The relationship between manometric subtype and symptom details in achalasia. Esophagus 2023; 20:761-768. [PMID: 37093537 DOI: 10.1007/s10388-023-01008-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Accepted: 04/17/2023] [Indexed: 04/25/2023]
Abstract
BACKGROUND Although dysphagia and chest pain are the two most common symptoms in patients with achalasia, the mechanism of evoking symptoms is still unknown. The aim of this study was to reveal the relationship between symptoms and the subtypes of achalasia defined by the Chicago classification. METHODS A total of 71consecutive patients with newly diagnosed achalasia were enrolled between March 2009 and December 2017. Esophageal motility was assessed by high-resolution manometry (HRM) with the Chicago classification v 3.0. and esophagograms. Their symptoms were evaluated with structured self-reported questionnaires focused on dysphagia and chest pain. Symptom profiles and radiographic findings according to the manometric subtypes were investigated. RESULTS Among the total 71 patients, 69 patients (97%) had dysphagia and 39 patients (54%) had chest pain. Regarding dysphagia, type II patients reported dysphagia in the throat the most, while types I and III patients mostly felt it in the epigastrium. Type II patients often felt dysphagia at the time of swallowing (41%), but this was reported in only 8.7% of Type I and 33% of Type III patients (p = 0.02). Concerning chest pain, Type I patients rarely had pain during meals (14%), but more often while sleeping (43%) and in early morning (43%), while type III patients often had pain during meals (67%). Type III patients reported that solid food caused pain more often than other types (I/II/III 0/10/33%, p = 0.09). CONCLUSIONS Detailed symptoms of achalasia, such as its site and timing, varied by subtypes. The status of the esophageal body might induce those differences in symptoms.

Abstract
BACKGROUND Functional dyspepsia (FD) is a disorder that presents with chronic dyspepsia, which is not only very common but also highly affects quality of life of the patients. In Japan, FD became a disease name for national insurance in 2013, and has been gradually recognized, though still not satisfactory. Following the revision policy of Japanese Society of Gastroenterology (JSGE), the first version of FD guideline was revised this time. METHOD Like previously, the guideline was created by the GRADE (grading of recommendations assessment, development and evaluation) system, but this time, the questions were classified to background questions (BQs, 24 already clarified issues), future research questions (FRQs, 9 issues cannot be addressed with insufficient evidence), and 7 clinical questions that are mainly associated with treatment. RESULTS AND CONCLUSION These revised guidelines have two major features. The first is the new position of endoscopy in the flow of FD diagnosis. While endoscopy was required to all cases for diagnosis of FD, the revised guidelines specify the necessity of endoscopy only in cases where organic disease is suspected. The second feature is that the drug treatment options have been changed to reflect the latest evidence. The first-line treatment includes gastric acid-secretion inhibitors, acetylcholinesterase (AChE) inhibitors (acotiamide, a prokinetic agent), and Japanese herbal medicine (rikkunshito). The second-line treatment includes anxiolytics /antidepressant, prokinetics other than acotiamide (dopamine receptor antagonists, 5-HT4 receptor agonists), and Japanese herbal medicines other than rikkunshito. The patients not responding to these treatment regimens are regarded as refractory FD.

Utility of a new automated diagnostic program in high-resolution esophageal manometry. J Gastroenterol 2021; 56:633-639. [PMID: 33987747 DOI: 10.1007/s00535-021-01794-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 05/04/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND A new automated diagnostic program for high-resolution esophageal manometry (HREM) has been developed. This diagnostic program could detect locations of landmarks and could make final diagnoses automatically. However, the accuracy of the program is not known. The aim of this study was to evaluate the accuracy of the automated diagnostic program for HREM. METHODS A total of 445 studies were enrolled. An HREM system (Starlet®) was used, and esophageal motility was diagnosed using the Chicago classification v3.0. First, the locations of the upper esophageal sphincter, transition zone, lower esophageal sphincter, esophago-gastric junction, crural diaphragm and stomach were determined, and each swallow was checked manually. Then, the parameters of the Chicago classification were calculated using an analytic program of the Starlet, and diagnoses were made by three experts. Second, all study raw data were analyzed again by the automated diagnostic program. Diagnoses made by the program were compared to those made by experts to evaluate the accuracy of the diagnoses. RESULTS The new diagnostic program could identify the landmarks of each swallow, calculate the parameters and make a final diagnosis within 10 s. The diagnoses made by the automated diagnostic program were not matched to those made by experts in only 10 studies, and the overall accuracy of the new automated diagnostic program thus reached 97.8% (435/445). CONCLUSIONS The new automated diagnostic program for HREM is clinically useful in terms of high diagnostic accuracy and time-saving.

Impact of improvement of sleep disturbance on symptoms and quality of life in patients with functional dyspepsia. BMC Gastroenterol 2021; 21:78. [PMID: 33602148 PMCID: PMC7890897 DOI: 10.1186/s12876-021-01659-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 02/04/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND/AIMS Functional dyspepsia (FD) is often comorbid with sleep disturbance. However, it is not fully understood how sleep disturbance affects the pathophysiology of FD. We aimed to investigate the relationship between FD and sleep disturbance. METHODS We prospectively enrolled 20 FD patients with sleep disturbance between December 2018 and July 2019. Patients took sleep aids for 4 weeks and filled out questionnaires before and after taking sleep aids. Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Athens Insomnia Scale (AIS) were used to evaluate the severity of their sleep disturbance. Modified Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (mFSSG), Gastrointestinal Symptom Rating Scale (GSRS), and the Japanese version of Patient Assessment of Constipation Quality of Life (JPAC-QOL) were used to evaluate the severity of GI symptoms. Short-Form 36-Item Health Survey (SF-36) was used to evaluate QOL. Pre- and post-sleep medication values of questionnaires were compared. RESULTS Among 20 enrolled patients, 16 completed the study protocol. Zolpidem, eszopiclone, and suvorexant were administered to six, nine, and one patient, respectively. Each median total score of questionnaires (pre-/post-sleep medication, respectively) was as follows: PSQI, 10.0/8.5; ESS, 12.5/5.0; AIS, 10.0/4.0; mFSSG, 21.0/16.0; GSRS, 44.0/31.0 (Pain in GSRS, 11.0/5.0); JPAC-QOL, 26.0/15.5; SF-36, 63.9/71.9. All of these results showed statistically significant differences between pre- and post-sleep medication (p < 0.05). CONCLUSIONS Improvement of sleep disturbance by administration of sleep aids resulted in improvement of GI symptoms and QOL in patients with FD. This effect may be related to pain modification.

Abstract
BACKGROUND/AIM We evaluated the efficacy of vonoprazan (VPZ), a novel potassium-competitive acid blocker, in patients with proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease (GERD), exhibiting continued pathological esophageal acid exposure (EAE). METHODS Despite ≥8 weeks of appropriate PPI therapy, patients with -persistent reflux symptoms and pathological EAE times (EAETs ≥4%) were invited to switch to VPZ treatment. After an 8-week-course of once-daily VPZ (20 mg), multichannel intraluminal impedance-pH (MII-pH) monitoring was repeated to compare gastric acid exposure times (GAETs), EAETs, and other reflux parameters relative to the baseline values. Before each MII-pH study, reflux symptom severities were scored using the Gastrointestinal Symptom Rating Scale; erosive esophagitis and fasting plasma gastrin levels were also assessed. RESULTS From among the 124 patients undergoing MII-pH monitoring, 13 patients (median age, 69 years; females, 64%) were monitored at baseline (while on PPI therapy) and after VPZ therapy. The median GAET associated with VPZ treatment (23.8%) was less than that for PPI treatment (41.1%; p = 0.01), including both daytime and nighttime measurements. VPZ therapy resulted in better median EAET values (4.5%) than did PPI therapy (10.6%) during the 24-h monitoring period (p = 0.055). EAE normalization was achieved in 46% of VPZ-treated patients and was associated with complete gastric acid suppression (p = 0.005). After switching to VPZ, reflux symptoms (p < 0.01) and erosive esophagitis (p = 0.01) improved. CONCLUSION In patients with PPI-refractory GERD, VPZ provides more potent gastric acid suppression, more effective EAE control, enhanced symptom improvement, and better esophagitis healing than PPIs.

[PMID: 31990424 DOI: 10.1111/apt.15641] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2019] [Revised: 09/10/2019] [Accepted: 01/05/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Vonoprazan (V), a potassium-competitive acid blocker, has a more durable acid-inhibitory effect as compared with standard-dose proton pump inhibitors (PPIs) but has not been compared with 2-4 times higher daily PPI doses administered in two divided doses. AIMS To evaluate the acid-inhibitory effect of V 10/20 mg once-daily (OD; V10/V20) vs rabeprazole (R) 10/20 mg twice-daily (BID; R20/R40) in healthy Japanese volunteers. METHODS This multicentre, randomised, open-label, two-period, crossover study compared V10 or V20 vs R20, or V20 vs R40 using three cohorts of 10 healthy Japanese adults. Within each cohort, subjects were randomised to receive V or R for 7 days and, following a washout period ≥7 days, the other treatment for 7 days. On day 6 of each period, 24-hours multichannel gastric impedance-pH monitoring was performed. Percent times pH ≥ 3, ≥4 and ≥5 (pH 3, 4 and 5 holding time ratios [HTRs]) in 24 hours were evaluated as primary pharmacodynamic endpoints. RESULTS Acid-inhibitory effect (24-hours pH 3 HTR) of V20 was greater than those of R20 (91.0% vs 65.3%; P = .0049) and R40 (98.5% vs 85.9%; P = .0073). Similar results were obtained for 24-hours pH 4 and 5 HTRs. V20 also achieved greater nocturnal pH 4 (91.5% vs 73.2%; P = .0319) and 5 HTRs (78.8% vs 62.2%; P = .0325) as compared with R40. One subject (20%) developed diarrhoea while receiving R40 which was considered treatment-related. CONCLUSIONS Compared with 2-4 times the standard daily dose of R, V20 exerts a more potent and durable acid-inhibitory effect. Trial identifier: UMIN000022198 (www.umin.ac.jp/ctr/index.htm).

Clinical impact of different cut-off values in high-resolution manometry systems on diagnosing esophageal motility disorders. J Gastroenterol 2019; 54:1078-1082. [PMID: 31388756 DOI: 10.1007/s00535-019-01608-3] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Accepted: 07/31/2019] [Indexed: 02/04/2023]
Abstract
BACKGROUND The values of the parameters in the Chicago classification measured by a high-resolution manometry (HRM) system with the Unisensor catheter (Starlet) are significantly different from those measured by the ManoScan. The contraction vigor is categorized by values of the distal contractile integral (DCI) in the Chicago classification v3.0; however, reference values of the DCI in the Starlet and the clinical impact of the different reference values in the Starlet and ManoScan on diagnosing esophageal motility disorders are not known. METHODS We evaluated data from a previous report in which ManoScan and Starlet were compared in the same subjects. The DCI values in each system were compared and reference DCI values were calculated. Moreover, diagnoses assessed by Starlet using reference values in ManoScan were compared with those using calculated reference values and those assessed by ManoScan. RESULTS There was a significant positive correlation between the DCI values measured by ManoScan and those measured by Starlet (r = 0.80, p < 0.01). Based on a linear functional relationship considering measurement errors, the reference DCI values for diagnosing failed, weak and hypercontractile contraction vigor were calculated as 590.6, 1011.3 and 10,085.8 mmHg-s-cm, respectively, in the Starlet. Therefore, the proposed reference values in the Starlet were 500, 1000 and 10,000 mmHg-s-cm, respectively. When the reference values in the ManoScan were used in the Starlet data, approximately 30% of subjects were diagnosed inappropriately. This issue was resolved using the proposed reference values in the Starlet. CONCLUSION Recognizing systemic differences in HRM systems is important.

Abstract
BACKGROUND Esophageal motility abnormalities (EMAs) and interstitial lung diseases (ILDs) are often seen in patients with systemic sclerosis (SSc). Gastroesophageal reflux disease (GERD) could be associated with ILDs, but it is not fully understood if ILDs are caused by GERD or SSc itself. METHODS A total of 109 patients with SSc who underwent high-resolution manometry were enrolled. Esophageal motility was diagnosed with the Chicago classification v3.0. The severity of skin thickness was evaluated by the modified Rodnan total skin thickness score (mRSS). The severity of ILDs was assessed with the chest high-resolution computer tomography (HRCT) scoring system. Relationships between EMAs, GERD, autoantibodies, skin thickness and ILDs were evaluated. RESULTS 44 patients had normal esophageal motility, eight had esophago-gastric junction outflow obstruction, one had distal esophageal spasm, 27 had ineffective esophageal motility and 29 had absent contractility (AC). Patients with AC had more GERD than those with normal esophageal motility (p < 0.05). The mRSS score in patients with AC was significantly higher than that in those with normal esophageal motility (p < 0.05). The HRCT score in patients with AC tended to be higher than that in those with normal esophageal motility (p = 0.05). A multivariable analysis showed that severe skin thickness was a significant predictor of AC. GERD was not a significant predictor for ILDs. CONCLUSIONS There were significant correlations between EMAs and severe skin thickness. GERD is not an etiology of ILDs.

Abstract
We herein report a unique case of hepatitis C virus (HCV)-associated renal disease without cryoglobulinemia that showed proteinuria, hypoproteinemia, ascites, and edema. Due to combination therapy with daclatasvir and asunaprevir, the patient achieved sustained virological response at week 24 of the therapy. Furthermore, the therapy caused marked amelioration of her proteinuria, ascites, edema, and hypoalbuminemia, and finally improved her estimated glomerular filtration rate. There were no adverse events, and the combination therapy was well-tolerated. We recommend that HCV eradication with antiviral therapy using direct-acting antiviral agents be attempted first for all renal disease with HCV infection, regardless of cryoglobulinemia, considering the existence of resistance-associated variants.

Abstract
BACKGROUND Functional dyspepsia (FD), a heterogeneous disorder, involves multiple pathogenetic mechanisms. Developing treatments for FD has been challenging. We performed a randomized, placebo-controlled, double-blind clinical trial to determine the efficacy of rikkunshito, a Japanese herbal medicine, in FD patients. METHODS FD patients (n = 192) who met the Rome III criteria without Helicobacter pylori infection, predominant heartburn, and depression were enrolled at 56 hospitals in Japan. After 2 weeks of single-blind placebo treatment, 128 patients with continuous symptoms were randomly assigned to 8 weeks of rikkunshito (n = 64) or placebo (n = 61). The primary efficacy endpoint was global assessment of overall treatment efficacy (OTE). The secondary efficacy endpoints were improvements in upper gastrointestinal symptoms evaluated by the Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index (PAGI-SYM), the Global Overall Symptom scale (GOS), and the modified Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (m-FSSG), and psychological symptoms evaluated by the Hospital Anxiety and Depression Scale (HADS). KEY RESULTS Rikkunshito increased OTE compared to placebo at 8 weeks (P = .019). Rikkunshito improved upper gastrointestinal symptoms (PAGI-SYM, GOS, and m-FSSG) at 8 weeks, especially postprandial fullness/early satiety (P = .015 and P = .001) and bloating (P = .007 and P = .002) of the PAGI-SYM subscales at 4 weeks and 8 weeks. Improvement of HADS at 8 weeks (P = .027) correlated with those of PAGI-SYM (r = .302, P = .001), GOS (r = .186, P = .044), and m-FSSG (r = .462, P < .001), postprandial fullness/early satiety (r = .226, P = .014), dyspepsia (r = .215, P = .019), and PDS (r = .221, P = .016). CONCLUSION & INFERENCES Rikkunshito may be beneficial for FD patients to simultaneously treat gastrointestinal and psychological symptoms.

Abstract
BACKGROUND The metabolism of many proton pump inhibitors is influenced by CYP2C19 genotype, which is a limitation of their use. OBJECTIVES To determine the efficacy and safety profile of Z-215 (azeloprazole sodium) as initial treatment for reflux esophagitis (RE), dose response, and optimal dose compared with rabeprazole sodium (RPZ). METHODS We conducted an exploratory, multicenter, randomized, double-blind, parallel-group study in Japan. Patients with RE aged ≥20 years were enrolled and randomly assigned to receive 10, 20, or 40 mg Z-215 or 10 mg RPZ (1:1:1:1), and orally administered the respective drug for 8 weeks. The primary efficacy end point was the endoscopic healing rate after 8 weeks of treatment (at Week 8). We also assessed the effects of CYP2C19 genotype. Safety end points were the incidence of adverse events and adverse drug reactions. RESULTS Five hundred three patients received the study drugs (10 mg Z-215: 125 patients, 20 mg Z-215: 126 patients, 40 mg Z-215: 126 patients, and 10 mg RPZ: 126 patients). The endoscopic healing rate at Week 8 was above 95% in all groups (10 mg Z-215: 95.2%, 20 mg Z-215: 96.8%, 40 mg Z-215: 95.2%, and 10 mg RPZ: 96.8%). The endoscopic healing rate and serum gastrin levels of the Z-215 groups were not influenced by CYP2C19 genotype. In patients with Grade C/D, the endoscopic healing rate at Week 4 was slightly higher in the 40-mg Z-215 group compared with the other groups. Incidences of adverse events/adverse drug reactions did not markedly differ between the Z-215 and 10-mg RPZ groups. CONCLUSIONS Z-215 was as effective and well tolerated as 10 mg RPZ in the treatment of RE in this selected population. CYP2C19 genotype status may not influence the efficacy and safety of Z-215. There were no clear dose-response effects between Z-215 doses in the endoscopic healing of RE. These findings suggest that Z-215 may be 1 option for the initial treatment of RE. ClinicalTrials.gov identifier: NCT 02463643.

Abstract
BACKGROUND AND AIM Gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) often coexist or overlap. In this study, the efficacy of acotiamide in combination with a standard dose of rabeprazole for GERD and FD was compared with that of a double dose of rabeprazole. METHODS Patients with overlap between GERD and FD experiencing heartburn and epigastric fullness symptoms after standard-dose proton pump inhibitor (PPI) for ≥ 8 weeks were randomized into two groups and received either acotiamide 300 mg/day + rabeprazole 10 mg/day or rabeprazole 20 mg/day for 4 weeks. Efficacy was assessed by reductions in symptom scores using the Izumo scale questionnaire and modified F-scale questionnaire. RESULTS As the primary endpoint, three upper gastrointestinal symptoms (heartburn, epigastralgia, and epigastric fullness) were reduced by ≥ 50% in 40.8% and 46.9% of patients in the combination and PPI double-dose groups, respectively, with no significant difference between the two groups. Essentially similar results were obtained for the modified F-scale questionnaire. No serious adverse events were noted. CONCLUSIONS Acotiamide 300 mg/day in combination with rabeprazole 10 mg/day or rabeprazole 20 mg/day relieved symptoms in patients with overlap between GERD and FD experiencing heartburn and epigastric fullness symptoms after standard-dose PPI for ≥ 8 weeks, and the efficacies did not differ between the two treatments. The combination therapy may be an alternative option for persistent symptoms in these patients.

Elevated serum uric acid level was a notable adverse event during combination therapy with sofosbuvir and ribavirin. Hepatol Res 2018; 48:E347-E353. [PMID: 28834004 DOI: 10.1111/hepr.12971] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2016] [Revised: 05/10/2017] [Accepted: 08/14/2017] [Indexed: 02/08/2023]
Abstract
AIM Combination therapy with sofosbuvir and ribavirin (SOF/RBV) has been recently available for chronic hepatitis C patients with genotype 2 (CHG2) in Japan. The domestic phase III clinical trial showed a high antiviral effect with a relatively safe adverse event (AE) profile. Our aim was to report an important AE detected during treatment. METHODS A prospective multi-institutional study of 12-week combination therapy with SOF/RBV for CHG2 was carried out to evaluate efficacy and safety. RESULTS The eligible subjects included 142 patients. Out of 50 assessable patients, 16% of the patients were diagnosed with hyperuricemia. The proportions of subjects with grade 1, grade 3, and grade 4 hyperuricemia were 12, 2, and 2%, respectively. Serum uric acid (UA) levels at week 1 of the therapy (W1) were numerically the highest during therapy in patients with hyperuricemia, and the ratio of W1/baseline serum UA levels was significantly higher than that of post-treatment week 4 or 8/baseline serum UA levels in assessable patients. Serum UA levels at W1 were significantly correlated with body mass index. The difference between serum UA levels at W1 and baseline serum UA levels was significantly correlated with the difference between serum creatinine levels at W1 and baseline serum creatinine levels. CONCLUSIONS Elevated serum UA level was a notable AE associated with SOF/RBV therapy for CHG2. However, because of the small number of subjects, the exact frequency of AEs should be re-evaluated with larger cohorts. We need to remember that elevated serum UA level might develop during the therapy, especially at W1.

Efficacy and safety of twice-daily rabeprazole maintenance therapy for patients with reflux esophagitis refractory to standard once-daily proton pump inhibitor: the Japan-based EXTEND study. J Gastroenterol 2018; 53:834-844. [PMID: 29188387 PMCID: PMC6006226 DOI: 10.1007/s00535-017-1417-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2017] [Accepted: 11/17/2017] [Indexed: 02/04/2023]
Abstract
BACKGROUND Rabeprazole at 10 or 20 mg twice daily (b.i.d.) has been reported to be highly effective in the treatment of proton pump inhibitor (PPI)-resistant reflux esophagitis (RE) that is refractory to the standard once-daily PPI regimen. We evaluated the efficacy and safety of rabeprazole maintenance therapy at 10 mg once daily (q.d.) or b.i.d. for longer than 8 weeks. METHODS Patients with RE refractory to standard PPI regimens for at least 8 weeks were enrolled. They were treated with rabeprazole at 10 or 20 mg b.i.d. for 8 weeks during the open-label treatment period. After endoscopic examination, those with confirmed healing entered the subsequent double-blind maintenance therapy. During this period, the subjects were randomized to receive rabeprazole 10 mg q.d. (control) or 10 mg b.i.d. The primary endpoint was the endoscopic no-recurrence rate at Week 52. RESULTS In total, 517 subjects entered the treatment, and 359 subjects continued on maintenance therapy. The full analysis set for central assessment included 343 subjects. The no-recurrence rate at Week 52 was significantly higher in the b.i.d. group (73.9%; p < 0.001, χ2 test) than in the q.d. group (44.8%). In particular, the b.i.d. regimen was more effective in all subgroups with Los Angeles Classification Grade B to D at treatment entry. CONCLUSIONS In the maintenance treatment of PPI-resistant RE, rabeprazole at 10 mg b.i.d. exerted a stronger recurrence-preventing effect than 10 mg q.d. over 52 weeks. No particular safety issues were noted during long-term administration. ClinicalTrials.gov number: NCT02135107.

Abstract
BACKGROUND The aim of this study was to evaluate the differences in upper gastrointestinal symptoms between generations and genders in relatively healthy Japanese subjects. METHODS Altogether, 4086 healthy Japanese male and female (M/F) adults (M/F: 2244/1842) were analyzed. Among them, 3505 subjects (M/F: 1922/1583) were underwent a routine medical checkup at one of five hospitals in Saga, Japan from January 2013 to December 2013. The others were 581 (M/F: 322/259) healthy young volunteers at the Saga Medical School from April 2007 to March 2013. The participants were asked to complete the frequency scale for the symptoms of gastroesophageal reflex disease (FSSG) questionnaire, undergo upper gastrointestinal endoscopy, and submit to a rapid urease test to diagnose Helicobacter pylori infection. Among the 4086 subjects, the 2414 who had no H. pylori infection and no positive endoscopic findings were enrolled in the study. RESULTS Subjects' average age was 46.9 ± 12.2 years, with males' and females' ages being almost equivalent. The total FSSG score were high in females compared to males (P < 0.01) and decreased significantly with aging (P < 0.05). Among the generations, FSSG scores were the highest for those 20-29 years old, and they were significantly decreased with ageing in both males and females (P < 0.05). CONCLUSION The FSSG score was significantly higher in healthy Japanese females than in males, and the scores decreased with aging.

Spontaneous remission of hepatitis B virus reactivation during direct-acting antiviral agent-based therapy for chronic hepatitis C. Hepatol Res 2017; 47:1346-1353. [PMID: 28422376 DOI: 10.1111/hepr.12905] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2017] [Revised: 04/06/2017] [Accepted: 04/13/2017] [Indexed: 02/08/2023]
Abstract
The administration of direct-acting antiviral agents (DAAs) to treat hepatitis C virus (HCV) infection has been reported to cause hepatitis B virus (HBV) reactivation. However, the actual conditions of HBV reactivation and the ideal timing of medical intervention have not been fully evaluated. We report the cases of two female patients dually infected with HBV and HCV. Both patients were inactive HBV carriers. Although the serum HCV RNA levels promptly decreased after the initiation of DAA-based therapy, the serum HBV DNA levels gradually increased during DAA-based therapy, with the peak serum HBV DNA levels observed at 16 weeks after the initiation of DAA-based therapy in both cases. Subsequently, we checked the serum HBV DNA levels closely every week several times. Fortunately, the serum HBV DNA levels gradually decreased without medical intervention. Neither case developed an alanine aminotransferase flare-up. The HCV genotypes were 2a and 1b, and the DAA-based therapies of Cases 1 and 2 were 12 weeks of sofosbuvir/ribavirin and ombitasvir/paritaprevir/ritonavir, respectively. The significance of our case reports is the demonstration of the existence of spontaneous remission of HBV reactivation that developed during DAA-based therapy, the avoidance of intervention of nucleot(s)ide analogs by frequent monitoring of serum HBV DNA levels, and development of HBV reactivation regardless of the viral genotype or class of DAA. In conclusion, the close monitoring of serum HBV DNA levels during and after DAA-based therapy is essential and medical intervention for HBV reactivation should be carefully considered on an individual basis.

Abstract
We previously reported that cascade stomach was associated with reflux symptoms and esophagitis. Delayed gastric emptying has been believed to initiate transient lower esophageal sphincter relaxation (TLESR). We hypothesized that cascade stomach may be associated with frequent TLESR with delayed gastric emptying. Eleven subjects with cascade stomach and 11 subjects without cascade stomach were enrolled. Postprandial gastroesophageal manometry and gastric emptying using a continuous 13C breath system were measured simultaneously after a liquid test meal. TLESR events were counted in early period (0-60 min), late period (60-120 min), and total monitoring period. Three parameters of gastric emptying were calculated: the half emptying time, lag time, and gastric emptying coefficient. The median frequency of TLESR events in the cascade stomach and non-cascade stomach groups was 6.0 (median), 4.6 (interquartile range) vs 5.0, 3.0 in the early period, 5.0, 3.2 vs 3.0, 1.8 in the late period, and 10.0, 6.2 vs 8.0, 5.0 in the total monitoring period. TLESR events were significantly more frequent in the cascade stomach group during the late and total monitoring periods. In contrast, gastric emptying parameters showed no significant differences between the two groups. We concluded that TLESR events were significantly more frequent in persons with cascade stomach without delayed gastric emptying.

Abstract
AIM To evaluate the clinical and virological features of acute hepatitis E (AH-E) in Gunma prefecture and focus on the hepatitis E virus (HEV) infection in immunocompromised patients. METHODS A total of 30 patients with AH-E diagnosed at our Gunma University Hospital, and located in 3-39-15 Showa-machi, Maebashi, Gunma 371-8511 Japan, and its affiliated hospitals from 2004 to 2015, were studied. We evaluated the detailed medical histories, laboratory examinations and virological features of these participants. RESULTS Of the 30 patients, 21 patients were men, with a median age of 61 years. Three of these patients had a history of recent oversea travel. A total of 14 patients had eaten raw or undercooked meat/viscera from animals, and two patients had contracted transfusion-transmitted AH-E. Eight patients were immunocompromised, including those with hematological disease, cancer receiving systemic chemotherapy and kidney transplant or connective tissue disease undergoing immunosuppressive medications. The alanine aminotransferase and total bilirubin levels were more significantly reduced in these immunocompromised patients than in the non-immunocompromised patients. Severe thrombocytopenia, an extra-hepatic manifestation of AH-E, occurred in one case. Among the 22 HEV strains whose subgenotype was determined, two were imported strains (1a and 1f), and 11 strains formed four distinct phylogenetic clusters within subgenotype 3b. The remaining nine strains differed from each other by 9.8-22.4%, and were classified into four subgenotypes (3a, 3b, 3e and 3f). CONCLUSION Markedly divergent HEV strains (3a, 3b, 3e and 3f) were found to circulate in Gunma. Although immunosuppression appears to play a crucial role in establishing chronic sequels, AH-E in eight immunocompromised patients, including transfusion-transmitted HEV infection in two patients, did not become chronic.

Abstract
Hepatitis C virus (HCV) infection is common in dialysis patients worldwide and nosocomial HCV spread within dialysis facilities continues to develop. Combination therapy with daclatasvir and asunaprevir (DCV/ASV) that has proven efficacy for dialysis patients infected with genotype 1b HCV (HCV/1b) has several concerns in Japan. The recently available combination therapy with ombitasvir, paritaprevir, and ritonavir (OBV/PTV/r) is not contraindicated in patients with chronic renal failure and has more safety profile and shorter treatment period than that with DCV/ASV. We evaluated the effects of combination therapy with OBV/PTV/r in four dialysis patients infected with HCV/1b, who were eligible for our study. On-treatment assessments included standard laboratory testing, serum HCV RNA and symptom-directed physical examinations. Three patients had a sustained virological response at 12 weeks after treatment, but one remaining patient had viral breakthrough. Notably, the patient with viral breakthrough had been coinfected with HCV/1b and HCV/2b; namely, HCV/2b with resistance-associated variations was not eradicated by the combination therapy. Among the three patients responsive to the combination therapy, one patient complained of appetite loss and itching, while in another patient the therapy was discontinued due to itching, exacerbation of wamble, and a falling tendency probably due to interaction with valsartan. These AEs were ameliorated or disappeared after the completion of the therapy. The significance of our study is persuasive virological evaluation associated to the combination therapy and reasonable interpretation of AEs. In conclusion, combination therapy with OBV/PTV/r may have promise as an efficacious therapy, but caution regarding AEs should be practiced.

Abstract
BACKGROUND/AIMS This study aimed at (i) clarifying the factors associated with high scores on the modified frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) among 3,505 relatively healthy subjects undergoing routine medical health checkups with gastrointestinal endoscopy and (ii) comparing risk factors for high FSSG scores between subjects with and without reflux esophagitis. METHODS In total, 3,505 subjects (male/female: 1,922/1,583) who underwent upper gastrointestinal endoscopy during health medical checkups at 5 hospitals in Saga, Japan from January 2013 to December 2013 were enrolled. All subjects completed a modified FSSG questionnaire, which comprised 7 questions regarding reflux symptoms and 7 questions regarding acid-related dyspepsia. Each question was assigned a score based on the frequency of symptoms. RESULTS Younger age, female gender, hiatal herniation, and endoscopic reflux esophagitis were risk factors for a FSSG score with a high total. Subjects with high scores but without esophagitis were women, and hiatal herniation and Barrett's esophagus were frequently seen in patients with reflux esophagitis. CONCLUSION Younger age, female gender, hiatal hernia, and endoscopic esophagitis were risk factors for a high FSSG score, and women tended to complain of upper gastrointestinal symptoms more frequently than did men among subjects without endoscopic esophagitis.

Abstract
BACKGROUND We recently demonstrated that cascade stomach detected by barium studies was correlated with upper gastrointestinal symptoms. We developed a new endoscopic classification of cascade stomach and examined its relationship with reflux esophagitis. METHODS Study 1: the classification (grades 0-3) was based on detecting a ridge that runs from the cardia toward the anterior wall crossing the greater curvature. Inter-observer variation was evaluated by kappa statistics when ten experienced endoscopists used this classification three times each. Study 2: in 710 consecutive subjects (500 men and 210 women) undergoing endoscopic screening, the grade of cascade stomach and incidence of reflux esophagitis were compared. RESULTS In study 1, the kappa values at the third assessment were 0.85, 0.58, 0.50, and 0.78 for each grade, respectively, while overall agreement was 0.68. In study 2, the incidence of reflux esophagitis in men was 20 % in grade 0, 17 % in grade 1, 25 % in grade 2, and 30 % in grade 3, showing significant differences. Among women, the incidence of reflux esophagitis in each grade was 9, 3, 6, and 35 %, respectively, also showing significant differences. Multivariate analysis showed that independent risk factors for reflux esophagitis were cascade stomach (odds ratio = 2.20), body mass index, and hiatus hernia in men, as well as cascade stomach (odds ratio = 9.01) and smoking tobacco in women. CONCLUSIONS This endoscopic classification of cascade stomach showed acceptable inter-observer variation. Cascade stomach is a risk factor for reflux esophagitis.

Abstract
A 44-year-old woman with multiple sclerosis (MS) receiving interferon (IFN)-beta-1a treatment was admitted to a local hospital for severe icterus and liver injury. She was transferred to our university hospital because fulminant hepatitis (FH) was suspected. She was diagnosed with acute-type FH based on hepatic coma, severe liver injury and liver failure, and she received plasma exchange and continuous hemodiafiltration therapy. On hospital day 6, she died from liver failure despite intensive care. An autopsy revealed histological findings consistent with FH. Physicians should monitor the hepatic function of MS patients receiving IFN-beta-1a treatment, as serious events can occur in rare cases.

Abstract
Objective To investigate the effect of twice-daily rabeprazole doses on health-related quality of life in refractory patients. Methods and Patients Reflux esophagitis patients with an insufficient response to once-daily proton pump inhibitor therapy (Los Angeles Classification grade A-D) received rabeprazole 10 mg or 20 mg twice daily for 8 weeks. The health-related quality of life (SF-8™) and symptoms, using the Frequency Scale for the Symptoms of Gastroesophageal reflux disease, were evaluated before treatment and at weeks 4 and 8. Endoscopy was performed at baseline and at weeks 8 and 32 where possible. The rabeprazole dose was determined by the attending physician. Results There were 1,796 patients analyzed for the efficacy of the twice-daily treatment. Of these cases, 1,462 were treated with rabeprazole 10 mg twice daily, and 334 were treated with rabeprazole 20 mg twice daily. The factors that affected the selection of the twice-daily rabeprazole dose by physicians were evaluated, and as expected, "endoscopic findings when treatment was started" had a strong effect on the selection of the rabeprazole dose. With both regimens, health-related quality of life and subjective symptoms were significantly improved at weeks 4 and 8 compared to baseline (p<0.001). The recurrence rate of erosive esophagitis at week 32 was 9.7% in rabeprazole twice daily-treated patients and 28.4% in proton pump inhibitor (PPI) once daily-treated patients. Both regimens were well tolerated. Conclusion Twice-daily treatment with rabeprazole improved the subjective symptoms and health-related quality of life in patients with refractory reflux esophagitis more effectively than the standard once-daily dose.

Abstract
Balloon-occluded retrograde transvenous obliteration (BRTO) is widely used to treat isolated gastric varices (IGVs) in Japan. However, BRTO is difficult to perform for IGVs with many small collateral veins, and no secondary treatment has been established. We herein report a rare case of IGVs refractory to BRTO successfully treated by shunt-occluded endoscopic injection sclerotherapy (SO-EIS), which is a combination therapy of major shunt occlusion by a balloon catheter and endoscopic injection sclerotherapy. Since SO-EIS can be performed regardless of the IGVs' anatomical configuration, it may be a promising alternative treatment for IGVs refractory to BRTO.

Abstract
Background/Aims Twenty-four-hour esophageal impedance and pH monitoring allows detection of all types of reflux episodes and is considered the best technique for identifying gastroesophageal refluxes. However, normative data for the Japanese population are lacking. This multicenter study aimed to establish the normal range of 24-hour esophageal impedance and pH data both in the distal and the proximal esophagus in Japanese subjects. Methods Forty-two healthy volunteers (25 men and 17 women) with a mean ± standard deviation age of 33.3 ± 12.4 years (range: 22–72 years) underwent a combined 24-hour esophageal impedance and pH monitoring. According to the physical and pH properties, distal or proximal esophageal reflux events were categorized. Results Median 45 reflux events occurred in 24 hours, and the 95th percentile was 85 events. Unlike previous reports, liquid-containing reflux events are median 25/24 hours with the 95th percentile of 62/24 hours. Acidic reflux events were median 11/24 hours with the 95th percentile of 39/24 hours. Non-acidic gas reflux events were median 15/24 hours with the 95th percentile of 39/24 hours. Proximal reflux events accounted for 80% of the total reflux events and were mainly non-acidic gas refluxes. About 19% of liquid and mixed refluxes reached the proximal esophagus. Conclusions Unlike previous studies, liquid-containing and acidic reflux events may be less frequent in the Japanese population. Non-acidic gas reflux events may be frequent and a cause of frequent proximal reflux events. This study provides important normative data for 24-hour impedance and pH monitoring in both the distal and the proximal esophagus in the Japanese population.

Abstract
As an increase in gastroesophageal reflux disease (GERD) has been reported in Japan, and public interest in GERD has been increasing, the Japanese Society of Gastroenterology published the Evidence-based Clinical Practice Guidelines for GERD (1st edition) in 2009. Six years have passed since its publication, and there have been a large number of reports in Japan concerning the epidemiology, pathophysiology, treatment, and Barrett's esophagus during this period. By incorporating the contents of these reports, the guidelines were completely revised, and a new edition was published in October 2015. The revised edition consists of eight items: epidemiology, pathophysiology, diagnosis, internal treatment, surgical treatment, esophagitis after surgery of the upper gastrointestinal tract, extraesophageal symptoms, and Barrett's esophagus. This paper summarizes these guidelines, particularly the parts related to the treatment for GERD. In the present revision, aggressive proton pump inhibitor (PPI) maintenance therapy is recommended for severe erosive GERD, and on-demand therapy or continuous maintenance therapy is recommended for mild erosive GERD or PPI-responsive non-erosive GERD. Moreover, PPI-resistant GERD (insufficient symptomatic improvement and/or esophageal mucosal break persisting despite the administration of PPI at a standard dose for 8 weeks) is defined, and a standard-dose PPI twice a day, change in PPI, change in the PPI timing of dosing, addition of a prokinetic drug, addition of rikkunshito (traditional Japanese herbal medicine), and addition of histamine H2-receptor antagonist are recommended for its treatment. If no improvement is observed even after these treatments, pathophysiological evaluation with esophageal impedance-pH monitoring or esophageal manometry at an expert facility for diseases of the esophagus is recommended.

[24-hour esophageal multichannel intraluminal impedance and pH monitoring]. NIHON RINSHO. JAPANESE JOURNAL OF CLINICAL MEDICINE 2016; 74:1285-1292.

Abstract
Monitoring of esophageal impedance is a technique for determining the physical characteris- tics (liquid, gas, or mixed) of refluxate, while impedance monitoring combined with pH recording makes it possible to assess the acidity of reflux(acid or non-acid). Assessment is usually performed by the total acid exposure time (%time pH< 4) and symptom-reflux asso- ciations including acidic and non-acidic reflux. This monitoring is quite useful for evaluation of proton pump inhibitor-resistant gastroesophageal reflux disease or non-erosive reflux disease. When normal acid exposure time and significant symptom-reflux associations are observed, a patient should be diagnosed as having hypersensitive esophagus. When normal acid exposure time and no significant symptom-reflux associations are observed, a patient should be diagnosed as having functional heartburn. Therefore, the result makes it possible to decide treatment strategy.

Faecal lactoferrin is a useful biomarker for mucosal healing in patients with ulcerative colitis during granulocyte and monocyte adsorptive apheresis therapy. Colorectal Dis 2016; 18:696-702. [PMID: 26748553 DOI: 10.1111/codi.13258] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2015] [Accepted: 11/07/2015] [Indexed: 12/13/2022]
Abstract
AIM The study investigated the value of faecal lactoferrin as a follow-up biomarker for mucosal healing of ulcerative colitis during granulocyte and monocyte adsorptive apheresis (GMA) therapy. METHOD Patients with ulcerative colitis exhibiting a moderate or severe disease activity with a partial Mayo Score (pMS) of over 4 were enrolled in this study. The patients received 10 courses of GMA therapy. The pMS value and faecal lactoferrin level were monitored and compared with the findings of endoscopy until 12 months after the last dose of GMA therapy. RESULTS Twenty patients (male:female 11:9) were enrolled in this study. Twelve had total colitis, while six had left-sided involvement and two had distal proctitis. Thirteen (65.0%) responded to GMA therapy. The faecal lactoferrin levels were significantly decreased in patients who responded to GMA therapy (P < 0.05), whereas the levels did not change in non-responders. Moreover, the faecal lactoferrin levels correlated with the endoscopic findings (r = 0.792, P < 0.01) and pMS scores (r = 0.529, P < 0.01). The correlation coefficients between the faecal lactoferrin levels and mucosal findings were higher than those observed between the pMS score and mucosal findings. CONCLUSION The faecal lactoferrin level is a useful biomarker of the mucosal findings in ulcerative colitis. Although endoscopy is the gold standard, the faecal lactoferrin level can be used as a biomarker during GMA therapy in patients with ulcerative colitis.

Abstract
Background/Aims Upper gastrointestinal symptoms are more frequent and severe in female than in male outpatients in Japan. This study compared the upper gastrointestinal symptoms between healthy male and female young adult volunteers using a questionnaire. Methods In total, 581 third-grade medical students at Saga Medical School aged 22 to 30 years underwent upper gastrointestinal endoscopy and completed a questionnaire (frequency scale for symptoms of gastroesophageal reflux disease) from 2007 to 2013. Of these 581 students, 298 who were negative for Helicobacter pylori infection and had no particular lesions on endoscopic examination were enrolled in the present evaluation. A symptom was defined as positive when the subject evaluated the frequency of the symptom as sometimes, often, or always. Results The subjects comprised of 163 males (average age, 23.7 years) and 135 females (average age, 23.1 years). Upper gastrointestinal symptoms were more frequent in the females (75 of 135, 55.6%) than males (69 of 163, 42.3%; P < 0.05), with a high score for 4 symptoms (bloated stomach, heavy feeling in the stomach after meals, subconscious rubbing of the chest with the hand, and feeling of fullness while eating meals). Of the 144 subjects (69 males and 75 females) who complained of these symptoms, the females complained of dysmotility symptoms more often than did the males, but this was not true for reflux symptoms. Conclusions This study suggests that females develop upper gastrointestinal symptoms more frequently than do males among the young healthy Japanese population.

Abstract
The standard antiviral therapy for dialysis patients infected with hepatitis C virus (HCV) is (pegylated) interferon monotherapy, but its efficacy is insufficient. Oral direct-acting antiviral agents (DAAs) have recently been developed for chronic hepatitis C patients. However, some DAAs have contraindications for chronic renal failure (CRF). Daclatasvir and asunaprevir are metabolized largely in the liver and are not contraindicated in CRF. Combination therapy with daclatasvir and asunaprevir was used for 4 dialysis patients infected with genotype 1b HCV. One patient had viral breakthrough, and the 3 others had sustained virological response 12. One patient was admitted for heart failure and percutaneous coronary intervention due to concomitant ischemic disease. Heart failure was unlikely to be caused by the combination therapy, as it was probably due to water overload. The patient continued to receive the combination therapy after the remission of the heart failure. The combination therapy was well tolerated in the other patients.

Prevalence of nonalcoholic steatohepatitis in Japanese patients with morbid obesity undergoing bariatric surgery. J Gastroenterol 2016; 51:281-9. [PMID: 26314837 DOI: 10.1007/s00535-015-1114-8] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2015] [Accepted: 08/03/2015] [Indexed: 02/04/2023]
Abstract
BACKGROUND Patients with morbid obesity selected for bariatric surgery have a high prevalence of nonalcoholic steatohepatitis (NASH); however, the incidence is varied and depends on race. The prevalence of NASH in obese Japanese patients is unknown. We evaluated the prevalence of NASH in a prospective cohort of Japanese patients with morbid obesity. METHODS From October 2009 to July 2011, consecutive patients requiring bariatric surgery underwent a liver biopsy during the operation. The indications for bariatric surgery followed the guidelines of the Asia-Pacific Metabolic and Bariatric Surgery Society. RESULTS One hundred two patients (55 males and 47 females, age 42.7 ± 10.7 years) were analyzed. The mean body mass index was 42.1 ± 8.2 kg/m(2). Among the 102 patients, 84 patients (82.4%) had nonalcoholic fatty liver disease and 79 patients (77.5%) had NASH. The grading and staging of NASH by Brunt's classification were as follows: grade 0 steatosis, one patient; grade 1 steatosis, 35 patients; grade 2 steatosis, 32 patients; grade 3 steatosis, 11 patients; stage 1 fibrosis, 25 patients; stage 2 fibrosis, 38 patients; stage 3 fibrosis, 16 patients, stage 4 fibrosis, no patients. The body weight, waist-hip ratio, visceral fat area, and aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase, fasting plasma glucose, fasting plasma insulin, C peptide, hemoglobin A1c, and homeostasis model assessment insulin resistance levels were significantly elevated in the NASH group in comparison with the non-NASH group. The platelet count was significantly decreased in the NASH group. The waist-hip ratio and the alanine aminotransferase, fasting plasma glucose, and homeostasis model assessment insulin resistance levels were found to be independent predictors of NASH in a multivariate analysis. CONCLUSION The prevalence of NASH was 77.5% in this prospective Japanese cohort. The prevalence of NASH in Japanese morbidly obese patients was extremely high, and early intervention should be undertaken.

Endoscopic treatment for esophageal varices complicated by Isaacs' syndrome involving difficulty with conventional sedation. Clin J Gastroenterol 2016; 9:27-31.

Abstract
A 54-year-old male consulted a local doctor with a chief complaint of systemic convulsions and muscle stiffness and was diagnosed with Isaacs' syndrome based on positive findings for antibodies against voltage-gated potassium channels in 2009. He subsequently experienced repeated hematemesis in 2013, at which time he was taken to our hospital by ambulance. Emergent endoscopy revealed esophageal varices with spurting bleeding. The bleeding was stopped with urgent endoscopic variceal ligation. Three days later, the patient developed sudden dyspnea with stridor during inspiration under sedation with an intravenous injection of low-dose flunitrazepam prior to receiving additional treatment and was aroused with intravenous flumazenil, after which his dyspnea immediately improved. Dyspnea may be induced by muscle cramps associated with Isaacs' syndrome exacerbated by sedation. Endoscopic variceal ligation was performed safely using multiple ligation devices in an awake state following pre-medication with hydroxyzine, without sudden dyspnea. Endoscopists should be cautious of the use of sedatives in patients with diseases associated with muscle twitching or stiffness, as in the current case. In addition, it is necessary to administer endoscopic treatment in an awake state or under conscious sedation in patients with a high risk of dyspnea.

Abstract
Malignant peripheral nerve sheath tumor (MPNST) of the liver is rare. Most cases of MPNST are accompanied by neurofibromatosis 1 (NF-1, von Recklinghausen's disease). We herein report an autopsy case of MPNST without NF-1 and review the pertinent literature. The tumor occupied the entire lobe of the liver, and was 18 cm in maximum diameter. The tumor revealed necrosis and cystic changes with hemorrhage and it had also metastasized to the peritoneum. Microscopically, the tumor was composed of pleomorphic spindle cells with hyperchromatic nuclei and mitogenic figures. The spindle cells stained positive for both S-100 and vimentin antibodies.

Abstract
Objective We retrospectively investigated the relationship between the tumor response and serial changes in α-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP) during hepatic arterial infusion of a cisplatin powder formulation (CDDP powder) in patients with advanced hepatocellular carcinoma (HCC). Methods Seventy-six advanced HCC patients were analyzed. All HCC patients received high-concentration cisplatin (1.43 mg/mL) via the haptic artery at a dose of 65 mg/m(2). AFP and DCP were measured at baseline and four to eight weeks after treatment, and the antitumor responses were evaluated according to the response evaluation criteria in solid tumours (RECIST) criteria after one or two courses of treatment. The patients were classified into two groups, a decreased group and a non-decreased group, according to the change in the serum levels of AFP and DCP at four to eight weeks compared to baseline. Results The response to treatment of the decreased group (n=16) and non-decreased group (n=60) was complete response/partial response/stable disease/progressive disease (CR/PR/SD/PD) in 4/4/5/3 and 1/11/8/40 patients, respectively. The response rate and disease control rate of the decreased group were significantly higher than those of the non-decreased group (p=0.016 and p<0.001, respectively). The median survival time (MST) of the decreased/non-decreased groups were 25.9/10.6 months, respectively. The cumulative survival rates for the decreased group were significantly higher than those of the non-decreased group (p=0.042). In the multivariate analysis, vascular invasion and the decreased group were significant factors that affected the therapeutic efficacy. Conclusion A decrease in the levels of AFP and DCP after the first treatment with CDDP powder is a good predictor for the antitumor effect and the prognosis.

Abstract
A 66-year-old, interferon-ineligible, treatment-naive man who was diagnosed with chronic hepatitis C due to hepatitis C virus genotype 1b began combination therapy with daclatasvir and asunaprevir. On day 14 of treatment, hepatic reserve and renal function deterioration was observed, while his transaminase levels were normal. Both daclatasvir and asunaprevir were discontinued on day 18 of treatment, because the patient complained of dark urine and a rash on his trunk and four limbs. After discontinuing antiviral therapy, the abnormal laboratory finding and clinical manifestations gradually improved, without recurrence. Our case fulfilled the diagnostic criteria of probable drug reaction with eosinophilia and systemic symptom (DRESS) syndrome. Despite the 18-d treatment, sustained virological response 12 was achieved. Based on the clinical course, we concluded that there was a clear cause-and-effect relationship between the treatment and adverse events. To our knowledge, this patient represents the first case of probable DRESS syndrome that includes concomitant deterioration of hepatic reserve and renal function due to combination therapy with daclatasvir and asunaprevir, regardless of normalization of transaminase levels. Our case suggests that we should pay attention not only to the transaminase levels but also to allergic symptoms associated with organ involvement during combination therapy with daclatasvir and asunaprevir.

Abstract
BACKGROUND Patients with proton pump inhibitor (PPI)-resistant nonerosive reflux disease (NERD) include subgroups that have markedly different pathophysiology. This study aimed to clarify the pathophysiology of NERD by esophageal manometry with 24-hour esophageal impedance and pH monitoring. METHODS Eighteen consecutive outpatients referred to our expert center for functional gastrointestinal motility with suspected PPI-resistant NERD were enrolled. Manometry was performed to detect esophageal motility disorders. Subsequently, 24-hour esophageal impedance and pH monitoring was done while patients were on PPI therapy. RESULTS Manometry revealed 1 case of achalasia, 1 case of nutcracker esophagus and 3 cases of diffuse esophageal spasm. Three patients had ineffective esophageal motility, with impedance and pH monitoring being performed in 2 of them. Esophageal acid exposure (%time pH <4) was normal in both, but the symptom index (SI) was positive for nonacidic reflux in 1 patient. One of the 10 patients with normal esophageal motility had abnormal esophageal acid exposure. The SI was positive for weakly acidic and nonacidic reflux in 3 of the remaining 9 patients with normal esophageal acid exposure. Five of the other 6 patients seemed to have functional heartburn. CONCLUSION A substantial percentage (28%) of patients with suspected PPI-resistant NERD had primary esophageal motility disorders. Both nonacidic reflux and weakly acidic reflux are important contributors to the symptoms of patients with PPI-resistant NERD. Esophageal manometry is required to exclude motility disorders, while 24-hour esophageal impedance and pH monitoring is invaluable for assessing symptom-reflux associations and the indications for fundoplication in patients with suspected PPI-resistant NERD.

Abstract
BACKGROUND During maintenance proton pump inhibitor (PPI) therapy, patients with gastroesophageal reflux disease (GERD) sometimes complain of upper gastrointestinal symptoms. AIM To evaluate upper gastrointestinal symptoms in patients on maintenance PPI therapy for erosive GERD or non-erosive reflux disease (NERD) without endoscopic mucosal breaks by using a new questionnaire. METHODS At Gunma University Hospital over a 12-month period during 2011-2012, we enrolled 30 consecutive patients with erosive GERD and 46 patients with NERD. All patients had been on maintenance PPI therapy for more than 1 year. We used the modified frequency scale for the symptoms of GERD (mFSSG) questionnaire to assess upper gastrointestinal symptoms. We also asked patients about their satisfaction with maintenance therapy and whether they wished to change their current PPI. RESULTS The NERD patients had significantly higher symptom scores than the erosive GERD patients. There was no difference in the treatment satisfaction rate between patients with erosive GERD and NERD, but more patients with NERD wanted to change their PPI therapy. There was no difference in the mFSSG score between NERD patients who wished to change their current PPI therapy and those who were satisfied with it. CONCLUSIONS During maintenance PPI therapy, upper gastrointestinal symptoms were more severe in NERD patients than in patients with erosive GERD. NERD patients often wished to change their PPI therapy, but this was not dependent on the severity of their upper GI symptoms.

Abstract
OBJECTIVES The aim of this study was to assess the long-term prognosis, efficacy, and safety of combination therapy using ursodeoxycholic acid (UDCA) and bezafibrate (BF) for primary biliary cirrhosis (PBC) patients exhibiting dyslipidemia. METHODS We performed a prospective, randomized, controlled, multicenter study to compare the long-term clinical results between combination therapy and UDCA monotherapy for patients refractory to UDCA monotherapy. Twenty-seven consecutive PBC patients were enrolled. RESULTS The median treatment period in the UDCA and UDCA+BF groups was 107 and 110 months, respectively. The serum alkaline phosphatase (ALP) levels and the Mayo risk score in the combination therapy group (mean 290 IU/l and 0.91, respectively) were significantly lower than those in the UDCA monotherapy group (mean 461 IU/l and 1.42, respectively) at 8 years after the beginning of the study (P<0.05). The serum creatinine levels in the combination therapy group (mean 0.94 mg/dl) were significantly higher than those in the UDCA monotherapy group (mean 0.56 mg/dl) at 8 years after the beginning of the study (P<0.05). However, the survival rate was not significantly different between the groups. We observed dose reduction or discontinuation of the administration of BF, but not UDCA, due to renal dysfunction or muscle pain. CONCLUSIONS Long-term combination therapy significantly improved the serum ALP levels and the Mayo risk score. However, the survival rate was not significantly different between the groups. In addition, long-term combination therapy significantly increased the serum creatinine levels. We should pay close attention to adverse events during this long-term combination therapy.
