Abstract
We report a girl with severe congenital neutropenia who has received long-term granulocyte-colony stimulating factor (G-CSF) therapy and has developed macroscopic hematuria, proteinuria, and decreased renal function associated with biopsy-proven membranoproliferative glomerulonephritis (MPGN) type I. Temporary discontinuation of G-CSF therapy as well as the use of glycosylated G-CSF has resulted in improvement in renal manifestations. We postulate that the MPGN was G-CSF-induced. Long-term G-CSF therapy should be used with great caution and close surveillance of kidney function.
