Regular coffee intake improves liver enzyme levels and liver histology in patients with chronic alcohol consumption, non-alcoholic fatty liver and non-alcoholic steatohepatitis: Report of 259 cases.

Background and Aim: This study aims to investigate the effects of chronic coffee consumption (>5 years) and type of coffee in non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver (NAFLD) and patients who have regular alcohol consumption. Materials and Methods: In this study, 158 healthy individuals and 101 patients with histologically proven NASH were enrolled. The daily amount of coffee intake, amount of alcohol use and type of coffee were calculated for all patients. The degree of steatosis and fibrosis was analyzed by transient elastography and liver ultrasound in non-NASH and by liver biopsy in NASH patients. Results: Patients with a history of coffee consumption (n=132) had lower liver enzyme levels compared to the non-coffee group (n=127) (p=0.001). Serum ALT level was significantly lower [ALT: 21.2±11.7 U/L vs. 56.4±15.6 U/L (p=0.004)], and the liver histopathology was significantly better for patients with a coffee consumption of daily for >5years (p=0.045 for fibrosis score for NASH, p=0.036 for LSM and p=0.015 for CAP measurements for the non-NASH patient). Conclusion: Coffee seems to have a positive protective effect on liver histology and liver enzyme levels in healthy individuals, in patients with chronic alcohol consumption, NAFLD and NASH. These results are more prominent in patients who drink coffee on a regular daily base for more than five years.

Aortic flow propagation velocity, epicardial fat thickness, and osteoprotegerin level to predict subclinical atherosclerosis in patients with nonalcoholic fatty liver disease.

OBJECTIVE: Nonalcoholic fatty liver disease is the most common cause of liver dysfunction in Western countries and an independent risk factor for atherosclerotic heart disease. Appropriate noninvasive parameters are lacking for optimal risk stratification of cardiovascular disease in these patients. We evaluated several recently discovered noninvasive parameters for atherosclerosis in patients with nonalcoholic fatty liver disease: epicardial fat thickness, aortic flow propagation velocity, and osteoprotegerin level. METHODS: Forty-one patients (27 men and 14 women; mean age, 37.9±8.9 years) with nonalcoholic fatty liver disease and 37 control subjects (17 men and 20 women; mean age, 34.5±8.6 years) were enrolled in this observational case-control study. Patients with nonalcoholic fatty liver disease diagnosed at a gastroenterology outpatient clinic were included. Patients with cardiac pathology other than hypertension were excluded. Epicardial fat thickness and aortic flow propagation velocity were measured by echocardiography. The serum concentration of osteoprotegerin was measured using a commercial enzyme-linked immunosorbent assay kit. RESULTS: Nonalcoholic fatty liver disease patients exhibited a significantly lower aortic flow propagation velocity (155.17±30.00 vs. 179.00±18.14 cm/s, p=0.000) and significantly higher epicardial fat thickness (0.51±0.25 vs. 0.29±0.09 cm, p=0.000) than control subjects. Osteoprotegerin levels were higher, but not significant, in patients with nonalcoholic fatty liver disease (28.0±13.0 vs. 25.2±10.8 pg/mL, p=0.244). Binary logistic regression analysis showed that aortic flow propagation velocity (OR, -0.973; 95% CI, 0.947-0.999) and waist circumference (OR, -1.191; 95% CI, 1.088-1.303) were independent predictors of nonalcoholic fatty liver disease. CONCLUSION: In this study, epicardial fat thickness and osteoprotegerin level were higher and aortic flow propagation velocity was lower in patients with nonalcoholic fatty liver disease. Early detection of abnormal epicardial fat thickness and aortic flow propagation velocity may warrant a search for undetected cardiovascular disease in patients with nonalcoholic fatty liver disease.

Ongoing symptoms after eradication of Helicobacter pylori: psychiatric disorders may accompany.

BACKGROUND/AIMS: The precise mechanism of functional dyspepsia is yet to be elucidated. Helicobacter pylori infection and psychiatric disorders are implicated in the etiology. We aimed to determine the prevalence of psychiatric co-morbid disorders in patients with Helicobacter pylori-positive functional dyspepsia and the impact of existing psychiatric disorders on symptomatic response following eradication treatment. MATERIAL AND METHODS: Patients with Helicobacter pylori-positive functional dyspepsia and no previous diagnosis of any psychiatric disorder were included in the study. All patients' symptoms were evaluated with a visual analog scale and Likert scale. The Composite International Diagnostic Interview was applied to all patients by an experienced psychiatric nurse. RESULTS: At least one psychiatric disorder was diagnosed in 22 of 54 patients. The most common disorder was depression, found in 13 patients. Symptomatic response to treatment was significantly higher in functional dyspepsia patients with no psychiatric disorder compared to those with at least one psychiatric co-morbid disorder (84% vs. 50%; p=0.007). CONCLUSION: Psychiatric co-morbid disorders are common in patients with functional dyspepsia and affect symptomatic response to Helicobacter pylori eradication treatment. Psychiatric disorders should be considered in patients who fail to achieve sufficient symptomatic relief after Helicobacter pylori eradication treatment.

Lack of relationships between FGF19 staining pattern, lymph node metastasis and locally invasive characteristics of the tumor in colorectal cancers.

INTRODUCTION: Colorectal cancers are in the top of the cancer-related causes of death in the world and lymph node metastasis is accepted as the primary prognostic factor. In this study, correlations of FGF19 staining pattern with local invasion and lymph node metastasis in a series of colorectal cancers were investigated. METHODS: This studyincluded 81 colorectal cancer patients who underwent surgery in our hospital with no evidence of preoperative radiological distant metastasis. Routine pathological examination of the resection material was performed in order to identify vascular, perineural and serosal infiltration, regional lymph node metastasis and the degree of differentiation. Tumor tissue samples were stained with an immunohistochemistry method for FGF 19 evaluation and the staining pattern was statistically compared with the above mentioned characteristics of the tumors. RESULTS: The patient population consisted of 47 females and 34 males with a median age of 70 years. In 40 patients regional lymph nodes were positive and 51%, 32% and 38% had serosal, perineural and vascular invasion. While 64 cases were moderately-differentiated, 11 cases were well-differentiated and 6 poorly- differentiated, there was no association with FGF 19 staining, including intensity. CONCLUSION: No evidence of significant statistically correlation was found between FGF 19 staining pattern and serosal, perineural, vascular invasion, lymph node involvement and degree of differentiation.
