To investigate the predictive value of procalcitonin (PCT) in patients with stage 1-4 and stage 5 chronic kidney disease (CKD). ⋯ The baseline PCT level of CKD patients is negatively correlated with renal function. In both CKD1-4 and CKD5 patients, the predictive value of PCT for local infection is not as good as that of CRP, while it has a significant advantage in predicting sepsis.

Observational Study
Evaluation of the tolerability and efficacy of sodium polystyrene sulfonate for long-term management of hyperkalemia in patients with chronic kidney disease.
Sodium polystyrene sulfonate (SPS) is a cation-exchanging resin that has been widely used for several decades as first-line therapy of mild chronic hyperkalemia in patients with chronic kidney disease (CKD). However, evidence to prove the long-term tolerability and efficacy of SPS for the treatment of this condition is still missing. ⋯ This study suggests that low-dose SPS is well-tolerated and can effectively normalize elevated serum potassium over several weeks in CKD outpatients with mild chronic hyperkalemia.
