Topic:Acute Disease in Horses
Acute disease in horses refers to a sudden onset of illness or medical condition that develops rapidly and may require immediate attention. These conditions can affect various systems, including the respiratory, gastrointestinal, musculoskeletal, and nervous systems. Causes of acute disease may include infections, trauma, metabolic imbalances, or toxic exposures. This page compiles peer-reviewed research studies and scholarly articles that examine the characteristics, causes, and management of acute diseases in horses.
Evaluation of changes in microbiota after fecal microbiota transplantation in 6 diarrheic horses. The purpose of this study was to characterize the fecal microbiota of horses with acute and chronic diarrhea before and after fecal microbiota transplantation (FMT). Six client-owned horses with acute and chronic diarrhea received FMT from 2 healthy donor horses. Microbiota analysis using next-generation sequencing was performed on fecal samples collected before and 2 and 7 d after FMT. Signs of diarrhea improved in 4 horses, whereas the remaining 2 horses did not survive. There was a significant difference in the number of bacterial species between donors and recipients (P < 0.05). The Order ...
The Potential of Mesenchymal Stem Cells to Treat Systemic Inflammation in Horses. One hallmark of mesenchymal stem cells (MSCs) is the ability to differentiate into multiple tissue types which assists in tissue regeneration. Another hallmark of MSCs is their potent anti-inflammatory and immunomodulatory properties and the potential to treat inflammatory, immune-mediated, and ischemic conditions. In equine practice, MSCs have shown efficacy in the treatment of musculoskeletal disorders such as tendinopathy, meniscal tears and cartilage injury. However, there are many equine disease processes and conditions that may benefit from the immunomodulatory properties of MSCs. Exampl...
Cortisol, adrenocorticotropic hormone, serotonin, adrenaline and noradrenaline serum concentrations in relation to disease and stress in the horse. No detailed comparative data are available on the hormonal parameters of horses suffering from a number of diseases. The aim of our study was to measure concentrations of cortisol, adrenocorticotropic hormone (ACTH), serotonin, adrenaline and noradrenaline in horses with various diseases and following surgery, to assess the response of the HPA axis and adrenal medulla. Blood samples were obtained from six groups of horses comprising a total of 119 animals as follows: laminitis, acute abdominal syndrome (AAS), castration surgery, acute diseases, chronic diseases and healthy controls. Serum horm...
Effects of topical application of pirfenidone ointment on thermoplasty-induced acute lameness in a double-blind and acute and chronic lameness of musculoskeletal origin in an open multi-centered field trial in horses. The effectiveness of pirfenidone ointment against thermoplasty-induced acute foreleg lameness in a double-blind study, and against acute and chronic lameness of musculoskeletal origin in an open multi-centered field trial was evaluated in this study. Thermoplasty was performed on both inner forelegs at designated locations of each horse under anesthetics. A 10% pirfenidone or placebo ointment was topically applied starting 24 hours after the thermoplasty three times daily for 7 days. For acute and chronic lameness of musculoskeletal origin, pirfenidone ointment was also applied one to three ti...
Intra-abdominal adhesions in horses: a retrospective evaluation of repeat laparotomy in 99 horses with acute gastrointestinal disease. The objectives of this study were (1) to determine the prevalence of pathological abdominal adhesion formation following exploratory laparotomy; (2) to establish the site of adhesion formation and its relationship to the initial lesion; (3) to ascertain whether the development of intra-abdominal adhesions decreases long-term survival and (4) to identify risk factors for adhesion formation. Of 1014 horses treated surgically for acute gastrointestinal disease, 113 (10.1%) were subjected to repeat laparotomy, with surgical records available for 99 of these cases. Pathological adhesions were the m...
An investigation of the ability of the glutaraldehyde test to distinguish between acute and chronic inflammatory disease in horses. The glutaraldehyde test (GT), a rapid and inexpensive test, has been utilized empirically for many years in bovine practice for diagnosing inflammatory diseases. GT is used primarily to demonstrate increased serum concentrations of fibrinogen and globulin. Glutaraldehyde binds with free amino groups in fibrinogen and immunoglobulin to create a clot in a first degree chemical reaction. The clotting time of the GT estimates the content of proteins produced in response to inflammation. The applicability of GT for diagnosing inflammation in the horse has never been investigated. The objective of t...
Historical perspectives on laminitis. This article attempts to provide a historical perspective regarding equine laminitis. It is designed to cover, as completely as possible, the historical record of, and the research advances made, in regards to acute and chronic laminitis. With respect to the historical record, the names given to this disease, the postulated etiologies, and the various treatment protocols are discussed. This article demonstrates the historical longevity of this disease and establishes a background for the current understanding of the disease's pathologic mechanisms and treatments.
Age, breed, sex and seasonality as risk factors for equine laminitis. A case-control study was conducted at the Texas Veterinary Medical Center between January 1, 1986 and December 31, 1991. Logistic regression was used to assess age, breed, sex, and seasonality as risk factors for equine laminitis. There were 70 acute cases, 183 chronic cases, and 779 controls. No statistical association was found between age, breed, sex, or seasonality and the diagnosis of acute laminitis. For chronic cases, the estimated odds ratio was statistically significant for age (OR = 1.05, 95% CI (1.02, 1.08)) and for the diagnosis of laminitis in the third quarter of the year (OR = 2...
Pleural effusion associated with acute and chronic pleuropneumonia and pleuritis secondary to thoracic wounds in horses: 43 cases (1982-1992). Case records of 43 horses with pleural effusion associated with acute pleuropneumonia, chronic pleuropneumonia, or pleuritis secondary to a penetrating thoracic wound were reviewed to determine the predisposing factors, diagnosis, and treatment of this condition. Acute pleuropneumonia was diagnosed in 36 horses, the majority of which were Thoroughbreds (89%). Of 22 (61%) horses that were in race training at the onset of illness, 11 (31%) had been recently transported a long distance and 4 (11%) had evidence of exercise-induced pulmonary hemorrhage. Physical examination findings and hematologic...
Fecal leukocytes and epithelial cells in horses with diarrhea. Fecal samples from 74 horses with diarrhea were examined microscopically for leukocytes and epithelial cells. The diarrhea was categorized as either acute (less than two weeks) or chronic, Salmonella positive or negative, and mild or severe (based on the fecal consistency). A large number of fecal leukocytes was strongly suggestive of salmonellosis; however, approximately 1/3 of the horses with Salmonella-negative diarrhea also shed fecal leukocytes. Fecal leukocytes were more common in horses with acute and/or severe diarrhea regardless of cause. Numbers of fecal colonic mucosal epithelial ce...
