Ji Y, Qin Y, Tan Q, Qiu Y, Han S, Qi X. Development of a chemiluminescence assay for tissue plasminogen activator inhibitor complex and its applicability to gastric cancer. BMC Biotechnol 2024; 24:30. [PMID: 38720310 PMCID: PMC11080135 DOI: 10.1186/s12896-024-00850-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 04/17/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND Venous thromboembolism (VTE), is a noteworthy complication in individuals with gastric cancer, but the current diagnosis and treatment methods lack accuracy. In this study, we developed a t-PAIC chemiluminescence kit and employed chemiluminescence to detect the tissue plasminogen activator inhibitor complex (t-PAIC), thrombin-antithrombin III complex (TAT), plasmin-α2-plasmin inhibitor complex (PIC) and thrombomodulin (TM), combined with D-dimer and fibrin degradation products (FDP), to investigate their diagnostic potential for venous thrombosis in gastric cancer patients. The study assessed variations in six indicators among gastric cancer patients at different stages. RESULTS The t-PAIC reagent showed LOD is 1.2 ng/mL and a linear factor R greater than 0.99. The reagents demonstrated accurate results, with all accuracy deviations being within 5%. The intra-batch and inter-batch CVs for the t-PAIC reagent were both within 8%. The correlation coefficient R between this method and Sysmex was 0.979. Gastric cancer patients exhibited elevated levels of TAT, PIC, TM, D-D, FDP compared to the healthy population, while no significant difference was observed in t-PAIC. In the staging of gastric cancer, patients in III-IV stages exhibit higher levels of the six markers compared to those in I-II stages. The ROC curve indicates an enhancement in sensitivity and specificity of the combined diagnosis of four or six indicators. CONCLUSION Our chemiluminescence assay performs comparably to Sysmex's method and at a reduced cost. The use of multiple markers, including t-PAIC, TM, TAT, PIC, D-D, and FDP, is superior to the use of single markers for diagnosing VTE in patients with malignant tumors. Gastric cancer patients should be screened for the six markers to facilitate proactive prophylaxis, determine the most appropriate treatment timing, ameliorate their prognosis, decrease the occurrence of venous thrombosis and mortality, and extend their survival.

Abstract
Objective To investigated the clinical efficacy of Soluble thrombomodulin (sTM), tissue
plasminogen activator inhibitor complex (t-PAI·C),thrombin-antithrombin
complex (TAT),α2-plasmininhibitor-plasmin complex (PIC) in pediatric sepsis
and pediatrics sepsis-induced coagulopathy (pSIC). Methods We prospectively collected patient data with sepsis diagnosed in the PICU of
Shanghai Children's Medical Center from June 2019 to June 2021. sTM,t-PAI·C,
TAT,PIC and classical coagulation laboratory tests (CCTs) were evaluated on
the day of sepsis diagnosis. Results Fifty-nine children were enrolled, There were significant differences in
t-PAI·C (P = 0.001), Plt (P < 0.001), PT (P < 0.001), INR (P <
0.001), aPTT (P < 0.001), and TT (P = 0.048) between the pSIC and
non-pSIC groups, logistic regression analysis showed that Plt (P = 0.032)
was an independent risk factor for pSIC. Logistic regression analysis showed
that sTM (P = 0.007) and Plt (P = 0.016) were independent risk factors for
the outcome in pediatrics sepsis following discharge. The AUC of sTM
combined with Plt on the mortality outcome of children with sepsis at
discharge was 0.889 (95%CI: 0.781,0.956). which was better than that for
PRISM III (AUC, 0.723), pSOFA (AUC, 0.764), and blood Lac (AUC, 0.717) when
sepsis was diagnosed in the PICU. Conclusions The t-PAI·C increased in children with pSIC. The prediction of sepsis outcome
using sTM combined with Plt was better than with PRISM III, pSOFA, or
Lac.Further research is still needed in the future to explore the clinical
value of sTM, TAT, PIC, and t-PAI·C in diagnosis and outcome of pediatrics
sepsis and pSIC.

Abstract
Background. Plasminogen activator inhibitor-1(PAI-1) is a marker of endothelial dysfunction(ED) and a predictor of both the development of type 2 diabetes mellitus, and a cardiovascular event(CVE). Its role in the CVE development was sufficiently studied in patients without carbohydrate metabolism disorders, and understudied in patients with prediabetes.
Aim: the research interest is the study of PAI-1 in patients with prediabetes and its effect on the CVE development.
Materials and methods. The case-control study of 168 patients aged from 18 to 65 was carried out among the local population from January to December 2019.After clinical examination, patients were divided into 3 groups: group 1 (n=55)– patients with prediabetes and with CVE; group 2 (n=93) - patients with prediabetes and without CVE; the control group n=20.
Results. Differences in PAI-1 level were found in groups 1 (Me=30718.6 pg/ml) and 2 (Me=24692.0 pg/ml; p≤0.001), even greater differences were found in both groups compared to the control one (p≤0.001).
The correlation analysis has found in both group influence such IR indicators as fasting glucose, IR-HOMA index, glucagon, C-peptide to elevation of PAI-1. These findings indicate that with an elevation of the PAI-1 level, the concentration of fasting glucose, glucagon, C-peptide and scores of IR-HOMA index increase in both group.
The Binary regression analysis has demonstrated, that an elevation of the PAI-1 biomarker increases the likelihood of CVE by 3.3 fold in patients with prediabetes (p≤0.01). In addition to, a model has been derived for assessing the risk of cardiovascular events in patients with prediabetes.
Conclusions. Elevation of PAI-1 concentration is associated with insulin resistance which leads to ED, and further development risk of CVE in patients with prediabetes.

Abstract
The increasing burden of obesity plays an essential role in increased cardiovascular morbidity and mortality. The effects of obesity on the cardiovascular system have also been demonstrated in childhood, where prevention is even more important. Obesity is associated with hormonal changes and vascular dysfunction, which eventually lead to hypertension, hyperinsulinemia, chronic kidney disease, dyslipidemia and cardiac dysfunction—all associated with increased cardiovascular risk, leading to potential cardiovascular events in early adulthood. Several preventive strategies are being implemented to reduce the cardiovascular burden in children. This paper presents a comprehensive review of obesity-associated cardiovascular morbidity with the preventive diagnostic workup at our hospital and possible interventions in children.

Abstract
AIMS Plasminogen activator inhibitor-1 (PAI-1), traditionally associated with fibrinolysis, is increasingly implicated in impaired vascular function. However, studies on its association with microvascular function are limited to the cutaneous and coronary microvascular beds in older and diseased individuals. To better understand its potential involvement in the early stages of disease development, we investigated the associations of retinal vasodilatory responses to flicker light with PAI-1 activity (PAI-1act) in young and healthy individuals. METHODS We included healthy Black and White women and men (n = 518; aged 20-30 years), and measured plasma PAI-1act and retinal vasodilatory responses to flicker light provocation. We also collected demographic and lifestyle data, measured blood pressure, anthropometry, blood lipids, inflammatory and other biomarkers. RESULTS In multivariate regression analyses, maximal retinal venular dilation associated independently and inversely with PAI-1act (adj. R2 = 0.11; β = -0.15; p = 0.001) in the total group. In exploratory subgroup analyses, this association remained in White women (adj. R2 = 0.07; β = -0.23; p = 0.005), and was more robust with younger age and lower blood pressure and in non-smokers, but also with greater central adiposity, higher low-density lipoprotein cholesterol and inflammation (all p < 0.05). CONCLUSIONS Our data suggest that in young individuals, PAI-1 may already be associated with subclinical microvascular dysfunction.

Clin Appl Thromb Hemost 2020; 26:1076029620971041. [PMID: 33141604 PMCID: PMC7649926 DOI: 10.1177/1076029620971041] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 10/05/2020] [Accepted: 10/13/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Venous thromboembolism (VTE) is an important complication in patients with malignant tumors. Its exact diagnosis and treatment are still lacking. We used a high-sensitive chemiluminescence method to detect thrombin-antithrombin III complex (TAT), plasmin-α2-plasmininhibitor complex (PIC), thrombomodulin (TM), and tissue plasminogen activator-inhibitor complex(t-PAIC) in combination with D-dimer and fibrin degradation product (FDP) to analyze their diagnostic and prognostic value in patients with malignant tumors. METHODS In total, 870 patients with confirmed malignant tumors were included, 82 of whom had diagnosed VTE; 200 healthy individuals were classified as the control group. The TAT, PIC, TM, and t-PAIC were detected using Sysmex HISCL5000 automated analyzers, whereas FDP and D-dimer were detected using Sysmex CS5100 coagulation analyzer. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic efficiency. Survival probabilities were determined using Kaplan-Meier analysis, and multivariate analyses were performed using a Cox regression model. RESULTS Compared with healthy controls, patients with malignant tumors showed significantly elevated TAT, PIC, TM, t-PAIC, D-dimer, and FDP. Similarly, compared with patients in the non-thrombosis group, those in the thrombosis group showed significantly elevated levels of the above mentioned markers. Logistic regression analysis showed that TAT, PIC, TM, t-PAIC, D-Dimer, and FDP were all associated with VTE. ROC analysis showed that "TAT+PIC+TM+t-PAIC+D-dimer+FDP"showed the highest sensitivity and specificity. Patients with elevated TAT, PIC, TM, and t-PAIC had a significantly shorter survival. Multivariate Cox survival analysis showed that TM and t-PAIC were significantly associated with poor prognosis. In addition, the incidence of VTE was significantly lower in patients with malignant tumors who were treated with low-molecular-weight heparin (LMWH), and their survival period was significantly longer than that of patients with malignant tumors who were not treated with LMWH. CONCLUSION TAT, PIC, TM, and t-PAIC combined with D-dimer and FDP were better than the application of a single marker in the diagnosis of VTE in patients with malignant tumors. TAT and PIC can be used as sensitive markers in the diagnosis of VTE but not as prognostic markers. TM and t-PAIC might be independent prognostic indicators in patients with malignant tumors, regardless of the state of thrombus.

Abstract
AIMS This study was aimed to compare insulin sensitivity and secretion response, lipoprotein and plasminogen activator inhibitor 1 (PAI-1) levels between the subjects with and without coronary artery endothelial dysfunction (ED). METHODS ED was detected by intracoronary injection of acetylcholine (ACh) in 47 nondiabetes subjects without stenotic coronary arteries, selected from 316 consecutive patients with coronary angiography performed for suspected coronary artery disease. The subjects were divided into two groups: presence of ACh-induced coronary spasm (group ED+, N = 30) and absence of ACh-induced coronary spasm (group ED-, N = 17). Insulin sensitivity (Si) was evaluated by frequently sampled intravenous glucose tolerance test (FSIGTT) with minimal model analysis and by HOMA-IR, insulin secretion by acute insulin response (AIR) (calculated from the first 8 min of FSIGTT) and by disposition index (DI) (Si × AIR). Lipids and PAI-1 levels were determined enzymatically, and LDL particle size by gradient gel electrophoresis. RESULTS Si was significantly lower (4.22 ± 0.62 vs 6.98 ± 1.47 min-1/mU/l × 104; p < 0.05) while HOMA-IR was significantly higher in ED + group vs ED- group (2.8 ± 0.3 vs 1.7 ± 0.2; p < 0.05). Simultaneously, AIR and DI was significantly lower in ED + vs ED- groups (p < 0.05 and p < 0.01, respectively). Investigated groups did not differ in fasting lipid levels but ED+ group had significantly smaller LDL particles (p < 0.01) and higher PAI-1 levels (p < 0.05). Regression analysis shown that DI was a strong independent predictor of appearance of ED, together with PAI-1 and LDL particle size. CONCLUSIONS Both insulin resistance and impairment in insulin secretion response strongly correlate with coronary ED in subjects without diabetes.

Association of lecithin-cholesterol acyltransferase activity measured as a serum cholesterol esterification rate and low-density lipoprotein heterogeneity with cardiovascular risk: a cross-sectional study. Heart Vessels 2015; 31:831-40. [PMID: 25894629 DOI: 10.1007/s00380-015-0678-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2014] [Accepted: 04/03/2015] [Indexed: 10/23/2022]
Abstract
The cholesterol-esterifying enzyme, lecithin-cholesterol acyltransferase (LCAT), is believed to play a key role in reverse cholesterol transport. However, recent investigations have demonstrated that higher LCAT activity levels increase the formation of triglyceride (TG)-rich lipoproteins (TRLs) and atherogenesis. We hypothesized that higher LCAT activity measured as a serum cholesterol esterification rate by the endogenous substrate method might increase the formation of TRLs and thereby alter low-density lipoprotein (LDL) heterogeneity. The estimated LDL particle size [relative LDL migration (LDL-Rm)] was measured by polyacrylamide gel electrophoresis with the LipoPhor system (Joko, Tokyo, Japan) in 538 consecutive patients with at least risk factor for atherosclerosis. Multivariate regression analysis after adjustments for traditional risk factors identified elevated TRL-related marker (TG, remnant-like particle cholesterol, apolipoprotein C-II, and apolipoprotein C-III) levels as independent predictors of smaller-sized LDL particle size, both in the overall subject population and in the subset of patients with serum LDL cholesterol levels of <100 mg/dL. Area under the receiver operating characteristic curve of the LCAT activity (0.79; sensitivity 60 %; specificity 84.8 %) was observed for the evaluation of the indicators of an LDL-Rm value of ≥0.40, which suggests the presence of large amounts of small-dense LDL. The results lend support to the hypothesis that increased LCAT activity may be associated with increased formation of TRLs, leading to a reduction in LDL particle size. Therefore, to reduce the risk of atherosclerotic cardiovascular disease, it may be of importance to pay attention not only to a quantitative change in the serum LDL-C, but also to the LCAT activity which is possibly associated with LDL heterogeneity.

Abstract
This study was aimed at investigating daily fluctuation of PAI-1 levels in relation to insulin resistance (IR) and daily profile of plasma insulin and glucose levels in 26 type 2 diabetic (T2D) patients with coronary artery disease (CAD) (group A), 10 T2D patients without CAD (group B), 12 nondiabetics with CAD (group C), and 12 healthy controls (group D). The percentage of PAI-1 decrease was lower in group A versus group B (4.4 ± 2.7 versus 35.0 ± 5.4%; P < 0.05) and in C versus D (14.0 ± 5.8 versus 44.7 ± 3.1%; P < 0.001). HOMA-IR was higher in group A versus group B (P < 0.05) and in C versus D (P < 0.01). Simultaneously, AUCs of PAI-1 and insulin were higher in group A versus group B (P < 0.05) and in C versus D (P < 0.01), while AUC of glucose did not differ between groups. In multiple regression analysis waist-to-hip ratio and AUC of insulin were independent determinants of decrease in PAI-1. The altered diurnal fluctuation of PAI-1, especially in T2D with CAD, might be strongly influenced by a prolonged exposure to hyperinsulinemia in the settings of increased IR and abdominal obesity, facilitating altogether an accelerated atherosclerosis.

Abstract
Two patients after Kawasaki disease (KD) developed acute myocardial infarction in their thirties, though coronary artery follow-up were deemed unnecessary because of apparently angiographic normal coronary arteries in their children more than 1-year after acute KD. Angiographic findings of apparently normal coronary arteries in the late period after acute KD are possible to mislead their prognoses. It should be recognized that coronary aneurysms can often regress in the late period. There is ongoing controversy about the therapeutic strategy in patients whose coronary aneurysms regressed within several years after acute KD. Coronary computed tomography angiography and flow-mediated dilatation might be useful for the detection of mild sequelae of KD non-invasively.

Monocytes expand with immune dysregulation and is associated with insulin resistance in older individuals with chronic HIV. PLoS One 2014; 9:e90330.

Abstract
Background Rates of insulin resistance are increased in HIV-infected patients on stable antiretroviral therapy (ART). Such increase may partially be due to HIV-induced immune dysregulation involving monocytes (MO) and its subsets. Materials and Methods Cross-sectional analysis of 141 HIV-infected subjects age ≥ 40 years on stable ART. Homeostatic model assessment–insulin resistance (HOMA-IR) and rates of metabolic syndrome were calculated. Subjects were classified by fasting glucose and oral glucose tolerance test (OGTT) into clinical diabetes categories. Multi-parametric flow cytometry was used to determine MO subset percentages: [classical (CD14++CD16−), intermediate (CD14++CD16+), non-classical (CD14low/+CD16++), and a recently identified fourth (CD14low/+CD16−) ‘transitional’ MO subset] and percentage of activated (CD38+HLA-DR+) CD8 T cells. Absolute levels of cells were calculated using clinical CBC and T cell subset data. Multiple plasma soluble biomarkers were assessed by Luminex technology. Results Median age 50 years, CD4 count (percent) 505 cells/µL (29%), and 89% male. Total MO (r = −0.23, p = 0.006) and classical and non-classical MO subsets correlated negatively with CD4 percent. No correlations were seen with CD4 count as absolute values. Log-total MO and log-classical MO predicted HOMA-IR independently of HIV immuno-virologic and diabetes risk factors (β = 0.42, p = 0.02 and β = 0.35, p = 0.02, respectively) and were increased in subjects with metabolic syndrome (p = 0.03 and p = 0.05 respectively). Total and/or subset MO levels correlated with multiple soluble plasma biomarkers including CRP, IL-6, MMP-9, MPO, SAA, SAP and tPAI-1, with tPAI-1 independently predicting HOMA-IR (β = 0.74, p<0.001). Conclusions MO levels increase with worsening HIV immune dysregulation as assessed by CD4 percent. CD4 percent may provide additional information about MO and metabolic risk in this population beyond absolute values. MO, and specifically classical MO, may contribute to insulin resistance and metabolic syndrome during chronic HIV infection. Multiple soluble plasma biomarkers including tPAI-1 increase with increase in MO. Levels of tPAI-1 independently predict the development of insulin resistance.
