High-throughput autoantibody analysis in malignant pleural effusion and tuberculosis pleural effusion.

ABSTRACT: BACKGROUND:Malignant pleural effusion (MPE) and tuberculosis pleural effusion (TPE) are 2 kinds of common pleural diseases. Finding efficient and accurate biomarkers to distinguish the 2 is of benefit to basic and clinical research. In the present study, we carried out the first high-throughput autoantibody chip to screen the beneficial biomarker with samples of MPE and TPE and the corresponding serum. METHODS:We collected pleural effusion and serum of patients with MPE (n?=?10) and TPE (n?=?10) who had been in Beijing Chao-Yang hospital from June 2013 to August 2014. Using RayBio Human Protein Array-G2 to measure the concentration of 487 defined autoantibodies. RESULTS:Fold changes of Bcl-2-like protein 11 (BIM) autoantibody in MPE-serum/TPE-serum and MPE/TPE groups were 10 (P?=?.019) and 6 (P?=?.001); for decorin autoantibody, MPE-serum/TPE-serum ratio was 0.6 (P?=?.029), and MPE/TPE ratio was 0.3 (P?
