RESUMO
Disorders of esophagogastric junction (EGJ) outflow, including achalasia and EGJ outflow obstruction, are motility disorders characterized by inadequate relaxation of lower esophageal sphincter with or without impaired esophageal peristalsis. Current guidelines are technical and less practical in the Asia-Pacific region, and there are still massive challenges in timely diagnosis and managing these disorders effectively. Therefore, a Malaysian joint societies' task force has developed a consensus on disorders of EGJ outflow based on the latest evidence, while taking into consideration the practical relevance of local and regional context and resources. Twenty-one statements were established after a series of meetings and extensive review of literatures. The Delphi method was used in the consensus voting process. This consensus focuses on the definition, diagnostic investigations, the aims of treatment outcome, non-surgical or surgical treatment options, management of treatment failure or relapse, and the management of complications. This consensus advocates the use of high-resolution esophageal manometry for diagnosis of disorders of EGJ outflow. Myotomy, via either endoscopy or laparoscopy, is the preferred treatment option, while pneumatic dilatation can serve as a secondary option. Evaluation and management of complications including post-procedural reflux and cancer surveillance are recommended.

BACKGROUND & AIMS: Drug development in nonalcoholic steatohepatitis (NASH) is hampered by a high screening failure rate that reaches 60% to 80% in therapeutic trials, mainly because of the absence of fibrotic NASH on baseline liver histology. MACK-3, a blood test including 3 biomarkers (aspartate aminotransferase, homeostasis model assessment, and cytokeratin 18), recently was developed for the noninvasive diagnosis of fibrotic NASH. We aimed to validate the diagnostic accuracy of this noninvasive test in an international multicenter study. METHODS: A total of 1924 patients with biopsy-proven nonalcoholic fatty liver disease from 10 centers in Asia, Australia, and Europe were included. The blood test MACK-3 was calculated for all patients. FibroScan-aspartate aminotransferase score (FAST), an elastography-based test for fibrotic NASH, also was available in a subset of 655 patients. Fibrotic NASH was defined as the presence of NASH on liver biopsy with a Nonalcoholic Fatty Liver Disease Activity Score of 4 or higher and fibrosis stage of F2 or higher according to the NASH Clinical Research Network scoring system. RESULTS: The area under the receiver operating characteristic of MACK-3 for fibrotic NASH was 0.791 (95% CI 0.768-0.814). Sensitivity at the previously published MACK-3 threshold of less than 0.135 was 91% and specificity at a greater than 0.549 threshold was 85%. The MACK-3 area under the receiver operating characteristic was not affected by age, sex, diabetes, or body mass index. MACK-3 and FAST results were well correlated (Spearman correlation coefficient, 0.781; P < .001). Except for an 8% higher rate of patients included in the grey zone, MACK-3 provided similar accuracy to that of FAST. Both tests included 27% of patients in their rule-in zone, with 85% specificity and 35% false positives (screen failure rate). CONCLUSIONS: The blood test MACK-3 is an accurate tool to improve patient selection in NASH therapeutic trials.

BACKGROUND: With changes in the epidemiology and treatment of chronic liver disease (CLD), the impact of various etiologies of liver disease on steatosis and advanced fibrosis are uncertain. METHODS: A retrospective study was conducted among liver disease patients of various etiologies undergoing transient elastography (TE) over a 9-year duration. RESULTS: Data for 2886 patients were analyzed and had the following demographics: The median age was 60 (IQR: 45-69) years, 51% were males, and ethnicity was predominantly Chinese (52.5%), followed by Malays (34%) and Indians (12.3%). The median CAP score was 272 (IQR: 219-319) dB/m and the median liver stiffness measurement (LSM) score was 6.5 (IQR: 4.9-9.7) kPa. Hepatic steatosis occurred across the spectrum of etiologies of CLD. Among patients with steatosis, the most common etiologies were nonalcoholic fatty liver disease (NAFLD) at 62% and chronic hepatitis B (CHB) at 26.3%. TE findings suggestive of cACLD (10.1-15 kPa) and highly suggestive of cACLD (>15 kPa) were observed in 11.3% and 12.4% of patients, respectively. NAFLD was found to be the most common etiology for cases with suggestive of cACLD (47.2%) and highly suggestive of cACLD (41.5%). CONCLUSION: Hepatic steatosis is common in CLD, regardless of etiology. Compared with other etiologies, NAFLD is now the leading cause of cACLD.

INTRODUCTION AND OBJECTIVES: The Hepamet fibrosis score was introduced for the diagnosis of advanced liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD). To date, external validation is limited, and its utility in combination with liver stiffness measurement (LSM) has not been explored. MATERIAL AND METHODS: This is a cross-sectional study on NAFLD patients who had a liver biopsy and LSM on the same day. The diagnostic performance of the Hepamet fibrosis score was evaluated using the area under the receiver operating characteristic curve (AUROC). RESULTS: The data for 196 patients were analyzed (mean age 50 ± 11 years old, 50% men, 56.6% Malay, 27.6% Chinese, 15.8% Indian, 67.9% NASH, 15.8% advanced liver fibrosis). The AUROC of Hepamet fibrosis score for the diagnosis of advanced liver fibrosis was 0.85 (95% CI, 0.80 - 0.91). Using the <0.12 and ≥0.47 cut-offs from the original study, the sensitivity, specificity, positive predictive value, negative predictive value, the proportion of indeterminate results and misclassification rate were 81.8%, 91.8%, 47.4%, 98.2%, 32.1% and 6.1%, respectively. Using LSM <10 kPa and ≥15 kPa for the diagnosis of absence and presence of advanced liver fibrosis, respectively, in patients with Hepamet fibrosis score ≥0.47 (i.e., the two-step approach) reduced indeterminate results and misclassification to 16.1% and 3.6%, respectively. CONCLUSIONS: We found the Hepamet fibrosis score to have good diagnostic accuracy in a population that was largely unrepresented in earlier work and demonstrated its utility in a two-step approach with LSM for the diagnosis of advanced liver fibrosis.

BACKGROUND AND AIM: Percutaneous endoscopic gastrostomy (PEG) placement is recommended in patients with amyotrophic lateral sclerosis (ALS), but the procedure is considered high risk. In this study, we aimed to compare the outcome of ALS patients with and without PEG. The success of the procedure and complications of PEG insertion were also explored. METHODS: Patients with ALS who met the criteria for enteral feeding support were consecutively recruited. Patients who consented had PEG insertion using the modified technique of introducer method with transoral ultra-slim endoscopy. RESULTS: A total of 64 patients were recruited, of which 36 (56%) patients consented to PEG. The median age of all patients was 65 years and 59% were male. There was no difference in demographic and clinical characteristics between patients who agreed to a PEG and those who did not. The mortality rate at 6 and 12 months was lower in the PEG cohort compared with non-PEG, but this was not statistically significant (6 months: 28.6% vs 32.2%, P = 0.561; 12 months: 38.9% vs 50.0%, P = 0.374). Amongst the PEG cohort, 61% were stratified high risk and 31% moderate risk. Thirty-one percent of them required long-term home noninvasive ventilation. All patients (100%) underwent successful PEG insertion at single attempt using the modified approach. The complications reported over a period of 6 months were infected PEG site (17%), dislodged gastrostomy tube (14%), and minor bleeding (8%). CONCLUSION: In ALS patients with moderate to high risk of PEG insertion, the introducer technique utilizing ultra-slim endoscopy guidance was well tolerated and safe.

BACKGROUND AND AIM: The spectrum of gastrointestinal (GI) and liver diseases is recognized to have a geographical variation, which may be due to environmental or genetic differences. We aimed to explore this further in a specialist clinic serving a multi-ethnic Asian urban population. METHODS: A retrospective analysis of outpatient data from this institution's electronic medical records was conducted between January and June 2019. Clinical diagnoses of GI and liver diseases and associated demographic information were collected. RESULTS: Data from 3676 adult patients (median age 62 years, female 51.1%) were available for analysis. The frequency of luminal GI, liver and pancreato-biliary diseases were 34.2%, 63.2%, and 2.6%, respectively. Among luminal GI diseases, 38.6% were functional gastrointestinal disorders and 61.4% had an organic cause. A higher proportion of patients of Indian ethnicity were diagnosed with IBD compared with other ethnic groups (India 21.9%, Malay 16.5%, Chinese 12.2%, P = 0.001). Among liver diseases, the most common etiologies were HBV (44.4%) and NAFLD (39.3%). Cirrhosis and/or hepatocellular carcinoma were present in 18% of liver diseases, with NAFLD as the most frequent etiology. Among patients with NAFLD, a higher proportion of ethnic Malays and Indians were evident (Malay 53.8% vs Chinese 28.7% vs Indian 61.1%, P < 0.001). In contrast, a greater proportion of ethnic Chinese were diagnosed with HBV compared with other ethnic groups (Malay 30.9% vs Chinese 57.5% vs Indian 8.4%, P < 0.001). CONCLUSION: The spectrum of GI and liver diseases has a peculiar epidemiology, particularly with reference to the ethnic predilection of certain diseases.

INTRODUCTION: Small intestinal bacterial overgrowth (SIBO) is prevalent in irritable bowel syndrome (IBS), but its' association with other functional gastrointestinal disorders (FGIDs) is less certain. This study aimed to explore SIBO in a multi-racial Asian population with various FGIDs compared to non-FGID controls. METHODOLOGY: Consecutive Asian adults with Rome III diagnosed common FGIDs (functional dyspepsia/FD, IBS and functional constipation/FC) and non-FGID controls were subjected to glucose breath testing, with hydrogen (H2) and methane (CH4) levels determined. RESULTS: A total of 244 participants (FGIDs n = 186, controls n = 58, median age 45 years, males 36%, Malay ethnicity 76%) were recruited. FGIDs had a higher prevalence trend of SIBO compared to controls (16% FGIDs vs. 10% controls, p = 0.278) with 14% in FD, 18% in IBS and 17% in FC. Compared to controls, SIBO was associated with diarrhoea-predominant IBS (IBS-D) (24% vs. 10%, P = 0.050) but not with other types of FGIDs. IBS-D remained an independent predictor of SIBO (OR = 2.864, 95% CI 1.160-7.071, p = 0.023) but not PPI usage nor history of diabetes (both p > 0.050) at multivariate analysis. Compared to controls, SIBO in IBS-D was associated with an elevated H2 level (≥ 20 ppm from baseline) (18% vs. 3%, p = 0.017), but not CH4 levels (≥ 10 ppm) (9% vs. 7%, p = 0.493). In addition, no difference was found in the prevalence of methane-positive SIBO between chronic constipation (constipation-predominant IBS and FC) compared to controls (9% vs. 7%, P = 0.466). CONCLUSION: SIBO is prevalent amongst multi-ethnic Asian adults with and without FGIDs. Amongst various FGIDs, only IBS-D is significantly associated with SIBO.

BACKGROUND AND AIM: Repeating liver stiffness measurement (LSM) was recently reported to improve accuracy to diagnose fibrosis stage in patients with non-alcoholic fatty liver disease (NAFLD). There are to date no other studies confirming this finding. This aims to evaluate the accuracy of repeating LSM for the diagnosis of fibrosis stage in NAFLD patients. METHODS: Retrospective analysis of prospectively collected data on adult NAFLD patients who had two FibroScan examination within 6 months prior to liver biopsy. F3-F4 fibrosis was excluded using LSM cut-off of 7.9 kPa. RESULTS: A total of 136 patients were recruited. Eighty-five percent (115/136) of patients had high baseline LSM (≥ 7.9 kPa). Among them, 25% (29/115) had low repeat LSM (< 7.9 kPa), with only two patients having F3 fibrosis. Forty-eight percent (41/86) of patients with high baseline and repeat LSMs had greater than or equal to F3-F4 fibrosis. All 21 patients with low baseline LSM had F0-F2 fibrosis, except one patient with high repeat LSM who had F3 fibrosis. A strategy of repeating LSM, where only patients with high LSM on both baseline and repeat scans are considered for liver biopsy, will be able to reduce the number of patients being considered for liver biopsy from 85% to 63%. The sensitivity, specificity, positive predictive value, and negative predictive value based on only the baseline scan was 98%, 22%, 37%, and 95%, respectively, while based on the strategy of repeating LSM was 93%, 51%, 48%, and 94%, respectively. CONCLUSION: False positive diagnosis of advanced fibrosis in NAFLD patients can be reduced, and unnecessary liver biopsy can be avoided by repeating LSM.

INTRODUCTION: MACK-3 (combination of hoMa, Ast and CK18) was reported to be a good biomarker for the diagnosis of fibrotic non-alcoholic steatohepatitis (NASH). However, there is no external validation to date. AIM: To evaluate the accuracy of MACK-3 for the diagnosis of fibrotic NASH. METHODOLOGY: Consecutive adult non-alcoholic fatty liver disease (NAFLD) patients who had liver biopsy in a university hospital were included. MACK-3 was calculated using the online calculator using the following variables: fasting glucose, fasting insulin, aspartate aminotransferase (AST) and cytokeratin 18 (CK18). MACK-3 cut-offs ≤0.134 and ≥0.550 were used to predict absence and presence of fibrotic NASH, respectively. Histopathological examination of liver biopsy specimen was reported according to the NASH Clinical Research Network Scoring System. RESULTS: Data for 196 subjects were analysed. MACK-3 was good for diagnosis of fibrotic NASH (area under receiver-operating characteristics curve [AUROC] 0.80), comparable to the Fibrosis-4 index (FIB4) and the NAFLD fibrosis score (NFS) and superior to the BARD score and CK18. MACK-3 was good for diagnosis of active NASH (AUROC 0.81) and was superior to other blood fibrosis tests. The overall accuracy, percentage of subjects in grey zone, sensitivity, specificity, positive predictive value and negative predictive value of MACK-3 for diagnosis of fibrotic NASH was 79.1%, 46.9%, 100%, 43.8%, 43.1% and 100%, respectively, while for diagnosis of active NASH was 90.0%, 39.3%, 84.2%, 81.4%, 88.9% and 74.5%, respectively. CONCLUSION: MACK-3 is promising as a non-invasive test for active NASH and fibrotic NASH and may be useful to identify patients who need more aggressive intervention.

Introduction. Resistance towards amoxicillin in Helicobacter pylori causes significant therapeutic impasse in healthcare settings worldwide. In Malaysia, the standard H. pylori treatment regimen includes a 14-day course of high-dose proton-pump inhibitor (rabeprazole, 20 mg) with amoxicillin (1000 mg) dual therapy.Hypothesis/Gap Statement. The high eradication rate with amoxicillin-based treatment could be attributed to the primary resistance rates of amoxicillin being relatively low at 0%, however, a low rate of secondary resistance has been documented in Malaysia recently.Aim. This study aims to investigate the amino acid mutations and related genetic variants in PBP1A of H. pylori, correlating with amoxicillin resistance in the Malaysian population.Methodology. The full-length pbp1A gene was amplified via PCR from 50 genomic DNA extracted from gastric biopsy samples of H. pylori-positive treatment-naïve Malaysian patients. The sequences were then compared with reference H. pylori strain ATCC 26695 for mutation and variant detection. A phylogenetic analysis of 50 sequences along with 43 additional sequences from the NCBI database was performed. These additional sequences included both amoxicillin-resistant strains (n=20) and amoxicillin-sensitive strains (n=23).Results. There was a total of 21 variants of amino acids, with three of them located in or near the PBP-motif (SKN402-404). The percentages of these three variants are as follows: K403X, 2%; S405I, 2% and E406K, 16%. Based on the genetic markers identified, the resistance rate for amoxicillin in our sample remained at 0%. The phylogenetic examination suggested that H. pylori might exhibit unique conserved pbp1A sequences within the Malaysian context.Conclusions. Overall, the molecular analysis of PBP1A supported the therapeutic superiority of amoxicillin-based regimens. Therefore, it is crucial to continue monitoring the amoxicillin resistance background of H. pylori with a larger sample size to ensure the sustained effectiveness of amoxicillin-based treatments in Malaysia.

BACKGROUND: Real-world data on the outcome of routine treatment for disorders of gut-brain interaction (DGBI) in secondary care are lacking. METHOD: A longitudinal study of consecutive adult patients with various DGBI attending this institution's gastroenterology clinic was conducted. Following 2 years of treatment, the proportion of patients with symptom improvement, details of clinical therapy, factors associated with and the impact of 'no symptom improvement' were determined. RESULTS: A total of 289 patients (median age 68 years; 64.7% females; 28.4% irritable bowel syndrome (IBS), 20.1% functional dyspepsia (FD), 8.7% functional constipation (FC), 42.9% overlap syndrome) were recruited. After 2 years, 66.1% patients reported symptom improvement. Patients with overlap syndrome were less likely to have symptomatic improvement compared to those with a single DGBI (Overlap 55.6% vs IBS 74.4% vs FD 72.4% vs FC 76.0%, p = 0.014). Reassurance was associated with symptom improvement (p < 0.001). On multivariate analysis, overlap syndrome remained significantly associated with a poorer outcome (OR 2.27, 95% CI 1.22-4.25, p = 0.010), while providing reassurance was associated with a positive outcome (OR 0.30, 95% CI 0.16-0.56, p < 0.001). Only 25.6% and 14.9% of patients were referred for a low FODMAP diet and psychiatric intervention respectively. DGBI patients who had 'no improvement' were more likely to seek further GI consultations and had more work absenteeism. CONCLUSION: Two-thirds of DGBI patients in secondary care showed symptom improvement. Patients who were reassured had better symptom improvement, while those with an overlap syndrome were associated with a poorer outcome, resulting in greater healthcare consultation and work absenteeism.

OBJECTIVE: To explore the factors associated with small intestinal bacterial overgrowth (SIBO), and to further evaluate the impact of SIBO on irritable bowel syndrome (IBS) in terms of symptom severity and health-related quality of life (HRQoL). METHODS: A cross-sectional study of consecutive adult patients who underwent glucose hydrogen breath test was conducted. Factors associated with SIBO were evaluated. Symptom severity and HRQoL of IBS patients with and without SIBO were compared. The independent factors associated with severe IBS were explored. RESULTS: A total of 160 patients were included (median age 40 years, males 31.3%). IBS was present among 53.8% of subjects, with 33.8% having diarrhea-predominant IBS (IBS-D). SIBO was diagnosed in 22.5% of the study population. Patients with SIBO were more commonly diagnosed with IBS-D than those without (50.0% vs 29.0%, P = 0.019). Severe IBS was associated with SIBO (36.4% vs 15.6%, P = 0.043). SIBO was associated with poorer HRQoL (Euroqol five-dimensional utility score: 0.73 vs 0.80, P = 0.024). SIBO (44.4% vs 20.6%, P = 0.043), anxiety (77.8% vs. 39.7%, P = 0.004), and depression (50.0% vs 19.1%, P = 0.011) were associated with severe IBS in the univariate analysis. However, SIBO was the only independent factor associated with severe IBS in the multivariate analysis (adjusted odds ratio 3.83, 95% confidence interval CI 1.02-14.34, P = 0.046). CONCLUSIONS: There was a significant association between IBS-D and SIBO. The coexistence of SIBO had a significant negative impact on IBS patients.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the latest term for steatotic liver disease associated with metabolic syndrome. MASLD is the most common cause of chronic liver disease and is the leading cause of liver-related morbidity and mortality. It is important that all stakeholders be involved in tackling the public health threat of obesity and obesity-related diseases, including MASLD. A simple and clear assessment and referral pathway using non-invasive tests is essential to ensure that patients with severe MASLD are identified and referred to specialist care, while patients with less severe disease remain in primary care, where they are best managed. While lifestyle intervention is the cornerstone of the management of patients with MASLD, cardiovascular disease risk must be properly assessed and managed because cardiovascular disease is the leading cause of mortality. No pharmacological agent has been approved for the treatment of MASLD, but novel anti-hyperglycemic drugs appear to have benefit. Medications used for the treatment of diabetes and other metabolic conditions may need to be adjusted as liver disease progresses to cirrhosis, especially decompensated cirrhosis. Based on non-invasive tests, the concepts of compensated advanced chronic liver disease and clinically significant portal hypertension provide a practical approach to stratifying patients according to the risk of liver-related complications and can help manage such patients. Finally, prevention and management of sarcopenia should be considered in the management of patients with MASLD.
RESUMO
BACKGROUND: There are limited data on the long-term adverse clinical outcomes of adults with metabolic dysfunction-associated fatty liver disease (MAFLD). METHODS: This is a single-centre prospective study of a well-characterized cohort of MAFLD patients who underwent liver biopsy and followed every 6-12 months for adverse clinical outcomes. RESULTS: The data for 202 patients were analyzed [median age 55.0 (48.0-61.3) years old; male, 47.5%; obese, 88.6%; diabetes mellitus, 71.3%; steatohepatitis, 76.7%; advanced fibrosis, 27.2%]. The median follow-up interval was 7 (4-8) years. The cumulative incidence of liver-related events, cardiovascular events, malignancy and mortality was 0.43, 2.03, 0.60 and 0.60 per 100 person-years of follow-up, respectively. Liver-related events were only seen in patient with advanced fibrosis at 9.1% vs 0% in patient without advanced liver fibrosis (p < 0.001). The cumulative incidence of liver-related events among patients with advanced fibrosis was 1.67 per 100 person-years of follow-up. When further stratified to bridging fibrosis and cirrhosis, the cumulative incidence of liver-related events was 1.47 and 3.85 per 100 person-years of follow-up, respectively. Advanced fibrosis was not significantly associated with cardiovascular events, malignancy or mortality. The cumulative incidence of liver-related events, cardiovascular events, malignancy and mortality were not significantly different between patients with and without steatohepatitis and between obese and non-obese patients. However, liver-related events were only seen among obese patients. CONCLUSION: Overall, the cumulative incidence of liver-related event is low in patients with MAFLD, but it is much higher among those with advanced fibrosis. However, there is a relatively high cumulative incidence of cardiovascular event among patients with MAFLD.

Patients with Parkinson's disease (PD) face a multitude of gastrointestinal (GI) symptoms, including nausea, bloating, reduced bowel movements, and difficulties with defecation. These symptoms are common and may accumulate during the course of PD but are often under-recognized and challenging to manage. Objective testing can be burdensome to patients and does not correlate well with symptoms. Effective treatment options are limited. Evidence is often based on studies in the general population, and specific evidence in PD is scarce. Upper GI dysfunction may also interfere with the pharmacological treatment of PD motor symptoms, which poses significant management challenges. Several new less invasive assessment tools and novel treatment options have emerged in recent years. The current review provides an overview and a practical approach to recognizing and diagnosing common upper and lower GI problems in PD, e.g., dyspepsia, gastroparesis, small bowel dysfunction, chronic constipation, and defecatory dysfunction. Management aspects are discussed based on the latest evidence from the PD and general populations, with insights for future research pertaining to GI dysfunction in PD.
RESUMO
BACKGROUND: The prevalence of irritable bowel syndrome (IBS) is now known to be similar in various geographical regions, but there has been no study directly comparing characteristics of patients with IBS between populations. AIMS: To evaluate clinical and psychological differences between adults with IBS seen in secondary care in the United Kingdom (UK) and Malaysia. METHODS: Age- and sex-matched patients with IBS from a single centre in the UK (Leeds) and two centres in Malaysia (Kuala Lumpur and Kota Bharu), who fulfilled Rome III criteria, were recruited prospectively. Demographic characteristics and gastrointestinal and psychological symptoms were compared between both groups. RESULTS: A total of 266 (133 UK and 133 Malaysian) age- and sex-matched patients with Rome III IBS were recruited (mean age: 45.1 years Malaysia, vs. 46.5 years UK; 57.9% female). UK patients were more likely to consume alcohol than Malaysian patients (54.1% vs. 10.5%, p < 0.001). Compared with Malaysian patients, UK patients had more frequent abdominal pain, abdominal bloating, meal-related symptoms (p < 0.001 for all), higher symptom scores (mean 268.0 vs 166.0; p < 0.001), greater limitation of activities due to IBS (p = 0.007) and were more likely to report abnormal anxiety scores (p < 0.001). Higher perceived stress (mean 21.3 vs. 19.1, p = 0.014) and gastrointestinal symptom-specific anxiety scores (mean 50.8 vs. 43.0, p < 0.001) were also observed in UK patients. Finally, UK patients had higher somatoform symptom-reporting scores (mean 8.9 vs. 6.9, p < 0.001). CONCLUSIONS: IBS is more severe and is associated with a higher level of psychological symptoms in the UK compared with Malaysian patients in secondary care.
