The purpose of this study will be the search for a biomarker in the urine for AA amyloidosis in cats. This identification will allow to separate, in a non-invasive way, the sick cats from the healthy ones, allowing a therapeutic approach towards amyloidosis with the aim of improving animal welfare. The study chose urine as a substrate, as well as to be a simple and easily performed procedure, because as widely reported in the literature, the kidney is the main organ in which amyloidosis fibers are deposited. The following retrospective study was performed through the collection of histopathological samples, which allowed us to differentiate sick from healthy cats, and urine on which laboratory tests were performed: specific gravity, PU / CU, SAA / CU. Particular attention in this study was given to proteomic analysis, which with a biomarker discovery process will aim to find proteins necessary for the diagnosis of the disease.
La finalità di questo studio è la ricerca di un biomarker nelle urine per quanto riguarda l’amiloidosi AA nei gatti. Tale identificazione consentirà di separare, in maniera non invasiva, i gatti malati dai sani permettendo un approccio terapeutico verso l’amiloidosi con l’obbiettivo di migliorare il benessere animale. Lo studio ha scelto le urine come substrato, oltre che per essere una procedura semplice e facilmente eseguibile, perché come riportato ampiamente in letteratura il rene risulta essere il principale organo in cui si depositano le fibre dell’amiloidosi. Il seguente studio retrospettivo è stato eseguito tramite la raccolta di campioni istopatologici, che ci hanno permesso di differenziare i gatti malati dai sani, e di urine sulle quali sono stati eseguiti esami di laboratorio: peso specifico, PU/CU, SAA/CU. Particolare attenzione in questo studio è stata concessa all’analisi proteomica, che con un processo di biomarker discovery si porrà l’obbiettivo di trovare proteine necessarie alla diagnosi della malattia.

Abstract
The purpose of this study will be the search for a biomarker in the urine for AA amyloidosis in cats. This identification will allow to separate, in a non-invasive way, the sick cats from the healthy ones, allowing a therapeutic approach towards amyloidosis with the aim of improving animal welfare. The study chose urine as a substrate, as well as to be a simple and easily performed procedure, because as widely reported in the literature, the kidney is the main organ in which amyloidosis fibers are deposited. The following retrospective study was performed through the collection of histopathological samples, which allowed us to differentiate sick from healthy cats, and urine on which laboratory tests were performed: specific gravity, PU / CU, SAA / CU. Particular attention in this study was given to proteomic analysis, which with a biomarker discovery process will aim to find proteins necessary for the diagnosis of the disease.File | Dimensione | Formato | |
