Pentraxin-3 Levels In Patients Research Articles

Pentraxin-3 is a novel marker for the diagnosis of endometriosis

Introduction: Endometriosis is one of the most common reproductive disorders affecting women. The pathophysiology of endometriosis is also quite complicated, and many mechanisms have been put forward. Pentraxin-3 is a glycoprotein released by leukocyte and myeloid dendritic cells in peripheral blood with the stimulation of some cytokines, especially IL-1 and TNF-α, Toll-Like Receptor agonists, or microbial components. It has been shown that pentraxin-3 is also released from ectopic endometrial cells. The aim of this study is to investigate serum pentraxin-3 levels and their correlation with endometriosis in women with endometriosis and healthy women without endometriosis. Methods: This case-control study evaluated patients diagnosed with endometriosis based on imaging techniques or laparoscopy between 2018 and 2020. Serum samples of 71 patients who had been diagnosed with endometriosis as a case group and 56 healthy patients who had undergone laparoscopic tubal ligation and were proven to be endometriosis-free as a control group were compared for pentraxin-3 level. Results: Serum pentraxin-3 level was significantly higher in the endometriosis group compared with the control group ( p < 0.05). Parity and gravida were significantly higher in the control group than in the endometriosis group. When patients with endometriosis surgery history were excluded, there was no significant change in serum pentraxin-3 levels in patients with medical treatment for endometriosis ( p > 0.05). Both the sensitivity and specificity of serum pentraxin-3 were 73.2%. Conclusions: These results demonstrate a relationship between serum pentraxin-3 and endometriosis. Serum pentraxin-3 might be used as a non-invasive method for the diagnosis of endometriosis.

The potential diagnostic value of serum pentraxin-3 in hepatocellular carcinoma in Egyptian patients

Background and aimHepatocellular carcinoma (HCC) is considered one of the most common cancers in the world and one of the principal causes of cancer-linked deaths. Therefore, identification of new biomarkers for diagnosis, especially early diagnosis of HCC, is very important. Pentraxin 3 (PTX3) is possibly involved in cancer development, and as regard to liver diseases, plasma PTX3 was implicated to be associated with HCC occurrence. Therefore, this study will determine the serum PTX3 levels in patients with cirrhosis and HCC and to assess the potential diagnostic value in HCC in Egyptian patients.ResultsPentraxin 3 was significantly higher in HCC patients than in cirrhotic patients (p < 0.001); also, serum PTX3 was significantly correlated with number, size of focal lesions, the presence of portal vein thrombosis, and BCLC staging (p < 0.001).ConclusionThe significant increased levels of serum pentraxin 3 in HCC may support its use as an early marker for HCC, either alone or in combination with serum alpha-fetoprotein (AFP), allowing early diagnosis and prompt intervention.

Plasma Levels of Pentraxin 3: A Potential Prognostic Biomarker in Urinary Bladder Cancer Patients.

Urinary bladder cancer (BC) represents a major health issue, and identifying novel biomarkers for early disease detection and outcome prediction is paramount. It has already been established that the immune system plays a role in tumour initiation and progression in which the inflammatory marker pentraxin 3 (PTX3) might be involved, presenting a variety of functions in different cancers. The aim of this study was to investigate whether plasma levels of PTX3 could be used as a biomarker for patients with BC. Plasma levels of PTX3 were determined in 118 BC patients and 50 controls by ELISA. Patients with BC had significantly higher PTX3 levels compared to controls. The value as a diagnostic biomarker is probably limited, however, since no significant difference in PTX3 levels was seen between patients with non-muscle-invasive BC and controls; they were seen only between patients with muscle-invasive disease and controls. However, the potential value of PTX3 as a prognostic biomarker was indicated by significantly higher PTX3 levels in patients who developed metastatic disease during follow-up compared to patients who did not develop metastatic disease. The conclusions from this study are that plasma levels of PTX3 have limited value as a diagnostic biomarker, although they have potential as a prognostic biomarker for patients with BC.

Association Between Dipeptidyl Peptidase-4 Inhibitor Use and Cognitive Functions, Brain-Derived Neurotrophic Factor, and Pentraxin-3 Levels in Patients With Type 2 Diabetes.

Background Diabetes mellitus is an important risk factor for dementia, Alzheimer's disease, and other neurodegenerative diseases. Recent findings have made the relationship between the inhibition of the dipeptidyl peptidase-4 (DPP-4) enzyme and cognitive functions an important research topic. Objective This study aimed to evaluate the association between DPP-4 inhibitor use and cognitive functions, serum brain-derived neurotrophic factor (BDNF), and pentraxin-3 (PTX-3) levels in patients with type 2 diabetes, compared with the patients who only use metformin treatment. Design, patients, and methods A total of 50 patients with type 2 diabetes (hemoglobin A1c levels at ≤%7.5) who were under treatment with metformin±DPP-4 inhibitor (n=25) or only metformin (n=25) were included in this cross-sectional study. Serum BDNF and PTX-3 levels were assessed using an enzyme-linked immunosorbent assay.A standardized mini-mental test (sMMSE) was used to evaluate cognitive functions. Results There were no significant differences in the characteristics of the study groups. The mean sMMSE score of the patients receiving DPP-4±metformin treatment was statistically higher when compared with patients receiving only metformin treatment (27.16±1.95 vs. 25.40±3.07; p=0.041). The BDNF levels of the patients receiving DPP-4±metformin treatment were considerably higher than the patients receiving only metformin treatment (394.51±205.66 ng/ml vs. 180.63±297.94 ng/ml; p=0.001). The difference in PTX-3 levels between study groups was not statistically significant (5.47±3.44 vs. 3.79±2.53; p=0.055). Conclusion When compared to metformin alone, the use of DPP-4 inhibitors in the treatment of patients with type 2 diabetes was associated with increased serum BDNF levels and improved cognitive functions.

Long pentraxin 3 (PTX3) levels predict death, intubation and thrombotic events among hospitalized patients with COVID-19.

PTX3 is an important mediator of inflammation and innate immunity. We aimed at assessing its prognostic value in a large cohort of patients hospitalized with COVID-19. Levels of PTX3 were measured in 152 patients hospitalized with COVID-19 at San Gerardo Hospital (Monza, Italy) since March 2020. Cox regression was used to identify predictors of time from admission to in-hospital death or mechanical ventilation. Crude incidences of death were compared between patients with PTX3 levels higher or lower than the best cut-off estimated with the Maximally Selected Rank Statistics Method. Upon admission, 22% of the patients required no oxygen, 46% low-flow oxygen, 30% high-flow nasal cannula or CPAP-helmet and 3% MV. Median level of PTX3 was 21.7 (IQR: 13.5-58.23) ng/ml. In-hospital mortality was 25% (38 deaths); 13 patients (8.6%) underwent MV. PTX3 was associated with risk of death (per 10 ng/ml, HR 1.08; 95%CI 1.04-1.11; P<0.001) and death/MV (HR 1.04; 95%CI 1.01-1.07; P=0.011), independently of other predictors of in-hospital mortality, including age, Charlson Comorbidity Index, D-dimer and C-reactive protein (CRP). Patients with PTX3 levels above the optimal cut-off of 39.32 ng/ml had significantly higher mortality than the others (55% vs 8%, P<0.001). Higher PTX3 plasma levels were found in 14 patients with subsequent thrombotic complications (median [IQR]: 51.4 [24.6-94.4] versus 21 [13.4-55.2]; P=0.049). High PTX3 levels in patients hospitalized with COVID-19 are associated with a worse outcome. The evaluation of this marker could be useful in prognostic stratification and identification of patients who could benefit from immunomodulant therapy.

Utility of Pentraxin-3 as a biomarker for diagnosis of acute appendicitis: a systematic review and meta-analysis

PurposeTo systematically summarize all relevant data and to define the current evidence on the utility of Pentraxin-3 (PTX3) as a biomarker for acute appendicitis (AA) in children.MethodsThis review was conducted in accordance with the PRISMA guidelines. PubMed, Embase, Scopus, and Web of Science databases were systematically searched for studies comparing the levels of PTX3 in patients with AA vs healthy controls or non-specific abdominal pain (NSAP). Mean differences were calculated for all outcomes and the inverse variance method was used for weighted mean difference. The methodological quality of the included studies was assessed using the Downs and Black scale.ResultsFive comparative studies were included. Significantly elevated levels of PTX3 in cases with AA vs healthy controls (WMD: 9.56, 95% CI 7.24–11.88, p < 0.00001), and patients with AA vs NSAP (WMD: 8.05, 95% CI 6.81–9.29, p < 0.00001) were demonstrated. Similarly, in separate meta-analyses, the levels of PTX3 were significantly elevated in children with AA vs healthy controls (WMD: 11.18, 95% CI 10.03–12.34, p < 0.00001), and children with AA vs NSAP (WMD: 8.35, 95% CI 6.88–9.82, p < 0.00001).ConclusionsPTX3-levels are elevated in AA, but differentiation between perforated and non-perforated appendicitis demands other methods.

Evaluation of the clinical significance of serum pentraxin-3 levels in patients with polycystic ovary syndrome

Background: Polycystic ovary syndrome (PCOS) is commonly associated with insulin resistance (IR), hyperinsulinemia, and dyslipidemia, which play a role in the development of endothelial dysfunction and promote the early onset of cardiovascular diseases. The aim of this study was to evaluate the clinical importance of pentraxin-3 levels in PCOS patients. Methods: Forty-five female patients diagnosed with PCOS according to the 2003 Rotterdam criteria and 42 healthy women were included in the study. All women studied were tested within 3 and 5 days of their menstrual cycle. Ultrasonographic evaluation of each patient was first conducted using the suprapubic method. Serum PTX-3, endothelin 1 (ET-1), vascular cell adhesion molecule 1 (VCAM-1), intercellular adhesion molecule 1 (ICAM-1), and nitric oxide levels were measured using the enzyme-linked immunosorbent assay method. Results: Pentraxine-3 (PTX-3) levels in the patient group were significantly lower than those in the control group (p &lt; 0.05). PTX-3 levels in the group with hirsutism were significantly higher than those in the nonhirsutism group (p &lt; 0.05). Homeostatic model assessment for IR (HOMA-IR) levels in the patient group were significantly higher than those in the control group (p &lt; 0.01). A weak negative correlation was found between PTX-3 and HbA1c levels. The accuracy rate of the PTX-3 test in distinguishing patients and nonpatients was moderate with a 0.634 area-under-the-curve value. Conclusions: During the follow-up of patients with PCOS, a decrease in serum PTX-3 levels associated with hirsutism and IR may be observed.

PENTRAXIN 3 LEVELS CORRELATE WELL WITH DISEASE SEVERITY AT ADMISSION IN COVID-19 PATIENTS.

Pentraxin 3 (PTX3), a long pentraxin, is not only released from dendritic cells and neutrophils but also from epithelial and endothelial cells such as alveolar epithelium. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) initially activates the innate immune system, causing a complex immune response. Clinical and experimental studies suggest that PTX3, a locally and systemically secreted marker, can be used as a predictor of the severity and mortality in respiratory infections. In the current study, serum PTX3 levels in patients hospitalized with COVID-19 were found to be significantly increased at admission and showed significant association with the disease severity.

Evaluation of Serum Pentraxin-3 Level in Patients with Acute Myocardial Infarction Compared with Control Group

Background & Objective:The aim of this study was to measure serum pentraxin 3 (PTX3) in patients with acute myocardial infarction (MI) and compare it with the control group.Methods:In this case-control study, 60 patients with MI (±ST-segment elevation) were included in the case group , and those with symptoms suspicious for coronary artery disease (CAD) and with no abnormal findings in angiography and troponin I level less than 99th percentile of normal population were included as a control group (N=30). Serum PTX3 and troponin I were measured.Results: In this study, 60 patients including 34 men and 26 women were included in the case group (mean age: 61.4±8.86 years in non–ST-segment elevation myocardial infarction [NSTEMI] subgroup and mean age: 57.9±9.49 years in ST-segment elevation myocardial infarction [STEMI] subgroup), as well as 13 men and 17 women as the control group (mean age: 55.47±10.09 years). PTX3 level was higher in MI cases (1128.4±1205 pg/mL) compared to controls (394.5±170.40 pg/mL) (P=0.001). There was no relationship between ejection fraction (EF) and PTX3 level in the MI group. The area under the ROC curve (AUC) of PTX3 in MI was presented by 0.828 (AUC=0.828) (P>0.001). We defined three different cutoffs for PTX in this study, in which the cutoff ≥400 pg/mL had the highest sensitivity (92%), and the cutoff ≥700 pg/mL had the highest specificity (97%). Conclusion:According to the results of this study, PTX3 as an inflammatory marker showed higher level in patients with MI, especially in STEMI cases. Therefore, combined evaluation of troponin I and PTX3 levels would be associated with more accuracy in diagnosis of MI.

Therefore, combined evaluation of troponin I and PTX3 levels would be associated with more accuracy in diagnosis of MI.

Macrophage expression and prognostic significance of the long pentraxin PTX3 in COVID-19.

Long pentraxin 3 (PTX3) is an essential component of humoral innate immunity, involved in resistance to selected pathogens and in the regulation of inflammation1-3. The present study was designed to assess the presence and significance of PTX3 in Coronavirus Disease 2019 (COVID-19)4-7. RNA-sequencing analysis of peripheral blood mononuclear cells, single-cell bioinformatics analysis and immunohistochemistry of lung autopsy samples revealed that myelomonocytic cells and endothelial cells express high levels of PTX3 in patients with COVID-19. Increased plasma concentrations of PTX3 were detected in 96 patients with COVID-19. PTX3 emerged as a strong independent predictor of 28-d mortality in multivariable analysis, better than conventional markers of inflammation, in hospitalized patients with COVID-19. The prognostic significance of PTX3 abundance for mortality was confirmed in a second independent cohort (54 patients). Thus, circulating and lung myelomonocytic cells and endothelial cells are a major source of PTX3, and PTX3 plasma concentration can serve as an independent strong prognostic indicator of short-term mortality in COVID-19.

New Insights into Diabetic and Vision-Threatening Retinopathy: Importance of Plasma Long Pentraxine 3 and Taurine Levels

ABSTRACT Purpose To investigate diabetic retinopathy (DR), plasma long pentraxin-3 (PTX-3) and taurine levels, and systemic factors in patients with type 2 diabetes mellitus (DM). Materials and Methods Patients with type 2 DM were categorized based on the presence of DR and maculopathy. Retinal findings (retinopathy, maculopathy, flame-shaped hemorrhage, intraretinal microvascular abnormalities, neovascularization of the optic disc, neovascularization elsewhere, and soft exudate); laboratory findings (fasting blood glucose, glycosylated hemoglobin [HbA1c], Taurine, PTX-3); systolic blood pressure (SBP) and diastolic blood pressure (DBP) were analyzed. Results In this study, 39 patients with a mean age of 59.5 ± 8.1 years were included. The mean taurine level was significantly lower (p = .025) and HbA1c values were significantly higher (p = .0001) in patients with and without DR, respectively. In patients with varying severity of DR, a significant difference in the plasma taurine level was found (p = .0001). The mean PTX-3 level decreased with the severity of retinopathy; however, there was no significant difference in levels among the grading groups (p = .732). Taurine and PTX-3 levels were significantly lower in patients with maculopathy (p = .001 and p = .022, respectively) and significantly higher in patients with grade 0 maculopathy than in those with grade 1, 2, or 3 maculopathy (p = .023, p = .01, and p = .01, respectively). Patients with flame-shaped hemorrhage had significantly lower PTX-3 levels (p = .009) and higher SBP and DBP levels (p = .003, p = .023) than those without the hemorrhage. Conclusions No significant relation between PTX-3 level and severity of DR was found. HbA1c, taurine, and PTX-3 levels in patients with vision-threatening DR symptoms were significantly different from those without these symptoms. Management of systemic blood pressure and glycemic control is mandatory in the follow-up of DR, and increasing the plasma taurine levels can prevent vision loss.

Elevated serum pentraxin 3 levels might predict the diagnosis of branch atheromatous disease at a very early stage.

Branch atheromatous disease (BAD) is one of the stroke subtypes caused by occlusion at the origin of a deep penetrating artery of the brain and is associated with a microatheroma or a junctional plaque. Patients with BAD often develop progressive worsening of neurologic deficits, although these patients often present minor stroke with clinical characteristics of lacunar syndrome at the onset. Pentraxin 3 (PTX3) is known to be a key molecule involved in the pathogenesis of atherosclerosis. Although a high level of serum PTX3 is observed in patients with acute coronary syndrome, there are no reports on PTX3 levels in patients with BAD. This study aimed to investigate whether serum PTX3 levels can distinguish BAD from other stroke subtypes. We investigated 93 patients with ischaemic stroke. Serum PTX3 levels on admission were measured using enzyme-linked immunosorbent assay in patients with BAD and those with other stroke subtypes (each n≥20). The median PTX3 levels in patients with BAD (4840pg/mL) were higher than those with other subtypes of stroke (3397pg/mL in lacunar stroke, 1298pg/mL in large-artery atherosclerosis, 1470pg/mL in cardioaortic embolism and 1006pg/mL in control) (all P<0.01). Our results suggest that elevated serum PTX3 levels might predict the diagnosis of BAD at a very early stage.

Determination of pentraxin 3 levels in cerebrospinal fluid during central nervous system infections.

Pentraxin 3 (PTX3) is an acute phase protein; its plasmatic levels significantly rise during severe infections. Data on PTX3 levels in cerebrospinal fluid (CSF) of patients with central nervous system (CNS) infections are lacking. We aimed (a) to assess the diagnostic potential of measuring CSF PTX3 levels in patients with CNS infections and (b) to establish CSF PTX3 cutoffs to distinguish between bacterial and aseptic meningoencephalitis (ROC curve). PTX3 levels were measured in CSF from 19 patients admitted to Trieste Hospital, Italy, with CNS infection. A diagnosis of bacterial infection and aseptic meningoencephalitis was made in 7 (37%) and 12 (63%) patients, respectively. Subjects with bacterial infections showed significantly higher PTX3 levels (13.5 vs 1.27ng/mL in aseptic meningoencephalitis, p = 0.010). We identified two different CSF PTX3 levels cutoffs. (1) The best cutoff to maximise Youden's J was 9.6ng/mL with a sensitivity, specificity, positive predictive value and negative predictive value (NPV) of 71.4%, 91.4%, 83.3%, 84.6%, respectively. (2) The cutoff with higher NPV (100%) was 3.6ng/mL; a diagnosis of bacterial infections was obtained in 0% patients with CSF PTX3 levels < 3.6ng/mL vs 58% of those with CSF PTX3 levels ≥ 3.6ng/mL (p = 0.017). CSF PTX3 levels are higher in bacterial meningitis than aseptic meningoencephalitis. A cutoff of 3.6ng/mL of CSF PTX3 has a high NPV and can be used to exclude bacterial CNS infections.

Pentraxin-3 diagnostic value and its association with clinical types of coronary artery disease in patients with concomitant diabetes melitus type 2

Summary. Great attention is paid recently to studying of coronary artery disease (CAD) pathogenesis on the background of diabetes mellitus (DM). One of the pathogenetic mechanisms of atherosclerosis is generalized or chronic inflammation. In particular, the question of the role of an inflammatory component role in development of atherosclerosis in patients with DM 2 types is studied. One of new perspective markers of immune inflammation is pentraxin-3 (PTX-3). The purpose of the study –to evaluate the diagnostic value of pentraxin-3 and to study the relationship with the clinical types of coronary heart disease in patients with concomitant type 2 diabetes mellitus. Material and methods. The comprehensive examination of 110 patients with CAD was conducted. Patients were divided into groups depending on presence of DM type 2: the first group included 75 patients with stable CAD and DM type 2, the group of comparison consisted of 35 patients with CAD without DM type 2.Also patients were distributed in groups depending on the IHD clinical form: stable stenocardia, post-infarct cardiosclerosis (PIC) and diffusive cardiosclerosis. Results. In patients with CAD with concomitant DM type 2 there was defined pentraxinemia level depending on clinical types of CAD: in patients with PIC the PTX-3 level in blood serum was 5.68±0.51 ng/ml (r&lt;0.05). In patients with stable stenocardia the PTX-3 level was 6.18±0.49 ng/ml (r&lt;0.05). In patients with diffusive cardiosclerosis the PTX-3 level was 4.92±0.47 ng/ml (r&lt;0.05). Pentraxinemia level in patients with CAD without DM type 2 depending on clinical types of CAD was defined as follows: in patients with PIC the PTX-3 level in blood serum constituted 3.76±0.51 ng/ml (r&lt;0.05). In patients with stable stenocardia the PTX-3 level was 4.18±0.39 ng/ml (r&lt;0.05). In patients with a diffusive cardiosclerosis the PTX-3 level was 2.34±0.48 ng/ml (r&lt;0.05). Distribution of PTX-3 had same character, both in patients with DM type 2, and in patients without DM type 2. Conclusions. The diffusive cardiosclerosis was met more often in patients with coronary artery disease and the accompanying diabetes melitus type 2 (in 58.7%). The diagnostic value of pentraxin-3 is to increase the level of pentraxinemia in patients with coronary heart disease with concomitant type 2 diabetes. The pentraxin-3 levels in patients with stable stenocardia were authentically higher, than in patients with diffusive and post-infarct cardiosclerosis that is caused by more distinct activation immune inflammation.
