A cross-sectional study to assess beta-cell function in individuals with recently diagnosed young-onset type 2 diabetes mellitus and its’ complications / Journal of the ASEAN Federation of Endocrine Societies

Objective@#The primary objective was to assess beta-cell function of recently-diagnosed young-onset type 2 diabetes mellitus (T2DM) individuals using basal and stimulated C-peptide levels. The secondary objective was to examine the association between C-peptide with metabolic factors and diabetes complications.@*Methodology@#A cross-sectional study was conducted for young-onset T2DM individuals aged 18-35 years with a disease duration of not more than 5 years. Plasma C-peptide was measured before and after intravenous glucagon injection. Demographic data, medical history and complications were obtained from medical records and clinical assessment. Continuous data were expressed as median and interquartile range (IQR). Categorical variables were described as frequency or percentage. Multivariable linear regression analysis was used to determine factors associated with C-peptide levels.@*Results@#113 participants with young-onset T2DM with a median (IQR) age of 29.0 (9.5) years and 24 (36) months were included in this study. The median (IQR) basal and stimulated C-peptide was 619 (655) pmol/L and 1231 (1024) pmol/L. Adequate beta-cell function was present in 78-86% of the participants based on the basal and stimulated C-peptide levels. We found hypertension, obesity and diabetic kidney disease (DKD) to be independently associated with higher C–peptide levels. In contrast, females, smokers, those on insulin therapy and with longer duration of disease had lower C–peptide levels.@*Conclusion@#Most recently diagnosed young-onset T2DM have adequate beta-cell function. Elevated C-peptide levels associated with obesity, hypertension and diabetic kidney disease suggest insulin resistance as the key driving factor for complications.

Fenofibrate for the prevention of progression of non-proliferative diabetic retinopathy: review, consensus recommendations and guidance for clinical practice.

The prevalence of diabetic retinopathy (DR), and associated morbidity is high in the Asia-Pacific region. Emerging evidence suggests a potential role for fenofibrate in the prevention of progression of DR, especially in patients with cardiovascular risk, and pre-existing mild-to-moderate DR. Fenofibrate has also been found to reduce maculopathy, and the need for laser treatment in these patients. Considering these benefits of fenofibrate, a group of experts from the fields of endocrinology and ophthalmology convened in May 2017, to discuss on the the mechanism of action, and clinical efficacy of fenofibrate in DR. The findings from key clinical studies on fenofibrate in DR were reviewed by the experts, and consensus statements were derived to define the role of fenofibrate in the prevention and treatment of DR. The statements were rated based on the GRADE criteria. An algorithm was also developed for the screening and treatment of DR in patients with type 2 diabetes (T2D), and the place of fenofibrate was defined in the algorithm. The expert recommendations, and the algorithm provided in this review will serve as a guide to the clinicians to reconsider the adjunctive use of fenofibrate for preventing the progression of DR in selected T2D patients.

Management of prediabetes in Malaysian population: An experts’ opinion

@#Introduction: Prediabetes, typically defined as blood glucose levels above normal but below diabetes thresholds, denotes a risk state that confers a high chance of developing diabetes. Asians, particularly the Southeast Asian population, may have a higher genetic predisposition to diabetes and increased exposure to environmental and social risk factors. Malaysia alone was home to 3.4 million people with diabetes in 2017; the figure is estimated to reach 6.1 million by 2045. Developing strategies for early interventions to treat prediabetes and preventing the development of overt diabetes and subsequent cardiovascular and microvascular complications are therefore important. Methods: An expert panel comprising regional experts was convened in Kuala Lumpur, for a one-day meeting, to develop a document on prediabetes management in Malaysia. The expert panel comprised renowned subject-matter experts and specialists in diabetes and endocrinology, primary-care physicians, as well as academicians with relevant expertise. Results: Fifteen key clinical statements were proposed. The expert panel reached agreements on several important issues related to the management of prediabetes providing recommendations on the screening, diagnosis, lifestyle and pharmacological management of prediabetes. The expert panel also proposed changes in forthcoming clinical practice guidelines and suggested that the government should advocate early screening, detection, and intensive management of prediabetes. Conclusion: This document provides a comprehensive approach to the management of prediabetes in Malaysia in their daily activities and offer help in improving government policies and the decision-making process.

Weathering the crisis: A case of Thyroid crisis with Propranolol-Induced Circulatory Collapse successfully treated with Therapeutic Plasma Exchange / Journal of the ASEAN Federation of Endocrine Societies

@#Thyroid crisis is a life-threatening form of thyrotoxicosis characterized by multi-system dysfunction. Therapeutic plasma exchange has been reported to be effective in removing excessive circulating thyroid hormones. We present a 46-year-old female with recently diagnosed Graves’ disease associated with thyrotoxic cardiomyopathy admitted for thyroid crisis complicated by propranolol-induced circulatory collapse, acute kidney injury and ischemic hepatitis. The tachyarrhythmia was refractory to conventional therapy. Initiation of TPE resulted in rapid clinical and biochemical stabilization.

Right ventricular dysfunction and pulmonary hypertension: a neglected presentation of thyrotoxicosis.

Thyrotoxicosis is associated with cardiac dysfunction; more commonly, left ventricular dysfunction. However, in recent years, there have been more cases reported on right ventricular dysfunction, often associated with pulmonary hypertension in patients with thyrotoxicosis. Three cases of thyrotoxicosis associated with right ventricular dysfunction were presented. A total of 25 other cases of thyrotoxicosis associated with right ventricular dysfunction published from 1994 to 2017 were reviewed along with the present 3 cases. The mean age was 45 years. Most (82%) of the cases were newly diagnosed thyrotoxicosis. There was a preponderance of female gender (71%) and Graves' disease (86%) as the underlying aetiology. Common presenting features included dyspnoea, fatigue and ankle oedema. Atrial fibrillation was reported in 50% of the cases. The echocardiography for almost all cases revealed dilated right atrial and or ventricular chambers with elevated pulmonary artery pressure. The abnormal echocardiographic parameters were resolved in most cases after rendering the patients euthyroid. Right ventricular dysfunction and pulmonary hypertension are not well-recognized complications of thyrotoxicosis. They are life-threatening conditions that can be reversed with early recognition and treatment of thyrotoxicosis. Signs and symptoms of right ventricular dysfunction should be sought in all patients with newly diagnosed thyrotoxicosis, and prompt restoration of euthyroidism is warranted in affected patients before the development of overt right heart failure. LEARNING POINTS: Thyrotoxicosis is associated with right ventricular dysfunction and pulmonary hypertension apart from left ventricular dysfunction described in typical thyrotoxic cardiomyopathy.Symptoms and signs of right ventricular dysfunction and pulmonary hypertension should be sought in all patients with newly diagnosed thyrotoxicosis.Thyrotoxicosis should be considered in all cases of right ventricular dysfunction or pulmonary hypertension not readily explained by other causes.Prompt restoration of euthyroidism is warranted in patients with thyrotoxicosis complicated by right ventricular dysfunction with or without pulmonary hypertension to allow timely resolution of the abnormal cardiac parameters before development of overt right heart failure.

Microvascular and macrovascular complications in young-onset type 2 diabetes in a tertiary health institution in Malaysia in comparison with type 1 diabetes patients / Journal of the ASEAN Federation of Endocrine Societies

@#<p style="text-align: justify;"><strong>OBJECTIVES:</strong> To compare the rate of diabetes complications in young-onset type 2 diabetes (T2DM) with type 1 diabetes (T1DM) patients and to examine the relationship between diabetes complications with clinical and metabolic parameters.<br /><strong>METHODOLOGY:</strong> This is a retrospective,comparative study based on electronic medical records review. Young-onset T2DM patients defined as those with disease onset before the age of 40 and T1DM patients were included. Data was collected on demographic and clinical parameters, cardiovascular risks factors, macrovascular and microvascular complications.<br /><strong>RESULTS:</strong> There were 194 young-onset T2DM and 45 T1DM subjects. Despite similar glycemic profile, more subjects in the T2DM group hadunfavourable cardiovascular risk factors and developedmacro- or microvascular complications than the T1DM group (22 vs. 0%, p< 0.001for macrovascular, 68 vs. 40%, p< 0.001 for microvascular). Afteradjustment ofthe confounders, young-onset T2DM remained an independent predictor for both macrovascular and microvascular complications in the overall cohort (HR= 2.635, p= 0.022).<br /><strong>CONCLUSION:</strong> Young-onset T2DM appeared to be a more aggressive disease compared to T1DM. An aggressive approach should be adopted in treating young-onset T2DM to optimise the cardiovascular risk factors and glycemic control to prevent premature mortality and morbidity.</p>
