Ibalizumab: A Review in Multidrug-Resistant HIV-1 Infection

AbstractIbalizumab (Trogarzo®; ibalizumab-uiyk) is the first monoclonal antibody to be approved for the treatment of HIV-1 infection. As a CD4-directed post-attachment inhibitor, ibalizumab blocks HIV-1 entry into CD4 cells while preserving normal immune function. Ibalizumab, in combination with other antiretroviral(s), is indicated in the USA for the treatment of heavily treatment-experienced adults with multidrug-resistant HIV-1 infection failing their current antiretroviral regimen, and in the EU for the treatment of adults infected with multidrug-resistant HIV-1 infection for whom it is otherwise not possible to construct a suppressive antiviral regimen. In the pivotal phase III TMB-301 trial, ibalizumab significantly reduced the viral load 7  days after being added to a failing antiretroviral regimen. Almost half of all patients achieved an undetectable viral load after 24 weeks of treatment with ibalizumab plus an optimized background regimen, with virological suppression maintained over the longer term (up to 96 weeks) in an expand ed access protocol. The drug was generally well tolerated in clinical trials. Although additional studies and long-term post-marketing data are needed to fully determine its efficacy and safety, ibalizumab represents a valuable and much needed treatment option for patients with multidrug-resistant H IV-1 infection.

Authors: Gil-Gil T, Martínez JL, Blanco P Abstract Introduction: Stenotrophomonas maltophilia is a prototype of bacteria intrinsically resistant to antibiotics. The reduced susceptibility of this microorganism to antimicrobials mainly relies on the presence in its chromosome of genes encoding efflux pumps and antibiotic inactivating enzymes. Consequently, the therapeutic options for treating S. maltophilia infections are limited.Areas covered: Known mechanisms of intrinsic, acquired and phenotypic resistance to antibiotics of S. maltophilia and the consequences of such resistance for treating S. maltophilia ...

Conclusions: The MDR1/ABCB1 gene polymorphism rs 1045642 may be involved in the pathogenesis of CRC and this relationship may be sex-specific for males. However, further population studies are necessary to assess this relationship. PMID: 32051713 [PubMed]

Multidrug resistant (MDR) Salmonella strains are highly adaptive and have been responsible for several foodborne disease outbreaks. We investigated the genetic relatedness, antibiotic resistance and virulence genes of 160 strains which were recovered from 920 samples. The samples...

Authors: Akyüz S, Parlak M, Güdücüoğlu H Abstract Acinetobacter species lead to nosocomial infections in immunocompromised patients hospitalized in intensive care units or services. Acinetobacter baumannii is a bacterium that is difficult to treat because it is intrinsically resistant to many antibiotics and can develop resistance afterwards. This situation limits the use of existing antibiotics and directs the clinician to new agents, different treatment options and the use of various antibiotic combinations. The aim of this study was to determine the sensitivities of doripenem (DOR), tigecycl...

Pathogenic bacteria often carry large plasmids that contain multiple resistance genes; individually, these elements coselect for additional resistance genes that are genetically linked by the plasmid. In this short communication, we demonstrate increased triclosan resistance can be conjugatively transferred inStaphylococcus aureus. Furthermore, in a competition assay, we show subinhibitory concentrations of antiseptics abrogate the fitness cost of a large multidrug resistance plasmid inS. aureus, thus coselecting for the numerous antimicrobial resistance genes present on the plasmid. AbstractStaphylococcus aureus carries a...
