The predictive value of systemic immune-inflammation index for long-term cardiovascular mortality in non-ST segment elevation myocardial infarction.

BACKGROUND: Increased levels of inflammatory markers have been found in association with the severity of coronary atherosclerosis. Systemic immuneinflammation index (SII), which is calculated by multiplying neutrophil and platelet counts and then dividing the result by the lymphocyte count, can also be used as a prognostic indicator in different cardiovascular diseases. In this study, we investigated SII levels and long-term mortality of patients with non-ST segment elevation myocardial infarction (NSTEMI). METHODS: This is an observational, single-center study. Two hundred-eight patients who underwent coronary angiography for NSTEMI were included in the study. Patients were divided into 3 tertiles based on SII levels. We researched the relationship between level level and 1, 3 and 5 years mortality (NSTEMI). RESULTS: One-year mortality of the patients was significantly higher among patients in the upper SII tertile when compared with the lower and middle SII tertile groups [11 (15.9%) vs. 2 (2.9%) and 6 (8.7%); P  = 0.008, P  = 0.195, respectively). Three-year mortality of the patients was significantly higher among patients in the upper SII tertile when compared with the lower and middle SII tertile groups [21 (30.4%) vs. 5 (7.1%) and 12 (17.4%); P  < 0.001, P  = 0.072, respectively). Five-year mortality of the patients was significantly higher among patients in the upper SII tertile when compared with the lower and middle SII tertile groups [26 (37.7%) vs. 8 (11.4%) and 15 (21.7%); P  < 0.001, P  = 0.040, respectively). CONCLUSION: Our study showed that NSTEMI patients with higher SII had worse long-term mortality.

Incestuous childhood sexual abuse between siblings resulting in pregnancy without sexual intercourse.

Victims of incest are usually women and children who are mostly girls. The abuse between siblings may remain hidden because of the family's fear of social stigma, though it may result in pregnancy. This article presents a case of incestuous childhood sexual abuse between siblings resulting in pregnancy without intercourse, an event rarely reported in the literature. An 11-year-old girl was brought to the hospital because of a stomachache and was detected pregnancy from examinations. Forensic medicine experts determined that the girl's hymen was still intact and non-elastic in the genital examination. Gynecology and Obstetrics Department confirmed the pregnant compatibility with 14 weeks, 4 days; after ultrasonographic monitoring. She was abused by her 14-year-old brother by rubbing for 1 year and this resulted in pregnancy. During the psychiatric examination, her attitude was negative and symptoms of post-traumatic stress disorder emerged. Medical abortion was applied after psychiatric and gynecological examinations. The girl's brother was confirmed as the biological father after the DNA paternity test was conducted on the fetus. Based on this case, this article aimed to examine the medical, social, and legal problems caused by incestuous childhood sexual abuse and contribute to the literature by emphasizing what forensic medicine and preventive medicine approaches should consider in such cases.

Conclusões Até onde se sabe, este é o único estudo que avaliou a homeostase tiol/dissulfeto como um preditor inédito, que está relacionado de forma mais próxima à DVMR e à gravidade da EMi.

Abstract Background Rheumatic mitral valve disease (RMVD) is the most common presentation of rheumatic heart disease (RHD). Inflammation and fibrosis processes also play significant roles in its pathogenesis. Recent studies showed that thiols and thiol-disulfide are promising novel oxidative stress markers. Objectives The present study aimed to evaluate differences in the serum thiol and thiol-disulfide levels in patients with RMVD and the control group. Methods Ninety-two patients with RMVD were enrolled in the study. Fifty-four healthy subjects, age, and gender-matched with the study group, were also included in the study as a control group. This study investigated thiol levels in patients with RMVD and the control group. P-values lower than 0.05 were considered statistically significant. Results The patients with RMVD presented higher systolic pulmonary artery pressure (SPAP) and left atrial (LA) diameter levels than the control group. Native thiol (407±83 μmol/L vs. 297±65 μmol/L, p<0.001) and total thiol (442±82 μmol/L vs. 329±65 μmol/L, p<0.001) levels were higher in the control group. Disulfide (16.7±4.9 μmol/L vs. 14.8±3.7 μmol/L, p=0.011) levels were higher in the group of patients with RMVD. A positive correlation was found between disulfide/native and disulfide/total thiols ratio with SPAP, LA diameter, and MS severity. Disulfide/total thiols ratio was significantly higher in patients with severe MS than with mild to moderate MS patients. Conclusions To the best of our knowledge, this is the only study of its kind that has evaluated thiol/disulfide homeostasis as a novel predictor, which was more closely related to RMVD and the severity of MS.

Retrospective Analysis of Sudden Cardiac Deaths in a 10-Year Autopsy Series in the City of Isparta in Turkey.

Sudden cardiac death (SCD) is an important public health problem that accounts for approximately 15% to 20% of global deaths. Our retrospective study aimed to analyze etiological distribution and epidemiological data of 128 cases with SCD as death cause based on autopsies between 2010 and 2019. The mean age of SCD cases was 57.09, with the highest incidence in older than 60 years (43.8%). Male/female ratio was 4.5:1, peaking with 9.2:1 in the 41- to 60-year age group. Deaths occurred mostly at home (41.4%). Coronary atherosclerotic heart disease (CAD) was main SCD cause (65.6%) with cardiac tamponade (10.9%), unexplained SCD (8.6%), and hypertrophic cardiomyopathy (7.8%) after it. A total of 71.2% of CAD cases had coronary artery stenosis of greater than 75% and 92.9% had atherosclerotic degeneration in the left anterior descending artery. Based on the body mass index-based normal heart weights table, 91.7% of CAD cases had cardiomegaly. This study showed CAD, cardiomegaly, and high body mass index concurrence as a very important SCD risk. Because SCD incidence increases in older than 40 years, determining risk groups through regular medical examinations and inspections, older than 30 years would provide implementation of preventive measures. Some cardiac diseases causing sudden death are undetectable despite detailed autopsy and histopathological examinations. Including postmortem cardiogenetic analysis among routine techniques in sudden deaths would lower sudden unexplained death diagnosis rates.

Platelet-to-lymphocyte ratio is a predictor of long-term mortality in patients with acute coronary syndrome.

INTRODUCTION: Atherosclerosis is a chronic inflammatory process and inflammation is an important component of acute coronary syndrome (ACS). Platelet-to-lymphocyte ratio (PLR) is a useful parameter showing the degree of the inflammatory response. AIM: To explore the association between PLR and long-term mortality in patients with ACS. MATERIAL AND METHODS: A total of 538 patients who had a diagnosis of ACS between January 2012 and August 2013 were followed up to 60 months. On admission, blood sampling to calculate PLR and detailed clinical data were obtained. RESULTS: In total, 538 patients with a mean age of 61.5 ±13.1 years (69% male) were enrolled in the study. Median follow-up was 79 months (IQR: 74-83 months). Patients were divided into 3 tertiles based on PLR levels. Five-year mortality of the patients was significantly higher among patients in the upper PLR tertile when compared with the lower and middle PLR tertile groups (55 (30.7%) vs. 27 (15.0%) and 34 (19.0%); p < 0.001, p = 0.010 respectively). In the Cox regression analysis, a high level of PLR was an independent predictor of 5-year mortality (OR = 1.005, 95% CI: 1.001-1.008, p = 0.004). Kaplan-Meier analysis according to the long-term mortality-free survival revealed the higher occurrence of mortality in the third PLR tertile group compared to the first (p < 0.001) and second tertiles (p = 0.009). CONCLUSIONS: PLR, which is an easily calculated and universally available marker, may be useful in long-term risk classification of patients presenting with ACS.

Physicochemical and morphological characterization of atmospheric coarse particles by SEM/EDS in new urban central districts of a megacity.

Physicochemical and morphological characteristics of atmospheric particles in new urban centers of fast-developing megacities are not well understood. In this study, atmospheric coarse particles (PM2.5-10) were simultaneously collected in multiple stations (10) in new urban centers, namely Beylikduzu, Buyukcekmece, and Esenyurt, of Istanbul using a modified passive particulate sampling method. Scanning electron microscope and energy dispersive X-photon spectroscopy (SEM-EDS) was used to investigate the size distribution characteristics, chemical composition and their weight percent abundances, and morphological properties of the collected particles. The particle clusters were mainly dominated by Ca-rich Al silicates, Ca dominant, Ca- and S-rich, and NaCl particles, respectively. Their potential sources were assigned to the natural sources (e.g., wind erosion, soil resuspension, and sea sprays) and anthropogenic activities (construction, transportation, mining and crushing, and cement production). In addition to the major contributions (up to 47% of particle number abundance), the minor contribution clusters (less than 1%) with transitional metals rich particles (Fe, Zn, and Cu rich) mainly from anthropogenic sources (combustion, traffic, and vehicular emissions) were identified. The typical size range (> 0.65 to < 11.00 µm) distribution of the major particle clusters fits a left-skewed modal distribution with a peak at 1.10-2.30-µm size range. However, the number of particles decreases significantly with increasing distance to the source, and this justification is stronger for larger size fractions (> 2.3 µm). Particle numbers and varieties indicated significant spatial variations depending upon the identified sources, meteorological factors, and temporal conditions. In general, the results of this study suggest that the passive sampling of PM2.5-10 coupled with SEM/EDS based single-particle analysis is an effective tool to understand the physicochemical characterization and spatial and temporal variations of atmospheric particles in urban environments.

Can hemodialysis change QRS axis in patients without cardiovascular disease?

OBJECTIVE: Due to rapid changes in volume and electrolyte concentration during hemodialysis (HD), some electrocardiographic (ECG) changes or arrhythmias can be seen. The aim of this study was to assess ECG QRS axis changes and other ECG parameters after HD in patients with end-stage renal disease (ESRD). METHODS: A total of 46 patients (65% male, mean age 52±15 years) with a sinus rhythm and without cardiovascular disease who were undergoing chronic HD treatment were included to the study. Blood samples, 12-lead electrocardiograms, and echocardiograms were recorded immediately before and at the end of an HD session. The QRS axis and other electrocardiographic, echocardiographic, electrolyte parameter, and volume changes were analyzed. RESULTS: The serum urea, creatinine, potassium, and B-type natriuretic peptide concentrations significantly decreased after HD, and the serum calcium levels significantly increased after HD. Body weight significantly decreased after HD. There was no significant difference in the QRS duration, PR interval, P-wave axis, QRS axis, or QT and QTc interval following HD. Based on a comparison of variables according to the any QRS axis change after HD treatment, there was no significant difference in biochemical values, HD time, ultrafiltration volume, left ventricular ejection fraction, or other echocardiographic findings. CONCLUSION: ESRD and HD are complex and dynamic processes, and the change in the QRS axis is rarely emphasized in these patients. In our study, there was no significant change in the QRS axis with HD in patients without cardiovascular disease.

Determination of Ethanol in Blood Samples Using Partial Least Square Regression Applied to Surface Enhanced Raman Spectroscopy.

Alcohol consumption triggers toxic effect to organs and tissues in the human body. The risks are essentially thought to be related to ethanol content in alcoholic beverages. The identification of ethanol in blood samples requires rapid, minimal sample handling, and non-destructive analysis, such as Raman Spectroscopy. This study aims to apply Raman Spectroscopy for identification of ethanol in blood samples. Silver nanoparticles were synthesized to obtain Surface Enhanced Raman Spectroscopy (SERS) spectra of blood samples. The SERS spectra were used for Partial Least Square (PLS) for determining ethanol quantitatively. To apply PLS method, 920~820 cm-1 band interval was chosen and the spectral changes of the observed concentrations statistically associated with each other. The blood samples were examined according to this model and the quantity of ethanol was determined as that: first a calibration method was established. A strong relationship was observed between known concentration values and the values obtained by PLS method (R2 = 1). Second instead of then, quantities of ethanol in 40 blood samples were predicted according to the calibration method. Quantitative analysis of the ethanol in the blood was done by analyzing the data obtained by Raman spectroscopy and the PLS method.

Combination of change in hematological parameters with exercise stress test to predict coronary artery disease.

OBJECTIVE: Treadmill exercise stress testing for identifying patients with a higher likelihood of coronary artery disease (CAD) before elective coronary angiography is recommended in the current guidelines. In this study, we aimed to evaluate the changes in the hematological parameters before and after exercise stress test in relation with the presence of CAD. METHODS: A total of 113 patients with chest pain who underwent treadmill exercise testing and coronary angiography were included in this study. RESULTS: Neutrophil count (4.38±0.99 vs 5.19±0.93, P<.001), and neutrophil to lymphocyte ratio (NLR) (2.04±0.63 vs 2.41±0.78, P<.001) were significantly elevated after treadmill exercise test in all the patients. Increase in the NLR after exercise test was significantly higher in patients with positive exercise test (n=68) than negative exercise test (n=45) (0.49±0.58 vs 0.19±0.44, P=.016). The sensitivity and specificity of treadmill exercise testing according to coronary angiography was 79% and 64%, respectively. A cut-off point of 0.2 for the change in the NLR in addition to positive treadmill exercise testing had 91% sensitivity and 92% specificity in predicting significant coronary artery stenosis (AUC:0.913, 95% CI: 0.805-1.000, P<.001). CONCLUSIONS: Neutrophil to lymphocyte ratio is an important inflammatory marker that can contribute to treadmill ECG testing in predicting CAD.

The relationship between fragmented QRS and functional significance of coronary lesions.

BACKGROUND: Recently fragmented QRS (fQRS) on electrocardiography (ECG) has been introduced as a predictor of myocardial scarring and myocardial ischemia in coronary artery disease (CAD). OBJECTIVE: The aim of this study was to investigate the relationship between fQRS and fractional flow reserve (FFR) results in patients with the intermediate degree of coronary artery stenosis. METHODS: A total of 301 consecutive patients who underwent coronary angiography (CAG) and FFR measurement for intermediate coronary artery stenosis were included in the study. The study patients were divided into two groups: the low FFR group (FFR value of ≤0.80) and normal FFR (FFR value of >0.80) group. Both groups were compared in terms of the presence of fQRS. RESULTS: Of 301 patients, fQRS was detected in 128 (42.5%) and low FFR was detected in 115 (38.2%). In the low FFR group, fQRS was significantly higher (P<0.001). Multivariate analysis showed that fQRS was an independent predictor of myocardial ischemia in patients with intermediate coronary stenosis (OR=7.202, CI 95%, 4.195-12.367; p<0.001). The presence of fQRS had 70% sensitivity and 74% specificity for the prediction of FFR≤0.80. CONCLUSION: In clinical practice, the presence of fQRS on ECG is associated with myocardial ischemia in patients with intermediate coronary stenosis.

Assessment of serum asymmetric dimethylarginine levels and left ventricular diastolic function in patients with ankylosing spondylitis.

AIM: To assess left ventricular diastolic functions and serum dimethylarginine (ADMA) concentrations, as well as the effect of different treatment strategies on ADMA concentrations and diastolic function parameters, in patients with ankylosing spondylitis (AS). METHOD: Sixty AS patients and 40 control subjects without classical cardiovascular (CV) risk factors were included in the study. Baseline clinical and echocardiographic variables were obtained. C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and ADMA levels were measured. Spinal mobility, disease activity and functional status were assessed using Bath Ankylosing Spondylitis Metrology Index, Bath Ankylosing Spondylitis Disease Activity Index and Bath Ankylosing Spondylitis Functional Index. RESULTS: CRP, ESR and ADMA levels were significantly higher in the AS group as compared to the control group. Two (5%) control subjects and six (10%) AS patients met the criteria for left ventricular diastolic dysfunction (DD) on conventional Doppler echocardiography, but the difference was not statistically significant (P = 0.36). However, using tissue Doppler imaging, 12 (20%) patients in the AS group and three (8%) subjects in the control group were diagnosed with left ventricular DD (P = 0.08). The anti-tumor necrosis factor (TNF)-α group, conventional therapy group and control group were compared in terms of ADMA, CRP, ESR levels and echocardiographic parameters. ADMA levels were significantly lower in anti-TNF-α group as compared to the conventional therapy group (P < 0.001). In the control group, ADMA levels were significantly lower than both treatment groups (P < 0.001). CONCLUSION: Increased ADMA levels reveal impaired nitric oxide metabolism in a relatively young group of patients with AS, who have no classical CV risk factors. Anti-TNF-α may have beneficial effect on endothelial function in AS patients by reducing ADMA levels.

The utility of the TIMI risk index on admission for predicting angiographic no-reflow after primary percutaneous coronary intervention in patients with STEMI.

BACKGROUND/AIM: The thrombolysis in myocardial infarction (TIMI) risk score (TRS), and the TIMI risk index (TRI) have been reported in coronary artery disease patients. We investigated whether admission TRI is associated with no-reflow (NRF) in patients undergoing primary percutaneous coronary intervention (p-PCI). MATERIALS AND METHODS: ST-segment elevation myocardial infarction (STEMI) patients treated with p-PCI were included in the study. TRI was calculated on admission using specified variables. We defined the angiographic NRF phenomenon as a coronary TIMI flow grade of ≤2 after the vessel was recanalized or a TIMI flow grade of 3 together with a final myocardial blush grade (MBG) of <2 in a manner as described in previous studies. RESULTS: A total of 371 patients (aged 62 ± 14 years; 73/27 men to women ratio) who underwent p-PCI were enrolled in the study. In terms of age, NRF patients were older than reflow patients (P < 0.017 for MBG). Killip class III-IV designations were more common in NRF patients (P = 0.029 for MBG). TRI (P = 0.014 for MBG) values were significantly greater in the NRF group. TRI was an independent predictor of NRF according to MBG flow (P = 0.003, B = -0.035, Exp B = 0966, 95% CI, 0.944-0.988). CONCLUSION: Admission TRI may predict the development of NRF phenomenon after p-PCI in patients with acute STEMI.

Association between central aortic pulsatility and glomerular filtration rate in patients with coronary artery disease.

OBJECTIVE: Aortic stiffness and chronic kidney disease share common risk factors. Increased aortic stiffness is a predictor of lower estimated glomerular filtration rate (eGFR) at lower levels of renal functions. We aimed to investigate the association between invasively measured central aortic pulsatility (AP) as an indicator of aortic stiffness and eGFR in a population with coronary artery disease and without overt renal disease. METHODS: This study had a cross-sectional design. Data were retrospectively collected. We evaluated 72 patients (44 males and 28 females; mean age 59.0±10.3 years) with coronary artery disease. eGFR was calculated with dividing the Cockcroft-Gault formula by body surface area. Direct measurements of aortic blood pressures were utilized to calculate pulse pressure and AP. Multiple linear regression analysis was performed to test the relationship between eGFR and AP, independent from potential confounders. RESULTS: eGFR was significantly correlated with age (r=0.489, p<0.001), body surface area (r=0.324, p=0.006), weight (r=0.323, p=0.006), aortic pulse pressure (r=-0.371, p=0.001), and AP (r=-0.469, p<0.001). In multiple linear regression analysis, AP was independently associated with eGFR (p=0.035), beside the age and body surface area. An AP cut-off level of >0.71 had 84% sensitivity and 72% specificity in predicting eGFR of <90 mL/min per 1.72 m2 (receiver-operating characteristic area under curve: 0.851, 95% CI: 0.760-0.942, p<0.001). CONCLUSION: We found an independent relationship between invasively measured AP and eGFR in patients with coronary artery disease. Moreover, a higher AP may predict lower eGFR. These results may be utilized to predict eGFR from AP during invasive procedures.

Peripartum cardiomyopathy in Turkey: Experience of three tertiary centres.

We conducted this study to determine demographic details, and clinical presentations in patients with peripartum cardiomyopathy (PPCMP) of Turkish origin. The study population consisted of 58 patients with PPCMP treated at 3 major hospitals in Turkey, retrospectively. In this study, demographic details and initial echocardiographic data were recorded and long-term clinical status was evaluated. The mean age for the patient cohort was 31.47 ± 6.31 years. Thirty-eight patients (73.1%) were multigravida and seven patients had multifetal pregnancy (13.7%). The mean follow-up left ventricular (LV) ejection fraction increased from 31 ± 7 to 38 ± 19. A minority of patients were defined as improvers according to our pre-specified criteria. The average survival period after diagnosis of PPCMP was 20.66 ± 14.44 months. Initial values for LV end-diastolic diameter and urea were higher in the deceased patients compared with the surviving patients, respectively. Twenty-eight (48%) patients with PPCMP showed improvement in the follow-up period. Of the 58 PPCMP patients, 9 (15%) died during a mean follow-up of 32 ± 22 months.

Clinical and angiographic outcomes at more than 1 year after treatment of chronic total occlusions with the everolimus-eluting bioresorbable vascular scaffold.

OBJECTIVE: Treatment of chronic total occlusion (CTO) with everolimus-eluting bioresorbable vascular scaffold (BVS) is safe and effective at short-term follow-up (FU). The current study investigated clinical and angiographic outcomes after treatment of CTO with BVS at >1 year. METHODS: Thirty patients who underwent successful recanalization of 35 CTOs were included in this study. Quantitative coronary angiography (QCA) was performed at median FU period of 402 days. Clinical endpoints analyzed included all-cause mortality, cardiac death, non-fatal target vessel myocardial infarction, target vessel revascularization (TVR), symptom-driven target lesion revascularization (TLR), and BVS thrombosis. RESULTS: QCA analysis revealed in-scaffold minimal luminal diameter of 2.14±0.50 mm and late lumen loss (LLL) of 0.38±0.54 mm. One cardiac death, 5 cases with TVR, and 3 cases with TLR were detected at median FU time of 542 days. No BVS thrombosis was observed. CONCLUSION: The Absorb BVS was safe and effective in the treatment of CTO with acceptable LLL at mid-term FU, comparable to drug eluting stents.

Clinical Characteristics and Outcome of Cardiovascular Implantable Electronic Device Infections in Turkey.

Infection is one of the most devastating outcomes of cardiovascular implantable electronic device (CIED) implantation and is related to significant morbidity and mortality. In our country, there is no evaluation about CIED infection. Therefore, our aim was to investigate clinical characteristics and outcome of patients who had infection related to CIED implantation or replacement. The study included 144 consecutive patients with CIED infection treated at 11 major hospitals in Turkey from 2005 to 2014 retrospectively. We analyzed the medical files of all patients hospitalized with the diagnosis of CIED infection. Inclusion criteria were definite infection related to CIED implantation, replacement, or revision. Generator pocket infection, with or without bacteremia, was the most common clinical presentation, followed by CIED-related endocarditis. Coagulase-negative staphylococci and Staphylococcus aureus were the leading causative agents of CIED infection. Multivariate analysis showed that infective endocarditis and ejection fraction were the strongest predictors of in-hospital mortality.

Relationship Between Hematologic Indices and Global Registry of Acute Coronary Events Risk Score in Patients With ST-Segment Elevation Myocardial Infarction.

The aim of this study was to evaluate the relationship between hematologic indices and the Global Registry of Acute Coronary Events (GRACE) score in patients with ST-segment elevation myocardial infarction (STEMI). A total of 800 patients who consecutively and retrospectively presented with STEMI within 12 hours of symptom onset. After accounting for exclusion criteria, a total of 379 patients remained in the study. We enrolled 379 patients with STEMI (mean age 61.7 ± 13.6 years; men 73%). Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), red cell distribution width (RDW), and monocyte count were associated with increased worse GRACE risk score (P = .008, P = .012, P = .005, P = .022, respectively). In multivariate linear regression analysis, NLR, PLR, RDW, and monocyte count were found to be independent predictors of GRACE risk score. We demonstrate for the first time that PLR, RDW, and monocyte were associated with the GRACE score in patients with STEMI.

Novel markers of endothelial dysfunction and inflammation in Behçet's disease patients with ocular involvement: epicardial fat thickness, carotid intima media thickness, serum ADMA level, and neutrophil-to-lymphocyte ratio.

The etiology of Behçet's disease (BD) has not been fully elucidated. However, immunological and environmental factors, endothelial dysfunction (ED), and genetic susceptibility have been proposed to play a role. In this study, we aimed to evaluate epicardial fat thickness (EFT) together with serum asymmetric dimethylarginine (ADMA), carotid intima media thickness (CIMT), and neutrophil-to-lymphocyte ratio (NLR) in BD patients with ocular involvement. Thirty-six ocular BD patients (17 active and 19 inactive ocular involvement), and 35 age and sex-matched healthy controls were enrolled to this cross-sectional study. All patients underwent examinations with transthoracic echocardiography and carotid Doppler ultrasound. Serum ADMA levels, CIMT, EFT, and NLR were compared between groups, and their association with disease activity was evaluated. Behçet's disease patients had higher WBC counts, neutrophil counts, NLR, CIMT, EFT values, and serum ADMA levels than do healthy controls. The other biochemical, hematological, and echocardiographic parameters were comparable between the two groups. Behçet's disease duration was positively correlated with EFT and CIMT. Multivariate logistic regression analysis revealed that increased serum ADMA concentration and CIMT are independently associated with BD. Neutrophil counts, NLR, and serum ADMA level were higher, and lymphocyte count was lower in patients with active ocular BD compared to those of inactive ocular BD group. Carotid intima media thickness, serum ADMA level, EFT, and NLR were increased in ocular BD patients compared to healthy subjects. In addition, both serum ADMA level and NLR were associated with disease activity of ocular involvement. Increase in disease duration was associated with increase in CIMT and EFT which suggests that anatomical changes occur in time during the disease course. Increased CIMT, serum ADMA level, EFT, and NLR may provide new clues about the role of ED and inflammation in the etiopathogenesis of BD.
