The successful treatment of rapidly progressive idiopathic membranoproliferative glomerulo-nephritis Type 1 in a 4-year-old male pediatric patient

Clin Nephrol. 2010 Oct;74(4):303-7. doi: 10.5414/cnp74303.


A multivariate analysis [4] revealed that the presence of crescent formation on initial biopsy irrespective of type of membranoproliferative glomerulonephritis (MPGN) was independently associated not only with end-stage renal disease but also with post-transplantation recurrence. In this study, we reported on a 4-year-old male pediatric patient requiring hemodialysis due to rapidly progressive idiopathic MPGN Type 1 with severe nephrotic syndrome and extensive cellular crescent formation on initial biopsy. The patient had been treated intravenously (i.v.) with 9 pulses of methylprednisolone, followed by daily prednisolone, resulting in the withdrawal of dialysis within 1 month. However, since active lesions in the second renal biopsy such as cellular crescents still remained and nephrotic range proteinuria had persisted for more than 2 months, the patient received additional 3 i.v. pulses of methylprednisolone, followed by combinations of alternate-day prednisolone, mizoribine, dipyridamole and warfarin, which lead to complete remission in a short-period of time. The patient has been off the combination therapy for 10 months because the third biopsy prior to the termination of this regimen showed decreased inflammatory activity. There is currently no established protocol for children with crescentic MPGN due to a rarity of its clinicopathological presentation. This case report indicates that early treatment with multiple pulses of methylprednisolone followed by the short-term combination therapy may be of benefit for children with rapidly progressive idiopathic MPGN Type 1, even when both diffuse crescentic changes and nephrotic syndrome are present at onset.
