Methods The medical records of patients with HAE admitted to Peking Union Medical College Fiospital who had received FFP infusion during 2004 and 2010 were reviewed and PubMed database iFom 1966 to the present were searched using the following key words： hereditary angioedema and fresh frozen plasma. The patient＇s age, sex, body location of HAE attacks, the dose of FFP infusion, time of beginning to improvenaent, time to complete remission, complication, C 1 inhibitor activity, and outcome were analyzed. Results A total of 13 enrolled patients （7 male and 6 female） received 16 times of FFP infusion, in- cluding 2 patients undergoing FFP infusion in Peking Union Medical College Hospital and 11 patients re- ported in the literature. The mean dosage of FFP infusion was 586±337 mL. Two cases suffered from wors- ening abdominal pain and one case experienced skin rash. Only I patient had no improvement in symptom owing to transfusion related reaction. There was a definite improvement in symptom 49± 19 minutes after beginning FFP infusion. The remission time decreased from 61.7±27.0 hours to 3.3 （2.0, 12.0） hours after FFP infusion. FFP infusion was effective for both type I and type Ⅱ HAE. Conclusion FFP seems to be safe and effective for acute attacks of HAE.展开更多

Acute kidney injury (AKI) in association with coagulopathy is an important cause of mortality. Immunomodulating effects of fresh frozen plasma (FFP) could block the nephrotoxic effects of venom;and by replenishing depleted clotting factors resulting from venom induced consumption coagulopathy could offer an additional benefit in offsetting renal injury triggered by haematological disturbances. In a non-randomised observational study carried out from 2005 to 2008 in adults at the National hospital of Sri Lanka, the mean time for resolution of coagulopathy among 42 patients treated with FFP at the inception of coagulopathy was 4.7 hours compared to 18 patients treated with isotonic Saline among whom the mean time for normalisation of coagulopathy was 6.2 hours. None of these 60 patients developed acute renal failure. A separate cohort of 32 patients with coagulopathy after hump-nosed viper bite who had not received FFP during this study period developed acute renal failure and required haemodialysis. In the absence of safe and effective antivenom for hump-nosed viper in Sri Lanka, FFP may be a therapeutic option. FFP if given early to selected patients at inception of coagulopathy may prevent AKI and serve to save lives after hump-nosed viper bites.展开更多

Potentially life threatening reactions could occur and physicians should be alerted. Here we describe a case of thrombocytopenia that was induced by transfusion of fresh frozen plasma (FFP). A 52 years old male presented to the emergency department after two episodes of hematochezia that resolved spontaneously. Since he was anticoagulated for atrial fibrillation he was given a unit of FFP to reverse a slightly elevated INR. Within 6 hours from the administration of the FFP he developed an acute decrease only in his platelet count. He was managed conservatively and his thrombocytopenia started resolving gradually. After excluding other causes the potential diagnosis was fresh frozen plasma induced thrombocytopenia. The pathophysiologic mechanism is postulated to be immune mediated by passive transfer of antibodyies from the donor to the recipient. The antibodies that are described in the literature are anti-HPA-1a and anti-CD-36. We reported the event to the American Red Cross. Interestingly a male was the donor of the plasma while in all cases in the literature the donors are females with a prior history of pregnancy. Therefore this is the first reported case of a male blood donor whose blood product caused immune mediated thrombocytopenia post transfusion.展开更多

Aggressive fluid replacement is one of the key interventions for the hemodynamic support in severe acute pancreatitis.~Although the need for fluid resuscitation in severe pancreatitis is well established, the goals and components of this treatment are still a matter of debate. We used resuscitation strategies according to early goal- directed therapy （EGDT）; we measured the effects of these volume resuscitation on clinical outcomes such as organ function and mortality. Because frozen plasma is cheaper and more easily acquired than albumin for patients, we hypothesized that fluid resuscitation with frozen plasma according to EGDT would be associated with reduced incidence of organ failure and mortality as compared with individuals resuscitated with normal crystalloid and plasma substitute volume resuscitation.展开更多

Methods: This was an observational and retrospective study comprising 67 patients (18 in group I [PCC] and 49 in group II [FFP]). The primary endpoint was the reversal of anticoagulant effect of warfarin after 2 and 24 hours of PCC or FFP administration. Comparisons between the groups were made using T-test and Q-square. Multivariate analyses were conducted using logistic regression, and the results were considered significant when p Results: The medium dose used was 27.6 UI/kg of PCC and 14.5 ml/kg of FFP. Significant differences were observed between groups I and II in the INR reversibility measurements after 2 hours (33.3% vs. 6.1%, p = 0.001) and 24 hours (38.9% vs. 12.2%, p = 0.009) as well as in the occurrence of pulmonary edema (5.6% vs. 42.9%, OR = 11.10, p = 0.04). The AUC for PCC was 0.891 (CI 95% [0.72 - 1.0]), and for FFP, it was 0.291 (CI 95% [0.09 - 0.49]). Conclusions: PCC is better than FFP treatment in reversing the warfarin intoxication after 2 and 24 hours of administration. Furthermore, PCC showed lower pulmonary edema in cardiology patients.展开更多
