Abstract

According to clinical studies, the use of fluoroquinolone antibacterial agents is associated with such rare, but serious adverse reactions as aortic injuries. The aim of the study was to analyse scientific literature data on the risk of aortic injury during fluoroquinolone treatment. The analytical review showed that the risk factors for fluoroquinolone-induced aortic injury are male gender, age over 45 years, underlying aortic disease, as well as smoking and associated atherosclerosis. Clinical and morphological forms of fluoroquinolone-associated aortic injuries include dilatation (aneurysm development), dissection, and rupture. The analysis of data on the association between aortic injuries and the use of most common fluoroquinolones (ciprofloxacin, levofloxacin, and moxifloxacin) showed that development of aneurysm and dissection was most often observed for levofloxacin, and least often for ciprofloxacin. The mechanism of aortic injury is due to fluoroquinolone-mediated activation of matrix metalloproteinases which damage elastic components of vascular walls, as well as reduction in lysyl oxidase expression and collagen synthesis. The ability of fluoroquinolones to form complexes with magnesium ions reduces the availability of magnesium to the cell enzyme systems, which delays synthesis of extracellular matrix structural proteins, leads to metalloproteinase activation and calcification of the vascular walls. Prevention, early detection, and timely management of the above-mentioned issues depend on the awareness of different medical specialists about the risks of aortic injury associated with the use of fluoroquinolone antibiotics.
