Amyloid light-chain nephropathy

Last edited: 4/15/2026

Overview

Amyloid light-chain nephropathy (ALN) is characterized by the deposition of immunoglobulin light chains in the glomerular mesangium and capillary walls, leading to structural alterations such as glomerular capillary aneurysms and nodular glomerulopathy 1.

Diagnosis

  • Key Diagnostic Criteria: Light-chain deposition in mesangial and capillary walls, presence of glomerular capillary aneurysms, and nodular glomerulosclerosis 1.
  • Recommended Tests: Renal biopsy with electron microscopy to identify light-chain deposits and structural changes 1.
  • Grading: Histopathological grading based on the extent of light-chain deposition and severity of glomerular damage 1.

    • Management

  • First-Line Treatments: Targeted therapy to reduce light-chain production, such as plasma cell-directed treatments (e.g., bortezomib) 1.
  • Adjunctive Treatments: Supportive care including management of renal complications and hypertension control 1.
  • Specific Drug Classes: No specific doses mentioned; focus on underlying plasma cell dyscrasia management 1.

    • Special Populations

  • Pregnancy: Limited data; management should focus on controlling underlying plasma cell disorder and monitoring renal function 1.
  • Pediatrics: Not specifically addressed in the provided abstracts 1.
  • Elderly: Consideration of comorbidities and renal function when selecting treatment modalities 1.
  • Comorbidities: Management of associated plasma cell disorders and cardiovascular complications is crucial 1.

    • Key Recommendations

  • Renal biopsy with electron microscopy is essential for diagnosing ALN and identifying characteristic light-chain deposits and aneurysms 1 (Evidence: Strong).
  • Treatment should primarily target the underlying plasma cell dyscrasia to reduce light-chain production 1 (Evidence: Moderate).
  • Close monitoring of renal function and management of complications such as hypertension are critical in ALN patients 1 (Evidence: Moderate).
