Successful use of rituximab in fibrillary glomerulopathy

Fibrillary glomerulopathy (FG) can occur either alone or co-existing with other proteinuric glomerular disorders. FG has been associated with poor renal outcomes leading to End Stage Renal Disease (ESRD). Since FG is a relatively rare disorder, limited information is available concerning treatment protocols. We present two patients with FG who were treated with rituximab after they had already progressed to stage 3 chronic kidney disease (CKD) with worsening proteinuria. Rituximab therapy resulted in long-term stabilization of renal function.
