The aim of this study was to investigate the predictive value of the platelet-to-lymphocyte ratio (PLR) and the China Acute Myocardial Infarction registry-ST segment elevation myocardial infarction (CAMI-STEMI) score for major adverse cardiovascular events (MACE) in ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI) within 6 months.We enrolled STEMI patients who received emergency PCI in the First Hospital of Lianyungang from January 2016 to December 2019. The clinical characteristics of the patients, the PLR, and the CAMI-STEMI score were recorded. The MACE included heart failure, nonfatal re-infarction, recurrent angina pain, re-hospitalization for cardiovascular-related illness, repeat PCI, coronary artery bypass grafting, and all-cause mortality. According to the incidence of MACE during the follow-up the patients were divided into the MACE group (96 cases, 24.8%) and the non-MACE group (291 cases, 75.2%).The PLR, 147.62 (121.13–205.20) in MACE group, was 111.19 (90.23–146.42) in the non-MACE group in comparison, the PLR was higher in MACE group than that in non-MACE group (P < .01). Multivariate regression analysis showed that PLR (odds ratio (OR) = 1.007, 95% confidence interval (CI) 1.002–1.012, P < .01) and CAMI-STEMI score (OR = 1.575, 95% CI: 1.311–1.892, P < .01) were independent predictors of MACE. Besides, I-BIL was also an independent predictor of MACE (OR = 1.007, 95% CI: 1.011–1.146, P = .021). Reciever-operating characteristic curve showed that the area under curve of PLR was 0.704 (95%CI 0.644–0.763, P < .001). The cutoff value was 112.6, the sensitivity and specificity were 84.4% and 51.9%, respectively.PLR and CAMI-STEMI scores were independent risk factors of MACE after PCI in STEMI patients.

Prognostic significance of neutrophil to lymphocyte ratio in pancreatic cancer: A meta-analysis

AIM: To conduct a meta-analysis evaluating the association between the peripheral blood neutrophil to lymphocyte ratio (NLR) and the outcome of patients with pancreatic cancer.METHODS: Studies evaluating the relationship between the peripheral blood NLR and outcome of patients with pancreatic cancer published up to May 2014 were searched using electronic databases, including PubMed, Web of Science, Embase and Ovid. A meta-analysis was performed to pool the hazard ratios (HRs) or odds ratios (ORs) and their 95% confidence intervals (CIs) using either a fixed-effects model or a random-effects model to quantitatively assess the prognostic value of NLR and its association with clinicopathological parameters.RESULTS: Eleven studies containing a total of 1804 patients were eligible according to our selection criteria, and combined hazard ratios indicated that high NLR was a poor prognostic marker for pancreatic cancer patients because it had an unfavorable impact on the overall survival (OS) (HR = 2.61, 95%CI: 1.68-4.06, P = 0.000) and cancer specific survival (HR = 1.66, 95%CI: 1.08-2.57, P = 0.021). Subgroup analysis revealed that high NLR was associated with poor OS in patients with mixed treatment (HR = 4.36, 95%CI: 2.50-7.61, P = 0.000), chemotherapy (HR = 2.08, 95%CI: 1.49-2.9, P = 0.000), or surgical resection (HR = 1.2, 95%CI: 1.00-1.44, P = 0.048). Additionally, high NLR was significantly correlated with tumor metastasis (OR = 1.69, 95%CI: 1.10-2.59, P = 0.016), poor tumor differentiation (OR = 2.75, 95%CI: 1.19-6.36, P = 0.016), poor performance status (OR = 2.56, 95%CI: 1.63-4.03, P = 0.000), high cancer antigen 199 (OR = 2.62, 95%CI: 1.49-4.60, P = 0.000), high C-reactive protein (OR = 4.32, 95%CI: 2.71-6.87, P = 0.000), and low albumin (OR = 3.56, 95%CI: 1.37-9.27, P = 0.009).CONCLUSION: High peripheral blood NLR suggested a poor prognosis for patients with pancreatic cancer, and it could be a novel marker of survival evaluation and could help clinicians develop therapeutic strategies for pancreatic cancer patients.

目的 探讨应用红细胞分布宽度(RDW)和中性粒细胞/淋巴细胞比值(NLR)评估原发性胆汁性胆管炎(PBC)患者肝损伤的临床价值。方法 2017年3月～2019年12月我院收治的PBC患者93例,其中Ⅰ/Ⅱ期(轻度组)63例,Ⅲ期(重度组)30例。使用血常规分析仪检测血液中性粒细胞和淋巴细胞绝对计数,计算NLR,采用激光电阻抗法检测RDW,应用多元Logistics回归分析影响肝损伤程度的因素,应用ROC曲线分析RDW和NLR评估肝损伤的价值。结果 重度组RDW和NLR显著大于轻度组【分别为(15.8±3.2)%对13.3±2.9)%和(2.1±0.4)对(1.5±0.3),P<0.05】;重度肝损伤组有饮酒史的比率(33.3%对7.9%)、血清GGT水平【(395.3±6.5)U/L对(189.2±6.1)U/L】 、血清ALP水平【(352.1±49.2)U/L对(281.0±46.9)U/L】、RDW≥14.8%的比率(70.0%对46.0%)和NLR≥1.8的比率(76.7%对41.3%)显著高于轻度肝损伤组(所有P<0.05);多因素分析显示,有饮酒史【OR(95%CI)为1.8(1.1～2.9)】、GGT≥293.1 U/L【OR(95%CI)为1.7(1.2～2.5)】、ALP≥327.6 U/L【OR(95%CI)为1.9(1.2～2.8)】、RDW≥14.8%【OR(95%CI)为1.9(1.2～2.8)】和NLR≥1.8【OR(95%CI)为1.7(1.3～2.2)】是严重肝损伤的独立危险因素;分别以RDW=14.8%和NLR=1.8为截断点,其联合诊断严重肝损伤的AUC为0.854,其灵敏度为86.7%,显著高于两指标中任一指标的评估,而特异性为71.4%,稍低于两指标的单一评判。结论 应用NLR评估PBC患者肝损伤程度具有一定的临床价值,其简单、易得,联合RDW可提高灵敏度,但特异性较差,两者联合应用的价值需要进一步探讨。     

Neutrophil to lymphocyte and platelet to lymphocyte ratio in patients with dipper versus non-dipper hypertension

Background: Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are associated with worse outcome in various diseases. Non-dipping blood pressure pattern is associated with higher cardiovascular mortality. The aim of this study was to explore the association between NLR and PLR in patients with dipper versus non-dipper hypertension.

Methods: The study included 166 patients with hypertension. Eighty-three patients (40 male, mean age: 49.1?±?10.5 years) had dipper hypertension, while 83 patients (41 male, mean age: 52.3?±?12.7 years) had non-dipper hypertension.

Results: Baseline demographic characteristics were similar in both groups. Patients with non-dipper hypertension had significantly higher NLR compared to dipper hypertension (2.3?±?0.9 versus 1.8?±?0.5, p?p?=?0.001). In univariate analysis, hyperlipidemia, smoking, presence of diabetes, PLR more than 107 and NLR more than 1.89 were among predictors of dipper and non-dipper status. In logistic regression analyses, only hyperlipidemia (odds ratio: 2.96, CI: 1.22–7.13) and PLR more than 107 (odds ratio: 2.62, CI: 1.13–6.06) were independent predictors of dipper and non-dipper status. A PLR of 107 or higher predicted non-dipper status with a sensitivity of 66.3% and specificity of 68.7%.

Conclusion: We demonstrated that patients with non-dipper hypertension had significantly higher NLR and PLR compared to dipper hypertension, which has not been reported previously. Moreover PLR more than 107 but not NLR was independent predictor of non-dipper status.     

急性冠状动脉综合征患者血清促肾上腺皮质激素和肾上腺皮质醇水平及其与短期预后的相关性分析

目的:探讨急性冠状动脉(冠脉)综合征(ACS)患者血清促肾上腺皮质激素(ACTH)和肾上腺皮质醇(Cor)水平及其与短期预后的相关性分析。方法:选取2016年2月至2018年8月在我院住院治疗的ACS患者189例,将患者分为不稳定性心绞痛(UAP)组(n=75)和急性心肌梗死(AMI)组(n=114),同期选取因胸痛住院治疗且行冠脉造影排除ACS者作为对照组(n=46)。对照组于入院即刻,ACS患者分别于入院即刻(T0)、6 h(T1)、1 d(T2)、3 d(T3)和7 d(T4)检测血清中ACTH和Cor水平,所有ACS患者出院后随访6个月,将患者分为主要不良心血管事件(MACE)亚组(n=46)和非MACE亚组(n=143)。MACE定义为全因死亡、急性心肌梗死、冠脉血运重建的复合终点。结果:与对照组T0时比较,UAP组T0~T3时和AMI组T0~T4时患者血清ACTH和Cor水平升高(P<0.05)。与对照组T0时比较,UAP组和AMI组患者T1~T4时血清ACTH和Cor水平呈先升高后降低,T2时最高(P<0.05)。与UAP组比较,AMI组患者T0~T4时血清ACTH和Cor水平升高(P<0.05);与对照组T0时比较,非MACE亚组T0~T3时和MACE亚组T0~T4时患者血清ACTH和Cor水平呈先升高后降低,T2时最高(P<0.05),与非MACE亚组比较,MACE亚组T0~T4时患者血清ACTH和Cor水平升高(P<0.05)。Cox风险比例回归分析结果显示,Gensini积分(HR=1.048,95%CI:1.016~1.082)、ACTH-T1(HR=1.038,95%CI:1.011~1.065)、ACTH-T2(HR=1.023,95%CI:1.002~1.044)、Cor-T1(HR=1.096,95%CI:1.032~1.164)和Cor-T2(HR=1.046,95%CI:1.012~1.081)是影响ACS患者发生MACE的风险因素。结论:ACS患者血清ACTH和Cor水平升高,且与患者短期预后有关,住院6 h和1 d时血清ACTH和Cor水平是患者发生MACE的风险因素。     

Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) were useful markers in assessment of inflammatory response and disease activity in SLE patients

Objective: Although there have been extensive investigations on neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and mean platelet volume (MPV) in many diseases, their roles in systemic lupus erythematosus (SLE) remain unclear. The purpose of the present study was to evaluate NLR, PLR, and MPV levels in adult SLE patients and explore their clinical significance.

Methods: A retrospective study involving 154 adult SLE patients and 151 healthy controls was performed. All clinical characteristics of the SLE patients were extracted from their medical records. NLR, PLR, and MPV levels between SLE patients and healthy controls were compared, and correlations between these indexes and clinical characteristics were analyzed.

Results: Increased NLR, PLR, and MPV were observed in SLE patients. NLR was positively correlated with C-reaction protein (r?=?0.509, p?<?0.01), erythrocyte sedimentation rate (r?=?0.610, p?<?0.01), and SLE Disease Activity Index (SLEDAI) scores (r?=?0.471, p?<?0.01). PLR was positively correlated with SLEDAI scores (r?=?0.44, p?<?0.01). SLE patients with nephritis had higher NLR and PLR levels than those without nephritis (p?<?0.01, p?=?0.03). In addition, an NLR level of 2.065 was determined as predictive cut-off value of SLE (sensitivity 74.7%, specificity 77.5%, AUC?=?0.828). Multiple regression analysis suggested that NLR was independently associated with SLE disease activity.

Conclusions: NLR and PLR could reflect inflammatory response and disease activity in SLE patients.
