Abstract:
Objective:To preliminarily analyze the relationship between peripheral blood CD19 +CD27 +B cells, CD4 -CD8 -double-negative T cells, related cytokines and recurrence in patients with neuromyelitis optica spectrum disorders (NMOSD). Methods:A retrospective analysis was performed on the clinical data of 72 patients with NMOSD admitted to Henan Provincial People′s Hospital between January 2019 and January 2021. According to presence or absence of recurrence within 1 year after treatment, they were divided into non-recurrence group ( n=30) and recurrence group ( n=42). The data such as gender, age and score of Extended Disability Status Scale (EDSS) at admission were collected. The levels of serum triglyceride (TG), total cholesterol (CHO), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (ApoA) 1 and apolipoprotein B (ApoB) were detected by full-automatic biochemical analyzer. The level of total protein in cerebrospinal fluid was detected by full-automatic programmed protein analyzer. The levels of immunoglobulin (Ig) G and IgM in cerebrospinal fluid were detected by immunoturbidimetry. The counts of peripheral blood CD19 +CD27 +B cells and CD4 -CD8 -double-negative T cells were detected by flow cytometry. The levels of serum interleukin (IL)-6, IL-10 and IL-2 were detected by enzyme-linked immunosorbent assay. Results:EDSS score, neutrophils, proportions of cases with positive aquaporin 4 (AQP4) antibody and autoimmune antibody in the recurrence group were significantly higher than those in the non-recurrence group (all P<0.05). There was no statistically significant difference in serum TG, HDL-C, LDH-C, ApoB, ApoA1, total protein in cerebrospinal fluid, IgG or IgM between the non-recurrence group and the recurrence group (all P>0.05). The proportions of CD19 +B cells, CD19 +CD27 +B cells and CD4 -CD8 -double-negative T cells in the recurrence group were (1.21±0.12)%, (1.61±0.17)% and (1.39±0.25)%, significantly higher than those in the non-recurrence group [(0.85±0.07)%, (1.25±0.12)%, (0.89±0.22)%, t=15.51, 3.89, 12.06, all P<0.05]. The counts of CD19 +B cells, CD19 +CD27 +B cells and CD4 -CD8 -double-negative T cells in the recurrence group were (289.50±17.64) ×10 6/L, (4.67±0.03) ×10 6/L and (64.78±6.53) ×10 6/L, significantly higher than those in the non-recurrence group [(254.56±15.34) ×10 6/L, (3.18±0.03) ×10 6/L, (47.82±4.83) ×10 6/L, t=14.27, 4.26, 12.06, all P<0.05]. The level of serum IL-10 in the recurrence group was lower than that in the non-recurrence group [(18.56±1.97) ng/ml vs (24.72±2.52) ng/ml, t=11.64, P<0.05], while levels of IL-6 and IL-2 were significantly higher than those in the non-recurrence group [(15.12±1.54) pg/ml vs (11.47±1.23) pg/ml, (28.34±2.94) pg/ml vs (22.57±2.36) pg/ml, t=10.75, 8.89, both P<0.05]. Conclusion:The levels of peripheral blood CD19 +CD27 +B cells, CD4 -CD8 -double-negative T cells and related cytokines are abnormal in NMOSD patients, which may be related to the recurrence of NMOSD.
