[Two cases report and literature review of IgA nephropathy combined with primary membranous nephropathy].
OBJECTIVE
To describe the clinical and pathological characteristics and prognosis of IgA nephropathy coexisting with membranous nephropathy (MN).


METHODS
Two cases were confirmed to have IgA nephropathy as well as primary MN by immunofluorescence and immuno-electron microscopy for renal biopsy and clinical data. Clinical and pathological manifestations were collected and prognosis was investigated.


RESULTS
The pathological characteristics included IgA deposit in mesangium but IgG deposit in subepithelial site mainly. Two patients presented moderate to heavy proteinuria, minimal hematuria, and normal renal function. During 9 months of follow up, the renal function remained normal.


CONCLUSIONS
The combined form of membranous nephropathy and mesangioproliferative IgA nephropathy was uncommon. The clinical characteristics of the two cases in this study were more similar to those of MN. Coexistence of two kinds of primary glomerulonephritis did not result in a particularly deterioration in clinical outcome.
