ACE and kidney disorder: A systematic review of efforts to optimize screening for renal disease in diabetics and the impact of treatment 66 demonstrated in the case of DMT2 that urinary excretion of albumin decreased by 21% (CI 95%= 7%-32%) in those with normoalbuminuria and by 27% (CI 95%= 15%-38%) in those with microalbuminuria after treatment with Angiotensin-converting enzyme inhibitors (ACEI) or with angiotensin receptor blockers (ARB II) compared with those who did not receive this treatment, although the response was highly varied (I2= 85% and 87% respectively).
