RESUMO

Background: Early identification of patients who will benefit from immune checkpoint inhibitors (ICIs) has recently become a hot issue in cancer immunotherapy. Peripheral cytokines are key regulators in the immune system that can induce the expression of immune checkpoint molecules; however, the association between peripheral cytokines and the efficiency of ICIs remains unclear. Methods: A systematic review was conducted in several public databases from inception through 3 February 2022 to identify studies investigating the association between peripheral cytokines (i.e., IL-1ß, IL-2, IL-2RA, IL-2R, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IL-15, IL-17, TNF-α, IFN-γ, and TGF-ß) and ICI treatment. Survival data, including overall survival (OS) and/or progression-free survival (PFS), were extracted, and meta-analyses were performed. Results: Twenty-four studies were included in this analysis. The pooled results demonstrated that the pretreatment peripheral levels of IL-6 (univariate analysis: HR = 2.53, 95% CI = 2.21-2.89, p < 0.00001; multivariate analysis: HR = 2.21, 95% CI = 1.67-2.93, p < 0.00001) and IL-8 (univariate analysis: HR = 2.17, 95% CI = 1.98-2.38, p < 0.00001; multivariate analysis: HR = 1.88, 95% CI= 1.70-2.07, p < 0.00001) were significantly associated with worse OS of cancer patients receiving ICI treatment in both univariate and multivariate analysis. However, high heterogeneity was found for IL-6, which might be attributed to region, cancer type, treatment method, sample source, and detection method. Conclusion: The peripheral level of IL-8 may be used as a prognostic marker to identify patients with inferior response to ICIs. More high-quality prospective studies are warranted to assess the predictive value of peripheral cytokines for ICI treatment.

RESUMO

Objective: To analyze the level and influence factors of inflammatory factors among electrical workers in Hainan Province. Methods: A total of 509 electrical workers were selected as the research subjects with random cluster sampling in September 2020. Basic information was collected by questionnaire, the serum IL-6, IL-8 and TNF-α levels of the subjects were detected by Luminex.Mann-Whitney U test and Kruskal-wallis H test were used for univariate analysis. Ordinal logistic regression analysis was used for potential influencing factors of the level of inflammatory factors. Results: The median concentrations of IL-6, IL-8 and TNF-α in serum were 2.78, 9.77 and 8.18 pg/ml. Compared with women, male was a risk factor for the increase of IL-6 levels (OR=1.80, 95%CI: 1.08~3.00, P=0.024) . Compared with 51-60 years old, 21-31 years old (OR=0.27, 95%CI: 0.18~0.42, P<0.001) , 31-41 years old (OR=0.27, 95%CI: 0.17~0.43, P<0.001) and 41-51 years old (OR=0.64, 95%CI: 0.41~0.99, P=0.043) were protective factors for the increase of IL-8 level. Compared with day shift workers, shift work was a risk factor for the increase of IL-8 level (OR=1.73, 95%CI: 1.21~2.48, P=0.003) . Compared with women, male was a risk factor for the increase of TNF-α levels (OR=2.87, 95%CI: 1.70~4.86, P<0.001) . Compared with workers who exposed to 7 or more occupational hazard factors, exposed to 1~3 (OR=0.53, 95%CI: 0.30~0.92, P=0.024) occupational hazard factors were protective factors for the increase of TNF-α levels. Conclusion: The level of inflammatory factors was related to sex, age, work system and occupational environment, which can provide basic data for follow-up research on occupational population.

RESUMO

OBJECTIVE: To investigative the detection value of EB virus DNA (EBV-DNA), interleukin-2 (IL-2), and interleukin-6 (IL-6) level in peripheral blood of children with infectious mononucleosis (IM). METHODS: A total of 59 children clinically confirmed with IM in Anhui Provincial Children's Hospital from January 2018 to September 2020 were enrolled as IM group, while other 30 healthy children undergoing physical examination during the same period were enrolled as healthy group. The level of EBV-DNA load, IL-2, and IL-6 were compared between the two groups, and their diagnostic values for IM children were explored. According to the median level of EBV-DNA load, positive children were divided into high viral load group and low viral load group. The hepatomegaly and splenomegaly, and levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), IL-2, and IL-6 were compared between the two groups. The relationship between EBV-DNA load and IL-2, IL-6 levels were explored. RESULTS: The positive rate of EBV-DNA was 67.80% in IM group, which was significantly higher than 10.00% in healthy group (P<0.001), and the levels of serum IL-2 and IL-6 were also significantly higher than healthy group (P<0.001). The results of ROC curve analysis showed that AUC of IL-2 combined with IL-6 and EBV-DNA load was 0.948, which was significantly greater than that of IL-2, IL-6, and EBV-DNA load alone (0.847, 0.728, 0.789) (P<0.001). The cut-off value of IL-2 and IL-6 was 15.545 pg/ml and 56.560 pg/ml, respectively. Both the proportions of cases with moderate to severe hepatomegaly and splenomegaly in high viral load group were significantly higher than those in low viral load group (P<0.01, P<0.05). The levels of ALT, AST, and IL-2 in high viral load group were significantly higher than those in low viral load group (P<0.001), as well as IL-6 (P<0.01). In high and low viral load groups, EBV-DNA load was positively correlated with IL-2 and IL-6 (in high viral load group, rIL-2=0.598, rIL-6=0.416; in low viral load group, rIL-2=0.621, rIL-6=0.527, P<0.001). CONCLUSION: The detection of EBV-DNA load combined with IL-2 and IL-6 can improve the diagnostic accuracy of IM, and EBV-DNA load, IL-2 and IL-6 levels are related to the disease progression.

RESUMO

BACKGROUND: The role of the long non-coding RNAs (lncRNAs) in the pathogenesis of systemic lupus erythematosus (SLE) is mostly unknown, despite increasing evidence that lncRNAs extensively participate in physiological and pathological conditions. AIM: To detect the level of lncRNA-Cox2, HOTAIR, IL-6, and MMP-9 in the serum of SLE patients and to correlate these levels with disease activity and patients' clinical and laboratory data to evaluate the value of these biomarkers for SLE diagnosis and assessment of disease activity. METHODS: Blood samples from 58 SLE patients, and 60 healthy controls (HCs) were used for detection of lncRNAs-Cox2 and HOTAIR expression levels by real-time polymerase chain reaction. Both IL-6 and MMP-9 serum levels were assayed by enzyme-linked immunosorbent assay. Lupus activity was assessed with the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). RESULTS: The serum expression levels of lncRNA-Cox2 and HOTAIR were significantly up-regulated in SLE patients vs HCs (fold change [median (IQR) was 1.29(0.81-1.71, P<0.0001) and 2.68(0.95-3.67), P = 0.038) for lncRNA-Cox2 and HOTAIR, respectively. Serum levels of both IL-6 and MMP-9 were significantly high in SLE patients compared with HCs (P≤0.001 for each). The up-regulated lncRNA-Cox2 was positively associated with the presence of neurological manifestations in SLE patients (P = 0.007). Furthermore, HOTAIR expression level had significantly positive correlation with IL-6 (r = 0.578, P<0.0001), MMP-9 level (r = 0.762, P<0.0001), nephritis grades (r = 0.296, P = 0.024) and proteinuria (r = 0.287, P = 0.035). LncRNA-Cox2 showed sensitivity and specificity 72.4%, and 100.0% respectively. HOTAIR sensitivity was 60.3%, and specificity was 100.0%. By multiple logistic regression analysis, lncRNA-Cox2 and HOTAIR were found as SLE independent predictors. CONCLUSION: LncRNA-COX2 and HOTAIR can be used as new non-invasive biomarkers for the diagnosis of SLE.

RESUMO

Several studies suggest a link between acute changes in inflammatory parameters due to an endotoxin or (psychological) stressor and the brain's stress response. The extent to which basal circulating levels of inflammatory markers are associated with the brain's stress response has been hardly investigated so far. In the present study, baseline plasma levels of the cytokine interleukin (IL)-6 were obtained and linked to neural markers of psychosocial stress using a modified version of the Montreal Imaging Stress Task in a sample of N = 65 healthy subjects (N = 39 female). Of three a-priori defined regions of interest - the amygdala, anterior insula, and anterior cingulate cortex - baseline IL-6 was significantly and negatively associated with stress-related neural activation in the right amygdala and left anterior insula. Our results suggest that baseline cytokines might be related to differences in the neural stress response and that this relationship could be inverse to that previously reported for induced acute changes in inflammation markers.

RESUMO

BACKGROUND: Postoperative pneumonia (PP) is one of the most common complications after cardiac surgery. This study was designed to access the diagnostic value of interleukin-6 (IL-6) for pneumonia within the first 5 days after cardiac surgery in adults. METHOD: This prospective observational study enrolled 694 patients who admitted to our center from 10 October 2020 to 30 June 2021. Blood samples were collected after admission and on five consecutive days after surgery to measure IL-6, procalcitonin (PCT), C-reactive protein (CRP) and white blood cells (WBC) respectively. Combined with clinical data, we assessed the diagnostic performance of different biomarkers using univariate and multifactorial analyses as well as receiver operating characteristic curves (ROC) and the area under the curve (AUC). RESULT: Finally, 68 patients were diagnosed with PP (PP Group). In addition, 626 cases were assigned to the control group (Non-PP Group). From postoperative day 1 (POD1) to day 5, IL-6 and PCT levels showed higher diagnostic value (P < 0.001, P < 0.05, respectively); meanwhile, there was no difference in white blood cell counts between the two groups; CRP showed some value from POD2 onwards (P < 0.001). Among these biomarkers, IL-6 on POD1 [AUC: 0.78, 95% confidence interval (CI): 0.71-0.83], IL-6 on POD2 (AUC: 0.77, 95% CI: 0.71-0.82) and CRP levels on POD3 (AUC: 0.77, 95% CI: 0.70-0.84) had the highest diagnostic value. Multivariate analysis found that smoking status [odds ratio(OR): 7.79, 95% CI: 3.05, 19.88, p < 0.001], drinking status (OR: 22.68, 95% CI: 9.29, 55.37, p < 0.001) and hypertension (OR: 2.85, 95% CI: 1.28, 6.35, p = 0.011), IL-6 on POD2 (OR: 1.01, 95% CI: 1.00, 1.01, p = 0.018), mechanical ventilation time (OR: 1.03, 95% CI: 1.00, 1.05, p = 0.040) and intensive care unit stay time (OR: 1.01, 95% CI: 1.00, 1.02, p < 0.001) were independent risk factors for postoperative pneumonia. CONCLUSION: Smoking, drinking, hypertension, prolonged duration of mechanical ventilation and intensive care unit stay, and IL-6 on POD2 were independent risk factors for pneumonia after cardiovascular surgery. IL-6 level on POD2 may serve as a promising indicator, better than WBC, PCT and CRP.

RESUMO

Objective To investigate the role and mechanism of long noncoding RNA (lncRNA) LOC102640791 in sepsis inflammatory response. Methods The mice model of sepsis was established by intraperitoneal injection of lipopolysaccharide (LPS). The cell model of sepsis was established by treating of RAW264.7 macrophages with LPS. Mice or cells were randomly divided into the control group and the LPS group. The levels of lncRNA and miRNA in serum were detected by microarrays. The levels of LOC102640791 and miR-320-3p were tested by the real time quantitative PCR. The levels of TNF-α, IL-6, IL-8, IL-4 and IL-10 in serum and cell culture supernatant of RAW264.7 were detected by the ELISA. Luciferase reporter gene technology was used to verify the relationship between LOC102640791 and miR-320-3p. Results Compared with the control group, the LPS group had lower expression of LOC102640791 and higher expression of miR-320-3p. Compared with the LPS group, the LPS group with high expression of LOC102640791 and the LPS group with low expression of miR-320-3p had higher expression of pro-inflammatory factors (TNF-α, IL-6 and IL-8) and lower expression of anti-inflammatory factors (IL-4 and IL-10). Wild type LOC102640791 can inhibit the luciferase activity of miR-320-3p. Conclusion LOC102640791 alleviates sepsis inflammatory response by sponging miR-320-5p.

RESUMO

BACKGROUND: Vitamin D has anti-inflammatory efficacy against ulcerative colitis (UC), however, the mechanism is yet little understood. OBJECTIVE: To investigate the immunomodulatory effects of vitamin D against the UC, and to explore the potential downstream mechanisms. MATERIALS AND METHODS: Serum vitamin D, Interferon-γ (IFN-γ) and Interleukin (IL)-17 levels of the patients with UC were quantified using enzyme-linked immunosorbent assay (ELISA). Long non-coding RNAs (lncRNAs) levels were determined by using quantitative reverse-transcription polymerase chain reaction (qRT-PCR). Peripheral blood mononuclear cells (PBMCs) were collected from healthy control subjects, stimulated with CD4+ T lymphocytes or helper T cells 17(Th17) differentiation conditions, and then exposed to calcitriol (vitamin D active form) or certain lentiviral treatment, followed by subsequent molecular level testing. For in vivo assay, mice were given 3% dextran sulfate sodium (DSS) to induce colitis. RESULTS: Compared with the control group, vitamin D levels in the UCs were statistically lower, and there was a negative correlation between IL-17 and vitamin D in the UCs. The lncRNA OIP5-AS1 could decrease under calcitriol treatment in both CD4+ T cells and Th17 differentiation. The lncRNA OIP5-AS1 was a microRNA (miR)-26a-5p sponge and therefore modulated the Th17 cells and IL-6 expression. The lncRNA OIP5-AS1/miR-26a-5p/IL-6 axis mediated the regulation of calcitriol-induced Th17 differentiation. Calcitriol had therapeutic effects on the UC mouse models by regulating the lncRNA OIP5-AS1 related pathway. CONCLUSION: Vitamin D might have anti-inflammatory potential in the treatment of the UC.

RESUMO

BACKGROUND: Concomitant signals from IL-6 and TGF-ß have a central role in the Th17 cells development and differentiation, and these cells are the main promoters of demyelinating inflammation in the central nervous system (CNS) resulting in multiple sclerosis (MS). OBJECTIVES: To evaluate the simultaneous IL-6 and TGF-ß gene and their receptor protein expression in patients with Relapsing-Remitting (RR)-MS. MATERIALS AND METHODS: IL-6 and TGF-ß mRNA and their receptor expression on the surface of CD4+T cells were evaluated using real-time PCR (RT-PCR) and flow cytometry, respectively. RESULTS: The IL-6 mRNA expression in patients with RRMS was significantly higher than in the controls (p= 0.019). When patients who did not receive any other treatment were compared with the controls, the significant difference was substantial (p=0.006). The TGF-ß mRNA expression in patients was lower than in the controls (p = 0.03). However, in patients receiving IFNß, it increased compared with the other patients (p= 0.036). There was no difference in cytokine receptor expression between patients and the control group. CONCLUSION: Our data conclude an increase and decrease in mRNA expression levels of IL-6 and TGF-ß in patients with RRMS, respectively. Moreover, there were no significant differences in receptor expression of either cytokines. Based on our data the balance of TGF and IL-6 appears to have a positive impact on the disease control.

RESUMO

CXCL13 in cerebrospinal fluid has gradually become an established biomarker for Lyme neuroborreliosis (LNB), however the diagnostic performance of CXCL13 may be improved by the addition of IL-6, a non-specific infection biomarker. The aim of this study was to measure the concentrations of CXCL13 and IL-6 in cerebrospinal fluid, in the attempt to evaluate the diagnostic performance of these two biomarkers, in the differentiation between definite and possible LNB, as well as between LNB and other neuroinfections. This study used a cross-sectional design to quantify the levels of CXCL13 and IL-6 in cerebrospinal fluid (CSF) specimens from consecutive patients examined for central nervous system (CNS) infections at Lillebaelt Hospital in the Region of Southern Denmark. CXCL13 and IL-6 were measured simultaneously using the Bio-Plex 200 multiplex Cytokine Immunoassay System (Bio-Rad). Based on clinical and paraclinical findings, we grouped patients into six separate groups: definite LNB, possible LNB, Viral CNS infection, non-Borrelia Bacterial CNS infection, Other CNS disease (with pleocytosis) and Negative (without pleocytosis). A combined interpretation of four variables (leukocyte cell counts, protein concentration, CXCL13 and IL-6 concentrations in CSF) is presented using principal component cluster analysis. We included by chart review 390 patients discharged with definite LNB (n = 31), possible LNB (n = 10), confirmed Viral or non-Borrelia Bacterial CNS infection (n = 34), Other CNS disease (n = 58), and Negative (n = 257) for CXCL13 and IL-6 analysis. Principal component analysis (PCA) revealed three distinct clusters based on leukocyte cell counts, protein concentration, CXCL13 and IL-6 concentrations in CSF from 380 included patients (10 possible LNB patients excluded). The clusters clearly differentiate the groups: definite LNB, non-Borrelia Bacterial CNS infection and Negative (without pleocytosis). A receiver operating characteristic (ROC) curve comparing LNB patients (n = 31) and all non-LNB conditions with CSF pleocytosis (n = 99) indicated an optimal CXCL13 cut-off value of 50.7 pg/mL, resulting in a sensitivity and a specificity of 93.6 and 91.1%, respectively. The ROC analysis comparing patients with confirmed non-LNB CNS infection (n = 34) and all others with CSF pleocytosis (n = 97) resulted in an optimal IL-6 cut-off value of 111.5 pg/mL, yielding a sensitivity and a specificity of 78.8% and 82.5% respectively. Of the ten possible LNB patients, three cases (with CXCL13 levels above cut-off) fall within the LNB cluster, and one case is just outside, providing some laboratory support for the diagnosis of LNB. The remaining six possible LNB patients (with CXCL13 levels below the 50.7 cut-off) had little support for the diagnosis of LNB in the PCA-plot. The results of this study confirm that CXCL13 is a valuable supplement for diagnosis of LNB, and that the combination of CXCL13 and IL-6 may be used to differentiate cases of LNB from other CNS infections. Furthermore, IL-6 can be of differential diagnostic value when evaluating patients with possible LNB.

RESUMO

The death of a spouse is associated with maladaptive immune alterations; grief severity may exacerbate this link. We investigated whether high grief symptoms were associated with an amplified inflammatory response to subsequent stress among 111 recently bereaved older adults. Participants completed a standardized psychological stressor and underwent a blood draw before, 45 min after, and 2 hr after the stressor. Those experiencing high grief symptoms (i.e., scoring > 25 on the Inventory of Complicated Grief) experienced a 45% increase in interleukin-6 (IL-6; a proinflammatory cytokine) per hour, whereas those experiencing low grief symptoms demonstrated a 26% increase. In other words, high grief was related to a 19% increase in IL-6 per hour relative to low grief. The grief levels of recently bereaved people were associated with the rate of change in IL-6 following a subsequent stressor, above and beyond depressive symptoms. This is the first study to demonstrate that high grief symptoms promote inflammation following acute stress.

RESUMO

Background: IL-6 plasma concentration (IL-6PC) reflects the systemic inflammation related to exercise intensity level. This study aims to describe the IL-6PC kinetics during a long-distance running race. IL-6PC was measured in 20 male runners before (0 km), at each refreshment point (at 21 and 53 km, i.e., k21 and k53, respectively) and at the end of an 80 km long-distance run (k80). Methods: IL-6PC variations (absolute and relative values in each of the three sections (S)) were calculated over S1 (0_k21), S2 (k21_k53) and S3 (k53_k80) and compared with the exercise intensity (duration*race speed) within each section. Results: The mean IL-6PC increased during the run: 2.1 ± 0.6 ng.L-1 at 0 km, 21.0 ± 11.3 ng.L-1 at k21, 38.9 ± 13.0 ng.L-1 at k53 and 49.8 ± 11.9 ng.L-1 at k80. Exercise intensity increased between S1 (24.2 ± 0.5) and S2 (51.9 ± 3.2) (p = 0.04) but not between S2 and S3 (67.4 ± 4.5) (p = 0.69). IL-6PC variation was associated with exercise intensity within S1 (p = 0.03) and S2 (p = 2 × 10-3) and showed at least a trend within S3 (p = 0.06). Conclusions: IL-6PC increases that occur during the early stages of a long-distance run are associated with the running intensity, and then IL-6PC remain stable after the reduction in intensity related to the decrease in running speed.

RESUMO

STUDY OBJECTIVES: To examine the association between sleep midpoint and inflammation in a population with a large proportion of individuals diagnosed with obstructive sleep apnea syndrome (OSAS), a group that is already prone to increased inflammation. METHODS: Subjects from the Cleveland Family Study underwent overnight polysomnography and completed surveys on sleep habits. Morning and evening blood samples were collected and assayed for proinflammatory biomarkers interleukin (IL)-1, IL-6, and tumor necrosis factor α (TNF-α). Linear regression models were used, adjusting for potential confounders and sleep duration. RESULTS: The study population included 587 adults (52.3% with OSAS). Mean ± standard deviation weekday sleep midpoint was 3.52 ± 2.09 (3:31 am) and weekend sleep midpoint was 4.46 ± 1.69 (4:28 am). The Mean difference between weekday and weekend sleep midpoint (social jetlag) was 0.94 ± 2.08 hours. After adjusting for OSA severity, greater social jetlag was associated with higher levels of the inflammatory cytokine IL-1 (beta: 0.435 pg/mL, 95% confidence interval [CI]: 0.091 to 0.779). Additionally, later timing of sleep during both the weekdays and the weekends was associated with increased levels of IL-6 (weekday beta: 0.182 pg/mL; 95% CI: 0.013 to 0.350; and weekend beta: 0.188 pg/mL; 95% CI: 0.004 to 0.373). No trends were observed with TNF-α and any sleep exposure. CONCLUSIONS: Later sleep timing was associated with elevated levels of IL-6 while increased social jetlag was associated with elevated levels of IL-1. Our results indicate that later sleep schedules and increased social jetlag may lead to higher inflammation, even after controlling for OSA severity.

RESUMO

Objective: To assess the prognostic value of serum interleukin-6 (IL-6), nuclear factor-κB (NF-κB), and monocyte chemoattractant protein 1(MCP-1) assay in patients with diabetic nephropathy. Methods: From May 2019 to March 2020, 104 patients with diabetic nephropathy treated in our institution assessed for eligibility were recruited and assigned at a ratio of 1 : 1 to either the observation group ([urinary albumin excretion rate (UAER)] of 30 mg-300 mg/24 h) or the research group ([UAER] >300 mg/24 h). IL-6, MCP-1, renal function indices, and NF-κB levels were determined, and their correlation with DN was analyzed. Logistic regression was used to analyze the influencing factors of end-stage renal disease in patients with diabetic nephropathy. The receiver operating characteristic (ROC) curve was drawn, and the area under the curve (AUC) was calculated to analyze the predictive value of combined detection of IL-6, MCP-1, and NF-κB in the prognosis of patients with diabetic nephropathy. Results: The eligible patients with UAER of 30 mg-300 mg/24 h were associated with significantly higher levels of IL-6, MCP-1, NF-κB, blood urea nitrogen (BUN), and serum creatinine (Scr) versus those with UAER >300 mg/24 h (P < 0.05). During the follow-up, a total of 38 patients progressed to end-stage renal diseases. Eligible patients with end-stage renal diseases showed significantly higher serum IL-6, MCP-1, and NF-κB levels versus those without end-stage renal diseases (P < 0.05). Serum IL-6, MCP-1, and NF-κB are independent risk factors for the occurrence of end-stage renal disease in patients with diabetic nephropathy. The AUCs of IL-6, MCP-1, and NF-κB for predicting the prognosis of patients with diabetic nephropathy were 0.562, 0.634, and 0.647, respectively, and the AUC of the three combined detection for predicting the prognosis of patients with diabetic nephropathy was 0.889. Conclusion: Serum IL-6, NF-κB, and MCP-1 levels are closely related to renal injury and poor prognosis in patients with diabetic nephropathy, and the combined assay is valuable for assessing patients' condition and prognosis.

RESUMO

Prior studies have outlined C-reactive protein (CRP) within the first 5 d following total hip arthroplasty (THA) as an inappropriate indicator of an early periprosthetic joint infection (PJI). Recently, interleukin-6 (IL-6), as a potential inflammatory marker following total joint arthroplasty (TJA), has gained increasing interest, particularly due to its considerably shorter half-life. The aim of the present study was to assess IL-6 measured on postoperative day 3 following TJA as a prediction marker of early onset PJI. 7,661 patients, who underwent total hip or knee arthroplasty (THA, TKA) at a single institution between 2016 and 2019, were evaluated. Serum IL-6 values were measured on postoperative day 3 and compared between patients, with and without early onset PJI in the postoperative follow-up, matched for age, gender, Surgical Site Infection Risk Score and Charlson comorbidity index. Overall (n = 7,661), there was no statistically significant difference in serum IL-6 levels comparing patients with and without early onset PJI following THA [38.9 pg/ mL vs. 32.0 pg/mL, p = 0.116] and TKA [30.6 pg/mL vs. 28.2 pg/mL, p = 0.718]. Male gender and high body mass index were associated with an increased risk of early onset PJI following THA (p = 0.027, p = 0.002). Matched cohort analysis (n = 86) showed no statistically significant difference in serum IL-6 levels between patients with and without early onset PJI following THA (p = 0.680) and TKA (p = 0.910). Serum IL-6 values on postoperative day 3 following THA or TKA could not predict early onset PJIs.

RESUMO

OBJECTIVES: To study the significance of interleukin-6 (IL-6) and interleukin-27 (IL-27) in the differential diagnosis of acute respiratory distress syndrome (ARDS) and neonatal respiratory distress syndrome (NRDS) in preterm infants. METHODS: The preterm infants with the manifestation of respiratory distress who were treated in the Neonatal Diagnosis and Treatment Center, Children's Hospital of Chongqing Medical University, from March to November 2021, were enrolled in this prospective study. According to the diagnosis results, they were divided into two groups: ARDS group (n=18) and NRDS group (n=20). ELISA was used to measure the plasma levels of IL-6 and IL-27. The receiver operating characteristic (ROC) curve was used to analyze the value of each index in the diagnosis of ARDS. RESULTS: The ARDS group had significantly higher plasma levels of IL-6 and IL-27 than the NRDS group (P<0.05). The ROC curve analysis showed that IL-6 had an area under the ROC curve (AUC) of 0.867 for the diagnosis of ARDS, with a sensitivity of 61.1% and a specificity of 95.0% at the cut-off value of 56.21 pg/mL. The ROC curve analysis also showed that IL-27 had an AUC of 0.881 for the diagnosis of ARDS, with a sensitivity of 83.3% and a specificity of 80.0% at the cut-off value of 135.8 pg/mL. CONCLUSIONS: Plasma IL-6 and IL-27 can be used as biological indicators for early differential diagnosis of ARDS and NRDS in preterm infants.

RESUMO

Interleukin-6 (IL-6) is a pleiotropic cytokine involved in several mechanisms, and the alteration of IL-6 signaling leads to the overactivation of various processes including immunity, inflammation, and hemostasis. Although IL-6 increase has been documented in venous thromboembolic diseases, the exact involvement of IL-6 signaling in deep vein thrombosis (DVT) has not been fully understood. Consequently, we investigated the involvement of IL-6 trans-signaling in inflammatory events occurring in DVT, focusing on the role of the interleukin-6 receptor (IL6-R) Asp358Ala variant. The circulating levels of IL-6, soluble IL6-R (sIL6-R), and soluble glycoprotein 130, as well as the Asp358Ala genotyping, were assessed in a consecutive cohort of DVT patients and healthy controls. The results indicated that IL-6 was higher in DVT compared to controls. Moreover, sIL6-R levels were strongly correlated to Asp358Ala variant in both groups, showing a high frequency of this mutation across all samples. Interestingly, our results showed a high frequency of both Asp358Ala mutation and raised IL-6 levels in DVT patients (OR = 21.32; p ≤ 0.01), highlighting that this mutation could explain the association between IL-6 overactivation and DVT outcome. Overall, this study represents a proof of concept for the targeting of IL-6 trans-signaling as a new strategy for the DVT adjuvant therapy.

RESUMO

BACKGROUND: Local anesthesia has been recommended for percutaneous endoscopic lumbar discectomy (PELD) in recent years; however, the efficacy, including oxidative stress, inflammatory reactions and ventilation effects, when intravenous dexmedetomidine (DEX) is administered during PELD has not been described. METHODS: Sixty adult patients undergoing PELD were randomly allocated to either an intravenous DEX sedation group (Group A) or a normal saline group (Group B). Respiratory data, including minute ventilation (MV), tidal volume (TV), and respiratory rate (RR), were recorded using a respiratory volume monitor (RVM), and peripheral oxygen saturation (SpO2) was monitored by pulse oximetry. The visual analog score (VAS) was used to assess the level of pain. The serum levels of inflammatory biomarkers including interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were to assess inflammatory reactions. The serum levels of oxidative stress biomarkers including malondialdehyde (MDA) and glutathione peroxidase (GSH-PX) were also recorded to evaluate oxidative stress. RESULTS: There were no significant differences in RR, MV, TV and SpO2 between the two groups at any time point (P > 0.05). Group B exhibited lower serum levels of GSH-PX (P < 0.0001) and higher serum levels of MDA (p < 0.0001) than Group A at the end of surgery. Twenty-four hours after surgery, Group B exhibited higher serum levels of IL-6 (P = 0.0033), TNF-α (P = 0.0002), and MDA (P < 0.0001) and lower serum levels of GSH-PX (P < 0.0001) than Group A. In addition, Group A exhibited lower VAS (P < 0.0001) than Group B during surgery. CONCLUSIONS: DEX administration using RVM not only provides analgesia without ventilatory depression but also alleviates oxidative stress and inflammatory reactions in patients undergoing PELD.

RESUMO

Objective: The study is aimed at evaluating the immune-activation state before and after treatment in patients with first-episode depressive disorder (FDD) with evaluating the ILs and CRP levels and further clarifying the association between autoimmunity and the etiology and pathogenesis of FDD. Methods: We designed a case-control study. FDD patients and healthy subjects were enrolled in the FDD group and control group. Serum IL-6, IL-17, and CRP were measured before and after selective serotonin reuptake inhibitor (SSRI) therapy, as well as Hamilton rating scale for depression (HAMD) and life event scale (LES) scores. The correlations between IL-6 and IL-17 and HAMD and LES scores were analysed, and multiple linear regression analysis was performed for HAMD score. Results: 40 FDD patients and 40 healthy subjects were included in the FDD and control group from October 2009 to September 2012. Before treatment, the IL-6 (28.99 ± 5.51, P < 0.001) and IL-17 (41.15 ± 4.80, P < 0.001) in the FDD group were significantly higher than the control group (16.84 ± 3.78 and 21.68 ± 3.72, respectively). The C-reactive protein (CRP) level in two groups was comparable (P = 0.879). After treatment, the IL-6 (18.69 ± 5.07, P < 0.001) and IL-17 (30.67 ± 3.47, P < 0.001) levels and HAMD scores (6.73 ± 4.15) in the FDD group were significantly decreased than before treatment (P < 0.001, respectively). CRP level was slightly increased after treatment without statistically significant (P = 0.239). The HAMD score correlated with IL-6 (r = 0.638, P < 0.001) and IL-17 (r = 0.927, P < 0.001); the total LES and negative LES also correlated with IL-6 (r = 0.226, P < 0.05) (r = 0.366, P <0.001) and IL-17 (r = 0.348, P < 0.001) (r = 0.493, P < 0.001). Multiple linear regression analysis showed that both of the IL-6 and IL-17 had direct impact on HAMD score. Conclusion: The autoimmunity status was overactivated in FDD patients, and serum IL-6 and IL-17 levels had direct impact on the HAMD score. Patients who experienced more negative life events had higher activation level of autoimmunity status and HAMD scores, and serum IL-6 and IL-17 levels can be decreased by SSRI treatment.
