Successful Treatment of Gastrointestinal Bleeding With Recombinant Factor VIIa After Kidney Transplantation in Patients With Pancytopenia.

Abstract

Hemostatic disorders can often complicate transplantation procedures. Moreover, antihemmorhagic drugs may not efficiently control bleeding that occurs in such cases. We report on a patient who underwent kidney transplantation complicated by bone marrow aplasia and gastric bleeding who was succesfully treated with recombinant activated FVII (Novoseven). In May 2005, a 53-year-old man affected by chronic renal insufficiency underwent kidney transplantation. At the beginning of June, laboratory tests showed progressive reduction in the blood cell count with anemia, granulocytopenia, and thrombocytopenia related to the development of marrow insufficiency. We commenced transfusion therapy and administered hematologic growth factors. On June 3, 2005, the patient underwent surgical procedure to repair the abdominal wall. Two days thereafter, the postsurgical period was complicated by an episode of melena. The patient received additional treatment with packed red cells, platelets, and fresh-frozen plasma. The gastrointestinal bleeding continued until June 9, 2005, when therapy with recombinant activated FVII (Novoseven) was commenced at an initial dose of 90 mu gr/kg. The first bolus did not significantly reduce the blood loss; it was therefore administered as a successive bolus at the same dosage that was able to stop bleeding. Endoscopic examination performed the day after showed the absence of the hemorrhagic lesion in the gastric mucosa. In the subsequent days, the need for transfusion was dramatically reduced with no episode of bleeding. At the same time, the laboratory and clinical findings of marrow insufficiency disappeared. Our case report showed that the use of a global antihemorrhagic factor, such as Novoseven, can successfully control gastrointestinal bleeding even in complicated patients despite failure of traditional antihemostatic therapy
