Disease burden of systemic light-chain amyloidosis: a systematic literature review
Introduction
A systematic literature review on systemic light chain (AL) amyloidosis was conducted in order to understand the disease burden, and identify unmet medical needs and knowledge gaps.
Methods
MEDLINE, Embase and Cochrane databases were searched for English language studies published in the last 10 years using search terms that focused on the clinical, economic, and patient-reported outcome (PRO) aspects of AL amyloidosis. There was a low yield of articles in the economic and PRO categories and additional searches were conducted in clinical conference proceedings, and using Google and Google Scholar. After review, there were 65 articles included for data extraction.
Results
AL amyloidosis is a rare disorder without any FDA or EMA approved indications for drug therapy. Using off-label therapies, there is a high rate, 42-64%, of non-response or progression, and an associated high mortality. Toxicities during therapy are common with estimates of up to 30-40% of patients experiencing severity of grade 3 or higher. Patients with AL amyloidosis report severe psychological distress, anxiety and clinical depression.
Conclusions
There is a deficiency in the literature on the economic costs associated with AL amyloidosis, and information on costs has been derived from studies that examined multiple myeloma or other disease or treatment components common to AL amyloidosis.
