Pain management in patients with haemophilia: a European survey

Clinical and Humanistic Burden of Non-inhibitor Haemophilia A in Five European Countries: Insights from the CHESS II Study

INTRODUCTION

Haemophilia A (HA) is a congenital bleeding disorder caused by a deficiency/absence of factor VIII (FVIII) and characterised by frequent, acute and prolonged spontaneous or traumatic bleeding events, often leading to haemophilic arthropathy and progressive joint deterioration. HA severity is characterized by endogenous FVIII activity: mild (> 5-40%), moderate (1-5%), or severe (< 1%). HA poses a substantial clinical and socioeconomic burden on people with HA (PWHA), their caregivers, and society. This analysis evaluates clinical and patient-centric outcomes of a cohort of individuals with non-inhibitor HA sampled from France, Germany, Italy, Spain, and the UK in the 'Cost of Haemophilia in Europe: A Socioeconomic Survey II' (CHESS II) study.

METHODS

CHESS II was a cross-sectional burden-of-illness study collecting clinical and socioeconomic data on adult (≥ 18 years) individuals with haemophilia A or B of any severity with or without inhibitors from eight European countries. Descriptive analyses were conducted examining physician-reported demographics, clinical and health resource utilisation information. PWHA-reported health-related quality of life (HRQoL) using the EQ-5D-5L and Work Productivity and Activity Impairment (WPAI) were also examined. Outcomes were stratified by HA severity and reported at country level.

RESULTS

Demographics and clinical characteristics of the cohort (N = 880) were generally consistent across countries. Individuals with severe HA experienced more frequent bleeding events and joint disease despite broad use of factor replacement therapy long-term prophylaxis. A minority of those with mild or moderate HA also experienced such challenges. HRQoL and workforce participation diminished, and chronic pain increased, with increasing HA severity.

CONCLUSION

This analysis provides up-to-date insights on the impact of HA across five European countries. Increasing HA severity was generally associated with worse clinical outcomes, HRQoL and workforce participation. These findings suggest a place for continued evidence-based tailored treatment and clinical management approaches in addressing the residual burden of HA.

Exploring the relationship between condition severity and health-related quality of life in people with haemophilia A across Europe: a multivariable analysis of data from the CHESS II study

BACKGROUND

Haemophilia A (HA; Factor VIII deficiency) is a congenital X-linked bleeding disorder characterized by trauma-related or spontaneous bleeding events, most notably arising within the intraarticular space and resulting in chronic inflammation and degeneration of affected joints. Endogenous clotting factor activity relative to normal levels determines the severity of HA symptoms, as mild (> 5-40%), moderate (1-5%), or severe (< 1%). Within the current environment of rapid evolution in HA management, we seek to understand the interplay of condition severity and health-related quality of life (HRQoL) to characterise and differentiate unmet needs among people with HA (PwHA).

METHODS

A generalised linear regression model (GLM) was developed to explore the relationship between HA severity and EQ-5D-5 L index score from adult HA patients sampled in the "Cost of Haemophilia across Europe - a Socioeconomic Survey II" (CHESS II) cross-sectional, retrospective burden of illness study among adults with hereditary haemophilia A or B from eight European countries. HA patients of any severity with no active inhibitors during the 12 months prior to data capture and a completeEQ-5D-5 L response were included. A base GLM model was specified with covariates for demographic and clinical characteristics (age, body mass index, country, employment, HA severity, annual bleeding rate, problem joints, and chronic pain).

RESULTS

Of 381 evaluable patients, 221 (58.0%) had severe HA, 96 (25.2%) had moderate HA, and 64 (16.8%) had mild HA. Among the covariates included in the GLM model and after controlling for haemophilia-related outcomes, a significant association was observed between mild HA and higher EQ-5D-5 L index score (average marginal effects, 0.084; p = 0.016) relative to severe HA. Patient country of residence and magnitude of HA-related chronic pain were also associated with significant differences in index scores, with the latter showing a negative relationship with HRQoL outcomes.

CONCLUSIONS

Condition severity and chronic pain are significant predictors of HRQoL in PwHA. Durable bleeding protection and effective management of chronic pain have the potential to address unmet treatment needs in this population.

Patient Perspective on Disease Burden and Gene Therapy for Hemophilia A and B: The "Haemvolution for Patients" Italian Survey

Hemophilia is a rare X-linked congenital bleeding disorder due to a deficiency of factor VIII (hemophilia A [HA]) or factor IX (hemophilia B [HB]). Replacement and nonreplacement treatments are available but have limitations. Gene therapy (GT) provides an effective, long-term, single-dose treatment option, now approaching clinical practice. This study aimed to understand patient perspectives on GT for HA and HB in Italy using a qualitative questionnaire distributed through Italian patient associations, addressing patient views on daily life, treatments, unmet needs, quality of life (QoL), and GT for hemophilia. In total, 141 participants had HA, and 14 had HB (severe 78.6%). Daily life was most affected by pain and/or joint function limitations (57.5% of participants), high infusion frequency (42.5%), management of breakthrough bleeding episodes (40.3%), and anxiety/fear of severe or sudden bleeding (38.8%). Despite current treatments, about half of the participants experienced three or more annual bleeding episodes. Most participants knew of GT (87.2%) and expected improvements in QoL (60.5%), reduced frequency of current treatments (53.5%), and a permanent cure (49.1%); 46.4% were unaware of its once-off dosage and 46.4% were not concerned about the costs they anticipated to be associated with GT. Although several fears were reported, 25.0% of participants were willing to undergo GT with the support of a multidisciplinary team. This survey provided valuable insight into patient perspectives on hemophilia and GT in Italy. Overall, relevant proportions of patients still experience limitations affecting their daily life. Most were positive about GT and anticipated improvements in their clinical outcomes and QoL.

Structural alterations and pain perception at the ankle joint in patients with haemophilia

BACKGROUND

Patients with haemophilia (PwH) suffer from chronic pain due to joint alterations induced by recurring haemorrhage.

OBJECTIVES

This study aimed to investigate the relationship between structural alterations and pain perception at the ankle joint in PwH.

PATIENTS/METHODS

Ankle joints of 79 PwH and 57 healthy controls (Con) underwent ultrasound examination (US) and assessment of pain sensitivity via pressure pain thresholds (PPT). US discriminated between joint activity (synovitis) and joint damage (cartilage and/or bone degeneration) applying the HEAD-US protocol. Based on US-findings, five subgroups were built: PwH with activity/damage, PwH with activity/no damage, PwH with no activity/no damage, controls with activity/no damage and controls with no activity/no damage.

RESULTS

Joint activity and joint damage were significantly increased in ankles of PwH compared to Con (p ≤.001). Subgroup analysis revealed that structural alterations negatively impact pain perception. This is particularly evident when comparing PwH with both activity/damage to PwH with no activity/no damage at the tibiotalar joint (p = .001). At the fibulotalar joint, no significant differences were observed between PwH subgroups. Further analysis showed that both joint activity and joint damage result in an increase in pain sensitivity (p ≤.001).

CONCLUSION

The data suggest a relation between joint activity, joint damage and pain perception in PwH. Even minor changes due to synovitis appear to affect pain perception, with the effect not intensifying at higher levels of inflammation. In terms of joint damage, severe degeneration leads to a sensitised pain state most robustly, whereas initial changes do not seem to significantly affect pain perception.

Foam roller-based self-induced myofascial therapy in patients with hemophilic knee arthropathy: a multicenter, single-blind, randomized clinical study

BACKGROUND

Hemophilia is a congenital coagulopathy characterized by degenerative joint damage. Self-induced myofascial therapy aims to decrease pain and improve tissue mobility, functionality and proprioception.

AIM

The aim of this study was to evaluate the safety and efficacy of self-induced myofascial release in patients with hemophilic knee arthropathy.

DESIGN

This is a randomized clinical study.

SETTING

This study was carried out in different patient associations.

POPULATION

Fifty-two patients with hemophilia were included in the study.

METHODS

Patients were randomized to the experimental group (daily home protocol of foam roller-based self-induced myofascial therapy for 8 weeks) or the control group (no intervention). The variables were the frequency of hemarthrosis (self-reporting), pain intensity (visual analog scale), range of motion (goniometry) and muscle strength (dynamometry). All variables were evaluated at baseline, post-treatment and after a 10-week follow-up.

RESULTS

The patients included in the experimental group showed significant improvements in terms of a decrease in frequency of hemarthrosis (mean difference [MD]=-0.61; 95% confidence interval [CI]: -0.81; -0.41) and pain intensity (MD=-0.33; 95% CI: -0.48, -0.18), increased range of motion (MD=0.88; 95% CI: 0.39; 1.37), strength in quadriceps (MD=0.88; 95% CI: 0.39; 1.37). (MD=12.39; 95% CI: 3.44; 21.34) and hamstrings (MD=7.85; 95% CI: 0.60; 15.11). There were intergroup differences in the frequency of hemarthrosis (F=14.51; P<0.001), pain intensity (F=9.14; P<0.001) and range of motion (F=13.58; P<0.001).

CONCLUSIONS

Self-induced myofascial therapy can be an effective complementary technique in the treatment of patients with hemophilic arthropathy. Self-induced myofascial therapy can reduce the frequency of knee hemarthrosis in patients with hemophilia. This technique can improve pain intensity and range of motion in patients with hemophilic knee arthropathy.

CLINICAL REHABILITATION IMPACT

Hemophilic knee arthropathy is characterized by chronic pain, decreased range of motion, and periarticular muscle atrophy. Foam roller-based self-induced myofascial therapy can reduce the frequency of hemarthrosis and pain intensity and improve range of motion in patients with hemophilic arthropathy. Foam roller-based self-induced myofascial therapy is safe and effective in the treatment of patients with hemophilia. The inclusion of self-induced myofascial therapy exercises in the approach to degenerative joint pathologies may be an effective and safe treatment option.

Pain: a neglected symptom in hemophilia

Repetitive bleeding attacks may cause joint pain and arthropathy in patients with hemophilia (PWH). Despite being a common symptom, pain is not a well-studied topic in this disease. The aim of this cross-sectional, observational study was to assess the frequency and intensity of pain and analyze the success rates ofpain treatment methods. Adult hemophilia patients were included in the study. The Multidimensional Hemophilia Pain Questionnaire (MHPQ) was used to assess pain. In addition to the MHPQ, demographic data were collected. Fifty adult hemophilia patients were included in the study. Thirty-one (62%) of the patients reported pain due to hemophilia in the last year. Twenty-six of them (81.2%) reported pain during bleeding attacks. The most successful pain coping strategy was clotting factor replacement. None of the participants used opioids or adjuvant analgesics. None of them used a physical therapy modality or interventional pain therapy method. While 67.6% of the patients were very dissatisfied or dissatisfied with their global pain treatment, only 16.1% of the patients were satisfied or very satisfied. Patients with higher pain during bleeding episodes were more likely to continue their prophylaxis. There was no significant difference between plasma-derived or recombinant-derived factor prophylaxis in terms of pain complaints. Pain is a frequent and important symptom of hemophilia, but most of the patients are not treated sufficiently. A multidisciplinary approach is needed to improve the life quality of the patients. In addition to successful bleeding prophylaxis, administration of a proper and adequate analgesic regimen and combined physical therapy modalities may decrease pain intensity and prevent the development of arthropathy.

Self-Induced Myofascial Release in Patients with Hemophilic Ankle Arthropathy: A Pilot Observational Study

Background: Hemophilic ankle arthropathy is manifested by degenerative functional alterations (reduced muscle strength, mobility, and proprioception) and chronic pain. Myofascial release techniques are used to treat soft tissue adhesions, relieve pain, and reduce tissue sensitivity. The aim was to evaluate the safety of self-induced myofascial release in patients with hemophilic ankle arthropathy and to assess possible changes in musculoskeletal variables. Methods: We recruited 20 patients with ankle hemophilic arthropathy. Patients carried out a daily self-induced myofascial release exercise program using a foam roller over a period of 8 weeks. The primary variable was the frequency of hemarthrosis (regular telephone follow-up). Secondary variables were pain intensity (visual analog scale), range of motion (goniometry), and functional capacity of the lower limbs (six-minute walk test). Three evaluations were performed: pre-treatment (T0), post-treatment (T1), and at 8 weeks follow-up (T2). Results: There was a lower, non-significant, association in the frequency of hemarthrosis between the experimental and follow-up periods, compared to the pre-study period (SE = 0.50; 95%CI: −1.67; 0.28). There were significant within-subject changes in intensity of pain (T0: 4.91; T1: 2.79; T2: 2.46; p < 0.001), plantar flexion (T0: 125.55; T1: 131.5; T2: 130.30; p = 0.01), and functionality of the lower limbs (T0: 173.06; T1: 184.85; T2: 178.39; p = 0.009). Conclusions: Self-induced myofascial release is safe in patients with hemophilic ankle arthropathy. A protocol based on self-induced myofascial release can lead to changes in pain intensity, range of ankle motion in plantar flexion, and functionality in hemophilic patients.

Gene therapy for hemophilia: looking beyond factor expression

Hemophilia A (factor VIII [FVIII] deficiency) and hemophilia B (factor IX [FIX] deficiency) are the X-linked recessive bleeding disorders that clinically manifest with recurrent bleeding, predominantly into muscles and joints. In its severe presentation, when factor activity is less than 1% of normal, hemophilia presents with spontaneous musculoskeletal bleeds and may progress to debilitating chronic arthropathy. Management of hemophilia has changed profoundly in the past decades. From on-demand to prophylactic factor concentrate replacement, the treatment goal shifted from controlling bleeds to preventing bleeds and improving quality of life. In this new scenario, gene therapy has arisen as a paradigm-changing therapeutic option, a one-time treatment with the potential to achieve sustained coagulation FVIII or FIX expression even within the normal range. This review discusses the critical impact of adeno-associated virus (AAV) gene transfer in hemophilia care, including the recent clinical outcomes, changes in disease perceptions, and its treatment burden. We also discuss the challenging scenario of the AAV-directed immune response in the clinical setting and potential strategies to improve the long-lasting efficacy of hemophilia gene therapy efficacy.

Prevalence of pain in adult patients with moderate to severe haemophilia: a systematic review

OBJECTIVES

Patients with haemophilia (PwH) often suffer from joint pain due to repetitive haemarthroses and resulting arthropathy. Literature focuses so far on pain causes, diagnosis or treatment. A summary of prevalence rates, providing facts on the absolute occurrence of pain, is not sufficiently described so far. This review aimed to explore and systematically review different pain conditions, focussing on prevalence rates of pain in adult PwH.

METHODS

A review of English articles using PubMed and Web of Science was conducted in February 2020. The search strategy included patients with haemophilia A or B suffering from pain. The articles were selected based on defined PICOS-selection criteria.

RESULTS

Out of 606 identified articles, 13 studies matched the given eligibility criteria and indicated pain prevalence rates. The weighted mean (WM) for the prevalence rate (varying timeframes) for chronic pain was 40% whereas for point prevalence the rate was WM=75%. Regarding pain intensity, findings of the EQ-5D-3L revealed moderate pain to be more present (61.0%) compared to extreme (11.6%). The main problem was the inconsistency of the definition of both acute and chronic pain as well as for prevalence types.

CONCLUSIONS

Pain is a major problem in patients with haemophilia. Pain therapy should be carried out taking into account the difference between bleeding-related or arthropathy-related causes of pain. In addition, the intensity and duration of pain should be recorded consistently to better monitor therapy and allow comparison with existing data.

Pain in Hemophilia: Unexplored Role of Oxidative Stress

Hemophilia is the most common X-linked bleeding diathesis caused by the genetic deficiency of coagulation factors VIII or IX. Despite treatment advances and improvements in clinical management to prevent bleeding, management of acute and chronic pain remains to be established. Repeated bleeding of the joints leads to arthropathy, causing pain in hemophilia. However, mechanisms underlying the pathogenesis of pain in hemophilia remain underexamined. Herein, we describe the novel perspectives on the role for oxidative stress in the periphery and the central nervous system that may contribute to pain in hemophilia. Specifically, we cross examine preclinical and clinical studies that address the contribution of oxidative stress in hemophilia and related diseases that affect synovial tissue to induce acute and potentially chronic pain. This understanding would help provide potential treatable targets using antioxidants to ameliorate pain in hemophilia.

Improvement in pain-related quality of life in patients with hemophilia A treated with rFVIIIFc individualized prophylaxis: post hoc analysis from the A-LONG study

Background:

Pain, a common symptom of hemophilia, begins early in life primarily due to joint bleeding. Recurrent bleeding adversely affects patients’ pain-related physical functioning, which can negatively impact their quality of life (QoL).

Objective:

Post hoc analysis of data from the A-LONG study (NCT01181128), to assess change over time in pain-related QoL in patients with severe hemophilia A treated prophylactically with recombinant factor VIII Fc fusion protein (rFVIIIFc).

Methods:

Patients who completed Haem-A-QoL (17–65 years) and EQ-5D-3L (⩾12–65 years) questionnaires at baseline (BL) and end of study (EoS). Individual-level changes were assessed using three pain-related items of the Haem-A-QoL ‘Physical Health’ domain and the pain/discomfort item of EQ-5D-3L. Distributions of responses (EoS versus BL) were compared using McNemar’s test.

Results:

A significantly greater proportion of patients reported they did not experience painful swellings ( n = 87; 66% versus 46%, p <  0.01) or pain in their joints ( n = 89; 42% versus 27%; p <  0.05) at EoS versus BL. The proportion of patients who did not find it painful to move numerically increased at EoS versus BL ( n = 86; 47% versus 38%; p = NS). A significantly greater proportion of patients reported no pain/discomfort at EoS versus BL ( n = 116; 45% versus 34%; p <  0.05).

Conclusion:

This study reports the effect of FVIII prophylaxis on patient-reported measures of pain over time in patients with severe hemophilia A. The results of this post hoc analysis showed improvements in pain from BL to EoS in patients receiving rFVIIIFc individualized prophylaxis indicating effective pain management, a key component of patient care.

Effectiveness of hypnosis for pain and health-related quality-of-life among people with hemophilia: Three-month outcomes of a randomized controlled pilot trial

BACKGROUND AND PURPOSE

Pain is a common condition among people with hemophilia (PWH), negatively impacting quality of life. However, effective treatment remains a challenge. This two-arm, parallel randomized controlled pilot trial aimed to examine the three-month effects of hypnosis intervention on clinical and psychosocial variables, and on the inflammatory profile of PWH.

MATERIALS AND METHODS

The study was conducted between January and October 2018, in a Reference Center for Congenital Coagulopathies. Adult (age ≥18) patients were randomized to experimental group (EG) or control group (CG). The EG received four weekly hypnosis sessions plus treatment-as-usual, and the CG maintained treatment-as-usual only. Outcomes were evaluated at one week and three months post-intervention and included pain, joint status, health-related quality of life (HRQoL), emotional state and inflammatory profile (leukocytes, C-reactive protein, cytokines). The randomization sequence was computer-generated, and allocation was concealed until enrolment. The outcome assessor was blind to allocation, but blinding of the participants was not possible due to the differences in procedure.

RESULTS

Twenty patients were randomized to EG (n = 10; 8 analyzed) or CG (n = 10; 10 analyzed). Two-way mixed ANOVA showed significant time × group interactions on pain interference with normal work and with relations with other people, and on perception of health status. The EG significantly improved in pain interference with normal work and perception of health status. There was no report of harm.

CONCLUSION

Hypnosis may be a promising intervention to manage hemophilia-related pain and promote HRQoL, with benefits lasting up to three months.

Prevalence and Interference of Chronic Pain Among People With Hemophilia: A Systematic Review and Meta-Analysis

Chronic pain is a common condition among people with hemophilia (PWH), associated with joint deterioration due to repeated joint bleeds. This systematic review and meta-analysis aimed to determine the prevalence of chronic pain due to haemophilia and to analyze its interference in the lives of patients. A systematic search was performed in May and June 2019 and updated in February 2021, using PubMed, EMBASE, Web of Science and SciElo. The search included terms related to hemophilia, pain, pain prevalence and pain interference. Studies were included if they reported data referring to hemophilia-related chronic pain among adult males (age ≥18). From 3,258 identified studies, 11 met the inclusion criteria. Three studies used a proposed definition for hemophilia-related chronic pain and 8 used direct questions developed by the authors. For the global samples, prevalence ranged from 17% to 84%. The random-effects meta-analysis including all studies demonstrated a pooled prevalence of chronic pain of 46% (95% Confidence Interval, CI = 34%-58%). Subgroup analysis of samples including all disease severities or including only severe patients revealed a pooled prevalence of 48% (95% CI = 29%-67%) and 53% (95% CI = 38%-69%), respectively. High heterogeneity between studies was observed in all models. Information concerning chronic pain interference was retrieved from 1 study, reporting a mean interference of 3.7 (0-10 numerical rating scale from the Brief Pain Inventory). This systematic review revealed a wide prevalence range of hemophilia-related chronic pain across studies, varying methodologies and sample characteristics. Research in the hemophilia field should clearly distinguish between acute and chronic pain and provide complete characterization of study samples. PERSPECTIVE: Pain is a central issue in the lives of people with hemophilia, posing a significant challenge for healthcare providers. A clear picture of chronic pain due to hemophilia is precluded by high heterogeneity among studies and various definitions used to investigate its prevalence.

Pain management in hemophilia: expert recommendations

INTRODUCTION

As a typical consequence of bleeding into muscles and joints, patients with severe hemophilia suffer from acute and chronic pain. In spite of its high prevalence, pain in this patient group is not always sufficiently considered or treated in an effective manner.

AIM

The recommendations presented in this paper address possible improvements in pain management in hemophilia patients and particularities that have to be taken into account in this patient group.

METHOD

The manifold aspects of pain management in hemophilia patients were discussed within the framework of an expert meeting. Based on the available literature and the experts' clinical experience, the participants developed a set of recommendations presented in this paper.

RESULTS

Pain management in patients with hemophilia is often insufficient, a fact that not only influences the patients' quality of life but also implies the risk of difficult to manage chronic pain. Both the prevalent polypharmacy (due to comorbidities) as well as the underlying disease itself present special challenges to pain therapy in this patient group. The present review and recommendations are intended to support medical professionals in recognising the risks of pain chronicity, applying basic principles of multimodal pain therapy, including the options of psychological intervention and modalities of physical medicine in therapy concepts, and reaching a comprehensive understanding of the range of analgesic options available.

Recombinant factor IX-Fc fusion protein in severe hemophilia B: Patient-reported outcomes and health-related quality of life

INTRODUCTION

In 2017, all people with severe hemophilia B in Ireland switched to recombinant factor IX Fc fusion protein concentrate (rFIXFc) prophylaxis. Patient-reported outcomes (PROs) and health-related quality of life (HRQoL) are important to evaluate with new treatments.

AIMS

To assess HRQoL in people with severe hemophilia B and their experience after switching to rFIXFc prophylaxis.

METHODS

Participants completed a Patient Reported Outcomes Burden and Experience (PROBE) questionnaire on initiation and following two years of rFIXFc prophylaxis. The PROBE questionnaire has four domains: demographics, general health, haemophilia-specific, and European Quality of Life 5-Dimensions (EQ-5D-5L) questionnaire.

RESULTS

Twenty-three participants completed the questionnaire at both time points. The number of activities where chronic pain occurred and interfered with the activity was reduced by 25% and 33%, respectively (P < .001), following two years of rFIXFc prophylaxis. There was a 9% decrease in chronic pain during the second year of rFIXFc prophylaxis compared to baseline, but the rate remained high, at 74%. A 25% reduction in the number of affected activities of daily living (ADLs) was reported following 2 years of rFIXFc prophylaxis (P = .007). The most common health problems were arthritis, hypertension, anxiety/depression, and gingivitis. The median EQ-5D-5L score was similar following two years of rFIXFc prophylaxis, 0.76 (range, -0.01 to 0.95), compared to 0.77 (range, 0.36-1) at baseline.

CONCLUSION

This study of real-world patient experience using PROs demonstrates a reduction in chronic pain and improvement in ADLs in participants after switching to rFIXFc prophylaxis. It provides important insights into patient-identified health care needs and living with severe hemophilia B.

Improving assessment and management of pain in hemophilia: an Italian Delphi consensus statement

Comprehensive evidence-based guidelines and well-validated assessment scales for pain in people with hemophilia (PwH) are needed. Here, we report 28 statements covering five topics on pain assessment and management in pediatric and adult PwH that were developed by 60 Italian hemophilia specialists during a Delphi consensus process. Overall, a clear consensus was achieved for 19 of the 28 statements. Consensus was reached on all statements on the topic of pain assessment and quality of life (QoL), including the need for regular pain assessment on a quantitative scale, the importance of distinguishing between different pain types, and the need to evaluate the impact of pain on patient QoL. The other four topics concerned acute and chronic pain management in adults and in children. Consensus was reached on statements regarding non-pharmacologic treatment and the use of first-line paracetamol (acetaminophen). There was a lack of consensus regarding the use of non-steroidal anti-inflammatory drugs, cyclooxygenase-2 inhibitors, or opioids.

Changes in pain profile of patients with haemophilia during 1-year follow-up

INTRODUCTION

Patients with haemophilia (PwH) may experience increased sensitivity to pain. Based on the assessment of the somatosensory system, a recent study showed a specific pain profile in PwH when compared to controls by using Quantitative Sensory Testing (QST).

AIM

This study aimed to evaluate the pain profile of affected joints (knee or ankle joints) and a non-affected site (dominant hand) in adult PwH over a 1-year period.

METHODS

Twenty-four PwH (severe haemophilia A = 19, B = 3; moderate haemophilia A = 1, B = 1; age: 52±8 years) and 21 healthy controls (age: 52±12 years) were examined by QST. Both knee or ankle joints and the hand as reference were examined twice with an interval of 1 year in order to assess several detection (DT) and pain thresholds (PT).

RESULTS

Statistically significant altered mechanical (P < .001) and pressure (P < .05) PT were found at affected joints and at a non-affected site in PwH when compared to controls. Mechanical DT showed a significant increase at all assessed sites (e.g., at ankle joints PwH vs. controls at baseline/follow up in mN: 13.9±9.8 vs. 12.0±8.2/19.4±12.4 vs. 13.7±11.1; P < .01) in both cohorts. Nevertheless, changes in most parameters within 1 year occurred similarly in both groups.

CONCLUSION

The statistically significant different QST profile between PwH and controls does not seem to deteriorate further over the course of the year. Thus, under prophylactic treatment, the existing difference in the pain profile between PwH and controls at baseline does not appear to be a progressive process within 1 year.

Haemophilia

Haemophilia A and B are rare congenital, recessive X-linked disorders caused by lack or deficiency of clotting factor VIII (FVIII) or IX (FIX), respectively. The severity of the disease depends on the reduction of levels of FVIII or FIX, which are determined by the type of the causative mutation in the genes encoding the factors (F8 and F9, respectively). The hallmark clinical characteristic, especially in untreated severe forms, is bleeding (spontaneous or after trauma) into major joints such as ankles, knees and elbows, which can result in the development of arthropathy. Intracranial bleeds and bleeds into internal organs may be life-threatening. The median life expectancy was ~30 years until the 1960s, but improved understanding of the disorder and development of efficacious therapy based on prophylactic replacement of the missing factor has caused a paradigm shift, and today individuals with haemophilia can look forward to a virtually normal life expectancy and quality of life. Nevertheless, the potential development of inhibitory antibodies to infused factor is still a major hurdle to overcome in a substantial proportion of patients. Finally, gene therapy for both types of haemophilia has progressed remarkably and could soon become a reality.

Quality of life and its predictors among adult patients with haemophilic arthropathy. An observational study

BACKGROUND

Recurrent hemarthrosis that begin in childhood lead to progressive joint deterioration. Patients with haemophilia have chronic pain, functional disability and a reduced perception of health-related quality of life.

PURPOSE

To analyse the perceived quality of life of adult patients with haemophilic arthropathy and its relationship with pain, joint condition, kinesiophobia and catastrophism.

METHODS

Eighty-three adult patients with haemophilia were included in this multicentre, cross-sectional, descriptive study. Perceived quality of life (36-Item Short Form Health Survey), perceived usual and maximum pain (visual analogue scale), joint condition (Haemophilia Joint Health Score), kinesiophobia (Tampa Scale of Kinesiophobia) and catastrophism (Pain Catastrophizing Scale) were assessed. Sociodemographic, clinical and therapeutic variables and drug consumption for pain control were collected. Descriptive statistics used means and standard deviations. The correlation of quality of life with the dependent variables was calculated with the Pearson correlation test. The differences in quality of life as a function of the binomial variables were calculated with Student's t-test for independent samples.

RESULTS

Physical component of quality of life perceived by patients with hemophilia is lower than Spanish population (30.51 VS 48.85). Regarding the mental component, patients with hemophilia showed higher values (56.07 VS 49.97). Catastrophism correlated (p < .05) with all items of quality of life questionnaire. Kinesiophobia correlated (p < .05) with all items of quality of life except to role-emotional (r = -.18; p > .05). Habitual and maximal joint pain correlated with all items except to role-emotional (r = - .19 and r = - .09, respectively) and mental component score (r = - .16 and r = - .07, respectively). Catastrophism and weekly drug intake were inversely correlated with quality of life. Age was positively correlated with perceived quality of life. There were differences in quality of life as a function of the severity of haemophilia and the intake of drugs for pain control.

CONCLUSIONS

The perceived quality of life of adult patients with haemophilia is worse than that of the Spanish population. Pain, kinesiophobia, catastrophism, haemophilia severity and the intake of pain-control medication influence the quality of life of these patients.

Effects of a non-pharmacological approach for chronic pain management in patients with haemophilia: efficacy of cognitive-behavioural therapy associated with physiotherapy

INTRODUCTION

More than half of adult patients with severe haemophilia (PWH) suffer pain daily, with chronic pain (CP) in more than 15% of cases, thereby reducing their quality of life (QoL). However, there are no evidence-based therapeutic guidelines for pain management.

AIM

To evaluate the effectiveness of a combined protocol based on psychology and physiotherapy in the improvement of CP self-efficacy in PWH with CP. Secondary outcomes are changes in QoL, emotional status, pain and kinesiophobia.

METHODS

In this prospective controlled trial study, recruited patients were allocated either to an experimental group (EG, n = 10) or to a control group (CG, n = 9). EG received interventions over four months: one cognitive-behavioural therapy (CBT) session per month and three home exercise sessions per week. Self-efficacy (Chronic Pain Self-Efficacy Scale), QoL (A36 Hemophilia-QoL), emotional status (Hospital Anxiety and Depression Scale and Rosenberg's Self-esteem Scale), pain (Visual Analogue Scale) and kinesiophobia (Tampa Scale for Kinesiophobia) were assessed at three time points (Week 0, Month 4 and Month 7). The intervention effects were determined with mixed 2-factor ANOVAs.

RESULTS

The EG showed a significant improvement (p < .05) in the control of symptoms and pain management scores on the Self-Efficacy Scale, QoL, self-esteem emotional status, pain and kinesiophobia. The intervention effects remained significant (p < .05) over time for pain management, QoL, pain and kinesiophobia.

CONCLUSION

The non-pharmacological treatment applied based on CBT and physiotherapy showed to be effective in improving CP self-efficacy, QoL and emotional status, while reducing pain and kinesiophobia in PWH with CP.

Pain assessment and management in Italian Haemophilia Centres

BACKGROUND

Although the widespread use of factor VIII/IX replacement therapy has significantly reduced the severity of arthropathy in persons with haemophilia (PWH), some develop degenerative joint changes, associated with significant pain. The aim of this survey was to investigate the management and perception of pain among Italian physicians who treat PWH.

MATERIALS AND METHODS

Between September and October 2017, a questionnaire was distributed to 35 Italian haemophilia treatment centres (60 physicians).

RESULTS

Fifty-three haemophilia specialists completed the survey. We found that there was good agreement (98.1%) on the need to investigate pain at each clinical visit, but there was heterogeneity in the opinions of haemophilia specialists with regards to the availability of validated guidelines (35.8%) and whether pain specialists should be a part of the comprehensive care team in daily clinical practice (58.5%). Haemophilia specialists also agreed pain should be evaluated using a rating scale validated in PWH (88.7%). Pain was mainly managed by the haemophilia specialists themselves, supported by a physiatrist and physiotherapist, while a pain specialist was only involved in 26.4% of cases. The combination of paracetamol with tramadol or codeine was the most common first-line treatment, while cyclo-oxygenase-2 inhibitors, non-steroidal anti-inflammatory drugs, and opioids were less commonly used.

DISCUSSION

There are some unmet needs in Italy regarding pain management for PWH and the management of pain in these patients by haemophilia specialists. There is a lack of evidence-based guidelines for these specialists to use, as well as a reluctance to involve pain specialists. The lack of spontaneous reporting of pain by PWH, despite using pain relief, highlights the need for clinicians to actively ask patients about any pain they may be experiencing.

Functionality and range of motion in patients with hemophilic ankle arthropathy treated with fascial therapy. A randomized clinical trial

BACKGROUND

Hemophilic arthropathy is characterized by loss of function and range motion. Fascial therapy mobilizes the connective tissue, intervening in the state of the injured fascial complex.

OBJECTIVES

The aim of this study is to assess the safety and effectiveness of a fascial therapy treatment in patients with hemophilic ankle arthropathy.

DESIGN

Randomized clinical trial.

METHODS

Sixty-five adult patients with hemophilia from 18 to 65 years of age were recruited. The intervention through fascial therapy lasted 3 consecutive weeks with a weekly session of 45 min each. The dependent variables were frequency of bleeding (selfregistration), ankle range of motion (goniometer) and lower limb functionality (6-Minute Walking Test). Three assess were made: baseline, posttreatment and after follow-up period. ANOVA of repeated measures was performed to compare both groups at the three assess time points. Bonferroni correction has been applied to control the error rate of the significance level.

RESULTS

Improvements were found (p < 0.001) in terms of a reduced frequency of ankle hemarthrosis. Significant differences were found in the experimental group following intervention (p < 0.001), and when comparing baseline and follow-up assessments (p < 0.05) in all variables. The frequency of hemarthrosis (p = 0.04) and functionality (p = 0.01) improved in patients who received manual therapy as compared to the control group.

CONCLUSIONS

Fascial therapy achieves improvements in terms of frequency of hemarthrosis in patients with hemophilic ankle arthropathy. Ankle functionality improved in patients treated with manual therapy. This technique can improve ankle range of motion.

Chronic pain in patients with hemophilia: is it preventable?

: Current management of chronic pain in patients with hemophilia (PWH) focuses on pain relief with analgesics and symptom control. The clinical practice of managing chronic pain in PWH varies considerably across hemophilia treatment centers. Here, we aim to study the appropriate intervention of hemophilic arthropathy for prevention and treatment of chronic pain in PWH. Medline, Embase, Cochrane databases were searched for randomized controlled trials, and the European Hemophilia Therapy Standardization Board, The World Federation of Hemophilia, Nordic Hemophilia Guidelines, American Society of the International Pain Physicians and the Medical and Scientific Advisory Council guidelines were studied through November 2019 for chronic pain in PWH for a narrative review. We found no standardized approach for the prevention and management of chronic pain in PWH. Evidence suggests that prophylactic factor concentrate therapy, programmed exercise and educational intervention may help PWH manage their chronic pain.

Self-Myofascial Release Intervention and Mobile App in Patients With Hemophilic Ankle Arthropathy: Protocol for a Randomized Controlled Trial

Background

Hemophilic ankle arthropathy is manifested by degenerative functional alterations and chronic pain. Myofascial release techniques are used to treat soft tissue adhesions, relieve pain, and reduce tissue sensitivity.

Objective

This study aims to evaluate the safety and efficacy of a protocol using self-myofascial release with a foam roller to be applied in patients with hemophilic ankle arthropathy.

Methods

Patients with ankle arthropathy (N=70) will be recruited, enrolled, and assigned to one of two groups—experimental or control—in a 1:1 allocation ratio. Patients will be recruited from 5 centers in different regions of Spain. Patient data will be collected at baseline, posttreatment, and follow-up. The primary outcome will be frequency of ankle joint bleeding (self-reported). The secondary outcomes will be ankle range of motion (measured with a digital goniometer); joint pain (measured with a visual analog scale and an algometer); joint status (measured using the Hemophilia Joint Health Score); muscle strength (measured with a dynamometer); functionality of lower limbs (measured using the 6-minute walking test); activity (self-reported); and muscle flexibility (measured using the fingertip-to-floor test). The treatment program includes 11 exercises that must be administered bilaterally. A mobile app will be developed where each patient will be able to observe the exercises to be carried out. Each session will last 15 minutes with 5 physiotherapy sessions per week for a period of 3 months. It is expected that patients with hemophilia who receive the foam roller intervention will show improvement in mobility, pain, and status of the ankle joint; muscle strength; and function in the lower extremities.

Results

The study has been approved by the institutional review board of the University of Murcia. Patient recruitment will begin in September 2020, and the intervention period will last until June 2021. Data collection will take place between September 2020 and October 2021.

Conclusions

This protocol describes a randomized clinical trial to examine the safety and efficacy of a self-myofascial release intervention using a foam roller in patients with hemophilic ankle arthropathy.

Physiotherapy interventions for pain management in haemophilia: A systematic review

PURPOSE

Approximately 35%-50% of people with haemophilia (PWH) report living with chronic musculoskeletal pain. Although exercise based rehabilitation is effective for pain in other arthritises, there are no published guidelines for management of chronic pain in PWH. This review aims to evaluate and appraise the current evidence of effectiveness of physiotherapy interventions on (a) pain intensity, (b) quality of life (QoL) and (c) function in PWH.

METHODS

A systematic review of five databases AMED and CINAHL, EMBASE and MEDLINE and PEDro, as well as trial registries, grey literature and hand searching key journals was completed. Included studies were critically appraised and evaluated for risk of bias. The GRADE approach was used to rate the quality of the evidence.

RESULTS

Nine trials consisting of 235 participants met the inclusion criteria. All studies had an overall risk of bias with low methodological quality. Meta-analysis was not possible due to heterogeneity across trials. Studies comparing a range of physiotherapy interventions against no intervention showed no clear beneficial effect on pain intensity or QoL. Only one study, investigating hydrotherapy or land-based exercise against control, showed positive effect for pain intensity, but rated very low on GRADE assessment. Studies comparing one physiotherapy intervention against another showed no clear benefit on pain intensity, QoL or function. LASER with exercise and hydrotherapy were shown to have some positive effects on pain intensity, but no clear benefit on function.

CONCLUSIONS

At present, there is limited evidence for the use of physiotherapy interventions in addressing the issue of pain in PWH. Better designed trials with higher quality and explicit methodology along with user involvement are needed to assess the efficacy of any proposed intervention.

Gynaecological issues in women with bleeding disorders: CSL Behring Symposium

The symposium focused on issues around surgery, ovulation bleeding, health-related quality of life (HRQoL) and pelvic pain in women with bleeding disorders.

Surgery

Young women with congenital bleeding disorders, especially those with severe forms, are more likely to experience gynaecological and obstetric disorders than unaffected women. Surgery may be required to manage heavy menstrual bleeding (HMB), ovulatory bleeding, endometriosis and delivery. Major surgery should be undertaken only in hospitals with a haemophilia centre and 24-hour laboratory capability. Correction of haemostasis, either by desmopressin, coagulation factor or platelet transfusion, is essential for a successful outcome of surgery. Management of pregnancy requires a multidisciplinary approach; the mode of delivery is based on the consensus of gynaecologist and haematologist, and with respect to the patient’s diagnosis.

Ovulation bleeding

Women with bleeding disorders are at risk for excessive gynaecological bleeding associated with menstruation, ovulation, pregnancy and delivery. Ovulation bleeding is associated with the rupture of ovarian cysts and causes abdominal pain; complications include haemoperitoneum, fertility problems and ovarian torsion. Management includes hormonal and haemostatic therapies, in combination if necessary, and surgery as a last resort. Current management is based on experience in a relatively small number of cases and more clinical data are needed.

Health-related quality of life

In addition to experiencing joint and tissue bleeds, women experience psychosocial and medical issues associated with menstruation, pregnancy, labour and delivery. HMB has the greatest impact, and is associated with impaired HRQoL in almost all and dissatisfaction with the burden of treatment. There is a need for focused psychosocial support and a specific tool for the assessment of HRQoL in women with bleeding disorders.

Pelvic pain

Gynaecological causes of pelvic pain in women with bleeding disorders include dysmenorrhoea, mid-cycle pain, bleeding into the corpus luteum and endometriosis. There is no correlation between bleeding tendency and endometriosis severity; however, screening for a bleeding disorder should be considered. Pharmacological management may be hormonal or non-hormonal. Gonadotrophin-releasing hormone agonists offer an alternative to surgery for women with severe bleeding disorders who have endometriosis. Paracetamol is the preferred early analgesic option. Endometrial ablation controls heavy bleeding and pelvic pain but is not recommended for women with large fibroids or a large endometrial cavity. Hysterectomy is an option of last resort. Education for health professionals should include raising awareness about the management of pain in women with bleeding disorders.

Effectiveness of hypnosis for pain management and promotion of health-related quality-of-life among people with haemophilia: a randomised controlled pilot trial

Joint deterioration and associated chronic pain are common among people with haemophilia (PWH), having an impact on quality-of-life. Though non-pharmacological strategies are recommended, psychological interventions to promote pain control and quality-of-life have scarcely been tested in haemophilia. This randomised controlled pilot trial aimed to assess feasibility, acceptability and effectiveness of hypnosis for pain management and promotion of health-related quality-of-life (HRQoL) among PWH. Twenty adults were randomised either to four weekly hypnosis sessions plus treatment-as-usual (experimental group; EG) or treatment-as-usual only (control group; CG). Participants completed sociodemographic and clinical assessment, measures of pain, HRQoL and emotional distress before (T1) and after (T2) intervention. Changes were analysed by calculating the differences between T1 and T2, and the groups were compared through independent-sample t tests (or chi-squared). Retention rates (90%) and analysis of patient satisfaction showed good acceptability and feasibility of the intervention. The EG (n = 8) had a higher reduction on pain interference than the CG (n = 10) (d = −0.267). A higher improvement on HRQoL (EQ-5D index: d = 0.334; EQ-5D VAS: d = 1.437) and a tendency towards better haemophilia-related quality-of-life (A36-Hemofilia QoL) were also evident in the EG. This is the first study showing the effectiveness of hypnosis to reduce pain interference and promote HRQoL among PWH.

[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.

Pain Prevalence, Characteristics, and Impact Among People with Hemophilia: Findings from the First Portuguese Survey and Implications for Pain Management

Background

Hemophilia is a rare disorder characterized by spontaneous bleeding, with pain being a critical aspect. However, a systematic assessment of hemophilia-related pain in Portugal has never been conducted.

Objective

To understand the pain experience among Portuguese people with hemophilia (PWH) by describing its prevalence, characteristics, and impact and uncovering intervention needs in the realm of hemophilia-related pain care.

Methods

A cross-sectional observational survey, with age-adapted versions of questions concerning pain, emotional distress, and quality of life, was answered by 104 adults, 21 children/teenagers (10–17 years), and 19 children (1–9 years).

Results

Pain was reported by 82 (78.8%) adults, 16 (76.2%) children/teenagers, and 13 (68.4%) children, with 65 (62.5%), 13 (61.9%), and eight (42.1%) of them reporting pain lasting more than three months, respectively. The mean number of pain locations (SD) was 5.23 (3.95) for adults, 4.13 (3.48) for children/teenagers, and 3.15 (1.99) for children age 1–9 years, with lower limbs pain causing the greatest negative impact. More frequent pain-triggering factors were physical effort/movements (61, 74.4%) for adults and hemarthrosis for younger groups (children/teenagers: 14, 87.5%; children: 9, 69.2%). Bleeds yielded the highest mean pain intensity (adults: M [SD] = 5.67 [2.09]; children/teenagers: M [SD] = 5.69 [2.15]). Adults with pain revealed more anxiety (odds ratio [OR] = 1.698, P = 0.003) and depression (OR = 1.961, P = 0.025) and lower quality of life (OR = 0.928, P = 0.001).

Conclusions

The current findings highlight the high prevalence, duration, and frequency of pain at all ages, its potentially simultaneous acute and chronic nature, its likelihood to affect multiple locations concurrently, and its detrimental impact. Important insights concerning intervention needs are presented, ultimately contributing to the improvement of hemophilia-related pain management and patient care.

A new measure to assess pain in people with haemophilia: The Multidimensional Haemophilia Pain Questionnaire (MHPQ)

People with haemophilia (PWH) experience acute pain during joint bleeds and might develop chronic pain due to joint degeneration. However, there is a lack of standardized measures to comprehensively assess pain in PWH. This study aimed to develop a multidimensional questionnaire for haemophilia-related pain, the Multidimensional Haemophilia Pain Questionnaire (MHPQ), and to present initial validation data among adults.The questionnaire distinguishes between acute/chronic pain and queries about pain locations, duration, frequency, triggering factors, intensity, interference, strategies, specialists for pain management and satisfaction with treatment. An initial version was tested with 16 patients to ensure item comprehensibility and face validity. The final version was answered by 104 adults, with 82 (78.8%) reporting haemophilia-related pain in the previous year (mean age = 43.17; SD = 13.00). The non-response analysis revealed good item acceptability. Exploratory and confirmatory factor analysis (EFA/CFA), reliability (internal consistency, test-retest, inter-item and item-total correlations) and convergent validity were analysed for the intensity and interference dimensions of the questionnaire. A combined EFA with these two constructs supported a 2-factor structure distinguishing intensity (α = 0.88) from interference items (α = 0.91). CFA was tested for the interference dimension, demonstrating suitability for this sample. Item-total correlations were >0.30 on both dimensions and most inter-item correlations were <0.70. Test-retest reliability (n = 42) was good for intensity (r = 0.88) and interference (r = 0.73), and convergent validity was confirmed for most hypotheses (r>0.30).This questionnaire is a comprehensible tool, achieving a thorough assessment of relevant pain dimensions. The MHPQ can help guide treatment recommendations by highlighting relevant topics and contributing to more effective, integrated treatments.

Joint disease in haemophilia: Pathophysiology, pain and imaging

Haemarthroses cause major morbidity in patients with haemophilia. Blood has devastating effects on all joint components, resulting in synovitis, osteochondral degeneration and ultimately end-stage haemophilic arthropathy. Key players in this process are iron and inflammation. Preventing joint bleeds is of utmost importance to maintain joint health as targeted therapies directed against blood-induced inflammation and iron-mediated processes are lacking. Joint bleeds result in acute pain as well as chronic pain due to synovitis or arthropathy. Acute pain originates from nociceptors activated by tissue damage. In chronic inflammation, central and peripheral sensitization of nociceptors might occur resulting in chronic pain. This also triggers a series of brain disorders such as emotional fear, anxiety, mood depression and impairment of cognitive functions. Treatment of haemophilia-related pain not only consists of analgesics, but also of exercise, education and in selected cases antidepressants and anticonvulsants. For objective assessment of joint structural outcome and detecting earlier changes of haemophilic arthropathy, both ultrasound (US) and magnetic resonance (MR) imaging have shown valuable. Both can be considered equally able to reveal signs of disease activity. MR imaging is able to visualize haemosiderin deposition and is more comprehensive in depicting osteochondral changes. Disadvantages of MR imaging are the duration of the examination, evaluation of a single joint at a time, costs and may require sedation, and it may need intraarticular contrast injection to depict initial osteochondral changes with accuracy. As such, US is a more useful screening tool and can be used for repeated follow-up examinations.

The Impact of Bleeding Disorders on the Socioeconomic Status of Adult Patients

The impact of inherited bleeding disorders on the socioeconomic status (SES) of affected individuals is not clear. The SES of adult patients with congenital bleeding disorders (PWBD) from a centre in Germany (age 42.3 ± 15.0 years) was compared to that of a gender- and age-matched control group of patients with thrombophilia or a thrombotic event (PWT). Patients completed a questionnaire including aspects of SES, impact of the disease on their lives, and health-related quality of life (HRQoL). Forty-five patients were enrolled in each group; 71 % of PBWD had a severe form of the bleeding disorder (FVIII/IX activity < 1 % or VWD type 3), and 60 % of all PWBD were treated on-demand. PWBD had a lower monthly income (p = 0.029) and a worse occupational status (p = 0.047) than PWT, but there was no difference regarding the project-specific SES index. PWBD also reported a worse HRQoL in the physical summary component score of the SF-36 (p < 0.001). More PWBD (69.8 %) reported a high impact of the disease on their lives than PWT (33.3 %, p < 0.001). In summary, PWBD had a worse occupational status, monthly income, health behaviour, HRQoL, and impact of the disease on their lives compared to PWT, but not a significantly different SES in general.

[Homeopathic Medicine Reduces Pain and Hemarthrosis in Moderate and Severe Hemophilia: A Multicentric Study]

BACKGROUND

Hemarthrosis is a common clinical presentation of patients with severe and moderately severe hemophilia. Severe pain, swelling, and loss of function involving knee, ankle, elbow, and shoulder joints are commonly seen. In India, except for paracetamol and some non-steroidal anti-inflammatory drugs (NSAIDs), opiate analgesics are not easily available even in the mainstay of treatment; i.e., factor concentrates are also not available regularly. Hence, there is an unmet need for exploring alternative management strategies in this condition in India.

OBJECTIVE

To assess the effect of homeopathic medicines on pain and acute hemarthrosis in hemophilia when factor concentrates are not available and paracetamol in adequate doses proves inadequate.

PATIENTS

343 patients with hemophilia (PWH) from Nashik, Mumbai, and Surat presenting with hemarthrosis were prescribed homeopathic medicines in addition to paracetamol and RICE (rest, immobilization, cold application, and elevation). They were assessed using standard techniques.

RESULTS

1,679 episodes of hemarthrosis in major joints were encountered between December 2007 and March 2014, in 343 patients. In 1,580 of the 1,679 hemarthrosis episodes (94.1%), bleeding/inflammation was arrested and pain relieved with homeopathic medication. Additional factor concentrate was required in 99 patients (4.48%). The mean pain score improved from 6.88 ± 2.118 to 1.5 ± 0.34 over 6-24 h following the homeopathic medicines (p < 0.0001). The swellings were also substantially reduced (p < 0.001). The number of joint bleeds per month was reduced significantly under the influence of therapy (p < 0.0001), showing the long-term disease-modifying effect of the treatment.

CONCLUSION

Homeopathic medicines without factor concentrates appeared to reduce bleeding and pain in PWH presenting with hemarthrosis and could have influenced the long-term frequency of bleeding.

Health-Related Quality of Life and Psychological Aspects of Adults With Hemophilia in Iran

Hemophilia causes bleeding that may affect patients’ psychological aspects and quality of life. This study aims to evaluate the impact of psychological aspects and pain on health-related quality of life (HRQoL) in adult patients with hemophilia. This cross-sectional study was conducted on 103 patients with hemophilia. Data were collected using hemophilia-specific quality of life, Depression Anxiety Stress Scales, and pain visual analogue scales. Data were analyzed using correlation coefficients, analysis of covariance, and regression analysis. The results showed that 71.7% of patients with hemophilia experienced pain on the study day. The mean score of HRQoL of patients with hemophilia was 51.09 (standard deviation = 19.37). Moreover, 57.4%, 64.6%, and 44.6% of the patients had mild to severe depression, anxiety, and stress, respectively. In addition, a significant association was observed between HRQoL and depression, anxiety, and severity of pain. In the regression model, 48% of changes in HRQOL were explained by the study variables, with the severity of pain and depression being significant predictors. Therefore, attention should be paid to these aspects to improve patients’ quality of life and psychosocial health.

Pain therapy in haemophilia in Germany

One of many challenges in the treatment of persons with haemophilia is the selection and application of appropriate pain-relieving therapies. The current situation of pain management for persons with haemophilia in Germany was evaluated using a survey with the intention of identifying potential areas for improvement. Results of 685 respondents showed that 86% experienced episodes of pain and that pain was already present in 66% of children and adolescents. Joint pain was the most common type of pain (92%), remarkably so even in 80% of young patients. Half of the patients received pharmacological therapy for the pain and 46% of the patients received physiotherapy. Priority and sequence of the contacted physicians and therapists for diagnosis and therapy is described. Satisfaction with pain therapy was expressed by 56% of participants and 18% felt their pain not treated sufficiently.

The results of the survey will be used to develop measures for improvement of long-term care of haemophilia patients regarding pain therapy.

Wishes and worries of haemophilia patients

Haemophilia care in Germany has achieved a high level and enables the majority of patients to lead a largely normal life. The Bluter Betreuung Bayern e.V. (BBB) aims to improve health care and support for haemophilia patients. A questionnaire has been developed by BBB representatives to evaluate unmet medical needs from the patient perspective. It was sent to 290 haemophilia patients and/or their parents in Bavaria in November 2015. The response rate was 51.4 %: 66 children aged < 15 years (66.7 % severe), 30 patients 15–24 years (66.7 % severe), 26 patients 25–44 years (80.8 % severe), 24 patients > 44 years (95.8 % severe). Prophylactic therapy in patients with severe haemophilia aged < 25 and ≥ 25 years is given “always” in ≥ 80 % and > 60 %, respectively. Substitution therapy is mostly uncomplicated. Satisfaction with medical care is high. Chronic pain is a problem with increasing age. Patients aged 25–44 years worry least regarding future health, safety and availability of factor products, patients > 44 years most. Overall, 80–100 % of the patients from all age groups are interested in information on the current state of science. Offers of the BBB for psychosocial support in addition to the medical care seem to be helpful and needed in all age groups.

Internal consistency and item-total correlation of patient-reported outcome instruments and hemophilia joint health score v2.1 in US adult people with hemophilia: results from the Pain, Functional Impairment, and Quality of life (P-FiQ) study

BACKGROUND

The Pain, Functional Impairment, and Quality of Life study was an observational, cross-sectional assessment of the impact of pain on functional impairment and quality of life in adult people with hemophilia (PWH) of any severity in the USA who experience joint pain and/or bleeding.

OBJECTIVE

To assess internal consistency (IC) and item-total correlation (ITC) of assessment tools used in the Pain, Functional Impairment, and Quality of Life study.

METHODS

Participants completed 5 patient-reported outcome instruments (EQ-5D-5L with visual analog scale, Brief Pain Inventory v2 Short Form [BPI], International Physical Activity Questionnaire [IPAQ], Short Form 36 Health Survey v2 [SF-36v2], and Hemophilia Activities List [HAL]) and underwent an optional physiotherapist-administered musculoskeletal exam (Hemophilia Joint Health Score v2.1) during routine visits. Reliability assessment included IC and ITC of each instrument.

RESULTS

A total of 381 adult PWH (median age, 34 years) were enrolled. Participants were predominantly white/non-Hispanic (69.2%); 75% had congenital hemophilia A, and 70.5% had severe hemophilia. A total of 310 subjects reported bleeding within the past 6 months (mean [SD] number of bleeds, 7.1 [13.00]). IC was generally high across the instruments employed (Cronbach's alpha 0.79-0.98) with the exception of HAL use of transportation (0.58) and IPAQ total physical activity (0.51). ITC was high (Pearson's product-moment correlation coefficient >0.20) for all items except the "vigorous intensity activities" item of IPAQ, which was applicable to less than one-third of participants. The ITCs were generally highest in domains/scores that measured the functional consequences of hemophilic arthropathy on mobility and pain.

CONCLUSION

The demonstrated reliability (IC/ITC) of the patient-reported outcome instruments and Hemophilia Joint Health Score v2.1 support a role for these instruments in evaluating adult PWH in US clinical and research settings.

Effectiveness of two psychological interventions for pain management, emotional regulation and promotion of quality of life among adult Portuguese men with haemophilia (PSY-HaEMOPEQ): study protocol for a single-centre prospective randomised controlled trial

INTRODUCTION

Haemophilia is a bleeding disorder associated with significant pain, emotional distress, quality of life (QoL) impairment and considerable healthcare costs. Psychosocial health and effective pain management are considered essential end points for optimal haemophilia care, but there is a significant gap in evidence-based treatments targeting these outcomes in people with haemophilia (PWH). Psychological interventions are cost-effective in promoting emotional well-being, QoL and pain control, although these have been scarcely used in haemophilia field. This investigation aims to evaluate the effectiveness of two psychological interventions for pain management, emotional regulation and promotion of QoL in PWH.

METHODS AND ANALYSIS

This is a single-centre parallel randomised controlled trial conducted at a European Haemophilia Comprehensive Care Centre in Portugal, with five assessment points: baseline (T0), postintervention (T1), 3 (T2), 6 (T3) and 12 (T4) months follow-up. Eligible adult males, with moderate or severe haemophilia A or B will be randomised to experimental (EG) or control (CG) group. Intervention is either cognitive-behavioural therapy (EG1) or hypnosis (EG2), both consisting of four weekly sessions following standardised scripts delivered by trained psychologists. Randomisation will be computer generated, allocation concealment will be guaranteed and outcome assessors will be blind to EG/CG allocation. Main outcomes are pain and haemophilia-related QoL and secondary outcomes include clinical (clotting factor replacement consumption, joint bleeding episodes, analgesic intake) and psychological (pain coping strategies, anxiety, depression, illness perceptions) variables, functional assessment of the joints, inflammatory biomarkers (cytokines, high-sensitivity C reactive protein) and white blood cell count.

ETHICS AND DISSEMINATION

This study was approved by the competent authorities and all procedures will comply with international ethical guidelines for clinical studies involving humans. Written informed consent will be obtained from all participants. The dissemination plan includes peer-reviewed scientific publications, conference participation and web and media coverage.

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.
