SLE in the cat: Clinical signs vary dramatically


Cases resembling SLE have been previously reported in cats. Scott described two cats with low ANA titers and skin histology that was supportive of bullous SLE. Both cats achieved clinical remission with high dosages of glucocorticoids. Pedersen and Barlough described 11 cats with clinicopathological findings resembling SLE.

The majority of these cats (eight of 11) responded well to immunosupression. Two of those cats diagnosed with SLE fulfilled four of 11 criteria established by the ARA, including positive ANA, but supportive skin disease was absent. It is interesting to note that in the aforementioned study, the majority of cats diagnosed with SLE were purebred Siamese, Persians or Persian-related breeds.

This article serves to underscore how variable lupus erythematosus may present clinically in the pet, and even though this disease is rare, it is a reasonable differential diagnosis in the cat with symmetrical, non-pruritic dermatitis and cytopenia.
