Patients were identified and followed using the healthcare databases of Emilia-Romagna Region, Italy. The outcome of interest was the first isolation from urine of an strain resistant to ciprofloxacin. Prescription of fluoroquinolones during the previous 6 months was associated independently with the emergence of ciprofloxacin resistance; the strength of the association varied according to individual fluoroquinolone agents. metoprolol metabolism 1Department of Epidemiology, Erasmus Medical Center, PO Box 2040, 3000 CA Rotterdam, The Netherlands2Inspectorate of Health Care, PO Box 2518, 6401 DA Heerlen, The Netherlands6Department of Internal Medicine, Erasmus Medical Center, PO Box 2040, 3000 CA Rotterdam, The Netherlands were collected from participants in the Rotterdam Study, a prospective cohort study in an elderly population, and analysed for susceptibility to ciprofloxacin. Multivariate logistic regression was performed to investigate several possible risk factors for resistance. Multivariate analysis showed that higher age (OR 1.03; 95% CI 1.00–1.05) and use of two (OR 5.89; 95% CI 3.45–10.03) and three or more (OR 3.38; 95% CI 1.92–5.97) prescriptions of fluoroquinolones were associated with ciprofloxacin resistance, while no association between fluoroquinolone use more than 1 year before culture and ciprofloxacin resistance could be demonstrated. Furthermore, a high intake of pork (OR 3.68; 95% CI 1.36–9.99) and chicken (OR 2.72; 95% CI 1.08–6.85) and concomitant prescription of calcium supplements (OR 2.51; 95% CI 1.20–5.22) and proton pump inhibitors (OR 2.04; 95% CI 1.18–3.51) were associated with ciprofloxacin resistance. Ciprofloxacin resistance in community-acquired UTI was associated with a high intake of pork and chicken and with concomitant prescription of calcium supplements and proton pump inhibitors. Modification of antibiotic use in animals as well as temporarily stopping the prescription of concomitant calcium and proton pump inhibitors need further evaluation as strategies to prevent ciprofloxacin resistance. With the increasing use of fluoroquinolones, selection of ciprofloxacin-resistant uropathogens has become widespread worldwide, ranging from 2% to 69% for uncomplicated and up to 98% for complicated UTIs. This also involves dose adjustment to obtain proper drug levels, since low levels of ciprofloxacin will influence the mutant selection window, resulting in faster selection of resistant subpopulations.

In the 1990s, the use of fluoroquinolones in the United States increased by ∼40%, with a doubling in the rate of resistance to ciprofloxacin. Resistant bacteria are spreading worldwide, which makes fast antibiotic susceptibility testing and determination of the minimal inhibitory. The increased use of fluoroquinolones has led to increasing resistance to these antimicrobials, with rates of resistance that vary by both organism and geographic region. Resistance to fluoroquinolones typically arises as a result of alterations in the target enzymes (DNA gyrase and topoisomerase IV) and of changes in drug entry and efflux. Mutations are selected first in the more susceptible target: DNA gyrase, in gram-negative bacteria, or topoisomerase IV, in gram-positive bacteria. Additional mutations in the next most susceptible target, as well as in genes controlling drug accumulation, augment resistance further, so that the most-resistant isolates have mutations in several genes. Resistance to quinolones can also be mediated by plasmids that produce the Qnr protein, which protects the quinolone targets from inhibition. Qnr plasmids have been found in the United States, Europe, and East Asia. Although Qnr by itself produces only low-level resistance, its presence facilitates the selection of higher-level resistance mutations, thus contributing to the alarming increase in resistance to quinolones.40 years ago. This study systematically reviewed the literature and where appropriate, meta-analysed studies investigating ciprofloxacin resistance in community- and hospital-acquired Observational studies published between 20 were identified through Medline, Pub Med, Embase, Cochrane, Scopus and Cinahl searches. Overall and sub-group pooled estimates of ciprofloxacin resistance were evaluated using Der Simonian-Laird random-effects models. The I Of the identified 1134 papers, 53 were eligible for inclusion, providing 54 studies for analysis with one paper presenting both community and hospital studies. Compared to the community setting, resistance to ciprofloxacin was significantly higher in the hospital setting (pooled resistance 0.38, 95 % CI 0.36-0.41 versus 0.27, 95 % CI 0.24-0.31 in community-acquired UTIs, UTI is increasing and the use of this antimicrobial agent as empirical therapy for UTI should be reconsidered. Policy restrictions on ciprofloxacin use should be enhanced especially in developing countries without current regulations. A recent World Health Organisation (WHO) report on antimicrobial resistance (AMR) surveillance specified nine bacteria of international concern which are responsible for some of the most common infections in community and hospital settings [, the pathogen most often implicated in UTIs, is listed as one of the nine. In all six WHO regions (Africa, Americas, Eastern Mediterranean, European, South-East Asia and Western Pacific) high rates of antimicrobial resistance have been observed in this pathogen  as they have an important role in the treatment of more severe infections, such as septicaemia. Therefore resistance to fluoroquinolones can have serious clinical consequences. Ciprofloxacin resistance Ciprofloxacin - Wikipedia, Mechanisms of Resistance to Quinolones Clinical Infectious.

Mutations in gyrA were absent. We recently demonstrated in Escherichia coli that the evolution of ciprofloxacin resistance both in vivo and in vitro requires the induction of stress response.
