Abstract
AIM
To assess the significance of symmetrical dimethylarginine (SDMA), uromodulin, retinol-binding protein 4 (RSB-4), transforming growth factorb1 (TGF-b1), plasminogen activator inhibitor 1 (PAI-1) as kidney dysfunction potential biomarkers persons with hypertension in persons 2545 years old.
MATERIALS AND METHODS
The study included 147 people. Hypertension was recorded with blood pressure (BP)140/90 mm Hg, renal dysfunction with GFRCKD-EPI90 ml/min/1.73 cm2. Four groups were formed: 1 individuals with hypertension and GFR90 ml/min/1.73 cm2; 2 with hypertension and GFR90 ml/min/1.73 cm2; 3 with BP140/90 mm Hg and GFR90 ml/min/1.73 cm2; 4 with BP140/90 mm Hg and GFR90 ml/min/1.73 cm2. The groups were comparable by gender, age, and number of respondents. Creatinine, SDMA, uromodulin, RSB-4, TGF-b1, PAI-1 levels were examined in all individuals in the serum.
RESULTS
The maximum values of SDMA were determined in the 1st and 3rd groups (1.30 and 1.36 mol/l). In the 1st group, an association was found between SDMA and GFR (r=-0.324;p=0.048). In the 1st group, the minimum values of uromodulin were recorded, in the 4th group the maximum values (164.86 and 188.90 ng/ml; at the same timeр=0.921). The level of RSB-4 was the highest in the 1st group, the lowest in the 4th group (88.64 and 80.05 g/ml;p=0.011). The association of RSB-4 with SDMA in the 3rd group (r=0.400;p=0.017), the 4th group (r=0.403;p=0.018) was detected. The level of TGF-b1 was 1.5 times higher in the 1st group than in the 3rd (23.16 and 15.99 g/ml;p=0.026), the association of TGF-b1 with GFR in the 1st group had the opposite direction (r=-0.452;p=0.005). The study of similar indicators of PAI-1 did not reveal its relationship with renal dysfunction in hypertension.
CONCLUSION
The results of the study made it possible to consider SDMA, RSB-4, TGF-b1 as potential biomarkers of renal dysfunction in hypertension in persons 2545 years old.
