Abstract:
Objective:To investigate the clinical features and treatment effect of children with central nervous system demyelinating diseases and seropositivity to myelin-oligodendrocyte glycoprotein (MOG) antibody.Methods:The clinical characteristics of 28 had seropositivity to MOG among 115 children with central nervous system demyelinating diseases and who were hospitalized at Department of Neurology, Children′s Hospital of Zhejiang University School of Medicine from March 2017 to February 2019 were retrospectively analyzed.Results:Twenty-eight patients were included in this study, including 10 males and 18 females, with the ratio of male/female of 1.00∶1.80, and the median age of 7 years and 9 months.The clinical manifestations were diverse, including encephalopathy symptoms such as hea-dache, vomiting, and drowsiness (13/28 cases), vision loss (7/28 cases), spinal symptoms (6/28 cases), cerebellar symptoms such as ataxia, slurred speech (4/28 cases), convulsions (2/28 cases), and cranial nerve symptoms (1/28 cases). Among 24 cases who underwent CSF detection, 10 patients (41.7%) had slightly increased white blood cells, 2 patients (8.3%) had elevated protein, 6 patients (25.0%) had positive MOG antibody, and CSF-restricted oligoclonal band was negative in all 24 patients.Twenty-five cases (89.3%) showed brain magnetic resonance imaging (MRI) abnormalities, including cerebral white matter (20/28 cases), cerebellum (10/28 cases), cerebral gray matter (9/28 cases), thalamus/basal ganglia (6/28 cases), brainstem (6/28 cases), optic nerve (5/28 cases), and corpus callosum (4/28 cases). Of the 28 cases, 13 patients had spinal cord involvement, involving cervical spinal cord in 10 cases, thoracic cord in 9 cases and lumbar spinal cord in 5 cases; besides, 8 cases of them had long segmental spinal cord lesions with ≥ 3 segments.Fourteen patients received the visual evoked potentials′ examination, and the subclinical visual impairment was found in 2 of them with unobstructed clinical performance.All patients underwent high-dose Methylprednisolone therapy.The clinical symptoms of 16 patients who were treated with Gamma globulin were relieved in the acute phase.Seven patients had recurrence during the follow-up period, with the recurrence rate of 25.0%.Relapsed patients re-treated with high-dose Methylprednisolone therapy combined with Gamma globulin, clinical symptoms could be alleviated.Conclusion:The main clinical phenotype of children with central nervous system demyelinating diseases and seropositivity to MOG is acute disseminated encephalomyelitis.The spinal cord lesions are mainly involving cervical and thoracic segments.The current treatments of this disease include glucocorticoid and Gamma globulin, which have significant effect, but the disease is easy to relapse.The re-use of glucocorticoid and Gamma globulin after relapse is still effective.
