Thiostrepton: A Novel Therapeutic Drug Candidate for Mycobacterium abscessus Infection
Mycobacterium abscessus is a rapid-growing, multidrug-resistant, non-tuberculous mycobacterial species responsible for a variety of human infections, such as cutaneous and pulmonary infections. M. abscessus infections are very difficult to eradicate due to the natural and acquired multidrug resistance profiles of M. abscessus. Thus, there is an urgent need for the development of effective drugs or regimens against M. abscessus infections. Here, we report the activity of a US Food and Drug Administration approved drug, thiostrepton, against M. abscessus. We found that thiostrepton significantly inhibited the growth of M. abscessus wild-type strains, subspecies, clinical isolates, and drug-resistant mutants in vitro and in macrophages. In addition, treatment of macrophages with thiostrepton significantly decreased proinflammatory cytokine production in a dose-dependent manner, suggesting an inhibitory effect of thiostrepton on inflammation induced during M. abscessus infection. We further showed that thiostrepton exhibits antimicrobial effects in vivo using a zebrafish model of M. abscessus infection
Left Atrial Appendage Occlusion Device and Novel Oral Anticoagulants versus Warfarin for Stroke Prevention in Non-Valvular Atrial Fibrillation: A Systematic Review and Meta-Analysis of Randomized Control Trials
-Non-valvular atrial fibrillation (NVAF) is the most common arrhythmia. Patients with NVAF are at increased risk of stroke, therefore we evaluated the efficacy and safety of different approaches to prevent this major complication
