Cytokine Genetic Polymorphism of Interleukin-4 and Risk of Asthma in Some Iraqi Patients

Abstract Background: Asthma, a chronic inflammatory respiratory disorder, is influenced by genetic and environmental factors. Allergic asthma is becoming more common because of higher levels of air pollution. Interleukin-4 (IL-4) plays an important role in allergic inflammation and causes the expression of vascular cell adhesion molecule-1. Objective: The present study aims to shed light on the association between cytokine genetic polymorphisms and asthma in Iraqi patients, and to determine their impact on the risk of disease, under the scope of the following: (1) IL-4 cytokines, in terms of their serum level. (2) Assessment of the polymorphisms in the promoter regions of the IL-4, genes in asthma disease patients was carried out, and then their impact on the profile of investigated cytokines was evaluated. Such a collective evaluation may aid in a better understanding of etiopathogenesis in the asthma disease. Materials and Methods: A case-control study was conducted that included 100 participants divided into a patient group (n = 50) with bronchial asthma and a healthy group as a control (n = 50) without asthma. Blood specimens were collected from participants at Marjan Hospital, Babylon Governorate. Serum levels of IL-4 were estimated by an enzyme-linked immunosorbent assay (ELISA) kit. IL4-590 gene polymorphism was detected using amplification refractory mutation system polymerase chain reaction (PCR) with specific primer sequences. Results: The mean concentrations of serum IL-4 were significantly higher in patients having asthma compared to the healthy group (149.84 vs. 53.50, P < 0.0001). In terms of allele and genotype frequencies, the TT genotype was shown to be less common in asthma group compared to controls (4% vs. 22%), whereas the CT genotype was more common in asthma patients (34% vs. 16%). The CC genotype was similar between the two groups. The T allele was more frequent in healthy (39%) compared to asthmatic group (12%), whereas the C allele frequency was higher in asthma patients (61%) compared to controls (88%). Conclusion: This study suggests that gene polymorphism of IL4-590 is associated with risk of developing asthma. Asthma patients have elevated levels of IL-4 and a lower frequency of the TT genotype, indicating an increased likelihood of developing asthma when carrying the T allele and TT genotype. Conversely, the C allele may have a protective influence against asthma development.

Profile of Interleukin-6 and Tumor Necrosis Factor-α in Hospitalized COVID-19 Patients

Abstract Background: In 2019’s December, the new COVID-19 coronavirus induced severe lower respiratory tract syndrome in Wuhan, China. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ultimately became responsible for the life-threatening pandemic. The magnitude and outcome of COVID-19 may be related to the overproduction of pro-inflammatory cytokine called “cytokine storm.” Cytokine production besides the age of patients, and comorbidities, all influence the length and severity of SARS-CoV-2. Objectives: This research was performed to investigate how these factors affect patients who have severe COVID-19 in a sample of Iraqi patients. Materials and Methods: A total of 82 participants were enrolled in this work, confirmed hospitalized COVID-19 patients (n = 60) and healthy control (n = 22) from both sexes of age range 20‐67 years. Tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) levels in the serum of COVID-19 patients and HC have been evaluated using an ELISA. Results: According to our findings, sera from COVID-19 patients had considerably higher levels of IL-6 and TNF-α than those of the control group. Furthermore, most infections were among women (63%), followed by men (37%), the higher number of patients were within 50‐59 years, while the lowest number of patients was found in the group 20‐29 years. Most COVID-19 patients appeared to be overweight and obese. Additionally, those who have diabetes mellitus are also at risk of severe COVID-19. Conclusion: Serum levels of TNF-α and IL-6 were higher in patients than in the control group, suggesting that they could be used as indicators of the severity of COVID-19 illness. Also, their combined detection provided highest specificity and sensitivity for early prediction of COVID-19 severity, which has significant clinical values.

Serum interleukin 18 level in kidney diseases and age.

Interleukin-18 (IL-18), also known as interferon-gamma inducing factor is a protein which in humans is encoded by the IL18 gene, it is a member of the IL 1 family and has a molecular weight of 18 kDa. Innate and adaptive immunity can be regulated by IL-18, and disorders involving its dysregulation might result in inflammatory or autoimmune conditions. To distinguish between acute kidney injury (AKI) and chronic renal failure (CRF), this research investigates the utility of IL-18 as a novel biomarker and examines how age affects its level. Three hundred participants were included and divided into three groups using the following methodology. Group I consisted of 100 control subjects who were split up by age and gender. Group II consisted of 100 AKI patients who were divided into two groups and subgroups based on age and gender. Group III, which consisted of 100 CRF (hemodialyzed patients), was divided into two groups and subgroups, as patients with acute renal injury and previously healthy people. Patients' blood was drawn to conduct a laboratory investigation blood urea, serum creatinine, sodium, potassium, pH, GFR and PCO2. Patients with CRF had higher serum levels of IL-18 than patients with AKI, regardless of gender, and both groups of patients had levels of IL-18 that rise with age. IL-18 is a reliable indicator for the differentiation between AKI and CRF patients receiving hemodialysis and its level correlates with age independent with gender.

Correlation of circulating fibroblast growth factor 21 levels with inflammatory factors and the degree of coronary artery stenosis in patients with acute myocardial infarction

BackgroundFibroblast growth factor 21 (FGF21) is a secreted protein that plays an important role in atherosclerosis and pathological cardiac remodeling. However, the correlation between FGF21 and the degree of coronary artery stenosis and its potential role in acute myocardial infarction (AMI) remain unclear. We examined whether changes in FGF21 levels in AMI correlate with the degree of coronary artery stenosis and the levels of inflammatory factors, and preliminarily investigated the effects of FGF21 on inflammatory factor levels and myocardial injury in rats with AMI. MethodsSerum levels of FGF21 and inflammatory factors in the AMI group and control group were measured, and the correlation between FGF21 and clinical indicators and inflammatory factors was analyzed. The effects of FGF21 on cardiac function and inflammatory response were evaluated through echocardiography and measurement of inflammatory factors. ResultsMultivariate logistic regression analysis showed that neutrophil percentage (NEUT%, odds ratio [OR]: 1.232; 95 % confidence interval [CI]: 1.028–1.477; p = 0.024) and FGF21 levels (OR: 2.063; 95 % CI: 1.187–3.586; p = 0.01) had independent effects on AMI. Spearman's rank correlation test showed that FGF21 levels were positively correlated with leukocyte count, NEUT%, neutrophil count, neutrophil to lymphocyte ratio, C-reactive protein, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), monocyte chemotactic protein-1 (MCP-1) and Gensini scores (p < 0.01), but negatively correlated with lymphocyte count (p < 0.01). FGF21 levels in myocardial tissues and serum levels of FGF21, IL-6, TNF-a, and MCP-1 were significantly higher in AMI rats than in the sham-operated group (p < 0.01). After overexpression of FGF21, serum levels of IL-6, TNF-a, and MCP-1 in rats were significantly decreased (p < 0.01), and cardiac function improved significantly. ConclusionsFGF21 levels were independently associated with AMI and may be related to the severity of coronary artery stenosis. Overexpression of FGF21 reduced serum inflammatory factor levels and improved cardiac function in AMI rats.

Assessment and prognostic significance of a serum cytokine panel in diffuse large B‑cell lymphoma.

The objective of the present study was to assess the levels of circulating cytokines in patients with diffuse large B-cell lymphoma (DLBCL), and to examine the associations between the cytokine levels, clinicopathological manifestations and patient prognosis. The study enrolled 49 patients with DLBCL, 11 patients with chronic lymphocytic leukemia/small lymphocytic lymphoma and 67 healthy controls from Zhejiang Provincial People's Hospital (Hangzhou, China) between January 2017 and January 2020. The serum levels of interleukin (IL)-2, IL-4, IL-6, IL-10, IL-17, tumor necrosis factor (TNF)-α and interferon (IFN)-γ were measured using flow cytometry. The IL-6, IL-10 and IFN-γ levels were significantly raised in patients with DLBCL compared with those in the healthy controls (P<0.05). The levels of IL-10 were significantly higher in patients with raised levels of circulating lactate dehydrogenase (P<0.05), while increases in both IL-6 and IL-10 were associated with raised C-reactive protein (CRP) levels, with IL-6 levels positively associated with those of serum CRP (P<0.01; r=0.66). Additionally, International Prognostic Index (IPI) risk stratification of patients with DLBCL was strongly associated with circulating IL-6 and IL-10 levels. Raised IL-6, IL-10 and TNF-α levels were linked with worse short-term treatment efficacies (P<0.05). Moreover, the accuracy of the model predicting short-term treatment response in patients with DLBCL, obtained using the support vector machine algorithm, was 81.63%. It was also found that raised serum IL-6 and IL-10 levels, together with reduced levels of IL-17, were associated with survival of <1 year in patients with DLBCL (P<0.05), although no significant link was found between cytokine levels and long-term overall survival. In conclusion, the serum levels of IL-6, IL-10, IL-17, TNF-α and IFN-γ can potentially serve as biological indicators of DLBCL tumor immune status, and combined application with the IPI score can be a robust prognostic indicator in patients with DLBCL.

A Systematic Review of the Novel Targeted Immunobiological Medications in Rheumatoid Arthritis: Efficacy, Safety, and Innovation

Introduction: Over the last half-century, the treatment and management of autoimmune rheumatic diseases have progressively improved, particularly with the contribution of immunobiological or biological therapies known as disease-modifying antirheumatic drugs. Although these agents have been generally efficient in the management of rheumatoid arthritis (RA), some patients experience limited efficacy and non-responsiveness to treatment. In addition, they may cause adverse clinical effects, further aggravating the disease. Objectives: Despite advancements in biological therapies, significant clinical needs persist. This review aims to discuss novel treatments, guiding future guidelines and drug discoveries for rheumatoid arthritis. Methods: This review follows the 2020 PRISMA statement, utilising PubMed and Google Scholar for literature search and emphasizing recent meta-analyses on the safety and efficacy of targeted immunobiological medications. Results: Small molecule inhibitors, whether utilised independently or in conjunction with Methotrexate, have been shown to contribute to effective disease management and have the potential for better adherence to the American College of Rheumatology criteria. Tocilizumab therapy demonstrates a significant reduction in disease activity and improves rates of disease remission when combined with Methotrexate. Investigations of mesenchymal stromal cell therapies have had promising outcomes, improving both cartilage quality (as evaluated by Macroscopic Cartilage Repair Assessment) and joint tenderness and swelling in clinical joint counts. Intra-articular administration of tolerogenic dendritic cells has displayed a capacity to alleviate pain, as measured by Visual Analog Scale scores, and enhance the Disease Activity Score across 28 joints. Resveratrol capsules supplemented with allopathic therapy show potential in reducing TNF-α and interleukin-6 serum levels. Conclusion: More investigations and their analysis will improve patient outcomes and reduce adverse effects and the costs involved in developing and obtaining immunobiological drugs. Moreover, assessing the safety and efficacy of anti-RA properties of the bioactive compounds could offer less toxic and more cost-effective natural treatment options.

Interpersonal violence exposure and inflammation during adolescence and young adulthood

Exposure to violence increases young peoples’ risk of developing mental and physical health problems. Chronic stress-related upregulation of innate immune system activity and the development of low-grade inflammation may partially underlie this health risk. However, much of the previous research has been limited to cross-sectional studies utilizing between-person analytic designs, susceptible to confounding by unmeasured factors. In this six-wave panel study of N=157 female adolescents and young adults, we tested within-person associations between interpersonal violence exposure and multiple measures of inflammatory activity. Ex vivo culture studies suggested that participants’ immune cells were more reactive to microbial stimulation and less sensitive to inhibition by glucocorticoids after violence. Numbers of circulating monocyte cells increased after violence, but serum levels of interleukin-6 and c-reactive protein did not. Findings from this within-person analysis suggest that violence exposure up-regulates innate immune system activity during adolescence and young adulthood in ways that may increase mental and physical health risk.

A Matched Case-Control Study of the Serum Level and Gene Expression of IL-6 and IL-12 in Patients with Schizophrenia Spectrum Disorder: An Azeri Acute Phase/Recent-Onset Psychosis Survey (ARAS) Study

Background: The causes of schizophrenia spectrum disorders are believed to be multifactorial, with both genetic and environmental factors, as well as gene-environment interactions, influencing the course of this disorder. Research suggests that immunological factors may play a role in the development of psychotic disorders. Objectives: The aim of this study is to evaluate and compare the serum levels of interleukin-6 (IL-6) and interleukin-12 (IL-12), as well as the expression levels of IL-6 and IL-12 genes, between an Iranian Azeri population of patients with first-episode psychosis and healthy controls. Methods: Forty patients who had recently experienced first-episode non-affective psychosis were allocated to the patient group. Forty healthy volunteers, matched for age and gender, were also recruited as controls. The study was conducted in 2020 in Tabriz, Iran. Peripheral blood samples were collected (using the Ficoll-Paque process) and assessed to determine the expression levels of IL-6 and IL-12 mRNA (using real-time Polymerase Chain Reaction-PCR- system), as well as the serum levels of IL-6 and IL-12 (with a sandwich ELISA kit). GraphPad Prism Version 6.0 was used for all statistical analyses. Results: Each group consisted of 40 participants in this study. Patients had significantly higher levels of IL-6 mRNA expression compared to the healthy controls (P &lt; 0.0001), while no significant difference was found between the two groups in terms of IL-12 mRNA expression (P = 0.5697). A similar pattern was reported for the serum levels of IL-6 (P &lt; 0.0001) and IL-12 (P = 0.0777). The area under the curve (AUC), which indicates the accuracy of the predictive model, was 0.9669 for the level of IL-6 mRNA expression (P &lt; 0.0001). This Area (AUC) was 0.9584 for the serum concentration of IL-6 (P &lt; 0.0001). The levels of IL-6 or IL-12 were not correlated with the severity of symptoms, gender, or age of the patients. Conclusions: The expression level of IL-6 mRNA and the serum concentration of IL-6 were altered in patients with first-episode non-affective psychosis. This finding supports the role of inflammatory pathways in the pathogenesis of psychosis. According to our results, measurement of the circulating level of IL-6 may be useful in distinguishing patients with first-episode psychosis from healthy individuals.

Ophiocephalus striatus Extract Supplementation Decreases Serum IL-6 Levels in Older People with Sarcopenia-A Single-Center Experience.

Sarcopenia, a condition characterized by muscle loss and decreased function in older adults, is a growing public health concern. This study aimed to investigate the effects of Ophiocephalus striatus extract on insulin-like growth factor-1 serum, interleukin-6 serum levels, and sarcopenia-related parameters in older adults with sarcopenia. This double-blind randomized controlled trial included 80 older adults with sarcopenia. Participants were randomly assigned to receive Ophiocephalus striatus extract or a placebo for two weeks. The IGF-1 serum and IL-6 serum levels were assessed as primary outcomes. The Ophiocephalus striatus extract intervention resulted in a significant reduction in serum IL-6 levels. Although the IGF-1 levels did not show significant changes, there was an increase for the intervention group. This study demonstrated that a 2-week intervention with Ophiocephalus striatus extract positively impacted the serum IL-6 levels in older adults with sarcopenia. While the IGF-1 levels did not change significantly in this short intervention period, the observed improvements in IGF-1, calf circumference, muscle mass, and muscle strength are promising. The findings suggest that Ophiocephalus striatus extract may offer a valuable intervention for managing sarcopenia, particularly in regions with abundant Ophiocephalus striatus production, such as South Sumatera. This study was registered with trial number NCT05869383.

Elevated expression of Toll-like receptor 7 and its correlation with clinical features in patients with primary Sjögren’s syndrome

BackgroundThe labial salivary glands (LSGs) are important for the diagnosis, evaluation of therapeutic efficacy, and genetic analyses of primary Sjögren’s syndrome (pSS). In autoimmune diseases, the recognition of self nucleic acids and viral RNA and DNA through endogenous Toll-like receptor(TLR) triggers the production of type I IFN and pro-inflammatory cytokines, leading to the occurrence and progression of the disease. Here, we detected the expression of TLR7 in LSGs and analyse its correlation with clinical features and serum cytokines in pSS patients.MethodsLSGs and serum samples were obtained from 56 pSS patients and 19 non-SS patients (non-pSS patients). The expression of TLR7 in the LSGs was evaluated with immunohistochemistry. The serum levels of interferon-α (IFN-α) and interleukin-6 (IL-6) were quantified by ELISA. Laboratory parameters were measured by clinical standard laboratory techniques.ResultsTLR7-positive cells in pSS were localized in the ductal epithelial cells and lymphocytes of LSGs. The expression of TLR7 was upregulated in pSS patients compared with controls. Patients with anti-Ro52 antibody positivity showed higher TLR7 levels than those who were negative but not those with anti-Ro60 and anti-SSB. TLR7 levels were positively associated with the levels of IgG, IgA, ANA, IL-6, IFN-α and serum globulin but were not associated with IgM, C3, C4, or rheumatoid factor (RF) in serum.ConclusionTLR7 may be involved in the inflammatory response and the production of antibodies in pSS and plays an important role in local and systemic pSS manifestations. This research showed that TLR7 is involved in pSS pathogenesis.

Investigation of IL-6 serum level in COVID-19 patients with positive COVID-19 IgG/IgM antibody titers to check inflammation and disease progression

ObjectiveThe SARS-CoV-2, the cause of coronavirus disease 2019 (COVID-19), leads to severe pathogenicity and high mortality among different communities around the world. Therefore, it is important to understand the mechanisms of virus pathogenesis and the immune system's response to prevent the further spread of this virus. This study was aimed to evaluate the relationship between the serum level of interleukin 6 and positive IgG and IgM antibody levels in patients with COVID-19 to investigate inflammation and disease progression. Methods & MaterialsIn this study, 10 ml of EDTA blood samples were taken from 414 COVID-19 patients. Then, the plasma was separated and the levels of IgM and IgG antibodies and interleukin 6 cytokine were evaluated by ELISA and chemiluminescence methods, respectively. All data were analyzed by SPSS 22 and GraphPad prism 9 software at the significance level of P < 0.05. ResultsThe results of this study showed that there was no significant difference in the expression of IgM and IgG antibodies between men and women. Also, a significant increase in the mean expression of IL-6 was observed only in the high concentration range (100−〉1000 pg/ml) in men compared to women (P < 0.001). In addition, in the female population, all three concentration ranges (negative, medium, and high) of IL-6 have the highest correlation with high titers (>10 U/ml) of IgM and IgG antibodies. While, in men, all three concentration ranges of IL-6 had the highest correlation with > 10 U/ml IgM antibody titers, but in the case of IgG, the highest correlation between different concentrations of IL-6 was observed with the negative or moderate titers of this antibody and there was an inverse relationship with the high titers of IgG (>10 U/ml). ConclusionAs a result, the relationship between different serum levels of cytokine IL-6 with different titers of IgM and IgG antibodies was observed in both male and female populations. In general, it can be concluded that the correlation between different concentrations of IL-6 with different IgM titers was similar in both men and women, but in the case of different IgG titers, this correlation was higher in women than men.

A Study of how the Serum Levels of Inflammatory Markers Correlate with Hemoglobin Oxygen Saturation Percentage and the Type of Respiratory Support Received by Covid-19 Patients Hospitalized in Intensive Care Units

Aim This study aimed to shed light on how serum levels of interleukin-6 (IL-6), lactate dehydrogenase (LDH), and C-reactive protein (CRP) correlate with hemoglobin oxygen saturation percentage (SpO2) and the type of respiratory support received among COVID-19 patients hospitalized in COVID-19 intensive care units. Background The clinical care of patients who suffer from COVID-19 requires knowledge of laboratory findings and the way these findings are linked with the type of respiratory support. Methods This descriptive-analytical study was conducted using data from the clinical records of 31 patients hospitalized in the intensive care unit at 22nd-Bahman Hospital in Khaf, Eastern Iran, during the first half of 2021. The study utilized a checklist developed by the researcher for data collection. The data were analyzed with Kolmogorov-Smirnov, independent t, one-way analysis of variance, and Tukey's post hoc statistical tests in the SPSS-22 statistical package. The significance level was established at p &lt;0.05. Results The mean CRP, LDH, and serum levels of IL-6 were significantly higher in COVID-19 patients with SpO2 &lt;93 than in patients with SpO2 ≥93 (p &lt;0.05). Patients receiving intubation and non-invasive respiratory support exhibited significantly greater serum levels of IL-6, CRP, and LDH than patients receiving other respiratory support (p &lt;0.05). The mean CRP, serum levels of IL-6, and LDH were significantly lower among survivors than those who died (p &lt;0.01). Conclusion Understanding the relationship between the serum levels of IL-6, CRP, LDH, and SPO2 and the type of respiratory support can help predict the management of acute respiratory patients, but this decision-making method based on serum levels should be further investigated. and to be compared with the current methods of management of treatment of acute respiratory patients.

Investigation of the Mechanism of Action of Qingzaojiufei Decoction on Idiopathic Pulmonary Fibrosis Based on Network Pharmacology and Experimental Validation

Objective: The Traditional Chinese Medicine Qingzao Jiufei Tang decoction (QZJFD) is effective for the treatment of idiopathic pulmonary fibrosis (IPF). In this study, we explored the anti-pulmonary fibrosis effect of QZJFD and the underlying mechanism. Methods: The effects of QZJFD at low, medium, and high doses were investigated in a rat model of lung fibrosis induced by tracheal injection of bleomycin; pirfenidone was included as a positive control. Serum levels of interleukin-6 (IL-6), tumor necrosis factors (TNF-α), and IL-1β in rats were detected by enzyme-linked immunosorbent assay (ELISA). Expression of α-smooth muscle actin (α-SMA), TGF-β1, p-Jun N-terminal kinase (p-JNK), JNK, p-P38 mitogen-activated protein kinase (MAPK), P38 MAPK, collagen I, and fibronectin-1 (FN1) in lung tissues was detected by immunofluorescence labeling and western blot analysis. Results: QZJFD contained 209 main components and 575 corresponding targets. In total, 3875 disease action targets were related to IPF, with 308 common targets shared by drugs and diseases. The key targets included albumin (ALB), recombinant protein, TNF, IL-6, and tumor protein p53. In total, 3061 items were identified in the gene ontology enrichment analysis ( P &lt; .05) and 197 signaling pathways in the Kyoto encyclopedia of genes and genomes ( P &lt; .05), including MAPK, calcium, advanced glycosylation end products - receptors, TNF, and IL-17. Molecular docking simulation showed that the 2 predominant compounds of QZJFD, naringenin, and kaempferol, bound with high affinity to ALB. Serum levels of IL-6, TNF-α, and IL-1β and the expression levels of α-SMA, TGF-β1, p-JNK, p-P38 MAPK, collagen I, and FN1 in lung tissues were significantly increased in the model rats ( P &lt; .001). After treatment with pirfenidone and QZJFD at the medium and high doses, serum levels of IL-6, TNF-α, and IL-1β and expression levels of α-SMA, p-JNK, p-P38 MAPK, collagen I, and FN1 in lung tissues of rats were significantly lower than those in the model group ( P &lt; .05). Conclusions: QZJFD may exert antifibrotic and anti-inflammatory effects that improve the status of IPF by regulating the MAPK signaling pathway.

Elevated expression of interleukin-6 (IL-6) and serum amyloid A (SAA) in the skin and the serum of recessive dystrophic epidermolysis bullosa: Skin as a possible source of IL-6 through Toll-like receptor ligands and SAA.

The effect of persistent skin inflammation on extracutaneous organs and blood is not well studied. Patients with recessive dystrophic epidermolysis bullosa (RDEB), a severe form of the inherited blistering skin disorder, have widespread and persistent skin ulcers, and they develop various complications including anaemia, hyperglobulinaemia, hypoalbuminaemia and secondary amyloidosis. These complications are associated with the bioactivities of IL-6, and the development of secondary amyloidosis requires the persistent elevation of serum amyloid A (SAA) level. We found that patients with RDEB had significantly higher serum levels of IL-6 and SAA compared to healthy volunteers and patients with psoriasis or atopic dermatitis. Both IL-6 and SAA were highly expressed in epidermal keratinocytes and dermal fibroblasts of the skin ulcer lesions. Keratinocytes and fibroblasts surrounding the ulcer lesions are continuously exposed to Toll-like receptor (TLR) ligands, pathogen-associated and damage-associated molecular pattern molecules. Invitro, TLR ligands induced IL-6 expression via NF-κB in normal human epidermal keratinocytes (NHEKs) and dermal fibroblasts (NHDFs). SAA further induced the expression of IL-6 via TLR1/2 and NF-κB in NHEKs and NHDFs. The limitation of this study is that NHEKs and NHDFs were not derived from RDEB patients. These observations suggest that TLR-mediated persistent skin inflammation might increase the risk of IL-6-related systemic complications, including RDEB.

Clinical Efficacy and Nursing Efficiency Analysis of Jiuwei Zhusheng Decoction in Promoting Cervical Ripening in the Perinatal Midwifery Holistic Care

To evaluate the clinical efficacy of Jiuwei Zhusheng Decoction (JWZSD) and perinatal midwifery holistic nursing care in promoting cervical ripening, we conducted a randomized controlled trial involving 80 primiparous and full-term pregnant women with indications for labor induction. The participants were divided into a control group (n = 40) receiving intravenous oxytocin for labor induction and a study group (n = 40) receiving oral administration of JWZSD. Additionally, 30 female Wistar pregnant rats were randomly assigned to the blank group, oxytocin group, and traditional Chinese medicine (TCM) group to compare relevant indicators. In the clinical study, both groups showed significant increases in Bishop scores after treatment. However, the study group demonstrated significantly greater improvements compared to the control group. Moreover, the study group exhibited higher rates of clinical effectiveness and successful vaginal delivery than the control group. In the animal experiment, both the oxytocin and TCM groups displayed disorganized and relaxed cervical connective tissue with evident interstitial edema when compared to the blank group. Furthermore, rats in the TCM group exhibited significantly elevated serum levels of interleukin-8 (IL-8), matrix metalloproteinase-9 (MMP-9), prostaglandin E2 (PGE2), and cyclooxygenase-2 (COX-2) compared to those in the oxytocin group. The combination of JWZSD and perinatal midwifery holistic nursing care for labor induction can effectively enhance cervical ripening and reduce the incidence of cesarean section, potentially through the regulation of IL-8, MMP-9, COX-2, and PGE2 expression. However, further investigations are required to elucidate the underlying mechanisms.

Lysolecithins improved growth performance, nutrient digestibility, immunity, and antioxidant ability in broiler chickens.

This study investigated the effects of dietary supplementation with lysolecithins (LPC) on growth performance, nutrient digestibility, blood profiles, immunity, and liver health in broiler chickens. A cohort of 240 one-day-old male Arbor Acres broilers of comparable weight was divided into four treatment groups, each comprising six replicates of 10 birds. The groups were defined as follows: positive control with recommended metabolizable energy (PC+ME), negative control with 90 kcal/kg reduced ME (NC+ME), PC supplemented with 300 mg/kg LPC (PC+LPC), and NC supplemented with 300 mg/kg LPC (NC+LPC). LPC supplementation led to a statistically significant reduction in the feed conversion ratio (p = 0.05) and a decrease in the proportion of abdominal fat and the liver (p<0.05). Digestibility of dry matter was also enhanced (p<0.05). Malondialdehyde concentrations in the liver were significantly reduced by LPC (p<0.01), with a noteworthy interaction between energy levels and LPC affecting this reduction (p<0.05). Serum levels of interleukin-6 were reduced on day 21, and both endotoxin and interleukin-6 levels were lower on day 42. Notably, a significant interaction was observed between the energy levels and LPC on relative liver weight and endotoxin concentrations in the serum (p<0.05). The study concluded that LPC positively affects growth performance, nutrient digestibility, immune response, and antioxidative capacity in broiler chickens, affirming its value as a beneficial feed additive in poultry nutrition.

Association of dietary inflammatory index with C-reactive protein and interleukin-6 in women with and without polycystic ovarian syndrome

Considering that interventions related to lifestyle, especially nutrition have been proposed as the first line of prevention and treatment of polycystic ovarian syndrome (PCOS), and regarding the proven relationship between PCOS and inflammation, the present study was designed to find out the possible association of Diet Inflammatory Index (DII) with the inflammatory markers like C-reactive protein (CRP) and Interleukin-6 (IL-6), and compare the obtained results in PCOS and non-PCOS women. This case–control study was conducted on 45 PCOS and 40 non-PCOS women. Food intake and DII were measured using a 147-item Food Frequency Questionnaire. All participants were tested for the serum levels of IL-6 and CRP. Finally, the obtained results were compared between the two groups of PCOS and non-PCOS women. Significant differences were observed between the two groups in terms of age, menstrual status and number of pregnancies (P < 0.05). Comparison of DII values showed no significant difference between the two groups of women (P = 0.68), but IL-6 was significantly higher in the PCOS group than in the control group (4.94 ± 1.97 vs. 3.48 ± 1.77, P < 0.001). Also in terms of CRP, no significant difference was observed between the two groups (P > 0.05). The difference of DII between the case and control groups were not significant and Pearson's correlation test did not show a significant correlation between DII and IL-6 (P˃0.05). This result can be due to the influence of several factors affecting the determination of DII such as education level, health status, physical activity level, age, and calorie intake. It seems that diet, especially consumption of more carbohydrates plays a role in causing chronic inflammation, as well as the occurrence and exacerbation of PCOS.

The measurement of hypoxia-inducible factor-1α and interleukin-6 levels in pregnancies with threatened preterm labor

Background: Preterm birth has a significant impact on neonatal health and the healthcare system as it increases neonatal morbidities and mortality rates. Interleukin-6 is one of the pro-inflammatory cytokines that can trigger the production of chemokines and uterine activation proteins, consequently causing uterine contraction and subsequent cervical change. Hypoxia-inducible factor-1α plays a pivotal role in the hypoxic adaptive response of tissues. It has been suggested that hypoxia has a vital role in the initiating and/or strengthening of uterine contractions, proposing that hypoxia-inducible factor-1α could be involved in this process. Aim: Investigate whether serum concentrations of interleukin-6 and hypoxia-inducible factor-1α would differ between women with threatened preterm labor who deliver prematurely and those who continue their pregnancy till term. Patients and Methods: The case-control study was extended over 12 months, including women in their 28th to 35th weeks of gestation and with a single viable fetus. The women were divided into three groups: women with threatened preterm labor who delivered prematurely (27 women), women with threatened preterm labor who continued their pregnancy till term (23 women), and women with matching gestational age and uncomplicated pregnancies (the controls = 40 women). The serum levels of interleukin-6 and hypoxia-inducible factor-1α were measured by Enzyme-linked immunosorbent assay. Results: The mean values of interleukin-6 and hypoxia-inducible factor-1α were significantly different between the study groups (p-value &lt;0.001 by one-way ANOVA), where women with threatened preterm labor who delivered prematurely had higher serum values of interleukin-6 and hypoxia-inducible factor-1α (124.5 and 102.4, respectively) than the women with threatened preterm labor who continued their pregnancy till term (71.0 and 55.2, respectively), and than the women in the control group (55.3 and 50.0, respectively). There was a significant negative statistical correlation between the values of interleukin-6 and hypoxia-inducible factor-1α and the timing of delivery (R = -0.786 and -0.644, respectively, p-value &lt; 0.001). Conclusions: Both interleukin-6 and hypoxia-inducible factor-1α serum concentrations can help differentiate pregnant women who are genuinely in preterm labor from those who have preterm contractions but are not at risk of imminent delivery.

Ex vivo observation of Pythium insidiosum-antigen treated neutrophils on three Pythium insidiosum strains isolated from vascular pythiosis patients

ABSTRACT The mechanisms of Pythium insidiosum-antigen (PIA) immunotherapy activating a patient’s immune system are unknown. We evaluated the interleukin-8 (IL-8) serum levels during P. insidiosum infection and after vaccination with PIA in vascular pythiosis cases. Furthermore, we studied the anti-P. insidiosum activity of neutrophils stimulated with various concentrations of PIA ex vivo in 3 strains of P. insidiosum isolated from vascular pythiosis patients. IL-8 serum levels were evaluated using the ELISA technique. We assessed the effect of PIA-stimulated neutrophils on the viability of zoospores using MTT assay, visualized neutrophil extracellular trap (NET) formation via microscopy, and measured the levels of double-stranded DNA (dsDNA) using PicoGreen dsDNA quantitation assay in 3 strains of P. insidiosum isolated from vascular pythiosis patients. Serum levels of IL-8 gradually lowered from the early to the end phases of vaccination with PIA among the surviving group of vascular pythiosis cases. Neutrophils stimulated with 0.01 µg/ml PIA reduced zoospore viability significantly compared to PIA-unstimulated neutrophils for strain 1 and strain 3 (p < .05). Neutrophils stimulated with 0.01, 0.1, 1, and 10 µg/ml PIA exhibited significantly lower zoospore viability than PIA-unstimulated neutrophils for strain 2 (p < .05). IL-8 can be used as a biomarker for monitoring vascular pythiosis cases treated with the PIA vaccine. Also, anti-P. insidiosum activity of PIA-stimulated neutrophils was probably due to the disruption of cellular activity in zoospores rather than the mechanisms based on the formation of NETs.

Association between Dietary Inflammatory Index and Bone Mineral Density Changes among Pregnant Women: A Prospective Study in China.

This study aims to examine the relationship between dietary inflammatory index (DII) and bone mineral density (BMD) changes among Chinese pregnant women, offering valuable insights for dietary guidance during pregnancy. 289 pregnant women were enrolled in this cohort. Serum inflammatory factors and ultrasonic BMD were measured at the first, second, and the third trimesters. DII scores were calculated based on a semi-quantitative food frequency questionnaire (FFQ) and divided into tertiles. We compared the differences in inflammatory factors in serum across the tertiles of DII and changes in BMD at the second and third trimesters across the tertiles. The participants with higher DII scores had higher total energy intakes than those with lower DII scores. The serum level of interleukin-6 (IL-6) was significantly different across the tertiles of the DII. Women who had lower DII scores had higher T-scores and Z-scores in the BMD assessment. In the test of trends, after adjusting potential covariates, including educational level, physical activity, body mass index, and calcium, vitamin D, or multivitamin supplements, DII values were determined to be positively related to the maternal BMD lost. DII was positively associated with serum IL-6. Meanwhile, higher DII scores were associated with more bone mass loss in pregnant women. We recommend adhering to a lower-DII diet to preserve BMD during pregnancy.
