ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
