Safe and effective anticoagulation is the key to successful blood purification. Compared with traditional systemic anticoagulation, regional citrate anticoagulation (RCA) has the advantages of prolonging the life of extracorporeal circulation and reducing bleeding complications. However, the complex protocol, the disorder of electrolyte and acid-base status and the accumulation risk in special populations have dissuaded many clinicians. This review starts with the clinical monitoring of RCA, then analyzes the causes and treatments of complications. The risk assessments in special populations were also introduced in order to the widely promotion of RCA in critically ill patients.
End-stage renal disease is a late complication of chronic kidney disease (CKD) and one of the leading causes of high mortality worldwide. Over the years, the impacts of gut microbiota and their associated uremic toxins on kidney diseases through the intricate “gut-kidney axis” have been extensively studied. However, translation of microbiome-related omics results into specific mechanisms is still a significant challenge. In this paper, we review the interaction between gut microbiome and blood purification, as well as the current microbiota-based therapies in CKD. Additionally, the current sequencing technologies and progresses in the gut microbiome research are also discussed.
