    Abstract:
    Lymphocytic-plasmacytic enteritis (LPE) was diagnosed by intestinal biopsy in 24 dogs with chronic small intestinal diarrhea. Vomiting, weight loss, and reduced appetite were frequent. Breed predispositions were not documented, although four patients were German Shepherd dogs. Hypoproteinemia, hypoalbuminemia, and hypoglobulinemia were common and most likely a result of protein-losing enteropathy. Other biochemical abnormalities were uncommon. Intestinal malabsorption was common. Neutrophilia (sometimes with increased band neutrophils), monocytosis, lymphopenia, and eosinopenia were the most consistent hematologic abnormalities. The severity of the lymphocytic-plasmacytic infiltration was not significantly different (P greater than 0.05) between regions of small intestine. However, the severity of cellular infiltration often varied among different regions of small intestine in the same dog. Changes in villous architecture and lacteal dilation were common. Intestinal nematode infestation was diagnosed in five dogs, and pancreatic exocrine insufficiency was diagnosed in one dog. In the remaining 18 dogs, besides LPE, no other associated or concurrent intestinal disease was diagnosed.
