Diabetic Nephropathy in People With Diabetes. Prevalence and Predictive Factors
Biopsy-proven Diabetic Nephropathy in People With Type 2 Diabetes. Prevalence and Predictive Factors
Herlev Hospital
300 participants
Aug 10, 2021
OBSERVATIONAL
Conditions
Summary
a prospective, observational, multi-center study with a cohort of 300 patients with Type 2 diabetes and macroalbuminuria. Prospectively we will collect kidney biopsies and analyse the transciptome of the kidney tissue and other biomarkers from blood, faeces, urine, proteomic- and metabolomic profiles and DNA-variants. Thereby we hope to be able to discover molecular and clinical profiles, that can help us in the diagnosis of DKD, and to identify different risks of progression that can benefit from different forms of personalized treatment.
