2016 ACVIM Forum Research Abstract Program

thyroids of any of 12 dogs with GBM undergoing autopsy. These results identify a high prevalence of occult, often severe, decreases in individual serum thyroid hormone concentrations in GBM dogs. Influence of non-thyroidal illness must be considered for some of these abnormalities. Lack of serum TGAA and absent histologic inflammation in thyroids of GBM dogs is noteworthy. These findings suggest that an alternative mechanism for abnormal thyroid function in dogs with GBM should be considered. Hepatic fibrosis is an important complication of canine chronic hepatitis. To the authors' knowledge, the interobserver agreement associated with the histological scoring of fibrosis from canine hepatic biopsy specimens has not previously been reported. Therefore, the aim of this study was to evaluate the interobserver agreement for the histological scoring of canine hepatic fibrosis.
