Abstract

The aim of the study is to investigate the effectiveness of conservative therapy with the inclusion of cryoprecipitate in its composition and its effect on the angiogenesis of renal blood vessels in patients with purulent pyelonephritis.

Materials and methods. The study included 30 patients aged from 20 to 45 years (6 men, 24 women) with acute purulent pyelonephritis. All patients were assessed for markers of angiogenesis in blood plasma: vascular endothelial growth factor (VEGF-A), angiopoietin 1 (Ang1) and angiopoietin 2 (Ang2). The patients were divided into two groups. Patients of group 1 (n = 15) received conservative therapy with the inclusion of cryoprecipitate, patients of group 2 (n = 15) received surgical treatment. The control group consisted of 10 healthy donors aged 20–35 years, whose blood angiogenesis markers were determined to obtain reference values.

Results. In the course of preliminary studies, the blood content of angiogenesis markers was determined in 10 healthy donors. The level of VEGF-A in patients of both groups and the level of Ang1 in patients of group 1 at admission to the hospital significantly exceeded the corresponding values in the control group. In group 2 patients, the level of VEGF-A and Ang1 remained elevated during treatment, which indirectly indicated an ongoing inflammatory process. The level of Ang2 in patients of both groups did not change significantly. Conservative treatment of group 1 patients showed high efficiency, which was confirmed by positive dynamics of clinical and laboratory indicators, as well as data from instrumental examination.

Conclusions. The results obtained indicate the effectiveness of conservative therapy with the administration of cryoprecipitate in patients with purulent pyelonephritis, and the effectiveness of such treatment is comparable to the effectiveness of surgical treatment . The use of cryoprecipitate has an endothelioprotective and anti-inflammatory effect on blood vessels, stabilizes the processes of angiogenesis, which contributes to limiting the inflammatory process and its regression.
