Two cases of severe liver injury possibly related to 5-fluorouracil and calcium folinate

Practical guidelines for diagnosis and early management of drug-induced liver injury

The spectrum of drug-induced liver injury (DILI) is both diverse and complex. The first step in diagnosis is a suspicion of DILI based on careful consideration of recent comprehensive reports on the disease. There are some situations in which the suspicion of DILI is particularly strong. Exclusion of other possible etiologies according to the pattern of liver injury is essential for the diagnosis. In patients with suspected DILI, diagnostic scales, such as the Councils for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method (CIOMS/RUCAM) scale, may be helpful for the final diagnosis. Early management of DILI involves prompt withdrawal of the drug suspected of being responsible, according to serum levels of alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total bilirubin (T-Bil). However, as DILI patients may show resolution of liver injury without discontinuation of the drug, it should be carefully evaluated whether the suspected drug should be discontinued immediately with adequate consideration of the importance of the medication.

Drug-induced liver injury in 2007

PURPOSE OF REVIEW

To summarize the pertinent literature on the causes, epidemiology, prevalence, clinical features, evaluation and mechanisms of drug-induced liver injury reported during 2007.

RECENT FINDINGS

Although the frequency of drug-induced liver injury remains low, new data from the Centers for Disease Control and Prevention confirm that of the approximately 1600 new acute liver failure cases annually, acetaminophen hepatotoxicity accounts for 41%; among children with acute liver failure, acetaminophen was the second most common cause. Antimicrobials lead the list of non-acetaminophen causes of drug-induced liver injury. In Asia, herbal compounds are the most common causes of the condition. Pravastatin was shown to be safe in patients with nonalcoholic fatty liver disease or chronic hepatitis C. The US Food and Drug Administration issued a draft guidance document on the premarketing clinical evaluation and stopping rules of drug-induced liver injury signals, including Hy's Law cases in clinical trials.

SUMMARY

The year 2007 brought with it several reminders of the importance of drug-induced liver injury in the clinical trial as well as the clinical practice setting. There is additional evidence that statin drugs may be used safely in patients with chronic liver disease. Comments received by the US Food and Drug Administration to finalize their guidance document are eagerly awaited.
