abstract

  • Twenty-four normotensive males in complete remission (CR) for 9+ to 54+ months after cisplatin-based chemotherapy for metastatic germ-cell tumors were evaluated for evidence of alterations in the renin-aldosterone axis and renal function. Abnormally high ambulatory plasma renin activity was seen in 14 of 19 patients with 24-hour urine sodium excretion greater than 50 mEq. This was correlated with elevated ambulatory plasma aldosterone (P = .009) and 24-hour urinary aldosterone excretion (P = .01). The mean serum magnesium value (1.34 +/- .05 mEq/L) was subnormal. Therapy resulted in an increase in serum creatinine during treatment (P less than .0001), an increase in BUN (P less than .01), and decrease in serum phosphorus (P less than .001). The relationship between the alterations in the renin-aldosterone axis and abnormal renal tubular function remains to be determined. In view of reports of cardiovascular toxicity after treatment for germ-cell tumors, and evidence individually linking both magnesium deficiency and increased plasma renin activity (PRA) to cardiovascular consequences, these abnormalities in renin and magnesium metabolism suggest that patients treated with cisplatin-based chemotherapy should be carefully observed for the development of delayed cardiovascular toxicities.
