    Objectives: There is no reliable and valid biomarker to identify Irritable bowel syndrome (IBS) and its subtypes. The aim of this study is to explore potential serum biomarkers that may be associated with IBS subtypes, particularly in the vitamin D pathway. Methods: The study population comprised 75 IBS patients and 79 controls. Patients divided into IBS subtypes. Routine biochemical parameters, 25-OH-vitamin D, vitamin D binding protein (VDBP) and vitamin D receptor (VDR) serum levels were compared between IBS subtypes and controls. Factors related to IBS subtypes were examined by multivariate logistic regression analysis. Results: Vitamin D levels were lower; VDBP and VDR were higher in all IBS patients than in controls (p<0.001; 0.047 and 0.029, respectively). According to logistic regression analysis, VDBP was a disease-related parameter as much as vitamin D in all IBS subtypes. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were higher especially in diarrhea-dominant IBS (IBS-D) (p=0.041; 0.046) and vitamin B12 were significantly lower in constipation-dominant IBS (IBS-C) (p=0.001). Conclusions: Increased VDBP levels were associated with all IBS subtypes. Patients, especially in IBS-D, had higher serum levels of VDBP, CRP and ESR. Vitamin B12 deficiency, which we consider as a result of the disease, was more common in IBS-C.

    Relationship between appendicitis and diameter of ileocecal lipomatosis and also ileocecal angle
    Börekci, H; Serin, HI; Bas, H; Börekci, E
    Purpose One of the most widespread surgical conditions is acute appendicitis in industrialized countries. Nevertheless, diagnosis of borderline cases is mostly troublesome and needs subsequent researches. For this reason, we aimed to investigate new parameters to improve estimation of acute appendicitis. Lymphoid hyperplasia, impacted stool, faecolith, caecal or appendiceal tumors have been accepted as causes of appendicitis formation, but anatomic variations of diameter of ileocecal lipomatosis and ileocecal angle have been never discussed before. The aim of this study was to assess the relationship between appendicitis and diameter of ileocecal lipomatosis and ileocecal angle. Materials and methods 96 Patients (51 women, 45 men) who were found to have acute appendicitis during exploration and 67 patients (32 women, 35 men) who were not pre-diagnosed with acute appendicitis were enrolled in the study. The diameter of ileocecal lipomatosis and also ileocecal angle values were obtained via computed tomography (CT) scans. Results There were no significant differences between two groups in the mean of ileocecal angle (p > 0.05) but diameter of ileocecal lipomatosis values was significantly higher in the appendicitis-positive group compared with the appendicitis-negative group (p: 0.001). Conclusions There is a relationship between increase in diameter of ileocecal lipomatosis and appendicitis formation.
