A clinical practice guideline for primary care physiotherapy in patients with haemophilia

INTRODUCTION

As a result of centralisation of haemophilia care to a limited number of intramural settings, many persons with haemophilia have to travel long distances to attend their haemophilia specialised treatment centre. However, regular physiotherapy treatment can be provided by primary care physiotherapists in the person's own region. Due to the rarity of the disease most primary care physiotherapists have limited experience with this population. This study aims to provide a clinical practice guideline for primary care physiotherapists working with persons with bleeding disorders.

METHOD

A list of the most urgent key-questions was derived from a previous study. Literature was summarised using the grading of recommendations assessment, development, and evaluation (GRADE) evidence-to-decision framework. Recommendations were drafted based on four 90 min consensus meetings with expert physiotherapists. Recommendations were finalised after feedback and >80% consensus of all stakeholders (including PWH, physiotherapists, haematologists and the corresponding societies).

RESULTS

A list of 82 recommendations was formulated to support primary care physiotherapists when treating a person with a bleeding disorder. These recommendations could be divided into 13 categories: two including recommendations on organisation of care, six on therapy for adult patients with bleeding disorders and five on therapy adaptations for paediatric care. Therapy recommendations included treatment after a joint- or muscle bleed, haemophilic arthropathy, chronic synovitis, non-haemophilia related conditions and orthopaedic surgery.

CONCLUSION

An evidence-based practice guideline, based on current evidence from literature and clinical expertise, has been developed for primary care physiotherapists treating a person with haemophilia. To improve care, the recommendations should be implemented in daily practice.

Total Knee Arthroplasty in People with Hemophilia: Higher Incidence of Periprosthetic Joint Infection and 1-Year Revision/Re-Operation than the General Population and Lower Prosthetic Survival When Early Postoperative Bleeding Complications Occurred: Current Literature Review

The purpose of this narrative review of the recent literature is to analyze the outcomes, complications, and implant survival of total knee arthroplasty (TKA) carried out on people with hemophilia (PWH). It has been shown that TKA substantially alleviates preoperative pain and improves knee function and the patient's quality of life. However, the complication rates of TKA range between 8.5% and 28.7, with postoperative hemarthrosis being the most frequent (7.6%). Besides, when comparing if the TKA was implanted before or after the year 2000, a reduction was found in the rates of periprosthetic joint infection-PJI (6.2% to 3.9%) and aseptic loosening (3.8% to 2.1%). Comparing prosthesis survival between PWH who had suffered early postoperative bleeding complications (EPBC) and patients who did not suffer EBPC, the mean survival duration was 17 years for the EPBC group and 22.1 years for the non-EPBC group. Survival rates were 80% for the EPBC group and 96.4% for the non-EPBC group. Compared to patients without hemophilia, PWH had a substantially higher incidence of PJI (Odds Ratio-OR 1.6) and 1-year revision/re-operation (OR 1.4). In short, although TKA substantially improves the quality of life of PWH, it is an intervention that has a non-negligible percentage of complications. TKA in PWH should preferably be performed only in highly specialized centers for the orthopedic treatment of hemophilia.

Arthroscopic ankle surgery in people with haemophilia

INTRODUCTION

People with haemophilia (PWH) not administered primary haematological prophylaxis since childhood, that is, those treated haematologically on demand or not treated at all, often experience the degeneration of the ankles, leading to pain and functional impairment.

AIM

To analyse the outcomes and complications of arthroscopic ankle surgery performed on PWH.

METHODS

For this narrative review of the literature, a search was conducted in PubMed on 2, December 2023, using the keywords "haemophilia", "ankle" and "arthroscopy". Of the 29 articles identified, 15 specifically related to ankle arthroscopy in PWH were selected (inclusion criterion). The remaining articles did not meet this requirement (exclusion criterion) and were therefore eliminated.

RESULTS

Arthroscopic procedures (arthroscopic synovectomy, debridement and arthrodesis of the ankle) are increasingly used in the surgical treatment of haemophilic ankle arthropathy. Although arthroscopic ankle surgery offers good outcomes in patients with haemophilia, the procedure is not free of complications, which range from 7.9% for arthroscopic ankle debridement to 13.1% in arthroscopic ankle synovectomy and 17.8% in arthroscopic ankle arthrodesis, respectively. The non-union rate of arthroscopic ankle arthrodesis is 7.1% (2/28).

CONCLUSION

Although arthroscopic interventions in the haemophilic ankle (synovectomy, debridement, arthrodesis) offer good functional outcomes, they are associated with a non-negligible rate of complications. Arthroscopic ankle surgery in PWH is major surgery and should be treated as such.

Ultrasound Evaluation of Tendinopathy in Hemophiliac Patients for the Purpose of Rehabilitation Indications

BACKGROUND

Hemophilia is a inherited bleeding disorder that is characterized by intra-articular bleeding (hemarthrosis). The aim of the study was to evaluate the state of the satellite tendons of the target joints in the patient with hemophilic arthropathy and propose rehabilitation treatment with eccentric exercises.

METHODS

The tendons of the joints mainly affected by hemophilic arthropathy were evaluated by ultrasound. The ultrasound evaluation is associated with the use of evaluation clinical scales, such as the Hemophilia Joint Health Score (HJHS), the Functional Independence Score in Hemophilia (FISH), the Hemophilia Activity List (HAL), the DASH, the VISA-A, the VISA-P, and the VAS scale.

RESULTS

In 20 patients with hemophilic arthropathy, the thickness of the tendons that were examined was normal. In six subjects with severe joint damage, echostructural alterations were present, and signs of hyperemia and neo-vascularization were detected on color Doppler, as well as the presence of intratendinous calcifications.

CONCLUSIONS

The tendons of the target joints in patients with hemophilic arthropathy are compromised by the indirect biomechanical damage caused by the joint disease, and rehabilitation treatment with eccentric exercises can be considered safe and effective in improving the tenso-elastic properties of the tendons.

Hemophilic arthropathy: how to diagnose subclinical bleeding early and how to orthopedically treat a damaged joint

INTRODUCTION

It is important to know the current status of hemophilic arthropathy diagnoses, treatments, complications, and outcomes in developed countries.

AREAS COVERED

A bibliographic search in PubMed for articles published from 1 January 2019 through 12 June 2023 was performed.

EXPERT OPINION

In developed countries with specialized hemophilia treatment centers, primary hematological prophylaxis (started before the age of 2 years and after no more than one joint bleed) has almost completely eliminated the joint-related problems of the disease. The ideal goal of zero hemarthroses can be achieved only with intense and well-dosed prophylaxis: intravenous infusion of coagulation factor - standard half-life or extended half-life; periodic or subcutaneous injections of nonfactor products (emicizumab or fitusiran). However, hemophilic arthropathy continues to occur due to subclinical joint hemorrhages. In one study, 16% of the joints without reported hemarthroses showed signs of previous subclinical bleeding (hemosiderin deposits with/without synovial hypertrophy on magnetic resonance imaging were deemed signs of previous subclinical bleeding), rendering evidence for subclinical bleeding in people with severe hemophilia with lifelong prophylaxis treatment. Subclinical joint hemorrhages can be averted only by employing accurate and tailored prophylaxis.

Synovitis in hemophilia: preventing, detecting, and treating joint bleeds

INTRODUCTION

Most bleeding events in individuals with hemophilia occur within the ankle, knee, and elbow joints. Should the bleeding persist, the synovial membrane starts to hypertrophy and a vicious cycle of chronic hemophilic synovitis (CHS) occurs, leading to joint destruction.

AREAS COVERED

This article covers the prompt diagnosis of CHS by point-of-care ultrasonography (POC-US) and its treatment by means of several types of synovectomy.

EXPERT OPINION

It is essential to prevent, detect and treat hemophilic synovitis, because it indicates that the joint has bled and is at risk of bleeding further. Prophylaxis with standard half life (SHL) factor VIII (FVIII) concentrate is the standard of care for individuals with severe hemophilia A and can also be considered for selected patients with moderate disease. Several years of real-world experience with extended half life (EHL) FVIII, emicizumab, and other drugs in development will be needed to ascertain their final effect on bleeding and its complications. We must look for synovitis in individuals declaring joint pain and in asymptomatic patients, and POC-US is the most reasonable imaging instrument with which to carry out periodic joint screening. Radiosynovectomy, chemical synovectomy, and arthroscopic synovectomy markedly reduce bleeding events.

Effectiveness of therapeutic exercise and cognitive-behavioural therapy combined protocol on functionality, pain and joint health in people with haemophilia: Secondary analysis of a controlled trial

BACKGROUND

Haemophilic arthropathy is one of the main causes of morbidity in people with haemophilia (PWH), inducing pain and reduced functionality. Therefore, PWH are complex patients and must be approached from a multidisciplinary perspective.

OBJECTIVES

To evaluate the effectiveness of a therapeutic exercise and cognitive-behavioural therapy (CBT) combined protocol on functionality, pain, and joint health of PWH, arthropathy and chronic pain. Treatment satisfaction was also evaluated.

METHODS

A single-blinded clinical trial with 21 PWH in prophylactic regimen was carried out. Participants were divided into an experimental group (EG, n = 11) and a control group (CG, n = 10). The EG underwent a 4-month programme of home-based therapeutic exercise plus CBT, whilst CG performed their daily activities. Patients were evaluated at baseline, post-intervention and after 12 additional weeks. Measures of functionality (Haemophilia Activities List, Timed Up and Go Test, 2-Minutes-Walking-Test and Sit-to-Stand Test), pain (PainDETECT and Visual Analogue Scale) and joint health (Haemophilia Joint Health Score) were taken. Related dimensions of the A36 Haemophilia Quality of Life Questionnaire were calculated. Effects were calculated using a two-factor ANOVA.

RESULTS

The EG showed significant improvements in function (p < .001), pain (p < .001), joint damage (p = .006), and satisfaction with the treatment (p = .006) dimensions of the A36 Haemophilia Quality of Life Questionnaire, as well as in pain measured with the Visual Analogue Scale (p = .008) and PainDETECT (p = .035).

CONCLUSIONS

The combined physiotherapy and CBT protocol showed a partial improvement in functionality, pain and joint health of PWH, arthropathy and chronic pain. In addition, participants were satisfied with the treatment.

Osteoporosis in hemophilia: what is its importance in clinical practice?

INTRODUCTION

The relationship between severe hemophilia and osteoporosis has been well established in the literature. However, although the importance of its prevention in order to reduce the risk of bone fractures has been reported, the importance of its treatment in clinical practice has not been well analyzed.

AREAS COVERED

In this paper a review of the available clinical and experimental information on osteoporosis in hemophilia has been performed, to better understand the relationship between hemophilia and osteoporosis. Prevention of osteoporosis in hemophilia should include primary hematological prophylaxis; a diet appropriate in calcium and vitamin D; a regular exercise program that includes aerobics, strength training and balance and flexibility activities; restriction of tobacco and alcohol use; and limitation of the duration of immobilization.

EXPERT OPINION

Prevention of osteoporosis in hemophilic patients is paramount. However, it is noteworthy that there is only one publication on the treatment of osteoporosis in patients with hemophilia. Until further research is done on this topic, the existing recommendations for non-hemophilic patients should be followed. They include the use of antiresorptives (estrogens, selective estrogen receptor modulators, bisphosphonates, denosumab) and anabolic agents (teriparatide, abaloparatide, romosozumab). Further studies on the management of osteoporosis in patients with hemophilia are required.

Total knee arthroplasty in hemophilia: lessons learned and projections of what's next for hemophilic knee joint health

INTRODUCTION

The purpose of this article has been to review the literature on total knee arthroplasty (TKA) in people with hemophilia (PWH), to mention the lessons we have learned from our own experience and to try to find out what the future of this type of surgery will be.

AREAS COVERED

A Cochrane Library and PubMed (MEDLINE) search of studies related to TKA PWH was analyzed. In PWH, the complication rate after TKA can be up to 31.5%. These include infection (7.1%) and bleeding in the form of hematoma, hemarthrosis or popliteal artery injury (8.9%). In a meta-analysis the revision arthroplasty rate was 6.3%. One-stage or two-stage revision arthroplasty due to infection (septic loosening) is not always successful despite providing correct treatment (both hematological and surgical). In fact, the risk of prosthetic re-infection is about 10%. It is necessary to perform a re-revision arthroplasty, which is a high-risk and technically difficult surgery that can sometimes end in knee arthrodesis or above-the-knee amputation of the limb.

EXPERT OPINION

TKA (both primary and revision) should be performed in centers specialized in orthopedic surgery and rehabilitation (knee) and hematology (hemophilia), and with optimal coordination between the medical team.

Promoting physical activity in people with haemophilia: the MEMO (Movement for persons with haEMOphilia) expert consensus project

Regular physical activity can increase joint stability and function, reduce the risk of injury, and improve quality of life of people with haemophilia (PwH). However, a recent review of the literature shows that appropriate physical activity and sport are not always promoted enough in the overall management of PwH. A group of Italian experts in haemophilia care undertook a consensus procedure to provide practical guidance on when and how to recommend physical exercise programmes to PwH in clinical practice. Three main topics were identified -haemophilia and its impact on movement, physical activity recommendations for PwH, and choice and management of sports activity in PwH- and ten statements were formulated. A modified Delphi approach was used to reach a consensus. The group also created practical tools proposing different physical activities and frequencies for different age groups, the Movement Pyramids, to be shared and discussed with patients and caregivers. In conclusion, in the opinion of the working group, physical activity can be considered as a low-price intervention that can prevent/reduce the occurrence of chronic diseases and should be further encouraged in PwH to obtain multiple physical and psychological benefits. Future research should include prospective studies focusing on participation in sports, specific risk exposure and clinical outcomes.

Effectiveness of rehabilitation on pain and function in people affected by hemophilia

INTRODUCTION

Literature provides unclear evidence of the effectiveness of many physiotherapy interventions on pain intensity, quality of life, and functional ability in hemophilic patients, and suggests that rehabilitation programs should be focused on functional goals and the disability of patients.

AIM

The aim of the present study is to present the outcome of a case series of patients with hemophilia in which a rehabilitation program has been carried out on the basis of a specific individual patient's functional impairment.

METHODS

Fifty-one patients were enrolled: 32 patients (Rehab Group) received a rehabilitative treatment, 19 patients for different reasons (living far from the hospital, family problems) did not receive rehabilitation (Control Group). The rehabilitation program was planned with respect to the emergent problems: musculoskeletal pain, joint range of motion limitation, muscle flexibility, walking difficulties, the appearance of hematomas/hemartro, and postural problems. All the patients were assessed at baseline (T0), after 1 month (T1), and after 3 months (T2) through visual analogic scale for musculoskeletal pain, the Hemophilia Joint Health Score for joint range of motion, the Functional Independence Score in Hemophilia for disability, and postural assessment by visual inspection.

RESULTS

A significant reduction of pain and improvement of Hemophilia Joint Health Score and Functional Independence Score in Hemophilia score was found in the Rehab Group along with the follow-up. Pain in the Control Group was lower with respect to the other group at baseline and significantly decreased after 1 month.

CONCLUSION

A rehabilitation program focused on individual impairment of patients with hemophylia determined satisfying results in terms of pain control, functional, and disability improvement in 3 months follow-up.

Hemophilia Patient Experience in a Physical Therapy-Guided Health Education Intervention: A Mixed-Method Design

People with hemophilia usually have negative joint consequences due to their illness. Evidence suggests that exercise and therapeutic education bring some benefits. An important factor that affects health interventions was the experience and degree of satisfaction. Thus, it is relevant to analyze qualitative and quantitative data to obtain a complete view of the patient’s experience. As a result, a concurrent nested mixed method with quantitative predominance study design was carried out. Nine people with hemophilia of Hemoaralar with a homogeneous environment participated in this study. The items evaluated were the level of satisfaction through the GCPC-UN-ESU survey and the experience with healthcare interventions through a focus group. A high level of satisfaction was obtained, but some divergences between quantitative and qualitative data were found. Further research about physical therapy and this type of intervention in people with hemophilia should be considered to better address the impact of living with the disease.

Hemophilic arthropathy: a teaching approach devoted to hemophilia treaters in under-development countries

INTRODUCTION

Arthropathy is the characteristic injury of hemophilia, primarily occurring in the elbows, knees, and ankles. The aim of this review is a teaching approach devoted to hemophilia treaters in under-development countries.

AREAS COVERED

Current major challenges include the absence of the following therapeutic tools for all people with hemophilia (PWH) worldwide: hematological prophylaxis; well-coordinated multidisciplinary teams in specialized centers; joint aspiration of acute hemarthrosis; point-of-care ultrasonography (POC-US); exercise; treatment of synovitis by means of radiosynovectomy; treatment of mild hemophilic arthropathy with analgesics, anti-inflammatory agents, and rehabilitation medicine; intra-articular injections of corticosteroids, hyaluronic acid, platelet-rich plasma, and mesenchymal stem cells; and treatment of severe hemophilic arthropathy by surgical treatment. The future scenario in under-development countries should include all the aforementioned treatment tools plus the possibility of performing total joint arthroplasty in PWH with inhibitors; concomitant use of bypassing agents with emicizumab for PWH with inhibitors undergoing orthopedic surgery; and telemedicine.

EXPERT OPINION

Primary hematological prophylaxis is now the gold standard for the management of hemophilia. Acute hemarthrosis needs intense hematological management and articular aspiration; the articular situation should be scrutinized by POC-US. Synovitis can be controlled by radiosynovectomy. In cases of severe articular degeneration, surgical procedures might be required.

Applying World Health Organization 2020 guidelines on physical activity and sedentary behavior to people with hemophilia

Introduction: The new World Health Organization (WHO) guidelines on physical activity incorporate new concepts, such as sedentary behavior, recommendations for specific age groups and for people living with chronic conditions and disability. This could be extrapolated for the first time to people with hemophilia (PWH) within the framework in which these recommendations are applicable. The benefits of physical activity for PWH include physical, psychological and social benefits.Areas covered: This is a narrative review of the literature. We searched the MEDLINE and the Cochrane Library for WHO guidelines and articles related to physical activity in PWH. For all population groups, the benefits of performing exercise outweigh the possible harms. In PWH, there is a perceived increased risk of bleeding associated with physical activity. However, research suggests that this risk is associated with trauma during activity rather than intensity of physical activity, which offers the most health benefits.Expert opinion: Given the hematological, physical and functional conditions of PWH are highly variable, individualized counseling is needed based on age, therapeutic strategy, degree of arthropathy and level of disability. In this article, we analyze the applicability of the WHO recommendations to PWH, which is important to further promote healthy lifestyle motivation.

The Hemarthrosis-Simulating Knee Model: A Useful Tool for Individualized Education in Patients with Hemophilia (GEFACET Study)

Background

Hemophilic arthropathy is a major complication in patients with severe hemophilia. A plastic knee model has been developed for the therapeutic education of patients to promote improved care management and self-treatment skills. The objective of this study was to evaluate the impact of this hemarthrosis-simulating artificial knee (HSAK) on patients’ knowledge of their disease and its treatment.

Methods

In this observational study, the impact of HSAK was assessed during individualized education in patients with severe/moderately severe hemophilia A or B at seven hemophilia treatment centers in France. Participants provided written informed consent and completed questionnaires to assess knowledge of their disease (score range: 0–7) and knowledge of their treatment (score range: 0–4). Questionnaires were completed before, immediately after and 6 months after HSAK use. The scores obtained before and after the use of the HSAK were compared.

Results

The participants comprised 32 children, 29 teenagers, and 31 adults. The mean (SD) disease knowledge score increased significantly in all age groups of patients from 4.5 (2.0) to 5.9 (1.5; p<0.001) immediately after the training and remained unchanged at 6 months. Mean (SD) treatment knowledge scores were unchanged, but Wilcoxon signed rank testing showed a significant increase after the training course that was maintained at 6 months in children and teenagers.

Conclusion

These findings suggest that an individualized training course can enhance the understanding of hemophilia in patients of all ages, especially in children and teenagers, and that the HSAK may assist in improving patients’ management of their disease.

Effect of Pulsed Electromagnetic Fields on Clinical Signs and Quality of Life in Patients with Hemophilic Arthropathy of the Knee Joint: A Randomized Controlled Trial

BACKGROUND

Hemophilic arthropathy (HA) causes severe joint damage and impairs the quality of life (QoL) of hemophiliacs. This study was undertaken to evaluate the effect of pulsed electromagnetic fields (PEMFs) on the clinical signs and QoL of patients with severe hemophilia A experiencing moderate HA in the knee joint.

MATERIALS AND METHODS

Thirty-six severe hemophiliacs with HA of the knee joint were randomly assigned into the PEMF (n = 20) or placebo (n = 16) groups. The PEMF group received 60 min of PEMF (2 Hz, 25 Gauss for 30 min and 70 Hz, 30 Gauss for 30 min) on the knee joint, three times per week for 6 weeks. The clinical signs, QoL, and pain intensity were measured by the Hemophilia Joint Health Score, A36 Hemofilia-QoL Questionnaire, and visual analog scale, respectively, before and after treatment.

RESULTS

In the PEMF group, a significant difference before and after intervention in terms of clinical signs, QoL, and pain intensity (P < 0.05) was founded. Between-group analysis showed a significant improvement in clinical signs (except for atrophy, strength, and swelling duration), QoL, and pain intensity in the PEMF versus control group (P < 0.05).

CONCLUSIONS

PEMF can improve the clinical signs, QoL, and pain intensity of severe hemophilia A patient with moderate knee hemophilic arthropathy.

Complications of hemophilia in the elbow: current management

INTRODUCTION

After the ankle and knee, the elbow is the most commonly impaired joint in patients with hemophilia.

AREAS COVERED

A Cochrane Library and PubMed (MEDLINE) search related to elbow problems in hemophilia was conducted. Early and continuous primary hematological prophylaxis (ideally starting in infancy) is essential, given that the juvenile elbow is highly prone to the musculoskeletal complications of hemophilia. If primary hematological prophylaxis is not administered (due either to lack of affordability or lack of venous access), persistent hemarthrosis can occur in the elbow. Hemarthroses will then require aggressive treatment (through arthrocentesis under factor factor coverage) to prevent progression to synovitis (requiring prompt radiosynovectomy or arthroscopic synovectomy) and ultimately hemophilic arthropathy (requiring rehabilitation and orthopedic surgery). Between the second and fourth decade of life, many patients with hemophilia present elbow joint destruction.

EXPERT OPINION

In the initial stage of joint destruction, rehabilitation and intraarticular injections of hyaluronic acid can relieve the symptoms. In the advanced stage of hemophilic arthropathy, however, surgery is necessary. The main surgical procedures currently available are arthroscopic debridement, radial head resection, and total elbow arthroplasty. Transposition of the ulnar nerve and removal of heterotopic ossifications might also be necessary.

Predictors of treatment adherence in patients with chronic disease using the Multidimensional Adherence Model: unique considerations for patients with haemophilia

Introduction

Adherence to treatment recommendations in patients with chronic disease is complex and is influenced by numerous factors. Haemophilia is a chronic disease with reported levels of adherence ranging from 17–82%.

Aim

Based on the theoretical foundation of the World Health Organization Multidimensional Adherence Model, the objective of this study was to identify the best combination of the variables infusion frequency, annualised bleed rate, age, distance to haemophilia treatment centre (HTC) and Haemophilia Joint Health Score (HJHS), to predict adherence to treatment recommendations in patients with haemophilia A and B on home infusion prophylaxis in Canada.

Methods

A one-year retrospective cohort study investigated adherence to treatment recommendations using two measures: 1) subjective report via home infusion diaries, and 2) objective report of inventory ordered from Canadian Blood Services. Stepwise regression was performed for both measures.

Results

Eighty-seven patients with haemophilia A and B, median age 21 years, were included. Adherence for both measures was 81% and 93% respectively. The sample consisted largely of patients performing an infusion frequency of every other day (34%). Median scores on the HJHS was 10.5; annualised bleed rate was two. Distance to the HTC was 51km. Analysis of the objective measure weakly supported greater infusion frequency as a treatment-related factor for the prediction of lower adherence, however the strength of this relationship was not clinically relevant (R2=0.048). For the subjective measure, none of the explanatory variables were significant.

Conclusion

Adherence is a multifaceted construct. Despite the use of theory, most of the variance in adherence to treatment recommendations in this sample of patients with haemophilia remains unknown. Further research on other potential predictors of adherence, and possible variables and relationships within factors of the MAM is required.

Endovascular Management of Hemarthrosis in Patients with Bleeding Diatheses: Systematic Review

PURPOSE

In this systematic review, we report the safety and efficacy of embolization for treating hemarthrosis in patients with bleeding diatheses with or without a history of prior arthroplasty.

MATERIALS AND METHODS

A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. A structured search was performed in PubMed, Web of Science, MEDLINE, and SCOPUS databases of patients undergoing embolization for hemarthrosis. Demographic data, clinical history, angiographic findings, interventions, and outcomes were extracted and tabulated.

RESULTS

The search identified 97 unique titles of which 15 were deemed relevant comprising 78 patients with coagulopathies undergoing 93 embolization procedures. Mean follow-up time was 29 months (range 3-116.5). In the 29 patients who underwent arthroplasty prior to embolization for hemarthrosis, there were 11 bleeding recurrences (37.9%). Of these patients who experienced recurrences, 10 underwent repeat embolization as coagulation factor replacement was not sufficient to address the re-bleeding. In the 49 patients with bleeding diatheses who underwent embolization for hemarthrosis with no history of prior arthroplasty, there were 11 recurrences (22.4%) and 4 of these patients underwent repeat embolization with favorable results. There were four major procedure-related complications.

CONCLUSION

Transarterial embolization is safe and effective in addressing recurrent hemarthrosis in patients with bleeding diatheses with or without a history of arthroplasty of the affected joint.

Establishing an online physical exercise program for people with hemophilia

BACKGROUND

Hemophilia is a congenital bleeding disorder with an estimated frequency of 1:10,000 births. Repeated joint bleeding is a hallmark of the disorder and leads to painful hemophilic arthropathy. Regular exercise can help improve joint stability and function, reduce the risk of injury and bleeding and improve physical fitness and quality of life. This method paper describes an online training concept aiming to offer access to appropriate exercise instructions for people with hemophilia who are not able to attend regular training at a hemophilia center.

METHODS

The online exercise program is accessible through the homepage of the Department of Physical Medicine, Rehabilitation and Occupational Medicine of the Medical University Vienna as well as through scanning a QR code printed on information material using a smart phone or tablet.

RESULTS

The program contains exercises to improve mobility, coordination, muscular strength and flexibility. A brief introduction is given by a hematologist, a pediatrician and a physiatrist. An introductory video informs about contraindications and essential precautions, such as medical attendance and sufficient factor therapy to consider before starting the training. Another video gives advice on the exercise composition. The demonstrated exercises are explained by a physician and are available for adults and children. To individualize training recommendations and offer further diagnostic tools and physical treatment options as necessary, the Department of Physical Medicine, Rehabilitation and Occupational Medicine of the Medical University of Vienna will establish consultation hours for people with hemophilia.

CONCLUSION

As hemophilia is an orphan disease, patients are mainly treated in specialized centers. For patients who live far from these centers or have limited access to a training there for other reasons, the physical medicine consultation hour and the implementation of online exercise instructions offer individually adapted exercise information for a regular home-based training to benefit from increased physical fitness and joint stability.

[Pain therapy for children and adolescents with hemophilia : Recommendations by an expert panel]

BACKGROUND

Children and adolescents with severe hemophilia commonly suffer from acute and chronic pain as a consequence of hemophilia-related bleeding. Intervention-related pain also plays a major role. Despite its high prevalence in this patient group, hemophilia-related pain is not always adequately addressed and sufficiently treated.

OBJECTIVES

This paper discusses how to improve pain management for children and adolescents (0-18 years) with hemophilia and which specific features in this population should influence decisions in pain management.

MATERIALS AND METHODS

An expert panel discussed challenges in pain treatment in children and adolescents with hemophilia. Recommendations are based on evidence and clinical experience.

RESULT

Pain management in children with hemophilia needs improvement. Children with hemophilia are at risk of developing chronic pain and of suffering traumatization due to insufficient pain management. Pain therapy can be challenging in these children as both their age and the underlying disease limit the options in particular in pain medication. The expert panel developed recommendations to improve pain management in children with hemophilia.

Recommendations on multidisciplinary management of elective surgery in people with haemophilia

Planning and undertaking elective surgery in people with haemophilia (PWH) is most effective with the involvement of a specialist and experienced multidisciplinary team (MDT) at a haemophilia treatment centre. However, despite extensive best practice guidelines for surgery in PWH, there may exist a gap between guidelines and practical application. For this consensus review, an expert multidisciplinary panel comprising surgeons, haematologists, nurses, physiotherapists and a dental expert was assembled to develop practical approaches to implement the principles of multidisciplinary management of elective surgery for PWH. Careful preoperative planning is paramount for successful elective surgery, including dental examinations, physical assessment and prehabilitation, laboratory testing and the development of haemostasis and pain management plans. A coordinator may be appointed from the MDT to ensure that critical tasks are performed and milestones met to enable surgery to proceed. At all stages, the patient and their parent/caregiver, where appropriate, should be consulted to ensure that their expectations and functional goals are realistic and can be achieved. The planning phase should ensure that surgery proceeds without incident, but the surgical team should be ready to handle unanticipated events. Similarly, the broader MDT must be made aware of events in surgery that may require postoperative plans to be changed. Postoperative rehabilitation should begin soon after surgery, with attention paid to management of haemostasis and pain. Surgery in patients with inhibitors requires even more careful preparation and should only be undertaken by an MDT experienced in this area, at a specialized haemophilia treatment centre with a comprehensive care model.

Increased bone resorption in hemophilia

In patients with hemophilia, osteoporosis is frequently observed for which the etiology remains unclear. The aim of this paper is to review the available experimental evidence indicating the presence of this disorder in patients with hemophilia, explore the potential mechanisms which may lead to reduced bone mineral density (BMD) and speculate on useful interventions to circumvent it. A narrative review of the English literature up to April 2018 was performed. The available evidence demonstrates an increased rate of bone resorption and an excess of osteoporosis among patients with hemophilia. FVIII and FIX may act through at least two pathways: promoting bone formation by a thrombin-mediated mitogenic effect on osteoblasts and by cytokine-mediated osteoclast activity. Another potential indirect mechanism mediated through the RANK-RANKL pathway has been suggested but remains controversial. The role of confounders such as lack of activity and immobility must be considered.

Treatment of musculo-skeletal pain in haemophilia

Musculo-skeletal pain treatment is inadequate in many haemophilic patients. Analgesics are used only by 36% of adult patients. FVIII/FIX intravenous infusion is mainly used to lessen pain, followed in frequency by usage of NSAIDS (primarily COX-2 inhibitors). In about 30% of patients, pain continues after infusion of F VIII/IX. In acute haemarthroses pain treatment must continue until total disappearance (checked by ultrasonography) and include haematologic treatment, short-term rest of the involved joint, cryotherapy, joint aspiration and analgesic medication (paracetamol in mild pain, metamizole for more intense pain, and in a few precise patients, soft opioids such as codeine or tramadol). In the circumstance of intolerable pain we should use morphine hydrochloride either by continual infusion or a patient-controlled analgesia (PCA) pump, determined by the age, mental condition and grade of observance of the patient. Epidural blocks utilizing bupivacaine and fentanyl may be very efficacious as well. Three main strategies to alleviate chronic musculo-skeletal pain secondary to haemophilic arthropathy (joint degeneration) exist: pharmacologic management, physical medicine and rehabilitation, and intra-articular injections. As for pharmacologic management, NSAIDs (ibuprofen, diclofenac, celecoxib, robecoxib) are better than paracetamol. The advantages of tramadol or tramadol/paracetamol and non-tramadol opioids are scanty. With respect to physical medicine and rehabilitation, there is insufficient confirmation that a brace has supplementary favourable effect compared with isolated pharmacologic management. Land-based curative exercise and watery exercise have at the minimum a tiny short-run benefit. Curative ultrasound can be helpful (poor quality of evidence). The efficacy of transcutaneous electrostimulation (TENS) for pain mitigation has not been proved. Electrical stimulation treatment can procure notable ameliorations. With respect to intra-articular injections, viscosupplementation appears to be a useful method for pain alleviation in the short-run (months). The short-run (weeks) advantage of intra-articular corticosteroids in the treatment of joint pain has been shown.

Simultaneous bilateral total knee arthroplasty in hemophilia: is it recommended?

INTRODUCTION

Simultaneous bilateral total knee arthroplasty (TKA) is a potentially cost-saving manner of caring for patients with hemophilia who have bilateral symptomatic hemophilic knee arthropathy. Because factor VIII is used only once in bilateral TKA, it is performed in hemophilia to reduce costs. Areas covered: This article reviews the potential role of simultaneous bilateral TKA in patients with hemophilia. Expert commentary: Although two recent reports have mentioned the benefits of simultaneous bilateral TKA in patients with hemophilia, the data are still scant and preliminary. The two systematic reviews and the meta-analyses on bilateral TKA in patients without hemophilia have shown that there are more complications with bilateral TKA than with unilateral TKA. This article calls the potential risks of this technique to the attention of hemophilia specialists. The current use of simultaneous bilateral TKA in patients with hemophilia is unadvised, and raising false expectations in these patients should be avoided. Prospective studies in the specific field of TKA in patients with hemophilia are needed.

Side effects and potential risk factors of botulinum toxin type A intramuscular injections in knee flexion contractures of hemophiliacs

INTRODUCTION

Knee flexion contracture (KFC) is a common complication of recurrent hemarthrosis in children and young adults with hemophilia. If the KFC is not prevented (by means of primary prophylaxis) and treated properly and early (be means of physical medicine and rehabilitation), it will become fixed. Areas covered: The aim of this article is to review the potential role of botulinum toxin type A (BTX-A) intramuscular injections for the treatment of KFC in people with hemophilia (PWH). Expert commentary: Although two recent reports have mentioned the benefits of intramuscular injections of BTX-A in PWH with KFC, the data are still scant and too preliminary. The use of intramuscular injections of BTX-A in PWH today should not be recommended until more case studies/small series (ideally well-designed clinical trials) fully demonstrate that this is safe and effective. The risks of intramuscular injections to a hemophilia patient cannot be underestimated (iatrogenic muscle hematomas and pseudotumors). This paper calls the attention of hemophilia treaters on the potential risks of this apparently interesting technique. The current use of BTX-A intramuscular injections in KFC of PWH could make no sense. Raising false expectations in these patients should be avoided.

The Health Assessment Questionnaire Disability Index (HAQ-DI) as a valid alternative for measuring the functional capacity of people with haemophilia

BACKGROUND

There are several scales for evaluating the functional capacity of people with haemophilia (PWH).

OBJECTIVE

To demonstrate the value and simplicity of the "Health Assessment Questionnaire Disability Index" (HAQ-DI) for making a functional assessment of PWH in those contexts in which the specific physical assessment scales cannot be used [Functional Independence Score in Haemophilia (FISH) and Haemophilia Activities List (HAL)]. The HAQ-DI is a validated generic self-administered questionnaire that is completed in <5min.

METHODS

Data was collected on the physical and functional status of 62 adult PWH having haemophilia. Their average age was 34.7 years. The impairment of the PWH was assessed using the generic self-administrable functionality questionnaire (HAQ-DI) and the following scales: The "World Federation of Haemophilia Physical Examination Score" (WFH-PES) and the Haemophilia Joint Health Score 2.1 (HJHS 2.1). We evaluated the correlation between generic HAQ-DI score and physical assessment scores WFH-PES, HJHS 2.1 (correlation analysis).

RESULTS

The correlation between WFH-PES and HAQ-DI showed a Spearman's correlation coefficient of r=0.804 (p<0.05). The correlation between HJHS 2.1 and HAQ-DI showed a Spearman's correlation coefficient of r=0.823 (p<0.05). A positive and fairly strong correlation was found between them.

CONCLUSIONS

The presented associations established the application of HAQ-DI as a PROXY clinical indicator of functional status. HAQ-DI is a valid alternative for assessing functional capacity in adult PWH, especially in cases in which, for some reason, it is not possible to use other tools that are specific for haemophilia. Clinical practice needs a less time demanding assessment tools.

Pain and pain management in haemophilia

Joint pain is common in haemophilia and may be acute or chronic. Effective pain management in haemophilia is essential to reduce the burden that pain imposes on patients. However, the choice of appropriate pain-relieving measures is challenging, as there is a complex interplay of factors affecting pain perception. This can manifest as differences in patients’ experiences and response to pain, which require an individualized approach to pain management. Prophylaxis with factor replacement reduces the likelihood of bleeds and bleed-related pain, whereas on-demand therapy ensures rapid bleed resolution and pain relief. Although use of replacement or bypassing therapy is often the first intervention for pain, additional pain relief strategies may be required. There is an array of analgesic options, but consideration should be paid to the adverse effects of each class. Nevertheless, a combination of medications that act at different points in the pain pathway may be beneficial. Nonpharmacological measures may also help patients and include active coping strategies; rest, ice, compression, and elevation; complementary therapies; and physiotherapy. Joint aspiration may also reduce acute joint pain, and joint steroid injections may alleviate chronic pain. In the longer term, increasing use of prophylaxis or performing surgery may be necessary to reduce the burden of pain caused by the degenerative effects of repeated bleeds. Whichever treatment option is chosen, it is important to monitor pain and adjust patient management accordingly. Beyond specific pain management approaches, ongoing collaboration between multidisciplinary teams, which should include physiotherapists and pain specialists, may improve outcomes for patients.

Coexistence of Factor VII Deficiency and Hereditary Spastic Paraplegia in Two Siblings

We present the case of two patients aged 12 years and 7 years who were referred to our hospital for factor VII deficiency inherited in an autosomal recessive pattern, who had suffered from previous multiple joint haemarthroses. They presented with fine motor symptoms and difficulty in walking. During physical examination we observed neurological symptoms (general hypotonia, muscular hypotrophy, exaggerated tendon reflexes, pes cavus, and spastic gait). Given that the symptoms were not justified by the deficiency of coagulation factor VII and on suspicion of hereditary spastic paraplegia (HSP), tests were carried out. Findings from the tests confirmed the diagnosis of HSP (axonal degeneration of the central motor pathway and pyramidal tracts), further complicated by mixed neuropathy. This disease was also inherited in an autosomal recessive pattern with no direct genetic association with factor VII deficiency. Neurological symptoms had gone unnoticed due to a history of multiple joint haemarthrosis; musculoskeletal examination led to a satisfactory differential diagnosis. Haematological prophylaxis was commenced with rFVIIa at 30 mcg/kg, three days per week. A rehabilitation programme was prescribed so that the patient could remain independent for as long as possible, based on orthosis, physiotherapy, and occupational therapy. Response to treatment is currently satisfactory and no new bleeding has presented. As far as we are aware, the coexistence of these two diseases (factor VII deficiency and HSP) has not been previously reported in the literature.

Exercise for haemophilia

BACKGROUND

Haemophilia is a bleeding disorder associated with haemorrhaging into joints and muscles. Exercise is often used to aid recovery after bleeds, and to improve joint function in the presence of arthropathy.

OBJECTIVES

Our objective was to systematically review the available evidence on the safety and effectiveness of exercise for people with haemophilia.

SEARCH METHODS

We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register and electronic databases PubMed, OVID-Embase, and CINAHL. We hand searched abstracts from congresses of the World Federation of Hemophilia and the European Hematology Association, trial registries and the reference lists of relevant articles.Date of the last search of the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register: 14 December 2016.

SELECTION CRITERIA

Randomized or quasi-randomized controlled studies comparing any exercise intervention considered relevant in haemophilia management including supervised, unsupervised, aquatic, strengthening, aerobic or cardiovascular, stretching, proprioceptive and balance training exercise programs in males of any age with haemophilia A or B of any severity (those with co-morbidities were not excluded).

DATA COLLECTION AND ANALYSIS

Two authors reviewed the identified abstracts to determine their eligibility. For studies meeting the inclusion criteria, full articles were obtained. The two authors extracted data and assessed the risk of bias. Any disagreements were resolved by discussion. The authors contacted study investigators to obtain any missing data.

MAIN RESULTS

Eight studies were included, which represented 233 males with all severities of haemophilia A and B, ranging in age from eight years to 49 years. Study duration ranged from four to 12 weeks. Exercise interventions varied greatly and included resistance exercises, isometric exercises, bicycle ergometry, treadmill walking and hydrotherapy; therefore, comparison between studies was difficult.None of the studies measured or reported adverse effects from the interventions. None of the studies reported outcomes regarding bleed frequency, quality of life or aerobic activity. Overall risk of bias across all studies was assessed as unclear.Very few studies provided sufficient information for comparison. None of the studies reported data that favoured the control group. One study reported that six weeks of resistance training improved joint health status (Colorado score) compared to controls. The addition of pulsed electromagnetic fields also improved ankle scores compared to exercises alone, but this was not seen in the elbows or knees.Two studies reported statistically significant improvements in pain intensity after exercise interventions compared to controls. Hydrotherapy exercises produced significant decreases in pain compared to controls and land-based exercise groups.Two studies found improvement in joint motion in the exercise group compared to controls. One study compared land- and water-based exercises; there was no difference in the range of motion between the two groups; however, the water-based exercise group did show improvement over the control group.One study, comparing joint traction and proprioceptive neuromuscular facilitation for the elbow to a control group, showed no differences in biceps girth or strength after 12 weeks of intervention.Some studies reported comparisons between interventions. In one study, treadmill training significantly improved balance in children compared to bicycle ergometry. Another study added partial weight bearing exercises to quadriceps exercises and showed improved walking tolerance.Four studies evaluated quadriceps or hamstring strength (or both). The addition of bicycle ergometry and exercises with weights was more effective than static exercises and treadmill walking for strengthening knee flexors and extensors. Partial weight-bearing exercises through range were more effective than static and short arc exercises for improving knee extensor strength. The addition of treadmill walking to ultrasound, stretching and strengthening exercises showed increased peak torque of knee flexors and extensors and decrease in knee effusion.The results should be interpreted with caution due to the quality of evidence (GRADE) as outlined in the summary of findings tables, which demonstrates that all but one of the outcomes assessed were rated as low or very low due to the small sample sizes and potential bias.

AUTHORS' CONCLUSIONS

These results must be considered with caution. There is a lack of confidence in the results due to the small number of included studies and the inability to pool the results due to the heterogeneity of outcome measures. Most exercise interventions produced improvement in one or more of the measured outcomes including pain, range of motion, strength and walking tolerance. Hydrotherapy may be more effective than land exercises for pain relief in adults. Functional exercises such as treadmill walking and partial weight bearing exercises seem to be more effective than static or short arc exercises for improving muscle strength. These findings are consistent with the many non-controlled intervention reports in the haemophilia literature. No adverse effects were reported as a result of any of the interventions. However, some groups used prophylactic factor prior to exercise and other groups studied only subjects with moderate haemophilia. Therefore, the safety of these techniques for persons with severe haemophilia remains unclear.

Orthopedic disorders of the knee in hemophilia: A current concept review

The knee is frequently affected by severe orthopedic changes known as hemophilic arthropathy (HA) in patients with deficiency of coagulation factor VIII or IX and thus this manuscript seeks to present a current perspective of the role of the orthopedic surgeon in the management of these problems. Lifelong factor replacement therapy (FRT) is optimal to prevent HA, however adherence to this regerous treatment is challenging leading to breakthrough bleeding. In patients with chronic hemophilic synovitis, the prelude to HA, radiosynovectomy (RS) is the optimal to ameliorate bleeding. Surgery in people with hemophilia (PWH) is associated with a high risk of bleeding and infection, and must be performed with FRT. A coordinated effort including orthopedic surgeons, hematologists, physical medicine and rehabilitation physicians, physiotherapists and other team members is key to optimal outcomes. Ideally, orthopedic procedures should be performed in specialized hospitals with experienced teams. Until we are able to prevent orthopedic problems of the knee in PWH will have to continue performing orthopedic procedures (arthrocentesis, RS, arthroscopic synovectomy, hamstring release, arthroscopic debridement, alignment osteotomy, and total knee arthroplasty). By using the aforementioned procedures, the quality of life of PWH will be improved.

Strategies to encourage physical activity in patients with hemophilia to improve quality of life

Hemophilia is a bleeding disorder caused by a congenital abnormality of blood coagulation. Until the mid-1970s, patients with hemophilia (PWH) were advised to refrain from physical activity (PA) because of a perceived increased risk of bleeding. Since then, PA, which is recognized as being essential for health maintenance, is now recommended by the World Federation of Hemophilia. Moreover, a number of studies reported that PA can improve treatment efficacy and prevent bleeding in PWH. Physical assessment and intervention in PA are currently used in clinical practice. However, the necessity of PA is not emphasized, and many PWH generally have low- to- no PA. Therefore, a behavior change approach to encourage patient motivation is becoming ever more important. In this article, we review articles addressing PA in PWH and discuss strategies to encourage PA through a behavior change approach by focusing on factors relevant to hemophilia, such as benefits and bleeding risk of PA, risk management of bleeding, PA characteristics, and difficulty with exercise adherence. The trust relationship between clinicians and patients, a transtheoretical model of behavior change, and motivation theory as approaches to promote PA are introduced. Finally, we review a case report of the clinical success of a behavior change approach to promote PA. Many PWH find it difficult to continue PA because of aging, fear of bleeding, insufficient recognition of PA benefits, and psychological problems. Therefore, it is essential and important to perform prophylaxis with PWH and to heighten their understanding of the benefits and risks of PA, before initiating the exercise regimen. For those patients who find it difficult to participate in PA, it is necessary to plan individual-based behavior change approach and encourage self-efficacy.

Haemophilic synovitis of the elbow: radiosynovectomy, open synovectomy or arthroscopic synovectomy?

Arthroscopic synovectomy (AS) of the elbow, while providing similar pain relief to open synovectomy (OS), may place patients at higher risk for recurrence. The primary predictor of outcome is degree of pre-existing degenerative changes within the joint. Regarding haemophilia patients, radiosynovectomy (RS) is the best choice for patients with persistent synovitis of the elbow. In the elbow we recommend a dose of 30-40 megabecquerels (mBq) in children and a dose of 56-74 mBq in adults. If three consecutive RSs with 6 months intervals are ineffective, an AS or OS must be indicated. Synovectomy (by any method) significantly reduces bleeding episodes. Although the dose of radiation of RS is minimal, 0.32 millisieverts (mSv) in children, 0.54 mSv in adults, and neither articular nor systemic neoplastic changes related to RS have been reported so far, all patients must be given opportunity to consider risk/benefit ratios. Radiation dose due to natural sources is 2 mSv per year and the recommended limit for patients (apart from natural sources is 1 mSv per year). My current recommendation is to use RS in children older than 12 years of age. Therefore, in children younger than 12 years of age an AS should be indicated. OS should be reserved for adults requiring radial head excision (due to a severe limitation of pronation-supination) and synovectomy in the same surgical session.
