Abstract

Coagulation factor VII (FVII) is a vitamin K dependent glycoprotein of the extrinsic pathway and initiates coagulation by binding to tissue factor. Activated prothrombin-complex concentrate ([APCC] FEIBA), an activated prothrombin complex concentrate that is plasma-derived, has also been demonstrated to bypass the need for FVIII or factor IX, resulting in hemostasis. Both APCC and recombinant factor VII ([rFVIIa] NovoSeven) are used for the treatment of bleeding episodes in patients with hemophilia A or B with inhibitors to Factor VIII or IX and in those with congenital Factor VII deficiency. The aim of the present study was to evaluate the clinical outcomes of APCC or rFVIIa therapy in pediatric patients (that bleeding or coagulopathy) undergoing invasive medical procedures or surgery. Twenty four patients hospitalized in pediatric clinics for intractable bleeding disorders and coagulopathies. The drugs were administered in a total of 35 episodes (25 episodes for APCC and 10 episodes for rFVIIa). Total blood count, blood biochemistry, coagulation tests and appropriate radiological assessments were performed in each patient. Survival times were calculated for each patient. The mean values of prothrombin time (PT) was 29.4±16.5 second, partial thromboplastin time (PTT) was 70.2±43.8 second and fibrinogen level was 247.8±130.2 mg/dl. The mean values after the administration of APCC or rFVIIa were 16.6±7.2 seconds, 41.2±16.0 seconds and 290.3±146.9 mg/dl, PT, PTT and fibrinogen level, respectively. The improvements in the corresponding values after therapy were statistically significant. APCC and rFVIIa can be used to prevent coagulopathy and cessation bleedings. Thus, these concentrates may be effective in reducing the incidence of thrombocytopenia and coagulopathy.

Özet

Koagulasyon faktör VII (FVII), ekstrinsik yolda vitamin K bağımlı bir glikoprotein olup, doku faktörüne bağlanması ile koagulasyonu başlatır. APCC, plazmadan elde edilmiş aktive bir protrombin kompleks konsantresi olup, FVIII ya da FIX’a gereksinim duymadan hemostazis gerçekleştirebildiği gösterilmiştir. APCC ve rFVIIa, doğumsal FVII eksikliği ya da inhibitör geliştiren FVIII ya da FIX eksikliği olan hemofili hastalarının kanama ataklarının tedavisi için kullanılır. Bu çalışmadaki amaç; kanama ya da koagulopatili pediatrik hastalarda invazif ya da cerrahi girişim için kullanılan APCC ya da rFVIIa’ın klinik sonuçlarını değerlendirmektir. Hastaneye yatırılmış ve durdurulamayan kanama ve koagulopatisi olan 24 hasta çalışmaya alındı. 35 atakta ilaçlar verildi (25 atakta APCC ve 10 atakta rFVIIa). Tam kan sayımı, kan biyokimyası, koagulasyon testleri ve uygun radyolojik değerlendirmeler her bir hasta için yapıldı. Her bir hastanın yaşam süreleri hesaplandı. Ortalama PT 29.4±16.5 saniye, PTT 70.2±43.8 saniye ve fibrinojen seviyesi 247.8±130.2 mg/dl idi. APCC ya da RFVIIa verildikten sonra ise sırasıyla 16.6±7.2 saniye, 41.2±16.0 saniye ve 290,3±146,9 mg/dl olduğu görüldü. Tedavi sonrasındaki değerlerdeki düzelme istatistiksel olarak ta anlamlı idi. APCC ve rFVIIa kanamnın durdurulmasında ya da koagulopatinin önlenmesinde kullanılabilir. Böylece de, bu konsantreler trombositopeni ve koagulopati insidansının azaltılmasında etkili olabilirler.
