Official Title: Effect of Galactose on Permeability Factor in Patients With Focal Segmental Glomerulosclerosis (FSGS)

Brief Summary: This study is a proof-of-concept clinical study designed to test the hypothesis that oral administration of galactose can lower the level of a circulating factor that increases glomerular permeability to albumin in patients with resistant FSGS.

Detailed Summary:

Patients with resistant FSGS have persistent proteinuria and a high risk of progression to end stage kidney disease (ESKD). A circulating factor that increases glomerular permeability to albumin (Palb) has been detected in over 50% of these patients. While the molecular identity of the factor has not been fully established, in vitro studies and limited clinical experience suggest that galactose can reduce the level of the FSGS permeability factor.

This study is a pilot study to determine if oral administration of galactose can lower the circulating level of the FSGS permeability factor.

Two groups of patients with biopsy proven primary FSGS who are resistant to steroids and one other immunosuppressive agents will be studied:

l. FSGS, pre-ESKD 2. FSGS, with ESKD on renal replacement therapy

The only eligibility factor is presence of the FSGS permeability factor.

Five patients will be included in each group.

The experimental intervention is administration of galactose, orally, 0.2 g/kg body weight/dose twice daily. the duration of treatment will be 28 days,.

Patients will be seen on days 0, 14, and 28 of treatment. They will be seen at week 8, 16 and 24 after discontinuation of the galactose.

Physical examination and routine laboratory tests (SMAC, CBC, urine protein:creatinine ratio in an early morning sample) will be done at each visit. The FSGS permeability factor will be assayed at days 0 and 28 of treatment and 6 months after discontinuation of the galactose. The permeability factor will be tested in the laboratory of Virgini
