NCT04980092

Brief Summary

This observational study aims to assess kidney function through direct glomerular filtration rate (GFR) using iohexol clearance, compared to estimated GFR based on creatinine and cystatin C equations. Kidney function will also be evaluated through renal fibrosis biomarkers. Kidney function will be correlated to body composition, muscle turnover biomarkers, and bone micro-architecture.
