Objective:
Acute bleeds in patients with rare bleeding disorders (RBDs), including congenital hemophilia with inhibitors (CHwI), acquired hemophilia, congenital factor VII deficiency, and Glanzmann’s thrombasthenia (GT) must be treated as quickly as possible. This study evaluated the obstacles and experiences of patients with CHwI, or their caregivers, for the early treatment of acute bleeds in non-hemophilia treatment centers (HTCs).
Methods:
Patients in the United States (aged 18–65 years [or caregivers of patients <18 years]) with CHwI, who currently have or have had inhibitors in the last 3–4 years, and who sought treatment in a non-HTC, underwent an interactive online qualitative discussion over 7 days.
Summary:
The survey was completed by 23 respondents (seven patients and 16 caregivers; all patients with CHwI). Respondents were aware of the need to treat bleeds quickly, which had been taught to them by physicians and learned from experience. Delays in respondents initiating their treatment were typically due to: technical issues (e.g., 7/23 respondents had difficulty gaining access to a vein or port); delay in diagnosis (e.g., 5/23 respondents’ child does not inform caregiver of the bleed); convenience (e.g., 3/23 respondents were unwilling/unable to take treatment out of the home); or financial issues (e.g., one respondent had inadequate insurance). Respondents tended to visit a non-HTC as a last resort, often due to the long distance to an HTC when emergency treatment was needed, unsuccessful pain management, or unsuccessful factor administration at home. Most patients/caregivers (20/23) reported treatment delays in emergency departments (EDs). Delays in EDs were often due to healthcare professional’s (HCP) lack of knowledge (16/23 respondents; 4 hours average wait until treatment) and four reported delays due to lack of available treatment (14 hours average wait for treatment). All patients/caregivers reported that they had dealt with uneducated/unaware HCPs, having to spend significant time educating the ED staff. Three respondents reported not waiting for treatment—partly because they chose hospitals very carefully, and because they had educated their closest hospital prior to needing an emergency service. Patients/caregivers with negative experiences reported that HCPs were unwilling to listen to them, did not seek consultation quickly, dismissed their instructions, and directed care that forced an outcome. When patients had satisfactory experiences, HCPs listened intently, immediately called an HTC/patient’s physician, and provided care in consultation. Respondents highlighted the need for HCPs education on hemophilia.
Conclusions:
Patients/caregivers are aware of the need to treat an acute bleed fast, but sometimes delay their treatment, and experience delays when attending non-HTCs. The lack of experience of HCPs in managing acute bleeds contributes to these delays. Improved education of HCPs at non-HTCs and provision of protocols or guidelines would be beneficial for patients with CHwI.
Background:
There are no reported cases of acute lymphoblastic leukemia (ALL) in patients with hemophilia B. There is one case report of a young adult with hemophilia B and acute myeloid leukemia (1). Currently, there is no best practice recommendation for the management of patients with hemophilia B and ALL.
Objectives:
To report our experience in managing a pediatric patient with congenital hemophilia B and ALL, which presents a rare and unique clinical challenge.
Design/Method:
Retrospective chart review
Results:
This is a 2y/o male with hemophilia B diagnosed at birth from a cord blood sample showing a factor IX level <1%. Mother is a known carrier and maternal grandfather has severe hemophilia B. Patient started prophylaxis with a standard half-life product through central venous access around 8months of age, following a spontaneous wrist bleed. The schedule was 35 units/kg twice a week. He had no spontaneous joint or soft tissue bleed on this regimen. 3mo ago he presented with pain and swelling of the right wrist. He fell on an outstretched hand the day before and received 100% factor infusion. X-ray showed metaphyseal lucencies with overlying soft tissue swelling. No evidence of fracture. Due to this finding, additional labs were done. WBC 4.8K, hemoglobin 7.1 g/dL, platelets 18K and 31% blasts. Flow cytometry confirmed the diagnosis of preB-ALL. On exam, he had pallor, scattered petechiae and cervical lymphadenopathy.
Based on recovery studies and thrombocytopenia, the prophylaxis was changed to 50 units/kg every third day. The platelets are kept above 30K at baseline. For lumbar punctures, he has been corrected to 100% factor level and platelets kept above 50K. However, due to the risk of port infection with frequent accessing, he was switched to long-acting albumin fusion factor IX product on day 22 of induction. The current prophylaxis regimen is 75units/kg weekly and the schedule is adjusted to coincide with lumbar puncture days whenever needed. He has tolerated all his procedures well without increased bleeding, including end of induction bone marrow aspiration, biopsy and lumbar puncture with intrathecal chemotherapy. He is currently in remission and is in interim maintenance phase of treatment per COG protocol AALL0932.
Conclusion:
Long-acting factor IX products could potentially decrease the number of infusions and need for frequent central venous access in immunocompromised patients with hemophilia B. In addition, a higher trough level with a weekly schedule could provide better bleed control in patients with severe thrombocytopenia due to underlying malignancy. A baseline platelet count of at least 30K is recommended during treatment. More treatment guidelines need to be established.

Objective:
Report on the utilization of a multi-point videoconferencing platform, Extensions for Community Healthcare Outcomes (ECHO), in providing a clinical learning opportunity to physical therapists (PTs) involved with people with bleeding disorders (PWBD) within Western States Region Hemophilia Treatment Centers (WSR HTC).
Methods:
WSR HTC includes thirteen HTC’s located in California, Nevada, Hawaii, and Guam. Monthly one-hour evidence based case presentations with a facilitated discussion were conducted using the ECHO platform. Each session was recorded, so all the therapists invited to participate have access to the information.
Data were collected from the WSR participating PTs by using anonymous on-line surveys, Qualtrics software (Qualtrics, Provo, UT), and prior to the start of the physical therapy ECHO session and upon completion of each session.
Descriptive statistics were calculated to evaluate the educational value of presentations.
Results:
Thirteen PTs, surveyed prior to the first PT ECHO session had reported > 6 years of experience as a PT. Twenty-three percent reported < 5 years of experience working with PWBD and over half of PT surveyed had > 16 years of experience working with PWBD.
Eight topics were presented in 2018 included musculoskeletal ultrasound imaging, invasive surgery rehab outcomes for patients with inhibitors, kinesiology taping, knee arthroplasty and stiffness, iliopsoas bleeding, myofascial decompression, chronic pain, knee bleed, and ankle joint impact from bleeding. An average of nine HTC PTs attended each session (range 4 to 18). Ten (11.2%) non-HTC PTs (outpatient PTs, HTC nurse, HTC Nurse Practitioner) attended some of the PT ECHO sessions. Table 1.
Ninety-five percent of respondents reported strong agreement with the program’s educational value and appropriateness for a practicing PT. Thirty-seven (94.9%) of responses reported agreement that the PT ECHO program improved their knowledge of physical therapy and bleeding disorders. Table 2.
Conclusion:
Videoconferencing platforms such as ECHO allows PTs in the WSR HTC, who are geographically separated to successfully share clinical knowledge to facilitate best practice in the area of specialty care for PWBD.

Hemophilia causes repetitive bleeding episodes throughout the musculoskeletal system, primarily into joints, such as knees and ankles. This leads to significant joint damage resulting in increased pain reproduction, decreased functional abilities, such as walking, and negatively impacts quality of life. Traditionally the extend of joint damage has been examined via clinical assessments, such as the Hemophilia Joint Health Scores, x-rays, MRIs, and more recently musculoskeletal ultrasound (MSKUS). However, these modalities fail to establish the global impact of joint damage on the entire body of a person with hemophilia and their functional abilities. Analyzing joint motion and forces acting upon the joint during walking has been a widely established technique to gain understanding of abnormal three-dimensional movements and is a key factor in clinical decision making-processes. With the overall goal of establishing better treatment approaches for persons with hemophilia it is vital to understand the underlying functional joint limitations. Therefore, the purpose of this study is to investigate characteristics of damaged joints, joint motion and control as well as forces acting upon the joint during walking in persons with hemophilia.
Objective:
To examine the frequency and methods used to screen patients for substance use and behavioral health disorders in Hemophilia Treatment Centers (HTC). We hypothesized that inconsistencies in methods utilized and frequency of utilization exist.
Methods:
Marshall University (MU) Physical Therapy faculty along with MU addiction education staff developed a 26-question survey using Qualtrics. The survey included questions on demographics, validated screening tools utilized, screening frequency, and team member responsible for screening. The HTC email addresses were obtained from the Hemophilia Treatment Center Directory on the CDC’s website. Following approval from MU IRB, the survey was disseminated via an online link. Descriptive analysis was performed on the data.
Summary:
Health professionals from 19 HTCs, representing 8 different regions, completed the survey. The overall response rate was 13.6%. Social workers (12, 63.2%), nurses (6, 31.6%)) and counselors/psychologists (1, 0.05%) submitted responses. On average HTCs reported 34.5% (0-92%) of their patients experience chronic pain with an average 22.4% (0-56%) receiving prescription opioids for pain management. Adverse consequences related to opioid use existed in all of the HTCs including overdose (31.5%), withdrawal symptoms (42.1%), increased dose due to tolerance (63.2%), and increased bleeding episodes (26.3%). The majority of HTCs (57.9%) reported being the primary provider of pain management for people with hemophilia (PWH). Standardized screening for substance use disorders is occurring 31.6% of the time with marijuana and illicit drugs (100%) being most commonly screened followed by alcohol and prescription drugs (83%) and tobacco at 33%. Frequency of screening for substance use varied widely from every comprehensive visit to initiation of an opiate contract to suspicion of misuse. Screening for behavioral health is more common (81.3%) with a variety of validated screening tools being utilized. Over 60% of the time, screening for anxiety and depression occurs either annually or every visit.
Conclusions:
PWH often develop chronic pain related to joint arthropathy.
Based on our findings, the incidence of chronic pain in PWH is relatively equal to the national average. HTCs are often the primary provider of pain management and are challenged to find safe treatment methods. PWH are often prescribed opioids which may place them at increased risk for potentially developing an opioid use disorder.
The presence of a behavioral health disorder may further enhance one’s risk. Although behavioral health screenings appear to be more consistently utilized in HTCs, substance use screenings are rare. Our research suggests that universal screening for substance use and behavioral health conditions should be considered, as a standard of care in HTCs, to better inform healthcare providers of patient risk, need for referral and to guide prescriber’s decision making with regard to pain management options.
Objective:
Persons with bleeding disorders experience pain in association with needle pokes, joint and muscle bleeds and permanent tissue damage. The impact of this pain on patients can include time off school or work, a change in career, income, stress, mental health concerns and change in relationships. Comprehensive pain management includes strategies from the “Four P’s of Pain Management” which include pharmacological, physical, psychological and prevention.
The aim of the project was to examine current psychological knowledge and management of pain within our patient population. This study asked the following research questions: 1) What is currently understood about pain and bleeding disorder care among social workers (CSWHC)? 2) What specific pain knowledge and training is prioritized by social workers in Hemophilia Treatment Centres?
A scoping review was conducted concurrently with the qualitative study. Medline and SocIndex were searched with the terms “social work” and “pain management” and a second search was conducted with the term “social work and hemophilia/von willebrand's or platelet disorders”. A total of 105 articles were examined by three independent reviewers. Eleven articles have been included for the purpose of examining the role of social work in pain management.
Methods:
Qualitative interviews were conducted and recorded with 12 social workers from the CSWHC between September 2018 and February 2019. Five provinces were represented. Social work participants were deployed within paediatric, adult or within combined clinics. The interviews were approximately 20-45 minutes. Transcribed interviews were coded with NVivo by two independent reviewers with Thematic Analysis.
Summary:
Social workers identified the roles of social work to include completion of psychosocial assessments and meeting the practical needs of patients, while supporting patients in medical decisions. Barriers to pain management and the impact of pain on patients were described as having an impact on individuals and families. Social workers also discussed their understanding of acute and chronic pain in patients, which has indicated an increase of knowledge is required. Skills development in multi-dimensional nature of pain and pain assessment were determined to be most likely to produce positive impact on practice outcomes. Initial themes include hope, relationship of trust, stigma (diagnosis vs. pain), defining multidisciplinary roles.
Conclusion:
Study results, first, will contribute to the literature supporting the need for social work education for those practicing in bleeding disorder care. Secondly, they will provide recommendations for an educational pain curriculum for social workers in bleeding disorder care. This education will reflect the need for pain knowledge in acute and chronic pain dimensions which will facilitate dialog with other professionals in pain management. Pain assessment will also be a focus in order for social workers to be able to support and provide appropriate referrals for pain management.
Objective:
Inhibitor development is the most serious complication of hemophilia A therapy. Immune tolerance induction (ITI) is the gold standard for inhibitor eradication, restoring factor VIII (FVIII) responsiveness. Retrospective data on ITI therapy using rFVIIIFc have been reported (Carcao et al. Haemophilia. 2018). The ReITIrate study (NCT03103542) was designed to prospectively evaluate success of rescue ITI with rFVIIIFc.
Methods:
ReITIrate, a prospective, interventional, multicenter, open-label study, enrolled patients with severe hemophilia A and inhibitors, who failed previous ITI attempts. The primary purpose is to describe the outcome of ITI performed with rFVIIIFc (200 IU/kg/day) within a maximum of 60 weeks. Here, patient baseline characteristics are reported using descriptive statistics and listings.
Summary:
Sixteen subjects were included in the study between November 2017 and December 2018. The median (range) age at study enrollment was 7.5 (2–46) years. Seven subjects had a known family history of inhibitors. The median (range) number of prior ITI attempts was 1 (1–3) and the median (range) total ITI duration was 51.5 (12–155) months. All subjects had previously received high-dose ITI, with 3 subjects receiving plasma products, 6 subjects receiving recombinant products, and 7 subjects receiving both recombinant and plasma products for previous courses of ITI. Four subjects received prior immunomodulatory therapy. The median (range) inhibitor titer at screening and historical peak were 11 (0.9–635) BU/mL and 127 (8–3000) BU/mL, respectively. During the 12 months prior to enrollment, the median (range) number of bleeds was 5 (0–24); 11 subjects used activated prothrombin complex concentrate (aPCC) for treatment of bleeds, 5 subjects received recombinant factor VIIa (rFVIIa), and 1 subject each received FVIII/von Willebrand factor, recombinant FVIII, and tranexamic acid. Twelve subjects received prophylaxis with bypassing agents during this period (10 aPCC, 1 rFVIIa, and 1 both products).
Conclusions:
This is the first prospective study describing rescue ITI with an extended half-life recombinant FVIII product. Enrolled subjects had multiple risk factors for poor ITI outcomes and a long duration of previous ITI. There is an unmet need for successful tolerization in such patients, allowing regular FVIII prophylaxis and potentially leading to improved clinical outcomes and quality of life.
Objective:
The completed pediatric phase 3 pathfinder 5 trial assessed the safety and efficacy of N8-GP (turoctocog alfa pegol, ESPEROCT®) use for routine prophylaxis and treatment of breakthrough bleeds in previously treated children.
Methods:
pathfinder 5 was a multicenter, multinational, single-arm study evaluating safety, efficacy, and pharmacokinetics. Children (aged <12) with severe hemophilia A were administered prophylaxis (target 60 [50-75] IU/kg twice weekly) in the main phase (26 weeks) followed by an extension phase. Current analysis covers study initiation (February 2013) through completion (September 2018).
Summary:
Of the 68 children (34 aged 0-5, 34 aged 6-11) enrolled, 63 completed the main phase and 62 completed the extension. Most (95%) were previously on prophylaxis. The total study period amounted to 306 patient-years (32,138 exposure days); median (mean) patient exposure was 4.9 (4.5) years.
Overall, 838 adverse events (AEs) were reported; 18 serious AEs included 2 possibly/probably related to N8-GP (severe allergic reaction [1] and increasing bleeding symptoms [1]). No inhibitor development was observed in the trial. Two AEs resulted in withdrawal; a third patient with severe allergic reactions (after 4 doses) that resolved after 2 hours without any treatment met preestablished withdrawal criteria. There were no anti-PEG antibodies of clinical significance; however, 21 (31%) patients had anti-PEG antibodies at baseline (prior to exposure), and 1 patient had a single positive measurement after exposure at a titer <1.
Overall, 55 patients (81%) reported 330 bleeds during the study; most were traumatic (67%). The success rate for hemostasis was 84% (excellent/good); 71% were treated with 1 injection, and 88% of patients were successfully treated with 1-2 injections. Median (mean) utilization for bleeds was 68 (95) IU/kg.
Median ABRs are shown below; estimated mean ABR was 1.1. Forty-seven percent of children had no spontaneous bleeds throughout the trial. Of 13 children with 17 target joints at baseline, 77% (main phase) and 46% (complete trial) reported no bleeds in their target joints. For those previously on prophylaxis, the mean observed ABR was 2.3 compared with the historical ABR of 6.4. The mean prophylaxis dose was 64.7 IU/kg with an interval of 3.5 days.
| Median ABR | Age 0-5 y | Age 6-11 y | Total |
| Overall | 0.6 | 0.9 | 0.8 |
| Spontaneous | 0.1 | 0.2 | 0.2 |
| Traumatic | 0.3 | 0.8 | 0.5 |
N8-GP prolonged single dose half-life by 1.9x compared with the child’s prior FVIII product. The mean trough levels on twice-weekly dosing were 0.019 IU/mL (0.016 ages 0-5, 0.024 ages 6-11).
Conclusion:
These data support the safety and efficacy of N8-GP in a controlled phase 3 trial setting in children. Prophylaxis with N8-GP using a consistent dose/interval (65 IU/kg twice weekly) was effective in preventing bleeds. No unexpected safety issues were identified.
