Clarithromycin-induced acute liver injury in a patient with positive Helicobacter pylori: a case report and review of the literature

INTRODUCTION AND IMPORTANCE: While 14-day triple therapy with clarithromycin is a common approach for eradicating Helicobacter pylori infection, it is essential to note that this treatment does not come without potential side effects. CASE PRESENTATION: We present the case of a 34-year-old male who presented to the emergency department with severe vomiting and abdominal pain. Subsequent evaluation revealed that the patient had developed drug-induced liver injury (DILI). CLINICAL DISCUSSION: DILI can cause acute hepatocellular or cholestatic damage, and chronic injury can lead to hepatocellular, cholestatic, vascular, or neoplastic manifestations. CONCLUSION: Clinicians should exercise caution and be alert to the potential hepatotoxic effects of medications, especially when initiating triple therapy for H. pylori infection.
