The epidemiology of AL and AA amyloidosis.
The limited available epidemiological information on AL amyloidosis suggests that there may be differences between population-based studies and case series data with respect to variables such as age and racial patterns. Much more work in this area is required before specific aetiologic hypotheses can be tested. Most available data to approximate the epidemiology of AA amyloidosis are derived from autopsies. Most patients with AA amyloidosis die from causes other than amyloidosis, therefore mortality data based on death certificates is of limited value in AA amyloidosis. Case ascertainment in autopsy studies may be difficult due to the frequent lack of adequate histological controls. Establishment of registries for both AL and AA amyloidosis would facilitate epidemiological research in these disorders.
