New Drugs for the Treatment of Tuberculosis

Tuberculosis (TB) has now surpassed HIV as the leading infectious cause of death, and treatment success rates are declining. Multidrug-resistant TB, extensively drug-resistant TB, and even totally drug-resistant TB threaten to further destabilize disease control efforts. The second wave in TB drug development, which includes the diarylquinoline, bedaquiline, and the nitroimidazoles delamanid and pretomanid, may offer options for simpler, shorter, and potentially all-oral regimens to treat drug-resistant TB. The “third wave” of TB drug development includes numerous promising compounds, including less toxic versions of older drug classes and candidates with novel mechanisms of action.

Conclusions: AEs were common, but not more frequent or severe among MDR-TB/HIV co-infected participants receiving concurrent antiretroviral therapy. Given the favorable treatment outcomes associated with concurrent treatment, antiretroviral therapy initiation should not be delayed in MDR-TB patients with HIV-coinfection.

ido A Abstract Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis and represents one of the leading causes of mortality worldwide due to multidrug-resistant TB (MDR-TB). In our work, a new formulation of biodegradable PLGA microparticles was developed for pulmonary administration of gatifloxacin, using a surface modifier agent to actively target alveolar macrophages thereby allowing to gain access of the drug to Mycobacterium tuberculosis. For this, rapid uptake of the particles by macrophages is beneficial. This process was evaluated with fluorescein-loaded microparticles using PLGA 5...

ConclusionsOur study provides the first insight into molecular epidemiology of MDR-TB in Kuwait and identified several potential clusters of local transmission of MDR-TB involving 2 –6 subjects which had escaped detection by routine surveillance studies. Prospective detection of resistance-conferring mutations can identify possible cases of local transmission of MDR-TB in low MDR-TB settings.

Despite all our efforts, the disease burden of tuberculosis (TB) is not falling fast enough to reach the 2030 milestone of the End TB strategy [1]. Multidrug-resistant tuberculosis (MDR-TB) remains a public health crisis, with low treatment success rates [1]. The repurposed drug linezolid has emerged as a core drug in MDR-TB treatment regimens [2, 3], despite its toxicity, e.g. anaemia, peripheral neuropathy and gastrointestinal disorders, optic neuritis, and thrombocytopenia [4, 5]. Currently, linezolid is used off-label, as part of Group A "Medicines to be prioritised" of the World Health Organization (WHO) MDR...

CYCLOSERINE ENANTIOMERS ARE REVERSIBLE INHIBITORS OF HUMAN ALANINE:GLYOXYLATE AMINOTRANSFERASE: IMPLICATIONS FOR PRIMARY HYPEROXALURIA TYPE 1. Biochem J. 2019 Dec 03;: Authors: Dindo M, Grottelli S, Annunziato G, Giardina G, Pieroni M, Pampalone G, Faccini A, Cutruzzolà F, Laurino P, Costantino G, Cellini B Abstract Peroxisomal alanine:glyoxylate aminotransferase (AGT) is responsible for glyoxylate detoxification in human liver and utilizes pyridoxal 5'-phosphate (PLP) as coenzyme. The deficit of AGT leads to Primary Hyperoxaluria Type I (PH1), a rare disease characterized by calcium oxalate st...

Rationale: The patient in this case report has been diagnosed with multidrug resistant lymph node fistula tracheobronchial tuberculosis (TBTB). The PubMed was searched using the keywords “Tuberculosis, Multidrug-Resistant”, “Tuberculosis”, and “Bronchial Fistula”, and the results yielded no similar case reports. Therefore, this report helps us to explore more on the causes of multidrug resistance and formation of lymph node fistula, as well as associated treatment strategies. Patient concerns: A 15-year old Tibetan girl who was previously treated in the local Hospital for Infectious...

Sandra Gemma Tuberculosis (TB) is one of the top 10 causes of death worldwide. This scenario is further complicated by the insurgence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB. The identification of appropriate drugs with multi-target affinity profiles is considered to be a widely accepted strategy to overcome the rapid development of resistance. The aim of this study was to discover Food and Drug Administration (FDA)-approved drugs possessing antimycobacterial activity, potentially coupled to an effective multi-target profile. An integrated screening platform was implemented based on comput...
