ABSTRACT
Objective To investigate effective dosage of ACEI in renoprotective effect in primary glomerular dieases.Method In 154 patients with primary glomerular diseases,we performed a 4 month therapy,including 40 cases with high or low doses of captopril and 51 cases with high or low doses of cilazapril and 45 cases with high low doses of enalapril,and 18 cases with amlodipine as control.Mean arterial pressure (MAP),uninary protein,urinary albumin excretion rate and renal function were measured at basis and after 1,2,3,4 month of therapy,and ACE gene polymorphism was determined in these patients.Result 1.There were no difference on ACE gene polymorphism and diet protein and diet salt among control group and different ACEIs group;2.The antiproteinuria and the effect on renal function were same between patients with high and low dose of different ACEIs.Conclusion The low dose of ACEI has the same renoprotective effect as general dose in primary glomerular diseases.
