Dietary intake of potassium does not appear to be a significant factor in the development of hyperkalemia in patients with chronic kidney disease (CKD), according to research presented at the 56th European Renal Association-European Dialysis and Transplant Association Congress in Budapest, Hungary.

Christiane Ramos, PhD, of Federal University of Sao Paulo in Brazil, and colleagues evaluated 3-day food diaries from 96 nondialysis CKD patients (15% stage 5 CKD; mean age 67 years; 52% men). Hyperkalemia (serum potassium levels exceeding 5 mEq/L) developed in 36 patients (38%). Despite minor differences in daily potassium intake or servings of fruits, vegetables, legumes, cereals, dairy, and meats, investigators observed no significant associations between those with and without hyperkalemia.

The investigators also examined medication use and other relevant factors. After logistic regression analysis, only diabetes mellitus and lower serum bicarbonate levels were independently associated with greater hyperkalemia risk.
