Giant Cell Arteritis Presenting as Cholestatic Hepatitis

1Children's Hospital Westmead, Westmead, Australia.
Background:
Severely deranged liver function tests (LFTs) are an atypical presentation of giant cell arteritis (GCA). Atypical presentations of GCA may result in missed or delayed diagnosis. This increases the risk of visual loss, the most feared outcome of GCA. Our patient presented with significant cholestatic derangement of his LFTs with a peak alkaline phosphatase level (ALP) of 3091 IU/L, which is the highest published level for patients with GCA. Case Presentation. Our patient was investigated for abnormal LFTs associated with sinus pain, fevers, and a dry cough. Bilateral temporal artery biopsies confirmed GCA. His symptoms and LFTs improved with corticosteroids.
Conclusion:
This is an unusual presentation of GCA and highlights the need to consider GCA in patients with unexplained cholestatic LFT abnormalities.

Chronic Pancreatitis I: Introduction
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...
Diseases of the Liver and Gallbladder
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...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
