Serum Interleukin-6 Levels Research Articles

Abdominal wound length influences the postoperative serum level of interleukin-6 and recovery of flatus passage among patients with colorectal cancer.

A mini-laparotomy for colorectal cancer (CRC) has been reported to shorten postoperative ileus (POI) and hospital stay. Interleukin-6 (IL-6) plays a role in intestinal tissue inflammation, leading to POI. This study investigated the effects of abdominal wounds and IL-6 levels on POI in patients having CRC surgery. Forty-three patients with CRC underwent bowel resection. Serum samples were collected preoperatively and at 2, 24, and 48 h after surgery for cytokine quantification by ELISA. Clinical data, including time from surgery to first passage of flatus and postoperative hospital stay, demographic and pathological data, and routine blood tests, were compared statistically with abdominal wound length and the postoperative increments of cytokines (designated as Δ). The length of the abdominal wound showed a significant correlation with clinical variables (length of operation time, time of first flatus passage, and length of postoperative hospital stay) and cytokine variables (IL-6(Δ2 h), IL-8(Δ2 h) and IL-10(Δ2 h). Linear regression analysis showed that the abdominal wound length significantly influenced the operation time, time of first flatus passage, and length of postoperative hospital stay (p < 0.001). The length of the abdominal wound showed a significant influence on the IL-6(Δ2 h) and IL-8(Δ2 h) (p < 0.001, respectively) but no influence on IL-10(Δ2 h). IL-6(Δ2 h), but not IL-8(Δ2 h), significantly influenced the time to first flatus passage and length of hospital stay (p = 0.007, p = 0.006, respectively). The mini-laparotomy approach (wound length <7 cm) led to significantly shortened operation time, time of first flatus passage, length of postoperative stay (p = 0.004, p = 0.003, p = 0.006, respectively) as well as reduced postoperative increment of IL-6(Δ2 h) (p = 0.015). The mini-laparotomy for anterior resection surgery significantly influenced operation time, time of first passage of flatus, length of postoperative stay, and IL-6(Δ2 h). Our study is the first to report the complex interaction among the length of the abdominal wound, IL-6 serum level, recovery of the first passage of flatus, and postoperative hospital stay. These results suggest that smaller abdominal wounds and smaller postoperative IL-6 increments were associated with faster recovery of flatus passage and shorter hospital stays.

Comparative efficacy of peptide-based versus standard polymeric enteral nutrition in ICU patients at high nutritional risk: a multicenter randomized controlled trial

Within intensive care units (ICU), the administration of peptide-based formulas (PBF) may confer nutritional advantages for critically ill patients identified with heightened nutritional risk. This investigation aimed to ascertain the efficacy of PBF in comparison to standard polymeric formulas (SPF) among this patient cohort. A double-blind, randomized controlled trial was conducted across three ICUs, encompassing 63 adult patients characterized by elevated modified Nutrition Risk in Critically Ill (mNUTRIC) scores. Enrollment occurred promptly subsequent to ICU admission, with participants allocated to receive either PBF or SPF. Primary outcome was the duration to achieve caloric targets. Secondary outcomes involved the evaluation of mean daily gastric residual volume, mechanical ventilation period, infection rates within the ICU, length of hospitalization, mortality rates, nutritional status and inflammatory markers, specifically serum albumin and interleukin-6 levels. Patients in the PBF group reached their caloric targets more expeditiously compared to the SPF group (2.06 ± 0.43 days versus 2.39 ± 0.79 days; p = 0.03). No significant differences were discernible between the groups regarding gastric residual volume, duration of mechanical ventilation, ICU length of stay, mortality, or infection rates. Both cohorts exhibited minimal adverse effects and were devoid of any instances of abdominal distension. While not reaching statistical significance, the observed trends in albumin and interleukin-6 levels suggest a potential advantage of PBF utilization. The implementation of PBF enabled swifter attainment of caloric goals in ICU patients at high nutritional risk without adversely impacting other clinical parameters. Given its favorable tolerance profile and potential immunomodulatory properties, PBF may be considered a valuable nutritional intervention in this setting.Thai Clinical Trials Registry TCTR20220221006.

Application of Cefaclor in Orthodontics through Micro-Implant Anchorage in Patients with Periodontitis.

Chronic periodontitis leads to gingival swelling, hyperplasia, and tooth mobility, which affects orthodontic treatment. The aim of this study was to investigate the application of cefaclor in orthodontics through micro-implant anchorage in patients with periodontitis. A retrospective study was conducted on patients with periodontitis who received micro-implant anchorage treatment in the department of orthodontics at the First People's Hospital of Yongkang City from July 2019 to January 2022. According to different treatment regimens, these patients were divided into the test group (patients receiving cefaclor and micro-implant anchorage treatment) and the control group (patients receiving micro-implant anchorage treatment only). The plaque index (PLI), gingival index (GI), sulcus bleeding index (SBI), and serum inflammatory factor levels were compared between the two groups after treatment. One hundred and five patients were included in the study, (44 males and 61 females, median age 21 [15-25] years), 51 in the cefaclor group and 54 in the no cefaclor group. After treatment, the PLI, GI, and SBI scores in the two groups were higher than those before treatment, and the levels of serum inflammatory markers significantly increased (p < 0.05). After treatment, the PLI, GI, and SBI scores in the test group were significantly lower than those in the control group (p < 0.001). The levels of serum interleukin-1β, interleukin-6, interleukin-8, and tumor necrosis factor-α were significantly lower in the test group, and the interleukin-2 level was higher in the test group (p < 0.001). There was no significant difference in the incidence of complications between the two groups (p > 0.05). Cefaclor and micro-implant anchorage have a good clinical effect on orthodontics in patients with periodontitis, improving periodontal health and reducing inflammatory response.

Efficacy of Xuebijing injection for the treatment of acute lung injury: A meta-analysis of randomized controlled trials

BackgroundManagement guidelines for acute lung injury (ALI) are extremely limited. Xuebijing, a traditional Chinese medicine, exerts therapeutic effects in patients with ALI; however, supportive evidence is currently insufficient. Material and methodsA systematic literature search of seven electronic databases for randomised controlled trials assessing the efficacy of Xuebijing injections in patients with ALI, published from inception to March 31, 2024, was performed. The Risk of Bias assessment tool recommended by The Cochrane Collaboration was used for quality evaluation. Review Manager version 5.3 (R Foundation for Statistical Computing, Vienna, Austria) was used for analysis. Dichotomous variables are expressed as relative risk (RR) and continuous variables as standardised mean difference (SMD). Heterogeneity was assessed using the I2 statistic and a funnel plot was used to visually assess publication bias. ResultsSixteen studies comprising 1327 patients were included. Xuebijing injection improved oxygenation index (SMD 1.08 [95 % confidence interval (CI) 0.79–1.38]), reduced the incidence of acute respiratory distress syndrome (RR 0.56 [95 % CI 0.42–0.74) and all-cause mortality (RR 0.48 [95 % CI 0.34–0.67]), and decreased serum tumor necrosis factor-alpha (SMD -1.33 [95 % CI -1.50 to −1.17]) and interleukin-6 levels (SMD -1.35 [95 % CI -1.52 to −1.17]). The funnel plot indicated no publication bias. ConclusionXuebijing injection may be an effective treatment for ALI. However, this needs to be further confirmed in well-designed, large-sample, randomised controlled trials.

Effects of different doses of dexmedetomidine combined with sufentanil in intravenous controlled analgesia after Salter osteotomy in children.

This study aimed to investigate the effect of different doses of dexmedetomidine combined with sufentanil on postoperative analgesia in developmental hip dislocation in children after Salter osteotomy. The clinical data of 98 children with developmental hip dislocation, who underwent Salter osteotomy in our center between January 2020 and February 2023, were selected. The children were randomly divided into four groups based on the application of patient-controlled intravenous analgesia (sufentanil + granisetron ± dexmedetomidine). All children received 1 µg/kg/day of sufentanil and 3 mg of granisetron. Group A did not receive dexmedetomidine, and Groups B, C, and D received 0.5, 0.75, and 1.0 µg/kg/day of dexmedetomidine, respectively. The pain indicators and immune factor levels of children in each group were compared. The heart rate (HR) and respiratory rate (RR) 2 h after operation in Groups C and D were significantly lower than those in Groups A and B (P < 0.05). The pain scores decreased over time after treatment in all groups. When compared at the same time point, children in Group D had the lowest pain scores, which were significantly lower than the other three groups (P < 0.05). The total consumption of sufentanil in Groups C and D was significantly lower than that in Group A (P < 0.05). On the first day after surgery, the children in Group D had lower levels of serum adrenocorticotropic hormone, interleukin-6, and corticosterone than those in Group A (P < 0.05). Administration of 1.0 µg/kg/day of dexmedetomidine combined with sufentanil in intravenous controlled analgesia after Salter osteotomy for developmental hip dislocation in children has a better analgesic effect, less consumption of sufentanil, and low incidence of opioid adverse reactions.

Sishen Pill inhibits intestinal inflammation in diarrhea mice via regulating kidney-intestinal bacteria-metabolic pathway.

Sishen Pill (SSP) has good efficacy in diarrhea with deficiency kidney-yang syndrome (DKYS), but the mechanism of efficacy involving intestinal microecology has not been elucidated. This study investigated the mechanism of SSP in regulating intestinal microecology in diarrhea with DKYS. Adenine combined with Folium sennae was used to construct a mouse model of diarrhea with DKYS and administered with SSP. The behavioral changes and characteristics of gut content microbiota and short-chain fatty acids (SCFAs) of mice were analyzed to explore the potential association between the characteristic bacteria, SCFAs, intestinal inflammatory and kidney function-related indicators. After SSP intervention, the body weight and anal temperature of diarrhea with DKYS gradually recovered and approached the normal level. Lactobacillus johnsonii was significantly enriched, and propionic, butyric, isobutyric and isovaleric acids were elevated. Serum creatinine (Cr), interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) levels of the mice were reduced, while serum blood urea nitrogen (BUN) and secretory immunoglobulin A (sIgA) in the colonic tissues were increased. Moreover, there were correlations between L. johnsonii, SCFAs, intestinal inflammatory, and kidney function. SSP might suppress the intestinal inflammation by regulating the "L. johnsonii-propionic acid" pathway, thus achieving the effect of treating diarrhea with DKYS.

Dietary Bacillus velezensis KNF-209 supplementation improves growth performance, enhances immunity, and promotes gut health in broilers

This study aimed to investigate the effects of dietary Bacillus velezensis KNF-209 (BV-KNF-209) on the growth performance, immunity, and gut health of broilers. A total of 540 one-day-old male Cobb-500 broilers were randomly divided into 5 groups of 6 replicates with 18 broilers per replicate. Dietary treatments were corn-soybean meal basal diets supplemented with 0, 50, 100, 200, and 400 mg/kg BV-KNF-209 (CON, BV 50, BV 100, BV 200, and BV 400 groups, respectively) for 42 d. Compared with the CON group, the average daily gains (ADG) at 0 to 42 d in the BV 100 and BV 200 groups were significantly increased (P < 0.01), and the feed-to-gain (F:G) ratios were significantly decreased at 0 to 21 d (P < 0.01) and 0 to 42 d (P < 0.05). The BV 200 and BV 400 groups had higher serum immunoglobulin M (IgM) levels at d 21 and 42 (P < 0.05). The serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) were significantly decreased in the BV 50, BV 100, and BV 200 groups at d 21 (P < 0.05), and serum IL-1β and IL-6 levels were also reduced in the BV 100 and BV 200 groups at d 42 (P < 0.05). Meanwhile, increased interleukin-10 (IL-10) levels in the jejunal and ileal mucosa at d 42 were observed in the BV 100, BV 200, and BV 400 groups (P < 0.05), while the IL-1β and IL-6 levels (P < 0.01) were decreased. The BV 200 and BV 400 groups showed significantly higher activities of lipase and trypsin (P < 0.05) in jejunal digesta as well as higher activities of amylase and trypsin (P < 0.01) in ileal digesta at d 42. The cecal acetic acid and propionic acid levels in the BV groups and lactic acid levels in the BV 50, BV 100, and BV 200 groups (P < 0.05) were significantly higher compared to those in the CON group. Overall, dietary BV-KNF-209 supplementation significantly improved broiler growth performance, an effect that may have been achieved by heightening immunity, increasing digestive enzyme activity, and raising intestinal short-chain fatty acids and lactic acid levels.

Inflammatory biomarkers and frailty transitions in older adults with cancer: Findings from a national cohort study.

e13772 Background: Approximately 67% of cancer survivors were aged 65 or older in the U.S.; they face a heightened risk of frailty, as both cancer and anti-cancer treatment impose additional stressors on the older adults’ physiological reserves. Inflammatory biomarkers such as serum C-reactive protein (CRP) and Interleukin-6 (IL-6) levels were associated with frailty. However, the role of inflammatory biomarkers on the transitions of frailty states remains unclear. This study aimed to describe transitions between frailty states and death and quantify the predictive effect of inflammatory biomarkers on transitions. Methods: We used data from the National Health and Aging Trends Study (NHATS) from 2017 to 2022. A total of 1,219 older cancer survivors (&gt;67 years) were included. Frailty was assessed annually using the Fried Frailty Phenotype (exhaustion, low physical activity, shrinking, low walking speed, and weakness) to categorize participants as “non-frail,” “pre-frail,” and “frail.” Inflammatory biomarkers were obtained via dried blood spots at baseline (2017). Plasma-equivalent values of CRP and IL-6 were used. Covariates included sex, age category, race, education level, marital status, obesity, and number of comorbidities. We defined four states that included three frailty states (non-frail, pre-frail, and frail) and an absorbing state of death. The multi-state Markov models were performed to capture possible transitions between frailty states and examine the effect of CRP and IL-6 on the five main transitions between states (non-frail to pre-frail, pre-frail to non-frail, pre-frail to frail, frail to pre-frail, frail to death). Results: At baseline, 25.27% were non-frail, 52.34% were pre-frail, and 22.40% were frail. During the follow-up time of 5 years, 1,396 transitions were observed, with 950 (68.05%) progressions (or to death) and 446 (31.95%) reversals. For participants who were non-frail, they were highly likely to develop pre-frailty (transition intensity=0.63). For participants with pre-frailty, progression to frailty was a little more likely than recovery to non-frailty (0.25 vs 0.21). Once entering the frail state, the likelihood of death outweighed that of recovery (0.30 vs 0.28). A higher level of CRP or IL-6 was associated with frailty progression (non-frail to pre-frail and frail to death), while a lower level of CRP or IL-6 was associated with recovery of frailty (pre-frail to non-frail and frail to pre-frail). Conclusions: This study is the first to investigate the longitudinal relationship between inflammatory biomarkers and frailty transitions in older cancer survivors using a nationally representative survey dataset. Our findings outlined potential transitions between frailty states and death, highlighting the role of elevated serum CRP and IL-6 levels on the increased risk of frailty progression and reduced risk of frailty recovery over 5 years.

I-FABP protein/mRNA and IL-6 as biomarkers of intestinal barrier dysfunction in neonates with necrotizing enterocolitis and SPF BALB/c mouse models.

Neonatal necrotizing enterocolitis (NEC) is a serious intestinal inflammatory disease. We investigated intestinal fatty acid binding protein (I-FABP), I-FABP mRNA, and interleukin-6 (IL-6) as potential diagnostic biomarkers in NEC. Forty mice were subjected to hypoxic-ischemic intestinal injury, and then serum I-FABP protein and mRNA levels were quantified. Ileal tissue pathological scores were determined by hematoxylin and eosin staining. I-FABP expression levels and translocation in these tissues were detected using western blotting and immunofluorescence, respectively. Samples from 30 human neonates with NEC and 30 healthy neonates had serum I-FABP protein/mRNA and IL-6 levels measured. The mouse ileal tissue pathological score and I-FABP levels, as well as serum I-FABP and I-FABP mRNA levels, were significantly higher in the model group than in the control group. Serum I-FABP, I-FABP mRNA, and IL-6 levels were significantly higher in human neonates with NEC than in the healthy group. Logistic regression and receiver operating curve analyses revealed that I-FABP protein/mRNA and IL-6 levels could be diagnostic biomarkers for NEC. I-FABP protein/mRNA and IL-6 levels are useful biomarkers of intestinal ischemic injury in neonates with NEC. The combined detection of I-FABP protein/mRNA and IL-6 is recommended rather than using a single biomarker.

Role of celecoxib in reducing cognitive impairment in patients receiving definitive chemoradiation for head and neck carcinoma: A phase II randomized placebo controlled trial (CELCI-HN study).

TPS12150 Background: Head and neck squamous cell carcinoma (HNSCC) is common in the Indian subcontinent and majority (65%) patients present in an advanced stage. Chemotherapy related cognitive impairment (CRCI) is a poorly defined and underestimated phenomenon in the HNSCC population. Through this study, we are attempting to establish evidence of activity of agents targeting neuro-inflammation in reducing or halting cognitive decline associated with definitive chemoradiotherapy for head and neck malignancies without adding to treatment-associated toxicity. This study can potentially aid in developing a cost effective approach with a readily available and cheap agent like celecoxib in improving the quality of life in this cohort of patients. Methods: This is a single center, double blinded placebo controlled phase 2 randomized trial. We intend to randomize 92 non metastatic HNSCC patients registered at a large tertiary cancer center of North India {Department of Medical Oncology (Head and Neck Cancer Clinic, All India Institute of Medical Sciences-National Cancer Institute, India)} planned for definitive chemoradiation (CTRT) with or without induction chemotherapy. Patients in the experimental arm will receive celecoxib 100 mg or matched placebo tablet orally twice a day starting with day 1 of initiation of definitive chemoradiotherapy/induction chemotherapy for a duration of 6 months or until unacceptable toxicity. Our primary objective is to determine the activity of celecoxib versus placebo in reducing cognitive decline in patients undergoing definitive CTRT with or without induction chemotherapy in HNSCC through patient reported outcome tools (FACT cog questionnaire). Secondary objectives include assessment of adverse event profile (measured using CTCAE v5.0), objective assessment of neurocognitive decline using neuropsychological battery of tests, to identify predictors of cognitive decline on the basis of site of malignancy, radiation dose to the base of skull and brainstem, age, comorbidities and educational status. Tertiary objective include evaluation of inflammatory biomarkers e.g serum COX-2, serum Interleukin and tumor necrosis factors-alpha levels at the end of therapy and on follow up.

Changes in Levels of Serum Cytokines and Chemokines in Perforated Appendicitis in Children.

Appendicitis is primarily diagnosed based on intraoperative or histopathological findings, and few studies have explored pre-operative markers of a perforated appendix. This study aimed to identify systemic biomarkers to predict pediatric appendicitis at various time points. The study group comprised pediatric patients with clinically suspected appendicitis between 2016 and 2019. Pre-surgical serum interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), intercellular cell-adhesion molecule-1 (ICAM-1), and endothelial selectin (E-selectin) levels were tested from day 1 to day 3 of the disease course. The biomarker values were analyzed and compared between children with normal appendices and appendicitis and those with perforated appendicitis (PA) and non-perforated appendicitis. Among 226 pediatric patients, 106 had non-perforated appendicitis, 102 had PA, and 18 had normal appendices. The levels of all serum proinflammatory biomarkers were elevated in children with acute appendicitis compared with those in children with normal appendices. In addition, the serum IL-6 and TNF-α levels in children with PA were significantly higher, with an elevation in TNF-α levels from days 1 and 2. In addition, serum IL-6 levels increased significantly from days 2 and 3 (both p < 0.05). Serum ICAM-1 and E-selectin levels were elevated in the PA group, with consistently elevated levels within the first three days of admission (all p < 0.05). These results indicate that increased serum levels of proinflammatory biomarkers including IL-6, TNF-α, ICAM-1, and E-selectin could be used as parameters in the prediction and early diagnosis of acute appendicitis, especially in children with PA.

The results of clinical monitoring of phytotherapeutic correction in the presence of benign breast diseases

Benign breast diseases (BBDs) are the most common group of diseases among women that negatively affect their quality of life. In fact, these pathological conditions are diagnosed at least 10 times more often than breast cancer. Up to 30% of women with BBDs will need treatment at some point in their lives. A triple assessment which is performed using imaging methods of clinical examination (ultrasound examination, mammography) and histopathological examination after a puncture biopsy during the initial consultation allows to exclude breast cancer in the majority of patients. `The main clinical manifestation of BBDs is mastalgia. In recent years, a variety of natural herbal remedies have played a significant role in the symptom-modifying therapy of mastalgia.The objective: to study the possibility of using an innovative phytocomplex as a symptom-modifying agent in the presence of BBDs, which is manifested by mastalgia.Materials and methods. Clinical monitoring of 60 patients between the ages of 22 and 46 years old with BBDs of various genesis was carried out. The study group included 30 women who used a phytocomplex containing 3,3`-diindolylmethane (200 mg), vitex extract (100 mg), epigallocatechin (45 mg), broccoli extract (0.4 mg), 1 tablet twice daily for 90 days. The reference group included 30 women who used a dietary supplement with indole-3-carbinol (200 mg) according to a similar scheme.Assessment of clinical symptoms of BBDs, measurement of interleukin-6 level in blood serum, fine-needle aspiration biopsy of pathological foci and immunocytochemical analysis of biopsies, assessment of patients’ quality of life were performed before and after treatment.Results. The innovative phytocomplex (diindolylmethane – DIM, Agni casti fructus) compared to the indole-3-carbinol monopreparation demonstrated a higher efficiency in creating conditions for the elimination of clinical manifestations of BBDs: discomfort, swelling, pain at rest and during palpation.A pronounced regression of clinical symptoms was observed in the study group: a decreased frequency of patients with chest discomfort from 100 to 36.7%, a decrease in pain at rest and during pressure – from 53.3 to 13.3% and from 33.3 to 13.3%, respectively, swelling – from 46.7 to 16.7%. The index of the quality of life of patients, which was determined by the sum of the scores of the questionnaire filled out by the patients themselves, showed a more pronounced tendency to increase in the study group.Conclusions. The innovative phytocomplex can be recommended as a preparation for phytotherapeutic correction in order to help reduce the intensity and eliminate mastalgia and other symptoms of BBDs.

Effect of ADSCs on Th17/Treg and T-bet/GATA-3 in model mice with primary immune thrombocytopenia.

We aimed to observe the effects of adipose-derived mesenchymal stem cells (ADSCs) on T helper 17 (Th17)/regulatory T cells (Treg) and T-box transcription factor (T-bet)/GATA-binding protein 3 (GATA-3) in model mice with primary immune thrombocytopenia (ITP). 32 BALB/C mice were selected. ADSCs were isolated from 2 mice and cultured. The other 30 mice were randomly divided into the normal control group, the ITP model control group, and the ITP experimental group. Platelet count (PLT), Th17/Treg cells, related serum cytokines [interleukin-6 (IL-6), IL-17A, IL-10, and transforming growth factor β1 (TGF-β1)], T-bet and GATA-3 mRNA levels in peripheral blood mononuclear cells (PBMCs) in the 3 groups were detected. PLT and Treg in the ITP experimental group were significantly lower than those in the normal control group (P<0.05), but significantly higher than those in the ITP model control group (P<0.05). Th17 and Th17/Treg in the ITP experimental group were significantly higher than those in the normal control group (P<0.05), but significantly lower than those in the ITP model control group (P<0.05). Serum IL-6 and IL-17A levels, and T-bet mRNA levels in the ITP experimental group were significantly higher than those in the normal control group (P<0.05), but significantly lower than those in the ITP model control group (P<0.05). Serum IL-10 and TGF-β levels, and GATA-3 mRNA levels in the ITP experimental group were significantly lower than those in the normal control group (P<0.05), but significantly higher than those in the ITP model control group (P<0.05). ADSCs can effectively regulate Th17/Treg balance and improve T-bet/GATA-3 mRNA expression levels in ITP model mice.

Efficacy and prognostic value of peripheral blood CD4+ T cells and serum IL-6 and IL-8 in tuberculous meningitis

ObjectiveTo investigate the value of peripheral blood clusters of differentiation 4 (CD4+) T-lymphocyte (T cells) count and serum interleukin-6 (IL-6) and interleukin-8 (IL-8) in the treatment and prognosis of tuberculous meningitis (TBM). MethodsSixty-five patients with TBM were prospectively included in the observation group. Sixty-five patients with pulmonary TB and a group of 65 healthy individuals served as the control groups. The differences in peripheral blood CD4+ T-cell count, serum IL-6, and IL-8 levels were compared, and changes in these indices after anti-TB treatment in the observation group were analysed. The observation group was divided into effective and ineffective groups based on their response after 24 weeks of anti-TB treatment. The study also evaluated the influence of peripheral blood CD4+ T-cell count, serum IL-6, and IL-8 levels on the adverse prognosis of TBM during anti-TB treatment. ResultsBefore treatment, the CD4+ T-cell count in the peripheral blood of the observation group was lower than in both the control and healthy groups, and serum IL-6 and IL-8 levels were higher than in the control group (P < 0.001). After 24 weeks of anti-TB treatment, the CD4+ T-cell count in the peripheral blood of the observation group increased, whereas the levels of IL-6 and IL-8 decreased significantly (P < 0.001). The levels of CD4+ T cells and IL-6 in the peripheral blood of patients before treatment were identified as independent factors influencing the efficacy of anti-TB treatment (odds ratio [OR] = 0.989, 95 % confidence interval [CI]: 0.980–0.997; OR = 1.010, 95 % CI: 1.003–1.017). ConclusionIn patients with TBM, the CD4+ T-cell count in the peripheral blood is decreased, whereas serum IL-6 and IL-8 are increased. The combination of CD4+ T cells and IL-8 shows a degree of predictive value for the prognosis of anti-TB treatment.

Effects of Sacha Inchi (Plukenetia volubilis) Oil on Serum Interleukin 6 Levels and Foam Cell Count in Male Wistar Rats (Rattus norvegicus) Fed a High Fat and Fructose Diet

A high-fat, high-fructose diet induces pro-inflammatory agents such as Interleukin-6 (IL-6) and hyperlipidemia, leading to atherosclerosis. Sacha inchi oil, rich in alpha-linolenic acid (ALA), has anti-inflammatory and lipid-modulating properties. This study aimed to examine the effect of sacha inchi oil on serum IL-6 levels and foam cell count in the aorta of wistar rats on a high-fat, high-fructose diet. This experiment is a true experimental study with a post-test-only control group design, 30 male wistar rats were divided into five groups: normal control (K0), high fat and fructose diet (HFFD) (K1), and three treatment groups receiving HFFD with sacha inchi oil at doses of 0.27 ml/200gBW/day (P1), 0.54 ml/200gBW/day (P2), and 1.08 ml/200gBW/day (P3) for 28 days. On day 29, serum IL-6 levels were measured using ELISA. Mean serum IL-6 levels were K1 (8.465 ng/L), P1 (4.294 ng/L), P2 (3.197 ng/L), P3 (1.379 ng/L), and K0 (1.340 ng/L), with significant differences among groups (p&lt;0.05) except between K0 and P3 (p&gt;0.05). Mean foam cell counts were K1 (55.3 cells/fov), P1 (47.1 cells/fov), P2 (53.2 cells/fov), P3 (52.6 cells/fov), and K0 (44.4 cells/fov), with significant differences between K0 and K1, K1 and P1, K0 and P2, and K0 and P3 (p&lt;0.05). Sacha inchi oil significantly reduced IL-6 levels at all doses compared to the negative control (p&lt;0.05), with the 1.08 ml/200 g/day dose being most effective. The 0.27 ml/200 g/day dose inhibited foam cell formation in HFFD rat. In conclusion, sacha inchi oil reduces serum IL-6 levels and inhibits foam cell formation in male wistar rats on a high-fat, high-fructose diet.

Levels of IL-6 and IL-8 in Complicated versus Uncomplicated Urinary Tract Infection

Urinary tract infections (UTIs) are one of the world's most frequent infectious diseases, affecting 150 million people each year and resulting in severe morbidity and high medical expenditures. UTIs can be clinically defined as uncomplicated UTIs (uUTIs) or complicated UTIs (cUTIs) to differentiate infections of benign origin from those with a higher risk of recurrence or progression to severe pathology. The aim of this study was to evaluate interleukin-6 (IL-6) and IL-8 as potential biomarkers in differentiating complicated and uncomplicated. Ninety samples of urine were collected. There were 43 samples from healthy controls and 47 samples from UTI patients—those who have been clinically diagnosed with UTIs by the urologist. The serum IL-6 and IL-8 were measured using an enzyme-linked immunosorbent assay and commercially available kits. The levels of both IL-6 and IL-8 were significantly higher in UTI patient then in control subjects (p=0.001, p=0.001). A significant difference was observed in the mean of level IL-6 between culture positive UTI patients and culture negative UTI patients (p=0.014). In addition, the type of bacterial growth, a significant difference was observed in the mean of serum IL-6 and IL-8 level in UTI caused by gram negative bacteria in comparison with UTI caused by gram positive bacteria. High levels of IL-6 are associated with the growth of gram-negative bacteria, and this indicates that gram-negative bacteria could induce stronger inflammatory responses than gram-positive bacteria. IL-8 levels are higher in UTIs caused by gram-negative bacteria. This result further supported the evidence that gram-negative bacteria are potent inducers of inflammatory responses.

Value of exhaled hydrogen sulfide in early diagnosis of esophagogastric junction adenocarcinoma.

Esophagogastric junction adenocarcinoma (EJA) has increased in recent years, and it exhibits a poor prognosis and a short survival period for patients. Hydrogen sulfide (H2S) plays an important role in the pathogenesis of cancer and has been studied as a diagnostic factor in some tumor diseases. However, few studies have explored the diagnostic value of H2S for EJA. In the present study, a total of 56 patients with early-stage EJA were enrolled while 57 healthy individuals were selected as the healthy control group. Clinical features were recorded, and exhaled H2S and blood samples were collected from both groups. Exhaled H2S and serum interleukin-8 (IL-8) expression levels were detected in both groups. The correlation between exhaled H2S and serum IL-8 levels was analyzed using Pearson's correlation method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of exhaled H2S combined with IL-8 detection in EJA. The results showed that patients with EJA exhaled more H2S than healthy individuals. In addition, exhaled H2S was positively correlated with increased IL-8 expression. The ROC curve revealed that the exhaled H2S test had an acceptable diagnostic effect and could be used to diagnose EJA. The increase in H2S exhaled by patients with EJA indicated that H2S may be related to the occurrence and development of EJA; however, the in vivo mechanism needs to be further explored. Collectively, it was determined in the present study that exhaled H2S was significantly higher in patients with early-stage EJA than in healthy controls and combined diagnosis with patient serum IL-8 could improve diagnostic accuracy, which has potential diagnostic value for early diagnosis and screening of EJA.

Amygdalin ameliorates alopecia areata on C3H/HeJ mice by inhibiting inflammation through JAK2/STAT3 pathway

BackgroundEvidence has demonstrated that Chinese medicine formula Xuefu Zhuyu decoction can markedly promote the formation of new hair in patients and mice with alopecia areata (AA). Amygdalin is one of the active components of Xuefu Zhuyu decoction, but its therapeutic effects and the underlying mechanisms on AA remains largely unrevealed. PurposeTherefore, this study aims to investigate the therapeutic effects and to probe its molecular mechanisms of inflammation and immune regulation on AA model of C3H/HeJ mice. Study designThe C3H/HeJ female mice were divided into control, AA, rusolitinib (60 mg/kg), and amygdalin groups (60, 90, and 120 mg/kg, 0.2 ml/10 g, i.g.). MethodsThe optical microscope was used to observe the feature of the local skin, and the number of lanugo and terminal hair. H&E staining was performed to determine the degree of pathological damage to the skin. ELISA was performed to detect levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in mice serum. Flow cytometry was carried out to analyze the CD4+CD25+FOXP3+, CD4+ and CD8+ of skin tissue. And the levels of CD4+ and CD8+, p-JAK/JAK2, p-STAT3/STAT, and SOCS3 were detected by immunohistochemistry. Western blot and qRT-PCR were employed to examine the expression levels of IL-6, TNF-α, IFN-γ, JAK2, p-JAK, STAT, p-STAT3 and SOCS3 proteins and genes in skin tissues. ResultsCompared with AA group, amygdalin immensely increased the number of vellus hairs and decreased the number of terminal hairs determined by skin microscopy and H&E staining. ELISA, Western blot and qRT-PCR data showed that the levels of IL-6, TNF-α and IFN-γ in serum and skin tissues of AA mice were significantly increased, while amygdalin administration dramatically restrained the contents of the three pro-inflammatory factors. Flow cytometry and immunohistochemistry hinted that amygdalin observably enhanced the number of CD4+CD25+FOXP3+ and CD4+ cells, while inhibited the number of CD8+ positive cells in mice with AA. Moreover, amygdalin signally reduced JAK2/STAT3 pathway-related protein and gene levels in AA mice. ConclusionAmygdalin could inhibit inflammatory response and improve immune function in the treatment of AA. The underlying molecular mechanism may be related to inhibition of JAK2/STAT3 pathway.

Correlation of serum interleukin-8 levels and prostate volume to the degree of lower urinary tract symptoms in patients with benign prostate enlargement: a cross-sectional study

BackgroundBenign prostatic enlargement (BPE) and lower urinary tract symptoms (LUTS) are pro-inflammatory cytokine interleukin-8 (IL-8)-associated which causes epithelial hyperplasia of the prostate transitional zone. This study aimed to determine the correlation between the levels of IL-8 serum and the prostate volume with the degree of LUTS severity in patients with BPE.MethodsDetermination of the correlation between serum IL-8 levels and prostate volume with the LUTS severity degree was conducted using a cross-sectional approach. The International Prostate Symptom Score was used to measure the LUTS severity degree, the enzyme-linked immunosorbent assay (ELISA) technique was used to measure the serum IL-8 level, and the transabdominal ultrasonography (TAUS) was used to measure the prostate volume. The sample used in this study was 32 patients with BPE grouped by the degree of LUTS severity of the patients. The correlation between variables was then analyzed using the Pearson correlation test.ResultsThe prostate volume was higher in severe LUTS degree (38.19 cc) than in the mild LUTS degree (13.05 cc). The levels of serum IL-8 were higher in the severe LUTS degree (21.65 pg/mL) than in the mild LUTS degree (8.44 pg/m). Both the levels of serum IL-8 and the degree of LUTS did not have a significant correlation with the volume of prostate (p > 0.05). On the other side, the prostate volume and the degree of LUTS severity had a significant positive correlation (p = 0.001, R = 0.913).ConclusionThe prostate volume and the levels of serum IL-8 are higher in the severe LUTS degree. There is a trend of increasing prostate volume with the severity of LUTS symptoms and higher serum IL-8 levels. The severity of prostate enlargement can be assessed by measuring the levels of IL-8 in the serum.

The influence of occupational heat stress on serum inflammatory cytokines among traditional bakery workers in Iran.

Heat exposure exceeding the ISO7243:1989 standard limit can contribute to health problems among employees in a variety of workplaces. Ignoring heat standard requirements in hot working conditions such as bakeries results in physiologic and health problems, as well as an elevated risk of later illnesses. In this analytical case-control study, the serum levels of four inflammatory factors (interleukin-1 beta, interleukin-6, tumor necrosis factor-α, and C-reactive protein) were assessed using an enzyme-linked immunosorbent assay. 105 male artisan bakers (in four job classifications in bakeries and staff) were compared based on demographic characteristics and inflammatory factors. The findings of the study showed correlations between serum interleukin-1β, interleukin-6, and C-reactive protein levels and thermal exposure in the occupational environment and employment type. Moreover, some differences in serum level of interleukin-1β and job type were observed. Heat overexposure affected the increase of interleukin-1β and C-reactive protein secretion. As a result of years of working in high-temperature conditions, inflammation can lead to subsequent diseases in workers. To protect their health from this occupational hazard, additional safeguards are needed. Our recommendations could also be applied to overly hot work environments that may cause heat stress in workers.
