title: Effect of IgM-enriched intravenous immunoglobulin (Pentaglobin) on endotoxaemia and anti-endotoxin antibodies in bone marrow transplantation.
abstract: Endotoxin was measured in over 1000 plasma samples from bone marrow transplant patients in a randomized trial of the IgM-enriched intravenous immunoglobulin (IVIG) Pentaglobin. Peak endotoxaemia was significantly reduced (P = 0.02) in patients receiving Pentaglobin and 70% of all pyrexias of unknown origin were associated with endotoxaemia. Gut mucosal damage, assessed by lactulose/mannitol ratios, was significantly associated (P = 0.02) with endotoxaemia. Specific IgM antibody to endotoxin core-glycolipid was significantly raised (P < 0.01) in patients receiving the IVIG, and the IgM fraction of Pentaglobin was found to contain most of the anti-endotoxin antibody activity of the IVIG. These results suggest a role for IgM-enriched IVIG as a prophylactic agent for the reduction of endotoxaemia and its consequences in bone marrow transplant patients.
