Antibody-dependent cell-mediated cytotoxicity mediated by peripheral blood lymphocytes was studied in patients with systemic lupus erythematosus, polyarteritis nodosa. Sjogren's syndrome, and rheumatoid arthritis. The target cells were chicken erythrocytes coated with rabbit anti-chicken erythrocyte antibody. Antibody-dependent cell-mediated cytotoxic activity was normal in Sjogren's syndrome and rheumatoid arthritis but significantly decreased (P is less than 0.001) in active systemic lupus erythematosus and in two patients with polyarteritis nodosa. A partial regeneration of antibody-dependent cell-mediated cytotoxic activity was obtained by treatment with pronase and DNase followed by overnight incubation. Sera from patients with systemic lupus erythematosus inhibited antibody-dependent cell-mediated cytotoxic activity of normal lymphocytes. The inhibitory activity was studied by specific immunoadsorption and sucrose density geadient ultracentrifugation. Removal of IgG but not IgM greatly reduced inhibition. Inhibitory factors were present in 7S and heavier fractions containing IgG. Five systemic lupus erythematosus patients were studied serially to determine if improvement in clinical status could be correlated with a decrease in serum inhibitory factors as studied by inhibition of normal antibody-dependent cell-mediated cytotoxicity. Indeed, a greater serum inhibitory capacity was found in each patient during periods of greater disease activity.

ECG changes in 49 patients with rheumatoid arthritis, 18 with ankylosing spondylitis, 47 with systemic lupus erythematosus, 17 with dermatomyositis, 21 with scleroderma and 7 with polyarteritis nodosa were compared with ECG changes in 106 control subjects. The classification of ECG findings was based mainly on the Minnesota Code. Compared with control subjects, pathological Q--QS, ST segment and T wave patterns were more common in all patient groups--including dermatomyositis, in which cardiac involvement has rarely been reported. P terminal force (PTF) was higher in the patient group. Conduction defects were probably more common in connective tissue diseases, whereas differences in ectopic beats, arrhythmias, QRS duration and QRS axis and R wave amplitude were not significant. The only significant difference between the steroid-treated patients and those without such treatment was the higher frequency of ST changes in the steroid-treated group. The results imply that heart affection is common in all connective tissue diseases. The several mechanisms underlying the cardiac involvement are reflected in many ways in the electrocardiograms of these patients, including an increased frequency of ECG changes mimicking those met in coronary heart disease.

Morphological changes in the pulmonary artery and its major branches were studied histologically and histochemically on autopsy cases of polyarteritis nodosa (23), systemic lupus erythematosus (10), systemic scleroderma (12), and rheumatoid arthritis (5). The ages of the fatalities ranged from 9 months to 77 years. An identical type of lesions was revealed: disorders of the connective tissue, destruction of elastic fibers, alterations of vasa vasorum, with cellular reactions typical of each nosological form reflecting the peculiarities of the immunological processes. The initial stage in the genesis of lesions in the vascular walls of the major pulmonary arteries is the involvement of vasa vasorum as a regular disorder of the microcirculatory ways in all collagen diseases.

Rheumatoid arthritis is a multisystem disease, with many clinical forms bearing close resemblance to systemic lupus erythematosus, dermatomyositis or polyarteritis nodosa. Although the involvement of the integument is not as disabiling as the joint disease, the extent of disability may be of sufficient magnitude to necessitate therapeutic intervention. Two patients are presented whose skin involvement was suggestive of cutaneous angiitis and who responded dramatically to treatment using sulfasalazine.

The data from the literature and the authors' own studies on changes in the lungs in systemic diseases of the connective tissue with immune disorders: systemic lupus erythematosus, progressive systemic sclerosis, rheumatoid arthritis, and periarteriitis nodosum are presented. Changes in the lungs in the above diseases have some common features: damage of the microcirculatory bed, increased vascular permeability, impregnation with plasma of alveolar septae and vessel walls, cellular reactions, and septo-alveolar sclerosis. Specific features of each of the diseases under study were demonstrated. The time course of morphological changes in the lungs was followed in relation to the severity, duration, and form of the disease.

Although thymosin, a thymic hormone, has been shown to restore cellular immunity in NZB/NZW mice, its effect in human systemic lupus erythematosus (S.L.E.) and other auto-immune disorders has not been tested. The present study shows for the first time that the proportion of "null cells" in peripheral-blood lymphocytes of patients with active S.L.E. is significantly decreased after in-vitro thymosin treatment. Thymosin has no effect on the percentages of T cells, B cells, and "null" cells in peripheral-blood lymphocytes from normal controls and patients with inactive S.L.E. and active rheumatoid arthritis. These findings suggest that thymosin may play an important part in the pathogenesis and treatment of this condition.

Antibody activity against mumps, measles, polio, and rubella viruses was determined in patients with juvenile rheumatoid arthritis (J.R.A.), rubella-vaccine associated arthritis, adult rheumatoid arthritis, other chronic systemic disorders (e.g., systemic lupus and dermatomyositis), and in a matched population of normal, non-rheumatoid (control) children. The antibody levels against mumps, measles, and poliovirus were similar in all patients. Rubella-antibody levels in rheumatoid arthritis and other systemic disorders were similar to those observed in controls. The mean rubella-antibody levels in rubella-vaccine arthritis were 4 times higher than in controls. The IgM and IgG rubella-antibody levels in J.R.A. were found to be 4-6 times higher when compared to titres observed in the controls. Highest antibody levels were seen in younger children with J.R.A. Detection of rubella-virus antigen was attempted by immunofluorescence in the sediment smears of synovial fluid of patients with J.R.A., adult rheumatoid arthritis, and other non-rheumatoid joint diseases. Specific staining for rubella virus antigen was observed in the synovial fluid of 33 percent of patients with J.R.A. No antigen was detected in the synovial fluid from other patients. These observations suggest a possible role of rubella-virus infection in J.R.A.

Titers and patterns of antinuclear antibodies (ANA) in sera from 134 normal blood donors, 20 patients with rheumatoid arthritis, 15 patients with systemic scleroderma, and 32 patients with diagnosed or suspected systemic lupus erythematosus (SLE) were studied. The difference between the findings with sera of patients with SLE and normal subjects in terms of high (greater than 160) titers of ANA was greater than in terms of peripheral staining patterns. However, in comparing sera from patients with SLE with sera from patients with other connective tissue diseases, greater differences were found in the incidence of peripheral patterns of ANA compared to differences in the frequency of high ANA titers. Maximum specificity in the diagnosis of SLE was achieved when both titers and patterns of ANA were considered.

Sixty-eight determinations of leukocyte chemotaxis were performed in 42 patients suffering from systemic lupus erythematodes (17 cases), rheumatoid arthritis (15 cases) and scleroderma (10 cases). In contrast to the results of others, this study showed a deficiency in only 15 of 42 cases (35.7%). Impairment of chemotaxis was always transitory and demonstrable only during acute phases of disease. Intrinsic deficiency of PMN leukocytes as well as deficiency of plasma factors were related to the clinical and biological course of the disease and to the treatment.

In a young girl, aged 17 years, there occurred, 9 months after starting treatment with isoniazid and rifampicin, clinical signs of rheumatoid arthritis with facial erythema of vespertilio type. The presence of L.E. cells and antinuclear antibodies with a high titer, the rapid disappearance of all the clinical signs on stopping isoniazid, and the transient exacerbation of the syndrome on giving a single dose of isoniazid, gave the diagnosis of systemic lupus erythematosus induced by isoniazid. 18 months after stopping the drug, the patient is apparently cured, but there persists in the serum antinuclear antibodies in low concentration (1/200). A study of acetylation of isoniazid in this patient and her 3 sisters, showed that they were all of the slow acetylating phenotype. The late prognosis of this disease and the physiopathological value of the slow acetyl phenotype are worth discussion.
