Thrombotic microangiopathy (TMA) associated with injecting sustained-release oxymorphone, an opioid intended for oral use, has previously been reported. We report a case of TMA secondary to intravenous use of sustained-release oxycodone, and the first case to demonstrate relapsing disease due to persistent intravenous opioid use. In cases such as these, TMA is suspected to be due to a polyethylene oxide (PEO) coating found on these drugs, and the disease is likely due to a directly toxic effect of PEO to endothelial cells. We hypothesize that there are unidentified genetic predispositions causing some persons to be susceptible to developing this disease.
此前已有报道,与注射用于口服的阿片类药物缓释羟吗啡酮相关的血栓性微血管病(TMA)。我们报告一例因静脉使用缓释羟考酮继发的TMA病例,这也是首例因持续静脉使用阿片类药物而出现疾病复发的病例。在这类病例中,TMA被怀疑是由于这些药物上发现的聚环氧乙烷(PEO)涂层所致,该病可能是由于PEO对内皮细胞的直接毒性作用。我们推测,存在一些未被识别的遗传易感性因素,导致一些人易患此病。
