Study Overview
Brief Summary
The goal of this clinical trial is to verify whether a cell culture system can be used to evaluate the presence of a factor capable of causing proteinuria in the serum of patients with primary podocytopathies. This system will also be used to evaluate the in vitro efficacy of a combined therapy for the treatment of this disorder.
Researchers will compare samples from patients with primary podocytopathies with those obtained from healthy subjects and patients with other renal disorders.
Participants will be asked to visit the clinic at regular intervals for up to 36 months, and to provide blood and urine samples (and a sample of the discarded plasmapheresis effluent in case the procedure is performed).

Outcomes
Primary Outcomes
Co-culture system capability to distinguish recurrent podocytopathies from healthy subjects
Time Frame: Baseline
The difference in the increase of albumin permeability in the endothelium-podocyte co-culture system after exposure to serum from patients with recurrent podocytopathies and healthy subjects will be compared.
Secondary Outcomes
- In-vitro efficacy of SGLT2-inhibitors and uPAR/FPR-inhibitors on primary podocytopathies(Baseline, 16 weeks and in case of remission/recurrence)
- Co-culture system capability to distinguish recurrent podocytopathies from other glomerular disorders(Baseline)
- Co-culture system reliability in case of podocytopathy remission(Baseline, 16 weeks and in case of remission/recurrence)
