Abstract

The objective of the present study was to analyse the association between cigarette smoking and progression of retinopathy and nephropathy, respectively, in a prospective multicentre study including 636 people with Type 1 diabetes: 81% of the original cohort of consecutively referred patients, aged 15 to 40 years and free of severe late diabetic complications. At baseline, all patients had participated in a 5-day in-patient group treatment and teaching programme for intensification of insulin therapy. Patients were examined at recruitment, and after 1, 2, 3 and 6 years including assessment of smoking status, blood pressure, metabolic control, and degree of nephropathy. Degree of retinopathy was assessed by ophthalmoscopy or fundus photography at baseline and after 6 years. Several logistic regression analyses were performed by describing the responses retinopathy and nephropathy, respectively, either as progression yes/no or as actual status at the 6-year follow-up and by using different measures for smoking. Adjustments for important covariables were made. While significant associations between smoking, and retinopathy and nephropathy respectively, were found, the relations were variable depending on the statistical model used. The results show that the real associations between smoking and retinopathy and nephropathy are complex and that more emphasis should be put on the complete description of the response variables and the statistical models used in clinical and epidemiological research.

Abstract

Objective: To document that strict dietary regimen are not necessary in the context of intensified insulin therapy., Design: German multicentre, prospective cohort study; 6 years follow-up., Setting: Ambulatory examination using a mobile ambulance., Subjects: A total of 636 type 1 diabetic patients (age 33 +/- 7 years, diabetes duration 15 +/- 7 years; mean +/- SD), who had participated in a structured, 5-day, in-patient, group treatment and teaching programme for intensification of insulin therapy and liberalization of the diabetes diet 6 years prior to follow-up., Main Outcome Measures: Relations between the extent to which patients practise a liberalized diet, the degree of metabolic control (HbA1c, severe hypoglycaemia, body mass index, cholesterol), and the patients' perceived burden through dietary treatment., Results: In the total patient group, HbA1c was 7.9 +/- 1.6%, and the incidence of severe hypoglycaemia was 0.17 cases per patient during the preceding year; 31% patients injected insulin < or = 3 times per day, 58% 4-7 times per day, and 11% used insulin pump therapy. Only 11% patients reported following a meal plan, whereas 89% continually changed timing and amount of carbohydrate intake; only 5% had the same number of meals every day, whereas as many as 20% varied the number of meals per day by four or more; 53% skipped main meals; 85% habitually consumed sugar or sugar containing foods. Patients with a higher degree of diet liberalization injected insulin or used an insulin pump therapy more frequently, and perceived their dietary treatment to be less burdensome. No clinically significant associations were found between the extent of diet liberalization and metabolic control., Conclusions: Under the conditions where type 1 diabetic patients have the opportunity to participate in an intensified insulin treatment and teaching programme, liberalization of the diabetes diet is not associated with adverse effects on glycaemic control, but is associated with less perceived burden through dietary treatment.

Abstract

Objectives: Repeatability of a dietary method is important in determining the quality of nutritional data. It should be assessed in the population of interest. This study evaluated the repeatability of nutritional data from standardized three-day dietary records, from the clinic-based, cross-sectional multi-centre EURODIAB IDDM Complications Study. Design and Subjects: 15% of the total EURODIAB cohort was randomly selected to test the repeatability of nutritional intake data. Two three-day records, completed three weeks apart, were available for 216 diabetic patients (7.5%) representative of the total cohort. All records were analysed centrally, for intakes of protein (animal and vegetable), fat (saturated fat and cholesterol), carbohydrate, fibre, alcohol and energy. Repeatability was measured comparing mean intakes, determining the proportion of patients classified into the same/opposite quartile by the two three-day records and assessing mean differences with standard deviations (s.d.d). Results: There were no significant differences in mean energy and nutrient intakes between the first and second records. Classification of individuals into the opposite quartile occurred only in 0–4% of patients and overall about 50% (range 44–74%) of the subjects were classified into the same quartiles of intakes. Only small mean differences were found for energy intake (−156 (1633) kJ; 95% confidence limits −375, 63 kJ) and nutrients with s.d.ds comparable to intra-individual variations in the general population. The differences in energy intake were randomly distributed over the range of intakes. Conclusions: The present study demonstrates that standardized three day dietary records show a high degree of repeatability within a short period of time in a sample of European IDDM patients. The good repeatability strengthens the conclusions drawn from the nutritional data in the EURODIAB IDDM Complications Study. Sponsorship: Nutrition Co-ordinating Centre research funds, Diabetes Research Institute at Heinrich-Heine University, Dusseldorf. The EURODIAB IDDM Complications Study was supported by the European Community.

Abstract

Several studies have shown an association between blood pressure and nephropathy, but few have been large enough to examine whether, or how, this relation is influenced by retinopathy. We have therefore examined the independent relations of blood pressure to urinary albumin excretion and retinopathy in a cross-sectional observational study of over 3000 insulin-dependent diabetic patients (the EURODIAB IDDM Complications Study). The relation of blood pressure to urinary albumin excretion differed strikingly between patients with (46%) and without (54%) retinopathy. In those with retinopathy, mean urinary albumin excretion rate was normal (20 micrograms/min) below median diastolic pressure (75 mmHg) and increased steeply (p0.001) with blood pressure above this level. However, in patients without retinopathy, mean albumin excretion rate was normal across the range of diastolic pressure. This finding could not be explained by differences in glycaemic control or duration of diabetes between patients with and without retinopathy. These data identify a subgroup of patients whose high risk of nephropathy may reflect abnormal renal vulnerability to mildly raised blood pressure. Retinopathy is a close correlate of this vulnerability. Detection of even mild retinopathy, together with raised blood pressure, may be important in assessing nephropathy risk.

Abstract

OBJECTIVE To examine the relationship between smoking and both glycemic control and microvascular complications in patients with insulin-dependent diabetes mellitus (IDDM). RESEARCH DESIGN AND METHODS This was a prevalence survey of 3,250 men and women aged 15–60 years with IDDM from 31 diabetes centers in 16 European countries. Participants completed a questionnaire, had retinal photographs taken, and performed a 24-h urine collection. HbA1c, frequency of hypoglycemic and ketoacidotic episodes, urinary albumin excretion rates, and retinopathy were compared by smoking category. RESULTS The prevalence of smoking was 35% in men and 29% in women. Current smokers had poorer glycemic control and, among men, were more likely to have had a ketoacidotic episode than were those who never smoked. Ex-smokers had equivalent glycemic control and marginally more hypoglycemic episodes did than those who never smoked. Current smokers had a higher prevalence of microalbuminuria and total retinopathy than did those who never smoked. Ex-smokers had a higher prevalence of macroalbuminuria and proliferative retinopathy than did those who never smoked, but both had a similar prevalence of microalbuminuria. Adjustment for either current or long-term glycemic control could not fully account for these differences. CONCLUSIONS Smoking is associated with poorer glycemic control and an increased prevalence of microvascular complications compared with not smoking. Ex-smokers can achieve glycemic control equivalent to and have a prevalence of early complications similar to that of those who never smoked. We suggest that poorer glycemic control can account for some of the increased risk of complications in smokers, and that quitting smoking would be effective in reducing the incidence of complications. Urgent action is required to reduce the high smoking rates in people with IDDM.
