About this trial

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.

Trial outcomes

Primary outcomes

1

Prevalence

To investigate the prevalence of biopsy-proven diabetic nephropathy in individuals with T2DM with severe albuminuria; urine albumin/creatinine ratio (UACR) \>700 mg/g.

Time frame
From baseline to end inclusion (3 years)

Secondary outcomes

1

Improved clinical diagnosis

To investigate whether clinical variables, transcriptomic, proteomic and/or metabolomic profiles as well as genetic variation can predict the presence of diabetic nephropathy in a kidney biopsy.

Time frame
From baseline to end inclusion (3 years)
2

diabetic retinopathy

To describe the sensitivity and specificity of diabetic retinopathy in predicting biopsy-proven diabetic nephropathy

Time frame
From baseline to end inclusion (3 years)
3

Kidney Biopsy

describe the prognostic value of different histological and molecular findings on kidney biopsy in individuals with biopsy-proven diabetic nephropathy

Time frame
From baseline to end of followup (20 years)
4

non-diabetic nephropathy vs. biopsy-proven diabetic nephropathy

describe the prognostic value of different histological and molecular findings on the kidney biopsy in individuals with non-diabetic nephropathy compared to biopsy-proven diabetic nephropathy.

Time frame
From baseline to end of followup (20 years)
