Brief Summary
This is protocol is generated in response to the exploratory R21 from the National Institutes of Health/National Institute of Allergy and Infectious Diseases (NIH/NIAID) for US-Russia collaborative research in HIV/tuberculosis (TB). Given the exploratory focus of the protocol and the short time frame of funding (2 years) we will study TB in Irkutsk, in Eastern Siberia. Irkutsk is one of the hardest-hit areas in all of the Russian Federation for drug-resistant TB and poor TB outcomes. Specifically, the investigators will examine the factors of anti-TB drug pharmacokinetics, TB drug-resistance mutations and virulent/transmissible M. tuberculosis sublineages. This foundational work will inform future diagnostic strategies and therapeutic regimens.

Outcome Measures
Primary Outcomes (1)
TB drug-susceptibility testing
For subjects suspected of TB, sputum samples or other leftover sputum/blood specimens will be screened by GeneXpert and if positive, cultured for TB and the cultured specimen subjected to drug-susceptibility testing by conventional qualitative resistance and minimum inhibitory concentration (MIC), sequencing for drug-resistance mutation and spoligotyping for sublineage identification. Primary analysis will include standard sensitivity/specificity of each drug-mutation compared to conventional qualitative resistance and then median/range MIC values among isolates with/without mutation for improved discrimination.
The participants will be followed for the duration of hospital stay, an expected average of 12 weeks.
Secondary Outcomes (4)
The proportion of patients below the expected Cmax range
The participants will be followed for the duration of hospital stay, an expected average of 12 weeks.
The proportion of patients below the expected AUC range
The participants will be followed for the duration of hospital stay, an expected average of 12 weeks.
Correlation of Cmax with the primary outcome
The participants will be followed for the duration of hospital stay, an expected average of 12 weeks.
Correlation of AUC with the primary outcome
The participants will be followed for the duration of hospital stay, an expected average of 12 weeks.
Eligibility Criteria
Subjects will be enrolled from patients attending either Irkutsk Dispensary or the affiliate referral clinic (Irkutsk AIDS Center).
You may qualify if:
- All patients suspected of TB at Irkutsk Dispensary/Irkutsk AIDS Center.
- age \>15 years
You may not qualify if:
- Pregnancy (self reported)
- Prisoner or ward of the state

Biospecimen
We will collect and use plasma and sputum specimens. For a minority of subjects, leftover/discarded specimen may be used. Specimens will be stored under appropriate refrigeration (-80) at the Irkutsk Oblast Tuberculosis Dispensary and at UVa, MR6 Building Room 1701A, IBC# 327-05. Further HPLC analysis of the plasma will be conducted by Charles Peloquin, Pharm.D., FCCP (University of Florida).
