Improved glycemic control is associated with a reduced risk of diabetic complications. Optimal management of patients with type 2 diabetes includes nutritional therapy, physical activity, and pharmacotherapy for glycemic control. Most patients with type 2 diabetes are initially managed with oral antidiabetic agents, but as β-cell function declines and the disease progresses, insulin therapy is frequently needed to maintain glycemic control. Insulin therapy given with multidose insulin injection regimen or by continuous insulin infusion is needed for patients with type 1 diabetes to achieve control. Obesity and its associated insulin resistance contribute to greater insulin requirements in patients with both type 1 and type 2 diabetes to achieve glycemic control, creating a need for concentrated insulin. Concentrated insulin formulations can be prescribed as an alternative to 100 unit/mL insulin and provide the advantage of low injection volume, leading to less pain and possibly fewer insulin injections. This review includes a stepwise analysis of all currently available concentrated insulin products, analyzes the most up-to-date evidence, and presents this in combination with expert guidance and commentary in an effort to provide clinicians with a thorough overview of the characteristics and benefits of concentrated insulins in patients with type 1 and type 2 diabetes–instilling confidence when recommending, prescribing, and adjusting these medications.

Normal Glucose

The pathophysiology of diabetes as a disease is characterised by an inability to maintain normal glucose homeostasis. In type 1 diabetes, this is due to autoimmune destruction of the pancreatic β-cells and subsequent lack of insulin production, and in type 2 diabetes it is due to a combination of both insulin resistance and an inability of the β-cells to compensate adequately with increased insulin release. Animal models, in particular genetically modified mice, are increasingly being used to elucidate the mechanisms underlying both type 1 and type 2 diabetes, and as such the ability to study glucose homeostasisin vivohas become an essential tool. Several techniques exist for measuring different aspects of glucose tolerance and each of these methods has distinct advantages and disadvantages. Thus the appropriate methodology may vary from study to study depending on the desired end-points, the animal model, and other practical considerations. This review outlines the most commonly used techniques for assessing glucose tolerance in rodents and details the factors that should be taken into account in their use. Representative scenarios illustrating some of the practical considerations of designingin vivoexperiments for the measurement of glucose homeostasis are also discussed.

Introduction: The association between the incidence of glutamic acid decarboxylase antibodies(GADAs) and risk of diabetes in pregnant women is controversial. Here, our aim was to investigate the incidence and clinical relevance of GADA and its association with development of post-delivery diabetes in women with gestational diabetes mellitus (GDM).Methods: This cohort study was conducted in Torbat–e Heydarieh (Khorasan Razavi, Iran) from October 2015 to March 2017. A total of 147 pregnant women with GDM were included in case group. The control group consisted of 147 healthy controls. A GAD diagnostic kit (Diametra Co.,Italy) was used for diagnosis of GADA. The history of insulin therapy and the development of diabetes one year after delivery were investigated.Results: Of 147 pregnant women with GDM, 9 (6.1%) had GADA in their sera. 14.3% (21 out of 147) of women with GDM had history of insulin therapy. 33.3% (7 of 21) of women who had received insulin developed diabetes one year after delivery. Type 1 and type 2 diabetes were observed in, respectively, 1 (0.7%) and 7 (4.8%) of women with GDM at one year after delivery.At one year after delivery, no women in GADA negative women was diagnosed with type 1 diabetes. However, type 2 diabetes was observed in 2.9% of GADA negative pregnant women.Type 1 and type 2 diabetes were also noticed in, respectively, 11.1% and 33.3% of GADA positive mothers at one year after delivery.Conclusion: The prevalence of GADA was 6.1% in diabetic pregnant women. The GADA positivity and history of insulin therapy during pregnancy were significant risk factors for diabetes at one year after delivery. In addition, development of type 1 diabetes was higher in GADA positive pregnant women with GDM than GADA negative women.
