Alpha-1-antitrypsin (AAT) is the prototypic member of the serine protease inhibitor (serpin) superfamily of proteins, which has a major role in inactivating neutrophil elastase and other proteases to maintain protease-antiprotease balance. In this study, the serum AAT was measured using enzymatic assay in diabetic patients. The serum trypsin inhibitory capacity (s-TIC) was determined in 144 outpatients with uncontrolled insulin-dependent diabetes mellitus (n = 47) and Don-insulin dependent diabetes mellitus (n = 97). The s-TIC values were 1.960 +/- 0.399, 2.002 +/- 0.4304 and 2.867 +/- 0.395 mu mol/min/ml in IDDM, NIDDM and healthy subjects, respectively. The diabetics individual had a significantly lower s-TIC than controls (P < 0.0001). It was found that there was a negative correlation between the s-TIC and the duration of diabetes (r = -0.5420; P < 0.0001). There was no correlation between s-TIC and age of patients (P = 0.865). Thus, diabetes is associated with reduced trypsin inhibitory capacity of plasma. (c) 2006 Elsevier Ireland Ltd. All rights reserved.
