BACKGROUND: Anti-glomerular basement membrane (GBM) antibody disease is a rare @entity792 characterized by rapidly progressive @entity631 caused by autoantibodies against the a3-chain of type IV collagen in the GBM. CASE PRESENTATION: An 8-year-old @entity1 with @entity811 and @entity644 due to anti-GBM @entity1310 was diagnosed with @entity811 and @entity644 during a school urine screening program. Her blood pressure and serum @entity1011 levels were normal. Her @entity811 and @entity644 persisted for several months. Since a spot urine protein to @entity1011 ratio was around 7  g/g Cre, a percutaneous renal biopsy was performed. Immnofluorescent staining demonstrated a linear pattern for immunoglobulin G along the entire GBM. Chest computed tomography was normal. Anti-GBM antibody assays were reported as slightly raised; thus, the diagnosis was @entity8 with normal renal function. Treatment included plasma exchange, intravenous high-dose @entity1667 , and @entity786 as a mainstay medication. The treatment was rapidly effective with an immediate decrease in anti-GBM titers and @entity644 . CONCLUSIONS: Cases of @entity8 with normal renal function in @entity1 are rare. Treatment in @entity1 has not been established; therefore, clinicians need to carefully select an effective treatment because the prognosis is poor.
