Continuous infusion of rFVIIa during surgery in a FVII-deficient patient: a case report from Japan

Continuous infusion of recombinant activated factor VII: a review of data in congenital hemophilia with inhibitors and congenital factor VII deficiency

Introduction

Continuous infusion (CI) of clotting factors as a replacement therapy for perioperative hemostatic protection has been performed for many years, including with factors VIII and IX and recombinant activated factor VII (rFVIIa). This approach provides steady factor levels without requiring frequent administration of bolus doses.

Aim

To review safety, efficacy, and dosing data regarding CI of rFVIIa for hemostatic management of patients with congenital hemophilia with inhibitors (CHwI) or congenital factor VII deficiency (C7D).

Materials and methods

A literature review identified instances of CI of rFVIIa in patients with CHwI or C7D undergoing surgery or experiencing bleeding episodes. Data regarding safety, efficacy, and dosing were extracted.

Results

The safety and efficacy of 50 mcg/kg/h CI of rFVIIa following a 90 mcg/kg bolus injection, vs a standard bolus injection regimen, was reported for 24 patients with CHwI undergoing elective surgery in an open-label, randomized, Phase III trial. Efficacy was similar between CI and bolus injection groups at all postoperative time points assessed. Additionally, a postmarketing surveillance study reported effective (80%) and partially effective (20%) CI of rFVIIa in a Japanese cohort of ten patients with CHwI who underwent 15 surgical procedures. Finally, the safety and dosing of rFVIIa CI in 193 and 26 patients with CHwI and C7D, respectively, were reported in 11 prospective studies, 10 retrospective studies, and 30 case reports. No unexpected safety findings were reported.

Conclusion

rFVIIa CI has been performed safely and effectively in patients with CHwI and C7D undergoing surgery and during bleeding episodes in patients with CHwI.

Continuous infusion of human prothrombin complex in a patient with congenital factor VII deficiency undergoing laparoscopic cholecystectomy: A case report from China

•

We describe a case of successful replacement treatment with PPSB, without episodes of bleeding and thrombosis.

•

This is the first report of the patient with congenital FVII deficiency undergoing laparoscopic cholecystectomy with repeated administration of PPSB.

•

PPSB is made in China, it also provides direction for the use of other similar drugs to solve the same problem.

Introduction

Factor VII deficiency is a rare cause of haemorrhagic syndrome. PRESENTATION OF CASE: The authors describe a case of a 48 years old patient with congenital factor VII deficiency suffering abdominal discomfort diagnosed as gallstone, that successfully underwent laparoscopic cholecystectomy with continuous infusion of Human Prothrombin Complex(PPSB) around the procedure.

Conclusion

The usage of PPSB solved the clotting problems enabling the surgical procedure, without risks for the patient.
