INTRODUCTION: Though insulin has no upper limit in dosage, we do not encounter very high dose requirements too often. The reported case is the first in Bangladesh to require more than 1000 international units (IU) of subcutaneous insulin per day. CASE PRESENTATION: A 44-year old male diabetic patient from Bangladesh presented with unusually uncontrolled diabetes mellitus due to extreme insulin resistance. Despite dramatic increase in insulin step by step up to 1110 IU of concomitant short and intermediate acting insulin per day by subcutaneous route, his blood glucose remained over 12 mmol/L persistently, in all the fasting, pre-prandial, postprandial and random samples...

The incidence of type 2 diabetes mellitus (T2DM) among children and adolescents has been rising. This condition is associated with obesity, and it's prevalence is higher among minority or female youth. Lifestyle modification including diet and exercise is only successful in a small proportion of patients; therefore, pharmacotherapy approaches are needed to treat T2DM among youth. Currently, in the USA, only metformin and insulin are approved for the treatment of T2DM in children. However, several antihyperglycemic agents including exenatide, glimepiride, glyburide, liraglutide, pioglitazone, and rosiglitazone are also used off-label in this population...

Type 2 diabetes is a chronic disease affecting a large portion of the world population and is treated by orally administered drugs. Since these drugs are often taken in high doses and are excreted unchanged or partially metabolised many of them are nowadays detected in surface waters or wastewater treatment plants effluents. Unmetabolised antidiabetics or some of their transformation products retain their pharmacological activity, therefore their presence in the environment is highly undesired. One of the main routes of elimination from wastewaters or surface waters is biodegradation...

PURPOSE: The management of hyperglycemia is challenging in older patients with type 2 diabetes owing to excess fragility and risk for adverse outcomes should hypoglycemia episodes occur. We evaluated baseline β-cell function as a potential risk factor for the development of hypoglycemia when saxagliptin or glimepiride was added in patients aged ≥65 years whose type 2 diabetes was poorly controlled on stable metformin monotherapy. METHODS: A post hoc analysis of data from the GENERATION (Efficacy and Tolerability of Saxagliptin Compared with Glimepiride in Elderly Patients with Type 2 Diabetes: A Randomized, Controlled Study) trial, which enrolled 720 patients aged ≥65 years, was conducted...
