چکیده
Amyloidosis, a heterogenous group of disorders, is characterized by the extracellular deposition autologous, insoluble, fibrillar misfolded proteins. These proteins deposit in tissues aggregated s-pleated sheets arranged an antiparallel fashion and cause distortion to tissue architecture function. In current literature, about 60 heterogeneous amyloidogenic have been identified, out which 27 associated with human disease. Classified as rare disease, amyloidosis known wide range possible etiologies clinical manifestations.

Gastrointestinal Amyloidosis: Review of the Literature
Gastrointestinal amyloidosis (GIA), a protein deposition disorder, represents a complex common pathway that encompasses multiple etiologies and presentations. It represents a significant diagnostic and treatment challenge. The disease results from the deposition of insoluble extracellular protein fragments that have been rendered resistant to digestion. GIA can be acquired or genetic, and most ...
متن کاملGastrointestinal amyloidosis: a case of chronic diarrhoea.
Amyloidosis is a rare disease caused by extracellular deposits of insoluble fibrillar proteins in various organs and tissues. There are different forms of amyloidosis distinguished by the type of protein fibrils, by the sites of deposition and by associated conditions. Gastrointestinal involvement is common both in primary and secondary amyloidosis, while isolated gastrointestinal amyloidosis i...
متن کاملClinical management of gastrointestinal amyloidosis
Amyloidosis is characterized by extracellular deposition of abnormal protein, consisting of primary, secondary, hemodialysis-related, hereditary, senile and localized type. Primary amyloidosis is associated with monoclonal light chains. Secondary amyloidosis is associated with inflammatory, infectious, and neoplastic diseases. Amyloid deposition in the gastrointestinal tract can manifest the sy...
متن کاملGastrointestinal amyloidosis complicating psoriatic arthropathy.
A patient is described who developed gastrointestinal amyloidosis complicating psoriatic arthropathy. The presenting symptom was progressive dysphagia due to oesophageal involvement. Other clinical features included gastric ulceration with melaena, intestinal pseudo-obstruction and evidence of impaired renal function. The oesophageal symptoms improved after endoscopic dilatation of the cardia. ...
