Table 2. Linkage of trehalose-6-mycolate, phosphatidylinositol and the D-series resolvin metabolite(s) in plasma of patients without or with MDR-TB.

Metabolite feature	Non-MDR-TB patientsa b	MDR-TB patientsc	Household contactsd
Trehalose-6-mycolate	13/14	1/3	1/17
Phosphatidylinositol (PI)	14/14	1/3	1/17
D-series resolvin	12/14	2/3	2/17

^a In all 13 non-MDR-TB patients with detectable trehalose-6-mycolate metabolite in plasma, the phosphatidylinositol metabolite was also detected.

^b In all 12 non-MDR-TB patients with the D-series resolvin(s) metabolite detected in plasma, the trehalose-6-mycolate and PI metabolites were concomitantly detected.

^c One of 3 patients with MDR-TB demonstrated the D-series resolvin(s), trehalose-6-mycolate and PI metabolites in plasma.

^d One of the 17 smear-negative household contacts demonstrated both trehalose-6-mycolate and the PI metabolites in plasma, but these metabolites were undetectable the other household contacts.

The D-series resolvin metabolite(s) was detected in plasma of 2 other household contacts.
