The goal of this study was to investigate the correlation between perinuclear antineutrophilic cytoplasmic antibody (pANCA) and clinical scores before and after treatment in diarrheic dogs with food-responsive disease (FRD) or inflammatory bowel disease (IBD). pANCA serology was evaluated prospectively by indirect immunofluorescence in 65 dogs with signs of gastrointestinal disease, and if positive, pANCA antibody titers were determined. Thirty-nine dogs with FRD responded to a novel diet, and 26 dogs with IBD were treated with corticosteroids. The severity of clinical signs was scored by means of a canine IBD activity index (CIBDAI). At initial examination, a significantly (P = .002) higher percentage of dogs were pANCA-positive in the FRD group (62%) compared with the IBD group (23%). pANCA titers were significantly higher (P = .003) before treatment in the FRD group (median titer 100) compared with the IBD group (median titer 1). However, there was no difference in pANCA titers between the groups after respective treatments because dogs in the IBD group had a significant increase in pANCA titer after treatment. The CIBDAI score decreased significantly (P < .001) after treatment in both groups (74% moderate to severe in FRD dogs before versus 8% after treatment; 85% moderate to severe in IBD dogs before versus 32% after treatment). There was no correlation between pANCA status in FRD or IBD dogs before treatment and scores for CIBDAI, endoscopy, or histopathology before or after treatment, except for the endoscopic duodenal score in dogs with FRD after treatment (P = .03). A positive pANCA test before therapy may aid in the diagnosis of FRD.
