The possible effect of anti-diabetic agents GLP-1RA and SGLT-2i on the respiratory system function.

Type 2 Diabetes (T2D) is a chronic disease with increasing incidence and prevalence and serious chronic complications, especially from cardiovascular system. However, other organs can be affected too. Several studies have associated T2D, especially when poorly controlled, with multiple pulmonary diseases. T2D is a common comorbidity among patients with asthma, Chronic Obstructive Pulmonary Disease (COPD), and Obstructive Sleep Apnea Syndrome (OSAS), and it is related to higher respiratory infection incidence, prevalence and severity. Glucagon-like peptide-1 receptor agonists (GLP-1RA) and Sodium-glucose co-transporter-2 inhibitors (SGLT-2i) are novel antihyperglycaemic agents with established cardiovascular benefits. There are also limited studies indicating their potential benefit in respiratory function. The aim of this article is to review data on the impact of GLP-1RA and SGLT-2i on respiratory function and describe the possible clinical benefits. Key findings indicate that GLP-1RA significantly improve lung function in patients with COPD, evidenced by improvements in spirometry measurements. Additionally, both GLP-1RA and SGLT-2i are associated with a decreased risk of severe and moderate exacerbations in COPD patients and have shown potential in reducing the incidence of respiratory disorders, including asthma and pneumonia. The mechanisms underlying these benefits are not yet fully understood and include multiple effects, such as anti-inflammatory action and oxidative stress reduction.
