Measles virus-specific IgG in cerebrospinal fluid in multiple sclerosis

Area of Science:

• Neurology
• Immunology
• Virology

Background:

• Multiple sclerosis (MS) is a chronic neurological disease.
• The role of viral infections, such as measles, in MS pathogenesis is under investigation.
• Measles virus-specific antibodies in cerebrospinal fluid (CSF) can indicate past infection or immune response.

Purpose of the Study:

• To compare the prevalence of measles virus-specific IgG in the CSF of patients with MS versus other neurological diseases and healthy controls.
• To assess the impact of sample concentration on measles IgG detection in CSF.

Main Methods:

• Cerebrospinal fluid (CSF) samples were collected from patients with MS, other neurological diseases, and normal controls.
• CSF samples were analyzed for the presence of measles virus-specific IgG.
• Samples were tested both in their original state and after a fivefold concentration.

Main Results:

• Measles virus-specific IgG was detected in 58.1% of MS patients and 24.1% of patients with other neurological diseases.
• No measles IgG was found in normal controls.
• Concentrating CSF samples increased detection rates to 80.6% in MS patients and 34.5% in other neurological disease patients.

Conclusions:

• The findings suggest a higher prevalence of measles virus-specific IgG in the CSF of MS patients.
• Concentration of CSF samples significantly enhances the detection of measles IgG.
• Further research is warranted to elucidate the potential role of measles virus in MS.
