Resumo: |
Background: Hypokalemia is a well-described electrolyte disturbance in patients on peritoneal dialysis (PD). Hyperkalemia, however, is still overlooked, although also represents a risk factor for mortality. Angiotensin-converting enzyme inhibitors and/or angiotensin receptor blockers (ACE/ARB), diuretics, and proton pump inhibitor (PPI) can interfere with potassium levels in these patients. Methods: This is a retrospective study that evaluated monthly serum potassium in a 5-year period. Serum potassium disturbances were evaluated as time-average, and number of hypo- and hyperkalemia episodes per patient. Prescribed medication such as ACE/ARB, diuretics and omeprazole were recorded. Results: We evaluated 2025 potassium measurements obtained from 146 patients on PD. Serum potassium ranged from 2.5 to 8.3 mEq/L with an average of 4.72 ± 0.74 mEq/L. Hypokalemia was found in 59 measurements (2.9%) obtained from 35 patients (23.9%) whereas hyperkalemia was demonstrated in 269 (13.3%) measurements obtained from 74 patients (50.7%). Hypokalemia was associated with low albumin (p=0.022), race (p=0.031) and omeprazole use (p=0.024). Omeprazole-associated hypokalemia was seen only in non-anuric patients and remained an independent risk factor even after adjustments. Patients who had hyperkalemia were more likely to be anuric (p=0.001) and in use of furosemide use (p=0.0001). Conclusion: Hyperkalemia and hypokalemia are very frequent in patients on PD and should be closely monitored. Interventional studies should address the impact of discontinuing omeprazole in the levels of potassium. |
