Effectiveness of emicizumab in preventing bleeding events in severe and moderate hemophilia A: A single-center experience in Bangladesh. EJHAEM 2024; 5:39-46. [PMID: 38406515 PMCID: PMC10887364 DOI: 10.1002/jha2.832] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 11/22/2023] [Indexed: 02/27/2024]
Abstract
Emicizumab is a monoclonal antibody that bridges activated factor IX (FIX) and factor X (FX) to replace the function of missing activated factor VIII (FVIII) in hemophilia A patients irrespective of FVIII inhibitor status. This study assessed the effectiveness of emicizumab in preventing bleeding episodes in patients with hemophilia A. This observational study included patients with moderate to severe hemophilia A who were undergoing episodic FVIII replacement therapy. The primary endpoint was the difference in annualized bleeding rates (ABR) and the secondary endpoint was the difference in Hemophilia Joint Health Score (HJHS) before and after emicizumab prophylaxis. A total of 30 male hemophilia patients were included, the mean age was 16.7 (SD: ±8.1) years, and most of them had moderate hemophilia A [63.3%]. Before prophylaxis, the median ABR was 48 (interquartile range [IQR]: 35-60), and 93.3% of patients had ABR greater than eight, whereas after prophylaxis the median ABR decreased significantly (median [IQR]: 0 [0.0-0.4], p < 0.001), and 56.7% had zero bleeds. ABR was not significantly different in patient with and without FVIII inhibitors. The HJHS scores significantly improved after prophylaxis (10 vs. 2.5, p < 0.001). The bleeding events were reduced significantly (23 vs. 0.0, p < 0.001), and zero new target joints were reported after prophylaxis. Most of the patients [93.3%] did not face any serious adverse events after prophylaxis. Emicizumab prophylaxis was associated with a significantly lower rate of bleeding events among participants with hemophilia A, regardless of inhibitor status.

Zhang L, Zhang P, Chen W. Treatment regimens, patient reported outcomes and health-related quality of life in children with moderate and severe hemophilia A in China: using real-world data. Orphanet J Rare Dis 2023; 18:232.

Abstract
BACKGROUND Prophylaxis therapy for children with moderate and severe hemophilia A (HA) is the optimal treatment regimen. The real-world treatment regimens, patient-reported outcomes, and health-related quality of life (HRQoL) in children with moderate and severe HA in China are less known. OBJECTIVE This study aimed to describe real-world treatment regimens and evaluate the association of treatment regimens with comprehensive patient-reported outcomes including bleeds, chronic pain, target joints, disability, and HRQoL in children under 18 years old with HA in China. METHODS Real-world data of a nationwide online cross-sectional survey in 2021 and patients' coagulation factor utilization data from self-management records from 2020 to 2021 were merged. 373 eligible children were included and categorized by treatment regimens according to the Chinese guideline: on-demand, short-term prophylaxis, and long-term prophylaxis treatment. RESULTS Currently, in China, 4.8% of children with HA are receiving full-dose long-term prophylaxis treatment. Prophylaxis treatment was a significant positive predictor of better patient-reported outcomes and HRQoL. For children with prophylaxis treatment, there were significantly fewer annual bleeds (p < 0.001), lower frequency of chronic pain(p < 0.001), and higher health utility scores(p < 0.01) and EQ-VAS scores(p < 0.05) than children with on-demand treatment. CONCLUSION Accessible long-term prophylaxis treatment should be promoted for children with moderate and severe HA in China and regular monitoring of their outcomes and HRQoL should be carried out.

Abstract
INTRODUCTION Improvements in haemophilia treatment over the last decades resulted in increased life expectancy in persons with haemophilia (PWH). AIM We conducted a systematic review and meta-analysis to examine all-cause mortality and causes of death among PWH. METHODS We systematically searched EMBASE, MEDLINE, Web of Science, CINAHL and Cochrane central register of controlled trials from inception through March 15, 2021. Studies that reported a mortality estimate of PWH compared with the general population and/or reported causes of death were included. Random-effects meta-analysis with inverse variance method was used to obtain pooled estimates. We stratified the analysis by the year of cohort entry (before 2000 vs after 2000). RESULT Of the 4769 studies identified, 52 met the eligibility criteria. The pooled all-cause standardized mortality ratio (SMR) from 9 studies in PWH was 1.93 (95% CI 1.38-2.70; I2 = 97%). The pooled SMRs before and after the year 2000 were 2.40 (95% CI 1.92-3.00; I2 = 87%) and 1.20 (95% CI 1.03-1.40; I2 = 62%), respectively. Before the year 2000, 31.2% deaths occurred due to HIV followed by haemorrhage (26.0%), cardiovascular disease (18.2%), liver disease (9.0%), and cancer (8.9%). Fewer (13.9%) deaths were attributable to HIV after the year 2000 with the proportion of deaths due to haemorrhage remaining unchanged. CONCLUSION With treatment advances, mortality in PWH has declined over the last few decades approaching that of the general population. However, haemorrhage remains a leading cause of death requiring further attention.

Abstract
Intracranial hemorrhage (ICH) is a severe complication that is relatively common among hemophilia patients. This systematic review aimed to obtain more precise estimates of ICH incidence and mortality in hemophilia, which may be important for patients, caregivers, researchers and health policy-makers. PubMed and EMBASE were systematically searched using terms related to "hemophilia" and "intracranial hemorrhage" or "mortality". Studies that allowed calculation of ICH incidence or mortality rates in a hemophilia population of at least 50 patients were included. We summarized evidence on ICH incidence and calculated pooled ICH incidence and mortality in three age groups: (1) persons of all ages with hemophilia, (2) children and young adults below 25 years of age with hemophilia and (3) neonates with hemophilia. Incidence and mortality were pooled with a Poisson-Normal model or a Binomial-Normal model. We included 45 studies that represented 54 470 patients, 809 151 person-years and 5326 live births of hemophilia patients. In persons of all ages, the pooled ICH incidence and mortality rates were 2.3 (95% CI 1.2-4.8) and 0.8 (95% CI 0.5-1.2) per 1000 person-years, respectively. In children and young adults, the pooled ICH incidence and mortality rates were 7.4 (95% CI 4.9-11.1) and 0.5 (95% CI 0.3-0.9) per 1000 person-years, respectively. In neonates, the pooled cumulative ICH incidence was 2.1% (95% CI 1.5-2.8) per 100 live births. ICH was classified as spontaneous in 35-58% of cases. Our findings suggest that ICH is an important problem in hemophilia that occurs among all ages, requiring adequate preventive strategies.

Abstract
INTRODUCTION Emicizumab is a bispecific antibody exerting cofactor function of FVIIIa irrespective of the presence of FVIII inhibitors. Long-term data of phase 1/2 and phase 3 studies have been accumulated. Various questions such as indicated patients, ITI, application to PUPs, hemostatic treatment including surgeries, and emicizumab-related morbidity remain to be solved. AREAS COVERED The review describes the mode of action, data from pre-/post-marketing and ongoing clinical studies according to PubMed search and our own works. EXPERT OPINION For patients with a persistent inhibitor, emicizumab is a definite therapeutic option, although the possibility of BPAs-associated thromboembolic/TMA events raises concerns. The use of ITI together with emicizumab prophylaxis is being examined in clinical trials. For non-inhibitor, especially pediatric patients, emicizumab prophylaxis can be an option. Outcome assessment 'beyond ABR' such as joint health, physical/mental activity, QOL is required. Furthermore, continuous data collection for emicizumab-related adverse events and morbidity would be recommended.

Abstract
BACKGROUND Treatment of patients with hemophilia has advanced over the past decades, but it is unknown whether this has resulted in a normal life expectancy in the Netherlands. OBJECTIVE This observational cohort study aimed to assess all-cause and cause-specific mortality in patients with hemophilia in the Netherlands between 2001 and 2018 and to compare mortality and life expectancy with previous survival assessments from 1973 onward. PATIENTS/METHODS All 1066 patients with hemophilia who participated in a nationwide survey in 2001 were followed until July 2018. RESULTS Information on 1031 individuals (97%) was available, of whom 142 (14%) deceased during follow-up. Compared with the general Dutch male population, mortality of patients with hemophilia was still increased (standardized mortality ratio: 1.4, 95% confidence interval: 1.2-1.7). Intracranial bleeding and malignancies were the most common causes of death. Estimated median life expectancy of patients with hemophilia was 77 years, 6 years lower than the median life expectancy of the general Dutch male population (83 years). Over the past 45 years, death rates of patients with hemophilia have consistently decreased, approaching the survival experience of the general population. Over the past decades, mortality due to human immunodeficiency virus and hepatitis C virus infections has decreased, death due to intracranial hemorrhages has increased, and death due to ischemic heart disease has remained consistently low over time. CONCLUSIONS Survival in patients with hemophilia in the Netherlands has improved over time but is still lower than that of the general population.

Abstract
Against a background of a rapidly evolving treatment landscape, a contemporary, evidence-based consolidated understanding of mortality in people with congenital hemophilia A (PwcHA) is lacking. This systematic literature review examines the available data on mortality and causes of death in PwcHA to enable a better understanding of fatalities in PwcHA and evaluate the impact of new treatment paradigms on mortality. A systematic literature review of observational studies was conducted by searching Medline, Embase, and clinical trials registries for articles published from January 2010 to March 2020, using the search terms: hemophilia A (HA), mortality, cause of death. Interventional studies, studies not reporting fatalities, and those reporting only on hemophilia B, acquired HA, or mixed other coagulopathies were excluded. Overall, 7818 unique records were identified and 17 were analyzed. Of these, six reported mortality rates and five reported mortality ratios. Mortality generally decreased over time, despite a spike associated with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) infection in the 1980s and 1990s. Mortality was strongly correlated with age and hemophilia severity. People with hemophilia had a raised mortality risk compared with the general population, particularly in severe hemophilia, and when infected with HIV or HCV. Causes of death varied across populations, countries, and time in 15 identified studies; however, incomplete and heterogeneous reporting limits evidence. Hemorrhage, HIV, HCV, and hepatic disease were the leading causes of death. A unified approach to reporting mortality and cause of death is needed to understand mortality in PwcHA as treatments continue to advance.

Abstract
Emicizumab is a bispecific antibody that recognizes FIX(a)/FX, and mimics FVIIIa cofactor activity. Due to its unique characteristics including longer half-life and subcutaneous injectability, treatment for haemophilia A dramatically improved regardless of the presence of FVIII inhibitor. Protection from pathological change in joints, avoidance of inhibitor development and intra-cranial haemorrhage could be expected by introduction of emicizumab in early childhood. Applications in mild/moderate patients should be also considered. Clinical assessment tool should be standardized; however, since there are limitations to conventional ABR-based assessment. Laboratory monitoring is another practical issue due to the mode of action of emicizumab. Chromogenic assays and global assays could be utilized. The other emicizumab-related practical issue is immune tolerance induction for the inhibitor patients, since ITI remains the only effective means to inhibitor eradication. With the recently introduced Atlanta protocol, emicizumab prophylaxis is given in combination with 50-100 IU/kg FVIII three times a week. A single manuscript has been published, and multiple clinical trials are open to address the efficacy of this strategy. Whether the Atlanta protocol will be fully embraced is yet to be seen, but there is widespread consensus about attempts to tolerize every haemophilia A patient with an inhibitor.

Abstract
OBJECTIVE This study aims to investigate the distribution, clinical characteristics and outcome of inherited coagulation disorders (ICD) in Turkish children. SUBJECTS AND METHODS Data from all children (age<18 years) with ICD examined in our center were retrospectively reviewed. RESULTS There were 403 children with ICD (233 males and 170 females) with a median age of four years at diagnosis. The percentages of von Willebrand disease (vWd), hemophilia and rare bleeding disorders (RBD) were 40 %, 34 % and 26 %, type-1, type-2 and type-3 vWd were 63 % 17 % and 20 %, hemophilia A and B were 84 % and 16 %, and severe, moderate and mild hemophilia were 48 %, 30 % and 22 %, respectively. Factor VII and FXI deficiencies were the most prevalent, comprising 56 % and 22 % of all children with RBD, respectively. Parental consanguinity rates were 72 % in type-3 vWd and 61 % in severe RBD. The overall prevalence of gastrointestinal bleedings was 4.5 % (18/403), intracranial bleeding (ICB) was 4.96 % (20/403), mortality from ICB was 30 % (6/20) and the overall mortality rate was 1.49 % (6/403). No life-threatening bleeding was seen during regular prophylaxis. Chronic arthropathy prevalence in severe hemophilia was 8 % with primary prophylaxis and 53 % with demand therap. Inhibitor prevalence was 14 % in hemophilia-A and 5 % in hemophilia-B. CONCLUSIONS These data show that vWd is the most common ICD, type-3 vWd and RBD are prevalent due to frequent consanguineous marriages and diagnosis of ICD is substantially delayed in Turkish children. Prophylactic replacement therapy prevents occurrence of life-threatening bleedings and reduces the development of hemophilic arthropathy.

Abstract
BACKGROUND Intracranial hemorrhage (ICH) is a life-threatening condition in children. Inherited bleeding disorders (IBD) have high risk of ICH. AIM This single center study aims to identify the incidence, risk factors, and neurological outcome of ICH in children who suffer from IBD. METHODS From 2005 to 2017, 241 children with IBDs from Nanfang hospital, Department of Pediatrics, were evaluated. The ICH episodes were identified by medical history, general physical examination, detailed neurological examination, and computed tomographic or magnetic resonance imaging examination. The risk factors, location of ICH, management strategies, and outcome were noted. RESULTS ICH was confirmed in 54/241 (22.4%) children with IBD among them 52/54 (96.2%) (95% confidence interval [CI], 91.1%-99.9%) were hemophilia A and hemophilia B patients. The overall risk of ICH among children with IBD was 22.4% (95% CI, 17.2%-27.8%). The median age of ICH was 30 months (0 to 204) and 18/54 (33.3%) (95% CI, 20.3%-46.3%) children had an ICH in the first year of life. Twenty-eight of 52 (53.8%) hemophilic children with ICH were assessed for inhibitor of FVIII and FIX. Nine of 28 (32%) hemophilic children with inhibitor developed the ICH. Six of 52 (11.5%) (95% CI, 2.6%-20.5%) hemophilic children had multiple episodes of ICH in which 4 were inhibitor positive. Thirteen of 54 (24%) (95% CI, 12.3%-35.9%) had positive family history of IBD. Twenty-two (36%) (95% CI, 23.7%-48.5%) of 61 ICH episodes were caused by trauma and 39 (63.9%) (95% CI, 51.5%-76.3%) were nontrauma related. Subdural hematoma was most frequently observed. Mortality risk from ICH in children with IBD was 5/54 (9.2%) (95% CI, 1.3%-17.2%). Eleven (22.4%) (95% CI, 10.3%-34.6%) of 49 survivors had known neurological squeal, whereas 38 (77.5%) (95% CI, 65.4%-89.7%) had no documented evidence of neurological impairment. CONCLUSIONS Hemophilia is the most common IBD and most frequently associated with ICH. Risk and consequences of ICH in IBD were high during the first year of life while in older children better outcome may be expected. The optimal management of ICH depends on immediate recognition and prompt replacement therapy.

Abstract
INTRODUCTION Brazil has the fourth largest world population of patients with haemophilia. However, mortality rates in this population are unknown. AIM To analyse mortality and its causes in Brazilian patients with haemophilia from 2000 to 2014. METHODS The number of deceased patients with haemophilia and causes of death were obtained from the Brazilian National Mortality Information System (SIM), according to the 10th International Classification of Diseases (ICD-10). Standardized mortality ratios (SMR) were calculated to estimate the rate of overall death of patients with haemophilia relative to that of the Brazilian general male population. RESULTS A total of 784 deaths were identified in the period of 15 years. Mortality of patients with haemophilia was 13% higher when compared with the general male population (SMR 1.13, 95% CI: 1.01-1.16). Haemorrhage was the main cause of death (n = 254; 32.4%) of which 137 (54%) was intracranial haemorrhage. The total number of deaths due to HIV decreased over the years, and an increase in deaths due to cancer and cardiovascular disease was observed. A total of 129 deaths (16.5%) were related to hepatitis infection, of whom, 109 (86.5%) patients also presented with cirrhosis and hepatocellular carcinoma or other liver diseases. CONCLUSION Mortality rate of Brazilian patients with haemophilia decreased over the evaluated period. Intracranial haemorrhage is still an important cause of death in these patients, which requires major effort for prevention. Death due to age-related cardiovascular disease and cancer has increased over the years, following the same tendency observed in developed countries.

Abstract
The optimal mode of delivery for a pregnant hemophilia carrier is still a matter of debate. The aim of the study was to determine the incidence of intracranial hemorrhage and other major bleeds in neonates with moderate and severe hemophilia in relationship to mode of delivery and known family history. A total of 926 neonates, 786 with severe and 140 with moderate hemophilia were included in this PedNet multicenter study. Vaginal delivery was performed in 68.3% (n=633) and Cesarean section in 31.6% (n=293). Twenty intracranial hemorrhages (2.2%) and 44 other major bleeds (4.8%) occurred. Intracranial hemorrhages occurred in 2.4% of neonates following vaginal delivery compared to 1.7% after Cesarean section (P=not significant); other major bleeds occurred in 4.2% born by vaginal delivery and in 5.8% after Cesarean section (P=not significant). Further analysis of subgroups (n=813) identified vaginal delivery with instruments being a significant risk factor for both intracranial hemorrhages and major bleeds (Relative Risk: 4.78-7.39; P<0.01); no other significant differences were found between vaginal delivery without instruments, Cesarean section prior to and during labor. There was no significant difference in frequency for intracranial hemorrhages and major bleeds between a planned Cesarean section and a planned vaginal delivery. Children with a family history of hemophilia (n=466) were more likely to be born by Cesarean section (35.8% vs. 27.6%), but no difference in the rate of intracranial hemorrhages or major bleeds was found. In summary, vaginal delivery and Cesarean section carry similar risks of intracranial hemorrhages and major bleeds. The ‘PedNet Registry’ is registered at clinicaltrials.gov identifier: 02979119.

Abstract
INTRODUCTION Haemophilia is one of the most common inherited bleeding disorders in the Emergency Department (ED). The most dangerous site of bleeding is the central nervous system. AIMS To describe the characteristics of haemophiliacs arrived to our ED following a head trauma and to analyse the incidence of intracranial haemorrhage (ICH). MATERIALS AND METHODS Retrospective, analytical, observational study, conducted in a Paediatric ED. We included haemophilic patients aged from birth to 16 years who consulted after a head trauma over a 6-year period. Data collected included age, type of haemophilia and head trauma, symptoms, prophylaxis status, CT imaging, treatment and number of visits to the ED. RESULTS About 46 males and 85 episodes were analysed. The median age was 2.38 years. Severe haemophilia A was the most frequent type of disease (50%). All head injuries were mild, and the most frequent mechanism was a collision with an object (38.8%). In 62 episodes (72.9%) the patients were asymptomatic. The rest 23 events had symptomatology, being the most common headache (26%), emesis (21.7%) and drowsiness (17.4%). Head CT was obtained in 31 episodes, founding altered results in 10 (6 of them corresponding to ICH). All the patients with ICH had symptomatology. About 37 episodes required admission. CONCLUSION Intracranial haemorrhage is one of the most dangerous events in haemophiliacs and it may occur after a head trauma. Our study suggests that, in case of head trauma, CT must be obtained in symptomatic patients and in those with additional risk factors. Asymptomatic patients must have prolonged observation.

Abstract
INTRODUCTION Intracranial haemorrhage in children with inherited bleeding disorders is a potentially life-threatening complication and presents a significant therapeutic challenge. AIM To define the characteristics, management and outcomes of intracranial haemorrhage presenting in UK children ≤16 years of age with inherited bleeding disorders from 2003 to 2015. METHOD Retrospective analysis of children treated at UK haemophilia centres. RESULTS Of 66 children presenting with Intracranial haemorrhage (ICH), 82% had haemophilia A or B, 3% VWD and 15% a rare IBD. The IBD was a severe phenotype in 91%. The rates of ICH were 6.4 and 4.2 per 1000 patient years for haemophilia A and B, respectively. Median age at presentation was 4 months (33% neonates; 91% children <2 years of age). In neonates, delivery was spontaneous vaginal (SV) in 11, instrumental in 6, caesarean in 4 and unknown in 1. In children with haemophilia, the risk of ICH after instrumental delivery was 10.6 times greater than after SV delivery. Trauma was more common in children >2 years (67%) than in children 1 month to 2 years (18%; P = .027). Prior to ICH, only 4.5% of children were on prophylaxis. 6% of haemophiliacs had an inhibitor. The median duration of initial replacement therapy was 15 days. Mortality was 13.5%. Neurological sequelae occurred in 39% of survivors, being more common following intracerebral bleeding. In haemophilia survivors, 52% subsequently developed a FVIII inhibitor. CONCLUSION Intracranial haemorrhage occurs most frequently in children with severe IBDs, during the first 2 years of life and in children not receiving prophylaxis. Intracranial haemorrhage often occurs without documented trauma.

Prevalence of Hypertension (HTN) and Cardiovascular Risk Factors in a Hospitalized Pediatric Hemophilia Population. J Pediatr Hematol Oncol 2018; 40:196-199.

Abstract
Improved life expectancy in hemophilia has led to a greater interest in age-related disorders. Hypertension (HTN) as well as cardiovascular disease have been increasingly reported in hemophilic adults but there is currently very limited data in the pediatric population. We conducted a cross-sectional study using data from the 2012 National Health Cost and Utilization Project database to determine the prevalence of HTN and associated cardiovascular risk factors in a hospitalized pediatric hemophilia population, between the ages of 0 to 21 years, in comparison with the general pediatric population. The prevalence of HTN was significantly higher in children with hemophilia (CWH) in comparison with the general pediatric population (1.71% vs. 1.02%, P-value=0.005). When adjusting the analysis for sex, the prevalence of HTN in the hemophilia cohort remained higher, although not statistically significant (1.52% vs. 1.22%, P-value=0.2568). When examining the concomitant presence of ≥1 cardiovascular risk factors in the hypertensive subgroups, CWH had a higher prevalence of obesity (2.64% vs. 1.32%, P-value <0.0001). Interestingly, diabetes mellitus was more prevalent in nonhemophilic children (1.47% vs. 0.56%, P-value=0.0015). These data suggest that cardiovascular risk factors need to be closely monitored in CWH, and a better preventive strategy is likely needed to identify those hemophilic patients at higher risk of developing cardiovascular disease in adulthood.

Abstract
INTRODUCTION Patients with haemophilia are prone to medical emergencies. Emergency departments (ED) often do not have a haematologist on-call for consultation. AIM The aim of this study was to determine the utilization of ED by patients with haemophilia. METHODS Retrospective review of the 'National ED Database Sample' for years 2006-2013 was performed. Patient and hospital demographics were collected. Hospital charges were projected to national levels using discharge-weighted variables. RESULTS During the 8-year study period, haemophilia patients made 162 982 ED visits. This represents 0.016% of total ED visits nationwide. Children utilized ED the most. More than half of patients resided in metropolitan cities; 20% had over $63 000 annual household income. Government insurances were the largest primary payers; 30% had private insurance. In the year 2012, 4488 ED visits with 21 000 diagnoses codes were recorded. Mean age was 29 years. Cardiovascular were the most frequently reported complaints followed by injuries, haemorrhages and sepsis. Seventy percent patients were treated and released from the ED. Two patients died in ED, whereas 35 after admission to hospital. Cause of death included Sepsis (n = 26) and brain haemorrhage (n = 4). Among children, injuries were the most frequent complaints followed by joint/soft tissue disorders; fevers and central line complications. Average charge per visit at private vs. public hospital was $2988 and $2254 respectively (P = 0.03). National estimate of total charges was $60 million. CONCLUSION Patients with haemophilia have tendency to utilize ED. Hypertension was the single most common presenting complaint in adults. No deaths were reported in children from brain haemorrhage.

Abstract
INTRODUCTION Rehabilitation plays an important role in the physical health of patients with hemophilia. However, comprehensive information regarding the utilization of rehabilitation for such patients remains scarce. AIM This population-based study aimed to examine the characteristics, trends, and most important factors affecting rehabilitation usage in patients with hemophilia A using a nationwide database in Taiwan. METHODS Data from 777 patients with hemophilia A who were registered in the National Health Insurance Research Database between 1998 and 2008 were analyzed using SAS 9.0. RESULTS Musculoskeletal or nervous system-related surgical procedures and clotting factor VIII concentrate costs were identified as factors affecting rehabilitation usage; musculoskeletal or nervous system-related surgical procedures (odds ratio = 3.788; P < 0.001) were the most important predictor of whether a patient with hemophilia A would use rehabilitation services. Joint disorders, arthropathies, bone and cartilage disorders, intracranial hemorrhage, and brain trauma were common diagnoses during rehabilitation use. The costs of physical therapy (physiotherapy) comprised the majority (71.2%) of rehabilitation therapy categories. Increasingly, rehabilitation therapy was performed at physician clinics. The total rehabilitation costs were <0.1% of the total annual medical costs. CONCLUSION Musculoskeletal or nervous system-related surgical procedures and increased use of clotting factor VIII concentrate affect the rehabilitation utilization of patients with hemophilia A the most. The findings in this study could help clinicians comprehensively understand the rehabilitation utilization of patients with hemophilia A.
