RT Journal Article SR Electronic T1 Fluoroquinolone-induced serious, persistent, multisymptom adverse effects JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr2015209821 DO 10.1136/bcr-2015-209821 VO 2015 A1 Golomb, Beatrice Alexandra A1 Koslik, Hayley Jean A1 Redd, Alan J YR 2015 UL http://casereports.bmj.com/content/2015/bcr-2015-209821.abstract AB We present a case series of four previously healthy, employed adults without significant prior medical history in each of whom symptoms developed while on fluoroquinolones (FQs), with progression that continued following discontinuation evolving to a severe, disabling multisymptom profile variably involving tendinopathy, muscle weakness, peripheral neuropathy, autonomic dysfunction, sleep disorder, cognitive dysfunction and psychiatric disturbance. Physicians and patients should be alert to the potential for FQ-induced severe disabling multisymptom pathology that may persist and progress following FQ use. Known induction by FQs of delayed mitochondrial toxicity provides a compatible mechanism, with symptom profiles (and documented mechanisms of FQ toxicity) compatible with the hypothesis of an exposure-induced mitochondrial neurogastrointestinal encephalomyopathy.
