- Aims: To describe factors associated with prevalence or absence of microvascular and macrovascular complications in people with Type 1 diabetes of very long duration and to investigate the risk factors associated with the incidence of such complications. Methods: We included individuals with Type 1 diabetes who had been entered in the Swedish National Diabetes Register between 2002 and 2004 (n = 18 450). First, risk factor distribution in people with diabetes duration of ≥ 50 years was compared between people with and without complications. Second, the incidence of complications during a 10-year follow-up period was studied in all individuals who had no complications at baseline. Results: Among people with a diabetes duration of ≥ 50 years (n = 1023), 453 (44%) had macrovascular disease, 534 (52%) had microvascular disease and 319 (31%) did not have either of the diagnoses. Factors that differed significantly between people with and without macrovascular disease were gender, age, HbA1c, BMI, LDL cholesterol, HDL cholesterol, triglycerides, systolic blood pressure, albuminuria, antihypertensive medication and lipid-lowering medication. The same factors differed significantly between people with and without microvascular disease, with the exception of gender and HDL cholesterol. During the follow-up period, 6.1% of the study cohort were diagnosed with macrovascular disease and 19.6% with microvascular disease. Incidence of macrovascular disease was significantly associated with HbA1c levels. Hazard ratios decreased with longer diabetes duration. Conclusions: People with Type 1 diabetes who have survived ≥ 50 years without complications are significantly younger, and have significantly lower HbA1c levels, BMI and triglyceride levels than survivors with complications. HbA1c level is a predictor of macrovascular disease, independently of diabetes duration.

Tidskriftsartikel (refereegranskat)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 The aim of this study was to examine the fear of hypoglycaemia and its association with demographic and disease-specific variables in a large and unselective population of adult patients with Type 1 diabetes. Methods Questionnaires were sent by post to all patients with Type 1 diabetes who were identified in the local diabetes registries of two hospitals in Stockholm, Sweden (n = 1387). Fear of hypoglycaemia was measured using the Swedish Hypoglycaemia Fear Survey, the Worry subscale and the Aloneness subscale. Demographic variables and disease-specific factors were collected from patients' self reports and medical records. Univariate analysis and multiple stepwise linear regression analysis were used in the statistical analyses of the data. Results Seven hundred and sixty-four (55%) patients participated in the study (mean age 43.3 years and mean HbA(1c) 7.0%, normal < 5.0%). The Hypoglycaemia Fear Survey - Worry subscale was significantly associated with frequency of severe hypoglycaemia, number of symptoms during mild hypoglycaemia, gender, hypoglycaemic symptoms during hyperglycaemia and hypoglycaemic unawareness. The Hypoglycaemia Fear Survey - Aloneness subscale was significantly associated with frequency of severe hypoglycaemia, number of symptoms during mild hypoglycaemia, gender, frequency of mild hypoglycaemia, HbA(1c) , hypoglycaemic unawareness and visits to the emergency room because of severe hypoglycaemia. Fear of hypoglycaemia proved to be more prevalent in females and indicated a different pattern between genders in relation to factors associated with fear of hypoglycaemia. Conclusions This study identifies the frequency of severe hypoglycaemia as the most important factor associated with fear of hypoglycaemia. Moreover, for the first time, we document gender differences in fear of hypoglycaemia, suggesting that females are more affected by fear of hypoglycaemia than men.

Tidskriftsartikel (refereegranskat)abstract
- AIM: The relative roles(s) of impaired insulin secretion vs. insulin resistance in the development of gestational diabetes mellitus depend upon multiple risk factors and diagnostic criteria. Here, we explored their relative contribution to gestational diabetes as defined by the WHO 1999 (GDM1999) and adapted WHO 2013 (GDM2013) criteria, excluding the 1-h glucose value, in a high-risk Indian population from Punjab.METHODS: Insulin secretion (HOMA2-B) and insulin action (HOMA2-IR) were assessed in 4665 Indian women with or without gestational diabetes defined by the GDM1999 or adapted GDM2013 criteria.RESULTS: Gestational diabetes defined using both criteria was associated with decreased insulin secretion compared with pregnant women with normal glucose tolerance. Women with gestational diabetes defined by the adapted GDM2013, but not GDM1999 criteria, were more insulin resistant than pregnant women with normal glucose tolerance, and furthermore displayed lower insulin secretion than GDM1999 women. Urban habitat, illiteracy, high age and low BMI were independently associated with reduced insulin secretion, whereas Sikh religion, increasing age and BMI, as well as a family history of diabetes were independently associated with increased insulin resistance.CONCLUSIONS: Gestational diabetes risk factors influence insulin secretion and action in North Indian women in a differential manner. Gestational diabetes classified using the adapted GDM2013 compared with GDM1999 criteria is associated with more severe impairments of insulin secretion and action.

- Aim The balance between T helper cell subsets is an important regulator of the immune system and is often examined after immune therapies. We aimed to study the immunomodulatory effect of glutamic acid decarboxylase (GAD) 65 formulated with aluminium hydroxide (GAD-alum) in children with Type 1 diabetes, focusing on chemokines and their receptors. Methods Blood samples were collected from 70 children with Type 1 diabetes included in a phase II clinical trial with GAD-alum. Expression of CC chemokine receptor 5 (CCR5) and CCR4 was analysed on CD4+ and CD8+ lymphocytes after in vitro stimulation with GAD(65) using flow cytometry, and secretion of the chemokines CCL2, CCL3 and CCL4 was detected in peripheral blood mononuclear cell supernatants with Luminex. Results Expression of Th1-associated CCR5 was down-regulated following antigen challenge, together with an increased CCR4/CCR5 ratio and CCL2 secretion in GAD-alum-treated patients, but not in the placebo group. Conclusion Our results suggest that GAD-alum treatment has induced a favourable immune modulation associated with decreased Th1/Tc1 phenotypes upon antigen re-challenge, which may be of importance for regulating GAD(65) immunity. © 2012 The Authors.

- Community-wide fundus photography was organized for early detection of diabetic retinopathy (DR) by mobile teams. High-quality three-field Kodachrome fundus photography, performed according to the London Protocol through dilated pupils was offered free of charge to primary care; images were taken in the community and assessed centrally. Data are presented from the first 80 primary health care centres (PHCCs) participating, serving 990 000 (about 60 %) of inhabitants in Stockholm County. Beginning in 1990, 6863 diabetes patients were invited by PHCCs; 5490 (80 %) attended. We reached 77 % of persons with known diabetes; only 37 % had had their eyes examined during the preceding 2 years. For 97 % of patients, images were assessable. DR was present in 34 % of patients (non-proliferative DR not requiring further assessment 29 %, non-proliferative DR requiring further assessment 1.1 %, proliferative DR 0.5 % and macular involvement 3.6 %). Re-examination after 2 years was offered to 64 %; follow-up photography after 1 year to 24 %. Fluorescein angiography and/or photocoagulation treatment was performed in 3.6 %. This method of early diagnosis is feasible, acceptable, and reached twice as many patients as did the usual referral-based system of care. We now plan to extend this service to cover the whole county.

- 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.

- 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.

- 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.

Forskningsöversikt (refereegranskat)abstract
- AIMS: To review the difference in carotid artery intima media thickness (IMT) between patients with Type 2 diabetes (DM) or impaired glucose tolerance (IGT), and control subjects. METHODS: Systematic reviews were made in order to identify cross-sectional studies using the ultrasound method. The differences between IMT in DM or IGT and control subjects were calculated. Meta-analysis using random-effects modelling was used to calculate summary measures. RESULTS: Twenty-three studies included 24,111 subjects; 4019 with DM and 1110 with IGT. In 20 of 21 studies, the diabetic patients had greater carotid artery IMT than the subjects in the control groups. The estimated mean difference in IMT was 0.13 (95% CI: 0.12-0.14) mm. Heterogeneity was observed and likely sources of variation were study size, diabetes duration, and ultrasound method. In three out of nine studies, the IGT patients had significant greater carotid artery IMT than the subjects in the control groups. The estimated mean difference in IMT was 0.04 (95% CI: 0.014-0.071) mm. CONCLUSIONS: Type 2 diabetes was associated with an 0.13 mm increase in IMT compared with control subjects. In patients with IGT, the increase in IMT was about one-third of that observed in diabetes. The observed difference in IMT can be interpreted as if the diabetes patients were more than 10 years older than the control groups, and that the relative risks of myocardial infarction and stroke were increased by almost 40%, respectively.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- To monitor changes over time in the incidence of blindness among people with diabetes, referrals (mentioning diabetes) to all vision rehabilitation centres in Stockholm County (1995 population 1 725 756) during 1981-1995 were registered. A mass mailing to people with diabetes in 1989 urged them to have their eyes examined. Mobile fundus photography teams initiated early diagnosis of diabetic retinopathy in primary health care in 1990. Referrals with diabetes and blindness, defined (WHO, ICD 10) as best-corrected visual acuity (VA) of the better eye less than 3/60 (0.05), occurred for 172 persons (7.6% of those referred with diabetes). During 1981-1985, 93 were referred (95% confidence interval 75 to 114); 1986-1990, 51 (38 to 67); 1991-1995, 28 (19 to 41). Five-year average annual incidence rate of referrals with blindness was reduced by 47% from 1.2 to 0.63 to 0.33 per 100,000 population. Mean yearly reduction during 1981-1995 was 11% (8 to 15%), 11.5% (8 to 15%) if blindness was defined as in the UK (VA 3/60 or less), and 7% (4 to 9%) for legal blindness (VA 6/60 or less); test for trend p < 0.001 (Poisson regression analysis). This is the first report of reduction in a geographical region of a proxy measure for new blindness in diabetes by one-third or more, attaining one of the main targets of the St Vincent Declaration.

- AIMS: To assess the importance of family factors in determining metabolic outcomes in adolescents with Type 1 diabetes in 19 countries.METHODS: Adolescents with Type 1 diabetes aged 11-18 years, from 21 paediatric diabetes care centres, in 19 countries, and their parents were invited to participate. Questionnaires were administered recording demographic data, details of insulin regimens, severe hypoglycaemic events and number of episodes of diabetic ketoacidosis. Adolescents completed the parental involvement scale from the Diabetes Quality of Life for Youth--Short Form (DQOLY-SF) and the Diabetes Family Responsibility Questionnaire (DFRQ). Parents completed the DFRQ and a Parental Burden of Diabetes score. Glycated haemoglobin (HbA(1c)) was analysed centrally on capillary blood.RESULTS: A total of 2062 adolescents completed a questionnaire, with 2036 providing a blood sample; 1994 parents also completed a questionnaire. Family demographic factors that were associated with metabolic outcomes included: parents living together (t = 4.1; P < 0.001), paternal employment status (F = 7.2; d.f. = 3; P < 0.001), parents perceived to be over-involved in diabetes care (r = 0.11; P < 0.001) and adolescent-parent disagreement on responsibility for diabetes care practices (F = 8.46; d.f. = 2; P < 0.001). Although these factors differed between centres, they did not account for centre differences in metabolic outcomes, but were stronger predictors of metabolic control than age, gender or insulin treatment regimen.CONCLUSIONS: Family factors, particularly dynamic and communication factors such as parental over-involvement and adolescent-parent concordance on responsibility for diabetes care appear be important determinants of metabolic outcomes in adolescents with diabetes. However, family dynamic factors do not account for the substantial differences in metabolic outcomes between centres

- Diabet. Med. 29, 10551059 (2012) Aim To examine the availability of insulin pump therapy in patients with Type 1 diabetes. Methods Patients using insulin pumps among a cohort of 7224 patients with Type 1 diabetes were studied. Results In logistic regression, used to evaluate variables not changing over time among the total cohort, use of insulin pumps varied by outpatient clinic (P < 0.001) and sex (P < 0.001). Cox regression analysis in 5854 patients with detailed patient data prior to use of an insulin pump showed higher HbA1c (P < 0.0001), lower creatinine (P = 0.002), high and low insulin doses (P < 0.0001), younger age (P < 0.0001) and female sex (P < 0.0001) to be associated with use of an insulin pump. Women were 1.5-fold more likely to start using an insulin pump (hazard ratio 1.52, 95% confidence interval 1.291.79) and patients in the 20- to 30-years age range were more than twice as likely to begin use of an insulin pump than patients aged 4050 years (hazard ratio 8.63, 95% confidence interval 5.9112.59 and hazard ratio 3.98, 95% confidence interval 2.805.64, respectively). A 10-mu mol/l higher level of creatinine was associated with a hazard ratio of 0.56 (95% confidence interval 0.390.81) of starting use of an insulin pump. Conclusions At 10 hospital outpatient clinics in Sweden, use of insulin pumps therapy varied by clinic. A higher proportion of women began using insulin pumps. Younger patients and patients with fewer complications were also more likely to start using an insulin pump. Further research is needed to confirm these findings in other geographical regions and to understand whether the availability of insulin pumps today is optimized.

- Aims: We assessed the association between risk factors and cardiovascular disease in an observational study of patients with Type 1 diabetes from the Swedish National Diabetes Register.Methods: A derivation sample of 3661 patients, aged 30-65 years, 6.1% with previous cardiovascular disease, baseline 2002, and 197 cardiovascular disease events when followed for 5 years until 2007. A separate validation data set of 4484 patients, baseline 2003, 201 cardiovascular disease events when followed for 4 years.Results: Adjusted hazard ratios at Cox regression for fatal/non-fatal cardiovascular disease were: diabetes duration 2.76 (2.21-3.44); onset age 1.47 (1.21-1.78); log ratio total cholesterol:HDL cholesterol 1.26 (1.09-1.45); log HbA(1c) 1.19 (1.03-1.38); log systolic blood pressure 1.17 (1.01-1.34) (1 SD increase in continuous variables); smoker 1.76 (1.27-2.46); macroalbuminuria (> 200 mu g/min) 1.52 (1.10-2.10); previous cardiovascular disease 3.51 (2.54-4.84). All eight variables were used to elaborate a risk equation for 5-year cardiovascular disease risk. Regarding calibration in the derivation data set, ratio predicted 5-year risk (mean 5.4 +/- 7.9%) to observed event rate was 1.0. Discrimination was sufficient, with C-statistic 0.83, sensitivity and specificity 72 and 77%, respectively, for the top quartile of predicted risk. Similarly, calibration and discrimination were adequate in the validation data set: ratio of predicted 4-year risk/observed rate 0.94, C-statistic 0.80, sensitivity and specificity 62 and 77%, respectively, for the top quartile.Conclusions: This 5-year cardiovascular disease risk model from a large observational study of patients with Type 1 diabetes in routine care showed adequate calibration and discrimination and can be useful for clinical practice. It should also be tested in patients with Type 1 diabetes from other countries.

Tidskriftsartikel (refereegranskat)abstract
- Aim: Our aim was to investigate in a large population-based cohort study whether increased arterial stiffness and subclinical atherosclerosis in the coronary arteries differ at different stages of dysglycaemia. Methods: Data were obtained from SCAPIS, a population-based cohort of participants 50–64 years. The study population of 9379 participants was categorised according to glycaemic status: normoglycaemic, pre-diabetes (fasting glucose: 6.1–6.9 mmol/L and/or HbA1c 6%–6.4%) and diabetes. Pulse wave velocity (PWV) was measured by the SphygmoCor XCEL system and arterial stiffness was defined by PWV ≥10 m/s. Coronary artery calcium score (CACS) was assessed by coronary computed tomography and coronary artery calcification was defined by CACS ≥100. Results: We identified 1964 (21%) participants with dysglycaemia, out of which 742 (7.9%) had diabetes mellitus. PWV ≥10 m/s was present in 808 (11%), 191 (16%), 200 (27%) and CACS ≥100 in 801 (11%), 190 (16%), 191 (28%) participants with normoglycaemia, pre-diabetes and diabetes, respectively, all, p < 0.001. The overlap between PWV ≥10 m/s and CACS ≥100 within each glycaemic category was 188 (2.5%), 44 (3.6%) and 77 (10) respectively. There was an association between glycaemic status and increased PWV in the fully adjusted models, but not for glycaemic status and CACS ≥100, where there was no difference for pre-diabetes compared to normoglycaemia, OR 1.2 (95% CI 0.98–1.4). In the total study population, there was an association between HbA1c and PWV after adjustment, p < 0.001. Conclusions: Our results show that increased arterial stiffness and subclinical coronary artery atherosclerosis are present in the early stages of dysglycaemia, but the overlap between markers of major subclinical vascular damage was small in all glycaemic categories. This could be explained by different pathways in the pathogenesis of arterial stiffness or atherosclerosis in the coronary arteries.

- Aims: To report Type 2 diabetes-related outcomes after the implantation of a duodenal-jejunal bypass liner device and to investigate the role of proximal gut exclusion from food in glucose homeostasis using the model of this device. Methods: Sixteen patients with Type 2 diabetes and BMI <36kg/m2 were evaluated before and 1, 12 and 52weeks after duodenal-jejunal bypass liner implantation and 26weeks after explantation. Mixed-meal tolerance tests were conducted over a period of 120min and glucose, insulin and C-peptide levels were measured. The Matsuda index and the homeostatic model of assessment of insulin resistance were used for the estimation of insulin sensitivity and insulin resistance. The insulin secretion rate was calculated using deconvolution of C-peptide levels. Results: Body weight decreased by 1.3kg after 1week and by 2.4kg after 52weeks (P<0.001). One year after duodenal-jejunal bypass liner implantation, the mean (sem) HbA1c level decreased from 71.3 (2.4) mmol/mol (8.6[0.2]%) to 58.1 (4.4) mmol/mol (7.5 [0.4]%) and mean (sem) fasting glucose levels decreased from 203.3 (13.5) mg/dl to 155.1 (13.1) mg/dl (both P<0.001). Insulin sensitivity improved by >50% as early as 1week after implantation as measured by the Matsuda index and the homeostatic model of assessment of insulin resistance (P<0.001), but there was a trend towards deterioration in all the above-mentioned variables 26weeks after explantation. Fasting insulin levels, insulin area under the curve, fasting C-peptide, C-peptide area under the curve, fasting insulin and total insulin secretion rates did not change during the duodenal-jejunal bypass liner implantation period or after explantation. Conclusions: The duodenal-jejunal bypass liner improves glycaemia in overweight and obese patients with Type 2 diabetes by rapidly improving insulin sensitivity. A reduction in hepatic glucose output is the most likely explanation for this improvement. Diabetic Medicine © 2013 The Authors. Diabetic Medicine © 2013 Diabetes UK.

Tidskriftsartikel (refereegranskat)abstract
- AIMS: To explore the association between carotid intima-media thickness (IMT) and the apolipoprotein B (apoB)/apolipoprotein A-I (apoA-I) ratio compared with conventional lipids in middle-aged patients with Type 2 diabetes. METHODS: We analysed data from 247 patients with Type 2 diabetes, aged 55-66 years, in the Cardiovascular Risk factors in Patients with Diabetes-a Prospective study in Primary care (CARDIPP-1) study. Primary care nurses measured blood pressure and anthropometric characteristics. Blood samples were taken for laboratory analyses. The carotid IMT was determined by ultrasonography at the University Hospital in Linköping and at the County Hospital Ryhov, Jönköping, Sweden. RESULTS: The ApoB/apoA-I ratio (r = 0.207, P = 0.001), apoB (r = 0.166, P = 0.009) and non-high-density lipoprotein cholesterol (non-HDL-c) (r = 0.129, P = 0.046) correlated with IMT. Conventional lipids, high-sensitivity C-reactive protein (hsCRP), glycated haemoglobin (HbA(1c)) and systolic blood pressure were not significantly correlated to IMT. A stepwise logistic regression analysis was conducted with IMT as the dependent variable and the apoB/apoA-I ratio, HbA(1c), hsCRP, low-density lipoprotein cholesterol (LDL-c), total cholesterol, non-HDL-c and treatment with statins as independent variables. Following adjustment for age and gender, only the apoB/apoA-I ratio remained significantly associated with IMT (odds ratio 4.3, 95% confidence intervals 1.7-10.8, P = 0.002). CONCLUSIONS: We conclude that there was a significant association between the apoB/apoA-I ratio and IMT in middle-aged patients with Type 2 diabetes. The association was independent of conventional lipids, hsCRP, glycaemic control and use of statins.

- Aims In a cohort of men and women with Type 1 diabetes, prospectively followed for > 20 years, vibrotactile sense in fingers was investigated and related to neurophysiological tests, glycaemic level and clinical score. Methods Out of 58 patients, diagnosed at the age of 15-25 years and recruited 1984-1985, 32 patients (13 women, median age 52 years, range 44-75 years; 19 men, median age 52 years, range 39-69 years; median duration 33.5 years, range 21-52 years) accepted follow-up in 2006. Vibration thresholds were measured in finger pulps of index and little fingers bilaterally at seven frequencies and related to results of touch (monofilaments), tactile discrimination (two-point discrimination test), electrophysiology (median nerve function), glycaemic level (HbA(1c) levels since 1984-1985) and a clinical score. Results Vibrotactile sense was reduced in finger pulps, mainly in men, compared with an age-and gender-matched healthy control group with normal HbA(1c). Vibration thresholds were increased, particularly at 250 and 500 Hz, in both index and little finger pulps. Touch and tactile discrimination correlated with vibration thresholds, but not with each other or with electrophysiology. HbA(1c) levels (at follow-up or mean values from five follow-ups since recruitment) did not correlate with any nerve function variables. Clinical scores correlated with vibrotactile sense, particularly at higher frequencies (> 125 Hz), but not with total Z-scores of electrophysiology. Duration of disease did not correlate with any variables. Conclusions Examination of vibration thresholds in index and little finger pulps may be valuable to detect neuropathy, where thresholds correlate with symptoms and tests.

- Aims To investigate vibrotactile sense (large fibre neuropathy) at different frequencies in index and little fingers (median and ulnar nerves, respectively) of subjects with diabetes, or impaired (IGT) or normal glucose tolerance (NGT). Methods Vibration thresholds (tactilometry at seven frequencies (8, 16, 32, 64, 125, 250 and 500 Hz)) and median nerve function (electrophysiology) were examined in men (age 73.4 +/- 0.12 years; n = 58, mean +/- sd) with persistent NGT (n = 28) or IGT (n = 7) or with Type 2 diabetes mellitus (T2DM) (n = 23) for > 15 years. Results HbA(1c) was increased and vibrotactile sense (sensibility index) was impaired in index and little fingers in men with T2DM. Vibration thresholds were particularly increased at 16, 250 and 500 Hz in the little finger (ulnar nerve). T2DM subjects showed electrophysiological (gold standard) signs of neuropathy in the median nerve. Although subjects with persistent IGT had higher HbA(1c), vibrotactile sensation and electrophysiology remained normal. HbA(1c) did not correlate with vibrotactile sense or electrophysiology, but the latter two correlated with respect to Z-score (sign of neuropathy) in forearm (NGT) and at wrist level (NGT and DM). Conclusions Vibration thresholds are increased in the finger pulps in T2DM subjects, particularly at specific frequencies in ulnar nerve innervated finger pulps. Neuropathy is not present in IGT. Tactilometry, with a multi-frequency approach, is a sensitive technique to screen for large fibre neuropathy in T2DM. Frequency-related changes may mirror dysfunction of various receptors.

- Aim: To determine whether pregnancy-associated plasma protein-A2 levels are increased in early pregnancies complicated by gestational diabetes and whether gestation age influences levels. The possible use of pregnancy-associated plasma protein-A2 as a pre-screening biomarker to reduce the need for performing oral glucose tolerance tests in pregnant women was also investigated. Methods: Pregnant women were diagnosed with gestational diabetes in early pregnancy after a 2-hour 75 g oral glucose tolerance test in the catchment area of Skåne University Hospital, Lund, Sweden during 2011–2015 (n = 99). Age- and BMI-matched pregnant women without diabetes were recruited at similar gestational ages from maternal healthcare centres in the same geographical area during 2014–2015 to act as controls (n = 100). Circulating pregnancy-associated plasma protein-A2 was analysed in participant serum using commercially available enzyme-linked immunosorbent assay kits. Results: Circulating pregnancy-associated plasma protein-A2 was increased in women diagnosed with gestational diabetes [13.5 (9.58–18.8) ng/ml] compared with controls [8.11 (5.74–11.3) ng/ml; P < 0.001]. Pregnancy-associated plasma protein-A2 was associated with gestational diabetes independent of age, BMI, C-peptide and adiponectin (P < 0.001). Pregnancy-associated plasma protein-A2 as a pre-screening biomarker to identify women at a decreased risk of gestational diabetes resulted in a negative predictive value of 99.7%, with a sensitivity of 96% and a specificity of 30% at a cut-off level of 6 ng/ml. Conclusions: This is the first study to show increased pregnancy-associated plasma protein-A2 levels in gestational diabetes. Pregnancy-associated plasma protein-A2 also shows promise as a pre-screening biomarker with the potential to reduce the need for performing oral glucose tolerance tests in early pregnancy. Future prospective cohort studies in a larger group of both high- and low-risk women are, however, needed to further confirm this observation.

Prevalence of zinc transporter 8 antibodies in gestational diabetes mellitus.

Tidskriftsartikel (refereegranskat)abstract
- Aims: Gestational diabetes mellitus affects approximately 7% of all pregnant women. Some of these women develop autoantibodies that are generally characteristic of Type 1 diabetes. Autoantibodies targeting glutamic acid decarboxylase and tyrosine phosphatase-like protein are the most frequently reported. A recently identified autoantigen in Type 1 diabetes is zinc transporter 8. Some reports suggest that the frequency of zinc transporter 8 antibodies is as high as glutamic acid decarboxylase antibodies in Type 1 diabetes and thus a good diagnostic marker for autoimmune diabetes. There are currently no reports of zinc transporter 8 antibodies in gestational diabetes. The aim of this pilot study was to investigate the frequency of zinc transporter 8 antibodies in patients at clinical onset of gestational diabetes mellitus. Methods: Subjects included in this pilot study were all diagnosed with gestational diabetes at Skåne University Hospital, Lund, Sweden, 2009-2010 (n = 193). Sera samples were analysed for antibodies using a commercial enzyme-linked immunosorbent assay according to the manufacturers' instructions. Results: We found that 19/193 patients with gestational diabetes, diagnosed in 2009-2010, were positive for at least one autoantibody. Glutamic acid decarboxylase was the most common single autoantibody (52.6%; 10/19), followed by zinc transporter 8 (21.1%; 4/19) and tyrosine phosphatase-like protein (15.8%; 3/19). Combinations of two or more antibodies were rare (10.5%; 2/19). Conclusions: In this study, we found that zinc transporter 8 added 2.1% (4/193) of autoantibody positivity in women with gestational diabetes who were negative for glutamic acid decarboxylase and tyrosine phosphatase-like protein antibodies. Glutamic acid decarboxylase was still the most prevalent autoantibody in gestational diabetes, but, as zinc transporter 8 was present even in the absence of glutamic acid decarboxylase, this autoantibody could be an important independent marker of autoimmunity in gestational diabetes. © 2012 The Authors.

- AIMS: To study clinical presentation, in-hospital course and short-term prognosis in men and women with diabetes mellitus and acute coronary syndromes (ACS). METHODS: Men (n = 6488, 21.2% with diabetes) and 2809 women (28.7% with diabetes) < or = 80 years old, with a discharge diagnosis of ACS were prospectively enrolled in the Euro Heart Survey of ACS. RESULTS: Women with diabetes were more likely to present with ST elevation than non-diabetic women, a difference that became more marked after adjustment for differences in smoking, hypertension, obesity, medication and prior disease [adjusted odds ratio (OR) 1.46 (1.20, 1.78)], whereas there was little difference between diabetic and non-diabetic men [adjusted OR 0.99 (0.86, 1.14)]. In addition, women with diabetes were more likely to develop Q-wave myocardial infarction (MI) than non-diabetic women [adjusted OR 1.61 (1.30, 1.99)], while there was no difference between men with and without diabetes [adjusted OR 0.99 (0.85, 1.15)]. There were significant interactions between sex, diabetes and presenting with ST-elevation ACS (P < 0.001), and Q-wave MI (P < 0.001), respectively. Of the women with diabetes, 7.4% died in hospital, compared with 3.6% of non-diabetic women [adjusted OR 2.13 (1.39, 3.26)], whereas corresponding mortality rates in men with and without diabetes were 4.1% and 3.3%, respectively [OR 1.13 (0.76, 1.67)] (P for diabetes-sex interaction 0.021). CONCLUSION: In women with ACS, diabetes is associated with higher risk of presenting with ST-elevation ACS, developing Q-wave MI, and of in-hospital mortality, whereas in men with ACS diabetes is not significantly associated with increased risk of either. These findings suggest a differential effect of diabetes on the pathophysiology of ACS based on the patient's sex.

- AIM: To investigate risk factors for the development of diabetes in middle-aged women. METHODS: A random population sample of 1351 women without prior diabetes or cardiovascular disease, aged 39-65 years, took part in a screening study in 1979-1981 with questionnaires, physical examination and blood sampling. Development of diabetes up to 1998 was identified at a second examination in 1997-1998. RESULTS: Seventy-three women (5.4%) were diagnosed with diabetes during follow-up. As expected, obesity resulted in a rising age-adjusted risk with hazards ratio 3.2 [95% confidence interval (CI) 1.3, 8.1] at body mass index (BMI) 24-27 kg/m(2), and 8.3 (3.5, 19.7), at BMI > or = 27, compared with BMI < 22 kg/m(2). S-triglycerides (TG) carried a steeply increasing age-adjusted risk with hazards ratio 4.0 (95% CI 2.1, 7.6) already at s-TG 1.0-1.4 mmol/l, 7.1 (3.6, 14.0) at s-TG 1.5-1.9 mmol/l and 9.3 (4.3, 20.2) at s-TG > or = 2.0 mmol/l compared with s-TG < 1.0 mmol/l. Increasing systolic blood pressure (SBP) to 130-144, 145-159 and > or = 160 mmHg escalated the hazards ratio of diabetes to 1.6 (0.8, 3.3), 3.6 (1.7, 7.4) and 5.6 (2.7, 11.4), respectively, compared with SBP < 130 mmHg. Also, low physical activity predicted diabetes, with hazards ratio 2.1 (1.3, 3.3) for sedentary compared with non-sedentary activity. Smoking was not associated with increased risk of diabetes. After adjustment for BMI, SBP and physical activity, increasing TG level remained a strong and significant risk factor for diabetes [hazards ratio 3.0 (1.6, 5.7), 3.7 (1.8, 7.7) and 4.5 (2.0, 10.0), P < 0.001]. CONCLUSIONS: Among middle-aged Swedish women even very slightly elevated s-TG resulted in a considerably enhanced risk of developing diabetes, which was independent of age, BMI, blood pressure and physical activity.

- Aim The aim of this observational study was to investigate relationships between physiological levels of glucometabolic biomarkers and cognitive test results in a population-based setting. Methods Cross-sectional data were obtained from the Swedish population-based Malmo Diet and Cancer Study Re-examination 2007-2012 comprising 3001 older people (mean age 72 years). Through oral glucose tolerance testing (OGTT), fasting and post-load levels of serum insulin, plasma glucagon, serum glucose-dependent insulinotropic peptide (GIP) and plasma glucagon-like peptide-1 (GLP-1) were measured. Insulin resistance and insulin sensitivity levels were calculated. In 454 participants, advanced glycation end products (AGEs) were estimated through skin autofluorescence. Associations between biomarkers and two cognitive tests, the Mini-Mental State Examination (MMSE) and A Quick Test of Cognitive Speed (AQT) respectively, were explored in multiple regression analyses. Results Positive associations following adjustments for known prognostic factors were found between MMSE scores and insulin sensitivity (B = 0.822, P = 0.004), 2-h plasma glucagon (B = 0.596, P = 0.026), 2-h serum GIP (B = 0.581, P = 0.040) and 2-h plasma GLP-1 (B = 0.585, P = 0.038), whereas negative associations were found between MMSE scores and insulin resistance (B = -0.734, P = 0.006), fasting plasma GLP-1 (B = -0.544, P = 0.033) and AGEs (B = -1.459, P = 0.030) were found. Conclusions Higher levels of insulin sensitivity, GIP and GLP-1 were associated with better cognitive outcomes, but AGEs were associated with worse outcomes, supporting evidence from preclinical studies. Glucagon was linked to better outcomes, which could possibly reflect neuroprotective properties similar to the related biomarker GLP-1 which has similar intracellular properties. Longitudinal and interventional studies are needed to further evaluate neuromodulating effects of these biomarkers. presented at the European Association for the Study of Diabetes (EASD) 2019, Barcelona, Spain

- Aims There are few cohorts of type 1 diabetes that follow individuals over more than half a century in terms of health outcomes. The aim of this study was to examine associations between type 1 diabetes, diagnosed before age 18, and long-term morbidity and mortality, and to investigate whether cognitive ability plays a role in long-term morbidity and mortality risk. Methods In a Swedish cohort, 120 men with type 1 diabetes and 469 without type 1 diabetes were followed between 18 and 77 years of age as regards morbidity and mortality outcomes, and impact of cognitive ability at military conscription for the outcomes. In Cox regression analyses and Kaplan-Meier analyses with log-rank tests, associations between diabetes and cognitive ability respectively, and outcomes (mortality, cardiovascular morbidity and diabetes complications) were investigated. Results Men with type 1 diabetes suffered from dramatically higher mortality (HR 4.62, 95% CI: 3.56-5.60), cardiovascular mortality (HR 5.60, 95% CI: 3.27-9.57), and cardiovascular events (HR 3.97, 95% CI: 2.79-5.64) compared to men without diabetes. Higher cognitive ability at military conscription was associated with lower mortality in men without diabetes, but was not associated with any outcome in men with diabetes. Conclusions In this historical cohort study with 60 years of follow-up time and a less effective treatment of diabetes than today, mortality rates and cardiovascular outcomes were high for men with type 1 diabetes. Morbidity or mortality did not differ between those that had low to normal or high cognitive ability among men with type 1 diabetes.

- Aims Intermittent claudication is common in diabetes mellitus. However, a proportion of patients with diabetes have symptoms of claudication without signs of vascular disease and these patients were evaluated for chronic exertional compartment syndrome. Methods Forty-two patients with diabetes (10 men, 32 women), earlier investigated at diabetic clinics because of claudication with no explanation for the symptoms, were examined. Their median age was 48 years (18–72 years) and the median duration of diabetes was 29 years (1–45 years). Thirty-one patients had Type 1 diabetes, 11 had Type 2 diabetes and 29 had diabetic complications. All were investigated clinically, with radiography, bone scan and intramuscular pressure measurements. Results Thirty-eight of 42 patients with diabetes were diagnosed with chronic exertional compartment syndrome of the lower leg and 32 were treated surgically. Thirty-one patients were operated with fasciotomy of the anterior compartment and 18 also with fasciotomy of the posterior compartment. Additionally, one patient had only fasciotomy of the posterior compartment. Fourteen of 32 surgically treated patients (27 legs) were followed for more than 2 years and rated the post-operative outcome as excellent or good in 21 of the treated legs. The walking distance before lower leg pain increased in all but one patient and seven patients reported unrestricted walking ability. Conclusions Chronic exertional compartment syndrome should be considered as a differential diagnoses in patients with diabetes and exercise-related lower leg pain. The results after surgery are encouraging and the increased walking ability is beneficial in the treatment of diabetes.

- Aims Genetic testing is needed for the formal diagnosis of maturity-onset diabetes of the young (MODY), but this is not widely available. If any MODY biomarkers were known, these could possibly be used as an alternative. Hepatocyte nuclear factor (HNF)-1alpha and HNF-4alpha regulate transcription of genes encoding complement 5 (C5), complement 8 (C8) and transthyretin (TTR), suggesting that these could be potential biomarkers for the disease. We therefore set out to determine whether serum concentrations of C5, C8 and TTR can be used as biomarkers for patients with HNF4A-MODY and HNF1A-MODY. Methods The serum concentrations of C5, C8 and TTR were analysed in patients with mutations in the HNF-1alpha (n = 29) and EtaNuF-4alpha (n = 13) genes. Type 2 diabetic (n = 14) and healthy subjects (n = 20), matched for body mass index (BMI), served as diabetic and non-diabetic control groups, respectively. Results Type 2 diabetic patients had markedly increased levels of C5 and C8 compared with healthy control subjects. Levels of C5 and C8 correlated with glycated haemoglobin (C5: r = 0.48, P = 0.019). After adjustment for BMI, glycated haemoglobin, age and gender, HNF4A-MODY and HNF1A patients had reduced levels of C5 and C8 compared with Type 2 diabetic patients (C5: P = 0.001; C8: P = 0.004). In addition, patients with HNF4A-MODY, but not those with HNF1A-MODY, had decreased TTR compared with diabetic patients (P = 0.038). Conclusions Serum concentrations of C5 and C8 seem to distinguish HNF4A and HNF1A-MODY from other forms of diabetes. However, hyperglycaemia per se increases the serum concentrations, thereby attenuating their potential role as biomarkers for MODY.

- Aims: We investigated the long-term temporal trend of intraepidermal nerve fibre density (IENFD) and the association between changes in IENFD and metabolic factors in individuals with and without type 2 diabetes. Methods: A total of 66 participants were enrolled in this longitudinal population-based study, at baseline consisting of 35 individuals (median 61 years) without diabetes and 31 individuals with type 2 diabetes mellitus. Participants underwent clinical and electrophysiological examinations, as well as a skin biopsy both at baseline and at the follow-up visit (mean 8.1 ± 0.5 years). IENFD was assessed in thin sections of 5 μm, stained with the protein gene product 9.5-antibody and compared between the groups. Results: IENFD decreased during the period in both groups, with a greater decline in the group without diabetes than in type 2 diabetes (−2.3 and −0.6 fibres/mm respectively; p < 0.001). While IENFD at baseline was significantly reduced in type 2 diabetes relative to people without (p < 0.001), no difference in IENFD was found between groups at the follow-up (p = 0.183). Linear mixed model analysis indicated that age, weight and HbA1c were associated with decrease in IENFD in the total population (p < 0.007). IENFD also decreased with increasing age and weight, but not with HbA1c, in the separate groups (p < 0.049). Conclusions: Despite lower IENFD levels at baseline in type 2 diabetes, IENFD was equal between the groups at follow-up. A decrease in IENFD is to a limited extent affected by body weight, and HbA1c, but age seems to be the long-term determinant of IENFD in an elderly population.

- Guidelines for the treatment of risk factors in diabetes care have been updated recently, due to indisputable results from clinical end-point trials. This study evaluates risk factor control compared with current national and international targets during the period 1996-2003 in Type 2 diabetes (DM2). Patients were registered in primary-care and hospital outpatient clinics using computer software, or via the Internet. The clinical characteristics of the patients, treatment, HbA(1c), and risk factors were reported after screening by local methods. The numbers of cases of DM2 reported were 17547 in 1996 and 57119 in 2003. The mean HbA(1c) decreased from 7.8 to 7.2%, while blood pressure decreased from 150/82 to 143/78 mmHg during the same period. Longitudinal analysis of results was performed in 5356 patients repeatedly reported, showing slightly lower effects. The new European treatment targets of HbA(1c)< or = 6.1%, blood pressure < 130/80 mmHg and total cholesterol < 4.5 mmol/l were attained by 16, 13 and 28% of the patients in 2003, respectively. The prevalence of the metabolic syndrome in 2003 was 77%. Aspirin was prescribed in 36% of cases. Lipid-lowering, anti-hypertensive drugs, and treatment with oral hypoglycaemic agents in combination with insulin were increasingly employed during the period studied. Risk factor control in DM2 reported to the National Diabetes Register (NDR) is slowly improving, although multiple risk factors and the metabolic syndrome are found in most patients. The majority of subjects do not achieve current target levels for HbA(1c), blood pressure and blood lipids. Thus, giving up smoking and increased use of aspirin are called for, as well as more aggressive treatment of hyperglycaemia, elevated blood pressure and blood lipid levels, in accordance with updated international guidelines.

- AimTo investigate whether intensive multifactorial treatment can reverse the predisposed adverse phenotype of people with Type 2 diabetes who have a family history of diabetes. MethodsData from the randomized controlled trial ADDITION-Denmark were used. A total of 1441 newly diagnosed patients with diabetes (598 with family history of diabetes) were randomized to intensive treatment or routine care. Family history of diabetes was defined as having one parent and/or sibling with diabetes. Linear mixed-effects models were used to assess the changes in risk factors (BMI, waist circumference, blood pressure, lipids and HbA(1c)) after 5years of follow-up in participants with and without a family history of diabetes. An interaction term between family history of diabetes and treatment group was included in the models to test for a modifying effect of the intervention. All analyses were adjusted for age, sex, baseline value of the risk factor and general practice (random effect). ResultsAt baseline, participants with a family history of diabetes were younger and had a 1.1 mmol/mol (0.1%) higher HbA(1c) concentration at the time of diagnosis than those without a family history of diabetes. Family history of diabetes modified the effect of the intervention on changes in HbA(1c) levels. In the group receiving routine care, participants with a family history of diabetes experienced an improvement in HbA(1c) concentration that was 3.3mmol/mol (0.3%) lower than the improvement found in those without a family history of diabetes after 5years of follow-up. In the intensive treatment group, however, there was no difference in HbA(1c) concentrations between participants with and without a family history of diabetes after 5years of treatment. ConclusionsIntensive treatment of diabetes may partly remove the adverse effects of family history of diabetes on glycaemic control. The effect of this improvement on long-term diabetic complications warrants further investigation. What's new? People with Type 2 diabetes who have a family history of diabetes have worse glycaemic control than those with Type 2 diabetes without a family history of diabetes. Intensive multifactorial treatment, but not routine clinical care, partly removes the adverse effects of family history of diabetes on glycaemic control.

- AimTo investigate whether reduced lung function is a risk factor for developing diabetes. MethodsNon-diabetic men (n = 382) from the population-based cohort 'Men Born in 1914' were examined with spirometry at age 55 years. The cohort was re-examined at 68 years. Diabetes and fasting plasma glucose at follow-up were studied in relation to vital capacity (VC) and forced expiratory volume (FEV1.0) at baseline. ResultsFifteen men developed diabetes during the follow-up. The percentage with diabetes in the 1st, 2nd, 3rd and top quartile of vital capacity were 7%, 5%, 2%, and 1%, respectively (P for trend = 0.01). Fasting glucose (log transformed, mmol/l) at follow-up was 1.63 ± 0.16, 1.62 ± 0.18, 1.61 ± 0.11 and 1.60 ± 0.11, respectively (P for trend = 0.11). The longitudinal associations between VC and diabetes (P = 0.001) and log glucose (P = 0.036) were significant after adjustments for several potential confounders. FEV1.0 at baseline showed similar associations with diabetes at follow-up. ConclusionsThe risk of developing diabetes is inversely associated with pulmonary function among middle-aged men.
