OBJECT: CD27 belongs to the tumor necrosis factor receptor family and is constitutively expressed on T cells. The concentration of cerebrospinal fluid (CSF) soluble (s)CD27 is elevated in patients with multiple sclerosis (MS). However, whether the level of CSF sCD27 is elevated in neuromyelitis optica spectrum disorder (NMOSD) remains unknown. The aim of this study was to measure the CSF concentration of sCD27 and to determine its relationship with NMOSD disease activity.
METHODS: CSF CXCL13 was measured by ELISA in neuromyelitis optica (NMO) (n = 31) and MS (n = 23) patients and in controls (CTLs) (n = 22).
RESULTS: The concentration of sCD27 was higher in the NMO group than in the MS (p = 0.082) and CTL (p = 0.002) groups, and there was a positive correlation with CSF IL-6 (p = 0.000) and a negative correlation with IL-10 (p = 0.073). In the NMO group, patients with higher sCD27 concentrations exhibited worse disease disability in their CSF (p = 0.006). Moreover, the sCD27 concentrations had a significantly positive correlation with the level of CSF total protein (p = 0.030). Furthermore, the patients positive for AQP4-IgG (n = 26) seemed to have higher levels of sCD27 in their CSF (p = 0.069) than those negative for AQP4-IgG (n = 5).
CONCLUSIONS: We revealed that the level of CSF sCD27 was elevated in NMOSD and correlated with NMOSD disease activity.
