Abstract
INTRODUCTION The aim of our study was to explore whether there is an association of serum sFas (cell death apoptosis receptor) concentrations during the first week of sepsis with sepsis severity and sepsis mortality. METHODS In this observational study, septic patients were recruited. Serum sFas concentrations were determined on days 1, 4, and 8 of sepsis diagnosis. Thirty-day mortality was the outcome variable. RESULTS Surviving patients (n = 181) compared to non-survivors (n = 101) presented lower serum sFas levels on day 1 (p < 0.001), day 4 (p < 0.001) and day 8 (p < 0.001), and lower SOFA on day 1 (p < 0.001), day 4 (p < 0.001) and day 8 (p < 0.001). Logistic regression analyses showed associations between 30-day mortality and serum sFas levels controlling for SOFA on day 1 (OR = 1.005; 95% CI = 1.003-1.007; p < 0.001), day 4 (OR = 1.044; 95% CI = 1.029-1.060; p < 0.001) and day 8 (OR = 1.012; 95% CI = 1.002-1.022; p = 0.02). CONCLUSIONS The association of serum sFas concentrations during the first week of sepsis with sepsis severity and sepsis mortality were our new findings.

Abstract
Apoptosis of macrophages infected by Mycobacterium tuberculosis via Fas-FasL is an important immune mechanism against infection. This study investigated the association of tuberculosis (TB) with the presence of the polymorphisms FAS -670A/G and FASL -124A/G, the levels of sFas and sFasL, and the gene expression of FASL and cytokines. Samples of 200 individuals diagnosed with TB and 200 healthy controls were evaluated. Real-time PCR (genotyping and gene expression) and ELISA (dosages of sFas, sFasL, IFN-γ, and IL-10) tests were performed. There was no association of FAS -670A/G and FASL -124A/G polymorphisms with TB. The TB group exhibited high plasma levels of sFas and reduced plasma levels of sFasL (p < 0.05). The correlation analysis between these markers revealed a positive correlation between the levels of sFas and sFasL, sFasL and FASL expression, and between sFas and FASL expression (p < 0.05). In the TB group, there was a positive correlation between FASL expression and IFN-γ levels and higher levels of IL-10 compared to IFN-γ (p < 0.05). High levels of sFas and reduced levels of sFasL and FASL expression may contribute to the inhibition of apoptosis in infected cells and represent a possible bacterial resistance resource to maintain the infection.

Abstract
BACKGROUND Fas is a major receptor for cell death by apoptosis. Higher blood concentrations of soluble Fas (sFas) have been reported in patients with ischemic stroke compared to control subjects. The aim of this study was to explore the existence or not of an association between blood sFas concentrations and mortality in patients with ischemic stroke. METHODS This study included patients admitted to Intensive Care Units with severe and malignant middle cerebral artery infarction (MCAI), defined as acute infarction, in more than 50% of this territory on computed tomography and less than 9 points on the Glasgow Coma Scale (GCS). Serum sFas levels were determined at the time of diagnosis of MMCAI. RESULTS Non-surviving severe MMCAI patients (n = 27) showed lower platelet count (p = 0.004), higher serum sFas (p < 0.001), and lower GCS (p = 0.001) compared to surviving patients (n = 27). Multiple logistic regression found an association of serum sFas levels and mortality at 30 days (OR = 1.015; 95% CI = 1.002-1.027; p = 0.02) after control for CGS and platelet count. CONCLUSIONS The main novelty of our study was the existence of an association between high blood sFas concentrations and mortality in patients with ischemic stroke.

Abstract
INTRODUCTION Scarce data on Fas, one of the main receptors that activates the apoptosis extrinsic pathway, in septic patients exists. Higher blood soluble Fas (sFas) concentrations in non-survivor septic patients compared with survivors have been found in small studies; however, the association of blood sFas concentrations with mortality controlling for sepsis severity has not been stablished due to this small sample size in those studies. Thus, our main objective study was to determine whether an association between blood sFas concentrations and sepsis mortality controlling for sepsis severity exists. METHODS We included septic patients in this observational and prospective study carried out in three Spanish Intensive Care Units. We obtained serum samples at sepsis diagnosis sepsis for sFas levels determination. RESULTS Thirty-day non-surviving patients (n=85) compared to surviving patients (n=151) had higher serum sFas levels (p<0.001). We found in multiple logistic regression analysis an association of serum sFas levels with mortality controlling for age and SOFA (OR=1.004; 95% CI=1.002-1.006; p<0.001), and for age and APACHE-II (OR=1.004; 95% CI=1.002-1.006; p<0.001). Serum sFas levels showed and area under the curve for mortality prediction of 71% (95% CI=65-71%; p<0.001). Kaplan-Meier analysis showed higher mortality rate in patients with serum sFas levels>83.5ng/mL (Hazard ratio=3.2; 95% CI=2.1-5.0; p<0.001). CONCLUSIONS That an association between blood sFas concentrations and sepsis mortality controlling for sepsis severity exists was our main new finding study.

Abstract
Background: There are no data on circulating concentrations of sFas (proapoptotic protein of extrinsic pathway) and Bcl2 (antiapoptotic protein of intrinsic pathway) in COVID-19 patients. Thus, our objective study was to determine whether an association exists between serum concentrations of sFas and Bcl2 and COVID-19 patient mortality.Methods: This observational and prospective study of COVID-19 patients was performed in eight Intensive Care Units (ICU) from Canary Islands (Spain). Serum levels of sFas and Bcl2 at ICU admission were determined. Mortality at 30 days was the end-point study.Results: Surviving patients (n = 42) compared to non-surviving (n = 11) had lower APACHE-II (p < 0.001), lower SOFA (p = 0.004), lower serum sFas levels (p = 0.001) and higher serum Bcl2 levels (p < 0.001). Logistic regression showed an association between high serum sFas levels and mortality after controlling for APACHE-II (OR = 1.004; 95% CI = 1.101-1.007; p = 0.01) or SOFA (OR = 1.003; 95% CI = 1.101-1.106; p = 0.004), and between low serum Bcl2 levels and mortality after controlling for APACHE-II (OR = 0.927; 95% CI = 0.873-0.984; p = 0.01) or SOFA (OR = 0.949; 95% CI = 0.913-0.987; p = 0.01).Conclusions: Thus, to the best of our knowledge, this is the first study reporting blood levels of sFas and Bcl2 in COVID-19 patients and its association with mortality.

Abstract
Antinuclear antibodies (ANA) are currently considered as an epiphenomenon of apoptotic processes, possibly in control of autoreactivity in patients with multiple sclerosis (MS). Apoptosis of reactive lymphocytes by the Fas/FasL system is described as an effective control mechanism for autoreactivity in MS. We aimed to provide a context to the potential link between ANA and peripheral lymphocyte apoptosis in MS. The presence of ANA was detected in sera by immunofluorescence assay, and concentrations of sFas and sFasL were determined in the sera of 44 and cerebrospinal fluid (CSF) of 11 relapsing-remitting (RR) MS patients using cytometric bead-based array, and their association with the disease characteristics was determined. ANA were detected in the sera of 43.2% of RRMS patients, and their frequency was the highest in patients with disease duration of less than one year (88,89%). In addition, the number of experienced relapses was lower in ANA-positive patients. Concentrations of sFasL were inversely associated with patients' expanded disability status scale (EDSS) scores. Low concentrations of both soluble factors strongly discriminated patients with moderate to severe disability, from patients with mild or absent disability only in a group of patients with prolonged disease duration (>10 years). Both soluble mediators were significantly higher in ANA-positive patients. FasL concentrations were inversely associated with the number of relapses. There is a potential link between the presence of ANA and peripheral lymphocyte apoptosis mediated by Fas/FasL system in MS, whose precise role and significance needs to be determined by future mechanistic studies.

Abstract
As liver biopsy in children poses inherent risks, noninvasive measures of liver fibrosis are needed. This was a cross-sectional, liver biopsy validation pilot study of 16 participants evaluating the ability of shear wave elastography, aspartate transaminase to platelet ratio index (APRI), fibrosis index based on the 4 factors, and novel serum biomarkers to stage liver fibrosis in children with chronic hepatitis B or C. There was very high intrasegmental shear wave speed variation in our participants and little correlation with fibrosis. APRI and monocyte chemoattractant protein (MCP-1) were higher in fibrosis stage F2-3 versus F0-1 (P = .02, P = .06, respectively). Soluble Fas (sFas) was lower in F2-3 versus F0-1 (P = .046). A logistic regression analysis calculated by (APRI × MCP-1)/sFas demonstrated an area under the receiver operating characteristic curve of 0.92 (P < .001), suggesting that this combination can differentiate fibrosis stage F0-1 from F2-3 in children with chronic viral hepatitis.

Abstract
Background: Hepatitis B virus (HBV) infection is a leading cause of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma worldwide. Due to their shared routes of transmission, approximately 10% of HIV-infected patients worldwide are chronically coinfected with HBV. Additionally, liver disease has become a major cause of morbidity and mortality in HBV/HIV coinfected patients due to prolonged survival with the success of antiretroviral therapy. The relationship between immune exhaustion markers (PD-1/PD-L1) and apoptotic markers such as Fas/FasL, TGFβ1, TNF-α, and Th1/Th2 cytokines are not clearly delineated in HBV/HIV coinfection. Methods: Levels of soluble Fas/FasL, TGFβ1, TNF-α, and sPD-1/sPD-L1 as well as Th1 and Th2 cytokines were evaluated in the sera of HBV-monoinfected (n = 30) and HBV/HIV-coinfected (n = 15) patients and compared to levels in healthy controls (n = 20). Results: HBV-monoinfected patients had significantly lower levels of the anti-inflammatory cytokine IL-4 (P < 0.05) and higher levels of apoptotic markers sFas, sFasL, and TGFβ-1 (P < 0.001) compared to healthy controls. Coinfection with HIV was associated with higher levels of sFas, TNF-α, and sPD-L1 (P < 0.005), and higher levels of the pro-inflammatory cytokines IL-6, IL-8, and IL-12p70 (P < 0.05) compared to healthy controls. Patients with HBV infection had a unique biomarker clustering profile comprised of IFN-γ, IL12p70, IL-10, IL-6, and TNF-α that was distinct from the profile of the healthy controls, and the unique HIV/HBV profile comprised GM-CSF, IL-4, IL-2, IFN-γ, IL12p70, IL-7, IL-10, and IL-1β. In HBV monoinfection a significant correlation between sFasL and PD1(r = 0.46, P = < 0.05) and between sFas and PDL1 (r = 0.48, P = <0.01) was observed. Conclusion: HBV-infected and HBV/HIV-coinfected patients have unique apoptosis and inflammatory biomarker profiles that distinguish them from each other and healthy controls. The utilization of those unique biomarker profiles for monitoring disease progression or identifying individuals who may benefit from novel immunotherapies such as anti-PD-L1 or anti-PD-1 checkpoint inhibitors appears promising and warrants further investigation.

OBJECTIVES The the study was to estimate the concentrations of antiapoptotic sFas and pro-apoptotic FasL in the serum of pregnant women in the third trimester of pregnancy and in the cord blood serum of neonates from vein and arteries separately. The correlation could be crucial for evaluation of apoptosis process intensity in placenta and the role of fetal blood circulation system on distribution of sFas and FasL. MATERIAL AND METHODS The study group consisted of 28 pregnant women in physiological pregnancy, between 38- 41 weeks. Vein blood was taken from maternal elbow vein and umbilical cord, separately from vein and arteries. The research was done by sets for sFas and FasL from R&D Systems Elisa kit. RESULTS In arterial and vein cord blood there were much more lower concentrations of sFas than in maternal blood-arterial cord blood 3351.78 pg/mL, vein cord blood 3351.78 pg/mL versus maternal blood 5769.62 pg/mL (p < 0.001). No differ-ence was found in sFas concentrations between cord arterial and vein blood sera. Statistical difference was found between mean concentration of Fas ligand in maternal blood serum (71.36 pg/mL) and arterial cord blood serum (164.57 pg/mL) p < 0.05 (p = 0.001). Cord arterial blood serum showed much higher concentrations of FasL than maternal blood serum. No difference was found between cord arterial and vein blood sera concentrations of FasL: 164.57 pg/mL vs. 170.00 pg/mL (p = 0.701). CONCLUSIONS Obtained results suggest no influence of sFas and FasL production on fetal organism apoptosis. Lowering of sFas concentration in fetal blood could mean the increase of apoptosis in fetal organism compared to maternal. Higher concentration of FasL in cord blood than in mothers suggests higher apoptosis intensification in fetal circulation and no influence of blood flow across placenta on its concentration.

Abstract
BACKGROUND Implantable cardioverter-defibrillator (ICD) shocks are potentially associated with myocardial injury, altered hemodynamics, apoptosis, and inflammatory signaling. Their precise cellular impact can be explored after defibrillation testing (DFT) via biomarkers. We evaluated changes in biomarkers after ICD shocks during DFT. METHODS We prospectively enrolled outpatients presenting for first implantation of a cardiac device. Biomarkers indicative of myocardial injury, inflammation, and apoptosis were measured before and after implantation, and compared between patients receiving DFT (DFT+) to those not (DFT-). RESULTS Sixty-three patients were enrolled, 40 in the DFT+ group and 23 in the DFT- group. Average levels of troponin I, hsCRP, Calprotectin, N-terminal pro B-type natriuretic peptide (NTproBNP), and sFas increased by >50% after cardiac device implantation compared to baseline. Increase in troponin never exceeded the 50-fold upper limit of normal (2 ng/mL). Troponin trended higher in the DFT+ group at 8 hours (median 0.18 ng/mL, interquartile range [IQR] 0.11-0.48) versus the DFT- group (0.10 ng/mL, IQR 0.06-0.28, P = 0.0501); NTproBNP had a similar trend (P = 0.0581). sFas significantly increased in the DFT+ group from baseline (median 4663 pg/mL, IQR 2908-5679) to 24 hours (5039 pg/mL, IQR 3274-6261; P = 0.0338) but not in the DFT- group (P = 0.4705). CONCLUSION DFT testing is associated with acutely increased plasma levels of troponin and sFas, a biomarker of apoptosis, along with a trend toward higher NTproBNP.

Abstract
CONTEXT Epithelial-mesenchymal transition (EMT) leads to renal fibrosis and chronic kidney disease (CKD). OBJECTIVE The aim of this study was to assess the usefulness of survivin, E-cadherin and metalloproteinases (MMPs) as biomarkers of CKD-related complications. MATERIAL AND METHODS Survivin, E-cadherin, MMP-2, MMP-9 and TGFbeta1 were assessed by ELISA in 41 children with CKD stages 3 to 5 and in 23 controls. RESULTS The serum and urine values of analyzed parameters were significantly elevated in CKD patients versus controls and correlated with each other. CONCLUSIONS The observed parameter changes indicate apoptosis, tissue remodeling and fibrosis in CKD children. Urine survivin may become a new biomarker of kidney-specific EMT.

Abstract
Assessments of disease activity and organ damage in systemic lupus erythematosus (SLE) remain challenging because of the lack of reliable biomarkers and disease heterogeneity. Ongoing inflammation can be difficult to distinguish from permanent organ damage caused by previous flare-ups or medication side effects. Circulating soluble urokinase plasminogen activator receptor (suPAR) has emerged as a potential marker of inflammation and disease severity, and an outcome predictor in several disparate conditions. This study was done to evaluate suPAR as a marker of disease activity and organ damage in SLE. Sera from 100 healthy donors and 198 patients with SLE fulfilling the 1982 American College of Rheumatology classification criteria and/or the Fries criteria were analyzed for suPAR by enzyme immunoassay. Eighteen patients with varying degree of disease activity were monitored longitudinally. Disease activity was assessed by the SLE disease activity index 2000 and the physician's global assessment. Organ damage was evaluated by the Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index (SDI). Compared with healthy control subjects, serum suPAR levels were elevated significantly in patients with SLE. No association was recorded regarding suPAR levels and SLE disease activity in cross-sectional or consecutive samples. However, a strong association was observed between suPAR and SDI (P < 0.0005). Considering distinct SDI domains, renal, neuropsychiatric, ocular, skin, and peripheral vascular damage had a significant effect on suPAR levels. This study is the first to demonstrate an association between serum suPAR and irreversible organ damage in SLE. Further studies are warranted to evaluate suPAR and other biomarkers as predictors of evolving organ damage.

Abstract
The effects of environmental tobacco smoke (ETS) are less studied especially on neonates. This study evaluates the clinical and biochemical effects in neonates exposed to ETS during pregnancy. Two hundred pregnant women asked to complete the questioners about their ETS. Ninety from them were enrolled in biochemical assays as two groups according to ETS. The cotinine level determined in saliva and serum of mothers to confirm their tobacco exposure. The routine tracheal suction from the fetus was used to determine the level of neuron specific enolase (NSE), soluble E-cadherin, sApo-1/Fas, nitric oxide (NO) and cotinine. In clinical assessment, the percent of full term babies in non-exposed group (72 %) are higher compared to exposed group (67 %). Apgar score at the first min, admission to intensive care unit (ICU) and morbidity during the first month shows statistical significance increase in exposed compared to non-exposed group (p = 0.03, 0.05, 0.01, respectively). The new born weight in exposed group significantly decreased compared to non-exposed group (2,850 g ± 3.74 vs 2,967.67 g ± 3.34; p = 0.02). In biochemical assessment, NSE and sE-cadherin significantly increased, while NO significantly decreased (p = 0.000) in exposed compared to non-exposed group. There is a positive correlation between level of cotinine and both NSE, sE-cadherin (r = 0.7, 0.9; p = 0.000, 0.006, respectively). To our knowledge, this is the first study link between prenatal tobacco exposure (PTE) and biochemical parameters measured in tracheal suction. PTE will lead to decrease in birth weight most probably by decreasing NO, sFas, and increasing sE-cadherin. While, increased morbidity of neonates in the exposed group could be attributed to cessation of breast feeding and its complication and increased NSE in the studied markers.

Abstract
PURPOSE To investigate whether serum levels of soluble Fas (sFas) and interleukin-6 (IL-6) could function as an index of the efficacy of steroid pulse treatment, we examined the serum level of these proteins before and after steroid pulse treatment in thyroid-associated ophthalmopathy patients. METHODS We gathered the blood of thyroid-associated ophthalmopathy patients before or after steroid pulse treatment, obtained serum with a centrifuge, and measured the serum levels of sFas and IL-6 by enzyme-linked immunosorbent assay (ELISA). RESULTS There was no difference in serum IL-6 value between pre- and poststeroid pulse treatment. Serum sFas value was significantly decreased in both pre- and poststeroid pulse treatment. Furthermore, there was a recognizable improvement in the degree of the extraocular muscle thickening after treatment in cases in whom the serum sFas value was lower than 3 ng/ml prior to the beginning of the therapy. In patients who had a serum sFas value of more than 3 ng/ml, there was no improvement in the degree of thickening of the extraocular muscle. CONCLUSIONS Serum level of sFas is an accurate index of the outcome of steroid pulse treatment in thyroid-associated ophthalmopathy and may become a useful index to gauge the status of convalescence.
