Rapid diagnosis of tuberculosis is expected to break through the "bottleneck" source: xinhuanet.com
Xinhua Beijing, April 30 (reporter Hu Hao) rapid and accurate diagnosis is very important to inhibit the spread of tuberculosis and effective treatment of tuberculosis, reduce the prevalence, curb drug resistance and so on. Recent studies have shown that the lack of rapid and accurate diagnostic methods, the "bottleneck" of global TB control, is expected to be broken through.
According to a press release released by the World Health Organization on World Tuberculosis Day, the number of people suffering from tuberculosis worldwide is estimated to reach 9 million every year, one third of whom are unable to get the treatment they need. According to 2012 data, there are about 500000 MDR-TB patients in the world, and less than a quarter of them have been diagnosed.
At present, it usually takes 3 to 4 weeks to produce a test report for the commonly used clinical diagnosis methods of tuberculosis. The test cycle for patients is long, which often delays the clinical treatment, and the test price is expensive, so it is not suitable for general survey or large-scale promotion. If it can be diagnosed quickly, it can not only gain valuable time for patients to get targeted treatment, but also greatly reduce the chance of TB transmission.
In response, who said that progress has been made in the diagnosis of tuberculosis. Compared with traditional detection methods, which take a long time, the new technology can achieve rapid diagnosis of tuberculosis and MDR-TB within two hours. Currently, the technology is being promoted in 27 low - and middle-income countries to help them improve the diagnostic capacity of tuberculosis.
According to Philippe, executive vice president of Saipei's international business, a new type of rapid molecular biological test called xpert MTB / RIF can diagnose tuberculosis and drug-resistant tuberculosis in less than 2 hours. If this new type of detection can be popularized in China, especially in the grass-roots areas, it can not only detect TB patients early, but also adjust the treatment plan for drug-resistant TB in time, and promote the prevention and control of TB in China. At the same time, the rapid diagnosis technology of tuberculosis in China is also under research and development. Shanghai public health clinical center and Hangzhou CDC are carrying out clinical trials on the ATP bioluminescent TB isoniazid resistant test kit.
