New generation of drugs show early efficacy against drug-resistant TB
(Harvard Medical School) New drug regimen for multidrug-resistant tuberculosis shows early effectiveness in 85 percent of patients in a cohort including many with serious comorbidities. The results suggest a global need for expanded access to two recently developed medicines, bedaquiline and delamanid. Study cohort included many people who would have been excluded from trials because of comorbidities, severity of disease or extent of drug resistance. Findings highlight the importance of innovative regimens to improve outcomes for patients with multidrug-resistant tuberculosis.
This study is expected to report the performance of integrated TB/HIV treatment programs as regards their potential to uphold successful MDR-TB treatment outcomes in LMICs. Furthermore, the review will indicate patient-related and healthcare-related factors that should be addressed to improve on survival of patients with MDR-TB/HIV co-infection in LMICs.Systematic review registrationThis review has been registered with the International Prospective Register of Systematic Reviews and the reference ID is CRD42020159745
Conclusions: Delivery of granulysin by recombinant adenovirus to the infected lung could enhance the clearance of TB in vivo and might be a promising adjunct therapeutic vaccine for TB and MDR-TB.
Purpose of review Urinary tract infections (UTIs) belong to the most common community-acquired and nosocomial infections, but therapy of UTIs is limited by resistance of pathogens and nonoptimal using of antibacterials. Narrative review of recent (2020–2018) literature dedicated to antimicrobial stewardship (AMS) in urological infections has been done. Recent findings Analysis of recent 64 articles has shown following principles of AMS for UTIs: selecting the correct drug, correct dose, and shortest clinically effective duration of therapy whenever possible, is a base for optimal antimicrobial stewardship; sympt...
CONCLUSIONS: This study suggests an important role of oxidative stress as a major pathogenetic mechanism of riminophenazine-induced cardiac dysfunction. PMID: 33017766 [PubMed - as supplied by publisher]
Conclusions: This first documentation of Rifampicin resistance patterns in MTB from Nigeria shows that a majority ofrpoB gene mutations occurred along codons 523 to 527, contrary to the widely reported codon 531 mutation and that multiple interventions such as combination therapy, with good compliance to treatment are needed to reduce both prevalence and development of TB drug resistance in the population.
Multidrug-resistant Mycobacterium tuberculosis remains a major public health threat; its management poses a significant economic burden. Treatment requires a programmatic approach with access to laboratory services, second-line medications, and adequate clinical resources. In recent years, we have seen rapid developments in diagnostic techniques with whole genome sequencing –based drug susceptibility prediction now in reach, an array of new drugs that transform treatment regimens to purely oral formulations, and a steady stream of multinational trials that inform us about most efficient combinations. Our hope is that...

Conclusions: This study offers important details of the epidemiological profile of XDR-TB in Peru, where there has been an increase in cases of primary XDR-TB; that is, cases with no prior history of disease. Furthermore, this form of tuberculosis has spread to a greater number of departments in the country. PMID: 32973891 [PubMed]
Authors: Seddon JA, Johnson S, Palmer M, van der Zalm MM, Lopez-Varela E, Hughes J, Schaaf HS Abstract Introduction An estimated 30,000 children develop multidrug-resistant (MDR) tuberculosis (TB) each year, with only a small proportion diagnosed and treated. This field has historically been neglected due to a perception that children with MDR-TB are challenging to diagnose and treat. Diagnostic and therapeutic developments in adults have improved paediatric management, yet further paediatric-specific research and wider implementation of evidence-based practices are required. Areas covered This review combines the ...
