Captopril can not Block the Effects of Steroids on Glomerular Membrane Permeability

The objective of the study was to observe whether the angiotensin-converting enzyme inhibitor capto-pril can block the effects of steroids or not,and to research the relationship between the effects of steroids and the activity of renin-angiotensin-aldosterone system. Method: Fifteen nephrotic patients were enrolled in group A. Urinary protein excretion rate (UPro) and the percentage of low, medium and high molecular proteins were analysed before and after the administration of prednison( 1mg/kg). Fourteen nephrotic patients were enrolled in group B and the same markers were observed before and after the administration of prednison (1mg/kg)and captopril(50mg). Results: The results of both group A and B were the same. When captopril and/or prednison were administered, UPro and high molecular urinary protein were increased significantly, while the low molecular protein was decreased significantly. Conclusion: Captopril can not block the effects of steroids on glomerular membrane permeability. The effects of steroids on glomerular membrane permeability had hardly any relationship with the activity of the renin-angiotensin-aldosterone system of the kidney.
