Polycystic ovary syndrome (PCOS) affects many women of reproductive age, including ovarian and metabolic dysfunction. Major therapeutic goals include weight loss and improved insulin resistance. The effects of weight loss and increased insulin sensitivity of glucagon-like peptide-1 (GLP-1) receptor agonists provide another opportunity and pathway for the treatment of PCOS patients, especially those with metabolic abnormalities. This paper reviews the metabolism and reproductive outcomes about GLP-1 receptor agonists for PCOS by searching for literatures of clinical trials from PubMed in the past 10 years, in oder to provide new ideas and clinical evidence for clinical treatment of PCOS.
Diabetic retinopathy (DR) is one of the most serious complications of diabetes mellitus. Severe diabetic macular edema or proliferative retinopathy may lead to impaired vision or even blindness in diabetic patients. The glucagon-like peptide-1 receptor agonist (GLP-1RA) is now commonly used as novel glucose-lowering agents in the clinical management of type 2 diabetes, but the rapid glycaemic changes associated with the use of the GLP-1RA may aggravate the risk of an increase in the occurrence of short-term potential DR. Potential effects and mechanisms of DR include oxidative stress, vascular endothelial growth factor, inflammation, retinal neurodegeneration, and other cytokines.Whether GLP-1RA leads to the increased risk of DR remains controversial. More basic and clinical studies are needed with the aim of further clarifying the correlation between GLP-1RA and DR risk.
Diabetic retinopathy (DR) is one of the most frequent complications of diabetes (T2DM), which is the main eye disease causing blindness in adults in recent years. At present, glucagon-like peptide-1 receptor agonists (GLP-1RA) have become the main drugs used in the treatment of diabetes due to its superior hypoglycemic, lipid-lowering, hypertensive and cardiovascular effects. A large number of studies have shown that GLP-1RA drugs can protect retinal microvascular and optic nerves in the treatment of diabetes through various ways, but some studies have found that GLP-1RA drugs represented by semaglutide may lead to the progress of DR. Therefore, GLP-1RA should be used cautiously for patients who with severe non-proliferative DR or proliferative DR. Regardless of whether T2DM patients are complicated with DR, the fundus retinal condition should be monitored regularly after the use of GLP-1RA drugs, and timely countermeasures should be taken when DR occurs and develops. The benefits of GLP-1RA used by diabetes patients are obvious to all, and scientific and rational drug use can prevent the occurrence and progress of DR, which can better benefit DR Patients.
