Abstract
Periodontitis progression is associated with a host response in which anti-inflammatory and pro-inflammatory cytokine networks play a key role. Smoking is involved in the production of various mediators. The study aims to evaluate the levels of IL-17 and IL-35 in saliva and gingival crevicular fluid (GCF), to investigate the effects of smoking on these cytokines in smoker and non-smoker periodontitis patients. 19 smokers with periodontitis, 20 non-smokers with periodontitis, and 18 periodontally healthy subjects were included in the study. Periodontal clinical indexes were recorded and the levels of IL-17 and IL-35 in saliva and GCF were analyzed. No significant difference was detected among the groups in terms of salivary IL-17 and IL-35 levels. GCF IL-17 and IL-35 concentration levels in the non-smoker periodontitis group were significantly lower than the others (p < 0.05). Total levels of GCF IL-17 were significantly higher in both periodontitis groups than the control group; and total levels of GCF IL-35 were significantly higher in non-smoker periodontitis group than the others (p < 0.05). A positive correlation was detected between the salivary IL-17 and IL-35 levels (r = 0.884), GCF IL-17 and IL-35 concentrations (r = 0.854), and total GCF IL-17 and IL-35 (r = 0.973) levels (p < 0.01). The present study revealed a positive correlation between the IL-35 and IL-17 levels both in saliva and GCF. IL-17 and IL-35 can be considered as one of the cytokines that play a role in periodontal health and periodontitis; and smoking may be among the factors that affect the levels of these cytokines in GCF and saliva.

Abstract
Neutrophils are an essential member of the innate immune system derived from the myeloid stem cell series and develop in the bone marrow. The action of neutrophils defined in immune response includes phagocytosis, degranulation, cytokine production, and neutrophil extracellular traps. The success of the host immune defense depends on effective neutrophil activation. Recent studies have shown that neutrophils that have completed their task in the field of inflammation rejoin circulation. Uncontrolled inflammatory response and dysregulated immune responses to the host are important factors in the development of acute and chronic diseases. Neutrophils are the first cells to be drawn into the field at the time of inflammation. They have developed response strategies that produce proinflammatory cytokines and are known as neutrophil extracellular traps since they create mesh-like structures with their DNA contents into the external environment and release their granular proteins in this way. This article summarizes numerous recent studies and reviews the role of neutrophil extracellular traps in autoimmune and autoinflammatory diseases in the hope, that this will lead to the development of more effective treatments. In addition, in this review, the role of neutrophil extracellular trap formation in some pediatric autoimmune diseases is emphasized.

Abstract
OBJECTIVES This study aimed to evaluate the long-term antibody kinetics after vaccinating with an inactivated COVID-19 Vero cell vaccine (CoronaVac) in healthcare workers (HCWs) at a single center in Turkey. METHODS For this prospective observational study, Chemiluminescence immunoassay (CLIA) and enzyme-linked immunosorbent assay (ELISA) were used for the determination of binding antibodies (bAb) and neutralizing antibodies (nAb), respectively. Antibody kinetics were compared for the potential influencing factors, and propensity score analysis was performed to match the subcohort for age. RESULTS Early bAb and nAb response was achieved in all 343 participants. Titers of bAbs against SARS-CoV-2 on 42 days post-vaccination (dpv) were higher in HCWs who were aged <40 years and who had a history of COVID-19. SARS-CoV-2 bAb levels in HCWs on days 42 (n = 97), 90 (n = 97), and 180 (n = 97) were 175 IU/ml (3.9-250), 107 IU/ml (2.4-250), and 66.1 IU/ml (2.57-250), respectively (p<0.001). SARS-CoV-2 bAb (p<0.001) and nAb (p<0.001) titers decreased significantly over time. There was a high negative correlation between SARS-CoV-2 antibody titers and inverse optic density of nAb responses (Pearson correlation coefficient: -0.738, p<0.001). CONCLUSIONS When the antibody responses were compared, it was seen that the vaccine immunogenicity was better in those who had prior COVID-19 history and were aged <40 years. In the course of time, it was determined that there was a significant decrease in bAb and nAb responses after the 90th day. These results may guide approval decisions for booster COVID-19 vaccines.

Abstract
BACKGROUND It has been shown that functional status of dendritic cells (DCs) in diabetic patients with unstable angina pectoris (UAP) are more mature and activated than diabetic patients without coronary artery disease (CAD) and none diabetic patients with UAP. Accordingly we aimed to assess the activation of DCs in patients with CAD with/and without Diabetes Mellitus (DM) and compare to those in subjects with normal coronary arteries (NCA). MATERIALS AND METHODS Twenty three patients with severe CAD who were scheduled to coronary artery by-pass grafting surgery and 6 patients with angiographycally NCAs were included in the study. Activation of peripheral blood DCs have been analyzed by flow cytometric measures of CD86 activation. RESULTS In patients with CAD and without DM, DC activation significantly increased after stimulation of oxidesized LDL (135 ± 121 vs 248 ± 197 p = 0.024). However this activation didn't significantly increased in patients with CAD and DM (100 ± 20 vs 120 ± 97, p = 0,54). Patients with NCAs and without DM showed marked activation of CD86 after stimulation with ox-LDL. CONCLUSION We have documented that DC activation, upon stimulation of ox-LDL has blunted in patients with CAD compared to patients with NCAs. Moreover this defective activation is more pronounced in those with diabetic patients with CAD.

Abstract
BACKGROUND Liver biopsy is recommended in the majority of patients with chronic viral hepatitis for fibrosis evaluation. Because of the potential risks of liver biopsy, many studies related to non-invasive biomarkers of hepatic fibrosis have been performed. We aimed to assess the diagnostic value of serum biglycan as a non-invasive fibrosis marker in chronic hepatitis B patients. METHODS This study included 120 patients with biopsy-proven hepatitis B patients and 60 healthy controls. Fibrosis stage and necroinflammatory activity were assessed in liver biopsy specimens. Biglycan level was measured using an ELISA assay. RESULTS Serum biglycan levels of chronic hepatitis B patients were found to be significantly higher than those of healthy controls (337.3±363.0 pg/mL vs 189.1±61.9 pg/mL, respectively, P<.001). There was a statistically significant positive correlation between serum biglycan level and fibrosis stage (P=.004; r=.213). Besides, a statistically significant positive correlation was found between serum biglycan level and necroinflammatory activity (P<.001; r=.271). The AUROC of BGN levels was 0.702 for fibrosis stage, differentiating patients from healthy controls with statistical significance (P<.001). The AUROC of BGN levels was 0.632 for necroinflammatory activity score, differentiating patients from healthy controls with statistical significance (P=.004). CONCLUSIONS Serum biglycan might be used as a non-invasive marker of liver fibrosis. Further studies are needed to evaluate the usefulness of this marker.

Abstract
AIM Cognitive dysfunction is a neurologic manifestation in primary Sjögren syndrome (PSS). On the other hand, several antibodies are related to cognitive dysfunction. The aim of this study is to assess the cognitive dysfunction of PSS patients via detailed neurologic tests. Moreover, its associations with antibodies were also evaluated. METHOD Twenty-eight female patients with PSS and 17 healthy controls comprised the study groups. Short-term memory, long-term memory, verbal learning, visual memory, visual spatial perception, attention, verbal frequency function, executive functions and information processing speed were evaluated with neurologic tests in both of the study groups. Furthermore, anti-N-methyl-D-aspartate (NMDA) type anti-glutamate-receptor antibody, anti-ribosomal-p and antiganglioside antibodies were assessed in the study groups. RESULTS The attention, data processing speed, verbal learning, short-term verbal memory and visuo-spatial perception performances were lower in the patients with PSS when compared to the healthy controls. The difference reached statistical significance in Paced Auditory Serial Addition Test (P < 0.01), Serial Digit Learning Test (P < 0.01), clock drawing (P = 0.03), Auditory Verbal Learning Test immediate verbal memory (P = 0.01) and Benton Judgement of Line Orientation Test (P = 0.03). Even if antiganglioside antibodies were more likely to be present in the PSS group when compared to the healthy controls, no relationship was found between its positivity and cognitive dysfunction. CONCLUSION Results of this study suggest that cognitive dysfunction is quite prevalent in PSS patients without being associated with studied antibodies.

Abstract
Exact pathogenesis of Behcet’s Disease (BD) hasn’t been known but recent studies suggest it’s a genetic-based and immune-related disease. We aimed to investigate the association between disease activity and Th1, Th17 and Treg cells in BD patients via IL-17A/F, IL-23, IL-12/23p40, IL-35 produced by these cells. We also compared our findings with those of SLE patients to investigate their specificity for immunopathogenesis of BD. 15 active and 15 inactive BD patients, 12 active and 12 inactive SLE patients and 12 sex & age-matched healthy controls were involved. Peripheral blood lymphocyte cultures were done. Supernatants from PHA-stimulated and -unstimulated cultures were measured for IL-17A/F, IL-12/23p40, IL-23 and IL-35 levels in time-dependent manner (48 and 72 hrs) by ELISA. For disease activity International Study Group Diagnostic Criteria and SLEDAI index were used for BD and SLE, respectively. IL-17 and IL-23 increased parallelly in both BD and SLE; IL-17 was higher but another Treg cytokine IL-35 was lower in active BD and active SLE compared to healthy controls. After 48 and 72 hrs of PHA stimulation the highest levels of IL-17A/F, IL-22723p40 and IL-23 were measured in active BD followed by active SLE. Our data suggest that IL-17, IL-23 and IL-12/23p40; Th17 and Th1 responses play role in pathogenesis of BD. Finding IL-35 to be lower in active BD compared to inactive BD patients and healthy controls made us think that there can be a plasticity between Th17 and Treg cells depending on disease activity. This is the first time such plasticity is suggested for BD in literature. Our findings also show that IL-17/23 axis contributes to pathogenesis of SLE (another inflammatory rheumatic disease) in addition to other mechanisms like in BD.

Abstract
OBJECTIVE To evaluate the influence of posterior subtenon injection of 40 mg of triamcinolone acetonide (TA) on blood glucose, cortisol and adrenocorticotrophic hormone (ACTH) in patients with clinically significant diabetic macular oedema. PATIENTS AND METHODS This prospective clinical study included 33 type 2 diabetic patients assigned to receive subtenon injection of 40 mg of TA (study group: 20 patients, 9 women and 11 men, mean age 60.8 ± 10.1 years) or subtenon injection of 1 ml of saline solution (control group: 13 patients, 7 women and 6 men, mean age 57.9 ± 7.5 years) as an adjunct to focal/grid laser therapy. Pre-injection laboratory tests consisted of fasting blood glucose (FBG), glicolised hemoglobin (HbA1c), fructosamine, ACTH and cortisol. Post-injection measurements were performed in a following schedule: FBG in day 1; FBG, ACTH and cortisol at week 1; FBG, fructosamine, ACTH and cortisol at month 1, 2 and 3. HbA1c was also measured at 3 months. The mean ± SD values of groups at each visit were compared. The time-related changes in the parameters in each group were also analyzed using SPSS (Statistical Package for Social Sciences) for Windows 15.0 software. RESULTS Pre-injection FBG, HbA1c, fructosamine, ACTH and cortisol were similar in both groups (p > 0.05 for all). Pre-injection and final HbA1c values were similar in the study (8.6% ± 1.9 and 8.7% ± 1.8, respectively) and control groups (8.6% ± 1.7 and 8.5% ± 1.8, respectively) (p > 0.05 for all). None of the patients had a decrease in plasma cortisol that decreased below normal values at either time point. There was no statistically significant difference between groups and between each visit in groups according to FBG levels, blood fructosamine, ACTH and cortisol levels (p > 0.05 for all). No adverse event was observed. CONCLUSIONS Subtenon injection of 40 mg of TA does not increase blood sugar levels significantly, and it does not suppress blood cortisol or ACTH levels at 1 week or later in patients with diabetes mellitus. Subtenon injection of 40 mg TA seems to be safe in respect to elevation of blood sugar levels or systemic corticosteroid pathways.
