title: Renal AA amyloidosis secondary to morbid obesity?
abstract: Systemic amyloidosis is characterized by extracellular deposits on different organs of insoluble fibrils compounded of low molecular weight subunits coming from a great diversity of serum proteins. Secondary amyloidosis AA is due to fibril deposition composed of fragments of the acute phase reactant serum amyloid A. We report a case of a young patient with morbid obesity and hypertension who was admitted to our hospital for acute renal insufficiency associated with nephrotic range proteinuria which developed while on antibiotic treatment for a respiratory infection. AA Amyloidosis was diagnosed by renal biopsy. Based on recent evidence we hypothesize that morbid obesity could be the underlying cause of the deposit disease.
