Intestinal amyloidosis: Clinical manifestations and diagnostic challenge

Abstract: Amyloidosis is a heterogeneous group of diseases in which the extracellular deposition of abnormal fibrillar proteins disrupts tissue structure and function. Intestinal involvement is a very rare manifestation of amyloidosis compared to the most affected organs, the heart and kidneys. Damage of the gastrointestinal tract may be the only manifestation of amyloidosis, or -more often -is a component of the involvement of several organs in systemic amyloidosis. Any part of the digestive tract can be involved; howe… Show more

“…El término amiloidosis corresponde a un grupo heterogéneo de enfermedades infiltrativas caracterizadas por el depósito extracelular de fibrillas proteicas insolubles, lo que determina alteraciones en la estructura y función de los tejidos involucrados. [1][2][3] El tubo digestivo puede afectarse en cualquier sector de forma directa o por infiltración del sistema nervioso autónomo. 4,5 Los sectores más frecuentemente involucrados son el colon descendente y el sigmoides.…”

“…Habitual drinking of alcoholic beverages and possible chronic pancreatitis are risk factors for malabsorption‐related diarrhea 10 . Furthermore, a history of chronic inflammatory diseases, such as tuberculosis or rheumatoid arthritis, suggests the possible presence of gastrointestinal amyloidosis and related diarrhea 11 . Also, one‐third of patients with amyloid A amyloidosis are reported to have intractable diarrhea 12 …”
