BACKGROUND: Hemophilia A is a factor VIII deficiency, associated with spontaneous, recurrent bleeding episodes. This may lead to comorbidities such as arthropathy and joint replacement, which contribute to morbidity and increased health care expenditure. Recombinant factor VIII Fc fusion protein (rFVIIIFc), a prolonged half-life factor therapy, requires fewer infusions, resulting in reduced treatment burden. OBJECTIVE: Use a budget impact analysis to assess the potential economic impact of introducing rFVIIIFc to a formulary from the perspective of a private payer in the United States...

: Chikungunya virus (CHIKV) is an arthritogenic alphavirus causing epidemics of acute and chronic arthritic disease. Herein we describe a comprehensive RNA-Seq analysis of feet and lymph nodes at peak viraemia (day 2 post infection), acute arthritis (day 7) and chronic disease (day 30) in the CHIKV adult wild-type mouse model. Genes previously shown to be up-regulated in CHIKV patients were also up-regulated in the mouse model. CHIKV sequence information was also obtained with up to ≈8% of the reads mapping to the viral genome; however, no adaptive viral genome changes were apparent...

OBJECTIVES: Macroscopic studies have suggested a link between distal border synovial invaginations of the navicular bone and the distal interphalangeal joint. However, many practitioners consider that these invaginations are directly and solely related to navicular disease. The objective was to investigate the communication pattern of these synovial invaginations with the synovial compartments of the distal interphalangeal joint and the navicular bursa, using minimally invasive imaging techniques...

BACKGROUND: Alkaptonuria (AKU) is an ultra-rare disease associated to the lack of an enzyme involved in tyrosine catabolism. This deficiency results in the accumulation of homogentisic acid (HGA) in the form of ochronotic pigment in joint cartilage, leading to a severe arthropathy. Secondary amyloidosis has been also unequivocally assessed as a comorbidity of AKU arthropathy. Composition of ochronotic pigment and how it is structurally related to amyloid is still unknown. METHODS: We exploited Synchrotron Radiation Infrared and X-Ray Fluorescence microscopies in combination with conventional bio-assays and analytical tools to characterize chemical composition and morphology of AKU cartilage...

BACKGROUND: Congenital insensitivity to pain with anhidrosis (CIPA) is an extremely rare autosomal recessive autonomic and sensory neuropathy. CIPA is associated with various mutations in NTRK1. CASES: Two unrelated Chinese patients presented separately with symptoms of insensitivity to pain, inability to sweat, repeated painless fractures, and Charcot arthropathy were recruited. Both of them were clinically diagnosed with CIPA. Increased serum bone resorption marker (β-CTX) levels and decreased BMD were observed in both patients...

An acutely painful, erythematous wrist can be due to a variety of pathologic processes, including crystalline arthropathy, infection, trauma, osteoarthritis, and systemic disease. The broad differential diagnosis of the inflamed wrist and nonspecific clinical findings make accurate diagnosis challenging. There is no published clinical or laboratory criterion that reliably differentiates septic wrist arthritis from a sterile inflammatory arthropathy. For septic joint patients, long-term results are notably poorer in patients with a delay in treatment, therefore establishing evidenced-based guidelines deserves attention...

Skeletal dysplasias form a group of skeletal disorders caused by mutations in macromolecules of cartilage and bone. The severity of skeletal dysplasias ranges from precocious arthropathy to perinatal lethality. Although the pathomechanisms of these disorders are generally well defined, the feasibility of repairing established aberrant skeletal tissues that developed in the presence of mutant molecules is currently unknown. Here, we employed a validated mouse model of spondyloepiphyseal dysplasia (SED) that enables temporal control of the production of the R992C (p...

BACKGROUND: Hyperactive secretion and pathogenic effects of interleukin (IL)-17 and IgA have been detected in different arthropathies. Recent evidence has revealed that TH17 cytokines regulate mucosal IgA secretion. However, it is unknown whether and how IL-17 mediates synovial IgA production. Here we aim to investigate the connection of synovial IL-17 with IgA production in the joint. In this study we included synovial fluids (SF) from patients with rheumatoid arthritis (RA; n = 66), spondyloarthritis (SpA; n = 18) and osteoarthritis (OA; n = 36)...

We report a case of a complex limb salvage ankle arthrodesis in a patient with Charcot arthropathy. A step-cut osteotomy was performed in order to tackle the issues of anterior tibial bone loss; worsening leg length discrepancy; soft tissue contraction; joint instability and high risk of non-union. The construct formed by the step-cut allowed for the preservation of good bone stock; avoidance of further limb shortening; increased torsional stability and increased surface area for bony union. This resulted in a patient with a stable, plantigrade foot appropriate for footwear...

Alkaptonuria (AKU) is a rare inherited disease resulting from a deficiency of the enzyme homogentisate 1,2-dioxygenase which leads to the accumulation of homogentisic acid (HGA). AKU is characterised by severe cartilage degeneration, similar to that observed in osteoarthritis. Previous studies suggest that AKU is associated with alterations in cytoskeletal organisation which could modulate primary cilia structure/function. This study investigated whether AKU is associated with changes in chondrocyte primary cilia and associated Hedgehog signalling which mediates cartilage degradation in osteoarthritis...

Spontaneous or traumatic hemorrhages into joints that occur in the course of congenital bleeding disorders due to deficiencies of plasma clotting factors lead to early and extensive damage to joints. Arthropathy in those patients most commonly affects the knee, elbow and ankle. Replacement surgery of the damaged joint is the only effective way to treat such advanced changes. Although arthritis of the elbow is quite common, surgery is rarely undertaken; hence relevant reports in the literature are limited to individual or small groups of cases...

INTRODUCTION: Mild haemophilia is a congenital bleeding disorder affecting males. The burden of arthropathy in mild haemophilia has not been comprehensively described. AIM: The aim of this study was to compare the incidence, age at diagnosis and surgery for arthropathy and related hospitalizations between people with mild haemophilia and the general population in Sweden. METHODS: This was a register-based cohort study. Eligible participants were those with mild haemophilia born between 1941 and 2008 and a randomly selected, birthdate and sex-matched comparison group from the general population...

BACKGROUND: Reverse total shoulder arthroplasty (RTSA) is a viable treatment option for rotator cuff tear arthropathy but carries a complication risk of scapular fracture. We hypothesized that using screws above the central glenoid axis for metaglene fixation creates a stress riser contributing to increased scapula fracture incidence. Clinical type III scapular fracture incidence was determined with screw placement correlation: superior screw vs. screws placed exclusively below the glenoid midpoint...

BACKGROUND: Long-term results regarding tear progression, arthropathy, and clinical scores of unrepaired rotator cuff tears are largely unknown. This study investigated whether the condition of the glenohumeral joint and rotator cuff had deteriorated at a minimum of 20 years after an acromioplasty without cuff repair and assessed the clinical results. METHODS: A retrospective analysis was conducted of a consecutive series of patients treated between 1989 and 1993 with acromioplasty without cuff repair due to subacromial pain and cuff tear...

The treatment of end-stage hemophilic arthropathy of the ankle joint remains a controversial problem, and total ankle replacement (TAR) is considered to be a valuable management option. Physiotherapy continues to be an extremely important part of TAR and has a tremendous impact on the outcomes of this procedure. Given the lack of data on the latter, this study details a protocol of perioperative physiotherapy in TAR in patients with inherited bleeding disorders (IBD). The protocol outlined in this paper was devised via consultations within an interdisciplinary group, the authors' own experiences with TAR in hemophilic and non-hemophilic patients, previous reports on this issue in the literature, and patient opinions...

Lead foreign bodies in joint spaces, often due to projectiles such as bullets, may cause localized arthropathy. There are no reports of joint fracture related to lead arthropathy. Additionally, lead foreign bodes embedded in the joint space may be a source of systemic lead absorption, causing elevated blood lead levels and toxicity to other organs. We present a young adult patient with retained left hip joint bullet fragments who developed suspected lead arthropathy and subsequent acute left hip fracture, as well as systemic lead absorption demonstrated by elevated blood lead levels...
