Objective. We aimed to estimate the risk of varied antifungal therapy with azoles causing the syndrome of acquired apparent mineralocorticoid excess (AME) in the real-world practice. Methods. First, we conducted a disproportionality analysis based on data from the FDA Adverse Event Reporting System (FAERS) database to characterize the signal differences of triazoles - related AME. Second, a systematic review was conducted, and to describe clinical features of AME cases reported in clinical practice. Results. In the FAERS database, we identified 27 cases of triazoles - AME, posaconazole [ROR=865.37; 95%CI (464.14; 1613.45)] and itraconazole [ROR=556.21; 95% (303.05; 1020.85)] significantly increased the risk of AME events, while fluconazole, voriconazole and isavuconazole did not affect any of the mineralocorticoid excess targets. 18 studies with 39 cases raised evidence of AME following posaconazole and itraconazole treatment, and another 27 cases were identified by analysis of the description of clinical features in FAERS database. The average age of 66 patients was 55.5 years (6∼87 years). AME mainly occurs in patients with posaconazole concentrations above 3 μg/mL (mean=4.4μg/mL, range 1.8∼9.5μg/mL), and is less likely to occur when levels are below 2 μg/mL (6%). The median time to event onset was 11.5 weeks, and 50% of the adverse events occurred within 3 months for posaconazole. Conclusion. The presented study supports very recent findings that posaconazole and itraconazole but not the other three azole antifungals investigated are associated with AME and the effects were dose-dependent, which allows for a dose de-escalation strategy and for substitution with fluconazole, isavuconazole or voriconazole to resolve the adverse effects.

Mineralocorticoid hypertension is characterized by increased distal renal tubular sodium reabsorption, raised body sodium content, plasma volume expansion, markedly reduced body potassium content, with a metabolic alkalosis and suppression of renin production by the juxtaglomerular cells of the kidney (and correspondingly low levels of angiotensin II). Primary aldosteronism is the most common cause of mineralocorticoid hypertension (1); less frequent causes include the rare inborn errors of adrenal steroid synthesis (11β‎-hydroxylase and 17α‎-hydroxylase deficiency), alterations in corticosteroid metabolism (syndrome of apparent mineralocorticoid excess), and constitutive activation of the epithelial sodium channel (Liddle’s syndrome).

Licorice, today chiefly utilized as a flavoring additive in tea, tobacco and candy, is one of the oldest used herbs for medicinal purposes and consists of up to 300 active compounds. The main active constituent of licorice is the prodrug glycyrrhizin, which is successively converted to 3β-monoglucuronyl-18β-glycyrrhetinic acid (3MGA) and 18β-glycyrrhetinic acid (GA) in the intestines. Despite many reported health benefits, 3MGA and GA inhibit the 11-β-hydrogenase type II enzyme (11β-HSD2) oxidizing cortisol to cortisone. Through activation of mineralocorticoid receptors, high cortisol levels induce a mild form of apparent mineralocorticoid excess in the kidney and increase systemic vascular resistance. Continuous inhibition of 11β-HSD2 related to excess licorice consumption will create a state of hypernatremia, hypokalemia and increased fluid volume, which can cause serious life-threatening complications especially in patients already suffering from cardiovascular diseases. Two recent meta-analyses of 18 and 26 studies investigating the correlation between licorice intake and blood pressure revealed statistically significant increases both in systolic (5.45 mmHg) and in diastolic blood pressure (3.19/1.74 mmHg). This review summarizes and evaluates current literature about the acute and chronic effects of licorice ingestion on the cardiovascular system with special focus on blood pressure. Starting from the molecular actions of licorice (metabolites) inside the cells, it describes how licorice intake is affecting the human body and shows the boundaries between the health benefits of licorice and possible harmful effects.
