Combination of Lenvatinib and Antibiotics: A Potential Approach to Enhance Sensitivity in Differentiated Thyroid Cancer

International Journal of Cancer, EarlyView.
Although lenvatinib is the current first‐line therapy for radioiodine‐refractory differentiated thyroid carcinoma, its use is limited by severe side effects and reduced sensitivity. Here, the authors assessed the potential of sensitizing differentiated thyroid carcinoma tumor cells with limited lenvatinib responsiveness through the administration of ...

Potent monoclonal antibodies against multidrug‐resistant hypervirulent Klebsiella pneumoniae

Interdisciplinary Medicine, EarlyView.
A novel immunization strategy using a low‐virulence, multidrug‐resistant strain yields synergistic monoclonal antibodies against hypervirulent Klebsiella pneumoniae. These antibodies provide cross‐serotype protection through a dual‐mechanism of pathogen clearance and immunomodulation, offering a promising non‐antibiotic therapeutic for resistant ...

Evolutionary Trajectory of the Tet(X) Family: Critical Residue Changes towards High-Level Tigecycline Resistance

mSystems, 2021
The newly emerged tigecycline-inactivating enzymes Tet(X3) and Tet(X4), which are associated with high-level tigecycline resistance, demonstrated significantly higher activities in comparison to that of the prototypical Tet(X) enzyme, threatening the ...

Genomic Insights Into Carbapenem‐Resistant Klebsiella pneumoniae in Pediatric Bloodstream Infections in Zhejiang, China (2019–2024)

Journal of Clinical Laboratory Analysis, EarlyView.
The primary mechanism of carbapenem resistance identified in pediatric CRKP‐BSI strains was the production of Class B metalloenzymes. We report, for the first time, an outbreak of bloodstream infections in a neonatal ward caused by the dissemination of NDM‐1‐producing ST25 K. pneumoniae.

Acquisition of Tigecycline Resistance by Carbapenem-Resistant Klebsiella pneumoniae Confers Collateral Hypersensitivity to Aminoglycosides

Frontiers in Microbiology, 2021
Tigecycline is a last-resort antibiotic for infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP). This study aimed to broaden our understanding of the acquisition of collateral hypersensitivity by CRKP, as an evolutionary trade-off of ...

Tigecycline is efficacious in the treatment of complicated intra-abdominal infections [PDF]

, 2005
Background Empiric treatment of complicated intra-abdominal infections (cIAI) represents a clinical challenge because of the diverse bacteriology and the emergence of bacterial resistance. The efficacy and safety of tigecycline (TGC), a first-in-class,
