New-onset cardiac amyloidosis while in remission from systemic AL amyloidosis

Abstract

In light chain amyloidosis, a reduction in dFLC to below 40 mg/l is a prerequisite for organ recovery as nearly half of the patients who achieve very good partial haematological responses have improvement in the function of the involved organ. We describe a patient who developed new-onset cardiac amyloidosis despite a post-treatment reduction in dFLC to <10 mg/l.
