Fibrillary glomerulonephritis (FGN) is a rare glomerular disease with various etiologies, including idiopathic cases and associations with autoimmune diseases, neoplasms, and viral infections, such as Hepatitis C. We present a case of a patient who developed acute kidney injury (AKI) with atypical clinical features. A subsequent renal biopsy confirmed the diagnosis of FGN, with distinct immunofluorescence staining for DNAJB9. The patient tested positive for Hepatitis C antibodies with an undetectable viral load, indicating a past infection that had self-cleared. This finding prompted further investigation of the association between Hepatitis C and the development of FGN.
纤维性肾小球肾炎(FGN)是一种病因多样的罕见肾小球疾病,包括特发性病例以及与自身免疫性疾病、肿瘤和病毒感染(如丙型肝炎)相关的病例。我们报告一例具有非典型临床特征的急性肾损伤(AKI)患者。随后的肾活检确诊为FGN,DNAJB9免疫荧光染色明显。该患者丙型肝炎抗体检测呈阳性,但病毒载量检测不到,表明既往感染已自行清除。这一发现促使进一步研究丙型肝炎与FGN发生之间的关联。
