[Quantitative detection of Mycobacterium tuberculosis DNA in peripheral blood from patients with pulmonary
Objective:
To evaluate the clinical value of the quantitative detection of Mycobacterium tuberculosis DNA by Amplisensor-PCR in peripheral blood from patients with pulmonary tuberculosis.
Methods:
The model of Mycobacterium tuberculosis DNA in blood was made by QIAamp and AcuPure methods, quantitative detection of Mycobacterium tuberculosis DNA by AmpliSensor-PCR technique and the results were compared with IS6110 single-tube nested PCR (SN-PCR).
Results:
The peripheral blood from 200 patients with pulmonary tuberculosis were detected respectively by using AmpliSensor-PCR and IS6110 SN-PCR methods. The positive rates of Mycobacterium tuberculosis DNA were 60.5% and 63.5% respectively, and that from 85 patients with non-pulmonary tubeculosis were 4.7%, 8.2%.
Conclusions:
AmpliSensor-PCR method showed higher sensitivity and specificity in detecting the Mycobacterium tubeculosis DNA from peripheral blood. The variation of the TB-DNA may be useful in evaluating the prognosis of the patients.
