Idiopathic inflammatory myopathies lead to important functional limitations resulting from the loss of muscle strength and endurance, especially in the hip and shoulder, which leads to a significant loss of quality of life for patients. The aim of this study is to correlate the "Myositis Functional Index-3 (FI-3)" with muscle function assessed by computerized isokinetic dynamometry, electromyography and magnetic resonance through an observational study; and to compare the effects of a repetitive task training program with a resistance exercise program through an interventional study in patients with inflammatory myopathies. It is expected that FI-3 will present a good correlation with muscle function assessed by computerized isokinetic dynamometry and electromyography, given its reduced cost and less time spent on evaluation. It is also expected to demonstrate that repetitive task training is as efficient and safe as resistance exercises.
This study is a prospective observational study. We aim to investigate the safety and efficacy of inactivated SARS-CoV-2 vaccine between immune-related myopathy (myasthenia gravis and inflammatory myopathy) patients and health controls. The main study factors include adverse events following immunization (AEFI), serum specific antibody (Acetylcholine receptor (AChR) antibody, Anti-MuSK (muscle-specific kinase) antibody, myositis antibody) and virus neutralizing antibody titers.
Antisynthetase syndrome (ASS) is an overlap connective tissue disease characterized by the presence of myositis-specific autoantibodies directed against tRNA-synthetases. Clinical manifestations are myositis, interstitial lung disease (ILD), Raynaud's phenomenon, mechanic's hands and polyarthritis. Clinical presentation varies between ASS patients. ASS is potentially life threatening due to lung involvement, especially in rapidly progressive forms. Anti-histidyl-tRNA synthetase (anti-Jo1) antibodies are the most frequently detected antibodies in ASS (60 % of patients). Anti-threonyl-tRNA synthetase (anti-PL7) and alanyl-tRNA synthetase (anti-PL12) antibodies are each detected in 10 % of patients approximatively. Anti-tRNA-synthetases antibodies are mutually exclusive. Clinical heterogeneity of ASS patients appears to be associated with specific autoantibodies profile. Patients with anti-Jo1 antibodies have a more systemic presentation (especially with muscle involvement), whereas patients with anti-PL7 or anti-PL12 antibodies have more frequent and isolated ILD. If anti-PL7 and anti-PL12 antibodies are associated with more severe ILD and poorer survival is still matter of debate. Aims of this study were to compare ILD severity at diagnosis and clinical course in patients with ASS according to antisynthetase autoantibodies types.
This study aims to explore the clinical and immunological efficacy of low-dose Interleukin-2 (IL-2) and cyclosporin a (CSA) on idiopathic inflammatory myopathy (IIM)
This study aims to explore the clinical and immunological efficacy of low-dose Interleukin-2 (IL-2) on idiopathic inflammatory myopathy (IIM).
Idiopathic inflammatory myopathies (IIM) patients are at high risk of development of reduced bone mineral density due to impairment of functional status due to the disease and a relatively high dose of glucocorticoid use for the treatment. Reduced bone mineral density is prevalent in local IIMs patients. Denosumab and zoledronic acid are established treatments for osteoporosis in postmenopausal women and glucocorticoid-induced osteoporosis. However, the role of these treatments in reduced bone mineral density including osteoporosis and osteopenia related to IIMs are lacking. There is also no evidence on comparing the efficacy of the two agents. Therefore, the investigators conducted this prospective randomized controlled study to compare the efficacies of denosumab and zoledronic acid in treating reduced bone mineral density in IIMs patients. The hypothesis in this study is that treatment by denosumab or zoledronic acid would improve bone mineral density in IIMs patients with reduced bone mineral density.
A prospective observational study to determine the effectiveness of magnetic resonance (MR) imaging in the diagnosis and monitoring of idiopathic myopathy in adult humans.
