Poliartrite imunomediada em decorrência de hemoparitose

Abstract

Immune-mediated non-erosive polyarthritis is a pathology that has as its etiology chronic infectious diseases, systemic lupus erythematosus, lymphocytic-plasmacytic synovitis, reactions to drugs or other mediated immune disorders, being in most cases of idiopathic origin. Immunomediated polyarthritis is caused by the deposition of immune complexes in the synovium of the joints, which produces a hypersensitivity reaction, leading to an inflammatory process in the affected area. The purpose of this report is to describe a case of immune-mediated non-erosive polyarthritis caused by hemoparasitosis in a dog. A four-year-old poodle, weighing 9.8 kg, with a history of progressive weight loss, hyporexia, diarrhea and ixodidiosis was treated. On physical examination, intermittent claudication and painful tenderness were found in bilateral hip joints. Hemogram, coproparasitological, and radiographic examinations were requested. The treatment instituted was subcutaneous application of atropine sulfate and imidocarb hydrochloride (two doses with an interval of 15 days) and prescription of doxycycline, ranitidine, carprofen, fembendazole.
