Fluoroquinolones and the Risk of Aortopathy: A Systematic Review and Meta-Analysis

Recent studies have raised concerns that fluoroquinolone use is associated with an increased risk of aortopathy, including aortic aneurysm with and without dissection.We performed a meta-analysis with a comprehensive literature review to further investigate this association.This analysis was conducted per PRISMA guidelines. PubMed, Cochrane Library, ClinicalTrials.gov, Embase, Web of Science, and Google Scholar were searched for studies that included adult patients (age18 years) exposed to fluoroquinolones or control antibiotics (amoxicillin/any other antibiotic) for urinary tract infection or pneumonia with a primary outcome of aortic aneurysm or dissection. Heterogeneity was calculated using Q statistic IA total of 6 studies-comprised of 59% males-were included in our analysis, which showed an increased combined risk of development of aortic aneurysm and aortic dissection with quinolone exposure when compared with controls (relative risk [RR] = 2.11; 95% CI, 1.62 - 2.75; ICompared to other antibiotics, the use of fluoroquinolones was associated with a significantly higher risk of aortic aneurysm and dissection combined.
