Summary
L’Inflammatory Bowel Disease (IBD) è una patologia gastroenterica cronica che può colpire cani di tutte le età; la diagnosi di tale malattia prevede la conferma istopatologica dell’infiammazione intestinale e la necessità di terapia immunomodulante. Lo scopo dello studio è quello di analizzare l’eritrogramma e il piastrinogramma di cani con IBD per valutare il potenziale significato clinico di anemia, conta piastrinica, Mean Platelet Volume (MPV) e Platelet-to-Lymphocyte ratio (PLR). Sono stati arruolati 41 cani con diagnosi di IBD. La presenza di anemia è stata evidenziata nel 17% dei casi ed è risultata significativamente associata al Canine IBD activity index (CIBDAI, p=0,0020), al Canine Chronic Enteropathy Clinical Activity index (CCECAI, p=0,0004) e alla presenza di protein-losing Enteropathy (PLE, p=0,0436). Trombocitosi e trombocitopenia sono state riscontrate rispettivamente nel 22% e nel 12,2% dei casi; sono state evidenziate associazioni significative tra conta piastrinica e CIBDAI (p=0,0145), MPV (p=0,0010) e presenza di PLE (p=0,0084). La riduzione dell’MPV è stata trovata nel 17,5% dei pazienti. Tale parametro è risultato associato al CIBDAI (p=0,0079), al CCECAI (p=0,0009), agli score endoscopici di stomaco (p=0,0034) e duodeno (p=0,0328), allo score istologico dello stomaco (p=0,0299), alla CRP (p=0,0207), alla presenza di PLE (p=0,0232) e al PLR (p=0,0038). Inoltre, il PLR è risultato associato all’indice CCECAI (p=0,0050), alla concentrazione di Albumina (p=0,0297), all’HCT (p=0,0117) e al RBC (p=0,0035). Infine, PLE, PLT, MPV e PLR sono risultati significativamente associati al miglioramento dei pazienti. Dallo studio è emerso che questi ultimi parametri sembrano avere un importante significato clinico, in quanto associati alla prognosi della malattia.

Inflammatory Bowel Disease (IBD) is a chronic gastrointestinal disorder affecting dogs of all ages. The diagnosis of IBD is based on histological features of intestinal inflammation associated with the necessity of immune-modulating therapy. The aim of the study was to evaluate erythrocytes and platelets modifications to determine the clinical role of anemia, platelet count, mean platelet volume (MPV) and Platelet-to-lymphocyte ratio (PLR) in dogs with IBD. Anemia was present in 17% of dogs and it was statistically associated with Canine IBD activity index (CIBDAI, p=0,0020), Canine Chronic Enteropathy Clinical Activity index (CCECAI, p=0,0004) and with presence of protein-losing enteropathy (PLE, p=0,0436). Thrombocytosis and thrombocytopenia were present in 22% and 12,2% of dogs, respectively. We found a significant association between platelet count and CIBDAI (p=0,0145), MPV (p=0,0010) and presence of PLE (p=0,0084). Lower MPV values were identified in 17,5% of IBD dogs. This parameter was statistically associated with CIBDAI (p=0,0079), CCECAI (p=0,0009), endoscopic score of stomach (p=0,0034) and duodenum (p=0,0328), histological score of stomach (p=0,0299), CRP (p=0,0207), presence of PLE (p=0,0232) and PLR (p=0,0038). In addition, PLR was significantly associated with CCECAI (p=0,0050), serum albumin concentration (p=0,0297), HCT (p=0,0117) and RBC (p=0,0035). Lastly, PLE, PLT, MPV and PLR was associated with clinical improvement of patients. These last parameters seem to have an important clinical relevance, as they are associated with the outcome of IBD.
