Background: The aim of the web-based Joint Asia Diabetes Evaluation (JADE) program is to establish a registry for quality assurance, monitoring, and evaluation. Methods: The JADE electronic portal provides templates for data collection, supplemented by risk stratification, care protocols, and decision support. Herein, data from 3687 patients with Type 2 diabetes, enrolled over 15months in 2007-2009 from seven Asian countries, are reported. Results: Of the patients, 46.1% were men, the median (range) age was 58 (15-93years), and median disease duration was 6.5 (0-71) years; 16.2% had at least one cardiovascular-renal complication (10.0% coronary heart disease, 3.3% stroke, 3.1% peripheral vascular disease, 0.4% end-stage renal disease), 20.4% had diabetic retinopathy, 15.0% had sensory neuropathy, 7.5% had chronic kidney disease, and 20.7% of men had erectile dysfunction. Hypertension, dyslipidemia, and central obesity affected 84.6%, 76.8%, and 53.5% of patients, respectively. Treatment targets were HbA1c <7% in 35.3%, blood pressure <130/80mmHg in 32.3%, and low-density lipoprotein-cholesterol <2.6mmol/L in 34.0%. The rate of attaining one, two, and three targets was 38.7%, 23.4%, and 5.4%, respectively. Using the JADE Risk Engine, 60% of patients with clinical complications and 20% of those with multiple risk parameters were predicted to have a major event within 5years. Older age, short disease duration, adherence to diet, control of other risk factors, and not smoking were independently associated with HbA1c <7% (all P<0.05). Conclusions: It is possible to use a web-based protocol to establish a registry for risk stratification and facilitate early intervention. © 2011 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Blackwell Publishing Asia Pty Ltd.

Obesity Reviews | Year: 2012
Obesity is a major health hazard and despite lifestyle modification, many patients frequently regain any lost body weight. The use of western anti-obesity drugs has been limited by side effects including mood changes, suicidal thoughts, and gastrointestinal or cardiovascular complications. The effectiveness and safety of traditional Chinese medicine including Chinese herbal medicine (CHM) and acupuncture provide an alternative established therapy for this medical challenge. In this systematic review, we used standard methodologies to search, review, analyse and synthesize published data on the efficacy, safety and relapse of weight regain associated with use of CHM and acupuncture. We also examined the rationale, mechanisms and potential utility of these therapies. A total of 12 electronic databases, including Chinese, English, Korean and Japanese, were searched up to 28 February 2010. Randomized controlled trials (RCTs) forCHMand/or acupuncture with comparative controls were considered. We used the Jadad scale to assess methodological qualities, the random effect model in the pooled analysis of therapeutic efficacy to adjust for heterogeneity and funnel plots to explore publication bias. After screening 2,545 potential articles from the electronic databases, we identified 96 RCTs; comprising of 49 trials on CHM treatment, 44 trials on acupuncture treatment and 3 trials on combined therapy for appraisal. There were 4,861 subjects in the treatment groups and 3,821 in the control groups, with treatment duration ranging from 2 weeks to 4 months. Of the 77 publications written in Chinese, 75 had a Jadad score <3, while 16 of the 19 English publications had a Jadad score of >3. Efficacy was defined as body weight reduction ≥2 kg or body mass index (BMI) reduction ≥0.5 kg/m2. Compared with placebo or lifestyle modification, CHM and acupuncture exhibited respective 'risk ratio' (RR) of 1.84 (95% CI: 1.37-2.46) and 2.14 (95% CI: 1.58-2.90) in favour of body weight reduction, with a mean difference in body weight reduction of 4.03 kg (95% CI: 2.22-5.85) and 2.76 kg (95% CI: 1.61-3.83) and a mean difference in BMI reduction of 1.32 kg m-2 (95% CI: 0.78-1.85) and 2.02 kg m-2(95% CI: 0.94-3.10), respectively. Compared with the pharmacological treatments of sibutramine, fenfluramine or orlistat, CHM and acupuncture exhibited an RR of 1.11 (95% CI: 0.96-1.28) and 1.14 (95% CI: 1.03-1.25) in body weight reduction, mean difference in body weight reduction of 0.08 kg (95% CI: -0.58 to 0.74) and 0.65 kg (95% CI: -0.61 to 1.91), and mean difference in BMI reduction of 0.18 kg m-2 (95% CI: -0.39 to 0.75) and 0.83 kg m-2 (95% CI: 0.29-1.37), respectively. There were fewer reports of adverse effects and relapses of weight regain in CHM intervention studies conducted in China than studies conducted outside China. CHM and acupuncture were more effective than placebo or lifestyle modification in reducing body weight. They had a similar efficacy as the Western anti-obesity drugs but with fewer reported adverse effects. However, these conclusions were limited by small sample size and low quality of methodologies. © 2012 The Authors. Source

Background: In patients with type 2 diabetes, chronic kidney disease (CKD) is associated with increased risk of hypoglycaemia and death. Yet, it remains uncertain whether hypoglycaemia-associated mortality is modified by CKD.Methods: Type 2 diabetic patients, with or without CKD at enrolment were observed between 1995 and 2007, and followed up till 2009 at hospital medical clinics. We used additive interaction, estimated by relative excess risk due to interaction (RERI) and attributable proportion due to interaction (AP) to examine possible synergistic effects between CKD and severe hypoglycaemia (defined as hospitalisations due to hypoglycaemia in the 12 months prior to enrolment) on the risk of death.Results: In this cohort of 8,767 type 2 diabetic patients [median age: 58 (interquartile range: 48 to 68) years; disease duration: 5 (1 to 11) years, men: 47.0%], 1,070 (12.2%) had died during a median follow-up period of 6.66 years (3.42-10.36) with 60,379 person-years.Upon enrolment, 209 patients had severe hypoglycaemia and 194 developed severe hypoglycaemia during follow-up (15 patients had both). In multivariable analysis and using patients without severe hypoglycaemia nor CKD as the referent group (683 deaths in 7,598 patients), severe hypoglycaemia alone (61 deaths in 272 patients) or CKD alone (267 death in 781 patients) were associated with increased risk of death [Hazard ratio, HR: 1.81(95%CI: 1.38 to 2.37) and 1.63 (1.38 to 1.93) respectively]. Having both risk factors (59 deaths in 116 patients) greatly enhanced the HR of death to 3.91 (2.93 to 5.21) with significant interaction (RERI: 1.46 and AP: 0.37, both p-values < 0.05).Conclusions: Severe hypoglycaemia and CKD interact to increase risk of death in type 2 diabetes patients. © 2014 Kong et al.; licensee BioMed Central Ltd.

There are gaps between recommendations on regular screening for diabetic kidney disease (DKD) and clinical practice especially in busy and low resource settings. SUDOSCAN (Impeto Medical, Paris, France) is a non-invasive technology for assessing sudomotor function using reverse iontophoresis and chronoamperometry which detects abnormal sweat gland function. Vasculopathy and neuropathy share common risk factors and we hypothesized that SUDOSCAN may be used to detect chronic kidney disease (CKD). Between 2012 and 2013, SUDOSCAN was performed in a consecutive cohort of 2833 Hong Kong Chinese adults with type 2 diabetes. Chronic kidney disease was defined as estimated glomerular filtration rate <60 ml/min/1.73m2. In this cross-sectional cohort (mean age 58.6±9.5 years, 55.7% male, median disease duration 8 [interquartile range 3-14] years), 5.8% had CKD. At a cut-off SUDOSCAN-DKD score of 53, the test had sensitivity of 76.7%, specificity of 63.4% and positive likelihood ratio of 2.1 to detect CKD. The area under receiver operating characteristic curve for CKD was 0.75 (95% confidence interval 0.72-0.79). Patients without CKD but low score had worse risk factors and complications than those with high score. We conclude that SUDOSCAN may be used to detect patients at risk of impaired renal function as part of a screening program in Chinese population, especially in outreach or low resource settings. © 2015 Luk et al.

Background: The prevalence of diabetes is increasing in young adults in Asia, but little is known about metabolic control or the burden of associated complications in this population. We assessed the prevalence of young-onset versus late-onset type 2 diabetes, and associated risk factors and complication burdens, in the Joint Asia Diabetes Evaluation (JADE) cohort. Methods: JADE is an ongoing prospective cohort study. We enrolled adults with type 2 diabetes from 245 outpatient clinics in nine Asian countries or regions. We classified patients as having young-onset diabetes if they were diagnosed before the age of 40 years, and as having late-onset diabetes if they were diagnosed at 40 years or older. Data for participants' first JADE assessment was extracted for cross-sectional analysis. We compared clinical characteristics, metabolic risk factors, and the prevalence of complications between participants with young-onset diabetes and late-onset diabetes. Findings: Between Nov 1, 2007, and Dec 21, 2012, we enrolled 41 029 patients (15 341 from Hong Kong, 9107 from India, 7712 from Philippines, 5646 from China, 1751 from South Korea, 705 from Vietnam, 385 from Singapore, 275 from Thailand, 107 from Taiwan). 7481 patients (18%) had young-onset diabetes, with age at diagnosis of mean 32·9 years [SD 5·7] versus 53·9 years [9·0] with late-onset diabetes (n=33 548). Those with young-onset diabetes had longer disease duration (median 10 years [IQR 3-18]) than those with late-onset diabetes (5 years [2-11]). Fewer patients with young-onset diabetes achieved HbA1c concentrations lower than 7% compared to those with late-onset diabetes (27% vs 42%; p<0·0001) Patients with young-onset diabetes had higher mean concentrations of HbA1c (mean 8·32% [SD 2·03] vs 7·69% [1·82]; p<0·0001), LDL cholesterol (2·78 mmol/L [0·96] vs 2·74 [0·93]; p=0·009), and a higher prevalence of retinopathy (1363 [20%] vs 5714 (18%); p=0·011) than those with late-onset diabetes, but were less likely to receive statins (2347 [31%] vs 12 441 [37%]; p<0·0001) and renin-angiotensin-system inhibitors (1868 [25%] vs 9665 [29%]; p=0·006). Interpretation: In clinic-based settings across Asia, one in five adult patients had young-onset diabetes. Compared with patients with late-onset diabetes, metabolic control in those with young-onset diabetes was poor, and fewer received organ-protective drugs. Given the risk conferred by long-term suboptimum metabolic control, our findings suggest an impending epidemic of young-onset diabetic complications.
