RESUMO
Objective:To explore the characteristics of T lymphocyte subsets and cytokines in hyperlipidemia-induced acute pancreatitis (HLAP) and its prognostic value.Methods:This study included 184 patients with acute pancreatitis (AP) admitted to the First Affiliated Hospital of Xiamen University from January 2018 to May 2021. Based on disease etiology, there were 92 HLAP cases and 92 non-hyperlipidemia-induced AP (NHLAP) cases. Stratified by disease severity according to 2012 Atlanta classification criteria, the patients were divided into the severe subgroup (SAP) and non-severe subgroup (NSAP). Peripheral venous blood samples were taken from all patients on day 1, 3, and 5 after admission. T lymphocyte subsets were determined by flow cytometry, and cytokines were detected by flow fluorometry. The number of CD4 +% and CD8 +% and the expression of cytokines were compared by Student’s t test or Mann-Whitney U analysis. Logistic regression analyses were performed to identify risk factors for severe AP, and a receiver operating characteristic (ROC) curve was constructed to predict severe AP. Statistical significance was taken as P<0.05. Results:Compared with the NHLAP group, patients in the HLAP group had lower CD4 +%, while higher levels of IL-2 on day 1 ( P<0.05), and had also lower CD4 +%, while higher levels of IL-4, IL-6, and IL-10 on day 3 ( P<0.05). Furthermore, IL-6 and IL-10 levels of the HLAP group were significantly increased compared to the NHLAP group on day 5 ( P<0.05). IL-10 levels in the SAP subgroup were significantly higher than those in the NSAP subgroup on day 1 ( P<0.05). Compared with the NSAP subgroup, the SAP subgroup had elevated levels of IL-2, IL-4, IL-6, IL-10 and IFN-γ on day 3 (all P<0.05), and had lower CD4 +%, while increased levels of IL-6 and IL-10 on day 5 (all P<0.05). Multivariate Logistic regression analysis showed that IL-10 was an immune indicator of independent risk factor for severe AP in the HLAP group on day 1 ( OR=1.139, 95% CI: 1.038-1.251, P<0.05). Finally, ROC analysis showed that the area under the curve of IL-10 to assess HLAP with severe AP was 0.772, and the best cut-off value for predicting severe AP was 5.6 pg/mL, with a sensitivity of 83.3% and a specificity of 68.8%. Conclusions:Changes of CD4 +% and cytokines are different between the HLAP and NHLAP groups. IL-10 can be used as a predictor of early disease severity in patients with HLAP.
RESUMO
A total of 192 patients with sepsis were tested by Montreal Cognitive Assessment (MoCA) for a preliminary diagnosis of whether or not there was sepsis associated encephalopathy (SAE) according to their test results.SAE was diagnosed or excluded after consultations and comprehensive analysis on the basis of clinical manifestations and auxiliary examination results.The scores of the patients in this group were (25.7 ± 3.3) points.The sensitivity of MoCA for screening SAE was 0.776 and its specificity 0.963.The rate of diagnostic coincidence between MoCA and comprehensive analysis for SAE was 0.880.The diagnostic concordance between two diagnostic methods of SAE was excellent (kappa value =0.753 ± 0.048,P =0.000).The area under the receiver operating characteristic (ROC) curve of MoCA for screening SAE was 0.929 ± 0.019 (P =0.000) ; the optimal cutoff value was 25.5 points; and its sensitivity was 0.779 and specificity 0.962.And negative correlations existed between score of MoCA and age,disease course and co-existing shock or multiple organ dysfunction syndrome (P ＜ 0.05).
