RESUMO
INTRODUCTION: For the treatment of spontaneous bacterial peritonitis (SBP), cefotaxime, ceftriaxone, and ciprofloxacin were used as first-line agents. However, considering the increasing rate of antibiotic resistance, it is unclear which of these drugs can be initially recommended. This study aimed to compare the current efficacy of the 3 antibiotics, namely cefotaxime, ceftriaxone, and ciprofloxacin, for the treatment of SBP in patients with cirrhosis with ascites, when guided by therapeutic responses. METHODS: This study was a multicenter, prospective, randomized controlled trial. The inclusion criteria were 16- to 75-year-old patients with liver cirrhosis with ascites, having polymorphonuclear cell count of >250/mm 3 . We performed a follow-up paracentesis at 48 hours to decide continuing or changing the assigned antibiotics and then assessed the resolution rates at 120 and 168 hours of treatment. RESULTS: A total of 261 patients with cirrhosis who developed SBP were enrolled. Most of the patients were diagnosed as those with SBP within 48 hours of admission. The resolution rates at 120 hours, which is the primary endpoint, were 67.8%, 77.0%, and 73.6% in the cefotaxime, ceftriaxone, and ciprofloxacin groups, respectively ( P = 0.388), by intension-to-treat analysis. The 1-month mortality was similar among the groups ( P = 0.770). The model for end-stage liver disease score and the SBP resolution were significant factors for survival. CONCLUSION: The efficacy of empirical antibiotics, such as cefotaxime, ceftriaxone, and ciprofloxacin, against SBP was not significantly different. In addition, these antibiotics administered based on response-guided therapy were still efficacious as initial treatment for SBP, especially in those with community-acquired infections.

BACKGROUND: An association between environmental pollutants and alcohol-related liver disease (ALD) has not been determined until now. The objectives of this study were to examine the association of the pollutants with ALD, and whether the pollutants together increased the risk of ALD. METHODS: Data were extracted from the Korea National Health and Nutrition Examination Survey (2010-2013 and 2016-2017; n = 11,993). Blood levels of lead, cadmium, and mercury were measured. ALD was defined by a combination of excessive alcohol consumption and ALD/non-alcoholic fatty liver disease index > 0. The aspartate aminotransferase-to-platelet ratio index and fibrosis (FIB)-4 score were used to evaluate ALD FIB. RESULTS: The odds ratios (ORs) of ALD for the highest versus the lowest quartiles of exposure were for lead, 7.39 (95% confidence interval [CI], 5.51-9.91); cadmium, 1.68 (95% CI, 1.32-2.14); and mercury, 5.03 (95% CI, 3.88-6.53). Adjusting for age, gender, smoking, occupation, education, and personal income attenuated the associations but indicated significant positive trends (all Ptrend < 0.001). A positive additive interaction between cadmium and lead was observed. The relative excess OR due to the interaction was 0.96 (95% CI, 0.41-1.51); synergy index = 2.92 (95% CI, 0.97-8.80). Among 951 subjects with ALD, advanced FIB was associated with lead and cadmium (OR, 3.46, 95% CI, 1.84-6.53; OR, 8.50, 95% CI, 2.54-28.42, respectively), but not with mercury. The effect estimates for lead and cadmium remained significant even after adjustment for daily alcohol intake. CONCLUSION: Blood levels of lead, cadmium, and mercury were significantly associated not only with the risk of ALD but also with ALD FIB. Cadmium and lead have synergistic effects that increase the risk of ALD.

BACKGROUND AND AIMS: The influence of direct-acting antivirals (DAAs) on chronic hepatitis C (CHC)-related hepatocellular carcinoma (HCC) remains controversial. We investigated the effect of eradicating CHC using DAAs on treatment outcomes in patients with CHC-related HCC treated with transarterial chemoembolization (TACE). METHODS: This nationwide, multi-center, retrospective study recruited patients with CHC-related HCC treated with TACE as the first-line anti-cancer treatment, and who achieved a sustained virological response (SVR) using DAAs (DAA group) between 2006 and 2017. Patients achieving an SVR following interferon-based treatment (IFN group) and those without treatment (control group) were also recruited for comparison. RESULTS: A total of 425 patients were eligible for the study. Of these, 356 (83.8%), 26 (6.1%), and 43 (10.1%) were allocated to the control, IFN, and DAA groups, respectively. A multivariate analysis showed that liver cirrhosis, segmental portal vein thrombosis, and larger maximal tumor size independently predicted an increased risk of progression (all p < 0.05), whereas, the DAA group (vs. IFN and control groups) independently predicted a reduced risk of progression (hazard ratio (HR) = 0.630, 95% confidence interval 0.411-0.966, p = 0.034). The cumulative incidence rate of HCC progression in the DAA group was significantly lower than that in the IFN and control groups (p = 0.033, log-rank test). In addition, the DAA group (vs. IFN and control groups) was independently associated with a reduced risk of mortality (p = 0.042). CONCLUSIONS: DAA treatment provided significantly prolonged progression-free survival in patients with CHC-related HCC treated with TACE compared to that in patients administered IFN or no treatment.

BACKGROUND: The advancement of treatment with direct-acting antiviral (DAA) agents has improved the cure rate of hepatitis C virus (HCV) infection close to 100%. The aim of our study was to assess the real-world effectiveness and safety of DAA regimens for the treatment of patients with chronic HCV genotype 2. METHODS: We retrospectively analyzed the clinical data of patients treated with sofosbuvir plus ribavirin (SOF + RBV) or glecaprevir/pibrentasvir (G/P) for chronic HCV genotype 2 infection at seven university hospitals in the Korean southeast region. RESULTS: SOF + RBV therapy produced an 89% and 98.3% sustained virologic response 12 week (SVR12) after treatment completion in the full analysis set and per-protocol set, respectively, and the corresponding values for G/P therapy were 89.5% and 99.2%, respectively. The difference between the treatments was probably because 6.2% (59/953) of patients in the SOF + RBV group did not complete the treatment and 9.8% (14/143) in the G/P group did not test HCV RNA after treatment completion. Adverse events (A/Es) were reported in 59.7% (569/953) and 25.9% (37/143) of the SOF + RBV and G/P groups, respectively. In the SOF + RBV group, 12 (1.26%) patients discontinued treatment owing to A/Es, whereas no patients discontinued treatment because of A/Es in the G/P group. CONCLUSION: In both treatment groups, SVR was high when treatment was completed. However, there was a high dropout rate in the SOF + RBV group, and the dropout analysis showed that these were patients with liver cirrhosis (LC; 43/285, 15.1%), especially those with decompensated LC (12/32, 37.5%). Therefore, an early initiation of antiviral therapy is recommended for a successful outcome before liver function declines. Furthermore, patients with decompensated LC who are considered candidates for SOF + RBV treatment should be carefully monitored to ensure that their treatment is completed, especially those with low hemoglobin and high alanine transaminase.

Hepatitis C virus (HCV) infection has been the leading indication for liver transplantation (LT) in the United States. Since 2013, interferon-free antiviral therapy has led to sustained virological response in many LT candidates. We compared the wait-list mortality of HCV patients with that of patients with other chronic liver diseases. Data for primary LT candidates were obtained from the Organ Procurement and Transplantation Network database. Adult wait-list registrants were divided into 3 cohorts: cohort 1 included patients on the waiting list as of January 1, 2004; cohort 2 as of January 1, 2009; and cohort 3 as of January 1, 2014. The primary outcome was wait-list mortality, and the secondary outcome was the rate of change in Model for End-Stage Liver Disease (MELD). Multivariate Cox proportional hazards analysis was performed to evaluate 12-month wait-list mortality. The cohorts included 7627 LT candidates with HCV and 13,748 patients without HCV. Compared with cohort 2, HCV patients in cohort 3 had a 21% lower risk of death (hazard ratio [HR], 0.79; 95% confidence interval [CI], 0.67-0.93). Among patients with non-HCV liver disease, no difference in mortality was seen between cohorts 2 and 3 (HR, 0.97; 95% CI, 0.86-1.09). Among HCV patients, the mean rate of change in MELD decreased from 2.35 per year for cohort 2 to 1.90 per year for cohort 3, compared with 1.90 and 1.66 in cohorts 2 and 3, respectively, among non-HCV patients. In this population-based study, wait-list mortality and progression of disease severity decreased in recent HCV patients for whom direct-acting antiviral agents were available.

OBJECTIVES: Surveillance colonoscopy is recommended after polypectomy because adenoma recurrence is common. The aim of this study was to evaluate the predictors of high-risk adenoma occurrence at surveillance colonoscopy in patients who undergo colorectal adenoma removal and to clarify the association between age and recurrent colorectal adenoma. METHODS: This retrospective study included 563 patients who had colorectal adenomas at baseline colonoscopy and who underwent surveillance colonoscopy. The risk factors for recurrent adenoma were evaluated and the 5-year cumulative incidence rates of overall and high-risk adenoma were compared according to age group. RESULTS: During a mean follow-up period of 3.1 years, 305 (54.2%) patients had overall adenoma recurrence, and 80 (14.2%) patients had high-risk adenoma at surveillance colonoscopy. In a multivariate analysis, old age (≥60 years) and presence of multiple adenomas (3 or more) were significantly associated with high-risk adenoma (p = 0.002 and p = 0.006 respectively). The 5-year cumulative incidence rates of high-risk adenoma were 7.4, 16.7, and 24.1% in the < 50, 50-59, and ≥60 years group respectively (p < 0.001). CONCLUSIONS: Old age (≥60 years) and presence of multiple adenomas (3 or more) were strongly associated with the occurrence of high-risk adenoma at surveillance colonoscopy. The 5-year cumulative incidence of high-grade adenoma was significantly high in the old age group.

BACKGROUND & AIMS: Cirrhosis from hepatitis C virus (HCV) infection is a major cause of end-stage liver disease and hepatocellular carcinoma worldwide. We determine the prevalence of cirrhosis among HCV-infected American adults including those unaware of their infection. METHODS: Using the National Health and Nutrition Examination Survey (NHANES) data, we identified participants aged ⩾20 years with detectable serum HCV RNA. The prevalence of advanced fibrosis and cirrhosis was determined for eras 1 (1988-94), 2 (1999-2006) and 3 (2007-2012) by using FIB-4 >3.25 and APRI >2.0, respectively. RESULTS: Out of 52,644 NHANES examinees, 49,429 were tested for HCV, of whom 725 met the inclusion criteria (positive HCV RNA with available data for FIB-4 and APRI). Based on APRI, 6.6% (95% confidence interval [CI]: 2.2-11.0) of HCV-infected adults in era 1, 7.6% (95% CI: 3.4-11.8) in era 2 and 17.0% (95% CI: 8.0-26.0) in era 3 had cirrhosis. In the multivariable regression analysis, this era effect was attributable to increasing age (odds ratio [OR]:1.04, 95% CI: 1.02-1.07), diabetes (OR: 2.33, 95% CI: 1.01-5.40) and obesity (OR: 2.96, 95% CI: 1.15-7.57). Cirrhosis was as common among respondents who were unaware of their infection as those who were aware (both 11%). Results were identical when FIB-4 was used. CONCLUSIONS: Among HCV-infected American adults, the proportion with cirrhosis has increased rapidly. Cirrhosis prevalence remains high in individuals unaware of their HCV infection. These data highlight the urgency for HCV screening regardless of symptoms, systematic assessment for liver fibrosis in those with HCV infection and institution of antivirals to prevent advanced liver disease. LAY SUMMARY: Chronic hepatitis C virus (HCV) infection is a major cause of cirrhosis, creating a large public health burden. Based on the U.S. National Health and Nutrition Examination Survey sample, we found the proportion of patients with cirrhosis among Americans with HCV infection increased from 6.6% to 17.0% over the past two decades. Patients who were unaware of their infection were just as likely to have cirrhosis as those who knew about their infection, which highlights the need for screening and treatment for HCV at the population level.

BACKGROUND & AIMS: Little is known about whether the antiviral agent entecavir is more effective than a less potent drug, lamivudine, in reducing the risk of death and hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. METHODS: We performed a retrospective analysis of data from 5374 consecutive adult patients with chronic hepatitis B, treated with entecavir (n = 2000) or lamivudine (n = 3374), at a tertiary referral hospital in Seoul, Korea, from November 1, 1999, through December 31, 2011. Data were collected from patients for up to 6 years and analyzed by a multivariable Cox proportional hazards model for the entire cohort and for propensity score-matched cohorts. RESULTS: During the study period, 302 patients (5.6%) died, 169 (3.1%) received a liver transplant, and 525 (9.8%) developed HCC. Multivariable analyses showed that compared with lamivudine, entecavir therapy was associated with a significantly lower risk of death or transplantation (hazard ratio [HR], 0.49; 95% confidence interval [CI], 0.38-0.64), but a similar risk of HCC (HR, 1.08; 95% CI, 0.87-1.34). In the 1792 overall propensity-matched pairs, entecavir again was associated with a significantly lower risk of death or transplantation (HR, 0.49; 95% CI, 0.37-0.64) and a similar risk of HCC (HR, 1.01; 95% CI, 0.80-1.27). Entecavir also reduced the risk of death or transplantation, compared with lamivudine, in 860 pairs of patients with cirrhosis (HR, 0.42; 95% CI, 0.31-0.57) but there were no differences in risk for HCC (HR, 1.00; 95% CI, 0.78-1.28). However, entecavir and lamivudine did not have significantly different effects on clinical outcome in 878 pairs of patients without cirrhosis. CONCLUSIONS: In a retrospective study of 5374 patients with chronic hepatitis B virus infection, entecavir therapy was associated with a significantly lower risk of death or transplantation than lamivudine. However, the drugs did not have different effects on HCC risk.

Donor lymphocyte infusion (DLI) is performed to augment an anti-tumor immune response or ensure donor stem cells remain engrafted following allogeneic stem cell transplantation but may induce graft-versus-host disease (GVHD) involving skin, intestine, and liver. Although hepatic involvement of GVHD can manifest as mild to severe hepatitis, few reports have mentioned acute severe liver dysfunction with encephalopathy. We experienced a case of acute severe liver dysfunction with semicoma after DLI in a patient with relapsed multiple myeloma following allogeneic stem cell transplantation, in whom chronic viral hepatitis B had been suppressed by antiviral treatment. The patient recovered after high-dose glucocorticoid administration based on an assessment of hepatic GVHD. Clinicians should be aware of the possibility of this catastrophic hepatic complication after DLI in hematologic disorders.

Pre-S mutation of hepatitis B virus (HBV) is known to be a risk factor for hepatocarcinogenesis. A previous study suggested that pre-S mutation(s) may associate with increased recurrence after surgical resection. In the present study, 64 patients with HBV-related hepatocellular carcinoma (HCC) were categorized into two groups according to the presence or absence of pre-S mutation(s). The clinicopathological variables of the two groups were analyzed to assess the relationship between pre-S mutations and postoperative recurrence. Nineteen patients (29.7%) had pre-S mutations;13 had a pre-S deletion, three had a pre-S2 start codon mutation, two patients had both a pre-S deletion, and a pre-S2 start codon mutation, and one patient had a pre-S2 insertion. The two groups did not differ in terms of baseline clinicopathological parameters. Cirrhosis and satellite lesion(s) were predictive factors for postoperative recurrence and poor overall survival. Recurrence-free survival (P = 0.320) and overall survival (P = 0.238) did not differ significantly when pre-S mutations were present. In conclusion, this study did not find evidence supporting the notion that pre-S mutation(s) are associated with postoperative recurrence after surgical resection.

BACKGROUND: Despite suggestions to lower the upper reference limits (URL) for aminotransferase activities to increase the detection of liver disease, there is no generally accepted URL in the general Korean population. METHODS: We set the URL for alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities at the 97.5th percentile in a population at low risk for liver disease (n=3316; negative HBs antigen, low alcohol intake, normal waist circumference, normal lipid or carbohydrate metabolism, and absence of medication use) derived from the 2007 to 2009 Korean National Health and Nutrition Examination Survey (KNHANES; n=16,608). RESULTS: The URLs for ALT activity were 53 IU/L for men and 30 IU/L for women, and the corresponding limits for AST activity were 37 IU/L for men and 29 IU/L for women. The age-adjusted prevalence of the elevated ALT activity was 8.6% [95% confidence interval (CI), 8.2%-9.1%] in the 2007 to 2009 KNHANES and 6.9% (95% CI, 6.3%-7.5%) in the 2001 KNHANES, a relative increase of 24.6% (P<0.05). This increase was concentrated among those aged 20 to 29, with a relative increase of 66.7%, and those aged 30 to 39, with a relative increase of 54.4%. There was no significant change in the prevalence of elevated AST activity. CONCLUSIONS: The URL for ALT activity among the general Korean population is clearly higher than recently proposed thresholds. The trajectory of the increasing prevalence of elevated ALT activity heralds an increased burden of chronic liver disease in the future Korean population.

GOALS AND BACKGROUND: Colonoscopy with consecutive esophagogastroduodenoscopy (CCEGD) can be more convenient than performing each procedure individually. There has been no randomized controlled trial comparing carbon dioxide (CO2) versus air insufflations during CCEGD in sedated patients. CO2 insufflation instead of air during CCEGD may reduce abdominal pain and be more comfortable. We investigated the efficacy and safety of CO2 insufflation during CCEGD in moderately sedated outpatients. STUDY: This was a randomized, double-blind, controlled trial. A total of 96 outpatients were randomly assigned to the groups of CO2 or air insufflation. Postprocedure pain was assessed using a 0 to 10 visual analogue scale, and the proportion of pain-free patients was compared between the groups. Waist circumferences and end-tidal CO2 (ETCO2) were measured. RESULTS: Among 96 patients, cecal intubation failed in 2 patients, who were excluded from the analysis. Forty-eight patients in the CO2 and 46 patients in the air group completed the study. There was significant difference between the 2 groups regarding the proportion of pain-free patients 30 minutes after the procedures [air group, 35/46 (76.1%) vs. CO2 group, 44/48 (91.6%)] (P=0.03). However, there was no significant difference in the proportion at 6 and 24 hours after the procedures. The mean increase in waist circumference was greater with air than with CO2 (1.54 vs. 0.18 cm, P<0.001). The ETCO2 measured immediately after the procedures was slightly higher in the CO2 group than in the air group (38.6 vs. 37.2 mm Hg, P=0.02), but the values were within the normal range. No significant adverse events occurred. CONCLUSIONS: CO2 insufflation during CCEGD reduced postprocedural pain and distension compared with air. It was comfortable and safe to use in moderately sedated outpatients.

GOALS AND BACKGROUND: Premedication with pronase, dimethylpolysiloxane, and sodium bicarbonate improves visibility during upper gastrointestinal (UGI) endoscopy. However, the optimal time for this combination to take effect is unknown. We investigated the optimal time of pre-UGI endoscopy medication. STUDY: A randomized, investigator-blind, controlled trial. The 300 patients who were to receive premedication were randomized into 3 groups according to the following medication time before UGI endoscopy: 10 minutes (group A, n=98), 10 to 30 minutes (group B, n=97), and 30 minutes premedication (group C, n=99). Visibility scores (range, 1 to 4, with lower scores indicating better gastric mucosal visibility) were assessed for the antrum, lower body, upper body, and fundus and compared, including the sum of the scores, between the 3 groups. RESULTS: Group B had significantly lower visibility scores for the lower body, upper body, and fundus than group C (P=0.001, 0.009, and 0.002, respectively). Group A obtained significantly lower scores for the antrum and lower body than group C (P=0.007 and 0.005, respectively). The total visibility scores of groups A and B were significantly lower compared with those of group C (P=0.001, 0.003, respectively). CONCLUSIONS: Administration of pronase, dimethylpolysiloxane, and sodium bicarbonate within 30 minutes before UGI endoscopy significantly improved endoscopic visualization. However, the optimal time to achieve the best visibility was between 10 to 30 minutes before UGI endoscopy.

BACKGROUND/AIMS: Split-dose polyethylene glycol (PEG) is a standard bowel preparation regimen for colonoscopy, but the large volume is burdensome to ingest and the night dose causes sleep disturbance. This study was performed to evaluate the efficacy and tolerability of a bowel preparation protocol using low-volume morning-only PEG with specially designed low-residue test meals (LV-PEG with TM) compared to a standard-volume split-dose PEG bowel preparation with a standard diet (SV-PEG with SD). METHODS: This was a single-center, prospective, randomized, investigator-blinded, noninferiority study. The primary end point was bowel preparation quality according to the Ottawa scale. Tolerability, compliance, adverse events, sleep quality and polyp/adenoma detection were also assessed. RESULTS: Among 197 patients analyzed (mean age 54.6 years, 51.3% men), 97 received LV-PEG with TM and 100 received SV-PEG with SD. The Ottawa score for the total colon was 3.76 ± 2.07 in the LV-PEG with TM group and 3.67 ± 1.57 in the SV-PEG with SD group (p = 0.723; difference 0.09, 95% confidence interval -0.60 to 0.42). The compliance was high (more than 95%) in both groups (p = 0.621). PEG was easier to ingest for patients in the LV-PEG with TM group compared to the SV-PEG with SD group [visual analogue scale (VAS) for difficulty: 4.64 ± 2.46 vs. 5.97 ± 2.42, respectively; p < 0.001]. Diet instructions were also easier to comply with for patients in the LV-PEG with TM group compared to the SV-PEG with SD group (VAS for difficulty: 3.11 ± 2.25 vs. 4.00 ± 2.39, respectively; p = 0.008). Patients in the LV-PEG with TM group had a lower incidence of abdominal bloating (p = 0.012) and better sleep quality (p < 0.001). There was no difference between the groups regarding polyp and adenoma detection. CONCLUSIONS: LV-PEG with TM and SV-PEG with SD have similar efficacy with regard to bowel preparation for colonoscopy. LV-PEG with TM provided easier PEG intake and diet compliance, less abdominal bloating and better sleep quality than SV-PEG with SD.

Autoimmune liver disease is an important immune-mediated pathologic entity involving the liver and intrahepatic bile duct, including autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. Although it is necessary to ascertain its presence in acute or chronic liver disease without common causes, it is not easy to diagnose this disease straightforwardly because of its rarity. Recently, the incidence and prevalence of autoimmune hepatitis and primary biliary cholangitis have increased in several regions. In contrast, there is limited data dealing with the trend of the epidemiology of primary sclerosing cholangitis worldwide. Physicians should consider the epidemiologic characteristics of autoimmune liver disease because early diagnosis and proper treatment might prevent the progression of advanced liver disease. In addition, more sophisticated epidemiologic studies will be needed to elucidate the trend of these rare diseases nationwide.

BACKGROUND: Several factors influence bowel preparation quality. Recent studies have indicated that the time interval between bowel preparation and the start of colonoscopy is also important in determining bowel preparation quality. OBJECTIVE: To evaluate the influence of the preparation-to-colonoscopy (PC) interval (the interval of time between the last polyethylene glycol dose ingestion and the start of the colonoscopy) on bowel preparation quality in the split-dose method for colonoscopy. DESIGN: Prospective observational study. SETTING: University medical center. PATIENTS: A total of 366 consecutive outpatients undergoing colonoscopy. INTERVENTION: Split-dose bowel preparation and colonoscopy. MAIN OUTCOME MEASUREMENTS: The quality of bowel preparation was assessed by using the Ottawa Bowel Preparation Scale according to the PC interval, and other factors that might influence bowel preparation quality were analyzed. RESULTS: Colonoscopies with a PC interval of 3 to 5 hours had the best bowel preparation quality score in the whole, right, mid, and rectosigmoid colon according to the Ottawa Bowel Preparation Scale. In multivariate analysis, the PC interval (odds ratio [OR] 1.85; 95% CI, 1.18-2.86), the amount of PEG ingested (OR 4.34; 95% CI, 1.08-16.66), and compliance with diet instructions (OR 2.22l 95% CI, 1.33-3.70) were significant contributors to satisfactory bowel preparation. LIMITATIONS: Nonrandomized controlled, single-center trial. CONCLUSIONS: The optimal time interval between the last dose of the agent and the start of colonoscopy is one of the important factors to determine satisfactory bowel preparation quality in split-dose polyethylene glycol bowel preparation.

BACKGROUND/AIMS: Currently, a split-dose of polyethylene glycol (PEG) is the mainstay of bowel preparation due to its tolerability, bowel-cleansing action, and safety. However, bowel preparation with PEG is suboptimal because residual fluid reduces the polyp detection rate and requires a more thorough colon inspection. The aim of our study was to demonstrate the efficacy of a sufficient dose of prokinetics on bowel cleansing together with split-dose PEG. METHODS: A prospective endoscopist-blinded study was conducted. Patients were randomly allocated to two groups: prokinetic with split-dose PEG or split-dose PEG alone. A prokinetic [100 mg itopride (Itomed)], was administered twice simultaneously with each split-dose of PEG. Bowel-cleansing efficacy was measured by endoscopists using the Ottawa scale and the segmental fluidity scale score. Each participant completed a bowel preparation survey. Mean scores from the Ottawa scale, segmental fluid scale, and rate of poor preparation were compared between both groups. RESULTS: Patients in the prokinetics with split-dose PEG group showed significantly lower total Ottawa and segmental fluid scores compared with patients in the split-dose of PEG alone group. CONCLUSION: A sufficient dose of prokinetics with a split-dose of PEG showed efficacy in bowel cleansing for morning colonoscopy, largely due to the reduction in colonic fluid.

BACKGROUND: Hepatocellular carcinoma (HCC) screening has been recommended for hepatitis B virus (HBV)-infected individuals in an effort to detect HCC at a sufficiently early stage to provide potentially curative treatments. The study reported here is the first to address the rate of HCC screening use in an HBV endemic area. METHODS: Data were collected from 11,147 adults aged ≥40 years who participated in the 2007-2009 Korea National Health and Nutrition Examination Survey and had a valid HBV surface antigen test. Current HCC screening was defined as either receiving an ultrasonography or an α-fetoprotein measurement in the past year. Prevalence estimates were weighted. RESULTS: The response rate was 78.4 %, and 436 cases of HBV infection were identified. The overall seroprevalence of the HBV surface antigen was 4.1 % [95 % confidence interval (CI) 3.9-4.4 %]. Of the 436 HBV-infected subjects, only 23.2 % (95 % CI 19.5 -27.4 %) were aware that they had been infected, and approximately 27 % (27.1 %; 95 %CI 23.2-to 31.5 %) were up to date with their HCC screening tests; more than half (52.9 %, 95 % CI 48.2-57.5) had never been screened. In a multivariate analysis that included various sociodemographic variables, only self-reported awareness of HBV infection was significantly associated with current HCC screening tests (odds ratio 2.82; 95 % CI 1.64-4.84). CONCLUSIONS: Adoption of HCC screening as a standard practice among HBV-infected Korean adults aged ≥40 years is suboptimal. Evidence-based programs in communities and education for both healthcare providers and HBV-infected persons are needed to improve the implementation of HCC screening in clinical practice.

BACKGROUND: It is unclear to what extent insulin resistance (IR) modulates the association linking obesity to alanine aminotransferase (ALT) activity elevation. METHODS: We measured the homeostatic model assessment for IR (HOMA-IR) in 1591 participants aged 12-18 years from the 2008 to 2009 Korea National Health and Nutrition Examination Survey. RESULTS: Overweight adolescents had an odds ratio of 7.23 [95% confidence interval (95% CI), 4.33-12.10] for an elevated ALT activity compared with normal-weight adolescents, and the corresponding risk was 23.62 (95% CI, 12.98-42.98) in obese adolescents. Adjustments for other participant factors did not substantially affect the results. The addition of the HOMA-IR data decreased the estimate for overweight adolescents by 27% and for obese adolescents, the decrease was 47%. Both obesity and IR markers remained independent predictors of outcome. CONCLUSIONS: The greater the obesity level, the more that IR contributes to the association between obesity and an elevated ALT activity.
