To describe clinical, anamnestic and neurophysiological features of patients with atypical variants of chronic inflammatory demyelinating polyneuropathy, characterized by benign disease course, minimal motor involvement and not required pathogenic therapy.Materials and methods. 8 patients (7 men (87 %) and 1 woman (13 %) at the age of 52–77 years) with atypical variants of chronic inflammatory demyelinating polyneuropathy were analyzed: 5 patients (62.5 %) with asymmetric variant – multifocal acquired demyelinating sensorimotor neuropathy and 3 patients (37.5 %) with sensory variant. All patients were observed at the Research Center of Neurology for the period of 2016– 2019. In each patient the proper clinical and laboratory evaluation was performed along with nerve conduction study and nerve ultrasound.Results. The disease duration at the time of first visit was 1–8 years. By INCAT disability score 3 (37.5 %) patients had 0 points (normal), 3 (37.5 %) patients – 1 point and 1 patient had 2 (25 %) points. Nerve conduction study showed multifocal, asymmetric demyelinating changes in motor nerves. For the whole period of observation all patients were stable, so no one required pathogenic therapy.Conclusion. Chronic inflammatory demyelinating polyneuropathy is a clinically heterogeneous disorder, required clinical suspicion in all patients over 50 years with features of multiple nerve involvement; nerve conduction study helps to detect typical changes, including subclinical ones. The primary strategy of management typical and atypical disease variants in stable course and minimal symptoms is a case follow-up with precise assessment of advantages and disadvantages of pathogenic therapy.https://nmb.abvpress.ru/jour/article/view/383chronic inflammatory demyelinating polyneuropathyatypical variantmultifocal acquired demyelinating sensorimotor neuropathylewis–sumner syndromesensory variantnerve conduction study |
