Early diagnosis of AL amyloidosis and appreciation of the nutritional and coagulation abnormalities associated with liver and gastrointestinal involvement are critically important in the treatment and management. In cases of severe malabsorption total parenteral nutrition can be extremely helpful as a bridge to organ improvement. Rarely the use of antifibrinolytic agents such as oral aminocaproic acid with transfusion support may control severe bleeding in patients with coagulation abnormalities. It is important to keep in mind that organ improvement should follow in lag phase after the reduction in the pathologic free light chain with treatment. Closely following light chain levels may permit brief holidays from treatment and enable periods of recovery before resuming therapy in patients with prompt early and deep hematologic responses.
