The linoleic acid depression (LAD) test for multiple sclerosis using the macrophage electrophoretic mobility (MEM)...

Area of Science:

• Immunology
• Neurology
• Metabolic studies

Background:

• Lymphocyte sensitization to thyroid antigen is detectable in multiple sclerosis (MS), other neurological diseases (OND), and normal individuals using the macrophage electrophoretic mobility (MEM) test.
• The MEM test with linoleic acid (MEM-LAD) reveals distinct patterns in neurological patients compared to controls.

Purpose of the Study:

• To investigate the diagnostic and characteristic potential of the MEM-LAD test in differentiating multiple sclerosis (MS).
• To explore the familial and etiological factors contributing to the observed metabolic phenomenon in MS.

Main Methods:

• Utilizing the macrophage electrophoretic mobility (MEM) test, specifically the MEM-LAD assay incorporating linoleic acid.
• Assessing the percentage of inhibition of positive MEM test results by linoleic acid across MS patients, OND patients, and normal subjects.
• Analyzing results from mothers of MS patients to investigate familial patterns.

Main Results:

• Linoleic acid demonstrated a high inhibition rate (95%) in MS patients, significantly higher than in normals (58%) and OND patients (45%).
• This high inhibition rate was consistent across all stages and forms of MS, irrespective of moderate immunosuppressive therapy.
• Mothers of MS patients exhibited an intermediate inhibition rate (78%), suggesting a genetic component alongside an exogenous factor.

Conclusions:

• The pronounced inhibition by linoleic acid in the MEM-LAD test is a characteristic feature of multiple sclerosis (MS).
• The findings suggest a familial (genetic) basis for this metabolic response in MS, with evidence pointing to an additional environmental influence.
• The study supports further clinical investigation of linoleic acid as a potential therapeutic agent for MS.
