Epstein-Barr Virus Antibodies in Egyptian Patients With Multiple Sclerosis
An observational study of Multiple Sclerosis and Epstein-Barr Virus Infections, run by Assiut University.
Trial summary
Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system that causes variable degrees of neurological disability. Epstein-Barr virus (EBV) has been identified as an important environmental factor implicated in the pathogenesis and progression of MS. Read more about this study

About this study
Official title: Frequency and Clinical Significance of Epstein-Barr Virus Antibody Titers in Egyptian Patients With Multiple Sclerosis
Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system that causes variable degrees of neurological disability. Epstein-Barr virus (EBV) has been identified as an important environmental factor implicated in the pathogenesis and progression of MS. However, the serological profile, antibody titers, and clinical relevance of EBV infection among Egyptian individuals with MS remain limited.
The primary purpose of this hospital-based observational study is to evaluate the frequency and titers of EBV-specific antibodies, specifically anti-viral capsid antigen (anti-VCA) IgG and anti-Epstein-Barr virus nuclear antigen 1 (anti-EBNA1) IgG, in Egyptian patients diagnosed with MS compared with age- and sex-matched healthy controls. The study also aims to assess whether EBV antibody levels correlate with MS disease activity, degree of neurological disability, relapse frequency, clinical subtype, brain MRI lesion burden, and response to disease-modifying therapies (DMTs).
A total of 140 participants will be enrolled at the Department of Neurology and Psychiatry, Assiut University Hospital, comprising 70 adult patients with MS diagnosed according to the 2024 McDonald criteria and 70 matched healthy controls. Participants will undergo clinical and demographic assessment, neurological disability evaluation using the Expanded Disability Status Scale (EDSS) for MS patients, and review of existing brain MRI scans. A single venous blood sample will be collected from all participants to measure anti-VCA IgG and anti-EBNA1 IgG levels using enzyme-linked immunosorbent assay (ELISA).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Multiple Sclerosis Group | 70 adult Egyptian patients aged 18-55 years diagnosed with multiple sclerosis according to the 2024 McDonald criteria. Participants will undergo clinical and neurological assessment (including Expanded Disability Status Scale [EDSS] scoring, disease duration, relapse history, and disease-modifying therapy response), review of available brain MRI scans for lesion load and distribution patterns, and venous blood sampling for serological measurement of anti-VCA IgG and anti-EBNA1 IgG antibodies using ELISA. | |
| Healthy Control Group | 70 age- and sex-matched apparently healthy individuals aged 18-55 years without history of multiple sclerosis, malignancy, viral hepatitis, HIV, or other immunosuppressive disorders. Participants will undergo demographic evaluation and venous blood sampling for serological measurement of anti-VCA IgG and anti-EBNA1 IgG antibodies using ELISA to serve as a comparison cohort. |
What is being measured
The primary outcome is the main question the study is designed to answer.

Secondary outcomes (2)
Serum Anti-VCA IgG Antibody Titers
Quantitative or semi-quantitative antibody titer/index values of anti-viral capsid antigen (VCA) IgG determined by ELISA microplate reader optical density measurements.
