Immune‐based non‐erosive inflammatory joint disease of the dog. 1. Canine systemic lupus erythematosus

Abstract

ABSTRACT The features of 13 dogs with systemic lupus erythematosus (SLE) are described. Canine SLE is a multisystemic disease characterized by autoimmunity and immune complex hypersensitivity. The presence of antinuclear antibody in the blood is an important diagnostic feature. All 13 cases had a non‐erosive symmetrical polyarthritis. Autoimmune haemolytic anaemia was seen in five cases, thrombocytopenia in three, skin lesions in four; neurological involvement in one; and gastrointestinal signs in one. Treatment was with cytotoxic drugs(cyclophosphamide initially) and prednisolone.
