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.

A 38-year-old male with recently diagnosed HIV and gonorrhea presented with umbilicated facial lesions and blepharoconjunctivitis of the right eye. Polymerase chain reaction test was performed of the skin were positive for Monkeypox (MPX). The patients' ocular symptoms improved with acyclovir, azithromycin, gemifloxacin, and tecovirimat after 3 weeks of treatment. The incidence of MPX has been on the rise in 2022, and this case represents a unique presentation and an addition to the pool of data pertinent to diagnosis and treatment of MPX and its ocular manifestations. Due to the MPX reemergence, it is imperative for ophthalmologists to keep MPX on the differential for patients presenting with blepharoconjunctivitis.

BACKGROUND infection is a major casual factor in any peptic diseases. Clarithromycin as one of the drugs recommended for the infection eradication regimen has shown different levels of resistance. The present study is comparing the effectiveness of clarithromycin- and gemifloxacin - based quadruple regimens in eradication. METHODS This was a prospective double blind randomized clinical trial on patients with clear indication of eradication. The patients were randomly divided into two groups: "BPAC group" treated with bismuth subcitrate (240 mg), pantoprazole (20 mg), amoxicillin (1 gr), and clarithromycin (500 mg), all twice daily, and the "BPAG group" treated with bismuth subcitrate, pantoprazole, and amoxicillin with same doses as "BPAC group" and gemifloxacin (320 mg daily) all for 10 days. Three months after the end of therapy, 14C-Urea breath test was performed to confirm the eradication. All the patients were assessed for compliance and drug side effects. Based on per-protocol (PP) and intention-to-treat (ITT) methods, data were analyzed and a P value<0.05 was considered as statistically significant. This project has been registered in the Iranian registry of clinical trials (IRCT). RESULTS Three patients were excluded from the survey and finally, 179 patients (89 patients in BPAC group and 90 patients in BPAG group) including 71(39.66%) men with the mean age of 46.4±12.3 years completed the treatment period. The incidence of side effects between the two study groups did not differ significantly. The success rate of BPAC regimen eradication was remarkably greater than BPAG regimen (ITT analysis; 89% vs 77%, respectively; CI 95%: 1.072-5.507, <0.015 and PP analysis; 91% vs 77.8% respectively; CI 95%: <0.015). There was no significant relationship between the demographic features and the eradication results. CONCLUSION The results showed that gemifloxacin is not a good alternative for clarithromycin in eradication regimens in our region.

•In eradication treatment of H. pylori gemifloxacin containing triple treatment regimen was as effective as bismuth containing quadruple treatment. •Drug adverse effects were fewer and milder in the gemifloxacin group. •Since treatment period was shorter and pills to be taken were fewer compared to quadruple treatment, patient compliance was significantly higher in the gemifloxacin group. Background - After eradication of Helicobacter pylori (H. pylori) chronic gastritis will resolve, complications due to H. pylori infection and recurrence of infection will be prevented. Objective - To determine efficacy and safety of gemifloxacin containing treatment regimen in first line treatment of H. pylori with comparison to bismuth containing quadruple therapy. Methods - This retrospective study was conducted in a tertiary care university hospital between January 2018 and January 2021 with 410 participants who were diagnosed to have H. pylori infection with biopsies obtained during upper gastrointestinal system endoscopy. Patients were distributed into two groups according to their first-line treatment regimens. First group patients were treated with amoxicillin, gemifloxacin and pantoprazole and second group patients were treated with amoxicillin, metronidazole, bismuth subcitrate and pantoprazole for seven days. Results - Intention to treat and per protocol ratios for gemifloxacin containing regimen were 90.0% and 91.2%, while quadruple treatment has these ratios as 91.7% and 93.8% respectively. Treatment success rate in both regimens were similar. But adverse effects were lower and patient compliance were better in patients who had gemifloxacin containing treatment (P<0.001). Conclusion - Gemifloxacin containing treatment regimen is as effective as bismuth containing quadruple treatment regimen for H. pylori infection and patient compliance is better in this group. Gemifloxacin containing treatment regimens may be novel and effective alternatives for eradication of H. pylori infection.

Fluoroquinolones (FQs) have been reported to cause dysglycemia in both diabetic and non-diabetic patients. However, diabetic patients are usually on polypharmacy, so we cannot attribute the dysglycemia specifically to FQs. To answer the question as to whether and influence blood glucose levels and serum insulin levels or otherwise, rabbits were used as experimental animals in an in vivo model followed by a phase I randomized clinical trial in euglycemic healthy volunteers. The effects on the serum insulin and blood glucose levels in the and treated groups were, respectively, determined on the fifth day in both the in-vivo rabbits model and in the test subjects of the phase I clinical trial. The effects of these drugs were also checked on the histomorphology of the pancreas in the rabbits. The findings of our study suggest that and significantly ( < 0.05) reduced the blood glucose levels via a subsequent significant shift in the serum insulin levels both in the in vivo animal model and in the test subjects of the phase I clinical trial. No prominent effects on the beta cells histomorphology were noted in this study. showed a more significant effect than . The insulinotropic effect was comparable to the effect of . It is concluded that and have a significant blood glucose lowering effect mediated through insulinotropic action. (Clinical Trials.gov identifier: NCT04692623).

BMJ (Clinical Research Ed.) Oct 2022To evaluate the association between initiation of fluoroquinolones and hospital admission or emergency department visit for suicidality.
OBJECTIVE
To evaluate the association between initiation of fluoroquinolones and hospital admission or emergency department visit for suicidality.
DESIGN
Population based cohort study.
SETTING
IBM MarketScan database, USA.
PARTICIPANTS
2 756 268 adults (≥18 years) who initiated an oral fluoroquinolone (ciprofloxacin, levofloxacin, moxifloxacin, gemifloxacin, ofloxacin, gatifloxacin, norfloxacin, lomefloxacin, besifloxacin) or comparator antibiotic (January 2003 to September 2015) and had at least six months of continuous health plan enrollment and a diagnosis of pneumonia or urinary tract infection (UTI) three days or less before the drug initiation date. Comparator antibiotics were azithromycin in the pneumonia cohort and trimethoprim-sulfamethoxazole in the UTI cohort. Participants were matched 1:1 within each cohort on a propensity score, calculated from a multivariable logistic regression model that included 57 baseline covariates.
MAIN OUTCOMES MEASURE
Primary outcome was hospital admission or emergency department visit for suicidal ideation or self-harm within 60 days after treatment initiation. Cox proportional hazard models were used to estimate hazard ratios and 95% confidence intervals.
RESULTS
The pneumonia cohort included 551 042 individuals, and the UTI cohort included 2 205 526 individuals. During the 60 day follow-up, 181 events were observed in the pneumonia cohort and 966 in the UTI cohort. The adjusted hazard ratios for fluoroquinolones were 1.01 (95% confidence interval 0.76 to 1.36) versus azithromycin in the pneumonia cohort and 1.03 (0.91 to 1.17) versus trimethoprim-sulfamethoxazole in the UTI cohort. Results were consistent across sensitivity analyses and subgroups of sex, age, or history of mental illnesses.
CONCLUSION
Initiation of fluoroquinolones was not associated with a substantially increased risk of admission to hospital or emergency department visits for suicidality compared with azithromycin or trimethoprim-sulfamethoxazole.

Review
BACKGROUND
Community-acquired pneumonia (CAP) is a lung infection that can be acquired during day-to-day activities in the community (not while receiving care in a hospital). Community-acquired pneumonia poses a significant public health burden in terms of mortality, morbidity, and costs. Shorter antibiotic courses for CAP may limit treatment costs and adverse effects, but the optimal duration of antibiotic treatment is uncertain.
OBJECTIVES
To evaluate the efficacy and safety of short-course versus longer-course treatment with the same antibiotic at the same daily dosage for CAP in non-hospitalised adolescents and adults (outpatients). We planned to investigate non-inferiority of short-course versus longer-term course treatment for efficacy outcomes, and superiority of short-course treatment for safety outcomes.
SEARCH METHODS
We searched CENTRAL, which contains the Cochrane Acute Respiratory Infections Group Specialised Register, MEDLINE, Embase, five other databases, and three trials registers on 28 September 2017 together with conference proceedings, reference checking, and contact with experts and pharmaceutical companies.
SELECTION CRITERIA
Randomised controlled trials (RCTs) comparing short- and long-courses of the same antibiotic for CAP in adolescent and adult outpatients.
DATA COLLECTION AND ANALYSIS
We planned to use standard Cochrane methods.
MAIN RESULTS
Our searches identified 5260 records. We did not identify any RCTs that compared short- and longer-courses of the same antibiotic for the treatment of adolescents and adult outpatients with CAP.We excluded two RCTs that compared short courses (five compared to seven days) of the same antibiotic at the same daily dose because they evaluated antibiotics (gemifloxacin and telithromycin) not commonly used in practice for the treatment of CAP. In particular, gemifloxacin is no longer approved for the treatment of mild-to-moderate CAP due to its questionable risk-benefit balance, and reported adverse effects. Moreover, the safety profile of telithromycin is also cause for concern.We found one ongoing study that we will assess for inclusion in future updates of the review.
AUTHORS' CONCLUSIONS
We found no eligible RCTs that studied a short-course of antibiotic compared to a longer-course (with the same antibiotic at the same daily dosage) for CAP in adolescent and adult outpatients. The effects of antibiotic therapy duration for CAP in adolescent and adult outpatients remains unclear.
