1/34. Detection of anti-ADAM 10 antibody in serum of a patient with pulmonary fibrosis associated with dermatomyositis.OBJECTIVES: It has been suggested that the humoral immune system plays a part in the pathogenesis of pulmonary fibrosis. Although circulating autoantibodies to lung protein(s) have been suggested, few lung proteins have been characterised. The purpose of this study is to determine the antigen recognised by serum of a patient with pulmonary fibrosis associated with dermatomyositis. methods: To accomplish this, anti-small airway epithelial cell (SAEC) antibody in a patient's serum was evaluated using a western immunoblot. RESULTS: An autoantibody against SAEC was found, and the antigen had a molecular weight of 62 kDa. Using the patient's serum, clones from the normal lung cDNA library were screened and demonstrated that anti-SAEC antibody in the patient's serum was against ADAM (A disintegrin and metalloprotease) 10. CONCLUSION: This is the first report that demonstrates the existence of anti-ADAM 10 antibody in a patient with pulmonary fibrosis associated with dermatomyositis.- - - - - - - - - - ranking = 1keywords = myositis (Clic here for more details about this article) |

3/34. Periarticular calcinosis associated with anti-Jo-1 antibodies sine myositis. Expanding the clinical spectrum of the antisynthetase syndrome.We describe a 58-year-old woman who developed interstitial lung disease (ILD), polyarthritis, and anti-Jo-1 antibodies, with no clinical evidence of myositis. Despite successful treatment with corticosteroid and azathioprine for her arthritis and pulmonary condition, she developed deforming arthropathy of the hands, with periarticular calcinosis. The association of anti-Jo-1 antibodies, ILD, and periarticular calcinosis with subluxing arthropathy sine myositis is rare, with few cases reported. This report expands the clinical spectrum of the antisynthetase syndrome, which is broader than previously reported.- - - - - - - - - - ranking = 1keywords = myositis (Clic here for more details about this article) |
4/34. polymyositis, pulmonary fibrosis and malignant lymphoma associated with hepatitis c virus infection.polymyositis has been associated with various viral infections, and a spectrum of immune-related diseases may occur with hepatitis c (HCV) infection. Both polymyositis and HCV infection may be accompanied by pulmonary fibrosis. An association between polymyositis and malignancy has also been reported. We report a 55-year-old woman accompanied cryoglobulinemia with HCV infection and manifesting polymyositis, pulmonary fibrosis and malignant lymphoma. Steroid therapy was effective to improve interstitial pneumonia, polymyositis, and liver function.- - - - - - - - - - ranking = 51.874892357316keywords = polymyositis, myositis (Clic here for more details about this article) |
5/34. Interstitial lung disease in polymyositis and dermatomyositis: analysis of six cases and review of the literature.Interstitial pneumonitis may be the presenting manifestation of polymyositis-dermatomyositis, or may occur later in the evolution of the disease. The clinical picture is characterized by non-productive cough, dyspnea and hypoxemia. The chest radiograph demonstrates interstitial infiltrates with predilection for the lung bases, often with an alveolar pattern in addition. The histopathologic features are those of organizing and interstitial pneumonitis and pleuritis, with variable fibrosis. In the present series, the patients with mixed alveolar and interstitial infiltrates on chest radiograph and organizing pneumonia and bronchiolitis obliterans in addition to interstitial pneumonitis. In one patient evolution from pulmonary inflammation to interstitial fibrosis was demonstrated. The etiology of primary lung disease in PM-DM is not known, but cell-mediated autoimmunity to an unidentified component of lung tissue is suggested. Including the present series, 50 percent of patients have responded favorably to corticosteroids with decreased dyspnea, clearing of the chest radiograph and improved pulmonary function tests.- - - - - - - - - - ranking = 64.635282113312keywords = polymyositis, myositis (Clic here for more details about this article) |
6/34. Fatal interstitial pulmonary fibrosis in anti-Jo-1-negative amyopathic dermatomyositis.Amyopathic dermatomyositis (DM) describes a subpopulation with the cutaneous eruption of DM, but without muscle involvement. Interstitial pulmonary fibrosis is a recognized complication of DM, often correlated with antisynthetase enzymes, such as anti-Jo-1. We describe a case of fatal IPF in a patient with anti-Jo-1 antibody-negative amyopathic DM.- - - - - - - - - - ranking = 0.83333333333333keywords = myositis (Clic here for more details about this article) |
7/34. Antibodies to glycyl-transfer rna synthetase in patients with myositis and interstitial lung disease.OBJECTIVE. We have previously described anti-EJ antibodies, and provided evidence that these antibodies react with glycyl-transfer rna (gly-tRNA) synthetase. The aim of the present study was to identify patients with anti-EJ antibodies and describe the clinical associations of the antibody, in particular, whether it is associated with the syndrome of myositis and interstitial lung disease (ILD) that has been previously associated with autoantibodies to the aminoacyl-tRNA synthetases for histidine, threonine, and alanine. methods. Sera from patients with suspected or proven polymyositis or dermatomyositis (DM), sera with anticytoplasmic patterns, and control sera were tested for anti-EJ antibodies by immunoprecipitation (IPP). Positive sera and controls were tested for the ability to inhibit gly-tRNA synthetase by preincubation of the enzyme source with the serum. RESULTS. Anti-EJ antibodies were demonstrated in the sera of 5 patients, by IPP of characteristic tRNAs and protein. Original serum EJ and each of the new sera significantly inhibited the enzymatic activity of gly-tRNA synthetase but not histidyl-tRNA synthetase. All 5 of the new patients had inflammatory myopathy, a typical DM rash, and ILD. One, who had an overlap syndrome with systemic lupus erythematosus, had anti-EJ at least 4 months before the development of clinical myositis. arthritis and Raynaud's phenomenon, other features associated with antisynthetases, were also seen. CONCLUSION. Anti-EJ is associated with the syndrome of myositis and lung disease that is seen in association with other antisynthetases. The finding of specific inhibition of gly-tRNA synthetase by all anti-EJ-positive sera strongly supports the identification of EJ antigen as gly-tRNA synthetase.- - - - - - - - - - ranking = 14.093723089329keywords = polymyositis, myositis (Clic here for more details about this article) |
8/34. Amyopathic dermatomyositis.Amyopathic dermatomyositis (ADM) is a rare condition characterized by skin lesions suggestive of dermatomyositis (DM) without detectable muscle abnormalities after at least 2 years of follow-up. pulmonary fibrosis is uncommon in patients with ADM. CASE REPORT: A 64-year-old woman presented with a 2 years and 6 months history of nondestructive polyarthritis. She had skin changes suggestive of DM, including a pink rash over the face, neck, and forearms; Gottron's papules over the metacarpophalangeal joints; and heliotrope edema of the eyelids. She reported no muscle symptoms. Findings were normal from muscle enzyme assays, electromyography, and muscle biopsies. A diagnosis of ADM was given. Early lung fibrosis was found. Investigations for a tumor were negative. DISCUSSION: ADM is a rare condition that may be an abortive form of DM with a favorable outcome and a lower risk of malignancy compared to classic DM. However, the development of pulmonary fibrosis may cloud the prognosis.- - - - - - - - - - ranking = 1keywords = myositis (Clic here for more details about this article) |
9/34. Clinical manifestations in patients with antibody to PL-12 antigen (alanyl-tRNA synthetase).PURPOSE: Anti-PL-12 antibody is directed at the enzyme alanyl-tRNA synthetase (ARS). Studies have clearly associated anti-Jo-1, also directed at an aminoacyl-tRNA synthetase (histidyl-tRNA synthetase), with a subgroup of myositis marked by a high frequency of interstitial lung disease (ILD) and arthritis. A similar syndrome has been reported in patients with antibodies to PL-12, but few patients have been studied. We describe the clinical manifestations in a new series of patients with antibody to PL-12. patients AND methods: Sera from patients with polymyositis and sera found to contain anticytoplasmic antibodies were screened for antibody to PL-12 by testing for inhibition of ARS enzymatic activity by serum, and by immunoprecipitation. RESULTS: Nine sera inhibited ARS. These nine plus two additional sera with anticytoplasmic antibodies immunoprecipitated an identical pattern of tRNAs and a polypeptide of 110 kd. Of the 10 patients that could be evaluated, eight had some evidence of myositis, including six that satisfied the criteria for myositis. Three of these six, all with dermatomyositis, had severe muscle involvement. Eight of the 10 patients had radiographic evidence of pulmonary fibrosis, and seven of the eight had clinical pulmonary impairment, including four with clinically severe ILD. Joint manifestations were found in five patients, and arthritis was the only clinical problem in one patient. CONCLUSION: We conclude that anti-PL-12, like anti-Jo-1 and anti-PL-7, was frequently associated with the "Jo-1 syndrome" of myositis with ILD. ILD was a major clinical problem in this group of patients.- - - - - - - - - - ranking = 13.593723089329keywords = polymyositis, myositis (Clic here for more details about this article) |
