The known effects of the incretin hormone glucagon-like peptide-1 (GLP-1) on the metabolism are stimulation of insulin secretion, inhibition of glucagon secretion and hepatic glucose production, reduction in gastric emptying and modulation of the appetite. T2DM have disturbances in this system, providing a rationale for therapeutic use of GLP-1 in T2DM. Furthermore, GLP-1 seems to exert trophic effects on the beta-cell.\n\nDipeptidyl Peptidase IV (DPP-IV) inhibitors represent a new class of oral anti-hyperglycemic agents for the treatment of T2DM. The therapeutic utility of these antihyperglycemic agents rests on their ability of to increase active (intact) levels of incretin peptides, including GLP-1 and GIP.\n\nTwenty four T2DM volunteers will be evaluated by a meal tolerance test (MTT) for incretin hormone measurements, and by the hyperglycemic clamp followed by an arginine test for assessing the beta-cell function and the acute insulin response. Others parameters as body composition and basic biochemistry will be also evaluated at Laboratory of Investigation on Metabolism and Diabetes - LIMED / State university of Campinas, Brazil.\n\nT2DM in elderly are behaving differently. Elderly patients have no increase in liver production of glucose; when obese, have normal insulin secretion, however, display extreme resistance to its action. In non obese individuals, the concentration of glucose necessary for insulin secretion is increased and the action is standard. These findings suggest therefore that the approach should be differentiated treatment for these individuals.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '35 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Adult Type 2 Diabetes subjects', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Stable weight (\\<5% variation) within the last three months\n* Age: 35 to 50 years old for middle-age group, and 65 to 80 y old for elderly group\n* Body mass index (BMI): 20 to 29.9kg/m2\n* T2DM with diagnosis above 35 years and less than 5 years (Middle-age group)\n* T2DM with diagnosis above 65 years and less than 5 years (Elderly group)\n* Use of oral antidiabetic drugs (that must at stable dose within the last 3 months)\n* Not have participated in any study of intervention with drugs in the last six months.\n\nExclusion Criteria:\n\n* Use of estrogen, progestogen, active antipsychotics and systemic corticosteroids\n* Use of DPP-IV inhibitors and incretin mimetics (current or within 1 month before)\n* Continuous use of insulin or glitazone\n* Hepatic cirrhosis, renal failure or any clinical condition with impaired insulin sensitivity\n* Smoking\n* Obesity\n* Uncontrolled systemic or disabling diseases\n* T2DM treated by non pharmacological methods\n* Patients submitted to bariatric surgery\n* Latent autoimmune diabetes of the adult (positive anti-GAD antibodies)'}, 'identificationModule': {'nctId': 'NCT00843232', 'briefTitle': 'Characterization of the Incretinpathy in Type 2 Diabetes Initiated After Sixty Years Old', 'organization': {'class': 'OTHER', 'fullName': 'University of Campinas, Brazil'}, 'officialTitle': 'Physiopathology of Type 2 Diabetes Initiated After Sixty Years Old: Characterization of a Diabetic-related Incretinpathy in Aging Subjects.', 'orgStudyIdInfo': {'id': 'LIMED0007'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Elderly T2DM', 'description': 'Elderly T2DM subjects 65 to 80 years old'}, {'label': 'Middle-age T2DM', 'description': 'Middle-age T2DM subjects 35 to 50 years old'}]}, 'contactsLocationsModule': {'locations': [{'city': 'Campinas', 'state': 'São Paulo', 'country': 'Brazil', 'facility': 'LIMED (Laboratory of Investigation of Metabolism and Diabetes)/GASTROCENTRO/Univeristy of Campinas (UNICAMP)', 'geoPoint': {'lat': -22.90556, 'lon': -47.06083}}], 'overallOfficials': [{'name': 'Bruno Geloneze, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'LIMED (Laboratory of Investigation of Metabolism and Diabetes)/GASTROCENTRO/Univeristy of Campinas (UNICAMP)'}, {'name': 'José Carlos Pareja, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'LIMED (Laboratory of Investigation of Metabolism and Diabetes)/GASTROCENTRO/Univeristy of Campinas (UNICAMP)'}, {'name': 'Carla Fiori, Nurse', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'LIMED (Laboratory of Investigation of Metabolism and Diabetes)/GASTROCENTRO/Univeristy of Campinas (UNICAMP)'}, {'name': 'Marcelo MO Lima, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'LIMED (Laboratory of Investigation of Metabolism and Diabetes)/GASTROCENTRO/Univeristy of Campinas (UNICAMP)'}, {'name': 'Ana Carolina Vasques, MSNutr', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'LIMED (Laboratory of Investigation of Metabolism and Diabetes)/GASTROCENTRO/Univeristy of Campinas (UNICAMP)'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Campinas, Brazil', 'class': 'OTHER'}, 'responsibleParty': {'oldNameTitle': 'Bruno Geloneze', 'oldOrganization': 'University of Campinas, Brazil'}}}, 'annotationSection': {'annotationModule': {'unpostedAnnotation': {'unpostedEvents': [{'date': '2011-10-04', 'type': 'RELEASE'}, {'date': '2011-11-13', 'type': 'RESET'}, {'date': '2012-06-17', 'type': 'RELEASE'}, {'date': '2012-07-19', 'type': 'RESET'}, {'date': '2013-03-07', 'type': 'RELEASE'}, {'date': '2013-04-19', 'type': 'RESET'}], 'unpostedResponsibleParty': 'Bruno Geloneze, Dr. Bruno Geloneze, University of Campinas, Brazil'}}}}
