The objective of this study is to evaluate the impact of cold ischemia time (CIT) on delayed graft function (DGF) and acute rejection (AR) among deceased donor kidney transplant recipients. The medical records of 111 patients who underwent kidney transplantation from deceased donors between November 1994 and July 2009 were retrospectively analyzed. DGF was observed in 54% of the patients and the prevalence of AR in the first year after transplantation was 9.9%. The incidence of DGF was higher among patients with longer CIT. There was no correlation between CIT and AR episodes. Higher body weight of recipients and donors, history of prior blood transfusion and advanced donor age were related with DGF. Patients with DGF had higher serum creatinine levels at the first, third and fifth years. There was a negative correlation between recipient body weight and creatinine clearance at the first year. CIT has an important role in the development of DGF as a modifiable risk factor. Moreover, donors with advanced age and higher body weight as well as recipients with higher body weight and history of blood transfusions are at risk for the development of DGF. Prevention of DGF may help to improve graft function at the first, third and fifth years and shorten the hospital stay.

The objective of the study is to evaluate the relationship between serum testos-terone levels and cardiovascular risk factors (CVRF) in patients after kidney transplantation and with chronic kidney disease (CKD). Seventy-five male patients, aged between 18 and 68 years, who had kidney transplantation at least six months earlier, were enrolled into the study. Only renal transplant recipients and CKD patients with a creatinine level of 0.05). Serum testosterone levels were independent risk factors affecting IVC collapse index, systolic BP and LA. m-TORi and CNIs drugs might have no negative effect on serum testosterone levels, and improvement of the serum testosterone levels after transplantation might have a positive contribution on cardiac risk factors.
