Features of the immunological profile of blood and urine in patients with post-infectious glomerulonephritis.

The timely diagnosis and treatment of post-infectious glomerulonephritis (PIGN) is currently limited by the erased and low-symptom nature of the disease, which leads to the search for informative biological markers of the disease, which can be used as immunological indicators of blood and urine. The study was carried out in order to establish the characteristic changes in the immunological parameters of blood and urine in patients with PIGN. The study included 60 patients with PIGN from among the patients, hospitalized in the nephrology department of the Republican Clinical Hospital of Health Care Ministry of the Chuvash Republic in 2015-2018.

[About connection of clinical manifestations of glomerulonephritis with features of the thyroid status of patients].

Background: There are four clinical variants of glomerulonephritis (GN) - urinary (latent), hypertensive, nephrotic and mixed. It was found that the features of clinical manifestations of GN that determine its clinical variant do not depend on the etiology, pathogenesis and morphological form of the disease. Taking into account the obtained data on the association of nephrotic syndrome with hypofunction of the thyroid gland, we suggested, that the formation of clinical variants of GN may be influenced by the features of the thyroid status of patients.

[Determining of cytokine levels in the urine in clinical practice.].

The paper presents data on the study of the content of cytokines (IL-1β, RAIL-1β, IL-2, IL-4, IL-10, IL-17A, TNF-, IFN-γ) in the morning urine using enzyme immunoassay in healthy individuals (n = 20) and in patients with acute glomerulonephritis (n = 93). The determination of cytokine levels in patients was carried out in the debut of the disease and 12 months after the onset of the disease. The obtained indicators of cytokine content in the urine are presented as absolute values in pg/ml and creatinine-normalized values calculated by the formula: cytokine level (pg/ml) / urine creatinine (µmol/ml).

[The study of HLA-associations of chronic obstructive disease of lungs in conditions of organic-silicon manufacture].

The purpose of study is to examine associations of polymorphic allele genes HLA class II - DRB1, DQA1 and DQB1 and their haplotypic combinations with chronic obstructive disease of lungs in workers of organocilicic manufacture in Chuvash population. The HLA-genotyping was implemented to 50 patients with chronic obstructive disease of lungs and 38 healthy workers of organocilicic manufacture, belonging to Chuvash ethnic population. The genotyping was implemented on three genes HLA: DRB1 (14 alleles), DQA1 (8 alleles) and DQB1 (11 alleles) using multi-primary polymerase chain reaction technique.

The role of circulating cytokines and thyroid hormones in the development of the nephrotic variant of glomerulonephritis.

Unlabelled: The purpose of the research - studying the features of the production of pro- and anti-inflammatory cytokines, as well as indicators of thyroid status in patients with nephrotic variant of glomerulonephritis (GN). Research methods.

Methods: The examination involved 78 patients with primary GN, including 30 patients with nephrotic syndrome (NS) and 48 GN patients who had no NS symptoms.

[THE CHARACTERISTICS OF CYTOKINE STATUS UNDER DIFFERENT CLINICAL VARIANTS OF GLOMERULONEPHRITIS].

The article presents results of identification of indicators of cytokine status in 58 patients with glomerulonephritis using solid-phase immunoenzyme analysis. It is established that in patients with glomerulonephritis the level of pro-inflammatory and anti-inflammatory cytokines (IL-lβ, IL-2, IL-10 and Ra-IL-1β) circulating in blood is augmented. The differences are established concerning cytokine status of patients depending on clinical type of disease.

[Laboratory manifestations of asymptomatic zinc deficiency].

The aim of the present investigation was to study the laboratory manifestations of asymptomatic zinc deficiency caused by the geochemical conditions of the biosphere, such as decreases in the soil levels of zinc ( > 0.1 mg/kg) and its dietary intake to 9.1 +/- 0.

[The clinical and immunological manifestations of infiltrative pulmonary tuberculosis under natural zinc deficiency].

Patients with infiltrative pulmonary tuberculosis who lived in zinc-deficient areas (the level of mobile zinc in the soil is < 0.1 mg/kg, and its dietary level is 9.1 mg/day) were found to have a significant depression of the T-cell link of the immunity system along with enhanced activation apoptosis and decreased phagocytic activity of neutrophils.

Localization of the gene responsible for familial benign polycythemia to chromosome 11q23.

Familial benign polycythemia (FBP) (OMIM 263400) is a rare autosomal recessive condition characterized by erythrocytosis, normal leukocyte and platelet counts, normal uric acid level, and usually increased erythropoietin production. There is a high incidence of this disorder in Chuvashia (Russian Federation), probably due to a founder effect. In an attempt to locate the gene responsible for this disorder, we have carried out linkage studies in 12 Chuvash families, with 35 affected and 32 unaffected members.
