- Brief Summary
In this clinical research,48 cases TB (Tuberculosis patients) participants and 48 cases non-TB participants with lung disease 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 in order to assess the safety of drug.
- Detailed Description
In this clinical research,we make sure of the safety in the crowd 5-18 years old firstly,then carry out the crowd of under 5 years old(including 5).
Firstly, 24 cases TB (Tuberculosis) participants and 24 cases non-TB participants with lung disease who are all 5-18 years old and meet the standard respectively are divided into different groups through a randomized and blind method.
1. ESAT6-CFP10(10ug/ml) in left arm and TB-PPD in right arm
2. ESAT6-CFP10(10ug/ml) in right arm and TB-PPD in left 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, 24 cases TB (Tuberculosis) participants and 24 cases non-TB participants with lung disease who are all less than 5 years old are divided into two different groups and the procedure are as the same as 5-18 years old.
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.

- Primary Outcome Measures
Name Time Method The diameter of induration or redness at the injection sites measured transversely to the long axis of the forearm 24 hours、48 hours and 72 hours after application of the agents From injections to 1-3 days after aplication After skin test 1-3d,subjects's injection site may appear inuration or redness .The diameters of induration or redness are measured and recorded.The number of diameter of induration or redness\<5mm，the result is negtive.If the number of diameter are not lower than 5mm,the result is positive.
- Secondary Outcome Measures
Name Time Method Number of participants with Adverse Events within 72h after injection two drug each participant Any AE of every subject appeared is recorded and traced after signing ICF,until remission of AE.
