    Notes: Summary.  Participants in an international conference on prophylactic therapy for severe haemophilia developed a consensus summary of the findings and conclusions of the conference. In the consensus, participants agreed upon revised definitions for primary and secondary prophylaxis and also made recommendations concerning the need for an international system of pharmacovigilance. Considerations on starting prophylaxis, monitoring outcomes, and individualizing treatment regimens were discussed. Several research questions were identified as needing further investigation, including when to start and when to stop prophylaxis, optimal dosing and dose interval, and methods for assessment of long-term treatment effects. Such studies should include carefully defined cohorts, validated orthopaedic and quality-of-life assessment instruments, and cost-benefit analyses.

    Notes: Summary.  The provision of health care to patients with haemophilia through replacement of the deficient coagulation factor is the result of a complex interaction between patients, physicians and policy makers, each carrying their individual sets of preferences. Preferences of patients, physicians and pharmacists towards perceived viral safety, risk of inhibitor development, infusion frequency during prophylaxis, pharmaceutical dosage form, distribution modes and price were evaluated by conjoint analysis, using a discrete choice experiment. Overall 178 patients’, 69 physicians and 58 pharmacists completed the study. Patients, physicians and pharmacists displayed preferences: (i) similar in direction and strength for risk of inhibitors and frequency of prophylaxis, (ii) similar in direction, but not in strength for perceived viral safety and price, with patients showing lower strength compared with physicians and pharmacists, and (iii) dissimilar in direction and/or strength for: (i) dosage form, which tested important only for pharmacists and (ii) distribution mode, which tested important for patients and physicians only. Our study provides evidence of the differences between different stakeholders in the preferences towards haemophilia replacement therapy, indicating that different opinions should be taken into account when planning optimal care.

    Notes: Summary.  The Italian Association of Haemophilia Centres reviewed and finally approved in November 2004 the new Italian Guidelines for the diagnosis and treatment of patients with clotting factor inhibitors. The recommendations have been based on the identification of levels of clinical evidence derived from the systematic review carried out in 2003 by the School of Health and Related Research, the University of Sheffield, UK, and further integrated by clinical studies published from 2003 to 2004. The Italian guidelines consist of six major domains concerning inhibitor definition, epidemiology, risk factors, diagnosis, inhibitor eradication, management of bleeding episodes, in patients with congenital and acquired coagulation disorders, with 121 statements, 59 synthesis and 54 recommendations. We report here recommendations and open issues concerning the diagnosis and monitoring of inhibitors, inhibitor eradication and the management of bleeding in patients with haemophilia A and B.

    Notes: Summary.  The benefits of prophylactic infusion of clotting factor in haemophilia A and B in delaying the onset of arthropathy are supported by retrospective data, but the possibility of selection bias and confounding factors cannot be ruled out by such studies. Many issues that have only been studied retrospectively require definitive data, including the optimal dose and infusion intervals, as well as when to start prophylaxis and when to stop it. Issues of cost-effectiveness of prophylaxis, quality of life and treatment satisfaction of patients on prophylaxis and their families also require prospective data. To advance the evidence-based approach in haemophilia treatment, ESPRIT (Evaluation Study on Prophylaxis: a Randomized Italian Trial), currently underway, is a prospective randomized 10-year study that will compare the efficacy and safety of prophylaxis and on-demand regimens in preventing joint deterioration and in reducing the number of bleeds in patients with severe haemophilia A.

    Notes: Summary.  Prenatal diagnosis (PND) is an important issue in the comprehensive care of haemophiliacs. As a consequence of technological progress made in the field of PND, the early detection of an affected fetus provides the expectant couple with a chance to terminate pregnancy. This study was undertaken to assess the attitudes of two different haemophilic populations in Iran and Italy towards PND and termination of pregnancy. This study series included 59 Iranians (38 haemophilia A patients and 21 mothers) and 50 Italians (27 haemophilia A patients, 16 mothers and seven fathers). All the 109 participants received a questionnaire including demographic characteristics and evaluating the psychological effects stemming from PND and termination of pregnancy. Approximately 84.7% of the Iranians and 35.4% of the Italians were not familiar with the possibilities afforded by PND for haemophilia (P 〈 0.001). Termination of pregnancy appeared to be accepted by 58.2% of the Iranian and 16.7% of the Italian participants (P 〈 0.001). The greater rate of acceptability of abortion in Iranians may be due to differences in the quality of patient care in the two countries.

    Notes: We conducted a multicentre, cross- sectional study of 1042 haemophilia subjects across Europe to compare various health outcomes associated with on-demand vs. prophylactic factor-substitution therapy. Demographic, medical history, and healthcare resource utilization data were analysed along with the number of bleeding events over the past 6 months. Treatment-cost data were also examined to provide preliminary information for future economic studies. A logistic regression analysis, controlling for other statistically significant covariates, showed that patients treated on demand were 3.4 times more likely to have had a joint bleed over the previous 6 months than those treated with prophylaxis. Multiple regression analyses further confirmed these findings, because on-demand subjects had, on average, 5.15 more joint bleeds over the reporting period than patients treated with prophylaxis. Notably, these findings were even more dramatic for younger haemophilia patients when our study sample was stratified by age. Due to the high cost of factor replacement, healthcare costs were significantly higher for subjects treated prophylactically. While hospital costs for prophylaxis subjects were, on average, lower, statistically significant cost savings for prophylactic subjects were not noted. These results suggest that clinicians and health policy decision-makers should consider the advantages of prophylactic therapy for haemophilia patients in formulating treatment protocols and allocating health resources.

    Notes: The European Study on the Clinical Outcomes and Resource Utilization associated with Haemophilia Care was designed to compare various health outcomes associated with on-demand and prophylactic factor substitution methods in European haemophilia patients. While the primary objective of this research is to conduct an economic analysis, an important component of this study is to evaluate quality-of-life differences that may exist between patients who utilize these two styles of therapy. Quality-of-life research has emerged as a primary measure of health outcomes because it allows the augmentation of traditional clinical indicators of health with data gathered from the patient's perspective. A total of 1033 haemophilia patients from 16 European haemophilia treatment centres were enrolled in this study. The SF-36, a multidimensional quality-of-life instrument, was administered to all participants. This instrument measures eight health-related quality-of-life dimensions: physical functioning, physical role limitations, bodily pain, general health, vitality, social functioning, emotional role limitations, and mental health. All haemophilia subjects enrolled in the study scored significantly lower than the population normative means in the three physical dimensions and in the general health dimension. HIV-negative haemophiliac subjects differed significantly by factor substitution type in a multivariate analysis examining all eight health dimensions. Univariate analyses testing each dimension separately indicated that patients treated prophylactically reported significantly less bodily pain, better general health, and scored significantly higher in the physical functioning, mental health, and social functioning dimensions. While these results suggest that health-related quality-of-life may be better for haemophilia patients treated prophylactically, future prospective studies that gather periodic quality-of-life data over time should be conducted.

    Notes: Summary.  A multicentre, international, cross-sectional study was carried out in the frame of field testing of the first haemophilia-specific quality-of-life (QoL) questionnaire (Haemo-QoL). The aim of this paper is to describe health status and health care and their impact on QoL in haemophilic children in Western Europe. Children aged 4–16 years with severe haemophilia without inhibitors were enrolled by 20 centres in France, Germany, Italy, the Netherlands, Spain and the United Kingdom. Clinical information was collected by the physicians with a medical documentation form. Health-related QoL (HRQoL) of children was assessed with Haemo-QoL, available for three age groups. Clinical data were available in 318 patients, 85.5% with haemophilia A. The mean age at first bleeding was 11 months, at first joint bleed 25 months. Functional joint impairments were found in 11.3%. Prophylaxis treatment was given to 66.7% of children in whom breakthrough bleeds occurred 0.4 times a month compared to 1.1 bleeds in children receiving on-demand treatment. A significantly higher factor consumption was found only in the two younger age groups of prophylaxis patients compared to on-demand patients. HRQoL was satisfactory in this cohort: young children were impaired mainly in the dimension ‘family’ and ‘treatment’, whereas older children had higher impairments in the so-called ‘social’ dimensions, such as ‘perceived support’ and ‘friends’. Health care of children in Western Europe is progressively improving with a large diffusion of home treatment and prophylaxis. This provides a high level of health status and HRQoL, being better in haemophilic adolescents on prophylaxis.

    Notes: Summary.  Participants in an international workshop on surgery in haemophilia patients with inhibitors developed a consensus summary of the findings and conclusions of the meeting. In the consensus, participants agreed upon revised definitions for minor and major surgery, including an intermediate degree of surgery. An evaluation system of intraoperative and postoperative bleeding was developed. Recommended doses of FEIBA® and rFVIIa (both in bolus injections and in continuous infusion) for surgery were agreed. Participants also agreed on the main blood tests to be performed peri-operatively. They also suggested the need of a prospective evaluation in the future. Finally, the approximate number of surgical procedures and costs performed on haemophilia patients with inhibitors were analysed.
