Application of neutrophil-lymphocyte ratio and red blood cell distribution width in diabetes mellitus complicated with heart failure

BACKGROUND Accumulating clinical evidence has shown that diabetes mellitus(DM)is a serious risk factor for cardiovascular disorders and an important factor for adverse cardiovascular events.AIM To explore the value of the combined determination of the neutrophil-lymphocyte ratio(NLR)and red blood cell distribution width(RDW)in the early diagnosis and prognosis evaluation of DM complicated with heart failure(HF).METHODS We retrospectively analyzed clinical data on 65 patients with type 2 DM(T2DM)complicated with HF(research group,Res)and 60 concurrent patients with uncomplicated T2DM(control group,Con)diagnosed at Zhejiang Provincial People’s Hospital between January 2019 and December 2021.The NLR and RDW values were determined and comparatively analyzed,and their levels in T2DM+HF patients with different cardiac function grades were recorded.The receiver operating characteristic(ROC)curves were plotted to determine the NLR and RDW values(alone and in combination)for the early diagnosis of HF.The correlation between NLR and RDW with the presence or absence of cardiac events was also investigated.RESULTS Higher NLR and RDW levels were identified in the Res vs the Con groups(P<0.05).The NLR and RDW increased gradually and synchronously with the deterioration of cardiac function in the Res group,with marked differences in their levels among patients with grade II,III,and IV HF(P<0.05).ROC curve analysis revealed that NLR combined with RDW detection had an area under the curve of 0.915,a sensitivity of 76.9%,and a specificity of 100%for the early diagnosis of HF.Furthermore,HF patients with cardiac events showed higher NLR and RDW values compared with HF patients without cardiac events.CONCLUSION NLR and RDW were useful laboratory indicators for the early diagnosis of DM complicated with HF,and their joint detection was beneficial for improving diagnostic efficiency.Additionally,NLR and RDW values were directly proportional to patient outcomes.

Red cell distribution width-to-albumin ratio is a simple promising prognostic marker in acute cholangitis requiring biliary drainage

Background: It is crucial to assess the severity of acute cholangitis(AC). There are currently several prognostic markers. However, the accuracies of these markers are not satisfied. The present study aimed to investigate the predictive value of the red cell distribution width(RDW)-to-albumin ratio(RAR) for the prognosis of AC. Methods: We retrospectively evaluated consecutive patients diagnosed with AC between May 2019 and March 2022. RAR was calculated, and its predictive ability for in-hospital mortality, intensive care unit(ICU) admission, bacteremia, and the length of hospitalization were analyzed. Results: Out of 438 patients, 34(7.8%) died. Multivariate analysis showed that malignant etiology [odds ratio(OR) = 4.816, 95% confidence interval(CI): 1.936-11.980], creatinine(OR = 1.649, 95% CI: 1.095-2.484), and RAR(OR = 2.064, 95% CI: 1.494-2.851) were independent risk factors for mortality. When adjusted for relevant covariates, including age, sex, malignant etiology, Tokyo severity grading(TSG), Charlson comorbidity index, and creatinine, RAR significantly predicted mortality(adjusted OR = 1.833, 95% CI: 1.280-2.624). When the cut-off of RAR was set to 3.8, its sensitivity and specificity for mortality were 94.1% and 56.7%, respectively. Patients with an RAR of > 3.8 had a 20.9-fold(OR = 20.9, 95% CI: 4.9-88.6) greater risk of mortality than the remaining patients. The area under the curve value of RAR for mortality was 0.835(95% CI: 0.770-0.901), which was significantly higher than that of TSG and the other prognostic markers, such as C-reactive protein-to-albumin ratio, and procalcitonin-to-albumin ratio. Lastly, RAR was not inferior to TSG in predicting ICU admission, bacteremia, and the length of hospitalization. Conclusions: RAR successfully predicted the in-hospital mortality, ICU admission, bacteremia, and the length of hospitalization of patients with AC, especially in-hospital mortality. RAR is a promising marker that is more convenient than TSG and other prognostic markers for predicting the prognosis of patients with AC.

Red cell distribution width/platelet ratio estimates the 3-year risk of decompensation in Metabolic Dysfunction-Associated Steatotic Liver Disease-induced cirrhosis

BACKGROUND For compensated advanced chronic liver disease(cACLD)patients,the first decompensation represents a dramatically worsening prognostic event.Based on the first decompensation event(DE),the transition to decompensated advanced chronic liver disease(dACLD)can occur through two modalities referred to as acute decompensation(AD)and non-AD(NAD),respectively.Clinically Significant Portal Hypertension(CSPH)is considered the strongest predictor of decompensation in these patients.However,due to its invasiveness and costs,CSPH is almost never evaluated in clinical practice.Therefore,recognizing noninvasively predicting tools still have more appeal across healthcare systems.The red cell distribution width to platelet ratio(RPR)has been reported to be an indicator of hepatic fibrosis in Metabolic Dysfunction-Associated Steatotic Liver Disease(MASLD).However,its predictive role for the decompensation has never been explored.AIM In this observational study,we investigated the clinical usage of RPR in predicting DEs in MASLD-related cACLD patients.METHODS Fourty controls and 150 MASLD-cACLD patients were consecutively enrolled and followed up(FUP)semiannually for 3 years.At baseline,biochemical,clinical,and Liver Stiffness Measurement(LSM),Child-Pugh(CP),Model for End-Stage Liver Disease(MELD),aspartate aminotransferase/platelet count ratio index(APRI),Fibrosis-4(FIB-4),Albumin-Bilirubin(ALBI),ALBI-FIB-4,and RPR were collected.During FUP,DEs(timing and modaities)were recorded.CSPH was assessed at the baseline and on DE occurrence according to the available Clinical Practice Guidelines.RESULTS Of 150 MASLD-related cACLD patients,43(28.6%)progressed to dACLD at a median time of 28.9 months(29 NAD and 14 AD).Baseline RPR values were significantly higher in cACLD in comparison to controls,as well as MELD,CP,APRI,FIB-4,ALBI,ALBI-FIB-4,and LSM in dACLD-progressing compared to cACLD individuals[all P<0.0001,except for FIB-4(P:0.007)and ALBI(P:0.011)].Receiving operator curve analysis revealed RPR>0.472 and>0.894 as the best cut-offs in the prediction respectively of 3-year first DE,as well as its superiority compared to the other non-invasive tools examined.RPR(P:0.02)and the presence of baseline-CSPH(P:0.04)were significantly and independently associated with the DE.Patients presenting baseline-CSPH and RPR>0.472 showed higher risk of decompensation(P:0.0023).CONCLUSION Altogether these findings suggest the RPR as a valid and potentially applicable non-invasive tool in the prediction of timing and modalities of decompensation in MASLD-related cACLD patients.

Study on the packed volume and the void ratio of idealized human red blood cells using a ?nite-discrete element method

Numerical simulations are performed to examine the packing behavior of human red blood cells(RBCs). A combined ?nite-discrete element method(FDEM) is utilized, in which the RBCs are modeled as no-friction and no-adhesion solid bodies. The packed volume and the void ratio of a large number of randomly packed RBCs are clari?ed,and the effects of the RBC shape, the mesh size, the cell number, and the container size are investigated. The results show that the packed human RBCs with normal shape have a void ratio of 28.45%, which is slightly higher than that of the ?at or thick cells used in this study. Such information is bene?cial to the further understanding on the geometric features of human RBCs and the research on RBC simulations.

Red blood cell distribution width derivatives in alcohol-related liver cirrhosis and metabolic-associated fatty liver disease

BACKGROUND Looking for undiscovered blood markers of liver fibrosis and steatosis still remains an issue worth exploring.There are still plenty of unresolved issues related to the actual role of hematological indices as potential markers of liver function.AIM To study red blood cell distribution width(RDW),RDW-to-platelet ratio(RPR)and RDW-to-lymphocyte ratio(RLR) in alcohol-related liver cirrhosis(ALC) and metabolic-associated fatty liver disease(MAFLD).METHODS The study group was composed of 302 people:142 patients with ALC and 92 with MAFLD;68 persons were included as controls.RDW,RPR and RLR were measured in each person.Indirect and direct parameters of liver fibrosis were also assessed [aspartate transaminase to alkaline transaminase ratio,aspartate transaminase to platelet ratio index(APRI),fibrosis-4(FIB-4),gamma-glutamyl transpeptidase to platelet ratio(GPR),procollagen I carboxyterminal propeptide,procollagen Ⅲ aminoterminal propeptide,transforming growth factor-α,plateletderived growth factor AB,laminin].MELD score in ALC patients and nonalcoholic fatty liver disease(NAFLD) fibrosis score together with BARD score were obtained in the MAFLD group.The achieved results were compared to controls.Then a correlation between assessed markers was done.Diagnostic value of each investigated parameter and its suggested cut-off in the research group RESULTS RDW,RPR and RLR values turned out to be significantly higher in ALC and MAFLD groups compared to controls(ALC:P<0.0001;NAFLD:P<0.05,P<0.0001 and P<0.0001,respectively).RPR correlated positively with MELD score(P<0.01) and indirect indices of liver fibrosis(FIB-4 and GPR;P<0.0001) in ALC patients;negative correlations were found between PDGF-AB and both:RDW and RPR(P<0.01 and P<0.0001,respectively).RPR correlated positively with NAFLD fibrosis score and APRI(P<0.0001) in the MAFLD group;a positive relationship was observed between RDW and FIB-4,too(P<0.05).AUC values and suggested cut-offs for RDW,RPR and RLR in ALC patients were:0.912(>14.2%),0.965(>0.075) and 0.914(>8.684),respectively.AUC values and suggested cut-offs for RDW,RPR and RLR in MAFLD patients were:0.606(>12.8%),0.724(>0.047) and 0.691(>6.25),respectively.CONCLUSION RDW with its derivatives appear to be valuable diagnostic markers in patients with ALC.They can also be associated with a deterioration of liver function in this group.

Effects of“Moxibustion Serum”on Proliferation and Phenotypes of Tumor Infiltrating Lymphocytes

Tumor infiltrating lymphocytes (TIL) were cultured with “moxibustion serum”(MS), and the results were examined by flow cytometry. The results indicated that MS could enhance the proliferation of TIL,accelerate it to reach the exponential growth phase, and assist recombinant interleukin 2 (rIL-2) to enhance successively the percentage of CD3^+ positive cells, maintain the number of CD4^+ positive T cells, promote greatly the percentage of CD8^+ positive T cells among TILs, and reverse the CD4^+/CD8^+ ratio. Such cooperative effects rely on relative specificity of acupoints. It is suggested that MS is beneficial to the growth of TIL both in the aspects of proliferation and phenotypes.

EFFECT OF ELECTROACUPUNCTURE ON RED BLOOD CELL IMMUNE AND T-CELL SUBGROUP IN THE RAT

In the present study, the effect of electroacupuncture (EA) on immune system was observed in the rat by using micro- whole blood direct immunofluorescence staining assay to detect changes of the peripheral blood T lymphocyte subgroup and employing red blood cell (RBC) C 3b receptor- yeast rosette test and red blood cell-IC rosette test to analyze erythrocytic immune function. Results showed that after EA of “Zusanli" (ST 36), CD+ 4, RBC-C 3bRR and RBC-ICR in the peripheral blood of the normal rats increased significantly while CD+ 8 had no any considerable changes and a positive correlation between CD+ 4 and RBC-C 3bRR was found. In immunosuppression model rats, the values of CD+ 4 and RBC-C 3bRR were obviously lower than those of the normal control group while CD+ 8 had no any striking changes; but after EA treatment, there were no evident differences between EA group and normal control group in the above-mentioned indexes. There were also no any significant differences between non-acupoint group and normal control group in those indexes. Results suggest that EA of “Zusanli" (ST 36) can raise T cell immune function and RBC adhesion function in both normal rats and immunosuppression model rats, both of which present a positive correlation.

目的:探讨外周血红细胞分布宽度(RDW)、平均血小板容积(MPV)、中性粒细胞与淋巴细胞比值(NLR)、血小板与淋巴细胞比值(PLR)及淋巴细胞与单核细胞比值(LMR)在肺癌中的诊断价值。方法:选取113例肺癌患者(肺癌组)和113例体检健康者(对照组)。检测两组全血细胞并计算NLR、PLR、MPV。绘制受试者工作特征(ROC)曲线分析RDW、MPV、NLR、LMR和PLR对肺癌的诊断价值。结果:肺癌组患者RDW、NLR、PLR和MPV值高于对照组,LMR低于对照组(均P<0.05)。RDW、MPV、NLR、PLR和LMR在肺癌组不同病理学亚组间比较差异无统计学意义(均P>0.05)。RDW、MPV、NLR、PLR、LMR的曲线下面积(AUC)分别为0.600、0.629、0.882、0.788、0.868,而五项联合诊断肺癌的AUC(0.933)更高(均P<0.05)。结论:肺癌患者外周血RDW、NLR、PLR和MPV升高,LMR降低,五项联合对肺癌的诊断价值较高。

血清3项炎症指标对肛周脓肿部位及严重程度的诊断效能

目的:探讨超敏C反应蛋白(hs-CRP)、白细胞(WBC)、中性粒细胞与淋巴细胞比值(NLR)对肛周脓肿的诊断效能。方法:纳入146例肛周脓肿患者作为病例组;同期130例健康体检者作为对照组。检测2组受试者血清炎症指标变化。应用受试者工作特征(ROC)曲线评估hs-CRP、WBC、NLR对肛周脓肿部位及严重程度的诊断效能。结果:高位肛周脓肿的发生与hs-CRP、WBC、中性粒细胞百分数(NEUT%)、CRP、NLR均成正相关(P<0.05),与对照组、低位脓肿组患者比较,上述指标的差异均有统计学意义(P<0.05)。hs-CRP、CRP、WBC、NLR、CRP+WBC+NLR、hs-CRP+WBC+NLR诊断高位脓肿与低位脓肿的曲线下面积(AUC值)分别为0.680、0.679、0.619、0.648、0.673、0.679。结论:hs-CRP对肛周脓肿诊断及其严重程度评估均具有较高的预测价值,可在肛周脓肿早期阶段快速诊断,值得临床推广。

RDW、HCT、NLR水平与急性心力衰竭患者病情严重程度的相关性

目的:分析红细胞体积分布宽度(RDW)、血细胞比容(HCT)、中性粒细胞/淋巴细胞比值(NLR)水平与急性心力衰竭患者病情严重程度的相关性。方法:选取2021年8月至2023年3月该院收治的128例急性心力衰竭患者为研究组,另选取同期本院128名健康体检者为对照组。比较两组、不同美国纽约心脏病协会心功能分级患者RDW、HCT、NLR水平,采用Spearman相关性分析RDW、HCT、NLR水平与急性心力衰竭患者病情严重程度的相关性。结果:研究组RDW、NLR水平均高于对照组,HCT水平低于对照组,差异有统计学意义(P<0.05);心功能分级Ⅳ级患者RDW、NLR水平均高于Ⅲ级、Ⅱ级患者,且Ⅲ级患者高于Ⅱ级患者,心功能分级Ⅳ级患者HCT水平均低于Ⅲ级、Ⅱ级患者,且Ⅲ级患者低于Ⅱ级患者,差异有统计学意义(P<0.05);Spearman相关性分析结果显示,RDW、NLR水平与急性心力衰竭患者病情严重程度均呈正相关(r>0,P<0.05),HCT水平与急性心力衰竭患者病情严重程度呈负相关(r<0,P<0.05)。结论:RDW、NLR水平与急性心力衰竭患者病情严重程度均呈正相关,HCT水平与急性心力衰竭患者病情严重程度呈负相关。
