A case of eosinophilic polymyositis is reported. Tender muscle swelling was followed by proximal weakness, creatinine kinase elevation, and electromyographic features typical of polymyositis. Severe myocarditis, pericarditis and heart failure were present. Muscle biopsy specimen showed active myositis with eosinophil infiltrate. Unlike previous cases, blood eosinophils count was normal. The clinical response to corticosteroids was excellent, and a relapse occurring as steroid dose was lowered responded rapidly to an increased dose of prednisolone. Eosinophilic polymyositis may be a component of a general systemic illness with prominent cardiac involvement.

Serum cardiac myosin light chain I (LCI) levels were quantitated using a radioimmunoassay kit in patients suspected of dilated cardiomyopathy (DCM). In this study, 55 patients were evaluated between 1986 and 1991. They were composed of 40 males and 15 females, and their age was 27-75 years (51 +/- 11 years). The patients with renal dysfunction were excluded due to their serum creatinine levels (greater than 2.0 mg/dl). 1) After cardiac catheterization, endomyocardial biopsy and echocardiography, 44 patients were diagnosed as DCM, 2 as ischemic heart disease, 2 as chronic myocarditis, 1 as restrictive cardiomyopathy, 1 as dilated hypertrophic cardiomyopathy, 1 as cardiac amyloidosis, 2 as myopathy, 1 as polymyositis and 1 as hypothyroidism. 2) Only two patients with DCM had elevated LCI. Besides, two patients with myopathy or hypothyroidism had elevated LCI. 3) In the follow-up, one patient died suddenly 6 months later and another showed normal value of LCI four years later. 4) LCI elevation in DCM was not related to either the severity of heart failure or cardiac function and it showed no finding of 201Tl myocardial defect or elevated CPK. 5) The mechanism for elevated LCI in myopathy is related to a cross-reaction with myosin light chain in the skeletal muscle. In hypothyroidism, it may be related to decreased clearance of normal LCI concentration or increased myosin light chain from damaged skeletal muscle. In conclusion, it is evident that the measurement of LCI is not helpful in clinical assessment of patients with DCM, but may be useful in detection of secondary cardiomyopathy.

Idiopathic inflammatory myopathy, a category encompassing polymyositis, dermatomyositis, and a number of other disorders, is very uncommon, but has been the focus of intense study in the Arthritis and Rheumatism Branch of the National Institute of Arthritis and Musculoskeletal and Skin Diseases for the past several years. We describe the clinical picture, stressing the need for biopsy to ensure correct diagnosis. It is especially important to recognize the treatment-resistant variant, inclusion body myositis. The extraskeletal manifestations, particularly the cardiopulmonary, oropharyngeal, gastrointestinal, and endocrine involvement, are described. The cardiopulmonary involvement, especially interstitial lung disease, arrhythmias, and cardiac failure, may dominate the clinical picture. The known causes are varied, and include drugs, toxins, and some infectious agents, however, in most cases a cause cannot yet be identified. Circumstantial evidence suggests that picornaviruses may initiate some cases in humans, and a very similar disease in mice caused by a picornavirus is actively under study. Studies of autoantibodies and cellular immune function support a central role for disordered immunity in the pathogenesis. The myositis-specific autoantibodies, especially those directed at certain enzymes important in protein synthesis (the aminoacyl-transfer RNA synthetases), are found in a clinically distinct subset of patients. Although most patients respond initially to corticosteroids, cytotoxic drugs are sometimes added when steroid toxicity or refractoriness develops. We describe several newer therapies under study for such cases and outline future directions in research.

A patient with photosensitivity is described who presented with an overlap syndrome combining features of systemic lupus erythematosus with a mild polymyositis and scleroderma and with symptoms of the sicca syndrome. In addition, he was anti-SSA/Ro positive and had a constellation of antibodies directed to ENA including the anti-SL-Ki antibody. The condition was fatal and he died from heart failure and respiratory insufficiency.

A patient is described who had polymyositis with arthritis, keratodermia blenorrhagica, pulmonary fibrosis, and cardiac failure with a right bundle branch block. The cutaneous lesions on his palms and soles, considered to be specific for Reiter's syndrome, pointed to an overlapping of polymyositis with features of this syndrome. Findings typical of myositis were present. In addition a muscle biopsy showed sarcolemmal and endomysial deposits of IgG and IgM, and the serum level of IgM was elevated. Because skin lesions appeared at the height of symptoms in other organs, the possibility is raised that both might stem from a common immune process.

Among 2175 patients seen over the last three years in a non-specialized department of internal medicine with no intensive care unit, 100 had supranormal serum lactic dehydrogenase activities. These patients' case-reports have been analyzed. Nearly half the patients (47/100) had a malignant disease (cancer or hemopathy). Among the remaining patients, 19 had a hepatic disorder (alcohol hepatitis in 10, viral hepatitis in 8, and isoniazide hepatitis in 1), 7 had a heart disease (heart failure with hepatomegaly in 5, myocardial infarction in 2), and 27 had various other conditions (including hemolysis in 6 and polymyositis en 3). The value of serum LDH assay is obvious in situations other than acute conditions such as myocardial infarction of pulmonary embolism; these are better known and have not been studied here as their prevalence was low among the patients enlisted in our study. In comparison to other enzymes (alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), transaminases (GOT, GPT) that were also routinely assayed in our patients, abnormal serum LDH activities are much less common and their significance is quite different. An increase in serum and their significance is quite different. An increase in serum LDH activity indicates a serious condition, often with a fatal outcome. The "various other conditions" group includes patients with hemolysis, hepatitis and myositis; the other patients in this group either had severe infectious diseases or died suddenly in the first few days of their hospitalization before diagnosis had been established. Each etiologic group has been analyzed to asses the characteristics of patients with increased LDH activity according to each etiology. Analysis of coincident abnormalities of the other enzymes listed above shows marked differences between etiologic groups; diagnostic accuracy can thus be enhanced in certain conditions. Most patients with malignancies had poorly differentiated tumors, with metastases: 28 had an epithelial tumor, with hepatic and/or bone metastases in 23 cases, 5 had cancer of the liver, 10 had a malignant hemopathy (2 lymphomas, 5 myeloproliferative syndromes, 3 acute leukemias), and 4 had a sarcoma. Cancer of the lung is the most common malignancy (10 cases) and may be responsible for increased serum LDH activity even in patients without metastases. Serum LDH assay is of value for monitoring the course in patients with initially increased activities as it falls under effective therapy and rises during exacerbations.

The overall prognosis for polymyositis and dermatomyositis has improved with the judicious use of corticosteroids, while azathioprine and other cytotoxic agents are of value in improving functional ability and decreasing the total steroid requirement. However, the duration of therapy and the relative risks of it must be under constant surveillance. Problems such as respiratory or cardiac failure in the course of the disease are of serious importance and require particular care in management . Finally, the possibility of neoplasm underlying the disease or occurring as a sequel to cytotoxic therapy should always be borne in mind.

Pulmonary hypertension is an uncommon but lethal complication of polymyositis. A 69-year-old woman is described who had a 20-month history of polymyositis and cardiac failure and in whom severe pulmonary hypertension was noted terminally when she was first seen at our clinic. She died within 24 hours of admission, and autopsy revealed severe plexogenic pulmonary vascular disease.

We report the case of a 28-year old asthmatic female patient, who developed an acute heart failure beginning with diarrhea, fever, and dyspnea 5 weeks after delivery. After improvement of all vital functions and dismissal from hospital care unit a marked blood hypereosinophilia, left ventricular congestive heart failure, pericardium effusion and fever up to 40 degrees C followed. Endomycardial, bone marrow and skeletal muscle biopsies and the pericardial fluid showed a marked eosinophilic infiltration or polymyositis, respectively, which could be treated successfully with steroids and azathioprin. During steroid medication cytomegalovirus-associated myocarditis developed and was diagnosed by in situ hybridization. CMV hyperimmunoglobulin treatment (Cytotect, Biotest) was started (2 ml/kg bw on day 1 and 3, and 1 ml/kg on days 5, 7 and 9), which led to the eradication of the residual infiltrate and CMV-DNA in the myocardium. After discontinuation of all medication, eosinophilia and asthma recurred so that immunosuppressive treatment was continued.

Cardiac involvement in polymyositis is more prevalent than previously assumed. A 59-year-old and a 58-year-old man presented with cardiac involvement preceding skeletal muscular lesions, admitted because of increased levels of muscle-derived enzymes and left ventricular dysfunction with ECG abnormalities. Coronary angiography revealed no stenotic lesions. Right ventricular endomyocardial biopsy disclosed myocarditis. Left ventriculography showed local asynergy of cardiac wall motion. After admission the weakness and atrophy of skeletal muscles progressed gradually and high levels of muscle-derived enzymes persisted. Electromyography and skeletal muscle biopsy confirmed the clinical diagnosis of polymyositis. Both patients were diagnosed as having polymyositis with cardiac involvement, and treatment with steroids was started. Symptoms improved significantly, and the CK enzyme level was reduced effectively. The condition of one patient was well controlled, but the other suffered from repeated heart failure due to severe left ventricular dysfunction. The clinical spectrum of polymyositis is wide and variable. Further studies are needed to evaluate the detection, management, and prognosis of the disease as well as the pathogenesis and to prevent progression of cardiac involvement.
