Serum Levels Of Interleukin Research Articles

The evaluation of the serum levels of vitamin D and interleukin-33 in children with atopic dermatitis and its association with diseases severity.

Atopic dermatitis (AD) is a chronic inflammatory disease characterized by increased skin sensitivity to environmental elements, mediated by CD4+ T helper cells (Th2). Interleukin-33 (IL-33) plays a critical role in exacerbating symptoms in inflamed tissues. Conversely, vitamin D has been shown to induce antimicrobial peptides and suppress the inflammatory response. Therefore, the purpose of this study was to investigate the correlation between serum levels of vitamin D and IL-33 in children with Atopic dermatitis. Blood samples were collected from 51 patients with Atopic dermatitis and 20 healthy control cases. After counting the blood cells, serum was isolated by centrifugation, and the levels of IL-33, Immunoglobulin E (IgE), and vitamin D were measured using ELISA. Statistical analysis of the collected data was performed using SPSS version 26 software. Our findings revealed significant differences in the levels of IL- 33 (p value < 0.001), IgE (p value 0.005), and blood cell parameters including Hemoglobin (HGB) (p value < 0.001), Hematocrit (HCT) (p value < 0.001), Mean Corpuscular Hemoglobin (MCH) (p value 0.001), Mean Corpuscular Hemoglobin Concentration (MCHC) (p value < 0.001), lymphocyte count (p value 0.02), and monocyte count (p value < 0.001) in AD patients compared to the control group. Additionally, there was a significant correlation between IL-33, and vitamin D serum levels in AD patients (p value 0.03). The current study has revealed a significant difference in the serum levels of IL-33 and IgE between AD patients and healthy individuals. This suggests a potential role for these variables in the pathophysiology of AD disease.

Impacts of supplementation with milk proteins on inflammation: a systematic review and meta-analysis.

Impacts of milk proteins (MPs) on inflammation are uncertain. The current systematic review and dose-response meta-analysis of randomized controlled trials (RCTs) evaluated the effects of whey protein (WP), casein protein (CP), or MP supplementation on serum levels of cytokines and adipokines in adults. A comprehensive search of various online databases was conducted to find appropriate clinical trials published until September 2024. A random-effect statistical model was implemented. The meta-analysis included 53 RCTs. It was indicated that MP supplements had no substantial effects on serum values of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), adiponectin, and leptin. However, there were statistically significant decreases in serum levels of interleukin-6 (IL-6) following supplementation with MP (weighted mean difference (WMD): -0.25pg/mL, 95% CI -0.48, -0.03; P = 0.026) in the intervention group compared with the control group. This study revealed that MP supplementation may not have any considerable impacts on the levels of cytokines and adipokines.

Treatment with Sulodexide Downregulates Biomarkers for Endothelial Dysfunction in Convalescent COVID-19 Patients.

Persistent elevation of biomarkers associated with endothelial dysfunction in convalescent COVID-19 patients has been linked to an increased risk of long-term cardiovascular complications, including long COVID syndrome. Sulodexide, known for its vascular endothelial affinity, has demonstrated pleiotropic protective properties. This study aims to evaluate the impact of sulodexide on serum levels of endothelial dysfunction biomarkers in patients during the convalescent phase of COVID-19. We conducted a double-blind, single-center, randomized, placebo-controlled trial in Mexico, comparing sulodexide (250 LRU orally, twice daily) with placebo over 8 weeks in adult patients during early COVID-19 convalescence. Differences in serum biomarkers between the groups were analyzed using repeated measures and post hoc tests, with Thrombomodulin (TM) as the primary endpoint. Among 206 analyzed patients (103 in each group), at week 8, the sulodexide group exhibited significantly lower mean levels of Thrombomodulin (TM) (25.2 ± 7.9 ng/mL vs 29.9 ± 14.7 ng/mL, P = .03), von Willebrand Factor (vWF) (232 ± 131 U/dL vs 266 ± 122 U/dL, P = .02) and Interleukin-6 (IL-6) (12.5 ± 13.2 pg/mL vs 16.2 ± 16.5 pg/mL, P = .03) compared to the placebo group. D-dimer and C reactive protein (CRP) in the sulodexide group were also lowered. No significant differences were observed for P-selectin, fibrinogen, VCAM-1, or ICAM-1 levels. Patients in the convalescent phase of COVID-19 who received sulodexide for eight weeks showed a reduction in TM, vWF, D-dimer, CRP, and IL-6 serum levels compared to placebo. These findings suggest a potential protective effect of sulodexide against thromboinflammation and endothelial damage.

Compartmentalization of the Inflammatory Response in the Pericardial Cavity in Patients Undergoing Cardiac Surgery.

The systemic inflammatory response after cardiopulmonary bypass has been widely studied. However, there is a paucity of studies that focus on the local inflammatory changes that occur in the pericardial cavity. The purpose of this study is to assess the inflammatory mediators in the pericardial fluid of patients undergoing cardiac surgery. We conducted a prospective cohort study on patients undergoing aortic valve replacement. Pericardial fluid and peripheral venous blood samples were collected after the opening of the pericardium. Additional samples were obtained from peripheral blood and the pericardial fluid shed through mediastinal drains 24 and 48 h after surgery. Levels of interleukin 1α (IL-1α), interleukin 1β (IL-1β), interleukin 2 (IL-2), interleukin 4 (IL-4), interleukin 6 (IL-6), interleukin 8 (IL-8), interleukin 10 (IL-10), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), vascular endothelial growth factor (VEGF), monocyte chemotactic protein-1 (MCP-1), epidermal growth factor (EGF), soluble E-selectin, L-selectin, P-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) were determined in all pericardial fluid and serum samples. A total of 45 patients with a mean age of 74 years were included, of which 66% were males. Serum levels of IL-6, IL-8, and MCP-1 were significantly increased at 24 and 48 h after surgery. No significant changes were observed in the serum levels of the remaining mediators. A significant increase of postoperative pericardial fluid levels of IL-1α, IL-1β, IL-6, IL-8, IL-10, IFN-γ, VEGF, MCP-1, VCAM-1, and P-selectin was observed at 24 and 48 h after surgery. There is a robust systemic and pericardial inflammatory response after cardiac surgery on cardiopulmonary bypass. However, postoperative pericardial inflammatory activity shows a distinct pattern and is more marked than at the systemic level. These findings suggest that there is a compartmentalization of the inflammatory response within the pericardial cavity after cardiac surgery.

Exploring the Impact of IL-33 Gene Polymorphism (rs1929992) on Susceptibility to Chronic Spontaneous Urticaria and Its Association with Serum Interleukin-33 Levels.

Urticaria is a debilitating skin condition affecting up to 20% of the global population, characterized by erythematous, maculopapular lesions and significant quality of life impairment. This study focused on the role of interleukin 33 (IL-33) and its polymorphisms, particularly SNP rs1929992, in chronic spontaneous urticaria (CSU). Using demographic, clinical, and laboratory data from CSU patients and controls, we estimated allele and genotype frequencies, Hardy-Weinberg equilibrium condition, and serum IL-33 levels, using unconditional binomial logistic regression for association analysis. Results revealed that CSU patients had significantly higher frequencies of the minor allele of IL-33 rs1929992 compared to controls (31.25% vs. 17.35%, p = 0.024), and carriers of the GA genotype exhibited increased odds of CSU (adjusted OR = 2.208, p ≤ 0.001). Additionally, serum IL-33 levels were markedly elevated in CSU patients, particularly those with the GA genotype. The findings suggest that the IL-33 SNP is associated with an increased susceptibility to CSU, emphasizing its potential as a diagnostic and therapeutic biomarker. This study underscores the genetic and immunological underpinnings of CSU, paving the way for personalized treatment approaches.

Diagnostic value of interleukins 23 and 17 in the assessment of ulcerative colitis severity

Background. Ulcerative colitis (UC) is a chronic bowel disease with a complex aetiology that includes immune, genetic and environmental factors. Its progression and severity vary greatly, suggesting that different cytokine pathways may be responsible for the heterogeneity of clinical outcomes. The purpose of the study was to investigate the state of cytokine regulation of inflammation depending on the severity of UC. Materials and methods. We examined 32 patients with UC who were treated at the Department of Intestinal Diseases of the State Institution “Institute of Gastroenterology of the National Academy of Medical Sciences of Ukraine”. Patients were divided into groups depending on disease severity determined by the Mayo index: moderate UC — 24 individuals, severe UC — 8 patients. Serum levels of interleukin (IL) 17 and IL-23 were determined by enzyme-linked immunosorbent assay. The study was performed according to the instructions for each test kit. Statistical processing of the results was done using the Statistica 6.1 software package. Results. The content of proinflammatory cytokines in the examined patients with UC was significantly higher than in the control group: IL-17 — by 9.0 times (р &lt; 0.05), the median level of IL-23 — 8.6-fold (р &lt; 0.05). When analysing the data depending on the disease severity, it was found that IL-17 was significantly higher in patients with moderate (by 9.9 times, р &lt; 0.05) and severe UC (by 9.1 times, р &lt; 0.05) than in controls. The median level of IL-23 was significantly higher in moderate (by 8.3 times, р &lt; 0.05) and severe UC (by 13.2 times, р &lt; 0.05) compared to that of the control group. In addition, with severe UC, the concentration of IL-23 was 1.6 times than in moderate UC. A correlation was found between the levels of IL-17 and IL-23 in patients with UC (r = +0.361; p = 0.042). Conclusions. The content of proinflammatory cytokines in UC has reliable differences vs. control group: IL-17 is significantly higher, by 9.0 times (р &lt; 0.05), and IL-23 — by 8.6 times (р &lt; 0.05). It was found that among patients with UC, the level of IL-23 was higher in those with severe course. Thus, quantitative determination of IL-17 and IL-23 levels in the blood serum of patients with UC can be a useful clinical tool for stratification by disease severity and help choose therapy.

Assessment of Interleukin-17A and Interleukin-2 Serum Levels in Patients with Alopecia Areata

Background: Alopecia areata (AA) is a condition that leads to the loss of hair in the part of the body due to the destruction of hair follicles, and causing patchy, non-scarring hair loss. The source of AA is unclear; however, there is much evidence assuming that alopecia areata is a disease mediated by the immune system. Aim: To measure the levels of serum interleukin (IL-17A and IL-2) in alopecia areata patients and their associations with the severity and period of illness, along with other prognostic disease variables. Materials and Methods: To perform the study, 40 patients with alopecia areata and 40 healthy controls were registered. The serum levels of IL-2 and IL-17A in alopecia areata patients and healthy controls were evaluated by applying ELISA techniques (Sandwich ELISA). Results: Compared to the healthy group, patients with alopecia areata revealed much higher levels of IL-17A and IL-2 (p &gt; 0.05). Baseline interleukin levels did not associate statistically significantly with the severity or period of the disease. Conclusions: The current study suggests that IL-17A and IL-2 were strongly linked with alopecia areata and may have a crucial role in the condition's progress.

Effect of Chromium Supplementation on Serum Levels of Inflammatory Mediators: An Updated Systematic Review and Meta-analysis on Randomized Clinical Trials.

Chromium has been recognized for its beneficial effects on inflammation reduction; therefore, we conducted a systematic review and meta-analysis to find the effect of chromium supplementation on serum levels of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) in subjects aged 18years and older. Related articles were identified by searching databases such as the Cochrane Library, ClinicalTrials.gov, ISI Web of Science, Scopus, and PubMed up until Agust 2024. We computed the mean differences (MD) along with their standard deviations (SDs) to carry out the meta-analysis. Statistical heterogeneity of the intervention effects was assessed using I-squared statistics and Cochran's Q test. In total, twelve and eleven studies were included in the present systematic review and meta-analysis, respectively. The pooled results indicated that the differences in serum levels of CRP and TNF-α between chromium group and the comparison group were statistically significant (CRP: weighted mean difference (WMD) = -0.58mg/L; 95% confidence interval (CI) = -0.95, -0.22mg/L; P = 0.002; TNF-α: WMD = -1.22pg/ml; 95% CI = -1.91, -0.53pg/ml; p = 0.001). In contrast, chromium supplementation resulted in a non-significant decrease in serum levels of IL-6 (WMD = -0.63pg/ml; 95% CI: -1.67, 0.4pg/ml; P < 0.001). Our study supports the beneficial effect of chromium supplementation on serum concentration of CRP and TNF-α, but our results showed that chromium supplementation non-significantly reduced the serum levels of IL-6. However, it seems that chromium formulation, participants' BMI, sample size, and geographical region are strong variables that predict the effect of chromium supplementation on inflammatory mediators.

Effect of electroacupuncture pretreatment on the quality of recovery in the patients undergoing laparoscopic gastrointestinal surgery

To investigate the effect of electroacupuncture pretreatment on the quality of recovery in the patients undergoing laparoscopic gastrointestinal surgery. Sixty patients for elective laparoscopic resection of gastrointestinal tumors under general anesthesia were randomly assigned to either an observation group or a control group, with 30 patients in each group. In the control group, the routine inhalation-intravenous combined general anesthesia was adopted. On the basis of the control group, in the observation group, 30 min before anesthesia induction, electroacupuncture was applied to bilateral Neiguan (PC 6) and Neimadian (Extra) for 30 min, using disperse-dense wave and at 2 Hz/100 Hz. The recovery time of spontaneous breathing, awakening time, extubation time, and the post-anesthesia care unit (PACU) stay time were compared between the two groups. Mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SpO2) were recorded at multiple time points: before electroacupuncture (T0), before extubation (T1), immediately after extubation (T2), 5 minutes (T3) and 10 minutes (T4) after extubation, and upon discharge from PACU (T5). The visual analogue scale (VAS) score for pain and Ramsay sedation score at T3, T4 and T5 were observed; and the incidence of agitation, nausea and vomiting at T5 was evaluated in the two groups. At T0 and T5, the serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and cortisol were determined in the two groups. In the observation group, the recovery time of spontaneous breathing, awakening time, extubation time, and PACU stay time were shorter (P<0.001), MAP and HR at T2 were lower (P<0.01, P<0.05), the VAS scores for pain at T3, T4, and T5 dropped (P<0.001, P<0.01), and the Ramsay sedation score at T3 reduced (P<0.05) compared with those in the control group. The incidence of nausea and vomiting was lower in the observation group when compared with that in the control group (P<0.05). In comparison with the indexes at T0, the serum levels of TNF-α, IL-6, and cortisol increased at T5 in both groups (P<0.01); and these indexes at T5 in the observation group were lower than those in the control group (P<0.01, P<0.05). Electroacupuncture pretreatment can enhance the quality of recovery in the patients undergoing laparoscopic gastrointestinal tumor surgery, shorten the time for spontaneous breathing recovery, awakening, extubation and PACU stay, and attenuate postoperative pain and stress response.

Impact of Serum GDF-15 and IL-6 on Immunotherapy Response in Cancer: A Prospective Study.

Immunotherapy has transformed cancer treatment; however, predicting treatment response remains challenging. Serum biomarkers can help identify patients who are most likely to benefit from immunotherapy. This study evaluates the relationship between serum growth differentiation factor 15 (GDF-15) and interleukin-6 (IL-6) levels and treatment outcomes in cancer patients undergoing second-line immunotherapy. We conducted a prospective observational study involving 85 patients with non-small-cell lung cancer (NSCLC), renal cell carcinoma (RCC), or malignant melanoma treated with nivolumab. The baseline serum levels of GDF-15 and IL-6 were measured by using ELISA kits. The primary endpoints were progression-free survival (PFS) and overall survival (OS), with cachexia as a secondary outcome. Elevated GDF-15 levels were significantly associated with shorter PFS (HR: 0.55, 95% CI: 0.32-0.96, p = 0.032) and OS (HR: 0.47, 95% CI: 0.25-0.90, p = 0.020). Higher IL-6 levels correlated with shorter PFS, though statistical significance was not achieved. Additionally, high GDF-15 levels were linked to increased cachexia incidence (p = 0.037). Our findings indicate that GDF-15 could serve as a prognostic biomarker for immunotherapy response and may also be a target for cachexia management. Further studies should explore its potential to guide clinical decision making in oncology.

Effectiveness of the quercetin use in patients with COVID-19 with concomitant type 2 diabetes mellitus

AimTo conduct a comparative analysis of the effectiveness of basic therapy and basic therapy with the inclusion of quercetin in patients with COVID-19 with concomitant type 2 diabetes.Material and methodsThere were examined 60 patients with COVID-19 with concomitant T2DM. Upon admission into the hospital and again after 10 days, serum levels of interleukin-6, C-reactive protein, procalcitonin, ferritin, endothelin-1 were determined, and capillaroscopy of the nail plate was performed. Patients of the group I (30) against the background of protocol therapy received 0.5 g of quercetin intravenously once a day for 10 days. Patients of the group II (30) received to basic therapy.ResultsAfter the treatment in patients of the group I general weakness decreased, body temperature normalized, improved saturation indicators, the level of acute-phase parameters (interleukin-6, CRP and ferritin) significantly decreased, a positive effect of quercetin on the level of D-dimer in blood serum was noted, indices of pericapillary edema and hemosiderin deposition significantly decreased, indices diameter of the arterial part of the capillary and capillary network density significantly increased.ConclusionsThe use of quercetin against the background of basic therapy in patients with COVID-19 and concomitant T2DM reliably reduces the level of acute-phase indices, has an important clinical significance for reducing endothelial dysfunction and for preventing thrombotic complications.

Effect of Saffron (Crocus sativus) Supplementation on Oxidative Stress, Inflammatory Indices, and Renal and Liver Function Parameters in Patients With Type 2 Diabetes Mellitus: A GRADE-Assessed Systematic Review and Meta-analysis of Randomized Clinical Trials.

Clinical investigation has shown that the addition of saffron or crocin to standard antidiabetic medications improves a patient's metabolic profile, oxidative stress (OS), and inflammatory response. Despite a large number of studies examining the impact of saffron supplementation on OS, inflammation, and renal and liver function parameters, no systematic review or meta-analysis has been conducted to compile the outcomes in patients with type 2 diabetes mellitus (T2DM). The current systematic review and meta-analysis was performed to investigate the effect of saffron or crocin intake on OS, inflammation, and renal and liver function parameters in patients with T2DM. Online databases including PubMed, Scopus, ISI Web of Science, and Cochrane Library were searched up to December 2023. The mean differences and their respective SDs were extracted. Using a random-effects model, the pooled data were calculated as standardized mean difference (SMD) with 95% CI. 17 eligible randomized controlled trials were included in this meta-analysis. The pooled findings showed that saffron supplementation remarkably decreased the levels of tumor necrosis factor-α (SMD: -0.37; 95% CI: -0.69 to -0.05; I2 = 40.77%, P = .15), interleukin-6 (IL-6) (SMD: -0.38; 95% CI: -0.65 to -0.10; I2 = 0%, P = .68), and malondialdehyde (MDA) (SMD: -0.36; 95% CI: -0.65 to -0.07; I2= 20.51%, P = .02) compared with the control. In addition, based on subgroup analyses, taking ≥100 mg of saffron daily in individuals with T2DM reduced the serum levels of IL-6 (SMD: -0.50; 95% CI: -0.90 to -0.10; I2 = 0%, P = .50) and MDA (SMD: -0.36; 95% CI: -0.68 to -0.03; I2 = 0, P = .97). Furthermore, the level of alanine transaminase was decreased (SMD: -0.43; 95% CI: -0.73 to -0.12; I2 = 0, P = .66) with a treatment period of <60 days of saffron or crocin supplementation. Larger studies with more follow-up and higher doses of both saffron and crocin are needed in order to understand the efficacy and safety of these herbs for long-term use as routine therapies.

The Therapeutic Role of Gastrodin in Combating Insulin Resistance, Inflammation, and Oxidative Stress Induced by Bisphenol-A

Objective Insulin resistance is a key feature of, type 2 diabetes mellitus (T2DM), and it has been linked to an environmental pollutant bisphenol-A (BPA). Gastrodin, a derivative of Chinese medicinal herb, has antioxidant and anti-inflammatory properties that can potentially ameliorate BPA-induced insulin resistance in albino rats. Method The study involved five groups of six rats each, including normal control, BPA-treated, metformin-treated, and gastrodin plus BPA-treated groups Insulin sensitivity index, homeostasis model assessment- index of insulin resistance (HOMA IR), and fasting insulin levels were assessed. Using ELISA, the study measured protein levels, including High-Sensitivity C-reactive Protein (hs-CRP,) Glucose Transporter 1 (GLUT1), Interleukin-6 (IL-6), Tumor Necrosis Factor-alpha (TNF-α), AMP-Activated Protein Kinase (AMPK), Inducible Nitric Oxide Synthase (iNOS), caspase-3, and Nuclear factor erythroid 2–related factor 2 (Nrf2), and analyzed factors like thiobarbituric acid reactive substances-malondialdehyde (TBARS-MDA), reduced glutathione, and catalase activity. Results BPA administration causes insulin resistance in albino rats, reducing insulin sensitivity. Gastrodin treatment attenuates resistance, improves glucose levels, and increased insulin sensitivity. Gastrodin also mitigates oxidative stress.by reducing reactive oxygen species (ROS) production and restoring antioxidant enzyme activities, while TBARS-MDA was reduced. Studied inflammatory indicators included; C-reactive protein, Tumor necrosis factor (TNF-α), and Interleukin 6. Notably, the administration of bisphenol-A caused a 2–3 fold increase in the serum levels of hs-CRP, TNF-α, and IL-6. All treatments by gastrodin (high and low doses) decreased these observed effects by bisphenol-A to values similar to the standard (metformin) and normal control rats. Gastrodin exerted its protective benefits via activating the AMPK/Nrf2 signaling pathway, increasing AMPK phosphorylation and Nrf2 nuclear translocation, resulting in improved cellular defense against oxidative stress. Indicators of possible inflammations on bisphenol-A treatment were also investigated. Conclusion This shows that gastrodin might be a promising therapeutic drug for the prevention and treatment of insulin resistance-related problems.

Study on protective effect and mechanism of Shouhui Tongbian Capsules on cerebral ischemia-reperfusion rat models based on metabolomics

This paper explored the protective effect and potential mechanism of Shouhui Tongbian Capsules(SHTB) on cerebral ischemia-reperfusion rat models. Rats were randomly divided into sham surgery group, model group, low-dose SHTB group(0.2 g·kg~(-1)·d~(-1)), high-dose SHTB group(SHTB g·kg~(-1)·d~(-1)), and an edaravone positive drug group(5.4 mg·kg~(-1)·d~(-1)), with 12 rats in each group. Rats were given continuous intragastric administration seven days before surgery, and the suture method was used to establish the cerebral ischemia-reperfusion injury(CIRI) rat model. Zea-Longa rating scale for neurological functions was used to assess the degree of neurological function impairment in rats; hematoxylin-eosin(HE) staining was used to observe the pathological damage of rats' brain tissue; TTC staining was used to measure the area of cerebral infarction in rats; enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of interleukin-6(IL-6), interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α) in each group. Western blot was used to detect the level of tight junction protein associated with the blood-brain barrier and intestinal barrier, as well as the protein expression of the TLR4/MyD88/NF-κB pathway in brain tissue. Changes in rats' brain tissue and metabolites in serum were detected by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS), so as to explore the potential mechanism of SHTB treatment for CIRI in rats. Compared with the model group, SHTB could significantly alleviate the pathological damage to the brain of CIRI rats, reduce the volume of cerebral infarction, and lower the level of inflammation in the serum; Western blot results showed that SHTB could regulate the expression of tight junction proteins related to the blood-brain barrier and intestinal barrier in CIRI rats and downregulate the expression of TLR4, NF-κB, and MyD88 proteins in brain tissue. The UPLC-MS/MS results indicated that SHTB could significantly regulate the content of potential differential metabolites such as fatty acids, and serum and brain tissue are involved in pathways such as unsaturated fatty acid biosynthesis. SHTB could repair intestinal barrier function, reduce inflammation levels in the body, and improve the damaged blood-brain barrier, exerting a protective effect on brain nerves. Its mechanism may be achieved by balancing fatty acid metabolism and regulating the expression of TLR4/MyD88/NF-κB signaling pathway proteins.

Internal Quality Network Stress and Inflammation Reaction Indicators in the Expression and Significance of the Serum of Limited Pregnant Women's Serum.

Aims/Background Fetal growth restriction (FGR) is a common clinical disorder in pregnant women. Inflammation and endoplasmic reticulum stress play an important role in the occurrence and development of FGR. The purpose of this study was to explore the expression and significance of endoplasmic reticulum stress and inflammatory response indicators in the serum of pregnant women with FGR. Methods The data of pregnant women admitted to Changzhou Maternal and Child Health Care Hospital from January 2020 to June 2023 were collected and analyzed by propensity score matching (PSM). Pregnant women with FGR were included in the observation group (n = 65), whereas healthy pregnant women admitted to the hospital during the same period were included in the control group (n = 65). Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of inflammatory markers such as tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) in all the pregnant women recruited in this study. The serum levels of glucose regulatory protein 78 (GRP78) and C/EBP homologous protein (CHOP), which are characteristic indicators of endoplasmic reticulum stress, in the two groups of pregnant women, were also detected and analyzed. A range of parameters concerning fetal growth and development indicators, such as fetal head circumference, abdominal circumference and fetal development index, of the two groups of study subjects were recorded and compared. Analyze the correlation between inflammatory response indicators and endoplasmic reticulum stress factors in pregnant women with FGR and fetal growth and development indicators. Results The serum levels of TNF-α, IL-1β and IL-6 in the observation group were significantly higher than those in the control group (p < 0.001). The serum levels of GRP78 and CHOP in the observation group were significantly higher than those in the control group (p < 0.001). The levels of GRP78 and CHOP in pregnant women with FGR were negatively correlated with fetal head circumference, abdominal circumference, and fetal growth and development index (p < 0.05). Conclusion The serum levels of inflammatory markers such as TNF-α, IL-1β and IL-6 in pregnant women with FGR were abnormally elevated, indicating severe inflammatory response. In addition, endoplasmic reticulum stress was observed in pregnant women with FGR, marked by significantly elevated levels of GRP78 and CHOP. The levels of TNF-α, IL-1β, IL-6, GRP78 and CHOP were negatively correlated with fetal head circumference, abdominal circumference and fetal growth and development index, implying their impacts on the occurrence and development of FGR.

Efficacy of serum-free cultured human umbilical cord mesenchymal stem cells in the treatment of knee osteoarthritis in mice.

We investigated the efficacy of intra-articular injection of human umbilical cord mesenchymal stem cells (hUC-MSCs) for the treatment of osteoarthritis (OA) progression in the knee joint. Although many experimental studies of hUC-MSCs have been published, these studies have mainly used fetal bovine serum-containing cultures of hUC-MSCs; serum-free cultures generally avoid the shortcomings of serum-containing cultures and are not subject to ethical limitations, have a wide range of prospects for clinical application, and provide a basis or animal experimentation for clinical experiments. To study the therapeutic effects of serum-free hUC-MSCs (N-hUCMSCs) in a mouse model of knee OA. Fifty-five male C57BL/6 mice were randomly divided into six groups: The blank control group, model control group, serum-containing hUC-MSCs (S-hUCMSC) group, N-hUCMSC group and hyaluronic acid (HA) group. After 9 weeks of modeling, the serum levels of interleukin (IL)-1β and IL-1 were determined. Hematoxylin-eosin staining was used to observe the cartilage tissue, and the Mankin score was determined. Immunohistochemistry and western blotting were used to determine the expression of collagen type II, matrix metalloproteinase (MMP)-1 and MMP-13. The Mankin score and serum IL-1 and IL-1β and cartilage tissue MMP-1 and MMP-13 expression were significantly greater in the experimental group than in the blank control group (P < 0.05). Collagen II expression in the experimental group was significantly lower than that in the blank control group (P < 0.05). The Mankin score and serum IL-1 and IL-1β and cartilage tissue MMP-1 and MMP-13 levels the experimental group were lower than those in the model control group (P < 0.05). Collagen II expression in the experimental group was significantly greater than that in the model control group (P < 0.05). N-hUCMSC treatment significantly alleviate the pathological damage caused by OA. The treatment effects of the S- hUCMSC group and HA group were similar.

The Association of Interleukin 6 Receptor Gene Variant (Rs4129267) with Susceptibility to Ankylosing Spondylitis and Soluble IL-6 Receptor Level in Iranian Patients

Objectives: Ankylosing spondylitis (AS) is an axial skeleton-related auto-inflammatory arthritis. Interleukin 6 (IL-6) and its receptor (IL-6R) play a role in the etiopathology of AS. The recent genome-wide association studies (GWASs) revealed that rs4129267; an intrinsic variant of IL6-R is associated with the risk of AS. We aimed to study the rs4129267 IL6R variant in Iranian AS patients and the correlation of this variant with the soluble interleukin-6 receptor (sIL-6R) serum level. Materials and Methods: In this case-control study, we genotyped rs4129267 IL6-R variant in extracted DNA from 498 AS patients and 495 matched healthy controls by Amplification-Refractory Mutation System Polymerase Chain Reaction (ARMS-PCR). The serum level of sIL-6R and IL-6 was also analysed in 39 controls and 42 AS patients by the ELISA method. The correlation between rs4129267 IL-6R variants and patients’ clinical manifestations and sIL-6R level was also investigated. Results: In comparison to the AS individuals, C allele were significantly less prevalent in the healthy control group (OR = 1.23 [1.01 –1.48], P value = .034). Patients had significantly elevated levels of IL-6 serum levels. There was a significant correlation between the presence of the rs4129267 T allele and increased sIL-6R level. Conclusions: Our study confirmed the significant association between the rs4129267 T variant and the protection against AS disease susceptibility. Increased IL-6 level and reduced frequency of sIL-6R rs4129267 T allele in patients which contributes to reduced sIL-6R serum level, highlights the significant role of IL-6 signalling pathway in AS pathogenesis.

Biochemical Investigation of the Association of Apolipoprotein E Gene Allele Variations with Insulin Resistance and Amyloid-β Aggregation in Cardiovascular Disease.

This article investigates the intricate associations between apolipoprotein E (APOE) gene alleles variation, insulin resistance (IR) and amyloid-β aggregation in cardiovascular disease (CVD) patients. A cohort of 250 patients exhibiting the symptoms of CVD and 50 control subjects participated in this study. After applying the stringent inclusion and exclusion criteria, the diseased group was further stratified into three categories: CVD+ (Alzheimer's disease) AD, CVD + (diabetes mellitus) DM and CVD + DM + AD. Blood samples were collected from all recruited participants for the biochemical analyses of lipid profile, glycaemic status, liver function enzymes, inflammatory and oxidative stress biomarkers. Tetra amplification-refractory mutation system-polymerase chain reaction (ARMS-PCR) was employed for APOE gene analysis. Biochemical evaluations revealed the significant elevations in the serum levels of glucose, liver enzymes, interleukin-6 (IL-6), cholesterol, low-density lipoproteins (LDL), triglycerides (TG) and malondialdehyde (MDA) in CVD + DM + AD group. Conversely, the serum levels of insulin, HDL and hexokinase decreased in CVD + DM + AD group compared to the controls and other CVD groups. Tetra ARMS-PCR results indicated a higher percentage of the risk allele in CVD + DM + AD group when compared with the other groups. Our study elucidates the multifaceted cardiovascular risk factors contributing to IR and AD in CVD patients. Age-related risk factors, prevalence of APOE risk alleles and the impact of statin use on AD incidences were identified. These findings underscore the need for tailored preventive measures, particularly in APOEε4 and ε3/ε4 carriers with CVD. Further studies should delve into the knowledge-based protocols to comprehend the underlying mechanisms. Focusing on the therapeutic targets to prevent or delay DM and AD progression in CVDs, especially in APOEε4 carriers, is essential.
