Filter by:Primary prophylaxis in severe hemophiliacs is defined that prophylaxis therapy starts before 2 years of age and prior to any clinically evident joint bleeding or after first joint bleeding and prior to the onset of joint damage irrespective of age, joints can be kept normal or very mildly damaged till teenage or adulthood. Primary prophylaxis has been proved to be more beneficial and cause less damage to joint than "on-demand" therapy. Primary prophylaxis is also known to be able to decrease the occurrence of factor VIII inhibitor and is the most advanced and useful, cost-effective therapy for hemophilia care. However, it requires 2 to 3 injections of factor VIII or IX of 20-50 IU/Kg doses every week, it costs a lot of expenses. In the year 2013, we tried hard to discuss with Bureau of National Health Insurance (BNHI) and have meeting a couple of time, eventually a guideline of an intermediate-dose prophylaxis for severe hemophilia was established and a consensus was reached that this prophylactic treatment will be cost effective without increased burden of total budget. This guideline was finally approved by BNHI and will be implemented from July 1st, 2014. In oder to evaluate the efficacy of prophylaxis treatment, patients will be arranged to come back to each hemophilia center at least once a year to have investigation of doses and annual consumption of clotting factors, frequencies and causes of bleedings, especially joint bleedings, joint outcome by studies of hemophilia joint health score (HJHS), hemophilia actives list and health-related quality of life. These results will be collected and compared between intermediate-dose prophylaxis group of patients and on demand treatment group of patients. The life span of hemophiliacs has been improved remarkably in recent years due to sufficient and adequate treatments, especially prophylaxis treatment, therefore comorbidities in the hemophilic population, e.g. hypertension, diabetes, hyperlipidemia and cancer, etc, have been found with prevalences close to those in non-hemophilic population. It is worth that the prevalence of these comorbidity will also be investigated. In addition, basic data of the patients including age, sex, severity, the development of inhibitor and viral infection etc will also be collected for analysis.
The purpose of this study is to evaluate the efficacy and safety of BAX 802 in males with congenital hemophilia A (CHA) with inhibitors who are undergoing major or minor elective surgical, dental, or other invasive procedures.
Participants will be assigned to A or B groups with a scale of 1:1 based on a prospectively randomized treatment-sequence assignment, i.e. infuse SCT800 followed by Xyntha (group A), or the alternate sequence (group B). All participants who completed the SCT800HA1 study will enter the efficacy and safety study (Protocol No.: SCT800HA3).
The purpose of this study is to evaluate the relative effectiveness of two psychological interventions, cognitive-behavioral therapy (CBT) and hypnosis (Hyp), in preventing and managing pain, regulating emotional state and improving quality of life in Portuguese PWH.
The purpose of this study is to implement a national survey to collect information regarding Portuguese people with haemophilia (PWH) on socio-demographic, clinical and psychosocial factors.
Severe haemophilia is a rare disease characterized by spontaneous bleedings from early childhood, which may lead to various complications especially in joints. Due to advances in medical care and more specifically in the development of prophylactic strategies by the application of clotting factor concentrates, life expectancy of persons with severe haemophilia has significantly increased over the last decades. This progress requires a long-term follow-up, including into adulthood. The adherence to a regular clinical follow-up and to a prophylactic treatment then depends on how successful patients' transition from childhood to adulthood has been as this process involves a transfer of responsibility from parents to patients concerning the management of their health. Beyond the issue of patients' adherence, a suboptimal transition may also impair quality of life and the entry into adulthood, especially at the social, emotional and professional levels. Only a few studies have been conducted to identify the specific needs and difficulties young persons with severe haemophilia experience during their transition from childhood to adulthood, and none of these studies has been carried out in France where the features of the health care system are very specific. Therefore, this study aims to address the issue of transition into adulthood among young persons with severe haemophilia in France. This study will focus not only on the facilitators and barriers of the access to health care but also, from a more global perspective, on all the specific concerns and difficulties they may experience as they grow into adulthood which may impair their long-term health related quality of life as well as their personal empowerment. This study will also allow to identify some of the socio- cognitive, emotional, and familial determinants of a good transition into adulthood.
Physical activity is lower in patients with haemophilia than in their healthy peers. Nevertheless, exercize is recommended for those patients and supported by evidence. Until 2013, scientific and medical evidence to encourage physical activity for patients with haemophilia were listed to increase their locomotor function, their metabolic status, their fitness level and their well-being. In 2013, an original publication by Groen et al. suggested that physical activity could also interact with the specific and biological disturbance of the disease. We propose to consider that regular endurance exercize prescription should be encouraged in patients with haemophilia not only for a healthier lifestyle but also because it could positively alter the specific biological blood disturbance seen in haemophilia. Nevertheless, before planning a well powered intervention trial we need to determine the acceptability of regular exercize and the expected value of factor Factor VIII, von Willebrand factor and von Willebrand propeptide after an endurance training program.
This is a randomized, global, multicenter, open-label, Phase 3 clinical study in participants with severe hemophilia A without inhibitors against Factor VIII (FVIII) who are 12 years or older. The study evaluates two prophylactic emicizumab regimens versus no prophylaxis in this population with emphasis on efficacy, safety, and pharmacokinetics.
The primary objective of this study is to investigate weekly prophylaxis dosing regimens used in standard clinical practice. In addition the study will capture reported bleed rate, pattern of change in KOVALTRY prophylaxis dose & dosing frequency, reason for choice of treatment regimen, FVIII product switch pattern, patient treatment satisfaction and adherence, KOVALTRY pharmacokinetic data (if performed), KOVALTRY consumption, as well as safety data.
Although arthropathy is a serious problem in patients with hemophilia due to the associated morbidity and incapacity, to the best of the investigators knowledge, no studies have looked at the effect of educational physiotherapy for its clinical improvement. This contribution presents the results of educational physiotherapy program applied for 15 weeks with home exercises - in patients with hemophilic arthropathy. After treatment, experimental group showed improved a significant reduction of pain, and best quality of life al illness behaviour. During treatment no patient showed elbow haemarthrosis, which underlines the safety of this physiotherapy program.
