Chronic kidney disease (CKD) affects 10-15% of the population worldwide, results in high morbidity and mortality, and requires costly treatment and renal replacement therapy. Glomerulosclerosis, tubulointerstitial fibrosis, and persistent intestinal flora disturbance are common in CKD. Short-chain fatty acids (SCFAs), produced by the intestinal microbiota, have been previously reported to ameliorate kidney injury; however, the specific concentrations and types that required to improve renal function remain unknown. The present study aim to evaluate the levels of SCFAs in healthy and CKD patients, and to test the hypothesis...

ConclusionAlthough the metabolic picture is complex, we suggest oxidative stress, the gut-kidney axis, acid –base balance, and energy metabolism as promising areas for future investigation.

AbstractBackgroundHyperphosphatemia control is a major issue in hemodialysis patients. Both sevelamer and nicotinamide are prescribed for this purpose. In addition, they exert pleiotropic effects such as an improvement of inflammatory status and potentially enhanced clearance of uremic toxins. In the present secondary analysis of the NICOREN trial, we investigated the impact of sevelamer and nicotinamide on uremic toxins, toxin precursors, and endotoxemia in chronic hemodialysis patients.MethodsCirculating uremic toxins (including phenylacetylglutamine, trimethylamine-N-oxide, p-cresyl sulfate, indoxyl sulfate, kynurenine,...

Abstract The gut microbiota is considered to be a novel important factor to take into account in the pathogenesis of chronic kidney disease and uremia. Much attention has been paid to specific uremic retention solutes of microbial origin, such as indoxyl sulfate, p-cresyl sulfate, and trimethylamine-N-oxide. However, other novel less well studied compounds, such as hydrogen sulfide and related sulfur metabolites (sulfane sulfur, lanthionine, etc.), should be included in a more comprehensive appraisal of this topic, in light of the potential therapeutic opportunities for the future.

AbstractPurpose of ReviewTrimethylamine N-oxide (TMAO) is a gut microbiota-dependent metabolite produced from choline and phosphatidylcholine. Trimethylamine N-oxide was found associated with enhanced atherosclerosis and thrombosis in vitro and in vivo. We summarized available clinical studies which investigated TMAO ’s role in predicting prognostic outcomes, including mortality, in patients with cardiovascular diseases.Recent FindingsIn chronic kidney disease cohorts, higher TMAO levels were significantly associated with higher mortality from 1.18 to 4.32 folds. Higher TMAO levels were not significantly associated w...

ht AJ Abstract Chronic kidney disease (CKD) is an aging-related disorder that represents a major global public health burden. Current biochemical biomarkers, such as serum creatinine and urinary albumin, have important limitations when used to identify the earliest indication of CKD or in tracking the progression to more advanced CKD. These issues underline the importance of finding and testing new molecular biomarkers that are capable of successfully meeting this clinical need. The measurement of changes in nature and/or levels of proteins and metabolites in biological samples from patients provide insights into ...

Conclusion: Alterations in metabolites and relevant pathways were significantly different between the CKD- and HFD-induced IR rats. These findings may offer important information regarding the pathogenesis specific to IR caused by the decline in the renal function.Kidney Blood Press Res 2018;43:1199 –1211

Abstract More than half of all deaths among end stage renal disease (ESRD) patients are due to cardiovascular disease (CVD). Cardiovascular changes secondary to renal dysfunction, including fluid overload, uremic cardiomyopathy, secondary hyperparathyroidism, anemia, altered lipid metabolism, and accumulation of gut microbiota-derived uremic toxins like trimethylamine N-oxidase, contribute to the high risk for CVD in the ESRD population. In addition, conventional hemodialysis (HD) itself poses myocardial stress and injury on the already compromised cardiovascular system in uremic patients. This review will provide...
