[Galactin-3: diagnostic and prognostic value in patients with chronic heart failure]

The role of interleukin-6 in the development of cardiovascular diseases: A review

Currently, the search and study of new biological markers that can provide early diagnosis of cardiovascular diseases, serve as a laboratory tool for assessing the effectiveness of treatment, or be used as prognostic markers and risk stratification criteria is ongoing. Our literature review indicates the potentially important diagnostic and prognostic value of assessing members of the interleukin-6 family. It is expected that further scientific and clinical studies will demonstrate the possibility of using members of the interleukin-6 family as an additional laboratory tool for the diagnosis, risk stratification and prediction of cardiovascular events in cardiac patients. It is necessary to evaluate in detail the possibilities of blockade of these interleukin-6 molecules in patients with cardiovascular diseases in vitro and in vivo.

Pentraxin-3 – a promising biological marker in heart failure: literature review

According to many studies, inflammation plays a very significant role in the pathogenesis of heart failure. Many studies have demonstrated an increase in circulating levels of inflammatory markers and cytokines such as C-reactive protein, tumor necrosis factor-a (TNF-a), and interleukins. C-reactive protein is produced in the liver in response to stimulation by various cytokines, mainly interleukin-6, and is a member of the pentraxin superfamily. Pentraxin-3, which is a long pentraxin, has a C-terminal domain of pentraxin similar to the classic short pentraxins, but differs from them in the presence of an unrelated long N-terminal domain. Various cell types can produce pentraxin-3 when exposed to primary inflammatory signals such as interleukin-1, tumor necrosis (TNF-a), oxidized low density lipoprotein, and microbial fragments (eg, lipopolysaccharide, lipoarabinomannans). Data in experimental animal models have demonstrated that pentraxin-3 can play cardioprotective and atheroprotective roles through its influence on the inflammatory process. Pentraxin-3 has been studied in several clinical protocols as a potential biomarker for cardiovascular disease.
