Abstract
BACKGROUND: The aim of this study was to evaluate the renal and cardiovascular outcomes of post-transplant c-reactive protein (CRP) levels. METHODS: One hundred fifty renal transplant recipients (113 men; median age, 38.9 ± 10.8 years) were cross-sectionally analyzed. Mean pre-transplant and post-transplant CRP levels were analyzed by the 1(st), 3(rd), 6(th), 12(th), and 24(th) months of transplantation. Patients were divided into 3 groups according to mean post-transplantation CRP levels: group 1 (CRP >20 mg/L and fluctuating levels; n = 34), group 2 (CRP, 6-20 mg/L; n = 40), and group 3 (CRP <6 mg/L; n = 76). Arterial stiffness was measured by means of carotid femoral pulse-wave velocity (PWv) by use of the SphygmoCor system. RESULTS: Patients in group 1 had significantly lower estimated glomerular filtration rate (eGFR) (P = .000) and left ventricular systolic function and higher duration of dialysis before transplantation, pulse-wave velocity (PWv), proteinuria, and left ventricular mass index when compared with the other two groups. In regression analysis, eGFR and PWv were detected as the predictors of post-transplantation CRP levels. CONCLUSIONS: Fluctuating and high stable (>20 mg/L) post-transplant CRP levels predict eGFR, proteinuria, left ventricular mass index, and PWv after transplantation. Thus, CRP levels may be a useful marker to anticipate graft survival and cardiovascular morbidity in renal transplant recipients.
