UPDATE: A few months after this article was posted, the work by Baylor researchers has begun to have international impact. The use of ciprofloxacin and other antibiotics of the class of fluoroquinolones may be associated with disruption of the normal functions of connective tissue, including tendon rupture, tendonitis and retinal detachment. These observations reported in a number of journals resulted in the drugs currently having a black box warning physicians and patients of the potential deleterious side effects. The endothelium, the thin layer of cells that line our arteries and veins, is like a gatekeeper, controlling the movement of materials into and out of the bloodstream. Endothelial cells are held tightly together by specialized proteins that function like strong ropes (red) and others that act like cement (blue). NIH Image Gallery “A natural tissue to worry about is the aorta, a blood vessel that relies heavily on having a sound connective tissue component – called the extracellular matrix – to maintain its integrity,” said first author Dr. Le Maire, director of research in the division of cardiothoracic surgery, vice-chair for research and professor of surgery and of molecular physiology and biophysics at Baylor College of Medicine. Two retrospective clinical studies looked at the possible association between fluoroquinolones and cardiovascular problems. “They found that patients who received fluoroquinolones had a higher risk for aneurysms (formation of balloon-like areas in the aorta that weaken the integrity of the vessel), ruptures or dissections (tears in the wall) than patients who did not receive the antibiotics. The fluoroquinolone antibiotics are important drugs indeed – ciprofloxacin is probably the most famous of the bunch, but there’s a whole series of them, and they’re widely used for serious bacterial infections. (I last wrote about them here, with the various arguments about how they were developed in the first place). But for many years now, it’s been increasingly clear that this class of drugs can have some very unwelcome effects in some patients. The most prominent of these is tendon damage, which often showing up as problems with the Achilles tendon, up to outright rupture even months after drug treatment. Other muscle and connective tissue effects have been seen, as well as CNS effects and others. Over the years, the drugs have picked up black-box warnings for these effects, which seems entirely appropriate. Any theory has to take into account the fact that the great majority of patients seem tolerate the drugs pretty well, but that suggests that a better knowledge of the mechanism might let you pick out which people shouldn’t take them in the first place. This article at is a good summary of current research in the area. Buy cheap ventolin Zoloft dose too low Lasix with potassium Key Words adverse effects, tendinitis, tendon rupture. Commonly used fluoroquinolones include ciprofloxacin, levofloxacin, pefloxacin, and norfloxacin. Abstract. Fluoroquinolone use is associated with the development of tendinopathy, most commonly affecting the Achilles tendon. Here we present the first report. Gareth Gillespie and Sarah Baggot highlight the risk of tendon ruptures as a complication of ciprofloxacin. The antibiotic ciprofloxacin is widely used in. Objectives Fluoroquinolone-associated tendon ruptures are a recognised complication, but other severe collagen-associated adverse events may also be possible. Our objectives were to confirm the association of fluoroquinolones and tendon rupture, to clarify the potential association of fluoroquinolones and retinal detachment, and to test for a potentially lethal association between fluoroquinolones and aortic aneurysms. Participants Older adults turning 65 years between April 1 1997 and March 31 2012 were followed until primary outcome, death, or end of follow-up (March 31 2014). Fluoroquinolone prescriptions were measured as a time-varying covariate, with patients considered at risk during and for 30 days following a treatment course. Results Among the 1 744 360 eligible patients, 657 950 (38%) received at least one fluoroquinolone during follow-up, amounting to 22 380 515 days of treatment. The patients experienced 37 338 (2.1%) tendon ruptures, 3246 (0.2%) retinal detachments, and 18 391 (1.1%) aortic aneurysms. Severe collagen-associated adverse events were more common during fluoroquinolone treatment than control periods, including tendon ruptures (0.82 vs 0.26/100-person years, p This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial. A couple of weeks ago, I got sick and self-medicated myself for two days with a course of ciprofloxacin (or Cipro) until I got a chance to talk to my primary physician. She agreed with my tentative diagnosis and prescribed a full course of Cipro. In fact, whenever the family travels on vacation, we pack it in case we get a case of “turista.” I viewed it as necessary and commonplace as packing some ibuprofen for pain. So I was surprised when my doctor cautioned me against strenuous exercise because a major side effect has been recently identified: tendinitis, and worse: tendon rupture. Having gone through the agony of Achilles tendon rupture during a marathon race, and surgery for a ruptured biceps tendon, her warning put the fear of God in me. They are one of the most commonly prescribed classes of antibiotics. Indeed, when I got the Cipro bottle, the first thing that tumbled out of the package was a warning about tendon problems. The reason for their popularity with physicians and patients alike is their broad-spectrum anti-bacterial activity and their high tissue distribution. These drugs are generally well-tolerated, and adverse reactions are relatively uncommon; nonetheless, if they occur, they are pretty unpleasant. Fluoroquinolones were reported to cause dysglycemias (hyper and hypo-glycymia), cardiac arrhythmias, neuropsychiatric events, corneal perforation (topical application only, and by another fluor ofloxacin, not cipro), most important to exercise fanatics: tendinitis and tendon rupture.
