Potential Treatment for FIP

Legendre, A.M. and J.W. Bartges, Effect of polyprenyl immunostimulant on the survival times of three cats with the dry form of feline infectious peritonitis. Journal of Feline Medicine & Surgery, 2009. 11(8): p. 624-626.

Feline infectious peritonitis (FIP) is a baffling and clinical important disease of cats caused by a virulent biotype of feline coronavirus. Despite the fact that the disease is relatively common, veterinarians are faced with a frustrating dilemma because there are no individual tests that are reliable for the diagnosis of FIP, the clinical picture is highly variable, and there is no known effective treatment. Polyprenyl immunostimulant (PI) is an investigational veterinary biologic manufactured by Sass & Sass, Inc and is comprised of a mixture of phosphorylated, linear polyisoprenols. This case series from the University of Tennessee describes three cats with the dry (non-effusive) form of FIP treated with PI. The cats were treated with varying doses of the drug, and by both subcutaneous and oral routes. Two of the three cats were still on treatment and were alive and well 2 years after diagnosis. The third cat survived 14 months but was treated for only 4.5 months. The investigators conclude that further studies to assess the therapeutic efficacy of PI for the treatment of FIP are warranted.
