This classification aids in guiding the diagnostic and therapeutic approach, enabling healthcare professionals to make informed decisions.
Pathophysiology and Mechanism of Disease
The pathophysiology of amyloidosis involves protein misfolding and aggregation. Normally soluble proteins become insoluble and form fibrils which deposit in tissues. This leads to a cascade of pathological changes, including inflammation, cell death, and subsequent organ dysfunction.
The process is often triggered by underlying conditions, like chronic inflammatory diseases or genetic mutations. For instance, in AL amyloidosis, the aberrant plasma cells produce excess light chains that misfold. Understanding this mechanism is critical for therapeutic development aimed at preventing or reversing these changes.
Prevalence and Epidemiology
Amyloidosis is considered rare, with an estimated annual incidence of 8-12 cases per million people for AL amyloidosis. The prevalence varies geographically and is influenced by factors such as age and underlying conditions. The median age for diagnosis is often in the 60s, indicating that older adults are more affected.
Research shows that certain populations, such as those with chronic inflammatory conditions, may have a higher incidence of AA amyloidosis. Understanding the epidemiology of amyloidosis aids in raising awareness and prompts further research to better understand why some groups are more at risk.
