Identifying tuberculosis patients in Africa using passive methods is leaving many cases undiagnosed, according to researchers from the Netherlands, Kenya and the United States, who studied case detection methods in HIV-prone western Kenya. Tuberculosis (TB) occurs commonly in men and women with HIV, but in these patients TB can be more difficult to detect. The findings were published online ahead of the print edition of the American Thoracic Society's American Journal of Respiratory and...

Rethinking TB screening: Politics, practicalities and the press The current UK screening scheme for TB, which targets newly arrived immigrants from countries where tuberculosis is endemic, doesn't work and should be scrapped, say leading specialist doctors in this month's Thorax. The Port of Arrival Scheme, which has operated since 1971, focuses on those wishing to stay in the UK for at least six months and arriving from countries with high rates of TB - more than 40 per 100,000 of the...

VALENCIA, Calif., June 24 /PRNewswire/ -- Today the United States (U.S.) Centers for Disease Control and Prevention (CDC) issued new and important guidelines on the detection of Mycobacterium tuberculosis infections, the causative agent of tuberculosis (TB). In these landmark guidelines, CDC advises that Interferon Gamma Release Assay (IGRA) blood tests are now preferred over the 100+-year-old tuberculin skin test (TST) for diagnosing TB infection in certain populations, including people...

New finding may change the direction of vaccine research Scientists at NYU Langone Medical Center have discovered that the strategy of "immune evasion" common to many viruses, bacteria and parasites, is uncommon to M. tuberculosis where the antigens remain strikingly unchanged and homogenous. The study published in Nature Genetics on May 23, 2010, suggests that M. tuberculosis antigens do not mutate because they hope to be recognized by the body's immune system"“ perhaps because the...

HIV-infected patients who are falsely diagnosed as having tuberculosis (TB) have higher rates of mortality than those who are correctly diagnosed with the disease, according to a study conducted by researchers at University of California-San Francisco and Makerere University-Kampala. "Among HIV-infected persons with suspected TB, falsely diagnosing persons with TB by rapid testing was associated with increased mortality when compared with the group of patients who received the correct...

VALENCIA, Calif., April 6 /PRNewswire/ -- New data from a meta-analysis of existing literature published today in CHEST, the official journal of the American College of Chest Physicians, demonstrate that Interferon Gamma Release Assays (IGRAs) are superior to the previous standard in diagnostics, the 100+-year-old tuberculin skin test (TST), for detecting confirmed active Tuberculosis (TB) disease. This was especially true when the IGRAs, both QuantiFERON®-TB Gold (QFT),...

FORT LEE, N.J., Feb. 23 /PRNewswire/ -- A new breath test can detect active pulmonary tuberculosis, according to a report to be published in the journal "Tuberculosis." "The breath test was 85% accurate in detecting patients with active pulmonary tuberculosis," said Dr. Michael Phillips, developer of the breath test and CEO of Menssana Research, Inc based in Fort Lee, NJ. The National Institutes of Health funded the study of 226 patients in San Diego, London and the Philippines. Dr....

New optical technique provides easy way to detect TB bacteria in fluids Two billion people worldwide carry the pathogen that causes tuberculosis (TB), and most of them do not even know they are infected. This is because some 90 percent of people with TB have "latent" infections. They have no symptoms, they can't spread the disease to others and the bug remains dormant in their lungs -- often for years. Detecting latent TB infections is an important public health problem because those 10...

Active tuberculosis can be rapidly identified in patients with negative sputum tests by a new method, according to European researchers. Active tuberculosis (TB) is the seventh-leading cause of death worldwide, and while the diagnosis of active TB can be rapidly established when the bacteria can be identified on sputum microscopy, in about half of all cases, the TB bacterium cannot be detected, making another diagnostic option critical in efforts to control the spread of TB. The findings from...

U.S. researchers have determined that Mycobacterium tuberculosis has learned through evolution to coat itself with a sugar called mannose. This sugar makes the bacterium attractive to cells in the lungs that are looking to clean up and discard unwanted sugar in the body. Those lung cells absorb the TB bacteria, giving the infecting bacteria a place to live for the long term, Ohio State University researchers said. "The bug sugarcoats itself and creates this magical interaction that allows...
