Objective Describe the clinical characteristics of patients with matched oligoclonal bands in paired cerebrospinal fluid (CSF) and serum samples.

Background One means by which a diagnosis of autoimmune central nervous system disease is supported is via identification of unique oligoclonal bands in the cerebrospinal fluid. Previously considered an incidental finding, some patients have matched IgG bands present in both the CSF and serum. The clinical significance of matched oligoclonal bands in the context of possible neuroimmunologic or systemic disease has not been thoroughly investigated.

Design/Methods Retrospective chart review of patients seen at University of Utah Health who had oligoclonal band analysis performed at ARUP Laboratories (Salt Lake City, UT) between January 1, 2015 and September 24, 2020. Only patients with matched or matched plus unique oligoclonal band results were analyzed. Clinical charts were reviewed by a neuroimmunologist.

Results We identified 502 patients with matched oligoclonal bands and 117 patients with matched plus unique oligoclonal bands. Those with matched oligoclonal bands only were more likely to be older (p<0.001) and to have systemic autoimmune disease (p 0.004). The most frequent coexisting systemic autoimmune diseases included hypothyroidism, systemic lupus erythematosus, and sarcoidosis. Patients with matched plus unique oligoclonal bands were more likely to have an abnormal MRI spine (p<0.001) and CSF pleocytosis (p<0.001). Patients with matched plus unique oligoclonal bands were more likely to have an inflammatory neurologic disease. Finally, in an adjusted logistic regression fit to death, there was a significant decrease in odds of death for those with matched plus unique oligoclonal bands compared to those with only matched bands (OR 0.52 [95% CI 0.29 - 0.94]).

Conclusions The presence of matched CSF and serum bands identifies a distinct population of patients as compared to patients with matched plus unique oligoclonal bands, and thus can assist clinicians in diagnostic evaluation, especially that of an autoimmune disorder.
