunosuppressive regimen.
