In this study, we aimed to assess mRNA expressions of visfatin and lipocalin-2 in peripheral blood mononuclear cells (PBMCs) from patients with pulmonary tuberculosis (PTB).
Overall, 79 PTB patients and 71 healthy controls were enrolled. In PBMCs, mRNA expressions of visfatin and lipocalin-2 were detected using real-time quantitative polymerase chain reaction (qRT-PCR), and the diagnostic value of these adipokine mRNAs in PTB patients was calculated through receiver operating characteristic (ROC) analysis.
In PBMCs from PTB patients, the visfatin mRNA level was significantly higher than in healthy controls (P < .001), with no significant association between the lipocalin-2 mRNA level and PTB patients (P = .933). In PTB patients, lipocalin-2 mRNA expression positively correlated with the erythrocyte sedimentation rate (ESR) (P = .010). However, the visfatin mRNA level was not associated with any major clinical and laboratory parameter in PTB patients. The ROC curve demonstrated that visfatin could help distinguish PTB patients from healthy controls, with an optimal cutoff value of 0.645 and a corresponding sensitivity of 79.7%.
The altered visfatin mRNA expression indicated that this adipokine might play a role in PTB and could be an auxiliary biomarker for PTB diagnosis.
