    Abstract:
    INTRODUCTION: Renal transplantation provides longer life expectancy in patients with renal failure. Nonetheless, this improved life expectancy is still shorter than that for the general population. The main couse of death in renal transplant patients is cardiovascular disease, and chronic allograft nephropathy is the most significant cause of graft loss. Genetic polymorphisms of the renin angiotensin system have been implicated in both chronic allograft nephropathy and fatal cardiovascular diseases. AIM: The long term goal of the authors was to improve the survival of renal transplanted patients. The authors aimed to identify novel biomarkers which correlate with the survival of the transplant organ and the recipient with a special attention to elements of the renin-angiotensin system. METHOD: A retrospective clinical trial was performed involving 72 renal transplanted patients. Angiotensin-converting enzyme I/D genotypes and activity, kidney function and morphological properties of the heart were determined. RESULTS: A significant positive correlation was found between the DD genotype of the angiotensin-converting enzíme gene, and the DD genotype predicted severe left ventricular hypertrophy. CONCLUSIONS: These findings suggest that the I/D genotypes of the angiotensin-converting enzyme gene predict not only the expected survival of the transplanted organ, but also that of the patient. Patients with the DD genotype are more susceptible for transplant failure. These patients should be identified and a special attention should be made on their pharmacological treatment (renin-angiotensin system inhibition), and their complience should also be maintained.
