Validation of Questionnaires HAL and HEP
HaemophiliaSpanish Validation of HAL and HEP questionnaire by double translation (English-Spanish-English), with a pilotage pediatric patients with hemophilia and adults and parents of children with hemophilia. The final validity will be obtained with a sample of 60-100 patients with hemophilia
Quality of Life in Adult Patients With Severe Haemophilia in Turkey
HaemophiliaThe primary aim of this study is to evaluate the overall quality of life in adult patients with severe haemophilia (an inherited bleeding disorder affecting mainly men) in Turkey and to assess the impact of certain disease and drug related factors (treatment modality, presence of viral disease, inhibitor, etc.) on the quality of life.
Clinical and Health-related Outcome of rFVIIIFc Prophylaxis
Hemophilia ACurrent standard therapy for patients with haemophilia (PwH) in the prevention of bleeding episodes is a prophylactic intravenous treatment with recombinant coagulation factor (F) VIII (Haemophilia A) or rather FIX (Haemophilia B) two to three times weekly. With the development of recombinant factor VIII Fc fusion protein (rFVIIIFc) the conventional routine prophylaxis regime is complemented by an extended half-life (EHL) factor replacement prophylaxis with the potential of improved bleed prevention and reduced injection frequency at similar factor consumption. Aim of this longitudinal multicentre study is to evaluate the influence of an EHL factor replacement regime with rFVIIIFc on haemophilic specific parameters (annual bleeding rate, bleeding localisation), joint status, pain, functional parameters, treatment adherence and health-related quality of life in PwH A.
Ex Vivo Laboratory Assays Application for Therapy Tailoring in Patients With Severe Bleeding Disorders...
Severe HemophiliaTherapy of patients with severe hemophilia (including hemophilia with inhibitors) and other severe bleeding disorders could be monitored and guided based upon special clotting assays , eg thrombin generation and thromboelastography. In this study blood sampled from patients with bleeding disorders will be evaluated applying ex- vivo spiking assays with various coagulation concentrates to potentially address the feasibility of replacement /bypass agents/ combined therapy for future bleeding episodes. Patients that will be further treated by any regimen potentially suggested (as standard care- not within trial) will be thereafter followed , including repeated lab studies to assess the impact of therapy upon hemostasis.
Effectiveness of the uPatient Platform in Prophylactic Treatment in Hemophilia
HaemophiliaResearch project whose main objective is to evaluate the use of a technology platform (uPatient) to register the prophylactic treatment of patients with hemophilia treated in different Hematology and Hemotherapy services of several hospitals in Spain.
A Study of Factor Inhibitors in Adult Patients With Hemophilia and Von Willebrand's Disease in Upper...
HemophiliaVon Willebrand Diseases1 moreHemophilia A and B are bleeding disorders caused by deficiency of factor VIII and IX, respectively. The deficiency of one of these coagulation factors is due to a mutation on the X chromosome. Accordingly replacement of the deficient factor is currently the main treatment for these disorders. The most disappointing complication of replacement therapy in hemophilia is the development of inhibitors. Unlike haemophilia , inhibitor development in patients with V Willebrand's Disease (VWD) is a rare complication of treatment. Studies on inhibitors whether on hemophilia or VWD are limited in our region. This study aims to To estimate the frequency of factor inhibitors in hemophilia and VWD patients in our region. To investigate modifiable risk factors associated with development of inhibitors in both diseases. To correlate the level of inhibitor with the clinical presentation of the patients. To assess influence of factor inhibitors on quality of life in patients who developed factor inhibitors in both diseases.
Osteoporosis and Haemophilia
OsteoporosisHaemophilia1 moreThe aim of this study is to evaluate the prevalence of osteoporosis in adult patients with haemophilia.
Development of a Specific Measure for Assessing Adherence in Adult Patients With Hemophilia.
HaemophiliaResearch project for the development, construction and validation of a questionnaire of adherence to treatment in adult patients with hemophilia. It aims to build a scale according to five relevant dimensions of adherence to treatment: 1) physician-patient relationship, 2) knowledge of the disease, 3) previous bleeding problems, 4) knowledge of future consequences and difficulties, and 5) benefits of treatment.
Turkish Acquired Haemophilia Registry
Acquired HaemophiliaTurkish Acquired Haemophilia Registry is a database in which information about clinical features and therapeutic management of acquired haemophilia is collected in Turkey.This is a multicentre, retrospective and prospective registry of subjects diagnosed and/or treated for acquired haemophilia. Patients will be registered and the response to different therapies, details of each bleeding episode and the outcome of haemostatic and immunosuppressive therapy (IST) will be recorded. Any male or female subject diagnosed with inhibitors to FVIII or other factors and treated for acquired haemophilia can be entered on the registry. Patients will be treated according to local practice. No additional tests or procedures are required by the registry. The retrospective period will not be time-limited and data will be collected from those recorded in the hospital notes. The prospective period will begin in September 1.2011, and will last for two years.
