Insulin initiation in type 2 diabetic patients admitted in hospital in France and follow-up at 1 year.

OBJECTIVES AND METHODS: The IDAHO 2 epidemiological survey was conducted in departments of diabetology in insulin-naïve type 2 diabetics for whom insulin was initiated. The objective was to assess the patients' profile, the treatments proposed during hospital stay and after one year. RESULTS: 797 patients were analysed. Their characteristics were: age 64+/-12 years, 49% males, weight: 78+/-17 kg, BMI: 29+/-6 kg/m2, diabetes duration 11 years, prevalence of complications: 68%, fasting blood glucose 13+/-6 mmol/l, HbA1c: 10+/-2.2%; treatment prior to insulin comprised: at least 2 OHA: 71% of cases, one: 21%, no OAD: 8%. At hospital discharge, 54% of the patients used basal insulin. After 1 year, 670 continued on insulin. The insulin initiation was accompanied by a decrease in the FBG level (baseline: 13+/-6 mmol/l; final: 8.5+/-2.75 mmol/l; P<0.0001) and a HbA1c improvement (baseline: 10+/-2.2%; final: 7.9+/-1.4%; P<0.0001). This was observed du-ring the first 6 months (HbA1c: 7.8%, P<0.0001 versus baseline). 80% of the patients remained on the same insulin regimen after 1 year: 35% had 1 injection/day, 44% had 2, 12% had 3 and 9% had a complex regimen. The weight gain, the final daily dose and hypoglycaemias increased with the number of injections. The mean daily insulin dose was 33 U/day (24 U with 1 injection/day). CONCLUSION: The IDAHO study shows that insulin is effective in type 2 diabetics however, management is inadequate with insulin therapy being initiated too late and at doses which are low after one year.

Evaluation of a screening program for diabetic retinopathy in a primary care setting Dodia (Dépistage ophtalmologique du diabète) study.

OBJECTIVES: The aim of this observational study was to evaluate the screening for diabetic retinopathy (DR) using eye fundus photography taken by a nonmydriatic camera and transmitted trough the Internet to an ophthalmological reading centre, as compared to a dilated eye examination performed by an ophthalmologist. METHODS: A total of 456 and 426 diabetic patients were included by two different groups of primary care physicians (PCPs), 358 being screened with the non-mydriatic camera (experimental group) and 320 with dilated eye fundus exam (control group). RESULTS: The proportion of screened patients for whom PCPs received a screening report within the 6-month follow-up period was 74,1% for the experimental group and 71,5% for the control group. Screening for DR was negative in 77,6% of patients with eye fundus photographs vs 89,6% with dilated eye examination. DR was diagnosed in 62 patients (17,3%) with eye fundus photographs versus 31 with dilated eye examination (10,4%). Referral to an ophthalmologist was required in 59 reports of patients with photographs (16.5%), 23 of them due to high grade DR. Finally, the non-mydriatic camera was found of little inconvenience by patients. CONCLUSION: The telemedical approach to DR screening proved to be effective in providing primary care practitioners with information about their patient's eye status. This screening method allowed to identify patients requiring prompt referral to the ophthalmologist for further complete eye examination. In conclusion, this study provided successful results of DR screening using fundus photography in primary care patients, and strongly supports the need to further extend this screening program in a larger number of French sites.

[Compliance with hormone replacement therapy in menopausal women: results of a two-year prospective French study comparing transdermal treatment with fixed oral combination therapy].

OBJECTIVES: To evaluate rates of continuation with hormone replacement therapy (HRT) at 2 years in 2 cohorts of female patients, one of which was treated with a set combination of oral oestradiol valerate and medroxyprogesterone acetate and the other with percutaneous 17 beta-oestradiol gel combined with an oral progestogen selected by the prescribing doctor. PATIENTS AND METHODS: A prospective, randomised, open study, including 885 patients followed for 2 years whose 477 were in the oral HRT cohort and 408 were in the dermal cohort. Randomisation was done by group with prescription of the selected HRT for the cohort. The 2 treatment groups were compared using chi(2) tests and Fisher's exact test for qualitative variables, Student's t test or Wilcoxon's test for qualitative variables and Kaplan-Meier survival curves for continuation of HRT, with comparisons using the log-rank test. The prognostic value of baseline parameters on subsequent continuation of HRT was studied using the Cox model (Wald test, odds ratio). RESULTS; Among the 885 treated patients, 711 received the HRT assigned to their cohort (382 in the oral HRT cohort, 329 in the dermal HRT cohort). After 2 years, 77.9% of the patients in the oral HRT cohort and 73.4% of the patients in the dermal HRT cohort were continuing to take their prescribed HRT (P = 0. 076): 37.9% of patients in the oral HRT cohort and 20.2% of patients in the dermal HRT cohort (P < 0.001) continued taking their treatment without any modification. CONCLUSION: Although there was no significant difference in the level of compliance in the 2 groups, it is nonetheless worth noting that the HRT compliance with a sequential fixed estroprogestogen combination was, in this trial, at least equal to that with the free combination of a transdermal estrogen and a progestogen whose nature, dosage and sequence duration are selected by the prescriber. On the other hand, treatment modifications occurred more frequently in the cutaneous HRT group, which is logical as free combination affords to adapt the treatment to each patient.

[Ionizing radiation and hyperplasia of the intimal matrix: current data and perspectives].

Vascular reconstruction (bypasses or endoluminal procedures) is still associated with a significant rate of restenosis. For restenosis, smooth muscular cells are the principal actor by their property to migrate, proliferate and secrete extra-cellular substance after their change of phenotype. A variety of pharmacological and mechanical strategies have been directed with limited success. Using ionizing radiation have been recently developed, aiming to reduce the cell proliferation and consecutive restenosis following vessel injury (anastomoses or angioplasty). We reviewed the use of radiations on animals, cellular action and recent clinical trials. Recent clinical trials confirm an effective action of using radiations for restenosis prevention. We reviewed methods of delivering radiations also drawback and consequences using these hopefully methods.

Gender differences in the relation between food cravings and mood in an adult community: Results from the fleurbaix laventie ville santé study.

OBJECTIVE: The aim of this survey was to study food cravings and its indulgence in community adults (538 women and 506 men) and to compare nutritional parameters, weight preoccupations, and weight history between cravers and noncravers. METHOD: Cravers experienced a strong urge to eat specific foods more than once a week during the past 6 months. Food intake was estimated by a 3-day food record. RESULTS: 28% of women and 13% of men were food cravers. Cravers, especially women, were more frequently concerned about their weight than noncravers. Energy intake during snacks was higher in cravers. Less than 40% of cravers reported being hungry when they experienced cravings. Women cravers indulged their cravings as often as men. They reported more frequently negative feelings, whereas men reported more frequently positive feelings. DISCUSSION: This study shows that food craving episodes are strongly associated with mood but in a different way in women and men.

Heart rate-lowering and -regulating effects of once-daily sustained-release diltiazem.

BACKGROUND: Epidemiologic evidence suggests that an elevated heart rate (HR) is an adverse and independent prognostic factor in arterial hypertension and other cardiovascular diseases. Although diltiazem is characterized as an HR-lowering calcium antagonist, no studies have quantified the magnitude of HR changes in patients with angina or hypertension. HYPOTHESIS: The study was undertaken to explore the magnitude of proportional HR reduction at varying levels of resting HR with the sustained-release formulation of diltiazem (SR diltiazem) at the usual clinical doses of 200 or 300 mg once daily. METHODS: This meta-analysis was conducted on six comparative double-blind studies including 771 patients with angina or hypertension in which SR diltiazem 200-300 mg once daily was compared either with placebo or with other agents known not to influence HR (angiotensin-converting enzyme inhibitors, diuretics). Sustained-release diltiazem decreases elevated baseline HR, with an increasing effect at higher initial rates. RESULTS: Multiple comparisons by baseline HR category showed a significant difference between both groups for baseline HR of 74-84 beats/min and > or = 85 beats/min (p = 0.001). Sustained-release diltiazem had no significant HR-decreasing effect on baseline HR < or =74 beats/min but appears to have a genuine regulating effect on HR: it reduces tachycardia without inducing excessive bradycardia. These findings are in contrast to those with dihydropyridine calcium antagonists, which tend to increase HR and have been associated with an adverse outcome in acute cardiovascular conditions. At the same time, there is evidence to suggest that HR-lowering calcium-channel blockers decrease cardiovascular event rates following myocardial infarction. CONCLUSION: When calcium antagonists are indicated for use in patients with angina or hypertension, an HR-lowering agent, that is, diltiazem rather than dihydropyridine, should be recommended.

Accumulation of triglyceride-rich lipoprotein in subjects with abdominal obesity: the biguanides and the prevention of the risk of obesity (BIGPRO) 1 study.

The present study represents a new insight into the Biguanides and the Prevention of the Risk of Obesity (BIGPRO) 1 study population at inclusion. This population, selected basically on the basis of a high waist-to-hip ratio (>/=0.95 for men and >/=0.80 for women), is supposed to represent a group of patients with insulin resistance. The present study was undergone to establish whether apolipoprotein C-III (apoC-III) and apolipoprotein E (apoE) associated with apo B (apoC-III LpB and apoE LpB, respectively), considered to be markers of remnant accumulation, play a role in the hypertriglyceridemia associated with insulin resistance and whether they are related to other biological abnormalities frequently observed in this syndrome. In this population, the concentration of the markers of remnant accumulation increases with triglyceride levels. Therefore, correlation studies were realized to assess the relative effect of insulin and the markers of remnant accumulation on triglyceride plasma level. As a first attempt, a simple correlation analysis revealed that insulin is positively related to the markers of remnant accumulation only in hypertriglyceridemic patients (triglycerides >/=1.7 mmol/L). To assess the independent contribution of these markers, insulin, and other parameters related to the plasma triglyceride concentration, a stepwise multiple regression analysis was run. Results revealed that insulin and the markers of remnant accumulation (specifically, apoE LpB) are independent contributors to the plasma triglyceride concentration. Markers of the endothelial damage, plasminogen activator inhibitor-1, tissue plasminogen activator, and von Willebrand factor, which are often increased in the case of insulin resistance, were tested for their correlation with the markers of remnant accumulation. Plasminogen activator inhibitor-1 is positively correlated with these markers only in hypertriglyceridemic male subjects. It is concluded that increased insulin levels found in insulin resistance syndrome are associated with an increased production of triglyceride-rich lipoproteins enriched in apoC-III and apoE. The accumulation of these remnants and/or their abnormal composition in apoC-III and apoE could be an explanation for the development of hypertriglyceridemia in this syndrome.

[Insulin sensitivity and ethnic groups].

Epidemiological surveys show a large variation of type 2 diabetes (DT2) prevalence from one country to another, suggesting ethnic discrepancies in insulin sensitivity. Many data seem to confirm this hypothesis. We will show them while concentrating on data provided by surveys performed in French-speaking countries. The mechanisms of the ethnic differences in insulin sensitivity are unclear and further insights are needed. More than genetic factors, environmental factors appear to be involved in the occurence of insulin resistance and DT2. The epidemic nature of obesity and subsequent DT2 in the world urges health authorities in each country to raise campaigns to promote changes in life style and nutritional habits before the announced pandemy of DT2 becomes reality.

Effects of clinical audit on the quality of care in patients with type 2 diabetes: results of the DIABEST pilot study.

OBJECTIVE: To improve the quality of diabetes care in general practice by the use of audit. MATERIAL AND METHODS: A prospective multicenter pilot study. Thirty-five groups of ten general practitioners (GPs) have been set up throughout France on a voluntary basis. These groups were led by a steering committee that includes a diabetologist and a GP. Each group established a consensus on healthcare standards and carried out 2 data collections over a 12-month period, with adoption of corrective measures between these 2 collections. RESULTS: 309 (90.4%) of the 342 practitioners completed the first data collection, assessing the management of 3,125 patients over a year. Less than half the groups have reached the 80% reference threshold for quality of care with regard to foot examination, microalbuminuria, ECG, fundoscopy and assessment of diet. The audit also found no intervention within one year in case of poor glucose control for 47% of patients, unsatisfactory quality of HbA(1c) measurement and insufficient resources for diet and education. 226 (66.1%) practitioners completed the second data collection assessing the management of 2,248 patients. Comparison between the two phases of the audit showed significant improvements for all the indicators of the process of care (p<0.001). Quality of HbA(1c) measurement and diet assessment by GPs progressed (p<0.01). Outcomes of care also improved with respect to the proportion of patients with HbA(1c)<=8% (p=0.007), fasting glycaemia<1.40 g/l (p=0.05) and SBP<140 mmHg (p=0.02). CONCLUSIONS: This pilot study confirms the feasibility of using clinical audit at the national level. It seems to be an effective measure to improve the management of patients with type 2 diabetes in primary care. It is intended that the large-scale DIABEST study will address this issue.

Responding to allegations of scientific misconduct: the procedure at the French National Medical and Health Research Institute.

Institutions in France are not yet well prepared to respond to allegations of scientific misconduct. Following a serious allegation in late 1997, INSERM, the primary organization for medical and health-related research in France, began to reflect on this subject, aided by scientists and jurists. The conclusions have resulted in establishing a procedure to be followed in cases of alleged misconduct, and also in reinforcing the application of good laboratory practices within each laboratory. Guidelines for authorship practices and scientific assessment must also be considered. Even though each institution must remain responsible for responding to allegations of scientific misconduct within its doors, INSERM would like to see national, European, and international co-ordination about the methods of such response.

Puberty-associated differences in total cholesterol and triglyceride levels according to sex in French children aged 10-13 years.

PURPOSE: To assess the relationships between lipid levels and sexual maturity, independently of age-related differences, and to investigate possible differences related to sexual maturity across the percentiles of the lipid distributions. METHODS: Fasting serum total cholesterol and triglyceride concentrations were measured in 6577 boys and 6605 girls, aged from 10 to 13 years, with different Tanner stages. The total cholesterol and triglyceride mean and percentile levels were estimated according to age and Tanner stage by ordinary least squares and percentile regression models, separately in both sexes. RESULTS: In boys and girls, total cholesterol levels were significantly associated with pubertal stage after controlling for age. At age 12, the estimated mean levels in boys varied from 4.82 mmol/L for Tanner 1 to 4.41 for Tanner 5. The corresponding values were 5.05 and 4.62 mmol/L in girls, for whom the association with maturity was stronger in the upper than in the lower percentiles (p < 0.0001); between the extreme Tanner stages, the 95th percentiles of total cholesterol differed by 0.80 mmol/L, in comparison to 0.19 mmol/L for the 5th percentiles. Therefore, 1. 8% of girls and 0.7% of boys were classified differently whether Tanner stage was used or not to assess hypercholesterolemia (concentrations in the upper 5% of the distributions). Triglycerides were positively related to sexual maturity independently of age, but the discrepancies between classifications were lower; 1.1% in girls and 0.4% in boys. CONCLUSIONS: Our findings emphasize the importance of sexual maturity, even for a given age, for interpreting lipid levels in children.

Is there a glycemic threshold for mortality risk?

OBJECTIVE: To determine whether there are thresholds for fasting and for 2-h glucose above which the risk of death from all causes and from coronary heart disease (CHD) increases. RESEARCH DESIGN AND METHODS: We studied 23-year mortality data from the Paris Prospective Study of the 7,018 men, aged 44-55 years, who were not known as diabetic at the baseline examination. The effect of glucose concentrations on mortality was studied using the observed relative risks and an age-adjusted Cox proportional hazards model. RESULTS: For all causes of death, there were J-shaped relationships with both fasting and 2-h glucose concentrations, and the lowest observed death rates were in the intervals centered on 5.5 mmol/l for fasting glucose and 5.0 mmol/l for 2-h glucose. The death rates for CHD were low in this population: for fasting glucose, the hazards ratio was best modeled by a positive linear relationship; for 2-h glucose, it was modeled by a J-shaped curve and the lowest observed death rate was in the interval centered on 6.0 mmol/l. CONCLUSIONS: In the Paris Prospective Study, there were no clear thresholds for fasting or 2-h glucose concentrations above which mortality sharply increased; in the upper levels of the glucose distributions, the risk of death progressively increased with increasing fasting and 2-h glucose concentrations.

[Pharmacoepidemiology of diabetes: contribution of a survey of health insurance cases].

To determine the pattern of treatment of diabetes and its complications, data from a specific study performed by the French healthcare system were used. Between the 10th and 15th of May 1993, all the prescriptions for which a reimbursement was asked were registered with the age and sex of the subject for whom the prescription was written. Patients with a prescription of antidiabetic (AD) drugs were classified as diabetic. Among the 125,883 prescriptions at least one antidiabetic drug is present on 3339 (2.7%). The mean number of AD drugs prescribed is 1.3 and varies from 1 to 4. Eighty five per cent of the patients are treated with oral anti diabetic drugs alone (OAD) and 15% with insulin, alone (89%) or in association with OAD (11%). The total number of drugs (antidiabetic drugs included) prescribed for one patient varied from 1 to 18 (mean: 5.7) and is higher in women than in men. Drugs which are indicated in cardiovascular diseases (lipids lowering, blood pressure lowering drugs) are more frequent on "diabetic" prescriptions than on non diabetic ones. Most (66%) of the prescriptions are written on special forms (100% reimbursement). These forms are more often used for insulin treated patients (87%) than for non insulin treated patients (62%). Most (91%) of the prescriptions are written by a general practitioner. Taking into account the antidiabetic drugs specificity and the data base used, these results can be extrapolated to the all french diabetic population.

[Epidemiology, management and costs of type 2 diabetes in France in 1998].

Almost 10 years after the Saint Vincent declaration, a large effort was undertaken in France to improve medical care of type 2 diabetes and to limit the dreadful complications of this pathology. As expert recommendations grow in number, it appears necessary to update knowledge on the epidemiological, medical care, and cost aspects of this illness in France. In this aim, a systematic review of the medical and economic literature on type 2 diabetes was performed. Prevalence of type 2 diabetes probably reaches 2.2% in the general population, which represents 1.3 million people in France. Among these people, almost 60% are overweighted, 50% suffer high blood pressure and 30% have a treated dyslipaemia. Coronary pathologies concern 20% to 30% of type 2 diabetes patients, neuropathies 10% to 30% and ocular problems 10% to 35%. Medical care consumption of type 2 diabetes patients probably represents almost 20,000 FF per patient and per year, i.e., twice the average medical care consumption in the French population. Yet, these estimates should be considered with caution since a lot of uncertainty remains on the epidemiological, medical care, and cost aspects of type 2 diabetes in France. As diabetes has become a national public health priority, it is important to initiate new studies to have precise indicators in these different fields.
