The invention concerns KDM5A inhibitors for use in prevention or treatment of idiopathic inflammatory myopathies such as polymyositis, dermatomyositis, necrotizing autoimmune myopathy, and in particular sporadic inclusion body myositis, and diagnosis of these diseases based on KDM5A expression levels in muscle tissue. The invention further concerns pharmaceutical compositions comprising KDM5A inhibitors for use in prevention or treatment of idiopathic inflammatory myopathies such as polymyositis, dermatomyositis, necrotizing autoimmune myopathy, and in particular sporadic inclusion body myositis.

The disclosure concerns a method for assessing muscular dystrophy-linked protein expression in muscle fibers using digital image analysis of tissue. The method relates to assessing disease severity in individuals with muscular dystrophy. Muscle tissue samples are obtained from patients submitted for evaluation and processed to produce tissue sections mounted on glass slides which have been stained for a muscular dystrophy-linked protein. Digital images of the stained tissue sections are generated and analyzed by applying an algorithm process implemented by a computer to the images. The algorithm process extracts the morphometric and staining features of the muscular dystrophy-linked protein staining in the tissue, and parameters relating to these features are used to score the disease status for each patient submitted for evaluation. The score of disease status is ultimately used to infer disease severity, monitor the efficacy of a therapeutic approach, or select patients as candidates for a therapeutic approach.

A method is for correcting a concentration of a bone turnover marker to obtain an adjusted value which gives an indication of an individual's bone health status or amount of changes occurred over time or by treatment while eliminating the influence of possible pre-analytical variability. The method includes: obtaining the concentration of the bone turnover marker of a sample; correcting the obtained concentration using a mathematical model which comprises at least three factors, different from the bone health status, such that for the adjusted value variabilities in the concentration of the bone turnover marker, that are caused by the at least three factors, are substantially filtered out by the mathematical model.

A composition suitable for diagnosing a musculoskeletal disease and a composition suitable for preventing or treating a musculoskeletal disease are disclosed. The composition contains zinc finger protein with KRAB and SCAN domains 8 (Zkscan8) protein, which can be effectively used as an excellent biomarker for obtaining accurate information about the occurrence and progression stages of a musculoskeletal disease, specifically a tendon disease or a ligament disease. The compositions containing Zkscan8 can be effectively used for preventing or treating a musculoskeletal disease through Zkscan8 overexpression.

The invention provides methods and systems for detecting a biomarker in a synovial fluid wherein the system also includes a control to ensure that the test sample is indeed synovial fluid. The biomarkers and the control for synovial fluid can be identified using proteomic methods, including but not limited to antibody based methods, such as an enzyme-linked immunosorbant assay (ELISA), a radioimmunoassay (RIA), or a lateral flow immunoassay.

The present invention in general relates to the field of antibody profiling in spondyloarthritis. In particular, the inventors found that antibody levels against selected peptides are raised in spondylarthritis patients, and herein provide a diagnostic method and kit comprising such peptides for use in the diagnosis of spondyloarthritis.

A pharmaceutical composition for treating cartilage dysplasia, comprising 1-[(3S)-3-[4-amino-3-[2-(3,5-dimethoxyphenyl)ethynyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-pyrrolidinyl]-2-propen-1-one or a pharmaceutically acceptable salt thereof, and a treatment method using the pharmaceutical composition.

The present invention relates to a method for diagnosis of delayed bone fracture healing, comprising determining the frequency of a subpopulation of CD8+ cells selected from a first group comprised of CD8+CD57+, CD8+CD28− and CD8+CD28−/CD57+, in a sample obtained from a subject. The present invention further relates to a system and a kit of parts for prediction and resulting options for preventing of delayed bone fracture healing.

The present invention relates to the discovery that the expression levels of some RNA molecules, comprising messenger RNA (mRNA), non-coding RNA (ncRNA) and/or microRNA (miRNA), and protein can be used as a diagnostic signature to predict or monitor the bone healing ability in an acutely injured subject or in a chronic nonunion subject. In certain embodiments, the invention relates to methods and compositions useful for differentiating between a nonunion, slow healing, and/or normal healing of a fractured bone and treatment recommendations. The invention further includes a kit comprising biomarker probes for assessing the bone healing ability in an acutely injured subject or in a nonunion subject after receiving therapeutic treatment.
