TL;DR: This meta-analysis confirms the association between severe haemophilia and low BMD and future studies should investigate fracture rates and interventions to prevent bone loss in persons with haemophile.
Abstract: Osteoporosis is caused by bone mineral density (BMD) reduction. Haemophilia patients are at increased risk of osteoporosis because of decreased physical activity and blood-borne virus infections. This systematic review of the literature aims at evaluating BMD reduction in severe haemophilia patients and its correlation with patients’ characteristics. Seven case-control studies evaluating lumbar BMD values [g/cm2] (all studies), BMI (5/7 studies), and hepatitis C virus (HCV) seropositivity (6/7 studies) in severe haemophilia patients and controls were meta-analysed. Standardised mean difference (SMD) of BMD was used to compare cases and controls. The effect of body mass index (BMI) and HCV infection was investigated by meta-regression. One hundred one adult cases (age 33 ± 8.9) with 101 controls and 111 paediatric cases (age 8 ± 3.6) with 307 controls were available for analysis. Lumbar BMD was significantly lower in severe haemophilia patients than in controls, both in adult (pooled SMD –1.379, 95% confidence interval [CI] –2.355 to –0.403, p=0.006) and children (pooled SMD –0.438, 95% CI –0.686 to –0.189, p=0.001). The reduction in BMD in patients versus controls was not significantly correlated with the reduction in BMI or with the percentage of HCV-infected patients. This meta-analysis confirms the association between severe haemophilia and low BMD. Future studies should investigate fracture rates and interventions to prevent bone loss in persons with haemophilia

TL;DR: These evidence‐based guidelines offer practical recommendations on the diagnosis and general management of hemophilia, as well as the management of complications including musculoskeletal issues, inhibitors, and transfusion‐transmitted infections.
Abstract: Hemophilia is a rare disorder that is complex to diagnose and to manage. These evidence-based guidelines offer practical recommendations on the diagnosis and general management of hemophilia, as well as the management of complications including musculoskeletal issues, inhibitors, and transfusion-transmitted infections. By compiling these guidelines, the World Federation of Hemophilia aims to assist healthcare providers seeking to initiate and/or maintain hemophilia care programs, encourage practice harmonization around the world and, where recommendations lack adequate evidence, stimulate appropriate studies.

TL;DR: It is believed that appropriately modified programmes can potentially allow all PWH to experience the physical and psychosocial benefits of being physically active which may ultimately lead to an improved QoL.
Abstract: Most health care professionals involved in the management of people with haemophilia (PWH) believe that exercise is beneficial and its practice is widely encouraged. This article aims to demonstrate that appropriate exercise (adapted to the special needs of the individual PWH) may be beneficial for all PWH through improved physical, psychosocial and medical status. Based on evidence gathered from the literature, many PWH, particularly those using long-term prophylaxis or exhibiting a mild/moderate bleeding phenotype, are as active as their healthy peers. PWH experience the same benefits of exercise as the general population, being physically healthier than if sedentary and enjoying a higher quality of life (QoL) through social inclusion and higher self-esteem. PWH can also gain physically from increased muscle strength, joint health, balance and flexibility achieved through physiotherapy, physical activity, exercise and sport. Conversely, very little data exist on activity levels of PWH in countries with limited resources. However, regarding specific exercise recommendations in PWH, there is a lack of randomized clinical trials, and consequently formal, evidence-based guidelines have not been produced. Based on published evidence from this review of the literature, together with the clinical experience of the authors, a series of recommendations for the safe participation of PWH in regular physical activities, exercises and sport are now proposed. In summary, we believe that appropriately modified programmes can potentially allow all PWH to experience the physical and psychosocial benefits of being physically active which may ultimately lead to an improved QoL.

TL;DR: Prevention of joint arthropathy needs to focus on prevention of haemarthroses through prophylaxis, identifying early joint disease through the optimal use of cost effective imaging modalities and the validation of serological markers of jointArthropathy.
Abstract: Summary Haemophilia is an inherited disorder of clotting factor deficiencies resulting in musculoskeletal bleeding, including haemarthroses, leading to orthopaedic complications. The pathogenesis of haemophilic joint arthropathy continues to be explored and there is evidence to suggest that iron, cytokines, and neo angiogenesis can initiate synovial and early cartilage damage resulting in molecular changes and the perpetuation of a chronic inflammatory state. This joint arthropathy has long term consequences for bone health resulting in chronic pain and quality of life issues in the individual with haemophilia. Haemarthroses can be prevented by the administration of clotting factor concentrates (prophylaxis). However, high costs and the need for venous access devices in younger children continue to complicate recommendations for universal prophylaxis. In patients who fail or refuse prophylaxis, procedures, such as synovectomy and arthroplasty, can provide relief from repeated haemarthroses. The optimal timing of these, however, is not well defined. Prevention of joint arthropathy needs to focus on prevention of haemarthroses through prophylaxis, identifying early joint disease through the optimal use of cost effective imaging modalities and the validation of serological markers of joint arthropathy. Screening for effects on bone health and optimal management of pain to improve quality of life are, likewise, important issues.

TL;DR: This systematic review of the available evidence on the safety and effectiveness of exercise for people with haemophilia found that all but one of the outcomes assessed were rated as low or very low due to the small sample sizes and potential bias.
Abstract: Background Haemophilia is a bleeding disorder associated with haemorrhaging into joints and muscles. Exercise is often used to aid recovery after bleeds, and to improve joint function in the presence of arthropathy. Objectives Our objective was to systematically review the available evidence on the safety and effectiveness of exercise for people with haemophilia. Search methods We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register and electronic databases PubMed, OVID-Embase, and CINAHL. We hand searched abstracts from congresses of the World Federation of Hemophilia and the European Hematology Association, trial registries and the reference lists of relevant articles. Date of the last search of the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register: 14 December 2016. Selection criteria Randomized or quasi-randomized controlled studies comparing any exercise intervention considered relevant in haemophilia management including supervised, unsupervised, aquatic, strengthening, aerobic or cardiovascular, stretching, proprioceptive and balance training exercise programs in males of any age with haemophilia A or B of any severity (those with co-morbidities were not excluded). Data collection and analysis Two authors reviewed the identified abstracts to determine their eligibility. For studies meeting the inclusion criteria, full articles were obtained. The two authors extracted data and assessed the risk of bias. Any disagreements were resolved by discussion. The authors contacted study investigators to obtain any missing data. Main results Eight studies were included, which represented 233 males with all severities of haemophilia A and B, ranging in age from eight years to 49 years. Study duration ranged from four to 12 weeks. Exercise interventions varied greatly and included resistance exercises, isometric exercises, bicycle ergometry, treadmill walking and hydrotherapy; therefore, comparison between studies was difficult. None of the studies measured or reported adverse effects from the interventions. None of the studies reported outcomes regarding bleed frequency, quality of life or aerobic activity. Overall risk of bias across all studies was assessed as unclear. Very few studies provided sufficient information for comparison. None of the studies reported data that favoured the control group. One study reported that six weeks of resistance training improved joint health status (Colorado score) compared to controls. The addition of pulsed electromagnetic fields also improved ankle scores compared to exercises alone, but this was not seen in the elbows or knees. Two studies reported statistically significant improvements in pain intensity after exercise interventions compared to controls. Hydrotherapy exercises produced significant decreases in pain compared to controls and land-based exercise groups. Two studies found improvement in joint motion in the exercise group compared to controls. One study compared land- and water-based exercises; there was no difference in the range of motion between the two groups; however, the water-based exercise group did show improvement over the control group. One study, comparing joint traction and proprioceptive neuromuscular facilitation for the elbow to a control group, showed no differences in biceps girth or strength after 12 weeks of intervention. Some studies reported comparisons between interventions. In one study, treadmill training significantly improved balance in children compared to bicycle ergometry. Another study added partial weight bearing exercises to quadriceps exercises and showed improved walking tolerance. Four studies evaluated quadriceps or hamstring strength (or both). The addition of bicycle ergometry and exercises with weights was more effective than static exercises and treadmill walking for strengthening knee flexors and extensors. Partial weight-bearing exercises through range were more effective than static and short arc exercises for improving knee extensor strength. The addition of treadmill walking to ultrasound, stretching and strengthening exercises showed increased peak torque of knee flexors and extensors and decrease in knee effusion. The results should be interpreted with caution due to the quality of evidence (GRADE) as outlined in the summary of findings tables, which demonstrates that all but one of the outcomes assessed were rated as low or very low due to the small sample sizes and potential bias. Authors' conclusions These results must be considered with caution. There is a lack of confidence in the results due to the small number of included studies and the inability to pool the results due to the heterogeneity of outcome measures. Most exercise interventions produced improvement in one or more of the measured outcomes including pain, range of motion, strength and walking tolerance. Hydrotherapy may be more effective than land exercises for pain relief in adults. Functional exercises such as treadmill walking and partial weight bearing exercises seem to be more effective than static or short arc exercises for improving muscle strength. These findings are consistent with the many non-controlled intervention reports in the haemophilia literature. No adverse effects were reported as a result of any of the interventions. However, some groups used prophylactic factor prior to exercise and other groups studied only subjects with moderate haemophilia. Therefore, the safety of these techniques for persons with severe haemophilia remains unclear.
