BACKGROUNDSarcopenia and myosteatosis are indicators of abnormal body composition (BC). Computed tomography (CT) imaging has proven to be an accurate modality for BC quantification in kidney transplantation (KT). We tested whether pre-KT CT-based BC was associated with both all-cause graft loss (ACGL) and mortality among adult recipients from two centers (Johns Hopkins Hospital [JHH] and University Medical Center Groningen [UMCG]).METHODSPatients who underwent a KT between 2003 and 2020 were followed for a median (interquartile range) follow-up of 6.4 (4.6-8.5) years at JHH and 6.3 (5.1-7.5) years at UMCG. Cox proportional hazard models were used to estimate the associations of BC with ACGL/ mortality. Fine and Gray regression analysis was performed to assess the association between BC and death-censored graft loss. Prior to KT, 49% of recipients had sarcopenia and 66% had myosteatosis.RESULTSIn total 608 patients were included from JHH (N= 294) and UMCG (N=314). Sarcopenia was not associated with post-KT outcomes. Myosteatosis was associated with a higher risk of ACGL (adjusted hazard ratio 1.78, 95%CI:1.08 - 2.93) and mortality (adjusted hazard ratio 2.35, 95%CI: 1.27 - 4.33) at JHH, but showed no significant association at UMCG after adjusting for confounders. Myosteatosis did not show a significant association with death-censored graft loss at both centers.CONCLUSIONMyosteatosis ascertained from existing CT scans could help identify recipients at higher risk for ACGL who may benefit most from prehabilitation.

BACKGROUNDTo facilitate personalized treatment of diabetic kidney disease (DKD), we developed the Joslin Kidney Panel (JKP) of 21 circulating proteins associated with progression to end-stage kidney disease (ESKD). Prognostic models using baseline concentrations of JKP proteins in circulation and clinical markers were then developed to stratify individuals according to ESKD risk and according to response to fenofibrate, a potential reno-protective drug.METHODSThe custom-made Joslin OLINK multipurpose proteomics platform was used to quantify JKP proteins. Association between baseline serum/plasma concentrations of these proteins and kidney outcomes was examined in five independent study groups.RESULTSIn Type 1 diabetes individuals from Joslin (N=59), FinnDiane (N=389), and Steno (N=283), all JKP proteins were good discriminators of ESKD risk during 10-year follow-up. Baseline concentrations of KIM-1 and WFDC2 performed the best, matching or outperforming the clinical markers. An optimal model to discriminate ESKD risk that included three clinical markers and eight JKP proteins (KIM1, TNF-R2, TNF-R3, TNF-R19L, PVRL4, WFDC2, DLL1, SYND1), was developed using the FinnDiane cohort (C-index 0.868, SE±0.019) and validated in the Steno cohort (C-index 0.913, SE±0.104) and in Type 2 diabetes Joslin study (C-index 0.807, SE±0.036). In each of these studies the optimal model performed better than models based solely on three clinical markers. In a subgroup of 450 individuals with Type 2 diabetes from the ACCORD-Lipid trial, high levels of three JKP proteins (EFNA4, DLL1, IL-1RT1) predicted amelioration of fast kidney function decline during four years of follow-up in those treated with fenofibrate compared to placebo.CONCLUSIONQuantification of circulating JKP proteins using the Joslin OLINK platform discriminates ESKD risk in individuals with diabetes and their response to reno-protective drugs. Use of this multi-purpose precision medicine tool should facilitate studies on the etiology of DKD and enable the development of effective personalized treatment protocols for individuals with DKD.
