Antimicrobial-associated acute hepatitis
Abstract
Recently, the case history of a 44-year-old woman who experienced acute hepatitis subsequent to therapy for chronic sinusitis was reviewed. The patient sequentially was administered clarithromycin, levofloxacin, amoxicillin-clavulanate, and gatifloxacin. Her adverse events were attributed definitively to gatifloxacin, a surprising conclusion because many other possible causes of hepatitis existed in this case. Not ruled out as potential causes of the clinical and laboratory adverse events were hepatitis other than hepatitis A or B. Other antimicrobials administered were dismissed. In particular, extended treatment with amoxicillin-clavulanate has been clearly linked to hepatotoxic effects that may occur long after therapy begins. Thus, while we agree that physicians must be aware of the potential for antimicrobial hepatotoxicity, we believe that this case study is not a solidly documented case of hepatitis attributable to gatifloxacin and overlooks other possible causes of acute hepatitis of which prescribers should be aware.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
