BACKGROUND AND METHODS Non-insulin-dependent diabetes mellitus (NIDDM) is a genetically heterogeneous disorder. Maturity-onset diabetes of the young, a form of NIDDM with an early age of onset and autosomal dominant inheritance, can result from mutations in glucokinase, a key enzyme of glucose metabolism in beta cells and the liver. We studied 32 French(More)
Paraoxonase is a high-density-lipoprotein-associated enzyme capable of hydrolysing lipid peroxides. Thus it might protect lipoproteins from oxidation. It has two isoforms, which arise from a glutamine (A isoform) to arginine (B isoform) interchange at position 192. The relevance of this polymorphism to coronary heart disease (CHD) in non-insulin-dependent(More)
Paraoxonase was identified as a genetic risk factor for cardiovascular disease (CVD) in recent studies focusing on a polymorphism affecting position 191. A second polymorphism of the paraoxonase gene affects position 54 and involves a methionine (M allele) to leucine (L allele) change. It was investigated in diabetic patients (n = 408) with and without(More)
Maturity-onset diabetes of the young (MODY) is a form of non-insulin-dependent (type 2) diabetes mellitus (NIDDM) which is characterized by an early age at onset and an autosomal dominant mode of inheritance. Except for these features, the clinical characteristics of patients with MODY are similar to those with the more common late-onset form(s) of NIDDM.(More)
OBJECTIVE Self monitoring of blood glucose (SMBG) in type 2 diabetes is a topic of current interest (imbalance between increased health-care costs and improvement in compliance with treatment and diet). An open label randomized prospective study was designed to compare changes in metabolic control over 6 months in patients managed with usual recommendations(More)
To study if self-monitoring of glucose, urinary or capillary, could help them to improve their metabolic control through better compliance to diet and/or hypoglycaemic agents, 208 non-insulin-treated poorly controlled diabetic patients were randomized to: group A--regular HbA1c determinations but no self-monitoring, group B--self-urine glucose monitoring,(More)
Estimates and projections suggest an epidemic expansion of diabetes incidence and prevalence in Europe. To evaluate trends in type 1 and type 2 diabetes in seven European countries (Finland, Denmark, the UK, Germany, France, Spain, and Italy), a variety of information is available, including population-based studies on small or large cohorts of subjects(More)
OBJECTIVE To investigate whether a low dose of the angiotensin converting enzyme (ACE) inhibitor ramipril lowers cardiovascular and renal events in patients with type 2 diabetes who have microalbuminuria or proteinuria. DESIGN Randomised, double blind, parallel group trial comparing ramipril (1.25 mg/day) with placebo (on top of usual treatment) for(More)
Mutations in the glucokinase gene are a major cause of maturity-onset diabetes of the young. To evaluate the contribution of this gene to the development of late-onset NIDDM, linkage analyses between DNA polymorphisms at the glucokinase locus and NIDDM were performed in 79 multigenerational French families. In addition, all exons and the islet promoter(More)
The serum enzyme paraoxonase (PON) protects LDLs from oxidative stress. We recently identified promoter polymorphisms of the PON gene that strongly affect gene expression and serum levels of the enzyme. The present study tested the hypothesis that promoter polymorphism T(-107)C could be a risk factor for vascular disease in type 2 diabetic patients by(More)
