A 66 year-old obese woman with arthrosis, self-medicated with oral nimesulide, 200 mg daily. After 6 weeks she developed nausea, jaundice and dark urine. Two weeks later she had recurrent hematemesis and was hospitalized. Besides obesity and anemia her physical examination was unremarkable. An upper GI endoscopy revealed 3 acute gastric ulcers and a 4th one in the pyloric channel. Abdominal ultrasonogram showed a slightly enlarged liver with diffuse reduction in ecogenicity; the gallbladder and biliary tract were normal. Blood tests demonstrated a conjugated hyperbilirubinemia (maximal total value: 18.4 mg/dl), ALAT 960 U/l, ASAT 850 U/l, GGT 420 U/l, alkaline phosphatases mildly elevated, pro-time 49% and albumin 2.7 mg/dl. Serum markers for hepatitis A, B and C viruses were negative. ANA, AMA, anti-SmA, were negative. Ceruloplasmin was normal. A liver biopsy showed bridging necrosis and other signs of acute toxic liver damage. Gastric ulcers healed after conventional treatment and hepatitis subsided after 2 months leaving no signs of chronic liver damage. The diagnosis of toxic hepatitis due to nimesulide was supported by the time-course of drug usage, sex, age, absence of other causes of liver disease, a compatible liver biopsy and the improvement after drug withdrawal. Peptic ulcers or toxic hepatitis have been previously described as independent adverse reactions in patients taking nimesulide or other NSAIDs but their simultaneous occurrence in a single patient is a unique event that deserves to be reported.

Sevoflurane, a halogenated anesthetic, is associated with mild aminotransferase elevations but does not tend to cause clinically significant hepatotoxicity. We report a rare case of severe hepatic necrosis following exposure to sevoflurane during surgery. A 37-year-old man presented with nausea,vomiting, abdominal pain, and jaundice on the third postoperative day after an abdominal wall mass resection. Laboratory tests showed markedly elevated aminotransferase levels, hyperbilirubinemia, and coagulopathy. His viral hepatitis and human immunodeficiency virus (HIV) serologies were negative for acute infection, and his Epstein-Barr virus (EBV) and cytomegalovirus (CMV) serologies were suggestive of recent EBV infection and remote CMV infection. Antinuclear antibody and anti-smooth muscle antibody screens were negative. Ceruloplasmin and serum copper values were in the normal range. The histopathological findings included an acute centrilobular cholestatic hepatocellular injury compatible with the clinical history of acute drug-induced hepatotoxicity. The patient improved with conservative management. Unlike other halogenated anesthetics, proposed mechanisms of sevoflurane hepatotoxicity include production of compound A, increased cytosolic free Ca(2+), and activation of free radical metabolizing enzymes. The patient was likely susceptible to toxicity due to an underlying EBV infection and a probable history of exposure to halogenated anesthetics. Sevoflurane is generally considered to be relatively safe for subjects with mild liver dysfunction, in comparison with other halogenated anesthetics. However, this case suggests that sevoflurane can lead to severe life-threatening hepatic necrosis in at-risk individuals.
