In eight women with polymyositis (three patients), systemic lupus erythematosus (SLE) (three patients), rheumatoid arthritis (one patient) and shoulder-hand syndrome (one patient), weakness developed during high dose prednisone therapy. These women were studied using serial functional and manual muscle tests, determination of serum glutamic oxaloacetic transminase (SGOT), creatine phosphokinase (CPK) and serum aldolase levels, and urinary excretion of creatine. Insidious onset of weakness was characteristic. Myalgias were seen in five patients and unusual sudden weakness in two. Weakness was always most severe in the pelvic girdle muscles; there was a lesser involvement of shoulder girdle and distal muscles. Serum muscle enzyme levels were normal in all cases, but urinary creatine excretion was invariably increased and proved to be the most sensitive laboratory indicator for clinical diagnosis and for monitoring patient improvement. Serial urinary creatine excretion and serum enzyme studies were of value in differenting steroid myopathy from a flare of myositis in patients with connective tissue disease. Diagnosis and effective management were achieved by the use of readily available laboratory and clinical procedures without resorting to muscle biopsy.

In 200 patients with neuromuscular diseases the author studied malonic dehydrogenase and lactic dehydrogenase activity comparing it with the activity of serum creatine kinase and aldolase. A significant rise in the values of all these enzymes was found only in the Duchenne type of muscular dystrophy, in polymyositis, and less frequently in the limb-girdle type of muscular dystrophy. Raised activity of creatine kinase and sidolase was observed in mothers and sisters of patients with Duchenne type of dystrophy, in patients with non-progressive myopathy, periodic paralysis, amyotrophic lateral sclerosis and polyneuropathy. With progression of dystrophy the activity of these enzymes decreases.

The results of interpretation of muscle biopsies were compared retrospectively to activities of serum enzymes and isoenzymes. A total of 137 patients seen at the Cleveland Clinic Foundation in 1986 and 1987 were included in this study. Serum enzymes evaluated were CK, AST, LD, and aldolase (ALS), as well as the percentage CK-MB isoenzyme. The units of CK-MB and the ratios of CK to AST, LD, and ALS were calculated. Descriptive statistics, Kruskal-Wallis one-way analysis of variance, and stepwise logistic regression were performed. A diagnostic algorithm was constructed using a computer-assisted rule generation program. Myopathic diseases yielded a greater mean increase in serum enzyme activity than atrophic diseases. By multivariate stepwise logistic regression, increases in serum AST and CK activity were independently associated with the presence of inflammation in a muscle biopsy specimen. The diagnostic algorithm allowed for the separation of myopathies from atrophies and could identify cases of Duchenne's muscular dystrophy and polymyositis.

A case of polymyositis (PM) associated with abnormal creatinine phosphokinase (CPK) isoenzyme pattern and Thallium-201 (Tl-201) myocardial imaging was reported. No such case has ever been reported in Japan. A 44-year-old female was admitted for evaluation of muscular weakness of proximal limbs and polyarthralgia. On laboratory examinations, the serum levels of CPK, aldolase and transaminase were markedly elevated. The electromyograms revealed a typical myogenic pattern. On the pathological findings, the principal changes in muscle tissue consisted of inflammatory cell infiltration. Based on those findings, she was diagnosed as having polymyositis. In our patient, there were three characteristics as following; (1) CPK-MB of CPK isoenzyme showed persistent high levels, (2) macro CPK in Electrophoresis of CPK was observed, (3) Tl-201 myocardial imaging revealed multifocal perfusion defects and localized defect in left ventricular inferior wall. She was started on therapy with prednisolone (30 mg/day). The clinical and laboratory manifestations were improved. Abnormal CPK isoenzyme pattern and myocardial imaging were also improved parallel with disease activity of PM. Thus, this case indicated the relation of the damage of skeletal muscle and cardial involvement in PM to unusual CPK isoenzyme pattern. Then wer reported this case.

A patient with Graves' disease associated with severe muscle weakness who was finally diagnosed as polymyositis by pathological examination of the muscle is reported. A 28-year-old women was incidentally found to have hyperthyroidism when she consulted a hospital for the evaluation and treatment of anemia in 1979. She was treated with methimazole for approximately a month when she stopped the medication by herself. Approximately two yr later (Nov. 4, 1981) she consulted another hospital with complaints of palpitation and muscle weakness. Diagnosis of hyperthyroidism due to Graves' disease and thyrotoxic myopathy were made, followed by the treatment with radioiodine (4 mCi of 131I). She was further treated with propylthiouracil (PTU). Four yr after the treatment, serum thyroid hormone concentration declined to the lower level than normal and serum TSH concentration increased. She was subsequently treated with synthetic I-T4. Despite the fact she became euthyroid with the treatment, muscle weakness as well as elevated concentrations of muscle enzymes were not improved. Muscle biopsy was made in July 1983, and she was diagnosed as immune polymyositis and treatment with prednisolone and cyclophosphamide in addition to PTU or I-T4, was started. With the treatment, serum LDH decreased to the normal range. However she still has muscle weakness and serum concentrations of CPK and aldolase are still in higher levels than normal range.

A case of polymyositis with repeated dysphagia and muscle weakness associated with peculiar findings of skin was reported. The patient was a 67-year-old man. His birth and development was normal. There was no family history of neuromuscular disease. On 26th March 1987 he was admitted to a hospital because of dysarthria and dysphagia after fever and diagnosed as having viral myositis. His conditions improved spontaneously with bed rest and he left hospital on 14th April. On 23rd April he had chill and sore throat with fever. On 27th he was admitted to the same hospital because of dysarthria and muscle weakness of the proximal portion of the upper limbs. These symptoms also improved with bed rest. He had repeated these symptoms several times and then he was admitted to our hospital on 12th June. On examination he showed the skin pigmentation under the right eye and the eruption in the back of hands and the buttocks. Muscle weakness was observed in the proximal portion of the upper limbs and the neck flexor. Laboratory tests in admission were as follows: sGOT 49 mU/ml, sGPT 104 mU/ml, LDH 1064 mU/ml, CPK 565 mM/ml, aldolase 25.2 IU/1/37 degrees C. Electromyography showed the typical myogenic changes and biopsy of left biceps brachii revealed inflammatory cells in the muscle fiber which are specific to polymyositis. Immuno-histochemical study is performed to analyse the subpopulation of mononuclear cells in biopsied muscle and skin. Mononuclear cells infiltrated into perimysium, endomysium and epidermis were positive for T11 and T8, but less positive for T4, B1 and Leu11. On the basis of these findings he was diagnosed as having "polymyositis syndrome".

An effort was made to identify all patients with polymyositis/dermatomyositis (PM/DM) admitted to hospitals in Israel from 1956-1976. The diagnosis of PM/DM was retrospectively reviewed in 92 (46 definite, 26 probable, and 20 possible) cases. The most common complaints and physical findings in the course of the disease were muscle weakness (86 patients), rash (53 patients), arthritis or arthralgia (39 patients), and dysphagia (35 patients). Elevated serum aldolase levels were found in 64% of the patients for whom data were available; 92% had abnormal electromyogram results, and 60.9% had muscle histopathology consistent with PM/DM. Malignancy was diagnosed in 13 patients. Malignancy, ischemic heart disease, and pulmonary complications were the most common causes of death. The actuarial survival curve was heterogeneous, with an accelerated mortality during the first year after diagnosis and a slower mortality during the following 7 years. Independent unfavorable prognostic signs were: failure to induce remission, leukocytosis, fever, older age, a shorter disease history, and dysphagia.

The aim of the present work was to investigate histological localization of newly found human muscle CA-III and its diagnostic value in neuromuscular diseases. The following results were obtained. CA-III was purified as a single band from human skeletal muscle nd specific anti-CA-III antiserum was raised in the rabbits. By the direct immunoperoxidase method in human biceps muscle, CA-III was localized mainly in Type I fibers (red muscle type). A radioimmunoassay was developed for CA-III which can detect 5 ng/ml of sample. Among several human tissues, CA-III was found virtually specific to the skeletal muscles with a level of 5 mg/gm wet tissue. Normal serum CA-III level (n = 20) was 22.5 +/- 15.3 (SD) ng/ml. Among 140 cases of various diseases, elevated serum CA-III levels were found in 29 cases, all of which were only from neuromuscular diseases including 17 various muscular dystrophies, 5 polymyositis, 2 other myopathies and 5 ALS. In acute myocardial infarction with highly elevated CPK, serum CA-III remained normal. In 60 cases of various neuromuscular diseases, serum CA-III, CPK and aldolase were measured. Order of sensitivity (% frequency of elevated serum level) was CPK greater than CA-III greater than aldolase, however, CA-III was most frequently elevated in myotonic dystrophy which predominantly affects Type I fibers. In 15 ALS, raised CA-III was found in 5 cases, which were all in relatively early stages showing rapidly progressive clinical courses. This result raises a possibility to use serum CA-III for evaluation of the prognosis in ALS. It is concluded that CA-III is clinically applicable as a new diagnostic marker for muscle diseases, and probably reflects Type-I fiber abnormalities more sensitively than CPK and aldolase.

An increased frequency of diffuse interstitial lung disease (DILD) was found in 7 of 15 cases of polymyositis and dermatomyositis seen in a 7-yr period. Affected patients had higher values of creatine phosphokinase and aldolase and more severe muscle necrosis than 8 patients with DILD. Early corticosteroid therapy sufficient to normalize enzymes apparently led to better resolutions of DILD. Active muscle necrosis seemed to be related to the development of DILD.

We attempt to correlate the patient's disability and serum enzymes (creatinekinase, lactic dehydrogenase, aldolase, glutamic oxalacetic and glutamic piruvic transaminase) in several neuromuscular disorders using the Vignos and Archibald scale (V&A). In 806 cases we studied, serum enzyme levels and the V&A disability using a computer for Pearson's correlation and regressive analysis. A good correlation of the V&A with age suggested a progressive evolution (increased disability) in Duchenne muscular dystrophy, fascioscapulohumeral dystrophy, myotonic dystrophy, myopathies due to respiratory chain enzyme deficiency and amyotrophic lateral sclerosis. A negative correlation (decrease disability with age) was found for multicore myopathy, benign myopathy of childhood with type 1 predominance, carnitine myopathy deficiency and dermatomyositis. It was found a correlation (p < 0.05) of the V&A and the level of specific serum enzymes with Duchenne muscular dystrophy, oculocraniosomatic dystrophies, polymyositis and polyarteritis nodosa. Using regression analysis, we found a weak interrelation between serum enzymes studied simultaneously and the V&A. These weak relations suggest some limitation in the long term use of the five serum enzymes in the evaluation of neuromuscular disorders when compared with V&A; although they are very important in the diagnosis.
