Abstract

The etiology of cardiomyopathies are classified into 4 main groupings (dilated, hypertrophic, restrictive, and idiopathic) and can be mechanistically caused by myocarditis, conduction abnormalities, focal direct injury, or nutritional deficiency. Based on our review of this topic, evidence suggests that echinocandin-related cardiac dysfunction is a mitochondrial drug-induced disease caused by focal direct myocyte injury. With caspofungin or anidulafungin administration into the heart via central line, exposure is likely extreme enough to induce the acute toxicity. Chronic or low-dose exposure may lead to hypertrophic cardiomyopathy; however, only acute exposures have been explored to date.

The Mycotic Research Center at the University of Mississippi Medical Center has long focused on augmenting the knowledge of antifungal drugs to maximize safety and minimize toxicity. In 2008, Drs. John D. Cleary and Kayla R. Stover embarked on a mission to determine the mechanism of toxicity that led to the black boxed warning for congestive heart failure with itraconazole, an azole antifungal.1 In the course of these endeavors, Cleary and Stover noticed that there was reason to be concerned about other antifungals based on anecdotal clinical reports of cardiac decompensation, particularly in critically ill patients. In an effort to elucidate the cardiac effects with the echinocandin antifungals (caspofungin, micafungin, and anidulafungin), Cleary and Stover initiated a series of studies. In ex vivo Langendorff models, Cleary and Stover identified decreases in cardiac function with caspofungin and anidulafungin.2 Investigators further explored these findings, evaluating cardiac-related biomarkers, electric function of the hearts, and cell structure via transmission electron microscope.3,4 Although biomarkers and electric function showed no specific findings, transmission electron microscope suggested mitochondrial damage with these two agents. Further explorations into mitochondrial effects were completed using a Clark-type electrode (abstract, publication pending).5,6 Next, Cleary and Stover evaluated whether the decreases in cardiac function that were seen in the ex vivo model would be reproduced in in vivo animal model.7 In these studies, caspofungin and anidulafungin were associated with clinically and statistically significant decreases in cardiac output; micafungin was not. Other in vitro and in vivo studies have displayed comparable results.8,9

In 2012, the first of several human case reports was published that described cardiovascular decompensation following administration of caspofungin or anidulafungin.10 Since that time, a handful of other reports have helped to substantiate the results of the previously described studies.11-13 As the number of reports have grown, the possibility that some of the echinocandins, particularly caspofungin and anidulafungin, may cause cardiac toxicity in patients receiving these agents has become increasingly recognized as a genuine concern.14 Clinicians should be aware and should diligently monitor patients, particularly critically ill patients receiving these agents via central catheter, for signs or symptoms of cardiac toxicity during therapy.
