BACKGROUND: Neuromyelitis optica spectrum disorders (NMOSD) and multiple sclerosis (MS) may be similar to each other in clinical features. The differential diagnosis between them remains challenging in clinical practice. This retrospective study is aimed to describe the difference of cerebrospinal fluid (CSF) lactate level between aquaporin-4 antibody (AQP4-Ab) positive NMOSD and MS, to discuss the possible explanation upon immunopathogenesis and the significance in differential diagnosis.
METHOD: We retrospectively analysed cerebral biochemical results from 60 AQP4-Ab positive NMOSD and 55 MS Asian patients. To assess the diagnostic ability of cerebrospinal fluid lactate for distinguishing AQP4-Ab positive NMOSD from MS using receiver operating characteristic (ROC) curve analysis.
RESULTS: The cerebrospinal fluid lactate level is significantly higher in AQP4-Ab positive NMOSD than in MS based on multiple linear regression (P<0.0001). The differential diagnostic efficacy of cerebrospinal fluid lactate distinguishing AQP4-Ab positive NMOSD from MS reached an area under ROC curve (AUC) of 0.8842 (95% CI 0.82-0.95, P<0.0001), using 1.50 as the diagnostic critical point of the cerebrospinal fluid lactate level, the sensitivity was 88.3%, the specificity was 78.2%.
CONCLUSION: The cerebrospinal fluid lactate level differs between AQP4-Ab positive NMOSD and MS, which also contributes in differential diagnosis. The distinct patterns of cerebral biochemical results may cast a light on the immunopathogenesis of AQP4-Ab positive NMOSD.
