- Background Differentiation between Type 1 and Type 2 diabetes in adults is difficult at diagnosis. In this study we tested the hypothesis that autoantibodies at diagnosis are predictive for insulin treatment within 3 years in patients initially not classified as Type 1 diabetes. Methods In a nationwide population-based study, blood samples were obtained from 764 patients, all diagnosed with diabetes during a 2-year period. At diagnosis, 583 (76%) were classified as Type 1, 110 (14%) as Type 2 and 71 (9.3%) could not be classified. Results Among patients not classified as Type 1 diabetes, 52 (47%) of Type 2 and 42 (59%) of unclassified patients were positive for islet cell antibodies CICA), glutamic acid decarboxylase antibodies (GADA) or tyrosine phosphatase antibodies (IA-2A). These patients (n=94) had lower body mass index (BMI) (p<0.001) and lower C-peptide (p<0.001) compared to the autoantibody negative patients (n=87). Compared to clinically classified Type 1 diabetes patients positive for autoantibodies (n=477), they have higher BMI (p<0.001), higher C-peptide (p<0.001) and the same levels of ICA, GADA and IA-2A. After 3 years, 93% of autoantibody positive patients initially not classified as Type 1 were on insulin. When ICA, GADA, IA-2A, BMI and C-peptide were tested in a multiple logistic regression, only GADA was signiificant for insulin treatment within 3 years (OR = 18.8; 95% CI 1.8-191) in patients treated with diet or oral drugs at diagnosis. Conclusions A correct classification is difficult in adult diabetic patients. The presence of pancreatic autoantibodies, especially GADA, at diagnosis of diabetes are highly predictive for insulin therapy within 3 years from diagnosis.

- Background The aim of the study is to assess the relationship between the shape of plasma glucose concentration during the OGTT and future risk for T2DM. Methods 2445 non-diabetic subjects from the Botnia study received an OGTT at baseline and after 7-8 years of follow-up. Results NGT and IFG subjects who returned their plasma glucose concentration following an ingested glucose load below FPG within 60 min had increased insulin sensitivity, greater insulin secretion and lower risk for future T2DM compared to NGT and IFG subjects whose post-load plasma glucose concentration required 120 min or longer to return their plasma glucose level to FPG level. IGT subjects who had a lower plasma glucose concentration at 1-h compared to 2-h during oGrr had greater insulin sensitivity, better beta cell function and lower risk for future T2DM. Conclusions These data suggest that the shape of glucose curve can be utilized to assess future risk for T2DM. Copyright (C) 2010 John Wiley & Sons, Ltd.

- Type 2 diabetes is the most common metabolic disorder today and has reached epidemic proportions in many countries. Insulin resistance and inflammation play a central role in the pathogenesis of type 2 diabetes and are present long before the onset of the disease. During this time, many of the complications associated with type 2 diabetes are initiated. Of major concern is the two- to fourfold increase in cardiovascular morbidity and mortality in this group compared to a nondiabetic population. Obesity, characterized by enlarged fat cells, and insulin resistance are, like type 2 diabetes, associated with impaired adipogenesis and a low-grade chronic inflammation that to a large extent emanates from the adipose tissue. Both these processes contribute to unfavourable alterations of the circulating levels of several bioactive molecules (adipokines) that are secreted from the adipose tissue, many of which have documented inhibitory effects on insulin sensitivity in the liver and peripheral tissues and, in addition, have negative effects on the cardiovascular system.Here we review current knowledge of the adipose tissue as an endocrine organ, the local and systemic effects of a chronic state of low-grade inflammation residing in the adipose tissue, and, in particular, the effects of inflammation and circulating adipokines on the vascular wall.

- The future for diabetes is grave. Now described as the global epidemic of the 21st century, the increasing incidence of diabetes (in 2007 over 246 million people affected by diabetes) will place considerable strain on resources and will bring suffering to many if the preventative measures promoted by the International Diabetes Federation (IDF), the International Working Group on the Diabetic Foot (IWGDF) and other diabetes representative organizations are not put into effect. Ulcers of the foot in diabetes are a source of major suffering and cost. Investing in a diabetic foot care guideline can be one of the most cost-effective forms of healthcare expenditure, provided the guideline is goal-focused and properly implemented. The objective of the IWGDF, founded in 1996, is to develop guidelines that will reduce the impact of diabetic foot disease through cost-effective and quality healthcare, based on the principles of evidence-based medicine. Three IWGDF working groups were invited to write specific consensus guidelines on different subjects, according to the current standards of evidence based medicine. Therefore, for the first time, new 2007 texts were produced according to a systematic review of the literature, in order to inform protocols for routine care and to highlight areas which should be considered for further study. After reaching worldwide consensus, the review reports and specific guidelines were launched in May 2007.

- The diabetic foot constitutes a tremendous challenge for patients, caregivers and the health care system. The International Consensus Document of 1999 was a milestone in the recognition of the importance and consequences of the diabetic foot. Since then, many original papers have been published in this area.Large cohort studies have given us a deeper understanding regarding factors related to the outcome of diabetic foot ulcers: according to these studies, the severity of diabetic foot ulcers is greater than previously reported. More than 50% of individuals' foot ulcers have signs of infection at admission, and one-third have signs of both peripheral artery disease (PAD) and infection. The co-morbidities increase significantly with increasing severity of the foot disease. However, the trend in all these studies is a successive improvement in healing rate (50-60% at 20 weeks follow-up, > 75% at 1 year). It is important to differentiate between neuropathic and neuro-ischaemic ulcers with regard to factors related to outcome and co-morbidities.Recent research has emphasized the importance of psychological factors in the development and outcome of diabetic foot ulcers. Studies have shown that perceptions of the individual's own risks based on symptoms, and their own beliefs in the efficacy of self-care, can affect foot-care practice.The importance and influence of the health care organization and reimbursement should not be underestimated, both in the prevention and management of diabetic foot lesions. The diabetic foot should be considered a lifelong condition, as having had one ulcer dramatically increases the risk of developing a new ulcer.In an individual with diabetes and a foot ulcer, the ulcer should be considered as a sign of multi-organ disease, and a holistic approach to both management and prevention is recommended.

- Background We have previously shown that two injections of 20 mu g alum-formulated glutamic acid decarboxylase 65 (GAD(65)) (GAD-alum; Diamyd (R)) in children with recent-onset type 1 diabetes lead to preservation of residual insulin secretion. In vitro cytokine production at the 15 months follow-up indicated immunomodulation. In the present study, we took advantage of peripheral blood mononuclear cells, cryopreserved during early follow-ups, to investigate whether the immunomodulatory effect of GAD-alum was apparent earlier after treatment, preceding the changes previously reported at 15 months.Methods Peripheral blood mononuclear cells from 70 type 1 diabetic children, randomly assigned GAD-alum (n = 35) or placebo (n = 35), that had been frozen at baseline (n = 27) and after 1 (n = 58), 3 (n = 67) and 9 (n = 66) months, were stimulated in vitro with GAD(65), tyrosine phosphatase-like protein IA-2 peptide, insulin peptide, GAD-alum, alum formulation or phytohaemagglutinin. Interleukin (IL)-5, -6, -10, -12, -13, -17, tumour necrosis factor and interferon-gamma were measured in cell supernatants and serum samples using Luminex. Expression of FOXP3 and transforming growth factor-beta was determined by real-time reverse transcription polymerase chain reaction.Results Already 1 month after the first injection, GAD(65)-induced IL-5 and IL-13 together with FOXP3 were enhanced in GAD-alum-treated patients compared to those with placebo. The in vitro response at 3 and 9 months was characterized by a broader range of cytokines in the treated group. Notably, only the T-helper 2-associated cytokines IL-5 and IL-13 together with FOXP3 increased continuously over time.Conclusions Treatment with GAD-alum in type 1 diabetic children induced an early T-helper 2 immune enhanced response to GAD(65), followed by a wider spectrum of cytokines at 3 and 9 months.

- Background: Middle Eastern immigrants to Europe represent a high risk population for type 2 diabetes. We compared prevalence of novel subgroups and assessed risk of diabetic macro- and microvascular complications between diabetes patients of Middle Eastern and European origin. Methods: This study included newly diagnosed diabetes patients born in Sweden (N = 10641) or Iraq (N = 286), previously included in the All New Diabetes in Scania cohort. The study was conducted between January 2008 and August 2016. Patients were followed to April 2017. Incidence rates in diabetic macro- and microvascular complications were assessed using cox-regression adjusting for the confounding effect of age at onset, sex, anthropometrics, glomerular filtration rate (eGFR) and HbA1c. Findings: In Iraqi immigrants versus native Swedes, severe insulin-deficient diabetes was almost twice as common (27.9 vs. 16.2% p < 0.001) but severe insulin-resistant diabetes was less prevalent. Patients born in Iraq had higher risk of coronary events (hazard ratio [HR] 1.84, 95% CI 1.06–3.12) but considerably lower risk of chronic kidney disease (CKD) than Swedes (HR 0.19; 0.05–0.76). The lower risk in Iraqi immigrants was partially attributed to better eGFR. Genetic risk scores (GRS) showed more genetic variants associated with poor insulin secretion but lower risk of insulin resistance in the Iraqi than native Swedish group. Interpretation: People with diabetes, born in the Middle East present with a more insulin-deficient phenotype and genotype than native Swedes. They have a higher risk of coronary events but lower risk of CKD. Ethnic differences should be considered in the preventive work towards diabetes and its complications.
