We measured urinary activity of leucine aminopeptidase (EC 3.4.11.2) and creatinine concentrations (Cr, in mmol) in samples of second morning urine from 25 healthy subjects and 59 non-insulin-dependent diabetic (NIDD) subjects. If NIDD subjects are grouped according to their Alb/Cr ratio into normoalbuminuria (group A, Alb/Cr < 2.8 mg/mmol), microalbuminuria (group B, Alb/Cr 2.8-26.8 mg/mmol), and macroalbuminuria (group C, Alb/Cr > 26.8 mg/mmol), LAP/Cr ratios in all three groups exceeded those for healthy age-matched controls. Moreover, this ratio was higher in group B than in group A. The value for LAP/Cr was clearly abnormal (i.e., exceeded the upper limit of normal, log normal + 2 SD, found in healthy subjects) in 44% of group A. In the first 10-year period Of NIDD, prevalance of abnormal LAP/Cr ratio was 61.3%, whereas that of microalbuminuria was 35.5%. We have also found a LAP/Cr ratio abnormality of 91% in group B. Evidently, LAP/Cr may be increased early in NIDD subjects and be a more sensitive predictor of incipient nephropathy than microalbuminuria.
