Serum measles antibodies in multiple sclerosis

Area of Science:

• Immunology
• Neurology
• Virology

Background:

• Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system.
• The potential role of viral infections, such as measles, in the etiology of MS remains an area of investigation.

Purpose of the Study:

• To investigate measles virus antibody titers in patients with multiple sclerosis.
• To compare measles antibody levels between MS patients, their siblings, and healthy controls.

Main Methods:

• Serum samples from 80 MS patients, 20 siblings, and 990 healthy controls were analyzed.
• Haemagglutination inhibition (HI) assays were used to measure measles virus antibody titers.
• Cerebrospinal fluid (CSF) was also examined for measles antibodies in a subset of patients.

Main Results:

• Significantly higher measles HI antibody titers were observed in MS patients compared to healthy controls.
• No significant difference in measles HI antibody titers was found between MS patients and their siblings.
• Measles HI antibody titers decreased with age in healthy controls but not in MS patients.
• Low measles antibody titers were detected in the CSF of six MS patients, but not in control patients.

Conclusions:

• Elevated measles virus antibody titers may be associated with multiple sclerosis.
• The findings suggest a potential link between measles virus and MS pathogenesis, warranting further investigation.
• The presence of measles antibodies in CSF of MS patients warrants further study.
