Construction of postoperative prognosis model for patients with colorectal cancer / 国际肿瘤学杂志

Objective:To screen the factors influencing overall survival (OS) of patients undergoing radical resection for colorectal cancer (CRC) and to construct a prognostic model for OS of patients after CRC.Methods:The clinical data of 350 patients with stage Ⅰ-Ⅳ CRC who underwent radical resection in the People's Hospital of Wuhan University from March 2017 to December 2019 were collected retrospectively. Patients were divided into subgroups 0 ( n=70), 1 ( n=172), and 2 ( n=108) according to different preoperative systemic inflammation score (SIS). The relationship between different SIS, neutrophil to lymphocyte ratio (NLR), lymphocyte to monocyte ratio (LMR), systemic immune inflammation index (SII) and prognosis of CRC patients undergoing radical surgical resection were analyzed, and Cox regression models were used to perform univariate and multifactorial analyses of factors affecting patient prognosis, and column line graph models were constructed based on the results of multifactorial analyses. Results:By the deadline of follow-up, 80 of 350 CRC patients died, and the 5-year OS rate was 77.14%. The 5-year survival rates of patients in SIS group 0, group 1 and group 2 were 95.71%, 79.65% and 61.11% respectively, with a statistically significant difference ( χ2=30.19, P<0.001). Statistically significant differences in age ( χ2=19.40, P<0.001), tumor site ( χ2=8.18, P=0.017), T stage ( χ2=10.01, P=0.007), TNM stage ( χ2=14.80, P=0.001), tumor diameter ( χ2=13.91, P=0.001) and carcino-embryonic antigen (CEA) level ( χ2=10.12, P=0.006) among patients in SIS group 0, group 1 and group 2. The 5-year OS rates of patients in the low NLR and high NLR groups were 82.67% and 56.16% respectively, with a statistically significant difference ( χ2=24.96, P<0.001) ; the 5-year OS rates of patients in the low LMR and high LMR groups were 66.85% and 88.17% respectively, with a statistically significant difference ( χ2=22.45, P<0.001) ; the 5-year OS rates of patients in the low SII and high SII groups were 86.14% and 69.02% respectively, with a statistically significant difference ( χ2=14.76, P<0.001). Univariate analysis showed that age ( HR=2.58, 95% CI: 1.54-4.32, P<0.001), T stage ( HR=2.41, 95% CI: 1.24-4.68, P=0.009), N stage ( HR=3.03, 95% CI: 1.85-4.94, P<0.001), TNM stage ( HR=3.61, 95% CI: 2.15-6.04, P<0.001), nerve invasion ( HR=1.97, 95% CI: 1.27-3.08, P=0.002), vascular invasion ( HR=2.31, 95% CI: 1.49-3.59, P<0.001), preoperative SIS 1 score ( HR=5.09, 95% CI: 1.57-16.56, P=0.007), SIS 2 score ( HR=11.05, 95% CI: 3.42-35.65, P<0.001), NLR ( HR=2.97, 95% CI: 1.90-4.64, P<0.001), LMR ( HR=0.31, 95% CI: 0.19-0.52, P<0.001), and SII ( HR=2.50, 95% CI: 1.54-4.06, P<0.001) were all independent influence factors affecting the postoperative prognosis of CRC patients undergoing radical surgical resection; multivariate analysis showed that age >60 years ( HR=2.27, 95% CI: 1.31-3.91, P=0.003), TNM stage Ⅲ-Ⅳ ( HR=7.08, 95% CI: 1.89-26.59, P=0.004), and preoperative SIS 2 score ( HR=4.02, 95% CI: 1.09-14.83, P=0.037) were all independent risk factors affecting the postoperative prognosis of CRC patients undergoing radical surgical resection. The nomogram model built based on the screened variables has high prediction accuracy: the C-index of the nomogram was 0.75. Conclusion:Age>60 years old, TNM stage Ⅲ-Ⅳ, SIS 2 score are all independent risk factors for postoperative prognosis of colorectal cancer. The nomograph model constructed by this method has high prediction accuracy.

O Índice de Inflamação Imune Sistêmica é um Novo Marcador na Previsão da Presença e Gravidade aa Ectasia Coronariana Isolada / Systemic Immune Inflammation Index is a Novel Marker in Predicting the Presence and Severity of Isolated Coronary Artery Ectasia

Resumo Fundamento A patologia subjacente da ectasia da artéria coronária (EC) isolada não foi totalmente elucidada. Objetivo Nosso objetivo foi examinar a relação entre o índice de inflamação imune sistêmica (Sıı), que corresponde à multiplicação da razão neutrófilos-linfócitos (RNL) e as contagens de plaquetas, e EC isolada. Método A população do estudo retrospectivo incluiu 200 pacientes com EC isolada, 200 consecutivos com doença arterial coronariana obstrutiva e 200 consecutivos com angiografia coronária normal. Um valor de p bicaudal <0,05 foi considerado significativo. Resultados Sıı, RNL, razão plaqueta-linfócito (RPL) e razão monócito-colesterol de lipoproteína de alta densidade (MHR) foram significativamente maiores no grupo EC em comparação com os outros grupos (todos p<0,001). Na análise multivariada, Sıı (p<0,001, OR = 1,005, IC 95% =1,004-1,005) foi considerado um preditor independente de EC isolada. Na análise da curva Receiver Operating Characteristic (ROC), Sıı teve uma área sob a curva maior em comparação com RNL, RPL e MHR. O valor de Sıı >517,35 tem 79% de sensibilidade, 76% de especificidade para a predição do EC [AUC: 0,832, (p<0,001)]. Sıı teve correlação significativa com o número de artérias coronárias ectásicas e classificação de Markis (r: 0,214 p=0,002; r:-0,195, p=0,006, respectivamente). Conclusão Até onde sabemos, este é o primeiro estudo em que Sıı foi significativamente associado à presença isolada de EC e gravidade anatômica.

Abstract Background The underlying pathology of isolated coronary artery ectasia (CE) has not been fully elucidated. Objective We aimed to examine the relationship between the systemic immune inflammation index (Sıı), which corresponds to the multiplying of the neutrophil-to-lymphocyte ratio (NLR) and the platelet counts, and isolated CE. Method The retrospective study population included 200 patients with isolated CE, 200 consecutive with obstructive coronary artery disease, and 200 consecutive with a normal coronary artery angiogram. A 2-sided p-value of <0.05 was considered significant. Results Sıı, NLR, platelet-to-lymphocyte ratio (PLR), and monocyte-to-high density lipoprotein cholesterol ratio (MHR) were significantly higher in the CE group compared with the other groups (all p<0.001). In multivariate analysis, Sıı (p<0.001, OR = 1.005, 95% CI =1.004-1.005) was found to be an independent predictor of isolated CE. In Receiver Operating Characteristic curve analysis, Sıı had a higher Area Under the Curve than NLR, PLR, and MHR. Sıı value of >517.35 has 79% sensitivity, 76% specificity for the prediction of the CE [AUC: 0.832, (p<0.001)]. Sıı had a significant correlation with the number of ectatic coronary arteries and Markis classification (r:0.214 p=0.002; r:-0.195, p=0.006, respectively). Conclusion To the best of our knowledge, this is the first study that Sıı was significantly associated with isolated CE presence and anatomical severity.

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.

Systemic immune inflammation index in patients with recurrent aphthous stomatitis / Índice de inflamação imune sistêmica em pacientes com estomatite aftosa recorrente

Abstract Objectives: Recurrent Aphthous Stomatitis (RAS) a chronic idiopathic oral mucosal disease. But yet the etiology and pathogenesis of RAS are not exactly known, it is thought that inflammation play an important role in the pathogenesis. The aim of this study is to demonstrate the role of systemic inflammation among the possible etiological factors of RAS and to find the possible diagnostic correlation between Systemic Immune Inflammation Index (SII). Methods: Patients who were consulted the otolaryngology outpatient clinic and diagnosed with RAS between 2019-2021 were retrospectively analyzed. Neutrophil/Lymphocyte Ratio (NLR), Platelet/Lymphocyte Ratio (PLR) and SII values were calculated based on the results of complete blood count. Demographic and hematological parameters between control and RAS groups were compared. The statistical significance level was considered as <0.05. Results: There was no statistically significant difference between the control and RAS groups in terms of sex and age distributions (p = 0.566 and p = 0.173, respectively). SII, NLR and PLR values were significantly higher in the RAS group compared to the controls (p < 0.001, p < 0.001 and p = 0.001, respectively). A very strong correlation between SII and NLR, moderately strong correlation between SII and PLR and moderate correlation between NLR and PLR values were detected (respectively ρ: 0.813, 0.719, 0.532; p-values <0.001). Conclusion: SII, NLR and PLR has significantly higher levels in the RAS group compared to the control group, that it supports the role of systemic inflammation in the etiopathogenesis of RAS. In addition, the results show that SII is a valuable marker for inflammation. Level of evidence: 4. HIGHLIGHTS RAS is a chronic, idiopathic, ulcerative oral mucosal disease. SII is a new and inexpensive biomarker that can easily be calculated using the platelet, neutrophil, and lymphocyte count. SII may be a valuable marker to demonstrate the role of systemic inflammation in RAS etiopathogenesis. Vascular, thrombotic, and inflammatory processes are thought to have a role in RAS activation.

Resumo Objetivo: A estomatite aftosa recorrente (EAR) é uma doença crônica idiopática da mucosa oral. Embora sua etiologia e patogênese não sejam totalmente conhecidas, acredita-se que a inflamação possa desempenhar um papel importante. O objetivo deste estudo é demonstrar o papel da inflamação sistêmica entre os possíveis fatores etiológicos da estomatite aftosa recorrente e encontrar uma possível correlação diagnóstica com o índice de inflamação imunológica sistêmica, SII. Método: Foram analisados retrospectivamente pacientes avaliados no ambulatório de otorrinolaringologia e diagnosticados com estomatite aftosa recorrente entre 2019-2021. A relação neutrófilos/linfócitos, a relação plaquetas/linfócitos e os valores de SII foram calculados com base nos resultados do hemograma completo. Parâmetros demográficos e hematológicos dos grupos controle e de pacientes foram comparados. O nível de significância estatística foi considerado como <0,05. Resultados: Não houve diferença estatisticamente significante entre os grupos controle e com estomatite aftosa recorrente quanto à distribuição por sexo e idade (p = 0,566 e p = 0,173, respectivamente). Os valores de SII, a relação neutrófilos/linfócitos e a relação plaquetas/linfócitos foram significantemente maiores no grupo de pacientes em relação aos controles (p <0,001, p <0,001 e p = 0,001, respectivamente). Foi detectada uma correlação muito forte entre SII e relação neutrófilos/linfócitos, uma correlação moderadamente forte entre SII e relação plaquetas/linfócitos e uma correlação moderada entre valores da relação neutrófilos/linfócitos e relação plaquetas /linfócitos (ρ: 0,813, 0,719, 0,532 respectivamente; p-valores <0,001). Conclusão: SII, relação neutrófilos/linfócitos e relação plaquetas/linfócitos apresentam níveis significantemente maiores no grupo com estomatite aftosa recorrente quando comparados ao grupo controle, o que corrobora o papel da inflamação sistêmica na sua etiopatogênese. Além disso, os resultados mostram que o SII é um marcador inflamatório valioso. Nível de evidência: 4. HIGHLIGHTS A estomatite aftosa recorrente é uma doença ulcerativa crônica idiopática da mucosa oral. O SII (do inglês Systemic Immune Inflammation Index) é um biomarcador novo e de baixo custo que pode ser facilmente calculado que usa a contagem de plaquetas, neutrófilos e linfócitos. O SII pode ser um marcador valioso para demonstrar o papel da inflamação sistêmica na etiopatogênese da estomatite aftosa recorrente. Acredita-se que processos vasculares, trombóticos e inflamatórios tenham um papel na ativação da estomatite aftosa recorrente.

Prognostic value of pre-operation systemic inflammation response index in decompressive craniectomy for massive cerebral infarction caused by middle cerebral artery embolization / 中国综合临床

Objective:To explore the correlation between systemic inflammatory response index (SIRI) and clinical outcome of patients with massive cerebral infarction (MCI) after craniotomy and decompression.Methods:The clinical data of 50 MCI patients who were treated in the Affiliated Hospital of Qingdao University from January 2016 to December 2020 and underwent craniotomy and decompression were retrospectively analyzed. The measurement data of normal distribution were expressed as xˉ± s, and the measurement data of non normal distribution were expressed as M( Q1, Q3). T-test or rank sum test was used for comparison between the two groups. Multivariate Logistic regression was used to analyze the relationship between SIRI and prognosis of MCI patients and establish a prediction model. The predictive value and optimal cutoff value of SIRI were analyzed by receiver operating characteristic curve (ROC). Results:Among the 50 MCI patients who underwent craniotomy and decompression, 12 (24%, 12/50) had a good prognosis; In the poor prognosis group, 38 cases (76%, 12/50), of which 9 cases (18%, 9/50) died during hospitalization. The age of patients in the good prognosis group and the poor prognosis group ((54±11) years and (63±9) years; t=2.72, P=0.015), body mass index (BMI): ((23.91±2.64) kg/m 2 and (26.72±3.28) kg/m 2, t=3.01, P=0.006)), neutrophil count (7.08 (5.12, 7.38))×10 9/L and 10.59 (8.91,14.64)×10 9/L, Z=5.72, P<0.001), white blood cell count ((9.09±2.80)×10 9/L and (13.20±3.49) ×10 9/L; t=4.16, P<0.001), SIRI (2.49(1.78, 4.75) and 8.34(5.17, 13.61); Z=3.84, P<0.001), Glasgow Coma Score (12(9,14) and 8(6,10); Z=3.36, P=0.002) and lymphocyte count (1.58(0.91, 1.91)×10 9/L and 0.77(0.59,1.02) ×10 9/L; Z=3.30, P=0.001).The difference between the two groups was statistically significant. The prognosis of patients with dominant hemisphere infarction was worse than that of patients with non-dominant hemisphere infarction (22 cases (91.67%, 22/24) vs. 16 cases (61.54%, 16/26); χ 2=6.21, P=0.013). The ICU stay in the good prognosis group was significantly shorter than that in the poor prognosis group (2 (1, 5) days vs. 8 (3, 19) days; Z=2.78, P=0.005). Multivariate Logistic regression analysis showed that SIRI and GCS were correlated with clinical prognosis: SIRI ( OR: 2.378; 95% CI: 1.131-5.003; P=0.022); GCS at admission ( OR: 0.548; 95% CI: 0.307-0.980; P=0.043). The ROC curve analysis of SIRI prediction of poor prognosis: Area under the curve (AUC): 0.871, (95% CI: 0.765-0.976, P<0.001), sensitivity was 78.9%, specificity was 88.3%, and the optimal cut-off value was 4.96. The sensitivity, specificity and AUC of GCS for predicting poor prognosis after MCI craniotomy decompression were 89.5%, 58.3% and 0.791 (95% CI: 0.638~0.943, P=0.003), and the best truncation value was 11.5. Conclusion:SIRI was an effective predictor of clinical outcome for MCI patients underwent Craniotomy for decompression, and SIRI value greater than 4.96 indicates adverse clinical outcome.

Comparison of predictive efficacy of two preoperative inflammatory scores in patients with gallbladder cancer / 国际外科学杂志

Objective:To investigate and compare the influence of systemic inflammation score(SIS) and modified glasgow prognostic score(mGPS) on patients undergoing radical surgery for gallbladder cancer.Methods:A cohort study was used to collect the clinical data of total 50 patients with gallbladder cancer who underwent radical surgery in Zhongda Hospital Affiliated to Southeast University from March 2010 to March 2020. Survival analysis was utilized to assess the impact of SIS and mGPS for prognosis.The predictive accuracy of each score was compared by means of subgroup analysis and time dependent receiver operating characteristics analysis.Measurement data with normal distribution were expressed as mean±standard deviation( ± s), and t test was used for comparison between groups. Count data were expressed as cases and percentages (%), and chi-square test was used for comparison between groups. Results:The 1-, 2-and 3-year survival rate of 50 gallbladder cancer patients undergoing radical surgery were 76%, 55%, 37.6%. Cox multivariate analysis showed SIS score ( HR=2.072, P=0.014) was independent prognostic risk factor; Time dependent ROC curve analysis found that the area under the SIS curve was significantly greater than the mGPS at postoperative 1 year (0.748 vs 0.603, P=0.024); Subgroup analysis found in advanced patients, SIS score was statistically significant compared with mGPS ( P=0.03). Conclusions:SIS is superior to mGPS for predicting OS in patients with gallbladder cancer who underwent radical surgery, and SIS is an independent risk factors for prognosis of patients with gallbladder cancer.

Microalbuminuria and High-Sensitivity C-Reactive Protein as Potential Biomarkers of Systemic Inflammation in Patients with Chronic Obstructive Pulmonary Disease

Abstract There isn't yet a clear definition for systemic inflammation in COPD (chronic obstructive pulmonary disease), but its recognition has been based on studies that show an increase in the plasma concentration of various inflammatory markers, such as the c-reactive protein (CRP), and in recent years, also the microalbuminuria has been suggested. The purposes of this work were to determine the microalbuminuria and CRP as potential biomarkers of systemic inflammation. We enrolled patients with stable COPD and non-COPD smokers diagnosed through spirometry; older than 40 years without AHT (arterial hypertension) or diabetes type I or II, between October 2017 and March 2019. In both groups, a venous blood sample was collected to determine high-sensitivity CRP and 3 urine samples were taken to determine microalbuminuria, calculating the mean value. At least two out of three determinations between 30 and 300 mg/g of urine creatinine were considered to be significant albuminuria. The high-sensitivity CRP was considered positive with a value ≥ 5 mg/L. Of the 47 analyzed patients, a mean albuminuria of 13.91 ± 5.04 was obtained in the COPD group, in comparison with 2.50 ± 0.36 in the control group. Also, the high-sensitivity CRP mean values were compared, showing 5.06 ± 2.24 in COPD patients and 2.46 ± 0.51 in the control group. Both variables showed non-statistically significant differences between the study groups (p = 0.058 for mean albuminuria and p = 0.330 for high-sensitivity CRP).

Effect of Exercise on Chronic Obstructive Pulmonary Disease Systemic Inflammation and Skeletal Muscle Dysfunction: A Systematic Review / 中国康复理论与实践

Objective To systematically review the effects of exercise on systemic inflammation of chronic obstructive pulmonary disease (COPD) and skeletal muscle dysfunction. Methods The literature about the effect of exercise on COPD systemic inflammation and skeletal muscle dysfunction were retrieved from PubMed, Web of Science, CNKI, VIP and Wanfang data, until June, 2021, supplemented by reference review and manual retrieval. Results A total of 192 literatures were retrieved and eight were included, involving 245 subjects. The comprehensive results showed that exercise could decrease the level of pro-inflammatory factors and increase the level of anti-inflammatory factors. Exercise can improve the motor ability and skeletal muscle structure of patients with COPD. Exercise can improve systemic inflammation of COPD, which is related to the mode, intensity and duration of exercise. Exercise may affect ubiquitin-protease, insulin-like growth factors -1/phosphatidylinositol 3 kinase/Akt and other pathways by regulating the inflammatory response, and improve skeletal muscle dysfunction. Conclusion Exercise has certain effect on reducing systemic inflammation and improving skeletal muscle dysfunction.

Level of C-reactive Protein in Obese and Overweight Individuals at Indira Gandhi Institute of Medical Sciences: A Tertiary Care Center of Bihar

Introduction: Human adipose tissue releases interleukin-6 which is a pro-inflammatory cytokine that causes low-grade systemicinflammation. Acute-phase C-reactive protein (CRP) is a sensitive marker for systemic inflammation. Low-grade systemicinflammation in overweight and obese can be measured by serum CRP level.Objective: The objective of this study was to find out the prevalence of raised serum CRP level among the obese and overweightperson.Materials and Methods: Overweight and obese persons were screened for raised CRP (≥3.0 mg/L) after excluding comorbidity.Results: The prevalence of raised CRP among obese and overweight is 23%, the female has higher prevalence of 25.45% ascompared to male 20%. The prevalence among overweight and obese participants is 18.88% and 60%, respectively.Conclusions: The finding suggest a higher prevalence of low-grade systemic inflammation in obese as compared to anoverweight person.

Prognostic significance of inflammatory markers in patients with rare kidney cancers

Background: Although clear cell renal cell carcinoma (ccRCC) is the most common histological variety of malignant renal tumor, histological variants are often encountered in clinical practice which behaves differently. Paucity of such tumors makes them a subject of interest worldwide. As per European Association of Urology, since ccRCC is a non-designation, they included all non-clear cell RCC under one nomenclature as rare kidney cancer (RKC). The objective of our study is to determine influence of inflammatory markers on the prognosis of RKC.Methods: Data from cancer registry was retrieved and all rare kidney cancer patient’s data were analysed particularly the markers of inflammation like neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), systemic inflammatory immune index (SIII) and C reactive protein (CRP) to albumin ratio and their probable influence on cancer free survival (CFS), progression free survival (PFS) and overall survival (OS).Results: Data of 33 cases of rare kidney cancers were included in this study. The follow up duration ranges from 6.8 months to 38.6 months. In the univariate analysis, NLR had a significant influence on CFS, PFS and OS (cutoff value-3.2, 95% confidence interval [CI], CFS: p<0.05; PFS: p=0.05; OS: p<0.05), PLR in respect to CFS (cutoff value-67.5, 95% CI, p<0.05) and SIII had a significant impact on CFS and OS (cutoff value-8.67, 95% CI, 11.10-19.57, CFS: p<0.05; OS: p<0.05).Conclusions: Inflammation markers such as NLR, PLR, SII Index and CRP or albumin ratio could be independent predictors of clinical outcome and prognostics factors in rare kidney cancers. However, this needs to be validated by multicentre randomised studies.

Anti-inflammatory Effect of a Goji Berry Extract (Lycium barbarum) in Rats Subjected to Inflammation by Lipopolysaccharides (LPS)

Abstract The present study aimed to evaluate the anti-inflammatory potential of a Lycium barbarum (L. barbarum) fruit extract in Wistar rats submitted to a palatable diet presenting systemic inflammation induced by lipopolysaccharides (LPS). Forty-two Wistar female rats (Rattus Novergicus) were used with 60 days old. The animals were feed for 60 days and divided in six groups (n=7): standard diet+water; standard diet+L. barbarum; palatable diet+water; palatable diet+L. barbarum; standard diet+water+LPS; standard diet+L. barbarum+LPS. A significant difference was shown between the analyzed groups concerning C-reactive protein, with the standard diet+water+LPS group presenting the highest inflammatory response in comparison to the other groups. Decreased inflammatory response was observed in the group administered a palatable diet along with the fruit extract when compared to the group that received only a palatable diet. Significant decrease in glutamic-oxaloacetic transaminase activity was observed in the standard diet+L. barbarum+LPS group compared to the standard diet+water group, as well as in the palatable diet+L. barbarum group compared to the palatable diet+water group. A significant increase in creatinine in the standard diet+water+LPS group was observed in according to the L. barbarum administration groups. The gene expression of the inflammatory markers genes in the liver showed a significant increase in TNF-α and IL-6 genes in the group treated with standard diet+L. barbarum+LPS when compared to the standard diet+LPS group. Thus, the administered L. barbarum extract displays the potential to reduce inflammatory responses induced by LPS and a palatable diet.

Effects of progesterone and estradiol on the inflammatory and apoptotic markers of ovariectomized rats challenged with acute septic systemic inflammation

The inflammatory responses during septic inflammation were affected by the differential role of progesterone and estrogen that demonstrated pro-inflammatory and anti-inflammatory roles. This study was designed to evaluate the differential effects of estradiol and progesterone supplementation on the inflammatory and apoptotic responses in an ovariectomized (OVX) rat model of acute systemic septic inflammation (SSI). This study was conducted on 60 female Wistar rats. 40 mg/kg estradiol and 5 mg/kg progesterone were given subcutaneous (s.c.) to OVX rats, after the induction of SSI through caecum puncture with a 21-gauge needle. Serum levels of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), Alanine transaminase (ALT), estradiol, and progesterone were evaluated; additionally, Inducible nitric oxide synthase (iNOS), Cyclooxygenase (COX)-II, and caspase-3 were evacuated in liver tissue homogenates using the Enzyme-linked immunosorbent assay (ELISA) method. In OVX rats challenged with SSI, serum TNF-α, CRP, and ALT levels were significantly increased associated with a decrease in serum estradiol levels. They also showed overexpression of iNOS and increased the activity of COX-II and caspase-3 in the liver compared to non-OVX rats subjected to SSI. Supplementation with estradiol significantly decreases all serum and liver tissue markers of inflammation and decreased apoptosis. In contrast, in OVX rats supplemented with progesterone, SSI resulted in a significant increase in the studied markers. In conclusion, the supplementation of estradiol in OVX rats challenged with SSI significantly attenuated the systemic and liver inflammatory and apoptotic markers. Meanwhile, the supplementation with progesterone exacerbates the effects of the inflammatory markers and increases the tendency of apoptosis in the liver tissue.

Cell-free chromatin: A newly described mediator of systemic inflammation

Recent research has shown that cell-free chromatin (cfCh) particles that are released from the billions of cells that die in thebody everyday can enter into healthy cells, integrate into their genomes and induce dsDNA breaks and apoptotic responses.Genomic integration of cfCh activates NFjB suggesting a novel mechanism of induction of systemic inflammation. SinceDNA damage and inflammation are underlying pathologies in multiple devastating acute and chronic disease conditions,the discovery of agents that can inactivate cfCh may provide therapeutic possibilities.

18F-fluorodeoxyglucose positron emission tomography-based evaluation of systemic and vascular inflammation and assessment of the effect of systemic treatment on inflammation in patients with moderate-to-severe psoriasis: A randomized placebo-controlled pilot study

Background: Psoriasis is a systemic inflammatory disorder associated with an increased risk of cardiovascular disease. Objective: To evaluate the utility of [[18]F]-fluorodeoxyglucose positron emission tomography/computed tomography in identifying vascular and systemic inflammation in psoriasis patients with moderate-to-severe disease and to analyze its usefulness in assessing the effect of systemic treatment. Methods: This was a randomized, double-blind pilot study conducted in a tertiary care center. Baseline standardized uptake value score was estimated by18F-fluorodeoxyglucose positron emission tomography/computed tomography in patients with moderate-to-severe psoriasis and compared with historical controls. Patients were then randomized using computer-generated randomization list into methotrexate or placebo (with or without pioglitazone) groups.18F-fluorodeoxyglucose positron emission tomography/computed tomography was repeated at 12 weeks and composite standardized uptake value score determined. The correlation between Psoriasis Activity and Severity Index and SUVmax was assessed. Results: A total of 16 patients were randomized to different treatment groups. Significant increase in mean SUVmax was observed in the ascending aorta in psoriasis patients as compared to historical controls (2.03 ± 0.53 vs 1.51 ± 0.36, P < 0.03). There was no difference in composite standardized uptake value score after 12 weeks of treatment in any of the treatment groups (P = 0.82), although an improvement in Psoriasis Activity and Severity Index score in the methotrexate arm was observed. No correlation was found between mean SUVmax and Psoriasis Activity and Severity Index scores in various aortic segments (r = 0.3–0.7). Limitations: Small sample size, short follow-up, historical controls, exclusion of patients with comorbid conditions and lack of surrogate markers of systemic inflammation. Conclusion: 18F-fluorodeoxyglucose positron emission tomography imaging showed higher vascular inflammation in ascending aorta of psoriasis patients as compared to historical controls. Systemic treatment with methotrexate and pioglitazone did not influence the vascular inflammation in the short term.

Quercetin reduces the transcriptional activity of NF-kB in stable coronary artery disease

Objective The aim of this study was to determine the effect of quercetin on the indicators of chronic systemic inflammation (CSI) in stable coronary artery disease (CAD). Methods This study included 85 patients with CAD, stable angina pectoris, functional class (FC) II, and heart failure (НF) 0-І. Each patient was prescribed beta-blockers, statins, and aspirin. In addition, a total of 30 patients, forming the study group received quercetin at a daily dose of 120 mg for two months, while the remaining 55 patients made up the control group. The levels of cytokines, such as tumor necrosis factor (TNF-α), interleukin-1β (IL-1β), and interleukin-10 (IL-10) in serum and the expression of the inhibitor of kappa B α (IkBα) gene in blood mononuclear cells, were determined. Results The increased levels of IL-1β and TNF-α, as well as a moderate increase in IL-10 levels, were detected in the serum of patients with CAD. The expression of the IkBα gene (2–δСt) did not differ significantly between the groups. Under the influence of quercetin, levels of IL-1β and TNF-α were reduced and IL-10 levels tended to decrease. In contrast, the serum levels of these cytokines did not change significantly in the control group. The administration of quercetin decreased the expression of the IkBα gene (0.0092 ± 0.0033 against 0.0261 ± 0.0166, р = 0.003; 2–δδСt, 2.82 ± 1.39 times) in contrast to the control group. Conclusion Quercetin showed anti-inflammatory properties in patients with CAD, indicating a decrease in transcriptional activity of the nuclear factor of transcription kappa B (NF-kB).

Effect of systemic inflammation response index on clinical prognosis of patients with glioma and its relationship with IDH1 mutation / 实用肿瘤学杂志

Objective The objective of this study was to investigate the effect of systemic inflammation response index(SI-RI)on clinical prognosis of patients with glioma and its relationship with dehydrogenase 1(IDH1)mutation.Methods Eighty patients with glioma who underwent surgery in the department of Neurosurgery were collected from August 2006 to November 2015.The best clinical cutoff value for SIRI was determined using operating characteristic curve(ROC)and grouped accordingly.The Kaplan-Meier and log-rank methods were used to analyze the postoperative survival of the two groups of patients.The independent clinical prognos-tic factors were evaluated by Cox′s proportional hazards regression model.The IDH1 mutation was detected by immunohistochemistry and DNA sequencing.Results SIRI was an independent prognostic factor of glioma,and the best clinical cutoff value was 0.67 × 109/L.The median progress free survival(PFS)and overall survival(OS)of patients with low SIRI group were 46.90 months and 57.90 months,and the median PFS and OS of patients with high SIRI group were 31.78 months and 47.22 months,respectively.There was significant difference between the two groups in the median survival time of PFS and OS by log-rank method(P<0.05).Univa-riate and multivariate analysis showed that age,gender,type of surgery,WHO stage,SIRI and IDH1 mutation were the independent prognostic factors in neurostein stromal tumors.Patients with low-grade SIRI and glioma with IDH1 mutation have a better prognosis than other conditions.Conclusion SIRI is an independent prognostic factor of glioma.It is simple,convenient and reproducible,and may be used to predict the prognosis of patients with glioma.

Pretreatment systemic inflammation response index as an independent prognostic indicator for prostate cancer patients treated with maximal androgen blockade / 中华泌尿外科杂志

Objective To investigate the efficacy of pretreatment systemic inflammation response index (SIRI) in predicting the prognostic of prostate cancer (PCa) patients treated with maximal androgen blockade (MAB).Methods The data of 351 PCa patients who had undergone MAB as first-line therapy between January 2010 and June 2015,were retrospectively analyzed.The age of patients in our cohort ranged from 51 to 89 years old,mean 76 years old.The median value of PSA was 91.60ng/ml,ranging 0.11-1 000.00 ng/ml.39 cases had a Gleason score of 6,47 cases had a score of 3 + 4,89 cases had a score of 4 +3,107 cases had a score of 8,and 69 cases had a score of 9-10.158 cases had bone metastasis.Patients were categorized in two groups using a cut-off point of 1.2 as calculated by the receiver-operating curve analysis.Correlations between SIRI and clinical characteristics were analyzed.Meanwhile,univariate and multivariate cox regression analyses were performed to determine the associations of SIRI with progression-free survival (PFS),cancer-specific survival (CSS) and overall survival (OS).Results The median follow-up duration was 43.0 months,ranging 9-75 months.The disease progression occurred in 162 patients,91 patients died,including 75 who died because of PCa at the end of the last follow-up.The differences of age,Gleason score and incidence of metastasis between low SIRI group (＜ 1.2) and high SIRI group (≥1.2) were not significant (P ＞0.05).But the patients in high SIRI group had higher PSA (P =0.046).Multivariate analyses identified SIRI,Gleason score and metastasis as independent prognostic factors for PFS,CSS and OS.Conclusions Pretreatment SIRI ≥ 1.2 was an independent predictor for poor prognosis in PCa patients treated with MAB.

Relación entre síndrome metabólico e índice neutrófilo/linfocito / Relation between metabolic syndrome and neutrophil to lymphocyte ratio

Resumen ANTECEDENTES: el síndrome metabòlico agrupa factores de riesgo de diabetes mellitus 2 y enfermedad cardiovascular: obesidad central, hiperglucemia, hipertensión arterial, hipertrigliceridemia y colesterol de alta densidad (C-HDL) reducido. La obesidad y el síndrome metabòlico son afecciones en las que sobreviene inflamación subclínica crónica, factor de riesgo independiente de enfermedad cardiovascular y aterosclerosis. El índice neutrófilo/linfocito (INL) ha surgido como un marcador pronóstico asociado con un estado proinflamatorio que refleja el equilibrio entre la respuesta inmunitaria innata y adaptativa. OBJETIVO: definir la relación entre el índice neutrófilo/linfocito (INL) elevado y el síndrome metabólico en trabajadores activos adscritos al Hospital Central Norte de PEMEX. Los objetivos secundarios fueron establecer la relación entre el índice neutrófilo/linfocito y los componentes del síndrome metabólico individualmente. MATERIAL Y MÉTODO: estudio retrospectivo, transversal y observacional en el que se evaluaron trabajadores activos de PEMEX de 18 a 65 años de edad y se clasificaron en dos grupos de acuerdo con la existencia o ausencia de síndrome metabólico y se calculó el índice neutrófilo/linfocito de cada uno. RESULTADOS: se incluyeron 334 pacientes, 155 (46%) no cumplieron criterios para síndrome metabólico y 179 (54%) sí. De los pacientes en el cuartil más alto de índice neutrófilo/linfocito (>2.12) 57 correspondieron al grupo con síndrome metabólico (p=0.000). El coeficiente de correlación biserial puntual entre índice neutrófilo/ linfocito y síndrome metabólico fue de 0.235 (p=0.000); 69 de los 235 pacientes con obesidad central estaban en el cuartil más alto de índice neutrófilo/linfocito (p=0.001). CONCLUSIONES: los hallazgos sugieren que existe una relación significativa entre la elevación del índice neutrófilo/linfocito (>2.12) y la existencia de síndrome metabólico y obesidad central.

Abstract BACKGROUND: Metabolic syndrome is a cluster of factors that increases the risk for developing type 2 diabetes mellitus and cardiovascular disease (CVD): central obesity, elevated fasting plasma glucose, arterial hypertension, raised triglycerides and reduced high-density lipoprotein cholesterol (HDL-C). Metabolic syndrome and obesity are entities in which chronic subclinical inflammation develops, an independent risk factor for atherosclerosis and CVD. Neutrophil to lymphocyte ratio (NLR) has emerged as a prognostic marker associated to a proinflammatory state, which reflects the balance between innate and adaptive immune responses. OBJECTIVE: To define the relation between an elevated NLR and the presence of metabolic syndrome in active employees that attend to PEMEX North Central Hospital. Secondary objectives were to establish the relation between NLR and each component of metabolic syndrome individually. MATERIAL AND METHOD: A retrospective, cross-sectional and observational stud was done including employees 18-65 years old and classified them into 2 groups according to metabolic syndrome criteria, NLR was calculated for every patient. RESULTS: Of 334 evaluated patients, 155 (46%) didn't meet the metabolic syndrome criteria, and 179 (54%) did. Fifty-seven patients in the highest quartile of NLR (>2.12) corresponded to the metabolic syndrome group (p=0.000). Point biserial correlation coefficient between NLR and metabolic syndrome was 0.235 (p=0.000). Sixty-nine of the 235 patients with central obesity were at the highest quartile of NLR (p=0.001). CONCLUSION: These findings suggest that there is a statistically significant relation between elevated NLR (>2.12) and presence of metabolic syndrome and central obesity.
