An autoantibody known as anti-Jo-1 antibody is found in 25% of patients with myositis. Its prevalence in patients with both myositis and cryptogenic fibrosing alveolitis was 68% (13 out of 19 patients), compared with 7.5% in patients with myositis alone (four of 53) and 3% in patients with cryptogenic fibrosing alveolitis alone (two of 62). Anti-Jo-1 antibody may be useful in indicating patient...
BACKGROUND Orbital myositis is a rare extra-intestinal manifestation of inflammatory bowel disease. Seventeen cases of Crohn's disease associated orbital myositis and 3 cases of ulcerative colitis associated orbital myositis have been reported in the published literature since 1970. We report the use of adalimumab (Abbott, Canada, Inc.) for orbital myositis in a patient with Crohn's disease who...
BACKGROUND In human and animal prion diseases, pathological prion protein, PrPSc, as well as prion infectivity is mainly found in the central nervous system, but also in lymphoid organs and muscle. Pathophysiology of prion colonization of lymphoid organs has been studied intensively, yet how myositis influences prion accumulation in muscle is unknown. RESULT We have investigated the influence...
Idiopathic inflammatory myopathies (IIM) are traditionally identified as a group of disorders that target skeletal muscle due to autoimmune dysfunction. The IIM can be divided into subtypes based on certain clinical characteristics, and several classification schemes have been proposed. The predominant diagnostic criteria for IIM is the Bohan and Peter criteria, which subdivides IIM into primar...
OBJECTIVE To analyze clinical characteristics, survival and causes of death of patients diagnosed with autoimmune inflammatory myositis in the REMICAM registry from the Society of Rheumatology in the Community of Madrid (SORCOM). METHODS Multicenter cohort of patients diagnosed with autoimmune inflammatory myopathy with follow-up between January 1980 and December 2014. A total of 313 variable...
PURPOSE OF REVIEW Defined autoantibodies are found in about half of the patients with myositis. Traditionally, these autoantibodies have been divided into myositis specific autoantibodies (MSAs) and myositis associated autoantibodies. Several studies have shown that MSAs are associated with specific clinical characteristics and can aid our understanding of the pathophysiology of myositis. REC...
BACKGROUND About 50% of patients with thymoma have paraneoplastic myasthenia gravis (MG). Myositis and myocarditis or neuromyotonia (NMT) will also develop in some. Patients with thymoma-associated MG produce autoantibodies to a variety of neuromuscular antigens, particularly acetylcholine receptor (AChR), titin, skeletal muscle calcium release channel (ryanodine receptor [RyR]), and voltage-ga...
The idiopathic inflammatory myopathies or myositis syndromes (the most common forms are polymyositis, dermatomyositis, and inclusion body myositis) are systemic autoimmune diseases defined by chronic muscle weakness and inflammation of unknown etiology and result in significant morbidity and mortality. Research suggests that categorizing heterogeneous myositis syndromes into mutually exclusive ...
Widespread periarticular new-bone formation (myositis ossificans) was studied in 45 patients with brain damage who were in long-term coma. Thirty-six of these patients displayed myositis ossificans around at least one major joint. The development of myositis ossificans was shown to be independent of the sex and age of the patient and also of the aetiology, duration and outcome of the coma. Radi...
PURPOSE Some patients with interstitial lung disease (ILD) related to connective tissue disease (CTD) have a delayed diagnosis of the underlying CTD when the ILD is categorized as idiopathic. In this study, we evaluated the frequency of myositis autoantibodies in patients diagnosed with idiopathic ILD and investigated the clinical significance stemming from the presence of the antibodies. MAT...
