Filter by:The Patient Reported Outcomes, Burdens, and Experiences (PROBE) Study aims to develop a new global tool to enhance the direct patient-voice in health care decision-making. Government and private payers increasingly value data based on patient-centered outcomes research as part of the overall cost-benefit evaluation of high-cost care and treatment of diseases such as hemophilia. This emerging dimension of the healthcare environment presents a significant opportunity and urgent need to improve patient organizations' ability to collect and interpret relevant outcomes data. More robust patient reported data will improve advocacy efforts to build comprehensive care programs, promote home treatment and implement preventative treatment regimens thus allowing advocacy arguments to move beyond emotion and anecdote to those grounded in real-world patient experiences and evidence. With the support of the National Hemophilia Foundation, a global team of investigators will lead a patient focused research project to investigate and directly probe patient perspectives on outcomes they deem relevant to their care. Through PROBE, the investigators will develop and seek to validate the reliability, reproducibility and responsiveness of a low cost, easily administrable inventory for collecting patient self-reported outcomes, burdens and experiences in living with hemophilia. The investigators anticipate that the metrics established through PROBE will allow for comparison of patient outcomes within a country over time and cross-sectionally between countries (regionally and globally).
Designing a treatment protocol using myofascial therapy for the treatment of pain and restrictions on mobility in patients with hemophilic arthropathy of the knee and ankle. Pilot with a small number of patients for assessment the effectiveness and safety of the treatment protocol created. Randomized clinical trial to assess the effectiveness of treatment with myofascial therapy in patients with hemophilia. Describe the differences in terms of the dependent variables (range of motion, pain and flexibility) in patients with hemophilia who have carried out the treatment. Report the relationship between the clinical characteristics of patients and the results obtained after the treatment period.
The purpose of this research study is to see if factor levels and inhibitor levels in Hemophilia A and B subjects are accurate when they are drawn from a central venous line (CVL) instead of from a peripheral stick.
Background Hemophilia is a sex-linked genetic disorders. When the joint or the muscles is bleeding, it may cause haemarthrosis, synovium, cartilage tissue thickening, joint activity (Range of Motion) decreasing and other musculoskeletal and related disorder. Patients will produce pain in the action, compensatory action occurs, thus causing recurrent of bleeding, and joint damage. There is high rate of ankle joint bleeding in hemophilia. The ankle articular joint disease will affect lower limbs activities, and the functional activities will impaired. Review studies, in addition to physical therapy, Kinesio taping is a common intervention to improve other subjects' static balance, proprioception, functional ankle stability, correct poor posture. The main intervention of this study is physical therapy and Kinesio taping, expect to improve the stability and muscular strength of lower extremities, and balance, correcting gait and lower extremity functional activities of subjects with hemophilia.
One of the major shortcomings in studying bone disease in hemophilia is the lack of fracture outcome data demonstrating the clinical significance of decreased BMD and altered bone biomarkers in the hemophilia population. This study demonstrates that PwH have an increased risk of fracture compared to the general population and that the issue of bone health will increase in importance as the PwH population ages.
The purpose of this study is to find out if gross motor skills of children and young adults with bleeding disorders are different from those without bleeding disorders. The investigators will use the standardized motor test the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2 tm). The second purpose is to establish if history of joint disease secondary to bleeding affects gross motor skills. 1. Participants and setting: Subjects will include up to 100 male youth and young adults, ages 4 to 21, recruited from the patient population of the Hemophilia Treatment Center at OHSU. A mailing that describes the study may be sent to all potential subjects who receive care through the Hemophilia Treatment Center at OHSU. Data collection will occur at either clinic visits or in the home. Information, including history of change in joint structure and synovium, from existing bleeding disorder repositories at OHSU will also be used. 2. Design and Procedures: Research will be done using a prospective, cross-sectional study design to examine any relationship between a diagnosis of bleeding disorder and gross motor development. The gross motor ability of children and young adults with bleeding disorders who meet the inclusion criteria will be compared to sex-specific normative data from a standardized motor test. Information about age, type of hemophilia, presence of an inhibitor, type of management used, body composition, range of motion, and hand strength will also be collected through direct measurement and chart review. The information collected will be entered into a repository. A subject may choose to opt out of the repository while still participating in the research study. In addition, information from a current hemophilia repository will be compared to gross motor ability scores to determine if joint disease is related to skill level in this group of people. 3. Proposed analyses: Two-tailed t tests and logistic regression will be used to determine if there are any significant differences.
Analyze and evaluate the skeletal muscle of patients affected with hemophilia in the Region of Murcia. - Describe the periarticular muscular deficit of the lower limbs, depending on the degree of injury: acute and chronic, or subacute. - Identify the range of motion of joints with higher prevalence of hemophilic arthropathy. - Detect the biomechanical changes of the lower limbs and their impact on gait in patients with hemophilia. - Assess the factors that influence the perception of illness and quality of life of patients with hemophilia.
Trial to assess the bilateral deficit phenomenon during dynamic plantar flexion task in patients with haemophilic arthropathy Describe the differences in terms of the physical variables (muscular strength, range of motion and proprioception) in patients with hemophilia who have conducted a home treatment with a digital tool. Bookmark the relationship between clinical history of joint bleeds and clinical manifestations in standing and walking.
A multi centre two year long term escalating dose tertiary prophylaxis study on the efficacy and cost saving of individualized low dose prophylaxis regimens for boys with severe hemophilia A in China staring with a low dose regimen in step I, an escalated low dose regimen in step II and a tailored dose regimen based on individual PK profiles in step III. The dose escalation criteria are adjusted according to patterns and frequencies of joint bleeding and assessed in each subject every 3 months. Efficacy of the 3 different dose regimens are measured by the Annualized Joint Bleeding rate (AJBR) as a primary end point and the Hemophilia Joint Health Score (HJHS ) and QoL scores (CHO-KLAT and PedsQoL) , image studies of target joints by Ultrasound, X-ray and MRI examinations, consumption of factor VIII and inhibitor rates as secondary end points.
Hemophilia is caused by a single-gene defect resulting in familial bleeding disorder. Small increase in gene products could transform a severe form of hemophilia into a mild one. Stem cells from extrahepatic sources are being considered for clinical applications in liver cell therapy as they possess high in vitro culture potential and could be used in transplant procedures. We studied the differentiation of bone marrow hematopoietic stem cells (BM-HSCs) from hemophilia patients' relatives into factor 8 (FVIII)-producing hepatocyte-like cells aiming to expand patients' donor options for partial replacement of mutant liver cells by healthy cells in hemophilia A patients which could manage the severity of the bleeding disorder. BM-HSCs from hemophilic families will be cultured in short-liquid hepatic induction medium. Appearance of hepatic phenotype will be evaluated by alpha-fetoprotein expression using immunocytochemistry. Functional evaluation of transdifferentiation will be done through detection of albumin synthesis using microalbumin assay kit, factor VIII activity by one-stage clotting assay and expression of FVIII messenger RNA( mRNA) by reverse transcription ( RT-PCR). Inducing the differentiation of BM-HSCs by in-vitro manipulation may become a valuable tool to provide a cell source for hepatocyte transplant procedures for treatment of hemophilia patients.
