Role of hepatosteatosis in HBsAg seroconversion in HBeAg-negative chronic hepatitis B patients.

BACKGROUND: In chronic Hepatitis B virus (HBV) infection, certain individual and viral characteristics such as advanced age, presence of hepatic steatosis (HS), normal ALT levels, initially negative HBeAg and HBV DNA, and genotype of the virus are associated with HBsAg seroclearance and seroconversion. Herein, we report the results of our study evaluating the association between hepatosteatosis and HbsAg seroconversion. METHODS: The clinical and biochemical data of patients with CHB and hepatosteatosis (HS) (HBsAg seroconversion, n:52, and non-HbsAg seroconversion, n:352), and the rate of development of HBsAg seroconversion were evaluated. RESULTS: We collected data from 404 patients with HBeAg negative CBH (mean age ± SD: 36.2 ± 11 years; 223 [55.2%] men, 181 [44.8%] women). The mean age at diagnosis of disease was 36.2 ± 11 years. The mean duration of the disease was 10.6 ± 7 years. Seroconversion developed in 52 patients (12.8%) with serum HBsAg positive (mean ± SD: 12.7 ± 5.8). Elderly age and the duration of disease time were significantly associated with seroconversion (P < .001). The presence of serum HBsAg seroconversion was significantly associated with hepatosteatosis (OR: 3.06, 95% CI 1.64-5.71, P < .01). Serum HBsAg seroconversion was more frequent in patients with mild HS than patients with moderate-severe HS (P = .04). In multivariate regression analysis, the presence of HS was found to be an independent factor predicting the development of HBsAg seroconversion (OR: 2.07 95% GA:1.07-4.0 P = .03). CONCLUSION: The presence of mild HS in HBeAg negative chronic hepatitis B patients contributes to HBsAg seroconversion. Further studies are required to better understand the relationship between steatosis and HBsAg seroconversion.

Predictive value of C-reactive protein/albumin ratio in acute pancreatitis.

BACKGROUND: Serum C-reactive protein (CRP) increases and albumin decreases in patients with inflammation and infection. However, their role in patients with acute pancreatitis is not clear. The present study was to investigate the predictive significance of the CRP/albumin ratio for the prognosis and mortality in acute pancreatitis patients. METHODS: This study was performed retrospectively with 192 acute pancreatitis patients between January 2002 and June 2015. Ranson scores, Atlanta classification and CRP/albumin ratios of the patients were calculated. RESULTS: The CRP/albumin ratio was higher in deceased patients compared to survivors. The CRP/albumin ratio was positively correlated with Ranson score and Atlanta classification in particular and with important prognostic markers such as hospitalization time, CRP and erythrocyte sedimentation rate. In addition to the CRP/albumin ratio, necrotizing pancreatitis type, moderately severe and severe Atlanta classification, and total Ranson score were independent risk factors of mortality. It was found that an increase of 1 unit in the CRP/albumin ratio resulted in an increase of 1.52 times in mortality risk. A prediction value about CRP/albumin ratio >16.28 was found to be a significant marker in predicting mortality with 92.1% sensitivity and 58.0% specificity. It was seen that Ranson and Atlanta classification were higher in patients with CRP/albumin ratio >16.28 compared with those with CRP/albumin ratio ≤16.28. Patients with CRP/albumin ratio >16.28 had a 19.3 times higher chance of death. CONCLUSION: The CRP/albumin ratio is a novel but promising, easy-to-measure, repeatable, non-invasive inflammation-based prognostic score in acute pancreatitis.

Clinical and histological features of idiosyncratic liver injury: Dilemma in diagnosis of autoimmune hepatitis.

AIM: Drug-induced liver injury (DILI) is becoming a worldwide problem with its still unexplained properties. METHODS: The data of patients who were diagnosed with DILI between January 2008 and December 2013 were assessed. RESULTS: Five patients had been diagnosed with intrinsic and 82 patients with idiosyncratic DILI. The most common causative agents were antimicrobial drugs. The most common injury pattern was hepatocellular. When patients with bilirubin levels of more than 5 mg/dL were divided into two groups according to receiving steroid therapy (n = 11) or not (n = 40), there was not any significant difference according to their clinical results (P > 0.05). Five of the idiosyncratic DILI patients were diagnosed with drug-induced autoimmune hepatitis (DI-AIH). In histopathological examination, hepatic rosette formation and emperipolesis were observed to be more common among patients with DI-AIH when compared with ones without (P < 0.05). Interestingly, in the remaining patients with DILI (n = 77), three of them were diagnosed with classic autoimmune hepatitis during long-term follow up (range, 11-51 months). CONCLUSION: The most common causes were antimicrobials, but any agents that have not been defined to cause DILI can induce DILI. The efficacy of steroids in DILI has not been observed but all deaths were observed in the steroid-free group. The association of DILI and AIH was observed in two different types in terms of diagnosis in our study. The first association was DI-AIH. The second one is the classical AIH which developed in three patients after a few months following spontaneous recovery of DILI.

Pregabalin: A New Adjunct in Calcineurin Inhibitor Pain Syndrome Treatment.

Tacrolimus and cyclosporin are calcineurin inhibitors (CIs) commonly used in organ transplants. These agents rarely cause a severe, debilitating pain syndrome of especially lower extremities, known as CI pain syndrome (CIPS). Although the pathogenesis is not well understood, neuropathic pain mechanisms have started to be discussed in the recent literature. Here, presenting a 48-year-old male with CIPS who recovered after pregabalin 150 mg twice daily, we aimed to emphasize the importance of this syndrome and offer a new approach for the treatment. This is the first report in the literature where pregabalin is demonstrated to be effective in CIPS.

Prevalence of Pancreatic Steatosis and Its Associated Factors in Turkey: A Nation-Wide Multicenter Study.

BACKGROUND/AIMS:  Pancreatic steatosis (PS) is a pathology associated with metabolic syndrome (MS), endocrin and exocrine disfunctions of the pancreas, and fatty liver. The data on the frequency of PS are very limited. We aimed to evaluate the frequency of PS detected by transabdominal ultrasonography (TAU) in gastroenterology clinics located in different geographical regions of Turkey and the factors associated with it. MATERIALS AND METHODS:  Volunteers were evaluated by TAU for PS and hepatosteatosis (HS), and its degree. Pancreatic stiffness was evaluated by ultrasonographic shear wave elastography (SWE). All demographic, physical, and biochemical parametres were measured. RESULTS:  A total of 1700 volunteers from 14 centers throughout Turkey were included in the study. Mean age was 48.03 ± 20.86 years (56.9% female). Prevalance of PS was detected in 68.9%. In the PS group, age, body mass index (BMI), waist circumference, systolic blood pressure, fasting blood glucose (FBG), lipid levels, insulin resistance, diabetes mellitus, hypertension, MS frequency, and pancreatic SWE score were increasing, and fecal elastase level was decreasing in correlation with the degree of PS. The frequency of HS was 55.5%. Hepatosteatosis [odds ratio (OR): 9.472], increased age (OR: 1.02), and BMI (OR: 1.089) were independent risk factors for the occurrence of PS. Lean-PS rate was 11.8%. The lean-PS group was predominantly female and younger than non-lean PS. Also it has lower blood pressure, FBG, liver enzymes, lipid levels, and HS rates. CONCLUSION:  The frequency of PS was found 68.9% in Turkey. Its relationship was determined with age, BMI, HS, MS (and its components), pancreatic stiffness, and fecal elastase level.

Effect of Pretransplant Sarcopenia on Mortality in Liver Transplant Recipients.

OBJECTIVES: Sarcopenia is an important metabolic disorder associated with end-stage liver disease and is an independent predictor of mortality in liver transplant candidates. We evaluated effects of pretransplant muscle mass, muscle quality, and visceral adipose tissue on mortality after liver transplant. MATERIALS AND METHODS: For 2015-2020, we included 65 liver transplant recipients whose records contained pretransplant liver computed tomography images. We calculated skeletal muscle mass index (muscle tissue area in centimeters squared divided by height in meters squared), visceral-to-subcutaneous fat ratio (visceral adiposity indicator), and intramuscular adipose tissue content ratio (muscle quality indicator). RESULTS: Median age was 55 years (IQR, 45-63 years), and 48 (73.8%) patients were men. During follow-up, 53 (81.5%) study group patients survived; mean survival time was 71.73 ± 3.81 months. The deceased patient group had a statistically higher pretransplant visceral-to-subcutaneous fat ratio than the survival group (P = .046). Survival was 100% for 1 positive indicator, 86.2% for 2 positive indicators, and 70.4% for 3 positive indicators (P = .096). Positive correlation was confirmed between pretransplant skeletal muscle mass index and age (P = .043) and pretransplant body mass index (weight in kilograms divided by height in meters squared) (P < .001). There was a moderate positive correlation between pretransplant intramuscular adipose tissue content ratio and age (R = 0.529, P ≤ .001) and a weak positive correlation with pretransplant body mass index (R = 0.361, P = .003). Furthermore, pretransplant visceral- tosubcutaneous fat ratio showed a weak positive correlation with age (R = 0.306, P = .013) and a weak negative correlation with the Model for End-Stage Liver Disease score (R = -0.301, P = .016). CONCLUSIONS: Pretransplant sarcopenia is an important indicator to predict mortality and morbidity in posttransplant follow-up. Visceral-to-subcutaneous fat ratio is an important parameter to evaluate sarcopenia in liver transplant patients.

Investigating Whether the Severity of SARS-CoV-2 Infection Is Higher in Liver Transplant Recipients: A Single-Center Experience.

OBJECTIVES: Liver transplant recipients have been reported to be a high-risk population for severe disease from COVID-19 infection. In this crosssectional, single-center study, we investigated whether liver transplant increased the risk of death and severe disease in patients with SARS-CoV-2 infection. MATERIALS AND METHODS: We collected data and serum anti-SARS-CoV-2 immunoglobulin M and immunoglobulin G results of 91 liver transplant recipients seen from September 2020 to March 2021. Liver transplant recipients were enrolled during presentation for scheduled routine follow-up visits. All patients who required serum anti-SARS-CoV-2 immunoglobulin M and immunoglobulin G tests completed a ques-tionnaire on clinical symptoms during the previous 6 months. RESULTS: Among the 91 patients with SARS-CoV-2 immunoglobulin M and G results, 7 patients had a known history of symptomatic COVID-19 during the previous 6 months. Of the 84 participants who completed the questionnaire, 21 (25%) had positive anti-SARS-CoV-2 immunoglobulin M and G results. These 21 patients also received COVID-19 polymerase chain reaction tests, which were negative in all 21 patients. Overall, only 7 patients stated that they experienced flu-like upper respiratory tract infection symptoms or diarrhea. CONCLUSIONS: We documented past SARS-CoV-2 infection in only 25% of our outpatient liver transplant recipients, and most were asymptomatic. We found no significant relationship between symptoms and seropositivity for SARS-CoV-2.

Gastric subepithelial masses: evaluation of multidetector CT (multiplanar reconstruction and virtual gastroscopy) versus endoscopic ultrasonography.

OBJECTIVES: To assess the role of multidetector computed tomography (MDCT) with multiplanar reconstruction (MPR) and virtual gastroscopy (VG) for detection and differentiation of gastric subepithelial masses (SEMs) by comparison with endoscopic ultrasonography (EUS). METHODS: Forty-one patients with a suspected SEM were evaluated using EUS and MDCT. MDCT findings were analyzed based on the consensus of two radiologists who were blinded to the EUS findings. The analysis of the CT features included the location, size, and contours of the tumor, the presence of central dimpling, as well as the growth pattern, enhancement pattern, and enhancement degree. The long diameter (LD) and the short diameter (SD) of each lesion were measured and the LD/SD ratios were calculated. EUS and MDCT results were compared with histopathology for the pathologically proven lesions. For the non-pathologically proven lesions, MDCT results were compared with EUS. RESULTS: Among the 41 patients, 34 SEMs were detected using EUS. For the detection of SEMs with MDCT, a sensitivity of 85.3%, a specificity of 85.7%, a positive predictive value of 96.7%, and a negative predictive value of 54.5% were calculated. The overall accuracy of MDCT for detecting and classifying the SEMs was 85.3 and 78.8%, respectively. CONCLUSIONS: MDCT with MPR and VG is a valuable method for the evaluation of SEMs. Specific MDCT criteria for various SEMs may be helpful in making an accurate diagnosis.

Double balloon enteroscopy: a 3-year experience at a tertiary care center.

BACKGROUND/AIMS: To evaluate the indications, diagnostic yield, therapeutic interventions, complications and safety of double balloon enteroscopy (DBE) in clinical practice. METHODOLOGY: The medical records of the patients who underwent DBE at the Turkiye Yuksek Ihtisas Hospital between October 2007 and January 2010 were examined to note the demographic data, indications for the examination, results of previous non-invasive small bowel imaging and endoscopic procedures and the results of DBE including findings, endoscopic interventions, complications and pathological reports. RESULTS: A total of 139 procedures were performed in 118 patients. DBE was performed 81 times through mouth and 26 times through anus and additionally both approaches were used 16 times in the same patients. Panenteroscopy was successfully performed in 13 of 16 patients (87.5%) in whom it was attempted. The most common indication was obscure gastrointestinal bleeding (28.8%). DBE had an overall diagnostic and/or therapeutic contribution in 63 (53.4%) patients. The main pathologies detected on DBE were polyps (12.7%), infammation (10.7%) and vascular lesions (3.4%). Complications were recognized in four cases (3.4%) but no major complication occured. CONCLUSIONS: Our retrospective analysis showed that DBE is a useful, safe and well-tolerated method with a diagnostic and therapeutic impact for the management of small bowel diseases.

Similarities and Differences Between Gerontal and Young Patients with Acute Pancreatitis: Evaluation of Clinical Characteristics and Outcomes.

BACKGROUND: Acute pancreatitis is an abrupt inflammatory disease of the exocrine pancreas and it can occur in different severities. It is becoming more common and more mortal in the gerontal population. The aim of our study was to explore the similarities and differences between young and gerontal patients with acute pancreatitis, with a special emphasis on patients over 80 years of age. METHODS: Medical records of patients (n = 1150) with acute pancreatitis were analyzed retrospectively. Several scoring systems including Bedside index for severity in acute pancreatitis, Ranson's score, Harmless acute pancreatitis score, Acute Physiology and Chronic Health Evaluation, Balthazar Grade, Glasgow score, and Japanese severity score were applied at admission. Patients were divided into 3 groups; group I, young group (n = 706), if they were aged <65 years; group II, older group (n = 338), if they were aged ≥65 years to <80 years; group III, octogenarian group (n = 106), if they were aged ≥ 0 years. RESULTS: In total, 1150 patients with acute pancreatitis were analyzed. Octogenarian group (n = 42, 39.6%) showed a more severe acute pancreatitis compared to patients in group I (n = 15, 2.1%) and II (n = 50, 14.8%, P < .001). Complications were more common in patients in group III (P < .001). Mortality rate was higher in patients in group III (n = 53, 50%) compared to group I (n = 8, 1.1%) and group II (n = 53, 15.7%) (P < .001). CONCLUSION: Gerontal patients with acute pancreatitis tend to have more severe disease and systemic and local complications. Mortality rates were higher in older patients compared to younger patients.

ERCP experience in patients with choledochoduodenostomy: diagnostic findings and therapeutic management.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP), besides reducing the need for surgery in a wide spectrum of biliary disease, is increasingly be used for the treatment of biliary complications of surgery. In this paper, we review our experience with postoperative ERCPs required after biliary surgery with a special focus on side-to-side choledochoduodenostomy (CD). METHODS: The records of 70 patients with a history of CD who underwent ERCP from May 2000 to February 2006 were analyzed. RESULTS: There were 70 patients, 32 (45.7%) women and 38 (35.6%) men, with a mean age of 56 (range, 21-80) years. Indications for ERCP were cholangitis in 46 (65.7%), abnormal liver function tests with abdominal pain and abnormal USG in 22 (31.4%), and abnormal liver function tests and abnormal USG in 2 (2.9%). Overall 133 ERCP were performed. Anastomotic stenosis was found in 14 (20%), benign biliary stricture above the anastomosis in 13 (18.6%), sump syndrome in 11 (15.7%), common bile duct stone in 8 (11.4%), malignancy in 4 (5.7%), hepatolithiasis in 1 (1.4%), and secondary sclerosing cholangitis in 1 (1.4%). ERCP was normal in 18 (25.8%). Patients were managed by stone extraction in 8 (11%), stent insertion in 22 (36%), balloon dilatation in 15 (21%), nasobiliary drainage in 11 (16%), and bougie dilatation in 2 (3%) patients. CONCLUSIONS: We have reported one of the largest groups of patients with CD in the literature and showed that ERCP is a very important diagnostic and therapeutic tool for the management of biliary problems after CD.

Does interleukin-18 play a role in the pathogenesis of hepatic encephalopathy?

BACKGROUND/AIMS: It has been suggested that the presence of inflammation may accentuate the neuropsychologic alterations in hepatic encephalopathy (HE). The aim of the study was to investigate any association between alterations in plasma levels of the pro-inflammatory cytokine IL-18 and HE. METHODOLOGY: The study population included 63 patients with cirrhosis and 20 healthy controls. Laboratory data included international normalized ratio, plasma albumin, bilirubin, urea, creatinine, hsCRP and IL-18 (pg/mL). HE was assessed using West Haven criteria and critical flicker frequency (CFF) measurement. RESULTS: Forty-two of the 63 cirrhotic patients had HE (4, 16, 21 and 1 patients in grade 0, 1, 2, 3, respectively). hsCRP and IL-18 were significantly increased in patients with HE compared with the control group (1.6 +/- 4.8 vs 0.5 +/- 0.8, p<0.001 and 121.4 (13.6-2043.6) vs 56.3 (13.0-174.0), p=0.006, respectively). The levels of hsCRP and IL-18 were significantly higher in the all cirrhotic patients than in the control subjects (p=0.002 and p=0.008 respectively). hsCRP was significantly higher in patients with HE (2.2 +/- 6) than in patients without HE (0.7 +/- 1.2) (p=0.013). The levels of IL-18 were found higher in patients with HE than in patients without HE [121.4 (13.6-2043.6) vs 103.8 (13.0-828.0)] but the difference was not significant (p=0.215). IL-18 was higher in patients with elevated hsCRP [124.6 (13.6-2043.6)] compared with those who had normal hsCRP [75.6 (13.0-753.2)] (p=0.029). CONCLUSION: There is an inflammatory response in the presence of cirrhosis and HE; and IL-18 may play a role in the perpetuation of chronic inflammation.

Ectopic opening of the common bile duct and duodenal stenosis: an overlooked association.

BACKGROUND: Ectopic opening of the common bile duct into the duodenal bulb (EO-CBD-DB) is a rare disease that may be complicated by duodenal ulcer, deformity, stenosis and biliary stones. The aim of this study is to report clinical presentations, endoscopic diagnosis and treatment of this entity as well as to investigate its association with duodenal stenosis. METHODS: Gastroduodenoscopic findings and radiological imaging were evaluated for ectopic papilla and duodenal stenosis. Diagnostic methods, endoscopic procedures and long-term outcomes of the endoscopic treatment were presented. RESULTS: EO-CBD-DB was found in 74 (77.1%) of the 96 patients with duodenal deformity/stenosis (79 male, 17 female, mean age: 58.5, range: 30-87 years). The papilla with normal appearance was retracted to the bulb in 11 while it was at its usual location in the remaining 11. The history of biliodigestive surgery was more common in patients with EO-CBD-DB who were frequently presented with the common bile duct stone-related symptoms than the other patients. Thirteen (17.6%) of the patients with EO-CBD-DB were referred to surgery. Endoscopic treatment was completed in 60 (81.1%) patients after an average of 1.7 (range: 1-6) procedures. These patients were on follow-up for 24.8 (range: 2-46) months. Endoscopic intervention was required in 12 (20%) of them because of recurrent biliary problems. Treatment of the patient who had stricture due to biliary injury during laparoscopic cholecystectomy is still continued. CONCLUSIONS: The presence of EO-CBD-DB should be considered particularly in middle-aged male patients who have duodenal deformity/stenosis. Endoscopic treatment is feasible in these patients. The long-term outcomes of endoscopic therapy need to be compared with surgical treatment.

Bezoar in upper gastrointestinal endoscopy: A single center experience.

BACKGROUND/AIMS: We aimed to investigate the association of bezoar with endoscopic findings, risk factors for bezoar occurrence, and the success of endoscopic treatment in a tertiary center. MATERIALS AND METHODS: This retrospective study was conducted between January 2012 and December 2015. Overall, 8200 endoscopy records were examined and 66 patients with bezoar were included in the study. RESULTS: We enrolled 29 (44%) female and 37 (56%) male patients in this study. The mean age of the patients was 63±9.4 years. The most frequent risk factors were history of gastrointestinal surgery (23%), diabetes mellitus (17%), trichophagia (9%), and anxiety disorder (6%). Gastric ulcer, duodenal ulcer, erosive gastritis, and reflux esophagitis were present in 27%, 11%, 20%, and 23% of the patients, respectively. While bezoars were most commonly observed in the stomach (70%), the majority of them were phytobezoars (91%). The mean number of interventions for each patient was 1.5 (range, 1-6). Endoscopy was successful in removing bezoars in 86.5% of the patients. Among those referred to surgery, seven patients underwent gastrostomy (10.5%); one (1.5%) patient underwent gastroenterostomy because of concomitant pyloric stenosis; and one (1.5%) patient underwent fistula repair surgery due to the development of duodenal fistula caused by bezoar. CONCLUSION: The findings of this study indicated that bezoars are more common among subjects with history of gastrointestinal surgery, diabetes mellitus, or psychiatric disorders; bezoars are closely related to peptic ulcer and reflux esophagitis; and they can be successfully treated with endoscopy.

Prevalence and characteristics of bone disease in cirrhotic patients.

Background and Aim: Chronic liver disease is a risk factor for osteoporosis, osteopenia and bone fractures. In this study, prevalence and risk factors of osteoporosis and vitamin D deficiency and also their effects on survival were investigated in 218 patients with chronic liver disease. Materials and Methods: Prevalence of osteoporosis and vitamin D levels was calculated. Risk factors for osteoporosis (gender, age, body mass index, etiology), serum bilirubin, albumin, 25-hydroxy (OH) vitamin D, parathyroid hormone levels, bone mineral density (BMD) with DEXA, bone formation (osteocalcin) and bone resorption (type 1 collagen) levels, Model for End-Stage Liver Disease (MELD) Na and Child-Pugh (CP) score were recorded. The effects of vitamin D levels and BMD on survival were evaluated. Results: One hundred forty-seven (67.4%) patients were female (mean age, 50.4±11.7). Patients were Child A by 40.8%, Child B by 47.1%, and Child C by 12.1%. Mean MELD Na score was 8.4±2.8. Data of the BMD were established in 218 patients and 25-OH D levels in 122 patients. Mean serum 25-OH D level was 14.26±9.44 ng/mL. Osteoporosis was identified in 42 (19.3%) and osteopenia in 115 (52.8%) patients, according to BMD. Osteocalcin levels and collagen type 1 levels were high in 25.6% and 12.5% of patients, respectively. No statistically difference was found, including gender (p=0.69), age (p=0.38), etiology (p=0.16), BMI (p=0.32), CP score (p=0.42), MELD (0.14), albumin (p=0.11), total bilirubin (p=0.99), Ca (0.67), PTH (0.88), osteocalcin (0.92), collagen type 1(p=0.25) between osteoporotic and non-osteoporotic patients. Patients were followed-up for a median of 30.07±11.83 months after BMD measurement. Fifty-four (24.8%) patients died during the follow-up period, none of them are related to bone fracture. There was no statistically difference on survival between osteoporosis group (32.2±2.3 months) and non-osteoporosis group (37.2±1.7 months; p=0.26) or when patients with 25-OH D3 ≤10 ng/mL were compared to patients with 25-OH D3 >20 ng/mL (34.4±2.0 months vs. 39.1±1.6 months, p=0.308). Conclusion: In conclusion, the prevalence of bone disease was found to be higher in cirrhotic patients. Although osteoporosis and vitamin D deficiency were found to decrease survival, this effect was not statistically significant. We suggest designing multi-institutional and/or multinational studies with larger and more heterogenous patient groups would enable better testing of this phenomenon.

Real-world efficacy and safety of Ledipasvir + Sofosbuvir and Ombitasvir/Paritaprevir/Ritonavir ± Dasabuvir combination therapies for chronic hepatitis C: A Turkish experience.

BACKGROUND/AIMS: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population. MATERIAL AND METHODS: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)±ribavirin (RBV) orombitasvir/paritaprevir/ritonavir±dasabuvir (PrOD)±RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed. RESULTS: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90±54.60 U/L to 17.00±14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51±4.54 to 7.32±3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0±16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%). CONCLUSION: LDV/SOF or PrOD±RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.

Bile reflux index after therapeutic biliary procedures.

BACKGROUND: Therapeutic biliary procedures disrupt the function of the sphincter of Oddi. Patients are potential "bile refluxers". The aim of this study was to assess how these procedures affect the histology-based bile reflux index (BRI), which can be used to reflect duodenogastric reflux (DGR). METHODS: Gastric antrum and corpus biopsies were collected from 131 subjects (56 men, 75 women; mean age, 55.9 +/- 15.6 years). Group 1 (Biliary group-BG; n = 66) had undergone endoscopic sphincterotomy, endoscopic stenting, or choledochoduodenostomy for benign pathology; Group 2 (n = 20) had undergone cholecystectomy alone; and Group 3 (n = 6) Billroth II gastroenterostomy. Group 4 (no cholecystectomy; n = 39) had upper endoscopy with normal findings and served as controls. BRI > 14 indicated DGR (BRI [+]). To eliminate confounding effects of Helicobacter pylori (Hp) infection, comparisons were made according to Hp colonization. RESULTS: Fifty-nine subjects (45%) were Hp (+). The frequencies of BRI (+) status in antrum and corpus specimens from Hp (-) BG patients were 74.3% and 71.4%, respectively (85.7% for both antrum and corpus for choledochoduodenostomy). Corresponding results were 60% and 60% for Group 2, 100% (only corpus) for Group 3, and 57.1% and 38.1% for controls (BG, Group 2, and Group 3 vs controls - p > 0.05 antrum, p < 0.05 corpus). Fifty-four BG patients had previously undergone cholecystectomy. Excluding those, the rates of BRI (+) in Hp (-) BG patients were 75% antrum and 62.5% corpus (p > 0.05 for both vs. Group 2). CONCLUSION: Patients who had undergone biliary procedures showed similar bile-related histological changes in both corpus and antrum biopsies, but the changes seen in controls were more prominent in the antrum than corpus. Therapeutic biliary procedures increase the rate of BRI (+) especially in the case of choledochoduodenostomy. Therapeutic biliary procedures without cholecystectomy also increase the rate of BRI (+) similar to that observed in patients with cholecystectomy.

P wave dispersion is prolonged in patients with Wilson's disease.

AIM: To investigate the P wave dispersion as a non-invasive marker of intra-atrial conduction disturbances in patients with Wilson's disease. METHODS: We compared Wilsonos disease patients (n = 18) with age matched healthy subjects (n = 15) as controls. The diagnosis was based on clinical symptoms, laboratory tests (ceruloplasmin, urinary and hepatic copper concentrations). P wave dispersion, a measurement of the heterogeneity of atrial depolarization, was measured as the difference between the duration of the longest and the shortest P-waves in 12 lead electrocardiography. RESULTS: All the patients were asymptomatic on cardiological examination and have sinusal rhythm in electrocardiography. Left ventricular and left atrial diameters, left ventricular ejection fraction and left ventricular mass index were similar in both groups. The Wilson's disease patients had a significantly higher P wave dispersion compared with the controls (44.7 +/- 5.8 vs 25.7 +/- 2.5, P < 0.01). CONCLUSION: There was an increase in P wave dispersion in cardiologically asymptomatic Wilson's disease patients which probably represents an early stage of cardiac involvement.

Rectal angiolipoma: a case report and review of literature.

Angiolipoma is a rare vascular variant of the benign lipomatous tumors and is generally seen in subcutaneous tissues. We report a 70-year-old female with abdominal distension not related to rectal small polypoid mass with peduncule described as angiolipoma by histologically, and review the literature.
