METABOLIC FACTORS HAVE A MAJOR IMPACT ON KIDNEY ALLOGRAFT SURVIVAL

Background At the present time, late graft loss is the major cause of kidney failure after transplantation. However, the influence of metabo lic factors on this process is ill-defined, Methods, To identify the i mpact of lipid metabolism, glucose metabolism, and blood pressure and their prognostic value for graft survival, data for all recipients of a kidney allograft with a potential graft survival of >15 years and a minimum graft survival of 1 month were analyzed retrospectively. Recip ients of kidney grafts functioning more than 15 years (n=32) were comp ared with those with a graft function of less than 10 years (n=152, co ntrols) and evaluated in a multivariate analysis, Results. Low levels of serum cholesterol, triglycerides, and glucose, before and after tra nsplantation, were accompanied by a prolonged graft survival. Prognost ic factors for early graft failure included serum triglycerides >300 m g/dl, cholesterol >250 mg/dl before transplantation, serum creatinine >4.0 mg/dl 1 month after transplantation, and donor age above 45 or le ss than 10 years, Additionally, systolic and, particularly, diastolic blood pressure was lower in the group with a prolonged graft function as compared with controls immediately before and after transplantation , In addition, the incidence of primary graft function was lower and t he incidence of acute rejection episodes higher in controls. Cold and warm ischemic time, body mass index, recipient age, and gender did not differ significantly, Conclusions, Our data suggest that metabolic pa rameters play an important role in the process of late graft loss afte r kidney transplantation.
