The ability of long non-coding RNA RP11-284N8.3 to predict the risk, the severity and 28-day mortality of adults with sepsis. Issue 12 (24th March 2023) - Cheng, Yanwei
Abstract : In a prior study, we identified a novel sepsis specific long noncoding RNAs (lncRNA) RP11-284N8.3, which may primarily participate in T cell activation and immune response during sepsis. However, the clinical significance of lncRNA RP11-284N8.3 in sepsis remains entirely unknown. This single-center prospective cohort study enrolled 147 adults with sepsis and 74 healthy controls (HCs) with matched age and sex between January 2021 and November 2022 at our hospital. Blood samples and clinical data were collected from HCs at enrollment and from adults with sepsis within 24 hours after admission. lncRNA RP11-284N8.3 expression was detected by RT-qPCR. The relative expression of lncRNA RP11-284N8.3 was significantly decreased in adults with sepsis compared to HCs ( P < .0001), in adults with septic shock compared to adults without shock ( P = .0012), and in 28-day deaths compared to 28-day survivors ( P = .0006). receiver operating characteristic curves of lncRNA RP11-284N8.3 in predicting sepsis severity and 28-day mortality showed an area under the curve of 0.6570 (95% confidence interval [CI]: 0.5701–0.7440) and an area under the curve of 0.6765 (95% CI: 0.5809–0.7721), respectively. Multivariate logistic regression analysis revealed that lncRNA RP11-284N8.3 was an independent risk factor for 28-day mortality in adults with sepsis (odds ratio: 0.1057, 95% CI: 0.0115–0.7746, P = .0328). Low expression of lncRNA RP11-284N8.3 is correlated with increased risk, severity and 28-day mortality in adults with sepsis, and it may function as a potential biomarker to facilitate the diagnosis and management of sepsis.
