Metabolomic insights into maternal and neonatal complications in pregnancies affected by type 1 diabetes.

AIMS/HYPOTHESIS: Type 1 diabetes in pregnancy is associated with suboptimal pregnancy outcomes, attributed to maternal hyperglycaemia and offspring hyperinsulinism (quantifiable by cord blood C-peptide). We assessed metabolomic patterns associated with risk factors (maternal hyperglycaemia, diet, BMI, weight gain) and perinatal complications (pre-eclampsia, large for gestational age [LGA], neonatal hypoglycaemia, hyperinsulinism) in the Continuous Glucose Monitoring in Women with Type 1 Diabetes in Pregnancy Trial (CONCEPTT). METHODS: A total of 174 CONCEPTT participants gave ≥1 non-fasting serum sample for the biorepository at 12 gestational weeks (147 women), 24 weeks (167 women) and 34 weeks (160 women) with cord blood from 93 infants. Results from untargeted metabolite analysis (ultrahigh performance LC-MS) are presented as adjusted logistic/linear regression of maternal and cord blood metabolites, risk factors and perinatal complications using a modified Bonferroni limit of significance for dependent variables. RESULTS: Maternal continuous glucose monitoring time-above-range (but not BMI or excessive gestational weight gain) was associated with increased triacylglycerols in maternal blood and increased carnitines in cord blood. LGA, adiposity, neonatal hypoglycaemia and offspring hyperinsulinism showed distinct metabolite profiles. LGA was associated with increased carnitines, steroid hormones and lipid metabolites, predominantly in the third trimester. However, neonatal hypoglycaemia and offspring hyperinsulinism were both associated with metabolite changes from the first trimester, featuring triacylglycerols or dietary phenols. Pre-eclampsia was associated with increased abundance of phosphatidylethanolamines, a membrane phospholipid, at 24 weeks. CONCLUSIONS/INTERPRETATION: Altered lipid metabolism is a key pathophysiological feature of type 1 diabetes pregnancy. New strategies for optimising maternal diet and insulin dosing from the first trimester are needed to improve pregnancy outcomes in type 1 diabetes.

Older People With Type 2 Diabetes-Individualising Management With a Specialised Community Team (OPTIMISE): Perspectives of Participants on Care.

Despite the high prevalence of diabetes in older people, there is limited information on optimal methods to support their diabetes management, including how to incorporate technology. This article reports on the results of semi-structured interviews with 41 adult participants with type 2 diabetes (mean age 74 ± 7 years) on their perspectives of a new model of care (the Older People With Type 2 Diabetes-Individualising Management With a Specialised Community Team [OPTIMISE] program) for older people with type 2 diabetes. The OPTIMISE program involved telemedicine consultations, home visits by a credentialed diabetes educator, and intermittent flash glucose monitoring. Human connection and relationships were key to the positive perspectives expressed by participants in this program that used technology to enhance the care of older people in their homes.

An overview of COVID-19 in people with diabetes: Pathophysiology and considerations in the inpatient setting.

INTRODUCTION: The coronavirus disease (COVID-19) pandemic has continued to have a devastating impact on health worldwide. There has been a rapid evolution of evidence, establishing an increased risk of morbidity and mortality associated with diabetes and concurrent COVID-19. The objective of this review is to explore the current evidence for inpatient assessment and management of diabetes during the COVID-19 pandemic and highlight areas requiring further exploration. METHODS: A literature search of databases was conducted to November 2020 using variations on keywords SARS-CoV-2, COVID-19, SARS, MERS and diabetes. Information relating to the impact of diabetes on severity of COVID-19 infection, the impact of COVID-19 infection on diabetes management and diabetes-related complications was integrated to create a narrative review. DISCUSSION: People with diabetes and COVID-19 are at an increased risk of morbidity and mortality. It is important that people with both known and previously unrecognised diabetes and COVID-19 be promptly identified and assessed during acute illness, with close monitoring for clinical deterioration or complications. People with diabetes may require titration or alteration of their glycaemic management due to the potential for worse outcomes with hyperglycaemia and COVID-19 infection. Comprehensive discharge planning is vital to optimise ongoing glycaemic management. CONCLUSION: Further understanding of the risk of adverse outcomes and optimisation of glycaemic management for people with diabetes during COVID-19 is required to improve outcomes. Increased glucose and ketone monitoring, substitution of insulin for some oral anti-hyperglycaemic medications and careful monitoring for complications of diabetes such as diabetic ketoacidosis should be considered.

Considerations for people with diabetes during the Coronavirus Disease (COVID-19) pandemic.

INTRODUCTION: The severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) continues to cause havoc globally, resulting in unprecedented healthcare, societal and economic disruption. People with diabetes have been shown to be at higher risk of complications and death when exposed to pneumonia, influenza and other coronaviruses. Despite pandemic scale infection, there is currently limited understanding on the potential impact of coronavirus disease (COVID-19) on people with diabetes. AIMS: (1) To characterise the outcomes of COVID-19 for people with diabetes and (2) add value to current recommendations for healthcare providers and people with diabetes to encourage optimal management. METHODS: A search of PubMed, Embase and MEDLINE to March 2020 was undertaken, using search terms pertaining to diabetes, coronavirus and acute respiratory distress syndrome (ARDS). We briefly reviewed the epidemiology and pathophysiology of SARS-CoV-2 in the context of diabetes. CONCLUSION: People with diabetes are at greater risk of severe infection and death with COVID-19. COVID-19 has significantly impacted the daily lives of individuals living with diabetes through financial implications, food and medication scarcity and its burden on mental health. In Australia, delivery of medical care has been adapted to reduce the risk of transmission, with a particular emphasis on telehealth and remote monitoring.

Beware Ketoacidosis with SGLT2 Inhibitors in Latent Autoimmune Diabetes of the Adult.

BACKGROUND: Sodium-glucose co-transporter-2 (SGLT2) inhibitors are increasingly used for the treatment of type 2 diabetes, but have been associated with ketoacidosis. METHODS/RESULTS: We report a case series of three patients with latent autoimmune diabetes of the adult who presented with ketoacidosis, including one case with normal blood glucose levels, in the context of SGLT2 inhibitor use. CONCLUSIONS: Sodium-glucose co-transporter-2 inhibitors should be used with caution and close clinical monitoring in patients with latent autoimmune diabetes of the adult. A clinical risk score permits targeted autoantibody testing and should be undertaken prior to commencement of SGLT2 inhibitors or cessation of insulin.

Combination phentermine and topiramate for weight maintenance: the first Australian experience.

OBJECTIVE: To investigate the safety, tolerability and efficacy of combination phentermine and topiramate therapy for maintenance of weight loss. DESIGN, SETTING AND PATIENTS: Retrospective audit of patients attending the Austin Health Weight Control Clinic who were dispensed phentermine-topiramate between 22 January 2010 and 16 July 2012 and after reaching a target weight by following a very low energy diet (VLED). Data collection continued until July 2013. MAIN OUTCOME MEASURES: Number of patients who ceased pharmacotherapy; duration of use of pharmacotherapy; types and numbers of adverse effects; and mean weight and blood pressure measurements at the initial visit, the end of the VLED and the last observation during pharmacotherapy. RESULTS: Data were available for 103 patients who were dispensed phentermine-topiramate; 61 patients ceased combination pharmacotherapy before the end of the data collection period, 41 due to adverse effects (eg, paraesthesia, cognitive changes, dry mouth and depression). The mean duration of use of pharmacotherapy was 10 months. Mean weight decreased by 10% due to the VLED (from 135.5 kg to 122.5 kg) and this loss was maintained. For 30 patients who continued on phentermine-topiramate, the mean duration of pharmacotherapy was 22 months and the mean weight decreased by 6.7 kg between the end of the VLED and the last observation during pharmacotherapy. CONCLUSION: Phentermine-topiramate therapy was not well tolerated; more than half of the patients in our study stopped taking it because of adverse effects, and more than half of the adverse events reported were ascribed to topiramate. However, in those able to continue with pharmacotherapy, the combination was efficacious for both maintenance of weight loss and ongoing weight loss.
