Hyperglycaemia increases dipeptidyl peptidase IV activity in diabetes mellitus
Aims/hypotheses Chronic hyperglycaemia increases dipeptidyl peptidase IV (DPP-IV) activity in endothelial cells in vitro. The present study was designed to assess the effect of high glucose on circulating DPP-IV activity in patients with type 1 and type 2 diabetes. Methods Plasma DPP-IV activity was...

520 | |a Aims/hypotheses Chronic hyperglycaemia increases dipeptidyl peptidase IV (DPP-IV) activity in endothelial cells in vitro. The present study was designed to assess the effect of high glucose on circulating DPP-IV activity in patients with type 1 and type 2 diabetes. Methods Plasma DPP-IV activity was measured in 29 patients with type 1 diabetes and 29 age-, sex- and BMI-matched control subjects. We also assessed DPP-IV activity in 31 type 2 diabetic patients with $ HbA_{1} $c >8.5% and in plasma from matched groups of 31 newly diagnosed diabetic subjects with $ HbA_{1} $c <7.5%, 31 subjects with IGT and 62 subjects with NGT. In a further sample of 66 type 2 diabetic patients, a longitudinal study was also performed to evaluate variations in DPP-IV activity and $ HbA_{1} $c over 3 months. Results DPP-IV activity in type 1 diabetic patients was not significantly different from that in control subjects; however, a significant correlation between DPP-IV and $ HbA_{1} $c was observed in diabetic subjects (r=0.47; p<0.01). Type 2 diabetic patients with $ HbA_{1} $c >8.5% showed significantly (p<0.05) higher DPP-IV activity (mean±SD 27.7±7.1 U/l) than newly diagnosed diabetic patients and subjects with IGT (22.1±6.0 and 18.8±8.8 U/l, respectively). Variations in DPP-IV activity over 3 months in type 2 diabetic patients showed a significant positive correlation with variations in $ HbA_{1} $c (r=0.26; p<0.05). Conclusions/interpretation Chronic hyperglycaemia induces a significant increase in DPP-IV activity in type 1 and type 2 diabetes. This phenomenon could contribute to the reduction in circulating active glucagon-like peptide-1 and to the consequent postprandial hyperglycaemia in type 2 diabetic patients with poor metabolic control. | ||

The present study was designed to assess the effect of high glucose on circulating DPP-IV activity in patients with type 1 and type 2 diabetes. Methods Plasma DPP-IV activity was measured in 29 patients with type 1 diabetes and 29 age-, sex- and BMI-matched control subjects. We also assessed DPP-IV activity in 31 type 2 diabetic patients with $ HbA_{1} $c >8.5% and in plasma from matched groups of 31 newly diagnosed diabetic subjects with $ HbA_{1} $c <7.5%, 31 subjects with IGT and 62 subjects with NGT. In a further sample of 66 type 2 diabetic patients, a longitudinal study was also performed to evaluate variations in DPP-IV activity and $ HbA_{1} $c over 3 months. Results DPP-IV activity in type 1 diabetic patients was not significantly different from that in control subjects; however, a significant correlation between DPP-IV and $ HbA_{1} $c was observed in diabetic subjects (r=0.47; p<0.01). Type 2 diabetic patients with $ HbA_{1} $c >8.5% showed significantly (p<0.05) higher DPP-IV activity (mean±SD 27.7±7.1 U/l) than newly diagnosed diabetic patients and subjects with IGT (22.1±6.0 and 18.8±8.8 U/l, respectively). Variations in DPP-IV activity over 3 months in type 2 diabetic patients showed a significant positive correlation with variations in $ HbA_{1} $c (r=0.26; p<0.05). Conclusions/interpretation Chronic hyperglycaemia induces a significant increase in DPP-IV activity in type 1 and type 2 diabetes. This phenomenon could contribute to the reduction in circulating active glucagon-like peptide-1 and to the consequent postprandial hyperglycaemia in type 2 diabetic patients with poor metabolic control.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Diabetes mellitus</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Dipeptidyl peptidase IV</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pala, L.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ciani, S.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bardini, G.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pezzatini, A.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sposato, I.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cremasco, F.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ognibene, A.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rotella, C.

Hyperglycaemia increases dipeptidyl peptidase IV activity in diabetes mellitus |
abstract |
Aims/hypotheses Chronic hyperglycaemia increases dipeptidyl peptidase IV (DPP-IV) activity in endothelial cells in vitro. The present study was designed to assess the effect of high glucose on circulating DPP-IV activity in patients with type 1 and type 2 diabetes. Methods Plasma DPP-IV activity was measured in 29 patients with type 1 diabetes and 29 age-, sex- and BMI-matched control subjects. We also assessed DPP-IV activity in 31 type 2 diabetic patients with $ HbA_{1} $c >8.5% and in plasma from matched groups of 31 newly diagnosed diabetic subjects with $ HbA_{1} $c <7.5%, 31 subjects with IGT and 62 subjects with NGT. In a further sample of 66 type 2 diabetic patients, a longitudinal study was also performed to evaluate variations in DPP-IV activity and $ HbA_{1} $c over 3 months. Results DPP-IV activity in type 1 diabetic patients was not significantly different from that in control subjects; however, a significant correlation between DPP-IV and $ HbA_{1} $c was observed in diabetic subjects (r=0.47; p<0.01). Type 2 diabetic patients with $ HbA_{1} $c >8.5% showed significantly (p<0.05) higher DPP-IV activity (mean±SD 27.7±7.1 U/l) than newly diagnosed diabetic patients and subjects with IGT (22.1±6.0 and 18.8±8.8 U/l, respectively). Variations in DPP-IV activity over 3 months in type 2 diabetic patients showed a significant positive correlation with variations in $ HbA_{1} $c (r=0.26; p<0.05). Conclusions/interpretation Chronic hyperglycaemia induces a significant increase in DPP-IV activity in type 1 and type 2 diabetes. This phenomenon could contribute to the reduction in circulating active glucagon-like peptide-1 and to the consequent postprandial hyperglycaemia in type 2 diabetic patients with poor metabolic control. © Springer-Verlag 2005 |
