Clinical Study of Recombinant Mycobacterium Tuberculosis ESAT6-CFP10 Allergen
Clinical Study of Recombinant Mycobacterium Tuberculosis ESAT6-CFP10 Allergen
720 cases TB (Tuberculosis patients) participants、360 cases non-TB participants with lung
 disease and suspected TB patients who all meet the standard are divided into different groups
 through a randomized and blind method. Every subject inject intradermally ESAT6-CFP10 and
 TB-PPD (tuberculin purified protein derivative) in different arms of the same person by blind
 method. Specific gama-interferon (γ-IFN) detection is needed before the injection.Measure the
 induration and (or) redness of longitudinal diameter size and transverse diameter vernier
 caliper by vernier caliper after injection 24h, 48h and 72h. At the same time, we observe all
 kind of adverse events.
Firstly, 720 cases TB (Tuberculosis) participants who meet the standard respectively are
 divided into different groups through a randomized and blind method.

 1. ESAT6-CFP10(10ug/ml) in left arm

 2. ESAT6-CFP10(10ug/ml) in right arm. Inject intradermally ESAT6-CFP10 and TB-PPD in
 different arms of the same participant. For each of participant, the person in this
 clinical research, the study uniform is that every subject injects firstly left arm,
 observe no obvious adverse reaction, then another drug inject in right arm. Measure the
 induration and (or) redness of longitudinal diameter size and transverse diameter
 vernier caliper by vernier caliper after injection 24h, 48h and 72h. At the same time,
 we observe the vital signs (breathing, heart rate, blood pressure and temperature),
 local reactions (rash, pain, itching and skin mucous membrane) and a variety of adverse
 events.

 Secondly, 360 cases non-TB participants with lung disease and suspected TB participants are
 divided into two different groups and the procedure are as the same as 720 cases TB.

 Thirdly,suspected TB participants are put under TB (Tuberculosis patients) or non-TB
 participants with lung disease by diagnosis when out group.

 Finally, we calculate the sensitivity (positive coincidence rate) by TB (Tuberculosis
 patients), the specificity (negative coincidence rate) by non-TB participants with lung
 disease, and verify the safety and effectiveness of ESAT6-CFP10(10ug/ml) for the clinical
 auxiliary diagnosis of tuberculosis.
