Cardiovascular toxicity of immune checkpoint inhibitors in cancer patients: A review when cardiology meets immuno-oncology

Publication date: Available online 20 August 2019Source: Journal of the Formosan Medical AssociationAuthor(s): Dong-Yi Chen, Wen-Kuan Huang, Victor Chien-Chia Wu, Wen-Cheng Chang, Jen-Shi Chen, Cheng-Keng Chuang, Pao-Hsien ChuImmune checkpoint inhibitors (ICIs) are a novel treatment option for cancer therapy, which help direct the immune system to recognize and target cancer cells. ICIs have been shown to provide significant mortality benefits for cancer patients, but they are also associated with immune-mediated toxicity. Unlike most immune-related adverse events, which are a common occurrence, reversible and can be treated effectively with glucocorticoid therapy, ICI-associated cardiotoxicities are uncommon, with serious complications and a relatively high mortality even when treated with glucocorticoids. ICI-associated cardiotoxicity can manifest in various ways, including myocarditis, arrhythmias and conduction disease, pericardial disease, myocardial infarction, non-inflammatory cardiomyocyte dysfunction, and even Takotsubo-like cardiomyopathy. The present review summarizes the current understanding of ICI-associated cardiotoxicities, examining the epidemiology and timing of onset, as well as their clinical presentation, diagnostic modalities, pathophysiology, clinical management and outcomes. Although the literature describing ICI-associated cardiotoxicity remains limited to case reports, case series and early clinical trials, strategies for the surveillance, diagnosis ...

However, the clinical use of zinc(II) complexes is hampered by hydrolytic insolubility and poor bioavailability and their anticancer mechanisms remain unclear. Here, we investigated the efficacy and mechanism of action of a polyvinylpyrrolidone (PVP-k30)-based solid dispersion of Zn(II)-curc...

HPV DNA detection in urine samples of women: "An efficacious and accurate alternative to cervical samples?" Expert Rev Anti Infect Ther. 2019 Sep 13;: Authors: Pattyn J, Van Keer S, Téblick L, Van Damme P, Vorsters A Abstract Cervical cancers are caused by persistent human papillomavirus (HPV) infections [1]. To date, HPV DNA testing using clinician-obtained cervical cells is the reference for identifying cervical infection. However, great interest has been shown for the use of self-sampling methods to detect HPV [2]. One method for self-sampling to be considered is the collection of f...

ConclusionsPRDR radiation therapy with capecitabine were well tolerated and effective method for treating patients with recurrent breast cancer. Prospective studies are necessary to compare side effects and efficacy with conventional dose rate re-irradiation, as well as, to evaluate the potential role for capecitabine in the recurrent setting.

Abstract Two highly selective OFF-ON isomer fluorescent probes (1 and 2) for homo-/cysteine were designed and synthesized. The pyrene modified tetraphenylethylene derivative with AIE was used as luminescent group while maleimide was used as recognition group. These two isomer probes were found to be nearly nonfluorescent when treated with GSH. However, upon interaction with Cys or Hcy, the fluorescence was enhanced by 2000 folds in a wide pH range from 3 to 10. Experimental results and DFT calculation have demonstrated that the fluorescence OFF-ON switch of such thiol probes is resulted from the termination of the...

vac D Abstract Metabolomics generate a profile of small molecules from plant extracts, which could be directly responsible for bioactivity effects. Using dry-column flash chromatography enabled a rapid and inexpensive method for the very efficient separation of plant extract with a high resolution. This separation method coupled to NMR and FTIR-based metabolomics is applied to identify bioactive natural products. OPLS multivariate analysis method, was used for correlation the chemical composition of the plant extracts, Amphoricarpos autariatus, with the results of cytotoxic activity against Human cervical adenocar...

Abstract CA125/MUC16 is an ovarian tumor cell marker widely used as a biomarker in epithelial ovarian carcinoma. CA125/MUC16 is also used for evaluation of the ROMA (Risk of Ovarian Malignancy Algorithm) value. In this work, a Surface Plasmon Resonance Imaging (SPRI) biosensor for circulating CA125/MUC16 has been developed. The anti-MUC16 antibody was attached to a gold chip via a cysteamine linker. The EDS/NHS protocol was used for the covalent attachment of the antibody. The developed biosensor is specific for CA125/MUC16, and exhibits good recovery and acceptable precision. Its linear response range (2.2-150 U/...

Publication date: April 2018 Source:Clinica Chimica Acta, Volume 479 Author(s): Zhe Chen, Lu He, Lanfang Li, Linxi Chen The P2X7 purinergic receptor, a calcium permeable cationic channel, is activated by extracellular ATP. Most studies show that P2X7 receptor plays an important role in the nervous system diseases, immune response, osteoporosis and cancer. Mounting evidence indicates that P2X7 receptor is also associated with cardiovascular disease. For example, the P2X7 receptor activated by ATP can attenuate myocardial ischemia-reperfusion injury. By contrast, inhibition of P2X7 receptor decreases arrhythmia after myocar...
