Abstract:
Objective:To compare the characteristics of cerebrospinal fluid (CSF) oligoclonal band electrophoresis examination results between patients with multiple sclerosis (MS) and Guillain-Barré syndrome (GBS), and to provide a basis for the differential diagnosis of the two types of neurological demyelinating diseases.Methods:Case analysis.The retrospective study method was used, and the patients who visited Beijing Tiantan Hospital, Capital Medical University from January 2020 to August 2023 were selected as the research subjects, including 70 MS patients[19 males and 51 females, aged 34 (28, 44) years] and 70 GBS patients [44 males and 26 females, aged 50 (36, 61) years]. The oligoclonal band electrophoresis and immunoglobulin G(IgG) index (IgG I) were performed on the clinical specimens from MS and GBS patients, and CSF routine, CSF biochemistry (glucose, chloride, protein), lactate, interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α), antibodies to herpes simplex virus (HSV), cytomegalovirus (CMV), rubella virus (RV), toxoplasma gondii (TOX), Epstein-Barr virus (EBV), and coxsackievirus were detected simultaneously. The enumeration data were treated with the chi-square test. The measurement data didn′t accord with normal distribution, and were treated with the Mann-Whitney U test. Results:The positive rate of oligoclonal band (OCB) electrophoresis in MS and GBS patients were 80.00% (56/70) and 4.29% (3/70), respectively. The positive rate in MS patients was significantly higher than that in GBS patients (χ 2=82.289, P<0.001). The white blood cells count [5.50 (3.00, 11.00)/μl] and the level of chlorine [127 (125, 128) mmol/L] in CSF of MS patients was higher than that of GBS patients [3.50(2.00, 7.00)/μl, 126(124, 128) mmol/L] ( U=-2.245, P<0.05; U=-2.028, P<0.05), while the levels of CSF protein [33.40(27.61, 39.17)mg/L], glucose [3.59(3.36, 3.88) mmol/L], and lactate [1.55(1.40, 1.73) mmol/L] of MS patients were lower than those of GBS patients [6.71(43.78, 138.30) mg/L, 3.97(3.55, 4.54) mmol/L, 1.80(1.60, 2.00) mmol/L]( U=-6.747, P<0.001; U=-3.651, P<0.001; U=-4.531, P<0.001). The levels of IL-6 [3.36(2.34, 5.02) pg/ml], IL-8 [55.40(46.75, 66.40) pg/ml], and TNF-α [5.63(4.25, 6.63) pg/ml] in CSF of MS patients were lower than those of GBS patients [6.12(3.61, 11.73) pg/ml, 120.00(74.90, 187.80) pg/ml, 6.57(5.25, 8.03) pg/ml]( U=-3.463, P<0.05; U=-5.225, P<0.001; U=-2.785, P<0.05). The positive rates of CMV IgG, TOX IgG, and EBVCA IgG in CSF of MS patients were 36.36% (24/66), 0 and 0, respectively,and the positive rates of those of GBS patients were 85.71% (54/63), 30.16% (19/63), and 19.05% (12/63), respectively. The positive rates of CMV IgG, TOX IgG, and EBVCA IgG in CSF of MS patients were significantly lower than those of GBS patients (χ 2=32.839, P<0.001; χ 2=23.343, P<0.001; χ 2=13.861, P<0.001). Conclusions:The MS patients mainly showed the higher positive rates of OCB. The GBS patients showed elevated CSF protein levels but no significant increase in white blood cell count, namely albuminocytologic dissociation in CSF. Meanwhile, the GBS patients showed elevated levels of intrathecal immunity and inflammation indicators, and a higher positive rate of pathogen antibodies.
