Vein thrombosis). This indicates that the rate of thrombotic complications depends on disease and patient selection. Because of this association PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/25957400 with serious adverse effects and the substantial cost, off-label use of rFVIIa may only be justified in cases with at least some evidence of benefit and otherwise untreatable life-threatening bleeding. This is particularly true for diseases with unknown efficacy of rFVIIa. In a recent systematic review on the clinical use of rFVIIa from a total of 124 case series and 176 case reports [3], treatment failures were only rarely reported. This may indicate outstanding efficacy of rFVIIa, as an “universal haemostatic agent”. Another likely explanation is publication bias. Therefore, we would like to report a patient with life-threatening bleeding that failed to respond to repeated doses of rFVIIa.Bleeding started at day +18 after transplantation with bloody diarrhea, which was treated with multiple transfusions of fresh frozen plasma, platelet, and red blood cell concentrates. Endoscopy revealed diffuse intestinal mucosal bleeding, from the stomach to the rectum; biopsy revealed high-grade acute GvHD. Bloody diarrhea continued despite all efforts, which included frequent transfusions of platelet and red blood cell concentrates (Figure), high-dose prednisolone, broad antibiotic and antiviral coverage, and daily tranexamic acid. Fresh frozen plasma had been administered repeatedly earlier than day +24. After admission to the ICU (day +20) estimated volume losses were replaced by albumin, crystalloids and red blood cell concentrates as long as global coagulation tests were in the high normal range (Figure). All routine coagulation tests (prothrombin time, activated partial thromboplastin time and fibrinogen, were performed at least thrice daily. Fibrinogen never fell below 200 mg/dL (reference > 140), prothrombin time (reference > 70 , Figure) and aPTT always were in plain normal range, except in the terminal 24 hours. Therefore, we considered fibrinogen concentrates not to be useful. We preferred fresh frozen plasma over prothrombin complex concentrates to replace losses. Prothrombin complex concentrates were not used in our patient. Thrombopenia was treated by platelet concentrate transfusion; additional desmopressin was not used. Renal function remained normal. Pulmonary bilateral infiltrates and need of mechanical ventilation were unchanged. Body temperature was get POR-8 fluctuating between 37.0 to 39.2 elsius, systolic blood pressure between 100 and 170 mmHg with intermittent vasopressor support. Heart rate was between 110 and 160 /min. After a period of apparent overall stability (day +24?7) profuse anal bleeding with declining hemoglobin and blood pressure prompted massive red blood cell transfusions (Figure) and use of vasopressors. Blood coagulation tests remained normal. rFVIIa was started at day +29 with desperation at the unremitting gastrointestinal bleeding, as compassionate use (Figure). Boluses of 90?20 /kg were given every 4? hours. After nine doses, rectal bleeding rate decreased, and PT somewhat shortened ( increase), albeit always in the normal range (Figure). rFVIIa was discontinued. Less than 24 hours later, on day +33, massive transrectal bleeding recurred. Hemoglobin fell to 5 g/dL and hypotension required a sharp increase of vasopressor doses. Recombinant FVIIa was started again. Repeat endoscopy confirmed diffuse bleeding from severely lacerated mucosa of stomach and duodenum.CaseWe.
