Hypertensive crisis with 2 target organ impairment induced by glycyrrhizin: A case report

AbstractRationale:Glycyrrhizin is the main active component of licorice. Licorice and glycyrrhizin induced hypertension has been widely reported, yet licorice and glycyrrhizin induced hypertensive crisis has been rarely known.Patient concerns:The case of this report was a 47-year-old woman, who took 225 mg of glycyrrhizin daily for 3 years due to primary biliary cholangitis. She was found to have a dramatically elevated blood pressure of about 230/110 mmHg without a history of hypertension and was referred to the emergency department.Diagnoses:Hypokalemia, hypertensive retinopathy, and nephropathy were found during the following work-up. Since no other risk factors of hypertension were identified, she was suspected to have glycyrrhizin induced pseudo-hyperaldosteronism.Interventions:Glycyrrhizin was discontinued. Intravenous sodium nitroprusside was used during the first few days. Nifedipine and irbesartan were taken after discharge, and the dosage was reduced gradually under supervision.Outcomes:She stopped all the anti-hypertensive drugs 6 months since glycyrrhizin was stopped. Her blood pressure was about 110/60 mmHg after repetitive measurement. Her serum potassium and urine albumin/creatinine ratio were also normalized.Lessons:Licorice and glycyrrhizin induced hypertension due to pseudo-hyperaldosteronism has been widely reported, yet only 3 cases reported that excessive consumption of licorice could lead to hypertensive emergencies. This is the first case that gly...
