Between the LTBI and TB at diagnosis groups, IL-6 (2.7 vs. 64 pg/ml, p=0.018), MCP-1 (18.30 vs. 34.05, p=0.043), DcR3 (0.64 vs. 3.97 ng/ml, p<0.001), and PGE2 (0.31 vs. 3.04, p=0.001) were significantly higher in the latter, whereas lipoxin (3.391 vs. 1.73, p=0.008) was significantly higher in the former. This evidence concerns the gene IL6 and tuberculosis.
