Systematic review of colchicine neuromyopathy: Risk factors, duration and resolution
Abstract
OBJECTIVE: To identify reports of colchicine-induced neuropathy and myopathy and ascertain risk factors associated with this toxicity at commonly used doses.
METHODS: A systematic review of case reports was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA methodology). PubMed and EMBASE were searched through October 2021 for case reports of neuropathy and/or myopathy associated with the use of colchicine at therapeutic doses.
RESULTS: A total of 143 cases of neuromyopathy from 99 articles were identified as having a "definite" or "probable" association with colchicine usage, as assessed by the Naranjo algorithm. Most of these cases presented with features of both neuropathy and myopathy (n=72, 51%) but symptoms of myopathy were predominant. The mean total daily dose was 1.25±0.60 mg and 48% had been taking colchicine for more than 12 months before presenting with neuromyopathy. A total of 117 (82%) of all reports had either a significant co-morbidity or possible colchicine drug-drug interaction, while 57 (40%) had both risk factors. A total of 26 cases (18%) had no significant risk factor but only 15 of these reports contained complete descriptions of the patient's co-morbidities and co-medications. Cessation of colchicine generally led to complete resolution of symptoms in 70% of cases within a median of 21 days. There were 3 deaths reported which were due to multi-organ failure despite cessation of colchicine and…
