- AIMS: Patients with Type 2 diabetes and coronary heart disease (CHD) are infrequently treated to risk factor targets in current guidelines. We aimed to examine risk factor management and control levels in a large sample of patients with Type 2 diabetes with CHD. METHODS: This was an observational study of 1612 patients with first incidence of CHD before 2002, and of 4570 patients with first incidence of CHD before 2005, from the Swedish National Diabetes Register (NDR). RESULTS: In patients with CHD 1-2 years before follow-up, the achievement of cardiovascular risk factor targets (follow-up 2002/follow-up 2005) was: HbA(1c) < 7%, 47%/54% (P < 0.01); blood pressure < or = 130/80 mmHg, 31%/40% (P < 0.001); total cholesterol < 4.5 mmol/l, 47%/60% (P < 0.001); and low-density lipoprotein-cholesterol < 2.5 mmol/l, 49%/65% (P < 0.001). Use of medication: antihypertensives, 90%/94% (P < 0.01); lipid-lowering drugs, 75%/86% (P < 0.001); and aspirin, 85%/89% (P < 0.05). A high prevalence of adverse lifestyle characteristics prevailed (2002/2005): overweight [body mass index (BMI) > or = 25 kg/m(2)], 86%/85%; obesity (BMI > or = 30 kg/m(2)), 41%/42%; smokers in age group < 65 years, 16-23%/18-19%; as well as waist circumference > or = 102 cm (men) or > or = 88 cm (women), 68% in 2005. CONCLUSIONS: Patients with a combination of Type 2 diabetes and CHD showed an increased use of lipid-lowering drugs over time, corresponding to improving blood lipid levels. A discrepancy existed between the prevalent use of antihypertensive drugs and the low proportion reaching blood pressure targets. Regretfully, a high prevalence of adverse lifestyle characteristics prevailed. Evidence-based therapy with professional lifestyle intervention and drugs seems urgent for improved quality of secondary prevention in these patients.

Journal article (peer-reviewed)abstract
- Aims Between 1998 and 2005, a number of definitions of the metabolic syndrome (MetS) have been proposed. The aim of this population-based cohort study was to compare prevalence rates and the prediction of cardiovascular disease (CVD) using different definitions of MetS. Methods A total of 5047 non-diabetic subjects (66% women), from the city of Malmo, Sweden, were followed. The incidence of fatal and non-fatal CVD (cardiac events, n = 176, and stroke, n = 171) was monitored over 11 years of follow-up. MetS was defined in three different ways [by International Diabetes Federation (IDF), National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATPIII), or European Group for the study of Insulin Resistance (EGIR) criteria] based on data on waist circumference, blood pressure, serum triglycerides, High-density lipoprotein cholesterol and fasting blood glucose. The IDF definition identified 21.9% of the subjects having the MetS. Corresponding figures for the NCEP-ATPIII and EGIR definitions were 20.7 and 18.8%, respectively. Results After taking age, gender, low-density lipoprotein cholesterol and lifestyle factors into account, the hazard ratio (HR) for CVD event according to the IDF, NCEP-ATPIII and EGIR definitions were HR 1.11 (95% CI: 0.86-1.44), 1.59 (1.25-2.03) and 1.35 (1.05-1.74), respectively. The results were largely similar for cardiac and stroke events. Conclusions The prevalence of Mets according to the IDF definition was higher in comparison with NCEP-ATPIII and EGIR definitions, but the IDF definition was not superior to these definitions for prediction of CVD events. This was true for both genders and questions the usefulness of the current IDF criteria of MetS in a North-European, Caucasian population. In addition, single risk factors such as smoking had an equal prediction as the metabolic syndrome.

Sorbitol and myo-inositol levels and morphology of sural nerve in relation to peripheral nerve function and clinical neuropathy in men with diabetic, impaired, and normal glucose tolerance
- 2000
-
In: Diabetic Medicine. - : Wiley. - 0742-3071 .- 1464-5491. ; 17:4, s. 259-268
-
Journal article (peer-reviewed)abstract
- Aims: Sorbitol and myo-inositol levels and morphology of sural nerve were compared with nerve function and clinical neuropathy in men with diabetic, impaired (IGT), and normal glucose tolerance. Methods: After neurography of sural nerve and determinations of sensory thresholds for vibration, warm and cold on the foot, whole nerve sural nerve biopsy was performed in 10 men with Type 1 diabetes mellitus, 10 with IGT, and 10 with normal glucose tolerance. Polyol levels were assessed by gas-liquid chromatography/mass spectrometry. Results: Sural nerve amplitudes were significantly lower and sorbitol levels significantly higher in diabetic patients (median (interquartile range)) (3.7 (3.5) μV and 643 (412) pmol/mg protein, respectively) both compared with IGT (11.3 (10.6) μV; P = 0.04 and 286 (83) pmol/mg protein; P = 0.0032, respectively) and normally glucose tolerant (10.0 (11.6); P = 0.0142 and 296 (250) pmol/mg protein; P = 0.0191, respectively) subjects. There were no differences in nerve morphology between the three groups. Nerve myo-inositol levels correlated, however, positively with cluster density (r(s) = 0.56; P = 0.0054). In diabetic and IGT subjects, sural nerve amplitudes (2.6 (3.8) vs. 12.1 (10.6) μV; P = 0.0246) and myelinated nerve fibre density (MNFD; 4076 (1091) vs. 5219 (668) nerve fibres/mm2; P = 0.0021) were significantly lower in nine subjects with clinical neuropathy than in 10 without. Conclusions: Nerve degeneration (i.e. MNFD) correlated with clinical neuropathy but not with glucose tolerance status whereas nerve myo-inositol levels positively correlated with signs of nerve regeneration (i.e. increased cluster density).

Telomere length in blood and skeletal muscle in relation to measures of glycaemia and insulinaemia.
- 2012
-
In: Diabetic Medicine: A journal of the British Diabetic Association. - : Wiley. - 1464-5491 .- 0742-3071. ; 29:10, s. 377-381
-
Journal article (peer-reviewed)abstract
- Aims: Skeletal muscle is a major metabolic organ and plays important roles in glucose metabolism, insulin sensitivity and insulin action. Muscle telomere length reflects the myocyte's exposure to harmful environmental factors. Leukocyte telomere length is considered a marker of muscle telomere length and is used in epidemiologic studies to assess associations with ageing-related diseases where muscle physiology is important. However, the extent to which leucocyte and muscle telomere length are correlated is unknown, as are their relative correlations with glucose and insulin concentrations. The purpose of this study was to determine the extent of these relationships. Methods: Leucocyte and muscle telomere length were measured by quantitative real-time polymerase chain reaction in participants from the Malmö Exercise Intervention (n = 27) and the Prevalence, Prediction and Prevention of Diabetes-Botnia studies (n = 31). Participants in both studies were free from Type 2 diabetes. We assessed the association between leucocyte telomere length, muscle telomere length and metabolic traits using Spearmen correlations and multivariate linear regression. Bland-Altman analysis was used to assess agreement between leucocyte and muscle telomere length. Results: In age-, study-, diabetes family history- and sex-adjusted models, leucocyte and muscle telomere length were positively correlated (r = 0.39, 95% CI 0.15-0.59). Leucocyte telomere length was inversely associated with 2-h glucose concentrations (r = -0.58, 95% CI -1.0 to -0.16), but there was no correlation between muscle telomere length and 2-h glucose concentrations (r = 0.05, 95% CI -0.35 to 0.46) or between leucocyte or muscle telomere length with other metabolic traits. Conclusions: In summary, the current study supports the use of leucocyte telomere length as a proxy for muscle telomere length in epidemiological studies of Type 2 diabetes aetiology.

- Aims Subcutaneous injection of recombinant human GAD65 (rhGAD65) in patients with latent autoimmune diabetes in adults (LADA) correlates with an increase in C-peptide levels. In this study we analysed the effect of rhGAD65 administration on the GAD65-specific autoimmune response. Methods Longitudinal serum samples obtained from LADA patients (n = 47) who received 4, 20, 100 or 500 mu g alum-formulated rhGAD65 or placebo by subcutaneous injection twice (4 weeks apart) were analysed for their epitope recognition using GAD65-specific recombinant Fab and GAD65/67 fusion proteins. Results Overall, minor changes in the epitope pattern were observed using either approach. Only in the 500-mu g dosage group was an increase in GAD65Ab level associated with a significant increase in the binding to a conformational epitope located at the middle part of GAD65. Conclusions Our data suggest that the apparent beneficial effects of 20 mu g alum-formulated recombinant human GAD65 is not explained by changes in the GAD65Ab epitope pattern.

Diabetes, healthcare cost and loss of productivity in Sweden 1987 and 2005-a register-based approach
- 2009
-
In: Diabetic Medicine. - : Wiley. - 1464-5491 .- 0742-3071. ; 26:9, s. 928-934

Journal article (peer-reviewed)abstract
- Aim The aim of this study was to estimate healthcare cost and productivity losses as a result of diabetes and diabetes-related chronic complications in Sweden in 1987 and 2005. Research design and methods Published estimates on relative risks and Swedish age-specific diabetes-prevalence rates were used to calculate the proportions of diabetes-related chronic complications that are attributable to diabetes. These attributable risks were applied to cost estimates for diabetes-related chronic complications based on data from Swedish population registers. Results The estimated total costs for Sweden in 1987 and 2005 were EUR439m and EUR920m, respectively. The increase of 110% was as a result of a 69% increase in the estimated prevalence from 150 000 (1.8% of the population) to 254 000 (2.8%) and of an increase in the estimated annual cost per person diagnosed with diabetes by 24%. Healthcare accounted for 45% of the estimated cost in 1987 and for 37% in 2005. The estimated diabetes-related healthcare cost accounted for approximately 1.0% of total healthcare cost in Sweden in 1987 and for 1.4% in 2005. Diabetes per se accounted for 57% of the healthcare cost in 1987 and for 50% in 2005. The most important chronic complication was cardiovascular disease. Conclusions The cost of diabetes is substantial and increasing even in a fairly low-prevalence country such as Sweden. Measures to curb the increase in prevalence and to improve individual control of his or her diabetes seem to be the most important challenges.

Journal article (peer-reviewed)abstract
- Aims Gastroparesis is a common gastrointestinal complication in diabetes mellitus, whereas dysfunction in the other gastrointestinal organs has been less thoroughly investigated. Furthermore, it is not known whether there is any relationship between motility and dysmotility between these organs. The aim of this study was to examine whether diabetic patients with gastrointestinal symptoms also have motility disturbances in the oesophagus and stomach and, if so, whether there are any associations between these disturbances. Methods Thirty-one patients with diabetes mellitus who complained of gastrointestinal symptoms were asked to complete a questionnaire about their symptoms. They were further investigated with oesophageal manometry and gastric emptying scintigraphy. Results Fifty-eight per cent of the patients had abnormal oesophageal function, and 68% had delayed gastric emptying. Abdominal fullness was the only symptom that related to any dysfunction, and it was associated with delayed gastric emptying (P = 0.02). We did not find any relationship in motility or dysmotility between the oesophagus and the stomach. Conclusion Oesophageal dysmotility, as well as gastroparesis, are common in patients with diabetes who have gastrointestinal symptoms. It is important to investigate these patients further, to be able to reach an accurate diagnosis and instigate appropriate treatment. Our findings indicate that the oesophagus and the stomach function as separate organs and that pathology in one does not necessarily mean pathology in the other.

Low serum concentration of sulfatide and presence of sulfated lactosylceramid are associated with Type 2 diabetes. The Skaraborg Project
- 2005
-
In: Diabetic Medicine. - : Wiley. - 0742-3071 .- 1464-5491. ; 22:9, s. 1190-8

Journal article (peer-reviewed)abstract
- AIMS: The glycosphingolipid sulfatide (sulfated galactosyl-ceramide) increases exocytosis of beta-cell secretory granules, activates K(ATP)-channels and is thereby able to influence insulin secretion through its presence in the islets. A closely related compound, sulfated lactosylceramide (sulf-lac-cer), is present in the islets during fetal and neonatal life when, as in Type 2 diabetes, insulin is secreted autonomically without the usual first phase response to glucose. The aim was to examine whether serum concentrations of these glycolipids are associated with Type 2 diabetes. METHODS: A case-control study, comprising 286 women and 283 men, was designed using a population-based sample of patients with Type 2 diabetes and a population survey. RESULTS: Low serum concentrations of sulfatide were associated with Type 2 diabetes, independent of traditional risk factors for diabetes in a sex-specific analysis: odds ratio (OR) 2.1 (95% confidence interval 1.1, 3.9) in men, and 2.3 (1.2, 4.3) in women, comparing the lowest and the highest tertiles. Type 2 diabetes was also associated with detectable amounts of sulf-lac-cer in serum: OR 1.7 (0.9, 3.4) in men, and 7.6 (3.8, 15.2) in women. After adjustment for confounding from other diabetes risk factors, these associations remained basically unchanged. The connections between sulfatide and Type 2 diabetes, and sulf-lac-cer and Type 2 diabetes were independent of each other. Insulin resistance (HOMA-IR) was negatively correlated with sulfatide concentration and positively correlated with sulf-lac-cer (both P < 0.0001, independently). CONCLUSIONS: We report a new, robust and highly significant independent association between Type 2 diabetes and serum concentrations of sulfatide in both sexes, and sulf-lac-cer in females. The associations were also independent of other known diabetes risk factors.
