The efficacy and safety of a novel once-daily extended-release ciprofloxacin (ciprofloxacin ER) 500-mg dose were compared with those of an immediate-release ciprofloxacin (ciprofloxacin IR) 250-mg twice-daily dose, each administered orally for 3 days in the treatment of acute uncomplicated urinary tract infection (uUTI) in women. Adult female outpatients (mean age, 39 years) with clinical signs...
OBJECTIVES Widespread use of fluoroquinolones has led to increased levels of resistance in clinical isolates of Escherichia coli. We investigated the evolution of ciprofloxacin susceptibility and molecular epidemiology of clinical E. coli isolates in haematology patients receiving ciprofloxacin prophylaxis on the population and individual patient level. METHODS From August 2006 through Decemb...
The mechanisms of persistence to ciprofloxacin in nine sets of Pseudomonas aeruginosa strains isolated during ciprofloxacin therapy of chronic lung infections in cystic fibrosis patients were studied. Low to moderate levels of ciprofloxacin resistance developed in each case. Each set of pretherapy ciprofloxacin-susceptible, during-therapy ciprofloxacin-resistant, and posttherapy ciprofloxacin-s...
Ciprofloxacin, the most widely used totally synthetic antibiotic, is subject to active efflux mediated by a MRP-like transporter in wild-type murine J774 macrophages. To identify the transporter among the seven potential Mrps, we used cells made resistant to ciprofloxacin obtained by long-term exposure to increasing drug concentrations (these cells show less ciprofloxacin accumulation and provi...
BACKGROUND/AIMS Ciprofloxacin is considered to be a safe and effective treatment for acute infectious colitis. However, this drug may cause drug-induced pancreatitis, albeit rarely. METHODS From March 2007 to February 2012, we studied 227 patients who were hospitalized for infectious colitis at St. Mary's Hospital. All of the patients received ciprofloxacin therapy for the treatment of infect...
Ciprofloxacin, a fluoroquinolone antibiotic, is widely used for the treatment of bacterial infection in humans due to its broad antibacterial spectrum. An excessive use or overdose of ciprofloxacin on the other hand can cause several adverse effects not only to humans but also to microorganisms. Unabsorbed ciprofloxacin in the body is mostly excreted through urine and finally goes to the enviro...
OBJECTIVE To determine the frequency of E. coli resistance to ciprofloxacin and common factors leading to it among patients presenting with urinary tract infection. STUDY DESIGN Descriptive cross-sectional study. PLACE AND DURATION OF STUDY Department of Medicine, Ayub Teaching Hospital, Abbottabad, from December 2011 to June 2012. METHODOLOGY A total of 166 patients, > 18 years of age of...
For 177 gram-negative isolates, the MICs for ciprofloxacin ranged from 0.02 microgram/ml (Escherichia coli) to 0.31 microgram/ml (Pseudomonas aeruginosa). In time-kill curves, ciprofloxacin at 8 X the MIC almost completely killed 10(6) CFU of P. aeruginosa by 24 h. Ciprofloxacin at 4 X the MIC allowed bacterial regrowth by 24 h, with development of partial resistance to ciprofloxacin.
Activities of clinafloxacin, ciprofloxacin, levofloxacin, sparfloxacin, trovafloxacin, piperacillin, piperacillin-tazobactam, trimethoprim-sulfamethoxazole, ceftazidime, and imipenem against 354 ciprofloxacin-susceptible and -intermediate-resistant organisms were tested by agar dilution. Clinafloxacin yielded the lowest quinolone MICs (< or = 0.5 microg/ml against ciprofloxacin-susceptible orga...
A transrectal prostate biopsy is the most common procedure used to establish the diagnosis of prostate cancer. Prior to biopsy, patients are commonly given ciprofloxacin for prophylaxis. However, a complication of the procedure is infection with ciprofloxacin-resistant organisms, in particular resistant Escherichia coli. In order to identify patients carrying ciprofloxacin-resistant E. coli, so...
