  • Goal is to link healthcare and research (including “-omics”) data for each individual in the existing cohorts and configure the data for federated analysis with NUHS

We were awarded NMRC Centre Grant (CG) to comprehensively develop our clinical research capability to meet the growing challenge of Common and Complex Chronic Conditions (4Cs).

The quantum of CG awarded is $1.5 millions for 4 years. It consists of 3 main cores i.e. Facility Core, Research Personnel Core, and Administrative Core.

Facility Core: The core will provide equipment and consumables necessary for maintaining the biobanking activities. A portion of this core will be used to facilitate federated data repository through collaboration with the National University Health System (NUHS).

Research Personnel Core: The core will provide manpower support for biobanking of human specimens and conducting epidemiological studies. A portion of this core will be supporting manpower in NUHS for data repository.

Administrative Core: The core will provide an oversight of biobanking and research data from ethical, operational and managerial perspectives. Our current staff employed by CG include:

DORIS

DORIS (Diabetic Kidney Disease – Onset and Progression Risk Factors Cohort)

  • Successor of the long-running Diabetic Nephropathy cohort, which has produced more than 20 publications
  • Aims to better understand the determinants of the onset and progression of Diabetic Kidney Disease in the Singapore population

DORIS is the abbreviation for “Diabetic Kidney Disease – Onset and Progression Risk Factors Cohort”, the latest upcoming cohort study by Clinical Research Unit. It is the successor of our long-running Diabetic Nephropathy cohort, which has produced more than 20 publications to date. In the next-phase, our aim is to recruit approximately 1920 multi-ethnic patients with Type 2 Diabetes (T2DM) to better understand the determinants of onset and progression of Diabetic Kidney Disease (DKD) in the Singapore population.

DKD is the leading cause of end stage renal disease in Singapore, and an established risk factor for cardiovascular disease and mortality in people with diabetes. Recent data suggest that while major complication related to diabetes (e.g. cardiovascular disease) is declining, the incidence of DKD remains unabated. Through our DORIS cohort, we hope to better understand the range of factors that drive DKD.

Therefore, continue to watch this space for more updates on the DORIS cohort!

SMART2D

Smart2D (Study of Macro-angiopathy and Micro-vascular Reactivity in Type 2 Diabetes)

  • Launched in 2011 to study the impact of diabetes in blood vessel function and common diabetes-related complications
  • Part of a nation-wide, multi-institution consortium to study diabetic kidney disease and retinopathy
  • With the award of S$1.5 million in 2019 from the National Medical Research Council (NMRC), SMART2D has been granted a total of nearly S$5 million in funding (FY2012 to FY2021).
  • In this third phase of the study, all 1,800 past participants are recalled, to monitor the progression of their disease over three years, until 2022.
  • Emphasis on lifestyle factors; in addition to bio specimens and follow-up data on diabetic complications, data is collected on diet, physical activity and frailty
  • Published 33 papers in peer-reviewed scientific journals and shared at numerous national and international conferences
  • Findings on association of early-onset diabetes with cognitive impairment awarded best oral presentation at 13th International Congress of the Asian Society Against Dementia and 6th Singapore International Neuro-Cognitive Symposium
  • Abstracts selected as competition finalists for Singapore Health Biomedical Congress (SHBC) 2019

The Singapore Study of Macro-angiopathy and Micro-vascular Reactivity in Type 2 Diabetes (SMART2D) is funded by the highly competitive National Medical Research Council’s Program Project Grant (PPG) and Clinician Scientist Individual Research Grant (CS-IRG). The SMART2D study was launched in FY2011 to study the impact of diabetes on blood vessel function and commonly encountered diabetes-related complications among Singaporeans. Funded by a SGD 2-million PPG, Drs Lim Su Chi, Tavintharan Subramaniam, Yeoh Lee Ying and Sum Chee Fang led the study and recruited 2,057 Type 2 Diabetic patients with and without vascular complications.

Upon the completion of the PPG (which is a cross-sectional study) in FY2013, our institution was further awarded a SGD 1.5-million CS-IRG in FY2014 to conduct a follow-up prospective study aimed at recalling all of the initial participants for re-evaluation and to collect new data to study disease progression in relation to changes in risk factors. By exploiting the synergy between clinical and genetic epidemiology, SMART2D will continue as a longitudinal study that investigates the relationship between risk factors (genetic and non-genetic), vascular function (i.e. intermediate phenotype - endothelial reactivity and arterial stiffness) and final phenotypes (diabetic foot syndrome, nephropathy, retinopathy, cognitive dysfunction and mood disorders).

The SMART2D study involves collaboration with prestigious institutions such as the Genome Institute of Singapore (GIS), National University of Singapore (NUS), National Healthcare Group Polyclinics (NHGP) and the Wellcome Trust Centre for Human Genetics at Oxford, UK. In addition, the cohort is part of a nation-wide, multi-institution consortium (DYNAMO: Diabetes study in Nephropathy And other Microvascular complications) devoted to studying diabetic kidney disease and retinopathy. Observations from SMART2D have also been published in several renowned peer-reviewed journals and presented at conferences worldwide and the finding that central obesity is associated with young onset diabetes and increased susceptibility to diabetes-related complications such as chronic kidney disease (CKD) has been reported in Singapore’s national newspaper and in the Singapore Medical Journal. We are currently recruiting volunteers to participate in our follow-up prospective study. Various health assessment tests, including blood and urine tests, foot screening, calculation of body composition and cognitive tests may be conducted. The results obtained from these tests can be used to inform the volunteers (and their doctors) of any changes in their health status and blood vessel functions. If you are interested in learning more about the study or would like to join us as a study volunteer, please contact Dr Keven Ang (Project Manager) at 6602-2343 or Ms Amy Ou (Project Lead-Research Nurse) at 8128-9442.

MODY Registry Study

What is MODY?

  • A type of diabetes caused by a single gene abnormality, often misdiagnosed as the common Type 1 or Type 2 diabetes
  • Registry set up to identify individuals with MODY and provide a genetic diagnosis so that they can receive the best treatment

MODY stands for Maturity-Onset Diabetes of the Young. It is a type of diabetes that is caused by a single gene abnormality (mutation) and is also known as monogenic diabetes. MODY can often be misdiagnosed as the common Type 1 or Type 2 diabetes as they share similar features. Determining the gene mutation in MODY is important to confirm the diagnosis.

Mutation in more than 20 genes have been shown to cause MODY. The most common ones include HNF4A, GCK and HNF1A (MODY-1,-2 and -3) as well as KCNJ11 and ABCC8 (can cause diabetes as young as 1 year old or less, i.e. neonatal diabetes). These genes directly affect the ability of the insulin-producing cells in the pancreas to sense, produce and release insulin, which is required to control sugar levels in our body.

The KTPH-NHG MODY Registry is set up as part of our research study to identify individuals with MODY and to provide a genetic diagnosis for this group of individuals. A genetic diagnosis of MODY may aid doctors in providing the best treatment for these individuals (e.g. switching from insulin to tablets).

News Feature
Patient with rare diabetes tracked with new registry (The Sunday Times, 15/10/2017).

Related Publication
A preliminary study to evaluate the strategy of combining clinical criteria and next generation sequencing (NGS) for the identification of monogenic diabetes among multi-ethnic Asians.

MODY Registry

Targeting primarily the population-catchment of NHG-Yishun campus, the KTPH-NHG MODY registry is set up with the following primary aims:

  • To identify individuals with MODY and to perform genetic testing for these group of individuals.
  • To facilitate optimization of treatment by their care-provider for individuals with confirmed genetic diagnoses (e.g. switching from insulin to oral anti-diabetic medications like sulphonylureas).
  • To provide MODY-related counselling to affected individuals and their family members.
  • To provide a platform for gathering longitudinal information to better understand and treat monogenic diabetes.

Your participation will help us understand the genetic basis of monogenic diabetes, and also answer questions such as the number of people who are affected in our local population, the type of treatment that is best for each different genetic type, and other medical problems that might arise due to the presence of such gene mutations. These information will help doctors understand the genetic basis of the disease and offer suitable treatment to the patients.

Do I have MODY?

You may have MODY if you have any of the following features:

  • Diabetes diagnosed when you were less than 35 years old. We strongly recommend people with diabetes-onset below 1 year old to receive genetic testing.
  • Type 2 Diabetes (T2D) but not overweight
  • Longstanding T2D that is well controlled with diet alone
  • Strong family history of diabetes (more than 2 generations)

Familial Hypercholesterolemia

What is Familial Hypercholesterolemia (FH) ?

Aims to raise awareness of this genetic condition that puts one at risk for early heart disease, its diagnosis and treatment options

Based on global statistics, Familial Hypercholesterolemia (FH) affects approximately 20,000 patients in Singapore but more than 90% are unaware of this condition and remain undiagnosed! Early diagnosis can allow affected individuals and theirfamily members to start treatment early and ultimately reduce the risk of getting early heart attack.

  • FH leads to early heart disease, the #1 killer in the world.
  • Men with FH have 50% risk of having heart disease by age of 50.
  • Women with FH have 30% risk of having heart disease by age of 60.

Diagnosis & Treatment

You may have FH if you have any of the following symptoms/signs

  • High blood cholesterol
    Total Cholesterol > 7.5mmol/l or 290mg/dl
    LDL Cholesterol > 4.9mmol/l or 189mg/dl
  • Family history of
    • High cholesterol
    • or Early heart attack
    • or Cholesterol deposits around eyes or under skin
  • Positive Mutation

Where can I check my cholesterol levels?

You can get your cholesterol levels checked at any public or private clinic. If you suspect you may have one of the above conditions, discuss with your doctor.

Family screening & early treatment

If you have high cholesterol and test positive for mutation, higher dosage of medication may be required. Lifestyle changes such as healthy diet, exercise and medication can help to reduce the risk of heart attack. Early diagnosis and treatment are available. Take action now and seek medical advice.

If you do a mutation test and discover the mutations, your doctor will share the findings with you and advise your immediate family members to come for testing. Patients with FH mutation have a 50% chance of passing it to their children. Early detection will allow you and your affected family members to start medication early and reduce the risk of premature heart attack.

Awareness Activties

In collaboration with Singapore Heart Foundation, the FHCARE team from KTPH has set up a booth on National Heart Week/World Heart Day 2018 on 29 September 2018 to help raise FH awareness to the public. This event is celebrated annually by Singapore Heart Foundation (SHF) provides a platform to motivate fellow Singaporeans to lead a positive and active lifestyle.

Diabetic Nephropathy (DN)

Diabetic Nephropathy (DN)

The Diabetic Nephropathy (DN) cohort at Khoo Teck Puat Hospital (KTPH) (Alexandra Health Pte Ltd) has been initiated since 2002. It includes ~ 5,499 multi-ethnic patients with type 2 diabetes (age 58.3 ± 11.7 years old, duration of diabetes 12.0 ± 8.7 years, Chinese 67.5%, Malays 19.1%, Asian Indians 13.3% and others 0.2%). Blood and urine samples collected at baseline visit have been cryo-preserved. In collaboration with local and overseas institutions, we aim to study biomarkers (both genetic and non-genetic) associated with the development and progression of DN in multi-ethnic Asians with diabetes.

The cohort is enriched by subjects with renal impairment in accordance with the aim of the study (MDRD eGFR 67.8 ± 37.7 ml/min/1.73m2, CKD stage 1- 28.1%, stage 2-31.3%, stage 3-20.8%, stage 4- 9.0% and stage 5-10.7%). Approximately 30.0% of the subjects are classified as having microalbuminuria (urinary albumin-to-creatinine ratio, .i.e. ACR 30 to 299 mg/g) and 27.7% of them are classified as having macroalbuminuria (ACR >= 300 mg/g). The longitudinal trajectory of eGFR and ACR has also been recorded in a large proportion of the subjects.

The median follow-up duration of this cohort is 5.7 years. Incident diabetes related outcomes can be ascertained by linkage of cohort database with Singapore National Disease registries (Renal Registry, Myocardial Infarct Registry, Death/birth Registry, Stroke Registry and Cancer Registry).

OMICS Study

OMICS (Obesity – Metabolism & Intervention Cohort Study)

Multi-disciplinary research in fields such as epidemiology, genetics, metabolomics, lifestyle and nutrition to gain insights into functional changes related to obesity among multi-ethnic Asians in Singapore

Obesity is a complex multifaceted disease arising from interactions of biological, behavioural and environmental factors, and contributes to many comorbid conditions e.g. Type 2 diabetes (T2DM). Bariatric Surgery (also known as Gastrointestinal Surgery, or Bariatric and Metabolic Surgery) is highly effective in inducing weight loss among morbidly obese individuals thereby ameliorating adverse metabolic consequences.

The OMICS project is co-initiated by Dr Anton Cheng (Deputy Director of Weight Management Programme at our Health For Life Centre) and Dr Lim Su Chi (Clinical Director, Clinical Research Unit) to provide resources for conducting multi-disciplinary research in fields such as epidemiology, genetics, metabolomics, lifestyle and nutrition to elucidate obesity pathophysiology among multi-ethnic Asians in Singapore.

Constituting the core of OMICS is a prospective-cohort founded since 2007. To date, it has ~400 severely obese (mean BMI~40 kg/m2) individuals who underwent bariatric surgery. About one-third of them has T2DM, whom we have performed pre- and post-bariatric surgery multiple time-point OGTT. Additionally, we have established a rich bio-repository of bio-banked blood and urine samples, cryopreserved human primary adipocytes (both subcutaneous and visceral), skeletal myocytes and longitudinal clinical data collected from the research participants.

The goals of the OMICS project are:

  1. To understand the best practice for candidate-selection to derive benefit from bariatric surgery
  2. To unveil the mechanisms elicited by bariatric surgery so as to facilitate the development of powerful non-invasive interventions for improving obesity and/or T2DM
  3. To identify biomarkers to better risk-stratify obesity/T2DM patients i.e. personalized medicine
