Objective: The objective of this study was to analyse the reversibility of the anticoagulant effect of warfarin by comparing prothrombin complex concentrate (PCC) versus frozen fresh plasma (FFP) in cardiology patients with serious warfarin intoxication. 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

AIM:To investigate whether fresh frozen plasma (FFP) transfusion affects outcomes following hepatic resection for hepatocellular carcinoma (HCC) in terms of liver function,postoperative complications and cancer prognosis.METHODS:We retrospectively compared the incidence of postoperative complications between 204 patients who underwent hepatectomy for HCC with routine FFP transfusion in an early period (1983-1993,Group A) and 293 with necessity for FFP transfusion during a later period (1998-2006,Group B),and also between two subgroups of Group B [22 patients with FFP transfusion (Group B1) and 275 patients without FFP transfusion (Group B2)].Additionally,only in limited patients in Group B1 and Group B2 with intraoperative blood loss≥ 2000 mL (Group B1 ≥ 2000 mL and Group B2 ≥ 2000 mL),postoperative complications,liver function tests,and cancer prognosis were compared.RESULTS:No mortality was registered in Group B,compared to 8 patients (3.9%) of Group A.The incidence of morbidity in Group B2 [23.2% (64/275)] was not significantly different from Group B1 [40.9% (9/22)] and Group A [27.0% (55/204)].The incidence of complications and postoperative liver function tests were comparable between Group B1 ≥ 2000 mL vs Group B2 ≥ 2000 mL.Postoperative prognosis did not correlate with administration of FFP,but with tumor-related factors.CONCLUSION:The outcome of hepatectomy for HCC is not influenced by FFP transfusion.We suggest FFP transfusion be abandoned in patients who undergo hepatectomy for HCC. 展开更多

Objective To determine the safety and efficacy of fresh frozen plasma (FFP) iniusion for the treat- ment of hereditary angioedema (FIAE). 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

Objectives: The aim of this study was to investigate the effectiveness of dietary intervention with apricots, pomegranate juice or lactic acid fermented sobya on improving the plasma levels of lipid profile parameters and total plasma homocysteine (tHcy) among healthy adults. Design of the study: Thirty-five men and women (28.9 ± 3.0 years) with mean body mass index of 23.5 ± 1.2 kg/m2 were randomly assigned to a dietary intervention study. During the pre-feeding study records of 24-hour food intake, anthropometric measurements and blood sampling were collected for biochemical investigations. Thereafter the volunteers were divided into five groups: a control group (C);the other four groups received daily one of the following supplements: 200 g of deep yellow apricots (Prunus armeniaca) (AF);250 g pomegranate (Punica granatum) juice (PJ);mixture of 100 g (PJ) and 150 g of fermented sobya (FS), (PJ-FS) or 165 g (FS). After completing the three-week dietary intervention, blood samples were collected and blood indices were again evaluated. Biochemical analysis of total lipids (TL), total glycerides (TG), total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) and tHcy were completed. The low density lipoprotein-cholesterol level and three indices of risk factors were calculated using the appropriate equations. Results: Three-week dietary intervention improved the levels of lipid profile parameters TG, TC, HDL-C and LDL-C as compared to the respective baseline levels and the response of the control group that did not receive any supplement. Consuming (PJ-FS) had a synergistic beneficially added value on some of the above mentioned lipid profile parameters. The mean plasma tHcy concentrations;a marker for occlusive vascular disease was reduced significantly following the three week consumption of (PJ) or (FS), compared with the respective pre-feeding levels. Conclusion: Pomegranate juice (PJ) or lactic acid fermented sobya (FS) or mixture of both are potential natural agents in lowering the plasma levels of lipid profile parameters and tHcy among apparently healthy young women and men, without dyslipidemic symptoms. 展开更多
