Analysis of clinical factors associated with Kampo formula-induced pseudoaldosteronism based on self-reported information from the Japanese Adverse Drug Event Report database. PLoS One 2024; 19:e0296450. [PMID: 38165850 PMCID: PMC10760746 DOI: 10.1371/journal.pone.0296450] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 12/10/2023] [Indexed: 01/04/2024] Open
Abstract
Drug-induced pseudoaldosteronism is a typical adverse effect of Kampo formulas. Previous research described the potential risks of Kampo formula-linked pseudoaldosteronism. However, few studies assessed the risk factors using a real-world database and a data-mining approach. Using the Japanese Adverse Drug Event Report database, we extracted pseudoaldosteronism reports for 148 Kampo formulas covered by Japanese national health insurance. Adverse events were decided according to the preferred terminology of the Medical Dictionary for Regulatory Activities/Japanese version 25.1. We calculated reporting odds ratio (RORs) and identified Kampo formulas as suspected causes of pseudoaldosteronism. Moreover, we evaluated clinical factors associated with Kampo formula-induced pseudoaldosteronism via logistic regression. From April 2004 to November 2022, 6334 adverse events related to the Kampo formulas were reported. We selected 2471 reports containing complete clinical data, including 210 reports on pseudoaldosteronism. In the pseudoaldosteronism group, 69.0% of patients were female, and 85.2% were ≥70 years old. The formulas most commonly associated with pseudoaldosteronism were Shakuyakukanzoto, Yokukansan, and Ryokeijutsukanto (ROR [95% confidence interval {CI}] = 18.3 [13.0-25.9], 8.1 [5.4-12.0], and 5.5 [1.4-21.9], respectively). Logistic analysis identified female sex (odds ratio [OR] [95% CI] = 1.7 [1.2-2.6]; P = 0.006), older age (≥70, 5.0 [3.2-7.8]; P < 0.001), low body weight (<50 kg, 2.2 [1.5-3.2]; P < 0.001), diuretics usage (2.1 [1.3-4.8]; P = 0.004), hypertension (1.6 [1.1-2.4]; P = 0.014), and dementia (7.0 [4.2-11.6]; P < 0.001) as pseudoaldosteronism-related factors. Additionally, the daily Glycyrrhiza dose (OR = 2.1 [1.9-2.3]; P < 0.001) and duration of administration (>14 days, OR = 2.8 [1.7-4.5]; P < 0.001) were associated with adverse events. We did not observe an interaction between aging and hypertension. Careful follow-up is warranted during long-term Glycyrrhiza-containing Kampo formula use in patients with multiple clinical factors for pseudoaldosteronism.

Abstract
AIM Behavioral and psychological symptoms and delirium frequently occur in hospitalized older patients with pneumonia and are associated with longer hospital stays. Yokukan-San (YKS, traditional Japanese [Kampo] medicine) and antipsychotics are often used to treat delirium and behavioral and psychological symptoms in Japan. Hence, this study aimed to assess the effectiveness and safety of the co-administration of YKS with atypical antipsychotics in older patients with pneumonia. METHODS We used the Japanese Diagnosis Procedure Combination inpatient database to retrospectively identify older patients (≥65 years) hospitalized for pneumonia who received antipsychotics within 3 days of hospitalization. The patients were divided into two groups: those who received atypical antipsychotics alone (control group) and those who received both atypical antipsychotics and YKS (YKS group). We compared length of hospital stay, in-hospital mortality, bone fractures, and administration of potassium products between the two groups using propensity score overlap weighting. RESULT We identified 4789 patients in the YKS group and 61 641 in the control group. After propensity score overlap weighting, length of hospital stay was statistically significantly shorter in the YKS group (percentage difference -3.0%; 95% confidence interval -5.8% to -0.3%). The proportion of patients who received potassium products was higher in the YKS group (odds ratio 1.34; 95% confidence interval 1.15-1.55). In-hospital death and bone fractures were not significantly different. CONCLUSION Co-administration of YKS with atypical antipsychotics could be a reasonable treatment option for hospitalized older patients with pneumonia and aggressive psychiatric symptoms.

Eur Heart J Case Rep 2023; 7:ytad398. [PMID: 37662578 PMCID: PMC10473849 DOI: 10.1093/ehjcr/ytad398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 07/24/2023] [Accepted: 08/14/2023] [Indexed: 09/05/2023]
Abstract
Background Excessive liquorice ingestion sometimes causes pseudoaldosteronism. The association between liquorice-induced pseudoaldosteronism and acute heart failure has not been well described. Case summary An 89-year-old woman was referred to the hospital due to muscle weakness with rhabdomyolysis and severe hypokalaemia. The electrocardiogram in the emergency department revealed pulseless ventricular tachycardia, thus, emergent defibrillation was delivered. Laboratory findings revealed severe hypokalaemia with metabolic alkalosis. Plasma renin activity and serum aldosterone were highly suppressed. Her medications included herbal medicines containing a great amount of liquorice. The patient was diagnosed with pseudoaldosteronism caused by liquorice over-ingestion. She developed acute pulmonary oedema with unexpected left ventricular (LV) dysfunction after the peak out of creatine kinase. She was managed with acute heart failure therapy, as well as optimal medical therapy. She accidentally developed an acute embolic stroke but fully recovered due to emergent thrombolytic therapy. Cardiac magnetic resonance imaging revealed banding late gadolinium enhancement in the basal-mid segments, which was inconsistent with takotsubo cardiomyopathy. As time passed, LV function unexpectedly improved, and congestive heart failure was completely compensated. Discussion Liquorice contains glycyrrhetinic acid that inhibits 11βHSD2. This invites the over-activation of mineralocorticoid receptors by cortisol in the kidneys and eventually causes hypokalaemia and hypertension. Acute heart failure caused by excessive liquorice ingestion is scarcely described. The triggering factors for LV dysfunction and acute congestive heart failure remain unclear. Rhabdomyolysis could affect massive catecholamine release and cause LV dysfunction.

Abstract
Aim Yokukansan is a Japanese herbal medicine used in psychiatry to treat behavioral and psychological symptoms of dementia and other psychiatric symptoms. However, the glycyrrhizic acid included in this medicine can cause pseudoaldosteronism and hypokalemia. We aimed to identify the risk factors for hypokalemia due to yokukansan. Methods A retrospective cohort study was conducted on patients previously treated with yokukansan. The risk factors were determined by comparing the hypokalemia group with the non-hypokalemia group for each parameter. Results This study included 304 patients who received yokukansan treatment between April 2009 and March 2019. We found that 17.4% (n = 53) of the patients experienced yokukansan-induced hypokalemia. Risk factors detected as significantly different between patients with and without yokukansan-associated hypokalemia were low serum potassium concentration before yokukansan administration, dose 7.5 g /day or more, and dementia. Hypokalemia occurred earlier in patients with low albumin, low potassium, and dementia. Conclusion It is necessary to pay attention to hypokalemia onset when administering yokukansan at 7.5 g or more to patients with low potassium levels and dementia. Our findings suggest that potassium levels must be checked early after yokukansan administration, especially in patients with low albumin, low potassium, and dementia.

Abstract
Chronic urticaria (CU) is a pathologic condition marked by the emergence of wheals, angioedema, or both for more than six weeks. The improper activation and degranulation of mast cells is the triggering event, which results in the production of various mediators such as histamine, leukotrienes, PAF, chemokines, and cytokines. Antihistamines are currently the most common pharmacological treatment for urticaria, but corticosteroids and monoclonal antibodies can also be employed. Patients who have been taking antihistamines for a long time are often looking for alternatives. Whole plants, portions of plants, or single extracted active compounds are all used in phytomedicine. Plant elements are frequently combined to create formulations that can be utilized to treat a variety of pathological disorders. Anti-inflammatory and/or anti-allergic properties are found in several herbs regularly used in herbal formulations. Antioxidant properties are also present in some of the constituents. Exogenous antioxidants have been shown to improve the progression of autoimmune disorders in numerous studies. The aim of this review is to identify the most common herbs used to treat chronic urticaria, and to characterize their efficacy, mechanisms of action, and risk/benefit ratio in comparison to western treatment, and also to find less often used formulations and assess their therapeutic efficacy, safety profile, and potential for wider use.

Abstract
Individual differences in gut microbiota can affect the pharmacokinetics of drugs. Yokukansan is a traditional Japanese kampo medicine used to treat peripheral symptoms of dementia and delirium. A study examining the pharmacokinetics of the components of yokukansan reported large individual differences in the pharmacokinetics of glycyrrhizic acid (GL). It is known that GL is metabolized by intestinal bacteria to glycyrrhetinic acid (GA), which is absorbed in the gastrointestinal tract. Thus, the gut microbiota may affect GL pharmacokinetics. We aimed to clarify the relationship between the gut microbiota composition and pharmacokinetics of GL in yokukansan. Mice were orally administered yokukansan, following the administration of various antibiotics, and the plasma concentration of GA and composition of gut microbiota were measured. The GA plasma concentration was low in mice treated with amoxicillin and vancomycin. The composition of gut microbiota revealed a different pattern from that of the control group. Mice with low plasma levels of GA had lower levels of the phylum Bacteroides and Firmicutes. Additionally, bacteria, such as those belonging to the genera Parabaceroides, Bacteroides, Ruminococcus and an unknown genus in families Lachnospiraceae and Ruminococcaceae, exerted positive correlations between the gene copies and plasma GA levels. These bacteria may contribute to the absorption of GA in the gastrointestinal tract, and multiple bacteria may be involved in GL pharmacokinetics. The pharmacokinetics of GL may be predicted by evaluating the composition of gut bacteria, rather than by evaluating the amount of a single bacterium.

Abstract
Licorice, the dried root or stolon of Glycyrrhiza glabra or G. ularensis, is commonly used worldwide as a food sweetener or crude drug. Its major ingredient is glycyrrhizin. Hypokalemia or pseudoaldosteronism (PsA) is one of the most frequent side effects of licorice intake. Glycyrrhizin metabolites inhibit type 2 11β-hydroxysteroid dehydrogenase (11βHSD2), which decomposes cortisol into inactive cortisone in the distal nephron, thereby inducing mineralocorticoid receptor activity. Among the several reported glycyrrhizin-metabolites, 18β-glycyrrhetyl-3-O-sulfate is the major compound found in humans after licorice consumption, followed by glycyrrhetinic acid. These metabolites are highly bound to albumin in blood circulation and are predominantly excreted into bile via multidrug resistance-associated protein 2 (Mrp2). High dosage and long-term use of licorice are constitutional risk factors for PsA. Orally administered glycyrrhizin is effectively hydrolyzed to glycyrrhetinic acid by the intestinal bacteria in constipated patients, which enhances the bioavailability of glycyrrhizin metabolites. Under hypoalbuminemic conditions, the unbound metabolite fractions can reach 11βHSD2 at the distal nephron. Hyper direct-bilirubin could be a surrogate marker of Mrp2 dysfunction, which results in metabolite accumulation. Older age is associated with reduced 11βHSD2 function, and several concomitant medications, such as diuretics, have been reported to affect the phenotype. This review summarizes several factors related to licorice-induced PsA, including daily dosage, long-term use, constipation, hypoalbuminemia, hyper direct-bilirubin, older age, and concomitant medications.

Abstract
Background: Dementia is a global health concern, causing serious health and socioeconomic burdens with population aging. The associated symptoms of dementia, called behavioral and psychological symptoms of dementia (BPSD), are factors contributing to the socioeconomic burden of dementia. Recently, herbal medicine (HM) has attracted attention as a potential complementary therapy for BPSD. Therefore, this systematic review was aimed at analyzing the effectiveness (or efficacy), safety, and research status of HM in BPSD management through a comprehensive review. Methods: Thirteen electronic databases were searched comprehensively. Related clinical studies published until December 28, 2020, were collected. The methodological quality was evaluated using tools such as the Cochrane Collaboration’s risk of bias tool according to the study design. The effectiveness (or efficacy) was analyzed for randomized controlled trials (RCTs) only, and when sufficient homogeneity was assured, effect estimates were presented as mean difference (MD) and risk ratio (RR), with 95% confidence interval (CIs), through a meta-analysis. Results: A total of 52 clinical studies, including 36 RCTs, were included in this review. As an adjunctive therapy, HM showed statistically significant benefits in BPSD severity assessed by the Behavior Pathology in Alzheimer’s Disease Rating Scale (combined with psychotropic drugs: MD = −3.48, 95% CI: −3.96 to −2.99; with anti-dementia drugs: MD = −2.81, 95% CI: −3.17 to −2.45) and Neuropsychiatric Inventory (with anti-dementia drugs: MD = −3.23, 95% CI: −4.06 to −2.40). Adverse events were significantly less frequent in the HM group (RR = 0.50; 95% CI: 0.28 to 0.88). However, the methodological quality of the RCTs included in this systematic review was not optimal overall. Conclusion: According to the findings of this review, HM may be associated with additional benefits in BPSD treatment, particularly when used as an adjunct to conventional medications, including psychotropic and anti-dementia drugs. However, considering the methodological quality of the included RCTs, this clinical evidence is not robust. Nevertheless, dementia is a global health concern, and considering the limitations of conventional psychotropic drugs for BPSD, a major cause of the disease burden, HM appears to be a promising complementary therapy that warrants further research.

Abstract
AIM Rapid eye movement sleep behaviour disorder (RBD) is characterized by abnormal behaviours accordant with nightmares during rapid eye movement sleep and is considered a prodromal marker of dementia with Lewy body. Most common in the elderly population, RBD is generally treated with clonazepam (CZP), a long-term acting benzodiazepine antiepileptic. As such, alternative drugs for RBD are urgently needed to minimize the adverse effects peculiar to benzodiazepines. The efficacy of yokukansan (YKS), a traditional Japanese herbal medicine, on RBD was initially reported by Shinno et al. in 2008. However, no study has compared YKS with CZP. Therefore, this study aimed to clarify the possibility of using YKS as an alternative to CZP. METHODS This was a retrospective cohort study conducted at Jikei University Affiliated Hospital. The subjects were selected from 36 outpatients who had been diagnosed with RBD based on the International Classification of Sleep Disorders, third edition. Of the 23 who met the inclusion criteria but not the exclusion criteria, 11 were treated with YKS monotherapy, and 12 were treated with CZP monotherapy. The primary outcome was the total score on the Japanese version of the Rapid Eye Movement Sleep Behaviour Disorder Questionnaire (RBDQ-JP), and the secondary outcomes were the scores from the eight-item Short-Form Health Survey and factors 1 and 2 of the RBDQ-JP. RESULTS The mean total RBDQ-JP score significantly improved from 52.5 to 21.7 (P = 0.002) after treatment with YKS (mean dosage: 3.0 g/day), which was similar to the change after CZP treatment (from 43.8 to 21.3). On RBDQ-JP factor 1 (dream content), the mean score on five of six items significantly improved after treatment with YKS. There was no significant change in Short-Form Health Survey scores after treatment with either drug. Potassium concentrations were within the normal range in patients treated with YKS. CONCLUSIONS The present results suggest that a small amount of YKS may be an alternative to CZP for RBD, without remarkable adverse events. Further study is needed to prospectively clarify the efficacy and safety of YKS in more detail.

Abstract
Objective: The development of pseudoaldosteronism is shown to be mainly associated with four factors: daily dose of glycyrrhiza (licorice), duration of glycyrrhiza use, body size, and age. Recently, direct bilirubinemia and hypoalbuminemia are newly reported as possible factors that trigger pseudoaldosteronism due to glycyrrhiza ingestion. Pseudoaldosteronism occurs in the presence of combinations of these factors; therefore, the importance of each factor on the tolerance to glycyrrhiza loading is still unclear. Methods: In seven patients (63-78 years old, six women) who developed pseudoaldosteronism due to ingestion of glycyrrhiza-containing Kampo extract in their clinic, serum albumin and direct bilirubin (D-bil) levels were investigated. In six women, the authors evaluated the correlations between daily dose of glycyrrhiza ingested and each factor: age, height, weight, body mass index, body surface area (BSA), and duration of ingestion (Pearson's correlation coefficient). Results: No patients had abnormal levels of serum albumin or D-bil around the time of the onset. In six women, the highest correlation coefficient was observed between BSA and the glycyrrhiza dose in Kampo extract at the onset of pseudoaldosteronism. Conclusions: The findings suggested that in elderly women, BSA should be considered first as a factor for predicting the development of pseudoaldosteronism.

Bioactive Candy: Effects of Licorice on the Cardiovascular System. Foods 2019; 8:foods8100495. [PMID: 31615045 PMCID: PMC6836258 DOI: 10.3390/foods8100495] [Citation(s) in RCA: 45] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Revised: 10/07/2019] [Accepted: 10/09/2019] [Indexed: 12/15/2022] Open
Abstract
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.

Abstract
Patients with uncontrolled hypertension are at risk for cardiovascular complications. The majority of them suffers from unidentified forms of hypertension and a fraction has so-called secondary hypertension with an identifiable cause. The patient's medications, its use of certain herbal supplements and over-the-counter agents represent potential causal factors for secondary hypertension that are often overlooked. The current review focuses on drugs that are likely to elevate blood pressure by affecting the human endocrine system at the level of steroid synthesis or metabolism, mineralocorticoid receptor activity, or by affecting the catecholaminergic system. Drugs with known adverse effects but where benefits outweigh their risks, drug candidates and market withdrawals are reviewed. Finally, potential therapeutic strategies are discussed.
