Seattle: An international team of researchers has identified biological markers in the blood that can help doctors predict who is at high risk of developing active tuberculosis (TB).

One-third of the world’s population is thought to be infected with Mycobacterium tuberculosis (Mtb), the bacterium that causes tuberculosis, but just a small fraction ever develops symptomatic illness.

If validated through additional clinical trials, a test based on these blood biomarkers that the researchers have now identified would allow doctors to target therapies to at-risk people, thus preventing them from getting sick.

The decade-long research effort was led by investigators from the South African Tuberculosis Vaccine Initiative at the University of Cape Town, and the Center for Infectious Disease Research, Seattle, US.

The findings were published in the journal The Lancet.

The biomarkers were identified in two stages. First, researchers collected blood samples for two years from more than 6,000 Mtb-infected but otherwise healthy adolescent volunteers in South Africa.

Analysis of the samples revealed patterns of gene expression that differed between volunteers who eventually developed TB and those who remained healthy.

This risk “signature,” confined to a set of 16 genes, could be detected in a blood sample as early as 18 months before the infected person developed active TB.

Next, the team confirmed the genetic risk signature’s predictive ability in a study of more than 4,500 volunteers in South Africa and The Gambia.

The second study group was more varied in age, health status, ethnicity and exposure to locally common strains of Mtb than volunteers in the first study.

Despite the differences, the same risk signature found in the first study was detected in the people who eventually developed active TB during the second trial. (IANS)

In a bid to promote the use of big data methods in biological applications, six Indian institutes of higher education on Wednesday established the first joint Indo-German research training group (RTG).

The six institutes — Indian Institutes of Technology at Guwahati, Kanpur and Madras, University of Allahabad, University of Delhi and Jawaharlal Nehru University — will partner with Germany’s Heidelberg University, and Department of Biotechnology (DBT) under the Ministry of Science and Technology.
