Tidskriftsartikel (refereegranskat)abstract
- The Goto-Kakizaki (GK) rat represents a model of hereditary non-insulin-dependent diabetes mellitus (NIDDM), characterized by nonobesity, mild hyperglycemia from early life, impaired glucose tolerance test results, and a markedly defective insulin response to glucose. The rats develop signs of both nephropathy and neuropathy, but, to our knowledge, retinal changes have not been reported so far in this model of NIDDM. Hence, the aim of the present study was to assess whether morphological vascular changes could be demonstrated in retinal vessel preparations of GK rats. The endothelial/pericyte ratio was found to be higher in GK rats aged 8 months as well as after 24-30 months compared to their matched controls (2.3 +/- 0.2 versus 2.0 +/- 0.1; p < 0.01, and 2.6 +/- 0.2 versus 1.9 +/- 0.1; p < 0.001, respectively). Furthermore, in 24 to 30-months-old GK rats, the endothelial/pericyte ratio was higher than in 8 month old GK rats (p < 0.05). Thus, the GK rat appears to be a suitable model for experimental studies of chronic complications, including diabetic retinopathy, in NIDDM.

Tidskriftsartikel (refereegranskat)abstract
- Fifty-six type I diabetic patients with microalbuminuria (albumin excretion rate 20-200 micrograms/min) were characterized as to sex, age, duration of diabetes, smoking habits, blood pressure, glomerular filtration rate, urinary NC1 (the carboxy-terminal domain of collagen IV), and Tamm-Horsfall protein excretion rate. Albumin excretion rate was considered a sign of glomerular damage, NC1 excretion rate a measure of renal basement membrane turnover, and Tamm-Horsfall protein excretion rate a marker for distal tubular function. There were no differences between males and females and between smokers and nonsmokers with respect to blood pressure, body-mass index, albumin excretion rate, glomerular filtration rate, excretion rate of NC1, and Tamm-Horsfall protein. As a group, the patients with microalbuminuria had normal glomerular filtration rate, excretion rate of NC1, and Tamm-Horsfall protein. The latter was influenced by glycosylated hemoglobin (HbA1c) levels, especially so in patients with an albumin excretion rate less than the median value of 53.0 micrograms/min (r = -0.61, p < 0.01). Furthermore, both excretion rate of NC1 and Tamm-Horsfall protein were increased in patients with high glomerular filtration rate > or = 130 mL min-1 1.73 m-2). There was no association between glomerular filtration rate and HbA1c levels. As glomerular filtration rate is related to kidney size, these observations suggest that patients with a high glomerular filtration rate have an increased mass and turnover of tubular basement membrane.(ABSTRACT TRUNCATED AT 250 WORDS)

Tidskriftsartikel (refereegranskat)abstract
- To describe the impact of a history of diabetes mellitus on the improvement of symptoms and various aspects of quality of life (QoL) during 5 years after coronary artery bypass grafting (CABG). Patients who underwent CABG between 1988 and 1991 in western Sweden were approached with an inquiry prior to surgery and 5 years after the operation. QoL was estimated with three different instruments: Physical Activity Score (PAS), Nottingham Health Profile (NHP) and Psychological General Well-Being (PGWB) index. 876 patients participated in the evaluation, of whom 87 (10%) had a history of diabetes. Symptoms of dyspnea and chest pain improved both in diabetic and non-diabetic patients. Diabetic patients scored worse than non-diabetic patients both prior to and 5 years after CABG, but without any major difference in improvement between the two groups with all three measures of QoL. PAS tended to improve more in non-diabetic than in diabetic patients, whereas improvement in NHP and PGWB was similar regardless of a history of diabetes. Diabetic patients differ from non-diabetic patients having an inferior QoL both prior to and 5 years after CABG. Both diabetic and non-diabetic patients improve in symptoms and QoL after the operation. In some aspects improvement tended to be less marked in the diabetic patients but on the whole improvement was similar compared to non-diabetic patients.

Tidskriftsartikel (refereegranskat)abstract
- Two common complaints related to diabetes mellitus are oral dryness (xerostomia) and peripheral neuropathy (PN) and there is some evidence of a relationship between them. Therefore, we formulated a hypothesis that type 2 diabetic subjects with xerostomia in our study also exhibited PN. The study included 102 randomly sampled type 2 diabetic patients from a healthcare district in mid-Sweden. Besides clinical and X-ray examinations, patients were asked whether they experienced oral dryness. PN was defined through thorough foot examination and the use of a modified neuropathy symptom score (NSS) and neuropathy disability score (NDS). Other diabetes-related variables were extracted from medical records. More than half of the individuals (53.5%) reported oral dryness and 23.8% were diagnosed with PN. None of the variables in a stepwise regression analysis could explain the variance in oral dryness, besides "pain in the legs," which contributed with 5% to the explanation. Our hypothesis that type 2 diabetic subjects with xerostomia also were affected with PN could not be verified in this study, but the results must be interpreted with caution as relatively few subjects were affected with both oral dryness and PN (13.8%). Further and larger controlled studies are needed before the hypothesis can be definitely rejected. Despite our incomplete understanding about the relation between oral dryness and PN, professionals in oral health as well as in primary health have to strive for increased knowledge in this field. ⌐ 2003 Elsevier Inc.

Tidskriftsartikel (refereegranskat)abstract
- AIM: To examine the prevalence and the clinical characteristics associated with normoalbuminuric renal impairment (RI) in a general type 2 diabetes (T2D) population. METHODS: We included 94 446 patients with T2D (56% men, age 68.3±11.6years, BMI 29.6±5.3kg/m(2), diabetes duration 8.5±7.1years; means±SD) with renal function (serum creatinine) reported to the Swedish National Diabetes Register (NDR) in 2009. RI was defined as estimated glomerular filtration (eGFR)<60ml/min/1.73m(2) and albuminuria as a urinary albumin excretion rate (AER)>20μg/min. We linked the NDR to the Swedish Prescribed Drug Register, and the Swedish Cause of Death and the Hospital Discharge Register to evaluate ongoing medication and clinical outcomes. RESULTS: 17% of the patients had RI, and 62% of these patients were normoalbuminuric. This group of patients had better metabolic control, lower BMI, lower systolic blood pressure and were more often women, non-smokers and more seldom had a history of cardiovascular disease as compared with patients with albuminuric RI. 28% of the patients with normoalbuminuric RI had no ongoing treatment with any RAAS-blocking agent. Retinopathy was most common in patients with RI and albuminuria (31%). CONCLUSIONS: The majority of patients with type 2 diabetes and RI were normoalbuminuric despite the fact that 25% of these patients had no ongoing treatment with RAAS-blocking agents. Thus, RI in many patients with type 2 diabetes is likely to be caused by other factors than diabetic microvascular disease and ongoing RAAS-blockade.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this Phase II study was to evaluate if alum-formulated human recombinant GAD65 is safe and does not compromise beta cell function. The study was conducted as a randomized, double blind, placebo-controlled, dose-escalation clinical trial in a total of 47 Latent Autoimmune Diabetes in Adults (LADA) patients who received either placebo or 4, 20, 100, or 500 μg Diamyd subcutaneously at Weeks 1 and 4. Safety evaluations, including neurology, beta cell function tests, diabetes status assessment, hematology, biochemistry, and cellular and humoral immunological markers, were repeatedly assessed over 24 weeks. None of the patients had significant study-related adverse events (AE). Fasting c-peptide levels at 24 weeks were increased compared with placebo (P=.0015) in the 20 μg but not in the other dose groups. In addition, both fasting (P=.0081) and stimulated (P=.0236) c-peptide levels increased from baseline to 24 weeks in the 20 μg dose group. GADA log levels clearly increased (P=.0002) in response to 500 μg Diamyd. The CD4+CD25+/CD4+CD25− cell ratio increased (P=.0128) at 24 weeks in the 20 μg group. No sudden increase in HbA1c or plasma glucose or decrease in beta cell function was observed in any of the dose groups. These positive findings for clinical safety further support the clinical development of Diamyd as a therapeutic to prevent autoimmune diabetes.

- Aims: To evaluate how HbA1c in adolescents with type 1 diabetes affects microvascular complications in young adults. Methods: All individuals registered in the Swedish paediatric diabetes quality registry (SWEDIABKIDS) 13-18 years of age, and as adults registered in the Swedish National Diabetes Registry (NDR) in both the years 2011 and 2012 were included, in total 4250 individuals. Results: Of the individuals with mean HbA1c >78 mmol/mol in SWEDIABKIDS 83.4% had retinopathy, 15.8% had microalbuminuria and 4.9% had macroalbuminuria in NDR. The logistic regression analysis showed that the OR to develop macroalbuminuria as a young adult was significantly higher in the group with mean HbA1c >78 mmol/mol in SWEDIABKIDS (p < 0.05). Among the patients with mean HbA1c above 78 mmol/mol in both registries there was a significantly higher proportion that had retinopathy, microalbuminuria (p < 0.001) and/or macroalbuminuria (p < 0.01) compared to the group with HbA1c below 57 mmol/mol in both registries. Only 6.5% of the persons in this study were over 30 years of age. Conclusions: Paediatric diabetes teams working with teenagers must be aware of the impact of good metabolic control during adolescence, and should intensify the care during this vulnerable period of life to reduce the risk of microvascular complications in young adults.

- OBJECTIVE: Patients with type 1 diabetes (T1D) have an increased risk of cognitive dysfunction. The cognitive decrement is believed to depend on macro- and microvascular complications and long disease duration. Some patients do not develop these complications, but still report cognitive symptoms. We examined if long-standing T1D without complications is associated with lower cognitive performance.METHODS: A group of patients (n=43) with long-standing T1D (>30years) without micro- or macro vascular complications was compared with a non-diabetic control group (n=86) on six cognitive tests which probed episodic memory, semantic memory, episodic short-term memory, visual attention and psychomotor speed. Each patient was matched with two controls regarding age, gender and education. A linear mixed effect model was used to analyze the data.RESULTS: The mean age was 57years and mean duration was 41years. Patients with diabetes had lower diastolic blood pressure but BMI, waist circumference, systolic blood pressure and smoking did not differ between groups. Patients had lower results than non-diabetic controls in episodic short-term memory (p<0.001) and also lower values on a test that mirrors visual attention and psychomotor speed (p=0.019).CONCLUSIONS: Long-standing T1D was associated with lower cognitive performance, regardless of other diabetes-related complications.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: This study aimed to investigate circulating biomarkers associated with the risk of developing diabetic peripheral neuropathy (DPN) and nephropathy in type 1 diabetes (T1D).MATERIALS AND METHODS: Patients with childhood-onset T1D (n = 49, age 38.3 ± 3.8 yrs.) followed prospectively were evaluated after 30 years of diabetes duration. DPN was defined as an abnormality in nerve conduction tests. Matrix metalloproteinase-9 (MMP-9) and its tissue inhibitor TIMP-1, neutrophil gelatinase-associated lipocalin-2 (NGAL), soluble P-selectin (sP-selectin), estimated GFR (eGFR), micro/macroalbuminuria and routine biochemistry were assessed. For comparison, control subjects were included (n = 30, age 37.9 ± 5.5 yrs.).RESULTS: In all, twenty-five patients (51 %) were diagnosed with DPN, and nine patients (18 %) had nephropathy (five microalbuminuria and four macroalbuminuria). Patients with DPN had higher levels of TIMP-1 (p = 0.036) and sP-selectin (p = 0.005) than controls. Patients with DPN also displayed higher levels of TIMP-1 compared to patients without DPN (p = 0.035). Patients with macroalbuminuria had kidney disease stage 3 with lower eGFR, higher levels of TIMP-1 (p = 0.038), and NGAL (p = 0.002). In all patients, we found only weak negative correlations between eGFR and TIMP-1 (rho = -0.304, p = 0.040) and NGAL (rho = -0.277, p = 0.062, ns), respectively. MMP-9 was higher in patients with microalbuminuria (p = 0.021) compared with normoalbuminuric patients.CONCLUSIONS: Our findings indicate that TIMP-1 and MMP-9, as well as sP-selectin and NGAL, are involved in microvascular complications in T1D. Monitoring and targeting these biomarkers may be a potential strategy for treating diabetic nephropathy and neuropathy.

Tidskriftsartikel (refereegranskat)abstract
- Background: Diabetes is associated with increased risk of a spectrum of cancers, but there are few meta-analyses on the association between diabetes and kidney cancer. We performed a meta-analysis of case-control studies and cohort studies to address the incidence and mortality of kidney cancer in diabetes. Methods: Studies were identified by searching PubMed database and manual assessment of the cited references in the retrieved articles. Study-specific relative risks (RRs) and 95% confidence intervals (CIs) were estimated using a random-effect model. Study quality was assessed using the Newcastle-Ottawa scale. Results: A total of 24 studies were included. We found that diabetes was significantly associated with increased risk of kidney cancer (RR=1.40, 95% CI = 1.16 to 1.69), and the results were consistent between case-control and cohort studies. A slightly stronger positive relation was observed in women (RR = 1.47, 95% CI=1.18 to 1.83) than in men (RR=1.28, 95% CI=1.10 to 1.48). Additional analyses indicated that the increased risk of kidney cancer was independent of alcohol consumption, body mass index (BMI)/obesity and smoking. However, there was no association between diabetes and mortality of kidney cancer (RR=1.12, 95% CI=0.99 to 1.20), without heterogeneity (P = 0.419, I-2 = 1.8%). Conclusions: Diabetes mellitus may increase the risk of kidney cancer in both women and men.

- Aim: Impaired regulation of glucose metabolism in childhood adversely affects bone health. We assessed the effect of fasting hyperglycemia and insulin resistance on bone turnover markers in prepubertal children with normal glycemia (<100 mg/dL) and fasting hyperglycemia (100-125 mg/dL).Methods: Glucose, hemoglobin A1c, IGF-I (insulin-like growth factor I), iP1NP (N-terminal propeptide of type I procollagen), CTX-1 (C-terminal telopeptide of type I collagen) and insulin were measured. Bone turnover index (BTI) and HOMA-IR (homeostasis model assessment) were calculated.Results: Bone resorption marker (CTX) levels were decreased by 26.5% in boys with hyperglycemia, though only 7% in girls. Hyperglycemia had no effect on the bone formation marker iP1NP. IGF-1, the best predictor of bone marker variance accounted for 25% of iP1NP and 5% of CTX variance. Girls presented significantly higher BTI indicating the predominance of bone formation over resorption. Insulin resistance significantly decreased CTX. In girls, HOMA-IR and IGF-1 predicted 15% of CTX variance.Conslusions: Fasting hyperglycemia and insulin resistance in children impact bone turnover suppressing bone resorption. Hyperglycemia decreased resorption, particularly in boys, while suppression of resorption by insulin resistance was more pronounced in girls. We suggest that the progression of disturbances accompanying prediabetes, may interfere with bone modelling and be deleterious to bone quality in later life.

- AIMS/HYPOTHESIS: This study aimed to examine hand disorders, symptoms, overall hand function, activities of daily living (ADLs), and life satisfaction in elderly men with type 2 diabetes mellitus (DM), impaired glucose tolerance (IGT), and normal glucose tolerance (NGT). METHODS: Subjects were interviewed and evaluated with a battery of clinical and laboratory tests, including hand assessment, and a questionnaire. RESULTS: HbA1c differed between groups (highest in DM, especially in long-term DM). Limited joint motion (LJM), for example, prayer sign and Dupuytren's contracture, was most common in individuals with DM, followed by individuals with IGT, as compared to those with NGT. Vibrotactile sense was impaired symmetrically in the index and little fingers in DM. However, there were no differences for sensibility, dexterity, grip strength, and cold intolerance between groups. Individuals with long-term (>15 years) DM were more affected regarding sensibility and ADL than individuals with short-term DM, who had more sleep disturbances. ADL difficulties were less among IGT subjects. Vibrotactile sense showed correlations with Semmes-Weinstein monofilament test and static two-point discrimination. CONCLUSIONS/INTERPRETATION: Dupuytren's contracture and impaired vibrotactile sense in finger pulps occurred in patients with DM but not in those with IGT, although LJM occurred in both IGT and DM patients. A longer duration of DM was associated with more severe neuropathy and ADL difficulties. Life satisfaction was high, and hand disorders did not have a significant impact on ADL.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To examine patient-reported outcome (PRO) in a selected group of Swedish patients about to receive anti-vascular endothelial growth factor (VEGF) treatment for diabetic macular edema (DME). Material and methods: In this cross-sectional study, 59 patients with diabetes mellitus, who regularly visited the outpatient eye-clinics, were included. Sociodemographic and clinical data were collected and the patients completed PRO measures before starting anti-VEGF treatment. PRO measures assessed eye-specific outcomes (NEI-VFQ-25) and generic health-related quality of life (SF-36). Results: The participants consisted of 30 men and 29 women (mean age, 68.5 years); 54 (92%) patients had type 2 diabetes; 5 (9%) patients had moderate or severe visual impairment; 28 (47%) were classified as having mild visual impairment. Some of the patients reported overall problems in their daily lives, such as with social relationships, as well as problems with impaired sight as a result of reduced distance vision. Conclusions: Further studies are needed to investigate PRO factors related to low perceived general health in this patient population. It is important to increase our understanding of such underlying mechanisms to promote improvements in the quality of patient care.

IGF2BP2 and IGF2 genetic effects in diabetes and diabetic nephropathy
- 2012
-
Ingår i: Journal of diabetes and its complications. - : Elsevier BV. - 1056-8727 .- 1873-460X. ; 26:5, s. 393-398

Tidskriftsartikel (refereegranskat)abstract
- Objective: The IGF2BP2 gene is located on chromosome 3q27.2 within a region linked to type 1 diabetes (T1D), type 2 diabetes (120) and diabetic nephropathy (ON). Its protein functionally binds to 5'-UTR of the imprinting IGF2 gene. The present study aims to evaluate the IGF2BP2-IGF2 genetic effects in diabetes and DN. Materials and Methods: Three cohorts including T1D with and without DN (n = 1139) of European descents from the GoKinD study, Swedish T1D with and without ON (n = 303) and Czech control subjects without diabetes, T1D, T2D with and without ON (n = 1418) were enrolled in TaqMan genotyping experiments for IGF2BP2 rs4402960 and IGF2 rs10770125. Igf2bp2 gene expression in kidney tissues of db/db and control mice at the ages of 5 and 26 weeks was examined with real time RT-PCR and Western blot. Results: An association of IGF2BP2 rs4402960 with T2D in the Czech population was replicated. This IGF2BP2 polymorphism (P = 0.037, OR = 0.69 95% CI 0.49-0.98) was found to be associated with DN in male not in female patients with T1D selected from the GoKinD study. In the analyses of combined the GoKinD, Czech and Swedish populations, the association between IGF2BP2 polymorphism and ON in male patients with T1D was still significant (P = 0.030, OR = 0.73, 95% CI 0.54-0.97). IGF2 rs10770125 was also associated with DN in male T1D patients of the GoKinD population (P = 0.038, OR = 0.67 95% CI 0.46-0.98). There might be a genetic interaction between IGF2BP2 and IGF2 (P = 0.05). The Igf2bp2 gene expression levels were increased in the kidneys of db/db mice compared to controls at the age of 5 weeks but not at 26 weeks. Conclusions: The present study has replicated the association of IGF2BP2 rs4402960 with T2D in the Czech population and provided data suggesting that IGF2BP2 may have genetic interaction with IGF2 with a protective effect against DN in male patients with T1D.

- PURPOSE: This study aimed to determine if there are any associations between serum levels of inflammatory markers and proliferative retinopathy (PDR) in type 1 diabetic patients. DESIGN: A cross-sectional design was utilized for this study. METHODS: One hundred twenty-eight type 1 diabetic patients underwent stereo fundus photography according to the Early Treatment Diabetic Retinopathy Study and were divided into two retinopathy groups: no or nonproliferative retinopathy (NDR/NPDR; n=62) and PDR (n=66). Serum levels of tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-1beta, IL-6, soluble vascular cellular adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1 (sICAM-1), P-selectin, and high-sensitivity C-reactive protein (hsCRP) were analyzed. Statistical analysis was performed using nonparametric Mann-Whitney U test and multivariate logistic regression analysis. RESULTS: Patients with PDR had higher levels of TNF-alpha [7.0 pg/ml (<4-17) vs. 6.0 pg/ml (<4-25); P=.009], sVCAM-1 [860 ng/ml (360-2120) vs. 700 ng/ml (310-1820); P<.001], and P-selectin [180 ng/ml (39-400) vs. 150 ng/ml (42-440); P=.017; figures are expressed as median (range)]. There were no differences in serum levels of sICAM-1 or hsCRP. IL-1beta was not detectable in any patient, and IL-6 was detectable in only 22.7% of the patients. In multivariate logistic regression analysis, TNF-alpha was the single, persistent, independent determinant inflammatory marker for PDR. CONCLUSION: The association between TNF-alpha and PDR in type 1 diabetic patients suggests that inflammation might play a role in the pathogenesis of proliferative diabetic retinopathy.

- BACKGROUND: Despite marked improvement in therapy and monitoring of patients with insulin-dependent (type 1) diabetes, diabetic nephropathy remains a serious complication, with subsequent end-stage renal disease in about 20% of cases. OBJECTIVE: To investigate in young patients with type 1 diabetes whether urine α-Glutathione S-transferase to creatinine ratio (α-GST:crea) relates to markers of systemic inflammation and subclinical vasculopathy. DESIGN: Children and adolescents (median age and diabetes duration 14 and 6years, respectively) with type 1 diabetes screened in a previous study for proximal tubular (urine α-GST:crea ratio) and renal (plasma creatinine, cystatin C glomerular filtration rate (GFR), and timed urine albumin excretion rate (AER)) function were, within the same timeframe, also investigated for vascular (blood pressure, carotid artery intima-media thickness (IMT) and compliance (CAC), brachial artery flow-mediated dilatation (FMD) and plasma cyclic guanosine monophosphate (cGMP) and inflammatory (C-reactive protein (CRP), and tumor necrosis factor-alpha (TNF-α)) profiles. Exposure to environmental tobacco smoke (ETS) was assessed through questionnaire (n=67 respondents). RESULTS: None of the patients (n=69) had overt renal insufficiency. AER correlated with age (p=0.01, r=0.3), diabetes duration (p=0.02, r=0.3), FMD (p=0.04, r=-0.3, n=52), CAC (p=0.03, r=-0.3, n=62) and cGMP (p=0.01, r=-0.3, n=59). α-GST:crea was lower (p=0.03) in patients than in controls. α-GST:crea appeared to be particularly lower in older patients (p=0.004, r=-0.34 vs age), in those with worse diabetic control (p=0.03, r=-0.26 vs HbA1c), and in those with lower carotid artery elasticity (p=0.017, r=0.3 vs CAC). Although ETS had no direct significant impact on α-GST:crea, α-GST:crea correlated with FMD only in patients with ETS (r=0.5, p=0.009, n=13). α-GST:crea showed positive association with TNF-α (p=0.01, r=0.3). CONCLUSION: In children and adolescents with type 1 diabetes, lower levels of urine excretion of α-GST:crea appear to be associated with decreasing elasticity and endothelial vasomotor function of peripheral arteries, especially in patients with ETS. In contrast, higher levels of α-GST:crea are more common in patients with elevated markers of systemic inflammation. Large scale prospective studies are needed to clarify the meaning and mechanisms of this association.

- Objective: The aim of this study is to identify risk factors for the loss of measurable plasma C-peptide in newly diagnosed 15- to 35-year-old diabetic subjects. Methods: This Swedish study included 778 subjects. C-peptide levels were obtained each year for 6 years after diagnosis. Loss of measurable C-peptide was defined as a level at or below the lower detection limit of the local assay (0.13 nmol/l). In addition to C-peptide, other baseline covariates included gender, age, body mass index, HLA genotype, and autoantibody levels. Results: Compared with autoantibody-negative subjects, autoantibody-positive subjects had lower median baseline C-peptide (0.27 vs. 0.50, P<001), their levels declined over the study period, and the risk of losing measurable C-peptide was significantly higher when more than one autoantibody was present [odds ratio (OR), 4.0; 95% confidence interval (CI), 2.13-7.54]. Among autoantibody-positive individuals, the presence of GAD65Ab (OR, 1.8; 95% Cl, 1.24-2.51) and islet cell antibodies (OR, 1.6; 95% CI, 1.19-2.18) conferred a higher risk for loss of measurable C-peptide as did female gender (OR, 1.6; 95% CI, 1.17-2.11) and time after diagnosis (OR, 1.5 for each additional year postdiagnosis; 95% CI, 1.41-1.57). Higher baseline C-peptide levels were protective (OR, 0.5 for each additional log nanomoles per liter; 95% CI, 0.36-0.58). Conclusions: This study identified autoantibody status, gender, and baseline C-peptide levels as factors that will be useful for predicting the disease course of 15- to 35-year-old diabetic individuals.

- Aims To assess peripheral neuropathy following a standardized foot examination protocol in a representative population-based cohort of subjects with type 2 diabetes. Methods In a geographically defined population, aged 40–70 years with diabetes prevalence of 3.5% according to medical records, we investigated 156 type 2 diabetic subjects, 95% Caucasian, mean age 61.7±7.2 years, duration of diabetes 7.0±5.7 years, and HbA1c 7.3±2.4% (6.4% Mono-S), by questionnaires, clinical examinations, blood sampling, and review of medical records. Foot examination included clinical signs of peripheral neuropathy and tests of sensibility with monofilament, tuning fork, and assessments of the vibration perception thresholds (VPT). Results Peripheral autonomic neuropathy (PAN) as judged by two or more signs of dysfunction was the most common and affected 43%. The prevalence of peripheral sensory neuropathy (PSN) was 15% by monofilament, 24% by tuning fork, and 28% by VPT expressed as ZscoreVPT ≥2.0 S.D. Twenty-nine percent had a VPT ≥25 V. Signs of peripheral motor neuropathy (PMN) affected 15%. Peripheral neuropathy, at least one variable, affected 67%, whereas 25% were affected by more than one variable of neuropathy, i.e., polyneuropathy. Exclusion of other identified causes for neuropathy than diabetes reduced the prevalence of diabetic polyneuropathy to 23%. Concurrent diabetic complications were 29% for retinopathy, 14% for incipient nephropathy, and 8% for overt nephropathy. The prevalence of macrovascular complications was 62% for CVD, 26% for PVD, and 11% for cerebrovascular lesion (CVL). Conclusion Peripheral neuropathy was common in this representative type 2 diabetes population. Clinical signs of PAN were the most frequent followed by diminished perception of vibration and touch.

- The aim of this study was to compare self-perceived health among diabetic patients who experienced threat of blindness with those who had already gone blind. Another aim was to explore different aspects of self-care in relation to self-perceived health among the subjects. Twenty-one diabetic patients under threat of becoming blind and 23 with diabetes-related blindness agreed to participate in the study. The participants were compared with an age- and gender-matched nondiabetic reference group. Self-perceived health was measured using the 63-item Swedish Health-Related Quality of Life Survey (SWED-QUAL) questionnaire. Data on diabetes-related variables were collected from the patient's hospital records. An interview guide was created for measuring dimensions of self-care. Patients with threat of becoming blind showed better self-perceived health than blind patients, but no differences were found in comparison with the Swedish reference group. Blind patients scored lower in 6 of the 13 health domains and they reported more problems with diabetes self-care than patients with threat of becoming blind. One of the 13 health domains, role limitations due to physical health, seemed to be associated with impaired self-care although only a partial understanding could be demonstrated. The results show that blind patients need specific support to cope well with different self-care situations. A great challenge in future research in diabetes is to implement education programs suitable especially for patients who have gone blind because of diabetes. © 2005 Elsevier Inc. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: This is the first nationwide study with the aim to analyze whether there is an association between country of birth in first-generation immigrants and hospitalization for type 2 diabetes (T2D), and to study whether any such association remains in second-generation immigrants. DESIGN: In this follow-up study, the Swedish Hospital Discharge Register was used to identify all hospital diagnoses of T2D in first- and second-generation immigrants in Sweden between January 1, 1964 and December 31, 2007. Hospitalization rate ratios standardized with regard to gender, age, geographical region, socioeconomic status, obesity, and family history of hospitalization for T2D were estimated in first- and second-generation immigrants. RESULTS: Both increased and decreased risks of hospitalization for T2D were shown for several first-generation immigrant groups. However, only second-generation immigrants with Finnish or former Yugoslavian parents had higher rates of hospitalization for T2D than the reference group. No other differences remained in the second-generation immigrants. CONCLUSIONS: The present study suggests that ethnic environmental factors may be more important than ethnic genetic factors in explaining the observed variation in hospitalization for T2D among first-generation immigrants.

- To investigate the risk of major amputation after elective endovascular therapy in patients with chronic limb threatening ischemia (CLTI) comparing patients with and without diabetes mellitus (DM).In this nationwide cohort study, all patients registered in the Swedish Vascular Register after elective endovascular therapy for CLTI caused by infra-inguinal arterial disease from 2010 to 2014 were included. Among 4578 individuals, 2251 had DM and were registered in the National Diabetes Register between 2009 and 2014. A propensity score adjusted Cox regression analysis was conducted to compare outcomes between groups. Median follow-up was 4.0 and 3.6years for patients with DM and without DM, respectively.The incidence rates of major amputation and acute myocardial infarction (AMI) were 43% (95% CI 1.23-1.67) and 37% (95% CI 1.13-1.67) higher, respectively, among patients with DM compared to patients without DM. There was no difference in mortality (HR 1.04, 95% CI 0.95-1.14).Patients with DM had a higher risk of major amputation and AMI compared to those without DM after elective endovascular therapy for CLTI. Prevention of DM with CLTI is of utmost importance to reduce the risk of adverse limb and cardiovascular outcomes.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: In patients with type 1 diabetes mellitus (T1D), cardiovascular disease (CVD) events are more common and occur earlier in life than in non-diabetics. Reduced brachial artery distensibility (BrachD) is an independent risk factor for development of CVD. Our aim was to determine if adults with T1D have lower BrachD compared to adults without diabetes and also to determine how age and gender affect the relationship of BrachD with T1D status. Materials and methods: BrachD was measured using the Dynapulse instrument in 829 participants (352 with T1D, 477 non-diabetics). An ANCOVA model was used to test the association of BrachD with age, sex, and T1D, and the significance of an age*sex*T1D interaction. Results: Mean BrachD was lower in T1D patients vs. controls (6.43 +/- 1.46 vs. 7.16 +/- 1.48 % change per mmHg, p amp;lt; 0.0001). In a model adjusted for age, T1D, and sex, the interaction of age*T1D*sex was significant (p = 0.0045). Younger women both with and without T1D had higher BrachD than men with and without T1D, but older women with and without T1D had lower BrachD compared to older men with and without T1D. Women with T1D had a steeper decline in BrachD with age than nondiabetic women. Conclusions: BrachD is lower in T1D patients than in non-diabetics, indicating increased vascular stiffness. Younger females have higher BrachD than males, but the decline with age in BrachD is steeper for women, particularly among those with T1D. BrachD may be an inexpensive, non-invasive method to ascertain increased CVD risk in this population. (C) 2016 Elsevier Inc. All rights reserved.

- Aims: Using diabetic foot (OF) as an indicator of severe diabetes, we aimed to investigate the cognitive profile of OF patients and the relations between cognitive functioning and both diabetes complications and comorbidities. Methods: Dementia-free patients with DF aged 30-90 (n = 153) were assessed through medical records and a cognitive battery. Information on diabetes complications and comorbidities was collected via interview; glycated hemoglobin (HbA1c) was tested. Data were analyzed using robust logistic or quantile regression adjusted for potential confounders. Results: The mean Mini-Mental Examination (MMSE) score of patients was 24.6 (SD = 3.6), and 40% had global cognitive dysfunction (MMSE <= 24). Among elderly patients (aged >= 65), MMSE impairment was related to amputation (OR 3.59, 95% CI 1.07-12.11). Episodic memory impairment was associated with foot amputation (OR 4.13, 95% CI 1.11-1528) and microvascular complications (OR 9.68, 95% CI 1.67-56.06). Further, elderly patients with HbA1c <7% had increased odds of psychomotor slowness (OR 7.75, 95% CI 1.55-38.73) and abstract reasoning impairment (OR 4.49, 95% CI: 1.15-17.46). However, such significant associations were not shown in adult patients aged <65. Conclusion: Amputation, microvascular diseases and glycemic control were associated with impaired global cognitive function and its domains among patients aged >= 65.

- PURPOSE: To study prevalence of diabetic retinopathy (DR) at diagnosis (DRAD) and to estimate contributing risk by sociodemographic, cardiovascular and metabolic characteristics present in patients recently diagnosed with type 2 diabetes (T2D) or latent autoimmune diabetes in the adult (LADA).METHODS: Patients (n=2174) recently diagnosed T2D (93%) or LADA (7%) were included upon arrival for their baseline DR screening. Fundus photographs of 4902 eyes were graded by a senior ophthalmologist according to the International Diabetic Retinopathy Disease Severity Scale. Official registers held by Statistics Sweden provided sociodemographic variables. The National Patient Register and Swedish Prescribed Drug Register were used to assess cardiovascular risk. Beta cell function (HOMA2%b) and insulin sensitivity (HOMA2%s) were estimated from fasting (f) C-Peptide using the homeostasis model assessment (HOMA) 2 calculator. Odds ratios (OR) for DRAD were estimated using generalized estimating equation models.RESULTS: The prevalence of DRAD was 12% (7% mild and 5% moderate) and of diabetic macular edema it was 11% (all within vascular arch). The prevalence did not significantly differ between T2D and LADA. Due to sample size, the regression analysis of LADA patients did not yield any significant estimates. In T2D low educational level (≤9years) increased risk for DRAD by 44% (OR 1.44; 95% CI 1.07-1.93) and <50% beta-cell function adjusted for HbA1c and insulin sensitivity at diagnosis increased the risk by 77% (OR 1.77; 95% CI 1.28-2.44). For every unit increase in BMI, risk for DRAD decreased by 3% (OR 0.97; 95% CI 0.95-0.99).CONCLUSIONS: DRAD prevalence in patients recently diagnosed with T2D or is 12%. Low educational level and low beta cell function at diagnosis are risk factors for DRAD. Estimation of beta cell function from (f)C-Peptide and (f)P-Glucose may be a valuable tool in identifying patients at risk for DRAD.

The effect of polymorphisms in the renin-angiotensin-aldosterone system on diabetic nephropathy risk
- 2008

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES:The risk of diabetic nephropathy (DN) can be increased by elevated intraglomerular pressure and glomerular filtration rate, leading to glomerular damage. This can be controlled by the renin-angiotensin-aldosterone (RAA) system, which has an important function regulating both systemic and intrarenal blood pressure. Smoking increases the risk of DN, but not all diabetic patients who smoke develop DN. There is a possibility that smoking has different effects depending on the different genotypes of the individual. We investigated the association of DN with seven polymorphisms in the RAA system and their possible interaction with smoking.SUBJECTS AND METHODS:In the present case-control study, type 1 diabetic patients with diabetes duration > or =20 years, without albuminuria and without antihypertensive treatment (n=197), were included as controls. An albumin excretion rate (AER) of 20-200 microg/min (n=73) was considered as incipient DN, and an AER >200 microg/min was considered as overt DN (n=48). Smoking habits were obtained from questionnaires.RESULTS:Homozygosity for the A allele, of the angiotensin II type 1 receptor (AGTR1) A1166C polymorphism, was associated with increased risk of overt DN (OR=3.04; 99% CI=1.02-9.06), independently of the other associated variables: age, duration of diabetes, ever smoking, HbA1c, and sex. The effect of the AA genotype was enhanced to a four times risk increase among ever-smoking patients. Two alleles of the microsatellite marker adjacent to the angiotensinogen gene were less common among nephropathy cases than among controls, but this was not significant when controlling for the same variables as above.CONCLUSIONS:The risk of having overt DN was increased in patients homozygous for the A1166 allele, and smoking seemed to enhance the effect of the AGTR1 genotype.

- Background and Aims: Although much has been written about the conventional cardiovascular risk factor correlates of the extent of coronary artery calcification (CAC), few studies have been carried out on symptomatic patients. This paper assesses the potential ability of risk factors to associate with an increasing CAC score. Methods: From the European Calcific Coronary Artery Disease (Euro-CCAD) cohort, we retrospectively investigated 6309 symptomatic patients, 62% male, from Denmark, France, Germany, Italy, Spain and the USA. All had conventional cardiovascular risk factor assessment and CI scanning for CAC scoring. Results: Among all patients, male sex (OR = 4.85, p < 0.001) and diabetes (OR = 236, p < 0.001) were the most important risk factors of CAC extent, with age, hypertension, dyslipidemia and smoking also showing a relationship. Among patients with CAC, age, diabetes, hypertension and dyslipidemia were associated with an increasing CAC score in males and females, with diabetes being the strongest dichotomous risk factor (p < 0.001 for both). These results were echoed in quantile regression, where diabetes was consistently the most important correlate with CAC extent in every quantile in both males and females. To a lesser extent, hypertension and dyslipidemia were also associated in the high CAC quantiles and the low CAC quantiles respectively. Conclusion: In addition to age and male sex in the total population, diabetes is the most important correlate of CAC extent in both sexes.

- Aims: To investigate if addition of metformin to standard care (life-style advice) reduces the occurrence of cardiovascular events and death after myocardial infarction (MI) in patients with newly detected prediabetes.Methods: The Myocardial Infarction and new treatment with Metformin study (MIMET) is a large multicentre registry-based randomised clinical trial (R-RCT) within the SWEDEHEART registry platform expected to include 5160 patients with MI and newly detected prediabetes (identified with fasting blood glucose, HbA1c or 2-h glucose on oral glucose tolerance test) at similar to 20 study sites in Sweden. Patients 18-80 years, without known diabetes and naive to glucose lowering therapy, will be randomised 1:1 to open-label metformin therapy plus standard care or standard care alone.Outcomes: Patients will be followed for 2 years for the primary outcome new cardiovascular event (first of death, non-fatal MI, hospitalisation for heart failure or non-fatal stroke). Secondary endpoints include individual components of the primary endpoint, diabetes diagnosis, initiation of any glucose lowering therapy, cancer, and treatment safety. Events will be collected from national healthcare registries.Conclusions: The MIMET study will investigate if metformin is superior to standard care after myocardial infarction in preventing cardiovascular events in patients with prediabetes (Clinicaltrials.gov identifier: NCT05182970; EudraCT No: 2019-001487-30).

- Aims: To compare metabolic control between males and females with type 1 diabetes during adolescence and as young adults, and relate it to microvascular complications. Methods: Data concerning 4000 adolescents with type 1 diabetes registered in the Swedish paediatric diabetes quality registry, and above the age of 18 years in the Swedish National Diabetes Registry was used. Results: When dividing HbA1c values in three groups; < 7.4% (57 mmol/mol), 7.4-93% (57-78 mmol/mol) and >9.3% (78 mmol/mol), there was a higher proportion of females in the highest group during adolescence. In the group with the highest HbA1c values during adolescence and as adults, 51.7% were females, expected value 46.2%; in the group with low HbA1c values in both registries, 34.2% were females, p < 0.001. As adults, more females had retinopathy, p < 0.05. Females had higher mean HbAlc values at diagnosis, 112 vs. 10.9% (99 vs. 96 mmol/mol), p < 0.03, during adolescence, 8.5 vs. 82% (69 vs. 66 mmol/mol) p < 0.01, but not as young adults. Conclusions: Worse glycaemic control was found in adolescent females, and they had a higher frequency of microvascular complications. Improved paediatric diabetes care is of great importance for increasing the likelihood of lower mortality and morbidity later in life.

Tidskriftsartikel (refereegranskat)abstract
- Aims: The neurotransmitter Neuropeptide Y (NPY) was previously reported as a minor autoantigen in newly diagnosed type 1 diabetes (T1D) patients. The single nucleotide polymorphism at rs16139 (T1128C, L7P) in the NPY gene was associated with an increased risk for the development of type 2 diabetes (T2D). We aimed to develop a radiobinding assay for NPY-L (Leucine) and NPY-P (Proline) autoantibodies (A) to study the levels and the association with other islet autoantibodies and neuropathy. Methods: Autoantibodies against NPY-L, NPY-P, ZnT8, GAD65 and IA-2 were studied in T1D (n = 48) and T2D (n = 26) patients with duration up to 42 and 31 years. A subgroup of T1D (n = 32) patients re-examined, 5-8 years after first visit, was tested for peripheral (Z-score) and autonomic neuropathy (E/I ratio). Results: NPY-LA and NPY-PA were detected in 23% and 19% in T1D (p<0.001), and 12% and 23% in T2D patients (p<0.001) compared to 2.5% controls (n = 398). The levels of NPYA declined during follow-up in the T1D patients (p < 0.001). The neuropathy was not related to the NPYA or the other islet autoantibodies. Conclusions: Regardless of the absence of an association between NPYA and neuropathy, NPY may contribute to the pathogenesis of T1D and T2D as a minor autoantigen.

A subgroup of T1D (n=32) patients re-examined, 5-8years after first visit, was tested for peripheral (Z-score) and autonomic neuropathy (E/I ratio). Results: NPY-LA and NPY-PA were detected in 23% and 19% in T1D (p<0.001), and 12% and 23% in T2D patients (p<0.001) compared to 2.5% controls (n=398). The levels of NPYA declined during follow-up in the T1D patients (p<0.001). The neuropathy was not related to the NPYA or the other islet autoantibodies. Conclusions: Regardless of the absence of an association between NPYA and neuropathy, NPY may contribute to the pathogenesis of T1D and T2D as a minor autoantigen.

- Aims: Anemia is common in type 2 diabetes (T2D), particularly in patients with kidney impairment, and often goes unrecognized. Dapagliflozin treatment increases hemoglobin and serum erythropoietin levels. We investigated the effect of dapagliflozin 10-mg/day on hemoglobin in T2D patients with and without anemia. Methods: Data from 5325 patients from 14 placebo-controlled, dapagliflozin-treatment studies of at least 24-weeks duration were pooled. Dapagliflozin's effects (vs. placebo) on hemoglobin, serum albumin, estimated glomerular filtration rate (eGFR), systolic blood pressure, body weight, and safety in patients with and without anemia were evaluated. Results: At baseline, 13% of all T2D patients and 28% of those with chronic kidney disease (eGFR <60 mL/min/1.73 m2) had anemia. Hemoglobin increased continuously to at least week 8 and was sustained throughout 24-weeks follow-up in dapagliflozin-treated patients. Serum albumin increased in dapagliflozin-treated patients at week 4 and remained stable thereafter. Dapagliflozin was well tolerated and corrected anemia in 52% of patients with anemia at baseline (placebo: 26%). Incidences of new-onset anemia were lower in dapagliflozin-treated (2.3%) versus placebo-treated (6.5%) patients. Conclusions: Treatment with dapagliflozin can correct and prevent anemia in T2D patients. A gradual increase in hemoglobin beyond week 4 may indicate an erythropoiesis-stimulating effect of sodium-glucose cotransporter 2 inhibition.

- Aim: SGLT2 inhibitors have been shown to reduce cardiovascular and renal complications in type 2 diabetes (T2D) patients at high cardiovascular risk. Metformin is currently widely used as initial monotherapy in T2D but lacks convincing data to show that it reduces risk of complications. We aim to compare the SGLT2 inhibitor dapagliflozin and metformin as first-line T2D medication with regard to development of complications in a registry-based randomised controlled trial. Methods: The SGLT2 inhibitor or metformin as standard treatment of early stage type 2 diabetes (SMARTEST) trial will enrol 4300 subjects at 30-40 study sites in Sweden who will be randomised 1:1 to either metformin or dapagliflozin. Participants must have T2D duration <4 years, no prior cardiovascular disease, and be either drug-naive or on monotherapy for T2D. Results: The primary endpoint is a composite of all-cause death, major adverse cardiovascular events and occurrence or progression of microvascular complications (retinopathy, nephropathy, diabetic foot lesions). Secondary endpoints include individual components of the primary endpoint, start of insulin therapy, risk factor biomarkers, patient-reported outcome measures, and cost-effectiveness analysis. Outcomes will primarily be assessed using nationwide healthcare registries. Conclusions: The SMARTEST trial will investigate whether dapagliflozin is superior to metformin in preventing complications in early stage T2D.
