[PMID: 38212803 PMCID: PMC10782745 DOI: 10.1186/s13018-023-04499-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 12/20/2023] [Indexed: 01/13/2024] Open
Abstract
INTRODUCTION Patients with haemophilia (PWH) may have lower bone mineral density (BMD). The risk of low BMD in PWH has not been comprehensively analysed. This study aimed to examine the risk of low BMD and changes in BMD in PWH. METHODS A comprehensive systematic search was performed in 4 databases: PubMed, Embase, Web of Science, and Cochrane Library. The last search was carried out on 11 December 2022. Review Manager 5.4 and Stata 16 were used for meta-analysis. Odds ratios were calculated by the incidence of low BMD between the haemophilia and control groups in each study. A meta-analysis of the odds ratios for each study was performed to estimate pooled odds ratios. Fixed effects models or random effects models were used to assess outcomes. Heterogeneity was evaluated using Higgins' I2. Subgroup analysis and sensitivity analysis were performed to interpret the potential source of heterogeneity. A funnel plot, Egger's regression test, and the trim-and-fill method were used to assess publication bias. RESULTS 19 of 793 studies, published between 2004 and 2022, that were identified by search strategy were included in this meta-analysis. The risk for low BMD was approximately four times higher compared to controls. PWH have significantly lower lumbar spine, femoral neck, and total hip BMD. Subgroup analysis showed that the risk of low BMD did not increase significantly in developed countries. Very low heterogeneity was observed in the meta-analysis of the risk of low BMD. The result from Egger's regression test suggested that there may be publication bias. However, the meta-analysis results did not alter after the trim-and-fill correction and the findings were robust. CONCLUSION Haemophilia was associated with an increased risk of low BMD. However, the risk of low BMD did not increase significantly in developed countries. And BMD was reduced in PWH, regardless of age, region, or economic ability. For PWH, our concerns should extend beyond bleeding and osteoarthritis to encompass BMD starting at a young age.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19116496. [PMID: 35682087 PMCID: PMC9180237 DOI: 10.3390/ijerph19116496] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 05/17/2022] [Accepted: 05/24/2022] [Indexed: 11/16/2022]
Abstract
Background: This study aims to identify factors affecting health-related quality of life (HRQoL) in Chinese patients with hemophilia in Hong Kong, and to examine the association between treatment adherence and HRQoL outcomes. Methods: Patients with hemophilia A or B from a non-governmental organization reported their HRQoL and treatment adherence to prophylactic therapy using validated tools. Univariate tests and multivariable regression analysis were used to compare differences in outcomes across clinically relevant subgroups. Results: Fifty-six patients were recruited (mean age 30.4 [17.4] years; majority hemophilia A: 75%; moderate-to-severe severity: 88%). Patients who received prophylactic treatment reported fewer work/school problems (25.8 [18.9] versus 51.5 [26.3]; p = 0.001) than those who received on-demand therapy. The multivariable model showed that older age (B = 0.42, 95% CI = 0.093−0.75) and living in public housing (B = 10.24, 95% CI = 0.70−19.77) were associated with worse HRQoL. Older age was associated with treatment non-adherence (r = 0.66, p < 0.0001). Patients with poor adherence tended to report worse functioning in sports/leisure (r = 0.31, p = 0.033). Conclusions: Our results suggest that patients who were older, had lower education attainment and received on-demand treatment had poorer perception of their health. Improving adherence may lead to better HRQoL. Future work includes evaluating the occupational needs prospectively in this population.

Sun J, Zhou X, Hu N. Factor VIII replacement prophylaxis in patients with hemophilia A transitioning to adults: a systematic literature review. Orphanet J Rare Dis 2021; 16:287. [PMID: 34174912 PMCID: PMC8236177 DOI: 10.1186/s13023-021-01919-w] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Accepted: 06/13/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Despite the advantages of prophylactic treatment for hemophilia, patients tend to discontinue or not adhere to it because of several challenges such as long-term use, high cost, young patients transitioning to adolescents, and switch to self-infusion or self-care. The goal of this systematic literature review is to emphasize adherence to and efficiency of prophylactic treatment in adults. METHODS A literature review was conducted in PubMed, Embase, and Cochrane databases until April 2021 according to PRISMA guidelines, and the protocol was registered with PROSPERO (CRD42020220085). Studies evaluating the efficacy of prophylaxis in enhancing the quality of life were included. RESULTS A total of 31 articles involving 2379 patients with hemophilia were included in this systematic review. Of these, 26 studies were observational, questionnaire-based studies, and 5 were randomized controlled trials. The majority of studies reported lower annualized bleeding rates in patients receiving prophylaxis compared with those receiving on-demand treatment or those who discontinued prophylaxis. Standard-dose prophylaxis was reported to be effective in most of the studies. In developing countries like China, data suggest that low doses were administered because of limited available resources. However, standard dose or individualized prophylaxis should be provided to prevent joint damage in the long term. Compared with adults, greater adherence to treatment was observed in patients aged < 16 years. CONCLUSION This systematic review emphasizes the importance of adherence to prophylaxis among young adults transitioning from childhood. In countries like China, low-dose prophylaxis can help in preventing joint bleeds in the short term, but in the long term, standard-dose therapy has shown high adherence among young adults and better joint health, in turn improving the quality of life.

NAN FANG YI KE DA XUE XUE BAO = JOURNAL OF SOUTHERN MEDICAL UNIVERSITY 2021; 41:536-542. [PMID: 33963712 PMCID: PMC8110454 DOI: 10.12122/j.issn.1673-4254.2021.04.08] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To explore the clinical phenotype and changes in joint structure and function in adolescent patients with severe hemophilia A under different doses of FVIII. OBJECTIVE Forty- three adolescents with severe hemophilia A aged 4-18 years were divided into on-demand group (n=7), low-dose group (FVIII dose of 10-15 U/kg, 2-3 times a week, and ≤30 U/kg a week; n=17), and intermediate-dose group (FVIII dose of 15-20 U/kg, 2-3 times a week, and 45-60 U/kg a week (n=19). The 3 groups were compared for their clinical bleeding phenotype, annual bleeding rate (ABR), annual joint bleeding rate (AJBR), annual the most severe joint bleeding rate, joint imaging scores (ultrasound HEAD-US score and IPSG MRI score), Hemophilia Joint Health Score (HJHS) and Functional Independence Score in Hemophilia (FISH) within 24 months. OBJECTIVE Compared with that in on-demand group, the ABR was significantly reduced in the low- and intermediate-dose groups (P=0.004 and 0.000, respectively), and was reduced by 32.87% in the intermediate-dose group as compared with the low-dose group. The AJBR (P < 0.01) and annual the most severe joint bleeding rate (P < 0.05) also differed significantly among the 3 groups. The number of bleeding episodes increased progressively with time in the on-demand group, remained stable in the low- dose group, and tended to decrease in the intermediate-dose group. The imaging scores of the most severe joints showed lesion progression in all the 3 groups. The ultrasound scores, which increased steadily in the on-demand group, showed significantly lowered increment rates in the low- and intermediate-dose groups (P=0.002 and 0.000, respectively). The MRI scores showed also delayed increment in the low- and intermediate-dose groups as compared with the on-demand group (P=0.041 and 0.000, respectively), and the increment was accelerated in the on-demand and low-dose group but remained stable in the intermediate-dose group. The increment of the HJHS scores was significantly higher in the on-demand group than in the lowand intermediate-dose groups (P=0.003 and 0.000, respectively), and the scores increased at a steady rate in the on-demand group but tended to decrease in the latter two groups. The FISH score was decreased by 0.29±3.09 in the on-demand group but was increased significantly in the low- and intermediate-dose groups compared with the on-demand group (P=0.000). OBJECTIVE In Chinese adolescents with severe hemophilia A, low- and intermediate-dose FVIII prophylaxis, especially at the intermediate dose, is better than on- demand treatment for protecting joint structure and function.

Safety and Efficacy of Moroctocog Alfa (AF-CC) in Chinese Patients with Hemophilia A: Results of Two Open-Label Studies. J Blood Med 2020; 11:439-448. [PMID: 33269010 PMCID: PMC7701140 DOI: 10.2147/jbm.s241605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Accepted: 10/15/2020] [Indexed: 11/23/2022] Open
Abstract
Introduction Moroctocog alfa albumin-free cell culture (AF-CC) increases plasma levels of factor VIII (FVIII) activity and, in China, is indicated for the control and prevention of bleeding episodes in patients with hemophilia A. This study aimed to evaluate the efficacy, safety, and recovery data of moroctocog alfa (AF-CC) in patients with hemophilia participating in two open-label studies, both conducted in China. Methods The authorization study (clinicaltrials.gov identifier NCT00868530) enrolled patients aged ≥6 years, previously treated with ≥1 exposure day of FVIII replacement therapy. The real-world study (clinicaltrials.gov identifier NCT02492984) enrolled patients of any age who were previously untreated or requiring surgical prophylaxis. In both studies, on-demand treatment was administered over 6 months. Key assessments included response to treatment, FVIII inhibitor development, and recovery. Results In the authorization study (N = 53; mean age, 23.2 years; severe hemophilia, 23%), response was excellent/good for 90% of infusions at 24 hours. Seven patients developed inhibitors. Mean (SD) FVIII recovery at the initial and final visits was 1.77 (0.50) and 1.67 (0.45) (IU/dL)/(IU/kg), respectively. In the real-world study (N = 85; mean age, 9.5 years; severe hemophilia, 58%), response was rated as excellent or good for most (87%) on-demand infusions and for all surgical prophylaxis patients (n = 14). Seven patients developed FVIII inhibitors. Mean (SD) FVIII recovery at the initial and final visits was 1.71 (0.50) and 1.68 (0.31) (IU/dL)/(IU/kg), respectively. No new safety signals were observed in either study. Conclusion On-demand treatment and surgical prophylaxis with moroctocog alfa (AF-CC) is safe and effective for both previously treated and previously untreated Chinese patients with hemophilia A.
