The Diabcare-Asia 1998 study--outcomes on control and complications in type 1 and type 2 diabetic patients.

UNLABELLED: The aim of this study was to describe the glycaemic and metabolic control and diabetes-related complications in type 1 and type 2 Asian patients. METHODS: Data of diabetes patients from 230 diabetes centres in 12 Asian regions were collected on a retrospective-prospective basis through review of medical records, interview and laboratory assessments. Analysis of glycated haemoglobin (HbA1c) was carried out in central laboratories appointed by Bio-Rad. The data collection case record forms were scanned electronically. RESULTS: 22177 patients with valid data made up the analysis population. Among patents with type 1 and type 2 diabetes, there was a higher proportion of women than men (53% vs. 47% for type 1 patients and 56% vs. 44% for type 2 diabetes). Hypertension (61%) and overweight (40% with BMI > or = 25 kg/m2 were common in type 2 patients. Dyslipidaemia was also present in at least half of both types of patients. Control of glycaemia (mean HbA,1c and fasting blood glucose [FBG]) was poor in type 1 (9.9 +/- 2.5%; 10.2 +/- 5.2 mmol/l) and type 2 patients (8.5 +/- 2.0%; 8.9 +/- 3.4 mmol/l). Glycaemia in the majority of both types of patients fell short of those stipulated by various guidelines. In type 2 patients, glycaemia deteriorated (HbA1c > 7.5%, FBG > or = 7.0 mmol/l) with duration of diabetes > 7 years. Both types of diabetes appear to share a similar high prevalence of complications of cataract, retinopathy and neuropathy, although the prevalence of cataract (27%) and neuropathy (35%) was higher in type 2 diabetes. Screening for microalbuminuria was not common. CONCLUSIONS: The Inadequate metabolic and hypertension control, especially in type 2 patients, needs to be addressed.

Epidemiology of diabetes mellitus in Western pacific region: focus on Philippines.

The aim of Diabcare-Asia project was to collect data on diabetes control, management and complication status among patients in 12 Asian countries. Information was extracted from medical records, interviews and laboratory assessment. The majority (96%) of patients were diagnosed with type 2 diabetes mellitus, with mean age (+/-SD) of 59.3+/-12.5 years and mean diabetes duration of 9.4+/-7.0 years. Mean body mass index (BMI) was 24.7+/-4.9 kg/m(2) and the majority (60%) had BMI < or =25 kg/m(2). The majority (70%) of patients were treated with oral antidiabetic drugs (OADs), 15% with insulin, 10% with insulin and OAD combination therapy and 5% with diet control. Among OADs-treated patients, most (44%) received two or more medication. Majority of patients (> or =79%) had satisfactory metabolic control of triglycerides (<2.2 mmol/l), total cholesterol (<6.5 mmol/l) and HDL cholesterol (>0.9 mmol/l). Glucose self-monitoring (either urine or blood) was only practiced by 50% of patients. Glycaemic control (HbA1c) was unsatisfactory as majority of patients had HbA1c>7.4% (73%) and 50% had fasting blood glucose (FBG)>7.8 mmol/l. Cataract (26%), neuropathy (42%) and cerebral stroke (6%) were the most frequently reported complications. Clearly, the level of glycaemic control in majority of patients is below satisfaction. Effective education must be emphasised in the management of diabetes.
