핵심 내용

UNLABELLED: Drug-induced liver injury (DILI) is a challenging diagnosis since a wide variety of medicines can cause adverse reactions. Losartan is an angiotensin II receptor antagonist (ARA-II) approved for the treatment of arterial hypertension. The most common adverse effects are fatigue, anaemia, weakness and cough. An increase in transaminases has been reported with less frequency (<2% of cases). Although the mechanism is not fully understood, DILI onset is usually within 1-8 weeks of therapy, and hepatic enzymology usually normalizes 2-4 months after drug suspension. The authors present the case of a 66-year-old male patient with a medical history of arterial hypertension and a prior hospitalization (4 years previously) for drug-induced hepatitis, which, at the time, was attributed to a dietary supplement. Four years later, because of new onset of hypertension, losartan was reintroduced. After 3 weeks, the patient was admitted to the emergency department with complaints of acute abdominal pain associated with asthenia, nausea and increased abdominal volume that had first developed 8 days previously. After exclusion of other causes, DILI associated with losartan was assumed. This is a very rare adverse effect since only seven cases have been described in the literature. LEARNING POINTS: Toxic hepatitis due to losartan is very rare, despite widespread use of the drug.A high index of suspicion for drug-induced liver injury (DILI) should be maintained while other diagnoses are carefully excluded.Monitoring the use of the offending drug is crucial, since DILI recurrence is associated with worse prognosis.
