Systemic Immune Index Research Articles

Evaluation of pseudoexfoliation syndrome patients with systemic immune indexes.

The aim of this study was to investigate the level of peripheral blood systemic immune indexes in pseudoexfoliation syndrome (PXS) patients and to compare the results with healthy controls. This study included 143 healthy controls (group 1) and 100 patients (group 2). Peripheral blood samples were collected from all participants. Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), monocyte to lymphocyte ratio (MLR), systemic immune inflammation index (SIII), systemic inflammation response index (SIRI), systemic inflammation modulation index (SIMI) and aggregate systemic inflammation index (AISI) were calculated. According to complete blood count, leukocyte, monocyte and platelet counts showed a statistically significant difference between the two groups (p < 0.001 for all). Systemic immune indexes (NLR, PLR, SIII, SIRI, SIMI and AISI) in group 2 were statistically significantly higher compared to group 1 (PLR for p = 0.011, others p < 0.001). In conclusion, systemic immune indexes (NLR, MLR, PLR, SIII, SIRI, AISI and SIMI) were elevated in PXS patients compared to healthy controls. These indexes may serve as an easy, simple and cost-effective tool to assess the degree of systemic inflammation in patients, playing an important role in recognizing the underlying mechanisms of diseases and thus potentially guiding treatment.

Association of intra-operative red blood cell transfusion on the systemic immune index and recovery in patients undergoing cesarean section: a large propensity score-matched study.

Post-partum hemorrhage (PPH) is a leading cause of maternal death worldwide. However, the effect of blood transfusion in patients undergoing cesarean section remains unclear. The analysis was based on the retrospective evaluation of the pre- and post-operative data for 1231 patients who underwent a cesarean section at our hospital between January 2016 and June 2020. Patients were classified into the blood transfusion group (BT) and the no blood transfusion group (NBT) based on their intra-operative blood transfusion status. After propensity score matching, 322 patients were included in both groups and between-group differences in length of hospital stay (LOS), perioperative systemic inflammation indicators, and post-operative complications were evaluated. The LOS was longer in the BT (median, 6.6days) than the NBT (median, 4.2days) group (P = 0.026). The post-operative complication rate was higher for the BT than NBT group, as follows: vomiting, 3.2% vs. 4.9%, P = 0.032; fever, 5.41% vs. 2.24%, P = 0.032; wound complications, 15.44% vs. 10.45%, P = 0.028; and intestinal obstructions, 5.88% vs. 2.75%, P = 0.034. Systemic inflammation indicators increased significantly, from the pre-operative baseline, for both groups at post-operative day (POD) 1 and POD3. On multivariate analysis, intra-operative blood transfusion was associated with a longer LOS (hazard ratio, 1.52; 95% confidence interval, 1.07-2.25). Intraoperative blood transfusion for cesarean section was associated with increased levels of systemic inflammation indicators, higher post-operative complication rates, and prolonged hospital stay.

Impact of Blood-Count-Derived Inflammatory Markers in Psoriatic Disease Progression.

Psoriasis is a chronic immune-mediated disease, linked to local and systemic inflammation and predisposing patients to a higher risk of associated comorbidities. Cytokine levels are not widely available for disease progression monitoring due to high costs. Validated low-cost and reliable markers are needed for assessing disease progression and outcome. This study aims to assess the reliability of blood-count-derived inflammatory markers as disease predictors and to identify prognostic factors for disease severity. Patients fulfilling the inclusion criteria were enrolled in this study. Patients were divided into three study groups according to disease severity measured by the Body Surface Area (BSA) score: mild, moderate, and severe psoriasis. White blood cell count (WBC), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), derived neutrophil-to-lymphocyte ratio (d-NLR), systemic immune index (SII), systemic inflammation response index (SIRI), and aggregate index of systemic inflammation (AISI) positively were correlated with disease severity (p < 0.005). d-NLR, NLR, and SII are independent prognostic factors for mild and moderate psoriasis (p < 0.05). d-NLR is the only independent prognostic factor for all three study groups. Moderate psoriasis is defined by d-NLR values between 1.49 and 2.19. NLR, PLR, d-NLR, MLR, SII, SIRI, and AISI are useful indicators of systemic inflammation and disease severity in psoriasis.

Inflammatory Indicators in Peripheral Blood in Sudden Sensorineural Hearing Loss Patients With Different Audiogram Shapes.

Objective: A retrospective study was conducted to explore the immune-inflammatory responses in sudden sensorineural hearing Loss (SSNHL) patients with different audiogram shapes. Methods: One hundred and ten inpatients with SSNHL were assigned to 4 subgroups according to the audiogram shape and treated with systemic methylprednisolone. The numbers of white blood cells, neutrophils, lymphocytes, platelets, and monocytes were counted. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and the monocyte-to-lymphocyte ratio (MLR) were calculated and statistically analyzed. Results: Neutrophil-to-lymphocyte ratio, MLR, and systemic immune index (SII) of SSNHL patients were significantly higher than the control group, while PLR was not statistically significant. There were no statistical differences in NLR, PLR, MLR, and SII among the 4 subgroups. Conclusion: Immune-inflammatory response may be a common pathogenesis in all SSNHL patients with different audiogram shapes. The predictive value of these hematologic markers needs further research in the future.

Prognostic Value of Inflammatory Markers in Nasopharyngeal Carcinoma Patients in the Intensity-Modulated Radiotherapy Era.

PurposeInflammatory markers have been widely used in various cancers, but rarely in nasopharyngeal carcinoma (NPC). Here, we evaluated the prognostic value of pretreatment neutrophil-to-lymphocyte ratio (NLR), platelet-lymphocyte-ratio (PLR), systemic immune index (SII), and systemic inflammation response index (SIRI) on NPC in the intensity-modulated radiotherapy (IMRT) era.MethodsWe retrospectively analyzed data from NPC patients from the Renmin Hospital of Wuhan University, between January 2012 and July 2020. We used Chi-square test or Fisher’s exact test to compare the baseline characteristics, then applied Kaplan–Meier (K-M) survival analysis to compare the overall survival (OS) and progression-free survival (PFS) rates. Multivariate Cox proportional risk models were applied to identify independent prognostic factors.ResultsWe enrolled a total of 342 NPC patients and found optimal cut-off values of 2.65, 184.91, 804.08, and 1.34 for NLR, PLR, SII, and SIRI, respectively. K-M survival analysis revealed that high NLR, PLR, SII, and SIRI were significantly associated with worse OS and PFS relative to those in the low groups. Results from univariate Cox analysis showed that clinical, T, and M stages, as well as NLR, PLR, SII, and SIRI were associated with OS, whereas age, alongside the aforementioned parameters, was associated with PFS. Moreover, multivariate Cox analysis showed that age ≥49 years (HR=2.48, 95% CI=1.21–5.05, P=0.013) and M1 stage (HR=3.84, 95% CI=1.52–9.73, P=0.013) were independent prognostic factors for OS, whereas SIRI ≥1.34 (HR=1.91, 95% CI=1.05–3.47, P=0.034) and M1 stage (HR=2.91, 95% CI=1.44–5.86, P=0.003) were independent prognostic factors for PFS.ConclusionOverall, our findings indicated that high NLR, PLR, SII, and SIRI were significantly associated with poor OS and PFS in NPC patients. High SIRI may be an independent risk factor for PFS of NPC patients in the IMRT era.

Clinical laboratory features of Meigs' syndrome: a retrospective study from 2009 to 2018.

Meigs' syndrome (MS), a rare complication of benign ovarian tumors, is easily misdiagnosed as ovarian cancer (OC). We retrospectively reviewed the clinical laboratory data of patients diagnosed with MS from 2009 to 2018. Serum carbohydrate antigen 125 and HE4 levels were higher in the MS group than in the ovarian thecoma-fibroma (OTF) and healthy control groups (all P < 0.05). However, the serum HE4 levels were lower in the MS group than in the OC group (P < 0.001). A routine blood test showed that the absolute counts and percentages of lymphocytes were significantly lower in the MS group than in the OTF and control groups (all P < 0.05). However, these variables were higher in the MS group than in the OC group (both P < 0.05). The neutrophil-to-lymphocyte ratio (NLR) was also significantly lower, whereas the lymphocyte-to-monocyte ratio was higher in the MS group than in the OC group (both P < 0.05). The NLR, platelet-to-lymphocyte ratio, and systemic immune index were significantly higher in the MS group than in the OTF and control groups (all P < 0.05). The hypoxia-inducible factor-1 mRNA levels were also significantly higher, whereas the glucose transporter 1, lactate dehydrogenase, and enolase 1 mRNA levels were lower in peripheral CD4+ T cells obtained preoperatively in a patient with MS than those in patients with OTF, patients with OC, and controls (all P < 0.05). The expression of these four glucose metabolism genes was preferentially restored to normal levels after the tumor resection of MS (P < 0.001). These clinical laboratory features can be useful in improving the preoperative diagnostic accuracy of MS.

A role for IL-4 in immunologically mediated enteropathy.

A number of clinical enteropathies are associated with a local cell-mediated immune (CMI) response, and experimental evidence indicates that cytokines are responsible for the intestinal pathology. We show here that depletion of IL-4 using MoAb or a soluble form of the IL-4 receptor (IL-4R) prevents the jejunal manifestations of a proliferative form of murine graft-versus-host reaction (GVHR) characterized by crypt hyperplasia and recruitment of intraepithelial lymphocytes (IEL). Depletion of IL-4 did not prevent the appearance of villus atrophy in a destructive model of GVHR, and had no effect on any indices of systemic immunity. These results indicate that IL-4 may play a selective role in mediating proliferative aspects of intestinal immunopathology, and suggest that this cytokine may provide a useful target for immunotherapy.
