Research Communications of the 27(th) ECVIM-CA Congress: Intercontinental, Saint Julian's, Malta, 14th to 16th September 2017

Disclosures: No disclosures to report. (2004) (2005) (2006) (2007) (2008) (2009) (2010) (2011) (2012) (2013) (2014) (2015) (2016) diagnosed with idiopathic eosinophilic bronchitis (EB) or idiopathic eosinophilic bronchopneumopathy (EBP) were reviewed. Total response (TR) or partial response (PR) was resolution or improvement of clinical signs respectively. Remission or long-term remission was absence of respiratory signs following discontinuation of therapy for more than one or six months respectively. Relapse was reoccurrence of clinical signs during remission. The following subgroups were established: acute (<1 month of clinical signs) versus chronic (>1 month of clinical signs); EB1 (no radiographic changes or bronchial/peribronchial pattern) versus EBP1 (interstitial/alveolar patterns); EB2 (no radiographic changes) versus EBP2 (any pulmonary pattern); prednisolone dose (≤ = 1 mg/kg/day; antiinflammatory-A-vs. >1 mg/kg/day; immunomediated-I-). These groups were compared for achievement of remission and long-term remission with chisquare or Fisher's exact test. Probability of achieving remission and long-term remission was evaluated by Kaplan Meier curves/ long rank test.
