This Week in Diabetes & Endocrinology: Sleep Apnea, HIV Metabolic Risk, and New Agonists

This week's research offers a mixed picture regarding digital interventions and lifestyle management. From the New England Journal of Medicine, a trial examined the efficacy of SMS text messaging lifestyle programs for adults with prediabetes. The systematic review and meta-analysis of 4632 adults found that these programs did not significantly improve metabolic outcomes ^[1].

Interpretation of these null results requires caution, suggesting that current text-based approaches may not be sufficient for this population.

Meanwhile, attention shifted to sleep apnea management in Diabetes, obesity & metabolism. A network meta-analysis of 3964 adults with obstructive sleep apnea indicated that CPAP produced the largest reduction in apnea-hypopnea index ^[2].

The authors describe how GLP-1 receptor agonists also improved weight in this group, though they note that safety data for these agents in obstructive sleep apnea are currently lacking.

Elsewhere this week, a separate study in Endocrinology, diabetes & metabolism highlighted the potential of ecnoglutide. A meta-analysis of 1643 adults with type 2 diabetes found that this next-generation GLP-1 agonist significantly reduced HbA1c and body weight ^[3].

Findings suggest that while GI side effects are manageable, the drug warrants consideration for lowering glycated hemoglobin and weight in type 2 diabetes.

We also saw research in The lancet. HIV linking antiretroviral therapy choices to metabolic health. A global cohort study found that switching to integrase inhibitors increased risks for obesity, diabetes, and hypertension over five years ^[4].

However, the study reported that this switching strategy did not increase the risk of major adverse cardiovascular events in people with HIV.

Finally, a post hoc analysis in Circulation journal : official journal of the Japanese Circulation Society explored lipid ratios in high-risk patients. In 5,006 high-risk type 2 diabetes patients with diabetic retinopathy, a high LDL-C to HDL-C ratio was linked to cardiovascular events ^[5].

The authors describe the L/H ratio as a potential risk stratification tool for this specific high-risk subgroup.
