The Complexity of Vascular and Non-Vascular Complications of Diabetes: The Hong Kong Diabetes Registry

Diabetes is a complex disease characterized by chronic hyperglycemia and multiple phenotypes. In 1995, we used a doctor-nurse-clerk team and structured protocol to establish the Hong Kong Diabetes Registry in a quality improvement program. By 2009, we had accrued 2616 clinical events in 9588 Chinese type 2 diabetic patients with a follow-up duration of 6 years. The detailed phenotypes at enrollment and follow-up medications have allowed us to develop a series of risk equations to predict multiple endpoints with high sensitivity and specificity. In this prospective database, we were able to validate findings from clinical trials in real practice, confirm close links between cardiovascular and renal disease, and demonstrate the emerging importance of cancer as a leading cause of death. In addition to serving as a tool for risk stratification and quality assurance, ongoing data analysis of the registry also reveals secular changes in disease patterns and identifies unmet needs

An update on the management of nephropathy in type 2 diabetes

Background. To provide an update on the latest evidence-based management of nephropathy in type 2 diabetes. Methods. A literature search (MEDLINE 1966 to 2002) was performed using the key words “diabetic nephropathy,” and relevant book chapters were also reviewed, to identify well-controlled, prospective landmark studies and expert review articles on diabetic nephropathy (DN). Data and conclusions from the selected articles that provided solid evidence regarding the optimal management of DN were extracted and interpreted in light of clinical and research experience with Chinese patients. Results. DN is the leading cause of end-stage renal disease worldwide. High blood pressure, dyslipidemia, long duration of diabetes, poor glycemic control and central obesity are important risk factors. Microalbuminuria is a practical marker to predict the development of overt nephropathy in type 2 diabetic patients. Risk factor modification, renal function monitoring and combined therapies are the current integrated approaches to manage patients with diabetic kidney disease. Optimal glycemic control is a fundamental goal, but effective antihypertensive and possibly lipid-lowering therapy delay the progression of DN. Recent large clinical trials support the earlier experimental data that angiotensin-converting enzyme inhibitors and angiotensin receptor blockers have important renoprotective actions independent of their blood pressure lowering actions. Conclusions. Screening for microalbuminuria and monitoring renal function will identify patients with DN at an early stage and allow for intervention. Tight glycemic control and aggressive antihypertensive treatment as well as the use of renin-angiotensin system inhibitors should substantially delay the progression of nephropathy

Cost-effectiveness analysis of high-dose omeprazole infusion as adjuvant therapy to endoscopic treatment of bleeding peptic ulcer

Background: Intravenous administration of proton pump inhibitors after endoscopic treatment of bleeding peptic ulcers has been shown to decrease the rate of recurrent bleeding and the need for subsequent surgery. Yet there is a relative lack of formal assessment of this practice. The aim of this study was to examine the cost-effectiveness of this therapy by using standard pharmacoeconomic methods. Methods: The present study was performed in conjunction with a randomized controlled clinical trial that included 232 patients who received either omeprazole (80 mg intravenous bolus followed by infusion at 8 mg/hour for 72 hours) or placebo after hemostasis was achieved endoscopically. A cost-effectiveness analysis was performed to evaluate the different outcomes of the trial. All related direct medical costs were identified from patient records. Cost-effectiveness ratios were calculated. Results: Analysis by the Kolmogorov-Smirnov test showed that the direct medical cost in the omeprazole group was lower than that for the placebo group. Cost-effectiveness ratios for omeprazole and placebo groups were, respectively, HK$28,764 (US$ 3688) and HK$36,992 (US$ 4743) in averting one episode of recurrent bleeding in one patient after initial hemostasis was achieved endoscopically. Conclusions: Intravenous administration of high-dose omeprazole appears to be a cost-effective therapy in reducing the recurrence of bleeding and need for surgery in patients with active bleeding ulcer after initial hemostasis is obtained endoscopically.link_to_subscribed_fulltex
