Objective: To analyze the clinical features of children with refractory N-methyl-D-aspartate (NMDA) receptor antibody encephalitis treated with tocilizumab. Methods: Demographic and clinical manifeatations, immunotherapy and prognosis data of 9 children with refractory NMDA receptor antibody encephalitis who received tocilizumab in the Department of Pediatrics Neurology, XiangYa Hospital of Central South University from August 2021 to September 2023 were collected retrospectively. Prognosis was evaluated using the modified Rankin scale at initial diagnosis, at the initiation of tocilizumab treatment, and at the last follow-up. Treatment related complications, neuroimaging, and electroencephalography data were analyzed. Results: Among the 9 children, 6 were male and 3 were female, with an onset age of 4.2 (2.8, 8.7) years. At the onset of the disease, 9 children had a modified Rankin scale score of 5. When tocilizumab treatment was initiated, 7 children had a score of 5, and 2 children had a score of 4. The interval between the onset and initiation of tocilizumab treatment was 12 (5, 27) months, and the treatment frequency was 8 (5, 13) times. The follow-up time was 2.8 (1.5, 3.7) years. At the last follow-up, the symptoms of 9 children, including movement disorder, sleep disorder, consciousness disorder, silence and autonomic dysfunction, were improved to varying degrees, and none of them had seizures. At the last follow-up, 4 cases with a modified Rankin scale score of 0, 1 case with a score of 1, 2 cases with a score of 3, 1 case with a score of 4 and 1 case with a score of 5. The modified Rankin scale at the last follow-up was significantly different from that at the start of tocilizumab ( Z =-2.56, P =0.014). All children had no serious adverse reactions during the treatment. Conclusions: After treatment with tocilizumab, the symptoms in patients with refractory NMDA receptor antibody encephalitis, including movement disorder, sleep disorder, consciousness disorder, silence and autonomic dysfunction were improved, and none of them had seizures. The modified Rankin scale were improved, and the safety was good. |
