Introduction: Non-diabetic hypoglycemia in older adults warrants careful evaluation across insulin-mediated and noninsulin-mediated causes. We present a challenging case of insulin autoimmune syndrome (IAS; Hirata’s syndrome). Case: An 85-year-old female presented with severe hypoglycemia (capillary blood glucose [CBG] 1.8 mmol/L) with reduced consciousness, preceded by 2 months of recurrent dizziness relieved by food intake. Appetite and weight were stable. Past medical history included stage 3 chronic kidney disease and osteoporosis, but no diabetes. Medication review revealed a recent 2-week course of traditional supplement, long-term Neurobion®, but no agents with recognized hypoglycemic potential. Physical examination showed a moderately built elderly female with a body mass index of 24.3 kg/m² and no Cushingoid features. Recurrent hypoglycemia (CBG nadir 1.5 mmol/L) occurred in both fasting and postprandial states, fulfilling Whipple’s triad. Baseline investigations showed an estimated glomerular filtration rate of 42 mL/min/1.73 m², AM cortisol of 700 mmol/L, and unremarkable liver and thyroid function tests. During a hypoglycemic episode (CBG 2.3 mmol/L), plasma insulin and C-peptide were inappropriately raised at 203.6 mU/L (reference interval [RI]: 3.0– 25.0) and 33 ng/mL (RI: 0.9–7.1), respectively, confirming endogenous hyperinsulinemic hypoglycemia. Polyethylene glycol precipitation showed 21% insulin recovery, raising suspicion for an autoimmune cause. Elevated insulin autoantibodies (175 AU/mL; RI <20) confirmed IAS. Computed tomography of the abdomen and endoscopic ultrasound excluded a pancreatic neuro-endocrine tumor. Nutritional management comprising frequent low glycemic index feeds and uncooked cornstarch was commenced. Diazoxide 100 mg TDS caused fluid overload and severe hyponatremia, while hypoglycemia persisted at lower doses, necessitating discontinuation. Subcutaneous octreotide 100 mg QID was required to control hypoglycemia. Prednisolone 30 mg BD improved glycemic stability. Insulin autoantibodies titer remained 175 AU/mL at 2 weeks; reassessment was conducted at 4 weeks with consideration for biologics if persistent. : doses, necessitating discontinuation. Subcutaneous octreotide 100 mg QID was required to control hypoglycemia. Prednisolone 30 mg BD improved glycemic stability. Insulin autoantibodies titer remained 175 AU/mL at 2 weeks; reassessment was conducted at 4 weeks with consideration for biologics if persistent. Conclusion Endogenous hyperinsulinemic hypoglycemia, after excluding insulinoma, should raise suspicion for IAS. Management includes removing triggers, supportive care, and immunomodulatory therapy in severe cases.

People with type 2 diabetes mellitus have increased risk of chronic kidney disease and atherosclerotic cardiovascular disease. Improved care delivery and implementation of guideline-directed medical therapy have contributed to the declining incidence of atherosclerotic cardiovascular disease in high-income countries. By contrast, the global incidence of chronic kidney disease and associated mortality is either plateaued or increased, leading to escalating direct and indirect medical costs. Given limited resources, better risk stratification approaches to identify people at risk of rapid progression to end-stage kidney disease can reduce therapeutic inertia, facilitate timely interventions and identify the need for early nephrologist referral. Among people with chronic kidney disease G3a and beyond, the kidney failure risk equations (KFRE) have been externally validated and outperformed other risk prediction models. The KFRE can also guide the timing of preparation for kidney replacement therapy with improved healthcare resources planning and may prevent multiple complications and premature mortality among people with chronic kidney disease with and without type 2 diabetes mellitus. The present review summarizes the evidence of KFRE to date and call for future research to validate and evaluate its impact on cardiovascular and mortality outcomes, as well as healthcare resource utilization in multiethnic populations and different healthcare settings.

Aim and design: This systematic review aimed to estimate the prevalence of online natural health products (NHPs) purchases among consumers. Data Sources: Four databases (PubMed, Science Direct, Scopus and Web of Sciences) were searched for articles published up to July 1, 2021. Review Method: Studies included were those reporting the prevalence of online NHPs purchases, those excluded were case reports, commentaries, letters, editorials, review articles, theses and non-English studies. The risk of bias of selected studies was assessed using the Joanna Briggs Institute’s checklist, and the pooled prevalence of online NHPs purchases was generated using the random-effect model. Results: A total of 30 studies were included in the meta-analysis, representing a total of 40,535 respondents. The pooled prevalence of online NHPs purchases was estimated at 7.60% (95% CI: 5.49, 10.01). Prevalence was higher in studies conducted in recent years, among physically active populations and when sports nutrition was included within the scope of NHPs. More than half of the selected studies have a moderate risk of bias, and considerable heterogeneity was observed across the selected studies. Conclusion and Impact: Online purchases of NHPs are not common among consumers, but they have become more common in recent years. A wide range of NHPs were investigated across studies, which may have contributed to the considerable heterogeneity reported in this review. It is suggested that future studies investigating online NHPs purchases consider reporting individual prevalence statistics specific to each NHP type, to facilitate meaningful comparisons between studies.
