Exploring the link between immunoglobulin deficiency and fatigue in multiple sclerosis patients

Immunoglobulin Deficiency a Treatable Cause of Fatigue in Patients With Multiple Sclerosis (MS)? - A Prospective Observational Fatigue Trial

Observational Insel Gruppe AG, University Hospital Bern · NCT05357781

This study is trying to see if low levels of a certain antibody in people with multiple sclerosis can be a cause of their fatigue and if treating it could help them feel better.

What this trial studies

This observational study aims to investigate whether hypogammaglobulinemia, characterized by low IgG serum levels, is a treatable cause of fatigue in patients with multiple sclerosis (MS). The primary objective is to establish a connection between hypogammaglobulinemia and fatigue, while the secondary objective focuses on understanding if fatigue is exacerbated by frequent infections in these patients. The study will involve laboratory tests to assess immunoglobulin levels in individuals diagnosed with MS who meet specific inclusion criteria. By identifying potential treatable factors contributing to fatigue, the study seeks to improve the quality of life for MS patients.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-65 with a stable diagnosis of multiple sclerosis and no significant psychiatric or immunodeficiency issues.

Not a fit: Patients with severe depression, other forms of immunodeficiency, or those already receiving immunoglobulin replacement therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new treatment options for fatigue in multiple sclerosis patients by addressing underlying immunoglobulin deficiencies.

How similar studies have performed: While studies have shown correlations between immunoglobulin therapy and fatigue in other conditions, this specific approach in multiple sclerosis is novel and has not been extensively tested.
