Background: Of 463 million people with diabetes worldwide, over 50% reside in Asia. Sulphonylureas (SUs) such as gliclazide are essential medications listed by the World Health Organization with clinical use for over 60 years. Aim: We explored clinical profiles and patterns of oral glucose lowering drug (OGLD) use in Asian patients with type 2 diabetes (T2D), with a focus on SUs including gliclazide. Method: Patients with T2D aged ≥18 years from 11 countries/regions (China, Hong Kong, India, Indonesia, Korea, Malaysia, Philippines, Taiwan, Thailand, Vietnam, and Singapore) with structured assessment and prospectively enrolled in the Joint Asia Diabetes Evaluation (JADE) Register between November 2007 and December 2019 were included. Patients with type 1 diabetes or treated with insulin/injectable glucagon-like peptide-1 receptor agonists were excluded. Results: Amongst 62,512 patients (mean ± SD age: 57.3 ± 11.8 years; 46.4% women), 54,783 (87.6%) were treated with OGLD at enrolment. Most patients received one (37.5%) or two (44.2%) OGLDs. Metformin was used by 84.1% of treated patients, followed by SUs (59.4%) and DPP-4 inhibitors (23.0%). SUs were used alone (9.0%) or in combination (50.4%), mainly with metformin (30.6%) and metformin plus DPP-4 inhibitors (9.2%). Amongst SU users, gliclazide (47.0%) was most commonly prescribed, followed by glimepiride (40.3%) and glibenclamide (8.4%). Amongst SU users, gliclazide users were more likely than gliclazide non-users to achieve HbA1c < 7% (OR 1.09, 95% CI 1.02–1.17) with lower risk of self-reported hypoglycaemia (OR 0.81, 95% CI 0.72–0.92), when adjusting for sociodemographic factors, cardiometabolic risk factors, medication use, country/region and year of registration.Tabled 1Treated with any OGLD (N=54,783)Treated with any SUs (N=32,558)Treated with gliclazide (N=15,312)Age(years)mean ± SD57.5±11.658.0±11.559.7±11.5Menn (%)29,473 (53.8%)17,349 (53.3%)7,900 (51.6%)BMI(kg/m2)mean ± SD26.2±4.526.1±4.425.8±4.3BMI≥25 kg/m2n (%)29,921 (56.8%)17,668 (56.1%)7,728 (52.1%)Diabetes duration (years)mean ± SD5 (2-10)6 (3-12)7 (3-12)≤1 year (%)n (%)11,902 (21.9%)4,965 (15.4%)2,421 (16.0%)eGFR (mL/min/1.73m2)mean ± SD81.9±22.180.2±22.579.7±22.1<60 mL/min/1.73m2n (%)7,529 (16.5%)5,155 (18.8%)2,684 (19.8%)Hypertensionn (%)46,587 (85.6%)28,147 (87.0%)13,042 (85.6%)Dyslipidaemian (%)41,447 (83.1%)24,647 (82.7%)11,731 (81.8%)Diabetes complicationsn (%) Chronic kidney disease7,592 (13.9%)5,189 (15.9%)2,707 (17.7%) Diabetic retinopathy5,890 (11.8%)3,952 (13.4%)2,385 (17.1%) Peripheral sensory neuropathy5,263 (9.7%)3,555 (11.0%)1,214 (8.0%) Coronary heart disease4,845 (8.8%)2,988 (9.2%)1,575 (10.3%)Class of OGLDn (%) Metformin46,080 (84.1%)25,888 (79.5%)11,981 (78.2%) Sulphonylureas32,558 (59.4%)-- DPP-4 inhibitors12,591 (23.0%)7,189 (22.1%)2,631 (17.2%) Thiazolidinedione4,776 (8.7%)2,884 (8.9%)733 (4.8%) Alpha-glucosidase inhibitors3,509 (6.4%)2,217 (6.8%)684 (4.5%) Glinides748 (1.4%)72 (0.2%)25 (0.2%) SGLT2 inhibitors284 (0.5%)153 (0.5%)104 (0.7%) Open table in a new tab Discussion: This large register-based study provides unique insights into clinical characteristics and patterns of OGLD use in Asian patients with T2D confirming the popular use of SUs, often combined with metformin. Affordability, good glycaemic control and safety profiles support the use of SUs including gliclazide as a first line OGLD in patients with T2D.
