SummaryThe availability of factor VIII concentrates is frequently a limitation in the management of classical hemophilia. Such concentrates are prepared from fresh or fresh-frozen plasma. A significant volume of plasma in the United States becomes “indated”, i. e., in contact with red blood cells for 24 hours at 4°, and is therefore not used to prepare factor VIII concentrates. To evaluate this possible resource, partially purified factor VIII was prepared from random samples of fresh-frozen, indated and outdated plasma. The yield of factor VIII protein and procoagulant activity from indated plasma was about the same as that from fresh-frozen plasma. The yield from outdated plasma was substantially less. After further purification, factor VIII from the three sources gave a single subunit band when reduced and analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis. These results indicate that the approximately 287,000 liters of indated plasma processed annually by the American National Red Cross (ANRC) could be used to prepare factor VIII concentrates of good quality. This resource alone could quadruple the supply of factor VIII available for therapy.

Inherited combined factor V and factor VIII deficiency (F5F8D) is autosomal recessive transmission disorder. Epistaxis, postsurgical bleeding, and menorrhagia are the most common symptoms. The risk of miscarriage and placental abruption is consequent. We report a case of successful pregnancy in a patient with F5F8D. 20-year-old woman, born of consanguineous parents, third gestate, first parity, two miscarriages, admitted for child birth of a spontaneous pregnancy estimated at 38 weeks and was diagnosed with F5F8D. At admission, patient was hemodynamically stable, with good obstetric conditions. The biologic results showed low levels of PT (52%), factor V (7%), and factor VIII (5%), and the activated partial thromboplastin time was prolonged (68,6%). Parturient was admitted in intensive care unit, maternal and fetal monitoring was performed. Fresh frozen plasma (FFP) and factor VIII concentrates were perfused at the induction of labor. Analgesia used fentanyl titration. The delivery gave birth to a newborn male, with Apgar 10/10 and 3000 g. The puerperium was simple without any important bleeding. Laboratory tests for the newborn were acceptable. Little literature is available on this subject and there are no guidelines available concerning pregnancy; we chose to prescribe a combination of factor VIII concentrate and FFP in pre-, per- and postpartum. The same protocol was successfully used in a patient before dental extraction and prostatectomy. Vaginal delivery is possible, as our case. Management by multidisciplinary team is recommended.

To the Editor.— I enjoyed reading the paper by Aronis et al,1 and would like to bring to your attention that we have also recently observed leukemia in two patients with hemophilia A and B, 10 and 1½ years of age, respectively.2 Because commercial factor VIII and IX were not used and only blood, fresh frozen plasma, and plasma were given on a few occasions, it was less likely that AIDS-like immune changes were responsible for the leukemia in our patients.

Haemophilia A is an X linked disorder characterized by bleeding manifestations due to deficiency of factor VIII. Administration of factor VIII is the mainstay of treatment in case of bleeding which is very costly. That’s why fresh frozen plasma is a very good alternative in the management of mild to moderate bleeding. Here we present a case of 50 years old male presented to us with traumatic scrotal haematoma who was newly diagnosed with Haemophilia A. As the patient was unable to bear the cost of factor VIII, we managed the patient by transfusing fresh frozen plasma. After raising his activity of factor VIII up to 30% which was adequate for soft tissue trauma, surgical exploration of scrotum was done. Both the testes were found viable. Evacuation of clot was done followed by secondary closure of the wound J Shaheed Suhrawardy Med Coll, December 2018, Vol.10(2); 118-121
