We describe the case history of three patients with meningoencephalitis who were initially treated for presumed tuberculous meningoencephalitis before being diagnosed with autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy. We highlight the overlapping clinical features between autoimmune GFAP astrocytopathy and tuberculous meningoencephalitis and the challenges in early diagnosis, as both entities respond to an initial course of steroids accompanying antituberculous medications. Early evaluation of GFAP-immunoglobulin G in the cerebrospinal fluid of patients who present with aseptic meningoencephalitis could reveal autoimmune GFAP astrocytopathy, which responds favorably to immunotherapy.

A spectrum of neurological diseases with elevated cerebrospinal fluid adenosine deaminase levels.
J Neurol Sci

Department of Neurology, Graduate School of Medicine, Chiba University, Chiba, Japan.
Article Synopsis
- This study investigated how adenosine deaminase (ADA) levels in cerebrospinal fluid (CSF) relate to different neurological disorders.
- Five specific diseases showed significantly higher CSF ADA levels compared to a noninflammatory control group, with tuberculous meningitis (TBM) showing the highest increase.
- Strong positive correlations were found between CSF ADA levels and several other laboratory parameters, suggesting that elevated ADA levels might indicate T-cell hyperactivation in the central nervous system.

Virus encephalitis (VE), recognized as one of the common kinds of central nervous system (CNS) diseases after virus infection, has a surprising correlation with autoimmune encephalitis (AE) when autoimmune antibodies emerge in cerebrospinal fluid (CSF) or serum. Herpes simplex virus and Epstein-Barr virus are the most critical agents worldwide. By molecular mimicry, herpes viruses can invade the brain directly or indirectly.

Objective: Autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) is a novel steroid sensitive autoimmune disease, without a diagnostic consensus. The purpose of this study was to improve early GFAP-A diagnosis by increasing awareness of key clinical characteristics and imaging manifestations.
Methods: Medical records of 13 patients with anti-GFAP antibodies in serum or cerebrospinal fluid (CSF) were reviewed for cross-sectional and longitudinal analysis of clinical and magnetic resonance imaging (MRI) findings.

The signaling pathways behind severe astrocytic lysis with Aquaporin4 auto-antibody (AQP4-IgG) seropositivity, and reactive astrocytosis with myelin oligodendrocyte glycoprotein auto-antibody (MOG-IgG) seropositivity, remain largely unexplored in Neuromyelitis optica spectrum disorder (NMOSD), while almost no molecular details being known about double-seronegative (DN) patients. Recent discovery of glial fibrillary acidic protein (GFAP) in DN NMOSD patients' cerebrospinal fluid, akin to AQP4-IgG + ve cases, suggests astrocytopathy. Here, we aim to study small non coding RNA (sncRNA) signature alterations in astrocytes exposed to AQP4-IgG + ve and MOG-IgG + ve patient sera, and their potential resemblance with DN-NMOSD.

Article Synopsis
- This study investigates the clinical and MRI characteristics of children with autoimmune GFAP astrocytopathy, revealing limited data compared to what is known in adults.
- Researchers analyzed cases of 15 children from various clinical centers, finding common symptoms like acute encephalitis and meningitis, and specific MRI patterns in all cases.
- The findings suggest that GFAP antibodies lead to distinct clinical and imaging features, emphasizing the need for testing in pediatric patients with similar symptoms, especially those with brainstem involvement.
