As in humans, the clinical symptoms of equine OA are persistent pain and dysfunction of the affected joint. Its pathology is similarly marked by progressive deterioration of the articular cartilage, subchondral bone sclerosis, marginal osteophytes, soft tissue inflammation and joint effusion. Disease pathogenesis is mediated by elevated levels of inflammatory cytokines and proteolytic enzymes in the articular tissues and synovial fluid. Existing pharmacologic agents can alleviate OA joint pain; none are able to inhibit erosive disease progression. As several gene-based treatments for human disease have received approval by the Food and Drug Administration (FDA), the transition to veterinary medicine will almost certainly follow. Several viral vector systems have demonstrated highly efficient gene transfer to the equine joint, enabling expression of therapeutic transgenes at efficacious levels for well over a year. Because of its large size, the equine joint is well suited to studies of gene-based therapies for arthritic disease. The forelimb joints are vulnerable to OA onset, and treatment and diagnostic modalities are the same in humans and horses. Here, we discuss the various gene-transfer approaches under investigation and the current progress toward the development an effective gene therapy for equine OA.","PeriodicalId":35701,"journal":{"name":"Journal of Equine Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89820153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Viewed from the ground surface of the foot, front feet were more rounded and significantly larger than hind feet. Measures of medial-lateral balance and toe-heel angle ratio were within the recommended healthy guidelines for horses. Hoof pastern axis was broken forward for the studied animals, which supports previous research suggesting that a broken forward hoof pastern axis is normal for donkeys, although further study would be required to confirm whether this conformation is natural. Significant correlations were found between estimated body mass and hoof width in both the front and hind feet.

This has led to little direct correlation of cause and effect with no definitive conclusions drawn. The need to be objective is highlighted by the limited number of studies and that two studies used anecdotal evidence to support their hypothesis and thus creating the question does hindlimb proximal suspensory desmopathy predispose horses to sacroiliac disease?

Paralytic ileus is most frequently seen following abdominal surgery on the small intestine in horses. Three main mechanisms are involved separately or simultaneously in its causation, namely neurogenicendocrinic, inflammatory-endotoxic and pharmacological mechanisms. Regardless of the cause, equine paralytic ileus can be fatal, if not properly diagnosed and treated. Over the past 22 years (1997–2019), we have diagnosed and treated more than 180 horses with postoperative ileus using differing methods. Based on our results and experience, and that of others, we have developed a multimodal strategy to reduce the incidence of postoperative ileus. This has resulted in effective treatment of ileus-diagnosed patients in 94% of cases, a significant improvement in survival rates over the last 20 years. In this review, we described pre-, intra-, and postoperative multiple supplementary preventative and treatment procedures that cure this condition. These methods are dependent on individual cases but include the control of endotoxemia and inflammation, as well as using the least traumatic surgical techniques, carrying out the pelvic flexure colotomy, improved anesthesia techniques, treating with continuous postoperative peritoneal lavage, the use of fluid, antibiotic and NSAIDs therapy, according to a scheme the use of different prokinetic agents (including metoclopramide, neostigmine methylsulfate and domperidone), nasogastric decompression, management to minimize the surgical and postoperative stress reaction and judicious timing of postoperative feeding of horses.","PeriodicalId":35701,"journal":{"name":"Journal of Equine Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80006584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
