RESUMO
RATIONALE: Sacubitril/valsartan (Entresto) is the first drug approved for the treatment of symptomatic chronic heart failure with reduced ejection fraction in adult patients. There have been no reports of hepatotoxicity secondary to sacubitril/valsartan administration. Here, we report the first case of severe liver injury caused by sacubitril/valsartan. PATIENT CONCERNS: A 90-year-old female patient taking sacubitril/valsartan was admitted due to chronic heart failure. Subsequently, the patient developed serious liver injury with increased hepatic transaminases. DIAGNOSIS: Drug-induced liver injury, sacubitril/valsartan-related. No liver injury caused by other reasons was observed after thorough examination. After the withdrawal of sacubitril/valsartan, the liver function of the patient gradually returned to normal. INTERVENTIONS: We chose general liver protection methods to improve her hepatic function, including magnesium isoglycyrrhizinate at 100 mg daily and polyene phosphatidylcholine capsules at 456 mg 3 times daily. We consulted with a hepatologist to discuss the best plan for her treatment. The last, we stopped sacubitril/valsartan. OUTCOMES: After the withdrawal of sacubitril/valsartan, the liver function of the patient gradually returned to normal. LESSONS: Sacubitril/valsartan-induced liver injury is very rare. Clinicians should pay particular attention to the possibility of hepatotoxicity during sacubitril/valsartan treatment.
