Fluoroquinolone-Mediated Tendinopathy and Tendon Rupture

Area of Science:

• Pharmacology
• Biomedical Engineering
• Molecular Biology

Background:

• Fluoroquinolones (FQs) are widely prescribed antibiotics with low resistance but significant side effects.
• Tendon injuries, including tendinopathy and rupture, are serious adverse effects linked to FQ use.
• The precise molecular mechanisms underlying FQ-induced tendon damage remain incompletely understood.

Purpose of the Study:

• To review the current understanding of fluoroquinolone antibiotics, their mechanisms, and side effects.
• To explore the detailed effects of FQs on tendon tissue structure, cellular function, and the extracellular matrix.
• To discuss potential preventative strategies and future research avenues for FQ-mediated tendinopathy.

Main Methods:

• Review of existing literature on fluoroquinolones and tendon biology.
• Analysis of molecular and cellular changes induced by FQs in tendon tissue.
• Discussion of in vitro and in vivo models for studying FQ effects on tendons.

Main Results:

• FQ-mediated tendinopathy and rupture are associated with altered gene expression, metabolism, and function of tendon resident cells.
• These cellular changes lead to significant alterations in the extracellular matrix composition and integrity.
• Current understanding of FQ-induced tendon damage is limited, necessitating further investigation.

Conclusions:

• FQ antibiotics pose a risk of severe tendon damage, including rupture, through complex molecular pathways.
• Future research should integrate in vitro and in vivo models, emphasizing advanced 3D in vitro systems to mimic in vivo complexity.
• A deeper understanding is crucial for developing preventative measures against FQ-induced tendinopathy.
