Sensitivity & Specificity of Xpert MTB/RIF Ultra

Status Not yet recruiting

Clinical Trial Summary

To estimate diagnostic accuracy of Xpert Ultra and Xpert MTB/RIF for extrapulmonary tuberculosis and rifampicin resistance in adults suspected to be infected with mycobacterium tuberculosis. In addition, this study will estimate the pattern of rifampicin resistance among TB cases in Assiut population.

Clinical Trial Description

Xpert MTB/RIF was introduced recently and added great benefit in management of TB. Xpert MTB/RIF revolutionized the management of Mycobacterium tuberculosis (MTB) infections by providing faster and more accurate MTB diagnosis that detects MTB and rifampicin (RIF) resistance simultaneously. Following World Health Organization (WHO) endorsement in 2010, Xpert MTB/RIF has helped improve TB programs in over 130 countries5. Building on this success, faster and more accurate detection of MTB from the first point of encounter in the community is critical. Partnered with GeneXpert® Systems, Xpert MTB/RIF Ultra was delivered with the advantages of improved performance and faster time to result (results within 80 minutes). It has higher sensitivity especially in smear-negative TB cases. The processing of the new assay is easy to use and does not need special expertise5. Xpert MTB/RIF Ultra has increased accuracy of Rifampicin results and improved detection of mixed infections. Recently published recommendations by global experts demonstrate the efficiency of using Xpert MTB/RIF Ultra as a frontline test over smear microscopy or line probe assays followed by culture-based methods for drug susceptibility testing. Thus, a single modification of the diagnostic algorithm to detect smear-positive and smear-negative TB patients improves active case management, is more cost-efficient and could potentially reduce the relative rate of transmission. Using Xpert MTB/RIF Ultra has the potential to reduce the number of missed smear-negative TB patients and may lead to a decrease in total costs of patient care due to the detection of MTB in patient specimens and RIF-resistance in a single test. There is great need for further research to assess the diagnostic value of Xpert MTB/RIF Ultra in patients with pulmonary tuberculosis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
