Managing Asthma and Diabetes: Insights from Recent Study
Key Takeaways
- DPP-4 inhibitors and GLP-1 receptor agonists are linked to a higher incidence of asthma exacerbations requiring systemic corticosteroids compared to metformin.
- Patients on SGLT2 inhibitors have similar asthma exacerbation rates as those on metformin, while only DPP-4 inhibitors are significantly correlated with more hospitalizations.
- The study suggests potential anti-inflammatory benefits of metformin and SGLT2 inhibitors in asthma control, but results are limited by its observational design and Japanese-only patient data.

Introduction
A recent retrospective population-based cohort study from Japan has shed light on the connection between asthma exacerbations and different classes of antidiabetic agents in patients with type 2 diabetes. The study compared the incidence of acute exacerbations in patients taking metformin versus newer diabetes agents such as DPP-4 inhibitors, GLP-1 receptor agonists, and SGLT2 inhibitors.
Research Findings
The study revealed that both DPP-4 inhibitors and GLP-1 receptor agonists were associated with a higher incidence of exacerbations requiring systemic corticosteroids when compared to metformin. On the other hand, patients taking SGLT2 inhibitors had similar incidences of asthma exacerbations requiring systemic corticosteroids as those taking metformin. Interestingly, only DPP-4 inhibitors were significantly associated with a higher incidence of exacerbations leading to hospitalization.
Implications of the Study
The findings of the study provide valuable insights into the management of asthma and diabetes in patients. While metformin has long been the first-line treatment for type 2 diabetes, guidelines now recommend considering GLP-1 agonists or SGLT2 inhibitors as first-line drugs for patients with specific complications. The study suggests that the anti-inflammatory effects of these antihyperglycemic drugs, along with improvements in glycemic control, may play a role in better asthma control and management.
Expert Opinion and Limitations
Experts have noted that the mechanism of asthma control is complex, and the study's results challenge previous assumptions about the effects of novel antidiabetic medications on asthma. While SGLT2 inhibitors were expected to be effective for controlling asthma, the study showed that DPP-4 inhibitors and GLP-1 receptor agonists did not provide the same level of asthma control. However, it is important to consider that the study's observational design and inclusion of patients only from Japan may impact the generalizability of the findings.
