OBJECTIVES: Calcineurin inhibitors are the cornerstone of immunosuppression following solid-organ transplant. However, hyperkalemia may occur by multiple mechanisms affecting potassium in the distal tubule. Hyperkalemia is commonly observed in renal transplant recipients, and it is dose-dependent. Here, we evaluated the impact of fludrocortisone in the management of calcineurin inhibitor-induced hyperkalemia after renal transplant.
MATERIALS AND METHODS: We evaluated newly transplanted patients who developed hyperkalemia or those with hyperkalemia who attended our outpatient renal transplant clinic (Hamed Al-Essa Organ Transplant Center, Kuwait). Clinical and laboratory parameters were collected before starting fludrocortisone (baseline values) and then at 1, 2, 4, and 8 weeks. Drug history was assessed, with any drugs that could induce hyperkalemia being discontinued (such as spironolactone); otherwise, essential drugs like prophylactic agents (sulfamethoxazole-trimethoprim) were maintained. Oral anti-hyperkalemic doses (bicarbonate, resonium calcium, fludrocortisone) were noted.
RESULTS: Our study included 29 patients; most were men (aged 45.8 ± 15 years). Body weight did not significantly change after introduction of fludrocortisone (79.53 ± 24.31, 79.82 ± 23.85, 80.62 ± 24.24, 77.03 ± 20.7, and 79.21 ± 27.93 kg at baseline and at postdose week 1, 2, 4, and 8, respectively). Systolic and diastolic blood pressure levels were also similar at baseline versus postdose. Steroid doses (prednisolone) were significantly reduced over 1 month (15.7 ± 12.4, 14.1 ± 10.19, 12.6 ± 8.7, 9.5 ± 5.2, and 9.5 ± 5.2 mg/ day). Serum potassium levels significantly improved (5.18 ± 0.58, 4.9 ± 0.49, 4.8 ± 0.54, 4.8 ± 0.65, and 4.4 ± 0.72 mmol/L). Serum creatinine levels significantly improved by postdose week 8 (129.28 ± 48.9, 130.92 ± 52.2, 127.66 ± 50.9, 121.42 ± 41.7, and 124.1 ± 51.27 μmol/L). Serum bicarbonate levels remained similar.
CONCLUSIONS: Fludrocortisone was a safe and effective option in management of calcineurin inhibitor-induced hyperkalemia among renal transplant recipients.
