Over the past couple of weeks there have been much discussion and reporting on totally drug-resistant tuberculosis (TDR-TB) based on reports of new cases in India. Here are links to coverage of TDR-TB in India, excerpt from a response by Dr. Nardell who we interviewed last year, and link to the WHO Fact Sheet on TDR-TB. Additional links to TB R&D News are included.
The United Nations (UN) released a report on July 12 on the progress made thus far on the 8 Millennium Development Goals (MDGs). The eight MDGs include: end poverty and hunger, universal education, gender equality, child health, maternal health, combat HIV/AIDS, environmental sustainability, and global partnership. Key highlights and additional coverage on the report are included.
In the July 7 issue of the New England Journal, two articles and an editorial on latent TB and TB prevention are published. One study discusses positive results on a treatment for latent TB in HIV-infected persons. The other study discusses negative findings that isoniazid is not effective in latent treatment of tuberculosis in children regardless of HIV status. A link to MedPage Today is included that provides a good overview of these studies and the editorial. Additional TB R&D News Links also are included.
This week we look again at the role of efflux pumps in resistance to anti-tuberculosis drugs. Louw, et al., sought to “demonstrate that the level of rifampicin resistance is defined by efflux, which regulates the intracellular concentration of rifampicin.” This is a shift from the current thinking in the field that rifampicin resistance is solely the result of mutations in the rpoB gene. The article entitled “Rifampicin Reduces Susceptibility to Ofloxacin in Rifampicin Resistant Mycobacterium tuberculosis through Efflux” was published ahead of print in the American Journal of Respiratory and Critical Care Medicine. Additional links to TB R&D News is included.
On June 6, 2011, the Stop TB Partnership launched the initiative Time to Act–Save a Million Lives by 2015 at the UN Headquarters at a reception hosted by Ray Chambers, the UN Secretary-General’s Special Envoy for Malaria and UN MDG Advocate.
