Abiraterone, an oral androgen biosynthesis inhibitor, has been reported to increase the risk of statin-associated muscle toxicity through inhibition of hepatic transporters involved in statin disposition, potentially increasing systemic statin exposure. Despite this proposed mechanism, direct pharmacokinetic evidence of this interaction in patients experiencing this adverse event has not previously been reported. We report a case of rhabdomyolysis complicated by acute kidney injury (AKI) in a patient on long-term rosuvastatin therapy following initiation of abiraterone for the treatment of prostate cancer. Quantitative plasma analysis using liquid chromatography-mass spectrometry demonstrated a rosuvastatin concentration substantially higher than concentrations observed with therapeutic dosing and consistent with previously reported toxic concentrations. This case provides pharmacokinetic support for a clinically significant abiraterone-rosuvastatin drug interaction and underscores the importance of medication review, early recognition of muscle toxicity, and consideration of alternative lipid-lowering strategies to preserve atherosclerotic cardiovascular disease (ASCVD) risk reduction in patients being treated with abiraterone.

High Lp(a) levels are recognized as a causal and independent risk factor for atherosclerotic cardiovascular disease (ASCVD) and are an important contributor to residual ASCVD risk. International guidelines reflect the importance of measuring Lp(a) at least once in all adults as an important component of ASCVD risk assessment and management.</p><p><strong>Objective: </strong>This document aims to summarize the guidelines recommending universal measurement of Lp(a), including the associated risk thresholds that can be used to identify individuals with higher ASCVD risk based on their plasma Lp(a) concentrations. Additionally, direction on managing patients with high Lp(a) is provided, as well as information on therapies in development to lower Lp(a).</p><p><strong>Methods: </strong>The most recent statements and updates from international societies were reviewed for guidance on Lp(a) measurement and management, with particular attention to the 2026 American College of Cardiology/American Heart Association multisociety guideline on the management of dyslipidemia. Information on pharmaceutical agents that are in late stages of development for targeted lowering of Lp(a) is also summarized.</p><p><strong>Results: </strong>The synthesis of existing information on how to manage patients with elevated Lp(a) reinforces the importance of measurement of Lp(a) in all adults at least once in their lifetime and provides direction on when repeated measurement may be warranted. In the absence of available drugs to specifically and effectively lower Lp(a), management of modifiable risk factors is encouraged. Furthermore, the large contribution of genetics to the determination of Lp(a) levels underscores the importance of cascade screening of family members to identify at-risk individuals.</p><p><strong>Conclusion: </strong>There is broad recognition of the importance of measuring Lp(a) at least once in all adults, owing to the recognized role of elevated Lp(a) as an important ASCVD risk enhancer. At present, this information is useful in risk stratification and can guide optimal management of ASCVD risk in patients. However, the potential for new Lp(a) lowering therapies to specifically and substantially reduce Lp(a) levels underscores the importance of Lp(a) measurement in all adults.</p>","PeriodicalId":15392,"journal":{"name":"Journal of clinical lipidology","volume":" ","pages":""},"PeriodicalIF":6.9,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149182203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
