Background. Renal amyloidosis is associated with a variety of underlying disease
processes. Although amyloid is identical in appearance in these diseases, the precursor …

Context.—Amyloidosis represents a group of diseases with extracellular deposition of
congophilic fibrils of similar morphology but differing chemical composition. The types …

We aimed to reassess renal amyloidosis in kidney biopsies with a focus on possibly
misclassified or unclassified cases and changes in the prevalence of different amyloid types …

Renal amyloid involvement results, especially, from AL (primary) or AA (secondary)
amyloidosis. The extent of amyloid tissue deposits in the kidneys and the clinical course of …

AL amyloidosis (light chain; previously also called primary amyloidosis) is a systemic
disease characterized by an amyloid deposition process affecting many organs, and which …

Renal amyloidosis is characterized by acellular Congo red positive deposits in the
glomeruli, interstitium and/or arteries. Light chain restriction on immunofluorescence studies …

Context.—A disease associated with amyloid deposits, called amyloidosis, is associated
with characteristic electron microscopic appearance, typical x-ray pattern, and specific …

Background. Renal amyloidosis results from protein misfolding and leads to progressive
renal insufficiency. Few data are available concerning the relevance of the …

Results The type of amyloid was Ig amyloidosis in 407 patients (85.9%), AA amyloidosis in
33 (7.0%), leukocyte chemotactic factor 2 amyloidosis in 13 (2.7%), fibrinogen A α chain …

Renal amyloidosis is not a frequent disease: its annual frequency is∼ 2.5–2.8% of all renal
biopsies. Individual cases are normally rare and for this reason clinical findings and …
