This Week in Diabetes & Endocrinology: Triple Therapy and Probiotics

This week's research highlights offer varied perspectives on managing glycemic control across different patient populations. From the New England Journal of Medicine, a trial examined the efficacy of combining three oral agents. A systematic review and meta-analysis of 2,606 adults with type 2 diabetes found that triple oral therapy combining metformin, an SGLT-2 inhibitor, and a DPP-4 inhibitor significantly reduced HbA1c ^[1].

The authors describe that while this approach improves target achievement without increasing overall adverse events, discontinuations due to side effects are higher in this group. Meanwhile, attention turned to adjunctive therapies that might offer modest benefits. A meta-analysis of over 2,000 participants found that probiotics, synbiotics, and berberine produced significant but modest reductions in fasting plasma glucose and HbA1c compared to placebo ^[2].

These findings suggest that these agents could be considered as options for modest glucose lowering in type 2 diabetes. Elsewhere this week, researchers expanded the scope of probiotic research to a younger demographic. In the European journal of pediatrics, a systematic review and meta-analysis synthesized evidence on oral probiotics, prebiotics, or synbiotics in children and adolescents with type 1 diabetes ^[5].

It found significant reductions in glycemic markers, though the authors note that evidence is heterogeneous and specific formulations are not yet established. We also saw research in The Nigerian postgraduate medical journal regarding newer pharmacologic agents. A systematic review and meta-analysis pooled data from real-world studies involving 89,296 adults with type 2 diabetes ^[4].

Tirzepatide was associated with a mean HbA1c reduction of 0.91% and a mean weight reduction, supporting clinical trial findings for HbA1c and weight reduction in type 2 diabetes. Finally, a narrative review in Frontiers in Medicine examined fertility preservation techniques for women of childbearing age with malignant tumors, focusing on Chinese practices ^[3].

Key findings include survival rates of frozen oocytes, indicating that fertility preservation techniques show variable success rates and that multidisciplinary support is crucial.
