Cat Feline Immune-Mediated Disease

Immune-mediated diseases in cats including IMHA and immune thrombocytopenia require aggressive treatment and careful monitoring for good welfare outcomes.

Key Facts

Feline immune-mediated haemolytic anaemia (IMHA) is less common than canine IMHA but similarly serious
Prednisolone is first-line immunosuppression for most feline immune-mediated conditions
Doxycycline is added empirically to cover occult haemotropic mycoplasma infections
Blood transfusion provides critical stabilisation while immunosuppression takes effect
Monitoring packed cell volume (PCV) during treatment guides dose adjustment

Welfare Considerations

Immune-mediated diseases cause acute and severe welfare compromise through haemolysis and immune activation. Aggressive initial treatment combined with appropriate monitoring and dose adjustment gives individual cats the best chance of full recovery.

What You Can Do

Seek immediate emergency veterinary care for cats with pale gums or extreme lethargy
Understand that immune-mediated diseases require intensive treatment and monitoring
Discuss long-term prognosis and monitoring requirements with your vet during treatment
