Diet Intervention in Food Sensitive Patients With IgA Nephropathy (DIIGA)

September 16, 2010 updated by: Uppsala University Hospital

A Pilot Study of 6 Months Diet Intervention in Food Sensitive Patients With IgA Nephropathy

The purpose of this study is to assess whether a tailored diet, eliminating antigens to which IgA nephropathy patients have demonstrated sensitivity, will have an effect on proteinuria, renal function and other immunological variables.
