Diabetic microangiopathic complications in young Chinese diabetic patients: a clinic-based cross-sectional study.

Microangiopathic complications are major causes of morbidity and mortality in diabetic patients. We studied 150 consecutive young Chinese diabetic subjects attending the Prince of Wales Hospital Diabetes Center on their presence of diabetic microangiopathic complications and the relationships with other risk factors. All patients with aged younger than 40 years and had an age of onset of disease at younger than 35 years. Their known duration of diabetes was 57.2 +/- 5.0 months. Of these 150 patients, 50 (33.3%) had microangiopathic complications, 34 (22.7%) had albuminuria, 11 (7. 3%) had peripheral neuropathy, and 21 (14%) had retinopathy. Using multiple logistic regression analysis, albuminuria was independently associated with body-mass index and systolic blood pressure, peripheral neuropathy was associated with fasting plasma glucose and lower high-density lipoprotein cholesterol, and retinopathy was associated with duration of disease and fasting plasma glucose. In conclusion, there were high percentages of microangiopathic complications, particularly albuminuria, in our young Chinese diabetic patients. Obesity, high blood pressure, and poor glycemic control are important for these complications.

Helicobacter pylori infection in Chinese subjects with type 2 diabetes.

The relationship between diabetes and Helicobacter pylori (HP) infection is controversial. In this study, we examined the possible relationship between HP infection and type 2 diabetes in Chinese subjects. Sixty-three Chinese type 2 diabetic patients (mean age +/- SD: 49.9 +/- 12.0 years; range: 17-76 years) were recruited irrespective of the duration of diabetes or type of therapy. Twenty-nine (46%) of them had upper gastrointestinal symptoms and the other 34 (54%) did not. Another 55 age- and sex-matched non-diabetic subjects (mean age +/- SD: 45.6 +/- 15.6 years, p=0.098; range 18-79 years) with dyspepsia indicated for upper endoscopy were recruited as a comparison group. Upper endoscopy was performed with antral mucosal biopsy specimens taken for rapid urease test (CLO test). HP infection was considered to be present if the rapid urease test was positive. The rates of HP infection of the diabetic and non-diabetic individuals were 50.8% and 56.4% respectively (p: NS). The rate of HP infection was similar between the 2 groups of diabetic patients with or without gastrointestinal symptoms (42.9% vs. 56.3%, p: NS). Using logistic regression analysis (forward stepwise) with age, sex, glycaemic control, duration of diabetes and upper gastrointestinal symptoms as independent variables to predict the risk of HP infection in diabetic patients, none of the parameters enter into the model. In conclusion, the rate of HP infection in Hong Kong Chinese subjects with type 2 diabetes is around 50%, which is similar to control subjects. No association was found between HP infection, glycaemic status, and duration of diabetes and upper gastrointestinal symptoms in these diabetic subjects.

TSH secreting pituitary adenoma: a rare cause of thyrotoxicosis.

Thyroid-stimulating hormone (TSH) secreting pituitary adenoma is a rare but important cause of thyrotoxicosis. It poses a challenge for both diagnosis and management. We report the case of a young Chinese man presenting with thyrotoxicosis, complicated by congestive heart failure, secondary to a TSH secreting pituitary adenoma. The case illustrates the importance of prompt diagnosis and allows discussion of both medical and surgical management, including the use of a long-acting somatostatin analogue.
