    (Verduci Publisher, 2015) Emir, Seyfi; Aydın, M.; Can, G.; Bali, İlhan; Yıldırım, Oğuzhan; Öznur, Meltem; Gürel, A.
    OBJECTIVE: Cancer-related inflammation affects many aspects of malignancy, including proliferation and survival of malignant cells, angiogenesis, and therapeutic response. Some biomarkers representing the degree of systemic inflammation, such as the Glasgow prognostic score, NLR and PLR, have been shown to have prognostic value in many kinds of cancer patients. Aim of this study to investigate to compare neutrophil/leukocyte (NLR) and platelet/lymphocyte (PLR) ratios of the patients with colorectal neoplastic polyps and colorectal cancer (CRC) and tried to determine whether this could be used as a biomarker in follow up of the patients with neoplastic polyps. PATIENTS AND METHODS: A total of 100 colorectal polyps, 113 colorectal cancers and 124 healthy controls were included in the study. Exculusion criteria were endocrinologic or metabolic diseases, acute or chronic diseases, hypertension and atherosclerotic heart diseases, renal diseases. Blood count parameters of the patients were measured. The NLR was calculated as a simple ratio between the absolute neutrophil and the absolute lymphocyte counts. The PLR was defined as the platelet counts to lymphocyte ratio. RESULTS: A statistically significant difference was not detected between Group A and C with regard to NLR and PLR. NLR and PLR were found statistically significantly high in Group B (CRC), Group A (colorectal polyp) and Group C (healthy individuals) (p < 0.001 and p < 0.001). Our study showed that the optimum NLR cutoff point for neoplastic polyps was 2.28 (sensitivity: 68.7%, specificity: 42.3%). When the sensitivity and specificity levels of the PLR were assessed, they were 68.7% and 46.5% for neoplastic polyps, 80% and 68.9% for colorectal cancer. CONCLUSIONS: NLR and PLR may be used for follow up conversion of colonic and rectal neoplastic polyps to invasive tumor.

    Evaluation of epicardial adipose tissue and carotid intima-media thickness as a marker of atherosclerosis in patients with inflammatory bowel disease
    (ARAN Ediciones S.A., 2021) Ekmen, Nergiz; Can, G.; Yozgat, A.; Can, Hamit; Bayraktar, M.F.; Demirkol, MuhammetE.; Sasani, Hadi
    Background and aim: this study aimed to compare carotid intima media (CIMT) and epicardial adipose tissue (EAT) measurements, which are considered as markers for the detection of early atherosclerosis in healthy controls and inflammatory bowel disease (IBD) cases. Methods: a total of 60 IBD patients (25 Crohn’s disease and 35 ulcerative colitis) and 60 healthy patients (as a control group) were included in the study. The measurements of CIMT and EAT were performed using echocardiography and ultrasonography, respectively. Statistical analysis was used to determine the relationship between the parameters. Results: the thickness of bilateral (right and left) CIMT and EAT were significantly higher in IBD than in the control group (p < 0.05). There was a positive correlation between EAT and bilateral (right and left) CIMT in IBD patients (p < 0.05). Conclusion: IBD is associated with an increased thickness of EAT and CIMT. Chronic inflammation in IBD may increase the risk of atherosclerotic heart disease. Thus, only measuring the thickness of EAT and CIMT can be used as an objective, easy, simple, affordable, non-invasive and accessible assessment method in order to screen for this risk. © Copyright 2021.

    Is there any link between atrial arrhythmias and inflammatory bowel disease?
    (Wolters Kluwer Medknow Publications, 2021) Can, G.; Ekmen, Nergiz; Can, Hamit; Bayraktar, M.F.; Demirkol, MuhammetE.; Kayhan, M.A.; Sasani, Hadi
    Background: Inflammation plays an important role in the development of cardiovascular disease, including atherosclerosis and arrhythmia. The aim of this study was to evaluate atrial conduction times (ACTs) in patients with inflammatory bowel disease (IBD) in which systemic chronic inflammation is evident. Methods: In this cross-sectional, prospective, single-center study, 79 IBD patients (51 ulcerative colitis; 28 Crohn's disease) and 70 healthy controls were included. Atrial electromechanical properties were measured by recording simultaneous surface electrocardiography (ECG) with transthoracic echocardiography (ECHO) and tissue Doppler imaging methods. The relationship between age, disease duration, and ACT was evaluated. Results: There were significantly increased conduction durations of lateral-PA (time interval from the onset of the P-wave on surface ECG to the beginning of the late diastolic wave), septal-PA, tricuspid-PA, and interatrial-electromechanical delay (IA-EMD), right intraatrial EMD, and left intraatrial (LI-EMD) durations in IBD patients (P < 0.001). In IBD patients, there was a positive correlation with age, lateral PA, septal PA, tricuspid PA, IA-EMD, and LI-EMD (P < 0.05). A positive correlation was found between disease duration and only lateral PA and tricuspid PA (P < 0.05). Conclusion: In IBD patients, prolonged ACT consists a potential risk for severe atrial arrhythmias. ECG and ECHO screening can be useful in identifying risk groups in IBD patients and taking precautions for future cardiac complications. © 2021 Saudi Journal of Gastroenterology Published by Wolters Kluwer - Medknow.
