Physiologically-Based Pharmacokinetic model for Ciprofloxacin in children with complicated Urinary Tract Infection Vrije Universiteit Brussel
In a recent multicenter population pharmacokinetic study of ciprofloxacin administered to children suffering from complicated urinary tract infection (cUTI), the apparent volume of distribution (V) and total plasma clearance (CL) were decreased by 83.6% and 41.5% respectively, compared to healthy children. To understand these differences, a physiologically-based pharmacokinetic model (PBPK) for ciprofloxacin was developed for cUTI children. ...
Quantification of ciprofloxacin in pharmaceutical products from various brands using FT-NIR Vrije Universiteit Brussel
This study aims to quantify ciprofloxacin in commercial tablets with varying excipient compositions using Fourier Transform Near-Infrared Spectroscopy (FT-NIR) and chemometric models: Partial Least Squares (PLS) and Multivariate Curve Resolution - Alternating Least Squares (MCR-ALS). Matrix variation, arising from differences in excipient compositions among the tablets, can impact quantification accuracy. We discuss this phenomenon, ...
Intermediate susceptibility to ciprofloxacin among Salmonella enterica serovar Typhi isolates in Lima, Peru Instituut voor Tropische Geneeskunde
Thirty-three Salmonella enterica serovar Typhi blood isolates from Lima, Peru (2008 to 2012), were fully susceptible to trimethoprim-sulfamethoxazole, chloramphenicol, ceftriaxone, and tetracycline; 8/33 (24.2%) showed intermediate susceptibility to ciprofloxacin carrying mutations in the quinolone resistance-determining region of the gyrA gene (Ser83-Phe and Asp87-Asn) and in the gyrB gene (Ser464-Phe).
Pre-exposure to azithromycin enhances gonococcal resilience to subsequent ciprofloxacin exposure Instituut voor Tropische Geneeskunde
Background: The effect of sequential exposure to different antibiotics is an underexplored topic. Azithromycin can be detected in humans for up to 28 days post-ingestion and may prime bacterial responses to subsequently ingested antibiotics. Methods: In this in vitro study, we assessed if preexposure to azithromycin could accelerate the acquisition of resistance to ciprofloxacin in Neisseria gonorrhoeae reference strain, WHO-F. In a ...
