Th1/Th2 Imbalance and Elevated PD-L1 in Pleural Effusion Predict the Risk of Multi-Drug Resistant Tuberculous Pleuritis.

CONCLUSION: Evaluation of immune status based on PD-L1 pleural concentration and Th2 to Th1 ratio might predict the risk of MDR-TB occurrence. PMID: 32224537 [PubMed - in process]

In this study, we analyzed the distribution of Mycobacterium species, compare the diagnostic methods, and susceptibilities to anti-tuberculosis drugs of TB isolates. The aim was to document the current status and to provide a frame of reference for future studies. In this study, 278 Mycobacterium species isolated from 7,480 patients between September 2015 and June 2019 were included. Löwenstein-Jensen medium (LJ) and MGIT 960 were used for the isolation of strains. Susceptibility to 1st-line anti-tuberculosis drugs was determined. Positivity rates in clinical samples were as follows: 1.4% for direct microscopic acid-f...

AbstractPretomanid, a nitroimidazoxazine antimycobacterial agent, presents a valuable option for the treatment of adults with pulmonary extensively drug-resistant (XDR) tuberculosis (TB) or treatment-intolerant or nonresponsive multidrug-resistant (MDR)-TB when used as part of an all-oral combination regimen with bedaquiline and linezolid. In the pivotal phase  III Nix-TB trial, a combination regimen of pretomanid, bedaquiline, and linezolid for 6 months had a high treatment success rate. Besides the demonstrated effectiveness, the pretomanid, bedaquiline, and linezolid combination has other benefits, including t...

The world strives for progress towards accelerating the decline rate of tuberculosis (TB) incidence from 2% to 10% per year to reach the 2035 milestone of the End TB Strategy (WHO 2014). However, the appearance and growing incidence of drug-resistant TB impedes this progress largely. WHO estimated that in 2018, there were 484000 new cases with resistance to rifampicin (the most effective first-line drug) and 78% of these cases were multidrug-resistant TB (MDR-TB) (WHO 2019). Early and accurate diagnosis is of utmost importance to mitigate burden brought by MDR-TB (WHO 2010).

NEW BRUNSWICK, NJ, May 27, 2020 — The Janssen Pharmaceutical Companies of Johnson &Johnson today announced that the U.S. Food and Drug Administration (FDA) has granted approval for a new pediatric formulation of SIRTURO® (bedaquiline). SIRTURO® is now indicated for use as part of combination therapy in the treatment of adult and pediatric patients (5 years and older and weighing at least 15 kg) with pulmonary multidrug-resistant tuberculosis (MDR‑TB). In the U.S., the medicine should be reserved for use when an effective treatment regimen cannot otherwise be provided. This indication received accelera...

ConclusionsDiscovery delay for an index patient played a primary role in MDR-TB transmission inside the school. To immediately detect TB, morning examinations in schools should be performed. TB trackers and case managers should work closely with public health workers and physicians in cases of TB outbreaks or transmissions involving students. Moreover, individuals who are in close contact with MDR-TB patients should undergo careful clinical follow-up for at least two  years. Implementing a joint examination strategy to ensure early detection, diagnosis, and treatment of MDR-TB transmission is recommended.

Authors: Rodrigues L, Cravo P, Viveiros M Abstract Introduction: In 2018, an estimated 377,000 people developed multidrug-resistant tuberculosis (MDR-TB), urging for new effective treatments. In the last years, it has been accepted that efflux pumps play an important role in the evolution of drug resistance. Strategies are required to mitigate the consequences of the activity of efflux pumps.Areas covered: Based upon the literature available in PubMed, up to February 2020, on the diversity of efflux pumps in Mycobacterium tuberculosis and their association with drug resistance, studies that identified efflux inhibi...

lliam A. Denny Zhenkun Ma The introductions of the bicyclic 4-nitroimidazole and the oxazolidinone classes of antimicrobial agents represented the most significant advancements in the infectious disease area during the past two decades. Pretomanid, a bicyclic 4-nitroimidazole, and linezolid, an oxazolidinone, are also part of a combination regimen approved recently by the US Food and Drug Administration for the treatment of pulmonary, extensively drug resistant (XDR), treatment-intolerant or nonresponsive multidrug-resistant (MDR) Mycobacterium tuberculosis (TB). To identify new antimicrobial agents with reduced prop...
