BACKGROUND: Severe acute graft-versus-host disease (aGVHD) of the gut is a serious and frequent posttransplantation event associated with a high mortality rate. We report on our experience with factor XIII replacement in patients with severe aGVHD of the bowel after allogeneic hematopoietic stem cell transplantation. METHODS: Twenty-seven patients after allogeneic stem cell transplantation and severe aGVHD of the gut were enrolled. All patients suffered from bloody diarrhea that required packed red blood cell infusions. All patients received high-dose immunosuppression in combination with coagulation factor XIII (5,000 units initially, followed by 20 IU/kg body weight three times a day) for up to 3 weeks. RESULTS: After 8 days of factor XIII replacement and unchanged high-dose immunosuppression, we observed a significant reduction in the red blood cell requirement of 21 patients. CONCLUSION: We conclude that factor XIII replacement might be a useful supplementation in the treatment of aGVHD of the bowel.
