Summary
Cholangiohepatitis in adult cattle is rare and difficult to diagnose due to unspecific clinical signs. This study defines its characteristics, treatment, and outcomes in affected cows.
Area of Science:
- Veterinary Medicine
- Bovine Pathology
- Gastroenterology
Background:
- Cholangiohepatitis in adult cattle is poorly understood, lacking defined characteristics, treatment protocols, and outcomes.
- Limited data exists on the signalment, clinicopathologic, bacteriological, histopathological, and ultrasonographic features of this condition.
Purpose of the Study:
- To define the signalment, clinicopathologic, histopathological, and ultrasonographic characteristics of cholangiohepatitis in adult cattle.
- To describe treatment strategies and outcomes for adult cattle diagnosed with cholangiohepatitis.
Main Methods:
- A retrospective study analyzed medical records of 13 Holstein cows diagnosed with cholangiohepatitis.
- Inclusion criteria required cattle older than 3 months with histopathological confirmation of cholangiohepatitis.
Main Results:
- Clinical signs included anorexia, fever, tachycardia, and icterus, with yellow discoloration noted in some cases.
- Clinicopathologic findings revealed leukocytosis, neutrophilia, hyperfibrinogenemia, hyperglobulinemia, hypoalbuminemia, and elevated liver enzymes (GGT, AST, ALP) and bilirubin.
- Histopathology showed various forms of cholangiohepatitis, with 6 cows discharged and 7 euthanized.
Conclusions:
- Cholangiohepatitis is an uncommon condition in adult cattle.
- Antemortem diagnosis is challenging due to non-specific clinical presentations.
- Further research is needed to improve diagnostic and therapeutic approaches.

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

1.4K
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

980
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
