To describe the in-hospital epidemiology of haemophilia A and B in the US we analysed the National Inpatient Sample (NIS), a stratified probability sample of 20% of all hospital discharges in the US for the year 2007. We applied sampling weights to represent all hospital discharges for haemophilia A and B identified using ICD-9 codes 286.0 and 286.1, respectively. Haemophilia (A or B) was one of all the listed diagnoses in 9737 discharges and principal diagnosis in 1684 discharges. The most common associated diagnoses in discharges with Haemophilia in adults and children were hypertension (28.1 ± 1.6%) and central line infections (15.2 ± 1.8%) respectively. No Hepatitis C or HIV was reported in children. Among 212 deaths, associated diagnoses included sepsis (37.9%), heart failure (30.2%), respiratory failure (28.3%), pneumonia (24.5%), HIV (14.2%), hepatic coma (5.2%) and intracranial haemorrhage (2.3%). All fifteen reported paediatric deaths occurred on day zero of life, the commonest associated diagnoses being Intraventricular haemorrhage and newborn haemorrhage-NOS (33% each). Median age of in-hospital mortality for diagnosis of Haemophilia was 68.3 years as compared to 72.3 years for all males for all hospitalizations in NIS combined. Mean hospital charges for haemophilia of $76823 ± 5530 were significantly higher than those from all causes of hospitalization of $26,120 ± 562. In-hospital mortality is rare in children with haemophilia beyond the neonatal period and age of mortality in adults is approaching that of the general male population. Hospitalization in children is most often due to central line infections and hospitalization and death in adults is primarily due to age-related illnesses.

    ABSTRACT: Substantial improvements in the safety of blood and plasma products for the management of bleeding disorders have been achieved in recent decades. This has led some clinicians to believe that the infectious threat is over and that inhibitor formation is the foremost complication of hemophilia therapy. On the contrary, elimination of all microbes from blood is difficult, potentially impossible, and there are always threats from emerging pathogens. The risk of infection transmission is also increasing due to greater exposure to products, increasing prophylaxis and high-dose regimens for immune tolerance, and longevity of hemophilia patients. Current products can be considered "reasonably safe," but pathogen testing is not all-inclusive, and manufacturing and purification techniques are often not standardized. Although safer nonplasma-derived products are widely used, they are not available for all bleeding disorders, and so there is an ongoing need for plasma-derived products. This review will discuss the evolving risk from emerging pathogens in the context of the issues described. Reducing the risk from emerging infections requires global collaboration to devise ways to monitor and continue to improve blood safety.

    ABSTRACT: With advances in care, increasing numbers of people with hemophilia achieve near-normal life expectancies and present with typical age-related cardiovascular conditions. Evidence-based guidelines for medical or surgical management of cardiovascular conditions in individuals with hemophilia are limited. Published recommendations exist for the management of some common cardiovascular conditions (e.g., ischemic heart disease, atrial fibrillation), but identifying optimal strategies for anticoagulant or antithrombotic therapy constitutes the primary challenge of managing non-operative cardiovascular disease in people with hemophilia. In general, as long as factor concentrates or other hemostatic therapies maintain adequate hemostasis, the recommended medical and surgical management of cardiovascular disease in people with hemophilia parallels that in individuals without hemophilia. The presence of factor inhibitors complicates hemophilia management. Published outcomes of cardiovascular disease treatment in people with hemophilia are similar to those in the general population. Specific knowledge about factor replacement, factor inhibitors, and disease-specific treatment distinguishes the cardiovascular care of people with hemophilia from similar care of individuals without this rare bleeding disorder. Furthermore, a multidisciplinary approach incorporating a hematologist with an onsite coagulation laboratory, ideally associated with a hemophilia treatment center, is integral to the management of cardiovascular disease in people with hemophilia.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 3.0 License, where it is permissible to download and share the work provided it is properly cited.

    ABSTRACT: Central venous access devices (CVADs) are used in the care of paediatric haemophilic patients with difficult peripheral access, but their use is limited by complications such as infection. We previously published our experience with monthly recombinant tissue plasminogen activator (r-tPA) administration to CVADs of haemophilic patients as an intervention for infection prophylaxis, which suggested a 10-fold decrease in infection rate compared to published rates without r-tPA. This study was conducted to assess the CVAD infection rate in an expanded haemophilia cohort receiving r-tPA over an extended period. A retrospective review was performed on patients with haemophilia who received monthly r-tPA to CVADs, with data collected from January 1, 2008 to December 31, 2012. The data were merged with the previously reported data set (collected from June 1, 1998 to December 31, 2007). Over the entire observation period, there were 46 350 CVAD days among 32 patients [26 severe factor VIII (FVIII) deficiency, six severe FIX deficiency]. Eight patients received immune tolerance therapy for inhibitors and 24 patients received prophylactic factor administration. No patients were HIV positive. Three infections were observed, with an overall infection rate of 0.06 infections per 1000 CVAD days. A low CVAD infection rate, similar to that observed in our previous study (0.04 per 1000 CVAD days), was observed in this expanded haemophilia cohort treated with prophylactic r-tPA, supporting the use of monthly r-tPA as CVAD infection prophylaxis in haemophilia patients. © 2015 John Wiley & Sons Ltd.
