Levofloxacin-associated Encephalopathy with Severe Hyperventilation

Fluoroquinolone-Associated Movement Disorder: A Literature Review

BACKGROUND

Fluoroquinolones (FQNs) are related to several central nervous system side effects. This review aims to evaluate the clinical-epidemiological profile, pathophysiological mechanisms, and management of FQNs-associated movement disorders (MDs).

METHODS

Two reviewers identified and assessed relevant reports in six databases without language restriction between 1988 and 2022.

RESULTS

A total of 45 reports containing 51 cases who developed MDs secondary to FQNs were reported. The MDs included 25 myoclonus, 13 dyskinesias, 7 dystonias, 2 cerebellar syndromes, 1 ataxia, 1 tic, and 2 undefined cases. The FQNs reported were ciprofloxacin, ofloxacin, gatifloxacin, moxifloxacin, levofloxacin, gemifloxacin, and pefloxacin. The mean and median age were 64.54 (SD: 15.45) and 67 years (range: 25-87 years). The predominant sex was male (54.16%). The mean and median time of MD onset were 6.02 (SD: 10.87) and 3 days (range: 1-68 days). The mean and median recovery time after MD treatment was 5.71 (SD: 9.01) and 3 days (range: 1-56 days). A complete recovery was achieved within one week of drug withdrawal in 80.95% of the patients. Overall, 95.83% of the individuals fully recovered after management.

CONCLUSIONS

Future cases need to describe the long-term follow-up of the individuals. Additionally, FQN-induced myoclonus should include electrodiagnostic studies.

Clinical Efficacy and Safety Analysis of Levofloxacin for the Prevention of Infection after Traumatic Osteoarthrosis and Internal Fixation: Systematic Review and Meta-Analysis

Objective

Levofloxacin has been widely used in clinical anti-infection treatment; however, its adverse reactions to levofloxacin were also obvious in patients. Herein we aimed to systematically evaluate the clinical efficacy and safety of systemic administration of levofloxacin in the prevention of postoperative infection after traumatic osteoarthrosis and internal fixation.

Methods

PubMed, Cochrane Library, OVID, EBSCO, CNKI, VIP database, and Wanfang Database were searched from December 1993 to December 2021. Meanwhile, China ADR Information Bulletin and WHO Pharmaceutical were searched manually. Newsletter and FDA Drug Safety Newsletter, also to retrieve the Websites of Chinese, Chinese, and drug regulatory authorities; To obtain data on adverse events in children with systemic administration of levofloxacin. The literature was screened according to inclusion and exclusion criteria. The risk of bias was evaluated for the included RCT literature.

Results

There was a statistical difference in the comparison of the incidence of fever between the experimental group and the control group (OR = 2.29, 95% CI (1.75,2.98),P < 0.00001, I² = 0%, Z = 6.11); elevated white blood cell count (OR = 1.82, 95% CI (1.31,2.52),P=0.0003, I² = 0%, Z = 3.60); incidence of wound infection (OR = 2.11, 95% CI (1.54,2.90),P < 0.00001, I² = 0%, Z = 4.64); adverse drug reaction (OR = 1.82, 95% CI (1.21,2.74),P=0.004, I² = 0%, Z = 2.86).

Conclusion

In the clinical use of levofloxacin, adverse drug reactions including fever, elevated white blood cell count, and wound infection should be concerned.

A case of suspected antibiotic-associated encephalopathy in a patient undergoing long-term peritoneal dialysis

A man undergoing long-term peritoneal dialysis who had no history of mental illness suffered psychosis and auditory hallucination 2 days after clindamycin was initiated at a single dose of 0.6 g per day for pulmonary infection. His mental symptoms disappeared after clindamycin was discontinued and peritoneal dialysis was strengthened. The patient’s body temperature was mildly elevated the day before he was admitted to the hospital, and no abnormalities were observed on head and chest computed tomography imaging at admission, except for a slow rhythm on electroencephalogram. Many factors were involved in this case; antibiotic-related encephalopathy caused by clindamycin may be one factor. Physicians should carefully consider the use of antibiotics, especially in patients with end-stage renal disease.
