The tendon enthesis originates from a specific pool of hedgehog-active Gli1+ progenitor cells that differentiate and produce mineralized fibrocartilage. The current study investigated the regenerative capacity of this cell population by comparing the responses of early postnatal and mature entheses to injury. Lineage tracing studies demonstrated that the original Gli1+ cell population had the capacity to heal immature entheses after injury but this capacity was lost after the cells differentiated into mature fibrochondrocytes...

Apremilast (Otezla(®)) is an orally administered, small molecule inhibitor of phosphodiesterase 4 (PDE4). Apremilast 30 mg twice daily reduced the severity of moderate to severe plaque psoriasis in the phase 3 ESTEEM trials, as well as improving difficult-to-treat nail, scalp and palmoplantar psoriasis. Most patient-reported outcomes, including pruritus and the total Dermatology Life Quality Index, also improved to a significantly greater extent with apremilast than with placebo, with significant improvements in pruritus and skin discomfort/pain visual analogue scale scores seen as early as week 2 with apremilast...

BACKGROUND: IL36RN encodes the IL-36 receptor antagonist (IL-36Ra), and loss-of-function mutations in IL36RN define a recessively inherited autoinflammatory disease named "deficiency of IL-36Ra" (DITRA). DITRA causes systemic autoinflammatory diseases, including generalized pustular psoriasis (GPP), an occasionally life-threatening disease that is characterized by widespread sterile pustules on the skin, fever and other systemic symptoms. GPP can present at any age, and provocative factors include various infections, medicines and pregnancy...

Peripheral spondyloarthritis (SpA) is a common extraintestinal manifestation in patients with active inflammatory bowel disease (IBD) characterized by inflammatory enthesitis, dactylitis, or synovitis of nonaxial joints. However, a mechanistic understanding of the link between intestinal inflammation and SpA has yet to emerge. We evaluated and functionally characterized the fecal microbiome of IBD patients with or without peripheral SpA. Coupling the sorting of immunoglobulin A (IgA)-coated microbiota with 16S ribosomal RNA-based analysis (IgA-seq) revealed a selective enrichment in IgA-coated Escherichia coli in patients with Crohn's disease-associated SpA (CD-SpA) compared to CD alone...

Interfaces between tendon/ligament and bone ("entheses") are highly specialized tissues that allow for stress transfer between mechanically dissimilar materials. Entheses show very low regenerative capacity resulting in high incidences of failure after surgical repair. Tissue engineering is a promising approach to recover functionality of entheses. Here, we established a protocol to decellularize porcine entheses as scaffolds for enthesis tissue engineering. Chemical detergents as well as physical treatments were investigated with regard to their efficiency to decellularize 2 mm thick porcine Achilles tendon entheses...

ERAP1 single nucleotide polymorphisms (SNP) are associated with ankylosing spondylitis. Data on ERAP1SNPs in juvenile idiopathic arthritis (JIA) is scarce. ERAP1 rs30187 SNP was shown to confer risk in the enthesitis-related arthritis (ERA) category of JIA. We examined the prevalence and association of this SNP in Indian children with ERA. SNPs in ERAP1 (rs30187) were genotyped in children with ERA (n = 271), ankylosing spondylitis (AS) (n = 213) and healthy controls (n = 101), using Taqman genotyping...

The cruciate ligaments are components of the knee capsuloligamentous system providing vital neurosensory and biomechanical function. Since most historical primary ACL repair attempts were unsuccessful, reconstruction has become the preferred surgery. However, an increased understanding of the efficacy of lesion-site scaffolding, innovative suturing methods and materials, and evolving use of biological healing mediators such as platelet-rich plasma and stem cells has prompted reconsideration of what was once believed to be impossible...

Psoriatic arthritis (PsA) accounts for around 20% of referrals to the early arthritis clinic and presents a significant diagnostic and management challenge. Early diagnosis is important to prevent long term functional disability and to ensure optimal management of arthritis and key comorbidities. From the rheumatologist's perspective, the differential diagnosis includes rheumatoid arthritis, gout and other inflammatory arthritides. Once diagnosed, it is essential to assess the disease fully, including arthritis, enthesitis, dactylitis, skin/nail disease and axial involvement...

BACKGROUND: Due to the clinical heterogeneity of psoriatic arthritis (PsA), recommendations have been developed by international groups to guide therapeutic decisions of the rheumatologist. The objective of the current systematic review (RS) was to evaluate the evidence of efficacy of disease-modifying antirheumatic drugs (DMARDs) in PsA. METHODS: Literature search in Medline, EMBASE, Cochrane Library, from 2008 to 2014. We included RS, randomized clinical trials and observational studies, in patients with PsA and an evaluation of efficiency of conventional DMARDs (methotrexate, sulfasalazine, leflunomide), according to the following outcomes: peripheral and axial symptoms; peripheral radiological damage; enthesitis according to power Doppler ultrasound or magnetic resonance imaging (enthesitis count before and after therapy); dactylitis; uveitis...

: The tendon-to-bone attachment (enthesis) is a complex hierarchical tissue that connects stiff bone to compliant tendon. The attachment site at the micrometer scale exhibits gradients in mineral content and collagen orientation, which likely act to minimize stress concentrations. The physiological micromechanics of the attachment thus define resultant performance, but difficulties in sample preparation and mechanical testing at this scale have restricted understanding of structure-mechanical function...

Involvement of tendons and tendon sheaths is frequently found in the most common inflammatory systemic diseases, rheumatoid arthritis and spondyloarthritis. In rheumatoid arthritis tendon manifestations occur as tenosynovitis, with swelling and pain of the tendons mainly on the hands and feet. In spondyloarthritis the involvement of tendons presents as enthesitis with pain and swelling directly at the attachment points of tendons to the bony structures and more commonly in the lower extremities. Pathological alterations of tendons can be normally visualized by sonography and only sometimes with magnetic resonance imaging (MRI) or scintigraphy...
