Abstrakt: | Objective: The role of the incretin hormones in the pathophysiology of maturity onset diabetes of the young (MODY) is unclear. Design: We studied the postprandial plasma responses of glucagon, incretin hormones (glucagon-like peptide 1 (GLP1) and glucose-dependent insulinotropic polypeptide (GIP)) and dipeptidyl-peptidase 4 (DPP4) enzymatic activity in patients with glucokinase (GCK) diabetes (MODY2) and hepatocyte nuclear factor 1α (HNF1A) diabetes (MODY3) as well as in matched healthy individuals (CTRLs). Subjects and Methods: Ten patients with MODY2 (mean age ± S.E.M. 43 ± 5 years; BMI 24 ± 2 kg/m(2); fasting plasma glucose (FPG) 7.1 ± 0.3 mmol/l: HbA1c 6.6 ± 0.2%), ten patients with MODY3 (age 31 ± 3 years; BMI 24 ± 1 kg/m(2); FPG 8.9 ± 0.8 mmol/l; HbA1c 7.0 ± 0.3%) and ten CTRLs (age 40 ± 5 years; BMI 24 ± 1 kg/m(2); FPG 5.1 ± 0.1 mmol/l; HbA1c 5.3 ± 0.1%) were examined with a liquid test meal. Results: All of the groups exhibited similar baseline values of glucagon (MODY2: 7 ± 1 pmol/l; MODY3: 6 ± 1 pmol/l; CTRLs: 8 ± 2 pmol/l, P=0.787), but patients with MODY3 exhibited postprandial hyperglucagonaemia (area under the curve (AUC) 838 ± 108 min × pmol/l) as compared to CTRLs (182 ± 176 min × pmol/l, P=0.005) and tended to have a greater response than did patients with MODY2 (410 ± 154 min × pmol/l, P=0.063). Similar peak concentrations and AUCs for plasma GIP and plasma GLP1 were observed across the groups. Increased fasting DPP4 activity was seen in patients with MODY3 (17.7 ± 1.2 mU/ml) vs CTRLs (13.6 ± 0.8 mU/ml, P=0.011), but the amount of activity was similar to that in patients with MODY2 (15.0 ± 0.7 mU/ml, P=0.133). Conclusion: The pathophysiology of MODY3 includes exaggerated postprandial glucagon responses and increased fasting DPP4 enzymatic activity but normal postprandial incretin responses both in patients with MODY2 and in patients with MODY3.
