Use of modified ciclosporin in the management of feline pemphigus foliaceus: a retrospective analysis.

ABSTRACT

BACKGROUND: Glucocorticoids as sole therapy for pemphigus foliaceus (PF) in cats are not always successful, and it is common to need additional immunomodulating agents to manage the disease. HYPOTHESIS/OBJECTIVES: This retrospective study evaluated the use of modified ciclosporin as an adjuvant or sole immunomodulating drug in cats with PF and compared their response to PF cats managed with chlorambucil. ANIMALS Fifteen client-owned cats diagnosed with PF that received ciclosporin and/or chlorambucil as part of their treatment and had adequate follow-up to assess treatment response were evaluated. METHODS: Records were reviewed from feline PF patients presented between the years of 1999 and 2009. Cats were divided into two treatment groups those treated with ciclosporin and those treated with chlorambucil. Most cats in both groups also received concurrent systemic glucocorticoids. Each group contained six patients. Three cats were treated with both medications and are discussed separately. Time to disease remission, remission-inducing glucocorticoid dose, maintenance or final glucocorticoid dose, disease response and adverse effects were assessed. RESULTS: There was no significant difference in remission times or disease response between groups. All six patients maintained with ciclosporin for PF management were weaned off systemic glucocorticoids, while glucocorticoid therapy was stopped in only one of the six cats receiving chlorambucil. CONCLUSIONS AND CLINICAL IMPORTANCE Modified ciclosporin is effective in the management of feline pemphigus foliaceus and is glucocorticoid sparing.
