Review of Reviews: a virtual issue
Richard IG Holt*
For the last two years Diabetes, Obesity and Metabolism has produced a freely available virtual issue of a selection of reviews that were accepted in the previous year. Given its popularity judging by the number of downloads, we have decided to continue with this for a further year. Again we have accepted a wide breadth of articles discussing different aspects of the therapeutics of diabetes, obesity and metabolism.
Some have had a broad focus, such as treatment of older people with diabetes (1;2) and biosimilar insulin (3), while others have described the actions of individual drugs (4-6). There have been articles considering the safety of drugs (2;7-10) or the use of drugs in special populations (11-13). New drug targets (14-16), lifestyle issues (17) and pharmacological prevention of diabetes (18) have all been included. Alas not all of these articles could be contained within the virtual issue and again I have made a personal choice for inclusion.
For many years, specific insulin analogues have been made by single manufacturers but as they are coming to the end of their patents, biosimilar insulins made by other companies are likely to enter clinical practice in the near future. The implication of this development for clinical practice and regulation are elucidated in the review by deVries and colleagues (3).
Diabetes affects 10–30% of elderly people worldwide and 40% of those with diabetes are elderly, at least in high income countries. Diabetes in older people may present significant challenges to the patient and their healthcare team, particularly in the context of associated co-morbidities and often complex clinical decision-making. This issue is sensitively reviewed by Valencia and colleagues (1). Avoidance of hypoglycaemia is a key goal in the elderly and the role of DPP-4 inhibitors in preventing this burden is described by Avogaro and co-authors (2).
Safety continues to dominate our choices of treatments, particularly in view of the on-going debate about certain diabetes drugs and cardiovascular risk. Both the effects of GLP-1 receptor agonists and sulphonylurea drugs on cardiovascular disease were reviewed last year (8;10).
It was good news to hear last year that diabetes is no longer the commonest cause of blindness in people of working age in the UK. Much of this is a testament to improved glucose and blood pressure control as well as timely screening for retinopathy. Nevertheless it remains an important clinical problem and the new treatments reviewed by Das et al are needed to improve the vision of people with significant retinopathy (12).
Co-morbidity of type 1 diabetes with coeliac disease creates additional challenges for patient and healthcare professional alike. Early initiation of a gluten-free diet is associated with improved complications, growth and bone density and may even prevent additional autoimmune diseases. Leonard and colleagues have described what clinicians need to do to identify and treat those with coeliac disease adequately (11).
Obesity remains a challenge for those with type 2 diabetes. Although some of the newer treatments are associated with less weight gain than previously, lifestyle intervention is essential to help people manage their weight. The large Look AHEAD trial showed that an intensive lifestyle intervention led to reduction in weight and HbA1c and improved fitness and cardiovascular risk factors. However, there was no effect on cardiovascular disease event. The implications of this study are discussed by Wing (17).
Prevention of diabetes remains a major goal and although lifestyle interventions are highly effective, they are not suitable for all and drug treatments are needed for some people. However, the current evidence for pharmacological interventions, reviewed by Bethel et al, remains disappointing when long-term hard diabetes outcomes such as complications and mortality are considered (18).
I hope you find this year’s virtual issue as enjoyable as previous years and that it inspires you to consider writing for Diabetes Obesity and Metabolism. I would also encourage you to look up the other reviews that I was unable to include.
