Abstract

The immediate renal response to large intravenous doses of prednisolone was studied in 18 kidney homograft recipients and in 6 normal subjects. Clearance rates of inulin (C IN ), creatinine (C CR ), p-aminohippurate (C PAH ), and electrolytes were measured over 3 one-hour periods following intravenous infusion of prednisolone (1 Gm.) and compared with corresponding clearance rates after a placebo infusion. C IN , C CR , and C PAH rates and ( C CR C IN ) ratios exhibited a substantial decrease during all collection periods following the infusion of prednisolone, both in the normal subjects and in the patients. Fractional excretion of potassium ( C K C IN ) increased in a progressive fashion reaching peak values after 3 hours. Biphasic variations were observed in the fractional excretion of sodium ( C NA C IN ); an increase during the first hour was followed by a decrease during the third hour. The changes in the fractional excretions of ultrafiltrable calcium ( C Ca C IN ), ultrafiltrable magnesium ( C Mg C IN ), and phosphorus ( C P C IN ) were minimal. Normal subjects exhibited significant decreases in ( C Ca C IN ) and ( C Mg C IN ) following the infusion of prednisolone; there was no significant change in the patients. ( C P C IN ) increased significantly both in the normal subjects and in the patients. These results indicate that acute suppression of kidney function is a general renal response to large doses of glucocorticoids. The marked decrease in the creatinine clearance ratio ( C CR C IN ) observed after the administration of prednisolone is consistent with a depressed tubular secretion of creatinine and emphasizes the inadequacy of c CR as an indication of glomerular filtration rate (GFR) under conditions in which large doses of glucocorticoids are employed. © 1971.
