We studied 33 consecutive patients with systemic lupus erythematosus(SLE) for neuropathy by employing the Neuropathy Symptom Score(NSS),Neurological Disability Score(NDS),EMG and nerve conduction velocity(NCV)studies,and determinations of vibration thresholds(VT).Polyneuropathy defined as NCV abnormalities of two or more nerves occurred in seven patients(21%). Neuropathic symptoms showed a poor correlation with NCV and VT,while clinical neuropathic signs,VT,and NCV correlated with each other in most instances.When reporting frequencies of neuropathy in SLE,NCV studies should be used as a basis.NSS,NDS,and VT give additional quantifiable information and can be useful in the follow-up of patients and for evaluating the response to therapy. |
