Effects of sleep status on renal function in patients with chronic kidney disease: a systematic review

摘要

Objective:To systematically evaluate the effects of sleep status on renal function in patients with chronic kidney disease (CKD).Methods: To search the relevant literature related to the effects of sleep status on renal function of CKD patients on PubMed database, EMBase database, the Cochrane Library database, CNKI database, Chinese Biomedical Literature Database, VIP and Wanfang database from the initial to June 2018, all literature that met the criteria were included. According to the type of studies, the quality of the literature was evaluated by NOS scale in the cohort study and AHRQ scale in the cross-sectional study, and systematically evaluated the outcome indicators, the main outcome indicators were estimated glomerular filtration rate (eGFR) and endogenous creatinine clearance rate (Ccr), while the secondary indicators were Pittsburgh Sleep Quality Index (PSQI), Sleep Quality (SQ), Serum Creatinine (Scr), Hemoglobin (Hb), Albumin (ALB) and Urine Protein/Creatinine Ratio (UPCR).Results: Four literature and one meeting abstract were included in this study, of which four were cohort studies, three of them the NOS quality evaluations were high, one of them was medium, the remaining one was cross-sectional study, and the AHRQ quality evaluation was medium. This study shows that sleep status has a certain correlation with renal function. Shorter sleep time or poor sleep quality can lead to deterioration of renal function. Among them, the research data of Sabbatinit research team in Italy showed that Ccr gradually decreased with the increased of the PSQI;studies of Cohen research team and the Ricardo research team in the United States showed that eGFR decreased with the increased of the PSQI;the study of Kumar research team in the United States showed that the lower SQ , the worse renal function;the study of Knutson'' research team in British showed that the shorter sleep time, the lower eGFR. In addition, studies showed that sleep index also has influence on Hb, ALB, Scr, UPCR and other indicators.Conclusion: Sleep status can affect the renal function of CKD patients in different degrees. Shorter sleep time and poor sleep quality will damage renal function and accelerate the progress of CKD.
