Cat Feline Immune Complex Disease

Immune complex disease in cats causes systemic inflammation affecting multiple organs - targeted immunosuppression restores welfare.

Key Facts

Immune complex deposition causes vasculitis, glomerulonephritis, and polyarthritis in cats
Underlying infections, neoplasia, or primary immune dysregulation trigger immune complex formation
Identifying and treating the underlying trigger is the most effective management strategy
Prednisolone reduces immune complex-mediated inflammation when trigger management is insufficient
Regular monitoring of kidney function is essential as glomerulonephritis can progress silently

Welfare Considerations

Immune complex disease causes widespread, often painful inflammation across multiple body systems. Identifying and removing the underlying trigger, combined with appropriate immunosuppression, provides the most effective welfare restoration for affected cats.

What You Can Do

Investigate for underlying causes including chronic infections before initiating immunosuppression
Monitor kidney function regularly in cats with immune complex disease
Seek specialist internal medicine assessment for complex multi-organ immune disease
