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.

[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).
