JAMA Neurol:多发性硬化的视网膜结构、鞘内免疫与临床病程的关系

2017-05-05 zhangfan MedSci原创

视网膜层可以反映多发性硬化病情的进展。GCIPL减少与鞘内B免疫细胞增加相关,是残疾恶化的独立危险因素,而INL水平与脑实质性活动有关。因此,视网膜光学相干断层扫描可能是一种对不同MS患者进行鉴别开展个体化治疗方案的手段

多发性硬化症(MS)患者的长期病情进展研究对于患者个体化治疗方案是十分重要的。近日研究人员就视网膜层体积与脑脊液中免疫细胞亚群和免疫球蛋白指数的相关性以及视网膜层体积单独或组合鞘内变量与MS患者病情进展的相关性进行研究。

研究招募了312名患者,其中病程短的72人作为第一组,病程较长的240人为第二组。对第一组的患者研究人员探讨常见的神经节细胞、内网状层(GCIPL)和内核层(INL)体积与免疫球蛋白指标和脑脊液中免疫细胞数的关系以及鞘内B细胞数与残疾恶化的关系,对于第一和二组患者研究内网状层体积与残疾恶化的关系。

研究招募的患者中67.9%为女性,平均年龄34岁。第一组中69.4%为女性,平均年龄31岁,平均病程1个月,研究发现GCIPL体积减少与鞘内B细胞增加(平均增加1.96%)以及鞘内IgG合成(平均脑脊液/血清IgG指数0.78)相关,INL体积与鞘内CD56自然杀伤细胞数量相关(r=0.28; P=0.007)。GCIPL体积低的患者(<1.99 mm3)其残疾恶化的风险提高6.4倍(95% CI, 1.7-24.2; P=0.007),该结果在第二组患者中也被证实。两组患者分析发现INL体积与前瞻性T2病变负荷和钆增强病变增加相关。

研究发现,视网膜层可以反映多发性硬化病情的进展。GCIPL减少与鞘内B免疫细胞增加相关,是残疾恶化的独立危险因素,而INL水平与脑实质性活动有关。因此,视网膜光学相干断层扫描可能是一种对不同MS患者进行鉴别开展个体化治疗方案的手段。
