The Abdominal Ultrasonography Results of Cappadocia Cohort Study of Turkey Reveals High Prevalence of Fatty Liver.

BACKGROUND: There is limited data about the prevalence of frequent gastrointestinal diseases in developing parts of the world based on community-based screening studies. Therefore, we aimed to present the detailed transabdominal ultrasonography results of the previously completed Turkey Cappadocia cohort study, which included a population-based evaluation of gastrointestinal symptoms and diseases in adults. METHODS: This cross-sectional study was conducted in Cappadocia cohort. The transabdominal ultrasonography, anthropometric measurements, and disease questionnaires were applied to cohort persons. RESULTS: Transabdominal ultrasonography was performed in 2797 subjects (62.3% were female and the mean age was 51 ± 15 years). Among them, 36% were overweight, 42% were obese, and 14% had diabetes mellitus. The most common pathological finding in transabdominal ultrasonography was hepatic steatosis (60.1%). The severity of hepatic steatosis was mild in 53.3%, moderate in 38.8%, and severe in 7.9%. Age, body mass index, liver size, portal vein, splenic vein diameter, hypertension, diabetes mellitus, and hyperlipidemia were significantly higher while physical activities were significantly lower in hepatic steatosis group. Ultrasonographic grade of hepatic steatosis was positively correlated with liver size, portal vein and splenic vein diameter, frequency of diabetes mellitus, hypertension, and coronary artery disease. Hepatic steatosis was observed in none of the underweight, 11.4% of the normal weights, 53.3% of the overweight, and 86.7% of the obese subjects. The percentage of hepatic steatosis cases with normal weight (lean nonalcoholic fatty liver disease) was 3.5%. The rate of lean nonalcoholic fatty liver disease in the entire cohort was 2.1%. Regression analysis revealed male gender (hazard ratio [HR]: 3.2), hypertension (HR: 1.5), and body mass index (body mass index: 25-30 HR: 9.3, body mass index >30 HR: 75.2) as independent risk factors for hepatic steatosis. The second most common ultrasonographic finding was gallbladder stone (7.6%). In the regression analysis, female gender (HR: 1.4), body mass index (body mass index: 25-30 HR: 2.1, body mass index >30 HR: 2.9), aging (30-39 age range HR: 1.5, >70 years HR: 5.8), and hypertension (HR: 1.4) were the most important risk factors for gallbladder stone. CONCLUSIONS: Cappadocia cohort study in Turkey revealed a high prevalence of hepatic steatosis (60.1%) while the prevalence of gallbladder stones was 7.6% among the participants. The results of the Cappadocia cohort located in central Anatolia, where overweight and lack of physical activity are characteristic, showed that Turkey is one of the leading countries in the world for nonalcoholic fatty liver disease.

Continuous insulin therapy versus apheresis in patients with hypertriglyceridemia-associated pancreatitis.

BACKGROUND: The optimal treatment modality for lowering the triglyceride level in patients with hypertriglyceridemia (HTG)-associated acute pancreatitis is unknown. We evaluated the efficacy of continuous insulin infusion and apheresis procedures as triglyceride-lowering therapy. MATERIALS AND METHODS: Clinical, demographic, and laboratory data were retrospectively evaluated for patients with HTG-associated pancreatitis who received continuous insulin infusion or apheresis in a single tertiary center. The endpoints were modality effectiveness and clinical outcomes. RESULTS: The study included 48 patients (mean age, 40.4 ± 9.9 years). Apheresis and insulin infusion were performed in 19 and 29 patients, respectively, in the first 24 h of hospital admission. Apheresis procedures included therapeutic plasma exchange in 10 patients and double filtration plasmapheresis in nine patients. Baseline mean triglyceride level was higher in the apheresis group. The two groups were similar in terms of other baseline clinical and demographic characteristics. Seventeen patients (58.6%) in the insulin group and nine patients (47.4%) in the apheresis group exhibited Balthazar grades D-E. There was a rapid reduction (78.5%) in triglyceride level after the first session of apheresis. Insulin infusion resulted in a 44.4% reduction in mean triglyceride level in the first 24 h. The durations of fasting and hospital stay, and the rates of respiratory failure and hypotension, were similar between groups. More patients in the apheresis group experienced acute renal failure or altered mental status. Prognosis did not significantly differ between groups. CONCLUSION: Although apheresis treatments are safe and effective, they provided no clear benefit over insulin infusion for HTG-associated pancreatitis.

Population-based assessment of gastrointestinal symptoms and diseases: Cappadocia Cohort, Turkey.

BACKGROUND/AIMS: The aim of this study was to determine the prevalence of symptoms and diseases of the lower and upper gastrointestinal system (GIS) in a population-based sample. MATERIALS AND METHODS: The cross-sectional cohort study was conducted in Cappadocia cohort comprising the Gülsehir and Avanos districts. The "Gastrointestinal Symptom Questionnaire" was applied to persons over the age of 18 years. RESULTS: The GI Symptom Questionnaire was applied to 3369 subjects, and height and body weight were measured in 2797 consenting subjects. Of the participants, 61% were female and the mean patient age was 50±15 years. At least one GI symptom was present in 70.6% of the cohort. The most common upper GI symptoms were gastric bloating (31.0%) and heartburn (29.1%). The most common lower GI symptom was abnormal defecation (33.5). The prevalence of upper GIS and lower GIS diseases was 32.7% and 12.9%, respectively, and the prevalence of togetherness of upper and lower GIS diseases was 9.9%. Prevalence of GIS disease was approximately 3 times higher in females (p<0.001). All of the upper and lower GI symptoms and the prevalence of upper GIS disease increased in line with Body mass index (BMI). CONCLUSION: This first population-based, cross-sectional cohort study revealed that the prevalence of GIS diseases is critically high for optimal public health. Special attention must be paid to these diseases while planning health policies and reimbursements.

The relationship between fibrosis and nodule structure and esophageal varices.

BACKGROUND/AIMS: The aim of the present study was to evaluate the histopathological findings of cirrhosis together with clinical and laboratory parameters, and to investigate their relationship with esophageal varices that are portal hypertension findings. MATERIALS AND METHODS: A total of 67 (42 male and 25 female) patients who were diagnosed with cirrhosis were included in the study. The mean age of the patients was 51.6±19.0 (1-81) years. The biopsy specimens of the patients were graded in terms of fibrosis, nodularity, loss of portal area, central venous loss, inflammation, and steatosis. The spleen sizes were graded ultrasonographically, and the esophageal varices were graded endoscopically. RESULTS: In the multivariate regression analysis, there was a correlation between the advanced disease stage (Child-Pugh score odds ratio (OR): 1.47, 95% confidence interval (CI): 1.018-2.121, p=0.040), presence of micronodularity (OR: 0.318, 95% CI: 0.120-0.842, p=0.021), grade of central venous loss (OR: 5.231, 95% CI: 1.132-24.176, p=0.034), and presence of esophageal varicose veins. CONCLUSION: Although thrombocytopenia and splenomegaly may predict the presence of large esophageal varices, cirrhosis histopathology is the main factor in the presence of varices.

Turkish doctors' cohort: healthy despite low screening.

OBJECTIVES: We aimed to determine the prevalence of chronic diseases and unhealthy lifestyle behaviors of Turkish doctors as compared with the general population and the frequency of compliance with preventive clinical practices among doctors. METHODS: This was an observational, prospective cohort study that enrolled graduates between 1975 and 2004 from six medical schools in Turkey. Data on demographics, disease conditions, and unhealthy lifestyle behaviors were gathered. Preventive care practices were analyzed with regards to age and gender. RESULTS: A total of 7228 doctors participated in the study. Comparison with the national data revealed higher hyperlipidemia and coronary artery disease rates. While 54.5% of the doctors had a doctor visit in the last 12 months, only 31.5% of those over 40 years of age reported a recent blood pressure measurement. Colon cancer screening rate over 50 years of age with any of the acceptable methods was only 3%. One-fourth of the female doctors over 40 years of age underwent mammography within the last two years. Only 7.1% of the doctors over 65 years of age and 10% of the doctors having an indication for a chronic disease had a pneumococcal vaccine, while nearly one-fifth had no hepatitis B vaccine. CONCLUSION: In this cohort of mainly middle-aged Turkish doctors, the age-standardized rates of chronic diseases were lower than the rates in the general population except for the rates of hyperlipidemia and coronary artery disease. However, doctors did show quite low rates of receipt of screening practices. These results might provoke questions about how to use Turkish doctors' health behaviors to further improve doctors' and, relatedly, patients' health.

High Dose Oral Furosemide with Salt Ingestion in the Treatment of Refractory Ascites of Liver Cirrhosis.

PURPOSE: We aimed to evaluate and compare the efficacy and safety of high-dose furosemide+salt orally by comparing HSS+ furosemide (i.v.) and repeated paracentesis in patients with RA. METHODS: This was a prospective study of 78 cirrhotic patients with RA, randomized into three groups: Group A (n= 25) i.v. furosemide (200-300 mg bid) and 3% hypotonic saline solution (HSS) (once or twice a day); Group B (n= 26) oral furosemide tablets (360-520 mg bid) and salt (2.5 g bid); and, Group C (n= 27) repeated large-volume-paracentesis (RLVP) with albumin infusion. Patients without hyperkalemia were administrated 100 mg of spironolactone/day. During the follow-up; INR, creatinine, and total bilirubin levels were measured to determine the change in MELD (model of end stage liver disease) score. RESULTS: Hepatic encephalopathy (HE), severe episodes of spontaneous bacterial peritonitis (SBP) and pleural effusions (PE) occurred more frequently in Group C. Improvement in Child-Pugh and MELD score was better in Group A and B than Group C. In Group B, improvements were seen in the Child-Pugh and MELD score, reduction in body weight, duration and number of hospitalization. In Groups A and B, remarkable increases in diuresis were observed (706±116 to 2425±633 mL and 691±111 to 2405±772 mL) and serum sodium levels also improved. HE and SBP were occurred more often in group C (p<0.002). Hospitalization decreased significantly in Group B (p<0.001). There was no significant difference in survival among groups. CONCLUSION: High dose oral furosemide with salt ingestion may be an alternative, effective, safe and well-tolerated method of therapy for RA.

Nasobiliary Drainage for Benign Recurrent Intrahepatic Cholestasis in Patients Refractory to Standard Therapy.

PURPOSE: Benign recurrent intrahepatic cholestasis (BRIC) is characterized by episodic cholestasis and pruritus without anatomical obstruction. The aim of this study was to evaluate the safety and efficacy of nasobiliary drainage (NBD) in patients with BRIC refractory to medical therapy and to determine whether the use of NBD prolongs the episode duration. METHODS: This was a multicenter retrospective study consisting of 33 patients suffering from BRIC. All patients were administrated medical treatment and 16 patients who were refractory to standard medical therapies improved on treatment with temporary endoscopic NBD. Duration of treatment response and associated complications were analyzed. RESULTS: Sixteen patients (43% females) underwent 25 NBD procedures. The median duration of NBD was 17 days. There were significant improvements in total and direct bilirubin and alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and gamma-glutamyl transpeptidase on the 3rd day of NBD. Longer clinical remission was monitored in the NBD group. Post-endoscopic retrograde cholangiopancreatography pancreatitis was observed in one of 16 cases. CONCLUSION: NBD effectively eliminates BRIC in all patients and improves biomarkers of cholestasis. It can be suggested that patients with attacks of BRIC can be treated with temporary endoscopic NBD; however, the results of this study should be confirmed by prospective studies in the future.

Viral hepatitis screening guideline before biological drug use in rheumatic patients.

Biological drugs (tumor necrosis factor inhibitors, rituximab, tocilizumab, abatacept, and tofacitinib) are important treatment alternatives in rheumatology, particularly for resistant patients. However, they may cause hepatitis B virus (HBV) and hepatitis C virus (HCV) reactivation; for instance, HBV reactivation may occur in a patient who is an inactive hepatitis B surface antigen (HBsAg) carrier or who has resolved HBV infection. Therefore, the screening of patients before biological treatment and the application of a prophylactic treatment, particularly with respect to latent HBV infections, are recommended when necessary. This guideline covers pre-treatment screening and follow-up recommendations, if required, with respect to viral hepatitides in rheumatology patients who are planned to be given biological drugs. Although this guideline is prepared for biological disease-modifying antirheumatic drugs (DMARDs), it is recommended to be used also for target-oriented DMARDS and medium-high dose corticosteroids (>7.5 mg prednisolone/day equivalent). It should be considered that the reactivation risk is higher when more than one immunosuppressive drug is used.

The importance of salivary cortisol in the diagnosis of adrenal insufficiency in cirrhosis.

BACKGROUND/AIMS: Reports on adrenal insufficiency (AI) are unexpectedly high in cirrhosis, and the diagnosis of this condition remains a challenge. We aimed to define the prevalence rate of AI in stable cirrhotic patients and determine the correlations of free cortisol and salivary cortisol with total cortisol. MATERIALS AND METHODS: Between January 2011 and September 2011, 110 consecutive cirrhotic patients without any infection or hemodynamic instability were enrolled. Baseline total and salivary cortisol levels were measured. The free cortisol level was calculated according to the Coolens' formula. Post-stimulation total and salivary cortisol levels were measured, and the free cortisol level was recalculated. RESULTS: The mean age of the patients was 62.1±11.4 years. There were 54 males (49.1%). The mean Child-Turcotte-Pugh (CTP) score was 7.2±2.3. Twenty-two (20%) patients were at the CTP-C level. AI was present in 23 (20.9%) and 17 (15.5%) of all patients according to the total and free cortisol criteria, respectively. For basal and stimulated levels, salivary cortisol rather than total cortisol correlates well with free cortisol. CONCLUSION: The diagnosis of AI on the basis of total cortisol measurement overestimates the prevalence of AI in cirrhosis. Salivary cortisol, which correlates well with free cortisol, is a promising alternative for the diagnosis of AI in cirrhotic patients.

Autonomic neuropathy and gallbladder motility in patients with liver cirrhosis.

BACKGROUND/AIMS: Impaired gallbladder motility has been suggested as a contributor to increased incidence of gallstones in patients with liver cirrhosis. The purpose of this study was to determine gallbladder function and its relation with autonomic neuropathy in liver cirrhosis. MATERIALS AND METHODS: Gallbladder function was measured using ultrasonography in 48 patients with liver cirrhosis and in 31 controls. Autonomic neuropathy tests were applied in patients with liver cirrhosis. Patients with liver cirrhosis were analyzed in subgroups according to the severity of disease using the Child-Pugh classification. RESULTS: Fasting gallbladder volume was 16.2 mL (range: 2.1 mL-71.9 mL) in patients and 17.6 mL (range: 4.9 mL-76.6 mL) in controls. There were no differences in fasting gallbladder volume among the study groups (p>0.05). Gallbladder ejection fraction was significantly higher in patients compared with controls (84% vs. 65%) (p<0.001). No correlation was found between gallbladder ejection fraction and autonomic neuropathy (p>0.05). CONCLUSION: Our results indicate that liver cirrhosis does not impair gallbladder emptying, and that there is no association between gallbladder motility and autonomic neuropathy. Further investigations are required to explain increased gallbladder motility in liver cirrhosis.

Trends in colorectal cancer by subsite, age, and gender over a 15-year period in Adana, Turkey: 1993-2008.

BACKGROUND/AIMS: Analyzing temporal trends in cancer incidence rates can generate new insights for the significance of geographical and epidemiological variations of the disease. This study evaluated the time trends over a 15-year period in the frequencies of colon and rectum cancers at various subsites by gender and age. MATERIALS AND METHODS: Data were obtained from a populationbased cancer registry in Adana (a Mediterranean city of Turkey). Among the 47.783 microscopically-confirmed cancer cases during the 15-year period (1993 to 2008), 2.749 (5.8%) colorectal cancer cases were analyzed in three separate 5-year time periods. RESULTS: The incidence of right-sided colon cancer was found to be increasing compared to the left-sided colon cancer (p=0.048) over time in total (19.8% in 1993-1997, 24.4% in 1999-2003, and 25.6% in 2004-2008). This proximal shift of cancers demonstrated a significant increase for females (p=0.041), but not for males. The incidence of right-sided colon cancer was found to increase in advanced age groups (over 70) of males and increase in younger age groups (over 50) of females. There was a corresponding continuous decline in the percentage of rectal cancer (not in distal cancers) in both genders. CONCLUSIONS: Although the frequency of colorectal cancer cases was found to be lower in our country when compared to Western countries, a similar right-sided colon cancer shift was observed. The apparent shift of colorectal cancer in young female patients may be related to the advances in diagnostic techniques and may indicate possible diagnostic bias for the female gender. These results also emphasize the importance of collecting regular cancer statistics and of closer follow-up to generate basic epidemiological data and to draw attention to this issue in further detailed analytical research studies.

Risk factors for higher anti-HCV positivity in a border city in southern Turkey with unique population characteristics.

BACKGROUND/AIMS: This study was conducted as a seroprevalence study on hepatitis C virus infection in a small city located in southern Anatolia, to estimate the prevalence of hepatitis C virus and to explore the potential risk factors for hepatitis C virus infection at this population level. MATERIAL AND METHODS: A total of 1427 (685 male (48%), 742 female) subjects agreed to participate in the study. Risk factors were examined using a questionnaire. All blood samples were tested using third-generation anti-hepatitis C virus enzyme-linked immunosorbent assays. RESULTS: The overall anti-hepatitis C virus prevalence was 3.1% (44/1427). There was a steady rise in the prevalence of anti-hepatitis C virus positivity with age; the anti-hepatitis C virus prevalence was slightly higher in men (3.6%) than women (2.6%). The prevalence of anti-hepatitis C virus positivity was significantly higher in primary school graduates (3.4%) (odds ratio [OR]: 4.1, 95% confidence interval [CI]: 1.5-11.6, p=0.0001) and in illiterate subjects (5.0%) (OR: 2.7, 95% CI: 1.1-7.4, p=0.021) compared to secondary-plus graduates. Anti-hepatitis C virus positivity was higher (3.7%) in married subjects (OR: 8.7, 95% CI: 1.2-63.7, p=0.003) compared to single subjects (0.0%). Having dental procedure, delivery at home, provocative abortion, working abroad, hypertension, and diabetes mellitus were factors found to increase the anti-hepatitis C virus positivity significantly. CONCLUSIONS: In the region of the current study, the anti-hepatitis C virus seroprevalence was higher compared to the whole country. Illiteracy, previous dental procedures, and working abroad in neighboring countries seem to be factors that relate to this high ratio.

Early effect of peginterferon alpha-2b plus ribavirin treatment on blood pressure and insulin resistance in patients with chronic hepatitis C.

BACKGROUND/AIM: To investigate the early effects of peginterferon alpha-2b plus ribavirin therapy on blood pressure and related cardiovascular risk parameters, and also insulin resistance in patients with chronic hepatitis C virus (HCV) infection. METHODOLOGY: Twenty-nine patients with chronic hepatitis C (CHC) were enrolled in the study. Twenty-four hour ambulatory blood pressure monitoring (ABPM) of all patients was recorded in the pre-treatment period, and after the 1st and 8th weeks of treatment. Lipid profile, insulin resistance (IR), body mass index (BMI), complete blood counts and transaminase levels were also recorded at the same time periods. RESULTS: Fifteen of the 29 patients studied were hypertensive before treatment. The baseline, 1st week and 8th week recordings of ABPM (daytime, nighttime, mean systolic and diastolic measurements) did not show any significant change. Among hypertensive patients, differences in pretreatment, 1st and 8th week of treatment values of median systolic and diastolic blood pressures were not statistically significant. After the 8th week, total cholesterol, LDL, HDL, hemoglobin, white blood cell, platelet and AST/ALT were significantly decreased (p<0.05). Serum triglyceride levels increased significantly (p<0.0001) and HOMA-IR decreased (p=0.07). CONCLUSION: Peginterferon alpha-2b plus ribavirin therapy did not cause any increase in blood pressure in hypertensive and normotensive CHC patients in the early period of treatment. This treatment resulted in early but not significant changes in the IR status of CHC patients.

The effect of decrease in serum nitric oxide concentration on portal hemodynamics after Helicobacter pylori treatment: an open-label pilot study.

BACKGROUND/AIMS: Helicobacter pylori-induced gastritis increases serum nitrate and nitrite concentrations. The relationship between splanchnic hemodynamics and nitrate and nitrite levels has been demonstrated. We aimed to determine the effect of Helicobacter pylori eradication treatment on portal hemodynamics. METHODS: Nineteen patients with liver cirrhosis and Helicobacter pylori gastritis were included. Nine patients had esophageal varices indicating over portal hypertension. After histopathologic examination of gastric mucosa, Doppler ultrasonographic measurement of the portal veins and serum sampling to determine nitrate and nitrite concentration, treatment for Helicobacter pylori eradication was initiated for each patient. Evaluation of histopathology, Doppler measurements and sampling for serum nitrate and nitrite levels were repeated six weeks after the end of therapy. RESULTS: The rate of eradication of Helicobacter pylori was 73.7%. The median inflammation score, Helicobacter pylori density, and the median serum concentration of nitrate and nitrite decreased significantly after therapy (p values were 0.021, 0.001, and 0.018, respectively). After treatment, the patients with varices showed significant decreases in serum nitrate and nitrite levels whereas those without varices did not. Considering portal measurements, alteration in the congestion index approached statistical significance (0.15 versus 0.1; p=0 .066) in the patient group with varices. CONCLUSIONS: Reducing effect of Helicobacter pylori eradication treatment on serum nitrate and nitrite concentration seems to have some beneficial influence on portal hemodynamics.

Thrombopoietin or interleukin-6 has no effect on thrombocytopenia of cirrhosis.

BACKGROUND/AIMS: We aimed to compare the level of thrombocytopenia in cirrhotic patients with HBV and those with HCV, and to investigate whether the reduced serum level of IL-6 in patients with HCV is responsible for the lower platelet count compared to those with HBV through the effect on serum thrombopoietin level. METHODOLOGY: Fifty-three patients with liver cirrhosis, 28 of who were HBV- seropositive (Group A), 25 of who were HCV- seropositive (Group B) and 15 healthy controls were enrolled in this study. RESULTS: Platelet count in group B [75 (1.5-99) K/microL] were lower than those of group A [140 (62-374) K/microL] (p < 0.001). The median levels of serum thrombopoietin in patients [group A: 31.9 (31-113) pg/mL and group B: 38.0 (31.2-102) pg/mL] and controls [31.3 (31-153) pg/mL] did not show statistically significant difference. The patients compared to controls, had higher serum IL-6 levels [3.6 (2-1150) vs. 2.0 (2-9.9) pg/mL], (p < 0.01), which showed similarity in group A and B patients [3.65 (2-1150) vs. 3.3 (2-45) pg/mL], (p=NS). Serum thrombopoietin level was not correlated with serum IL-6 levels in any group. Serum thrombopoietin and IL-6 levels had no relationship with platelet count and with Child-Pugh score. CONCLUSIONS: Our study showed that cirrhotic patients with HCV had lower platelet count than those with HBV and controls, and this difference does not appear to be related with either serum thrombopoietin or IL-6 level.

Methylenetetrahydrofolate reductase C677T mutation and nonalcoholic fatty liver disease.

A mutation in the methylenetetrahydrofolate reductase (MTHFR) gene is known as one of the causes of hyperhomocyteinemia. The oxidation products of homocysteine can initiate lipid peroxidation, which has a central role in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). We aimed to assess the possible role of the MTHFR C677T mutation in the progression of simple steatosis to an advanced form of NAFLD. Thirty-four patients with NAFLD diagnosed by histologic analysis and 282 healthy controls were included in the study. The discrimination of nonalcoholic steatohepatitis (NASH) from another NAFLD was made by NAFLD activity score (NAS), and a NAS>or=5 was considered NASH. Patients with either NASH or nonalcoholic fatty liver (NAFL) and controls were evaluated for frequency of the MTHFR C677T mutation. The frequency of the MTHFR C677T mutation was 53.5% (CT, 44.7%; TT, 8.9%) in controls and 41.5% (CT, 37.7%; TT, 3.8%) in patients (odds ratio [OR], 0.62; 95% confidence interval [CI], 0.34-1.12). There was no statistical difference in the frequency of this genotype between patients with NAFL and those with NASH (36% [CT, 28%; TT, 8%] vs 46.4% [CT, 46.4; TT, 0%]; OR, 0.65; 95% CI, 0.22-1.96). According to this study, the MTHFR C677T mutation does not seem to be a risk factor for the progression of NAFL to NASH.

Effect of anti-HCV positivity on markers of malnutrition and inflammation in hemodialysis patients.

AIM: To investigate the influence of anti-HCV positivity on markers of malnutrition and inflammation in hemodialysis (HD) patients. METHODS: Stable HD patients who had persistently negative or positive HCV antibodies (at least three) and without elevated aminotransferase levels in routine periodical tests with a duration of more than 12 months were included. Patients with conditions known to be associated with acute-phase responses or clinically active (HCV RNA positive) or advanced liver failure were excluded. Thirty-six anti-HCV-positive patients (22 male, 14 female, mean age 47.3 +/- 14.5 years, mean time on HD 72.0 +/- 39.0 months), were compared with 36 anti-HCV negative patients with similar age and HD duration (25 male, 11 female, mean age 49.2 +/- 13.8 years, mean time on HD 59.7 +/- 27.1 months). Malnutrition-Inflammation Score (MIS), a fully quantitative score adopted from subjective global assessment, was recorded for each patient (ranges from 0 to 30). High sensitivity serum C-reactive protein (hs-CRP), interleukin-6 (IL-6), erythrocyte sedimentation rate (ESR), and hematocrit-corrected ESR were compared as indices of the degree of inflammation beyond anthropometric evaluation and routine laboratory tests. RESULTS: There was no significant difference in MIS of two groups (6.1 +/- 3.2 vs. 5.6 +/- 3.2, p > 0.05). In the comparison of components of MIS, co-morbidity including number of years on dialysis was higher in anti-HCV-positive patients (p = 0.04). Anthropometric values and serum levels of hs-CRP, IL-6, ESR, and hematocrit-corrected ESR of two groups were not statistically different from each other (p > 0.05 for all). ALT (p = 0.0001) and AST (p = 0.001) levels were higher in anti-HCV-positive patients. CONCLUSION: Anti-HCV positivity without active infection seems to have no additional negative effect on malnutrition and inflammation in maintenance HD patients.

Ultrasonographic evaluation of gallbladder functions in patients with irritable bowel syndrome.

BACKGROUND: The aim of the present study was to evaluate gallbladder function in irritable bowel syndrome (IBS) patients. METHODS: The functions of gallbladder were investigated every 30 min for 4 h. In addition, ejection fraction of the gallbladder was calculated from the fasting and post-prandial volumes. RESULTS: In IBS patients and healthy controls, fasting gallbladder volumes were 19.64 +/- 3.09 mL and 20.04 +/- 1.82 mL, and residual volumes after 3 h were 3.36 +/- 6.82 mL and 9.74 +/- 1.50 mL. Except for the residual volume after 3 h, all these results were not statistically significant. Residual volume after 3 h was statistically significantly lower in the IBS patients than in the controls (P < 0.001). Ejection fraction of the gallbladder was significantly higher in the IBS patients than in the controls (84% vs 55%, P < 0.001). CONCLUSIONS: Gallbladder contraction in patients with IBS was not different from that of a control group at post-prandial second hour but was signigicantly more pronounced at the end of 3 h when compared with controls. Ejection fraction of the gallbladder was higher in IBS patients when compared with controls.

Helicobacter pylori eradication lowers serum homocysteine level in patients without gastric atrophy.

AIM: To determine whether Helicobacter pylori (H pylori)infection caused hyperhomocysteinemia by altering serum vitamin B(12), serum folate and erythrocyte folate levels and whether eradication of this organism decreased serum homocysteine level. METHODS: The study involved 73 dyspeptic H pylori-positive patients, none of them had gastric mucosal atrophy based on rapid urease test and histology. Out of 73 patients, 41 (56.2%) showed a successful eradication of H pylori 4 wk after the end of treatment. In these 41 patients, fasting serum vitamin B(12), folate and homocysteine levels, and erythrocyte folate levels before and 4 wk after H pylori eradication therapy were compared. RESULTS: The group with a successful eradication of H pylori had significantly higher serum vitamin B(12) and erythrocyte folate levels in the post-treatment period compared to those in pre-treatment period (210+/-97 pg/mL vs 237+/-94 pg/mL, P<0.001 and 442+/-212 ng/mL vs 539+/-304 ng/mL, P = 0.024, respectively), but showed no significant change in serum folate levels (5.6+/-2.6 ng/mL vs 6.0+/-2.4 ng/mL, P = 0.341). Also, the serum homocysteine levels in this group were significantly lower after therapy (13.1+/-5.2 micromol/L vs 11.9+/-6.2 micromol /L, P = 0.002). Regression analysis showed that serum homocysteine level was positively correlated with age (P = 0.01) and negatively with serum folate level before therapy (P = 0.003). CONCLUSION: Eradication of H pylori decreases serum homocysteine even in patients who do not exhibit gastric mucosal atrophy. It appears that the level of homocysteine in serum is related to a complex interaction among serum vitamin B(12), serum folate and erythrocyte folate levels.
