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.

Lupus erythematosus (LE) cells were demonstrated inpleural fluids from two patients with systemic lupus erythematosus (SLE). They were observed in preparations stained with the Giemsa and the Papanicolaou stains. The finding of LE cells in serous fluid has rarely been reported. Our results suggest that it is imporant to search for LE cells in serous fluid in patients in whom the diagnosis of SLE has not been established.

Cold-reactive antibodies cytotoxic for peripheral monocytes from more than half of normal donors were found in the sera of 2 of 25 patients with systemic lupus erythematosus (SLE) and 1 of 26 with rheumatoid arthritis (RA), and they were absent in 25 normal sera. In contrast, lymphocytotoxic activity for T or B lymphocytes was found in over half of the lupus sera. The antibodies to monocytes were primarily IgM and exhibited varying specificities. Some of the antibodies were directed against antigenic determinants common to monocytes, T and B cells, or against determinants shared between monocytes and one lymphocyte type. One serum possessed a high titer of antibodies that were specific for monocytes. The clinical significance of antimonocyte antibodies remains to be established.

Main components of kinin system, the arginine-esterase activity and proteinase inhibitors were estimated in blood serum of patients with nephrotic syndrome of various etiology (glomerulonephritis, amyloidosis, systemic lupus erythematous) and also in patients with latent nephritis and in healthy donors. Content of all the kinin system components (kallikreinogen, kininogen and kininase 1) proved to be increased in all the forms of nephropathy studied. Free kallikrein was found in blood serum of patients with nephrotic syndrome as distinct from healthy persons and patients with latent nephritis. The arginine-esterase activity, which shows the level of trypsin-like proteinases, was altered dissimilarly, depending on the nephrotic syndrome etiology: it was maximally increased in nephrotic syndrome of amyloid genesis and decreased in patient with systemic lupus erythematosus. High content of kallikrein and kininase I with simultaneous decrease in kininogen was typical for patients with severe form of nephrotic syndrome. Impairment of kidney in nephrotic syndrome was also characterized by an increase in alpha1-antitrypsin and in the total antitryptic activity, which reached the maximal value in nephrotic syndrome of the I degree and decreased at the II degree of the disease. In nephrotic syndrome content of alpha2-macroglobulin was maximally increased at the II degree of nephrotic syndrome and decreased in severe form of the disease. The primary alteration in content of proteinase inhibitors and high level of kinin system components were assumed to determine the conditions for activation of kinin system in blood serum and to impair the nephrotic syndrome pathogenesis, which was complicated by systemic manifestations. High content of kinin system components was apparently determined by the increased synthesis in liver tissue in response to inflammation and massive proteinuria; kininase I and alpha2-macrolgobulin, as proteins with high molecular weight, were likely to be selectively retained in blood circulation when the capillary penetration was increased.

Analysis is carried out of the clinical, pathomorphological and immunological characteristic of lupus nephropathy in 62 patients, 56 females and 6 males. A series of new investigation methods were used for that purpose. An early tendency towards kidney involvement in the course of LED is established and in 22 of the patients (36%) the renal symptoms have been the first clinical manifestations of the basic illness. Lupus nephropathy progresses most often with a nephrosis syndrome (in 66.1% of the patients), rarely pure and not combined with hypertension and/or with renal insufficiency. The pathomorphological changes are rather multiform but in the majority of the cases almost all structural elements of glomerules and the rest of the renal tissue are affected. The clinical picture severity, histopathological changes and nephropathy evolution course were established to be distinctly dependent on the course acuteness of the basic morbid process. The importance of the detailed study of the clinico-morphological and immune characteristic of lupus nephropathy upon the timely diagnosis. Proper treatment and the prognosis assessment of the illness is stressed upon.

Treatment of 16 SLE patients with levamisole resulted in significant reduction of a variety of clinical parameters of the disease. Clinical improvement was both subjective and objective. Thus, levamisole may represent a possible alternative or adjunctive approach to SLE therapy. Although proper assessment of its actual quantitative importance in the treatment of Lupus must await large scale studies under double-blind conditions, nevertheless, these preliminary results are very encouraging.

The specific binding of antigens by antibodies leads to the development of antigen-antibody-complexes. Apart from the connected with this and desirable immunological protection immune complexes, however, may also have an pathogenic effect on certain conditions (e. g. transmission of the capacity of phagocytosis), depositing themselves in the vascular regions concerned, activating complement and after binding to cell membranes causing the release of unspecific mediators. Finally these lead through increased vascular permeability, local ischaemia and hyperaemia, respectively, and the release of proteolytic enzymes to a lesion of the tissues. In a series of in most cases chronic inflammatory diseases depositions of immune complexes may be proved in the tissues concerned. However, it is difficult to establish exactly in the individual case, whether they considerably participated in the development of the clinical picture. By analogies to experimentally produced immune complex diseases at least some entities of diseases (e. g. lupus erythematodes disseminatus) or defined local alterations of the tissues (e. g. glomerulonephritis of immune complex type) may be defined pathogenetically.
