Elevated IL-37 Serum Levels in Patients with Transitional Cell Carcinoma of Bladder

Background: Interleukin-37 (IL-37) is a recently described cytokine that emerges as a natural inhibitor of inflammatory and immune responses. However, IL-37 has not yet been investigated in bladder cancer, and its biological role is unknown. Objective: The purpose of this study was to investigate IL-37 serum levels in patients with bladder cancer and determine whether they were linked to the patients' pathological characteristics. Methods: IL-37 serum levels were measured using a commercial ELISA kit in 60 patients with transitional cell carcinoma (TCC) of the bladder (mean age: 64.55±12.93) and 50 healthy controls (mean age: 62.94±12.69). Non-parametric tests were used for statistical comparisons, and the Cohen's d effect size was calculated to evaluate the practical and clinical significance of the results. Results: Our findings indicated an increasing trend in IL-37 serum levels in patients with TCC (42.77±3.36 pg/ml) in comparison with controls (40.51±7.32 pg/ml, p=0.09). However, IL-37 serum levels were found to be significantly higher in male patients (44.72±3.81 pg/ml) and patients aged ≥70 (46.92±6.77 pg/ml) in comparison with male controls (29.96±3.30 pg/ml, p=0.026) and controls aged ≥70 (23.62±4.43 pg/ml, p=0.009). In comparison to similar controls, Cohen's d effect size for patients aged ≥70 years was found to be 0.90. Conclusion: The findings reveal a higher serum level of IL-37 in patients with TCC, which might be clinically associated with immunosuppression and tumor growth. However, this is a preliminary study, and more research on the biological role of IL-37 and its potential therapeutic effects in bladder cancer is required.

Correlation of Midkine Serum Level with Pro- and Anti-Inflamatory Cytokines in Multiple Sclerosis

Background: Midkine (MK) is a heparin-binding growth factor with promoting effects in inflammatory responses through enhancing leukocytes migration. Objective: To study the correlation between MK serum levels and concentration of inflammatory cytokines in Multiple Sclerosis (MS) patients. Methods: We evaluated the MK level and its relationship with inflammatory cytokines (IL-17 and IL-23) and antiinflammatory ones (IL-10 and TGF-β) in multiple sclerosis (MS) patients. The serum concentrations of MK and cytokines were assessed by ELISA in 32 MS patients in comparison with 32 healthy subjects. Results: Our data showed that the MK concentration in MS patients is lower than healthy controls (341.15 ± 40.71 Pg/ml vs. 620.15 ± 98.61 Pg/ml, respectively, p=0.015). We also observed a significant decrease in IL-10, IL-23, and TGF-β cytokine levels in MS patients. There was a significant correlation between MK and IL-23 concentrations in our study (r = +0.829, p≤0.001). Conclusion: These results confirm a role for MK in inflammatory reactions in MS.     

Serum levels of the regulatory cytokines transforming growth factor-β and interleukin-10 are reduced in patients with discoid lupus erythematosus

T-lymphocytes are believed to play an important role in the pathogenesis of discoid lupus erythematosus (DLE). However, the reasons that lead to loss of tolerance and to development of autoimmunity in DLE remain unclear. In the present paper, we investigated serum levels of the regulatory cytokines transforming growth factor (TGF)-β and interleukin (IL)-10 in 25 newly diagnosed patients with DLE, 15 with systemic lupus erythematosus (SLE), 10 with psoriasis, 10 with atopic dermatitis (AD) and 20 healthy controls (HC). TGF-β serum levels were significantly lower in patients with DLE compared with patients with psoriasis and HC, while no differences were found between DLE, SLE and AD (medians: DLE: 28.49?ng/ml; psoriasis: 42.77?ng/ml; HC: 43.71?ng/ml; DLE vs. psoriasis: p?相似文献   

IL-18 Serum Levels in Patients with Obesity,Prediabetes and Newly Diagnosed Type 2 Diabetes

Background: Obesity and diabetes are related to a chronic low-grade inflammation. As a pro-inflammatory cytokine, IL-18 stimulates various cell types and has pleiotropic functions. Objective: To assess the levels of IL-18 in subjects from the entire spectrum of glycemic disorders. Methods: This study included 387 Caucasians divided into four groups: healthy controls, obese subjects without carbohydrate issues, prediabetic patients, and recently discovered type 2 diabetics. Results: Subject with body mass index ≥30kg/m2 and glycemic disorders showed significantly higher levels of IL-18 (249.77 ± 89.96 pg/ml; 259.01 ± 95.70 pg/ml; and 340.98 ± 127.65 pg/ml) compared with that of the control group (219.47 ± 110.53 pg/ml, p < 0.05). IL-18 also had significant positive associations with some anthropometric parameters, liver enzymes, fasting, post-load glucose, insulin, uric acid, and triglycerides while negative with HDL. The circulating IL-18 levels for differentiating subjects with carbohydrate disturbances and those with metabolic syndrome were determined by ROC analysis. The AUC for the disturbances of the carbohydrate metabolism was 0.597 (p = 0.001; 95% CI = 0.539 - 0.654) and for MS AUC was 0.581 (p = 0.021; 95 % CI = 0.516 - 0.647). Conclusion: Our data indicate that as the levels of IL-18 are increased the carbohydrate tolerance is deteriorated. However, the significance of IL-18 in the progression of diabetes mellitus and subsequent consequences requires further exploration.     

Increased IL-17A in Atrial Fibrillation Correlates with Neutrophil to Lymphocyte Ratio

Background: Atrial Fibrillation (AF) is the most common cardiac arrhythmia and an independent risk factor for stroke among the elderly. A role for inflammation in the atrial remodeling as well as development and recurrence of AF is known. Objective: To compare IL-17A between patients with different types of AF and healthy individuals. Methods: IL-17A was measured in sera of 112 patients and 107 healthy age/sexmatched controls using ELISA assay. In sera of 26 patients with elevated IL-17A (>1 Pg/ml), CCL5 and CCL18 levels were also measured. Results: IL-17A was significantly increased in patients with AF compared to controls (1.28 ± 3.5 vs. 0.19 ± 0.64 Pg/ml, p=0.001). There was no significant difference in the level of IL-17A between different types of AF. IL-17A was significantly higher in patients with a history of coronary artery bypass graft compared to other patients (p=0.01). A significant positive correlation between IL-17A and CCL18 concentration was found (p=0.001). An increase in the Neutrophil/Lymphocyte ratio (NLR) was observed in patients with elevated serum IL-17A compared to other patients (p=0.006). Male patients showed higher increase in NLR (p=0.007) which was accompanied by a decrease in CCL5 (p=0.000) and a marginal increase in CCL18 (p=0.085) compared to females. There was an increase in CCL5 levels in patients receiving Acetylsalicylic Acid (ASA) therapy (p=0.046). Conclusions: The increase in IL-17A levels is related to the AF pathology mediated by neutrophils and monocytes. The current study signifies the role of immune cells and cytokines in the pathology of AF.     

IL-2 and IL-10 levels in induced sputum and serum samples of asthmatics.

BACKGROUND: There is consisting evidence that asthma is associated with airway inflammation. Originally IL-10 and IL-2 were described as lymphokines produced by T cells in mediating cellular infiltration into the airways and continue to be of interest in evaluating asthma pathogenesis. The aim of this study was to evaluate the serum and sputum levels of IL-2 and IL-10 in asthmatic subjects and healthy controls and to correlate disease activity and other clinical indices with concentrations of IL-2 and IL-10 in serum and sputum samples. METHODS: We evaluated cell profiles and IL-2 and IL-10 levels in induced sputum samples and in serum samples of 6 mild, 5 moderate, 7 severe asthmatic patients and 5 healthy controls by using ELISA. RESULTS: The mean IL-2 in sputum samples of asthmatics and controls were 35.3 +/- 13.2 pg/ml and 35.3 +/- 8.4 pg/ml, respectively. The mean IL-2 in serum samples of asthmatics and controls were 42.7 +/- 21.1 pg/ml and 30.3 +/- 2.4 pg/ml, respectively. Both levels did not result in any statistically significant difference between asthmatics and controls. There was no correlation between serum and sputum IL-2 levels, however sputum IL-2 levels correlated with percentage of sputum lymphocytes (p < 0.03, r = 0.51). The mean IL-10 levels in sputum samples of asthmatics and controls were 4.4 +/- 3.3 pg/ml and 3.9 +/- 5.9 pg/ml, respectively, the mean IL-10 level in serum of asthmatics and controls were 4.1 +/- 3.8 pg/ml and 2.3 +/- 2.5 pg/ml, respectively. We could not find statistically significant difference of serum or sputum IL-10 levels between asthmatics and controls. There was only correlation between serum and sputum IL-10 levels in asthmatics (p < 0.0008, r = 0.73). There was no difference between asthmatic subgroups regarding sputum and serum levels of IL-2 and IL-10. No correlation could be demonstrated between sputum or serum IL-2 and IL-10 levels and clinical severity. CONCLUSIONS: We have demonstrated the presence of detectable concentrations of the IL-2 and IL-10 in serums and induced sputum samples of asthmatics, however, they have no predictive value for asthma since their levels are not increased in asthmatic patients over controls. Moreover, IL-2 level positively correlated with lymphocyte percentage in induced sputum. The results suggest that measurement of IL-2 and IL-10 concentrations in serum and sputum will not be of diagnostic use in asthma and a reflection of the severity of asthmatic airway inflammation.     

Elevated circulating levels of IL-21 and IL-22 define a cytokine signature profile in type 2 autoimmune hepatitis patients

Background and aims. Autoimmune hepatitis (AIH) is a chronic inflammatory condition of the liver in which the immunological mechanisms involved in tissue destruction and/or repair are still unclear. Different pro-inflammatory cytokines have been shown to play a determinant role in AIH pathogenesis. Here, we aim to compare the circulating levels of pro-and anti-inflammatory cytokines such as IL-6, TNF-α, IL-17A/F, IL-21, IL-22, IL-23, and IL-10 in patients with type 2 AIH compared to patients with type 1 AIH and healthy controls (HC). Fourty-six Mexican patients with AIH were recruited in our study. Patients were classified as type 1 or 2 AIH based on immune serological markers. Fourty-four serum samples from healthy individuals were included as controls. Serum cytokine levels were determined by ELISA technique.Results. Compared to healthy controls, serum levels of IL-17F, IL-21, IL-23, IL-10, IL-6, and TNF-α, but not IL-17A and IL-22, were significantly increased in AIH patients. When patients were grouped by aminotransferase activity, a biomarker of active disease, a positive correlation between serum IL-17F and alanine transaminase (rs: 0.4739; P = 0.0009) and aspartate transaminase (rs: 0.4984; P = 0.0004) levels was found. A cytokine signature profile associated with type 2 AIH was characterized by high serum IL-21 (type 1 AIH: 0.66 pg/mL; type 2 AIH: 331.1 pg/mL; P = 0.0042) and IL-22 (type 1 AIH: 0.1 pg/mL; type 2 AIH: 55.26 pg/mL; P = 0.0028) levels.Conclusions. We show for the first time, differential regulation of certain pro-inflammatory cytokines associated with disease progression and AIH type in Mexican patients.     

T-helper Type 1 and 2 Cytokine Levels in Patients with Benign and Malignant Salivary Gland Tumors

Background: Salivary gland tumors are among malignancies that have high recurrence rate. Immune responses in salivary gland tumors have not been well elucidated. T helper type 1 (Th1) and Th2 cytokines have been reported to play a role in the outcome of head and neck cancers. Objective: To evaluate the serum levels of interferon gamma (IFN- γ), as the hallmark of Th1 cytokines, and interleukin-4 (IL-4), as the hallmark of Th2 cytokines, in patients with benign and malignant salivary gland tumors in comparison with healthy controls. Methods: Fifty patients with benign and 14 patients with malignant salivary gland tumors, as well as 23 healthy individuals were recruited. Serum levels of IFN-γ and IL-4 were measured using ELISA method. Nonparametric tests were used for data analysis. Results: Serum levels of IFN-γ and IL-4 were found not to be significantly different in patients compared to the control group (0.68 ± 0.29 vs. 1.03 ± 0.57 pg/ml, p=0.58 for IFN-γ, 4.57 ± 1.57 vs. 4.41 ± 1.31 pg/ml, p=0.28 for IL-4). IFN-γ and IL-4 serum levels were also not significantly different between patients with benign and malignant salivary gland tumors (p=0.54 and p=0.86, respectively). Conclusion: The systemic levels of IL-4 and IFN-γ seem not to be associated with salivary gland tumor in our study. Investigation of other cytokines produced by Th1 and Th2 cells are warranted.

Serum IL-6 and IL-12 levels in breast cancer patients

Previous studies indicated that interleukins 6 & 12 are multifunctional cytokines which regulate of immune response and cancer cell proliferation. We measured serum levels of these cytokines in 40 females with breast cancer and examined their correlation with clinicopathological variables including stages of the disease and estrogen and progesterone receptor expression on tumor cells. Serum levels of IL-6 (mean =111.38 pg/ml) as well as IL-12 (mean=1142.75 pg/ml) were significantly increased in breast cancer patients as compared to controls (mean 1.75 pg/ml &19.90 pg/ml respectively). A statistically significant correlation was found between levels of IL-6 as well as IL-12 and progression of the tumor (P < 0.05). However, no statistical difference was found in serum levels of these cytokines between metastatic and non-metastatic cases. Both cytokines negatively correlated with estrogen and progesterone receptor expression on tumor cells. In conclusion, serum levels of IL-6 and IL-12 are highly elevated in breast cancer patients and correlate with tumor progression. Assays for serum levels of IL-6 and IL-12 can be used as predictive non-invasive tests for tumor progression in breast cancer patients.     

Serum levels of interleukin-10 on admission as a prognostic predictor of human fulminant myocarditis

OBJECTIVES: We assessed the significance of serum cytokine levels in patients with fulminant myocarditis. BACKGROUND: Although many investigations have demonstrated the crucial role of cytokines in the development of myocarditis, it remains uncertain whether serum levels of cytokines enable one to predict the prognosis of human myocarditis, especially concerning cardiogenic shock (CS) requiring a mechanical cardiopulmonary support system (MCSS). METHODS: We studied 22 consecutive patients with fulminant myocarditis and compared them with 15 patients with acute myocardial infarction (AMI) requiring MCSS. The patients with myocarditis were classified into three groups: eight patients with CS requiring MCSS on admission (group 1); six patients who unexpectedly lapsed into CS requiring MCSS more than two days after catecholamine had been initiated (group 2); and eight patients without MCSS (group 3). Furthermore, 14 patients with myocarditis requiring MCSS were divided into a fatal group (n = 5) and a survival group (n = 9). Biochemical markers, including serum cytokine levels and hemodynamic variables on admission, were analyzed. RESULTS: Serum levels of interleukin (IL)-10 and tumor necrosis factor-alpha, but not other cytokines, were significantly higher in myocarditis than in AMI. Only serum levels of IL-10 were significantly higher in group 1 and 2 than in group 3 (49.1 +/- 37.5/20.7 +/- 17.6 pg/ml vs. 2.4 +/- 1.1 pg/ml; p = 0.0008/0.0012). Serum IL-10 levels were also significantly higher in the fatal group than in the survival group with myocarditis (74.0 +/- 27.0 pg/ml vs. 16.4 +/- 8.8 pg/ml; p = 0.003). CONCLUSIONS: Serum IL-10 levels on admission enabled one to predict subsequent CS requiring MCSS and mortality of fulminant myocarditis patients.     

Serum levels of IL-10, IL-6, IL-1ra, and sIL-2R in patients with psoriatic arthritis

Our objective was to evaluate the levels of interleukin-6 (IL-6), soluble receptors of IL-2 (sIL-2R), IL-10, and IL-1 receptor antagonists (IL-1ra) in the serum of patients with psoriatic arthritis (PsA) and to assess the correlation between these levels and parameters of clinical activity of skin and joint disease. In total, 34 patients with PsA and ten healthy volunteers participated in the study. Assessment of joint disease included duration of morning stiffness, number of tender and swollen joints, right and left grip, the presence of inflammatory spinal back pain, and Schober test. Current severity of skin disease was graded according to the psoriasis area and severity index (PASI). Erythrocyte sedimentation rate (ESR) was determined as a marker of disease activity. Serum levels of IL-6, sIL-2R, IL-1ra, and IL-10 were measured by an enzyme immunoassay kit. Significantly higher serum levels of IL-6, sIL-2R, IL-1ra, and IL-10 were found in patients with PsA in comparison with healthy volunteers. A statistically significant correlation was found between levels of sIL-2R and PASI, whereas no association was found with clinical parameters of joint severity. Levels of IL-1ra correlated with the number of tender and swollen joints. No correlation was found between levels of IL-6, IL-10, and clinical parameters of skin and joint severity. In the group of patients with PsA, serum levels of sIL-2R clearly correlated with severity of skin disease, whereas levels of IL-1ra were associated with joint severity.

HCV infection in haemodialysed patients: A role for serum IL-10 and TGF-β1 in liver damage?

BACKGROUND: Hepatitis C virus (HCV) infection is often clinically silent in haemodialysed (HD) patients and their immune response may modulate liver damage in HCV infection. IL-10 and TGF-beta1 could play a role in this setting as, IL-10 down-regulates hepatic fibrosis, while TGF-beta1 is a pro-fibrotic cytokine. AIM: To evaluate the role of IL-10 and TGF-beta1 in HD/HCV+ patients. PATIENTS: 71 HD/HCV+ patients (58 with normal [HD/HCV-N] and 13 with high serum transaminases [HD/HCV-H]), 40 non-uremic patients with chronic hepatitis C (HCV+), 56 HD anti-HCV- patients and 20 healthy volunteers (H). METHODS: IL-10 and TGF-beta1 serum levels were assessed using ELISA tests. Liver histology was assessed by Ishak's score. RESULTS: IL-10 serum levels were significantly higher in HD patients, both HCV+ (3.7+/-0.4 pg/ml; p<0.01) and HCV- (3.8+/-0.8 pg/ml; p<0.05) than in non-uremic HCV patients (2.3+/-0.4 pg/ml). Among the HD/HCV+ patients, IL-10 serum levels were similar in HD/HCV-N and in HD/HCV-H patients. Among the HD/HCV+ patients, IL-10 serum levels were similar in those with moderate histological damage compared to those with mild damage. TGF-beta1 serum levels were significantly lower in HD patients, both HCV+ (4.6+/-0.9 ng/ml) and HCV- (6.0+/-0.9 ng/ml) than in non-uremic HCV+ patients (8.1+/-1.1 ng/ml; p<0.001 and p<0.01, respectively), but similar to the values found in H (5.3+/-0.9 ng/ml; p=n.s.). No correlation was seen between IL-10 and TGF-beta1 serum levels in any of the groups considered. CONCLUSIONS: Patients on haemodialysis treatment to have high levels of IL-10, which remain high even when patients are anti-HCV+, whereas the opposite is true of TGF-beta1. The cytokine pattern observed in HD patients is compatible with the hypothesis explaining the relatively benign evolution of HCV-related liver disease in HD patients, and has a pathophysiological role.

Serum Levels of TNF-α, TNF-αRI,TNF-αRII and IL-12 in Treated Rheumatoid Arthritis Patients

Background: Rheumatoid arthritis (RA) is a chronic multisystem autoimmune disease common in all races and ethnics. Cytokines and cytokines receptors play an important role in RA pathogenesis and clinical presentation. Objective: To investigate the serum levels of TNF-α, TNF-α RI, TNF-α RII and IL-12 in RA patients and healthy control group. Methods: In this study 43 patients fulfilling the revised criteria of American College of Rheumatology (ACR) for RA and 13 healthy cases as a control group were selected for TNF-α, TNF-αRI, TNF-αRII and IL-12 serum level analysis. The patients' age was 42.2 ± 22 and the age of healthy group was 40.1 ± 19.2 years (p=0.1). The pa-tients had an active disease with at least six swollen and ten tender joints. Minimum ESR was 28 mm at first hours of the morning. Early morning stiffness in patients lasted longer than 45 minutes. Results: Our study showed that IL-12 serum level of the pa-tients (91.69 ± 43.07 ρg/ml) and control (61.79 ± 40.08 ρg/ml) group was significantly different (p<0.001). The serum level of TNF-αRI was 2.36 ± 0.77 ng/ml in the patient and 1.73 ± 0.37 ng/ml in the control group (p<0.01). TNF-αRII serum concentration in patients was 8.89 ± 2.3 ng/ml, while that of control group was 7.06±1.30 ng/ml (p=0.03). The serum level of TNF-α in patients was 32.90 ± 19.27 ρg/ml and that of the control group was 24.27± 8.28 ρg/ml (p=0.08) with no significant difference between the two. Conclusions: It is concluded that IL-12, TNF-αRI and TNF- αRII serum con-centrations are more important and better predictive factors than TNF-α in RA course and in the active forms of the disease.     

IL-5、IL-10及FENO三种炎性标记物诊断成人支气管哮喘的临床价值

目的探讨IL-5、IL-10及FENO三种炎性标记物在诊断成人支气管哮喘中的作用及价值,为临床工作提供参考及指导。方法选取2014年10月-2015年12月期间经我院收治的106例成人支气管哮喘患者作为病例组,同时选取同期来我院进行体检的106例健康人群作为对照组,应用酶联免疫吸附法(ELISA)对所有研究对象的血清IL-5、IL-10浓度进行测定,应用FENO测试仪测定其呼出气FENO浓度,比较支气管哮喘组及正常对照组之间的IL-5、IL-10及FENO水平,明确IL-5、IL-10及FENO三种炎性标记物在成人支气管哮喘诊断中的价值。结果病例组及对照组间的IL-5、IL-10及FENO水平存在差异,两组的血清IL-5浓度分别为(23.65±13.86)pg/m L和(11.65±2.79)pg/m L;两组的IL-10浓度分别为(19.78±14.25)pg/m L和(39.21±12.18)pg/m L;两组的FENO水平分别为(63.18±31.62)ug/L和(26.74±18.51)ug/L,两组间差异具有统计学意义(P0.05)。结论 IL-5、IL-10及FENO水平是成人支气管哮喘患者诊断过程中的重要参考指标,对其进行联合检测有利于成人支气管哮喘的早期诊断、预防及个体化治疗的开展。
