Amiodarone, a commonly used antiarrhythmic agent, has numerous adverse effects. The purpose of this case report is to highlight its hepatotoxicity, an unusual complication of long term amiodarone therapy. Our patient is a 76-year-old man with underlying ischaemic heart disease and recurrent ventricular tachycardia. Eleven months after commencing amiodarone, he developed asymptomatic raised aminotransferases which resolved following drug withdrawal. Amiodarone was then reintroduced and four years later, the patient developed hepatomegaly, worsening liver biochemistry and histopathological changes consistent with early cirrhosis. His symptoms improved following discontinuation of amiodarone. However, hepatomegaly and a low serum albumin still persist four years later.

Amiodarone has been reported to cause asymptomatic increases in liver function tests in 15-55% of patients. Clinically apparent, symptomatic hepatic disease occurs less frequently, but patients have been reported to have hepatomegaly, jaundice, cirrhosis, or chronic active hepatitis. Less well recognized is the fact that amiodarone has been attributed to six deaths. We cared for a patient with amiodarone hepatotoxicity, which led us to review the literature associated with this serious condition.

Amiodarone has proved very effective in the treatment of otherwise resistant cardiac tachyarrhythmias. The use of amiodarone has, however, been limited due to its serious side-effects. A patient with cholestatic hepatitis due to amiodarone treatment is presented below and a review of the hepatotoxicity of amiodarone is given. It is concluded that solid evidence exists of hepatic injury due to amiodarone treatment, including steatosis, alterations resembling alcoholic hepatitis, cholestatic hepatitis and micronodular cirrhosis of the liver. Patients receiving amiodarone should be regularly screened with respect to hepatic enzyme levels. Therapy should be discontinued on the suspicion of cholestatic injury or hepatomegaly.

Muscle weakness, neuropathy, and transient rises in hepatic enzyme activity have been reported with the use of the antiarrhythmic agent amiodarone. A 68 year old teetotaller with normal liver function was given amiodarone for resistant supraventricular arrhythmias. He presented 19 months later with vomiting, muscle weakness and wasting, sensory neuropathy, and hepatomegaly. Liver biopsy showed fibrosis and the presence of hyaline. The amiodarone was withdrawn. Three months later he developed ascites. Oesophageal varices were found and he later died. The liver showed micronodular cirrhosis. The large volume of distribution and long half life of amiodarone may explain the persistence of toxicity, which may have been aggravated by simultaneously administered doxepin in this case. Amiodarone should be withdrawn if abnormal liver function or neuropathy develops.

Amiodarone is an antiarrhythmic drug widely used to treat a variety of supraventricular and ventricular arrhythmias. However its drawback is a very slow elimination and very frequent adverse effects (thyroid, pulmonary, neurologic, ocular, dermatologic, hepatic disorders). We describe a patient who developed a pseudoalcoholic liver disease and a cirrhosis after use of Amiodarone for a long period of time.

Amiodarone is one of the most effective antiarrhythmic drugs available and is widely prescribed despite several potentially life-threatening side-effects. Hepatotoxicity is the most frequent one during long-term oral therapy: occasionally acute hepatitis necessitates the suspension of treatment but monitoring of a transient increase in serum aminotransferases is usually sufficient; the clinical-morphological pictures of liver cirrhosis have also been reported. Fulminant hepatitis soon after a parenteral load of the drug is far less well described in the literature. Most published cases were reversible after the suspension of treatment. A negative challenge after oral amiodarone exposure suggested that polysorbate 80, a solvent added to the intravenous infusion and already implied in the pathogenesis of a similar syndrome observed in infants, is a more likely cause of this complication. The occurrence of acute hepatitis complicating parenteral amiodarone treatment does not preclude subsequent oral use of the drug: an evidence-based therapeutic behavior now definitively consolidated. Because of the rarity of this diagnosis, we report 3 cases of short-term hepatotoxicity secondary to amiodarone treatment for supraventricular tachyarrhythmias: in 2 male patients with dilated cardiomyopathy and in a female with liver disease. The diagnosis was presumptive and based on a thorough drug history, the temporal relationship, the time-course of liver dysfunction, the exclusion of other causes and on the rapid improvement observed after parenteral amiodarone withdrawal in 2 cases; in no case could we find any other explanation for the liver damage. Since amiodarone is sometimes still an irreplaceable antiarrhythmic drug, we raise the question of whether careful and continuous vigilance should be mandatory in patients receiving the drug or whether it is possible to introduce a pharmaceutical preparation not containing the vehicle that induces acute liver toxicity.

Amiodarone is a commonly used anti-arrhythmic in elderly patients. Abnormal liver function is frequently reported with its use but clinically symptomatic disease is rare. Hepatomegaly, cholestasis, acute hepatitis and rarely fulminant liver failure have been recorded [1, 2], however amiodarone toxicity presenting with cirrhosis is exceedingly rare. Toxic effects of amiodarone are well described with higher dosage but severe hepatic toxicity and cirrhosis with low dose amiodarone has not been reported in the English language literature. We present a report on a patient with pseudo-alcoholic cirrhosis with low dose amiodarone.

Amiodarone chlorhydrate is a diiodated benzofuran derivative, and it is used to treat cardiac rhythm abnormalities. Hepatotoxicity is a relatively uncommon side effect of amiodarone, and symptomatic hepatic dysfunction occurs in fewer than 1% of the patients taking amiodarone. Cirrhosis is a rare complication that's been confirmed in 12 cases. Peripheral neuropathy occurs in 10% of patients taking aminodarone. We report here on an unusual case of amiodarone-induced hepatotoxicity and peripheral neurotoxicity. A 75 year old man with normal liver function was given amiodarone for treating his atrial fibrillation and heart failure. He developed nausea, vomiting, muscle weakness and wasting after 17.8 months therapy with amiodarone (400 mg orally once per day). Liver biopsy showed the presence of foam cells in the hepatic sinusoids and Mallory bodies in the periportal hepatocytes on light microscopy. Sural nerve biopsy showed demyelination, and nerve conduction studies showed mixed sensorimotor polyneuropathy. These observations show the necessity of monitoring the hepatic function and conducting neurologic examination of the patients treated with amiodarone.

Amiodarone is used commonly in patients with cardiac diseases. Common side effects include thyroid dysfunction and hepatic abnormalities. However, recently there has been concern for developing liver cirrhosis secondary to amiodarone therapy. We present two cases of liver cirrhosis in patients taking amiodarone. Their clinical presentation as well as histological features are discussed in detail.

Nonalcoholic steatosis/steatohepatitis is the most common cause for abnormal liver chemistries. Apart from metabolic syndrome, drugs may also lead to development of steatohepatitis that may, rarely, progress to cirrhosis and portal hypertension. We discuss a case of amiodarone-induced steatohepatitis with advanced fibrosis, presenting with hepatic decompensation and portal hypertension manifesting as ascites and recurrent esophageal variceal hemorrhage. Amiodarone is a lipophilic drug that concentrates in the liver and usually, over a period of time, leads to toxicity related to drug accumulation. There is marked histological similarity between amiodarone-induced liver disease and alcoholic and nonalcoholic steatohepatitis. The clinical manifestations of amiodarone-induced hepatotoxicity and the mechanism of toxicity are also discussed.
