Background/aims: Inflammatory bowel diseases (IBD) impairs patients' quality of life (QoL). Inflammatory bowel disease questionnaire (IBDQ) is created to measure the health-related QoL specific for IBD. We planned to investigate the validation and reliability of the Turkish translation of IBDQ., Materials and Methods: Patients filled self-report questionnaires (Turkish Inflammatory bowel disease questionnaire (TrIBDQ) and Short Form-36 (SF-36)) themselves under a physician's supervision, and they were free to ask questions about the questionnaires. The participants then filled the same questionnaire after at least two weeks. Construct validity, discriminant ability, reliability, and susceptibility to change were analyzed separately for the IBD patients. Intra-class correlation coefficient (ICC) was used to assess test-retest reliability. Cronbach's alpha values were used to assess internal consistency., Results: A hundred patients enrolled in the study, 53 with Crohn's disease (CD), 47 with ulcerative colitis (UC). We found a moderate to high positive correlation between the TrIBDQ domains and the SF-36 dimensions. In UC and CD, TrIBDQ was able to differentiate active disease and remission. We found Cronbach's alpha for TrIBDQ domains ranged from 0.76-0.94 in CD and from 0.79-0.92 in UC. The total Cronbach's alpha for TrIBDQ was 0.96 in CD and 0.95 in UC. Sensitivity-to-change analyses of the bowel, systemic, and emotional scores showed statistically significant differences between their baseline and follow-up values., Conclusion: TrIBDQ is a valid and reliable tool for assessing the quality of life in Turkish speaking IBD patients. Thus it can be used in clinical research and practice.

Background/aims: Nonalcoholic fatty liver disease (NAFLD), which consists of nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH), is a growing epidemic in Turkey, considering the recent alarming prevalence of 48.3%. Patients with NASH and/or liver fibrosis are more likely to progress to advanced liver disease. In this single-center study, we sought to describe the clinical and histological characteristics of a sample of Turkish patients with biopsy-proven NAFLD, who were enrolled over a 4-year period., Materials and Methods: This is a retrospective analysis of prospectively collected data from a total of 468 patients (224 males, 244 females; median age, 47 [18-71]. The study cohort consisted of patients with biopsy-proven NAFLD who were followed up at our outpatient clinic from 2009 to 2010 and from 2017 to 2018. Histological classification of the biopsies was performed according to the Steatosis, Activity and Fibrosis (SAF) scoring allowing the use of Fatty Liver Inhibition of Progression (FLIP) algorithm and the NAFLD Activity Score (NAS) scoring system., Results: Based on the SAF scoring, most patients (90.4%) had biopsy-proven NASH, whereas the NAFL was much rarer (9.6%). The prevalence of significant fibrosis (≥F2), advanced fibrosis (≥F3), and cirrhosis (F=4) was 35.0%, 17.5%, and 3.8%, respectively. The percentage of lean, overweight, and obese patients with NAFLD was 6.4%, 32.6%, and 61%, respectively. Metabolic syndrome was prevalent in 63% of the patients and Type 2 diabetes mellitus in 33.5%., Conclusion: The growing burden of NAFLD as a public health problem in Turkey is underscored by its marked histological severity in terms of NASH and fibrosis. Well-conducted clinical trials will be essential for slowing down the NASH progression.
