title: Serum Potassium Profile and Associated Factors in Incident Peritoneal Dialysis Patients.
abstract: OBJECTIVE
  Abnormal potassium profiles are common in peritoneal dialysis (PD) patients. We studied the factors associated with serum potassium profiles in incident PD patients.
  
  
  METHODS
  Patients were enrolled from two hospital-facilitated PD centers from May 2013 to May 2016 and January 2009 to December 2015. A total of 319 incident PD patients were examined for factors associated with serum potassium profile. Average serum potassium levels were obtained for analysis during the first 3 months after PD initiation. Clinically factors and parameters associated with PD were assessed by logistic regression.
  
  
  RESULTS
  There were 168 men and 151 women (mean age, 50.8 years). Blood urea nitrogen (BUN), creatinine (Cr), and intact parathyroid hormone levels were significantly increased in patients in the higher serum potassium group. There were no significant risk factors for hypokalemia, including sex, age, diabetes, blood examination parameters, medication use, or PD-related parameters by multivariate logistic regression analysis. BUN (adjusted odds ratio [OR] 1.02, 95% CI 1.01-1.03, p = 0.001) and Cr (adjusted OR 1.08, 95% CI 1.01-1.16, p = 0.029) levels were significant risk factors for hyperkalemia by multivariate logistic regression analysis.
  
  
  CONCLUSIONS
  Hyperkalemia and blood BUN and Cr levels were significantly associated in incident PD patients.
