Abstract:
To investigate the effect of high-dose cisplatin (40 mg/m2 daily for 5 days), 51Cr-EDTA clearance was used as a measure of glomerular filtration rate (GFR). 51Cr-EDTA clearance decreased significantly from 109 +/- 3 ml/min * 1.73 m2 to 68 +/- 3 ml/min * 1.73 m2 after three cycles of cisplatin and remained at this decreased level during the observation period (24 months). To determine the reliability of creatinine as a measure of GFR, we compared the simultaneous clearance of creatinine to that of 51Cr-EDTA. A good correlation between 51Cr-EDTA clearance and creatinine clearance was observed before and 3 months after termination of treatment, but no correlation was found during treatment. S-creatinine decreased significantly during treatment, probably due to muscle wasting. We conclude that s-creatinine and creatinine clearance are unsuitable measures of glomerular function during high-dose cisplatin treatment. All patients developed proteinuria during treatment. The changes in clearance ratios of beta-2-microglobulin/albumin and IgG/albumin show that the proteinuria observed during cisplatin infusion is predominantly of tubular origin, whereas the proteinuria between the treatment periods is mainly of glomerular origin.

Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
