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.

Two new cases of association between a thymoma and a lupus illness are reported. The first was a women aged 42 years in whom were discovered simultaneously systemic lupus erythematosus (SLE) and a slowly invading thymoma, the histology of which was characterized by the predominance of epithelial cells; excision of this tumour did not appear to affect the evolution of the SLE. In the second case, a patient aged 60 years suffered from SLE ten months after the removal of a benign thymoma in which there was a predominance of lymphocytes. The SLE in this patient was easily controlled for more than a year by small doses of corticoids, but resulted in death after three years when anuria was associated with meningeal signs after the cessation of corticotherapy. The comparision of the data from these cases with those from eleven other cases in which there was association between a thymoma and SLE, brought to light several interesting facts. It is rare that SLE clearly precedes the discovery of the thymoma; it usually occurs afterwards or the two are discovered almost simultaneously. Collagenosis is of importance only when it coexists with a thymoma : starting later much more often than is usual in cases of SLE. The tumours were, in all but two cases, benign thymomas of different histological types, and their removal did not apparently influence the evolution of the SLE.

Extensive serologic changes occur in systemic lupus erythematosus (SLE) which are probably secondary to unknow primary cause(s). The New Zealand hybrid mouse model most likely has a viral-induced disease and does not show many of the clinical features of the human disease. The best example of human SLE which provides a clue to etiology is the drug-induced type, particularly that due to procainamide. In these patients it is possible to study the development of serologic changes prior to the onset of clinical manifestations, and then observe regression of the clinical and serological changes on withdrawal of the medication. Although there is a rough correlation between the many serologic abnormalities and the clinical picture, enough exceptions exist, so that single tests such as serum complement, anti-DNA antibodies, per cent DNA binding, and others, cannot be used as a sine qua non for management. Care of the patient still remains a clinical problem guided by various laboratory procedures but not dependent on any one. Alkyating agents have a limited role in the treatment of lupus nephropathy and cutaneous vasculitis but azathioprine is probably of no value in SLE.

Seven hypertensive patients with idiopathic systemic lupus erythematosus were treated with hydralazine. They received a mean daily dose of 203 mg for a mean duration of 21 months. All were taking prednisone alone or in combination with azathioprine. During therapy with hydralazine, there were no new symptoms nor exacerbation of pre-existing symptoms attributable to systemic lupus. Laboratory parameters, including antinuclear antibody titers and complement levels, either improved or remained stable. The results indicate that hydralazine can be safely used in hypertensive patients with systemic lupus who are receiving concomitant immunosuppressive therapy.

DNA transcripts of infectious RNA viruses were found to be integrated in the DNA of chronically-infected tissue cultures. DNA sequences homologous to RNA of measles virus were found in tissues affected with systemic lupus erythemotosus. These data open up a new class of virus-cell interaction that may be a result of cooperation between infectious and oncogenic viruses.

Prajmalium bitartrate (Neo-Gilurytmal) was given to 19 patients, who had either runs of ventricular extrasystoles or frequent extrasystoles. The E. C. G. was continuously monitored on magnetic tape. At a dosage of 80 mg/d (20 mg every six hours) a significant reduction in ventricular extrasystoles was demonstrated on 20 separate occasions. After two hours extrasystoles decreased to 63% of the initial level. After six hours practically the full effect of the drug had been reached; the reduction in extrasystoles stabilized after 12 hours at an average of 30% of initial level. Ten hours after the last tablet had been taken the frequency of extrasystoles had risen to 57% of initial level. Comparison with procaine amide (3 g/d) in 14 patients revealed no significant difference between the two drugs. Prajmalium bitartrate was well tolerated, while three patients receiving procaine amide complained of nausea and gastrointestinal symptoms, so that treatment had to be discontinued in two. In one patient, receiving procaine amide by continuous drip, there were reversible joint pains, resembling lupus erythematodes.

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.

Eight patients with systemic lupus erythematosus (S.L.E.) have been treated with plasmapheresis. In four patients in whom immunochemical studies indicated high levels of circulating immune complexes, the removal of 5-8 litres of plasma weekly produced a striking clinical and immunochemical improvement. The four other patients, with only minor complement disturbances and no direct evidence of circulating immune complexes, could not be shown to benefit from plasmapheresis and one patient in this group died of cerebral lupus despite intensive treatment with cytotoxic drugs. It is concluded that plasmapheresis may be of value as an adjuvant to the treatment of acute S.L.E.

Serum and urine of patients with ascertained lupus erythematodes visceralis were separated by means of the polyacrylamide gel pore gradient electrophoresis on the same experimental conditions. Deviations from the normal electropherogram were found in the serum within the gamma-globulins. For the demonstration of antinuclear factors the loose body test, the LE-cell test as well as the immunofluorescence test were carried out. In the uropherogram a highly molecular protein band could be proved which did not appear in the serum. In this fraction an immune complex which developed in the area of the kidney might be in question. It is referred to the possibility of the use of the PAA-polyacrylamide gel electrophoresis for the early recognition of renal changes.

On the patients of the consulting point for rheumatic diseases of the policlinical institute of the Karl-Marx-University Leipzig analytic examinations of the course for the existence of the LE-cell factor were carried out. We used the loose-body-test after van Soeren as screening test, controlled positive test results for several times under the same experimental conditions and supplemented it by the LE-cell test after Zinkham and Conley or later on by the immune fluorescence test. All patients with positive proof of LE-cells were examined for reference signs concerning a visceral lupus erythematodes, in which cases at the beginning of the examination nobody fulfilled the criteria of the diagnosis of a visceral lupus erythematodes. We tested the constancy of the proof of the LE-cells as well as the diagnosis in the course of longer periods. Typical changes of a visceral lupus erythematodes were seen only rarely. In 2 patients the joint processes were concomitant symptoms of a chronic aggressive hepatitis. In the p.c.p. at stage II to IV with positive LE-cell factors in the first place must be thought of a proof of LE-cell factors induced by drugs. In these cases gold is of practical importance. We could confirm that in contrast to the typical active visceral lupus erythematodes in p.c.p. the antinuclear factors have only a weakly positive result and are above all inconstant.
