Prospective characteristic of cardiovascular risk factors in renal transplant recipients

The aim of the study is assess the dynamics of laboratory and instrumental parameters (these are cardiovascular risk factors) in patients with chronic kidney disease in the preoperative period and after renal transplantation.

A single-center prospective cohort study included 43 kidney transplant recipients. Clinical examination, laboratory and instrumental studies were carried out in the preoperative period, in six months and in five years after transplantation. Laboratory tests included a complete blood count, coagulation, biochemical blood test and enzyme-linked immunosorbent assays. The dynamics of structural and functional heart parameters was studied by echocardiography in the preoperative period and in five years.

It was found that the blood pressure, pulse rate, and hypotension episodes decreased after renal transplantation. Hyperaldosterone in the preoperative period was more common than after transplantation. It was observed that the blood level of total cholesterol, triglycerides, interleukin-6, tumor necrosis factor-α, and C-reactive protein decreased in the postoperative period. The hyperglycemia incidence significantly decreased by the end of the observation period. It was detected that the NT-proBNP level increased in all recipients in the preoperative period and decreased to normal values in 37.2 % (n = 16) recipients in the postoperative period. The number of red blood cells and the hemoglobin concentration increased and the hyperethropoietinemia incidence decreased in the postoperative period. The glomerular filtration rate was lower in six months after transplantation than in five years.
