Aging is a complex, multifactorial and continuous process involving physical and biological modifications such as a notably decrease in glucose tolerance and type 2 diabetes risk. Insulin sensitivity follow-up during aging is difficult mainly because of many confounding factors (environment, lifestyle).\n\nIn 2006, SUVIMAX 2 study began, based on the monitoring of volunteers who participated in former SUVIMAX study (1994-2003). This study was a randomised trial which was designed to study the link between a low antioxidant intake and risk of cancer or ischemic heart disease. The subjects recently had a health check-up including complete information about their diet, physical and neurosensory status. Based on these data, a score was established to classify subjects according to their quality of aging ("successful aging versus "problematic aging") These volunteers, who undertook a 13-year follow-up (dietary and medical status), constitute the reference population to determine the mechanisms involved in the insulin resistance development in aging.\n\nThe purpose of our research work is to determine whether the quality of aging could influence insulin sensitivity, by studying metabolic profile and change in gene expression (genes involved in glucose metabolism and metabolic senescence in muscle tissue) during aging.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '60 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Volunteers from the cohort aging SUVIMAX 2\n* Men and Women\n* over 60 years\n* BMI between 18 and 35 kg/m2 (including terminals)\n* Normal medical check up\n* Blood pressure \\< 140/90 mmHg\n* Normal glycemia, lipid profile\n* sedentary or moderate physical activity (maximum 4 hours per week)\n\nExclusion Criteria:\n\n* Biological results or anormal chek-up\n* medical or surgical history not compatible with study\n* severe digestive, cardiovascular, renal, liver or tumor disorders history in the 5 last years\n* infectious or inflammatory disease within 2 months\n* surgical history within 3 months\n* bood donation within 2 months\n* coagulation disease, anticoagulant or antiplatelet agents (aspirin ...) treatment\n* xylocaïn allergy\n* claustrophobia\n* Drug that could affect insulin sensitivity (beta blockers, lipid lowering, oral antidiabetics, insulin, , steroids)'}, 'identificationModule': {'nctId': 'NCT00951392', 'acronym': 'COMPALICLAMP', 'briefTitle': 'Implication of Metabolic and Genomic Modifications in Elderly Subjects', 'organization': {'class': 'OTHER', 'fullName': 'Hospices Civils de Lyon'}, 'officialTitle': 'Implication of Metabolic and Genomic Modifications in Elderly Subjects', 'orgStudyIdInfo': {'id': '2008.547'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Problematic aging', 'interventionNames': ['Drug: euglycemic hyperinsulinemic clamp', 'Procedure: muscle biopsy', 'Device: indirect calorimetry']}, {'type': 'EXPERIMENTAL', 'label': 'successful aging', 'interventionNames': ['Drug: euglycemic hyperinsulinemic clamp', 'Procedure: muscle biopsy', 'Device: indirect calorimetry']}], 'interventions': [{'name': 'euglycemic hyperinsulinemic clamp', 'type': 'DRUG', 'description': 'Insulin perfusion at 1 mU.kg-1.min-1\n\nGlucose perfusion to maintain euglycemia at 5,0 ± 0,5 mmol/l\n\nBlood tests', 'armGroupLabels': ['Problematic aging', 'successful aging']}, {'name': 'muscle biopsy', 'type': 'PROCEDURE', 'description': 'Gene expression in muscle tissue will be studied with two approaches :\n\n* Candidate gene approach by quantitative RT-PCR : genes involved in the carbohydrates and lipids metabolism including lipid oxidation in muscle (lipid carriers, PPARs), expression of 7 sirtuins isoforms as well as some of their target genes (NFkB, PGC1a)\n* Global transcriptome analysis by DNA Chip', 'armGroupLabels': ['Problematic aging', 'successful aging']}, {'name': 'indirect calorimetry', 'type': 'DEVICE', 'description': 'energy expenditure measurement', 'armGroupLabels': ['Problematic aging', 'successful aging']}]}, 'contactsLocationsModule': {'locations': [{'zip': '69495', 'city': 'Pierre-Bénite', 'country': 'France', 'facility': 'Centre de recherche en nutrition humaine Rhône-Alpes', 'geoPoint': {'lat': 45.70359, 'lon': 4.82424}}], 'overallOfficials': [{'name': 'Martine LAVILLE, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Centre de Recherche en Nutrition Humaine Rhône-Alpes'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Hospices Civils de Lyon', 'class': 'OTHER'}, 'responsibleParty': {'oldNameTitle': 'Martine Laville PhD, MD', 'oldOrganization': 'Hospices Civils de Lyon'}}}}
