The Effects of In Ovo Injection of Synbiotics on the Early Growth Performance and Intestinal Health of Chicks.

In this study, the effects of synbiotic inclusion at the intra-amniotic stage in layer chicks were evaluated with different parameters, such as performance, immunological function, intestinal development, and cecal microflora content. A total of 1,200 eggs with fertile embryos were allocated into four treatment groups. For every treatment, five replicates were used, and 60 eggs were included in each replicate. The following four treatment groups were established: the non-injected group, 0.9% physiological saline injection (saline) group, 1 × 106 CFU/egg Lactobacillus plantarum injection (probiotic) group, and 1 × 106 CFU/egg L. plantarum + 2 mg/egg Astragalus polysaccharide injection (synbiotic) group. In ovo injection was carried out at 18.5 days of incubation. The results showed that in ovo injection of probiotics or synbiotics did not affect the hatching or growth performance of the chicks but significantly increased their feed intake (FI), body weight (BW), and the feed conversion ratio (FCR). Additionally, in ovo injection of synbiotics enhanced the levels of serum interleukin-2 (IL-2), interferon-γ (IFN-γ), and secretory immunoglobulin A (SIgA) in intestinal lavage fluid and the histomorphological development of the small intestine. Our results also indicated that intra-amniotic synbiotic injection significantly increased Lactobacillus and Bifidobacterium colonization while decreasing the relative abundance of Escherichia coli in the chicken cecum (P < 0.05). In summary, in ovo injection of synbiotics had positive impacts on the performance, immunological function, gut development, and microbiota of growing chicks.

TA allele of rs2070673 in the CYP2E1 gene is associated with lobular inflammation and nonalcoholic steatohepatitis in patients with biopsy-proven nonalcoholic fatty liver disease.

Cytochrome P450 2E1 (CYP2E1) plays a role in lipid metabolism, and by increasing hepatic oxidative stress and inflammation, the upregulation of CYP2E1 is involved in development of nonalcoholic steatohepatitis (NASH). We aimed to explore the relationship between CYP2E1-333A>T (rs2070673) and the histological severity of nonalcoholic fatty liver disease (NAFLD). We studied 438 patients with biopsy-proven NAFLD. NASH was defined as NAFLD Activity Score≥5 with existence of steatosis, ballooning, and lobular inflammation. CYP2E1-333A>T (rs2070673) was genotyped by matrix-assisted laser desorption ionization-time of flight mass spectrometry. Serum cytokines related to inflammation were measured by the Bio-plex 200 system to investigate possible mediating factors involved in the process. The TA genotype of rs2070673 had a higher prevalence of moderate/severe lobular inflammation (27.6% vs 20.3% vs 13.3%, P<0.01) and NASH (55.7% vs 42.4% vs 40.5%, P<0.01) compared with the AA and TT genotypes, respectively. In multivariable regression modeling, the heterozygote state TA was associated with moderate/severe lobular inflammation (adjusted odds ratio: 2.31, 95% confidence interval 1.41-3.78, P<0.01) or NASH (adjusted odds ratio: 1.82, 95% confidence interval 1.22-2.69, P<0.01), independently of age, sex, common metabolic risk factors, and presence of liver fibrosis. Compared with no-NASH, NASH patients had significantly higher levels of serum interleukin-1 receptor antagonist, interleukin-18, and interferon-inducible protein-10 (IP-10), whereas only IP-10 was increased with the rs2070673 TA variant (P=0.01). Mediation analysis showed that IP-10 was responsible for ~60% of the association between the rs2070672 and NASH. The TA allele of rs2070673 is strongly associated with lobular inflammation and NASH, and this effect appears to be largely mediated by serum IP-10 levels.

In Vitro and In Vivo IFN-γ and IL-10 Measurement in Experimental Brucella abortus Biotype 1 Infection in Sprague-Dawley Rats.

The immune response to Brucella abortus mainly depends on antigen-specific T cell activation, CD4+ and CD8+ T cells, and Brucella-specific humoral response. Protective immune response against Brucella infection has not been performed in the Sprague-Dawley (SD) rat model. We measured bacterial kinetics in addition to in vivo and in vitro interferon gamma (IFN-γ) and interleukin-10 (IL-10) production against crude Brucella protein in the SD rats at different days of postinfection with B. abortus biotype 1 by indirect enzyme-linked immunosorbent assay. Forty SD rats were inoculated intraperitoneally with 0.1 mL sterile injectable pyrogen-free solution containing 1 × 1010 colony-forming units/mL of B. abortus biotype 1 obtained from cattle in Korea. Four rats were used as uninfected control. Serum IFN-γ level at 3 and 7 days postinfection were significantly higher (p > 0.001) compared with the IL-10 level. On the contrary, serum IL-10 levels were observed significantly higher at 21 and 28 days postinfection compared with the serum IFN-γ levels (p < 0.001). The production of IFN-γ by spleen cells was significantly higher at 7 and 14 days postinfection compared with IL-10 (p < 0.001). On the contrary, IL-10 productions were found to be significantly higher at 21, 28, 35, and 42 days postinfection compared with IFN-γ (p < 0.001). The presence of B. abortus in blood was marked till 5 weeks of infection, throughout the experiment in case of spleen, and no bacteria were isolated from the kidney and liver at 6 weeks postinfection. The in vivo and in vitro IFN-γ and IL-10 measurement in our study reported that B. abortus infection in rats primarily educe T helper (Th)1-dominant immune response in acute infection accompanied by Th2-dominant immune response in chronic infection.

Comparison of safety, effectiveness and serum inflammatory factor indexes of Saccharomyces boulardii versus Bifidobacterium triple viable in treating children with chronic diarrhea: a randomized trial.

BackgroundDiarrhea is common in children under 5 years of age and is an important public health problem in China. CD is the main obstacle to the growth and development of children, which brings a great burden to individuals, families and society. The objective of this work is to study the efficacy and safety of Saccharomyces boulardii versus Bifidobacterium triple viable in the treatment of CD in children.MethodsFrom October 2018 to October 2020, a total of 161 children aged 2–8 years hospitalized with CD were randomly allocated into S. boulardii group, Bifidobacterium triple viable group and control group. After 14 days of treatment, the curative effect and recovery time of the three groups were evaluated. The levels of serum interleukin (IL)-6, IL-7 and tumor necrosis factor-alpha (TNF-α) before and after the treatment were valuated and compared among the three groups, together with clinical efficacy and safety.ResultsThe recovery time of the Bifidobacterium triple viable group was significantly shorter than that of S. boulardii group (P<0.05). The marked effective rate and total effective rate of the Bifidobacterium triple viable group were significantly higher than those of the control group (P<0.05); the total effective rate of the S. boulardii group was significantly higher than that of the control group (P<0.05). The improvement in the levels of IL-6, IL-7 and TNF-α in the Bifidobacterium triple viable group was greater than that in the control group; the improvement in IL-6 and IL-7 levels in the Bifidobacterium triple viable group was greater than that in the S. boulardii group; the improvement in IL-6 and IL-7 levels in the S. boulardii group was greater than that in the control group, and the differences were statistically significant (P<0.05)ConclusionsThe efficacy of Bifidobacterium triple viable and S. boulardii in the treatment of children with CD was better than that of conventional treatment. The treatment effect for Bifidobacterium triple viable was more significant, and it was proved to be safe, to shorten the course of disease, and have clinical relevance.Trial registrationChinese Clinical Trial Registry ChiCTR2100046444.

Evaluation of IL-10, IFN-γ, and thiol-disulfide homeostasis in patients with drug-resistant epilepsy.

This study compared dynamic thiol-disulfide homeostasis (an oxidative stress marker), anti-inflammatory interleukin-10 (IL-10) levels, and proinflammatory interferon gamma (IFN-γ) levels in drug-resistant epilepsy patients with those in patients with well-controlled epilepsy and healthy controls. This prospective cross-sectional study enrolled 89 people: 27 with drug-resistant epilepsy, 30 with well-controlled epilepsy, and 32 healthy controls matched in demographic characteristics. The mean serum IL-10 levels were significantly lower and the mean serum IFN-γ levels significantly higher in the drug-resistant epilepsy patients compared to the well-controlled epilepsy and healthy control groups. The mean serum native thiol (SH) and total thiol (TT) levels were significantly lower, and the disulfide (SS) levels were significantly higher in the drug-resistant group than in the other two groups. The significant differences in thiol-disulfide homeostasis and IL-10 and IFN-γ levels in the drug-resistant epilepsy group suggest that these markers indicate a poor prognosis in epilepsy.

Associations between P53, Transforming Growth Factor Beta-1, and Interleukin-10 Serum Levels with Advanced Liver Disease and Hepatitis B Virus Infection

Background. Hepatitis B infection can lead to advanced liver disease (ALD) which causes serious health problems. Several factors that are thought to play a role in advanced liver disease are P53, Transforming Growth Factor-β1 (TGF-β1), and Interleukin-10 (IL-10). Therefore, this study aimed to determine the association between P53, TGF-β1, and IL-10 serum levels with ALD.Methods. We collected 68 sera from patients with HBV infection. P53, TGF-β1, and IL-10 serum levels were measured by ELISA. We also detected SNPs from P53 and TGF-b1 genes to determines their associations.Results and Conclusions: In this study, we obtained 41.18% CH patients and 58.82% ALD patients. Male patients outnumbered female in all groups. There was a significant relationship between serum P53 and TGF-b1 levels with ALD (p = 0.03 and 0.01, respectively), but not serum IL-10 levels. However, there was no significant relationship between SNP gene P53 and serum P53 levels nor between SNP gene TGF-b1 and serum TGF-b1 levels (p = 0.73 and 0.23, respectively).Both P53 and TGF-b1 serum leveles can act as biomarkers of prognosis and target therapy for ALD patients.

Effects of Temperature and Volume of Intraoperative Normal Saline Irrigation on Postoperative Pain, Swelling, and Serum Markers of Inflammation in Patients After Elective, Arthroscopic, Single-Bundle Surgical Reconstruction of the Anterior Cruciate Ligament: A Retrospective, Single-Center Study.

BackgroundArthroscopic single-bundle surgical reconstruction of the anterior cruciate ligament (ACL) is often performed electively after 3 weeks of mobilization therapy. The present single-center retrospective study aimed to investigate the effects of temperature and volume of intraoperative normal saline irrigation on postoperative pain and swelling and on serum markers of inflammation following elective, arthroscopic, single-bundle surgical reconstruction of the ACL.Material/MethodsClinical data from 716 patients with non-acute ACL injuries who met the criteria between March 2015 and May 2020 were retrospectively analyzed. The patients were broken into 5 groups, depending on the volume or temperature of intraoperative irrigation with normal saline. At specific times after surgery, pain, knee swelling, and skin temperature were assessed. Postoperative levels of serum C-reactive protein (CRP), interleukin (IL)-1, IL-6, and IL-10 also were measured.ResultsVisual analog scale (VAS) scores for pain, rates of swelling, and skin temperature differed significantly among the 5 groups at all postoperative time points (P<0.001). The VAS scores(P=0.322) and ratings for swelling (P=0.245), and skin temperature (P=0.093) were not significantly different among the volume groups. There were no significant differences in the VAS scores (P=0.055), swelling ratings (P=0.570), or skin temperatures (P=0.321) among the groups that received irrigation with normal saline at different temperatures. There were no significant differences in postoperative serum levels of CRP, IL-1, IL-6, or IL-10 among the groups (P>0.05).ConclusionsIrrigation with different volumes and temperatures of normal saline did not have a significant effect on postoperative pain, swelling, or serum markers of inflammation.

Effect of Tiaodu Jieyu acupuncture on cancer-related depression: a randomized controlled trial

To observe the effect of Tiaodu Jieyu acupuncture combined with sertraline hydrochloride and sertraline hydrochloride alone on cancer-related depression (CRD), and to explore its action mechanism. A total of 120 patients with CRD were randomly divided into an observation group and a control group, 60 cases in each group. Based on the routine treatment of oncology, the patients in the control group were treated with sertraline hydrochloride tablets, 50 mg per time, once a day, and the patients in the observation group were additionally treated with Tiaodu Jieyu acupuncture at Zhongwan (CV 12), Baihui (GV 20), Shenting (GV 24), Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20), Shenmen (HT 7), Taichong (LR 3), Taixi (KI 3), 20 to 40 min per time, once a day, 5 times a week. Both the treatments were given for 6 weeks. The self-rating depression scale (SDS) score, Hamilton depression scale (HAMD) score before treatment and after 2-week, 4-week and 6-week treatment as well as the levels of serum interleukin (IL)-2, IL-4, IL-10, interferon gamma (IFN-γ) and transforming growth factor β (TGF-β) before and after treatment were observed in the two groups. Compared before treatment, the SDS scores and HAMD scores in the two groups were reduced after 2-week, 4-week and 6-week treatment (P<0.05), and SDS scores and HAMD scores in the observation group were lower than those in the control group (P<0.05). Compared before treatment, the serum levels of IL-4, IL-10 and TGF-β in the two groups after treatment were reduced (P<0.05), and those in the observation group were lower than the control group (P<0.05). Compared before treatment, the serum levels of IL-2 and IFN-γ in the two groups after treatment were increased (P<0.05), and those in the observation group were higher than the control group (P<0.05). Tiaodu Jieyu acupuncture combined with sertraline hydrochloride tablets could effectively relieve the depression state in patients with CRD, and the curative effect is better than sertraline hydrochloride tablets alone. The mechanism may be related to regulating the expression of immune-related cytokines.

Effects of dietary carboxymethyl pachyman on oxidative stress and inflammation in weaned piglets challenged with diquat

This study aimed to examine the effects of carboxymethyl pachyman (CMP) on oxidative stress and inflammation in piglets using a diquat-challenge model. Forty weaning piglets were assigned into four treatment groups in a 2 × 2 factorial arrangement in a completely randomized design with the effects of CMP supplementation and diquat challenge. Treatments consisted of a basal diet with saline injection, a basal diet supplemented with CMP at 0.01 % with saline injection, a basal diet with diquat challenge, and a basal diet supplemented with CMP at 0.01 % with diquat challenge. Carboxymethyl pachyman was mixed with the basal diet. On day 21 after initiation of the treatment, the piglets were intraperitoneally injected with diquat at 10 mg/kg body weight or the same volume of sterilized saline. The experiment was carried out for 28 days. The results showed that dietary CMP supplementation under diquat challenge increased (P < 0.05) serum catalase activity in piglets. Furthermore, CMP supplementation relieved the diquat-induced inflammation reflected by decreased (P < 0.05) levels of serum interleukin (IL)-6, IL-8, IL-12 and transforming growth factor-β1, and increased (P < 0.05) the level of serum IL-4 in piglets. In conclusion, dietary CMP supplementation reduced inflammation in diquat-challenged piglets.

CORRELATION OF INTERLEUKIN-23 SERUM LEVELS IN MEN WITH ACNE VULGARIS: A PRELIMINARY STUDY

Background: Acne vulgaris (AV) is an inflammatory condition of pilosebaceous unit that is common in adolescents and young adults. The pathogenesis of AV is multifactorial, one of which is inflammation. Interleukin-23 (IL-23) has an important role in the activity of T helper 17 (Th17) cells that produce IL-17 in chronic inflammation.Objective: To determine the correlation between serum IL-23 levels and AV severity in men.Methods: This is an analytical observational preliminary study with a cross-sectional design involving 15 male subjects with AV who were divided into groups of AV severity based on Lehmann’s criteria. The subjects were examined for serum IL-23 levels. Data were analyzed using Spearman’s Rho non-parametric correlation test to determine the correlation between variables.Results: Mean IL-23 serum levels in men with AV was 111,05 ± 115,27 pg/ml, with mild AV was 210,57 ± 122,038 pg/ml, moderate AV was 103,65 ± 91,15 pg/ml and severe AV was 18,94 ± 15,76 pg/ml. There is a significant correlation between IL-23 serum levels and AV severity in men. (p = 0,001). Serum IL-23 levels decreased with increasing AV severity (r = -0,756).Conclusion: There is a strong negative correlation between IL-23 serum levels and AV severity in men.

MicroRNA-146a Expression and Serum Interleukin-17 Level as potential biomarkers for Rheumatoid Arthritis

Small non-coding RNAs are microRNAs (miRNAs) that can play a role in controlling various immune functions. MicroRNA-146a (miRNA-146a) is regarded as an essential element in posttranscriptional gene expression regulator, indicating a possible function in autoimmune diseases. Aim: The aim of the research was to evaluate the expression of miR-146a and Interleukin-17 serum levels as potential markers for rheumatoid arthritis (RA) diagnosis and to investigate its association with the activity of the disease. Methods: This research comprised 60 subjects divided into 30 RA patients and 30 healthy individuals. The rate of erythrocyte sedimentation rate (ESR), anti-cyclic-citrullinated peptide (anti-CCP) antibodies rheumatoid factor (RF), C-reactive protein (CRP) and serum IL-17 level were estimated. Using reverse transcriptase real time polymerase chain reaction quantitative, the relative quantification of miR-146a expression was determined. Results: There are highly pronounced statistical variations was observed between patients and healthy controls, with relative expression of miR-146a, (ESR), CRP, IL-17 and (anti-CC). There are also extremely important statistical differences (p < 0.001) between the various patient subgroups with respect to miR-146a relative expression. IL-17 level in the RA group was higher than in the control group. Positive associations were noticed between the levels of IL-17, ESR, CRP, (anti-CCP) and miR-146a. Conclusion: This study showed that even the expression of miR-146a was highly significant in RA patients, the level of expression was associated with the activity of the disease. Also, the increase in serum IL-17 in patients with RA compared with healthy controls played an important role in the diagnosis of the inflammatory and destructive characteristics of RA.

The Association of Serum IL-10 Levels with the Disease Activity in Systemic-Onset Juvenile Idiopathic Arthritis Patients

Objectives Interleukin-10 (IL-10) has been suggested as a biomarker of disease activity in patients with adult-onset Still's disease (AOSD). In this study, we evaluated the serum IL-10 levels and investigated its clinical relevance in systemic-onset juvenile idiopathic arthritis (SoJIA). Methods IL-10 levels were determined in 21 patients diagnosed with SoJIA and 35 patients with fever diseases which were suspected as SoJIA, and IL-10 levels were compared between SoJIA patients with regard to disease activity, disease courses, and other biomarkers. Results Patients with SoJIA had significantly higher levels of IL-10 compared to patients with other febrile diseases. The serum levels of IL-10 were significantly higher in active SoJIA compared to inactive and positively correlated with known disease activity markers such as erythrocyte sedimentation rate (ESR), C-reactive protein level (CRP), ferritin (FER), and IL-6 levels. Moreover, the levels of IL-10 at diagnosis were significantly higher in SoJIA patients with a nonmonocyclic pattern than in patients with a monocyclic pattern. Compared to CRP, ESR, FER, and IL-6, IL-10 levels were superior in predicting monocyclic patients from nonmonocyclic patients. Conclusion Compared to other febrile diseases, SoJIA patients have markedly higher levels of IL-10 which may assist with diagnosis. And a clear association of serum IL-10 levels with disease activity and disease courses in SoJIA was found. These results suggest that serum IL-10 might be a reliable clinical marker in SoJIA.

Role of interleukin-2 and interleukin-18 in newly diagnosed type 2 diabetes mellitus.

The study aimed to compare the levels of anti-inflammatory interleukin-2 (IL-2) and proinflammatory interleukin-18 (IL-18) among newly diagnosed type 2 diabetes mellitus (T2DM) and nondiabetic volunteers, to predict their roles as markers in the diagnosis of newly diagnosed T2DM. In the study, 60 subjects were enrolled (30 T2DM cases and 30 non-diabetic controls). Biochemical parameters such as fasting plasma glucose (FBS), glycated haemoglobin (HbA1c), high sensitivity C-reactive protein (hs-CRP) and lipid profile were estimated in auto-analyser. Serum IL-2 and IL-18 levels were assessed by enzyme-linked immune sorbent assay (ELISA). Significant differences were observed in the levels of interleukins among study groups. The median (95% confidence interval) of IL-2 in cases and controls were 8.55 (6.07-47.23) and 45.87 (12.81-145.4) (p=0.02). The median (95% CI) of IL-18 on the other hand in cases and controls were 691.6 (580.3-872.6) and 511.1 (452.6-557.5) (p=0.0014). Our study is the first to correlate IL-2 and IL-18 in newly diagnosed T2DM patients. Findings from this study highlight the anti-inflammatory role of IL-2 and proinflammatory role of IL-18 in T2DM. ROC analysis helped predict their role as markers in T2DM diagnosis.

A pilot study evaluating GSK1070806 inhibition of interleukin-18 in renal transplant delayed graft function

IntroductionDelayed graft function (DGF) following renal transplantation is a manifestation of acute kidney injury (AKI) leading to poor long-term outcome. Current treatments have limited effectiveness in preventing DGF. Interleukin-18 (IL18), a biomarker of AKI, induces interferon-γ expression and immune activation. GSK1070806, an anti-IL18 monoclonal antibody, neutralizes activated (mature) IL18 released from damaged cells following inflammasome activation. This phase IIa, single-arm trial assessed the effect of a single dose of GSK1070806 on DGF occurrence post donation after circulatory death (DCD) kidney transplantation.MethodsThe 3 mg/kg intravenous dose was selected based on prior studies and physiologically based pharmacokinetic (PBPK) modeling, indicating the high likelihood of a rapid and high level of IL18 target engagement when administered prior to kidney allograft reperfusion. Utilization of a Bayesian sequential design with a background standard-of-care DGF rate of 50% based on literature, and confirmed via extensive registry data analyses, enabled a statistical efficacy assessment with a minimal sample size. The primary endpoint was DGF frequency, defined as dialysis requirement ≤7 days post transplantation (except for hyperkalemia). Secondary endpoints included safety, pharmacokinetics and pharmacodynamic biomarkers.ResultsGSK1070806 administration was associated with IL18-GSK1070806 complex detection and increased total serum IL18 levels due to IL18 half-life prolongation induced by GSK1070806 binding. Interferon-γ−induced chemokine levels declined or remained unchanged in most patients. Although the study was concluded prior to the Bayesian-defined stopping point, 4/7 enrolled patients (57%) had DGF, exceeding the 50% standard-of-care rate, and an additional two patients, although not reaching the protocol-defined DGF definition, demonstrated poor graft function. Six of seven patients experienced serious adverse events (SAEs), including two treatment-related SAEs.ConclusionOverall, using a Bayesian design and extensive PBPK dose modeling with only a small sample size, it was deemed unlikely that GSK1070806 would be efficacious in preventing DGF in the enrolled DCD transplant population.Trial registrationNCT02723786.

Interleukin-10 (IL-10) 1082 promoter polymorphisms and plasma IL-10 levels in patients with bacterial sepsis.

Background. Interleukin-10 (IL-10) is a multifunctional cytokine which has been seen to play a relevant role in the pathogenesis of sepsis. We examined the association between a single nucleotide polymorphism (SNP) in IL-10-1082G/A in patients with sepsis in Cali city.Methods. A total of 100 patients with sepsis and 50 control subjects were enrolled in this study. Blood samples were collected from all patients in EDTA containing tubes. IL-10-1082G/A gene promoter polymorphism was analyzed by Sequence Specific Polymerase Chain Reaction (SS-PCR), while levels of serum IL-10 were measured by Enzyme Linked Immunoassay Assay (ELISA) in patients with sepsis and healthy controls.Results. AA homozygous genotype was found more frequently in patients (32%), compared with controls (18%). AA homozygous patients showed an increased risk of developing infection by Gram-negative bacteria (OR = 2,875; 95% CI = 1.162-7.113; p = 0.020), and significantly high plasma levels of IL-10 (OR = 4.800, 95% CI 1.652-13.944; p = 0.002). AA homozygous patients high plasma IL-10 levels have greater risk of developing sepsis (63.6%; OR = 4,894; 95% CI: 1,337-17,909; p = 0.002). In this group, Afro-Colombian individuals were overrepresented among the sepsis patients with high plasma IL-10 levels (OR = 1.661; 95% CI: 1.408-1.959; p = 0.036).Conclusion. Our study concluded that AA genotype of IL-10-1082G/A polymorphism is a risk factor for high IL-10 production and development of sepsis by Gram negative bacteria, especially in Afro-Colombian patients.

Correlation between Serum Interleukin-17 level and Serum Reactive Oxygen Species levels among Children experiencing Otitis Media with Effusion.

Introduction The detection of inflammatory mediators in the serum of children with have otitis media with effusion (OME) and their correspondence with clinical considerations may enable the use of a modern nonsurgical curative treatment for OME. Objective To determine the relation between interleukin-17 (IL-17) serum level and reactive oxygen species (ROS) serum levels in children suffering from OME and to disclose if any variation occurs in the level of IL-17 Will affect the ROS and antioxidant equilibrium in the serum, which indicates the entire body's reaction to OME. Methods The present study was a case-control study. A total of 24 children experienced OME, and 24 healthy controls were recruited. All participants in the study were subjected to a systematic clinical investigation including otoscopic, audiometric, and tympanometric examination. Also, venous blood samples were collected from all children to determine the levels of IL-17 and ROS.Results The mean ± standard deviation (SD) age ranges of the patients and the control group were 6.8 ± 2.7 and 6.2 ± 3.4 years, respectively. A stylistically significant difference in the levels of serum nitric oxide (NO), catalase (CT), myeloperoxidase (MPO), and malondialdehyde (MDA) ( p < 0.05) was detected between OME and control patients. No significant difference was found in serum levels of superoxide dismutase (SOD) and glutathione peroxidase (GPX) between OME and control patients. The serum levels of MDA, NO, and MPO positively correlated with the serum levels of IL-17 in OME patients. Conclusion In the present study, there is a reasonable role of the IL-17 pathway in OME pathogenesis through an increase in ROS levels.

Interleukin-7/Interferon Axis Drives T Cell and Salivary Gland Epithelial Cell Interactions in Sjögren's Syndrome.

Primary Sjögren's syndrome (SS) is characterized by a lymphocytic infiltration of salivary glands (SGs) and the presence of an interferon (IFN) signature. SG epithelial cells (SGECs) play an active role in primary SS pathophysiology. We undertook this study to examine the interactions between SGECs and T cells in primary SS and the role of the interleukin-7 (IL-7)/IFN axis. Primary cultured SGECs from control subjects and patients with primary SS were stimulated with poly(I-C), IFNα, or IFNγ. T cells were sorted from blood and stimulated with IL-7. CD25 expression was assessed by flow cytometry. SG explants were cultured for 4 days with anti-IL-7 receptor (IL-7R) antagonist antibody (OSE-127), and transcriptomic analysis was performed using the NanoString platform. Serum IL-7 level was increased in patients with primary SS compared to controls and was associated with B cell biomarkers. IL7R expression was decreased in T cells from patients with primary SS compared to controls. SGECs stimulated with poly(I-C), IFNα, or IFNγ secreted IL-7. IL-7 stimulation increased the activation of T cells, as well as IFNγ secretion. Transcriptomic analysis of SG explants showed a correlation between IL7 and IFN expression. Finally, explants cultured with anti-IL-7R antibody showed decreased IFN-stimulated gene expression. These results suggest the presence of an IL-7/IFNγ amplification loop involving SGECs and T cells in primary SS. IL-7 was secreted by SGECs stimulated with type I or type II IFN and, in turn, activated T cells that secrete type II IFN. An anti-IL-7R antibody decreased the IFN signature in T cells in primary SS and could be of therapeutic interest.

MicroRNA profiling in Chinese children with Henoch-Schonlein purpura and association between selected microRNAs and inflammatory biomarkers.

This study aimed to profile the microRNA levels in Chinese Henoch-Schonlein purpura (HSP) children and to explore their association with inflammatory factors and T helper 17 (Th17)/regulatory T (Treg). Forty-five HSP children and 27 healthy controls were enrolled in this study, and microRNA levels were profiled with a microRNA microarray. The levels of selected microRNAs were determined by quantitative real-time PCR, and the levels of serum IgA, interleukin-6, interleukin-10 and interleukin-17A were detected by enzyme-linked immunosorbent assay. Additionally, Th17 and Treg cells were analysed by flow cytometry. There were 9 up-regulated and 27 down-regulated microRNAs in the PBMCs of Chinese HSP children. Among them, miR-1-3p, miR-19b-1-5p and miR-29b-1-5p were up-regulated, while miR-483-5p and miR-1246 were down-regulated. Additionally, these selected microRNAs could differentiate HSP patients from healthy controls. Interestingly, miR-29b-1-5p was correlated with IgA, miR-19b-1-5p, miR-483-5p and miR-1246 were correlated with interleukin-6, while miR-1-3p and miR-1246 were correlated with Th17/Treg. This study reveals that the altered microRNAs could differentiate HSP from the healthy, and were associated with inflammatory factors or Th17/Treg. It is indicated that alteration in these microRNAs may contribute to the HSP pathogenesis and may become therapeutic targets or diagnostic biomarkers for HSP.

Glutathione transferase Omega 1 confers protection against azoxymethane-induced colorectal tumour formation.

Inflammatory bowel disease (IBD) is characterized by multiple alterations in cytokine expression and is a risk factor for colon cancer. The Omega class glutathione transferase GSTO1-1 regulates the release of the pro-inflammatory cytokines interleukin 1β (IL-1β) and interleukin 18 (IL-18) by deglutathionylating NEK7 in the NLRP3 inflammasome. When treated with azoxymethane and dextran sodium sulphate (AOM/DSS) as a model of IBD, Gsto1-/- mice were highly sensitive to colitis and showed a significant increase in the size and number of colon tumours compared with wild-type (WT) mice. Gsto1-/- mice treated with AOM/DSS had significantly lower serum IL-1β and IL-18 levels as well as significantly decreased interferon (IFN)-γ, decreased pSTAT1 and increased pSTAT3 levels in the distal colon compared with similarly treated WT mice. Histologically, AOM/DSS treated Gsto1-/- mice showed increased active chronic inflammation with macrophage infiltration, epithelial dysplasia and invasive adenocarcinoma compared with AOM/DSS treated WT mice. Thus, this study shows that GSTO1-1 regulates IL-1β and IL-18 activation and protects against colorectal cancer formation in the AOM/DSS model of IBD. The data suggest that while GSTO1-1 is a new target for the regulation of the NLRP3 inflammasome-associated cytokines IL-1β and IL-18 by small molecule inhibitors, there is a possibility that anti-inflammatory drugs targeting these cytokines may potentiate colon cancer in some situations.
