Better views of TB lungs may save lives and stop spread (post)
High-tech images of the lungs of people with “latent” tuberculosis (TB) identified those at risk of developing symptoms. The new work, which researchers presented in a special TB session at the 21st International AIDS Conference held in Durban, South Africa last week, suggests new ways to evaluate whether treatment has cured an infection. But it could also upend the conventional wisdom that billions of people are walking around with dormant TB in their lungs that could one day erupt in full-fledged disease.
Training community health workers leads to surge in TB diagnoses in Malawi (post)
An intervention using community health workers -- who normally provide case management support for HIV-positive pregnant women and their families -- to also provide intensified tuberculosis (TB) case finding was associated with a dramatic 20-fold increase in TB detection at a very busy antiretroviral therapy (ART) clinic in rural Malawi, according to a study presented at the 21st International AIDS Conference last week in Durban.
Why the world needs an Essential Diagnostics List (post)
Without diagnostics, medicine is blind. And yet, diagnostics receive much less attention than vaccines and drugs. Imagine a sick infant with bacterial sepsis in sub-Saharan Africa. Without diagnostics, they will likely get incorrectly treated for malaria. Every year, 1 million patients with TB in India are either not diagnosed or not reported. Pregnant women with anemia, syphilis and diabetes are often missed in low-income countries where laboratory capacity is severely lacking. And where there is testing, it is often of low quality.
Mozambique: Over eight thousand children show signs of TB (post)
Maputo — More than 300,000 children between the age of six months and five years old were screened for tuberculosis during Mozambique's National Health Week which ended on 29 July. According to figures released by the Ministry of Health, over eight thousand children presented signs of tuberculosis.
BC researchers collaborate with Oxford University and Public Health England to make TB genomic data quick and easy to read for clinicians (post)
VANCOUVER, BC, August 09, 2016 - A new project involving the BC Centre for Disease Control (BCCDC), Oxford University and Public Health England (PHE) is building data-sharing capacity between the three groups to accelerate the use of genomics as a tool for the diagnosis, treatment and tracking of tuberculosis (TB). Funded in part by Genome BC, this pioneering work will support PHE and BCCDC's efforts to validate the use of a genomic platform in a clinical setting through developing user-friendly reports to assist doctors in faster and more effective diagnosis and treatment.
New insight into the progression of TB infection (post)
Scientists have found evidence of a separate stage in tuberculosis (TB) infection, where people have no symptoms but are more likely to develop the full disease.
5% of Chennai TB patients’ kin found infected (post)
CHENNAI: Living with someone who is infected with tuberculosis can push up the risk of infection by more than two times, a study by National Institute for Research in Tuberculosis has found.
USPSTF: Screen at-risk adults for latent TB (post)
Asymptomatic adults at higher risk for latent tuberculosis infection (LTBI) should be screened in primary care settings, advises a new recommendation statement from the US Preventive Services Task Force (USPSTF).
Ugandan experience shows TB detection can be successfully incorporated into community HIV testing campaigns (post)
Community health campaigns provide an opportunity to detect previously undiagnosed cases of tuberculosis (TB), investigators report in the online edition of the Journal of Acquired Immune Deficiency Syndromes. Research conducted in rural Uganda showed that incorporating TB screening into community health campaigns offering universal HIV testing led to the diagnosis of undetected TB cases. Overall, approximately 3000 patients need to be screened to identify one new case of TB, but among patients with HIV and chronic cough, the yield was one new TB diagnosis per 80 screens.
