OBJECTIVE -To study the healing effect of recombinant human epidermal growth factor (hEGF) on diabetic foot ulcers. RESEARCH DESIGN AND METHODS-A total of 127 consecutive patients were screened and 61 diabetic subjects were recruited into this double-blind randomized controlled study. Predetermined criteria were used for diagnosis and classification of the diabetic wound. The patients were randomized into three groups. All patients attended our Diabetes Ambulatory Care Center every other week for joint consultation with the diabetologist and the podiatrist. Group 1 (control) was treated with Actovegin 5% cream (Actovegin), group 2 with Actovegin plus 0.02% (wt/wt) hEGF, and group 3 with Actovegin plus 0.04% (wt/wt) hEGF. The study end point was the complete closure of the wound. Failure to heal was arbitrarily defined as incomplete healing after 12 weeks.RESULTS -Final data were obtained from 61 patients randomly assigned into three groups. The mean ages of the patients, wound sizes, wound duration, metabolic measurements, and comorbidities were comparable within groups, except that group 3 had more female patients. Mean follow-up for the patients was 24 weeks. Data were cutoff at 12 weeks, and results were analyzed by intention to treat. After 12 weeks, in group 1 (control) eight patients had complete healing, two patients underwent toe amputation, and nine had nonhealing ulcers. In group 2 (0.02% [wt/wt] hEGF) 12 patients experienced wound healing, 2 had toe amputations, and 7 had nonhealing ulcers. Some 20 of 21 patients in group 3 (0.04% [wt/wt] hEGF) showed complete wound healing. Healing rates were 42.10, 57.14, and 95% for the control, 0.02% (wt/wt) hEGF, and 0.04% (wt/wt) hEGF groups, respectively. Kaplan-Meier survival analysis suggested that application of cream with 0.04% (wt/wt) hEGF caused more ulcers to heal by 12 weeks and increased the rate of healing compared with the other treatments (log-rank test, P ϭ 0.0003).CONCLUSIONS -Our data support the contention that application of hEGF-containing cream, in addition to good foot care from a multidisciplinary team, significantly enhances diabetic foot ulcer wound healing and reduces the healing time. Diabetes Care 26:1856 -1861, 2003D iabetic foot ulcer is a major complication of diabetes. People with diabetes show a 5-to 50-fold higher risk of nontraumatic amputation compared with individuals who do not suffer from diabetes (1). Between 1996 and 1998, diabetic patients accounted for 47% of all the lower-limb amputations performed in our hospital (M.W.T., K.-M.L., G.K., unpublished data), comparable to published data (2). The major risk factor leading to diabetic foot ulcer is poor diabetes control, which results in neuropathic and vascular changes. In general, diabetic foot ulcers are difficult to heal and frequently lead to amputation if complicated by infection and gangrene. Several new treatment modalities, such as exposure to an oxygen chamber, the use of platelet-derived growth factor (PDGF), and the application of various local dressings, have p...

It is feasible to integrate treatment into the real life environments of patients with diabetes, and nurse-led transitional care is a practical and cost-effective model. Nurse follow-up is effective in maintaining optimal glycaemic control and enhancing adherence to health behaviours. Management of glycaemic control is better done in the community than in the hospital.

In Caucasians, maturity-onset diabetes of the young (MODY) is mostly caused by mutations in the hepatocyte nuclear factor (HNF)-1a (MODY3) and glucokinase (MODY2) genes. Most Japanese MODY patients, however, are not linked to known MODY genes. In this study, we examined the genetic and clinical characteristics of Chinese subjects with MODY. The study included 146 unrelated families fulfilling the minimum criteria for MODY: two consecutive generations of type II diabetes with at least one member diagnosed under the age of 25. We screened for mutations in the HNF-4a (MODY1), MODY2 and MODY3 genes by direct sequencing. Antibody to glutamic acid decarboxylase (GAD-Ab) was measured in subjects with MODY of unknown cause (MODYX). Insulin resistance index and other clinical data were compared in sex-, age-and duration-matched MODY3 and MODYX patients. In all, 13 families had MODY3 mutations and two had MODY2 mutations. No MODY1 mutation was found. Four of the 12 different MODY3 mutations were newly identified novel mutations (Q243E, A311D, P379R and P488fsdelC). In subjects with MODYX, 3% were GAD-Ab positive and 60% were overweight. Compared to MODY3 patients, MODYX patients had higher body mass index (Po0.02), higher insulin resistance index (P ¼ 0.001) and triglyceride level (Po0.02), lower HDL level (P ¼ 0.001) and more hypertension (Po0.05), but no significant difference in the prevalence of diabetic complications. In conclusion, MODY3 and MODY2 account for only 9 and 1%, respectively, of Chinese MODY. A majority of Chinese MODY patients are due to defects in unknown genes and appear to be characterized by insulin resistance.

Sodium-glucose co-transporter type 2 (SGLT2) inhibitors are a new class of oral anti-diabetic agents with a unique, insulin-independent mode of action. In patients with diabetes who have adequate renal function, SGLT2 inhibitors reduce hyperglycemia by blocking renal glucose reabsorption and increasing urinary glucose excretion. These agents are indicated for the treatment of hyperglycemia in type 2 diabetes mellitus (T2DM), as an adjunct to diet and exercise. In terms of efficacy, they are comparable to most other oral agents, and carry a low risk of hypoglycemia unless combined with sulfonylureas or insulin. They may be used in combination regimens with metformin, sulfonylureas, or insulin. Beyond glucose lowering, SGLT2 inhibitors are associated with modest weight loss and mild anti-hypertensive effects. Emerging cardiovascular and renal outcomes data suggest other potentially beneficial non-glycemic effects, although these findings await confirmation from further studies. The main adverse effects are increased risk of volume depletion and of genitourinary infections, although these can be managed with standard interventions. Rare cases of euglycemic ketoacidosis have been reported in a subset of patients treated with these agents, an issue currently under investigation. SGLT2 inhibitors represent a promising alternative treatment option for T2DM patients in whom the effectiveness of oral anti-hyperglycemic therapy is limited by the risk of hypoglycemia, weight gain, or other adverse effects. Safety and efficacy (up to 4 years) have been demonstrated in a range of T2DM patient populations, although more studies will be needed to determine whether treatment with SGLT2 inhibitors improves patient-important outcomes in the longer term.

Various data have demonstrated inadequate glycemic control amongst Asians with type 2 diabetes mellitus (T2DM), possibly on account of suboptimal titration of basal insulin—an issue which needs to be further examined. Here we review the available global and Asia-specific data on titration of basal insulin, with a focus on the use of insulin glargine 100 U/mL (Gla-100). We also discuss clinical evidence on the efficacy and safety of titrating Gla-100, different approaches to titration, including some of the latest technological advancements, and guidance on the titration of basal insulin from international and local Asian guidelines. The authors also provide their recommendations for the initiation and titration of basal insulin for Asian populations. Discussion of the data included in this review and in relation to the authors’ clinical experience with treating T2DM in Asian patients is also included. Briefly, clinical studies demonstrate the achievement of adequate glycemic control in adults with T2DM through titration of Gla-100. However, studies investigating approaches to titration, specifically in Asian populations, are lacking and need to be conducted. Given that the management of insulin therapy is a multidisciplinary team effort involving endocrinologists, primary care physicians, nurse educators, and patients, greater resources and education targeted at these groups are needed regarding the optimal titration of basal insulin. Technological advancements in the form of mobile or web-based applications for automated dose adjustment can aid different stakeholders in optimizing the dose of basal insulin, enabling a larger number of patients in Asia to reach their target glycemic goals with improved outcomes.Electronic supplementary materialThe online version of this article (doi:10.1007/s13300-017-0322-z) contains supplementary material, which is available to authorized users.
