This anti-histidyl tRNA Synthetase antibody is commonly seen in patients with pulmonary manifestations of the syndrome. The following are other possible antibodies that may be seen in association with antisynthetase syndrome: Anti-PL-7, Anti-PL-12, Anti-EJ, Anti-OJ, Anti-KS, Anti-Zo, Anti-Ha (YRS, Tyr). [33]
Statin-associated autoimmune myopathy (SAAM), also known as anti-HMGCR myopathy, is a very rare form of muscle damage caused by the immune system in people who take statin medications. [1] However, there are cases of SAAM in patients who have not taken statin medication, and this can be explained by the exposure to natural sources of statin ...
Polymyositis and the associated inflammatory myopathies have an associated increased risk of cancer. [3] The features they found associated with an increased risk of cancer were older age, age greater than 45, male sex, difficulty swallowing, death of skin cells, cutaneous vasculitis, rapid onset of myositis (<4 weeks), elevated creatine kinase, higher erythrocyte sedimentation rate and higher ...
People with scleromyositis have symptoms of both systemic scleroderma and either polymyositis or dermatomyositis, and is therefore considered an overlap syndrome. Although it is a rare disease, it is one of the more common overlap syndromes seen in scleroderma patients, together with MCTD and Antisynthetase syndrome .
Myositis is a rarely-encountered medical condition characterized by inflammation affecting the muscles. [2] The manifestations of this condition may include skin issues, muscle weakness , and the potential involvement of other organs. [ 3 ]
The sharp criteria also excludes anyone with a positive anti-Sm antibody. [69] It has a sensitivity of 42% [70] and a specificity of 87.7%. [32] Major criteria: [69] Myositis; Pulmonary involvement: Diffusion capacity < 70% of normal values; Pulmonary hypertension; Proliferative vascular lesions on lung biopsy; Raynaud's phenomenon or ...
Respiratory symptoms occur in about 40% of people with dermatomyositis, and in these people, the symptoms may slowly progress and frequently are identified as an eventual cause of death. The main driver of respiratory failure in most of these patients is the damage to the lung interstitia, rather than diaphragm weakness. [3]
This acute viremia is associated in virtually all people with the activation of CD8 + T cells, which kill HIV-infected cells, and subsequently with antibody production, or seroconversion. The CD8 + T cell response is thought to be important in controlling virus levels, which peak and then decline, as the CD4 + T cell counts rebound.
