The Nephrotic Syndrome Study Network (NEPTUNE) is a North American multicenter collaborative consortium established to develop a translational research infrastructure for nephrotic syndrome. This includes a longitudinal observational cohort study, a pilot and ancillary study program, a training program, and a patient contact registry. NEPTUNE will enroll 450 adults and children with minimal change disease, focal segmental glomerulosclerosis, and membranous nephropathy for detailed clinical, histopathological, and molecular phenotyping at the time of clinically indicated renal biopsy. Initial visits will include an extensive clinical history, physical examination, collection of urine, blood and renal tissue samples, and assessments of quality of life and patient-reported outcomes. Follow-up history, physical measures, urine and blood samples, and questionnaires will be obtained every 4 months in the first year and biannually, thereafter. Molecular profiles and gene expression data will be linked to phenotypic, genetic, and digitalized histological data for comprehensive analyses using systems biology approaches. Analytical strategies were designed to transform descriptive information to mechanistic disease classification for nephrotic syndrome and to identify clinical, histological, and genomic disease predictors. Thus, understanding the complexity of the disease pathogenesis will guide further investigation for targeted therapeutic strategies.

    Some cases of nephrotic syndrome in focal and segmental glomerulosclerosis (FSGS) are associated with a circulating factor, the FSGS permeability factor (FSPF). Galactose has a high affinity for FSPF, and experimental data suggest that it could reduce its activity. We describe the case of a...

    An interview with nephrologist Fernando C. Fervenza is presented. Doctor Fervenza says that focal segmental glomerulosclerosis (FSGS) is a common form of glomerular disease, which causes nephrotic syndrome. He mentions that studies of renal biopsy archives in the U.S. suggest the increase of...
