[Fulminate liver failure in a 39-year-old female patient with leukocytosis, unclear fever, and arthralgic pain].

Background: Fulminate liver insufficiency can have many causes and is a challenge for differential diagnosis.

Case Report: A 39-year-old woman was admitted because of a nonitching macular-papular exanthema on both thighs with spreading to the trunk. In addition, the patient complained of dysphagia, symmetrical arthralgias, myalgias, fever of 38 degrees C, and night sweats. An outpatient treatment with nonsteroidal antirheumatics, antihistamines and penicillin was started for 3 days before admission. On admission, a neutrophilic leukocytosis (23.6 Gpt/l), an increase in C-reactive protein (185 mg/l), and a ferritin level of 1,740 microg/l were found. Liver enzymes were increased (alanine aminotransferase 1.03 micromol/l.s, aspartate aminotransferase 1.06 micromol/l.s, gamma-glutamyltransferase 2.73 micromol/l.s, and lactate dehydrogenase 12.48 micromol/l.s). Sonographic examination showed a mild hepatosplenomegaly, but otherwise normal findings. X-rays of the lungs, hands, and ankles were normal. An echocardiography was within normal limits. Extensive serologic investigations including assays for hepatitides A, B and C as well as repeated blood cultures were negative. Antibiotic therapy was continued without any improvement. In addition, acetaminophen (4 x 1,000 mg/day) and ibuprofen (3 x 600 mg/day) were given. Liver function worsened and an icterus developed. The patient was transferred to the authors' university hospital. Because of the clinical findings of fever episodes, a typical macular exanthema, lymphadenopathy, hepatosplenomegaly, arthralgias, myalgias, dysphagia, and the presence of neutrophilic leukocytosis, fever, an increase in ferritin, but negative serologic titers and no bacteremia, a working diagnosis of Still's disease was made. The patient was treated with high-dose methylprednisone (250 mg/day for 3 days, then 100 mg/day). Liver biopsy revealed subacute hepatitis with necrosis and accompanying cholangitis. The prednisone therapy induced a fast remission and improvement of liver function, liver transplantation was not necessary. The patient is, 16 months after the incident, without symptoms under prednisone 3 mg/day, and the liver function is normal.

Conclusion: The etiology of Still's disease is unknown and the disease is characterized by fever episodes, a typical macular-papular exanthema, lymphadenopathy, hepatosplenomegaly, and arthralgias. A mild to moderate increase in liver enzymes is often found as part of this disease. Rarely, a fulminate liver failure has been described, particularly in the presence of co-administration of nonsteroidal antirheumatics or acetaminophen. Still's disease must be considered as part of the differential diagnosis of acute liver failure, because an early diagnosis and consequent therapy with prednisone may prevent the need for liver transplantation.
