Eric’s expanding waistline

• review the features of type 2 diabetes mellitus; • outline common changes in the vasculature associated with diabetes; • summarize renal, ocular and neuronal complications of poorly controlled diabetes; • explain the uses of biguanide, sulfonylurea and thiazolidinedione drugs in the management of type 2 diabetes. His workmates had started to tease Eric about his expanding waistline; the overalls he wore to work would no longer fasten round his middle. In fact, Eric was only too aware that his weight had increased by about 40 lb in the last three years to 200 lb, mostly as a result of daily takeaways and drinking copious amounts of beer each night … Continue reading

Sulfonylurea Antidiabetics

Synonyms: Antidiabéticos sulfonilureas; Sulfonylurea Antidiabetics; Sulphonylurea Antidiabetics Adverse Effects Gastrointestinal disturbances such as nausea, vomiting, heartburn, anorexia, diarrhoea, and a metallic taste may occur with sulfonylureas and are usually mild and dose-dependent increased appetite and weight gain may occur. Skin rashes and pruritus may occur and photosensitivity has been reported. Rashes are usually hyper sensitivity reactions and may progress to more serious disorders (see below). Facial flushing may develop in patients receiving sulfonylureas, particularly chlorpropamide, when alcohol is consumed (see under Interactions, below). Mild hypoglycaemia may occur severe hypoglycaemia is usually an indication of overdosage and is relatively uncommon. Hypoglycaemia is more likely with long-acting sulfonylureas such as … Continue reading

Pregnancy: Management of labour

Dramatic changes in insulin sensitivity may occur in insulin-dependent diabetics at the time of delivery. Once active labour has started, insulin requirements fall. After delivery, once the placenta and its hormonal products have been removed, there is a further rapid reduction in insulin requirement. Indeed, immediately after delivery, insulin requirements may fall below pre-pregnancy values. During labour the simplest scheme is to use a constant infusion of 10% glucose at a rate of 1 L every 8 hours. An independent insulin infusion of human soluble insulin, initially at 1 unit/h, is also given; this is subsequently adjusted on the basis of hourly bedside blood glucose. This system may be used irrespective … Continue reading

Pregnancy: Oral hypoglycaemic agents

Commonly, women with type 2 diabetes are taking sulphonylureas and/or metformin prior to conception. Hitherto, these have little place in the management of diabetes in pregnancy, although the use of metformin has been attracting increasing interest in recent years. The main anxiety about sulphonylureas in pregnancy is the possibility of further increasing the degree of fetal hyperinsulinaemia by direct drug-induced stimulation. Sulphonylureas, with the exception of glyburide, cross the placenta and have been implicated as a direct cause of neonatal hypoglycaemia. The long-acting agent chlorpropamide is particularly dangerous and should not be used in the last 4 weeks of gestation. There is no convincing evidence that these drugs are teratogenic. Metformin, … Continue reading

Type 2 diabetes: the management of blood glucose. Part 3

The National Institute for Clinical Excellence (NICE) [UK] Which drugs should be used initially to control blood glucose? Metformin When blood glucose is inadequately controlled with lifestyle interventions, metformin is the first-line drug of choice in all patients with type 2 diabetes, particularly those who are overweight (BMI >25 kg/m) (see Figure: Treatment algorithm for management of blood glucose in type 2 diabetes). Sulphonylureas are an alternative in patients who are not overweight. However, metformin is the only oral … Continue reading
