Burosumab, monoclonal antibody targeting fibroblast growth factor 23, is now available for clinical use in children with X-linked hypophosphatemia (XLH). We explored the effects of this treatment in a clinical setting, considering biochemistry, growth, deformity, functionality, quality of life, pain and fatigue.Methods: Clinical, biochemical, radiological and questionnaire data were reviewed at 6 and 12 months(m) for 8 children with XLH starting burosuma...

Adipose tissue is recognized as an active endocrine organ. Cytokines released from adipocytes induce chronic low-grade inflammation, which is linked to the development of cardiovascular diseases and malignancy.In this study, we examined the relationship between baseline adipokines level and incident cancer risk in a community-based cohort of Chinese subjects. Subjects were recruited from the Hong Kong Cardiovascular Risk Factors Prevalence Study 2(CRISPS 2) cohort. Those with ...

Sporadic somatostatinomas are rare neuroendocrine tumours (NETs), classically presenting with hyperglycaemia, cholelithiasis and steatorrhoea. The mainstay of treatment is surgical resection; other aspects of management remain uncertain. We report 3 cases. Case 1: A 55 year-old female presented with abdominal discomfort and steatorrhoea. Computed tomography (CT) demonstrated a 9 cm pancreatic mass. Biopsy suggested a NET. Somatostatin (SMS) was 160 pmol/l (normal 0-150)...

Objectives: Molecular diagnostic tests for indeterminate thyroid nodules (ITNs) are marketed based on negative predictive value (NPV) and benign call rate. Arguments that unnecessary surgeries are avoided based on NPV/BCR incorrectly assume that all ITNs would undergo diagnostic surgery in the absence of molecular testing. In our practice with centralized triage and cytopathology the resection and malignancy rate, respectively, were 21% and 26% for AUS/FLUS and 56% and 43% for...

Background: 177Lu-DOTATATE is an FDA and Health Canada-approved treatment option for metastatic, progressive GEPNET patients. 177Lu-DOTATATE is now often considered the treatment of choice for small bowel/midgut patients who have progressed on somatostatin analogs (SSA). Despite 177Lu- DOTATATE’s impressive disease stabilization, many patients will eventually progress. Progression after prior use of PRRT does not necessarily render these tumors resistant to future PRRT tr...

Background & aims: Data comparing the effect of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on type-2 diabetes (T2D) outcomes and the relationship between weight-loss (WL) and T2D remission are limited. Thus, we undertook a retrospective study of patients with obesity and T2D who underwent RYGB or SG and examined the relationship between 2-year (2y) post-surgery T2D and WL outcomes.Material & methods: Patients who underwent RYGB (...

Objectives: Obesity is associated with an increase in cardiovascular risk. We investigated whether the measurement of obesity-related biomarkers could enhance the prediction of cardiovascular (CVD) events when used in conjunction with traditional risk factors.Methods: We studied subjects in the Hong Kong Cardiovascular Risk Factors Prevalence Study 2 (CRISPS 2) cohort without previous cardiovascular disease. Baseline serum levels of several biomarkers kn...

Introduction: Joint British Diabetes Societies Inpatient (JBDS-IP) recommended reducing fixed-rate intravenous insulin infusion (FRIII) rate to 0.05units/kg/hr when blood glucose falls <14 mmol/l to avoid hypoglycaemia during diabetes-related ketoacidosis (DKA).Aim: We studied the impact of guideline change on complications and outcomes of DKA.Methods: We included all DKA episo...

MicroRNAs (miRNAs) are small non-coding RNAs that repress protein production post-transcriptionally. MiRNAs play crucial roles in metabolism, endocrine cells development and in processes altered in T2D, such as insulin secretion. MiR-125b controls proliferation, apoptosis and differentiation of various cell types, although its role in β-cells remains unclear. Recent studies show an association between high levels of circulating miR-125b and hyperglycaemia (HbA1c) in predi...

Background: The number of women seeking bariatric surgery in order to improve their fertility is increasing. Current guidelines recommend that pregnancy should be delayed for at least 1 year post-surgery. However, there are limited data regarding pregnancy outcomes post-surgery, particularly for sleeve gastrectomy.Methods: We performed a single-centre, retrospective cohort study of pregnancies in women post-bariatric surgery. Surgical and maternity recor...
