Lipoprotein glomerulopathy resulting from compound heterogeneous mutations of APOE gene: A case report
RATIONALE: Lipoprotein glomerulopathy (LPG) is a rare glomerular disease characterized by the deposition of lipoprotein thrombi in glomerular capillaries. The disease is characterized by proteinuria, progressive renal failure, and characteristic lipoprotein thrombosis in glomerular capillaries. Rare...

description | RATIONALE: Lipoprotein glomerulopathy (LPG) is a rare glomerular disease characterized by the deposition of lipoprotein thrombi in glomerular capillaries. The disease is characterized by proteinuria, progressive renal failure, and characteristic lipoprotein thrombosis in glomerular capillaries. Rare mutations in the apolipoprotein E (APOE) gene mainly contribute to disease pathogenesis. PATIENT CONCERNS: A 28-year-old man presented with severe proteinuria and hyperlipidemia. The patient was treated with a full dose of prednisone for 2 months and then combined with leflunomide 20 mg daily for 20 days; however, his edema continued to worsen. DIAGNOSIS: The patient was diagnosed LPG by laboratory examination and renal biopsy. INTERVENTIONS: The patient was treated with atorvastatin (20 mg) combined with irbesartan (75 mg) once a day. OUTCOMES: The patient's lipidaemia and proteinuria were significantly reduced. Genetic testing showed that the patient carried compound heterozygous mutations in APOE. The APOE gene was inherited from her mother and father. Parents with a heterogeneous mutation had normal kidney function without proteinuria. LESSONS: Usually, a single mutation in APOE can lead to the pathogenesis of LPG. This case shows that LPG could result from compound heterogeneous mutations of the APOE gene inherited from his mother and father. Intensive lipid-lowering combined with RASIs is effective in patients with LPG. Early renal biopsy and genetic mutation detection can avoid the unnecessary use of glucocorticoids and immunosuppressants. |
