Abstract
BACKGROUND Kawasaki disease (KD) is a pediatric systemic vasculitis characterized by endothelial cell dysfunction. Semaphorin 7A (Sema7A) has been reported to regulate endothelial phenotypes associated with cardiovascular diseases, while its role in KD remains unknown. This study aims to investigate the effect of Sema7A on endothelial permeability and inflammatory response in KD conditions. METHODS Blood samples were collected from 68 KD patients and 25 healthy children (HC). The levels of Sema7A and A Disintegrin and Metalloprotease 17 (ADAM17) in serum were measured by enzyme-linked immunosorbent assay (ELISA), and Sema7A expression in blood cells was analyzed by flow cytometry. Ex vivo monocytes were used for Sema7A shedding assays. In vitro human coronary artery endothelial cells (HCAECs) were cultured in KD sera and stimulated with Sema7A, and TNF-α, IL-1β, IL-6, and IL-18 of HCAECs were measured by ELISA and qRT-PCR. HCAECs monolayer permeability was measured by FITC-dextran. RESULTS The serum level of Sema7A was significantly higher in KD patients than in HC and correlated with disease severity. Monocytes were identified as one of the source of elevated serum Sema7A, which implicates a process of ADAM17-dependent shedding. Sera from KD patients induced upregulation of plexin C1 and integrin β1 in HCAECs compared to sera from HC. Sema7A mediated the proinflammatory cytokine production of HCAECs in an integrin β1-dependent manner, while both plexin C1 and integrin β1 contributed to Sema7A-induced HCAEC hyperpermeability. CONCLUSIONS Sema7A is involved in the progression of KD vasculitis by promoting endothelial permeability and inflammation through a plexin C1 and integrin β1-dependent pathway. Sema7A may serve as a potential biomarker and therapeutic target in the prognosis and treatment of KD.

Abstract
BACKGROUND To date, no study has investigated the effects of probiotic yogurt as a functional food in patients with chronic heart failure (CHF). Therefore, the aim of this study was to compare the impact of probiotic yogurt versus ordinary yogurt on inflammatory, endothelial, lipid and renal indices in CHF patients. In this randomized, triple-blind clinical trial, 90 patients with CHF were randomly allocated into two groups to take either probiotic or ordinary yogurt for 10 weeks. Serum levels of soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK), soluble cluster of differentiation 163 (sCD163), asymmetric dimethylarginine (ADMA), and lecithin cholesterol acyltransferase (LCAT) were measured by using ELISA kits, and blood urea nitrogen (BUN) was measured by calorimetry method at baseline and at the end of trial. The P-value <0.05 was defined as statistically significant. RESULTS Seventy-eight patients completed the study. At the end of the intervention, the levels of sTWEAK in both groups increased significantly, and this increase was greater in the probiotic yogurt group [691.84 (335.60, 866.95)] compared to control group [581.96 (444.99, 929.40)], and the difference between the groups was statistically significant after adjusting for confounders (P-value: 0.257, adjusted P-value: 0.038). However, no significant differences were found between the groups in the cases of other study indices. CONCLUSION Probiotic yogurt may be useful for improving the inflammatory status in patients with CHF through increasing sTWEAK levels, however, further studies are needed in this area. © 2022 Society of Chemical Industry.

Abstract
OBJECTIVE The proprotein convertase furin is known to be involved in the processing of pro-B-type natriuretic peptide (proBNP) and prorenin receptor (PRR), suggesting that it has a potential function in blood pressure regulation. We investigated the role of furin in the etiology of pre-eclampsia and its related disorder, unexplained fetal growth restriction (FGR) without hypertension. METHODS We evaluated serum and placental furin levels in pre-eclampsia, FGR and uncomplicated pregnancy. Additionally, we investigated the correlation between the serum furin levels and products of furin enzymatic activity or clinical parameters. RESULTS We demonstrated that the maternal circulation in cases of pre-eclampsia and FGR had lower levels of soluble furin than uncomplicated pregnancies. Both NT-proBNP and soluble PRR were elevated in pre-eclampsia, whereas only soluble PRR was at higher levels in unexplained FGR. Linear regression analysis revealed a negative correlation between the serum furin level and that of NT-proBNP or soluble PRR. While we observed that the serum furin or soluble PRR level correlated with blood pressure, a stronger correlation was observed with birth and placental weights. Further to this, the FURIN mRNA levels were significantly reduced in placental pre-eclamptic placentas as well as in FGR cases. CONCLUSION These data suggest the possibility that reduced levels of furin may be the result of a negative feedback from the activation of the renin-angiotensin pathway that leads to feto-placental dysfunction with or without maternal hypertension. This may represent an etiologic pathway of pre-eclampsia and unexplained FGR.

Abstract
Tuberculosis (TB) is a disease instigated by Mycobacterium tuberculosis. Peripheral blood monocytes represent highly efficient effector cells of innate immunity against TB. Little is known about monocyte subsets and their potential involvement in the development of M. tuberculosis drug resistance in patients with TB. This study was conducted to investigate alterations in monocyte subsets, CD163 expression on monocytes, and its serum level in patients without and with rifampicin resistance TB (RR-TB) and healthy controls. A total of 164 patients with TB (84 without RR-TB and 80 patients with RR-TB) and 85 healthy controls were enrolled in this study. The percentages of various monocyte subsets and surface expression of CD163 on monocytes were quantitatively determined using flow cytometry. The serum level of CD163 was determined by commercially available ELISA kits. Decreased frequency of classical monocytes was detected in patients with RR-TB. Non-classical monocytes were decreased in patients without RR-TB; however, intermediate monocytes were raised in patients with RR-TB. The serum level of CD163 was decreased in patients of RR-TB that showsed a positive correlation with the frequency of CD14++CD16-CD163+ and CD14++CD16+CD163+ monocytes. It is concluded that decreased classical monocytes and sCD163 in patients with RR-TB could be an indicator of drug resistance.

Abstract
Magnetic resonance imaging (MRI) is the gold standard for glioblastoma (GBM) patient evaluation. Additional non-invasive diagnostic modalities are needed. GBM is heavily infiltrated with tumor-associated macrophages (TAMs) that can be found in peripheral blood. FKBP51s supports alternative-macrophage polarization. Herein, we assessed FKBP51s expression in circulating monocytes from 14 GBM patients. The M2 monocyte phenotype was investigated by qPCR and flow cytometry using antibodies against PD-L1, CD163, FKBP51s, and CD14. MRI assessed morphologic features of the tumors that were aligned to flow cytometry data. PD-L1 expression on circulating monocytes correlated with MRI tumor necrosis score. A wider expansion in circulating CD163/monocytes was measured. These monocytes resulted in a dramatic decrease in patients with an MRI diagnosis of complete but not partial surgical removal of the tumor. Importantly, in patients with residual tumor, most of the peripheral monocytes that in the preoperative stage were CD163/FKBP51s- had turned into CD163/FKBP51s+. After Stupp therapy, CD163/FKBP51s+ monocytes were almost absent in a case of pseudoprogression, while two patients with stable or true disease progression showed sustained levels in such circulating monocytes. Our work provides preliminary but meaningful and novel results that deserve to be confirmed in a larger patient cohort, in support of potential usefulness in GBM monitoring of CD163/FKBP51s/CD14 immunophenotype in adjunct to MRI.

Abstract
BACKGROUND AND AIMS CD163, a surface hemoglobin-haptoglobin scavenger receptor, is expressed on macrophages and monocytes and up-regulated during macrophage activation. This study aimed to evaluate CD163 in nonalcoholic steatohepatitis patients as a diagnostic and prognostic marker in such patients. METHODS Serum samples were collected from 41 NAFLD patients and 14 healthy controls. All cases were subjected to clinical assessment, abdominal ultrasound examination, laboratory assessment including liver function and enzymes, kidney function, and lipid profile. Fib-4 and NAFLD fibrosis score were calculated for all patients. Also, serum levels of CD163 were detected by ELISA technique. RESULTS The present study showed that BMI, NAFLD fibrosis score (NFS), uric acid, cholesterol, and triglyceride levels were significantly elevated in the NAFLD cases compared with healthy controls (P < 0.05). The serum level of sCD163 was considerably higher in NAFLD cases (9.97 ± 9.97 ng/ml) vs. healthy controls (1.87 ± 0.83 ng/ml) (p < 0.001). Circulating level of sCD163 was significantly higher in the obese-diabetic subjects and diabetic non-obese patients as compared with the lean healthy subjects (11.15 ± 7.69 ng/ml) and 11.46 ± 13.83 ng/ml vs. 1.87 ± 0.83 ng/ml, P < 0.05; respectively. The sensitivity and specificity of this marker was 85.4%, and 92.9 for distinguishing patients with NAFLD in obese and/or diabetic subjects from healthy controls. CONCLUSION serum level of CD163 can be used as a diagnostic marker for individuals with NAFLD. However, it didn't correlate with NAFLD fibrosis score of those patients and thus couldn't predict the severity of disease.

Abstract
BACKGROUND The prevalence of heart failure (HF) is rising with ageing population and constitutes a major health problem globally. A common complication of HF is pulmonary hypertension (PH) which negatively impacts survival. A pathophysiological association between HF and PH with tumorigenic processes has been suggested. We aimed to identify the plasma levels of, and the association between tumour-related proteins and hemodynamic improvements in patients with HF and PH due to left heart disease (LHD) before and 1-year after heart transplantation (HT). METHODS Forty-eight tumour-related proteins were measured with proximity extension assay in plasma from 20 controls and 26 HF patients before and 1-year after HT. Patients' hemodynamics were measured with right heart catheterization. RESULTS Out of 48 proteins, specifically, plasma levels of endocan and brother of CDO (BOC) were elevated in end-stage HF patients compared to controls (p < 0.001), but decreased after HT (p < 0.01), towards controls' levels. The decrease of endocan levels after HT correlated with improved mean pulmonary arterial pressure (rs = 0.80, p < 0.0001), pulmonary arterial wedge pressure (rs = 0.63, p = 0.0012), and pulmonary vascular resistance (rs = 0.70, p < 0.001). The decrease and normalization of BOC after HT correlated with decreased mean right atrial pressure (rs = 0.61 p = 0.0015) and NT-proBNP (rs = 0.57, p = 0.0022), as well as increased cardiac index (rs = - 0.51, p = 0.0086) and left-ventricular stroke work index (rs = - 0.57, p = 0.0039). CONCLUSION Our results suggest that (i) plasma endocan in HF may reflect the state of pulmonary vascular congestion and PH-LHD, whereas (ii) plasma BOC may reflect the cardiac function and the hemodynamic overload in HF. The exact role of these proteins and their clinical applicability as biomarkers in HF and PH-LHD ought to be investigated in larger cohorts.

Abstract
Background: This study assessed the influence of the haptoglobin phenotype on markers regulating inflammation in patients with type 2 diabetes. Methods: The haptoglobin phenotypes, soluble form of CD163 receptor (sCD163), p53 concentrations and high mobility group box protein 1 (HMGB1), interleukin 10 (IL-10) secretion in serum were assayed via ELISA tests. In the first part of the project, patients were divided into three groups which differed by the haptoglobin phenotype, and afterwards into two groups according to the criterion of the presence or absence of cardiovascular disease. Results: Diabetic patients with haptoglobin phenotype 1-1 (Hp1-1) had a significantly higher concentration of IL-10 and sCD163 compared to haptoglobin phenotype 2-1 (Hp2-1) and haptoglobin phenotype 2-2 (Hp2-2). Moreover, diabetic patients with Hp1-1 had a significantly lower concentration of p53 and HMGB1 compared to diabetic patients with Hp2-1 and Hp2-2. The results have shown that diabetics with Hp2-1 had a significantly lower postprandial glucose level compared to diabetics with Hp2-2. Apart from that, there were no differences in the occurrence of haptoglobin variants between patients with or without cardiovascular disease. Conclusions: Our study provides new data for a relationship between the type of haptoglobin in patients with type 2 diabetes and the concentration of factors that regulate the body’s inflammation. We have shown that the Hp1-1 can serve as a genetic marker of inflammatory processes.

Abstract
Ethanol intake increases plasma concentrations of triglycerides and chronic ethanol use impairs lipid metabolism and causes chronic inflammation. The gut plays an important role in metabolic handling of nutrients, including lipids, and a leaky gut associated with alcohol intake, allowing inflammatory signals to the portal vein, has been proposed to constitute a mechanism by which ethanol induces hepatic inflammation. We compared the effects of enteral and parenteral administration of ethanol on a range of circulating inflammation markers (including soluble CD163, a marker of liver macrophage activation), lipids, cholecystokinin (CCK) and fibroblast growth factor 19 (FGF19) as well as gallbladder volume. On two separate and randomized study days, we subjected healthy men (n = 12) to double-blinded intragastric ethanol infusion (IGEI) and isoethanolemic intravenous ethanol infusion (IVEI). Blood was sampled and ultrasonographic evaluation of gallbladder volume was performed at frequent intervals for 4 h after initiation of ethanol administration on both days. Little or no effects were observed on plasma levels of inflammation markers during IGEI and IVEI, respectively. Circulating levels of total, low-density lipoprotein and high-density lipoprotein cholesterol decreased after ethanol administration independently of the administration form. Triglyceride and very low-density lipoprotein (VLDL) cholesterol concentrations increased more after IGEI compared to IVEI. IVEI had no effect on plasma CCK and caused an increased gallbladder volume whereas IGEI elicited a CCK response (P < 0.0001) without affecting gallbladder volume. Circulating FGF19 concentrations decreased equally in response to both ethanol administration forms. In conclusion, by evaluating a range of circulating inflammation markers during IGEI and IVEI we were not able to detect signs of systemic low-grade inflammation originating from the presence of ethanol in the gut. IVEI increased gallbladder volume whereas IGEI increased plasma CCK (with neutral effect on gallbladder volume), increased plasma VLDL cholesterol and triglyceride concentrations; indicating that the enteral route of administration may influence ethanol's effects on lipid metabolism.

Abstract
The macrophage-associated molecule CD163 has been reported as a prognostic biomarker in different cancer types, but its role in colorectal cancer (CRC) is unclear. We studied CD163 in the tumor microenvironment and circulation of patients with CRC in relation to clinicopathological parameters. An enzyme-linked immunosorbent assay (ELISA) was used to measure the serum sCD163 levels and multiparameter flow cytometry was used to study the peripheral blood monocytes and their CD163 expression in CRC patients (N = 78) and healthy donors (N = 50). The distribution of tumor-associated macrophages (TAMs) was studied in primary colorectal tumors with multiplex immunofluorescence. We showed that CRC patients with above-median sCD163 level had a shorter overall survival (OS, p = 0.035) as well as disease-free survival (DFS, p = 0.005). The above-median sCD163 remained significantly associated with a shorter DFS in the multivariate analysis (p = 0.049). Moreover, a shorter OS was observed in CRC patients with an above-median total monocyte percentage (p = 0.007). The number and phenotype of the stromal and intraepithelial TAMs in colorectal tumors were not associated with clinical outcome. In conclusion, sCD163 and monocytes in the circulation may be potential prognostic biomarkers in CRC patients, whereas TAMs in the tumor showed no association with clinical outcome. Thus, our results emphasize the importance of the innate systemic immune response in CRC disease progression.

Abstract
BACKGROUND Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is attracting considerable attention due to disease acceleration and substantial mortality. Macrophages are known to regulate the fibrotic process in idiopathic pulmonary fibrosis. OBJECTIVE We investigated if two new macrophage-specific serum biomarkers, soluble mannose receptor (MR, sCD206) and soluble CD163 (sCD163), increased in serum obtained from patients with AE-IPF compared to stable IPF (S-IPF). METHODS A total of 36 IPF patients with AE status, 54 IPF patients with stable status, and 27 normal controls were enrolled in this study. The levels of serum sCD206 and sCD163 were compared among the three groups and analysed with the clinical features and mortality of IPF. RESULTS The serum concentrations of both markers were higher in patients with AE-IPF than in those with S-IPF (580.0 ng/ml vs 335 ng/ml for sCD206 and 69.2 ng/ml vs 37.9 ng/ml for sCD163). The level of sCD206 was related to an increased risk of mortality (HR = 1.002, p < 0.001). The best separation between decedents and survivors was obtained by sCD206 (area under the receiver operating characteristic curve [AUC] 0.712 and 95% confidence interval 0.595-0.830). CONCLUSION Our data demonstrated that the macrophage-related markers sCD206 and sCD163 were significantly higher in patients with IPF, especially sCD206 in AE-IPF patients. The high level of serum sCD206 was associated with mortality in idiopathic pulmonary fibrosis.

Abstract
The (pro)renin receptor ((P)RR) is cleaved to generate soluble (P)RR (s(P)RR), which reflects the status of the tissue renin-angiotensin system. Hemodialysis (HD) patients have a poor prognosis due to the increased prevalence of cardiovascular diseases. The present study aimed to investigate whether serum s(P)RR level is associated with the worsening of cardiac function in HD patients. A total of 258 maintenance HD patients were recruited and serum s(P)RR concentration was measured. Background factors in patients who survived (S group) and patients who died (D group) during the 12-month follow-up period and relationships between serum s(P)RR level and changes in cardiac function during the follow-up period in the S group were investigated. The median serum s(P)RR value at baseline was 29.8 ng/ml. Twenty-four patients died during the follow-up period. Cardiothoracic ratio, human atrial natriuretic peptide (hANP), brain natriuretic peptide (BNP), and E over e-prime were significantly higher in the D group. In the S group, changes in hANP or BNP were significantly greater in the higher serum s(P)RR group than in the lower serum s(P)RR group. High serum s(P)RR level was significantly correlated with changes in BNP, independent of other factors. High serum s(P)RR level was associated with increases in BNP, independent of other risk factors, suggesting that an increased expression of (P)RR may be associated with a progression of heart failure in HD patients and that serum s(P)RR concentration could be used as a biomarker for selecting patients requiring intensive care.

Abstract
The association between the tumor microenvironment (TME) and treatment response or survival has been a recent focus in several types of cancer. However, most study materials are resected specimens that were completely modified by prior chemotherapy; therefore, the unmodified host immune condition has not yet been clarified. The aim of the present study was to evaluate the relationship between TME assessed in pre-therapeutic biopsy samples and chemoresistance in esophageal cancer (EC). A total of 86 endoscopic biopsy samples from EC patients who received neoadjuvant chemotherapy (NAC) prior to surgery were evaluated for the number of intratumoral CD4+ lymphocytes (with/without Foxp3 expression), CD8+ lymphocytes (with/without PD-1 expression), monocytes (CD14+ ) and macrophages (CD86+ , CD163+ and CD206+ ) by multiplex immunohistochemistry (IHC). The number of tumor-infiltrating CD206+ macrophages I significantly correlated with cT, cM, cStage and neutrophil/lymphocyte ratio (NLR), whereas the number of lymphocytes (including expression of Foxp3 and PD-1) was not associated with clinico-pathological features. The high infiltration of CD163+ or CD206+ macrophages was significantly associated with poor pathological response to NAC (P = 0.0057 and 0.0196, respectively). Expression of arginase-1 in CD163+ macrophages tended to be higher in non-responders (29.4% vs 18.2%, P = 0.17). In addition, patients with high infiltration of M2 macrophages exhibited unfavorable overall survival compared to those without high infiltration of M2 macrophages (5-year overall survival 57.2% vs 71.0%, P = 0.0498). Thus, a comprehensive analysis of TME using multiplex IHC revealed that M2 macrophage infiltration would be useful in predicting the response to NAC and long-term survival in EC patients.

Abstract
OBJECTIVES Elite controllers (ECs), viraemic controllers (VCs), and long-term nonprogressors (LTNPs) control HIV viral replication or maintain CD4 T-cell counts without antiretroviral therapy, but may have increased cardiovascular disease (CVD) risk compared to HIV-uninfected persons. We evaluated subclinical carotid and coronary atherosclerosis and inflammatory biomarker levels among HIV controllers, LTNPs and noncontrollers and HIV-uninfected individuals in the Multicenter AIDS Cohort Study (MACS) and the Women's Interagency HIV Study (WIHS). METHODS We measured carotid plaque presence and common carotid artery intima-media thickness (IMT) in 1729 women and 1308 men, and the presence of coronary artery calcium and plaque in a subgroup of men. Associations between HIV control category and carotid and coronary plaque prevalences were assessed by multivariable regression analyses adjusting for demographics and CVD risk factors. Serum inflammatory biomarker concentrations [soluble CD163 (sCD163), soluble CD14 (sCD14), galectin-3 (Gal-3), galectin-3 binding protein (Gal-3BP) and interleukin (IL)-6] were measured and associations with HIV control category assessed. RESULTS We included 135 HIV controllers (30 ECs) and 135 LTNPs in the study. Carotid plaque prevalence and carotid IMT were similar in HIV controllers, LTNPs and HIV-uninfected individuals. HIV controllers and LTNPs had lower prevalences of carotid plaque compared to viraemic HIV-infected individuals. The prevalence of coronary atherosclerosis was similar in HIV controllers/LTNPs compared to HIV-uninfected and viraemic HIV-infected men. Controllers and LTNPs had higher concentrations of sCD163 and sCD14 compared to HIV-uninfected persons. CONCLUSIONS Subclinical CVD was similar in HIV controllers, LTNPs and HIV-uninfected individuals despite elevated levels of some inflammatory biomarkers. Future studies of HIV controllers and LTNPs are needed to characterize the risk of CVD among HIV-infected persons.

Abstract
CONTEXT Chronic inflammation arising from adipose tissue macrophage (ATM) activation may be central in type 2 diabetes etiology. Our objective was to assess the longitudinal associations of soluble CD163 (sCD163), a novel biomarker of ATM activation, with insulin sensitivity, β-cell function, and dysglycemia in high-risk subjects. METHODS Adults at risk for type 2 diabetes in the Prospective Metabolism and Islet Cell Evaluation (PROMISE) study had 3 assessments over 6 years (n = 408). Levels of sCD163 were measured using fasting serum. Insulin sensitivity was assessed by HOMA2-%S and the Matsuda index (ISI). β-cell function was determined by insulinogenic index (IGI) over HOMA-IR and insulin secretion-sensitivity index-2 (ISSI-2). Incident dysglycemia was defined as the onset of impaired fasting glucose, impaired glucose tolerance, or type 2 diabetes. Generalized estimating equations (GEE) evaluated longitudinal associations of sCD163 with insulin sensitivity, β-cell function, and incident dysglycemia adjusting for demographic and lifestyle covariates. Areas under receiver-operating-characteristic curve (AROC) tested whether sCD163 improved dysglycemia prediction in a clinical model. RESULTS Longitudinal analyses showed significant inverse associations between sCD163 and insulin sensitivity (% difference per standard deviation increase of sCD163 for HOMA2-%S (β = -7.01; 95% CI, -12.26 to -1.44) and ISI (β = -7.60; 95% CI, -11.09 to -3.97) and β-cell function (ISSI-2 (β = -4.67; 95 %CI, -8.59 to -0.58) and IGI/HOMA-IR (β = -8.75; 95% CI, -15.42 to -1.56)). Increased sCD163 was associated with greater risk for incident dysglycemia (odds ratio = 1.04; 95% CI, 1.02-1.06; P < 0.001). Adding sCD163 data to a model with clinical variables improved prediction of incident dysglycemia (AROC=0.6731 vs 0.638; P < 0.05). CONCLUSIONS sCD163 was longitudinally associated with core disorders that precede the onset of type 2 diabetes.

Abstract
Conventional dendritic cells (cDCs) cannot be infected by porcine reproductive and respiratory syndrome virus (PRRSV) but respond to infection via cytokine production, indicating a possible role in initiation/regulation of the immune response against PRRSV. In this work, we evaluated the responses of splenic and blood cDCs, with DEC205+CADM1+CD172a+/− phenotype, as well as those of CD163+ cells against PRRSV and porcine epidemic diarrhea virus (PEDV). Both populations were incubated in the presence of PRRSV or PEDV with and without naïve CD3+ T cells, and cytokine responses were evaluated by qPCR and ELISA. Our results showed that cDCs, but not CD163+ cells, produced IL-12 in response to PRRSV. PEDV did not induce IL-12 production. Cocultures of cDCs and autologous naïve CD3+ cells resulted in decreased IL-12 production and low expression of IFN-γ transcripts in response to PRRSV. Interestingly, cDCs increased the proliferation of naïve T cells in the presence of PRRSV compared with that achieved with monocytes and peripheral blood mononuclear cells (PBMCs). Cocultures of CD163+ cells induced IL-10 and IL-4 expression in the presence of PRRSV and PEDV, respectively. In conclusion, cDCs can selectively produce IL-12 in response to PRRSV but poorly participate in the activation of naïve T cells.

Abstract
INTRODUCTION Idiopathic pulmonary fibrosis (IPF) is a lethal disease with an unclear pathogenic mechanism. Components of the renin-angiotensin system (RAS) have a role in the pathogenesis of IPF, specifically, the aspartyl protease renin acts as a profibrotic factor in the lung. However, the concentration of the RAS components renin and soluble (pro)renin receptor (sPRR) have not been previously evaluated neither in serum nor in bronchoalveolar lavage fluid (BAL) of patients with IPF or chronic Hypersensitivity pneumonitis (cHP), a disease which may be confused with IPF. METHODS The serum levels of renin [IPF patients (n = 70), cHP patients (n = 83), and controls (n = 26)] and sPRR [IPF (n = 28), cHP (37), and controls (n = 20)] were measured by ELISA. Renin was also quantified in BALs of IPF patients and controls by Western blot. RESULTS We found that the levels of renin were higher in serum samples from IPF patients when compared with cHP patients and controls. Furthermore, BALs from IPF patients had more renin than BALs from controls. Unlike renin, the serum levels of sPRR were lower in IPF and cHP patients than in control individuals. CONCLUSIONS The high levels of renin in sera and BALs of IPF patients suggest that renin might play a major role in the pathogenesis of IPF. Results from BAL confirm that renin is produced locally in the lung. Serum levels of renin could be used to differentiate IPF from cHP.

Abstract
BACKGROUND Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is a syndrome with a high short-term mortality rate, and it is crucial to identify those patients at a high mortality risk clinically.
AIM To investigate the clinical value of soluble mannose receptor (sMR) in predicting the 90-day mortality of HBV-ACLF patients.
METHODS A total of 43 patients were diagnosed with HBV-ACLF between October 2017 and October 2018 at the Second Hospital of Anhui Medical University, and all of them were enrolled in this retrospective study. Their serum sMR levels were determined using an enzyme-linked immunosorbent assay. Demographic and clinical data, including gender, age, albumin level, total bilirubin (TBIL) level, international normalized ratio, HBV-DNA level, HBV serological markers, procalcitonin level, interleukin-6 level, and model for end-stage liver disease (MELD) score were accessed at the time of diagnosis of HBV-ACLF. A multivariate logistic regression analysis was used to analyze the independent risk factors for mortality.
RESULTS Serum sMR level was significantly increased in HBV-ACLF patients compared with chronic hepatitis B patients and healthy controls (P < 0.01). When compared with surviving patients, it was higher in those patients who succumbed to HBV-ACLF (P < 0.05). Serum sMR level was positively correlated with MELD score (rs = 0.533, P = 0.001), HBV-DNA level (rs = 0.497, P = 0.022), and TBIL level (rs = 0.894, P < 0.001). Serum sMR level (odds ratio = 1.007, 95% confidence interval: 1.004–1.012, P = 0.001) was an independent risk factor for the 90-day mortality in the HBV-ACLF cases. The patients with HBV-ACLF were stratified into two groups in accordance with their serum sMR levels at the baseline (low risk: < 99.84 pg/mL and high risk: ≥ 99.84 pg/mL). The 90-day mortality rates were 27.3% in the low-risk group and 87.5% in the high-risk group. Furthermore, sMR level apparently improved the performance of MELD score for predicting the prognosis of patients with HBV-ACLF.
CONCLUSION Serum sMR level may be a predictor of the prognosis of HBV-ACLF patients.

Abstract
This study aims to evaluate the clinical value of haptoglobin (Hp) and sCD163 testing for the differential diagnosis of pleural effusion, and investigate the correlation of Hp and sCD163 with the inflammatory response of the body.Pleural effusion samples were collected from 78 patients (38 tuberculous pleural effusions [TPE] and 40 malignant pleural effusions [MPE]). The concentrations of Hp and sCD163 in the pleural effusion were measured by enzyme-linked immunosorbent assay (ELISA).The concentrations of Hp and sCD163 were significantly higher in the TPE group than in the MPE group (P < .05). The sensitivity and specificity of the Hp test for the differential diagnosis of TPE and MPE was 82.4% and 86.1%, respectively (P < .01), while the cut off value was 779.05 ug/mL. Furthermore, the sensitivity and specificity of the sCD163 test for the differential diagnosis of TPE and MPE was 76.3% and 85.0%, respectively (P < .01), while the cut off value was 16,401.11 ng/mL. Moreover, the sensitivity and specificity of the combination of Hp and sCD163 tests for diagnosing TPE was 90.0% and 87.5%, respectively. Hp and IL-1β, TNF-α, CRP and ESR were positively correlated in both the TPE group and MPE group (P < .05). Hp and sCD163 were positively correlated in the TPE group (r = 0.3735, P = .0209), but not in the MPE group (r = 0.22, P = .1684). However, there was no correlation between sCD163 and TNF-α, CRP and ESR in either the TPE group, or the MPE group (P > .05). Furthermore, sCD163 and IL-1β were weakly correlated in the TPE group (r = 0.49, P = .0018), but these had no correlation in the MPE group (r = 0.068, P = .6767).Hp and sCD163 can be used as biological markers for the differential diagnosis of pleural effusion in clinic, and the level of Hp in pleural effusion may reflect the intensity of inflammation in the body to some extent.

Abstract
Plasmodium vivax invasion of human erythrocytes depends on the Duffy Binding Protein (PvDBP) which interacts with the Duffy antigen. PvDBP copy number has been recently shown to vary between P. vivax isolates in Sub-Saharan Africa. However, the extent of PvDBP copy number variation, the type of PvDBP multiplications, as well as its significance across broad samples are still unclear. We determined the prevalence and type of PvDBP duplications, as well as PvDBP copy number variation among 178 Ethiopian P. vivax isolates using a PCR-based diagnostic method, a novel quantitative real-time PCR assay and whole genome sequencing. For the 145 symptomatic samples, PvDBP duplications were detected in 95 isolates, of which 81 had the Cambodian and 14 Malagasy-type PvDBP duplications. PvDBP varied from 1 to >4 copies. Isolates with multiple PvDBP copies were found to be higher in symptomatic than asymptomatic infections. For the 33 asymptomatic samples, PvDBP was detected with two copies in two of the isolates, and both were the Cambodian-type PvDBP duplication. PvDBP copy number in Duffy-negative heterozygotes was not significantly different from that in Duffy-positives, providing no support for the hypothesis that increased copy number is a specific association with Duffy-negativity, although the number of Duffy-negatives was small and further sampling is required to test this association thoroughly. Plasmodium vivax invasion of human erythrocytes relies on interaction between the Duffy antigen and P. vivax Duffy Binding Protein (PvDBP). Whole genome sequences from P. vivax field isolates in Madagascar identified a duplication of the PvDBP gene and PvDBP duplication has also been detected in non-African P. vivax-endemic countries. Two types of PvDBP duplications have been reported, termed Cambodian and Malagasy-type duplications. Our study used a combination of PCR-based diagnostic method, a novel quantitative real-time PCR assay, and whole genome sequencing to determine the prevalence and type of PvDBP duplications, as well as PvDBP copy number on a broad number of P. vivax samples in Ethiopia. We found that over 65% of P. vivax isolated from the symptomatic infections were detected with PvDBP duplications and PvDBP varied from 1 to >4 copies. The majority of PvDBP duplications belongs to the Cambodian-type while the Malagasy-type duplications was also detected. For the asymptomatic infections, despite a small sample size, the majority of P. vivax were detected with a single-copy based on both PCR and qPCR assays. There was no significant difference in PvDBP copy number between Duffy-null heterozygote and Duffy-positive homozygote/heterozygote. Further investigation is needed with expanded Duffy-null homozygotes to examine the functional significance of PvDBP expansion.

Abstract
CD200 is an immunoglobulin superfamily membrane protein that binds to a myeloid cell-specific receptor and induces inhibitory signaling. The aim of this study was to investigate the role of CD200 and its receptor (CD200R1) on kidney transplant (KTx) outcome. In a collective of 125 kidney recipients (University hospital, Heidelberg, Germany), CD200 and CD200R1 concentrations were evaluated immediately before transplantation. Recipient baseline and clinical characteristics and KTx outcome, including acute rejection (AR), acute tubular necrosis, delayed graft function, cytomegalovirus (CMV) and human polyomaviridae (BK) virus infections, and graft loss were evaluated during the first post-transplant year. The association of CD200 and CD200R1 concentrations and CD200R1/CD200 ratios with the outcome of KTx was investigated for the first time in a clinical setting in a prospective cohort. There was a positive association between pre-transplant CD200R1 concentrations and CMV (re)activation (P = .041). Also, increased CD200R1 concentration was associated with a longer duration of CMV infection (P = .049). Both the frequency of AR and levels of creatinine (3 and 6 months after KTx) were significantly higher in patients with an increased CD200R1/CD200 ratio (median: 126 vs 78, P = .008). Increased pre-transplant CD200R1/CD200 ratios predict immunocompetence and risk of AR, whereas high CD200R1 concentrations predict immunosuppression and high risk of severe CMV (re)activation after KTx.

Abstract
Ebola virus disease (EVD) is associated with elevated cytokine levels, and hypercytokinemia is more pronounced in fatal cases. This type of hyperinflammatory state is reminiscent of 2 rheumatologic disorders known as macrophage activation syndrome and hemophagocytic lymphohistiocytosis, which are characterized by macrophage and T-cell activation. An evaluation of 2 cohorts of patients with EVD revealed that a marker of macrophage activation (sCD163) but not T-cell activation (sCD25) was associated with severe and fatal EVD. Furthermore, substantial immunoreactivity of host tissues to a CD163-specific antibody, predominantly in areas of extensive immunostaining for Ebola virus antigens, was observed in fatal cases. These data suggest that host macrophage activation contributes to EVD pathogenesis and that directed antiinflammatory therapies could be beneficial in the treatment of EVD.

Abstract
INTRODUCTION Over the past decades, the number of people with type 2 diabetes (T2D) has increased globally. One of the major complications in these patients is cardiovascular disease; it seems that the cell proliferation inhibition can improve vascular function in these patients. It is proposed that peroxisome proliferator-activated receptor alpha (PPARα) can induce cell cycle arrest via cyclin-dependent kinase inhibitor 2A (p16) activation. Also, it has been shown that phosphorylated tumour suppressor protein p53 is involved in cell senescence by cyclin-dependent kinase inhibitor 1 (p21) upregulation. Resveratrol is a natural polyphenol and appears to improve the vascular function through the mentioned pathways. We will aim to evaluate the effects of resveratrol supplementation on mRNA expression of PPARα, p53, p21 and p16 in patients with T2D. We will also measure serum levels of cluster of differentiation 163 (CD163) and tumour necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) as the indicators of cardiovascular status. METHODS AND ANALYSIS Seventy-two subjects suffering from T2D will participate in this double-blind randomised parallel placebo-controlled clinical trial. Participants will be randomly assigned to receive 1000 mg/day trans-resveratrol or placebo (methyl cellulose) for 8 weeks. The mRNA expression levels of PPARα, p53, p21 and p16 genes will be assessed using real-time PCR and serum CD163 and TWEAK levels will be measured using commercially available ELISA kits at baseline and the end of the study. Clinical outcome parameters (glycaemic and lipid profiles and body composition) will also be measured before and after study duration. ETHICS AND DISSEMINATION The study is performed in agreement with the Declaration of Helsinki and is approved by the Ethics Committee of the Shahid Sadoughi University of Medical Sciences (no: ir.ssu.sph.rec.1396.120). The results will be published in scientific journals. TRIAL REGISTRATION NUMBER IRCT20171118037528N1; Pre-results.

Abstract
Gestational diabetes mellitus (GDM) is today universally diagnosed during late pregnancy. Treating hyperglycaemia during pregnancy reduces the risk of complications, the effect of interventions is however limited due to the late diagnosis. It is thus important to identify biomarkers reaching a high precision for GDM development in early pregnancy. Here we aim to investigate soluble CD163 (sCD163) and soluble tumour necrosis factor-like weak inducer of apoptosis (sTWEAK) in early pregnancy GDM and their association to the development of later glucose intolerance. In this case-control study, women diagnosed with GDM in early pregnancy (n = 70) at Lund University Hospital, Lund, Sweden in 2011-2015 were age- and BMI matched to pregnant volunteers without diabetes (n = 70) recruited in early pregnancy from maternal health care centres in 2014-2015. Plasma levels of sCD163 and sTWEAK were analysed using commercial ELISA. Plasma levels of sCD163 did not differ between patients with and without GDM in early pregnancy (p = 0.86), plasma levels of sTWEAK however was decreased in women with GDM (0.71 [0.4-1.75] ng/ml) compared to controls (1.38 [0.63-4.86] ng/ml; p = 0.003). Women with sTWEAK levels in the lowest tertile had an increased risk of GDM in early pregnancy (p = 0.014). Neither sCD163 nor sTWEAK were associated with later glucose intolerance in women with GDM. This study reports decreased levels of sTWEAK in women with early pregnancy GDM, independent of age and BMI. Neither sCD163 nor sTWEAK were found to be associated to later glucose intolerance.

Abstract
The cellular marker CD163 is a type 1 transmembrane scavenger protein found either on the surface of antigen-presenting cells or in a soluble form (sCD163), released in response to inflammation. Despite an obligatory role in porcine reproductive and respiratory virus (PRRSV) infection, information on sCD163 as a biomarker of disease outcome in swine remains limited. In the present study, we developed a sandwich ELISA using an anti-bovine CD163 antibody, LND68A, in conjunction with the porcine specific 2A10/11 antibody. The ELISA demonstrated that CD163 shedding from porcine alveolar macrophages increased following in vitro exposure to lipopolysaccharide or PRRSV-2 strain NVSL 97-7895. Evaluation of serum sCD163 in healthy feeder pigs identified a significant age effect with concentration rising after birth to a peak at day 19 (P < 0.05) followed by a sharp decline to a minimal level of detection at 9 weeks of age (P < 0.05). Healthy sows showed substantial variation but no significant change in average concentration between early and late lactation. The serum concentration of sCD163 from pigs with homozygous gene edits disrupting translation of the CD163 protein was below the threshold of detection. However, when reformatted as a competitive ELISA the assay identified an interfering substance consistent with the release of a truncated form of the CD163 protein in sera from gene edited animals. With sCD163 shown to be both dynamic and responsive, the described ELISA represents a novel tool for investigation of this molecule as a potential biomarker of disease response in the pig.

Abstract
OBJECTIVE Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is of concern because of its propensity for rapid deterioration and high mortality. Its aetiology and mechanism are still unclear. The aims of this study were to clarify the pathophysiology differences between AE-IPF and stable IPF (S-IPF) by comparing the serum levels of various cytokines and chemokines in the two groups and to identify those involvement in the occurrence of acute exacerbation and associated with mortality. METHODS The study included 28 patients with AE-IPF, 32 patients with S-IPF, and 18 healthy control subjects. We measured the serum cytokine and chemokine levels in all cases by multiplex assay. Serum levels of cytokines and chemokines were compared between AE-IPF and S-IPF subjects. Logistic regression analysis was applied to identify the ability of these variables to predict acute exacerbation. Kaplan-Meier curves were used to analyse survival and Cox proportional hazard regression was used to identify predictors of survival. RESULTS Levels of several cytokines and chemokines were significantly higher in both patient groups with IPF (with the exception of interleukin-2 [IL-2], chemokine cc-motif ligand 3, and RANTES [regulation upon activation normal T-cell express sequence]) than in healthy controls. Serum IL-1β (p = 0.008) and interferon (IFN)-γ (p = 0.007) levels tended to be higher in patients with AE-IPF than in those with S-IPF. The concentration of chemokine cc-motif ligand (CCL) 2 was significantly higher in bronchoalveolar lavage fluid than in serum (p = 0.001). Higher C-reactive protein, lactate dehydrogenase, percent forced vital capacity, percent diffusing capacity of the lung for carbon monoxide, and IFN-γ values in the patients with IPF were correlated with acute exacerbation status, with respective odds ratios of 1.241 (p = 0.011), 1.050 (p = 0.004), 1.043 (p = 0.001), 0.927 (p = 0.014), and 0.929 (p = 0.020). Acute exacerbation status was associated with an increased risk of mortality (hazard ratio 0.107, 95% confidence interval 0.036-0.314; p < 0.001). Univariate Cox regression demonstrated an association of IFN-γ, CCL2, C-X-C motif chemokine 10 (CXCL10) and sCD163 levels with an increased mortality risk (p = 0.015, p = 0.002, p = 0.001, and p = 0.030, respectively). CONCLUSIONS Our data demonstrate that serum levels of some pro-inflammatory cytokines and macrophage chemokines are upregulated during acute exacerbations of IPF and that these exacerbations are associated with the serum IFN-γ level. Chemokines and protein such as sCD163, CCL2, and CXCL10 are associated with activation of macrophages and may have a serious impact on overall survival in patients with IPF.

Abstract
AIMS The risk of gestational diabetes mellitus (GDM) is increased in overweight and obese women potentially involving secreted mediators from adipose tissue. Our main aim was to evaluate if circulating adipokines and monocyte/macrophage markers were dysregulated in GDM and the influence body mass and indices of glucose metabolism had on this association. We further explored if early detection of these markers improved prediction of GDM and if they remained modified during long-term follow-up. MATERIALS AND METHODS Population-based prospective cohort study in 273 pregnant women with markers measured four times during pregnancy and at 5-year follow-up. RESULTS sCD163 was higher (25% at 14-16 weeks, P < 0.001) and adiponectin lower (-17% at 14-16 weeks, P < 0.01) early in pregnancy and at 5-year follow-up in GDM women, independent of BMI, and other GDM risk factors. Leptin, adiponectin, and chemerin were robustly associated with glucose metabolism throughout pregnancy while sCD163 was inversely associated with β-cell function early in pregnancy in women with increased BMI. Finally, the markers at 14 to 16 weeks displayed modest discriminatory properties with regard to prediction of GDM (AUC < 0.7). Using a combination of fasting glucose and sCD163, 53% of GDM could be identified when 25% of the population scored positive suggesting some merit in a multimarker approach. CONCLUSIONS sCD163 and adiponectin were dysregulated in GDM, independent of body mass. None of the adipokines or monocyte/macrophage activation markers displayed clinically useful properties alone for early detection of GDM. Activation of monocytes/macrophages may be an important event in the early development of GDM.

Abstract
Deletion of the prorenin receptor (PRR) in adipose tissue elevates systolic blood pressure (SBP) and the circulating soluble form of PRR (sPRR) in male mice fed a high-fat (HF) diet. However, sex differences in the contribution of adipose-PRR and sPRR to the regulation of the renin-angiotensin system (RAS) in key organs for blood pressure control are undefined. Therefore, we assessed blood pressure and the systemic and intrarenal RAS status in adipose-PRR knockout (KO) female mice. Blockade of RAS with losartan blunted SBP elevation in HF diet-fed adipose-PRR KO mice. ANG II levels were significantly increased in the renal cortex of HF diet-fed adipose-PRR KO female mice, but not systemically. HF diet-fed adipose-PRR KO mice exhibited higher vasopressin levels, water retention, and lower urine output than wild-type (WT) mice. The results also showed that deletion of adipose-PRR increased circulating sPRR and total hepatic sPRR contents, suggesting the liver as a major source of elevated plasma sPRR in adipose-PRR KO mice. To mimic the elevation of circulating sPRR and define the direct contribution of systemic sPRR to the regulation of the RAS and vasopressin, C57BL/6 female mice fed a standard diet were infused with recombinant sPRR. sPRR infusion increased plasma renin levels, renal and hepatic angiotensinogen expression, and vasopressin. Together, these results demonstrate that the deletion of adipose-PRR induced an elevation of SBP likely mediated by an intrarenal ANG II-dependent mechanism and that sPRR participates in RAS regulation and body fluid homeostasis via its capacity to activate the RAS and increase vasopressin levels. NEW & NOTEWORTHY The elevation of systolic blood pressure appears to be primarily mediated by cortical ANG II in high-fat diet-fed adipose-prorenin receptor knockout female mice. In addition, our data support a role for soluble prorenin receptor in renin-angiotensin system activation and vasopressin regulation.

Abstract
Fucoidans are sulfated fucose-based polysaccharides that activate platelets and have pro- and anticoagulant effects; thus, they may have therapeutic value. In the present study, we show that 2 synthetic sulfated α-l-fucoside-pendant glycopolymers (with average monomeric units of 13 and 329) and natural fucoidans activate human platelets through a Src- and phosphatidylinositol 3-kinase (PI3K)-dependent and Syk-independent signaling cascade downstream of the platelet endothelial aggregation receptor 1 (PEAR1). Synthetic glycopolymers and natural fucoidan stimulate marked phosphorylation of PEAR1 and Akt, but not Syk. Platelet aggregation and Akt phosphorylation induced by natural fucoidan and synthetic glycopolymers are blocked by a monoclonal antibody to PEAR1. Direct binding of sulfated glycopolymers to epidermal like growth factor (EGF)-like repeat 13 of PEAR1 was shown by avidity-based extracellular protein interaction screen technology. In contrast, synthetic glycopolymers and natural fucoidans activate mouse platelets through a Src- and Syk-dependent pathway regulated by C-type lectin-like receptor 2 (CLEC-2) with only a minor role for PEAR1. Mouse platelets lacking the extracellular domain of GPIbα and human platelets treated with GPIbα-blocking antibodies display a reduced aggregation response to synthetic glycopolymers. We found that synthetic sulfated glycopolymers bind directly to GPIbα, substantiating that GPIbα facilitates the interaction of synthetic glycopolymers with CLEC-2 or PEAR1. Our results establish PEAR1 as the major signaling receptor for natural fucose-based polysaccharides and synthetic glycopolymers in human, but not in mouse, platelets. Sulfated α-l-fucoside-pendant glycopolymers are unique tools for further investigation of the physiological role of PEAR1 in platelets and beyond.

Soluble (pro)renin receptor [s(P)RR], which is generated from cleavage of (P)RR, can be detected in plasma and urine. s(P)RR levels can reflect the severity of some diseases, such as renal lesions, gestational diabetes mellitus or hypertension, and obstructive sleep apnea syndrome. However, the relationship between s(P)RR levels and the severity of chronic heart failure remains undetermined. We studied s(P)RR levels in 118 patients with chronic heart failure with reduced ejection fraction (HFrEF), including 86 without renal dysfunction (HF) and 32 with renal dysfunction (HF + RF), and 28 healthy subjects (HS) to reveal the relationship between s(P)RR levels and other HFrEF parameters. Plasma s(P)RR levels were 22.2 ± 4.1 ng/mL (HS), 26.4 ± 5.3 ng/ mL (HF) and 30.0 ± 5.3 ng/mL (HF + RF). Plasma s(P)RR levels were significantly higher in the HF group than in the HS group (P < 0.001) and even more increased in the HF + RF group (P < 0.001 vs. the HS group and P < 0.05 vs. the HF group). Multivariate regression analysis revealed that the left ventricular mass index (LVMI) and estimated glomerular filtration rate (eGFR) were independently related to s(P)RR levels in HFrEF patients. In conclusion, high plasma s(P)RR levels are associated with left ventricular remodeling and, especially, with renal dysfunction. Therefore, s(P)RR is a promising evaluative indicator for the severity of HFrEF patients.

Abstract
BACKGROUND AND AIMS Macrophages play a significant role in chronic liver disease as reflected by elevated soluble (s)CD163 and mannose receptor (sMR) levels and associated with liver disease severity and prognosis. Extracellular matrix remodelling associated with fibrogenesis may be affected by systemic inflammation induced by bacterial translocation. Therefore, we aimed to investigate the effect of rifaximin-α, an antibiotic with effect on gut bacteria, on sCD163, sMR, and collagen metabolites. METHODS Fifty-four clinically stable patients with decompensated cirrhosis were randomized to 4 weeks treatment with rifaximin-α (n = 36) or placebo (n = 18). Macrophage markers sCD163, sMR and markers of collagen fibrogenesis (C3M and C4M) and formation (PRO-C3 and P4NPS7) were analysed in plasma before and after treatment. RESULTS sCD163 and sMR levels were associated with liver disease severity (MELD score, sCD163 rho = 0.47, p<0.001 and sMR rho = 0.37, p = 0.005). There was no effect of Rifaximin-α on sCD163 levels (median (range) sCD163 5.64(2.02 to 10.8) at baseline versus 4.42(1.98 to 8.92) at follow-up in the rifaximin-α group and 4.85 (2.29 to 12.1) at baseline versus 4.32 (1.98 to 12.4) at follow-up in the placebo-group), p = 0.34); nor sMR levels, p = 0.34. Also in patients with elevated lipopolysaccharide binding protein (> 5.9 μg/ml, 38 patients) there was no effect of rifaximin-α on sCD163 (p = 0.49) or sMR levels (p = 0.32). CONCLUSION We confirmed that macrophage activation markers sCD163 and sMR are directly associated to liver disease severity (MELD score). However, rifaximin-α has no effect on sCD163, sMR or collagen markers in decompensated cirrhosis and does therefore not seem to interfere with macrophage activation or fibrogenesis.

Abstract
OBJECTIVE To investigate serum levels and mRNA expressions of tumor necrosis factor-like weak inducer of apoptosis (TWEAK) and its receptor CD163 from the patients with psoriasis vulgaris (PV). METHODS Peripheral blood samples were obtained from 28 patients with PV and 15 healthy control subjects. Serum levels of TWEAK and CD163 were detected by ELISA, mRNA expressions of TWEAK and CD163 in peripheral blood were analyzed by real time-PCR, and protein expressions of TWEAK and CD163 were determined by flow cytometry. RESULTS All the 28 PV patients were in progressive stage at the beginning of this study, 10 patients then recovered in convalescent stage after treatment. Compared to healthy controls, PV patients had higher serum TWEAK levels and lower serum CD163 levels. Serum TWEAK level in progressive stage was significantly higher than that in convalescent stage. Serum CD163 level were elevated significantly in convalescent stage compared with those in progressive stage. TWEAK mRNA expression in PV patients were significantly lower than that in healthy controls, but there was no significant differences of CD163 mRNA expression. TWEAK expression in monocytes in progressive stage and convalescent stage were significantly higher than that of controls, CD163 expression in monocytes in progressive stage and convalescent stage significantly lower than that in controls. No correlations wene found between psoriasis area and severity index (PASI) score and expression of TWEAK and CD163. CONCLUSION TWEAK/CD163 pathway may play a role in PV.

Abstract
BACKGROUND AND AIMS Measles is an infectious disease that represents a serious public health problem worldwide, being associated with increased susceptibility to secondary infections, especially in the respiratory and gastrointestinal tracts. The aim of this study was to evaluate sCD163 and sCD14 levels in measles virus (MV) infected patients, as markers of immune activation, in order to better understand their role in the pathogenesis of the disease. TNF-α plasma levels were also evaluated. METHODS sCD163, sCD14 and TNF-α were measured by ELISA in plasma samples of 27 MV infected patients and 27 healthy donors (HD) included as controls. RESULTS At the time of hospital admission, sCD163 and sCD14 levels were significantly higher in MV infected patients than in HD, while a decrease in TNF-α levels were found even if without statistical significance. sCD163 and sCD14 levels were significantly decreased after two months from acute infection compared to hospital admission although they remained significantly higher compared to HD. TNF-α levels increased significantly during the follow-up period. Considering clinical parameters, sCD163 levels positively correlated with aspartate aminotransferase, white blood cell count and neutrophils rate, while negatively correlated with the lymphocyte percentage. sCD14 levels positively correlated with the neutrophil and lymphocyte percentages. CONCLUSIONS These results indicate that, despite the resolution of symptoms, an important macrophage/monocyte activation persists in measles patients, even after two months from infection.

Abstract
BACKGROUND HIV-infected children with long-term nonprogressive (LTNP) disease eventually convert to a progressive disease type, yet the extent to which these children experience the cognitive and emotional symptoms observed in typical progressive HIV (Progressors) is unknown. METHODS Eighty-eight LTNPs, 53 Progressors, and 323 healthy controls completed annual assessments of cognitive and emotional health as part of a prospective study. The 2 HIV-infected groups and the healthy controls were matched on age and sex distribution at enrollment. Plasma HIV RNA, T-cell counts/percentages, activated monocytes, perivascular monocytes, and markers of macrophage activation (sCD163 and sCD14) were compared by progression subtype. Cognitive and emotional outcomes were compared using cross-sectional linear regression analysis and longitudinal sensitivity models. RESULTS LTNPs exhibited the same cognitive phenotype and emotional dysregulation as Progressors, with worse outcomes in both groups compared with controls. In addition, cognitive and emotional symptoms were evident before children reached the minimum age for LTNP designation (8 years). Baseline plasma HIV RNA, sCD163, activated monocytes, and perivascular monocytes were lower in LTNPs versus Progressors, with no difference in T-cell counts/percentages or sCD14 levels. Most LTNPs converted to a progressive disease subtype during the study, with similar cognitive and emotion profiles between these subgroups. CONCLUSIONS Pediatric LTNPs experience cognitive and emotional difficulties that mirror symptoms of progressive disease. The abnormalities are present at young ages and persist independent of plasma T-cell counts. The findings highlight the neurodevelopmental risk of pediatric HIV, even in those with early innate disease control.

Abstract
Aim The influence of sample handling on soluble urokinase plasminogen activator receptor (suPAR) concentrations in serum and EDTA plasma was studied in 16 healthy premenopausal women. Method Blood was collected in dry tubes and tubes containing EDTA and kept at 4°C or 20°C for 1, 3, 8, 24 or 72 hours before processing into serum or EDTA plasma. In addition, serum and EDTA plasma were frozen and thawed 1–8 times. All suPAR measurements were performed by ELISA. Results No significant differences were found between serum or EDTA plasma suPAR concentrations when whole blood samples were kept for 1, 3, 8 or 24 hours. Significantly higher suPAR levels were found in samples kept for 72 hours at 20°C compared to samples processed into serum or EDTA plasma after short-term storage for no more than 24 hours after collection. No significant differences were observed when whole blood was kept at 4°C for up to 72 hours. Repeated freezing and thawing had no significant effect on the serum and EDTA plasma suPAR levels. Conclusion suPAR values in blood samples are dependent on the handling procedures of the samples. All samples of whole blood must be processed into EDTA plasma or serum within 24 hours if kept at 20°C and within 72 hours if kept at 4°C. However, repeated freezing/thawing cycles had no influence on suPAR values in the samples.

Abstract
Vitamin D deficiency is common in patients with chronic obstructive pulmonary disease (COPD), yet a comprehensive analysis of environmental and genetic determinants of serum 25-hydroxyvitamin D (25[OH]D) concentration in patients with this condition is lacking. We conducted a multi-centre cross-sectional study in 278 COPD patients aged 41-92 years in London, UK. Details of potential environmental determinants of vitamin D status and COPD symptom control and severity were collected by questionnaire, and blood samples were taken for analysis of serum 25(OH)D concentration and DNA extraction. All participants performed spirometry and underwent measurement of weight and height. Quadriceps muscle strength (QS) was measured in 134 participants, and sputum induction with enumeration of lower airway eosinophil and neutrophil counts was performed for 44 participants. Thirty-seven single nucleotide polymorphisms (SNP) in 11 genes in the vitamin D pathway (DBP, DHCR7, CYP2R1, CYP27B1, CYP24A1, CYP27A1, CYP3A4, LRP2, CUBN, RXRA, and VDR) were typed using Taqman allelic discrimination assays. Linear regression was used to identify environmental and genetic factors independently associated with serum 25(OH)D concentration and to determine whether vitamin D status or genetic factors independently associated with % predicted forced expiratory volume in one second (FEV1), % predicted forced vital capacity (FVC), the ratio of FEV1 to FVC (FEV1:FVC), daily inhaled corticosteroid (ICS) dose, respiratory quality of life (QoL), QS, and the percentage of eosinophils and neutrophils in induced sputum. Mean serum 25(OH)D concentration was 45.4nmol/L (SD 25.3); 171/278 (61.5%) participants were vitamin D deficient (serum 25[OH]D concentration <50nmol/L). Lower vitamin D status was independently associated with higher body mass index (P=0.001), lower socio-economic position (P=0.037), lack of vitamin D supplement consumption (P<0.001), sampling in Winter or Spring (P for trend=0.006) and lack of a recent sunny holiday (P=0.002). Vitamin D deficiency associated with reduced % predicted FEV1 (P for trend=0.060) and % predicted FVC (P for trend=0.003), but it did not associate with FEV1:FVC, ICS dose, QoL, QS, or the percentage of eosinophils or neutrophils in induced sputum. After correction for multiple comparisons testing, genetic variation in the vitamin D pathway was not found to associate with serum 25(OH)D concentration or clinical correlates of COPD severity. Vitamin D deficiency was common in this group of COPD patients in the UK, and it associated independently with reduced % predicted FEV1 and FVC. However, genetic variation in the vitamin D pathway was not associated with vitamin D status or severity of COPD.

Abstract
Vitamin D deficiency is common in children with asthma, and it associates with poor asthma control, reduced forced expiratory volume in one second (FEV1) and increased requirement for inhaled corticosteroids (ICS). Cross-sectional studies investigating the prevalence, determinants and clinical correlates of vitamin D deficiency in adults with asthma are lacking. We conducted a multi-centre cross-sectional study in 297 adults with a medical record diagnosis of ICS-treated asthma living in London, UK. Details of potential environmental determinants of vitamin D status, asthma control and medication use were collected by questionnaire; blood samples were taken for analysis of serum 25(OH)D concentration and DNA extraction, and participants underwent measurement of weight, height and fractional exhaled nitric oxide concentration (FeNO), spirometry and sputum induction for determination of lower airway eosinophil counts (n=35 sub-group). Thirty-five single nucleotide polymorphisms (SNP) in 11 vitamin D pathway genes (DBP, DHCR7, RXRA, CYP2R1, CYP27B1, CYP24A1, CYP3A4 CYP27A1, LRP2, CUBN, VDR) were typed using Taqman allelic discrimination assays. Linear regression was used to identify environmental and genetic factors independently associated with serum 25(OH)D concentration, and to determine whether vitamin D status was independently associated with Asthma Control Test (ACT) score, ICS dose, FeNO, forced vital capacity (FVC), FEV1 or lower airway eosinophilia. Mean serum 25(OH)D concentration was 50.6nmol/L (SD 24.9); 162/297 (54.5%) participants were vitamin D deficient (serum 25(OH)D concentration <50nmol/L). Lower vitamin D status was associated with higher body mass index (P=0.014), non-White ethnicity (P=0.036), unemployment (P for trend=0.012), lack of vitamin D supplement use (P<0.001), sampling in Winter or Spring (P for trend <0.001) and lack of a recent sunny holiday abroad (P=0.030), but not with potential genetic determinants. Vitamin D status was not found to associate with any marker of asthma control investigated. Vitamin D deficiency is common among UK adults with ICS-treated asthma, and classical environmental determinants of serum 25(OH)D operate in this population. However, in contrast to studies conducted in children, we found no association between vitamin D status and markers of asthma severity or control.

Abstract
An efficient functioning placenta is essential for a healthy pregnancy and yet the way this is achieved has been the subject of much discussion and confusion, particularly with the occurrence of pathological conditions such as preeclampsia, morning sickness and hyperemesis/ptyalism gravidarum. We will attempt to explain the underlying physiology and the potential roles played by the placental tachykinins, neurokinin B and endokinin.

Abstract
BACKGROUND AND OBJECTIVE Interferon-gamma (IFN-γ)-inducible protein-10 (IP-10), soluble (s) CD163 and sCD14 play an important role in the pathogenesis of HCV and HIV infection and are involved in inflammation and liver fibrosis. The aim of the present study was to evaluate at a single time point, plasma soluble biomarkers and inflammatory monocytes subsets in different groups of subjects: (i) HIV monoinfected patients on suppressive ART; (ii) HIV/HCV coinfected patients on ART, with undetectable HIV viremia (including either subjects who had active HCV replication or those who cleared HCV); (iii) HCV monoinfected individual with active viral replication. METHODS Hundred and twenty-nine plasma samples were analyzed including HCV and HIV monoinfected patients, HIV/HCV coinfected patients, with active HCV infection (AHI) or with HCV viral clearance (VHC) and healthy donors (HD). Levels of IP-10, sCD163 and sCD14 were measured by ELISA. Absolute cell counts of monocyte subpopulations were enumerated in whole blood by using flow cytometric analyses. RESULTS IP-10 and sCD163 plasma levels were higher in HCV monoinfected and in AHI coinfected pts compared to HIV monoinfected and HD, whereas sCD14 levels were higher only in HIV monoinfected patients. Considering the degree of fibrosis, sCD163 and sCD14 levels positively correlated with kPa values (as assessed by fibroscan) and FIB-4 in HCV monoinfected group. On the other hand, IP-10 did not correlate with the fibrosis stage and it was found increased also in patients with low fibrosis. Moreover, we found an increase of the inflammatory NCM subset, in non-cirrhotic HCV subjects, while no alterations were observed in HIV, AHI and VHC. CONCLUSIONS Our study suggests a scenario in which active HCV infection is associated with a strong pro-inflammatory state, even in the initial stage of liver fibrosis, regardless the presence of HIV coinfection, thus underlying the need of an early anti-HCV treatment.

Abstract
BACKGROUND TNF-like weak inducer of apoptosis (TWEAK), its receptor fibroblast growth factor-inducible 14 (Fn14) and its scavenger receptor CD163 (sCD163) have known associations with many autoimmune diseases. However, the role of the TWEAK axis in autoimmune thyroid disease (AITD) remains unclear. Therefore, the aim of this study was to investigate the role of the TWEAK-Fn14 axis in the pathogenesis of AITD. METHODS Serum levels of soluble TWEAK (sTWEAK) and sCD163 were measured in 38 patients with Graves' disease (GD), 40 patients with Hashimoto's thyroiditis (HT) and 40 healthy controls (HCs). Additionally, the mRNA expression of TWEAK and Fn14 in peripheral blood mononuclear cells (PBMCs) was explored, and the protein expression of TWEAK and Fn14 in thyroid glands surgically removed from 10 patients with GD, 10 patients with HT and 10 HCs was studied by immunohistochemical staining. RESULTS The results showed that the serum levels of sTWEAK were significantly reduced in patients with HT and inversely correlated with antithyroid peroxidase antibody (TPOAb) levels. Additionally, high levels of sCD163 and a high sCD163/sTWEAK ratio were positively associated with the TPOAb levels in patients with HT and the thyrotropin receptor antibody (TRAb) levels in patients with GD. TWEAK mRNA expression and protein expression were upregulated in thyroid glands and PBMCs from patients with HT. CONCLUSION Expression of the TWEAK-Fn14 axis was upregulated in patients with AITD and might play a role in the pathogenesis of AITD.

Abstract
(Pro)renin receptor ((P)RR) is a multi-functional molecule that is related to both the renin-angiotensin system (RAS) and vacuolar H+-ATPase (v-ATPase), an ATP-dependent multi-subunit proton pump. Soluble (P)RR (s(P)RR), which consists of the extracellular domain of (P)RR, is present in blood and urine. Elevated plasma s(P)RR concentrations are reported in patients with chronic kidney disease and pregnant women with hypertension or diabetes mellitus. In addition, we have shown that plasma s(P)RR concentrations are elevated in patients with obstructive sleep apnea syndrome (OSAS). Interestingly, the levels are elevated in parallel with the severity of OSAS, but are not related to the presence of hypertension or the status of the circulating RAS in OSAS. It is known that v-ATPase activity protects cells from endogenous oxidative stress, and loss of v-ATPase activity results in chronic oxidative stress. We hypothesize that hypoxia and subsequent oxidative stress, perhaps in the brain, may be one of the factors that elevate plasma s(P)RR levels in OSAS.

Abstract
Supplemental Digital Content is available in the text. Objective— To establish the cellular source of plasma factor (F)XIII-A. Approach and Results— A novel mouse floxed for the F13a1 gene, FXIII-Aflox/flox (Flox), was crossed with myeloid- and platelet-cre–expressing mice, and cellular FXIII-A mRNA expression and plasma and platelet FXIII-A levels were measured. The platelet factor 4-cre.Flox cross abolished platelet FXIII-A and reduced plasma FXIII-A to 23±3% (P<0.001). However, the effect of platelet factor 4-cre on plasma FXIII-A was exerted outside of the megakaryocyte lineage because plasma FXIII-A was not reduced in the Mpl−/− mouse, despite marked thrombocytopenia. In support of this, platelet factor 4-cre depleted FXIII-A mRNA in brain, aorta, and heart of floxed mice, where FXIII-Apos cells were identified as macrophages as they costained with CD163. In the integrin αM-cre.Flox and the double copy lysozyme 2-cre.cre.Flox crosses, plasma FXIII-A was reduced to, respectively, 75±5% (P=0.003) and 30±7% (P<0.001), with no change in FXIII-A content per platelet, further consistent with a macrophage origin of plasma FXIII-A. The change in plasma FXIII-A levels across the various mouse genotypes mirrored the change in FXIII-A mRNA expression in aorta. Bone marrow transplantation of FXIII-A+/+ bone marrow into FXIII-A−/− mice both restored plasma FXIII-A to normal levels and replaced aortic and cardiac FXIII-A mRNA, while its transplantation into FXIII-A+/+ mice did not increase plasma FXIII-A levels, suggesting that a limited population of niches exists that support FXIII-A-releasing cells. Conclusions— This work suggests that resident macrophages maintain plasma FXIII-A and exclude the platelet lineage as a major contributor.

Abstract
Background The objective of this study was to explore the diagnostic and prognostic value of soluble triggering receptor expressed on myeloid cell 1 (sTREM-1), soluble cluster of differentiation 14 (sCD14), soluble cluster of differentiation 163 (sCD163), interleukin-6 (IL-6), procalcitonin (PCT), and C-reactive protein (CRP) serum levels for patients with severe sepsis and septic shock in an intensive care unit (ICU). Methods Fifty patients admitted at the ICU with the diagnosis of severe sepsis or septic shock were studied. SOFA and APACHE II scores as well as serum biomarkers were measured at days 0, 2 and 5. The influence of these variables on 28-day mortality was analyzed. Twenty healthy individuals served as controls. Results Baseline serum concentrations of sTREM-1, sCD163, IL-6 and PCT correlated with SOFA score. Only sTREM-1 levels correlated with APACHE II score. The 28-day mortality rate for all patients was 42%. The absence of risk factors for infection, presence of septic shock, baseline values of sCD14 and decrease of PCT and IL-6 from baseline to day 5 were variables associated to mortality in the univariate analysis. The unique independent factor associated to mortality in the multivariate analysis was a decrease of PCT higher than 50% from days 0 to 5. Conclusions Serum levels of sTREM-1 are correlated with the severity of sepsis. A 50% decrease of PCT was the unique variable associated with survival in the multivariate analysis.

Abstract
OBJECTIVE Pre-eclampsia, growth retardation and preterm delivery are the most common reasons leading to increased maternal and perinatal mortality. The increased expression of hypoxia induced factors, such as HIF-1, triggers the overexpression of anti-angiogenic genes. The aim of this study was to determine the transcriptional activity of individual pro- and anti-angiogenic markers (VEGF, HIF-1, sEng, Flt-1, PlGF-1) in maternal blood samples from patients with spontaneous preterm labor, preterm labor in combination with pre-eclampsia and fetal growth restriction in comparison with physiologically terminated pregnancies. PATIENTS AND METHODS The transcriptional activity of specific genes was detected from the blood of patients using the chromatin immunoprecipitation capture method coupled with quantitative real-time PCR. RESULTS The maximum differences in mRNA levels of PlGF-1 and VEGF-A were detected in two groups: the group of normal-term birth with complications and the group of preterm labor with complications (both significantly lower than the control, p < 0.001). In contrast, a marked increase of mRNA levels was found in the same groups of patients for the HIF-1, endoglin and Flt-1 genes (p < 0.001). CONCLUSIONS According to our results, we can conclude that increased oxidative stress, increasing the expression levels of anti-angiogenic genes and reduction of the transcriptional activity of pro-angiogenic genes can provide additional information during diagnostics of pathological complications of labor.

Abstract
AIMS Dipeptidyl peptidase-4 inhibitor (DPP-4i) is commonly used worldwide for the treatment of type 2 diabetes mellitus. In addition to its hypoglycemic activity, DPP-4i might have anti-inflammatory effects. In this study we examined the effects of DPP-4i on the serum levels of soluble CD163 (sCD163), a marker for activated macrophages, in individuals with type 2 diabetes mellitus. We compared these anti-inflammatory effects with those of α glucosidase inhibitor (αGI). METHODS Japanese patients with type 2 diabetes mellitus who were stably maintained on ≤2mg/day glimepiride alone were recruited and randomly assigned to receive additional sitagliptin (n=37) or αGI (n=37). Levels of sCD163 were measured before the addition and after a 24-week treatment period. RESULTS Addition of sitagliptin significantly reduced the serum sCD163 (632 vs. 575ng/mL, p<0.05), while αGI did not display this effect (624 vs. 607ng/mL). The changes in levels of sCD163 were not related to changes in either HbA1c or body mass index (BMI). CONCLUSIONS Our results suggested that DPP-4i might exert anti-inflammatory effects in individuals with type 2 diabetes mellitus, which are independent of its effects on glycemia and BMI.

Abstract
Background CD163, receptor for the haptoglobin–hemoglobin complex, is expressed on monocytes/macrophages and neutrophils. A soluble form of CD163 (sCD163) has been associated with the M2 macrophage phenotype, and M2 macrophages have been shown to down-modulate inflammatory responses. In particular, previous studies have shown that M2 is closely associated with the most severe clinical presentation of leprosy (i.e. lepromatous leprosy (LL)), as well as tuberculosis. We hypothesized that sCD163 correlates with severity of diseases caused by intracellular pathogens. Methodology/Principal findings To assess this hypothesis, sCD163 levels were measured in the serum of leprosy and visceral leishmaniasis (VL) patients stratified by severity of the clinical presentation. sCD163 levels were significantly higher in patients with these diseases than those observed in healthy control individuals. Further analyses on infection and disease status of leprosy and VL patients revealed a clear association of sCD163 levels with clinical parameters of disease severity. In vitro culture assays revealed that Leishmania infection induced CD163 expression on the surface of both monocyte/macrophages and neutrophils, suggesting these cells as possible sources of sCD163. FACS analyses shows that the cells expressing CD163 produces both TNF-α and IL-4. Conclusions/Significance Taken together, our results reveal sCD163 as a potential biomarker of severity of diseases caused by intracellular pathogens M. leprae and Leishmania spp. and have a modulatory role, with a mix of an inflammatory property induced by TNF-α release, but that potentially induces an anti-inflammatory T cell response, related to IL-4 release. Visceral leishmaniasis (VL) is a systemic, and most severe form of leishmaniasis. Soluble CD163 (sCD163) levels can serve as biomarker for disease severity in several inflammatory disorders. However, no linkage has been reported for its relationship with Leishmania infections. We now demonstrate, for the first time, that sCD163 is increased in VL patients, and its presence is directly correlated to clinical parameters of disease severity. In vitro infection of monocyte-derived macrophages and neutrophils with L. infantum and L. amazonensis induces, while BCG reduce the expression of CD163 on macrophage surface Furthermore, presence of sCD163 is reduced during clinical improvements. Taken together, results reveal an important role for sCD163 in immune modulation during disease progression, and suggest a potential role as biomarker for determining disease severity and clearance.

Abstract
Novel targets for action of the class IV semaphorin Seam4D have been identified in the immune system. The low-affinity CD72 receptor for Seam4D was detected not only on B lymphocytes, but also in a proportion of T cells, whereas the high-affinity semaphorin receptor, plexin B1, originally considered to belong to non-immune cells, proved to be in a great proportion of intact T and B cells. Seam4D is constitutively expressed in B cells, which, along with T cells, can serve as a source of both membrane and soluble semaphorin. The results obtained make significant adjustments in understanding of Seam4D effects in lymphoid cells.

Abstract
AIM To evaluate the numbers of different subsets of monocytes and their associations with the values of clinical measures in mild acute pancreatitis (MAP) patients.
METHODS The study included one group of 13 healthy controls and another group of 24 patients with new-onset MAP. The numbers of different subsets of monocytes were examined in these two groups of subjects by flow cytometry. The concentrations of plasma interleukin (IL)-10 and IL-12 were determined by cytometric bead array. The acute physiology and chronic health evaluation (APACHE) II scores of individual patients were evaluated, and the levels of plasma C-reactive protein (CRP) as well as the activities of amylase and lipase were measured.
RESULTS In comparison with that in the controls, significantly increased numbers of CD14+CD163-, CD14+CD163-MAC387+ M1 monocytes, but significantly reduced numbers of CD14+CD163+IL-10+ M2 monocytes were detected in the MAP patients (P < 0.01 or P < 0.05). Furthermore, significantly higher levels of plasma IL-10 and IL-12 were observed in the MAP patients (P < 0.01 for all). More importantly, the levels of plasma CRP were positively correlated with the numbers of CD14+CD163- (R = 0.5009, P = 0.0127) and CD14+CD163-MAC387+ (R = 0.5079, P = 0.0113) M1 monocytes and CD14+CD163+CD115+ M2 monocytes (R = 0.4565, P = 0.0249) in the patients. The APACHE II scores correlated with the numbers of CD14+CD163+CD115+ (R = 0.4581, P = 0.0244) monocytes and the levels of plasma IL-10 (R = 0.4178, P = 0.0422) in the MAP patients. However, there was no significant association among other measures tested in this population.
CONCLUSION Increased numbers of CD14+CD163- and CD14+ CD163-MAC387+ monocytes may contribute to the pathogenesis of MAP, and increased numbers of CD14+CD163+CD115+ monocytes may be a biomarker for evaluating the severity of MAP.

Abstract
BACKGROUND Carbohydrate antigen (CA19-9) is a well-established marker to monitor disease status after resection of pancreatic cancer. However, few serum markers have been reported to improve the prognostic ability of postoperative CA19-9, especially in patients with normal postoperative CA19-9. METHODS A total of 353 patients with pancreatic ductal adenocarcinoma treated by radical resection were reviewed retrospectively, and a prospective cohort including 142 patients with resectable pancreatic head carcinoma was analyzed as a validation cohort. Perioperative CA19-9 and postoperative serum markers (CEA, CA242, CA72-4, CA50, CA125, CA153, and AFP) were investigated. RESULTS Patients with postoperative normalization of CA19-9 had improved survival times (recurrence-free survival: 11.9 months; overall survival: 22.5 months) compared with those with decreased but still elevated postoperative CA19-9 (recurrence-free survival: 6.8 months, P < .001; overall survival: 13.5 months, P < .001) or those with increased postoperative CA19-9 (recurrence-free survival: 3.5 months, P < .001; overall survival: 7.9 months, P < .001), which was similar to those with consistently normal CA19-9 during perioperative periods (recurrence-free survival: 10.6 months, P = .799; overall survival: 24.1 months, P = .756). Normal postoperative CA19-9 levels were an independent indicator for a positive outcome after operation, regardless of preoperative CA19-9 levels. Elevated postoperative CEA and CA125 were identified further as independent risk factors for patients with normal postoperative CA19-9, while elevated postoperative CA125 and nondecreased postoperative CA19-9 were independent prognostic markers for patients with elevated postoperative CA19-9. CONCLUSION The postoperative monitoring of CEA and CA125 provided prognostic significance to the measurement of CA19-9 in pancreatic cancer after resection.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is a common endocrine complication in pregnancy. While it has been established that age, family history of diabetes, insulin resistance and several biomarkers are associated with GDM but significant gaps remain in understanding risk factors for GDM. Soluble pro-renin receptor (s [Pro] RR) as a biomarker reflects the activation of renin-angiotensin system in tissues which may be related to insulin resistance Objective: The aim of this study was to determine the role of (s [pro] RR) in predicting GDM. METHODS one hundred-eighty singleton pregnant women in first trimester were enrolled. We excluded women with previous history of GDM, hypertension and consumption of drugs affected reninangiotensin system. A fasting blood glucose and s (pro) RR level were obtained during first trimester and OGTT was performed at 24-28 weeks of gestation. We used ROC curves to identify s (pro) RR cutoff points for detecting GDM and the difference in s (pro)RR level was assessed in GDM and non- GDM women. RESULTS Among 180 women, 24 (13.33%) had GDM. There was no significant difference between age and body mass index in subjects with GDM compared to non- GDM. The concentration of s (pro) RR was significantly higher in GDM subjects rather than non- GDM [29.27(24.60-35.92) vs. 22.89(19.46- 24.27), P<0.001]. Multiple logistic regression analysis revealed a significant association of s(pro) RR with GDM (odd ratio: 1.32, 95% CI: 1.17-1.48, P=0.04). A cut-off point 24.52 ng/ml of s(pro) RR had 75% sensitivity and 80% specificity for predicting GDM. CONCLUSION Increased level of s (pro) RR in first trimester may be a marker for predicting GDM.
