In special designed vials using coverslides glued to segments of polyethilene test tubes of 0.15 ml of fibrin free blood were incubated during 45 min to 37 degrees C in a humid chamber. Blood samples were obtained from patients with disseminated Lupus erythematosus (DLE) and normal subjects (N). Adhered polymorpho-nuclear cells (PNC) to glass were washed with Hank's solution; immediately 0.15 ml of DLE or N serum containing 5X10(6) lymphocytes (L) were added to culture cells and incubated at 37 degrees C during 30 min. Lymphocytes were previously incubated at 37 degrees C during 30 min with either N serum or DLE serum. Thereafter the segment of polyethilene test tube was detached from coverslides and cells attached to glass was washed with Hank's solution and stained with Wright solution. PMN of DLE and N in presence of L of DLE and N incubated with fresh serum of DLE formed 5 to 15% of LE cells. Determining factor for LE cells formation is the serum of DLE. Slides contained only PMN and LE cells which make easy the observation of results. All possible combinations with PMN and DLE serum and N serum allowed inclusion of several negative or positive control groups.

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.

Fifteen patients with epidermal nuclear staining on direct immunofluorescence of normal skin and high titer serum antibody to ribonuclease-sensitive extractable nuclear antigen (ENA) had diffuse nonscarring and focal alopecia, abnormal pigmentation, swollen hands with sclerodactyly, and chronic cutaneous lupus erythematosus (LE) as the most common dermatologic features. Direct immunofluorescence of normal, unexposed skin revealed a particulate ('speckled') epidermal nuclear staining pattern in all 15 patients and subepidermal immunoglobulin deposits in 5. Ribonucleoprotein antibodies in high titer are associated with this characteristic type of epidermal nuclear staining. These findings provide easily detectable markers for a less aggressive subset of LE characterized by distinctive clinical and laboratory features consistent with mixed connective tissue disease.

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.

A 63-year-old man developed an asymptomatic pleural effusion following the administration of 500 gm of procainamide hydrochloride over a six-month period. The diagnosis was initially suggested by the finding of lupus erythematosus cells in the pleural fluid. Lupus erythematosus cells and antinuclear antibodies appeared in the blood two months later and remained for a period of six months. The diagnosis was corroborated by the presence of antibodies to denatured DNA, but not to native DNA.

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.

Systemic lupus erythematosus (SLE) is not a rare disease. There are several common clinical signs which should alert the physician to a possible diagnosis of SLE and which should condition him to look for specific clinical and laboratory findings. In addition to simple screening tests, useful procedures include a search for antinuclear antibodies, lupus erythematosus (LE) cells, anti-DNA antibodies and low serum complement. Management is determined by the type of course encountered but most patients will do well under the care of their family physician.
