Persistence of Inoue-Melnick virus and antibody in cerebrospinal fluid
Abstract:
Serial cerebrospinal fluid samples were obtained from 14 multiple sclerosis patients over a period of several months and were tested under code for Inoue-Melnick virus. In five of the positive patients, virus was present in 28 of 32 specimens collected over a period of 2 to 5 months. Four patients, from whom a total of 34 specimens were taken, yielded only a single isolate each. Five patients contributed 28 specimens, all of which were negative. In six patients (three virus positive and three virus negative), neutralizing antibody was detected in serum and in cerebrospinal fluid.
Insights
This study investigated the presence of Inoue-Melnick virus in multiple sclerosis patients. The virus was detected in cerebrospinal fluid of some patients, with associated neutralizing antibodies found in both serum and cerebrospinal fluid.
Area of Science:
- Virology
- Neurology
- Immunology
Background:
- Multiple sclerosis (MS) is a chronic neurological disease.
- The potential role of viral infections in MS pathogenesis is an ongoing area of research.
- Inoue-Melnick virus (IMV) is a less-studied virus with an unknown association to neurological conditions.
Purpose of the Study:
- To investigate the presence and persistence of Inoue-Melnick virus in cerebrospinal fluid (CSF) of multiple sclerosis patients.
- To determine if neutralizing antibodies against IMV are present in the serum and CSF of these patients.
Main Methods:
- Serial CSF samples were collected from 14 MS patients over several months.
- Samples were tested for the presence of Inoue-Melnick virus under code.
- Neutralizing antibodies against IMV were assessed in serum and CSF.
Main Results:
- Inoue-Melnick virus was detected in CSF samples from 5 out of 14 MS patients.
- Virus was present in 28 of 32 specimens from positive patients over 2-5 months.
- Neutralizing antibodies were detected in 6 patients (3 virus-positive, 3 virus-negative).
Conclusions:
- Inoue-Melnick virus can be present in the cerebrospinal fluid of multiple sclerosis patients.
- The virus may persist for several months in some individuals.
- The presence of neutralizing antibodies suggests an immune response to IMV in MS patients, irrespective of detectable virus.
