Colloidal silver ingestion as an alternative medicine treatment is becoming more common. This case report describes a patient with potential silver poisoning and severe anemia.
A woman in her late sixties was transported to the emergency department because of progressive fatigue and nausea. She had been drinking 150 µg of colloidal silver daily for two to three weeks. Blood sampling revealed severe anemia (red blood cell count 48 g/L) and a whole-blood silver concentration of 20 µg/L. Liver function tests were abnormal and there were signs of incipient heart failure with increased pro-brain natriuretic peptide, troponin T, as well as pleural effusion. She was stabilized with blood transfusion and symptomatic treatment, to be discharged from the hospital after ten days. The patient improved over the following six weeks and the whole-blood silver concentration decreased to 3.3 µg/L after about three months.
The case demonstrates the potential effects of silver intake on the hematopoietic, hepatic, and cardiovascular systems. This highlights the possible risks associated with emerging alternative medicine therapies.
摄入胶体银作为一种替代医学疗法正变得越来越普遍。本病例报告描述了一名可能患有银中毒和严重贫血的患者。
一名60多岁的女性因进行性疲劳和恶心被送往急诊科。她连续两到三周每天饮用150微克胶体银。血液检查显示严重贫血（红细胞计数48克/升），全血银浓度为20微克/升。肝功能检查异常，有早期心力衰竭迹象，脑钠肽前体、肌钙蛋白T升高，还有胸腔积液。通过输血和对症治疗病情稳定，十天后出院。患者在接下来的六周内有所好转，大约三个月后全血银浓度降至3.3微克/升。
该病例显示了摄入银对造血、肝脏和心血管系统的潜在影响。这凸显了新兴替代医学疗法可能存在的风险。
