Serum proteins TGFBI, PCSK9, and CCL14 are potential biomarkers for different traditional Chinese medicine syndromes of multidrug‐resistant tuberculosis

Patients with multidrug‐resistant tuberculosis (MDR‐TB) tend to have a long course of anti‐TB treatment and severe side effects. Traditional Chinese Medicine (TCM) has a synergistic effect in attenuation of MDR‐TB. However, the lack of objective biological standards to classify and diagnose MDR‐TB T...

Description
Summary:Patients with multidrug‐resistant tuberculosis (MDR‐TB) tend to have a long course of anti‐TB treatment and severe side effects. Traditional Chinese Medicine (TCM) has a synergistic effect in attenuation of MDR‐TB. However, the lack of objective biological standards to classify and diagnose MDR‐TB TCM syndromes could result in less effective TCM treatment. Therefore, in this study, we identified differentially expressed proteins (DEPs) in serum of individuals with MDR‐TB TCM syndromes by applying isobaric tags for relative and absolute quantification coupled with two‐dimensional liquid chromatography–tandem mass spectrometry (iTRAQ‐2DLC–MS/MS) method and bioinformatics analysis. The functional analysis of DEPs was also performed. Additionally, DEPs among three different TCM syndromes of MDR‐TB were validated by enzyme‐linked immunosorbent assay (ELISA). Finally, a receiver operating characteristic (ROC) curve was performed to estimate the diagnostic ability of DEPs. A total of 71 DEPs were identified in the three different MDR‐TB TCM syndrome groups such as the pulmonary Yin deficiency (PYD) syndrome group, the Hyperactivity of Fire due to Yin deficiency (HFYD) syndrome group, and the deficiency of Qi and Yin (DQY) syndrome group. The results showed that the expression level of transforming growth factor‐beta‐induced protein ig‐h3 (TGFBI) was lower in the PYD syndrome group (p = .002), the proprotein convertase subtilisin/kexin type 9 (PCSK9) was overexpressed in the HFYD syndrome group (p
