Bisphenol A (BPA) exposure has become one of the most common environmental chemical exposures in humans. There is growing evidence regarding an association between BPA exposure, hypertension, and cardiovascular diseases (CVD). If BPA exposure is indeed associated with raised blood pressure and CVD, it would be a major public health problem. Therefore, we reviewed the epidemiological, laboratory, and clinical trial evidence for an association between BPA exposure, CVD, and hypertension, and discussed the possible mechanisms in this article. Cross-sectional studies in various ethnicities suggested a possible association between BPA exposure and hypertension; this association was supported by a panel study and a randomized clinical trial. Despite the discordance among cross-sectional studies about an association between BPA exposure and CVD, a longitudinal study shows that BPA exposure is a risk factor for CVD. The effects of BPA exposure such as endocrinal disturbance, induction of oxidative stress and inflammation, epigenetic change, and links with other chronic diseases may highlight a possible mechanism between BPA exposure, CVD, and hypertension. To clarify the causal relationship, well-designed studies are needed in the future.

Discrepant incidence has been reported regarding the incidence of herb-induced liver injury (HILI). To address the growing worldwide concern of HILI, we evaluated the risk of HILI in a nationwide prospective study. Between April 2013 and January 2016, 1001 inpatients (360 males and 641 females) from 10 tertiary hospitals throughout South Korea were treated with herbal drugs and had their liver enzymes periodically measured. A total of six patients met the criteria for HILI with RUCAM scores ranging from 4 to 7. All these participants were women and developed the hepatocellular type of HILI. One HILI participant met the criteria for Hy’s law; however, none of six cases presented clinical symptoms related to liver injury. This is the first nationwide prospective study that estimated the extent of the incidence of HILI [total: 0.60%, 95% confidence interval (CI) 0.12–1.08; women: 0.95%, 95% CI 0.19–1.68] and described its features in hospitalized participants.Electronic supplementary materialThe online version of this article (doi:10.1007/s00204-017-2007-9) contains supplementary material, which is available to authorized users.
