Investigating metabolic and lipid profiles in diabetic eye disease

Investigating the Metabolic and Lipidomic Profiles That Are Associated With Varying Grades of Diabetic Maculopathy and Retinopathy in South Wales

Observational Hywel Dda Health Board · NCT06914778

This study is trying to see how blood and urine samples from people with diabetes relate to eye damage caused by diabetic eye disease and if gut bacteria play a role in this.

What this trial studies

This observational study aims to recruit individuals with diabetes and varying stages of diabetic eye disease to analyze blood and urine samples for metabolic and lipidomic profiles. The research will explore the relationship between these profiles and the damage to the retina caused by diabetic retinopathy and diabetic macular edema. Additionally, the study will examine gut bacteria that may influence eye disease through circulating chemicals. Participants will have their medical records reviewed to support the findings.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 80 with a diagnosis of type 2 diabetes mellitus.

Not a fit: Patients under 18 or over 80, those with prior intravitreal treatments for diabetic macular edema, or those with known infectious diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of diabetic eye diseases, potentially improving patient outcomes.

How similar studies have performed: While there is limited evidence from small population studies, this approach is relatively novel and has not been extensively tested in broader cohorts.
