PERITONITE INFECCIOSA FELINA: RELATO DE CASO

Feline Infectious Peritonitis (FIP) is a fatal feline disease caused by an enteric coronavirus, characterized by vasculitis and fibrinous serositis. The disease can be effusive or wet, characterized by fluid accumulation in the thoracic/abdominal cavity, or non-effusive (dry), without effusion. The diagnosis of FIP is made through the evaluation of history, clinical findings, laboratory results, and exclusion of similar diseases. A definitive diagnosis is made through necropsy and histopathology. This publication aims to report the occurrence and treatment of FIP using GS-441524 in a 7-month-old male, neutered, mixed breed cat weighing 2.750 kg, presenting with anorexia, inappetence, lethargy, weight loss, fever of 40.1°C, diarrhea, jaundice, distended abdomen without the presence of fluid in the abdominal cavity (as confirmed by ultrasound), and uveitis in the left eyeball. Both clinical signs and laboratory test results were consistent with the disease. Recent studies have shown promising results in the use of the molecule GS-441524 for the treatment of FIP. Thus, the animal underwent a 12-week treatment with the medication, showing significant improvement in the condition and no recurrence to date.
