Chronic kidney disease (CKD) is associated with high morbidity and mortality. In many patients CKD is diagnosed late during disease progression. Therefore, the implementation of potential biomarkers may facilitate the early identification of individuals at risk. Trefoil factor family (TFF) peptides promote restitution processes of mucous epithelia and are abundant in the urinary tract. We therefore sought to investigate the TFF peptide levels in patients suffering from CKD and their potential as biomarkers for CKD. We analysed TFF1 and TFF3 in serum and urine of 115 patients with CKD stages 1–5 without dialysis by ELISA. 20 healthy volunteers served as controls. Our results showed, that urinary TFF1 levels were significantly increased with the onset of CKD in stages 1–4 as compared to controls and declined during disease progression (p = 0.003, < 0.001, 0.005, and 0.007. median concentrations: 3.5 pg/mL in controls vs 165.2, 61.1, 17.2, and 15.8 pg/mL in CKD 1–4). TFF1 and TFF3 serum levels were significantly elevated in stages 3–5 as compared to controls (TFF1: p < 0.01; median concentrations: 12.1, 39.7, and 34.5 pg/mL in CKD 3–5. TFF3: p < 0.001; median concentrations: 7.1 ng/mL in controls vs 26.1, 52.8, and 78.8 ng/mL in CKD 3–5). TFF3 excretion was increased in stages 4 and 5 (p < 0.001; median urinary levels: 65.2 ng/mL in controls vs 231.5 and 382.6 ng/mL in CKD 4/5; fractional TFF3 excretion: 6.4 in controls vs 19.6 and 44.1 in CKD 4/5). ROC curve analyses showed, that monitoring TFF peptide levels can predict various CKD stages (AUC urinary/serum TFF > 0.8). In conclusion our results show increased levels of TFF1 and TFF3 in CKD patients with a pronounced elevation of urinary TFF1 in lower CKD stages. Furthermore, TFF1 and TFF3 seems to be differently regulated and show potential to predict various CKD stages, as shown by ROC curve analysis.
BackgroundPostoperative complications are still a major concern after liver resection (LR). Systemic inflammation and deregulated reactive oxygen species during major abdominal surgery may impair outcome after hepatectomy.MethodsPatients undergoing LR were included in this study (n = 40). Oxidative stress (OS) was measured peri- and post-operatively as static oxidation-reduction potential markers (sORP) and antioxidant capacity ORP (cORP) by using the RedoxSYS Diagnostic system. Furthermore, Th1- and Th2-specific cytokines were assessed.ResultsWhereas there was no significant change in systemic sORP during LR and in the early postoperative course, there was a substantial decrease of cORP immediately post-surgery, and on postoperative days 1 and 3 (p<0.001). OS response was tightly regulated, as there was a significant correlation between sORP and cORP (p<0.0001; R2:0.457). An increase of OS (sORP) after LR of more than 3 mV was predictive for severe postoperative complications (53.8% vs. 12.5; p = 0.017). There was a significantly higher IL-2 (p = 0.006) and IL-5 (p = 0.001) increase during hepatectomy in patients who developed a severe morbidity.ConclusionAntioxidant capacity remained stable during LR but dropped during the post-surgical period, suggesting a consumption of antioxidants to maintain OS within healthy range. Severe postoperative complications were associated with a pronounced inflammatory response during surgery.
Background. Destruction of the endothelial glycocalyx has been observed within lung and kidney grafts during ischemic organ preservation. We aimed to quantify glycocalyx damage within human liver grafts after organ preservation and correlate the results with graft injury and postoperative graft function in patients undergoing orthotopic liver transplantation (OLT). Methods. Syndecan-1 (Sdc-1) was measured as indicator of glycocalyx degradation in effluents of 38 liver grafts and serum of patients undergoing OLT. Effluent Sdc-1 concentrations were correlated with hepatic injury markers from the effluent. Furthermore, we assessed the association of Sdc-1 with early allograft dysfunction (EAD), 1-year graft survival, and 1-year patient survival. Results. Effluent Sdc-1 concentrations correlated with effluent concentrations of hepatocellular injury markers, including alkaline phosphatase (R = 0.543, P = 0.003), aspartate aminotransferase (R = 0.420, P = 0.029), and lactate (R = 0.574, P = 0.002). Sdc-1 effluent concentrations were greater in patients who developed EAD compared with those without EAD (4720 [4374–5133] vs 3838 [3202–4240] ng/mL, P = 0.015). Furthermore, receiver operating characteristics analyses revealed that effluent Sdc-1 concentrations (AUC = 0.82, P = 0.017) and serum Sdc-1 concentrations (AUC = 0.84, P = 0.006) were associated with the development of EAD. These results were confirmed by regression analyses. No association was found between Sdc-1 and 1-year graft survival or 1-year patient survival. Conclusions. Our data suggest that the glycocalyx is damaged within human liver grafts during preservation and the extent of glycocalyx damage correlates with the severity of hepatocellular injury. Recipients of livers grafts with greater glycocalyx damage might be at higher risk for development of EAD after OLT.
