Serum Levels Of Interleukin-10 Research Articles

Imbalance of Peripheral Temperature, Sympathovagal, and Cytokine Profile in Long COVID.

A persistent state of inflammation has been reported during the COVID-19 pandemic. This study aimed to assess short-term heart rate variability (HRV), peripheral body temperature, and serum cytokine levels in patients with long COVID. We evaluated 202 patients with long COVID symptoms categorized them according to the duration of their COVID symptoms (≤120 days, n = 81; >120 days, n = 121), in addition to 95 healthy individuals selected as controls. All HRV variables differed significantly between the control group and patients with long COVID in the ≤120 days group (p < 0.05), and participants in the long COVID ≤120 days group had higher temperatures than those in the long COVID >120 days group in all regions analysed (p < 0.05). Cytokine analysis showed higher levels of interleukin 17 (IL-17) and interleukin 2 (IL-2), and lower levels of interleukin 4 (IL-4) (p < 0.05). Our results suggest a reduction in parasympathetic activation during long COVID and an increase in body temperature due to possible endothelial damage caused by the maintenance of elevated levels of inflammatory mediators. Furthermore, high serum levels of IL-17 and IL-2 and low levels of IL-4 appear to constitute a long-term profile of COVID-19 cytokines, and these markers are potential targets for long COVID-treatment and prevention strategies.

The relationship of promoter methylation of calcium voltage-gated channel alpha 1 and interleukin-16 to primary osteoarthritis.

Osteoarthritis is the most prevalent joint disease worldwide and the primary cause of musculoskeletal dysfunction. Epigenetic changes in various genes, particularly methylation, have been implicated as possible underlying causes of primary osteoarthritis. The aim of our study was to investigate the promoter methylation status of the calcium voltage-gated channel alpha 1 subunit G (CACNA1G) and interleukin-16 (IL-16) genes, which are strongly associated with calcium channel activity and antigen presentation, respectively, in primary osteoarthritis patients. Twenty-one patients with primary osteoarthritis and 25 healthy controls were included in our study. The methylation status of CACNA1G and IL-16 genes was analyzed with methylation-specific Polymerase Chain Reaction (PCR), and the serum levels of IL-16 were determined with Enzyme-Linked Immunosorbent Assay (ELISA). The age of the patients was 63.95±8.41 years, and they were 15 females and 6 males. The promoter of the CACNA1G gene was found to be hypermethylated in primary osteoarthritis patients (p<0.001). In contrast, the promoter of the IL-16 gene was found to be hypomethylated compared to the control (p<0.001). The serum levels of IL-16 increased in parallel with the hypomethylated promoter status of IL-16 gene in primary osteoarthritis patients compared to the control (p<0.001). Our study indicates that the methylation status of CACNA1G and IL-16 gene promoters are epigenetically altered in patients with primary osteoarthritis. Moreover, increased serum IL-16 levels in osteoarthritis patients may be associated with hypomethylation of the IL-16 gene promoter.

Associations between IL-17A G/A-rs2275913 and IL 23R A/G-rs11209026 gene polymorphisms and severe coronavirus disease 2019 (COVID-19)

Severe COVID-19 disease was linked to a severe proinflammatory response and cytokine storm interleukin 17 (IL-17) is one of these cytokines, was associated with severe acute lung injury and multiorgan dysfunction. Single nucleotide polymorphisms (SNPs) in genes coding IL-17 can affect level of IL-17 hence its role in diseases. Also, SNPs in IL-23 R which control IL-23 is the main activator of IL-17 production. This study aimed to determine whether the IL-17A (G/A-rs2275913), IL-23R (A/G rs11209026) SNPs and serum levels of IL-17 were related to the risk of severe COVID-19. This case-control study included 120 confirmed COVID-19 patients, divided into two categories according to the severity of the disease and 74 normal subjects as controls. COVID-19 patients were SARS-CoV-2 positive by a reverse transcription-polymerase chain reaction and subjected to full clinical examinations, routine laboratory tests, and radiographic evaluations. The IL-17 levels were assessed using ELISA method, and genotyping of IL-17A (197 A/G; rs2275913) and IL-23R rs11209026 (A/G) was performed by the TaqMan Genotyping Assay. There were no differences in the distribution of IL-17A or IL-23R genotypes between COVID-19 groups and the control group (p=0.93 and p=0.84, respectively). Severe COVID-19 patients had significantly higher IL-17 serum levels than non-severe COVID-19 (p=0.0001). The GG genotypes of IL-17A were significantly higher in severe COVID-19 patients (p=0.004). Multivariate logistic regression analysis revealed that AG, GG genotypes of IL-17 and IL-17A were independent predictors of COVID-19 disease severity (p < 0.0001, p=0.06 and p=0.04, respectively). ROC curve analysis for IL-17, as predictor of severe COVID-19 disease revealed a sensitivity of 87.9% and specificity of 66.1% at a cutoff point of 114 pg/ml with AUC = 0.799. In conclusion, these findings indicated that IL-17 may be considered a marker of severe COVID-19. IL-17A SNPs may have a role in COVID-19 severity. IL-23R SNPs had no role in COVID-19.

Serum Interleukin-37 Levels in Patients with Systemic Sclerosis and its Relation with Clinical Findings

Aim: This study investigates serum interleukin(IL)-37 levels in patients with systemic sclerosis (SS) and assesses its relationship with clinical findings.&#x0D; Methods: This study included 35 patients with SS and 30 healthy control subjects. The demographic and clinical characteristics of the patients, such as the presence of Raynaud’s phenomenon, SS subtype, digital ulcers, gastrointestinal and lung involvement, and disease activity, were recorded. The medications used by the patients were recorded, and Serum IL-37 levels were measured using an enzyme-linked immunosorbent assay. The United Kingdom Functional Scoring system was used to evaluate the functional status of the patients, while the Valentini criteria were used to evaluate disease activity. Skin involvement was evaluated based on the modified Rodnan skin score.&#x0D; Results: Although serum IL-37 levels were found to be lower in patients with SS than in the control group, the difference was not statistically significant (p= 0.078). A negative correlation was identified between serum IL-37 levels and C3 levels in patients with SS (p= 0.046). No significant relationship was found between IL-37 levels and other clinical and laboratory parameters.&#x0D; Conclusion: Unlike in patients with autoimmune disorders, serum IL-37 levels were found to be lower in patients with SS than in the control subjects, and IL-37 demonstrated a negative correlation with C3 levels.

The Effects of a Six-Week Aerobic Exercise on Serum Levels of Klotho, IL-10, IL-1, and Oxidative Stress in Sedentary Young Women

Objectives: Insufficient physical activity is considered one of the leading causes of premature death worldwide. This study, therefore, aimed to investigate the effects of six weeks of moderate-intensity aerobic exercise on serum levels of Klotho, interleukin 10 (IL-10), IL-1, and oxidative stress in young women with a sedentary lifestyle. Materials and Methods: The present study was a semi-experimental study with a control group. Out of all volunteers, 20 young women eligible to participate in the study were selected and divided into the two groups (n=10) of experimental (i.e., six weeks of moderate-intensity aerobic exercise) and control (i.e., no exercise). Members of the experimental group performed an aerobic exercise program including running on a treadmill with an intensity of 55%-70% of their maximum heart rates (220-age). The running plan started with 50% of their maximum heart rates and reached 70% at the end of the six-week exercise program (three sessions per week). Paired t-test and independent t-test were conducted to examine intra-group and inter-group differences. All statistical procedures were performed using the SPSS version26 statistical package (P≤0.05). Results: At the beginning of the study, no significant difference was observed between the groups in terms of the markers. Six-week aerobic training increased Klotho (mean: 540, lower: 141.5, upper: 938.4) and IL-10 (mean: 0.43, lower: -1.56 upper: -0.47) in experimental group in comparison to control group (P=0.001). Six-week aerobic training decreased IL-1 (mean: 0.78, lower: -1.16 upper: -0.39) and H2O2 (mean: 0.41, lower: -0.96, upper: 0.12) in experimental group in comparison to control group (P=0.001). Conclusions: In sum, six-week moderate-intensity aerobic exercise program increased Klotho and IL-10 levels and decreased IL-1 and oxidative stress levels in young women with a sedentary lifestyle. According to these results, the decrease in oxidative stress and IL-1 levels due to exercise caused an increase in Klotho, and an increase in Klotho level, in turn, increased IL-10.

Tenascin-C and Interleukin-17 Up-regulation in Axial Spondyloarthritis Patients

Background: Axial spondyloarthritis (axSpA) is an inflammatory, systemic rheumatic condition that mostly affects the axial skeleton. Tenascin-C (TN-C) is a hexameric glycoprotein of considerable size, upregulated in many inflammatory conditions, while Interleukin-17 (IL-17) a cytokine that plays an important role in SpA symptoms. Objective: to investigate the upregulation between the serum levels of TN-C and IL-17 in Iraqi axSpA patients and the disease characteristics. Patients and Methods: Seventy-four axSpA patients and 28 matched controls were studied. Fifty-four patients received a tumor necrosis factor inhibitor (TNFi) and 20 did not. Serum TN-C and IL-17 concentrations were determined using the ELISA technique. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) was assessed. For statistical tests, Chi Square, Mann Whitney, Independent Samples T, and Pearson's correlation tests are used. Results: Patients mean age was 35.6±0.9 years, 65 males and 9 females, and disease duration was 5.18±0.6 years. 47.4% were smokers, 47% had inflammatory low back pain, and HLA-B27 was present in 91%. BASDAI mean was 6.1±0.4 in non-TNFi and 2.6±0.3 in those on TNFi. The serum TN-C concentration was significantly increased in patients, especially those on non-TNFi (79±9.6 pg/mL) compared to those on TNFi (69.1±3.2 pg/mL) and control (53±3.9 pg/mL) (p=0.003). Serum IL-17 was significantly elevated in those receiving TNFi (877.9±257 pg/mL) compared to non-TNFi (487.2±234 pg/mL) and control (182.4±36.6 pg/mL) (p=0.033). The TN-C significantly correlated with erythrocyte sedimentation rate (r=0.27, p=0.02) and with hemoglobin (Hb) concentration (r=0.26, p=0.02). TN-C and IL-17 were non-significantly related (r=0.14, p=0.2). Conclusions: axSpA Patients demonstrated high levels of serum TN-C, particularly in those not receiving TNFi, and high IL-17 levels in those receiving TNFi, suggesting that there is an association with tissue injury from the disease and stimulation of immunological and resident tissue cells. Patients who had not received TNFi showed significantly higher disease activity than others.

Interleukin-17 and Tumor Necrosis Factor Show a Functional Hierarchy to Regulate the Production of Matrix Metalloproteases by Monocytes from Patients with Psoriasis.

Interleukin-17 (IL-17) and tumor necrosis factor (TNF) regulate tissue remodeling through matrix metalloproteinases (MMPs). It is not yet clear whether these cytokines have a functional hierarchy in psoriasis. Serum levels of TNF (1,403 versus 1,058 pg/mL), IL-17 (1,528 versus 820 pg/mL), MMP-1 (1,999 versus 1,039 pg/mL), and MMP-9 (1,950 versus 1,561 pg/mL) were higher in psoriasis subjects (n = 60) than in control subjects (n = 60). Tissue inhibitor of MMPs (TIMP-1; 1,374 versus 1,218 pg/mL) was lower in psoriasis subjects. Serum IL-17 was correlated with MMP-2 (rs = 0.40) and TIMP-1 (rs = -0.26) levels. Unstimulated production of MMP-1, MMP-2, and MMP-9 by monocytes was higher in psoriasis subjects, whereas TIMP-1 production was lower. TNF stimulation increased all MMPs, whereas TIMP-1 production was unchanged. IL-17 stimulation increased all MMPs, whereas TIMP-1 production was decreased in psoriasis subjects. MMP-9 production was higher in monocytes stimulated with IL-17 compared with TNF. TIMP-1 production was decreased more by IL-17 than by TNF, but only in psoriasis cells. MMP-1/TIMP-1, MMP-2/TIMP-1, and MMP-9/TIMP-1 ratios were higher after IL-17 stimulation (compared with TNF stimulation) in psoriasis subjects; this occurred in controls only for the MMP-2/TIMP-1 ratio. IL-17 has a greater ability than TNF to dysregulate the MMPs/TIMP-1 balance, supporting IL-17 blockade as first-line treatment in cutaneous psoriasis.

The role of interleukin 10 in the development of the schizophrenia deficit syndrome in the light of the disconnection hypothesis

IntroductionOne of the subtypes of schizophrenia is the deficit syndrome (DS). Because of different risk factors, course, response to treatment weak prognosis, researches on this group of patients are important. Etiology of schizophrenia is often hypothesized as the inflammation process. Due to the imbalance of certain cytokines (interleukin-10 (IL-10) -antyinflamation cytokine, among others) changes in the function and structure of central nervous system may occur. That process could stand behind the outbreak of psychotic and deficit symptoms of the illness. Subinflammation can have an impact on the white matter structure. Disturbances in this area can cause impairment of cortical communication and hence, produce psychopathology. One of the structures that seem to have the basis of the deficit syndrome isinferior longitudinal fasciculus (ILF). ILF is a bundle of association fibers with interconnects temporal cortex with ocapital cortex.ObjectivesThe aim of our study was to investigate a relationship between the integrity of ILF and interleukin – 10.Methods39 schizophrenia subjects divided into two groups DS (16) and non-deficyt sydrome (NDS) (23) and 18 healthy controls (HC) participated in the study. A DTI analysis was performed on all study participants. The psychopathology of schizofrenia was assessed using the Positive and Negative Syndrome Scale (PANSS). The ILF analysis was then conducted using fractional anisotropy (FA) and mean diffusivity (MD) parameters. Blood samples were obtained to analyze serum level of IL-10 level.ResultsThe differences in FA value in left ILF between DS and HC group were confirmed. The difference in values of IL-10 between groups were not confirmed. A negative correlation was found between FA values in left ILF and IL-10 (p = 0.033) among DS group.ConclusionsThe imparment of the structure of ILF may be involved in ethiopatogenesis of DS. Moreover, changes in IL-10 levels may be related to the microstructure of ILF bundle.Disclosure of InterestNone Declared

Rheumatoid arthritis and the proinflammatory cytokine IL-17.

Rheumatoid arthritis (RA) is the most common inflammatory joint disease. Various proinflammatory cytokines are involved in the pathogenesis of this chronic disorder. It is characterized by the presence of autoantibodies, such as rheumatoid factor and antibodies against citrullinated peptides. The present study focuses on investigation of possible association between the proinflammatory cytokine interleukin 17 and anti-CCP, anti-MCV, and anti-CarP antibodies seropositivity in RA patients. To assess serum levels of interleukin 17 (IL-17) in patients with rheumatoid arthritis and healthy controls (HC) and to investigate the relationship between IL-17 and anti-cyclic citrullinated protein (anti-CCP) antibodies, antimutated citrullinated vimentin (anti-MCV) antibodies, and anti-carbamylated protein (anti-CarP) antibodies in patients with RA. Forty-seven patients diagnosed with rheumatoid arthritis and 44 healthy controls were included in the study. Serum IL-17 levels were examined in all participants. Anti-CCP, anti-MCV, and anti-CarP antibodies were tested in the group of RA patients. The mean serum level of IL-17 in RA patients was higher (12.8pg/ml) than that in healthy controls (7.9pg/ml), but the difference was not statistically significant (p=0.276). No significant correlation was observed between anti-CCP (+/-) and IL-17 (rs=0.162, p=0.380), and between anti-MCV (+/-) and IL-17 (rs=0.157, p=0.340). A significant positive correlation of moderate value was reported between anti-CarP (+/-) and IL-17 (rs=0.388, p=0.015). The present study demonstrated that the IL-17 serum levels in RA patients were increased compared to healthy controls. No correlation was found between ACPA immunological markers and IL-17 levels in patients with RA. A positive correlation was found between anti-CarP antibodies and IL-17 in the patients' group. The increased level of IL-17 is suggestive of its possible role in the pathogenesis of CarP positive RA patients.

Genetic polymorphisms of interleukin-16 in Egyptian patients with primary knee osteoarthritis

BackgroundThe pro-inflammatory cytokine, interleukin 16 (IL-16), has been shown to be secreted in low levels in knee osteoarthritis (KOA). The aim of the study was to examine the relationship between IL-16 polymorphisms and the risk of KOA in the Egyptian population, as well as the clinical and radiographic severity of KOA.ResultsIL16 rs11556218 thymidine triphosphate (T) T G (guanosine triphosphate), GG, TG + GG genotypes, and G allele (odd ratio (OR) = 0.315; 95% confidence interval (CI) = 0.191–0.518; P < 0.001; OR = 0.363; 95% CI = 0.162–0.815, P = 0.014; OR = 0.323; 95% CI = 0.202–0.519, P < 0.001; OR = 0.480; 95% CI = 0.338–0.683, P < 0.001 respectively); rs4778889 cytidine triphosphate (C) T,CC, TC + CC genotypes, and C allele (OR = 0.519, 95% CI = 0.319–0.844, P = 0.008; OR = 0.309, 95% CI = 0.105–0.916, P = 0.034; OR = 0.485, 95% CI = 0.304–0.775, P = 0.002; OR = 0.537, 95% CI = 0.365–0.791, P = 0.001 respectively); and rs4072111 CT, TT, CT + TT genotypes, and T allele (OR = 0.537, 95% CI = 0.323–0.893, P = 0.017, OR = 0.316, 95% CI = 0.096–0.843, P = 0.049, OR = 0.502, 95% CI = 0.309–0.816, P = 0.005; OR = 0.534, 95% CI = 0.353–0.809, P = 0.004 respectively) were associated with a decreased KOA risk, and they were significantly associated with decreased the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and the Kellgren-Lawrence (K/L) scores.Neither IL-16 serum levels nor IL-16 polymorphisms were associated with the susceptibility to KOA. Low KOA risk was associated with the haplotypes GTC and TCT.ConclusionThere was no correlation between serum IL-16 levels and KOA susceptibility or IL-16 polymorphisms. GTC and TCT haplotypes were associated with low KOA risk. The variant alleles rs11556218GG, TG + GG; rs4778889 CC, TC + CC; and rs4072111 TT, CT + TT were associated with a reduced risk of KOA.

Assessment of Selected Immunological Parameters in Dairy Cows with Naturally Occurring Mycotoxicosis before and after the Application of a Mycotoxin Deactivator.

Mycotoxins in dairy cows can cause many non-specific symptoms often resulting from immune system overreaction. The study assessed the concentration of selected cytokines and acute phase proteins (APP) in cows with natural mycotoxicosis before and after using a mycotoxin neutraliser. The cytokines were tumour necrosis factor alpha (TNF-α), interleukin 6 (IL-6) and interleukin 10 (IL-10), and the APP were serum amyloid A (SAA) and haptoglobin (Hp). The research was carried out on an experimental group (Exp) of 10 herdmate Holstein-Friesian cows with mycotoxicosis. The control group (Con) was 10 healthy cows of the same breed from a different herd. Cows in the Exp group were administered the mycotoxin deactivator Mycofix for three months. Blood was drawn from Exp cows once before administering Mycofix and a second time after three months of its use. Blood was also drawn from Con cows at the same times. Serum levels of TNF-α, IL-6, IL-10, SAA and Hp were assessed using ELISA. The concentrations of all cytokines and Hp in Exp cows were higher before treatment (P < 0.001) than those in Con cows. After three months of administering Mycofix, the concentrations of TNF-α and IL-6 were significantly lower than their pre-treatment levels (P < 0.001). The concentrations of IL-6, IL-10, and Hp were still significantly higher than those in the Con group (P < 0.001). In cows with mycotoxicosis, simultaneous stimulation of antagonistic processes was noted: a pro-inflammatory process in the upregulation of TNF-α and IL-6, and an anti-inflammatory one in the upregulation of IL-10. Despite the absorbent's use and the resolution of clinical symptoms in Exp cows, high levels of IL-10 and Hp and IL-6 were maintained. Assessment of the level of cytokines and APP appears to be a useful and precise tool for the evaluation and application of the appropriate dose of the mycotoxin absorbent or the evaluation of its effectiveness.

Vitamin D and Interleukin-17: Are These Serum Biomarkers Useful in Non-Segmental Vitiligo? A Case Control Study from Central India.

Non-segmental vitiligo (NSV) is an autoimmune disorder due to the destruction of melanocytes, where cytokines like interleukin 17 (IL-17) and biomolecules like vitamin D play a theoretical role in pathogenesis. Previous studies in this regard yielded inconsistent results. This study aimed to compare the serum levels of IL-17 and vitamin D between NSV patients and healthy controls and to know the association of these biomarkers with disease activity and extent. This was a case-control study including adult patients with NSV and age and gender-matched healthy controls. Cases and controls with conditions likely to alter the serum levels of IL-17 and vitamin D were excluded. Serum levels of IL-17 were estimated by ELISA and vitamin D levels by chemiluminescence assay. 42 adult patients of NSV and 42 age and sex-matched healthy controls were recruited over a period of eighteen months. The mean value of serum vitamin D levels in the control group was 19.053 ± 5.340 ng/ml, whereas in the case group, it was 17.336 ± 6.931 ng/ml (P > 0.05). The mean value of serum IL-17 levels in the control group was 199.824 ± 51.244 pg/ml and 213.566 ± 69.018 pg/ml in the case group (P > 0.05). These molecules did not show any association with the disease activity and extent. In contrast to the previous studies, we could not establish the role of IL-17 in the pathogenesis of vitiligo. Furthermore, we could not find any association between vitamin D and vitiligo in our study, even though there is an inconsistent association between the two in the available literature.

The effects of Rhus coriaria L. (sumac) and Cinnamomum zeylanicum L. bark on serum cytokine levels in rat mammary carcinogenesis.

The purpose of this study was to assess the potential effects of Rhus coriaria L. (sumac) and of Cinnamomum zeylanicum L. bark on the selected serum cytokines as possible serum tumor markers - interleukin-6 (IL-6), interleukin-10 (IL-10), and tumor necrosis factor-α (TNF-α) in the rat model of mammary carcinogenesis. R. coriaria and C. zeylanicum bark were used as the chemopreventive-therapeutic agents taken by rats in the powder form in the diet at two different concentrations during the entire period of two experiments carried out separately: lower concentration 1 g/kg - 0.1% and higher concentration 10 g/kg - 1%. The serum levels of cytokines of IL-6, IL-10, and TNF-α were determined using an enzyme-linked immunosorbent assay. In the first experiment treated with R. coriaria, a significant decrease in serum levels of IL-6 and TNF-α was present at higher concentrations compared to the chemoprevention-free control group. R. coriaria at lower concentrations non-significantly reduced the serum levels of IL-6 and TNF-α when compared to controls. A significant decrease in serum levels of TNF-α was present at higher concentrations compared to lower concentrations. The significant effect of R. coriaria on the serum levels of IL-10 was not observed. In the second experiment treated with C. zeylanicum bark, a significant decrease in serum levels of IL-6 was observed in lower and higher concentrations compared to the chemoprevention-free control group. C. zeylanicum bark non-significantly reduced the serum levels of TNF-α and had no effect on the serum levels of IL-10. In conclusion, R. coriaria and C. zeylanicum bark demonstrated significant anti-inflammatory effects by analyzing the selected serum cytokine levels in the rat breast carcinoma model. Observed anti-inflammatory effects of both plant-natural substances were associated with their anticancer activities in rats.

Contradictory Effect of Lymphocyte Therapy and Prednisolone Therapy on CD3+CD8+CD56+ Natural Killer T Population in Women with Recurrent Spontaneous Abortion.

Natural killer T (NKT) cells are influential immune cells in pregnancy failures, including recurrent spontaneous abortion (RSA). Different approaches are used for these disorders due to their effects on maternal immunomodulation. In the present study, we compared the effects of two typical immunotherapies (lymphocyte immunotherapy [LIT] and low-dose prednisolone) on CD3+CD56+CD16+ and CD3+CD56+CD8+ cells as two distinct subsets of NKT cells in Women with RSA. This study was a comparative cohort study conducted from 2021 to 2022. One hundred and five women with RSA were distributed into three treatment groups randomly. Fifty women in the group of low-dose prednisolone therapy, fifty women in the LIT group and five women without any treatment as the control group were included in the study. NK and NKT cell subsets were assessed using flow cytometry. Furthermore, the concentration of interferon-gamma (IFN-γ), transforming growth factor-beta (TGF-β) and interleukin-10 (IL-10) was measured quantitatively using the enzyme-linked immunosorbent assay technique. Normality and comparisons between study groups were performed by non-parametric unpaired Mann-Whitney, Kruskal-Wallis rank sum test, and one-way ANOVA. The percentage of CD56dim NK cells was increased after prednisolone therapy, while this population significantly decreased in the LIT group. In contrast to the LIT group, the administration of prednisolone increased CD3+CD8+CD56+ NKT cells (P < 0.0001), which is helpful for pregnancy. The effect of the investigated treatment approaches on the population of peripheral CD3+CD56+CD16+ NKT cells of women with RSA was not adequately significant. The same situation was also observed regarding the serum level of IFN-γ. However, a significant decrease in serum levels of IL-10 and TGF-β was observed after prednisolone therapy. The lower capability of LIT in changing the population of NKT cells compared to prednisolone therapy may be due to its mechanism of action, which is related to the production of blocking antibodies. These treatment approaches had different effects on NKT cells, indicating that NKT cell population and function can be affected using LIT and prednisolone therapy distinctly. In addition, prednisolone therapy and LIT in women with normal serum levels of IFN-γ have no harmful effects in changing the production of this critical cytokine.

Analysis of Interleukin-17, Interleukin-23, neopterin and Nesfatin-1 levels in the sera of Hashimoto patients.

Hashimoto's thyroiditis (HT) is an autoimmune disorder affecting the thyroid gland and may present as goiter or atrophic thyroiditis that may result in various metabolic and inflammatory disorders. The aim of this study is to determine the changes in serum levels of interleukin-17 (IL-17), IL-23, neopterin, and nesfatin-1 parameters in HT patients and to evaluate the possible relationship among these parameters. 90 HT patients and 30 healthy individuals were included in this study. Demographic data of the patients included in the study were recorded and detailed physical examinations were performed. IL-17, IL-23, neopterin, and nesfatin-1 levels were measured in the serum samples of the participants by the ELISA method.

Serum interleukin-21 level in patients with severe adverse cutaneous drug reactions and correlation with disease severity

IntroductionInterleukin-21 (IL-21) is accepted to play a pathogenic part in development of unfavorable cutaneous medicate responses. Adverse cutaneous drug reactions create a wide run of clinical signs such as pruritus, maculopapular ejections, urticaria, angioedema, fixed drug eruption, erythema multiforme, vesiculobullous responses (e.g. Stevens–Johnson syndrome and toxic epidermal necrolysis), and exfoliative dermatitis.Patients and methodsTwenty patients (drug-eruption group) and 14 healthy controls (control group) were recruited from Assiut University Hospitals' Dermatology Department and Outpatient Clinic. Data were collected in the period from October 2017 to December 2018. Patients were assessed clinically by percentage of surface area of the body involvement (body surface area %) and score of toxic epidermal necrolysis. At presentation and after 1 month of treatment, blood samples were taken to evaluate serum IL-21 levels using an enzyme-linked immunosorbent assay.ResultsInside the study, the cruel serum IL-21 level was considerably greater than in the control group, in drug-eruption group was 575.58 ± 94.67 ng/dl, and in the control group was 128.00 ± 73.94 ng/dl with P value of 0.000. The drug-eruption group had a significantly higher serum level of IL-21 before treatment than after treatment with P value of 0.000. Additionally, there was a critical relationship between IL-21 levels in the blood and the severity of the condition. Before and after therapy, there was a significant positive association between blood IL-21 levels and the proportion of body surface area involvement.ConclusionIL-21 levels in the blood were significantly higher in EM and SJS/TEN patients, suggesting that it may have a role in the etiology of EM and SJS/TEN and it could be employed as a marker for the severity of SJS/TEN and patient prognosis in the future.

Biomonitoring the skeletal muscle metabolic dysfunction in knee osteoarthritis in older adults: Is Jumpstart Nutrition® Supplementation effective?

This study aimedto investigate the efficacy of Jumpstart Nutrition® dietary supplement (JNDS) for enhancing the skeletal muscle metabolism and function of older adults with knee osteoarthritis (KOA) by evaluating the biomarkers of aberrant levels of serum tumor necrosis factor-alpha (TNF-α), interleukin-10 (IL-10), C-reactive protein (CRP), creatine kinase-muscle (CK-MM), and aldolase-A (Aldo-A). This twelve-week registry included 54 patients treated with JNDS mainly comprised of calcium, phosphorus, vitamin-K2, coenzyme-Q10, boswellic acid, and curcumin mixed with soy and whey protein (experimental group) and 51 patients treated with symptomatic slow-acting drugs for osteoarthritis (SYSADOA) (control group) for KOA confirmed with radiological images. At week 0 and week 12 for both the groups evaluated, the non-fasting serum levels of TNF-α, IL-10, CRP, CK-MM, and Aldo-A by using appropriate kits. At week-twelve, the respective values of area under the ROC curves of the studied biomarkers for pooled experimental cohorts were 0.928, 0.907, 0.908, 0.927, and 0.988 having the significance of accuracy (R-square):66.28%, 47.25%, 70.39%, 65.13%, and 68.00%, indicating a satisfactory treatment policy, their mean± SD, and risk ratio, all exhibited highly significant differences (p<0.0001) and KOA-gradation was upgraded between≥2 and ≥3 from≥4 as per the Kellgren-Lawrence scale compared to the control. Fewer patients had to use emergency medications (p<0.05). Results suggest that JNDS may be effectively used to strengthen the skeletal muscle metabolismand function of elderly patients with KOA confirmed with the stabilization of studied biomarkers as an alternative to the treatment of SYSAD correlated with ROC curves and the Kellgren-Lawrence scale.

Predictive Value of Serum YKL-40, Interleukin-37, and Cancer Antigen 125 Panel in Noninvasive Staging of Endometriosis

Abstract Background: The diagnosis of advanced endometriosis remains challenging with considerable limitations in the diagnosis of retroperitoneal and deep infiltrating lesions. Thus, a well-defined panel of inexpensive, noninvasive inflammatory biomarkers could be a crucial tool for appropriate staging for women with suspected endometriosis. The aim of this work is to explore the potential use of serum YKL-40, interleukin-37 (IL-37), and cancer antigen 125 (CA125) for noninvasive staging of endometriosis patients for proper intervention and most optimal management of the condition. Methods: This study was conducted on 90 women, who had undergone laparoscopic or laparotomy surgery due to suspected pelvic endometriosis. Blood samples for serum YKL-40, IL-37, and CA125 levels assay were taken from all participants at admission for laparoscopy or laparotomy. After histopathological confirmation of the diagnosis, the selected cases were immunostained for YKL-40, IL-37, and CA125. Results: YKL-40, IL-37, and CA125 serum levels were significantly elevated in patients with endometriosis than healthy controls. Moreover, the association between the serum level and immunoexpression and grading of endometriosis. A triple combination panel of serum YKL-40, IL-37, and CA125 was found to have the best sensitivity and specificity (96.67% and 100.0%, respectively) compared to any single serum marker alone or double combination panel in predicting the severity of endometriosis. Conclusions: A triple combination panel of serum YKL-40, IL-37, and CA125 could be used in the future for predicting endometriosis stage, providing a practical reference for making better-informed decisions on the best treatment plan.

Cytokine-mediated immunoregulatory activity of Lactobacillus species in a carrageenan-induced acute inflammatory model.

Using paw edema acute inflammatory model induced by carrageenan (1%) in Wistar rats, the immunoregulatory action of Lactobacillus sp., isolated from two locally fermented food products in Nigeria: Nunu (a yogurt-like milk product) and Ogi (guinea corn slurry), was investigated. The rats were distributed into seven groups (A-G). Rats in group A did not receive any therapy or carrageenan inflammation, whereas those in group B received a carrageenan injection only. Groups C-F were orally administered with lactic acid bacteria (LAB) strains (5 × 107 CFU/ml), whereas group G received diclofenac sodium (150 mg/kg body weight) following the administration of carrageenan. At regular intervals, paw thickness (mm) was measured. Microscopy was used to count the number of leukocytes; myeloperoxidase (MPO) activity was used to measure the neutrophil accumulation in the paw tissue; and rat serum samples were subjected to ELISA to identify cytokine assays for C-reactive protein (CR-P), interleukin-10 (IL-10), and transforming growth factor-β (TGF-β). All of the LAB-treated groups showed a statistically significant decrease in paw thickness, and their neutrophil and monocyte infiltration was significantly affected. Compared with the control groups, oral administration with LAB significantly suppressed the MPO activity. Lactobacillus fermentum NBRC showed the most significant upregulation of serum levels of IL-10 and TGF-β though serum levels of CR-P were downregulated. Lactobacillus pentosus increased the production of TGF-β, with no significant effect on the production of IL-10. This study presents the role of Lactobacillus sp. in regulating inflammation by modifying the production of anti-inflammatory cytokines IL-10 and TGF-β.

Relationships of Low Serum Levels of Interleukin-10 With Poststroke Anxiety and Cognitive Impairment in Patients With Clinical Acute Stroke.

The relationships among interleukin (IL)-10 levels, anxiety, and cognitive status after stroke remain controversial. We aimed to determine the associations of serum IL-10 levels with poststroke anxiety (PSA) and poststroke cognitive impairment (PSCI). We recruited 350 patients with stroke, of whom only 151 completed a 1-month follow-up assessment. The Mini Mental State Examination (MMSE) and Hamilton Anxiety Scale (HAMA) were used to assess the cognitive status and anxiety, respectively. Serum IL-10 levels were measured within 24 hours of admission. IL-10 levels were significantly lower in the PSA group than in the non-PSA group, and they were negatively associated with HAMA scores (r=-0.371, p<0.001). After adjusting for all potential confounders, IL-10 levels remained an independent predictor of PSA (odds ratio=0.471, 95% confidence interval=0.237-0.936, p=0.032). IL-10 levels were strongly correlated with behavior during interviews, psychic anxiety, and somatic anxiety. Patients without PSCI had higher IL-10 levels were higher in non-PSCI patients than in PSCI patients, and they were positively associated with MMSE scores in the bivariate correlation analysis (r=0.169, p=0.038), and also with memory capacity, naming ability, and copying capacity. However, IL-10 did not predict PSCI in the univariable or multivariable logistic regression. Low IL-10 levels were associated with increased risks of PSA and PSCI at a 1-month follow-up after stroke. Serum IL-10 levels may therefore be helpful in predicting PSA.
