Hypoglycémie et traitement du diabète de type 2. Le retour à une normoglycémie n'est pas nécessairement la meilleure stratégie thérapeutique [Hypoglycemia and diabetes treatment: the return to normal glucose level is not always the best therapeutic strategy].

Recent clinical trials with type 2 diabetic patients and the quest of normal glyceamic values, have revealed difficulties and limitations. These too normal glyceamic targets corresponding to the physiological standards are associated with very high rate of hypoglycemia and an increase of mortality. A too simplistic view of treatment: "the lowest, the better is in the diabetes" is no longer defensible. The knowledge from complex systems behavior invites us to search targets adapted to a new state of equilibrium due to loss of self-regulation. These targets should not aim the physiological standards but to be adapted to patient's situation. Shared decision-making and consensus are the two pillars of this new strategy supported by the new ADA-EASD guidelines.

Structural alterations of the coronary arterial wall are associated with myocardial flow heterogeneity in type 2 diabetes mellitus.

PURPOSE: To determine the relationship between carotid intima-media thickness (IMT), coronary artery calcification (CAC), and myocardial blood flow (MBF) at rest and during vasomotor stress in type 2 diabetes mellitus (DM). METHODS: In 68 individuals, carotid IMT was measured using high-resolution vascular ultrasound, while the presence of CAC was determined with electron beam tomography (EBT). Global and regional MBF was determined in milliliters per gram per minute with (13)N-ammonia and positron emission tomography (PET) at rest, during cold pressor testing (CPT), and during adenosine (ADO) stimulation. RESULTS: There was neither a relationship between carotid IMT and CAC (r = 0.10, p = 0.32) nor between carotid IMT and coronary circulatory function in response to CPT and during ADO (r = -0.18, p = 0.25 and r = 0.10, p = 0.54, respectively). In 33 individuals, EBT detected CAC with a mean Agatston-derived calcium score of 44 +/- 18. There was a significant difference in regional MBFs between territories with and without CAC at rest and during ADO-stimulated hyperemia (0.69 +/- 0.24 vs. 0.74 +/- 0.23 and 1.82 +/- 0.50 vs. 1.95 +/- 0.51 ml/g/min; p < or = 0.05, respectively) and also during CPT in DM but less pronounced (0.81 +/- 0.24 vs. 0.83 +/- 0.23 ml/g/min; p = ns). The increase in CAC was paralleled with a progressive regional decrease in resting as well as in CPT- and ADO-related MBFs (r = -0.36, p < or = 0.014; r = -0.46, p < or = 0.007; and r = -0.33, p < or = 0.041, respectively). CONCLUSIONS: The absence of any correlation between carotid IMT and coronary circulatory function in type 2 DM suggests different features and stages of early atherosclerosis in the peripheral and coronary circulation. PET-measured MBF heterogeneity at rest and during vasomotor stress may reflect downstream fluid dynamic effects of coronary artery disease (CAD)-related early structural alterations of the arterial wall.

Avaliação de dois esquemas de monitorização domiciliar em pacientes com diabetes mellitus do tipo 1

O estudo teve por objetivo avaliar a efetividade de esquemas de monitorização domiciliar sangüíneo e urinário, na obtenção de adequado controle glicêmico, em pacientes com diabetes mellitus do tipo 1, em regime quinzenal de ajuste terapêutico; durante 6 meses de participação em grupos educativos. A amostra foi de 34 pacientes divididos em dois grupos. Os pacientes do grupo A realizaram monitorização domiciliar da glicemia capilar 1 vez ao dia e os do grupo B realizaram monitorização domiciliar da glicosúria 1 vez ao dia, conforme esquemas preconizados. Estes esquemas possibilitaram construção de perfis e de ajustes terapêuticos. Os resultados mostraram que o uso sistemático dos testes domiciliares sangúíneos e urinários da forma prescrita, não proporcionou melhora significante no controle metabólico em nenhum dos dois grupos. Entretanto, favoreceu o processo educativo e possibilitou reflexões sobre a necessidade de intensificação da monitorização glicêmica.

Caracterização dos perfis glicêmicos domiciliares como estratégia para os ajustes insulinoterápicos em pacientes com diabetes mellitus do tipo 1

O artigo tem como objetivo principal caracterizar os perfis glicêmicos domiciliares de pacientes com diabetes mellitus tipo1, a partir de um esquema de monitorização proposto, e adotá-los como estratégia de ajuste nas doses de insulina. Foram realizados 3259 testes, 781 antes do café, 752 antes do almoço, 765 antes do jantar, 740 antes de deitar e 221 pela madrugada. A média das glicemias nestes períodos ultrapassaram os limites superiores satisfatórios em 6,87%, 3,83%, 11,37%, 30,50% e 19,28% respectivamente. Estes dados forneceram subsídios para ajustes nos esquemas insulinoterápicos. Os níveis HbA1c não mudaram de forma significante com os ajustes realizados porém, foram mantidos em 10%.

Managing diabetes in Switzerland : a systemic approach

Executive summaryThe increasing prevalence of chronic diseases is one of the major causes of rising health expenditure, as stated by the WHO. Not only chronic diseases are very costly, but they are by far the leading cause of mortality in the world, representing 60% of all deaths. Diabetes in particular is becoming a major burden of disease. In Switzerland around 5% of the population suffer of type 2 diabetes and 5 to 10% of the annual health care budget is attributable to diabetes. If the predictions of WHO do realise, the prevalence of diabetes will double until 2030 and so is expected the attributable health expenditure.The objective of this thesis is to provide policy recommendations as to slow down the disease progression and its costly complication. We study the factors that influence diabetes dynamics and the interventions that improve health outcomes while decreasing costs according to different time horizon and use systems thinking and system dynamic.Our results show that managing diabetes requires using integrated care interventions that are effective on three fronts: (1) delaying the onset of complications, (2) slowing down the disease progression and (3) accelerating the time to diagnosis of diabetes and its complications. We recommend firstly the implementation of those interventions targeted at changing patients' behaviour which are also less expensive, but require a change in the delivery of care and medical practices. Then policies targeted at an earlier diagnosis of diabetes, its prevention and the diagnosis of complications are to be considered. This sequence of interventions allows saving money, as total costs decrease, even including the costs of interventions and result in longer life expectancy of diabetics in the long term.In diabetes management there is therefore a trade-off between medical costs and patients' benefits on the one hand and between the objectives of obtaining results in the short or long term on the other hand. Decision makers need to deliver acceptable outcomes in the short term. Considering this criterion, the preferred policy may be to focus only on diagnosed diabetics, thus attempting to slow down the progression of their disease, compared to an integrated care approach addressing all the aspects of the disease. Such a policy also yields desirable results in terms of costs and patients' benefits.

Postmortem diagnosis of unsuspected diabetes mellitus.

Vitreous glucose, blood beta-hydroxybutyrate and glycated hemoglobin were systematically measured in a series of 500 medico-legal autopsies in order to characterize the glycemic control during the weeks preceding death and identify ketoacidosis as the cause of death in diagnosed and unsuspected diabetics. Unenhanced CT-scans, histology and toxicology were performed in all cases. 16 cases of diabetic ketoacidosis were identified based on the results of all investigations. Among those, 13 cases concerned individuals with pre-existing diagnoses of diabetes mellitus whereas 3 cases concerned individuals with undiagnosed diabetes. A recent cocaine use was observed in 2 cases. C-reactive protein, interleukin-6 and interleukin-10 were measured and proved to be increased in all cases of diabetic ketoacidosis, whereas markers of generalized, bacterial infection and sepsis were normal in most of these cases. The results of this study highlight the usefulness of systematically performing biochemistry to identify ketoacidosis in unsuspected diabetics. It also emphasizes the role of toxicology and biochemistry to support the diagnosis of diabetic ketoacidosis and delineate the pathophysiological mechanisms that may disrupt the metabolic balance and finally lead to death in diabetic individuals.

Association of smoking and nicotine dependence with pre-diabetes in young and healthy adults.

INTRODUCTION: Several studies have shown an increased risk of type 2 diabetes among smokers. Therefore, the aim of this analysis was to assess the relationship between smoking, cumulative smoking exposure and nicotine dependence with pre-diabetes. METHODS: We performed a cross-sectional analysis of healthy adults aged 25-41 in the Principality of Liechtenstein. Individuals with known diabetes, Body Mass Index (BMI) >35 kg/m² and prevalent cardiovascular disease were excluded. Smoking behaviour was assessed by self-report. Pre-diabetes was defined as glycosylated haemoglobin between 5.7% and 6.4%. Multivariable logistic regression models were done. RESULTS: Of the 2142 participants (median age 37 years), 499 (23.3%) had pre-diabetes. There were 1,168 (55%) never smokers, 503 (23%) past smokers and 471 (22%) current smokers, with a prevalence of pre-diabetes of 21.2%, 20.9% and 31.2%, respectively (p <0.0001). In multivariable regression models, current smokers had an odds ratio (OR) of pre-diabetes of 1.82 (95% confidential interval (CI) 1.39; 2.38, p <0.0001). Individuals with a smoking exposure of <5, 5-10 and >10 pack-years had an OR (95% CI) for pre-diabetes of 1.34 (0.90; 2.00), 1.80 (1.07; 3.01) and 2.51 (1.80; 3.59) (p linear trend <0.0001) compared with never smokers. A Fagerström score of 2, 3-5 and >5 among current smokers was associated with an OR (95% CI) for pre-diabetes of 1.27 (0.89; 1.82), 2.15 (1.48; 3.13) and 3.35 (1.73; 6.48) (p linear trend <0.0001). DISCUSSION: Smoking is strongly associated with pre-diabetes in young adults with a low burden of smoking exposure. Nicotine dependence could be a potential mechanism of this relationship.
