BackgroundNephrotic syndrome (NS) is accompanied by a risk of thrombotic complications due to hypercoagulability. Routine laboratory tests are not sensitive enough to detect these disorders, and therefore the use of integral coagulation tests, including a new thrombodynamic test (TT) in patients with NS, is of high relevance.AimUsing a TT to determine hemostasis disorders in patients with chronic glomerulonephritis (CGN) with NS.Materials And MethodsThe study included 49 patients with CGN, mean age 37 years, of which 25 (51%) women and 24 (49%) men. Of all the examined patients, 20 (40.8%) of people had NS, 29 (59.2%) had no NS. The process of clot formation was assessed by TT.ResultsAccording to TT, 30% (6/20) of patients with NS and 13.7% (4/29) of patients without NS have hypercoagulation with changes in parameters that go beyond the reference values. In patients with NS, an increase in clot density (D), clot formation rate (V) and clot size (CS) was found, especially when albumin decreased below 25 g/l. Negative correlations were found between the levels of albumin, creatinine and clot density (D), which reflects the level of hyperfibrinogenemia, the rate of clot formation (V) and the integral index of coagulation (CS). The results indicate mainly the activation of the plasma hemostasis due to the internal coagulation pathway. However, the correlation of Tlag (delay time for the onset of clot formation after contact of blood plasma with the insert-activator) with serum cholesterol levels may also indicate activation of the extrinsic coagulation pathway.ConclusionIn CGN patients with NS, activation of the plasma hemostasis is noted, as evidenced by an increase in the rate of formation (V) and size of the clot (CS) after 30 minutes, as well as the density of the formed clot (D).
