Rare, Yet Emerging Cause of Graft Dysfunction-ALECT 2 Amyloidosis

Abstract

Amyloidosis is characterized by pathological deposition of abnormal protein aggregates in various tissues, AL protein being the commonest. Amyloidosis derived from leukocyte cell-derived chemotaxin 2 (LECT2) is a recently recognized form of amyloidosis in the United States with predominant involvement of kidney and liver. We present a case of ALECT2 renal amyloid in a transplant recipient who presented with gradual worsening of graft function and subnephrotic proteinuria. To our knowledge, this is first case of LECT2 amyloidosis from Northern India in a transplant recipient. There is no effective therapy for amyloidosis derived from leukocyte cell-derived chemotaxin 2.

Keywords: ALECT2 amyloid; graft dysfunction; renal transplant.
