Abstract
Aim: The potential bond between pentraxin-3 levels and neonatal sepsis has been the center of research in many primary studies. The aim of the current meta-analysis is to examine whether there are differences among pentraxin-3 levels in septic and in healthy neonates.Materials and Methods: Our search strategy included the systematic search of the following databases: MEDLINE, Clinicaltrials.gov, Cochrane Central Register of Controlled Trials (CENTRAL), Google Scholar, using a structured algorithm. Statistical analysis of the overall outcome was done using Revman 5.4 software while leave-one-out and meta-regression analysis were done using the R software. Quality assessment of the included studies was done using the Newcastle-Ottawa scale.Results: Pentraxin-3 levels were found to be higher in newborns affected by sepsis than in healthy neonates with an MD = 7.66 [95% CI 0.89, 14.42 (p = .03, I2 = 99%)]. Subgroup analysis, based on the country of origin of the included study, led to I2 = 0 with an MD = 1.25 with 95% CI [0.82, 1.69], p < 10-5. Publication bias was assessed using the trim and fill method together with visual inspection of the funnel plots, showcasing no missing studies.Conclusion: The results of our study show that pentraxin-3 is elevated in neonates with sepsis making it a potential biomarker that needs to be assessed for its diagnostic accuracy in future cohort studies.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that caused a global outbreak of coronavirus disease 2019 (COVID-19) pandemic. To elucidate the mechanism of SARS-CoV-2 replication and immunogenicity, we performed a comparative transcriptome profile of mRNA and long non-coding RNAs (lncRNAs) in human lung epithelial cells infected with the SARS-CoV-2 wild-type strain (8X) and the variant with a 12-bp deletion in the E gene (F8). In total, 3,966 differentially expressed genes (DEGs) and 110 differentially expressed lncRNA (DE-lncRNA) candidates were identified. Of these, 94 DEGs and 32 DE-lncRNAs were found between samples infected with F8 and 8X. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyzes revealed that pathways such as the TNF signaling pathway and viral protein interaction with cytokine and cytokine receptor were involved. Furthermore, we constructed a lncRNA-protein-coding gene co-expression interaction network. The KEGG analysis of the co-expressed genes showed that these differentially expressed lncRNAs were enriched in pathways related to the immune response, which might explain the different replication and immunogenicity properties of the 8X and F8 strains. These results provide a useful resource for studying the pathogenesis of SARS-CoV-2 variants.

Abstract
Neonatal sepsis is a common cause of neonatal morbidity and mortality. The diagnosis of newborn sepsis is still difficult. Different early objective diagnostic tests or specific signs and symptoms, particularly in preterm infants, make it difficult to diagnose neonatal sepsis. This review article describes biomarkers and their role in the early diagnosis, treatment, and prognosis of neonatal sepsis. It also explores the possible advances and future prospects of these biomarkers. An ideal sepsis biomarker will not only help in the guidance of the use of antibiotics when not needed but also the duration of the course of antibiotics if sepsis is proven. It should also have high sensitivity, specificity, positive predictive value, and negative predictive value. These biomarkers hold a promising position in the management of neonatal sepsis and translate into use in clinical settings. Metabolomics, a diagnostic method based on detecting metabolites found in biological fluids, may open new possibilities in the management of critically ill newborns.

Bronchoalveolar lavage cytokine-based risk stratification of minimal acute rejection in clinically stable lung transplant recipients. J Heart Lung Transplant 2021; 40:1540-1549. [PMID: 34215500 DOI: 10.1016/j.healun.2021.05.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Revised: 05/14/2021] [Accepted: 05/24/2021] [Indexed: 10/21/2022] Open
Abstract
BACKGROUND Acute cellular rejection (ACR) remains the most significant risk factor for chronic lung allograft dysfunction (CLAD). While clinically significant or higher-grade (≥A2) ACR is generally treated with augmented immunosuppression (IS), the management of clinically stable grade A1 ACR remains controversial. At our center, patients with clinically stable grade A1 ACR are routinely not treated with augmented IS. While the overall outcomes in this group of patients at our center are equivalent to patients with stable A0 pathology, CLAD and death rates remain overall high. We hypothesized that a distinct cytokine signature at the time of early minimal rejection state would be associated with worse outcomes. Specifically, we aimed to determine whether bronchoalveolar lavage (BAL) biomarkers at the time of first clinically stable grade A1 ACR (CSA1R) are predictive of subsequent CLAD or death. METHODS Among all adult, bilateral, first lung transplants, performed 2010-2016, transbronchial biopsies obtained within the first-year post-transplant were categorized as clinically stable or unstable based on the presence or absence of ≥10% concurrent drop in forced expiratory volume in 1 second (FEV1). We assessed BAL samples obtained at the time of CSA1R episodes, which were not preceded by another ACR (i.e., first episodes). Twenty-one proteins previously associated with ACR or CLAD were measured in the BAL using a multiplex bead assay. Association between protein levels and subsequent CLAD or death was assessed using Cox Proportional Hazards models, adjusted for relevant peri-transplant clinical covariates. RESULTS We identified 75 patients with first CSA1R occurring at a median time of 98 days (range 48.5-197) post-transplant. Median time from transplant to CLAD or death was 1247 (756.5-1921.5) and 1641 days (1024.5-2326.5), respectively. In multivariable models, levels of MCP1/CCL2, S100A8, IL10, TNF-receptor 1, and pentraxin 3 (PTX3) were associated with both CLAD development and death (p < 0.05 for all). PTX3 remained significantly associated with both CLAD and death after adjusting for multiple comparisons. CONCLUSION Our data indicate that a focused BAL protein signature, with PTX3 having the strongest association, may be useful in determining a subset of CSA1R patients at increased risk and may benefit from a more aggressive management strategy.

Abstract
OBJECTIVE To investigate the behavior of pentraxin-3 (PTX3), troponin T (hsTnT), N-terminal pro-B type Natriuretic Peptide (NT-proBNP) in sepsis and their relationships with sepsis severity and oxygen transport/utilization impairment. DESIGN Retrospective analysis of PTX3, hsTnT, NT-proBNP levels at day 1, 2, and 7 after admission in the intensive care unit in a subset of the Albumin Italian Outcome Sepsis database. SETTING Forty Italian intensive care units. PATIENTS Nine hundred fifty-eight septic patients enrolled in the randomized clinical trial comparing albumin replacement plus crystalloids and crystalloids alone. INTERVENTIONS The patients were divided into sextiles of lactate (marker of severity), ScvO2 (marker of oxygen transport), and fluid balance (marker of therapeutic strategy). MEASUREMENTS AND MAIN RESULTS PTX3 and hsTnT were remarkably similar in the two treatment arms, while NT-proBNP was almost double in the albumin treatment group. However, as the distribution of all these biomarkers was similar between control and treatment arms, for the sake of clarity, we analyzed the patients as a single cohort. PTX3 (71.8 [32.9-186.3] ng/mL), hsTnT (50.4 [21.6-133.6] ng/L), and NT-proBNP (4,393 [1,313-13,837] ng/L) were abnormally elevated in 100%, 84.5%, 93.4% of the 953 patients and all decreased from day 1 to day 7. PTX3 monotonically increased with increasing lactate levels. The hsTnT levels were significantly higher when ScvO2 levels were abnormally low (< 70%), suggesting impaired oxygen transport compared with higher ScvO2 levels, suggesting impaired oxygen utilization. NT-proBNP was higher with higher lactate and fluid balance. At ScvO2 levels < 70%, the NT-proBNP was higher than at higher ScvO2 levels. However, even with higher ScvO2, the NT-proBNP was remarkably elevated, suggesting volume expansion. Increased level of NT-proBNP showed the strongest association with 90-day mortality. CONCLUSIONS The selected biomarkers seem related to different mechanisms during sepsis: PTX3 to sepsis severity, hsTnT to impaired oxygen transport, NT-proBNP to sepsis severity, oxygen transport, and aggressive fluid strategy.

Abstract
BACKGROUND Our previous findings demonstrated that in vitro supplementation of polyphenols, extracted from seeds of red grape (Nero di Troia cultivar), to peripheral lymphomonocytes from patients affected by allergic contact dermatitis (ACD) to nickel (Ni) could reduce the release of proinflammatory cytokines and nitric oxide (NO), while increasing the levels of interleukin (IL)-10, an anti-inflammatory cytokine. OBJECTIVE To assess whether an intervention with oral administration of polyphenols leads to a reduction of peripheral biomarkers in ACD patients. METHODS At T0, 25 patients affected by ACD to Ni were orally administered with 300 mg polyphenols prodie extracted from seeds of red grape (Nero di Troia cultivar) (NATUR-OX®) for 3 months (T1). The other 25 patients affected by ACD to Ni received placebo only for the same period of time. Serum biomarkers were analyzed at T0 and T1. In both groups, seven dropouts were recorded. RESULTS At T1 in comparison to T0, in treated patients, values of interferon-γ, IL-4, IL-17, pentraxin 3 and NO decreased, while IL-10 levels increased when compared with T0 values. Conversely, in placebo- treated patients, no modifications of biomarkers were evaluated at T1. CONCLUSION Present laboratory data rely on the anti-oxidant, anti-inflammatory and anti-allergic properties of polyphenols.

Abstract
Introduction: Change of circulating pentraxin-3 (PTX-3), a novel marker of inflammation, has been observed in women with preeclampsia (PE). However, results of previous studies were inconsistent. We performed a meta-analysis to evaluate the difference of circulating PTX-3 between women with PE and normal pregnancies.Methods: Case-control studies comparing circulating PTX-3 level between women with PE and normal pregnancies were identified via search of PubMed and Embase databases according to a predefined search strategy and inclusion criteria by two independent authors. Meta-analysis was performed with a random-effect model to incorporate heterogeneity.Results: Seventeen studies including 814 women with PE and 949 women with normal pregnancy were included. Results showed that women with PE had significantly higher circulating PTX-3 at diagnosis as compared to women with normal pregnancy (standardized mean difference [SMD]: = 1.74, 95% CI: 1.20-2.29, p < .001; I2 = 94%). The results were consistent regardless of study characteristics including study location, maternal age, sample size, early or late onset of PE, blood sample for PTX-3 measurement, or NOS quality scores. Moreover, higher circulating PTX-3 was also observed before the diagnosis of PE (SMD = 0.65, 95% CI: 0.02-1.29, p = .04; I2 = 87%).Conclusion: Women with PE have higher circulating PTX-3 than women with normal pregnancy. The elevated PTX-3 could be observed before the clinical onset of PE. Future studies are needed to determine whether PTX-3 is an active molecular in the pathogenesis of PE.

Abstract
Aim: An existing meta-analysis have investigated the PTX3 levels in systemic lupus erythematosus (SLE) patients, but the number of studies has increased since 2015. We performed an updated meta-analysis to derive a more accurate estimation. Methods: The related literature was systematically searched in PubMed, Embase and The Cochrane Library database (up to 28 February, 2019). Results: SLE patients had significantly higher PTX3 levels than controls (pooled SMD = 0.48; 95% CI: 0.11-0.84). Subgroup analyses indicated SLE patients from non-Caucasian population, with age ≥45 years, SLE disease activity index (SLEDAI) ≥10 and plasma samples had higher PTX3 levels. Conclusion: Circulating PTX3 levels are increased in SLE patients, and affected by age, ethnicity, SLEDAI and sample type.

Abstract
Calcineurin (CN) inhibitors are effective clinical immunosuppressants but leave patients vulnerable to potentially fatal fungal infections. This study tested the hypothesis that CN inhibition interferes with antifungal immune defenses mediated by monocytes. We showed that NFAT is expressed by human monocytes, and is activated by exposure to fungal ligands. We confirmed that NFAT translocation potently activated target gene transcription using a human monocytic reporter cell line. Inhibition of CN‐NFAT by cyclosporine A significantly reduced monocyte production of TNF‐α, IL‐10, and MCP‐1 proteins in response to pattern recognition receptor ligands as well as to Aspergillus fumigatus conidia. Moreover, we revealed that human monocytes express the antifungal protein pentraxin‐3 under control of NFAT. In conclusion, clinical CN inhibitors have the potential to interfere with the novel NFAT‐dependent pentraxin‐3 pathway as well as antifungal cytokine production in human monocytes, thereby impeding monocyte‐mediated defenses against fungal infection in immune‐suppressed patients.

Abstract
Background Leprosy, the leading infectious cause of disability worldwide, remains a major public health challenge in the most severely affected countries despite the sharp decline in new cases in recent years. The search for biomarkers is essential to achieve a better understanding of the molecular and cellular mechanisms underlying the disease. Methods Pentraxin-3 (PTX3) analyses of sera from 87 leprosy patients with or without reactions were conducted via enzyme-linked immunosorbent assay. In situ identification of PTX3 in skin lesion was confirmed by quantitative reverse-transcription polymerase chain reaction, immunohistochemistry, and immunofluorescence assays. Results We found that PTX3 serum levels were higher in multibacillary patients when evaluated before the onset of acute erythema nodosum leprosum (ENL) and persistently elevated during reaction. Thalidomide treatment reduced PTX3 in the serum 7 days after starting treatment. In situ analyses have also demonstrated enhancement of PTX3 in ENL lesions and showed that treatment with thalidomide reduced its expression and the prominent neutrophilic infiltrate, a hallmark of the disease. Conclusions In summary, our study provides in vivo evidence that PTX3 is enhanced during ENL but not in reversal reaction and provides a new molecular target in ENL pathogenesis.

Abstract
Mesenchymal stromal cells (MSCs) are adult, multipotent cells of mesodermal origin representing the progenitors of all stromal tissues. MSCs possess significant and broad immunomodulatory functions affecting both adaptive and innate immune responses once MSCs are primed by the inflammatory microenvironment. Recently, the role of extracellular vesicles (EVs) in mediating the therapeutic effects of MSCs has been recognized. Nevertheless, the molecular mechanisms responsible for the immunomodulatory properties of MSC-derived EVs (MSC-EVs) are still poorly characterized. Therefore, we carried out a molecular characterization of MSC-EV content by high-throughput approaches. We analyzed miRNA and protein expression profile in cellular and vesicular compartments both in normal and inflammatory conditions. We found several proteins and miRNAs involved in immunological processes, such as MOES, LG3BP, PTX3, and S10A6 proteins, miR-155-5p, and miR-497-5p. Different in silico approaches were also performed to correlate miRNA and protein expression profile and then to evaluate the putative molecules or pathways involved in immunoregulatory properties mediated by MSC-EVs. PI3K-AKT signaling pathway and the regulation of actin cytoskeleton were identified and functionally validated in vitro as key mediators of MSC/B cell communication mediated by MSC-EVs. In conclusion, we identified different molecules and pathways responsible for immunoregulatory properties mediated by MSC-EVs, thus identifying novel therapeutic targets as safer and more useful alternatives to cell or EV-based therapeutic approaches.

Pentraxin 3 deficiency enhances features of chronic rejection in a mouse orthotopic lung transplantation model. Oncotarget 2018; 9:8489-8501. [PMID: 29492210 PMCID: PMC5823599 DOI: 10.18632/oncotarget.23902] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2017] [Accepted: 11/12/2017] [Indexed: 12/24/2022] Open
Abstract
Chronic lung allograft dysfunction (CLAD) is a serious complication after lung transplantation and thought to represent chronic rejection. Increased expression of Pentraxin 3 (PTX3), an acute phase protein, was associated with worse outcome in lung transplant patients. To determine the role of recipient PTX3 in development of chronic rejection, we used a minor alloantigen-mismatched murine orthotopic single lung transplant model. Male C57BL/10 mice were used as donors. Male PTX3 knockout (KO) mice and their wild type (WT) littermates on 129/SvEv/C57BL6/J background were used as recipients. In KO recipients, 7/13 grafted lungs were consolidated without volume recovery on CT scan, while only 2/9 WT mice showed similar graft consolidation. For grafts where lung volume could be reliably analyzed by CT scan, the lung volume recovery was significantly reduced in KO mice compared to WT. Interstitial inflammation, parenchymal fibrosis and bronchiolitis obliterans scores were significantly higher in KO mice. Presence of myofibroblasts and lymphoid aggregation was significantly enhanced in the grafts of PTX3 KO recipients. Recipient PTX3 deficiency enhanced chronic rejection-like lesions by promoting a fibrotic process in the airways and lung parenchyma. The underlying mechanisms and potential protective role of exogenous PTX3 as a therapy should be further explored.
