Real world drug treatment models for pregnancy complicated with urinary tract infection in China from 2018 to 2022: a cross-section analysis
Conclusion: In the 5 years of research, the average age of patients who visit a doctor has not increased substantially, but the opportunity cost of female fertility has increased, which has severely impeded the fulfillment of fertility desires. The selection of medications is generally reasonable, and the dosage of the first-line cephalosporins recommended by the guidelines is relatively high in this study. The dosage of furantoin and fosfomycin, which are more prevalent in urinary tract infections, is however relatively low. In addition, some expensive pharmaceuticals may increase patients’ financial burden. On the pre...

Clofazimine-associated enteropathy
A 36-year-old man presented to the gastroenterology department because he had experienced intermittent abdominal pain for 1 year. He had received a diagnosis of multidrug-resistant pulmonary tuberculosis 2 years earlier and had received a drug regimen containing clofazimine, linezolid, protionamide, cycloserine, pyrazinamide, and moxifloxacin for 19 months. The abdominal pain occurred after he had been taking clofazimine for 7 months. Physical examination showed skin darkening. Laboratory results showed no abnormalities.

Hematological adverse events associated with anti-MRSA agents: a real-world analysis based on FAERS
This study investigated the patterns of hematological adverse events related to daptomycin (DAP), tigecycline (TIG), vancomycin (VAN) and linezolid (LIN) in the FDA Adverse Event Reporting System (FAERS). Adverse event associations were analyzed through calculating reporting odds ratio (ROR), proportional reporting ratio (PRR), multiple gamma Poisson shrinkage (MGPS), and Bayesian confidence propagation neural network (BCPNN). A comprehensive descriptive analysis was also conducted considering factors such as age, gender, daily dose, cumulative dose, and time to onset. The leading hematologic adverse events were eosinophil...

Genomic characterization of vancomycin-resistant Enterococcus faecium clonal complex 17 isolated from urine in tertiary hospitals in Northeastern Thailand
This study investigated VREfm isolates from rural tertiary hospitals in Northeastern Thailand based both antibiotic susceptibility testing and whole-genome sequencing. All isolates showed resistance to vancomycin, ampicillin, erythromycin, tetracycline, ciprofloxacin, norfloxacin, and rifampin. Nitrofurantoin and tigecycline resistance were also observed in nearly all isolates. Conversely, all isolates remained susceptible to chloramphenicol, daptomycin, and linezolid. Genomic characterization revealed that all VREfm isolates belonged to clonal complex 17 (CC17), primarily consisting of sequence type (ST) 80, followed by S...

Towards a better detection of patients at-risk of linezolid toxicity in clinical practice: a prospective study in three Belgian hospital centers
Conclusion: Our work supports the necessity of establishing guidelines for dose adjustment in patients with renal insufficiency and the systematic use of TDM in patients at-risk in order to keep trough values ≤8 mg/L. The Buzelé predictive score (if ≥7) may help to detect these at-risk patients, and pop-PK models can estimate trough levels based on plasma samples collected at varying times, reducing the logistical burden of TDM in clinical practice.

Preclinical toxicity evaluation of novel antibacterial contezolid acefosamil in rats and dogs
AbstractContezolid acefosamil (CZA) is an intravenous prodrug of oxazolidinone antibiotic contezolid (CZD). It is being developed to treat infections due to Gram-positive bacteria including multidrug-resistant pathogens, while addressing myelosuppression and neurotoxicity limitations associated with long-term use of this class of antibiotics. In vivo, CZA is rapidly deacylated into its first metabolite MRX-1352, which is then dephosphorylated to release active drug CZD. Four-week repeat-dose toxicity studies of intravenous CZA were conducted in Sprague –Dawley rats (40, 80, and 160/120 mg/kg/dose twice a day [BID]) and...

High Gastrointestinal Colonization Rate of Vancomycin-Resistant < em > Enterococci < /em > among Hospitalized Patients: Potential Source for Resistant Gene
CONCLUSIONS: In our study, high proportion of vancomycin-resistant Enterococci was found. Previous exposure to antibiotics and hospital stay were significant factors for VRE gut colonization. The isolated Enterococci showed variable degrees of resistance to commonly prescribed antibiotics which leads to a worldwide problem multidrug resistance. Therefore, periodic surveillance on antimicrobial resistance pattern, adhering to rational use of antibiotics, and implementing infection prevention protocols may reduce colonization by VRE.PMID:38226181 | PMC:PMC10789508 | DOI:10.1155/2024/6430026 (Source: International Journal of Microbiology)

Off-label oritavancin treatment outcome and molecular characterization of a vancomycin- and linezolid-resistant Enterococcus faecium causing liver abscesses
Among vancomycin-resistantEnterococcus faecium (VRE) strains, linezolid resistance (LR) is increasing. Long-acting oritavancin is active against Staphylococci and Enterococci, even for those displaying LR, and despite its approval for acute skin/soft tissue infections, off-label uses have been already described.1,2 (Source: Journal of Antimicrobial Chemotherapy)
