Successful management of pemphigus foliaceus with mycophenolate mofetil as a steroid-sparing agent in a cat with corticosteroid-associated congestive heart failure

To the best of the authors' knowledge, this is the first case report to describe the use of MMF in a cat with PF. MMF was well tolerated and it was able to manage clinical signs even after the discontinuation of corticosteroids. Since mild and reversible haematological abnormalities were observed, careful monitoring during MMF administration is recommended. In this case, MMF dose reductions led to flares requiring a temporary reintroduction of corticosteroids to maintain disease control. MMF could be useful as an alternative treatment in cats affected by comorbidities where corticosteroid monotherapy would pose risks.
