Filter by:This study will examine viral dynamic responses in subjects with chronic hepatitis C and hemophilia when treated with pegylated interferon + ribavirin and telaprevir.
Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
The purpose of this study is to test the external validity of the systemic ultrasound protocol for data acquisition and interpretation, in order to diagnose soft tissue and osteochondral abnormalities in hemophilic children.
To collect and analyze data on female carriers of severe and moderate hemophilia A and B.
The original Joint Outcome Study (JOS) enrolled 65 boys with hemophilia from 16 sites nationally. The subjects were randomized to one of two arms (prophylaxis or an enhanced episode-based treatment)and were followed prospectively until the age of six. At the age of six, the proportion of children on each treatment arm who developed bone or cartilage damage as determined by X-Ray or MRI was assessed. In addition, the function and structure of the index joints (defined as knees, ankles, and elbows)were evaluated using a physical assessment scale specially designed for preschool children. The specific aim of the Joint Outcome Study Continuation (JOSC) is to extend observations of the children participating in the original JOS until the subjects reach the age of 18 years in order to determine the natural history of joint development in hemophilia and the impact of primary or secondary prophylaxis on the prevention, limitation, or reversal of hemophilic arthropathy. In addition, plasma and DNA will be collected and banked yearly for current and future studies of biomarkers and predictors of hemophilia outcomes.
This study will analyze survival and outcome of patients with severe haemophilia who undergo liver transplantation in Spain
The purpose of this study is to collect reference data in patients with haemophilia. The study will also collect and store blood samples for potential future exploratory research in the disease area.
Hemophilic patients are a known high risk groups for acquiring the hepatitis C. The surveillance data from Ministry Of Health in IR.Iran had shown that 60% of them are infected with HCV infection. We are trying the PEGASYS plus Ribavirin in Hemophilic patients with HCV.
The high percentage of failure using available non-surgical options to treat menorrhagia in women with bleeding disorders shows a continuing need for innovative treatments. This has led to development of this protocol in order to make available tranexamic acid as a potentially effective menorrhagia therapy option in women with an underlying bleeding disorder. We anticipate that Tranexamic Acid may be a beneficial choice for controlling menorrhagia in bleeding disorder patients.
Congenital deficiency of Factor XIII is a rare but potentially life threatening disorder. It is inherited in an autosomal recessive fashion. Infusion of Factor XIII has proved to be useful for prevention and treatment of bleeding episodes, especially of spontaneous intracranial bleedings. In this study, Fibrogammin P will be given to patients with congenital Factor XIII deficiency and congenital/acquired FXIII deficiency to prevent bleeding and to treat established bleeding episodes. For Factor XIII prophylaxis to prevent hemorrhages, the dosage will depend on the weight of the subject. The frequency of Factor XIII administration will be determined by the factor's circulating half-life. During the first month only, a Factor XIII pharmacokinetic study will be determined over a 4-week period. Safety data will include accrual of information on viral safety, liver function, complete blood counts and adverse events. Historical data concerning spontaneous bleeds will be collected whenever possible two years prior to treatment with Fibrogammin P.
