Transformative Research in Diabetic Nephropathy 2.0: A Proof of Principle Study of SGLT2 Inhibitors (TRIDENT 2.0)

OBSERVATIONAL
Conditions
Summary
The goal of this observational study is to learn more about kidney health in adults with diabetic kidney disease and other groups. Researchers will study kidney tissue and other samples. They want to learn how sodium-glucose cotransporter-2 (SGLT2) inhibitors, a type of diabetes medicine, may affect the kidneys. People can join only if they are already having a kidney biopsy or kidney surgery as part of their regular medical care. The main questions this study aims to answer are: * Do people who take SGLT2 inhibitors show different biological patterns in kidney tissue than similar people who do not take them? * Are these kidney tissue patterns linked with how kidney health changes over time? Researchers will compare participants who take SGLT2 inhibitors with similar participants who do not take these medicines. Participants will: Let researchers use one stored slide of kidney tissue from their regular care (no extra research biopsy) Give a blood sample and a urine sample Let researchers review medical record information over time
Eligibility
Inclusion Criteria4
- Age ≥18 years
- eGFR ≥10 ml/min/1.73 m2 based on the 2021 race-free CKD-EPI equation13
- Underwent a clinically indicated kidney biopsy, living donor biopsy, or nephrectomy (non-tumor adjacent tissue available).
- Able and willing to provide informed consent for release of one pathology and clinical data abstraction.
Exclusion Criteria3
- Inability to provide informed consent.
- Archived biopsy or surgical tissue unavailable for slide preparation.
- Any local institutional policy that prohibits release of H\&E slides for research.
Interventions
Standard-of-care exposure to sodium-glucose cotransporter 2 inhibitors documented from medication history. Participants are not assigned therapy. Exposure status is used for observational comparisons of kidney tissue molecular and histopathologic features.
Standard-of-care exposure to renin-angiotensin-aldosterone system blockade documented from medication history for observational comparisons.
Standard-of-care exposure documented from medication history for observational comparisons.
Standard-of-care exposure documented from medication history for observational comparisons.
