          Abstract

          RESUMEN Las úlceras gástricas se definen como la pérdida de continuidad de la mucosa gástrica. Se originan principalmente por desequilibrio entre factores injuriantes y de protección del estómago. Generalmente se manifiestan con signos como pérdida de peso, cólico, bruxismo e inapetencia, conllevando al bajo rendimiento del animal y pérdidas económicas. El objetivo del presente estudio fue determinar la prevalencia y factores de riesgo para la presentación de SUGE en CCC del Valle de Aburra. Se realizó gastroscopia a 100 animales de diferentes pesebreras, entre dos y 25 años de edad; cada estómago se caracterizó macro y microscópicamente. Las lesiones macroscópicas se valoraron de acuerdo con el grado de lesión según el Equine Gastric Ulcer Council, y la clasificación microscopica se basó en una adaptación hecha por patrones de descripción de lesiones más utilizados como: The sidney system y Equine gastritis grading system (EGGS). Para el análisis de los resultados, se tuvieron en cuenta variables como la intensidad del ejercicio, alojamiento, tipo y frecuencia de alimentación, transporte y frecuencia del mismo. El 65% de los equinos evaluados presentaron lesiones compatibles con SUGE. Macroscópicamente el grado 2 de severidad fue el más común (38%), con mayor presentación en la región aglandular. Microscópicamente el edema en la región fundica y pilórica fue la lesión más frecuente (35,2% y 30,7%, respectivamente). Los principales factores de riesgo asociados a la presentación de las lesiones fueron el transporte de los animales y la intensidad del ejercicio.

          ABSTRACT Gastric ulcers are defined as the loss of continuity of the gastric mucosal. They are mainly caused by an imbalance between harmful and protective factors of the stomach. It generally manifests itself with signs such as weight loss, colic, bruxism and inappetence, which can lead to low performance and economic losses. The objective of the present study was to determine the prevalence and risk factors for the presentation of SUGE in CCC of the Valle del Aburra. Gastroscopy was made to 100 animals from different stables, between two and 25 years of age; each stomach characterized, macro and microscopically. Lesions are evaluate depending on the degree of injury to the "Equine Gastric Ulcer Council". Microscopic lesions classification was based on an adaptation by patterns most commonly used description of injuries such as: the Sidney System and the equine gastritis grading system (EGGS). For the analysis of the results, variables such as exercise intensity, accommodation, type and frequency of feeding, transportation and its frequency were taken into account. 65% of the equines evaluated presented SUGE-compatible lesions, of which the most common degree of severity macroscopically was grade 2 (38%), with grater presentation in the non-glandular region. Microscopically, edema in the fundic and pyloric region was the most frequent (35.2% and 30.7%, respectively). The main risk factors associated with the presentation of the lesions were the transport of the animals and the intensity of the exercise.

          Risk factors associated with equine gastric ulceration syndrome (EGUS) in 201 horses in Denmark.

          The prevalence (up to 93% in Thoroughbred racehorses) and severity of equine gastric ulceration syndrome (EGUS) has been associated with type of training and differing management practices. However, there have been few studies to confirm these findings in nonracehorses in Europe. To investigate the prevalence of EGUS in a population of Danish horses, during winter when the horses had been housed and fed for at least 8 weeks and to analyse the influence of feed, work level and environment on the risk of EGUS of > or = grade 2 in severity. A total of 201 horses, not in active race-training, were evaluated, representing 23 different stables from all 5 regions within Denmark. All horses were considered to be healthy and not on medical treatment for EGUS. Endoscopically observed ulcer lesion scores were based on the number present (0-4) and severity (0-5). Univariate and multivariable mixed effects logistic regression models were developed using EGUS score as the dependent variable. An ulceration severity score of > or = 2 was regarded as being clinically significant. Separate models were developed for horses with ulcers in either the glandular or nonglandular regions of the stomach graded > or = 2 (EGUS > or = 2) and for those horses that had nonglandular ulcers graded > or = 2 (NG > or = 2). In this population, 53% (107/201) of horses were graded as having EGUS > or = 2 with 95 (47%) horses having NG > or = 2. Three variables were significantly (P or = 2: straw being the only forage available; exceeding 2 g/kg bwt of starch intake/day or >1 g/kg bwt/meal; and water not being available in the turn out paddock. Risk of NG > or = 2 significantly increased when straw was the only forage available, 1 g/kg bwt of starch/meal was exceeded, water was not available in the turnout paddock and the interval between forage feeding was >6 h. This study has confirmed that components of the diet, readily modifiable, may have an important impact on the risk of EGUS in the nonracehorse. Differences in the multivariable models produced for all ulcers and nonglandular ulcers support differences in the aetiology of ulcers in different locations of the stomach.

            Prevalence of gastric ulcer syndrome in high-level endurance horses.

            Equine gastric ulcers syndrome (EGUS) prevalence studies are rare in the endurance horse and none has been carried out to date in horses competing at high level. To determine the prevalence of EGUS in high-level endurance horses. Thirty endurance horses competing at high level were selected and submitted to 2 gastroscopic examinations. The first gastroscopy was performed during the interseason period, and the second during the competition season within 2-3 days following a ride of 90-160 km. Data related to housing, feeding, training system as well as age, breed and gender were recorded for each horse. The prevalence of squamous gastric ulcers was 48% during the interseason period (mean score 0.85 ± 0.13 on a scale from 0-4) and 93% during the competition season (mean score 1.60 ± 1.15) with a highly significant difference between the seasons (P = 0.001). Most of the lesions were situated in the squamous portion of the stomach but 33.3% of horses showed also glandular lesions. Significant influence of training and performance level on the gastric score (according to the distance of the ride preceding the second gastroscopy) was shown (P = 0.038). There was also a significant influence of housing on the gastric score (P = 0.002) showing higher scores in the horses kept totally on pasture (mean score: 2.14 ± 0.14) vs. horses housed in a mixed environment (stable + pasture, mean score: 1.43 ± 0.17). Both the pastured and (stabled + pastured) groups were receiving a grain supplement but the pastured group received a higher daily starch intake, which might explain the higher ulcer prevalence. There was no influence of age, breed or gender on the gastric scores. The high prevalence of gastric lesions observed in this study is probably related to the high level of training and performance of the horses examined compared to the population of horses included in the prior study. This prevalence of EGUS in high-level endurance horses is comparable to the prevalence established in racing horses. The equine veterinarians may take into consideration EGUS as a potential cause of poor performance. © 2010 EVJ Ltd.

              The prevalence and anatomical distribution of equine gastric ulceration syndrome (EGUS) in 201 horses in Denmark.

              The prevalence (up to 93% in Thoroughbred racehorses) and severity of equine gastric ulceration syndrome (EGUS) have been correlated with the type of training and associated management practices. However, there have been few reports to confirm these findings in nonracehorses in Europe. To describe the prevalence, anatomical distribution, severity and number of gastric ulceration lesions in a population of Danish pleasure horses; and to investigate differences for groups based on age, breed type and workload. A total of 201 horses not in active race-training, age 7 months-27 years, were evaluated, representing 23 different stables from all 5 regions of Denmark. These horses were considered to be healthy by the owner and not on veterinary treatment for EGUS. Endoscopically observed ulcer lesion scores were based on the number present (0-4) and severity (0-5). The presence or absence of ulcers in the glandular and/or nonglandular regions of the stomach was recorded and which site the most severe ulcers were found. The prevalence of EGUS severity score > or = 2 was 53%. The most severe lesions were commonly observed at the margo plicatus. Although older horses were not more likely to be affected by clinically significant EGUS they were more likely to have lesions in both the glandular and nonglandular regions. Differences in location of EGUS lesions were identified in different age groups, breed types and in horses exposed to different levels of work. This study confirms that gastric ulceration can be prevalent in a group of apparently clinically normal horses, not in intensive work. Further investigation of reasons for differences in EGUS location between different populations may aid toward the development of novel preventive measures.
