Renal AA amyloidosis secondary to morbid obesity?

Author information

Hospital Universitari Arnau de Vilanova, Lleida, Spain.


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.
