Juvenile dermatomyositis (JDM) is characterized by microvasculopathy of the striated muscle, which indicates different etiology, clinical manifestation and prognosis from the adult-onset dermatomyositis. We experienced 10 cases of JDM and 1 case of juvenile polymyositis (JPM) in the recent 14 years, and analyzed clinical manifestation, laboratory findings, treatment anrognosis. The cases were 9 girls and 2 boys. The onset of the disease was 2 years of age in 2 patients, and 9 to 13 years of age in 9 patients. During the follow-up courses, no cases were dead or complicated with neoplasm. Skin rash was the most frequent manifestation at the onset, and facial erythema was common. Muscle weakness was observed only in 4 cases at the onset, and in all cases muscle enzymes including creatine kinase and aldolase were elevated. The clinical course was classified into three groups; monocyclic (5 cases), chronic and recurrent (4 cases), and fulminant (2 cases). Prognosis depended not on the degree of the elevated serum muscle enzymes, but on the initial therapy employed at the onset of the disease. Five cases including 2 cases of fulminant type were initially treated with methylprednisolon pulse therapy, and all of these had no recurrence. On the other hand, 6 cases were started the therapy with p.o. prednisolone. Four of them had frequent recurrences in accordance with tapering of prednisolone. These cases were effectively treated with the combination with immunosuppressants. In previous reports, JDM and JPM were reported to be a disorder which had relatively favorable prognosis. But we found that one third of the cases had chronic and recurrent courses. Methylprednisolone pulses as initial therapy may be effective in preventing the chronicity and recurrence of the disease.

Somatic mutant frequencies (Mf) were determined using the HPRT T-cell cloning assay of peripheral blood T-lymphocytes from 14 children with juvenile onset dermatomyositis (JDM). Serologic parameters, specifically muscle enzyme determinations in JDM subjects, were correlated with residual lnMf (delta) in these patients to compare T-cell activation with clinical parameters associated with JDM. In addition TCR analysis was performed to determine T-cell proliferation and clonality on 12 HPRT mutant isolates from two individuals with JDM. Statistically significant correlations were found between residual lnMf and the following serologic parameters: aldolase (r = 0.771, P = 0.015); CPK (r = 0.602, P = 0.023); and SGOT (r = 0.656, P = 0.011) in children with JDM. In addition, identical TCR gene rearrangements were identified in 86 and 40% of the HPRT mutant isolates from the two patient samples analyzed, which is a significantly higher level of clonality than the 10-15% expected in normal individuals. These data suggest that determining HPRT Mf can be a useful antigen-independent method of selecting clonally expanding T-lymphocytes in autoimmune disease where relevant antigens are unknown. Future analysis of HPRT mutant isolates from children with active myositis may increase our understand of the activated T-cells involved in this disease.

A 22-year-old male with juvenile dermatomyositis presented with fever up to 40 degrees C and acute pain in his right thigh accompanied by muscle weakness, a skin rash and a tender swelling. Serum aspartate aminotransferase (AST) and aldolase were mildly elevated. C-reactive protein (CRP) and fibrinogen were markedly increased. The differential white blood cell count revealed relative lymphopenia. Radiography showed diffuse calcifications particularly around the thighs and knees of both legs. Magnetic resonance imaging (MRI) demonstrated inflammatory infiltrates in the right thigh. The lesions were identified as phlegmone by immunoszintigraphy with 99mTc-labelled antigranulocyte antibodies. On the 10th day of treatment Staphylococcus aureus was cultured from blood. Patients with juvenile dermatomyositis and calcinosis may develop bacterial infections of soft tissue which sometimes mimic a disease flare. For differential diagnosis plain radiographs, CT scans and MRI are of limited value. Immunoszintigraphy is able to differentiate between infiltrates caused by granulocytes and lymphocytes.

Dermatomyositis (DM) is a rare inflammatory disorder of the skin and muscles associated with an increased incidence of malignancy. We describe herein the case of a 59-year-old woman with DM accompanied by rectal cancer. Following excision of the rectal cancer, the characteristic features of the skin rash such as the heliotrope eyelid rash and Gottron's papules, and proximal muscle weakness, improved. Moreover, the elevated preoperative serum levels of muscle-associated enzymes, including aspartate transaminase, creatine phosphokinase, lactate dehydrogenase, and aldolase, decreased from 38 to 16 (IU/1), 138 to 42 (IU/1), 672 to 515 (IU/1), and 32.2 to 4.3 (IU/1), respectively. The current concepts of the correlation between DM and malignancy are discussed with regard to the present case.

A 53-year-old female suffered from joint pain and muscle weakness in all extremities in 1991. Laboratory data showed increased creatine phosphokinase (CK) and aldolase. Liver dysfunction and weakness of proximal muscles also appeared and polymyositis (PM) was suspected. Two years later, she was diagnosed with dermatomyositis (DM) through skin and muscle biopsy. Because elevation of biliary enzymes and transaminases were continued, liver biopsy was performed in 1997. Histopathological findings of her liver were compatible with primary biliary cirrhosis (PBC). Similar conditions were noticed in her identical twin as well. DM associated with PBC is unusual and cases of monozygotic twins with both conditions are very rare. The difference between PBC and autoimmune cholangitis (AIC) which has recently reported and the genetic influence on the pathogenesis of DM and AIC are also discussed.

A 36-year-old man was admitted to our hospital complaining of cough, dyspnea on exertion, skin eruptions, and joint pain. Characteristic skin lesions such as erythema around the nails, telangiectasis, and edema of the eyelids were observed in this patient. He had never complained of muscle symptoms, and his laboratory examinations showed no elevation of either CPK or aldolase. From several lines of evidence including the skin biopsy findings, amyopathic dermatomyositis was diagnosed. Chest X-ray films showed subpleural funicular opacities and consolidation in both lower lung fields. Lung biopsy specimens taken under video-assisted thoracoscopic surgery revealed nonspecific interstitial pneumonia, group II. Oral prednisolone treatment was initiated at 60 mg daily together with oral cyclosporin A (100-150 mg daily). The minimum serum concentration of cyclosporin A was maintained between 100 and 200 ng/ml. Respiratory symptoms gradually improved, and the oral prednisolone dose was tapered off. Pulmonary function and chest CT findings showed marked improvement.

We described three children with juvenile dermatomyositis (JDM) refractory to the conventional therapy. They were successfully treated with intravenous cyclophosphamide (IVCY) pulses, and two of them were administered plasma exchange (PE) before IVCY. Case 1. A 17-year-old girl with JDM was previously treated for 2 years with the combination of prednisolone, intravenous gamma-globulin, methotrexate, and azathioprine. However, muscle weakness gradually progressed. She failed to hold her sitting position and to rise her arms, but both serum CK and aldolase were stable. After the episode of aspiration pneumonia the follow-up muscle biopsy was performed, which revealed muscle degeneration and massive mononuclear cell infiltration in perivascular area. The erythrocyte sedimentation rate (ESR) and fibrin degradation product E (FDP-E) levels were gradually increased. Because the active inflammation of muscle and muscle vasculature was suspected, the PE and IVCY combination therapy was administered. During the 6 courses of the therapy, muscle weakness was markedly improved so that she could hold herself at the sitting position and could have meals by herself. Case 2. A 5-year-old boy with JDM was treated for 8 months with prednisolone p.o., but his muscle strength became worse. The muscle enzyme levels, such as serum CK and aldolase, were not reflecting his status of the disease, but FDP-E levels were increased. Muscle MRI and biopsy revealed the inflammatory changes of perivascular area of muscle. The PE and IVCY combination therapy was effective, and he became able to walk and run by himself. Case 3. A 14-year-old boy was diagnosed as having JDM when he was 10 years of age, and treated with prednisolone p.o., and subsequently with intravenous methylprednisolone pulses and azathioprine. Three years later the flares were observed accompanied with the elevations of serum CK and FDP-E. The administration of IVCY improved muscle strength as well as serum muscle enzyme and FDP-E levels. These findings indicated that the clinical manifestations of JDM should be closely monitored, that the serum levels of muscle enzymes including CK and aldolase were sometimes not indicative for the flares of JDM, and that muscle MRI and re-biopsy examination were needed for the children with progressive muscle weakness. In addition, determination of ESR and FDP-E was not specific but helpful to detect flares of the disease in some cases.

In a study of 58 patients with various diseases of muscle or of the neuromuscular system, the serum activity of various enzymes was measured. Abnormal elevation of serum activities of aldolase, lactic dehydrogenase and, to a lesser extent, glutamic-oxalacetic transaminase and phosphohexose isomerase, was an almost constant feature in patients with progressive muscular dystrophy. These elevations were very frequent in dermatomyositis, common in acute cerebral vascular accidents, and rarely seen in other neurological disorders. Abnormal serum activity of iso-citric dehydrogenase was not observed in the course of the present study. Supplementary protein feeding of patients with muscular dystrophy had no effect on serum enzyme activity, no consistent effect on urinary creatine excretion and no effect on the strength of the patient or the course of the disease. Dystrophic muscles from a dystrophic strain of mice showed a decrease in activity of lactic dehydrogenase and aldolase below that of control muscle and an increase of iso-citric dehydrogenase activity. These findings, taken with the differences in serum activities of lactic dehydrogenase, aldolase and isocitric dehydrogenase in the dystrophic animals, support the conclusion that dystrophic animals handle these soluble enzymes in quite different ways.

A 61-year-old man was admitted to our hospital because of edematous erythema on his upper eyelids and dry cough. No subjective nor objective findings suggestive of skeletal muscle involvement, such as muscle weakness and elevated levels of aldolase and creatine phosphokinase were noted. Chest high-resolution computed tomography revealed a ground glass opacity and consolidation of his lower lung. Skin biopsy findings were compatible with dermatomyositis. Therefore, he was diagnosed as amyopathic dermatomyositis (ADM) with acute interstitial pneumonia and treatment with steroid pulse therapy was started. Since histological evaluation showed diffuse alveolar damage during the initial treatment, the treatment was changed into the combination therapy of prednisolone and cyclosporine. However, his acute interstitial pneumonia did not respond to this treatment and passed away by aggravation of a breathing state and concurrence of disseminated intravascular coagulation. Japanese patients with ADM have been shown to be more frequently associated with intractable acute interstitial pneumonia than Caucasian patients, suggesting that the racial difference influences the occurrence of acute interstitial pneumonia in ADM. Since autoantibodies specific for ADM have not been detected, we performed immunoprecipitation analysis using 35S methionine-labeled K562 cells to identify them. His sera immunoprecipitated a polypeptide of 140 kDa. The 140 kDa polypeptide might be one of autoantibodies specific for ADM with acute interstitial pneumonia, although future analysis using a larger number of patients with ADM will be required to confirm this result.

Because the clinical significance of von Willebrand factor (vWF), a marker of endothelial injury, has not been well studied in adult patients with dermatomyositis (DM), we evaluated whether plasma vWF levels are useful as an index of disease activity in these patients. We measured plasma vWF antigen levels in 11 patients with active adult DM, 13 patients with inactive DM, and 18 healthy subjects using an enzyme-linked immunosorbent assay. The association of vWF level with clinical condition and muscle-derived enzyme leakage among DM patients was examined using analysis of covariance and logistic regression analysis. Furthermore, we studied the effects of treatment on the vWF antigen level. The mean vWF antigen level was significantly higher in active DM patients than in inactive DM patients and healthy subjects. Higher vWF levels were associated with clinical symptoms, such as general fatigue, fever, and muscle weakness. They were also associated with the levels of aspartate aminotransferase, alanine aminotransferase, and aldolase, but not with those of lactate dehydrogenase and creatine kinase (CK). vWF antigen was correlated with muscle enzymes except for CK. The plasma vWF levels in six patients with active DM significantly decreased after successful corticosteroid treatment. Plasma vWF level may be considered a useful marker of disease activity in adult DM patients.
