RESUMO

OBJECTIVE: Traumatic meniscal injuries can cause acute pain, hemarthrosis (bleeding into the joint), joint immobility, and post-traumatic osteoarthritis (PTOA). However, the exact mechanism(s) by which PTOA develops following meniscal injuries is unknown. Since meniscus tears commonly coincide with hemarthrosis, investigating the direct effects of blood and its constituents on meniscus tissue is warranted. The goal of this study was to determine the direct effects of blood and blood components on meniscus tissue catabolism. METHODS: Porcine meniscus explants or primary meniscus cells were exposed to whole blood or various fractions of blood for 3 days to simulate blood exposure following injury. Explants were then washed and cultured for an additional 3 days prior to collection for biochemical analyses. RESULTS: Whole blood increased matrix metalloproteinase (MMP) activity. Fractionation experiments revealed blood-derived red blood cells did not affect meniscus catabolism. Conversely, viable mononuclear leukocytes induced MMP activity, nitric oxide (NO) production, and loss of tissue sulfated glycosaminoglycan (sGAG) content, suggesting that these cells are mediating meniscus catabolism. CONCLUSIONS: These findings highlight the potential challenges of meniscus healing in the presence of hemarthrosis and the need for further research to elucidate the in vivo effects of blood and blood-derived mononuclear leukocytes due to both hemarthrosis and blood-derived therapeutics.

RESUMO

Hemophilia A and B are rare X-linked genetic bleeding disorders due to a complete or partial deficiency in the coagulation factors VIII or IX, respectively. The main treatment for hemophilia is prophylactic and based on coagulation factor replacement therapies. These treatments have significantly reduced bleeding and improved the patients' quality of life. Nevertheless, repeated joint bleedings (hemarthroses), even subclinical hemarthroses, can lead to hemophilic arthropathy (HA). This disabling condition is characterized by chronic pain due to synovial inflammation, cartilage and bone destruction requiring ultimately joint replacement. HA resembles to rheumatoid arthritis because of synovitis but HA is considered as having similarities with osteoarthritis as illustrated by the migration of immune cells, production of inflammatory cytokines, synovial hypertrophy and cartilage damage. Various drugs have been evaluated for the management of HA with limited success. The objective of the review is to discuss new therapeutic approaches with a special focus on the studies that have investigated the potential of using mesenchymal stromal cells (MSCs) in the management of HA. A systematic review of the literature has been made. Most of the studies have focused on the interest of MSCs for the delivery of missing factors VIII or IX but in some studies, more insight on the effect of MSC injection on synovial inflammation or cartilage structure were provided and put in perspective for possible clinical applications.

RESUMO

Various diseases and conditions cause joint disorders. Osteoarthritis (OA) is characterized by the degeneration of articular cartilage, synovitis, and anabolic changes in surrounding bone tissues. In contrast, rheumatoid arthritis (RA) and hemophilic arthropathy (HA) display marked destruction of bone tissues caused by synovitis. RA is a representative autoimmune disease. The primary tissue of RA pathogenesis is the synovial membrane and involves various immune cells that produce catabolic cytokines and enzymes. Hemophilia is a genetic disorder caused by a deficiency in blood clotting factors. Recurrent intra-articular bleeding leads to chronic synovitis through excessive iron deposition and results in the destruction of affected joints. Although the triggers for these two joint diseases are completely different, many cytokines and enzymes are common in the pathogenesis of both RA and HA. This review focuses on the similarities between joint and bone destruction in RA and HA. The insights may be useful in developing better treatments for hemophilia patients with arthropathy and osteoporosis by leveraging advanced therapeutics for RA.

RESUMO

Crohn's disease (CD) is an inflammatory bowel disease affecting the digestive tract, the incidence of which is on the rise worldwide. The most common clinical manifestation of hemophilia is arthropathy secondary to recurrent joint effusions and chronic synovitis. This article reports on a rare 25-year-old male patient with both hemophilic arthropathy and Crohn's disease who was at risk for pathogenic gastrointestinal bleeding. After undergoing endoscopic pathologic testing and genetic testing, a multidisciplinary expert work-up of a treatment and nutritional plan was performed. The patient improved clinically and adhered to conservative treatment. This case report is the first report of this rare co-morbidity, demonstrating the highly pathogenic mutation locus and summarizing the clinical experience of early diagnosis and treatment.

RESUMO

OBJECTIVE: The detrimental effects of blood exposure on articular tissues are well characterized, but the individual contributions of specific whole blood components are yet to be fully elucidated. Better understanding of mechanisms that drive cell and tissue damage in hemophilic arthropathy will inform novel therapeutic strategies. The studies here aimed to identify the specific contributions of intact and lysed red blood cells (RBCs) on cartilage and the therapeutic potential of Ferrostatin-1 in the context of lipid changes, oxidative stress, and ferroptosis. METHODS: Changes to biochemical and mechanical properties following intact RBC treatment were assessed in human chondrocyte-based tissue-engineered cartilage constructs and validated against human cartilage explants. Chondrocyte monolayers were assayed for changes to intracellular lipid profiles and the presence of oxidative and ferroptotic mechanisms. RESULTS: Markers of tissue breakdown were observed in cartilage constructs without parallel losses in DNA (control: 786.3 (102.2) ng/mg; RBCINT: 751 (126.4) ng/mg; P = 0.6279), implicating nonlethal chondrocyte responses to intact RBCs. Dose-dependent loss of viability in response to intact and lysed RBCs was observed in chondrocyte monolayers, with greater toxicity observed with lysates. Intact RBCs induced changes to chondrocyte lipid profiles, upregulating highly oxidizable fatty acids (e.g., FA 18:2) and matrix disrupting ceramides. RBC lysates induced cell death via oxidative mechanisms that resemble ferroptosis. CONCLUSIONS: Intact RBCs induce intracellular phenotypic changes to chondrocytes that increase vulnerability to tissue damage while lysed RBCs have a more direct influence on chondrocyte death by mechanisms that are representative of ferroptosis.

RESUMO

OBJECTIVES: We aimed to discuss the correlation between the Hemophilia Early Detection Ultrasound in China (HEAD-US-C) score and the Hemophilia Joint Health Score version 2.1 (HJHS 2.1) of the knee joint in patients with hemophilia. METHODS: We included 70 male patients with hemophilia admitted to The Second Hospital of Shanxi Medical University; the patients' bilateral knee joints were evaluated using the HEAD-US-C score and HJHS. We analyzed factors influencing hemophilia arthropathy of the knee and examined the correlation between the HEAD-US-C score and HJHS. RESULTS: The joint injury severity was positively correlated with age and the number of bleeds (P < .001). Further, the HEAD-US-C score and HJHS differed according to the severity (both P < .001), but not type (P = .163 and P = .283, respectively), of hemophilia. There was a significant correlation between the HEAD-US-C score and HJHS (P < .001). CONCLUSIONS: Overall, all joint lesions observed on ultrasound corresponded to clinical joint functional abnormalities. Therefore, the HEAD-US-C is important for hemophilic arthropathy evaluation and is useful in explaining abnormal joint function.

RESUMO

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

RESUMO

A goal of the International Prophylaxis Study Group (IPSG) is to provide an accurate instrument to measure MRI-based disease severity of haemophilic arthropathy at various time points, so that longitudinal changes in disease severity can be identified to support decisions on treatment management. We review and discuss in this paper the evaluative purpose of the IPSG MRI scale in relation to its development and validation processes so far. We also critically appraise the validity, reliability and responsiveness of using the IPSG MRI scale in different clinical and research settings, and whenever applicable, compare these clinimetric properties of the IPSG MRI scale with those of its precursors, the compatible additive and progressive MRI scales.

RESUMO

The aim of our narrative review of the literature is to identify the role of six important biomarkers: synovial fluid thrombomodulin, fibroblast-like synoviocytes, synovial tissue growth factor , vascular endothelial growth factor in synovium and peripheral blood, urinary C-terminal telopeptide of type II collagen, and synovial fluid tumor necrosis factor alpha. These urinary, serum and synovial biomarkers illustrated should be evaluated in patients with hemophilic arthropathy for early diagnosis of hemophilic arthropathy, because they have important implications in the development of arthrofibrosis, altered inflammatory response and bleeding. Moreover, better knowledge of their biological activity is important to identify possible new biological treatment options.

RESUMO

BAY 81-8973 is an unmodified, full-length third generation recombinant factor VIII (rFVIII) which offers a more favorable pharmacokinetic (PK) profile, compared to its predecessor sucrose-formulated rFVIII (rFVIII-FS). We here report on a retrospective case series of nine patients affected by hemophilia A (HA), with variable disease severity, bleeding phenotype and comorbidities, to underline our clinical practice on prophylaxis with a recently introduced standard hall-life recombinant Factor VIII. The current case series highlights how the current clinical management of hemophilia is able to personalize treatment in several specific conditions like concomitant illnesses with thrombotic risk and allergic reactions.

RESUMO

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

RESUMO

INTRODUCTION: Haemophilic ankle arthropathy is caused by recurrent spontaneous joint haemorrhaging and leads to pain, deformity and loss of function. In the presence of advanced articular deterioration, therapeutic options are confined to either arthroplasty or arthrodesis, the latter still being referred to as the procedure of choice. However, total ankle replacement (TAR) has recently gained acceptance as an alternative. AIM: To investigate the mid- to long-term results of TAR in haemophilic ankle arthropathy. MATERIALS AND METHODS: Seventeen TARs in 14 male patients (mean age: 43 years [range, 27.4-57.6]), implanted between 1998 and 2012, were retrospectively analysed. Implant survival was estimated using Kaplan-Meier analysis. Haemophilic/viral status, complications and revision surgeries were recorded. Follow-up assessment of 12 TARs was performed 9.6 years (range, 3.3-17.8) postoperatively, including clinical examination, pain and satisfaction scales, the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, and the SF-36. Radiographic evaluation of pre- and follow-up radiographs was conducted. RESULTS: Estimated implant survival was 94% at 5, 85% at 10 and 70% at 15 years, respectively. Three cases required revision surgery. At follow-up, 9.6 years (range, 3.3-17.8) postoperatively, the level of satisfaction was 76% (range, 50-100) and of pain 2/10 (range, 0-6) on the VAS. Range of motion had increased significantly (P = .037). The SF-36 summary scores were comparable to those of a matched standard population. The AOFAS hindfoot score averaged 81 points (range, 73-90). All radiographs revealed component loosening or periprosthetic radiolucency. CONCLUSION: Total ankle replacement in the presence of advanced haemophilic arthropathy is a viable treatment option with favourable mid-/long-term results, maintaining mobility of the ankle joint.

RESUMO

BACKGROUND: Outcomes of total knee replacement in cases of hemophilic patients are worse than in patients who undergo operations due to osteoarthritis. Previous publications have reported varying rates of complications in hemophilic patients, such as infection and an unsatisfactory range of motion, which have influenced the survival of prostheses. Our retrospective study evaluated the data of hemophilic patients regarding changes in the development of the range of motion. METHODS: The data and clinical outcomes of 72 total knee replacements in 45 patients with hemophilia types A and B were reviewed retrospectively. Patients were operated between 1998 and 2013. All of the patients were systematically followed up to record the range of motion and other parameters before and after surgery. RESULTS: The mean preoperative flexion contracture was 17° ± 11° (range, 0°-40°), and it was 7° ± 12° (range, 0°-60°) postoperatively. The mean flexion of the knee was 73° ± 30° (range, 5°-135°) before the operation and 80° ± 19° (range, 30°-110°) at the last follow-up. The mean range of motion was 56° ± 34° (range, 0°-130°) before the operation and 73° ± 24° (range, 10°-110°) at the last follow-up. CONCLUSIONS: Statistical analysis suggested that the range of motion could be improved until the 9th postoperative week. The patient should be operated on until the flexion contracture reaches 22° to obtain a contracture < 15° postoperatively or until the contracture reaches 12° to obtain less than 5°. The operation generally does not change the flexion of the knee in cases of hemophilic patients, but it reduces the flexion contracture and therefore improves the range.

RESUMO

BACKGROUND: The main clinical manifestations of hemophilia are muscle and joint bleeding. Recurrent bleeding leads to a degenerative process known as hemophilic arthropathy. The development of inhibitors (antibodies against FVIII/FIX concentrates) is the main complication in the treatment of hemophilia. The objective was to assess the safety and efficacy of manual therapy treatment in a patient with hemophilia and inhibitor. CASE PRESENTATION: A 26-year-old patient with hemophilia B and inhibitor received physiotherapy treatment based on manual therapy for 3 months, with a frequency of 2 sessions per week. The joint status was evaluated using the Hemophilia Joint Health Score; pain was assessed with the Visual Analog Scale; and the range of movement was evaluated using a universal goniometer. The patient developed no joint bleeding in the knees or ankles as a result of the physiotherapy treatment. Following treatment, improvements were noted in the range of movement of knees and ankles, the perception of pain in both knees, and ankle functionality. CONCLUSIONS: Until now, manual therapy using joint traction was contraindicated in patients with hemophilia and inhibitor, as it was feared to cause possible joint bleeding. This is the first case study to address the safety and efficacy of manual therapy in a patient with hemophilia and an inhibitor. The results of this study may help to establish which manual therapy treatments are indicated in patients with hemophilic arthropathy and inhibitors. Thus, a physiotherapy program based on manual therapy may be safe in patients with hemophilia and inhibitor and such therapy may improve joint condition, pain, and joint range of motion in patients with hemophilia and inhibitor. Randomized clinical trials are needed to confirm the results of this case study.

RESUMO

HYPOTHESIS: It was hypothesized that the long-term survivorship and clinical outcome are reasonable, justifying total elbow arthroplasty (TEA) in patients with end-stage hemophilic arthropathy. METHODS: From 2002 to 2012, 13 primary TEAs (Coonrad-Morrey design) were implanted in 9 consecutive patients with an average age of 55 (range, 39-76) years. Type A hemophilia was diagnosed in 7 patients and type B hemophilia in 2 patients. Clinical and radiographic results of all (11 TEAs) but 1 patient were retrospectively analyzed. RESULTS: After a mean of 9.1 (range, 5-14) years, the mean visual analog scale score for pain, total Mayo Elbow Performance Score, and subjective elbow value were significantly improved from 5 (standard deviation, ±3) to 2 (±2; P = .007) points, from 64 (±16) to 89 (±11; P = .008) points, and from 47% (±15%) to 81% (±11%; P < .001), respectively. Whereas the flexion arc remained unchanged (P = .279), mean active pronation improved significantly (P = .024). Postoperative complications were recorded in 8 TEAs (62%), whereas 5 TEAs (38%) underwent partial component exchange after a mean of 7.2 (range, 3-10) years: 2 for periprosthetic infection, 2 for polyethylene wear, and 1 for humeral component loosening. Of the living patients after partial component exchange (n = 3), the mean final total Mayo Elbow Performance Score, flexion and rotation arc, visual analog scale score for pain, and subjective elbow value were comparable with the results of the living patients without revision surgery (n = 8). CONCLUSIONS: TEA for patients with advanced hemophilic arthropathy is associated with a substantial complication and revision rate. However, even after revision without implant removal, it provides good functional and subjective long-term results.

RESUMO

PURPOSE: Increased articular 99mTc MDP uptake on blood pool imaging (BPI) of patients with rheumatologic conditions is indicative of active inflammatory changes, and has been suggested as a strong predictor of response to radiosynoviorthesis (RSO). In this study, we aimed to assess the value of pretreatment BPI positivity (i.e. scintigraphic-apparent hyperemia) for successful RSO in hemophilic arthropathy. METHODS: Thirty-four male patients with painful hemophilic arthropathy underwent RSO after failure of conservative treatment. Treated joints comprised the knee in eight, elbow in five, and ankle in 21 patients. Pretreatment triple-phase bone scintigraphy showed hyperemic joints (pathologic BPI) in 17 patients, whereas 17 patients had no increased tracer uptake on BPI. Response to RSO was evaluated 6 months post-treatment by measuring changes in intensity of arthralgia according to the visual analog scale (VAS), bleeding frequency, and range of motion. The association between hyperemia (pathologic BPI) and treatment outcome was examined using nonparametric tests for independent samples. RESULTS: Clinically evident pain relief occurred in 26 patients (76.5 %), and the mean VAS decreased from 7.7 ± 1.1 to 4.6 ± 2.7 (p < 0.001). Joint bleeding frequency (hemarthrosis) decreased from 4.5 ± 0.6 to 2.1 ± 0.4 during the first 6 months after RSO (p < 0.001). For both parameters (pain relief and bleeding frequency), patients experienced a similar benefit from RSO regardless of pretreatment BPI: arthralgia (p = 0.312) and frequency of hemarthrosis (p = 0.396). No significant improvement was observed for range of motion, but it was significantly more restricted in hyperemic joints both before (p = 0.036) and after treatment (p = 0.022). CONCLUSIONS: Hemophilic arthropathy can be effectively treated with RSO regardless of pre-therapeutic BPI. Patients in whom articular hyperemia is not detectable by scintigraphy may have similar (outstanding) outcomes, and thus should not be excluded from treatment.

RESUMO

Hemophilia is a congenital clotting factor deficiency characterized by spontaneous and trauma-related bleeding. Spontaneous bleeding shows a predilection for joints, and repeated hemarthroses lead to a disabling condition called hemophilic arthropathy. Treatment of this condition consists of preventing joint bleeding on the one hand and orthopedic surgery as a last resort on the other. Up till now, there is no disease modifying therapy available to fill the gap between these extremes. This review provides an overview of the pathogenesis of hemophilic arthropathy in order to identify potential targets for therapy. Joint bleeding induces synovial inflammation, cartilage degeneration and bone damage. These processes interact with each other and result in a vicious circle. Hemarthrosis promotes synovial hypertrophy and neoangiogenesis, increasing the susceptibility to mechanical damage and subsequent bleeding. The inflamed synovium affects the cartilage, while cartilage is also directly affected by blood via the release of cytokines and metalloproteinases, and via hydroxyl radical formation inducing chondrocyte apoptosis. Apart from the inflammatory pathways, iron plays a pivotal role in this process, as does the fibrinolytic system. Considering its pathogenesis, potential targets for disease modifying therapy in hemophilic arthropathy are iron, inflammation, vascular remodeling, hyperfibrinolysis, bone remodeling and cartilage regeneration. So far, iron chelators, anti-inflammatory therapy, anti-fibrinolytics and bone remodeling agents have demonstrated beneficial effects, predominantly in a preclinical setting. There is still a long way to go before these interventions will translate into clinical practice. The most important challenges are: establishing a universal outcome measure to predict efficacy in humans, and determination of the optimal route and timing to administer disease modifying therapy.

RESUMO

Hemophilia is an X-linked recessive deficiency of clotting factor VIII (hemophilia A) or IX (hemophilia B) that can result in hemarthrosis of various joints, including the elbow. Left unchecked, this can lead to progressive joint destruction and significant morbidity. Appropriate management of the elbow joint through prophylactic measures, accurate imaging, and timely intervention is essential. Replacing or supplementing deficient factor with a plasma-derived or recombinant factor concentrate can minimize bleeding episodes. Joints should be routinely monitored for damage. Plain films offer an inexpensive window into bone disease and joint space changes but lack soft tissue detail and may not detect early changes. Magnetic resonance imaging provides a high level of detail but may be limited by its cost and need for sedation in younger patients. Ultrasound may not achieve the same level of resolution as magnetic resonance imaging, but it is increasingly used as a convenient, effective, and relatively inexpensive alternative. Patients who experience hemarthrosis of the elbow with joint damage often require more invasive treatment. Radiosynovectomy and arthroscopic synovectomy are effective at minimizing pain and preventing future bleeding episodes, whereas extensive joint damage may necessitate total elbow replacement.

RESUMO

The clinical histories of 45 consecutively performed TKAs in 32 patients with hereditary bleeding disorders were reviewed retrospectively. The mean follow up was 88.7 (range, 24-232) months. The cumulative probability of infection free-survival was 87.8% after 180 months. When removal of component was defined as endpoint, the survival probability was 86.4% after 180 months. In regression analysis no significant independent risk factors for infection or aseptic loosening were identified. The HSS score improved significantly from 45 to 85 points. Hemophilic patients can be considered to be at high risk for prosthetic failure, our study has demonstrated favorable functional results of total knee arthroplasty in hemophilic patients.

RESUMO

Hemophilic arthropathy (HA) is a condition caused by recurrent intra-articular bleeding in patients with hemophilia. Pro-inflammatory cytokines play a crucial role in the pathogenesis of HA. Our previous research demonstrated that a novel compound, piperazino-enaminone (JODI), effectively inhibited pro-inflammatory cytokines, including IL-6, MCP-1, MIP-1α, and MIP-1ß, in a mouse model of hemarthrosis. This study aims to enhance the anti-inflammatory effect of JODI by employing nanoparticle delivery systems, which could potentially improve its poor water solubility. Here, we developed liposomes modified with polyethylene glycol (PEG) for the delivery of JODI (JODI-LIP), and found that JODI-LIP exhibited uniform size, morphology, good stability and in vitro release degree. JODI-LIP mitigated cytotoxicity of JODI, and significantly suppressed the production of pro-inflammatory cytokines (TNF-α and IL-1ß) and nitric oxide (NO) release in RAW 264.7 cells stimulated by lipopolysaccharide (LPS), as well as the proliferation of human fibroblast-like synovial (HFLS) cells. In a murine model of HA, JODI-LIP demonstrated superior efficacy in ameliorating joint swelling and synovitis, compared to JODI. Importantly, JODI-LIP markedly reduced pro-inflammatory cytokines (TNF-α, IFN-γ, IL-33, and MCP-1) in injured joints. No hepatic or hematological toxicity was observed in mice treated with JODI-LIP. In summary, our results suggest that JODI-LIP holds promise as a therapeutic intervention for HA by attenuating pro-inflammatory cytokine levels.
