[Current status of hyperkalemia in dialysis patients in China].

To investigate the prevalence and associated factors of hyperkalemia in dialysis patients. Patients underwent hemodialysis (HD) and peritoneal dialysis (PD) from multi-center databases were recruited from January 2017 to December 2019, and those aged ≥18 years and with dialysis duration ≥3 months were included to analyze the prevalence and related factors of hyperkalemia. A total of 12 364 patients were enrolled in the study, and 6 836 cases were men. The average age of the patients was (51±15) years. Among these patients, 4 230 cases underwent HD while 8 134 received PD. Hyperkalemia was detected in 20.7% (2 554/12 364) of the patients while hypokalemia was found in 17.0%(2 102/12 364) of the patients. Multivariate logistic regression showed that HD (=2.25, 95%: 1.54-3.30), diabetes mellitus (DM) (=1.65, 95%: 1.17-2.32), high body mass index (BMI) (=1.06, 95%: 1.03-1.09), high levels of serum albumin (=1.04, 95%: 1.01-1.07) and phosphorus (=3.12, 95%: 2.44-4.00), low levels of serum bicarbonate (=0.89, 95%: 0.87-0.92), triglycerides (=0.76, 95%: 0.68-0.85) and creatinine (=0.95, 95%: 0.90-0.99), usage of angiotensin converting enzyme inhibitor/Angiotensin Ⅱ receptor antagonist (ACEI/ARB, =1.38, 95%: 1.11-1.72) and beta-blocker (=1.32, 95%: 1.07-1.64) were associated with hyperkalemia. Hyperkalemia occurred in 20.7% of the dialysis patients. HD, DM, high BMI, high levels of serum albumin and phosphorus, low levels of serum bicarbonate, triglycerides and creatinine, use of ACEI/ARB were associated with hyperkalemia.
