Abstract
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.

Malaysian joint societies' consensus recommendations on diagnosis and management of disorders of esophagogastric junction outflow. J Gastroenterol Hepatol 2024; 39:431-445. [PMID: 38087846 DOI: 10.1111/jgh.16403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 09/13/2023] [Accepted: 10/18/2023] [Indexed: 03/05/2024]
Abstract
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.

Frequency of significant steatosis and compensated advanced chronic liver disease among adults with chronic liver disease. J Gastroenterol Hepatol 2023; 38:1818-1822. [PMID: 37587719 DOI: 10.1111/jgh.16313] [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: 03/18/2023] [Revised: 05/31/2023] [Accepted: 07/19/2023] [Indexed: 08/18/2023]
Abstract
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.

Abstract
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.

Abstract
OBJECTIVE Small intestinal bacterial overgrowth (SIBO) is recognised to have an association with irritable bowel syndrome (IBS), but the impact of SIBO on symptoms and health-related quality of life (HRQOL) in IBS patients is still unknown. METHODS A cross-sectional study of consecutive adult patients who underwent glucose hydrogen breath test was conducted. Factors associated with SIBO were evaluated. Symptom and HRQOL of IBS patients with and without SIBO were compared. The independent factors associated with severe IBS (i.e. IBS symptom severity score: IBS-SSS > 300) 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 SIBO (SIBO: 50.0% vs non-SIBO: 29.0%, p = 0.019). Amongst IBS patients, severe IBS was associated with SIBO (36.4% vs 15.6%, p = 0.043). The presence of SIBO was associated with poorer HRQOL (EQ-5D utility score: 0.73 (0.69-0.78) vs 0.80 (0.73-1.00), p = 0.024]. The presence of 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 at univariate analysis. However, SIBO was the only independent factor associated with severe IBS at multivariate analysis [OR: 3.83 (95% CI: 1.02-14.34), p = 0.046]. CONCLUSIONS There was a significant association between IBS-D and SIBO. The co-existence of SIBO had a significant negative impact on IBS patients. This article is protected by copyright.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVE Functional gastrointestinal disorders (FGIDs) are known to have a significant impact on patients' quality of life and lead to a greater healthcare burden. In this study we aimed to investigate whether this healthcare burden differs among various types of FGIDs in secondary care. METHODS A retrospective study of consecutive adults with luminal gastrointestinal (GI) diseases in a secondary healthcare gastroenterology clinic was conducted. The frequency of FGIDs and differences in healthcare utilization among different types of FGIDs were explored. RESULTS Among 1206 patients with luminal GI disease, 442 (36.7%) had FGIDs. FGIDs patients were older (67 y vs 62 y, P < 0.001) with a higher proportion of women (61.8% vs 50.4%, P < 0.001) than those without FGIDs. Functional dyspepsia (FD) was the most common FGIDs (36.9%), followed by irritable bowel syndrome (IBS) (30.3%). A high healthcare burden (defined as over one GI endoscopy or imaging examination over 5 years, or one or more unscheduled visit to general practitioner or emergency department or hospitalization annually) was observed among 53.8% of the FGIDs patients. FD was associated with a high healthcare burden (high vs low burden: 43.7% vs 28.9%, P = 0.001) while IBS was associated with lower healthcare burden (high vs low burden: 25.2% vs 36.3%, P = 0.012). On multivariate analysis, only FD was significantly associated with high healthcare burden (adjusted odds ratio 1.996, 95% confidence interval 1.117-3.567, P = 0.020). CONCLUSION Compared with other FGIDs, FD was the most common condition in secondary care, and it was associated with the greatest healthcare burden.

Abstract
BACKGROUND AND AIM The association between body mass index (BMI) and functional gastrointestinal disorders (FGIDs) has been inconsistent. We aimed to explore the association of BMI with FGIDs in a primary care setting to provide more data in this area. METHODS A cross-sectional study of consecutive Asian adults attending a primary healthcare setting was conducted. This study was conducted in 2 phases: The association between BMI and common FGIDs (functional diarrhea/FD, irritable bowel syndrome/IBS, functional diarrhea and functional constipation/FC) was studied initially. The influence of anxiety and depression on BMI and FGIDs was additionally explored in phase 2. RESULTS A total of 1002 subjects (median age 32 years, 65.4% females, 90.7% Malay ethnicity, 73.2% higher than secondary level education) were recruited between August 2019 to January 2020. The majority of subjects were obese (39.2%), and had central obesity (51.7%), while 6.1% had metabolic syndrome. The prevalence of FD, IBS, functional diarrhea and FC were 7.5% (n = 75), 4.0% (n = 40), 1.2% (n = 12) and 10.5% (n = 105) respectively, based on the Rome III criteria. Among individual FGIDs, FD subjects had more underweight adults (BMI<18.5kg/m2) compared to controls (13.3% vs 3.5%, P = 0.002) and being underweight remained as an independent association with FD [OR = 3.648 (95%CI 1.494-8.905), P = 0.004] at multi-variate analysis. There were no independent associations between BMI and other FGIDs. When psychological morbidity was additionally explored, anxiety (OR 2.032; 95%CI = 1.034-3.991, p = 0.040), but not depression, and a BMI<18.5kg/m2 (OR 3.231; 95%CI = 1.066-9.796, p = 0.038) were found to be independently associated with FD. CONCLUSIONS FD, but not other FGIDs, is associated with being underweight. This association is independent of the presence of anxiety.

Abstract
BACKGROUND Alteration in the natural history of Crohn's disease (CD) since the advent of biologic therapy remains to be proven. Our aim was to look at the intestinal surgical rates and the association with biologic therapy over the last two decades. METHODS This was a retrospective study in which all CD patients seen in two tertiary referral hospitals in Malaysia were recruited. Patients were stratified into two cohorts; cohort 1 was patients diagnosed from year 1991 to 2000 and cohort 2 was patients diagnosed from year 2001 to 2010. These time cohorts were selected based on initial availability of biologic agents in Malaysia in year 2000. Details of demography, disease location, medications and cumulative surgical rates over 7 years were recorded. RESULTS A total of 207 patients were recruited: 70 from cohort 1 and 137 from cohort 2. Differences seen in terms of disease location, phenotype, and use of immunomodulatory therapy between the two cohorts were not significant. Patients who were ever exposed to biologics were significantly different between the two cohorts, approximately two times higher at 35.8% (n = 49) in cohort 2, and 18.6% (n = 13) in cohort 1, p = 0.011. There was a significant reduction in the 7-year cumulative intestinal surgical rates between cohort 1 and cohort 2, from 21.4% (n = 15) to 10.2% (n = 14), p = 0.028. However, there was no statistically significant difference in biologic exposure between those who underwent surgery and those who did not. CONCLUSIONS There has been a significant reduction in intestinal surgical rates for Crohn's disease over the last two decades but does not appear to be associated with the increased use of biologics.

Abstract
Dengue infection is epidemic but ocular complications of dengue are less reported. We report a case of dengueinfected patient with disturbing ocular symptoms. He was admitted for severe dengue. Subsequently, he presented with symptoms of bilateral central scotoma with metamorphosia. Fundus examination revealed cotton wool spots and flame-shaped haemorrhages at the macula, with dull foveal light reflex. He was diagnosed with bilateral dengue maculopathy. The patient was managed conservatively with surveillance. One week later, his eye symptoms improved and were resolved six months later. Early recognition and close monitoring remains the key to successful management and interventions are rarely needed.

Abstract
Patients with poorly controlled diabetes mellitus have an increased risk of lower limb infection and gangrene. In Malaysia, they frequently present late and are often in septic shock with multi-organ dysfunction. We report on two patients who presented for lower limb amputation in a desperate attempt to control sepsis and save their lives. Both patients were classified as ASA 5. Both patients had successfully undergone surgery under low dose unilateral spinal anaesthesia. The anaesthetic management of these critically ill patients in view of limited resources is discussed.

Pulmonary hypertension in pregnancy is a rare condition but is associated with a high mortality. We report the case of a 29 year old female in early pregnancy with Protein C and S deficiency with recurrent deep venous thrombosis and pulmonary embolism and subsequent secondary pulmonary hypertension. The patient was counselled and consented for termination of pregnancy with tubal sterilization. She was administered continuous spinal anaesthesia with invasive monitoring. The successful anaesthetic management of this condition is described.
