The benefits and effects of mTORi were assessed in our centre’s cohort. Methods: We analysed graft function, rejection rates, tolerability and discontinuation rates in a retrospective cohort analysis of 44 adult kidney transplant recipients (29 male and 15 female) treated

with mTORi between 2006 to 2012. Results: All patients switched from CNI to mTORi, the reasons for conversion were skin cancers (37%), CNI toxicity/ intolerance (25%), CT99021 datasheet planned reduction in immunosuppression (14%), study trials (7%), BK nephropathy (5%) and others (12%). mTORi had to be discontinued in 15 (34%) patients within 24 months and in 7 (16%) after 24 months because of either rejection, severe see more proteinuria, oedema, muco-cutaneous

effects, leukopenia, pneumonitis, or cerebral venous thrombosis. The eGFR pre-conversion was 56 ± 22 mL/min/1.73 m2 and 63 ± 24 mL/min/1.73 m2 (P < 0.01) at 1 month, but did not differ from pre-conversion at 3, 6, 12 and 24 months. Fourteen (32%) patients experienced biopsy proven rejection (n = 9 cellular, 2 mixed and 3 borderline changes) without association to HLA mismatches, or time of conversion after transplantation. Conclusions: In this retrospective analysis of a small subset of patients, mTORi treatment is associated with early adverse effects

or acute rejection leading to discontinuation of mTORi in up to 50% of patients. mTOR inhibitors are a reasonable therapeutic alternative to CNIs for a only a subset of renal transplantation recipients. 265 HIGH-SENSITIVITY TROPONIN T AS A PREDICTOR OF CARDIOVASCULAR MORBIDITY IN RENAL TRANSPLANT RECIPIENTS Digestive enzyme K FERNANDEZ, C MUNRO, M SURANYI, A MAKRIS, J WONG, H HASSAN Renal Unit Liverpool Hospital, Australia Aim: Determine if any significant change in High-sensitivity troponin T (hsTnT) occurs following renal transplantation. Background: hsTnT is a biomarker for detecting myocardial injury. Its use as a predictor of cardiac events in stable dialysis patients has previously been investigated. It remains uncertain if pre-transplant hsTnT levels offer any predictive value in determining cardiac events post-transplant. Methods: We designed a prospective cohort study in South West Sydney in a non-transplant centre. Serum hsTnT was analysed from 30 dialysis patients pre-transplant and post-transplant. Patients were then classified and analysed according to their pre-transplant hsTnT levels: normal (Group 1 – levels < 14 ng/L) and those with elevated hsTnT (Group 2).
