[Bishofit in the treatment of rheumatoid arthritis].

AIM: To evaluate effectiveness of a natural mineral bishofit in combined treatment of rheumatoid arthritis (RA). MATERIAL AND METHODS: The study included 71 RA patients with minimal activity of the pathological process and articular disorders of stage II. Bishofit was used in baths and compresses. 33 AR patients of group 1 took bishofit baths (14 procedures) and non-steroid anti-inflammatory drugs (NSAID), 27 RA patients of group 2 were treated with bishofit compresses (14 procesures) and NSAID, 11 patients of group 3 (controls) received NSAID alone. The effect of the treatment was assessed on the basis of clinical data, the length of the affected joint circumference, antitryptic blood activity, activity of malate dehydrogenase, lactate dehydrogenase isoenzymes, plasmin, plasminogen, ESR, sialic acids. RESULTS: Bishofit-treated patients showed earlier (by 5-6 days) and greater (by 25-35%) decrease of the pain, joint and inflammatory indices as well as duration of morning stiffness, length of the affected joint circumference and joint mobility, improvement of the tests' results. A response and an appreciable response to combined therapy with bishofit were achieved in 62.9-63.6% of cases vs 45.5% in the control group. Bishofit baths and compresses did not differ considerably by therapeutic efficacy.

[Use of affinity interaction of biologically active substances in practice of public health system].

AIM: To determine the potentialities of use of affinity interaction of immobilized biologically active substances (bacterial cells or their fragments, toxins, antigens of various chemical nature, immunoglobulins, enzymes, gangliosides, etc.) for medical practice. MATERIALS AND METHODS: Emulsion polymerization of acrylamide monomers in the gaseous nitrogen current was used as a basic method for preparation of solid-phase magnetic immunosorbents (MIC). A procedure for preparation of siliceous MIC was also applied. The prepared MICs were used a solid phase in enzyme immunoassay and immunofluorescence assay and the recorded data were compared with those of studied conventionally used in practical medicine. RESULTS: The use of MIC made it possible to detect pathogens of particularly dangerous infections in large volumes of the samples contaminated with another microflora. With the proposed MIC, one can stand a good chance of surveying large contingents of the population, of obtaining the quantitative results in shorter periods to establish a diagnosis. With this, the sensitivity and specificity of immunoassays substantially increase. Whether MIC may be used as selective hemosorbents to remove specific antibodies from the blood of patients with rheumatic diseases for therapeutic purposes was studied. CONCLUSION: The findings are indicative of wide potentialities of use of affinity interaction of biologically active substances immobilized on inert carriers with the inserted magnetic material in the laboratory diagnosis of diseases of both infectious and autoimmune nature, which may be widely used in the in- and outpatient settings.

[Affinity sorbents having magnetic properties in the clinical picture and diagnosis of communicable and non-communicable diseases].

Affine magnetic sorbents which have no analogs in the practice of our country have been for the first time developed for the rapid diagnosis of various life-threatening diseases (plague, cholera, anthrax, glanders, meliodosis, tularemia, leptospirosis, dysentery, viral hepatitis A) and for the identification of their causative agents. The efficacy of new magnet-controlling test systems has been repeatedly confirmed by their applications in epidemiological events and emergencies: in the epidemiological surveillance of viral hepatitis A in Stavropol and in the Caucasian Mineralnye Vody towns, Stavropol Territory (1994), in the identification of cholera patients, in the detection of transmission factors, when monitoring during large epidemic out-bursts of cholera in Stavropol (1990), Daghestan (1994), as well as in the microbiological monitoring during military conflicts in the Chechen Republic (1995). The application of the sorbents has shown that their sensitivity is 4-5 times as much as that of conventional serological assays. In addition, biotechnologies for the production of polyacrylamide and composite aluminosilicate affine immunosorbents with magnetic properties have been developed. They have been used as the basis for designing immobilized granulated antigen reagents for the immunodiagnosis, differential diagnosis, evaluation of the time course and severity of a disease, the efficiency of therapy in patients with systemic scleroderma, proliferative arthritis, systemic lupus erythematosus, juvenile rheumatoid arthritis, osteochondrosis.

[Use of magnetosorbents in the immunodiagnosis and therapy of systemic lupus erythematosus and rheumatoid arthritis].

The authors present new technology of producing immobilized granulated antigenic magnetosorbents (MS) using collagen type II, IgG, denaturated DNA and cardiolipin which were employed in enzyme immunoassay for detection of specific antibodies in the blood of patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Due to high capacity, MS demonstrated effectiveness in early diagnosis, prognosis of RA and SLE as well as in control over the treatment effects. As shown in in vitro experiments, MS have high selective capacity and atraumaticity for blood corpuscles. MS can be sterilized, regenerated and reused which is a great advantage.

[Purine metabolism enzymes in diagnosis and differential diagnosis of osteoarthritis and gout arthritis].

AIM: To characterize purine metabolism in osteoarthritis (OA) and gout arthritis (GA) diagnosis and differential diagnosis of these diseases. MATERIALS AND METHODS: We estimated xanthine oxidase (XA), xanthine dehydrogenase (XDG), 5'-nucleotidase (5'-NT) activity, esoenzymes of XDG and content of uric acid (UA) in the sera of 44 patients with osteoarthritis and 34 patients with gout arthritis. RESULTS: Hyperuricemia was revealed in 25 percent of patients with osteoarthritis, in 64.7 percent of patients with gout arthritis. XO, XDG, 5'NT activity, XO/XDG activities ratio, XDG-2 esoenzymes and content of UA were increased in OA patients compared to healthy controls. XO, XDG activity, XDG-2 esoenzymes and UA content in GA patients were higher than those in OA patients. CONCLUSION: The enzyme difference found may promote differential diagnosis of OA and GA. The enzyme indices essentially depend on clinical specificity of the disease and can be helpful in the assessment of the treatment efficiency.

[Efficacy of D-penicillamine and methotrexate in the treatment of rheumatoid arthritis in relation to levels of circulating rheumatoid factors of different classes].

AIM: To optimize treatment for rheumatoid arthritis (RA) and to define indications for D-penicillamine and methotrexate therapies on an individual basis by taking into account the levels of rheumatoid factor (RF) isotopes circulating in blood. MATERIALS AND METHODS: A total of 105 patients (mean age 46.39 +/- 1.35 years) with varying RA were observed. Indirect solid-phase enzyme immunoassay was used to analyze RF isotopes; the pattern of the disease and the efficiency of therapy for RA were compared with the patients' immunity. RESULTS: With elevated RF IgG levels, the cardiovascular system, thyroid, mucous membranes were found to be more frequently impaired and vasculitis was diagnosed. CONCLUSION: The use of cuprenil and methotrexate in RA substantially improves patients' immunity.

[Immobilized antigenic preparations with magnetic properties in the diagnosis and treatment of rheumatic diseases].

A procedure was first developed to prepare the immobilized granulated antigen agents (IGAA) based on collagens of types I, II, III, IgG, native DNA, RNA, cardiolipin, superoxide dismutase, and glutathione reductase. The agents were applied to both immunofluorescence and enzyme immunoassay to identify specific antibodies. IGAA were effective in early diagnosis, prognosis, and control of therapy for systemic lupus erythematosus, systemic sclerosis, rheumatoid arthritis due to their high capacity. These antigen agents were used in vitro and in vivo in hyperimmune laboratory animals as magnetic sorbents and exhibited high capacities and low traumatic properties for blood cells. IGAA may be regenerated, sterilized, and reused.

[The relation between the level of antibodies to the glycosaminoglycans of the cartilage in patients with osteoarthritis and the efficacy of treatment with chondroprotectors].

AIM: To improve the efficacy of osteoarthrosis (AO) treatment by chondroprotectors by defining individual indications for their use, based on the initial level of antibodies to cartilaginous glycosaminoglycans (GAG) in the blood serum. MATERIALS AND METHODS: Anti-GAG were detected by indirect solid-phase enzyme immunoassay. The antigen was a sulfated GAG preparation GAG-polysulfate (arteparon) manufactured by Luitpold-Werk (Germany). Sera of 110 OA patients were tested. Fifty of them were treated by rumalon, 20 with arteparon, and protocols of 40 patients included no chondroprotectors. RESULTS: The highest levels of anti-GAG were found in OA patients with multiple involvement of the joints, rapidly progressing disease, and secondary synovitis. The titer of antibodies increases with disease duration and in patients with the roentgenological stage of OA, reaching the maximum by 10-15 years of disease or by stage III. Efficacy of chondroprotectors was lower at lower levels of antibodies to cartilaginous GAG. CONCLUSION: Chondroprotector therapy of patients with initially high levels of antibodies to GAG is unadvisable, for it can lead to exacerbations, specifically, to secondary synovitis.

[Antibodies to skeletal muscle myofibrillar proteins in the diagnosis of rheumatoid arthritis].

One of the mechanisms of muscular involvement in RA patients was elucidated by identification of antibodies to skeletal muscle components (actin and tropomyosin). Clinical symptoms of skeletal muscles involvement in RA proved to be associated with elevated count of tropomyosin antibodies against an insignificant informative value of actin. Enzyme immunoassay with tropomyosin has established a direct correlation between the number of the antibodies and RA activity.

[Metabolism of articular cartilage in the presence of interleukin-I alpha, its inhibitor and blood serum].

The study was made of the effect which interleukin receptor antagonist protein (IRAP) and bovine serum have on interleukin-1 alpha (IL1a) activity in cartilage culture of young bulls. It was established that IL1a leads to cartilage degradation as shown by an increase of sulphated glycosaminoglycans (sGAG) in culture medium and their decrease in tissue, inhibition of proteoglycan (PG) synthesis by chondrocytes. This effect of IL1a is suppressed by IRAP. In serum-free culture the cartilage tissue produced proteoglycans in much less quantities. In these conditions IL1a stimulated chondrocytes, cytokine did not respond to IRAP.

[Immobilized granulated drugs with magnetic properties based on nDNA, RNA, cardiolipin in the diagnosis and treatment of systemic lupus erythematosus].

To advance diagnosis and treatment of systemic lupus erythematosus (SLE), the authors have developed a number of specific diagnostic preparations basing on nDNA, RNA, cardiolipin immobilized into the three-dimensional lattice of polyacrylamide gel. Using such granulated antigenic preparations with magnetic properties, a correlation has been derived between SLE activity, visceral pathology and a level of specific antibodies. In view of a successful experimental use of the preparations as selective sorbents, they may be introduced into extracorporeal treatment. Immobilized granulated preparations can be used in immunofluorescent tests and enzyme immunoassays.

[The properties and areas of use of an immobilized granulated streptolysin O].

The heat-resistant preparations of immobilized granulated streptolysin O were obtained with the use of emulsion polymerization techniques. In experiments the presence of gangliosides and cholesterol affected the hemolytic activity of immobilized streptolysine O. The preparations thus obtained were used in the enzyme-linked immunosorbent assay as antigens for the determination of specific antibodies in rheumatic fever patients and healthy persons.

[Bischofite in the treatment of patients with osteoarthrosis deformans].

Bishofit baths and compresses on affected joints were added to combined treatment of 43 patients with dystrophic metabolic arthritis (DMA). Twenty control DMA subjects received. nonsteroid antiflammatory drugs without bishofit. Comparison of the two groups demonstrated that adjuvant bishofit promoted more rapid clinical remission of DMA. The baths versus compresses yielded essentially similar results.

[The clinico-diagnostic significance of determining creatine kinase activity and isoenzymes in patients with systemic lupus erythematosus].

Creatine kinase (CK) activity was assessed in the direct and reverse tests and CK isoenzymes in agar gel for 41 patients with systemic lupus erythematosus (SLE). With growing activity of the process, there was a decline of CK activity in the reverse test though in the direct test this activity was scarcely changeable allowing a shift to predominance of the direct response. Significant differences were found in CK reverse reaction which correlated with SLE activity and pattern. The more active the disease, the less content of CK-1 and CK-3 isoenzymes. Investigations of CK activity and isoenzymes during SLE treatment help objectivize the clinical control.
