[The activity of superoxide dismutase and its isoenzymes in the immunocompetent cells of the peripheral blood in systemic lupus erythematosus and rheumatoid arthritis].

General activity of superoxide dismutase (SOD) and its isoenzymic spectrum in lymphocytes and neutrophils were studied in the peripheral blood from 63 SLP and 85 RA patients. A significant decline in SOD activity and qualitative shifts in SOD isoenzymic spectrum were found in both cell groups. The differences were specific for lymphocytes and neutrophils. SOD isoenzymic aberrations proved significant in minimal activity of SLP and RA and go in the same direction in both the diseases. General SOD activity and its isoenzymic composition can serve sensitive indications of immunocompetent cell function both in SLP and RA and of the need in antioxidants inclusion into combined treatment of both the diseases.

[An evaluation of the effect of the sauna on the clinical, laboratory and psychological indices in rheumatoid arthritis].

The direct effect of sauna procedures was assessed in 196 patients with rheumatoid arthritis (RA) in minimal or moderate activity stage. Three temperature and humidity regimens were tested. The optimal conditions occurred at 80 +/- 5 degrees C and relative air humidity 10-20%. Sauna produced a positive effect on locomotor system, psychoemotional status, alleviated pain. Clinico-biochemical and immunological indices of the peripheral blood underwent insignificant transient shifts.

[The possibilities for the early diagnosis of ankylosing spondylarthritis].

Soluble antigen HLA-B27 was assayed in blood serum of 30 patients afflicted with ankylosing spondyloarthritis (AS) and 25 healthy subjects having HLA-B27 (B27+) antigen in the phenotype. As compared to B27+ healthy subjects, B27+ patients with AS demonstrated a significantly higher level of soluble HLA-B27 antigen. A substance whose functional activity was found to be identical to that of soluble HLA-B27 antigen in blood serum of B27- patients with AS was discovered for the first time. It was absent from B27- healthy subjects. In addition to the identification of the fixed forms of soluble HLA-B27 antigen, the assay of this antigen in blood serum enhances the potentialities of laboratory diagnosis of AS, which plays an important role at the early disease stages.

[Still's syndrome in adults as one of the causes of fever of unknown origin].

Based on their own investigations and reported data, the authors describe the clinical and laboratory signs of Still's syndrome in adults. Special attention is paid to an analysis of the feverish syndrome. The clinical cases of Still's syndrome running its course under the mask of fever of obscure genesis for a long time are provided. The possibilities of early diagnosis of the disease are under discussion.

[The function of lymphocyte populations based on aberrations in the lactate dehydrogenase isoenzyme spectra in systemic lupus erythematosus and rheumatoid arthritis].

The data were obtained on the presence of considerable aberrations of the isoenzymic spectrum of lactate dehydrogenase in different lymphocyte populations and subpopulations. The isoenzymic shifts reflect the changes occurring in the metabolic status of the cells and are sensitive tests detecting functional deficiency of lymphocytes.

[Study of isoenzymes of lymphocyte populations during controlled immunization and in autoimmune pathology].

It has been shown that during immune system activation pronounced alterations are observed in the metabolic process course in lymphoid cells that, probably, reflect the changes in T- and B-lymphocyte functional activity, and the kinetics of intercellular relationships. The ratio of LDH1 and LDH5 fractions most differing in electrophoretic mobility has been recommended as a sign of B-system immunity activation.

[The possibilities of an individual approach to intra-articular drug administration in rheumatoid arthritis patients].

A study was made of the possibilities of an individual approach to intraarticular administration of protease inhibitors, cytostatics and orgoteine in patients with rheumatoid arthritis (RA). The activity of hyaluronidase, superoxide dismutase, the level of rheumatoid factor and the phagocyte count in synovial fluid were examined. With regard to the results of synovial fluid analysis in 67 RA patients, contrykal, orgoteine or cyclophosphamide were administered intra-articularly (based on an individual approach) in addition to corticosteroid hormones. It has been shown that with the individual approach to intraarticular drug administration the number of repeated punctures of the joints decreased by 18.8% while the amount of glucocorticosteroid hormones administered was twice as reduced.

[Treatment of Sjögren's syndrome with protease inhibitors].

The authors reported the results of therapy of 28 patients with primary and secondary Sjogren's syndrome by iv injections of protease inhibitors (contrykal and trasylol). Findings of clinical and laboratory tests showed a significant increase in salivation and lacrimation. The elimination of concomitant oral candidosis raised the efficacy of treatment of xerostomia in many patients.

[Immunopathological manifestations of systemic lupus erythematosus and their correction during long-term dispensary observation].

The time course of immunopathological symptoms of lupus erythematosus was studied in 117 patients over a period of 5 years. It was established that routine multimodality therapy while resulting in a positive time course of clinical and clinico-biochemical indices, did not ensure the normalization of immunological parameters, particularly of the T-system of immunity. Courses of theophylline and splenin therapy were added to multimodality therapy to raise therapeutic efficacy and to return to normal the status of the immune system. A regular follow-up made it possible to stabilize the disease in 82.1% of the LE patients and to preserve working capacity in 50.4% of them.

[HLA antigens in systemic lupus erythematosus patients].

A study was made of the rate of HLA system antigens in 75 patients with different clinical versions and immuno-pathological manifestations of systemic lupus erythematosus (SLE). A total of 350 normal subjects comprised the control group. During SLE, a high rate of DNW3, B8 and AI antigens was revealed. Associative relations were established between individual clinical syndromes of SLE and immuno-pathological manifestations of the disease and definite antigens of the HLA system. The results of typing HLA system antigens can be used as additional criteria of SLE diagnosis, disease prediction, and choice of adequate therapy schemes.

[Organization and development paths of the cardiology service in the Belorussian SSR].

Data providing evidence of a developed cardiological service in the Byelorussian SSR are presented. Besides the establishment of a network of in- and out-patient institutions, mass epidemiological study of the population has been started and rehabilitation centers for patients who had recovered from myocardial infarction were created. Ways for the further development of cardiological science in the republic and the prospects of widening the prevention of cardiovascular diseases are discussed.
