RÉSUMÉ

Background: A combination of genetic and environmental factors contribute to the highly common, complex, and varied endocrine condition known as polycystic ovary syndrome (PCOS) in women. PCOS primarily affects women between the ages of 15 and 35 who are in the early to late stages of pregnancy. Thus, this study aimed to evaluate the serum levels of irisin, subfatin, and adropin in PCOS with and without obesity compared to the control group. Methods: The present cross-sectional study was conducted in 2022 at Al-Nahrain University/Department of Chemistry (Baghdad, Iraq). The serum levels of irisin, subfatin, and adropin were measured with the enzyme-linked immunosorbent assay (ELISA) method. Body mass index, lipid profile, insulin, fasting glucose, follicle-stimulating hormone, and luteinizing hormone levels were also evaluated. The data were analyzed using one-way analysis of variance (ANOVA) by GraphPad Prism software version 8.0.2. A P<0.05 was considered statistically significant. Results: The study population comprised PCOS patients (n=90, divided into 45 obese and 45 normal weight) and healthy women (n=30). According to the results, the serum levels of irisin were significantly higher (P<0.001) in obese and normal-weight PCOS patients than controls. While adropin and subfatin were significantly lower in PCOS than controls (P<0.001). Moreover, there are higher levels of serum insulin, fasting glucose, and luteinizing hormone in PCOS women than in healthy women. Conclusion: According to the findings, PCOS patients had a higher level of irisin than the controls. In addition, decreased subfatin and adropin levels were observed in PCOS patients compared with healthy women. Further research is required to confirm these results in the future.

RÉSUMÉ

Insofar as they play an important role in the pathogenesis of colorectal cancer (CRC), this study analyzes the serum profile of cytokines, chemokines, growth factors, and soluble receptors in patients with CRC and cancer-free controls as possible CRC signatures. Serum levels of 65 analytes were measured in patients with CRC and age- and sex-matched cancer-free controls using the ProcartaPlex Human Immune Monitoring 65-Plex Panel. Of the 65 tested analytes, 8 cytokines (CSF-3, IFN-γ, IL-12p70, IL-18, IL-20, MIF, TNF-α and TSLP), 8 chemokines (fractalkine, MIP-1ß, BLC, Eotaxin-1, Eotaxin-2, IP-10, MIP-1a, MIP-3a), 2 growth factors (FGF-2, MMP-1), and 4 soluble receptors (APRIL, CD30, TNFRII, and TWEAK), were differentially expressed in CRC. ROC analysis confirmed the high association of TNF-α, BLC, Eotaxin-1, APRIL, and Tweak with AUC > 0.70, suggesting theranostic application. The expression of IFN-γ, IL-18, MIF, BLC, Eotaxin-1, Eotaxin-2, IP-10, and MMP1 was lower in metastatic compared to non-metastatic CRC; only AUC of MIF and MIP-1ß were > 0.7. Moreover, MDC, IL-7, MIF, IL-21, and TNF-α are positively associated with tolerance to CRC chemotherapy (CT) (AUC > 0.7), whereas IL-31, Fractalkine, Eotaxin-1, and Eotaxin-2 were positively associated with resistance to CT. TNF-α, BLC, Eotaxin-1, APRIL, and Tweak may be used as first-line early detection of CRC. The variable levels of MIF and MIP-1ß between metastatic and non-metastatic cases assign prognostic nature to these factors in CRC progression. Regarding tolerance to CT, MDC, IL-7, MIF, IL-21, and TNF-α are key when down-regulated or resistant to treatment is observed.

RÉSUMÉ

BACKGROUND: Traumatic liver injury is an acute event that triggers liver repair. The augmenter of liver regeneration (ALR) has been identified as a growth factor involved in this process. This study evaluates the impact of ALR on isolated liver blunt trauma and examines its relationship with various time intervals. METHODS: Forty healthy female Wistar albino rats were divided into five groups (n=8 each). Isolated blunt liver trauma was induced using a custom-designed trauma platform in all groups except for Group 1. The groups were categorized by the timing of euthanasia post-trauma: 2nd (15 minutes), 3rd (30 minutes), 4th (45 minutes), and 5th (60 minutes). Assessments included plasma ALR levels, liver tissue ALR levels (both intact and lacerated), biochemical indices, and liver histological analysis. RESULTS: Plasma ALR levels in Group 4 were higher than in Groups 1 and 2 (p<0.01). Intact liver ALR levels in Groups 3 and 4 exceeded those in Group 1 (p<0.05, p<0.01, respectively). Intact liver tissue ALR levels in Group 5 were lower than in Groups 3 and 4 (p<0.05, p<0.01, respectively). Lacerated liver tissue ALR levels in Group 5 were higher than those in Groups 2 and 3. In Group 1, the plasma ALR level was higher than the intact liver tissue ALR level (p<0.05). In Group 2, plasma ALR levels exceeded those in intact liver tissue ALR levels (p<0.01). In Group 3, plasma ALR levels surpassed both lacerated and intact liver tissue ALR levels (p<0.05, p<0.001, respectively). In Group 4, the plasma ALR level was higher than the intact liver tissue ALR level (p<0.01), and the lacerated liver tissue level was higher than the intact liver ALR level (p<0.001). Additionally, inflammation scores were higher in Groups 3, 4, and 5 compared to Group 2 (p<0.05, p<0.01, p<0.01, respectively). CONCLUSION: This study is the first to explore the role of ALR in isolated blunt liver trauma. Following blunt liver trauma, both plasma and liver tissue ALR levels change within minutes.

RÉSUMÉ

OBJECTIVE: Studies have shown that members of the salusin family regulate the migration and proliferation of arterial smooth muscle cells and increase the tendency to atherosclerosis through fibrosis and calcification in the vascular wall. However, the effect of salusins on the uterine artery has not yet been investigated. This study was conducted to investigate whether serum salusin alpha and beta concentrations in the first trimester are associated with diastolic notching in uterine artery Doppler. METHODS: This non-interventional cohort study was conducted on 88 pregnant women, 44 of whom had diastolic notching on unilateral or bilateral uterine artery Doppler, and 44 of whom did not have diastolic notching on uterine artery Doppler. The uterine artery notch positive and negative groups were compared in terms of serum salusin alpha and beta concentrations. RESULTS: The two groups were similar in terms of demographic characteristics (p < 0.05). The median salusin alpha concentration was found to be 689.4 pg/ml in the uterine artery notch positive group, while it was 734.6 pg/ml in the uterine artery notch negative group (p = 0.608). The median salusin beta concentration was found to be 674.5 pg/ml in the uterine artery notch positive group, while it was 693.8 pg/ml in the uterine artery notch negative group (p = 0.453).Participants were regrouped into normal and high uterine artery resistance and compared in terms of serum salusin alpha and beta concentrations. The median salusin alpha concentration was found to be 994.5 pg/ml in the high uterine artery PI group, while it was 685.2 pg/ml in the normal uterine artery PI group (p = 0.698). The median salusin beta concentration was found to be 1,100.8 pg/ml in the high uterine artery PI group, while it was 669.1 pg/ml in the normal uterine artery PI group (p = 0.584). CONCLUSION: Although the sample size was too small to draw a definitive conclusion, our results indicate that uterine artery diastolic notching or increased resistance in the uterine artery does not appear to be associated with serum salusin alpha or beta concentrations.

RÉSUMÉ

BACKGROUND: This study aimed to evaluate the significance of serum salusin beta (SAL-ß) levels in predicting the severity of acute pancreatitis (AP) in patients diagnosed with this condition and to assess its relationship with disease and prognosis. METHODS: Sixty-four patients between 18 and 100 years of age diagnosed with AP, were included in the study. Patients were categorized into 3 groups based on the Revised Atlanta Classification: mild, moderate, and severe AP. Eighteen healthy adults were included as the control group. Sex, age, height, weight, presence of additional diseases, laboratory results, imaging findings, levels of white blood cells, neutrophil-lymphocyte ratio, mean platelet volume, amylase, lipase, sensitive C-reactive protein, sedimentation, and serum SAL-ß were measured and recorded. SAL-ß levels were reevaluated on the third day of hospitalization. RESULTS: The average age of the patients included in the study was 62.66 ±â€…17.67. Gallstones were present in 64.1% of the patients. The difference in the SAL-ß averages on the 1st and 3rd days was statistically significant (P < .05). On the first day, the SAL-ß averages of those with severe Atlanta scores were higher than those with mild and moderate Atlanta severity. Similarly, on the third day, the SAL-ß averages of those with severe Atlanta scores were higher than those with mild and moderate Atlanta severity. According to receiver operating characteristic analysis using the Youden index, the cutoff value for SAL-ß for severe pancreatitis was 178.8 pg/mL on the 1st day and 207.5 pg/mL on the 3rd day. CONCLUSION: SAL-ß can be used to detect and monitor severe pancreatitis. Further extensive clinical studies with larger case series are needed.

RÉSUMÉ

BACKGROUND Preliminary data suggest an adipogenic role for growth arrest-specific 6 (Gas6), a pleiotropic molecule involved in inflammation, proliferation, and hemostasis through its Tyro3, Axl, and MerTK (TAM) receptors. This study compares Gas6 expression in plasma and visceral and subcutaneous adipose tissue in 42 adults with obesity (body mass index ≥40 kg/m²) and 32 normal-weight controls to elucidate its role in obesity and related metabolic alterations. MATERIAL AND METHODS Using a case-control design, we measured Gas6 levels in plasma via a validated sandwich enzyme-linked immunosorbent assay and in adipose tissues through quantitative polymerase chain reactio with specific probes. Medians and correlations were analyzed using Mann-Whitney and Spearman tests. A general linear model assessed the impact of covariates on the Gas6-anthropometric relationship, with statistical significance determined by P values. RESULTS Plasma Gas6 levels were significantly higher in the obese group than in controls (P=0.0006). While Gas6 mRNA expression did not significantly differ in subcutaneous adipose tissue between groups, it was notably higher in visceral than subcutaneous adipose tissue in controls (P<0.05). A significant correlation was found between plasma Gas6 levels and body mass index (P=0.001). CONCLUSIONS Gas6 plasma levels are elevated in morbid obesity, particularly in visceral adipose tissue, and are linked to altered glucose tolerance in female patients. These findings highlight the role of Gas6 in obesity-related metabolic complications and suggest avenues for further research and potential therapies.

RÉSUMÉ

BACKGROUND: Standard tools are not sensitive enough for hepatocellular carcinoma (HCC) early detection. This study aimed to evaluate the accuracy of dickkopf-1 (DKK1) and soluble Axl (sAxl) and their combined for early differentiating of HCC from premalignant benign liver diseases. METHODS: A total of 210 chronic hepatitis C (CHC) patients (55 fibrotic, 45 cirrhotic and 110 HCC) were enrolled. Both DKK1 and sAxl were tested using ELISA for all participants. RESULTS: HCC patients were accompanied by a significant increase (P<0.05) in DKK1 (5.38±2.05 ng/mL) and sAxl (178.02±49.39 ng/mL) compared to patients with fibrosis (2.16±0.6, 97.63±19.71 ng/mL, respectively) and cirrhosis (2.62±0.8, 121.84±34.66 ng/mL, respectively). Both DKK1 (AUC=0.852) and sAxl (AUC=0.882) had a good diagnostic accuracy in separating HCC from all non-HCC patients. Multiplying DKK1 with sAXL yielded values that significantly (P=0.0001) increased in patients who developed HCC (674.3 (434.2-1413.9)) versus fibrotic (204.9 (161.7-262)) and cirrhotic (254.4 (205.4-343.7)) patients. This model improves HCC diagnostic performances [AUC=0.921; sensitivity 90.9%, specificity 87%, PPV 88.5%, NPV 89.7% and efficiency 89.1%]. Elevated DKK1×sAxl values were associated with aggressive tumor features including multiple nodules, large size, Child-Pugh and BCLC late stages. CONCLUSIONS: combined use of DKK1×sAxl is simple and feasible HCC diagnostic model that could enhance HCC diagnostic accuracy and could replace AFP in follow up of patients with premalignant diseases.

RÉSUMÉ

Background and Objective: Colorectal cancer (CRC) is among the most common types of cancer. Although the disease is treatable in its early stages, five-year survival falls below 20% in the later stages. CEA and CA19-9 are tumor markers used in the diagnosis and follow-up of the disease in clinical practice; however, their diagnostic effectiveness is insufficient. Therefore, the identification of biomarkers that can be easily studied from serum and can diagnose CRC and determine its severity is highly important. In this context, dickkopf1 (DKK1) and cytoskeleton-associated protein 4 (CKAP4) are both promising biomarkers. Materials and Methods: Serum DKK1 and CKAP4 levels were measured in 55 patients with CRC and 40 healthy controls. The patients with CRC were divided into groups based on pathological stages and histological differentiation. The serum levels of both proteins in patients with CRC were measured preoperatively and 10 and 30 days postoperatively. Results: Serum DKK1 and CKAP4 were significantly higher in the CRC group than in the healthy controls (p < 0.05). Serum levels of both proteins rose in line with the disease stage and grade but decreased following surgical resection. A positive correlation was observed between tumor diameter and protein blood levels. The diagnostic efficacy of DKK1 and CKAP4 in CRC (approximately 95%) was higher than that of markers such as CEA and CA19-9. Conclusions: The DKK1 and CKAP4 serum values of patients with CRC are promising biomarkers. They can potentially be used in CRC management, namely, in the diagnosis and treatment of tumor response access and in tumor aggressiveness prediction.

RÉSUMÉ

INTRODUCTION: Dual diagnosis in individuals with cocaine use disorders (CUDs) presents a mental health challenge marked by an increased susceptibility to disabling morbidities and premature mortality. Despite extensive research on depression and anxiety, other prevalent comorbidities, such as psychotic and personality disorders, have received less attention. This study explores inflammation-related mediators as potential biomarkers for CUD and dual diagnosis with schizophrenia (SCZ) or antisocial personality disorder (APD). METHODS: This exploratory study included 95 participants, comprising 40 healthy subjects and 55 abstinent patients with CUD. Lifetime CUD was diagnosed either as single diagnosis (CUD group, N = 25) or as a dual diagnosis (DD group. N = 30) with SCZ (CUD+SCZ subgroup) or APD (CUD+APD subgroup). Participants were clinically assessed, and the plasma concentrations of growth factors (i.e., G-CSF, BDNF, and VEGF-A) and chemokines (i.e., CCL11/eotaxin-1, CCL2/MCP-1, and CXCL12/SDF-1) were determined and log(10)-transformed for analysis. RESULTS: Growth factors and chemokines were dysregulated by CUD and psychiatric diagnoses. Specifically, patients in the CUD group exhibited significantly lower concentrations of G-CSF and CCL11/eotaxin-1 than the control group. In contrast, the DD group showed significantly higher concentrations of all analytes than both the CUD and control groups. Additionally, no differences in these analytes were observed between the CUD+SCZ and CUD+APD subgroups within the DD group. Regarding cocaine-related variables, significant associations were identified in the CUD group: an inverse correlation between the age at first cocaine use and the concentrations of BDNF and CCL2/MCP-1; and a positive correlation between the duration of the cocaine abstinence and the concentrations of BDNF and CCL11/eotaxin-1. Lastly, a logistic regression model incorporating all these analytes demonstrated high discriminatory power in distinguishing patients with CUD alone from those with dual diagnosis. CONCLUSIONS: Individuals with dual diagnosis of CUD exhibit elevated concentrations of growth factors and chemokines, distinguishing them from those with CUD alone. It is unclear whether the differences in these inflammatory mediators are specific to the presence of SCZ and APD. The study highlights potential biomarkers and associations, providing valuable insights into the intricate interplay of CUD and psychiatric disorders to enhance clinical diagnosis and therapeutics.

RÉSUMÉ

Introduction: The protein growth arrest-specific 6 (Gas6) and its tyrosine kinase receptors Tyro-3, Axl, and Mer (TAM) are ubiquitous proteins involved in regulating inflammation and apoptotic body clearance. Multiple sclerosis (MS) is the most common inflammatory demyelinating disease of the central nervous system leading to progressive and irreversible disability if not diagnosed and treated promptly. Gas6 and TAM receptors have been associated with neuronal remyelination and stimulation of oligodendrocyte survival. However, few data are available regarding clinical correlation in MS patients. We aimed to evaluate soluble levels of these molecules in the cerebrospinal fluid (CSF) and serum at MS diagnosis and correlate them with short-term disease severity. Methods: In a prospective cohort study, we enrolled 64 patients with a diagnosis of clinical isolated syndrome (CIS), radiological isolated syndrome (RIS) and relapsing-remitting (RR) MS according to the McDonald 2017 Criteria. Before any treatment initiation, we sampled the serum and CSF, and collected clinical data: disease course, presence of gadolinium-enhancing lesions, and expanded disability status score (EDSS). At the last clinical follow-up, we assessed EDSS and calculated MS severity score (MSSS) and age-related MS severity (ARMSS). Gas6 and TAM receptors were determined using an ELISA kit (R&D Systems) and compared to neurofilament (NFLs) levels evaluated with SimplePlex™ fluorescence-based immunoassay. Results: At diagnosis, serum sAxl was higher in patients receiving none or low-efficacy disease-modifying treatments (DMTs) versus patients with high-efficacy DMTs (p = 0.04). Higher CSF Gas6 and serum sAXL were associated with an EDSS <3 at diagnosis (p = 0.04; p = 0.037). Serum Gas6 correlates to a lower MSSS (r2 = -0.32, p = 0.01). Serum and CSF NFLs were confirmed as disability biomarkers in our cohort according to EDSS (p = 0.005; p = 0.002) and MSSS (r2 = 0.27, p = 0.03; r2 = 0.39, p = 0.001). Results were corroborated using multivariate analysis. Conclusions: Our data suggest a protective role of Gas6 and its receptors in patients with MS and suitable severity disease biomarkers.

RÉSUMÉ

Proinflammatory cytokines and their inhibitors are involved in the regulation of multiple immune reactions including response to transplanted organs. In this prospective study, we evaluated changes in serum concentrations of six IL-1 family cytokines (IL-1 alpha, IL-1 beta, IL-1RA, IL-18, IL-18BP, and IL-36 beta) in 138 kidney allograft recipients and 48 healthy donors. Samples were collected before transplantation and then after one week, three months and one year, additional sera were obtained at the day of biopsy positive for acute rejection. We have shown, that concentrations of proinflammatory members of the IL-1 family (IL-1ß, IL-18, IL-36 ß) and anti-inflammatory IL-18BP decreased immediately after the transplantation. The decline of serum IL-1RA and IL-1α was not observed in subjects with acute rejection. IL-18, including specifically its free form, is the only cytokine which increase serum concentrations in the period between one week and three months in both groups of patients without upregulation of its inhibitor, IL-18BP. Serum concentrations of calculated free IL-18 were upregulated in the acute rejection group at the time of acute rejection. We conclude that IL-1 family cytokines are involved mainly in early phases of the response to kidney allograft. Serum concentrations of free IL-18 and IL-18BP represent possible biomarkers of acute rejection, and targeting IL-18 might be of therapeutic value.

RÉSUMÉ

BACKGROUND: This study aimed to assess and compare the concentrations of growth factors, white blood cells (WBCs), and platelets in injectable platelet-rich fibrin (i-PRF) derived from people with healthy periodontal conditions and those with chronic periodontitis. METHODS: Venous blood samples were obtained from 30 patients diagnosed with chronic periodontitis (test group) and 30 participants with healthy periodontal conditions (control group). The i-PRF was then acquired from centrifuged blood. The growth factors (VEGF, IGF-1, TGF-ß1, PDGF-BB and EGF) released from the i-PRF samples were compared between groups with ELISA testing. The amounts of WBCs and platelets were also compared. RESULTS: No significant differences in the concentrations of growth factors were found between the groups (the mean values for the control and test groups were, respectively: IGF: 38.82, 42.46; PDGF: 414.25, 466.28; VEGF: 375.69, 412.18; TGF-ß1: 21.50, 26.21; EGF: 138.62, 154.82). The test group exhibited a significantly higher WBC count than the control group (8.80 vs. 6.60, respectively). However, the platelet count did not show a statistically significant difference between the groups (control group 242.0 vs. test group 262.50). No significant correlation was observed between WBC count and growth factor level in either group. CONCLUSIONS: The growth factor levels in i-PRFs did not exhibit significant difference between the two groups. This suggests that the levels of these growth factors may be unaffected by the periodontal disease.

RÉSUMÉ

BACKGROUND AND AIMS: There is a lack of evidence on dietary intake of methyl donor nutrients with metabolic health status and related biomarkers. Thus, this study aimed to assess the relation between methyl donor nutrients intake and metabolic health status with regarding the interactive roles of brain-derived neurotrophic factor (BDNF) and adropin in Iranian adults. METHODS: This cross-sectional survey was conducted among 527 Iranian adults (45.7% female) selected by multistage cluster random-sampling method. A validated food frequency questionnaire was used to evaluate participants' dietary intake. Metabolic unhealthy status was defined by Wildman criteria as having ≥ 2 of hyperglycemia, hypertriglyceridemia, hypo-HDL-cholesterolemia, hypertension, chronic inflammation, and insulin resistance. Concentrations of metabolic parameters, BDNF and adropin were determined using fasting blood samples. RESULTS: An inverse association was found between methyl donor nutrients intake and metabolically unhealthy status in multivariable-adjusted model (ORT3 vs. T1 = 0.30; 95%CI: 0.12-0.75). This association was especially significant among overweight/obese adults and was stronger in women. Additionally, consumption of vitamin B6 and choline was separately related to reduced odds of metabolically unhealthy status. Methyl donor intake was not significantly related to low BDNF (ORT3 vs. T1 = 0.93; 95%CI: 0.60-1.44) and adropin (ORT3 vs. T1 = 0.71; 95%CI: 0.44-1.15). However, the interaction between high methyl donor nutrients intake and high BDNF was related to lower odds of metabolically unhealthy status in multivariable-adjusted model (ORMDNS∗BDNF = 0.27; 95%CI: 0.11-0.67). CONCLUSION: Higher intake of methyl donor nutrients, alone and in interaction with BDNF levels, was associated with decreased odds of metabolically unhealthy status in Iranian adults.

RÉSUMÉ

BACKGROUND/AIM: The acute phase immune response (APR) in midline laparotomy (MLa) patients following surgery has been rarely studied, with no studies assessing the association of blood IL-18 (interleukin-18) and IL-18BP (IL-18 binding protein) values with the numeric rating scale (NRS) pain score following MLa. PATIENTS AND METHODS: Blood levels of seven cytokines (CYT) (IL-18, IL-18BP, IL-1ra, IL-6, IL-8, IL-10, IL-1ß) and high-sensitivity C-reactive protein (hs-CRP) were measured at three time points; before operation (PRE), immediately after operation (POP1), and 24 h after operation (POP2) in 56 patients with MLa. The satisfaction of the patients at 24 h following MLa (SFS24; 0=fully unsatisfied; 10=fully satisfied) was recorded on a 11-point numeric rating scale. RESULTS: In all patients, the IL-18 and IL-18BP blood levels decreased at POP1 and the drop between the preoperative and POP1 levels in the IL-18 and IL-18BP was highly significant (p<0.001). However, the median IL-18 and IL-18BP blood levels increased significantly at POP2 (p<0.001) with the linear mixed-effect model (LME) showing a statistically significant time effect (p<0.001). The hs-CRP blood levels increased significantly at POP2 with the LME model showing a statistically significant time effect. The preoperative and POP2 IL-18 values were clearly higher in patients with cancer versus benign disease (177/182 vs. 135/126, p=0.039/p=0.013, respectively). Interestingly, in all patients of the study, the median IL-18 versus IL-18BP blood levels correlated at POP1 (r=0.315, p=0.036). CONCLUSION: A noteworthy discovery of this study is the correlation of IL-18BP with SFS24 (r=0.361, p=0.05), proposing that APR and quality of life are associated in MLa patients.

RÉSUMÉ

BACKGROUND: Secreted glycoproteins of the Dickkopf (DKK) family modify Wnt signaling and may influence plaque destabilization but their modulation by statins in MI patients is not known. METHODS: We measured plasma DKK-1 and DKK-3 in patients with acute ST-segment elevation MI (STEMI) before percutaneous coronary intervention (PCI) and after 2 and 7 days and 2 months in patients receiving short-term high-dose (40 mg rosuvastatin, given before PCI; n = 25) and moderate dose (20 mg simvastatin, given the day after PCI; n = 34). In vitro modulation of DKK-1 in human umbilical vein endothelial cells (HUVECs) by statins were assessed. RESULTS: (i) Patients receiving high dose rosuvastatin had a marked decline in DKK-1 at day 2 which was maintained throughout the study period. However, a more prevalent use of ß-blockers in the simvastatin group, that could have contributed to higher DKK-1 levels in these patients. (ii) There was a strong correlation between baseline DKK-1 levels and change in DKK-1 from baseline to day 2 in patients receiving high dose rosuvastatin treatment. (iii) DKK-3 increased at day 2 but returned to baseline levels at 2 months in both treatment groups. (iv) Statin treatment dose-dependently decreased DKK-1 mRNA and protein levels in HUVEC. CONCLUSIONS: Our findings suggest that high dose statin treatment with 40 mg rosuvastatin could persistently down-regulate DKK-1 levels, even at 2 months after the initial event in STEMI patients.

RÉSUMÉ

BACKGROUND: Gestational diabetes mellitus (GDM) is the most common metabolic complication, which leads to short and long-term consequences in both mother and fetus exposed to hyperglycemia. The aetiology of this condition is proposed to be based on the dysfunction of the adipose tissue, which is characterised by the aberrant generation of adipokines. One of them is preadipocyte factor-1 (Pref-1), which could mediate controlling the adaptation of the maternal metabolism to pregnancy. AIMS: The study aims to examine the level of Pref-1 in the cord blood of healthy pregnant women's neonates and fetuses born to mothers with GDM. MATERIALS AND METHODS: Cord blood samples were collected from 30 newborns of mothers with GDM and 40 newborns of healthy pregnant women. Pref-1 concentrations were measured with an ELISA kit. RESULTS: Fetal Pref-1 concentrations were significantly lower in newborns of mothers with GDM compared to the normal pregnancy group children (5.32 ± 0.29 vs. 7.38 ± 0.53; p < 0.001). Mothers with GDM had a significantly higher index of BMI before pregnancy, maternal gestational weight gain, and maternal fasting glucose. In-depth analysis through multiple variant linear regression revealed a significant association between fetal serum Pref-1 levels, exposure to GDM, and gestational age. CONCLUSION: These findings contribute valuable insights into maternal-fetal health and pave the way for more targeted and effective clinical interventions.

RÉSUMÉ

PURPOSE: Behçet's disease (BD) is an autoimmune chronic systemic inflammatory disease characterized by a versatile clinical spectrum. Growth arrest specific protein 6 (GAS6)/soluble AXL (sAXL) signaling pathway draws attention in the resolution of inflammation, and its deficiency is associated with chronic inflammatory, autoimmune diseases, as well as clearance of apoptotic cells by phagocytes - efferocytosis. In this study, it was aimed to investigate whether GAS6/sAXL, interleukin (IL)-10, nitric oxide (NO), and BCL-2 levels were associated with inflammation and efferocytosis contributes to the pathogenesis of BD. METHODS: A total of 37 Behçet patients with ocular involvement and 30 healthy control subjects were included in this study. GAS6, sAXL, IL-10, NO, and BCL-2 levels were quantified using enzyme-linked immunosorbent assay (ELISA) method. RESULTS: Serum GAS6, sAXL, IL-10, NO, and BCL-2 levels were significantly lower in patients with BD compared to the controls (P < 0.005, P < 0.001, P < 0.001, P < 0.001, and P < 0.001, respectively). In correlation analysis, research parameters decreased in patients with BD was significantly correlated with each other: GAS6-IL-10 (r = 0.585, P < 0.001), GAS6-BCL-2 (r = 0.541, P < 0.001), sAXL-BCL-2 (r = 0.696, P < 0.001), IL-10-NO (r = 0.717, P < 0.001), IL-10-BCL-2 (r = 0.759, P < 0.001), and NO-BCL-2 (r = 0.541, P < 0.001). CONCLUSION: In conclusion, decreased serum BCL-2 level may be an indicator of increased apoptosis in these patients and decreased levels of GAS6/sAXL, IL-10, and NO may indicate insufficient clearance of apoptotic bodies released as a result of increased apoptosis in BD patients.

RÉSUMÉ

OBJECTIVE: To explore the value of serum Dickkopf-3 (sDKK3) in predicting Early Neurological Deterioration (END) and in-hospital adverse outcomes in acute ischemic stroke (AIS) patients. METHODS: AIS patients (n = 200) were included and assessed by the National Institutes of Health Stroke Rating Scale. Serum Dkk3 levels were assessed by ELISA. END was defined as an increase of ≥ 4 points in NIHSS score within 72h. The biological threshold of sDKK3 level and END occurrence were predicted based on X-tile software. Primary outcomes were END and all-cause death, and the secondary outcome was ICU admission during hospitalization. The logistic regression model and Cox risk regression model were applied to evaluate the relationship between DKK3 level and END incidence, all-cause in-hospital mortality, and in-hospital adverse outcomes (ICU admission). RESULTS: During hospitalization, the incidence of END in patients with AIS was 13.0 %, and the mortality rate within 7 days after END was 11.54 % (3/26). In patients below the serum DKK3 cutoff (93.0 pg/mL), the incidence of END was 43.5 % (20/48). Patients with lower sDKK3 levels were associated with a 1.188-fold increased risk of developing END (OR = 1.188, 95 % CI 1.055‒1.369, p < 0.0001). However, there was no significant association with admission to the ICU. sDKK3 below the threshold (93.0 pg/mL) was a risk factor for death. CONCLUSION: Predictive threshold levels of serum DKK3 based on X-tile software may be a potential predictive biomarker of in-hospital END in patients with AIS, and low levels of DKK3 are independently associated with increased in-hospital mortality.

RÉSUMÉ

PURPOSE: Patients receiving long-term glucocorticoid (GC) treatment are at risk of osteoporosis, while bone effects of substitution doses in Addison's disease (AD) remain equivocal. The project was aimed to evaluate serum bone turnover markers (BTMs): osteocalcin, type I procollagen N-terminal propeptide (PINP), collagen C-terminal telopeptide (CTX), sclerostin, DKK-1 protein, and alkaline phosphatase (ALP) in relation to bone mineral density (BMD) during GC replacement. METHODS: Serum BTMs and hormones were assessed in 80 patients with AD (22 males, 25 pre- and 33 postmenopausal females) on hydrocortisone (HC) substitution for ≥3 years. Densitometry with dual-energy X-ray absorptiometry covered the lumbar spine (LS) and femoral neck (FN). RESULTS: Among BTMs, only PINP levels were altered in AD. BMD Z-scores remained negative except for FN in males. Considering T-scores, osteopenia was found in LS in 45.5% males, 24% young and 42.4% postmenopausal females, while osteoporosis in 9.0%, 4.0% and 21.1%, respectively. Lumbar BMD correlated positively with body mass (p = 0.0001) and serum DHEA-S (p = 9.899 × 10-6). Negative correlation was detected with HC dose/day/kg (p = 0.0320), cumulative HC dose (p = 0.0030), patient's age (p = 1.038 × 10-5), disease duration (p = 0.0004), ALP activity (p = 0.0041) and CTX level (p = 0.0105). However, only age, body mass, ALP, serum CTX, and sclerostin remained independent predictors of LS BMD. CONCLUSION: Standard HC substitution does not considerably accelerate BMD loss in AD patients and their serum BTMs: CTX, osteocalcin, sclerostin, DKK-1, and ALP activity remain within the reference ranges. Independent predictors of low lumbar spine BMD, especially ALP activity, serum CTX and sclerostin, might be monitored during GC substitution.
