Abstract Aim To examine the effects of group visits and computer-assisted consultations on quality of life and glycaemic control in adolescents with Type 1 diabetes. Methods A total of 116 adolescents, aged 11,17 years, and their parents were randomly assigned to an intervention (n = 62) or a control group (n = 54). The intervention group was invited to a 15-month programme comprising group visits and computer-assisted consultations. The control group was offered traditional out-patient consultations. Outcomes included changes in HbA1c and the adolescents' assessment of generic and disease-specific health-related quality of life measured by the Child Health Questionnaire (CHQ-CF87) and the Diabetes Quality of Life Questionnaire (DQOL), respectively. Results One hundred and one adolescents (55/46) agreed to participate, mean age 14.2 years (sd 1.5), mean diabetes duration 6.5 years (sd 3.6, range 1,16 years), mean HbA1c 9.3% (sd 1.4, range 6.1,12.8%). Eighty-three (72%) completed the questionnaires at follow-up (intervention/control 45/38). There were significant age by randomization group interactions for diabetes-related impact (P = 0.018), diabetes-related worries (P = 0.004), mental health (P = 0.046) and general behaviour (P = 0.029), implying that the intervention was effective in older adolescents (above 13,14 years). No significant effects on mean HbA1c were identified. Conclusions Group visits and computer-assisted consultations had beneficial effects on health-related quality of life in older adolescents, the role of this intervention being questionable in younger adolescents.

Biphasic insulin aspart 70/30 vs. insulin glargine in insulin naïve type 2 diabetes patients: modelling the long-term health economic implications in a Swedish setting

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 6 2008
G. Goodall
Summary Objectives:, To evaluate the long-term clinical and economic outcomes of biphasic insulin aspart 70/30 (BIAsp 70/30) treatment vs. insulin glargine in insulin naïve, type 2 diabetes patients failing oral antidiabetic drugs in a Swedish setting. Methods:, A published and validated computer simulation model (the CORE Diabetes Model) was used to project life expectancy, quality-adjusted life expectancy (QALE) and costs over patient lifetimes. Cohort characteristics [54.5% male, mean age 52.4 years, 9 years mean diabetes duration, mean glycosylated haemoglobin (HbA1c) 9.77%] and treatment effects were based on results from the Initiate Insulin by Aggressive Titration and Education (INITIATE) clinical trial. Direct medical costs were accounted in 2006 Swedish Kronor (SEK) and economic and clinical benefits were discounted at 3% per annum. Results:, Biphasic insulin aspart 70/30 treatment when compared with insulin glargine treatment was associated with improvements in discounted life expectancy of 0.21 years (13.10 vs. 12.89 years) and QALE of 0.21 quality-adjusted life years (QALYs) (9.16 vs. 8.96 QALYs). Reductions in the incidence of diabetes-related complications in the BIAsp 70/30 treatment arm led to reduced total costs of SEK 10,367 when compared with insulin glargine (SEK 396,475 vs. SEK 406,842) over patient lifetimes. BIAsp 70/30 treatment was projected to be dominant (cost and lifesaving) when compared with insulin glargine in the base case analysis. Conclusions:, Biphasic insulin aspart 70/30 treatment was associated with improved clinical outcomes and reduced costs compared with insulin glargine treatment over patient lifetimes. These results were driven by improved HbA1c levels associated with BIAsp 70/30 compared with insulin glargine and the accompanying reduction in diabetes-related complications despite increases in body mass index.

Abstract Background:, Many factors contribute to the need for prandial insulin in Type 1 diabetes. However, patients' success in achieving normal postprandial glucose concentration is understudied. The aim of the present study was to determine how often patients with Type 1 diabetes achieve normal postprandial glucose concentrations and to evaluate factors associated with postprandial hypo- and hyperglycemia. Methods:, Data on food intake, physical activity, insulin administration, and blood glucose concentration were collected using a self-administered questionnaire from 331 patients with Type 1 diabetes (43% men; mean age 49 ± 12 years; mean diabetes duration 32 ± 13 years). Of these, 179 provided data on blood glucose concentrations measured 110,150 min postprandially. One such meal per patient was randomized for analyses. Results:, Hypoglycemia (<4.0 mmol/L), normoglycemia (4.0,7.9 mmol/L), and hyperglycemia (,8.0 mmol/L) were observed after 23%, 36%, and 41% of meals, respectively. The three postprandial glycemia groups did not differ with respect to the meal composition or the timing of the postprandial blood glucose measurement. In women, postprandial hyperglycemia was associated with shorter diabetes duration and higher preprandial blood glucose concentration, whereas postprandial hypoglycemia was associated with higher physical activity. No single factor explained the postprandial glycemic state in men. Conclusions:, A total of 64% of patients estimated their prandial insulin need inappropriately, suggesting that estimation of the optimal prandial insulin dose is not easy, even after a long duration of diabetes.

Aim:, To estimate the risk of diabetic nephropathy and associated risk factors in a nationwide cohort of childhood-onset type 1 diabetes mellitus (T1DM) and 19,30 yr of diabetes duration. Methods:, Patients diagnosed with childhood-onset T1DM (<15 yr) from 1973 through 1982, who previously (1989,1990) participated in a clinical examination to assess diabetic complications, were invited for a new examination in 2002,2003. Of 355 eligible patients, 299 participated (84.2%), and complete urine samples for evaluation of albuminuria were obtained from 295 patients, with a mean age of 33 yr (range 20.9,44.0) and mean diabetes duration of 24 yr (range 19.3,29.9). Persistent microalbuminuria and overt nephropathy [albumin excretion rate (AER) 15,200 ,g/min and AER > 200 ,g/min, respectively] in at least two out of three consecutive overnight urine samples were defined as diabetic nephropathy. Results:, Overt nephropathy was found in 7.8% [95% confidence interval (CI) 4.7,10.9] and persistent microalbuminuria in 14.9% (95% CI 10.8,19.0) of the subjects. Hemoglobin A1c (HbA1c) (p = 0.001), systolic blood pressure (BP) (p = 0.002), total cholesterol (p = 0.019), and C-reactive protein (CRP) (p = 0.019) were associated with diabetic nephropathy. Significant predictors in 1989,1990 for the development of diabetic nephropathy in 2002,2003 were HbA1c (p < 0.001), AER (p = 0.007), and cholesterol (p = 0.022). Conclusions:, In a subgroup of patients diagnosed with childhood-onset T1DM in 1973,1982, 7.8% had overt nephropathy after 19,30 yr of diabetes duration, which is low compared with studies from other countries. HbA1c, systolic BP, total cholesterol, and CRP were each independently associated with diabetic nephropathy. [source]

Abtract: Background: The Diabetes Control and Complications Trial (DCCT) demonstrated that the rate-limiting step to the intensification of diabetes management in adolescents and adults was hypoglycemia. Young children were presumed to be at even greater risk for hypoglycemia with severe consequences, particularly if they had HbA1c levels < 8%. Subjects: A retrospective chart review was performed on 148 patients with type 1 diabetes on insulin injection therapy who were < 8 yr of age (mean age 5.7 ± 1.5, mean diabetes duration 3.0 ± 1.4 yr) followed quarterly from July 1999 to June 2001. Methods:, The subjects were divided into two groups based on their mean HbA1c values (< 8 vs. , 8%) averaged over the 2-yr time period. The following variables were analyzed comparing the two groups: age, duration of diabetes, insulin dose, severe hypoglycemic episodes, episodes of diabetic ketoacidosis (DKA), percentage of glucose levels above, within, and below the target range, and number of diabetes home-management competencies obtained. Results:, Patients with HbA1c < 8% spent more time within target range (40.0 vs. 29.5%, p = 0.0001) and less time above their target range (36.9 vs. 51.2%, p = 0.0003). There was no difference in the percentage of glucose levels below target (23.2 vs. 19.4%, p = NS), percentage of severe hypoglycemic episodes (3 vs. 7 episodes per 100 patient-yr, p = NS), or episodes of DKA (1 vs. 3 episodes per 100 patient-yr, p = NS) between the two groups. Subjects with lower HbA1c levels had acquired more home-management competencies (4.0 vs. 3.5, p = 0.01). Conclusions:, If families are competent in fundamental diabetes management, young children can achieve HbA1c levels < 8.0% without increasing the risk of hypoglycemia. [source]
