A case report of atypical anti-glomerular basement membrane disease with membrane hyperplasia lesions
Atypical anti-glomerular basement membrane(GBM)disease is rare,and the atypical anti-GBM disease with membrane hyperplasia lesion is even rarer.The treatment plan for it is not clear.This article reports a case of atypical anti-GBM disease with a negative anti-GBM antibody test,but renal tissue biopsy showed"glomerular membrane hyperplasia lesions with positive IgG linearity",which provides a reference for clinical diagnosis and treatment.The patient exhibited massive proteinuria,hematuria,edema,and renal impairment.After ruling out secondary factors,the patient was diagnosed with"atypical anti-GBM nephritis"by renal tissue biopsy,and was treated with glucocorticoids combined with cyclophosphamide,after which the patient developed a lung infection and acute left heart failure,and received regular hemodialysis treatment.Then the patient progressed to the stage of end-stage renal disease and continued to receive regular hemodialysis treatment.
