- Kidney transplant recipients (KTRs) have an increased cancer risk compared to the general population, but absolute risks that better reflect the clinical impact of cancer are seldom estimated. All KTRs in Sweden, Norway, Denmark, and Finland, with a first transplantation between 1995 and 2011, were identified through national registries. Post-transplantation cancer occurrence was assessed through linkage with cancer registries. We estimated standardized incidence ratios (SIR), absolute excess risks (AER), and cumulative incidence of cancer in the presence of competing risks. Overall, 12 984 KTRs developed 2215 cancers. The incidence rate of cancer overall was threefold increased (SIR 3.3, 95% confidence interval [CI]: 3.2-3.4). The AER of any cancer was 1560 cases (95% CI: 1468-1656) per 100 000 person-years. The highest AERs were observed for nonmelanoma skin cancer (838, 95% CI: 778-901), non-Hodgkin lymphoma (145, 95% CI: 119-174), lung cancer (126, 95% CI: 98.2-149), and kidney cancer (122, 95% CI: 98.0-149). The five- and ten-year cumulative incidence of any cancer was 8.1% (95% CI: 7.6-8.6%) and 16.8% (95% CI: 16.0-17.6%), respectively. Excess cancer risks were observed among Nordic KTRs for a wide range of cancers. Overall, 1 in 6 patients developed cancer within ten years, supporting extensive post-transplantation cancer vigilance.

- Background. Although short-term graft survival has improved substantially in renal transplant recipients, long-term graft survival has not improved over the last decades. The lack of knowledge of specific causes and risk factors has hampered improvements in long-term allograft survival. There is an uncertainty if inflammation is associated with late graft loss. Methods. We examined, in a large prospective trial, the inflammation markers high-sensitivity C-reactive protein (hsCRP) and interleukin-6 (IL-6) and their association with chronic graft dysfunction. We collected data from the Assessment of Lescol in Renal Transplant trial, which recruited 2102 maintenance renal transplant recipients. Results. Baseline values were hsCRP 3.8 +/- 6.7 mg/L and IL-6 2.9 +/- 1.9 pg/mL. Adjusted for traditional risk factors, hsCRP and IL-6 were independently associated with death-censored graft loss, the composite end points graft loss or death and doubling of serum creatinine, graft loss or death. Conclusion. The inflammation markers hsCRP and IL-6 are associated with long-term graft outcomes in renal transplant recipients.

- Background. Hyperparathyroidism is reported in 10% to 66% of renal transplant recipients (RTR). The influence of persisting hyperparathyroidism on long-term clinical outcomes in RTR has not been examined in a large prospective study. Methods. We investigated the association between baseline parathyroid hormone (PTH) levels and major cardiovascular events, renal graft loss, and all-cause mortality by Cox Proportional Hazard survival analyses in 1840 stable RTR derived from the Assessment of LEscol in Renal Transplantation trial. Patients were recruited in a mean of 5.1 years after transplantation, and follow-up time was 6 to 7 years. Results. Significant associations between PTH and all 3 outcomes were found in univariate analyses. When adjusting for a range of plausible confounders, including measures of renal function and serum mineral levels, PTH remained significantly associated with all-cause mortality (4% increased risk per 10 units; P = 0.004), and with graft loss (6% increased risk per 10 units; P < 0.001), but not with major cardiovascular events. Parathyroid hormone above the upper limit of normal (65 pg/mL) indicated a 46% (P = 0.006) higher risk of death and an 85% higher risk of graft loss (P < 0.001) compared with low/normal values. Conclusions. Hyperparathyroidismis an independent, potentially remediable, risk factor for renal graft loss and all-cause mortality in RTR.

- BackgroundInflammatory markers show significant associations with cardiovascular events and all-cause mortality after kidney transplantation. Neopterin, reflecting interferon--release, may better reflect the proinflammatory state of recipients than less specific markers. MethodsKidney transplant recipients in the Assessment of LEscol in Renal Transplant (ALERT) trial were examined and investigated for an association between serum neopterin and subsequent clinical events: graft loss, major cardiovascular events (MACE) and all-cause mortality. ResultsAfter adjustment for established and emerging risk factors neopterin expressed as neopterin-to-creatinine ratio was significantly associated with MACE (p=0.009) and all-cause mortality (p=0.002). Endpoints were more frequent with increasing quartiles of neopterin-to-creatinine ratio. The incidence rates of MACE and all-cause mortality were significantly increased in the upper quartiles compared with the first. ConclusionsThis long-term prospective analysis in stable kidney allograft recipients suggests that neopterin is associated with long-term risk of cardiovascular events and all-cause mortality, but not renal outcomes.

- BACKGROUND: Elevated symmetric dimethylarginine (SDMA) has been shown to predict cardiovascular events and all cause mortality in diverse populations. The potential role of SDMA as a risk marker in renal transplant recipients (RTR) has not been investigated. METHODS: We analyzed SDMA in the placebo arm of the Assessment of Lescol in Renal Transplantation study, a randomized controlled trial of fluvastatin in RTR. Mean follow-up was 5.1 years. Patients were grouped into quartiles based on SDMA levels at study inclusion. Relationships between SDMA and traditional risk factors for graft function and all-cause mortality were analyzed in 925 RTR using univariate and multivariate survival analyses. RESULTS: In univariate analysis, SDMA was significantly associated with renal graft loss, all-cause death, and major cardiovascular events. After adjustment for established risk factors including estimated glomerular filtration rate, an elevated SDMA-level (4th quartile, >1.38 mumol/L) was associated with renal graft loss; hazard ratio (HR), 5.51; 95% confidence interval (CI), 1.95-15.57; P=0.001, compared to the 1st quartile. Similarly, SDMA in the 4th quartile was independently associated with all-cause mortality (HR, 4.56; 95% CI, 2.15-9.71; P<0.001), and there was a strong borderline significant trend for an association with cardiovascular mortality (HR, 2.86; 95% CI, 0.99-8.21; P=0.051). CONCLUSION: In stable RTR, an elevated SDMA level is independently associated with increased risk of all-cause mortality and renal graft loss.

- BackgroundIt is well established that post-transplantation anemia (PTA) in renal transplant recipients (RTRs) is associated with reduced graft survival. However, there is an uncertainty of the effect of PTA on cardiovascular events and all-cause mortality. We examined prospectively in a large cohort of erythropoietin-naive patients the effects of PTA on cardiovascular morbidity, patient survival, and graft survival. MethodsA prospective cohort study of RTRs (n=2102) included in the ALERT study. Cox regression models were used to evaluate the impact of PTA on study endpoints: first occurrence of a major adverse cardiac event, all-cause death, and the incidence of death-censored graft loss. Mean follow-up was 6.7yr. All endpoints were adjudicated by an independent endpoint committee. ResultsTwenty-nine percent of women and 30% of men were anemic. Hemoglobin levels were not associated with any effect on cardiovascular morbidity and mortality (HR 0.97 [0.90-1.05] per g/dL, p=0.48) or all-cause death (HR 0.96 [0.90-1.03] per g/dL, p=0.24) after extensive multivariate adjustments for clinical and demographic factors. Hemoglobin levels were negatively associated with graft loss (HR 0.86 [0.80-0.92] per g/dL, p<0.001). ConclusionsPTA was not associated with an increased incidence of cardiovascular morbidity and mortality or all-cause mortality.
