The serum of a female suffering from Lupus erythematosus visceralis was investigated by complement fixation for the reaction with native and denatured DNA's of various base composition. The reaction with native DNA is independent on the (G+C)-content of the DNA. It is apparent that the responsible antibodies react with determinants of the helical conformation, which are identical in the various DNA-molecules. Quantitative differences are found with denatured DNA's. The strongest complement fixation is observed with (G+C)-rich denatured DNA. The reaction with denatured DNA is only partially inhibited by DNA digest. These antibodies obviously react with sequential determinants containing bases. Therefore, they are induced by a different mechanism of sensitization.

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.

A patient with systemic lupus erythematosus of long duration developed secondary amyloidosis and finally died after the additional complication of malignant lymphoproliferative disease. Multiple system involvement, typical serologic findings, and postmortem evidence substantiated the diagnosis of lupus erythematosus. Amyloid deposition was found in several organs, but was notably extensive in the adrenal cortex. This extensive deposition resulted in adrenal insufficiency, which was diagnosed clinically and treated until the patient's death from lymphoma. The particular nature of the malignant lymphoma is emphasized; a distinctive feature was the disappearance of positive lupus erythematosus cells from the buffy coat and the reduction in titers of relevant serologic tests toward the end of the illness. In spite of this reduction, many hematoxylin bodies and abundant complete lupus erythematosus cells were found in the lungs on postmortem examination.

Two commercially available lupus erythematosus (LE) latex tests were compared against positive antinuclear antibody (ANF) sera of known titers. The Lederle SLE Latex Test Kit was found to be more specific and relatively more sensitive, particulary with high ANF titers, than the Hyland LE Test Kit. The latex test is a rapid, simple method which, when positive, can be suggestive of systemic lupus erythematosus (SLE) or other collagen disease. However, at present this test cannot replace the immunofluorescence method for detecting ANF. Where there is any clinical suggestion of SLE or a related condition, all negative results should be tested by immunofluorescence methods.

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.

The cases of 20 patients, each of whom has a positive lupus erythematosus cell preparation and a negative antinuclear factor test, are presented. The concept of a false-positive lupus erythematosus preparation is suggested. Five common mechanisms causing a false-negative antinuclear factor test are discussed and evaluated. Clinical material from the 20 patients is described and pitfalls in diagnosing systemic lupus erythematosus are reviewed.

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.

Immunodiffusion studies have been made on the plasma of 9 species (Vulpes vulpes, V. corsak, Alopex lagopus, Canis aureus, C. lupus, C. familiaris, C. dingo, Nyctereutes procynoides, Fennecus zerde) from the family of Canidae using milk antisera. Unlike rabbit antisera used earlier, milk antisera make it possible to detect more significant antigenic divergency with respect to 5 alpha- and beta-globulins. These globulins seem to have a higher evolution rate of antigenic mosaics as compared to other plasma proteins in the family investigated. The family Canidae serologically may be divided into two main groups: 1) the genus Canis which includes the wolf, domestic dog, dingo, jackal and 2) species which significantly differ from the former (the fox, polar fox, dog fox, fennec). In relation to these two groups, the raccoon dog occupies special position.
