Abstract
BACKGROUND There is a crucial balance between oxidant and antioxidant defense mechanisms. We aimed to evaluate the role of the balance of these systems in children with bloodstream infection. METHODS We analyzed prospectively oxidant and antioxidant stress parameters from serum samples of children with BSI besides demographic and clinical data of children. Serum levels of the total antioxidant status (TAS), total oxidant status (TOS), albumin, plasma thiol, disulphide, catalase (CAT), myeloperoxidase (MPO), ischemia-modified albumin (IMA) levels, ferroxidase and arylesterase (ARES) activity were evaluated in both patients and healthy controls. RESULTS A total of 113 children were evaluated, 50 of them had bacteremia and the remaining 63 were healthy subjects. The median TOS values were 18.5 µmol H2O2/L and 13.1 µmol H2O2/L in patient and control groups, respectively with a statistically significant difference between groups. The mean serum IMA levels were 0.8±0.1 absorbance unit (ABSU) in patients and 0.5±0.09 ABSU in control, the difference between groups was statistically significant. The native thiol, total thiol levels and the disulphide levels were significantly lower in the patient group as compared with the control group. The myeloperoxidase level was 136 U/L in patients and 107 in controls with a statistically significant difference between groups. CONCLUSIONS TOS, IMA, MPO, and particularly plasma thiols seem good candidates for accurate diagnosis of bacteremia in children.

Abstract
Background and purpose The pathogenesis of idiopathic sudden sensorineural hearing loss (ISSNHL) is still unclear, and there is no targeted treatment. This research aimed to verify the role of oxidative stress in ISSNHL and explore whether melatonin has a protective effect on hearing. Materials and methods A total of 43 patients with ISSNHL and 15 healthy controls were recruited to detect the level of melatonin, reactive oxygen species (ROS), and total antioxidant capacity (TAC) in the blood and compared before and after treatment. Multivariate logistic regression models were performed to assess the factors relevant to the occurrence and improvement of ISSNHL. Results The patients with ISSNHL showed significantly higher ROS levels than controls (4.42 ± 4.40 vs. 2.30 ± 0.59; p = 0.031). The levels of basal melatonin were higher (1400.83 ± 784.89 vs. 1095.97 ± 689.08; p = 0.046) and ROS levels were lower (3.05 ± 1.81 vs. 5.62 ± 5.56; p = 0.042) in the effective group as compared with the ineffective group. Logistic regression analysis showed that melatonin (OR = 0.999, 95% CI 0.997-1.000, p = 0.049), ROS (OR = 1.154, 95% CI 1.025-2.236, p = 0.037), and vertigo (OR = 3.011, 95% CI 1.339-26.983, p = 0.019) were independent factors associated with hearing improvement. Besides, the level of melatonin (OR = 0.999, 95% CI 0.998-1.000, p = 0.023) and ROS (OR = 3.248, 95% CI 1.109-9.516, p = 0.032) were associated with the occurrence of ISSNHL. Conclusion Our findings may suggest oxidative stress involvement in ISSNHL etiopathogenesis. The level of melatonin and ROS, and vertigo appear to be predictive of the effectiveness of hearing improvement following ISSNHL treatment.

Abstract
Abstract
Objective Oxidative stress and antioxidants play an important role in infections' response. We aimed to investigate the potential association between oxidative stress and the pathogenesis of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection.
Methods We analyzed oxidant and antioxidant parameters from serum samples of children with novel corona virus disease 2019 (COVID-19) besides demographic and clinical data of children. Serum levels of the 8-hydroxy deoxyguanosine (8-OHdG), protein carbonyl (CO), malondialdehyde (MDA), total glutathione (GSH), superoxide dismutase (SOD), catalase (CT), and glutathione peroxidase (GPx) enzyme activities were evaluated and compared between groups.
Discussion A total of 96 children were evaluated, including 32 patients with confirmed COVID-19 (group 1), 35 patients with symptomatic infections without COVID-19 (group 2), and 29 healthy patients as a control group (group 3). Group 1 included 7 (21.8%) asymptomatic, 22 (68.7%) mild, and 3 (9.5%) moderate patients according to the severity of the disease. In all groups, there were no significant differences in oxidative stress and antioxidant parameter levels (p > 0.05). Furthermore, no statistical difference was found when the parameters of patients with COVID-19 and healthy children were evaluated according to disease course.
Conclusion Serum levels of oxidant and antioxidant parameters were similar in children infected with SARS-CoV-2 and other infectious agents. However, further studies, including children with severe to critical disease, are necessary to characterize the oxidative stress, antioxidants, cytokine responses in COVID-19, and elucidate the pathogenesis.

Abstract
BACKGROUND A crucial balance exists between oxidant and antioxidant mechanisms in the functional immune system. We aimed to evaluate the contributions of balance between these systems to coronavirus disease 2019 (COVID-19), a devastating pandemic caused by viral infection. METHOD We analyzed serum oxidant and antioxidant stress parameters according to the clinical and demographic characteristics of children and adults with COVID-19 and compared them against the values of healthy controls. Serum native thiol (NT), total thiol (TT), disulfide, total antioxidant status, total oxidant status, and ischemia-modified albumin levels were evaluated and compared between groups. RESULTS A total of 79 children and 74 adults were evaluated in the present study, including 46 children and 40 adults with COVID-19, 33 healthy children, and 34 healthy adults. TT, NT, and disulfide levels were significantly lower in the adult COVID-19 group than in all other groups (p = .001, p = .001, and p = .005, respectively). Additionally, TT and NT levels were significantly lower in both pediatric and adult COVID-19 cases with severe disease course than mild/moderate course. TT and NT levels were identified as predictors for the diagnosis of the adult COVID-19 cases and as independent predictors for disease severity in both children and adults with COVID-19. CONCLUSION Parameters that reveal the oxidant and antioxidant capacity, including TT and NT, appear to be good candidates for the accurate prediction of the clinical course among patients with COVID-19.

Abstract
Abstract
Objective The balance between oxidant and antioxidant defense mechanisms is crucial. In this article, we aimed to evaluate the role of this balance in community-acquired pneumonia (CAP) in children.
Methods We analyzed serum oxidant and antioxidant stress parameters according to the clinical and demographic data of children with CAP and compared them with healthy controls. Serum total antioxidant status (TAS) and total oxidant status (TOS) were evaluated and compared between the groups, along with levels of ischemia-modified albumin (IMA), antioxidant enzymes, nonenzymatic antioxidant factors, and plasma thiol.
Results Of 160 children evaluated, 106 had CAP (54 outpatients and 52 inpatients), and the other 54 were healthy (control group). Total thiol and native thiol levels were significantly lower in the inpatient group compared with the outpatient group (p = 0.004 and p = 0.005, respectively). Serum IMA differed significantly among the groups (p = 0.001), with inpatients showing the highest level. A positive correlation was found between serum IMA and C-reactive protein levels in patients with pneumonia (r = 0.351; p = 0.001).
Conclusion Parameters that provide information about antioxidant capacity may be useful in the diagnosis and prognosis of pneumonia. Our results suggest that plasma thiol levels and IMA may be good candidate biomarkers to predict hospitalization for CAP in children.

Abstract
Host response to infection is a major determinant of disease severity in Ebola virus disease (EVD), but gene expression programs associated with outcome are poorly characterized. Collaborative Cross (CC) mice develop strain-dependent EVD phenotypes of differential severity, ranging from tolerance to lethality. We screen 10 CC lines and identify clinical, virologic, and transcriptomic features that distinguish tolerant from lethal outcomes. Tolerance is associated with tightly regulated induction of immune and inflammatory responses shortly following infection, as well as reduced inflammatory macrophages and increased antigen-presenting cells, B-1 cells, and γδ T cells. Lethal disease is characterized by suppressed early gene expression and reduced lymphocytes, followed by uncontrolled inflammatory signaling, leading to death. We apply machine learning to predict outcomes with 99% accuracy in mice using transcriptomic profiles. This signature predicts outcomes in a cohort of EVD patients from western Africa with 75% accuracy, demonstrating potential clinical utility.

Abstract
The etiology of sudden hearing loss (SHL) has not been fully elucidated. Previous studies claimed that different etiological factors may play a role in the pathogenesis of SHL. The aim of the present study is to investigate the presence of oxidative stress (OS) in SHL cases using thiol-disulfide balance. In addition, total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI) and lipid hydroperoxide levels (LOOH) were investigated. A total of 30 cases (15 female, 15 male, mean age 48.9 ± 8.1 years, age range: 36-68 years) were included in the study. Thiol and disulfide amounts, thiol/disulfide ratios, TOS, TAS, OSI and LOOH scores of the case group and control group were compared. Native thiol (SH) and total thiol (SH + SH) values were significantly lower in the SHL group than in the control group (p = 0.028 and p = 0.044, respectively). The LOOH value, TOS value and OSI value were significantly higher in the SHL group than in the control group (all p values < 0.05). The TAS value was significantly lower in the SHL group than in the control group (p = 0.0001). The present study has presented that the thiol-disulfide balance was impaired in SHL cases. OS may play a role in the development of SHL.

Abstract
INTRODUCTION Crimean-Congo haemorrhagic fever (CCHF) is an acute viral haemorrhagic disease. Reactive oxygen species that are mainly generated by the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) enzyme family have a pivotal role in the pathophysiology of many diseases. The serum levels of NOX isoforms in patients with CCHF have yet to be assessed. METHODS This prospective study was conducted at Cumhuriyet University, Turkey. Only patients with CCHF confirmed by the National Reference Virology Laboratory were enrolled in the study. The study subjects comprised 67 CCHF patients and 70 healthy control subjects. The quantitative sandwich ELISA technique was used for the determination of serum NOX 1, 2, 4 and 5. RESULTS Higher median median NOX-1 (P=0.001) and NOX-5 (P<0.001) levels were found in patients compared to the control group. Higher median serum NOX-5 levels were found in the low-grade disease group compared to the intermediate-high disease group according to two different severity scores (P=0.003). Negative correlations were also found between the serum NOX-5 levels and the severity scores [(P<0.05, r=-0.259), (P<0.01, r=-0.417)]. The area under the curve (AUC) values for the NOX-1 and NOX-5 were 0.67 (confidence interval: 0.58-0.75) and 0.99 (confidence interval: 0.95-1.00), respectively. Lower NOX-5 levels were found in patients receiving thrombocyte suspension (P=0.004)Conclusions. NOX-5 may have a protective effect on CCHF patients and the measurement of serum NOX-5 levels may be used as a novel biochemical test in the diagnosis of CCHF.

Abstract
CONTEXT Crimean-Congo haemorrhagic fever (CCHF) is a life-threatening acute febrile haemorrhagic disease. OBJECTIVE This study was to measure levels of the oxidative stress biomarkers malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) and of CA I-II autoantibodies as biomarkers for autoimmunity and course of disease in patients with CCHF. METHODS Seventy CCHF patients and 39 healthy control volunteers were included in the study. RESULTS Serum MDA and TAS levels were significantly higher (p < .0001) and serum TOS and OSI levels were significantly lower (p < .0001) in both the acute period and at 6th-month follow-up in the CCHF patients compared to the healthy volunteers. CA II levels were significantly higher in the acute period compared to the healthy volunteers (p < .005) and were significantly lower at 6th-month follow-up (p < .05). CONCLUSION Serum MDA and CA II autoantibodies appear to reflect oxidative stress status and disease progression in CCHF and may be used as biomarkers for oxidative stress and disease progression.

Abstract
OBJECTIVES Crimean Congo hemorrhagic fever (CCHF) is the second most common hemorrhagic fever worldwide. This study aimed to evaluate the oxidant-antioxidant balance of patients with CCHF by detecting dynamic thiol disulfide homeostasis (TDH), which is a novel oxidative stress marker, and other molecules, including paraoxonase (PON), arylesterase (ARES), ceruloplasmin (CLP), myeloperoxidase (MPO), and catalase. METHODS This retrospective, cross-sectional, controlled study, which involved patients with CCHF and healthy volunteers, measured dynamic TDH using a novel automated method developed by Erel. RESULTS We recruited 69 adult patients with CCHF (31 females, 38 males, median age 46 years). The case fatality rate was 1.49% (1/69). Increased disulfide/native thiol and disulfide/total thiol ratios, decreased total antioxidant status (TAS), and increased total oxidant status (TOS) were found in patients with CCHF. TAS, PON, and ARES values were found to be positively correlated with both native and total thiol levels, whereas TOS and CLP were negatively correlated with both, at a significant level. MPO activity was similar in both groups. DISCUSSION This is the first study in the literature to evaluate dynamic TDH in CCHF. TDH shifts to the oxidative side in patients with CCHF, leading to an increase in TOS.

Abstract
OBJECTIVE Thiol-disulphide homeostasis (TDH) has a critical role in various clinical disorders. We aimed to assess the association of TDH with acute tonsillopharyngitis (AT) in children. METHODS This study included 94 (73 viral and 21 bacterial) tonsillopharyngitis patients and 88 control children. Their native thiol, total thiol, and disulphide levels were measured. RESULTS Viral and bacterial tonsillopharyngitis patients had lower native thiol levels compared with healthy children (P < 0.001 and P = 0.008, respectively). Both groups had lower total thiol levels compared with control children (P = 0.002 for viral, P = 0.011 for bacterial). The disulphide levels were lower in bacterial than in viral tonsillopharyngitis patients (P = 0.04), and there was a significant difference between viral tonsillopharyngitis patients and the control group (P < 0.001). The native/total thiol ratio in each patient group was lower than in the control group (P < 0.001 for viral, P = 0.017 for bacterial). The disulphide/native thiol and disulphide/total thiol ratios were significantly higher in viral (P < 0.001 for both) and bacterial tonsillopharyngitis patients (P = 0.017 for both) than in healthy children. In all patients, a correlation was found between the levels of C-reactive protein (CRP) and native thiol (r = -0.211, P = 0.04), CRP and total thiol (r = -0.217, P = 0.036), white blood cell (WBC) and native thiol (r = -0.228, P = 0.002), WBC and total thiol (r = -0.191, P = 0.01), and WBC and disulphide (r = 0.160, P = 0.03). DISCUSSION TDH is altered in AT in children. The alteration is more prominent in viral than in bacterial tonsillopharyngitis.
