Systemic amyloidosis from A (AA) to T (ATTR): a review.

Journal of internal medicine·2020

Amyloidosis diagnosis involves checking for monoclonal light chains in patients over 40 with specific symptoms. Early detection and understanding prognosis, especially cardiac involvement, are key for effective treatment.

Area of Science:

  • Nephrology
  • Cardiology
  • Neurology
  • Hematology

Background:

  • Amyloidosis is a systemic disease characterized by extracellular deposition of misfolded proteins.
  • It can affect multiple organs, leading to diverse clinical manifestations.

Observation:

  • Consider amyloidosis in patients >40 with nephrotic syndrome, non-ischemic congestive heart failure, idiopathic neuropathy, or hepatomegaly.
  • Diagnostic workup includes serum/urine immunoelectrophoresis and immunofixation to detect monoclonal light chains.

Findings:

  • Monoclonal light chains suggest amyloidosis, often confirmed by amyloid stains on bone marrow or fat aspirates.
  • Cardiac involvement is the primary prognostic indicator.

Implications:
