Abstract

OBJECTIVE

To report abdominal ultrasonography (AUS) findings in dogs with clinical signs of acute pancreatitis (AP) during the first 2 days of hospitalization and to compare AUS findings with severity of disease and mortality rate.

ANIMALS

37 client-owned dogs with clinical signs of AP.

PROCEDURES

Dogs suspected of having AP with complete medical records, AUS examinations performed throughout the first 2 days of hospitalization, and available frozen surplus serum samples for quantitative measurement of canine pancreatic lipase (cPL) concentrations at hospital admission met the criteria for study inclusion. Dogs were grouped as AUS+ or AUS− on the basis of positive or negative findings for AP on AUS, respectively. Abdominal ultra-sonography findings of AP were stratified (as mild, moderate, or severe) by use of an AUS severity index, and a canine acute pancreatitis severity score was calculated.

RESULTS

24 of 37 (64.8%) dogs had AUS findings of AP at hospital admission, whereas 10 had positive findings for AP on AUS within 2 days of hospitalization. Three (8%) dogs were AUS− but had serum cPL concentrations > 400 µg/L (ie, values considered diagnostic for AP). On the AUS severity index, 5 of 34 (14.7%) AUS+ dogs had mild findings, 18 (52.9%) AUS+ dogs had moderate findings, and 11 (32.4%) AUS+ dogs had severe findings. Severe findings were associated with a higher risk of death than mild and moderate findings. A significant association was found between canine acute pancreatitis severity scores and mortality rates.

CONCLUSIONS AND CLINICAL RELEVANCE

For dogs with clinical signs of AP, repeated AUS examinations during hospitalization should be performed, severe findings on the AUS severity index may indicate an increased risk of death, and serum cPL concentrations may increase earlier than findings on AUS of AP.

Abstract

OBJECTIVE

To prospectively evaluate the clinical and prognostic importance of duodenal endoscopic and histologic findings, including duodenal mucosal counts of forkhead box P3-positive regulatory T cells (Foxp3+ Tregs), in dogs with immunosuppressant-responsive enteropathy (IRE).

ANIMALS

57 client-owned dogs with IRE.

PROCEDURES

The canine chronic enteropathy clinical activity index (CCECAI) was used to assess each dog when IRE was diagnosed (T0) and 1, 3, 6, and 12 months later. Dogs were grouped on the basis of clinical response (responder group vs nonresponder group) and 12-month long-term outcome (responded to treatment and did not relapse [good outcome group] vs did not respond to treatment or had relapsed [bad outcome group]). At T0, dogs underwent gastrointestinal endoscopy and endoscopic biopsy, with results for variables of duodenal endoscopic and histologic evaluations scored and compared across groups.

RESULTS

At T0, the overall median CCECAI score was 7; CCECAI score was not associated with clinical response or relapse. Dogs had significantly greater odds of being in the bad outcome group (vs the good outcome group) if they had a histologic score of 3 (OR, 3.5; 95% CI, 1.09 to 11.3). No differences in the counts of Foxp3+ Tregs were detected between groups.

CONCLUSIONS AND CLINICAL RELEVANCE

In dogs with IRE, results indicated that evaluation of Foxp3+ Tregs did not have prognostic value, whereas a duodenal histologic score of 3 could be a negative prognostic factor for response and relapse, and higher severity scores for intraepithelial lymphocytes and lamina propria lymphocytes and plasma cells in duodenal biopsy samples may be negatively associated with response.
