AI Article Synopsis
- Multiple sclerosis (MS) is a chronic disease of the central nervous system influenced by genetic and environmental factors, particularly Epstein-Barr virus (EBV) infection, which may play a direct role in its development.
- This study assessed whether EBV antibody levels in serum and cerebrospinal fluid (CSF) could assist in diagnosing MS by comparing levels in relapsing-remitting MS patients, optic neuritis patients, and healthy controls.
- The results showed higher EBV antibody levels in MS patients, suggesting these antibody indices could enhance current diagnostic methods for the disease.
Article Abstract
Background: Multiple sclerosis (MS) is a chronic central nervous system (CNS) disease, which is diagnosed by a combination of clinical symptoms and magnetic resonance imaging and measurement of an increased intrathecal antibody synthesis. Genetic as well as environmental factors influence onset of the disease, where especially Epstein-Barr virus (EBV) infection is directly involved in MS development. In this open retrospective study, we aimed to elaborate whether various serum and cerebrospinal fluid (CSF)-based EBV antibody indices may aid in the diagnosis of MS.
Methods: Epstein-Barr nuclear antigen (EBNA)1 IgG concentrations in serum and CSF of relapsing-remitting (RR)MS patients (n=61) (M:F 28:33, average 40 years), optic neuritis patients (n=26) (M:F 9:17, average 47 years) and healthy controls (HCs) (n=15) (M:F 8:7, average 43 years) were determined by enzyme-linked immunosorbent assay. The obtained EBNA1 IgG levels were compared to factors such as total IgG, albumin concentrations, specific antibody index, and various serum- and CSF-based indices.
Results: Significantly elevated EBNA1 IgG levels were detected in serum and CSF of RRMS patients compared to HCs. CSF EBNA1 IgG and indices based on specific CSF EBNA1 IgG associated with CSF albumin or serum EBNA1 IgG associated with total serum IgG obtained the highest sensitivities and complemented the IgG index and oligoclonal bands.
Conclusion: These findings indicate that aforementioned indices may supplement existing indices and aid in the diagnosis of MS.

Background: A strong association between multiple sclerosis (MS) and Epstein-Barr virus (EBV) has been established but the exact role of EBV in MS remains controversial. Recently, molecular mimicry between EBNA1 and specific GlialCAM, CRYAB and ANO2 peptides has been suggested as a possible pathophysiological mechanism. The aim of this study was to analyse anti-EBV antibodies in MS patients against (I) EBV lifecycle proteins, (II) putative cross-reactive peptides, and (III) during treatment.

Background: Epstein-Barr virus (EBV) infection increases the risk of having multiple sclerosis (MS). Data on adults with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are lacking.
Objective: To compare EBV serological status in MOGAD versus MS.

Given the association of Epstein-Barr virus (EBV) with subjective perception of fatigue and demyelination in clinical conditions, the question about potential subclinical effects in the adult general population remains open. We investigate the association between individuals' EBV immune response and perceived fatigue in a community dwelling cohort (n = 864, age 62 ± 10 years old; 49% women) while monitoring brain tissue properties. Fatigue levels are assessed with the established fatigue severity scale, the EBNA-1 and VCA p18 immunoglobulin G (IgG) chronic response - with multiplex serology and the estimates of local brain volume, myelin content, and axonal density - using relaxometry- and multi-shell diffusion-based magnetic resonance imaging (MRI).

Introduction: Epstein‑Barr virus (EBV) reactivation is increasingly recognized as a potential exacerbator of autoimmune diseases, including Hashimoto thyroiditis (HT).
Objectives: This study examined the association between EBV reactivation and intracellular Toll‑like receptor (TLR) expression in newly‑diagnosed, untreated HT patients. Its aim was to determine whether EBV reactivation and expression of specific TLRs (TLR3, TLR7, TLR8, and TLR9) contribute to the pathogenesis and progression of HT.
