Successful management of germanium poisoning-induced multiple organ dysfunctions by combined blood purification therapy.

Background: Blood purification therapy has not been applied in the detoxification of germanium compounds. This report described a case of germanium poisoning with renal failure, liver dysfunction, and acute pancreatitis which was successfully treated by continuous venovenous hemodiafiltration (CVVHDF) combined with plasmapheresis.Case report: A 58-year-old male was admitted to a local hospital due to polydipsia, polyuria, and weight loss for 2 months. The patient was definitely diagnosed with germanium poisoning and was treated with blood purification therapy, CVVHDF combined with plasmapheresis. The blood and urinary germanium concentrations decreased rapidly during the first week after the combined blood purification therapy. The blood germanium concentration gradually reduced to within the normal range within the next three weeks and fluctuated at a normal level. However, the urinary germanium concentration exceeded the normal level after three months, indicating an accumulation of germanium in the organs and tissues. The patient's clinical symptoms ameliorated and the functions of kidney, liver and pancreatitis gradually recovered.Conclusion: Combined CVVHDF with plasmapheresis is an effective treatment for germanium poisoning and the associated multiple organ dysfunctions.
