The value of immune inflammatory index in predicting the therapeutic efficacy of neoadju-vant chemoradiotherapy for esophageal squamous cell carcinoma / 中华消化外科杂志

Objective:To investigate the value of immune inflammatory index in predic-ting the therapeutic efficacy of neoadjuvant chemoradiotherapy for esophageal squamous cell carci-noma (ESCC).Methods:The retrospective case-control study was conducted. The clinicopatholo-gical data of 163 patients with ESCC who were admitted to Zhongshan Hospital of Fudan University from December 2015 to December 2020 were collected. There were 135 males and 28 females, aged (62±8)years. All 163 patients underwent neoadjuvant chemoradiotherapy and radical resection for ESCC. Observation indicators: (1) relationship between immune inflammatory index and clinical characteristic in patients; (2) relationship between immune inflammatory index and efficacy of neoadjuvant chemoradiotherapy in patients; (3) influencing factor analysis for pathologic complete response and good response of tumor regression grade after neoadjuvant chemoradiotherapy; (4) efficiency of immune inflammatory index in predicting efficacy of neoadjuvant chemoradiotherapy. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and comparison between groups was conducted using chi-square test. Comparison of ordinal data was conducted using the rank sum test. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value. Univariate and multi-variate analyses were conducted using the Logistic regression model. The area under the curve (AUC) of ROC curve was used to evaluate the efficiency of predictive model. Results:(1) Relationship between immune inflammatory index and clinical characteristic in patients. ① Optimal cut-off value of systemic immune-inflammation index (SII), neutrophil-lymphocyte ratio (NLR), platelet-lympho-cyte ratio (PLR). Results of ROC curve analysis showed that the AUC of SII, NLR, PLR in predicting efficacy of neoadjuvant chemoradiotherapy for patients with ESCC was 0.70(95% confidence interval as 0.61?0.77), 0.78(95% confidence interval as 0.69?0.84), 0.79(95% confidence interval as 0.70?0.85), respectively, with the maximum value of Youden index and the optimal cut-off value as 0.25, 0.32, 0.52 and 446×10 9/L, 2.09, 138. ② Relationship between SII, NLR, PLR and clinical charac-teristic in patients. According to the optimal cut-off value of SII, NLR, PLR, all 163 patients were divided into cases with SII <446×10 9/L as 99, cases with SII ≥446×10 9/L as 64, cases with NLR <2.09 as 107, cases with NLR ≥2.09 as 56, cases with PLR<138 as 88, cases with PLR ≥138 as 75, respectively. There was a significant difference in clinical N staging of tumor in patients with SII <446×10 9/L and SII ≥446×10 9/L ( P<0.05). There were significant differences in clinical N staging and clinical TNM staging of tumor in patients with NLR<2.09 and NLR≥2.09 ( P<0.05). (2) Relationship between immune inflammatory index and efficacy of neoadjuvant chemoradiotherapy in patients. Of 163 patients undergoing neoadjuvant chemoradiotherapy, there were 54 cases with pathologic complete response and 109 cases without pathologic complete response, 94 cases with good response of tumor regression grade and 69 cases with poor response of tumor regression grade. Of the 54 patients with pathologic complete response, cases with SII <446×10 9/L and SII ≥446×10 9/L, cases with NLR <2.09 and NLR ≥2.09, cases with PLR <138 and PLR ≥138 before neoadjuvant chemoradiotherapy were 42 and 12, 47 and 7, 48 and 6, respectively. The above indicators were 57 and 52, 60 and 49, 40 and 69 in the 109 cases without pathologic complete response. There were significant differences in the above indicators between patients with pathologic complete response and without pathologic complete response ( χ2=9.83, 16.39, 39.60, P<0.05). Of the 94 cases with good response of tumor regression grade, cases with SII <446×10 9/L and SII ≥446×10 9/L, cases with NLR <2.09 and NLR ≥2.09, cases with PLR <138 and PLR ≥138 before neoadjuvant chemoradiotherapy were 59 and 35, 78 and 16, 56 and 38, respectively. The above indicators were 40 and 29, 29 and 40, 32 and 37 in the 69 cases with poor response of tumor regression grade. There was no significant difference in the SII and PLR ( χ2=0.38, 2.79, P>0.05) and there was a significant difference in the NLR ( χ2=29.59, P<0.05) between patients with good response of tumor regression grade and poor response of tumor regre-ssion grade. (3) Influencing factor analysis for pathologic complete response and good response of tumor regression grade after neoadjuvant chemoradiotherapy. Results of multivariate analysis showed that PLR <138 before neoadjuvant chemoradiotherapy was an independent protective factor for pathologic complete response in ESCC patients undergoing neoadjuvant chemoradiotherapy ( odds ratio=1.98, 95% confidence interval as 1.56?2.51, P<0.05) and NLR <2.09 before neoadjuvant chemo-radiotherapy was an independent protective factor for good response of tumor regression grade ( odds ratio=2.50, 95% confidence interval as 1.40?4.46, P<0.05). (4) Efficiency of immune inflam-matory index in predicting efficacy of neoadjuvant chemoradio-therapy. The AUC of PLR <138 before neoadjuvant chemoradiotherapy in predicting pathologic complete response of ESCC patients undergoing neoadjuvant chemoradiotherapy was 0.79(95% confidence interval as 0.64?0.87, P<0.05), with the sensitivity, specificity and Youden index as 0.89, 0.63 and 0.52, respectively. The AUC of NLR <2.09 before neoadjuvant chemoradiotherapy in predic-ting good response of tumor regression grade of ESCC patients undergoing neoadjuvant chemoradio-therapy was 0.76 (95% confidence interval as 0.64?0.81, P<0.05), with the sensitivity, specificity and Youden index as 0.83, 0.58 and 0.41, respectively. Conclusion:The PLR<138 and NLR <2.09 before neoadjuvant chemoradiotherapy are independent protective factors for the pathologic complete response and good response of tumor regression grade, respectively, of ESCC patients undergoing neoadjuvant chemoradiotherapy, and both of them can predict the curative effect of neoadjuvant chemoradiotherapy well.

Preoperative NLR-PLR may help to predict the prognosis of UTUC patients / 现代泌尿外科杂志

【Objective】 To investigate the predictive value of preoperative platelet/lymphocyte ratio (PLR) and neutrophil/lymphocyte ratio (NLR) (NLR-PLR) in peripheral blood for the prognosis of patients with upper urinary tract urothelial carcinoma (UTUC) undergoing radical surgery. 【Methods】 The clinical data of 104 UTUC patients who underwent radical nephroureterectomy plus bladder sleeve resection in our hospital during Jan.2015 and Dec.2020 were retrospectively analyzed. The receiver operating characteristic (ROC) curve was drawn according to NLR and PLR, the optimal cut-off values of NLR and PLR were calculated, and NLR-PLR was determined accordingly. The patients were divided into NLR-PLR group 1 (PLR ≥161.46 and NLR≥ 2.51) and NLR-PLR group 0 (remaining patients). Chi-square test was used for comparison between groups, and the Kaplan-Meier method was used to draw survival curves. According to the Cox univariate and multivariate risk regression models, the risk factors for decreased overall survival (OS) were determined. 【Results】 The optimal cut-off values of PLR and NLR were 161.46 and 2.51, respectively. There were 74 patients in the NLR-PLR group 0 and 30 in the NLR-PLR group 1. Cox multivariate regression analysis showed that T stage, maximum tumor diameter and NLR-PLR were independent risk factors for reduced OS (P<0.05). 【Conclusion】 Preoperative NLR-PLR is a potential predictor of the prognosis of UTUC patients. Higher NLR-PLR is associated with poorer prognosis.

Prognostic value of platelet-to-lymphocyte ratio in prostate cancer patients:a meta analysis / 现代泌尿外科杂志

【Objective】 To evaluate the value of platelet-to-lymphocyte ratio (PLR) in the prognosis of prostate cancer. 【Methods】 Relevant studies were searched in CNKI, Wanfang, CBM, VIP, PubMed, Web of Science, Cochrane Library and Embase databases from inception to Dec.2021. The literature was screeded, data were extracted, and the quality was evaluated according to the inclusion and exclusion criteria. A meta-analysis by using the hazard risk (HR) and 95% confidence interval (CI) was adopted to assess the prognostic value of PLR. The data were analyzed with STATA 16.0 software. 【Results】 A total of 10 studies were included, involving 1 802 patients. For patients with high level of PLR, the overall survival (OS) (HR=1.70, 95%CI:1.25-2.30, P=0.001) and disease-free survival (DFS)(HR=1.44, 95%CI:1.15-1.81, P=0.002) were significantly shorter. 【Conclusion】 PLR is an independent risk factor affecting the long-term prognosis of prostate cancer patients. Pretreatment detection of PLR is meaningful in determining the prognosis.

Correlation of preoperative peripheral blood neutrophil-lymphocyte ratio and blood platelet-lymphocyte ratio and immune indexes with the prognosis of cervical cancer patients / 肿瘤研究与临床

Objective:To evaluate the value of preoperative peripheral blood neutrophil-lymphocyte ratio (NLR) and blood platelet-lymphocyte ratio (PLR) and immune indexes in the evaluation of the prognosis of cervical cancer patients.Methods:The clinical data of 283 patients with cervical cancer who underwent radical surgery in Shanxi Province Cancer Hospital from May 2017 to September 2018 were retrospectively analyzed, and 100 healthy people who underwent physical examination during the same period were collected as the healthy control group. Test results of blood cells and immune cells expressions of all subjects were collected. Peripheral blood NLR and PLR of cervical cancer patients, people in the healthy control group and cervical cancer patients with different pathological characteristics were compared. Kaplan-Meier method was used to make survival analysis and Cox regression risk model was used to analyze the factors influencing the prognosis of patients with cervical cancer.Results:The preoperative peripheral blood NLR and PLR in patients with cervical cancer was higher than that of the healthy control group (NLR: 2.53±1.35 vs. 2.00±1.21, t = 5.35, P < 0.001; PLR: 163±57 vs.144±38, t = 4.71, P = 0.006). Pathological results showed that there were no statistically significant differences in NLR and PLR in peripheral blood of cervical cancer patients with different pathological types, tumor diameter, vascular invasion, and nerve invasion (all P > 0.05), while there were statistically significant differences in NLR and PLR in peripheral blood of cervical cancer patients with different clinical staging and muscle wall invasion (all P < 0.05). When the proportions of the expression levels of preoperative CD3 positive cells, CD4 positive cells, CD8 positive cells, CD19 positive cells, CD56 positive cells, and CD127 positive cells were 60%-85%, 30%-40%, < 25%, 8%-15%, 15%-25% and < 5%, respectively, the overall survival of cervical cancer patients was the best. Univariate analysis showed that pathological type, clinical staging, vascular invasion, preoperative NLR, preoperative PLR,CD3 positive cells, CD4 positive cells, CD8 positive cells, CD19 positive cells, CD56 positive cells and CD127 positive cells were influencing factors of the overall survival of cervical cancer patients (all P < 0.05). Multivariate analysis showed that clinical staging, vascular invasion, preoperative NLR, preoperative PLR, and preoperative CD4 positive cells were independent influencing factors for the overall survival of cervical cancer patients (all P < 0.05). Conclusions:Preoperative high NLR and PLR in peripheral blood have a certain impact on the clinicopathological characteristics and poor prognosis of cervical cancer patients. When the immune cells in peripheral blood are in dynamic balance, the prognosis of cervical cancer patients is the best.

Predictive value of blood platelet-lymphocyte ratio and neutrophil-lymphocyte ratio in the therapeutic efficacy of neoadjuvant therapy for breast cancer patients / 肿瘤研究与临床

Objective:To investigate the predictive value of the changes of platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) in the therapeutic efficacy of the neoadjuvant treatment for breast cancer.Methods:The clinical data of 72 breast cancer patients who received neoadjuvant therapy in Nantong Tumor Hospital between February 2020 and January 2022 were retrospectively analyzed and the changes of PLR and NLR before and after neoadjuvant therapy were also analyzed. The receiver operating characteristic (ROC) curves were used to assess the predictive value of PLR, NLR and their changes in pathological complete remission (pCR) after neoadjuvant therapy.Results:The area under the ROC curve of PLR and NLR before the treatment, the difference in PLR before and after the treatment (ΔPLR), the difference in NLR before and after the treatment (ΔNLR) in predicting pCR was 0.520, 0.505,0.724 and 0.686,and the corresponding cut-off value was 269.231, 2.559, -2.840 and -1.457; the patients were divided into high and low groups according to the cut-off values. NLR before the treatment was not correlated with clinicopathological characteristics (all P > 0.05),while PLR before the treatment was correlated with tumor size ( P = 0.029), and ΔPLR was correlated with progesterone receptor expression ( P = 0.025), human epidermal growth factor receptor 2 (HER2) expression ( P < 0.001), molecular subtype ( P < 0.001), N stage ( P = 0.002), clinical stage ( P = 0.002) and treatment modality ( P < 0.001). ΔNLR was associated with HER2 expression ( P = 0.002), molecular subtype ( P = 0.024), tumor size ( P = 0.007), neural invasion ( P = 0.006), N stage ( P = 0.006), clinical stage ( P = 0.016) and treatment modality ( P = 0.014). ΔPLR and ΔNLR were influencing factors for patients achieving pCR after neoadjuvant therapy (all P < 0.05). Conclusions:Stage Ⅲ invasive breast cancer patients with higher ΔPLR and ΔNLR after neoadjuvant therapy have better prognosis.

VASOplegia is Predicted by Preoperative Platelet?LEucocyte conGlomerate Indices in Cardiac Surgery (VASOPLEGICS): A Retrospective Single?Center Study

Background:Post?cardiotomy vasoplegia syndrome (VS) is often linked to an exaggerated inflammatory response to cardiopulmonary bypass (CPB). At the same time, the prognostic role of platelet?leucocyte indices (PLIs) and leucocyte indices (LIs), (platelet?lymphocyte ratio [PLR], systemic immune?inflammation index [SII = platelet neutrophil/lymphocyte], aggregate index of systemic inflammation [AISI = platelet monocyte neutrophil/lymphocyte], and neutrophil?lymphocyte ratio [NLR], systemic inflammation response index [SIRI = monocyte neutrophil/lymphocyte), respectively] has been recently described in diverse inflammatory settings. Methods: The retrospective study was conducted to evaluate the VS predictive performance of PLIs and LIs in 1,045 adult patients undergoing elective cardiac surgery at a tertiary care center. VS was defined by mean blood pressure <60 mmHg, low systemic vascular resistance (SVRI <1,500 dynes.s/cm 5/m2 ), a normal or high CI (>2.5 L/min/m2 ), and a normal or reduced central filling pressure despite high?dose vasopressors. Results: About 205 (19.61%) patients developed VS postoperatively. On univariate analysis, age, diabetes, dialysis?dependent renal failure, preoperative congestive heart failure (CHF), the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, ejection fraction, NLR, PLR, SII, SIRI, AISI, CPB, and aortic cross clamp (ACC) duration, packed red blood cell (PRBC) transfusion, and time?weighted average blood glucose predicted VS. Subsequent to the multivariate analysis, the predictive performance of EuroSCORE II (OR: 3.236; 95% CI: 2.345–4.468; P < 0.001), CHF (OR: 1.04; 95% CI: 1.02–1.06; P = 0.011), SII (OR: 1.09; 95% CI: 1.02–1.18; P = 0.001), AISI (OR: 1.11; 95% CI: 1.05–1.17; P < 0.001), PRBC (OR: 4.747; 95% CI: 2.443–9.223; P < 0.001), ACC time (OR: 1.003; 95% CI: 1.001–1.005; P = 0.004), and CPB time (OR: 1.016; 95% CI: 1.004–1.028; P = 0.001) remained significant. VS predictive cut?offs of SII and AISI were 1,045 1045×109 /mm3 and 137532×109 /mm3 , respectively. AISI positively correlated with the postoperative vasoactive?inotropic score (R = 0.718), lactate (R = 0.655), mechanical ventilation duration (R = 0.837), and ICU stay (R = 0.757). Conclusions: Preoperative elevated SII and AISI emerged as independent predictors of post?cardiotomy VS.

Relationship of inflammatory and metabolic parameters in adolescents with PCOS: BMI matched case-control study

ABSTRACT Objective: Polycystic ovary syndrome (PCOS) begins in adolescence and has cardiovascular and metabolic components in later years. Cystatin C and high-sensitivity C-reactive protein (hs-CRP) levels and neutrophil-lymphocyte and platelet-lymphocyte ratios are associated with metabolic and inflammatory events. Here, we evaluated inflammatory and metabolic parameters in normal and overweight adolescents with PCOS. Materials and methods: This prospective case-control study enrolled 90 adolescents with PCOS and 100 matched by age and BMI healthy adolescents classified as either normal weight (NW) and overweight (OW). Groups were compared based on inflammatory and metabolic parameters (serum cystatin C, hs-CRP, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lipids, fasting blood glucose-insulin (FBG-FI), HOMA-IR levels, waist circumference [WC], and waist-hip ratio [WHR]). The relationship between the parameters were compared and predictive abilities were evaluated. Results: Cystatin C, hs-CRP, NLR, triglyceride (TG), FBG-FI, HOMA-IR, WC, and WHR were significantly higher in those with PCOS. The NW PCOS group had significantly higher TG, cystatin C, hs-CRP, and NLR versus OW controls. The highest HOMA-IR values were observed in OW PCOS (p < .05). Cystatin C and hs-CRP sensitivity and specificity were significant (p < 0.05). Cystatin C and hs-CRP were positively correlated with other metabolic parameters. Conclusion: Independent of BMI, inflammatory and metabolic parameters are significantly higher in adolescents with PCOS compared to controls and even worse in those who are also OW. Therefore, adolescents with PCOS should be encouraged to maintain healthy lifestyles and weights to avoid metabolic risks. Hs-CRP and cystatin C could be promising markers to predictive of future metabolic risks.

Objective:To investigate the correlations between albumin globulin ratio (AGR) , platelet lymphocyte ratio (PLR) , neutrophil lymphocyte ratio (NLR) and efficacy of chemotherapy for patients with metastatic colorectal cancer (mCRC) .Methods:The clinical data of 107 mCRC patients who were treated at the First Hospital of Shanxi Medical University for chemotherapy from January 2016 to September 2020 were selected, and the values of AGR, NLR and PLR before chemotherapy and after 3 cycles of chemotherapy were collected for retrospective analysis. After 3 cycles, patients were divided into three groups according to efficacy evaluation: partial response (PR) group, stable disease (SD) group and progressive disease (PD) group. The changes of AGR, PLR and NLR values before and after chemotherapy, and the relationships between the degrees of changes and the therapeutic effects were analyzed.Results:There were 18 cases in the PR group, 53 cases in the SD group and 36 cases in the PD group. There were no significant differences in age, sex, distant metastasis site, cancer site, T stage and N stage among the three groups ( F=0.33, P=0.721; χ2=2.94, P=0.230; χ2=2.34, P=0.674; χ2=0.80, P=0.669; χ2=5.68, P=0.224; χ2=2.06, P=0.375) . The AGR, PLR and NLR values before chemotherapy in the PR group were 1.57±0.19, 180.05±102.77 and 5.19 (4.50, 5.83) , and they were 1.45±0.23, 115.81±55.79 and 1.83 (1.06, 2.84) after chemotherapy, with statistically significant differences ( t=2.32, P=0.033; t=2.84, P=0.011; Z=-2.94, P=0.003) . In the SD group, AGR, PLR and NLR values before chemotherapy were 1.66 (1.40, 1.77) , 158.18 (103.81, 236.26) , 2.41 (1.75, 4.07) , and they were 1.35 (1.15, 1.60) , 123.85 (94.86, 176.44) , 1.49 (1.27, 2.33) after chemotherapy, with statistically significant differences ( Z=-4.51, P<0.001; Z=-3.31, P=0.001; Z=-3.90, P<0.001) . The AGR, PLR and NLR values in the PD group before chemotherapy were 1.60 (1.48, 1.87) , 122.07 (77.14, 175.72) , 2.37 (1.28, 4.20) , and they were 1.26 (1.08, 1.40) , 176.39 (139.89, 280.64) and 4.71 (3.71, 6.96) after chemotherapy, with statistically significant differences ( Z=-4.49, P<0.001; Z=-3.42, P=0.001; Z=-4.18, P<0.001) . The differences in AGR ( OR=3.66, 95% CI: 1.29-10.39, P=0.015) , PLR ( OR=0.99, 95% CI: 0.99-1.00, P<0.001) and NLR ( OR=0.59, 95% CI: 0.49-0.70, P<0.001) before and after chemotherapy were related to clinical efficacy. The greater the difference of AGR, the worse the short-term efficacy. The greater the difference of PLR and NLR, the better the short-term efficacy. The correlation between the changes in AGR, PLR and NLR before and after treatment and the clinical efficacy was sorted in descending order Δ NLR>Δ PLR>Δ AGR ( r=-0.68, P<0.001; r=-0.51, P<0.001; r=0.25, P=0.009) . Conclusion:The changes in the levels of AGR, NLR and PLR before and after chemotherapy are correlated with the short-term efficacy of mCRC, and it has certain significance for monitoring the curative effects of patients and further optimizing the treatment plan.

Comparison of nonspecific inflammatory markers in endometrial cancer and hyperplasia

SUMMARY OBJECTIVE: This study aims to analyze inflammatory markers among patients with endometrial cancer, hyperplasia with atypia/endometrial intraepithelial neoplasia, hyperplasia without atypia, and normal controls, thus observing the stage at which inflammation becomes the most significant. METHODS: A total of 444 patients who had endometrial sampling were included in the study (endometrial cancer, n=79; endometrial hyperplasia with atypia/endometrial intraepithelial neoplasia, n=27; endometrial hyperplasia without atypia, n=238; and normal controls, n=100). Neutrophil count, lymphocyte count, platelet count, platelet distribution width, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, CA-125, and endometrial thickness of the patients were recorded. RESULTS: Comparing the groups for neutrophil count, the hyperplasia with atypia group had higher values compared with both the hyperplasia without atypia group and the control group (p=0.003). When compared for the lymphocyte count, the hyperplasia with atypia group had lower values compared with the control group (p=0.014). Neutrophil/lymphocyte ratio of the hyperplasia with atypia group was higher than all other groups, and neutrophil/lymphocyte ratio of the cancer group was higher than the control group (p=0.001). Platelet count, mean platelet volume, platelet distribution width, and platelet/lymphocyte ratio values were not significantly different among groups (p>0.05). CONCLUSIONS: Considering the inflammatory markers, the most prominent result was that the hyperplasia with atypia group had neutrophilia, lymphopenia, and increased neutrophil/lymphocyte ratio compared with other groups.

Association of neutrophil-lymphocyte ratio and platelet-lymphocyte ratio with diabetic kidney disease among adult patients with type 2 diabetes mellitus: A meta-analysis of observational studies

@#<p style="text-align: justify;"><strong>Objective:</strong> This meta-analysis aimed to evaluate the association of neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) with the presence of diabetic kidney disease (DKD) among adult patients with Type 2 diabetes mellitus (T2DM).</p><p style="text-align: justify;"><strong>Methods:</strong> A systematic search of articles was performed in various databases. Studies must have fulfilled the following criteria for inclusion: 1) Randomized controlled trial or observational study; 2) Included adults diagnosed with T2DM; 3) Reported data associating NLR or PLR with the presence of DKD; and 4) Controlled for confounders using logistic regression. Data analysis was performed using Review Manager 5.4 software. The estimates were derived using the generic inverse variance method and pooled using the random effects model.

OBJECTIVE: This study aimed to analyze the relationship of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and monocyte-lymphocyte ratio (MLR) with clinicopathological characteristics of patients with differentiated thyroid cancer (DTC). METHODS: This retrospective study included 390 patients with DTC who had complete blood cell counts available at the time of surgery. NLR, PLR, and MLR were calculated, and the risk of cancer-related death, structural recurrence, and response to therapy were assessed using the eighth edition of the tumor-node-metastasis classification, American Thyroid Association (ATA) Risk Stratification System, and ATA Response to Therapy Reclassification, respectively. RESULTS: PLR was higher in patients with distant metastasis than in those without (133.15±43.95 versus 119.24±45.69, p=0.0345) and lower in patients with disease-free status (117.72±44.70 versus 131.07±47.85, p=0.0089) than in those who experienced persistent disease or death. Patients aged ≥55 years had a higher MLR than those aged <55 years (0.26±0.10 versus 0.24±0.12, p=0.0379). Higher MLR (odds ratio [OR]: 8.775, 95% confidence interval [CI]: 1.532-50.273, p=0.0147), intermediate ATA risk (OR: 4.892, 95% CI: 2.492-9.605, p≤0.0001), and high ATA risk (OR: 5.998, 95% CI: 3.126-11.505, p≤0.0001) were risk factors associated with active disease. NLR was not significantly different among the studied variables. Receiver operating characteristic curve cut-off values for NLR, PLR, and MLR were able to differentiate distant metastasis from lymph node metastasis (NLR>1.93: 73.3% sensitivity and 58.7% specificity, PLR>124.34: 86.7% sensitivity and 69.2% specificity, MLR>0.21: 80% sensitivity and 45.2% specificity). CONCLUSION: Cut-off values of NLR, PLR, and MLR differentiated distant metastasis from lymph node metastasis with good sensitivity and accuracy. PLR was associated with disease-free status and it was higher in DTC patients with distant metastasis, persistent disease, and disease-related death. MLR was a risk factor for active disease.

Assessment of inflammatory markers in otosclerosis patients / Avaliação de marcadores de inflamação em pacientes com otosclerose

Abstract Introduction Otosclerosis is an idiopathic disease characterized by new bone formation in foci of the human otic capsule. It is more common in Caucasian populations; affecting females twice as often as males. Its etiopathogenesis has not yet been fully elucidated. Objective The aim of this study was to investigate the relationship between otosclerosis and white blood cell and thrombocyte counts, mean platelet volume, neutrophil lymphocyte ratio, and the platelet lymphocyte ratio. Methods This retrospective case-control study was conducted in the outpatient clinic Mustafa Kemal University, in the department of otolaryngology, between 2015 and 2018. A total of 30 patients with an established diagnosis of otosclerosis were compared to a control group of 30 healthy subjects, matched for age, gender and body mass index. The white blood cell, thrombocyte, mean platelet volume, neutrophil lymphocyte ratio and platelet lymphocyte ratio values were calculated for all participants. Results There was no statistically significant difference between the groups with respect to age, gender, or body mass index, or for the mean neutrophil lymphocyte ratio, platelet lymphocyte ratio, white blood cell, or thrombocyte values (p > 0.05). A statistically significant difference was determined between the groups for the mean platelet volume values. The mean platelet volume values were lower in the otosclerotic patients (p = 0.047). Conclusion These results show that neutrophil lymphocyte ratio, platelet lymphocyte ratio, white blood cell and thrombocytes should not be used to predict otosclerosis, but suggest that mean platelet volume may be a negative predictive marker.

Resumo Introdução A otosclerose é uma doença idiopática caracterizada por neoformação óssea em focos da cápsula ótica humana. É mais comum em populações caucasianas, afeta o sexo feminino numa taxa 2 vezes maior do que o masculino. A etiopatogenia ainda não foi totalmente elucidada. Objetivo Investigar a relação entre otosclerose e taxa de glóbulos brancos, plaquetas, volume plaquetário médio, relação neutrófilos-linfócitos e relação plaquetas-linfócitos. Método Estudo retrospectivo de caso-controle feito no ambulatório da Mustafa Kemal University, Departamento de Otorrinolaringologia, entre 2015 e 2018. Foram comparados 30 pacientes com diagnóstico estabelecido de otosclerose com um grupo controle de 30 indivíduos saudáveis, pareados por idade, sexo e índice de massa corpórea. Os valores de glóbulos brancos, plaquetas, volume plaquetário médio, relação neutrófilos-linfócitos e relação plaquetas/linfócitos foram calculados para todos os participantes. Resultados Não houve diferença estatisticamente significante entre os grupos em relação a idade, sexo ou índice de massa corpórea, ou em relação aos valores médios de relação neutrófilos-linfócitos, relação plaquetas/linfócitos, valores de glóbulos brancos e plaquetas (p > 0,05). Uma diferença estatisticamente significante foi observada entre os grupos em termos de valores médios de volume plaquetário médio. Os valores de volume plaquetário médio foram menores nos pacientes com otosclerose (p = 0,047). Conclusão A relação plaquetas/linfócitos, a relação plaquetas/linfócitos, os valores de glóbulos brancos e plaquetas não podem ser usados para predizer a otosclerose, mas sugerem que o volume plaquetário médio possa ser um marcador preditivo negativo.

Neutrophil-lymphocyte ratio in catatonia

Abstract Background There is growing evidence of subclinical inflammation in mental disorders. Objective The aim of this study was to investigate frequency of symptoms of catatonia and the newly diagnosed subclinical inflammatory markers which are neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR), monocyte/lymphocyte (MLR) ratios in catatonia patients due to mental disorders. Methods: Patients who were admitted to psychiatry clinic with the diagnosis of catatonia according to DSM 5 in the last two years and equal number of control group were included in this retrospective study. Univariate analysis of covariance controlled for possible confounders was used to compare NLR, PLR, MLR ratios between patients and the control group. Results A total of 34 catatonia patients and 34 healthy controls were included in the study. Patients' mean age was 30.88 + 13.4. NLR value was significantly higher in the patient group than control group. There was no significant difference between the patients and control group according to PLR, MLR values. Discussion The presence of subclinical inflammation in catatonic syndrome due to mental disorders should be considered. Subclinical inflammation that was observed in numerous mental disorders continues in catatonia due to mental disorders. Large-scale studies are needed to determine the role of inflammation in catatonia.

Neutrophil/lymphocyte and platelet/lymphocyte ratios as potential markers of disease activity in patients with Ankylosing spondylitis: a case-control study

Abstract Background: The neutrophil/ lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) have the potential to be inflammatory markers that reflect the activity of many inflammatory diseases. The aim of this study was to evaluate the NLR and PLR as potential markers of disease activity in patients with ankylosing spondylitis. Methods: The study involved 132 patients with ankylosing spondylitis and 81 healthy controls matched in terms of age and gender. Their sociodemographic data, disease activity scores using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), erythrocyte sedimentation rate (ESR), and white blood cell, neutrophil, lymphocyte and platelet counts were recorded. The patients with ankylosing spondylitis were further divided according to their BASDAI scores into patients with inactive disease (BASDAI < 4) and patients with active disease (BASDAI ≥4). The correlations between the NLR, PLR and disease activity were analysed. Results: There was a statistically significant difference in the NLR and PLR between the active and inactive ankylosing spondylitis patients (2.31 ± 1.23 vs. 1.77 ± 0.73, p = 0.002), (142.04 ± 70.98 vs. 119.24 ± 32.49, p < 0.001, respectively). However, there was no significant difference in both the NLR and PLR between the healthy control group and ankylosing spondylitis patients (p > 0.05). In addition, the PLR was significantly higher in both the active and inactive groups compared to those in the healthy control group (142.04 ± 70.98 vs. 99.32 ± 33.97, p = 0.014), (119.24 ± 32.49 vs. 99.32 ± 33.97, p = 0.019). The BASDAI scores were positively correlated with the PLR (r = 0.219, p = 0.012) and the NLR, but they were not statistically significant with the later (r = 0.170, p = 0.051). Based on the ROC curve, the best NLR cut-off value for predicting severe disease activity in ankylosing spondylitis patients was 1.66, with a sensitivity of 61.8% and a specificity of 50.6%, whereas the best PLR cut-off value was 95.9, with a sensitivity of 70.9% and a specificity of 55.5%. Conclusion: The PLR may be used as a useful marker in the assessment and monitoring of disease activity in AS together with acute phase reactants such as the ESR.

Clinical Significance of NLR, PLR and MPV for Predicting Colorectal Adenomatous Polyp and Colorectal Cancer / 胃肠病学

Background: Many inflammatory markers have certain values in evaluating the prognosis of cancer patients, but studies on their diagnostic values for cancer and precancerous lesions are few. Aims: To explore the diagnostic significance of NLR, PLR and MPV for adenomatous polyp and colorectal cancer. Methods: Clinicopathological data of 198 patients with colorectal cancer (group A), 254 patients with adenomatous polyp (group B), 88 patients with non-adenomatous polyp (group C) diagnosed by endoscopic examination from September 2017 to July 2019 at Huludao Central Hospital were retrospectively analyzed, and 202 healthy subjects were served as controls (group D). WBC, NEU, LYM, PLT, MPV, NLR, PLR, CEA were compared among the four groups. ROC curve was used to evaluate the value of different parameters for diagnosing colorectal cancer and adenomatous polyp. Results: NLR, PLR, MPV had no relation with gender and age (P>0.05). WBC, NEU, PLT, NLR, PLR, CEA in group A were significantly increased when compared with group B, group C, group D (P<0.05), and LYM, MPV were significantly decreased (P<0.05). LYM, PLT in group B were significantly decreased when compared with group C (P<0.05), and NLR was significantly increased (P<0.05). WBC, NEU, NLR, CEA in group B were significantly increased when compared with group D (P<0.05), and PLT was significantly decreased (P<0.05). When the cut-off value was 1.93, 153.86, 10.55 fl, respectively, the AUC of NLR, PLR, MPV for diagnosing colorectal cancer were 0.877, 0.734, 0.704, respectively. The AUC of NLR combined with CEA for diagnosing colorectal cancer was 0.929, and the AUC of the combined NLR, PLR, MPV and CEA was 0.932. When the cut-off value was 1.62, the sensitivity of NLR for diagnosing adenomatous polyp was 68.1%, the specificity was 67.1%, AUC was 0.659, however, PLR and MPV had no significant value for diagnosing adenomatous polyp. Conclusions: NLR, PLR, MPV may have predicting value for detection of colorectal cancer, and combined with CEA can improve the efficacy. NLR may provide a new hematological screening method for detecting adenomatous polyp.

Correlation analysis of platelet-lymphocyte ratio with system involvement and disease activity in rheumatoid arthritis / 医学研究生学报

ObjectiveIt is very important to monitor the disease activity and complications of patients in the treatment of rheumatoid arthritis (RA). In this paper, we evaluated the level of platelet-lymphocyte ratio (PLR) of peripheral blood in patients with rheumatoid arthritis and discussed the relationship between PLR and the system involvement, laboratory indexes, and disease activity in patients with rheumatoid arthritis.MethodsFrom September 2013 to May 2017, 123 patients with rheumatoid arthritis who were first diagnosed in the General Hospital of Eastern Theater Command were analyzed retrospectively. 123 healthy persons(healthy control group) and 123 patients with other autoimmune diseases(disease control group) were matched according to the sex and age in a ratio of 1:1. According to the disease activity score 28 joints C-reactive protein (DAS28-CRP), RA patients were divided into the high activity group and the low activity group, and the PLR levels of high-activity and low-activity patients, healthy control group and disease control group were compared, respectively. To evaluate the relationship between system involvement and PLR level in RA patients; to analyze the correlation between PLR and DAS28-CRP and traditional inflammatory indexes by Spearman; to evaluate the application effect of receiver operating characteristic curve(ROC) in the diagnosis of RA and the differentiation of disease activity of RA patients.ResultsThe PLR level of RA patients was significantly higher than that of healthy people [133.63 (103.17, 140.99)] and disease control group [159.83(104.22, 203.55)], and the difference was statistically significant(P0.05]. There was a significant positive correlation between PLR and DAS28 CRP, C-reactive protein (CRP), ESR (r=0.433, 0.501, 0.592, P all <0.01）. The AUC of PLR in diagnosing RA and evaluating RA was 0.68 and 0.73 respectively. When cut off value was 134.47 and 147.61 respectively, sensitivity was 74.8% and 77.5%, specificity was 56.5% and 63.2%.ConclusionThe level of PLR of peripheral blood in patients with RA is increased, especially in patients with circulatory system involvement, infectious diseases or RF positive, and related to disease activity. PLR is expected to be an effective supplement for RA disease diagnosis and disease activity assessment and has potential application value.

Value of PLR in efficacy and prognosis of targeted therapy for NSCLC with EGFR mutation / 实用医学杂志

Objective To explore the value of PLR in peripheral blood in the efficacy and prognosis of targeted therapy for NSCLC with EGFR-mutated. Methods Ninety patients with EGFR-mutant of NSCLC were selected, and the PLR was calculated before targeted therapy. The PLR median was used as a cut-off point for grouping, and they were assigned to group A (low PLR group) and group B (high PLR group). All patients were treated with EGFR-TKIs. Relationship between PLR and clinicopathological features was analyzed. Objective efficacy, ORR, DCR, PFS and OS between the two groups were compared. Results Before EGFR-TKIs therapy, median PLR was 139, and there were 44 patients in group A, and 46 in group B. There were statistical differences regarding smoking, tumor location, histological differentiation, T staging, and clinical staging between group A and B (P <0.05). The rates of PR, ORR and DCR in group A were higher than those in group B, and the PD rate was lower than that in group B (P < 0.05). Log-rank test showed that median OS and median PFS in group A were longer than those in group B (P= 0.001). Conclusions PLR in peripheral blood has certain reference value for therapeutic effect and prognosis evaluation on NSCLC with EGFR-mutation. Low PLR of NSCLC patients with EGFR-mutation has higher efficacy and longer survival time after targeted therapy, and it is an independent and prognostic factor.

Objective To investigate the diagnostic value and clinical significance of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and lymphocyte-monocyte ratio (LMR) in children with bronchial asthma.Methods A total of 182cases newly diagnosed with asthma were divided into mild persistent group (68cases), moderate persistent group (63cases) and of severe persistent group (51cases), and 100ageand sex-matched pediatric healthy children at the same period were chosen as healthy control group.WBC, NEU, LYM, MON, EOS, PLT, IgE, NLR, PLR and LMR of all subjects enrolled in this research were retrospectively reviewed.Results There was no significant difference in age and sexuality between children with asthma and control group (P＞0.05), but WBC, EOS, NEU, MON, PLT and IgE were all significantly up-regulated, and LYM was down.NLR and PLR were significantly up-regulated in children with asthma, while LMR decreased significantly.The area under the curve (AUC) of ROC curve was 0.88and the cutoff value were 2.619for NLR in diagnosing asthmatic children.The diagnostic value of PLR was similar to that of NLR, the AUC of ROC value was 0.87, and the cutoff value was 111.1.The diagnostic value of LMR was only0.79, and the cutoff value was 5.093.In addition, there was a significant correlation between NLR and IgE or lung function indexes.PLR was also correlated with IgE, but only negatively correlated with lung function indexes such as FVC, FEV1and FEV1/FVC％.There was no significant correlation between LMR and all indexes.NLR and PLR were significantly decreased in children with severe asthma after treatment with budesonide, while LMR was significantly up-regulated.Conclusion There are abnormal changes in NLR, PLR and LMR in children with bronchial asthma, which can be used as an index for auxiliary diagnosis, disease assessment and therapeutic effect monitoring in children with bronchial asthma.

Increased Neutrophil-lymphocyte and Platelet-lymphocyte Ratios in Male Heroin Addicts: A Prospective Controlled Study

OBJECTIVE: The neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are markers that can determine the presence of systemic inflammatory response. In this study, we examined the NLR and PLR levels in patients with heroin dependence compared to healthy controls. METHODS: The study sample included 90 male patients with heroin dependence aged 18 to 45 years and 60 healthy subjects who had similar socio-demographic characteristics as the patient group. The diagnoses of heroin dependence and other Axis I psychiatric disorders in the patient and control groups were screened with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID-I). The extent of heroin addiction was assessed with the Addiction Severity Index (ASI). RESULTS: The mean NLR and PLR levels of patients with heroin dependence were significantly higher than the control subjects (p=0.031 and p < 0.001, respectively). Positive correlations were found between NLR, PLR and duration of the disorder. CONCLUSION: Our results indicate that inflammatory processes may play a role in the pathophysiology of heroin dependence.
