title: [Autoimmune hepatitis complicated by intolerable pain of lower extremities and shock due to azathioprine].
abstract: A 24-year-old woman was followed for about ten months with oral administration of prednisolone (22.5-35 mg/d) for autoimmune hepatitis. In June 1995, she noticed fatigue and appetite loss and blood chemistry revealed markedly deteriorated liver function. She was admitted to our hospital. The daily dose of prednisolone was increased to 60 mg. Her elevated levels of transaminases decreased gradually. Administration of azathioprine (100 mg/d) was started with tapering of prednisolone on August 18th. Ten days later, tender cervical lymphadenopathy and high fever occurred. Azathioprine administration was stopped immediately and intravenous antibiotics were given. On September 5th, 50 mg of azathioprine was administered again. Two hours later, the patient complained of intolerable pain from the lumbar region to the knee joints, which subsided following two injections of analgesics within a few hours. However, chills, high fever and hypotension (86/30 mmHg) subsequently developed. No bacterial growth was detected in blood culture. She was discharged on September 12th. On October 4th, she visited our out-patient clinic. The next day, she took one tablet (50 mg) of azathioprine at 10 o'clock. She noted intense pain from the thighs to the knees and calves around noon again. Her home doctor found that she exhibited shock (BP 67/?). She was immediately taken to our department. The same symptoms and signs as the above-mentioned occurred. Azathioprine was considered responsible for these two adverse reactions (shock) as an allergen. Later, systemic lupus eythematosus was diagnosed in 1996. And she died to pulmonary hypertension in May 1999. Physicians should be aware of the potential adverse effect of azathioprine administered in order to manage the patients with autoimmune disorders.
