Summary
Autoimmune encephalitis is an autoimmune disease of the central nervous system that targets neuronal autoantigens. Anti-neuronal autoantibodies are produced in patients, with anti-NMDAR antibody being the most common.Anti-NMDAR encephalitis can be severe and life-threatening. Anti-NMDAR autoantibodies against neurons are pathogenic and are mainly produced by autoreactive B cells and plasma cells. Therefore, early elimination of these abnormal immune cells is crucial for rapid improvement of the patient's condition. This study aims to explore the efficacy and safety of B cell depletion therapy (ofatumumab) followed by plasma cell depletion therapy (daratumumab) in the treatment of severe anti-NMDAR autoimmune encephalitis.
