Fecal Microbiota Transplantation (FMT) is a medical procedure involving the transfer of intestinal microbiota from a healthy donor into the gut of a diseased recipient, with the aim of treating a range of gastrointestinal disorders that are unresponsive to conventional therapies. The purpose of this thesis was to evaluate the effectiveness of FMT in a group of 143 dogs affected by chronic enteropathy refractory to standard treatments. Additionally, the study aimed to identify potential predictive factors of the transplant outcome in order to select candidates that are more likely to benefit from the treatment. First of all, patients underwent a single cycle of transplantation, which consisted of the daily intake of capsules over a 30-day period. From this premise, clinical response was assessed based on data collected through questionnaires completed by the attending veterinarians before and after treatment. Specifically, the following parameters were taken into account: CCECAI classification index, Body Condition Score, Fecal Score, level of clinical severity and main gastrointestinal symptoms. The results showed a significant improvement in all evaluated parameters following the transplant, with the exception of the Body Condition Score. Furthermore, some of these parameters and other factors, such as the age of the subjects and the time elapsed between the diagnosis of chronic enteropathy and the start of treatment, were analyzed in relation to treatment outcomes, defined using a qualitative scale based on the overall clinical condition of the subject at the end of treatment. However, the descriptive analysis did not highlight any notable association between the variables considered.
Il trapianto di microbiota fecale (FMT) è una procedura medica che prevede il trasferimento del microbiota intestinale da un donatore sano ad un ricevente malato, con l’obiettivo di trattare una serie di patologie gastrointestinali non responsive alle terapie convenzionali. Lo scopo della tesi è stato valutare l’efficacia del FMT in un gruppo di 143 cani affetti da enteropatia cronica refrattaria ai trattamenti standard. Inoltre, ci si è proposto di individuare eventuali fattori predittivi dell’esito del trapianto, al fine di riuscire a selezionare i candidati che con maggiore probabilità beneficeranno del trattamento. I pazienti sono stati sottoposti ad un singolo ciclo di trapianto che consiste nell’assunzione quotidiana di capsule per un periodo di 30 giorni. È stato possibile valutare la risposta clinica dei pazienti attraverso le informazioni raccolte nei questionari che i veterinari curanti hanno compilato pre e post trattamento. In particolare, sono stati presi in considerazione l’indice di classificazione CCECAI, il Body Condition Score, il Fecal Score, il livello di gravità clinica e altri sintomi principali. I risultati ottenuti hanno mostrato che a seguito del trapianto c’è stato un miglioramento significativo di tutti i parametri presi in considerazione, ad eccezione del Body Condition Score. Inoltre, alcuni di questi parametri e altri fattori, come l’età dei soggetti e il tempo trascorso dalla diagnosi di enteropatia cronica all’inizio del trattamento, sono stati analizzati in relazione all’esito del trattamento, definito con una scala qualitativa in base alle condizioni cliniche complessive del soggetto al termine del trapianto. Tuttavia, l’analisi descrittiva non ha evidenziato particolari associazioni tra le variabili prese in esame.
