Abstract:
Objective:To explore the clinical application and diagnosis of the long non-coding RNA plasmacytoma variant translocation gene 1 (PVT1) in plasma for rheumatoid arthritis (RA).Methods:One hundred and nineteen healthy individuals were designed as healthy control (HC), 158 patients with RA, 50 patients with systemic lupus erythematosus (SLE) and 50 patients with primary Sj?gren′s syndrome (pSS) were collected from Xuzhou Central Hospital. The plasma PVT1 of HC, RA, SLE and pSS patients and were determined by real time polymerase chain reaction (qRT-PCR). The t test of two independent-samples and One-Way analysis of variance (ANOVA) were used to compare the levels of plasma PVT1 in HC, RA, SLE and pSS patients. The correlation between PVT1 and RF, IL-6 and anti-CCP of RA patients were analyzed by Spearman's rank correlation test. Receiver operating characteristic (ROC) curves were used to identify the diagnostic performance of plasma PVT1 for RA. Results:Compared to HC [(1.32±1.22)], SLE [(1.15±0.83)] and pSS patients [(1.46±0.88)], the plasma PVT1 relative expression [(3.71±2.68)] were significantly increased in RA patients ( t=8.36, P<0.01; t=6.83, P<0.01; t=5.98, P<0.01). The PVT1 had a strong positive correlation with RF, IL-6 and anti-CCP( r=0.41, P<0.01; r=0.38, P<0.01; r=0.40, P<0.01). The area under curve (AUC) of plasma of PVT1 of RA was 0.79[95% CI(0.72, 0.85); P<0.01]. At the optimal cut-off of 1.97, the diagnostic sensitivity and specificity were 68.27% and 86.45%, and in this point provided better diagnostic accuracy. When combination PVT1 with RF, the AUC was 0.88[95% CI(0.83, 0.93); P<0.01], the sensitivity and specificity were 80.22% and 82.73%. Conclusion:Plasma PVT1 has potential diagnostic value for RA, which may become a new biomarker for the diagnosis for RA patients.
