Myoglobin was detected in the sera of patients with dermatomyositis, polymyositis, scleroderma, and systemic lupus erythematosus (LE) with active myopathy. Overall, myoglobinemia was detected in 74.1% of sera taken from patients with active myositis before therapy, with slightly greater frequency in the groups with dermatomyositis and polymositis. With steroid therapy, this frequency fell to 43.4% and to 9.5% in patients in clinical remission not requiring therapy. Serum enzyme (creatine phosphokinase, lactic dehydrogenase, and SGOT) activity was higher in samples containing myoglobin, but there was considerable overlap between those with and without myoglobinemia. Sequential serum determinations in six patients demonstrated rapid reduction in the levels of serum myoglobin with therapy, usually before enzyme values had returned to normal. In one patient followed up for 30 months, myoglobinemia correlated with clinically observed exacerbations of rash and weakness to a greater degree than did enzyme determinations.

During a period of 4 years urine samples from 54 patients with systemic lupus erythematosus (SLE) were repeatedly analysed for the activities of lactate dehydrogenase (LDH), leucine aminopeptidase (LAP) and alanine aminopeptidase (AAP). Increased urinary enzyme levels were consistently found in 8 patients with severe lupus nephritis and the nephrotic syndrome, as well as in 9 patients with chronic lupus nephritis resistant to therapy. A further group of 9 patients with lupus nephritis responded favourably to immunosuppressive therapy with arrest of kidney-damaging processes; a concomitant normalization of urinary enzyme levels was observed, giving an accurate reflection of the progression of the disease. Another 14 SLE patients showed raised enzyme levels preceding the development of clinical signs of nephropathy. The last 14 SLE patients displayed neither nephropathy nor altered enzyme activities. The determination of urinary enzyme activities is, therefore, considered to be a useful supplement to the routine biochemical analyses performed on the urine in cases of SLE.

We present the case of a 26-year-old Caucasian woman with systemic lupus erythematosus (SLE) of 9 years duration, mainly involving the kidney. Her clinical course was complicated in the last year by several infectious and noninfectious events, and after pancytopenia, fever, and extremely high levels of lactate dehydrogenase developed, the woman died. Light and electron microscopy of bone marrow, together with immunophenotyping, disclosed malignant histiocytosis, a complication of SLE that has not been reported.

The relationship between the renal pathologic activity of systemic lupus erythematosus (SLE) and serum lactate dehydrogenase (LDH) was examined in 28 patients with active SLE involving only the kidney. Serum levels of total LDH, LDH1, and LDH2 were significantly higher in the patients with diffuse proliferative lupus nephritis (World Health Organization class IV) than in those with milder renal disease (classes I through III and V). Total LDH levels showed good correlations with the activity index and the total pathologic score of the renal pathologic scoring system, and with the glomerular hypercellularity and overall deposits. The elevated level of LDH was mainly due to elevated levels of its isozymes LDH1 and LDH2. These results suggest that the elevation of serum LDH levels in patients with SLE reflects the renal pathologic changes due to lupus nephritis.

The Fc receptor mediated reaction, the beta-glucuronidase and the lactic dehydrogenase activities of monocytes and the serum lysozyme level were tested together with the circulating immune complex content of patients with systemic lupus erythematosus. Simultaneously with the increasing FC receptor-mediated reaction and the elevated enzyme activities of patient monocytes, the secretion of lysozyme and the immune complex content of the sera were higher than those of the controls. A positive correlation was demonstrated between the Fc receptor-mediated reaction, the beta-glucuronidase activity, the lysozyme secretion and the immune complex content of the sera. Thus, the monocytes of patients appeared to be activated by the circulating immune complexes.

The value of determination of pleural fluid glucose, pH, lactic dehydrogenase, IgG, IgA, IgM, C3, C4, anti-IgG antibody, and hydroxyproline in distinguishing between pleural effusions caused by rheumatoid arthritis (RA) and those resulting from other diseases was studied. The series comprised seven patients with RA and 115 patients with other diseases including systemic lupus erythematosus, tuberculosis, malignant disease, empyema, pneumonia, congestive heart failure, and nonspecific pleural effusion. The low glucose concentration, the low pH and the low C4 level in rheumatoid pleural effusion were the most valuable diagnostic findings. The presence of anti-IgG antibody in pleural fluid was not specific for RA. The concentration of hydroxyproline in pleural fluid and the pleural fluid-to-plasma hydroxyproline ratio were significantly higher in RA than in tuberculosis and malignant disease. The results support the view that local metabolic and immunological phenomena as well as a high turnover of collagen occur in the pleural cavity in RA.

Examination of 27 patients with systemic lupus erythematosus (SLE) before treatment showed an elevation of the serum level of lactic dehydrogenase (LDH) in 15 patients. In these patients, the LDH level fell to normal in response to corticosteroid therapy. In six of 27 patients, steroid myopathy with elevation of the LDH level developed during corticosteroid therapy. At the same time, there was no or only a slight increase in the creatine phosphokinase level, while the SGOT and aldolase levels remained normal. The elevated LDH levels gradually returned to normal as the corticosteroid dosages were reduced and the myopathic symptoms disappeared. We suggest that the measurement of LDH levels is useful for diagnosis and the subsequent treatment of patients with steroid myopathy in SLE.

We have evaluated the clinical usefulness of certain diagnostic tests in consecutive patients with pleural effusions, including 12 who had rheumatoid arthritis, nine who had systemic lupus erythematosus, and 39 who had other diseases. Effusions from patients with rheumatoid arthritis and systemic lupus erythematosus differed with respect to glucose level, lactic dehydrogenase activity, and pH. Complement levels differentiated rheumatoid from control effusions but did not segregate rheumatoid from systemic lupus erythematosus. Immune complexes were detected in all the rheumatoid pleural fluids by radioassays using monoclonal rheumatoid factor, C1q, and Raji cells. In most of the fluids, these complexes were reactive in all three assay systems and their levels higher than those found in paired serum samples. In effusions from patients with systemic lupus erythematosus, however, immune complexes were detected mainly by the Raji cell radioimmunoassay, and levels by all three assays were similar to those of paired serum samples.

Seven patients with systemic lupus erythematosus (SLE) or SLE-like disease developed thrombotic microangiopathy. Prominent features of their acute illnesses were microangiopathic hemolytic anemia (7), thrombocytopenia (7), fever (1), nervous system disease (4), and renal dysfunction (5). Laboratory data were significant for antinuclear antibody (ANA) (7), DNA (5), low C3 level (3), low C4 level (2), antiphospholipid antibody (6), schistocytes (7), and lactate dehydrogenase > 500 (7). All seven patients received treatment that initially included steroids but later included cyclophosphamide (4), plasma infusion (1), plasmapheresis (5), intravenous gamma-globulin (2), anti-platelet agents (2), or vincristine (3). Six patients improved, and one patient expired during treatment. Of the six patients who survived this complication, three expired within the year following their acute illnesses. Histology, available in two cases, showed vascular changes consistent with a microangiopathic process. We conclude that the spectrum of vascular diseases in SLE extends beyond vasculitis to include noninflammatory vascular processes that can cause equally devastating complications.

To determine feasibility of using quantitative histochemical assessment of platelet anaerobic metabolism in lupus nephritis (LN) prognostication and elucidation of its activity, the authors examined 23 SLE patients. 20 of them developed renal lesions. Anaerobic metabolism of platelets was measured according to lactate dehydrogenase levels. All the SLE patients had significantly higher levels of the enzyme than healthy controls showed. Maximal LDG activity was registered in rapidly progressive LN with thrombocytopenia. The findings support activation of platelet hemostatic component in SLE patients and valid utilization of a new quantitative histochemical technique for determination of intracellular metabolism enzymes content.
