Abstract: | Over a 5-year period, lymphocytic/plasmacytic gastroenteritis was diagnosed in 14 cats. Purebred cats were affected significantly (P less than 0.025) more often than nonpurebred cats. Mean age at onset of clinical signs was 6.8 years (range, 1 to 13 years); 11 cats were male. Vomiting and weight loss, each reported in 10 of 14 cats, were the most common clinical signs. Diarrhea was reported in 7 of 14 cats. Alopecia was found in 4 of 14 cats. High hepatic enzyme activities and low plasma protein concentrations were frequent biochemical findings. Hyperemia, hemorrhage, and a roughened or "cobblestone" mucosa were visualized by endoscopy in only 2 of 8 cats with duodenal disease and in 2 of 5 cats with gastric disease. Lymphocytic/plasmacytic inflammation was detected in biopsy specimens from the stomach or duodenum or both in all cats; the duodenum was affected most commonly. Degree of inflammation frequently varied among gastric, duodenal, and colonic specimens from the same cat. Glucocorticoid treatment and dietary management adequately controlled clinical signs in 7 cats, but treatment was ineffective in 6 cats, 5 of which were euthanatized because of severity of clinical signs. |
