Evaluating biomarkers in IgA nephropathy patients

IgA Nephropathy Biomarkers Evaluation Study (INTEREST)

Observational Sun Yat-sen University · NCT02954419

This study is trying to see if certain blood and urine markers can help predict how kidney disease will progress in people with IgA nephropathy who still have normal kidney function.

What this trial studies

This observational cohort study aims to investigate the relationship between blood and urine biomarkers, including genetic variants, and the long-term progression of kidney disease in 2000 Chinese patients diagnosed with IgA nephropathy who have relatively normal kidney function. The study focuses on understanding how these biomarkers can predict outcomes in patients with IgA nephropathy, a common cause of end-stage renal disease in China. By integrating data from whole genomic loci and serum and urine biomarkers, the study seeks to provide insights that could lead to better prognostic tools for managing this condition.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 14 years or older with biopsy-proven primary IgA nephropathy and an eGFR of 60 ml/min/1.73 m2 or higher.

Not a fit: Patients with secondary IgA nephropathy or those whose relatives have been diagnosed with biopsy-proven primary IgA nephropathy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the identification of reliable biomarkers that help predict kidney disease progression in IgA nephropathy patients.

How similar studies have performed: Previous studies have identified genetic loci related to IgA nephropathy, but this study's comprehensive approach to integrating various biomarkers is relatively novel.
