Complete Blood Count-Derived Inflammatory Markers Changes in Dogs with Chronic Inflammatory Enteropathy Treated with Adipose-Derived Mesenchymal Stem Cells

Adipose-derived mesenchymal stem cells (Ad-MSCs) exhibit anti-inflammatory and immunomodulatory activities. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) have been reported as novel biomarkers of the inflammatory state; however, they have never been examined in dogs with chronic inflammatory enteropathy (CIE) treated with Ad-MSCs. This study aimed to compare the clinical evolution and the changes in the NLR, PLR, and SII in dogs with CIE before and after cell therapy. Sixteen dogs with CIE were administered a single intravenous dose of Ad-MSCs. The canine chronic enteropathy clinical activity index (CCECAI), NLR, PLR, and SII were assessed before treatment (T0) and at 2 (T2) and 9 (T9) months post-treatment and compared over time and with the reference values obtained from a group of healthy dogs. NLR, PLR, and SII were significantly increased at T0 compared to the reference values, decreasing significantly over time. At T9, the NLR and SII did not differ from the reference values, but PLR remained above the reference values. A correlation was observed between CCECAI and the three markers. These findings show that the clinical improvement of dogs with CIE treated with Ad-MSCs is accompanied by a normalization of the inflammatory status

Evaluation of the Two-Point Ultrasound-Guided Transversus Abdominis Plane Block for Laparoscopic Canine Ovariectomy

The transversus abdominis plane (TAP) block causes desensitization of the abdominal wall and peritoneum. Of all the approaches proposed to perform it, the two-injection-point TAP showed the best results in terms of the area reached by the anesthetic solution. However, to date, no clinical data exist. The aim of this study was to evaluate the intra- and postoperative analgesic efficacy of a two-injection-point TAP block in dogs undergoing laparoscopic ovariectomy. A total of 26 animals were assigned to receive general inhalation anesthesia (control group), and 26 dogs were assigned to general inhalation anesthesia combined with TAP block (TAP group). The ultrasound-guided TAP block was carried out with a subcostal and cranial-to-ilium injection per hemiabdomen. The end-tidal concentration of isoflurane (EtISO) was recorded at different moments during the surgery. Postoperative pain was assessed at different time points during the first 24 h after surgery. The control group required significantly higher EtISO concentration during the ovarian resection and showed higher postoperative pain scores than the TAP group. Fewer dogs in the TAP group required intra- or postoperative rescue analgesia. TAP block can be implemented to improve postoperative pain management after laparoscopy, reducing the dosage of the systemic drugs used and, hence, their possible side effects

Profile of canine patient with esophageal foreign bodies

Objective. Determine the profile of the canine patient with esophageal foreign bodies to identify risk factors associated with the foreign bodies. Materials and Methods. This is a retrospective study made by the Veterinary Hospital Clinic of the Universidad de Extremadura (VHC). Different factors were analyzed in dogs with an endoscopic diagnosis of esophageal foreign bodies. Results. This pathology was more commonly found in young adult dogs and in small breeds. This pathology was present for the first time in the Portuguese Warren Hound, which was also the breed with the highest risk. Conclusions. The results obtained in this investigation are in agreement with the previous description of a patient that presents esophageal foreign bodies. Also, the Portuguese Warren Hound was found to be predisposed to this problem, with a higher risk factor than other breeds previously mentioned in the literature. To prevent esophageal foreign bodies, dogs should be fed raw meat and bones, especially small breeds. This pathology should always be kept in mind in dogs with esophagitis symptomology regardless of age, although it is most common in young adult dogs.Objetivo. Determinar el perfil del paciente canino que presenta cuerpos extraños esofágicos para identificar las características de riesgo al presentar esta entidad. Materiales y métodos. Este es un estudio retrospectivo realizado en el Hospital Clínico Veterinario de la Universidad de Extremadura (HCV). Se analizaron diferentes parámetros de los perros que presentaron un diagnóstico endoscópico de cuerpos extraños esofágicos. Resultados. Esta patología se presentó más comúnmente en perros adultos jóvenes y en pacientes de raza pequeña. Se presenta por primera vez al Podenco Portugués, el cual además representó la raza con mayor factor de riesgo. Conclusiones. Los resultados obtenidos en esta investigación concuerdan con lo descrito anteriormente en cuanto a las características del paciente con cuerpo extraño esofágico. Asimismo, se reporta el Podenco Portugués como predispuesto a esta entidad, con un factor de riesgo mayor al de otras razas anteriormente mencionadas en la literatura. Para prevenir los cuerpos extraños esofágicos, se debe alimentar con carne cruda y huesos a los perros, especialmente a los de raza pequeña. Siempre se debe tener en cuenta esta patología en los perros con sintomatología de enfermedad esofágica sin importar su edad, pues su presentación es más común en perros adultos jóvenes

Relationship between serum cobalamin concentration and endoscopic ileal appearance and histology in dogs with chronic inflammatory enteropathy

Abstract Background It has not been determined whether ileal appearance differs among dogs with chronic inflammatory enteropathy (CIE) and different serum concentrations of cobalamin. Objective To compare endoscopic and histologic ileal findings in dogs with CIE and different serum cobalamin concentrations and then evaluate the correlation of ileal changes to cobalamin serum concentration using updated scoring systems to assess the ileum. Animals Sixty‐eight dogs with CIE. Methods Retrospective study. Frequency of ileal features and ileal histologic and endoscopic scores (IHS and IES) were obtained and compared among CIE dogs with severe hypocobalaminemia (SHC; 350 ng/L). The correlation of IHS and IES with cobalamin was evaluated. Results Friability, villus atrophy, crypt dilatation, epithelial injury, and intraepithelial lymphocytes were more frequent in SHC than in NC dogs (all P ≤ .01). Median SHC‐IES (2; range, 0‐4) was higher than NC‐IES (1; range, 0‐5; P = .004). Median SHC‐IHS (6; range, 3‐9) was higher than HC‐IHS (4; range, 1‐7; P 350 ng/L in CIE dogs. With updated scales to assess the mucosa, greater ileal damage was associated with lower serum cobalamin concentration

Gastroesophageal reflux in anesthetized dogs: a review

Gastroesophageal reflux can be a catastrophic illness in small animals during anesthesia since its complications can cause serious pathologies, such as esophagitis, esophageal stenosis and aspiration pneumonia. With an incidence from 12 to 78.5% in anesthetized dogs, gastroesophageal reflux is normally silent during anesthesia and will be notices only if regurgitation occurs and stomach acid is present in the nasal or oral cavities. In humans, gastroesophageal reflux disease (GERD) is a well-defined pathology where the lower esophageal sphincter has a sustained weakness. However, in dogs, gastroesophageal reflux disease as such is not well established, if at all; it has only been described as gastroesophagic reflux, occurring principally in anesthetized animals. There are several factors influencing the presentation of reflux in anesthetized dogs, which may be inherent to the patient (e.g. age, sex, breed, weight, or body condition), medications used prior to and during anesthesia, type of surgery or position of the animal during surgery. The objective of this review is to discuss a series of conditions that could predispose dogs to gastroesophageal reflux during anesthesia and to assist in the prevention and diagnosis of this condition
