Objectives

Narrative objectives1

Nephrotic syndrome is a syndrome characterized by massive urinary protein leakage and hypoproteinemia (hypoalbumin) due to increased protein permeability caused by renal glomerular engagement disorders, and the cause of primary nephrotic syndrome is not known. Although steroids are the drug of choice for first-line treatment, many patients have relapsed, and the side effects of continuous steroids and concomitant use of immunosuppressive drugs are problematic. In this situation, the aim of this study is to explore and identify biomarkers for the etiology and clinical course of adult-onset nephrotic syndrome (frequent relapses or steroid-dependent) by means of immunodiversity analysis (TCR/BCR repatea analysis).Specifically, by using specimens from patients participating in a clinical trial (IDEC-C2B8-aNS1) of rituximab for the prevention of relapse in adult-onset nephrotic syndromes (frequent relapses or steroid dependence), we will search for and identify biomarkers related to the prediction of efficacy or the occurrence of adverse effects, as well as for the clinical course of the disease.
