  Introduction: Noninvasive biomarkers that reflect tubular health and allow early recognition of accelerated graft fibrosis development are warranted. Serum uromodulin (sUmod) and urinary epidermal growth factor (uEGF) originate from kidney tubules and may reflect functional nephron mass. The aim of this study was to investigate the associations between sUmod and uEGF with measured glomerular filtration rate (mGFR) and kidney allograft interstitial fibrosis percentage (IF%) score. Methods: sUmod and uEGF measurements, mGFR by iohexol-clearance and kidney allograft biopsies were obtained from kidney transplant recipients (KTRs) included in the Omega-3 fatty acids in Renal Transplantation (ORENTRA) trial at 8 weeks (baseline) and at 1 year after transplantation (end of study). Associations were analyzed with univariable and multivariable linear regression. Results: Ninety patients at baseline and 48 patients at end of study had complete study variable assessments. uEGF normalized to urinary creatinine (uEGF/Cr) was associated with mGFR both at baseline (standardized β-coefficient [Std. β-coeff] = 0.457 [p = <0.001]) and at end of study (Std. β-coeff = 0.637 [p = <0.001]). sUmod was only associated with mGFR at end of study (Std. β-coeff = 0.443 [p = 0.002]). uEGF/Cr, sUmod, and mGFR were associated with graft IF% score both at baseline (Std. β-coeff = −0.349 [p = 0.001], −0.274 [p = 0.009] and −0.289 [p = 0.006], respectively) and at end of study (Std. β-coeff = −0.365 [p = 0.011], −0.347 [p = 0.016] and −0.405 [p = 0.004], respectively). The results remained largely unchanged in multivariable analysis. Conclusion: uEGF/Cr and sUmod were associated with mGFR and graft IF% score. Our results indicate a possible role of uEGF/Cr and sUmod in the follow-up of KTRs.

  BACKGROUND: Previous reports indicate that posttransplantation diabetes mellitus (PTDM) is associated with overall renal graft loss, but not death-censored graft loss. METHODS: In this single-center retrospective cohort study of 2749 adult Norwegian renal transplant recipients, transplanted between 1999 and 2011, we estimated overall and death-censored renal graft loss hazard ratios in patients diagnosed with PTDM, impaired glucose tolerance and diabetes before transplantation, using multivariable Cox proportional hazard regression analysis. RESULTS: A total of 893 renal grafts were lost during the study period, either due to recipient death (n = 540) or death-censored graft loss (n = 353). When the observational time started at time of transplantation, diabetes before transplantation was associated with both overall and death-censored graft loss. Pretransplantation diabetes was also associated with a steeper decline in renal graft function, a higher risk of acute rejections and more renal grafts lost due to acute rejection. In patients with a functional renal graft 1 year after transplantation, PTDM was associated with overall graft loss (hazard ratio, 1.46; 95% confidence interval, 1.13-1.88; P < 0.001), but not death-censored graft loss (hazard ratio, 1.25; 95% confidence interval, 0.80-1.96; P = 0.33). We found no significant associations between PTDM and change in renal function during the first 5 years or acute rejection risk during the first year after renal transplantation. Impaired glucose tolerance was not associated with either overall or death-censored graft loss. CONCLUSIONS: The present study confirms previous findings of an increased risk of overall but not death-censored renal graft loss in renal transplant recipients with PTDM. Longstanding diabetes might increase the risk of acute rejections.

  OBJECTIVE: Marine n-3 polyunsaturated fatty acids (PUFAs) exert potential anti-inflammatory effects and might improve long-term outcomes after renal transplantation. We assessed associations between plasma phospholipid levels of marine n-3 PUFAs and plasma inflammatory biomarkers 10 weeks after renal transplantation. DESIGN: Cross-sectional single-center study. SUBJECTS: A study population of 861 renal transplant recipients transplanted at Oslo University Hospital between 2007 and 2011. METHODS AND MAIN OUTCOME MEASURE: Plasma phospholipid fatty acids were determined by gas chromatography. Marine n-3 PUFA levels were defined as the sum of eicosapentaenoic acid, docosahexaenoic acid, and docosapentaenoic acid levels in weight percentage of total plasma phospholipid fatty acids. Plasma inflammatory biomarkers were measured by enzyme immunoassays. We used multivariable linear regression analysis to assess associations between levels of marine n-3 PUFAs and inflammatory biomarkers in plasma. RESULTS: Plasma marine n-3 PUFA levels were inversely associated with plasma levels of proinflammatory biomarkers soluble tumor necrosis factor receptor 1 (standardized regression coefficient -0.11, P < .001) and interleukin-6 (standardized regression coefficient -0.09, P = .01). In contrast, there was no association between plasma levels of marine n-3 PUFAs and the anti-inflammatory mediator interleukin-10. CONCLUSIONS: In this renal transplant cohort, inverse associations between plasma levels of marine n-3 PUFAs and markers of inflammation were demonstrated.
