OBJECTIVEImpaired awareness of hypoglycemia (IAH) increases the risk of severe hypoglycemia (SH) sixfold and affects 30% of adults with type 1 diabetes (T1D). This systematic review and meta-analysis looks at the educational, technological, and pharmacological interventions aimed at restoring hypoglycemia awareness (HA) in adults with T1D. RESEARCH DESIGN AND METHODSWe searched The Cochrane Library, MEDLINE, Embase, Science Citation Index Expanded, Social Sciences Citation Index, PsycINFO, and CINAHL from inception until 1 October 2014. Included studies described HA status at baseline. Outcome measures were SH rates, change in HA, counterregulatory hormone responses, and glycemic control. RESULTSForty-three studies (18 randomized controlled trials, 25 before-and-after studies) met the inclusion criteria, comprising 27 educational, 11 technological, and 5 pharmacological interventions. Educational interventions included structured diabetes education on flexible insulin therapy, including psychotherapeutic and behavioral techniques. These were able to reduce SH and improve glycemic control, with greater benefit from the latter two techniques in improving IAH. Technological interventions (insulin pump therapy, continuous glucose monitoring, and sensor-augmented pump) reduced SH, improved glycemic control, and restored awareness when used in combination with structured education and frequent contact. Pharmacological studies included four insulin studies and one noninsulin study, but with low background SH prevalence rates. CONCLUSIONSThis review provides evidence for the effectiveness of a stepped-care approach in the management of patients with IAH, initially with structured diabetes education in flexible insulin therapy, which may incorporate psychotherapeutic and behavioral therapies, progressing to diabetes technology, incorporating sensors and insulin pumps, in those with persisting need.

Coronavirus disease 2019 (COVID‐19) is a global pandemic that is caused by a novel coronavirus, severe acute respiratory syndrome coronavirus‐2. Data from several countries have shown higher morbidity and mortality among individuals with chronic metabolic diseases, such as diabetes mellitus. In this review, we explore the contributing factors for poorer prognosis in these individuals. As a significant proportion of patients with COVID‐19 also have diabetes mellitus, this adds another layer of complexity to their management. We explore potential interactions between antidiabetic medications and renin–angiotensin–aldosterone system inhibitors with COVID‐19. Suggested recommendations for the use of antidiabetic medications for COVID‐19 patients with diabetes mellitus are provided. We also review pertinent clinical considerations in the management of diabetic ketoacidosis in COVID‐19 patients. In addition, we aim to increase clinicians’ awareness of the metabolic effects of promising drug therapies for COVID‐19. Finally, we highlight the importance of timely vaccinations for patients with diabetes mellitus.

The benefits of continuous subcutaneous insulin infusion with regard to improving glycaemic control and reducing hypoglycaemia frequency, along with improvement in hypoglycaemia awareness without deterioration in glycaemic control, can be sustained over several years in clinical practice.
