Changes in cardiovascular risk factors after renal transplantation

Authors examined the serum concentration of creatinine, uric acid, homocysteine, cystatine C, total cholesterol and triglyceride in 115 male and 77 female patients six months after the transplantation. The change of the BMI (Body Mass Index) was studied, fat and water body weight was determined by bioelectrical impedance analysis, and the ratio of intra- and extracellular volume was calculated. Both creatinine and cystatine C levels decreased significantly compared to the levels before the transplantation (p < 0.001) because of the good renal function, and there was a good correlation between creatinine, cystatine C and homocysteine levels (r = 0.5315 in females, r = 0.3189 in males). Elevated BMI (36.49%) and hypercholesterolaemia along with moderate hyperhomocysteinaemia was found in a considerable part of the patients. Increase in body weight was confirmed by the increase in fat body weight and volume determined by bioelectrical impedance analysis. In patients with adequate compliance the ratio of intra- and extracellular volume was between 1.67 and 1.79. Blood pressure values showed frequently the non-dipper phenomenon despite appropriate antihypertensive therapy, and negative diurnal index was found with high nocturnal blood pressure levels. The mean blood pressure was 148/81 +/- 13.2/4.8 mmHg in males and 133/84 +/- 15.3/9.8 mmHg in females. Authors enhance the importance of regular monitoring of cardiovascular risk factors in the prevention of cardiovascular complications.
