Effect of camostat mesilate for the treatment of advanced diabetic nephropathy.

Abstract

Camostat mesilate is a developed derivative of gabexate mesilate for oral administration and is known to be one of the most potent protease inhibitors. We administered this drug to 15 patients with advanced diabetic nephropathy at a daily dose of 600 mg for 4 to 6 weeks. All patients had been treated with conventional therapy including angiotensin-converting enzyme inhibitors, and their diseases had stabilized for at least 2 weeks before the camostat mesilate therapy. Urinary protein excretion decreased promptly from 4.8 +/- 0.6 to 2.9 +/- 0.4 gm/day (mean +/- SEM, p less than 0.01) and serum albumin level increased from 2.7 +/- 0.2 gm/dl to 2.9 +/- 0.2 gm/dl (mean +/- SEM, p less than 0.05) within 4 to 6 weeks. The amount of plasma fibrinogen significantly decreased from 419.7 +/- 42.3 mg/dl to 306.6 +/- 28.3 mg/dl (mean +/- SEM, p less than 0.01), and urinary total fibrinogen degradation product excretion over 24 hours also decreased from 26,118 +/- 9,696 to 18,072 +/- 7,107 micrograms/day (mean +/- SEM, p less than 0.05). The value for serum creatinine level did not change during this intervention. We suggest that camostat mesilate suppresses the hypercoagulable state originating from diabetes mellitus, and changes the permselectivity of the glomerular capillary wall. These effects of camostat mesilate may improve the prognosis of diabetic nephropathy.
