摘 要:目的观察水通道蛋白(AQP4)抗体对视神经脊髓炎(NMO),高危NMO(HR.NMO)及多发性硬化(MS)等中枢神经系统炎性脱髓鞘疾病诊断及复发的预测价值。方法收集解放军总医院2008年5月至2012年5月352例中枢神经炎性脱髓鞘患者的临床资料,NMO患者106例,HR.NMO84例包括视神经脊髓型MS(OSMS),纵向扩展的横贯性脊髓炎(LETM),复发性视神经炎(RON)及伴有自身免疫病的视神经炎(ON)和脊髓炎(TM),经典MS患者162例,采用间接免疫荧光法检测患者血清AQP4抗体,并进行长期随访。结果352例中枢神经炎性脱髓鞘患者中,AQP4抗体阳性率31.3%。AQP4抗体阳性患者中有72(65.5%)例伴有严重的ON,82(74.5%)例伴有TM,60(54.4%)例脊髓病变超过3个椎体节段,16(14.5%)例在2年随访中发展为ON的复发,38(34.5%)例TM的复发。在抗体阳性与阴性患者中伴有严重的ON,TM,脊髓病变超过3个节段,发展为ON及TM的复发方面两组间差异均有统计学意义(均P〈0.05)。AQP4抗体阳性的NMO患者(n=78),随访后28(35.9%)例患者有TM的复发。而AQP4抗体阳性的HR—NMO患者(rt=28),随访后4(14.3%)例患者有ON的复发,10(35.7%)例有TM的复发。两年随访中,110例AQP4抗体阳性患者有57例有复发(ON或者TM),而242例阴性患者仅有17例有复发,两组差异有统计学意义(P〈0.05)。结论AQP4抗体阳性患者与阴性患者相比,多伴有严重ON,TM,长脊髓病变,且更易发展为ON或TM的复发。不论是AQP4抗体阳性的NMO还是HR.NMO患者,随访后多容易复发。AQP4抗体检测对中枢神经系统脱髓鞘疾病的诊断及预后评估有一定价值。Objective To determine the prognostic value of AQP4 antibody in the cohort of Chinese patients with neuromyelitis optica (NMO), HR-NMO( high-risk NMO)and classic multiple sclerosis (MS). Methods Sera of patients with NMO, HR-NMO and MS were all investigated for the presence of AQP4 antibody by indirect immunofluorescence in human AQP4-transfected ceils. The diagnostic and prognostic values of anti-AQP4 antibody were evaluated in 352 patients with NMO ( n = 106), HR-NMO ( n = 84) including optico-spinal MS (OSMS), longitudinally extensive transverse myelitis (LETM), recurrent optic neuritis (RON) and optic neuritis (ON) or transverse myelitis (TM) with other antoimmune disease and classic MS (n = 162). All patients were followed up at outpatient clinics or by telephone. Results In our study, the anti-AQP4 antibody's seropositivity in all demyelinating cases (n = 352) was 31.3%. And 72 (65.5%) seropositive patients presented with severe ON, 82(74. 5% ) with TM, 60(54. 4% ) with spinal- cord lesion more than 3 segments, 16( 14. 5% ) had relapses of ON and 38(34. 5% ) relapses of TM during a follow-up period of 24 months. Significant differences existed between anti-AQP4 antibody seropositivity and seronegative in terms of concurrent severe ON, TM, spinal-cord lesion more than 3 segments and relapses of ON and TM ( P 〈 0. 05 ). Also, in NMO patient seropositive for anti-AQP4 antibody ( n = 78), 28 (35.9%) developed relapses of TM. However, in HR-NMO patient with seropositivity ( n = 28 ), 4 ( 14. 3% ) developed relapses of ON and 10(35.7% ) relapses of TM. The relapse of ON or TM occurred in 57/110 seropositive patients versus 17/242 seronegative ones ( P 〈 0. 05 ). Conclusion As compared with anti- AQP4 antibody-negative ones, anti-AQP4 antibody-positive patients show significantly higher frequencies of severe ON, TM, longitudinal spinal-cord segments and they are more predisposed to ON or TM relapse.
