Epidemiologic features of inflammatory bowel disease in Western Blacksea region of Turkey for the last 10 years: retrospective cohort study.

BACKGROUND/AIMS: There are only a few epidemiological study about inflammatory bowel disease in the last 10 years in Turkey, especially in Western Blacksea region. In our study, we aimed to identify the changes in the incidence and the prevalence of inflammatory bowel disease in Western Blacksea region at the last 10 years. METHODS: Totally 223 patients with inf lammatory bowel disease (160 ulcerative colitis, 63 Crohn's disease) were enrolled in the study followed up between 2004 to 2013 years. The epidemiological characteristics of patients were recorded. RESULTS: The prevalences were 12.53/105 and 31.83/105 for Crohn's disease and ulcerative colitis respectively. Mean annual incidences increased from 0.99/105 and 0.45/105 for ulcerative colitis and Crohn's disease (2004 to 2005 years) to 4.87/105 and 2.09/105 for ulcerative colitis and Crohn's disease respectively (2011 to 2013 years). While the prevalence was higher in urban areas in Crohn's disease (12.60/105 ), it was higher in rural areas in ulcerative colitis (36.17/105 ). In ulcerative colitis, mean annual incidences were 2.91/105 and 2.86/105 for urban and rural areas respectively. In Crohn's disease, they were 1.37/105 and 1.08/105 for urban and rural areas respectively. CONCLUSION: The incidence of inflammatory bowel disease seems to increase in Western Blacksea region at the last 10 years. This increment is more prevalent in rural areas.

Does neutrophil-to-lymphocyte ratio predict active ulcerative colitis?

BACKGROUND: Inflammatory markers have been studied in ulcerative colitis (UC) for diagnosis, disease activity, and prediction of relapse. Blood neutrophil-to-lymphocyte (N/L) ratio has been used to determine outcomes of some malignancies and coronary artery disease. Blood N/L ratio is a simple sign of clinical inflammation. In this study, we examined N/L ratio in recurrent patients suffering from UC. METHODS: The aim of the present study was to analyze N/L ratios in serum samples of UC patients in remission and active phases. Patients' age, extend of the disease, disease duration, disease activity, drug, and other medical history were all noted for patients. C-reactive protein, erythrocyte sedimentation rate, and complete blood count were determined for patients. RESULTS: Forty-nine UC patients were admitted into the present study. The blood N/L ratios were significantly increased in active phase compared with inactive UC patients (p < 0.05). The cut-off value for N/L ratio for the detection of active UC patients was calculated as ≥ 2.3 using receiver operating characteristic analysis [sensitivity: 61.2 %, specificity: 66.7 %, AUC: 0.650 (0.540-0.760), p = 0.01]. CONCLUSIONS: Present study shows that in patients with UC, the blood N/L ratio is associated with active disease. N/L ratio may be used as an activity parameter in UC.

Chronic hepatitis B associated with hepatic steatosis, insulin resistance, necroinflammation and fibrosis.

BACKGROUND: The effect of hepatitis B virus (HBV) infection on fatty liver disease is unclear. OBJECTIVES: The aim of this study was to investigate the viral and host causes of fatty liver in chronic hepatitis B (CHB) patients. This study included 88 CHB patients of which 17 were not treated. Liver biopsy was performed in each patient. Group 1 included those with hepatic steatosis (n=28) and group 2 those without hepatic steatosis. The groups were compared in terms of age, body mass index (BMI), Homeostasis Model Assessment- Insulin Resistance (HOMA-IR), viral load, biochemical parameters and histological findings. Patients in group 1 were subdivided according to the degree of steatosis as follows: grade 1 (15 patients, 53.6%), grade 2 (6 patients, 21.4%), and grade 3 (7 patients, 25%). RESULTS: In group 1 (n=28), mean age, BMI, cholesterol, and HOMA-IR were found to be significantly higher than in group 2 (n=60). There were no significant differences in the positivity of viral load, HbeAg, treatment, fibrosis and other laboratory parameters between the two groups. HOMA-IR was the only independent predictive factor of liver steatosis in patients with CHB in logistic regression analysis. CONCLUSION: Hepatic steatosis in CHB patients was associated with host metabolic factors.
