Objective—Ischemic heart disease mortality is lower in hemophilia patients than in the general male population. As coagulation plays a role in the inflammatory pathways involved in atherogenesis, we investigated whether the clotting factor deficiency protects hemophilia patients from developing atherosclerosis. Methods and Results—Coronary artery calcification, measured with multidetector-row c...

Electroconvulsive therapy (ECT) is used for medication-resistant and life-threatening mental disorders, and therefore it occupies an important position in psychiatric treatment. ECT reportedly increases intracranial pressure and is suspected of increasing the risk of intracranial hemorrhage, especially in patients with hemorrhagic diseases such as hemophilia. A decrease in or loss of blood coag...

The presence of antibodies (Abs) in hemophilia A patients can potentially influence the therapeutic qualities of factor VIII (fVIII) administration. Much work has been focused on the presence of inhibitory antibodies, whereas the quantitation of noninhibitory anti-fVIII antibodies has been largely undetermined. Our objective was to develop a sensitive and specific fluorescencebased immunoassay ...

BACKGROUND Gene therapy could prevent bleeding in patients with hemophilia A, but might induce antibodies that block factor VIII (FVIII) function. OBJECTIVES To test the efficacy of gene therapy in the newborn period for preventing a response to human FVIII (hFVIII) because of immaturity of the immune system. METHODS Varying doses of a retroviral vector (RV) expressing a B domain-deleted hF...

Hemophilia A and B are severe Xlinked inherited bleeding disorders caused by deficiency of blood coagulation factors (F) VIII and FIX, respectively. Currently, hemophilia is treated with protein replacement therapy using either plasma-derived or recombinant coagulation factors. Although replacement therapy is extremely effective and has significantly enhanced the quality and life expectancy of ...

We tested serum samples from 50 hemophiliacs from Sevilla, Spain, for antibody to HTLV-III by indirect membrane immunofluorescence (IMI) and radioimmunoprecipitation with SDS polyacrylamide gel electrophoresis (RIP-SDS/PAGE). All had received commercial clotting factors from the United States with the exception of one hemophiliac who had never been transfused. Thirty-four (68%) reacted with HTL...

INTRODUCTION The incidence of subclinical hemophilic arthritis is low, with this case reports and literature review, we hope clinicians could pay more attention to the diagnosis of subclinical hemophilic arthritis and prevent the misdiagnosis and mistreatment. CASE PRESENTATION We analyzed the imaging feature, and therapy of a subclinical hemophilia case with hip lesion by reporting its clini...

Reports of hemophilia-associated acquired immunodeficiency syndrome (AIDS) in the United States were first published in July 1982 (1). Since then, the number of U.S. patients with underlying coagulation disorders who develop AIDS has increased each year. In 1981, one U.S. case was reported; in 1982, eight; in 1983, 14; and, as of October 15, 29 cases have been reported in 1984, for a total of 5...

Immune responses to coagulation factors VIII (FVIII) and IX (FIX) represent primary obstacles to hemophilia treatment. Previously, we showed that hematopoietic stem cell (HSC) retroviral gene therapy induces immune nonresponsiveness to FVIII in both naive and preimmunized murine hemophilia A settings. Liver-directed adeno-associated viral (AAV)-FIX vector gene transfer achieved similar results ...

During the period from 1978 to 1983, 92 pregnancies have been evaluated by fetoscopy for the prenatal diagnosis of hemophilia A. Satisfactory fetal plasma samples were obtained in 80 instances and the diagnosis--or exclusion--of hemophilia was made by immunoradiometric assay of the factor VIII coagulant protein (VIII:CAg). The accuracy of the diagnosis established by fetoscopy has been verified...
