Clinical characteristics of dogs presenting with vomiting as a gastrointestinal sign of chronic enteropathy. Vet Anim Sci 2022; 17:100255. [PMID: 35769538 PMCID: PMC9234693 DOI: 10.1016/j.vas.2022.100255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 06/08/2022] [Accepted: 06/09/2022] [Indexed: 11/30/2022] Open
Abstract
Some dogs with chronic enteropathy (CE) presented with vomiting without diarrhea. Vomiting was significantly associated with food-responsive enteropathy. Vomiting was significantly associated with higher duodenal eosinophil scores. The survival time was the longest in the vomiting group among dogs with CE.
Vomiting is a major gastrointestinal (GI) sign of chronic enteropathy (CE) in dogs. Previous studies have reported clinical characteristics of dogs with CE, who developed diarrhea with or without vomiting as GI signs. However, to characterize clinical features of dogs with CE appropriately, dogs presenting with vomiting without diarrhea should be included in the analysis. Thus, this study aimed to characterize clinical features and outcomes of dogs that presented with vomiting without diarrhea. Based on their presenting GI signs, we retrospectively classified 66 dogs with CE into “Vomiting”, “Diarrhea”, or “Vomiting and diarrhea” groups and compared clinical and histological characteristics of each group. We found that 18 of the 66 dogs with CE (27%) presented with vomiting without diarrhea as a GI sign. Compared to the other 2 groups, the Vomiting group was significantly associated with food-responsive enteropathy (FRE), Beagle, lower clinical severity scores, higher plasma albumin levels, and higher histological scores for eosinophils in the duodenal lamina propria according to the univariate analysis. The multivariate analysis revealed that FRE and higher histological scores for eosinophils in the duodenal lamina propria were significant variables in the Vomiting group. Moreover, the survival time was the longest in the Vomiting group among dogs with CE. These findings are of clinical significance as they indicate that presenting with vomiting without diarrhea may not only be helpful in differentiating FRE from the other types of CE, but also in predicting the prognosis.

Evaluation of Prognostic Factors, including Duodenal P-Glycoprotein Expression, in Canine Chronic Enteropathy. Animals (Basel) 2021; 11:ani11082315. [PMID: 34438774 PMCID: PMC8388466 DOI: 10.3390/ani11082315] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 07/29/2021] [Accepted: 08/01/2021] [Indexed: 01/20/2023] Open
Abstract
The aim of this retrospective single-center study was to evaluate which factors, including expression of P-glycoprotein (P-gp), a membrane-bound protein involved in multiple drug resistance, could predict the response to treatment in canine immunosuppressant-responsive enteropathy (IRE). Dogs with IRE or non-responsive enteropathy (NRE) that were examined from 2005 to 2014 were included and were divided into two groups (IRE vs. NRE). Signalment, history, and clinical and laboratory findings were collected. P-glycoprotein immunohistochemistry was carried out on duodenal biopsies of both groups stored in our biobank, and immunophenotyping and molecular clonality were performed on the NRE samples. Ninety-two dogs were enrolled, 73 IRE (79.3%) and 19 NRE (20.7%), with a prevalence of pure breed (78.3% vs. 21.7%) and male dogs (p < 0.001). Factors associated with a worse prognosis were previous treatment with steroids (p = 0.033) and lower serum total protein concentration (p = 0.005). Clonality testing on the NRE duodenal biopsies showed 5/16 clonal responses, assuming a latent undiagnosed lymphoma as a possible cause of the NRE.

Abstract
Canine chronic enteropathy (CE) is a group of immunogenetic disorders of unclear etiology characterized by chronic or recurrent gastrointestinal signs and inflammation. Diagnosis of CE subtypes by treatment response is a lengthy and challenging process, particularly in refractory cases of the disease. Given known association of dog leukocyte antigen (DLA) class II genotype and various immunogenetic disorders between and across breeds, this study was designed to examine the potential of determining susceptibility to refractory CE through identification of risk and protective genotypes in French bulldogs and miniature dachshunds-two popular dog breeds in Japan. Sequence-based genotyping of three DLA class II genes in 29 French bulldogs and 30 miniature dachshunds with refractory CE revealed a protective haplotype DLA-DRB1*002:01-DQA1*009:01-DQB1*001:01 against CE in French bulldogs (OR 0.09, 95 % CI 0.01-0.71, p = 0.0084). No statistical difference was noted between miniature dachshund cases and controls. These findings, largely disparate from a previous study on German shepherd dogs in the UK, were taken as possible indication of etiological differences in the refractory CE noted between and within breeds, and by extension, the potential of identifying such disease heterogeneity by DLA typing. The DLA-DQA1/DQB1 haplotype, protective against CE in our French bulldogs, has been reported as protective in various immune-mediated disorders such as Doberman hepatitis (Dyggve et al., 2011). Likewise, the DLA-DRB1*006:01 risk allele for Doberman hepatitis was noted in more French bulldogs with CE compared to controls, in line with reports on genotypes associated with both risk and protection being shared across various autoimmune diseases and breeds. These findings support an immunogenetic basis to the French bulldog-CE in our analysis, calling for further DLA studies working with larger samples and different breeds towards phenotypic clarification that may aid in early diagnosis, treatment, and prophylaxis through epigenetic approaches and breeding.

Abstract
A 7-year 6-month-old, castrated male Shiba dog presented with a 1-month history of
lethargy, anorexia, vomiting, and frequent watery diarrhea. Weight loss, hypoalbuminemia,
anemia, and leukocytosis were detected at the first visit. The dog was diagnosed with
non-responsive enteropathy (NRE) based on clinical and histopathological examinations.
Since the dog did not respond to the immunosuppressive drugs, fecal microbiota
transplantation (FMT) was performed during the treatment with chlorambucil. A single
endoscopic FMT into the cecum and colon drastically recovered clinical signs and
clinicopathological abnormalities and corrected dysbiosis in the dog. No recurrence or
adverse events were observed. The present case report suggests that FMT, possibly together
with chlorambucil, might be a treatment option for NRE in Shiba dogs that have poorer
prognosis compared with other dog breeds.

Abstract
The increasing incidence of gastrointestinal tract pathologies in dogs and the worrisome topic of antibiotic resistance have raised the need to look for new therapeutic frontiers. Of these, the use of probiotics represents a potential therapeutic alternative. Lactobacillus kefiri (Lk) is a species of Lactobacillus isolated from kefir. Previous studies have demonstrated that its administration in mice downregulates the expression of proinflammatory mediators and increases anti-inflammatory molecules in the gut immune system. It also regulates intestinal homeostasis, incrementing immunoglobulin A (IgA) secretion. Since Lk has never been studied as a single probiotic in dogs, the aim of this study was to evaluate the safety of Lk in dogs, and its effect on IgA secretion and on intestinal microbiota composition. Ten healthy dogs without a history of gastrointestinal diseases were included. The dogs received Lk at a dose of 107 live microorganisms orally, once daily for 30 days. The fecal samples were tested before administration, in the middle, at the end, and 30 days after discontinuation. The IgA secretion concentration and the microbiota composition were evaluated on the fecal samples. The results in this study suggested that Lk did not influence the concentration of IgA, nor significant changes of the intestinal microbiota were observed during and after the treatment. Therefore, additional studies are needed to investigate if a higher daily dosage of Lk can influence the intestinal homeostasis of dogs.

Abstract
Shiba dogs are predisposed to chronic enteropathy (CE) and have poorer prognosis than other dog breeds. The objective of this study was to investigate the significance of polymerase chain reaction for antigen receptor
rearrangement (PARR) results on clinical findings and prognosis of Shiba dogs with CE. We retrospectively collected data on 22 Shiba dogs diagnosed as having CE. Fifty-nine percent of the dogs had clonality-positive results on
PARR analysis. Furthermore, on histopathology, epitheliotropic behavior of small lymphocytes of the intestinal mucosa was observed significantly more frequently in dogs with clonal rearrangement of antigen receptor genes
(P=0.027). The median overall survival time of clonality-positive dogs was 48 days (range, 4–239 days), compared to 271 days (range, 45–1,316+ days) in clonality-negative dogs. The median overall survival time
of epitheliotropism-positive dogs was 76 days (range, 30–349 days) compared to 239 days (range, 4–1,316+ days) for epitheliotropism-negative dogs. Statistical analysis revealed that the clonality-positive result was associated
with significantly shorter survival time (P=0.036). In contrast, presence or absence of epitheliotropism had no statistically significant effect on survival time (P=0.223). These cases might
appropriately be diagnosed as small T-cell intestinal lymphoma; there are some common clinical and pathogenic features with human enteropathy-associated T-cell lymphoma type 2. The pathogenesis and poor prognosis for Shiba dogs
with CE seem to be associated with this type of lymphoma, although further investigation is warranted.

Abstract
Background Dogs with a chronic enteropathy (CE) have a lower vitamin D status, than do healthy dogs. Vitamin D status has been associated with a negative clinical outcome in humans with inflammatory bowel disease. Objectives To examine the relationship between serum 25 hydroxyvitamin D (25(OH)D) concentrations at diagnosis and clinical outcome in dogs with a CE. Animals Forty‐one dogs diagnosed with CE admitted to the Royal Dick School of Veterinary Studies, Hospital for Small Animals between 2007 and 2013. Methods Retrospective review. Serum 25(OH)D concentrations were compared between dogs which were alive at follow up or had died because of non‐CE‐related reasons (survivors) and dogs which died or were euthanized due to their CE (non‐survivors). A binary logistic regression analysis was performed to determine significant predictors of death in dogs with CE. Results Serum concentrations of 25(OH)D at the time a CE was diagnosed were significantly lower in nonsurvivors (n = 15) (median nonsurvivors 4.36 ng/mL, interquartile range 1.6–17.0 ng/mL), median survivors (n = 26) (24.9 ng/mL interquartile range 15.63–39.45 ng/mL, P < .001). Serum 25(OH)D concentration was a significant predictor of death in dogs with CE (odds ratio 1.08 [95% CI 1.02–1.18)]). Conclusions Serum 25(OH)D concentrations at diagnosis are predictive of outcome in dogs with CE. The role of vitamin D in the initiation and outcome of chronic enteropathies in dogs is deserving of further study.

Abstract
BACKGROUND Intestinal lymphangiectasia (IL), a type of protein-losing enteropathy (PLE), is a dilatation of lymphatic vessels within the gastrointestinal tract. Dietary fat restriction previously has been proposed as an effective treatment for dogs with PLE, but limited objective clinical data are available on the efficacy of this treatment. HYPOTHESIS/OBJECTIVES To investigate the clinical efficacy of dietary fat restriction in dogs with IL that were unresponsive to prednisolone treatment or showed relapse of clinical signs and hypoalbuminemia when the prednisolone dosage was decreased. ANIMALS Twenty-four dogs with IL. METHODS Retrospective study. Body weight, clinical activity score, and hematologic and biochemical variables were compared before and 1 and 2 months after treatment. Furthermore, the data were compared between the group fed only an ultra low-fat (ULF) diet and the group fed ULF and a low-fat (LF) diet. RESULTS Nineteen of 24 (79%) dogs responded satisfactorily to dietary fat restriction, and the prednisolone dosage could be decreased. Clinical activity score was significantly decreased after dietary treatment compared with before treatment. In addition, albumin (ALB), total protein (TP), and blood urea nitrogen (BUN) concentration were significantly increased after dietary fat restriction. At 2 months posttreatment, the ALB concentrations in the ULF group were significantly higher than that of the ULF + LF group. CONCLUSIONS AND CLINICAL IMPORTANCE Dietary fat restriction appears to be an effective treatment in dogs with IL that are unresponsive to prednisolone treatment or that have recurrent clinical signs and hypoalbuminemia when the dosage of prednisolone is decreased.
