RESUMEN

OBJECTIVES@#To study the clinical features of children with autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A).@*METHODS@#A retrospective analysis was performed on the medical data of 34 children with GFAP-A who attended the Department of Neurology, Children's Hospital of Chongqing Medical University, from January 2020 to February 2022. The medical data included clinical manifestations, cerebrospinal fluid features, imaging examination results, treatment, and prognosis.@*RESULTS@#The median age of onset was 8.4 (range 1.9-14.9) years for the 34 children with GFAP-A. The main clinical manifestations included headache (50%, 17/34), fever (47%, 16/34), visual impairment (47%, 16/34), and disturbance of consciousness (44%, 15/34). Abnormal cerebrospinal fluid results were observed in 19 children (56%, 19/34), among whom 8 children had positive autoantibody. The children with overlap syndrome had significantly higher recurrence rate and rate of use of immunosuppressant than those without overlap syndrome (P<0.05). About 77% (24/31) of the children had good response to immunotherapy, and only 1 child had poor prognosis.@*CONCLUSIONS@#Children with GFAP-A often have non-specific clinical symptoms and show good response to immunotherapy. Children with overlap syndrome have a high recurrence rate, and early application of immunosuppressants may help to prevent recurrence and alleviate symptoms.

RESUMEN

  Objective  To investigate the clinical features of autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy.  Methods  We collected and analyzed the clinical and laboratory data and obtained the clinical characteristics of diagnosis and treatment from fifteen patients with positive GFAP antibody tested by cerebrospinal fluid and diagnosed autoimmune GFAP astrocytopathy by the multi-centers.  Results  The mean age of the first onset of autoimmune GFAP astrocytopathy was 39.73 years old (range 4-65 years), with no significant gender difference. In terms of clinical manifestations, we found the whole brain symptoms including abnormal mental behavior, disturbance of consciousness, epileptic attack accounting for more than 50, , meningitis accounting for 66.7%, myelitis (53.3%), limb tremor (53.3%), vision loss (33.3%); systemic symptoms including fever(100%) and fatigue(86.7%). 46.7% of patients were initially diagnosed with tuberculous meningoencephalitis and were treated with diagnostic antituberculous therapy. The MRI showed 46.7% of patients showed brain linear perivascular radial gadolinium enhancement in the white matter perpendicular to the ventricle.  Conclusions  Autoimmune GFAP astrocytopathy are acute or subacute dieases and the main clinical features include encephalitis, meningitis, myelitis and optic neuritis. They are likely to be misdiagnosed as tuberculous meningoencephalitis and can manifest progressive loss of consciousness in early phase, which is even life threatening.

RESUMEN

Autoimmune glial fibrillary acidic protein astrocytopathy(GFAP-A) is a novel form of autoimmune meningo-encephalitis resulted from auto-antibodies to GFAP, which may involve meninges, brain, spinal cord and optic nerves.Clinical presentations and outcomes in children are similar with those in adults.Compared with adults with GFAP-A, autonomic dysfunction, brain stem dysfunction or co-existing NMDAR encephalitis are more frequently in children, whereas malignancy and relapse are more commonly seen in the adults.GFAP-IgG level detected in cerebrospinal fluid is a specific biomarker of autoimmune GFAP-A.Corticosteroid-responsiveness is also a hallmark of autoimmune GFAP-A.
