Kidney Fat in Type 2 Diabetes and the Effects of Ezetimibe

• Status: Active, not recruiting
• Trial end date: 2022-06-01
• Target enrollment: 0
• Participant gender: All

Summary

In this study, we seek to explore the importance of fat accumulation in the kidneys in relation to diabetic kidney disease (DKD). To do this, we conduct an intervention trial in individuals with type 2 diabetes (T2D) and DKD where we investigate whether the inhibition of intestinal cholesterol absorption with ezetimibe affects albuminuria (a strong risk factor for diabetic complications) and kidney fat accumulation. At the same time and to confirm that kidney fat accumulation is, in fact, abnormal in T2D and DKD, we conduct a cross-sectional study in which we compare kidney fat accumulation in participants at baseline from the intervention trial with a group of individuals with T2D and no DKD and a group of healthy individuals.

Criteria

Inclusion criteria for the intervention trial

• No UACR ≥ 3000mg/g in history

• Current or recent (within 3 months) treatment with ezetimibe

• Initiation or adjustment in dosage within 1 month of an angiotensin-converting enzyme (ACE) inhibitor, angiotensin II receptor blocker (ARB), glucagon-like peptide-1 receptor (GLP-1RA) agonists, sodium-glucose cotransporter 2 (SGLT-2) inhibitors or anti-dyslipidemia drug, e.g. a statin

• Any contraindication to MR-examination (e.g. magnetic foreign body that cannot easily be removed from the body prior to the examination, claustrophobia or body size not compatible with the scanner)
