Abstract
Livedoid vasculopathy (LV) is a thrombo-occlusive vascular disease with an uncertain aetiology. In addition to cutaneous manifestations, LV patients may develop peripheral neuropathy. This study aimed to examine features of peripheral neuropathy in Chinese LV patients. We retrospectively reviewed and analysed the clinical data of 55 LV patients treated at Peking Union Medical College Hospital and conducted a literature review of peripheral neuropathy in LV patients. The incidence of peripheral neuropathy in our cohort was 12.73%. Among the seven patients with neuropathy, five were women and two were men. Median age at enrollment and disease onset in these patients was 27.29 and 22.57 years, respectively. Mean time from the appearance of cutaneous manifestations to the development of neurological symptoms was 38.67 months. Peripheral neuropathy was generally refractory to treatment, asymmetric in the distal extremities, and slowly progressive. The main symptom was numbness; hypoesthesia and neuromuscular manifestations occurred occasionally. The proportion of patients reporting seasonal worsening of symptoms was significantly higher in LV patients with peripheral neuropathy than in LV patients without neuropathy (P < .05). Peripheral neuropathy is a potential complication of LV. LV patients with peripheral neuropathy require long-term follow-up.
