Functional Independence Score in Haemophilia: a new performance-based instrument to measure disability

Anesthetic considerations for joint replacement surgery in hemophilic arthropathy: a comprehensive review

Managing hemophilia in patients undergoing joint replacement surgery requires a comprehensive approach encompassing preoperative assessment, meticulous intraoperative care, and tailored postoperative management. Evaluation of joint integrity, bleeding history, and inhibitor presence guides surgical planning and hemostatic therapy selection to optimize outcomes. During surgery, careful attention to factor replacement, antibiotic prophylaxis, anesthetic techniques, and orthopedic strategies minimizes bleeding risk and enhances surgical success. Postoperatively, effective pain management, continued hemostatic therapy, and individualized rehabilitation programs are vital for facilitating recovery and preventing complications. Close monitoring for potential complications, such as periprosthetic joint infection and recurrent hemarthrosis, allows for prompt intervention when necessary. Overall, a collaborative approach involving hematologists, orthopedic surgeons, anesthesiologists, and rehabilitation specialists ensures comprehensive care tailored to the unique needs of patients with hemophilia undergoing joint replacement surgery, ultimately optimizing outcomes and improving quality of life. This holistic approach addresses the multifaceted challenges posed by hemophilia and joint replacement surgery, providing patients with the best possible chance for successful outcomes and long-term joint function. By integrating specialized expertise from multiple disciplines and implementing evidence-based strategies, healthcare providers can effectively manage hemophilia in the context of joint replacement surgery, mitigating risks and maximizing benefits for patients.

Promoting pain coping skills in haemophilia: A remote intervention integrating exercise and pain education

BACKGROUND

Chronic joint pain is a significant and widespread symptom in people with haemophilia (PWH). Despite medical advancements, effective pain management remains challenging.

AIM

This study presents an innovative approach that integrates remote physical exercises, pain neuroscience education, and coping strategies to address chronic pain in PWH.

METHODS

The remote intervention consisted of sixteen 5-min videos encompassing physical exercises for chronic pain management and pain education strategies. These videos formed an 8-week remote intervention program. Clinical and physical assessments were conducted before and after the intervention.

RESULTS

A total of thirty-one PWHs, with a median age of 34 years (ranging from 16 to 59 years), completed the remote intervention. The study revealed significant improvements in pain intensity, disability, and physical performance among PWH with chronic pain. Enhanced functional capacity was evident in the Timed Up and Go and Single Leg Stance tests, accompanied by improved scores on the Functional Independence Score in Haemophilia (FISH). Although lacking a control group, our findings are consistent with other successful exercise and pain education programs.

CONCLUSIONS

This innovative intervention holds promise for managing chronic pain in PWH, underscoring patient empowerment, education, and collaboration. Notably, our study stands out by uniquely combining pain education and coping strategies, bolstering evidence for effective pain management.

Reliability and construct validity of the ACTIVLIM-Hemo and Haemophilia Activities List (HAL) questionnaires in individuals with haemophilia

OBJECTIVE

The objective of this study is to assess the reliability and construct validity of ACTIVLIM-Hemo, a newly developed Rasch-built questionnaire designed to evaluate activity limitations in people with haemophilia (PwH), in comparison with the Haemophilia Activities List (HAL), which was developed using Classical Test Theory.

METHODS

A total of 130 participants with haemophilia A or B were included. They underwent various assessments, including joint health scoring (HJHS), functional tests (TUG and 2MWT) and completed questionnaires such as the BPI, IPAQ, HAL and ACTIVLIM-Hemo. Reliability indices and the minimum detectable change (MDC95) were determined for ACTIVLIM-Hemo and for HAL. Construct validity was evaluated through correlations and multiple linear regression, considering demographic and clinical factors.

RESULTS

Both ACTIVLIM-Hemo (Person Separation Index = 0.92) and HAL (Cronbach's α = 0.98) demonstrated high reliability. The MDC95 for ACTIVLIM-Hemo represented 11.6% of its measurement range, while for HAL, it amounted to 18/100 score points. Activity limitations measured by both instruments were significantly correlated with demographic and clinical factors. Joint health (HJHS), pain severity (BPI) and walking performance (2MWT) emerged as the main predictors of activity limitations, explaining 75% of the variance in ACTIVLIM-Hemo and 60% in HAL.

CONCLUSION

ACTIVLIM-Hemo stands as a reliable and valid instrument for assessing activity limitations in PwH. Both instruments exhibited significant correlations with demographic and clinical factors, but ACTIVLIM-Hemo displayed a more homogeneous construct. Given its linear scale and lower MDC95 and better targeting, ACTIVLIM-Hemo shows promise as a patient-centric instrument for assessing responsiveness to treatment during individual follow-up.

Occupational therapy in the management of haemophilia patients: A scoping review

BACKGROUND

Haemophilia is a haematological disease, although most haemorrhages occur in the locomotor system. Patients are physically disabled from an early age and have a poorer perception of quality of life. In the day-to-day lives of patients and their families, psychosocial well-being, the disease's physical, personal, and social impact, as well as work-related problems are the most complicated aspects of the disease that need to be addressed.

OBJECTIVE

To identify the role of occupational therapy in managing patients with haemophilia and to analyse the therapeutic potential of occupational therapy in treating these patients.

METHODS

A scoping review was conducted to identify the role of occupational therapy in managing patients with haemophilia and to analyse the therapeutic potential of occupational therapy in treating these patients. The review was registered in the international registry PROSPERO (Id: CRD42022319637). The databases consulted were SCOPUS, PubMed, PsycINFO, Web of Science and Science Direct, including all studies published until 14 August 2023.

RESULTS

No single study was found that specifically developed an occupational therapy intervention for patients with haemophilia. Measurement instruments have been identified, specific for patients with haemophilia and generic, that can be useful for the functional evaluation of these patients in the occupational therapy approach. Different studies showed the importance of multidisciplinary treatment, including occupational therapy.

CONCLUSIONS

The use of occupational therapy could be effective in improving autonomy and quality of life in haemophilia patients. Therefore, it is of paramount importance to conduct research studies within the field of occupational therapy.

Physical therapy for end-stage hemophilic arthropathy: a case report

This report introduces a young adult who has been in bed for more than ten years with end-stage hemophilic arthropathy. He didn't have access to factor VIII (FVIII) in the early stage of hemophilia due to the high costs of clotting replacement therapy. As a result, he is experiencing some difficulties, such as joint contracture, muscular atrophy, severe pain, and poor function of cardiopulmonary. He came to visit us for a comprehensive rehabilitation program, and, finally, he achieved the basic goal of self-care in daily life.

Identifying performance-based outcome measures of physical function in people with haemophilia (IPOP)

INTRODUCTION

Recent recommendations of core outcome sets for haemophilia highlight the need for including measures of performance-based physical health and physical function sustainability. To date, there is no consensus on what outcomes might be of value to clinicians and patients.

AIM

To identify instruments of performance-based physical function to monitor musculoskeletal health in people with haemophilia that are practical in the clinical setting.

METHODS

Utilising components from the Activities and Participation Category of the WHO International Classification of Functioning (WHO-ICF), a consensus-based, decision analysis approach was used to: identify activities people with haemophilia have most difficulty performing; identify quantitative performance-based measures of identified activities via a scoping review; and obtain views on acceptability of the tests utilising a DELPHI approach.

RESULTS

Eleven activities were identified: maintaining a standing position, walking long distances, walking up and down stairs, walking on different surfaces, running, hopping, jumping, squatting, kneeling, undertaking a complex lower limb task, undertaking a complex upper limb task. Following a 2-round DELPHI survey of international physiotherapists, the 6-min walk test, timed up and down stairs, 30-s sit to stand, single leg stance, tandem stance, single hop for distance (children only) and timed up and go (adults only) reached consensus.

CONCLUSION

This study is the first step in defining a core set of performance-based instruments to monitor physical health and sustainability of physical function outcomes in people with haemophilia. Establishing the psychometric properties of the instruments and whether they are meaningful to people with haemophilia is essential.

Effectiveness of kinesiologic taping on function and pain in patients with hemophilia A

Background

Hemophilic arthropathy frequently results in musculoskeletal adjustments that impair functional capacity.

Aim

We investigated the effects of kinesiologic taping on patients with hemophilic arthropathy in this study.

Materials and Methods

Twenty-six patients were enrolled. Thirteen patients formed the Kinesiologic taping group (KT) and received the interventional protocol consisting of three kinesiologic taping sessions during three weeks; and 13 patients formed the control group (CG) and made three weeks of home exercises. All patients were evaluated using the Functional Independence Score in Hemophilia (FISH), Hemophilia Joint Health Score (HJHS), and Visual Analog Scale (VAS) at baseline, one week, and three weeks.

Results

The mean scores for the VAS, HJSS, and FISH differed significantly before and after 3 weeks in both groups (P < 0.001). However, the differences in medians after the treatment were significantly greater in the KT group than in the CG group (P < 0.001).

Conclusions

Kinesiologic taping was associated with physical improvement in hemophilia patients; however, also kinesiologic taping led to significant improvement in VAS scores.

Osteoporosis and associated risk factors in patients with severe hemophilia A: a case-control study from China

INTRODUCTION

People with hemophilia risk osteoporosis more than healthy people, which may be related to specific factors.

METHODS

This case-control study included 53 patients with severe hemophilia type A and 49 healthy participants. Dual-energy X-ray absorptiometry (DXA) was used to determine bone mineral density (BMD). Collected information on age, body mass index (BMI), number of joint arthropathies, functional independence score in hemophilia (FISH), bone turnover markers, antibodies, treatment modalities. Identified independent risk factors for osteoporosis.

RESULTS

The BMD of the femoral neck (0.80 g/cm2vs.0.97 g/cm2), ward's triangle (0.62 g/cm2vs.0.83 g/cm2), tuberosity (0.63 g/cm2vs.0.80 g/cm2) and hip (0.80 g/cm2vs.0.98 g/ cm2) in the case group were significantly lower than those in the control group, all of which were P < 0.001. However, there was no significant difference in the overall BMD of lumbar spine(L1-L4) (1.07 g / cm2vs. 1.11 g / cm2). The frequency of osteoporosis in the case group was 41.51%. BMI and FISH score were considered as independent risk factors for BMD decrease.

CONCLUSION

The BMD of patients with severe hemophilia A is much lower than that of healthy population, and this difference is mainly reflected in the hip. The clear influencing factors were low BMI and functional independence decrease. Osteoclast was active while osteoblast activity was not enhanced synchronously, which may be the pathological mechanism of BMD decrease.

Hemophilia Joint Health Score, Functional Independence Score in Hemophilia, and Pettersson Score in Pediatric Patients With Severe Hemophilia A

Hemophilia is an X-linked recessive disorder. Children with hemophilia go through spontaneous and trauma-provoked bleeding. Recurring joint bleeds lead to ongoing incapacity. Achieving healthy joints is the primary target of hemophilia management. The current study objective was to assess hemophilic joints in individuals with hemophilic arthropathy clinically, radiographically, and functionally. This cross-sectional study included 50 children with severe hemophilia A who were selected from the pediatric hematology clinic. All children were assessed for Hemophilia Joint Health Score (HJHS). Joint assessed functionally by Functional Independence Score in Hemophilia (FISH) and radiologically by plain radiograph and scored by the Pettersson scoring system. Data were analyzed using Statistical Package for Social Sciences. The mean age of the studied cases of hemophilia was 8.5±3.1 years. The mean FISH score among the studied patients was 26.8±4.2, the mean HJHS was 16.8±12.8, and the Pettersson score was 4.9±2.7. The number of affected joints showed a significant negative correlation to the FISH score and a significant positive correlation to HJHS. The frequency of hemarthrosis/month showed a significant positive correlation to HJHS. The number of affected joints showed a significant negative correlation to the FISH score and a significant positive correlation to HJHS. Frequency of hemarthrosis/month showed a significant positive correlation to HJHS.

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.

[Analysis of the effects of low/intermediate dose of coagulation factor Ⅷ on 30 adult patients with severe hemophilia A in a single center]

Objective: To evaluate the clinical effects of low- and intermediate-dose factor Ⅷ (F Ⅷ) prophylaxis in Chinese adult patients with severe hemophilia A. Methods: Thirty adult patients with severe hemophilia A who received low- (n=20) /intermediate-dose (n=10) F Ⅷ prophylaxis at Nanjing Drum Tower Hospital affiliated with Nanjing University Medical College were included in the study. The annual bleeding rate (ABR), annual joint bleeding rate (AJBR), number of target joints, functional independence score of hemophilia (FISH), quality of life score, and health status score (SF-36) before and after preventive treatment were retrospectively analyzed and compared. Results: The median follow-up was 48 months. Compared with on-demand treatment, low- and intermediate-dose prophylaxis significantly reduced ABR, AJBR, and the number of target joints (P<0.05) ; the improvement in the intermediate-dose prophylaxis group was better than that in the low-dose prophylaxis group (P<0.05). Compared with on-demand treatment, the FISH score, quality of life score, and SF-36 score significantly improved in both groups (P<0.05), but there was no significant difference between the two groups (P>0.05) . Conclusion: In Chinese adults with severe hemophilia A, low- and intermediate-dose prophylaxis can significantly reduce bleeding frequency, delay the progression of joint lesions, and improve the quality of life of patients as compared with on-demand treatment. The improvement in clinical bleeding was better with intermediate-dose prophylaxis than low-dose prophylaxis.

ACTIVLIM-Hemo: A new self-reported, unidimensional and linear measure of activity limitations in persons with haemophilia

INTRODUCTION

To assess activity limitations in people with haemophilia (PwH), the self-reported Haemophilia Activity List (HAL) is widely employed, despite several methodological limitations impacting the interpretation of categorical scores. Modern psychometric approaches avoid these limitations by using a probabilistic model, such as the Rasch model. The ACTIVLIM is a Rasch-built measurement of activity limitations previously validated in several clinical conditions like neuromuscular disorders.

AIMS

This study sought to develop the ACTIVLIM-Hemo, meaning an ACTIVLIM scale version specifically adapted to assess daily activity limitations in adult PwH.

METHODS

Daily activities were assessed as "impossible," "difficult" or "easy" by 114 PwH (median age of 44 years) with 63 of them reassessed after 12 days. The Rasch Rating Scale model was used to identify activities delineating a unidimensional and linear scale unbiased by demographic and clinical status. Concurrent validity was determined through correlation with the HAL sub-scores and sum score.

RESULTS

The ACTIVLIM-Hemo included 22 pertinent activities, with difficulties independent of demographic and clinical conditions, allowing a reliable measure of activity limitations (PSI = .92) expressed on a linear and unidimensional scale in PwH (7%-100 % range, ceiling effect of 1/114) with excellent test-retest reliability (ICC = .978). Spearman rank correlations between ACTIVLIM-Hemo and HAL sub-scores ranged between .623 and .869.

CONCLUSIONS

The ACTIVLIM-Hemo is an easy-to-administer, valid and reliable alternative to HAL in assessing activity limitations in PwH. Its invariant scale can be used across conditions and time to compare the functional status of PwH over a wide measurement range.

Hemophilic Arthropathy: Barriers to Early Diagnosis and Management

Hemophilia is a congenital coagulopathy characterized by a deficiency of one of the clotting factors. It is characterized by the development of hematomas and hemarthrosis, either spontaneously or after minor trauma. The recurrence of hemarthroses leads to progressive and degenerative joint damage from childhood (hemophilic arthropathy). This arthropathy is characterized by disabling physical effects that limit the functionality and quality of life of these patients. Medical progress achieved over the last decade in the drug treatment of hemophilia has improved the medium and long-term prospects of patients with more effective and long-lasting drugs. The universal use of safer, more effective and prolonged prophylactic treatments may promote the prevention of bleeding, and also therefore, of the development of hemarthrosis and joint damage. A number of imaging instruments have been developed for the assessment of hemarthrosis and hemophilic arthropathy, using ultrasound, magnetic resonance imaging and simple radiology. Different physical examination scores and questionnaires allow the assessment of joint health, self-perceived activity and functionality of patients with hemophilia. The approach to these patients should be interdisciplinary. Assessment of the processes that affect pain in these patients and the development of pain education models should be implemented. Expert advice and information to patients with hemophilia should be based on individual functional prevention diagnoses, advice on available therapies and sports practice, as well as health recommendations.

The Limitations and Unmet Needs of the Five Cornerstones to Guarantee Lifelong Optimization of Prophylaxis in Hemophilia Patients

Prophylaxis to prevent bleeding is highly recommended for hemophilia patients. The development of new drugs and tools for modeling personalized prophylaxis provides the means for people with hemophilia to lead active lives with a quality of life comparable to that of nonhemophilic individuals. The choice of regimens must be made on a highly individual basis. Unfortunately, reference guides neither always concur in their recommendations nor provide directions to cover all possible scenarios. In this review, a group of experts identify the significant limitations and unmet needs of prophylaxis, taking advantage of their clinical experience in the disease, and supported by a rigorous literature update. To perform a more systematic and comprehensive search for gaps, the main cornerstones that influence decisions regarding prophylactic patterns were first identified.

Bleeding phenotype, joint status, physical activity, pharmacokinetics/medication properties, and adherence to treatment were considered as the primary mainstays that should allow physicians guiding prophylaxis to secure the best outcomes. Several challenges identified within each of these topics require urgent attention and agreement. The scores to assess severity of bleeding are not reliable, and lead to no consensus definition of severe bleeding phenotype. The joint status is to be redefined in light of new, more efficient treatments with an agreement to establish one scale as the unique reference for joint health. Further discussion is needed to establish the appropriateness of high-intensity physical activities according to patient profiles, especially because sustaining trough factor levels within the safe range is not always warranted for long periods. Importantly, many physicians do not benefit from the advantages provided by the programs based on population pharmacokinetic models to guide individualized prophylaxis through more efficient and cost-saving strategies. Finally, ensuring correct adherence to long-term treatments may be time-consuming for practitioners, who often have to encourage patients and review complex questionnaires.

In summary, we identify five cornerstones that influence prophylaxis and discuss the main conflicting concerns that challenge the proper long-term management of hemophilia. A consensus exercise is warranted to provide reliable guidelines and maximize benefit from recently developed tools that should notably improve patients' quality of life.

The effects of close kinetic chain exercises on proprioception and physical activity level in pediatric patients with hemophilia

INTRODUCTION

Knee joint proprioception is affected, and lower extremity functioning declines over time in patients with hemophilia A.

AIM

To investigate the effects of a structured exercise programme consisting of the close kinetic chain (CKC) exercises on proprioception and physical activity level in pediatric patients with hemophilia.

METHODS

A total of 21 patients with hemophilia A who had at least one target knee joint were randomized into three groups: Study Group (SG, n = 7), Conventional Treatment Group (CTG, n = 7) and Control Group (CG, n = 7). The SG received a structured, lower limb-specific exercise protocol consisting of CKC exercises 2 days a week for 12 weeks, in addition to prophylactic treatment. The CTG received exercise training as described in the published literature. The CG continued to receive prophylactic treatment during the study period. Proprioception was measured using a digital goniometer before and after treatment in open and closed kinetic chain positions (CKCPs). The Five Times Sit to Stand (STS), Timed Up and Go (TUG) and Functional Independence Score in Hemophilia were used for the assessment of physical activity level.

RESULTS

A significant pre/post-treatment difference was found among the groups in proprioception (p = .001) and physical activity level (TUG p = .008, STS p = .001, FISH p = .006). Improvements in proprioception and physical activity level were greater in the SG compared to the other two groups (p < .05).

CONCLUSION

Compared to conventional exercise, the structured exercise protocol consisting of CKC exercise training produced improvements in proprioception and physical activity in patients with hemophilia A.

Clinical profile and demographic characteristics of moderate and severe hemophilia patients in a tertiary care hospital of Bangladesh

BACKGROUND

Hemophilia is one of the commonest inherited bleeding disorders which may lead to chronic bleeding tendencies and life-long disabilities if not properly managed. Knowing the pattern of the disease aids in the prevention of disability and improvement of quality of life in hemophilia. However, there is a dearth of literature on the issue in Bangladesh. So, this study was designed to explore the frequency and site of spontaneous bleeding in moderate and severe hemophilia patients visiting in a tertiary level hospital.

METHODS

This descriptive cross-sectional study was conducted at the department of Hematology and Bone Marrow Transplantation (BMT) Center in Dhaka Medical College Hospital, Dhaka between February 2020 and August 2020. A total of 44 diagnosed cases of moderate to severe hemophilia were included in the study according to inclusion criteria. A detailed inquiry of history, thorough physical examination and relevant investigations were done and were recorded in case-record form. Informed written consent was taken from patients or their guardians where appropriate. All procedures were done according to Declaration of Helsinki. After entry and checking, data was analysed using SPSS version 26.

RESULTS

Out of 44 participants, 25 (56.8%) and 19 (43.2%) had moderate and severe hemophilia. Mean age of the study population was 21.31 (± 9.78) years with the majority aged between 11 and 20 years (45.5%). All sociodemographic features were similar across severity. Hemophilia A and B was found in 90.9% and 9.1%, respectively. However, all type B patients severe hemophilia making it statistically significantly different from type A (p = 0.029). The median age of first bleeding was 3.5 years and median age of first diagnosis was 5 years. Nevertheless, approximately 67.4% patients were diagnosed as a case of hemophilia at the time of their first diagnosis. The median spontaneous bleedings episodes among all patients was 32 (range: 0-97) which did not different significantly between severe and moderate patients. The most common affected (target) joint was knee joint (88.6%) followed by elbow joint (64%) among all patients. The knee joint was more commonly involved in severe than moderate disease.

CONCLUSION

This study observed the variations in pattern and frequency of spontaneous bleeding in patients with hemophilia. Severe disease was more frequent in hemophilia B than A and knee joint was the most frequent site of bleeding. However, further extensive studies are recommended.

Low dose prophylaxis and antifibrinolytics: Options to consider with proven benefits for persons with haemophilia

INTRODUCTION

Prophylaxis has become standard of care for persons with severe phenotype haemophilia (PWsH). However, 'standard prophylaxis' with either factor or non-factor therapies (emicizumab) is prohibitively expensive for much of the world. We sought to evaluate whether haemophilia care can be provided at a lower cost yet achieve good results using Lower dose/Lower frequency prophylaxis (LDP) and with increasing use of antifibrinolytics (Tranexamic acid and Epsilon amino caproic acid).

METHODS

We identified 12 studies that collectively included 335 PWsH using LDP. Additionally, we undertook a literature search regarding the benefits of antifibrinolytics in haemophilia care.

RESULTS

Identified studies show that LDP is far superior to no prophylaxis (On demand [OD] therapy) resulting in significant patient benefits. Patients on LDP showed (in comparison to patients OD) on average: 72% less total bleeds; 75% less joint bleeds; 91% less days lost from school; 77% less hospital admission days; and improved quality of life measures. These benefits come at similar or only slightly higher (< 2-fold greater) costs than OD therapy. Antifibrinolytics are effective adjunctive agents in managing bleeds (oral, nasal, intracranial, possibly other) and providing haemostasis for surgeries (particularly oral surgeries). Antifibrinolytics can substitute for more expensive factor concentrates or can reduce the use of such concentrates. There is evidence to show that antifibrinolytics may be used in conjunction with factor concentrates/emicizumab for more effective/less costly prophylaxis.

CONCLUSIONS

The use of LDP along with appropriate and increased use of antifibrinolytics offers less resourced countries good options for managing patients with haemophilia.

Twice Weekly Vs. Thrice Weekly Low-Dose Prophylactic Factor VIII Therapy in Children with Hemophilia A: An Open Label Randomized Trial

INTRODUCTION

Low dose factor VIII prophylactic therapy in hemophilia has not been well established till date. This randomized controlled trial compared the efficacy of twice vs. thrice weekly schedule of low dose prophylactic factor VIII in children with hemophilia A as evaluated by the bleeding rate and clinico-radiological evaluation.

METHODS

Thirty-three children with severe hemophilia A (≤18 years) were randomized into two groups. Baseline evaluation included detailed history, clinical (HJHS 2.1 score and FISH score) and radiological examination (Pettersson score and ultrasound score). Group 1 received twice weekly factor VIII prophylaxis while group 2 received thrice weekly factor VIII prophylaxis, the dose being 10 U/kg in both groups. All participants were followed up over next 6 months to one year. Data regarding acute bleeding episodes and repeat clinico-radiological assessment at the end of follow up were recorded.

RESULTS

We analyzed 14 children in twice weekly prophylaxis group and 16 children in thrice weekly prophylaxis group. Statistically insignificant difference was found between the bleeding rates in both the groups after prophylaxis with the median values of monthly bleeding rate being 0.17 and p-value of 0.79. The differences between the initial and final clinical and radiological scores within each group were found to be statistically significant. There was no significant difference in the clinical and radiological scores in between the groups.

CONCLUSION

Twice weekly FVIII therapy is effective, easily administered prophylactic schedule to prevent long-term complications of hemophilia A. Lay summaryHemophilia A is one of the most common congenital coagulation factor deficiencies. Low dose factor VIII prophylaxis is recommended for hemophilia in resource-poor settings to reduce the bleeding episodes and improve the quality of life, although the optimal schedule for the same has not been well established. A randomized controlled trial on 33 children with hemophilia A (≤18 years) was done to compare the efficacy of twice versus thrice weekly schedule of prophylactic factor VIII. Group 1 received twice weekly factor VIII prophylaxis while group 2 received thrice weekly factor VIII prophylaxis, the dose in both groups being 10 U/kg. They were evaluated by the bleeding rate and clinical (HJHS 2.1 score and FISH score) and radiological scores (Pettersson score and ultrasound score). All participants were followed up over next 6 months to one year. Data regarding acute bleeding episodes and repeat clinico-radiological assessment at end of follow up were recorded. When analyzed, statistically insignificant difference was found between the bleeding rates after the two prophylaxis regimes. There was a significant improvement between initial and final clinical and radiological scores in both the groups and no difference was recorded in between the groups. To conclude, twice weekly FVIII therapy is effective, easily administered prophylactic schedule to prevent long-term complications of hemophilia A.

The Hemophilia Joint Health Score version 2.1 Validation in Adult Patients Study: A multicenter international study

Background

The Hemophilia Joint Health Score (HJHS) was developed and validated to detect arthropathy in children. Additional evidence is required to show validity in adults. We studied the convergent and discriminant construct validity of the HJHS version 2.1(HJHSv2.1) in adults with hemophilia. A secondary aim was to define age-related normative adult HJHSv2.1 reference values.

Methods

We studied 192 adults with hemophilia, and 120 healthy adults in four age-matched groups-18 to 29, 30 to 40, 41 to 50, and >50 years-at nine centers. Trained physiotherapists scored the HJHS and World Federation of Hemophilia (WFH) joint score. Health history, the Functional Independence Scale of Hemophilia (FISH), Hemophilia Activities List (HAL), and Short-Form McGill Pain Questionnaire (SF-MPQ) were also collected.

Results

The median age was 35.0 years. Of participants with hemophilia, 68% had severe, 14% moderate, and 18% mild disease. The HJHS correlated strongly with WFH score (Spearman's rho [rs ] = .95, P < .001). Moderate correlations were seen between the FISH (rs  = .50, P < .001) and SF-MPQ Present Pain Intensity (rs  = .50, P < .001), while a modest correlation was found with the HAL (rs  = -.37, P < .001). The HJHS significantly differentiated between age groups (Kruskal-Wallis T = 35.02, P < .001) and disease severity in participants with hemophilia. The HJHS had high internal reliability (Cronbach's α = .88). We identified duration of swelling as a redundant item in the HJHS.

Conclusions

The HJHS shows evidence of strong convergent and discriminant construct validity to detect arthropathy in adults with hemophilia and is well suited for use in this population.

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.

Aquatic exercise in patients with haemophilia: Electromyographic and functional results from a prospective cohort study

INTRODUCTION

Recurrent joint bleeds in haemophilia patients often cause musculoskeletal changes leading to functional capacity impairment.

AIM

In this study, we assessed the effects of aquatic activities performed to improve functional capacity in these patients.

METHODS

The interventional protocol consisted of 24 hydrotherapy sessions during three months, in comparison with 24 swimming sessions. The pre- and post-intervention assessment consisted of Functional Independence Score, haemophilia joint health score (HJHS), Pediatric Haemophilia Activities List (PedHAL), surface electromyography (SEMG) of thigh muscles to assess muscle electric activity, and load cell on extensor and flexor thigh muscles to evaluate muscular strength.

RESULTS

Forty-seven haemophilia patients were enrolled in this study, and 32 (23 severe haemophilia A, one moderate haemophilia A and 8 severe haemophilia B), median age 12y (6 to 40y), concluded the aquatic intervention. We observed a statistically significant increase with substantial improvement in functional capacity in the pre- and post-intervention evaluation of hydrotherapy in comparison with the swimming protocol, with HJHS (p = .006 and p = .001 respectively), PedHAL (Sum score) (p = .022 and p = .001) and score FISH (p = .021). The swimming group revealed significant improvements in muscular strength, in all muscles tested (p = .005 and p = .001). SEMG signal amplitude reached significantly higher levels in all muscles evaluated after both interventions except for the vastus medialis (right) in the hydrotherapy group.

CONCLUSION

Our results concluded that both swimming and hydrotherapy were associated with physical improvement in haemophilia patients; however, only hydrotherapy lead to a more significant improvement in functional capacity.

Hemophilia Gene Therapy: Approaching the First Licensed Product

The clinical potential of hemophilia gene therapy has now been pursued for the past 30 years, and there is a realistic expectation that this goal will be achieved within the next couple of years with the licensing of a gene therapy product. While recent late phase clinical trials of hemophilia gene therapy have shown promising results, there remain a number of issues that require further attention with regard to both efficacy and safety of this therapeutic approach. In this review, we present information relating to the current status of the field and focus attention on the unanswered questions for hemophilia gene therapy and the future challenges that need to be overcome to enable the widespread application of this treatment paradigm.

Functional and joint evaluation in a prospective cohort of patients with severe haemophilia

INTRODUCTION

Arthropathy is the main morbidity of haemophilia. Periodic joint health assessment enables a better understanding of the limitations of these patients.

OBJECTIVE

To evaluate the functional and joint performance in patients with haemophilia at one-year follow-up, as well as its association with prophylactic treatment and attendance at scheduled consultations at a haemophilia treatment centre.

METHODS

This prospective cohort study included patients with severe haemophilia aged 7 years or more and treated at Fundação Hemocentro de Brasília, Brazil, from January 2014 to December 2018. The Hemophilia Joint Health Score and Functional Independence Score in Hemophilia were assessed at the first consultation and after a one-year follow-up.

RESULTS

The study included 69 patients. The mean age at study recruitment was 22.5 ± 4.5 years, 62.3% of patients aged 18 years or older, and 29 patients were receiving primary prophylaxis (38.0%). There was a positive correlation between HJHS and age and a negative correlation between FISH and age. The worsening HJHS was associated with non-primary prophylaxis and non-attendance at scheduled multidisciplinary consultations. The worsening FISH was associated with non-primary prophylaxis. The correlation between FISH and treatment adherence was significant for the delta.

CONCLUSION

The older the patient with haemophilia, the higher the probability of a worsening of the HJHS. In the presence of more arthropathies, the older the patient, the worse the FISH. Patients receiving primary prophylaxis show better results in the HJHS and FISH when compared to patients receiving secondary prophylaxis and/or on-demand treatment.

The effects of manual therapy on musculoskeletal system, functional level, joint health and kinesiophobia in young adults with severe haemophilia: A randomized pilot study

INTRODUCTION

The effects of manual therapy (MT) on joint health and functional level in haemophilic arthropathy (HA) have relatively under-explored.

AIM

To investigate the effects of MT in HA of lower limb joints on musculoskeletal system, functional level, Functional Independence Score in Hemophilia (FISH), Hemophilia Joint Health Score (HJHS) and kinesiophobia.

METHODS

Seventeen patients were randomized to the control group (CG = 9) and manual therapy group (MTG = 8). The number of haemarthrosis (NoH) was recorded from the diaries. Range of motion (ROM), strength and pain intensity were measured using goniometer, digital dynamometer and visual analogue scale, respectively. Joint health was evaluated with HJHS, functional independence with FISH, and kinesiophobia with Tampa Scale. Functional Reach (FR), Timed Up-Go (TUG) and 5-Times Sit-to-Stand (5*STS) tests were used to evaluate functional level. Home exercises were given to both groups. Additionally, myofascial release techniques and mobilizations were applied to MTG. Interventions were applied 3 d/weekly for 5 weeks. Assessments were performed at baseline and after treatment.

RESULTS

ROM, strength, activity pain, HJHS and FISH were improved in MTG (p˂0.05). Ankle NoH, 5*STS and FR were developed in both groups (p˂0.05), but kinesiophobia, TUG and knee NoH were not significant. Although improvements were observed in favour of MTG in HJHS, FR, activity pain and ankle strength/ROM (p˂0.05), no significant difference was found in FISH, kinesiophobia, TUG, 5*STS, resting pain and knee strength.

CONCLUSION

Reduction in ankle NoH indicated that both interventions were safe. The use of MT in HA of lower limb joints was an effective physiotherapy approach to improve functional level, joint health and functional independence.

Joint scores in hemophilic arthropathy in children: Developing country perspectives

OBJECTIVE

Hemophilia is a common X-linked recessive coagulopathy causing recurrent bleeding into the synovial joints and results in articular and periarticular abnormalities. To our knowledge, this is the first comprehensive study aimed at studying the clinico-radiological joint score evaluation in hemophilic arthropathy in children from a developing country and its possible impact on the quality of life.

METHODS

In this hospital-based, prospective, descriptive study, all children presenting to the pediatric rheumatology clinic were studied. The joint physical examination was scored using the Hemophilia Joint Health Score 2.1 (HJHS 2.1). The patients were then subjected to imaging of the most affected joint using ultrasonography (USG) and magnetic resonance imaging (MRI). Detailed USG and MRI radiological evaluation was recorded in the predesigned proforma using the Hemophilia Early Arthropathy Detection with Ultra Sound (HEAD-US) score and MRI DENVER score. The physical quality of life as per Functional Independence Score in Hemophilia (FISH) was noted. The clinical, radiological, and functional scores were analyzed with an appropriate statistical measure.

RESULTS

The mean age at presentation was 7.4 years (interquartile range 4.9-10), with the knee being the most common joint involved. All of the USG score, MRI score, and FISH score have a significant correlation (p<0.05), with the HJHS 2.1 score with correlation coefficients of 0.7086, -0.8916, and 0.8607, respectively. USG and MRI had a correlation coefficient of -0.7145 and -0.8326 with FISH, respectively.

CONCLUSION

The degree of association between HJHS 2.1 score was found to be maximum with HEAD-US score, whereas a negative correlation was seen evaluating FISH score with both HEAD-US and MRI DENVER scores. Use of these scores, specifically HEAD-US score, will result in consistent assessment of hemophilic joints, optimizing the management of the destructive changes.

Correlation of Body Mass Index with Pelvis and Lumbar Spine Alignment in Sagittal Plane in Hemophilia Patients

Introduction: Concern about weight gain among people has been high due to negative health consequences in addition to the increasing prevalence of the problem. Overweight and obesity also occur in patients with hemophilia. Analysis of literature shows that increased body weight might have a biomechanical effect on the spatial orientation of the pelvis and the lumbar spine. The aim of this study was to determine the correlation between body mass index (BMI) and the parameters characterizing the alignment of the sacrum (SS, sacral slope), the pelvis (PT, pelvic tilt; PI, pelvic incidence) and the angle value of lumbar lordosis (LL, lumbar lordosis) assessed in the sagittal plane among patients with hemophilia. Materials and methods: A total of 49 patients were subjected to the study, 23 of whom met the inclusion criteria. Body weight and height were measured. Measurement of the angle values of indicators characterizing the position of the lumbar–pelvic complex was established based on X-ray imaging analysis. Results: Analysis of the correlation between the BMI and sacral, pelvic, and lumbar indicators evaluated in the sagittal plane in the study group of patients with hemophilia showed a correlation between BMI and SS (r = 0.48). SS values were significantly and positively related to PI (r = 0.6; p = 0.002) and LL (r = 0.46; p = 0.02). The results obtained indicate the BMI relationship with the setting of the sacrum in the sagittal plane (SS). After adjusting for the knee flexion contracture, the correlation on the border of significance (b = 0.73, p = 0.07) between the body mass index and the spatial orientation of the pelvis and the spine was revealed. Conclusion: We hypothesize that increased body weight among people with hemophilia might have an effect on the positioning of the lumbosacral region. Therefore, it is believed that preventing obesity among people with hemophilia can contribute to a smaller number of intra-articular hemorrhages and better orthopedic condition of the limb joints, and thus could avoid changes in the lumbosacral region as well as their consequences.

Scope of practice of haemophilia physiotherapists: A European survey

INTRODUCTION

European guidelines on the care of haemophilia recommend ready access to a range of services provided by a multidisciplinary team of specialists including physiotherapy. However, the scope of physiotherapy provided is unknown.

METHODS

The Physiotherapists Committee of the European Association for Haemophilia and Allied Disorders (EAHAD) conducted a web-based survey to quantify the role and scope of practice of physiotherapists involved in haemophilia care. The survey was sent to more than 200 physiotherapists registered on the EAHAD database. Questions concerned their work practices including assessment and treatment activities and level of autonomy.

RESULTS

Eighty physiotherapists from twenty-four European countries responded. Considerable heterogeneity exists in roles, responsibilities, and clinical practice of physiotherapists, particularly in access to and type of physiotherapy treatment provided, as well as the skill set and autonomy of physiotherapists to make independent assessment and treatment decisions.

DISCUSSION

This pan-European survey establishes a context to support physiotherapy role development and professional identity. Key recommendations include the following: (a) establishing a pan-European network to support collaboration and education for physiotherapists working in haemophilia, (b) developing a core skills and capability framework to ensure person-centred approaches are central as well as working in partnership with those with the condition to maximize early recovery, support self-management and enablement in remaining active and independent, (c) regular training, standardized validation and maintenance of competency for assessment tools, (d) well-designed randomized clinical studies with larger numbers of participants from multiple sites should be the focus of future research.

Investigating the relationship between the HJHS and HAL in routine clinical practice: A retrospective review

INTRODUCTION

Comprehensive musculoskeletal assessment for monitoring joint health in haemophilia includes both physical assessment with Haemophilia Joint Health Score (HJHS) and assessment of self-reported function by Haemophilia Activities List (HAL).

METHODS

Correlation between physical assessment and joint function was undertaken between HJHS and HAL in patients with SHA and SHB who had both assessments at the same visit over a one-year period.

RESULTS

Data from 120 patients (96-SHA/24 = SHB) with a median age 33 years (range 19-73) were included. Median total HJHS was 19, increasing with age: 18-30 years-7, 31-50 years-25 and 51-73 years-44. Similarly, median total HAL score was 80 with decreased function associated with increasing age: 18-30 years-90.4, 31-59 years-71.7, 51-73 years-49.5. Median Total HJHS and HAL demonstrated strong correlation (r_s  = 0.66, P < 0.01). Moderate-to-strong correlations were seen across the entire age group between the HJHS LL and UL subtotals and corresponding limb HAL domains. Within age groups, correlations were less significant particularly for the upper UL domains in HAL and the UL HJHS score. The wide range of ROM in joints categorized as markedly affected (ie, ROM loss score = 3) highlights the potential ceiling effect of this domain score and its use in chronically damaged joints.

CONCLUSION

HJHS and HAL showed moderate-to-strong correlation with discrepancy in some individual patients. Prospective studies are required to better understand the clinical utility of both especially in severe joint disease where HAL may have a potential advantage.

Evaluation of early musculoskeletal disease in patients with haemophilia: results from an expert consensus

: Early joint damage in patients with haemarthrosis often escapes diagnosis because of insufficient investigation of biomechanical changes. Arthropathy in haemophilia requires complex assessment with several tools. Considering the increased emphasis on an integrated approach to musculoskeletal (MSK) outcomes, re-evaluation of MSK assessment to address individual patient needs is warranted. To advise on the optimal use of current assessment tools and strategies for tailored MSK evaluation in patients with haemophilia. A panel of experts in haemophilic arthropathy evaluated internationally recognized assessment tools through published literature and personal expertise. Each tool was considered, scored and ranked for their utility in the clinical assessment of MSK damage. Subsequently, a patient evaluation table detailing advice on type and frequency of assessments for different patient populations was constructed. To obtain a complete MSK assessment, multiple tools must be used to ensure each criterion is evaluated. For patients with haemophilia, clinical examination of the joint, disease-specific structure/function scores, and activity/participation scores including quality of life are important, and should be performed on a regular basis according to age and clinical condition. Joint imaging is recommended in the prevention, diagnosis and follow-up of haemophilic arthropathy and should be used in conjunction with joint structure and function scores. An integrated approach to MSK assessment using combinations of tools will allow earlier management of dysfunction and may improve long-term outcomes. This approach could be used in long-term follow-up of all patients independent of age and disease stage, especially in children to prevent arthropathy.

A Combined Ultrasonographic and Conventional Radiographic Assessment of Hemophilic Arthropathy

Hemophilic arthropathy (HA) can be diagnosed by a number of imaging studies. However, it is difficult with conventional radiography to find soft tissue structures around joints, and ultrasonography has limited effectiveness in evaluating internal bony structures. We attempt to determine whether a combination of ultrasonography for soft tissue around joints and conventional radiography for bony structures can be used as a cost-effective imaging tool for evaluating HA and whether it reflects the functional status of hemophilic patients. Thirty-six males (median age 16.5 years; severe 34, mild 2) with hemophilia were recruited. We evaluated the severity of HA using combined imaging score that consisted of modified Petterson X-ray score (mPXS) and the modified ultrasonographic score (mUS). Joint impairment was clinically assesses using the World Federation of Hemophilia-Physical Examination (WFH-PE) scale and the Hemophilic joint health score (HJHS). We assessed the Hemophilia activities list (HAL) for the functional level. We performed a comparative analysis between the combined imaging score and the joint impairment scores as well as the functional scores. The mean mUS was 4.97 ± 3.99 points, and the mean mPXS was 2.85 ± 2.91 points; the combined imaging score was 7.83 ± 6.31 points. The combined imaging score was significantly correlated with the HJHS (p = 0.006) and WFH-PE scores (p = 0.019) as well as the HAL score (p = 0.002). A combination of conventional radiological and ultrasongraphic study might ultimately impact the optimal evaluation of joint impairment and functional status in hemophilic patients.

Imaging of haemophilic arthropathy in growing joints: pitfalls in ultrasound and MRI

The purpose of this review was to summarize the current knowledge on the utilization of magnetic resonance imaging (MRI) and ultrasound (US) for assessing arthropathy in children and adolescents with haemophilia and to recognize the limitations of each imaging modality and pitfalls in the diagnosis of soft tissue and osteochondral abnormalities. Awareness of MRI and US limitations and pitfalls in the assessment of joints in persons with haemophilia is essential for accurate diagnosis and optimal management of haemophilic arthropathy.

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.

Pilot study of once-a-day prophylaxis for youth and young adults with severe haemophilia A

INTRODUCTION

Standard prophylaxis has been shown to be an effective treatment for severe haemophilia A. According to pharmacokinetic principles, daily factor infusions of smaller doses can maintain similar trough factor VIII (FVIII) levels, and perhaps the same protection as standard prophylaxis.

AIM

This multicentre study examined the feasibility of daily prophylaxis for youth and young adults with severe haemophilia A in Montreal and Toronto.

METHODS

Bleeding rates, joint status, quality of life and physical activity were monitored for 14 patients during this study. At baseline, subjects continued their regular treatment regimen and switched to daily prophylaxis after 4 months; nine had begun daily prophylaxis before enrolment. Additional visits occurred at 8 and 12 months which included a physical examination, inhibitor testing, HJHS and FISH assessments, the CHO-KLAT/Haemo-QoL-A and PDPAR. Treatment satisfaction was assessed using the Treatment Satisfaction Questionnaire for Medication ver.II and perceived difficulty questions at the end of study.

RESULTS AND CONCLUSIONS

There were no significant changes in quality of life except for concerns with the demanding daily infusion schedule. The number of bleeds did not statistically differ from the initial 4 months of the study to the last 8 months. Monthly bleeding rates from the year prior to the study and during the intervention phase were not statistically different. It was also found that daily prophylaxis used 24% less FVIII compared to standard prophylaxis. Taking all of this into account, we have found that providing daily prophylaxis is feasible and that it is feasible to prospectively study daily prophylaxis in youth and young adults.

Assessment of Musculoskeletal Function and its Correlation with Radiological Joint Score in Children with Hemophilia A

OBJECTIVE

To evaluate the functional independence of children with hemophilia A and its correlation to radiological joint score.

METHODS

The present cross sectional study was conducted at SPMCHI, SMS Medical College, Jaipur, India. Children in the age group of 4-18 y affected with severe, moderate and mild hemophilia A and with a history of hemarthrosis who attended the OPD, emergency or got admitted in wards of SPMCHI, SMS Medical College were examined. Musculoskeletal function was measured in 98 patients using Functional Independence Score in Hemophilia (FISH) and index joints (joints most commonly affected with repeated bleeding) were assessed radiologically with plain X rays using Pettersson score.

RESULTS

The mean FISH score was 28.07 ± 3.90 (range 17-32) with squatting, running and step climbing as most affected tasks. The mean Pettersson score was 3.8 ± 3.2. A significant correlation was found between mean Pettersson score and FISH (r = -0.875, P < 0.001) with knee and elbow having r = -0.810 and -0.861 respectively, but not in case of ankle with r = -0.420 (P 0.174).

CONCLUSIONS

The FISH and radiological joint (Pettersson's) scores may be extremely useful in the clinical practice in the absence of magnetic resonance imaging (MRI), which is considered very sensitive to detect early joint damage, but at a cost that makes it relatively inaccessible. FISH seems to be a reliable tool for assessment of functional independence in patients with hemophilia A.

Comparing the Quality of Life of Patients With Hemophilia and Juvenile Idiopathic Arthritis in Which Chronic Arthropathy Is a Common Complication

INTRODUCTION

Hemophilia is a genetic disorder in which recurrent joint bleeding causes arthropathy. Inflammation and degeneration play roles in the pathogenesis of hemophilic arthropathy. Patients with juvenile idiopathic arthritis (JIA) experience a similar inflammatory degenerative joint disease. A comparison of different patients with common pathogenetic features may identify unique features helpful in terms of the follow-up.

AIM

We compared the quality of life (QoL) of patients with hemophilia and JIA, and healthy controls, using a generic QoL scale, Kidscreen and Disabkids Questionnaires (KINDL). Differences among groups were evaluated in terms of sociodemographic characteristics and clinical parameters affecting the QoL.

METHODS

We included 33 hemophilia patients, 19 JIA patients, and 32 healthy individuals aged 4 to 18 years. Sociodemographic characteristics (the age, the maternal educational status, the place of residence, the size of the household, the household income, divorced parents) were noted, and the KINDL was administered to all participants. Clinical parameters associated with arthropathy (the functional independence score [FISH], the hemophilia joint health score [HJHS], the arthropathic joint count, and the painful joint count) were documented. Differences in frequencies and medians among the groups were evaluated using the χ, the Mann-Whitney U, and the Kruskal-Wallis tests.

RESULTS

All KINDL dimensions were above 50, reflecting "good conditions" in the 2 patient groups. No difference between patients with hemophilia and JIA was evident in terms of the clinical parameters of FISH, the HJHS, or the arthropathic or painful joint counts (P>0.05). Sociodemographically, only the frequency of literate mothers was lower in patients with hemophilia than in those with JIA and healthy controls (P=0.03). Patients with JIA scored more higher on the KINDL dimension of chronic illness than those with hemophilia (P=0.02). The FISH score correlated with the total QoL score in both patients with hemophilia and JIA (r=0.39, P=0.03 and r=0.48, P=0.04, respectively).

CONCLUSIONS

Although no difference was evident between the patient groups in terms of clinical parameters associated with arthropathy, JIA patients coped better with illness than those with hemophilia. JIA patients had a higher proportion of literate mothers than hemophilia patients; this may affect a patient's ability to cope with issues relating to chronic illness. Implementation of an educational program for mothers of hemophilia patients, during follow-up, may improve the patient's QoL. Also, hemophilia patients should be assisted to improve their QoL in the dimensions of self-esteem and schooling. Lastly, the evaluation of functional disability by FISH in hemophilia patients is important because the FISH score correlated with the total QoL score, as revealed by KINDL. In JIA patients also, functional disabilities caused by arthropathy affected the QoL.

A comparison between MRI, sonography and Functional Independence Score in Haemophilia methods in diagnosis, evaluation and classification of arthropathy in severe haemophilia A and B

Evaluation of joints in children with haemophilia is important in detecting abnormalities, staging their severity and following the effects of treatment. The aim of this study is to evaluate the correlation of FISH score (Functional Independence Score in Haemophilia) with the scores obtained by MRI and sonography for the diagnosis, evaluation and classification of arthropathy in severe haemophilia. In this cross-sectional study on 25 severe haemophilia patients, FISH, MRI and sonography procedures were performed in the elbow or knee joint. All patients' information, including age, type of haemophilia, affected joint, scores of MRI, sonography and FISH, dose of factor consumed, weight and prophylaxis protocol were collected and analysed. Among the 25 patients (age range of 11-70 years), 22 patients were haemophilia A and three patients were haemophilia B. Affected joints were right knee in 12 patients, left knee in nine and right elbow in four. There was only a statistically significant negative correlation between FISH and MRI Additive (A) scale (rs = -0.537, P = 0.006). Considering cartilage loss domain (related MRI A scale: 13-20), 20 patients (80%) were classified in this group with FISH scores ranged from 17 to 22. On the basis of our results, FISH scores in severe haemophilia patients were negatively correlated with MRI A scale. Also, it seems that a FISH score less than 22 could be considered as loss of cartilage; however, due to the small number of our patients, it needs further assessment in different populations.

Outcome measures in haemophilia: a systematic review

Haemophilia A and B are hereditary X-linked disorders due to deficiency (or absence) of coagulation factor VIII or IX, respectively. Bleeding risk is related to the severity of factor deficiency. Repeated joint bleeding can lead to a severe haemophilic arthropathy resulting in disabilities. Outcome measurements in persons with haemophilia (PWH) have been limited to laboratory evaluation (factor VIII or IX levels) and clinical outcomes (such as bleeding frequency), morbidity (for example linked with arthropathy) and mortality. Due to the new standard of care of PWH, there is a need to consider other outcome measures, such as the early detection and quantification of joint disease, health-related quality of life (QoL) and economic or cost-utility analyses. To investigate this, we performed a 10-yr systematic overview of outcome measures in haemophilia. Only clinical trials including at least 20 patients with haemophilia A or B were included. To facilitate the search strategy, eight issues of outcome measures were selected: physical scores, imaging technique scores, functional scores, QoL measurement, mortality, bleeding frequency, cost and outcome and bone mineral density. The results of these will be discussed. Clearly defined outcomes in haemophilia care are important for many reasons, to evaluate new treatments, to justify treatment strategies, to allow a good follow-up, to perform studies and to allocate resources. The use of such scoring systems is clearly recommended by experts in haemophilia care. However, most centres do not perform such scores outside clinical trials due to reasons such as lack of time and resources.

The effectiveness of tools for monitoring hemophilic arthropathy

INTRODUCTION

Hemophilic arthropathy is the most important cause of morbidity in patients with hemophilia. The earliest alterations that occur during the development of hemophilic arthropathy can be shown using magnetic resonance imaging (MRI). In addition, various tools have been developed to monitor joint health.

AIM

: The purpose of this study was to determine the correlation between these tools when used to assess hemophilia patients.

METHODS

This cross-sectional study enrolled 38 hemophilia patients between 2 and 18 years of age. Hemophilia Joint Health Score (HJHS) and radiologic scores (Pettersson and Arnold-Hilgartner) were used to evaluate the joints of the patients (n=236). Magnetic resonance imaging (MRI) was performed on 46 joints that were pathologic according to the HJHS. These joints were imaged bilaterally; therefore, 14 normal joints were imaged. In addition, the Functional Independence Score in Hemophilia (FISH) was used to evaluate the joints of 33 patients.

RESULTS

The HJHS scores were correlated with the MRI and FISH scores. The annual bleeding rate was not correlated with any scores; however, the number of painful joints was correlated with the MRI scores. The radiologic scores were correlated weakly with progressive score and HJHS.

CONCLUSION

The agreement between the HJHS scores and the MRI scores suggests that the HJHS may be used safely as a first-line tool. We recommend that the FISH should be used in the routine follow-up of hemophilia patients as a functional evaluation tool. Painful joints may be useful in deciding to apply MRI, whereas the bleeding frequency may not be useful.
