Antibiotic induced liver injury: what about children?

Antimicrobial agents are important causes of drug-induced liver injury. They are responsible for about 45% of cases of drug hepatotoxicity. Hepatic damage mechanisms are intrinsic or idiosyncratic. Usually, antibiotics are responsible for idiosyncratic toxicity. This review summarizes the rate of incidence and clinical features of hepatotoxicity due to antibiotics and chemotherapics, with particular attention to data regarding paediatric population. Liver injury features have been systematically evaluated for the most commonly administered antibiotics and chemotherapics in adults, even though there is little information about other widely used compounds, as cephalosporine or clarithromycin, and about antibiotics active against multi-resistant bacteria, as carbapenems, vancomycin, clindamycin, and linezolid. By contrast, there is an abundance of case reports in paediatrics, but very few structured studies have been carried out in children. Children are an important class of antibiotic users, with specific metabolic characteristics, so more studies on them should be carried out.

Clinical and histopathologic features of fluoroquinolone-induced liver injury

BACKGROUND & AIMS

Fluoroquinolone-induced liver injury is rare; no prospective studies of well-characterized case series have been published. We studied patients with fluoroquinolone-induced hepatotoxicity from the Drug-Induced Liver Injury Network (DILIN) to characterize injury patterns, outcomes, and associated features.

METHODS

We identified subjects with fluoroquinolone hepatotoxicity enrolled in the DILIN from September 2004 to January 2010. Demographic, clinical, and laboratory data were analyzed by descriptive statistical methods.

RESULTS

Of the 679 registrants in the DILIN prospective study, 12 had fluoroquinolone hepatotoxicity (6 ciprofloxacin, 4 moxifloxacin, 1 levofloxacin, and 1 gatifloxacin). Seven were women; median age was 57 years (range, 23-80 years), and median time from fluoroquinolone start to symptoms was only 4 days (range, 1-39 days). Nine patients developed symptoms on medication; 3 did so 2, 8, and 32 days after stopping the medication. Cases were equally distributed among hepatocellular injury (predominantly increased levels of alanine aminotransferase), cholestatic injury (predominantly increased levels of alkaline phosphatase), and both. Seven patients had immunoallergic features. Patients with mixed hepatocellular and cholestatic injury had mild disease without jaundice; all recovered. In contrast, 2 of 4 patients with hepatocellular injury and jaundice died, 1 of acute liver failure. One patient with cholestatic injury developed vanishing bile duct syndrome and required liver transplantation; another had a persistently increased serum level of alkaline phosphatase.

CONCLUSIONS

Fluoroquinolone liver injury is rapid in onset and often has immunoallergic features, indicating a hypersensitivity reaction. The pattern of injury can be hepatocellular, cholestatic, or mixed; mixed cases are the least severe. Acute and chronic liver failure can occur.

Ciprofloxacin-Induced Hepatotoxicity Resolved with Levofloxacin: A Case Report and a Review of the Literature

Objective

To report a case of elevated hepatic transaminases in a patient receiving ciprofloxacin that resolved upon discontinuation and initiation of levofloxacin.

Summary

A 45-year-old white woman was initiated on ciprofloxacin and gentamicin after a blood culture revealed gram-negative rods. On day 2 of antibiotic therapy, the patient's aspartate aminotransferase (AST) and alanine aminotransferase (ALT) increased to 2,352 units/L and 783 units/L, respectively, and remained elevated for the following 4 days. Baseline AST and ALT were within normal limits. On day 5 of therapy, ciprofloxacin was discontinued and levofloxacin was initiated. On the following day, the hepatic transaminases decreased (AST, 192 units/L; ALT, 582 units/L) and continued to normalize prior to hospital discharge. On a subsequent admission later in the month, levofloxacin was again administered for treatment of a gram-positive bacteremia, with no subsequent elevation of hepatic transaminases.

Discussion

An objective causality assessment revealed that the adverse drug reaction (ADR) was probable. Although reports of this ADR have been noted, there is no previously documented occurrence of resolution of elevated hepatic transaminases on therapeutic modification to another fluoroquinolone.

Conclusion

Ciprofloxacin may significantly elevate hepatic transaminases. The clinician should be aware of the unique ADR profiles of the different fluoroquinolones because hepatotoxicity may not be a class effect.

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.

Ciprofloxacin-induced acute liver injury: case report and review of literature

Ciprofloxacin is a fluorinated quinolone antibiotic with relatively low occurrence of adverse side effects. However, increasing evidence suggests that ciprofloxacin may cause severe liver damage. Until now, 14 cases of ciprofloxacin-associated liver injuries have been reported. We describe a case of a 22-year-old male who developed hepatic failure after intake of ciprofloxacin. The patient had been treated with 2 x 250 mg ciprofloxacin per day. He presented with symptoms of acute liver failure 14 days later. Liver biopsy revealed extensive hepatocellular necrosis involving zones 3 and 2 of hepatic acini and a mixed inflammatory infiltration containing abundant eosinophils. Symptoms resolved after corticoidsteroid therapy. In the present paper, we report the clinico-pathological characteristics of a case of ciprofloxacin-associated acute hepatic failure and discuss the current literature.
