Association of interleukin-18 gene polymorphism and its protein expression with the lower extremity deep venous thrombosis in the chinese han population: A case-control study.

ABSTRACT: OBJECTIVE:We aim to explain the correlation among IL-18 gene polymorphism, its protein expression and LEDVT in the Chinese Han population. METHODS:A total of 138 LEDVT patients and 150 healthy people volunteered as LEDVT and control groups. All the data, including the gender, age, BMI, levels of TG, LDL/HDL, TC, GLU, APTT, BUN, Cr, ALT, AST, ApoA1, ApoB, and Fg was detected. IL-18 level, IL-18 -137G/C and -607C/A polymorphism, and risk factors of LEDVT were detected using ELISA, PCR-RFLP and multivariate logistic regression analysis, respectively. RESULTS:Increased BMI, GLU, Fg, BUN, ApoB and IL-18 and decreased APTT were found in the LEDVT group. The GC + CC genotype and C allele in -137G/C polymorphism was elevated in the control group when compared to that in the LEDVT group. The IL-18 level was elevated in the case group when compared to the control group with respect to the same genotype in -607C/A and -137G/C polymorphisms, and in the LEDVT group, IL-18 level was higher in the GG genotype than that in the GC + CC genotype of -137G/C polymorphism. BUN, GG genotype and IL-18 level were independent risk factors, but APTT was a protective factor of LEDVT. CONCLUSION:On the basis of our results, we concluded that the GG genotype of -137G/C polymorphism and IL-18 level are independent risk factors of LEDVT, and IL-18 gene polymorphism affects the level of IL-18 in LEDVT patients.

Project description:BackgroundThe systemic immune-inflammation index (SII), as a novel inflammatory biomarker, has recently attracted attention in cardiovascular disease research. However, the relationship between SII and risk of lower extremity deep venous thrombosis (LEDVT) remains unclear to date. Thus, this study aimed to explore the association in a large sample over a 10-year period (2012-2022).MethodsAll hospitalized patients undergoing lower extremity compression ultrasonography (CUS) examination were consecutively screened by searching our hospital information system database. The receiver operating characteristic (ROC) curve analysis was used to identify the optimal cut-off value for high and low SII group. Multivariate logistic regression analyses were performed to investigate the relationship between SII and LEDVT risk. Propensity score matching (PSM), subgroup and sensitivity analyses were also conducted. Moreover, restricted cubic spline (RCS) regression and two-piecewise linear regression models were used to assess the dose-response relationship between natural log transformed SII [ln(SII)] and risk of LEDVT.ResultsA total of 16,725 consecutive hospitalized patients were included, and 1,962 LEDVT events occurred. After adjusting for confounding factors, patients in the high SII group (≥ 574.2 × 109/L) showed a 1.740-fold risk of LEDVT (95% CI: 1.546-1.959, P < 0.001), and elevated ln(SII) was associated with a 36.1% increased risk of LEDVT (95% CI: 1.278-1.449, P < 0.001). PSM, subgroup and sensitivity analyses confirmed the robustness of the association. A non-linear relationship was observed (P non-linear < 0.001), with a threshold value of 5.6 × 109/L for all LEDVT events. Above the threshold, each unit increase in ln(SII) had a 1.369-fold higher risk of LEDVT (95% CI: 1.271-1.475, P < 0.001). The association also existed in both distal and proximal LEDVT.ConclusionElevated SII is significantly associated with an increased risk of LEDVT in hospitalized patients. Additionally, the association is non-linear and exhibit a threshold effect.

Project description:ImportanceVenous thromboembolism is the second overall leading cause of death for patients with cancer, and there is an approximately 2-fold increase in fatal pulmonary embolism (PE) in patients with cancer. Inferior vena cava (IVC) filters are designed to prevent PE, but defining the appropriate use of IVC filters in patients with cancer remains a substantial unmet clinical need.ObjectiveTo evaluate the association of IVC filters with the development of PE in patients with cancer and deep venous thrombosis (DVT).Design, setting, and participantsA population-based cohort study was conducted using administrative data on 88 585 patients from the state inpatient databases for California (2005-2011) and Florida (2005-2014). Based on diagnostic and procedure codes, patients with cancer and acute lower extremity DVT were identified. All subsequent hospital visits for these patients were evaluated for the placement of an IVC filter, the development of new PE, the development of new DVT, and in-hospital mortality. Data analysis was performed from September 1 to December 1, 2019.ExposuresPlacement of an IVC filter.Main outcomes and measuresThe association of IVC filter placement with rates of new PE and DVT was estimated using a propensity score matching algorithm and competing risk analysis.ResultsThe study cohort comprised 88 585 patients (45 074 male; median age, 71.0 years [range, 1.0-104.0 years]) with malignant neoplasms who presented to a health care institution with a diagnosis of acute lower extremity DVT. Of these patients, 33 740 (38.1%) underwent IVC filter placement; patients with risk factors such as upper gastrointestinal bleeding (odds ratio, 1.32; 95% CI, 1.29-1.37), intracranial hemorrhage (odds ratio, 1.21; 95% CI, 1.19-1.24), and coagulopathy (odds ratio, 1.09; 95% CI, 1.08-1.10) were more likely to receive an IVC filter. A total of 4492 patients (5.1%) developed a new PE after their initial DVT diagnosis. There was a significant improvement in PE-free survival for these patients compared with those who did not receive IVC filters across the full, unbalanced study cohort as well as after propensity score matching and competing risk analysis (hazard ratio, 0.69; 95% CI, 0.64-0.75; P < .001). Furthermore, IVC filter placement reduced the development of PE in patients with very high-risk malignant neoplasms (eg, pancreaticobiliary cancer), high-risk malignant neoplasms (eg, lung cancer), and low-risk malignant neoplasms (eg, prostate cancer). After accounting for anticoagulation use and imbalanced risk factors, IVC filter placement did not increase the risk of new DVT development.Conclusions and relevanceThis study suggests that, for patients with cancer and DVT and bleeding risk factors, IVC filter placement is associated with an increased rate of PE-free survival.
