Gemcitabine is an antineoplastic used to treat several malignancies including pancreatic cancer. Its toxicity profile is well known with myelotoxicity, increased vascular permeability and peripheral oedema as most frequent adverse events. However, several cases of acute renal failure have been reported and haemolytic uremic syndrome (HUS) seems to be the underlying process. The cause of HUS remains unknown but its consequences can be lethal. Therefore, a high grade of suspicion is crucial to diagnose it and promptly treat it. This hopefully will reduce its morbidity. HUS is characterized by progressive renal failure associated with microangiopathic haemolytic anaemia and thrombocytopenia. The primary event is damage to endothelial cells and thrombotic microangiopathy (TMA) is the histopathological lesion. TMA affects mainly renal microvasculature. However, some cases evolve with central nervous or cardiovascular systems involvement. We present here a case of gemcitabine-induced HUS, with renal and cardiovascular system affected at the time of diagnosis which to our knowledge this is the first time of such case to be reported.
吉西他滨是一种用于治疗包括胰腺癌在内的多种恶性肿瘤的抗肿瘤药物。其毒性特征众所周知,骨髓毒性、血管通透性增加和外周水肿是最常见的不良事件。然而,已有数例急性肾衰竭的报道,溶血性尿毒症综合征(HUS)似乎是其潜在病因。HUS的病因尚不清楚,但其后果可能是致命的。因此,高度怀疑对于诊断和及时治疗至关重要。这有望降低其发病率。HUS的特征是进行性肾衰竭伴微血管病性溶血性贫血和血小板减少。主要事件是内皮细胞损伤,血栓性微血管病(TMA)是组织病理学病变。TMA主要影响肾微血管。然而,一些病例会累及中枢神经系统或心血管系统。我们在此报告一例吉西他滨诱导的HUS,诊断时肾脏和心血管系统均受影响,据我们所知,这是首次报道此类病例。
