Colitis linfoplasmocitaria canina en paciente de raza pastor Alemán. Reporte de caso.

Abstract

Canine lymphocytic/ plasmocytic colitis is called this way because it is a process that groups the diseases called: chronic idiopathic colitis or inflammatory bowel disease. These diseases include chronic processes in the animal where cellular infiltration is generated in the mucosa of the colon by inflammatory cells: lymphocytes, plasma cells, eosinophils or neutrophils. Patients who presented this type of condition, had symptoms such as: chronic diarrhea, which has not been able to be diagnosed with conventional methods, and did not matched with other common causes like parasitic or infectious processes, neoplasms or allergies. Since the exact etiological cause of this disease is really unknown, it could be said that it is a multifactorial disease, which could be related to genetic, dietary, allergic, bacterial or stress factors. Furthermore, genetic predisposition of German Shepard breed is very important. This is one of the breeds that has this condition more often. They are usually patients treated with dietary, anti parasitic and antibiotic therapies or with anti-inflammatory drugs, without optimal response. Specifically in this clinical case, a 5-year-old German Shepard patient with history of chronic diarrhea since he was approximately 8 months old. The patient was treated for various causes, but relapsed multiple times until he was given a treatment at the Animal Protective Clinic. In this place, basic exams were performed: hematic and coproscopic. Also,

he was given in-hospital management and had more specific tests: cyanocobalamin, trypsin and folic acid. In order to rule out other alterations such as: malabsorption syndrome and exocrine pancreatic insufficiency, as differential diagnoses. As a last diagnostic method, a colonoscopy was performed with samples sent for biopsy, which leads to the definitive diagnosis.
