Interleukin-6 Levels In Patients Research Articles

Salivary interleukin-17A and interleukin-18 levels in patients with celiac disease and periodontitis

Background An increased level of interleukin-17A and interleukin-18 in the serum and intestinal mucosa of celiac disease patients reflecting the severity of villous atrophy and inflammation was documented. Thus, the objective of this study was to evaluate the concentrations of salivary-17A, interleukin-1 beta, and interleukin-18 in patients with celiac disease who are on a gluten-free diet, both with and without periodontitis, and to compare these levels with those in healthy individuals. Methods The study involved 23 participants with serologically confirmed celiac disease (CD) and 23 control subjects. The CD patients had been following a gluten-free diet (GFD) for a minimum of 1 year and had no other autoimmune disorders. The research involved collecting demographic data, conducting periodontal examinations, gathering unstimulated whole saliva, and performing enzyme-linked immunosorbent assays to measure salivary interleukin-17A, interleukin-1 beta, and interleukin-18 levels. Spearman’s correlation analysis was utilized to explore the relationships between CD markers in patients on a GFD and their periodontal clinical findings. Results The periodontal findings indicated significantly lower values in celiac disease patients adhering to a gluten-free diet compared to control subjects (p = 0.001). No significant differences were found in salivary IL-17A, IL-18, and IL-1B levels between celiac disease patients and control subjects. Nevertheless, the levels of all interleukins were elevated in periodontitis patients in both the celiac and control groups. The IL-1 Beta level was significantly higher in periodontitis patients compared to non-periodontitis patients in the control group (p = 0.035). Significant negative correlations were observed between serum IgA levels and plaque index (r = −0.460, p = 0.010), as well as gingival index (r = −0.396, p = 0.030) in CD patients on a gluten-free diet. Conclusion Celiac disease patients on gluten-free diet exhibited better periodontal health compared to control subjects. However, increased levels of salivary IL-17A, IL-18 and IL-1B levels were associated with periodontitis. Additionally, serum IgA level was significantly inversely associated with periodontitis clinical manifestations and with salivary inflammatory mediators in CD patients on GFD.

Interleukin6 level in patients admitted with fever for evaluation in a tertiary infectious disease hospital

Interleukin6 level in patients admitted with fever for evaluation in a tertiary infectious disease hospital

Diagnostic and Prognostic Value of Pentraxin 3, Interleukin-6, CRP, and Procalcitonin Levels in Patients with Sepsis and Septic Shock.

In this prospective study, we aim to evaluate the effects of antibiotherapy on pentraxin-3 (PTX3), C-reactive protein (CRP), and interleukin-6 (IL-6) levels in patients with sepsis and septic shock. In our study, CRP, procalcitonin, IL-6, and PTX3 levels at initial and 48 hours of the antibiotherapy of patients who were admitted to the pediatric intensive care unit (PICU) with the diagnosis of sepsis and septic shock between June 2020 and March 2021 were compared. Patients were compared with the age-appropriate case-control group formed from the patients who received pre-operative routines to investigate the diagnostic value. CRP, IL-6, and PTX3 levels of the patients were significantly higher compared to controls (P < 0.05). After the 48th hour of treatment compared to initial CRP, lactate and PCT levels were significantly lower (P < 0.05). The IL-6 and PCT levels were significantly higher in patients with mortality than in surviving patients. Surviving patients showed a significant decrease in CRP level at the 48th hour. IL-6 levels of patients with septic shock were significantly higher than those with sepsis (P = 0.010; P < 0.05). In the diagnosis of septic shock, the area under curve was 0.785 for IL-6 and the standard deviation was 0.09 (P = 0.002, cut-off value, >32 pg/mL, 88.9% sensitivity, 65.6% specifity). The results of this study indicated that IL-6 level is an appropriate biomarker with high specificity in the diagnosis of sepsis and septic shock and in evaluating the response to treatment and determining the prognosis.

TNF-alpha and IL-10 Levels in Iraqi PCOS and Non-PCOS Patients Undergoing ICSI: An Immunological Perspective

Background: Essential cytokines like tumor necrosis factor-alpha (TNF-α) and interleukin-10 (IL-10) play a critical role in immune regulation, particularly in conditions like polycystic ovary syndrome (PCOS). Objective: To compare TNF-α and IL-10 levels in patients with and without PCOS undergoing intracytoplasmic sperm injection (ICSI) and their effects on ICSI. outcome Methods: This study involved a cohort of 125 patients undergoing ICSI, divided into two groups: those identified with PCOS according to Rotterdam criteria (n=65) and those without PCOS (n=60). The ELIZA method was used to measure the levels of TNF-α and IL-10 in the blood in order to see if they were related to PCOS and to look into a possible connection between these cytokines and the outcome of the ICSI. Results: Significant differences were found in the serum levels of TNF-α and IL-10 between the two groups, suggesting a distinct immunological profile in PCOS patients undergoing fertility treatment. There is no significant correlation between these cytokines and the total number of retrieved oocytes, oocyte maturity, fertilization rate, or pregnancy rate. Conclusions: The study revealed notable differences in serum TNF-α and IL-10 levels between PCOS and non-PCOS groups, suggesting a unique immunological profile in PCOS patients undergoing fertility treatments. Both cytokines did not significantly correlate with the total number of retrieved oocytes, oocyte maturity, fertilization rate, or pregnancy rate. Other factors might be more influential in determining crucial fertility outcomes.

Elevated Salivary IL-8 Levels in Patients with Aphthous Ulceration and Rheumatoid Arthritis: A Cross-Sectional Study

Background: Aphthous ulcers (AU) and Rheumatoid Arthritis (RA) are conditions marked by inflammation, with Interleukin 8 (IL-8) playing a significant role in their pathogenesis. This study aims to evaluate the levels of IL-8 in saliva among individuals with AU, RA, both conditions and healthy controls, providing insights into its potential as a diagnostic biomarker and therapeutic target. Methods: The study, endorsed by the Ethics Committee of the University of Kufa, College of Dentistry, Department of Oral Pathology, employed a descriptive, analytical, and cross-sectional approach. Participants included patients with AU, RA, both conditions and a control group, totalling 94 individuals. Exclusion criteria encompassed medication use, other systemic conditions, and lifestyle factors like smoking. Saliva and blood samples were collected for IL-8 concentration measurement using ELISA and for Rheumatoid Factor (RF) and anti-CCP analysis. Results: Analysis showed the highest average salivary IL-8 levels in patients with both AU and RA (483.33 ± 141.20 pg/mL), followed by the RA group (338.57 ± 79.11 pg/mL), the AU group (381 ± 108.48 pg/mL), and the control group (213.69 ± 84.65 pg/mL). Significant differences in IL-8 levels were observed between these groups, with the combined AU and RA groups showing the highest concentrations. However, the variation in IL-8 levels between those who have both AU and RA and those with only RA was not statistically significant. Conclusion: The study highlights a distinct elevation in salivary IL-8 levels in patients with AU and RA, particularly in those suffering from both conditions.

Interleukin 6 Levels and Disease Activity in Takayasu Arteritis: A Systematic Review With Meta-analysis.

Various studies have suggested interleukin 6 (IL-6) as a potential biomarker for detecting disease activity in Takayasu arteritis. A systematic review and meta-analysis was performed to assess differences in IL-6 levels in patients with active (aTA) and inactive Takayasu arteritis (iTA), as well as healthy controls (HCs), using validated activity scores. Study quality and the risk of bias were assessed using STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) and the Newcastle-Ottawa and Joanna Briggs checklist, respectively. For the meta-analysis, we pooled the raw mean IL-6 levels in each group and then estimated and pooled the crude mean differences between the groups. We applied a random-effects model in all analyses. Of the 93 eligible articles, 10 were included after removing duplicates and studies that met the exclusion criteria. Overall, 1825 patients with a mean age ranging from 24 to 40.6 years were included. The pooled levels of IL-6 increased depending on disease activity as follows: HCs: 3.08 (95% confidence interval [CI], 0.88-5.28), iTA: 7.21 (3.61-10.82), and aTA: 22.67 (12.44-32.91) pg/mL. Patients with aTA had higher IL-6 levels than HCs (21.52 [95% CI, -0.43 to 43.47]) and those with iTA (16.69 [95% CI, 5.32-28.06]), whereas IL-6 levels were not different between HCs and patients with iTA (3.62 [95% CI, -13.18 to 20.42]). Interleukin 6 levels are significantly increased in patients with aTA compared with those with iTA and HCs but not in patients with iTA compared with HCs. More studies are needed to establish the IL-6 cutoff value for assessing disease activity.

The effect of inflammation markers on cortical thinning in major depressive disorder: A possible mediator of depression and cortical changes

BackgroundMajor depressive disorder (MDD) is a prevalent mental health condition with significant societal impact. Owing to the intricate biological diversity of MDD, treatment efficacy remains limited. Immune biomarkers have emerged as potential predictors of treatment response, underscoring the interaction between the immune system and the brain. This study investigated the relationship between cytokine levels and cortical thickness in patients with MDD, focusing on the corticolimbic circuit, to elucidate the influence of neuroinflammation on structural brain changes and contribute to a deeper understanding of the pathophysiology of MDD. MethodA total of 114 patients with MDD and 101 healthy controls (HC) matched for age, sex, and body mass index (BMI) were recruited. All participants were assessed for depression severity using the Hamilton Depression Rating Scale (HDRS), and 3.0 T T1 weighted brain MRI data were acquired. Additionally, cytokine levels were measured using a highly sensitive bead-based multiplex immunosorbent assay. ResultsPatients diagnosed with MDD exhibited notably elevated levels of interleukin-6 (p = 0.005) and interleukin-8 (p = 0.005), alongside significant cortical thinning in the left anterior cingulate gyrus and left superior frontal gyrus, with these findings maintaining significance even after applying Bonferroni correction. Furthermore, increased interleukin-6 and interleukin-8 levels in patients with MDD are associated with alterations in the left frontomarginal gyrus and right anterior cingulate cortex (ACC). ConclusionsThis suggests a potential influence of neuroinflammation on right ACC function in MDD patients, warranting longitudinal research to explore interleukin-6 and interleukin-8 mediated neurotoxicity in MDD vulnerability and brain morphology changes.

Mutual communication between radiosensitive and radioresistant esophageal cancer cells modulates their radiosensitivity

Radiotherapy is an important treatment modality for patients with esophageal cancer; however, the response to radiation varies among different tumor subpopulations due to tumor heterogeneity. Cancer cells that survive radiotherapy (i.e., radioresistant) may proliferate, ultimately resulting in cancer relapse. However, the interaction between radiosensitive and radioresistant cancer cells remains to be elucidated. In this study, we found that the mutual communication between radiosensitive and radioresistant esophageal cancer cells modulated their radiosensitivity. Radiosensitive cells secreted more exosomal let-7a and less interleukin-6 (IL-6) than radioresistant cells. Exosomal let-7a secreted by radiosensitive cells increased the radiosensitivity of radioresistant cells, whereas IL-6 secreted by radioresistant cells decreased the radiosensitivity of radiosensitive cells. Although the serum levels of let-7a and IL-6 before radiotherapy did not vary significantly between patients with radioresistant and radiosensitive diseases, radiotherapy induced a more pronounced decrease in serum let-7a levels and a greater increase in serum IL-6 levels in patients with radioresistant cancer compared to those with radiosensitive cancer. The percentage decrease in serum let-7a and the percentage increase in serum IL-6 levels at the early stage of radiotherapy were inversely associated with tumor regression after radiotherapy. Our findings suggest that early changes in serum let-7a and IL-6 levels may be used as a biomarker to predict the response to radiotherapy in patients with esophageal cancer and provide new insights into subsequent treatments.

Serum levels of Interleukin-6 in patients with Idiopathic Carpal Tunnel Syndrome: A case control study in Najaf Province

Background: Carpal Tunnel Syndrome (CTS) is a disease caused by a compression of the median nerve at the wrist within carpal canal that lead to multiple symptoms as paraesthesia, numbness and pain sensation in the median distribution fingers. If untreated, it leads to sensation loss, thenar muscle weakness and atrophy. It is most frequent peripheral neuropathy of upper limbs and is most predominant in female gender. The pathogenesis of CTS is yet unknown, and the majority of conditions are idiopathic. Interleukin 6 is a cytokine that has multiple functions including pro-inflammatory and anti-inflammatory or regenerative actions. The impact of serum inflammatory cytokines on incidence and severity of CTS is still unclear. Aim of the study: this study aims to correlate the clinical severity of CTS and the serum interleukin 6 concentrations. Patients and methods: This is a case control study which involved 140 participants who were categorized into 70 patients with CTS and 70 healthy persons according to clinical assessment and nerve conduction study results. After that, the participants were divided to normal, mild, moderate and severe groups according to Boston carpal tunnel questionnaire (BCTQ). Then, a blood sample was taken from each participant to assess serum interleukin 6 levels. A statistical analysis by SPSS was done for the collected data. Results: The study has shown that there was no significant correlation between serum interleukin 6 levels and the clinical severity score of CTS (P value &gt;0.05). Conclusion: It has been concluded that serum interleukin 6 levels did not have an impact on incidence and clinical severity of CTS and that its role in CTS is yet unclear.

Relationship between serum interleukin-6 levels and severity of coronary artery disease undergoing percutaneous coronary intervention

BackgroundCytokines play a potential role in atherosclerosis pathogenesis and progression. We investigated the association of interleukin-6 (IL-6) with the angiographic severity of coronary artery disease (CAD).MethodsThree hundred ten angiografically diagnosed CAD patients and 210 controls were enrolled in this study. CAD patients were stratified according to IL-6 cut-off value into high levels IL-6 group (≥ 9.5 pg/mL) and low levels IL-6 group (< 9.5 pg/mL). The severity of CAD was assessed according to Gensini score (GS), artery stenosis degree and the number of vessels involved. The mean age was 60.3 ± 11.0 years.ResultsThe level of IL-6 in patients was increased compared to controls and ranged from 1.5 to 3640.0 pg/mL. High levels of IL-6 were significantly associated with high levels of GS (> 40) but not with stenosis degree and vessel score. GS levels were significantly more elevated in patients with high levels of IL-6 group than in low IL6 levels patients (60.6 ± 39.5 vs 46.7 ± 37.2; p = 0.027). The analysis of the ROC curve performed in myocardial infarction patients showed that IL-6 (AUC: 0.941 (CI 95% 0.886, 0.997; p < 0.001) could be a powerful predictor marker in evaluating the infarct size after myocardial infarction when compared to myonecrosis biomarkers.ConclusionsIL-6 levels were associated with the severity of CAD assessed by the GS. Based on the highest levels of IL-6 measured in patients with STEMI, our study strongly suggests that IL-6 could be a powerful marker in evaluating the myocardial necrosis.Trial registrationClinicalTrials.gov Number: NCT03075566 (09/03/2017).

C‑reactive protein and related predictors in soft tissue sarcoma (Review).

C-reactive protein (CRP) is a useful predictor of poor survival in patients with several types of cancer because inflammation is strongly associated with cancer progression. The production of CRP in hepatocytes appears to be primarily induced at the transcriptional level following the elevation of circulating interleukin-6 (IL-6), which is produced by various cell types, including cancer cells and cancer-associated fibroblasts. Serum CRP levels are associated with serum IL-6 levels in patients with soft tissue sarcoma (STS). Additionally, patients with elevated CRP levels had worse oncological outcomes than those with normal CRP levels. It has been attempted to combine CRP levels with other inflammatory or immune markers, and the utility of this has been demonstrated. Therefore, a novel treatment strategy should be developed for patients with STS with elevated CRP levels. The present review aimed to clarify the role of CRP levels and related tools in predicting clinical outcomes in patients with STS.

Relationship between salivary levels of interleukin-8 and HbA1c in patients with type 2 diabetes.

Diabetes mellitus is a metabolic disease, which genetic and environmental factors play a role in its pathogenesis. Cytokines as important elements in the immune system have diverse expressions in different individuals and societies and are effective in the pathogenesis of diabetes. This study investigated the relationship between blood sugar control and salivary levels of interleukin-8 (IL-8) in patients with type 2 diabetes. This cross-sectional study was conducted on 73 subjects (35 diabetic and 38 healthy individuals). Unstimulated saliva samples were collected and the correlation between IL-8, as an inflammatory marker and HbA1c (Haemoglobin A1C) was studied. The levels of IL-8 and HbA1c were significantly higher in the patient group than control group (p < .001, p < .001, respectively). There was not any relationship between salivary IL-8 levels and glycemic control levels (p = .629). Also, there was no remarkable difference between men and women in terms of the levels of IL-8 and HbA1c saliva (p = .524, p = .998, respectively). Although the salivary IL-8 levels were higher in the diabetic patients, blood sugar control did not significantly affect cytokine concentrations. Increased salivary levels of IL-8 in patients with type 2 diabetes could be a basis for risk assessment, prevention and treatment of diabetes-related complications.

Evaluating the plasma interleukin-1 beta and interleukin-8 levels in patients with chronic obstructive pulmonary diseases following treatment with allogeneic mesenchymal stem cell derived from umbilical cord tissues and platelet rich plasma

Chronic obstructive pulmonary disease (COPD) is a common disease which negatively affects living quality and longevity of patients. Unfortunately, current COPD treatments are not radical. COPD is characterized by persistent neutrophil infiltrations mediated by inflammatory cytokines including interleukin (IL)-1β and IL-8 in the airway. Mesenchymal stem cells (MSCs) have been proven to suppress inflammation, modulate the immune system and can be regenerative. Allogeneic MSCs have been used to treat COPD patients across the world and produced positive clinical outcomes. In this study, we evaluated plasma IL-1β and IL-8 concentrations in 10 stage-D COPD patients before being transplanted with allogeneic MSCs derived from umbilical cord tissues (UC-MSCs) activated by platelet-rich plasma (PRP) and at 4 follow- ups (after 1, 3, 7, 12 months), as well as determined their associations with COPD clinical and sub-clinical parameters. Plasma IL-1β and IL-8 concentrations were measured using Multiplex Immunoassay. We found that plasma IL-8 levels were significantly reduced from 3.2 to 1.9 pg/ml after 12 months of treatment which is accompanied by the notable decrease in C-reactive protein (CRP). Exacerbation episodes were significantly decreased from 3 to 1. Plasma IL-1β levels were positively correlated with IL-8 levels and white blood cell (WBC) levels. Parallel measurements of plasma IL-1β and IL-8 may help assess the disease progression of COPD patients after the treatment with UC- MSCs and PRP. Blockage of IL-1β or IL-8 could be a valid strategy for the prevention and control of COPD.

Elevated interleukin-10 levels in patients with ocular toxoplasmosis.

In elderly patients, ocular toxoplasmosis is one of the most common etiologies of uveitis, which should be differentially diagnosed from ocular lymphoma, another common pathology of uveitis in older adults. The high level of interleukin (IL)-10 and an IL-10/IL-6 ratio higher than 1 (>1.0) are helpful parameters to diagnose ocular lymphoma. In this study, we used aqueous humor samples to detect 4 cases of ocular toxoplasmosis in patients with high levels of IL-10 and an IL-10/IL-6 ratio higher than 1. Our results show that ocular toxoplasmosis may be associated with increased cytokine levels in aqueous humor.

Sivelestat sodium for treatment of patients with COVID-19-associated acute respiratory distress syndrome in intensive care unit: a single-center retrospective cohort study

To investigate the effect of sivelestat sodium on survival, oxygenation index, and serum markers for infection in critically ill patients with COVID-19-associated acute respiratory distress syndrome (ARDS). This retrospectively study was performed among the critically ill patients with COVID-19-associated ARDS admitted in the intensive care unit (ICU) at Nanfang Hospital, Southern Medical University. We collected the clinical data of the patients on the first day of ICU admission and on the day of discharge and laboratory tests results of interleukin-6 (IL-6), C-reactive protein (CRP) and procalcitonin (PCT) and oxygenation index on days 1, 3 and 7 following ICU admission. Propensity-score matching was used to match the patients receiving sivelestat sodium to those without the treatment. Cox proportional hazards model and linear regression analysis were used to assess the association of sivelestat sodium treatment with in-hospital mortality and the length of hospital stay. A total of 199 patients with COVID-19-associated ARDS patients were included for data analysis. After propensity-score matching PSM, 35 patients receiving sivelestat sodium were matched to 70 patients without the treatment. Treatment with of sivelestat sodium was not associated with the reduction of in- hospital mortality (P=0.36), prolonged ICU stay (P=0.39), hospital stay (P=0.68) or improved oxygenation index (P>0.05) of the patients. No significant difference was found in serum CRP or PCT levels between the patients with and without sivelestat sodium treatment, but a significant reduction in IL-6 level was found in sivelestat sodium group (P=0.016). Sivelestat sodium treatment is not correlated with the reduction of mortality or length of hospital stay, but is associated with reduced serum IL-6 level in patients with COVID-19-associated ARDS.

High expression of IL6 and decrease in immune cells in COVID-19 patients combined with myocardial injury.

Myocardial injury, as a serious complication of coronavirus disease-2019 (COVID-19), increases the occurrence of adverse outcomes. Identification of key regulatory molecules of myocardial injury may help formulate corresponding treatment strategies and improve the prognosis of COVID-19 patients. Gene Set Enrichment Analysis (GSEA) was conducted to identify co-regulatory pathways. Differentially expressed genes (DEGs) in GSE150392 and GSE169241 were screened and an intersection analysis with key genes of the co-regulatory pathway was conducted. A protein-protein interaction (PPI) network was constructed to screen for key regulatory genes. Preliminarily screened genes were verified using other datasets to identify genes with consistent expression. Based on the hierarchical cluster, we divided the patients from GSE177477 into high- and low-risk groups and compared the proportion of immune cells. A total of 267 COVID-19 patients from the Zhejiang Provincial Hospital of Chinese Medicine from December 26, 2022, to January 11, 2023, were enrolled to verify the bioinformatics results. Univariate and multivariate analyses were performed to analyze the risk factors for myocardial injury. According to high-sensitivity troponin (hsTnI) levels, patients with COVID-19 were divided into high- and low-sensitivity groups, and interleukin 6 (IL6) expression and lymphocyte subsets were compared. Patients were also divided into high and low groups according to the IL6 expression, and hsTnI levels were compared. Interleukin signaling pathway and GPCR ligand binding were shown to be co-regulatory pathways in myocardial injury associated with COVID-19. According to the hierarchical cluster analysis of seven genes (IL6, NFKBIA, CSF1, CXCL1, IL1R1, SOCS3, and CASP1), patients with myocardial injury could be distinguished from those without myocardial injury. Age, IL6 levels, and hospital stay may be factors influencing myocardial injury caused by COVID-19. Compared with COVID-19 patients without myocardial injury, the levels of IL6 in patients with myocardial injury increased, while the number of CD4+ T cells, CD8+ T cells, B cells, and NK cells decreased (P<0.05). The hsTnI levels in COVID-19 patients with high IL6 levels were higher than those in patients with low IL6 (P<0.05). The COVID-19 patients with myocardial injury had elevated IL6 expression and decreased lymphocyte counts. IL6 may participate in myocardial injury through the interleukin signaling pathway.

Empagliflozin Reduces Interleukin-6 Levels in Patients with Heart Failure.

Background: The inhibition of sodium-glucose co-transporter 2 (SGLT-2) has been shown to be beneficial in the treatment of diabetic and non-diabetic patients with heart failure. The underlying mechanisms are incompletely understood. The present prospective study investigates for the first time the effect of empagliflozin on various soluble markers of inflammation in patients with reduced ejection fraction (HFrEF). Methods: We included 50 inpatients with HFrEF and diabetes mellitus type 2. A total of 25 patients received a therapy with the SGLT-2-inhibitor empagliflozin in addition to standard medication; the other 25 patients did not receive empagliflozin and were considered the control group. Quality of life, functional status and soluble immunological parameters in serum were assessed at baseline and after 3 months. Results: The baseline characteristics of both groups revealed no significant differences. Patients on empagliflozin demonstrated a significant improvement in the Minnesota living with heart failure questionnaire (baseline 44.2 ± 20.2 vs. 24 ± 17.7; p < 0.001), in distance in the 6-min walk test (baseline 343 ± 145 m vs. 450 ± 115 m; p < 0.001) and in soluble interleukin-6 level (baseline 21.7 ± 21.8 pg/mL vs. 13.7 ± 15.8 pg/mL; p = 0.008). There was no significant change of these or other parameters in the control group (p > 0.05 each). Conclusions: The empagliflozin-induced improvement of quality of life and functional capacity in patients with HFrEF and type 2 diabetes mellitus is accompanied by a substantial reduction of interleukin-6 levels. Thus, anti-inflammatory effects may contribute to the benefits of SGLT-2-inhibitors in heart failure.

A systematic review and meta-analysis of changes in interleukin-8 levels in malaria infection

The roles of interleukin-8 (IL-8) in malaria are inconsistent and unclear. This study synthesised evidence for differences in IL-8 levels in patients with malaria of various levels of severity. Relevant studies were searched in Scopus, MEDLINE, Embase, CENTRAL and PubMed from inception to 22 April 2022. Pooled mean differences (MDs) and 95% confidence intervals (CIs) were estimated using the random effects model. Of 1083 articles retrieved from the databases, 34 were included for syntheses. The meta-analysis revealed increased IL-8 levels in individuals with uncomplicated malaria compared with those without malaria (P = 0.04; MD, 25.57 pg/mL; 95% CI, 1.70 to 49.43 pg/mL; I2, 99.53, 4 studies; 400 uncomplicated malaria, 204 uninfected controls). The meta-analysis revealed comparable levels of IL-8 between the two groups (P = 0.10; MD, 74.46 pg/mL; 95% CI, −15.08 to 164.0 pg/mL; I2, 9.03; 4 studies; 133 severe malaria cases, 568 uncomplicated malaria cases). The study found evidence of increased IL-8 levels in individuals with malaria compared with those without malaria. However, no differences were found in IL-8 levels between patients with severe and non-severe malaria. Further research is needed to investigate the IL-8 cytokine levels in patients with malaria of different levels of severity.

Evaluation of serum adipocytokine and interleukin-18 levels in patients with epilepsy

Objective: Epilepsy is a neurological disease characterized by recurrent seizures. The underlying pathophysiological mechanisms in epilepsy are not fully known. Our aim is to investigate the relationship between serum adipocytokine and interleukin (IL)-18 levels in epilepsy patients receiving and not receiving antiepileptic therapy.&#x0D; &#x0D; Method: Our study was established as three groups. I: Epilepsy patients receiving antiepileptic therapy (n=30), II: Newly diagnosed epilepsy patients (n=30) and III: Control group (n=30). Serum adipocytokine and IL-18 levels were measured by enzyme-linked immunoassorbent assay method.&#x0D; &#x0D; Results: It was determined that serum adipocytokine and IL-18 levels were increased in epilepsy patients who received topiramate treatment and did not receive antiepileptic therapy compared to the control group. Serum glucose, total protein, cholesterol and albumin concentrations of patients who received antiepileptic treatment were decreased compared to the control group (p0.05). It was found that the body mass index (BMI) ratio of epilepsy patients who received antiepileptic treatment decreased and was significant compared to the control group and the group that did not receive treatment (p
