[Correction of microcirculatory disorders in rheumatic diseases].

The present article is concerned with the problems of pharmacotherapy of microcirculatory disorders (MD) in rheumatic diseases (RD) and with the complex of methods permitting one to judge the intensity of the pathological process at the microcirculatory level. Based on the study of the problems of the correction of MD in more than 300 patients with RD the vasospastic, ischemic, cutaneotrophic, renal and pulmorenal syndromes as well as the DIC syndrome were recognized which require the correction therapy. Differentiated therapy including heparin, deaggregating agents, rheopolyglucin and peripheral vasodilators should be performed with regard to the degree of blood rheological properties derangement and tendency of alterations in the hemostatic potential. To evaluate the treatment, efficacy, biomicroscopy of the vessels of the eyeball conjunctiva and laboratory standardized methods for hemostasis study are the most available techniques.

[Cytotoxic antibodies to thymocyte antigens in rheumatism and other diseases].

Cytotoxic antibodies reacting with mouse and human thymocytes were detected in rheumatic patients' sera. The level of cytotoxic antibodies was considerably higher in active than in inactive process. A correlation was found between the antibody level and the clinical course of rheumatic fever. The cytotoxic index was the highest in sera of patients with acute rheumatic fever. Thymocytotoxic antibodies were also found in other autoimmune diseases. In sera of normal individuals, antibodies to thymocytes were revealed rarely and in small quantities. A possible role of thymocytotoxic antibodies as a cause of deficit of T suppressors in autoimmune diseases is discussed.

[Corinfar in the treatment of Raynaud's syndrome in systemic scleroderma (preliminary results)].

Twenty patients with systemic scleroderma (SSD) and Raynaud's syndrome (RS) received 30-80 mg of corinfar, a blocker of calcium channels, during 14 days. Seventeen patients responded to the treatment. The clinical effect was manifested by a decrease in the rate, duration and intensity of RS attacks. Side effects were recorded in 6 patients, but the drug was discontinued only in 2 patients because of the allergic reactions. During treatment, the patients showed an increase in tissue blood flow parameters. Corinfar may be regarded a drug of choice in the treatment of marked RS in SSD.

[Clinico-morphological characteristics and working classification of kidney diseases in patients with systemic scleroderma].

Based on a study of 110 patients with systemic scleroderma (SSD) (74 had involved and 36 uninvolved kidneys) the authors provide the clinico-functional and morphological characteristics of renal lesions and the working classification of sclerodermic nephropathy (SN). The two basic variants of SN were recognized: acute and chronic. The latter one was subdivided into clinical, moderate and pronounced SN. A correlation was revealed between the functional (glomerular filtration lowering) and ultrastructural (reticulation of endotheliocytes and thickening of the basal membrane of the glomerular capillaries) signs evidencing derangement of the microcirculatory bed. Morphological examination of the kidneys disclosed alterations that mirror the complex pathogenesis of SSD: derangement of the microcirculatory bed, immunopathological disorders, activation of connective tissue components.

Cyclic nucleotides and calcium transport in cultured dermal fibroblasts from progressive systemic sclerosis and rheumatoid arthritis patients.

Levels of cAMP were decreased and cGMP increased in progressive systemic sclerosis (PSS) fibroblasts compared with normal fibroblasts. PSS cells took up unusually large quantities of Ca++. The epinephrine-induced increases in cAMP were diminished sixfold and epinephrine-induced Ca++ uptake was abnormal in PSS cells. Considerable heterogeneity was observed in rheumatoid arthritis fibroblasts. Membrane-bound abnormalities in (PSS) cells may be of importance in the defective control of collagen production in progressive systemic sclerosis.
