Optimal fasting plasma glucose level for diagnosis of diabetes in a Singaporean population

Khoo Joan

Aim: Diabetes mellitus is defined by the World Health Organization (WHO) as fasting plasma glucose (FPG) ≥7.0 mmol/l (mM) or 2-hour post-load glucose (2HPG) ≥11.1 mM in the 75-gram oral glucose tolerance test (OGTT). However, reported FPG cut-off levels that correspond to this 2HPG level are below 7.0 mM in Asian studies. Our study thus aims to find the optimal FPG cut-off that corresponds to 2HPG of 11.1 mM in an Asian population in Singapore.<p class="abstext...

An unusual case of Cushing’s syndrome secondary to ACTH producing prostate adenocarcinoma

Zeng Wanling , Khoo Joan

Introduction: Cushing’s syndrome (CS) secondary to ectopic adrenocorticotrophic hormone (ACTH)–producing prostate cancer is rare with less than 30 cases reported. We report a case of Cushing’s syndrome secondary to prostate adenocarcinoma with recurrent hypokalemia, sepsis and rapid disease progression. A 61-year-old man presented in January 2019 with 3-week history of lower limb swelling and weakness. Past medical history is significant for metastatic prosta...

Are we missing patients with primary aldosteronism (PA) if we require both elevated aldosterone: renin ratio (ARR) and elevated aldosterone levels?

Puar Troy , Khoo Joan , Zhang Meifen

Introduction: Although the Endocrine Society guidelines recommend using aldosterone: renin ratio (ARR) to screen patients for primary aldosteronism (PA), whether to include a cut-off for aldosterone levels remains controversial. In Singapore, most centres require both an ARR >550 (ng/dl)/(ng/ml per h) and aldosterone ≥15 ng/dl. However, it has been shown that patients with PA may have aldosterone levels<15 ng/dl, and also respond well to mineralocorticoid antagon...

Assessing the new Primary Aldosteronism guidelines recommendation to omit confirmatory testing in selected patients – severity of hypokalaemia may be included

Tan Sarah , Zhang Meifen , Khoo Joan , Puar Troy

Background: Patients with an elevated aldosterone renin ratio (ARR) should proceed for a confirmatory test to diagnose primary aldosteronism (PA) before undergoing further investigations such as CT imaging and adrenal venous sampling. The recent 2016 clinical guidelines have included a new recommendation: that in the setting of spontaneous hypokalaemia, undetectable plasma renin, and plasma aldosterone concentration (PAC) >20 ng/dl, patients may not require further confirm...

Comparing effects of weight loss by liraglutide with intensive lifestyle modification on hepatic steatosis, inflammation and stiffness, and insulin resistance in obese Asians with non-alcoholic fatty liver disease (NAFLD)

Khoo Joan , Law Ngai-Moh , Hsiang John , Tan Jessica , Ang Tiing-Leong

Background and Aims: Non-alcoholic fatty liver disease (NAFLD), a leading cause of cirrhosis and liver cancer, is increasing worldwide due to rising obesity rates, particularly in Asia. Weight loss induced with diet and exercise decreases hepatic steatosis and inflammation, but requires greater efforts to sustain compared to medication. We therefore aimed to compare the effects of liraglutide, a glucagon-like peptide-1 agonist which induces weight loss, on hepatic steatosis an...

Weight loss through lifestyle modification or liraglutide is associated with improvement of NAFLD severity and changes in amino acid concentrations

Khoo Joan , Koo Seok-Hwee , Ching Jianhong , Soon Gaik-Hong , Kovalik Jean-Paul

Introduction: Non-alcoholic fatty liver disease (NAFLD), defined as excess fat accumulation in the liver, is increasingly prevalent due to obesity. NAFLD may lead to steatohepatitis and eventually cirrhosis. Weight loss, either through diet and exercise or medications such as the glucagon-like peptide-1 agonist liraglutide, improves transaminitis, a marker of NAFLD severity. Visceral obesity is associated with increased plasma levels of the amino acids alanine, phenylalanine, ...
