Two patients with rheumatoid arthritis and one with Sjögren syndrome had a severe sensorimotor neuropathy preceding or up to 5 years after the onset of the disease. Electrophysiologic and sural nerve biopsy studies revealed an axonal neuropathy. Myelinated fibers were affected to a greater extent than unmyelinated axons. Peripheral nerve damage was related to occlusion of the vasa nervorum, since vasculitic involvement of epineurial vessels was observed in all patients. Despite the severity of the neuropathy, it may recover, because, compared with axons, Schwann cells are perhaps less vulnerable to ischemia.
两名类风湿关节炎患者和一名干燥综合征患者在疾病发作前或发病后长达5年出现严重的感觉运动神经病变。电生理和腓肠神经活检研究显示为轴索性神经病变。有髓纤维比无髓轴突受影响的程度更大。周围神经损伤与神经滋养血管闭塞有关，因为在所有患者中均观察到神经外膜血管的血管炎累及。尽管神经病变严重，但仍可能恢复，因为与轴突相比，雪旺细胞可能对缺血的耐受性更强。
