title: FSGS permeability factor-associated nephrotic syndrome: remission after oral galactose therapy.
abstract: 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 48-year-old male with a nephrotic syndrome found to be resistant to corticosteroids, immunosuppression and plasmaphaeresis. The patient was given oral galactose as a last resort treatment, which was followed by a remission of his nephrotic syndrome that correlated with a reduction of FSPF activity. This case is the first report of a long-standing remission of an FSPF-associated nephrotic syndrome on oral galactose therapy.
