A comprehensive evaluation of an animal model for Helicobacter pylori-associated stomach cancer: Fact and controversy.

Even though Helicobacter pylori infection was the most causative factor of gastric cancer, numerous in vivo studies failed to induce gastric cancer using H. pylori infection only. The utilization of established animal studies in cancer research is crucial as they aim to investigate the coincidental association between suspected oncogenes and pathogenesis as well as generate models for the development and testing of potential treatments. The methods to establish gastric cancer using infected animal models remain limited, diverse in methods, and showed different results. This study investigates the differences in animal models, which highlight different pathological results in gaster by literature research. Electronic databases searched were performed in PubMed, Science Direct, and Cochrane, without a period filter. A total of 135 articles were used in this study after a full-text assessment was conducted. The most frequent animal models used for gastric cancer were Mice, while Mongolian gerbils and Transgenic mice were the most susceptible model for gastric cancer associated with H. pylori infection. Additionally, transgenic mice showed that the susceptibility to gastric cancer progression was due to genetic and epigenetic factors. These studies showed that in Mongolian gerbil models, H. pylori could function as a single agent to trigger stomach cancer. However, most gastric cancer susceptibilities were not solely relying on H. pylori infection, and numerous factors are involved in cancer progression. Further study using Mongolian gerbils and Transgenic mice is crucial to conduct and establish the best models for gastric cancer associated H. pylori.

Depression Symptoms and Inflammation in Chronic Functional Constipation Patients.

BACKGROUND: Inflammation in chronic functional constipation (CFC) occurs systemically and has association with depressive symptoms. Biomarkers of inflammation can be assessed by the neutrophil to lymphocyte ratio and platelet to lymphocyte ratio. These inflammation biomarkers are stable, cheap, and widely available. This study aimed to determine the profile and the correlations between depressive symptoms and inflammation in CFC patients. METHODS: This cross-sectional study involved subjects aged 18-59 years with chronic functional constipation. We use validated Beck Depression Inventory-II (BDI-II) to assess depressive symptoms. We collected the data regarding complete peripheral blood examination, liver function, kidney function, electrolytes, and neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR). Bivariate analysis with Chi-Square test for categorical data and t-test or ANOVA test for numerical data. Multivariate analysis used logistic regression to look at risk factors for depression with p < 0.05 as a statistical significant level. RESULTS: A total of 73 subjects with CFC were recruited with a mean age is 40.2 years, mostly women and working as housewives. Proportion of depressive symptoms in CFC patients was 73.0%, including mild depression 16.4%, moderate depression 17.8%, and severe depression (28.8%). The mean NLR in non-depressive subjects was 1.8 (SD 0.7), while in depressive subjects was 1.94 (SD 0.1) (p>0.05). The mean NLR in mild depression subjects was 2.2 (SD 1.7), in moderate depression was 2.0 (SD 0.7), and in severe depression was 1.9 (SD 0.5) (p>0.05). The mean PLR in non-depressive subjects was 134.3 (SD 0.1), whereas in depressive subjects it was 138.9 (SD 46.0) (p>0.05). The mean PLR in mild depression subjects was 142.9 (SD 60.6), in moderate depression was 135.4 (SD 41.2), and in major depression was 139.0 (SD 37.1) (p>0.05). CONCLUSION: This study found that CFC patients were middle-aged, mostly women and working as a housewife. In general, biomarkers of inflammation were found to be higher in depressive subjects than non-depressive subjects, although not statistically significant.

Current Updates on Diagnosis and Management of Cholangiocarcinoma: from Surgery to Targeted Therapy.

Cholangiocarcinoma is commonly described as any malignancy arising from the lining of the bile duct and is recognized as one of the most common biliary malignancies. We conducted a literature review of current available evidences and guidelines.Based on the anatomical location of the origin of the mass, cholangiocarcinoma can be divided into intrahepatic, perihilar, and distal cholangiocarcinoma. Each of these subtypes has their own risk factors, best treatment options, and prognosis. The most common risk factors for cholangiocarcinoma also differs based on geography and population backgrounds. Histopathological biopsy remained the gold standard for cholangiocarcinoma diagnosis, however various advances has been made in diagnostic procedure, including MRCP, EUS, ERCP, EBUS, and cholangioscopy. Surgical resection is still the best treatment modality for cholangiocarcinoma, but it can only be done in few patients considering most patients were diagnosed in the unresectable state. Other treatment options includes conventional chemotherapy, locoregional therapy, systemic targeted therapy, and palliative best supportive care. Cholangiocarcinoma has an abundance of molecular targets and advances in biomolecular technologies bring further hope for future curative treatment options. Treatment options should be chosen individually based on each patient's condition and setting. Cholangiocarcinoma is still a major health problem in hepatobiliary malignancies. Multiple options are available for cholangiocarcinoma treatments.

Effects of Modified Diaphragmatic Training on Gastroesophageal Reflux Disease Questionnaire Score, Diaphragmatic Excursion, and Maximum Inspiratory Pressure in Adults with Gastroesophageal Reflux Disease After COVID-19: A Single-Blinded Randomized Control.

BACKGROUND: Although diaphragmatic training has been shown to improve gastroesophageal reflux disease (GERD) symptoms, its effectiveness in adults with GERD after COVID-19 has not been evaluated. This study examined the effectiveness of modified diaphragmatic training (MDT) on GERD questionnaire (GERDQ) score, diaphragmatic excursion, and maximum inspiratory pressure (MIP) in adults with GERD after COVID-19. METHODS: This single-blinded randomized control trial was conducted at Persahabatan Hospital from February to April 2023. The medical records of 364 patients with persistent gastrointestinal symptoms were evaluated; among these potential participants, 302 had symptoms before, and 62 after, COVID-19 infection. Fifty of these patients fulfilled the study inclusion and exclusion criteria and were randomly assigned to the intervention (n = 25) or control (n = 25) groups. Four weeks of diaphragmatic training were followed by MDT or standard diaphragmatic training. A follow-up assessment was conducted 30 days after the beginning of the training. RESULTS: The GERDQ score was significantly decreased in the pre-post-intervention group (10.44 ± 2.00 vs 1.84 ± 2.17) and the control group (8.64 ± 0.57 vs 3.32 ± 1.49), with p < 0.001. The intervention group showed significant improvements in the right diaphragmatic excursion (RDE) (44% vs 11.87%), left diaphragmatic excursion (LDE) (46.61% vs 13.62%), and MIP (75.26% vs 23.97%) compared with the control group. CONCLUSION: MDT in adults after COVID-19 with GERD enhanced diaphragmatic excursion and MIP and decreased symptoms of gastroesophageal reflux by 8.60 points of GERDQ. Respiratory symptoms and other side effects were comparable between the groups.

Worldwide Prevalence and Burden of Functional Gastrointestinal Disorders, Results of Rome Foundation Global Study.

BACKGROUND & AIMS: Although functional gastrointestinal disorders (FGIDs), now called disorders of gut-brain interaction, have major economic effects on health care systems and adversely affect quality of life, little is known about their global prevalence and distribution. We investigated the prevalence of and factors associated with 22 FGIDs, in 33 countries on 6 continents. METHODS: Data were collected via the Internet in 24 countries, personal interviews in 7 countries, and both in 2 countries, using the Rome IV diagnostic questionnaire, Rome III irritable bowel syndrome questions, and 80 items to identify variables associated with FGIDs. Data collection methods differed for Internet and household groups, so data analyses were conducted and reported separately. RESULTS: Among the 73,076 adult respondents (49.5% women), diagnostic criteria were met for at least 1 FGID by 40.3% persons who completed the Internet surveys (95% confidence interval [CI], 39.9-40.7) and 20.7% of persons who completed the household surveys (95% CI, 20.2-21.3). FGIDs were more prevalent among women than men, based on responses to the Internet survey (odds ratio, 1.7; 95% CI, 1.6-1.7) and household survey (odds ratio, 1.3; 95% CI, 1.3-1.4). FGIDs were associated with lower quality of life and more frequent doctor visits. Proportions of subjects with irritable bowel syndrome were lower when the Rome IV criteria were used, compared with the Rome III criteria, in the Internet survey (4.1% vs 10.1%) and household survey (1.5% vs 3.5%). CONCLUSIONS: In a large-scale multinational study, we found that more than 40% of persons worldwide have FGIDs, which affect quality of life and health care use. Although the absolute prevalence was higher among Internet respondents, similar trends and relative distributions were found in people who completed Internet vs personal interviews.

Characterization of Helicobacter pylori tlyA and Its Association with Bacterial Density.

BACKGROUND: In the recent studies, a less virulent Helicobacter pylori variant could still colonize the human stomach and induce gastric inflammation, suggesting the involvement of other virulence factors, such as TlyA hemolysin. Nevertheless, the association of TlyA in the pathogenesis of H. pylori infection remains unclear. We investigated the tlyA profile and determined its relationship with gastritis severity. METHODS: An observational study was conducted using DNA stocks and secondary data from previous studies. The tlyA variant was examined by NGS and confirmed with polymerase chain reaction. Gastritis severity was categorized by the Updated Sydney System. The relationship between a variant of tlyA and gastritis severity was determined, in which discrete variables were tested using the χ2 test or Fisher exact test. RESULTS: Two H. pylori tlyA variants were observed and characterized as tlyA1 and tlyA2. We noted a unique variant in the amino acid sequence 32-35 that is exclusively detected among H. pylori isolated from the Papua island. In addition, we observed that the tlyA variant had a significant association with the H. pylori density in the antral (p = 0.002). Histological analyses revealed that TlyA1 was associated with higher H. pylori density than TlyA2. However, we did not observe any significant association of tlyA with the infiltration of inflammation cells. CONCLUSIONS: We observed 2 tlyA variants (tlyA1 and tlyA2). A significant association of tlyA with bacterial density suggested that tlyA plays a more significant role in the colonization process than its influence on the severity of inflammation in gastric mucosa.

A comparison of efficacy and safety of potassium-competitive acid blocker and proton pump inhibitor in gastric acid-related diseases: A systematic review and meta-analysis.

BACKGROUND AND AIM: Potassium-competitive acid blocker (PCAB) is a recent alternative to proton pump inhibitor (PPI) for potent acid suppression. The current systematic review and meta-analysis aimed to compare the efficacy and safety of PCAB versus PPI in treating gastric acid-related diseases. METHODS: We searched up to June 5, 2022, for randomized controlled trials of gastric acid-related diseases that included erosive esophagitis, symptomatic gastroesophageal reflux disease (GERD), peptic ulcers, and Helicobacter pylori infection. The pooled risk ratio (RR) was evaluated for the efficacy outcome and treatment-emergent adverse events (TEAEs) as the safety outcome. Sensitivity analyses were performed to test the robustness of the study findings. RESULTS: Of the 710 screened studies, 19 studies including 7023 participants were analyzed. The RRs for the healing of erosive esophagitis with Vonoprazan versus PPI were 1.09 (95% confidence interval [CI] 1.03-1.14), 1.03 (95% CI 1.00-1.07), and 1.02 (95% CI 1.00-1.05) in Weeks 2, 4, and 8, respectively. There were no differences in the improvement of GERD symptoms and healing of gastric and duodenal ulcers between PCAB and PPI. The pooled eradication rates of H. pylori were significantly higher in Vonoprazan versus PPI first-line treatment (RR 1.13; 95% CI 1.04-1.22). The overall RR of TEAEs with Vonoprazan versus PPI was 1.08 (95% CI 0.89-1.31). Overall, the risk of bias was low to some concerns. Furthermore, sensitivity analyses confirmed the robustness of the study's conclusion. CONCLUSION: Vonoprazan is superior to PPI in first-line H. pylori eradication and erosive esophagitis but non-inferior in other gastric acid-related diseases. Likewise, short-term safety is comparable in both treatment groups.

Urease Levels and Gastritis Stage in Dyspeptic Patients.

BACKGROUND: Dyspepsia is a frequent main symptom of inpatients and outpatients scenario in Indonesia. However, the number of endoscopy facilities are still low, thus the use of non-invasive method to detect gastritis is necessary. We measured the relationship between urease levels and the stage of gastritis in dyspeptic adult patients. METHODS: A cross-sectional study included outpatient dyspepsia patient from November 2018 to February 2019. We examined 14C-Urea Breath Test (UBT) and determined the stage of gastritis based on the Updated Sydney System classification. RESULTS: The urease level of acute and chronic gastritis positive patients were higher than negative patients (p = 0.001, r = 0.353; p <0.0001, r = 0.433, respectively). The AUC value of 14C-UBT to detect acute, chronic, and atrophic gastritis are 0.889, 0.632 and 0.544, respectively. The best cut-off points of 14C-UBT to predict acute gastritis was ≥26.50δ‰ with sensitivity and specificity being 88.89% and 63.95%, respectively. Whereas the best cut-off points for chronic gastritis was ≥34.50δ‰ with 82.89% sensitivity, 63.16% specificity. As for atrophic gastritis, it showed very low AUC value, hence it is not a sufficient test modality to predict atrophic gastritis cases. CONCLUSION: 14C-UBT is sufficient for predicting acute or chronic gastritis but not for atrophic gastritis.

Serum pepsinogen level as a biomarker for atrophy, reflux esophagitis, and gastric cancer screening in Indonesia.

Background: Chronic dyspepsia's symptoms are frequently seen in primary to tertiary healthcare in Indonesia. This study aimed to describe the potential usability of pepsinogen (PG) values in determining gastric mucosal conditions, including superficial gastritis and atrophic gastritis. Materials and Methods: We recruited 646 adult dyspeptic patients and then analyzed PG values (including PGI, PGII, and PGI/II ratio) with endoscopic findings, gastric mucosal damages, and Helicobacter pylori infection. The gastric mucosal damage and H. pylori infection were evaluated using histological examination based on the updated Sydney system. Results: Among 646 enrolled patients, 308 (47.2%), 212 (32.8%), 91 (14.1%), 34 (5.2%), and 1 (0.2%) patient were diagnosed with normal mucosa, gastritis, reflux esophagitis, peptic ulcer disease, and gastric cancer, respectively. Significant differences in PGI, PGII, and PGI/II ratio values were observed among ethnic groups (all P < 0.01). The PGI and PGII levels were significantly higher and PGI/II was significantly lower in H. pylori-infected patients than in uninfected ones (all P < 0.001). The optimal cutoff value for PGII and PGI/II was 12.45 ng/mL with an area under the curve (AUC) value of 0.755 (0.702-0.811), sensitivity 59.3%, and specificity 77.1%; and 4.75 with AUC value of 0.821 (0.763-0.855), sensitivity 81.5%, and specificity 78.7%, respectively, to determine moderate-severe atrophy. Conclusion: Serum PG levels, a useful biomarker, represent the endoscopic findings, especially for reflux esophagitis. In addition, the benefits of PG values detecting atrophic gastritis were limited to moderate-severe atrophic gastritis. This usefulness requires careful attention for several ethnic groups in Indonesia.

Serum Helicobacter pylori antibody reactivity in seven Asian countries using an automated latex aggregation turbidity assay.

BACKGROUND AND AIM: To determine the application range of diagnostic kits utilizing anti-Helicobacter pylori antibody, we tested a newly developed latex aggregation turbidity assay (latex) and a conventional enzyme-linked immunosorbent assay (E-plate), both containing Japanese H. pylori protein lysates as antigens, using sera from seven Asian countries. METHODS: Serum samples (1797) were obtained, and standard H. pylori infection status and atrophy status were determined by culture and histology (immunohistochemistry) using gastric biopsy samples from the same individuals. The two tests (enzyme-linked immunosorbent assay and latex) were applied, and receiver operating characteristics analysis was performed. RESULTS: Area under the curve (AUC) from the receiver operating characteristic of E-plate and latex curves were almost the same and the highest in Vietnam. The latex AUC was slightly lower than the E-plate AUC in other countries, and the difference became statistically significant in Myanmar and then Bangladesh as the lowest. To consider past infection cases, atrophy was additionally evaluated. Most of the AUCs decreased using this atrophy-evaluated status; however, the difference between the two kits was not significant in each country, but the latex AUC was better using all samples. Practical cut-off values were 3.0 U/mL in the E-test and 3.5 U/mL in the latex test, to avoid missing gastric cancer patients to the greatest extent possible. CONCLUSIONS: The kits were applicable in all countries, but new kits using regional H. pylori strains are recommended for Myanmar and Bangladesh. Use of a cut-off value lower than the best cut-off value is essential for screening gastric cancer patients.

Risk factor, diagnosis, and current treatment of H. pylori Infection in Indonesia: A Literature Review.

Helicobacter pylori (H. pylori) infection has become an emerging problem in Indonesia despite its relatively low prevalence as opposed to other Southeast Asian and Asian countries. Strains containing less virulent genotypes predominantly found in Indonesia is suggested to be the rationale for why the disease prevalence, as well as its gastric cancer complication, remain inferior in respect of neighboring counterparts. Although endoscopic evaluation is still necessary to determine the gastric mucosal status of those infected with H. pylori, the infection itself can be easily diagnosed with test-and-treat strategy especially in areas with limited resources. Several findings revealed high rates of antibiotic resistance varying among Indonesian regions and ethnicities, suggesting that triple therapy regimen may not be suitable for all population. Whereas treatment should be based on the pattern of resistance in respected region, novel regimens involving furazolidone, rifabutin, and sitafloxacin are proposed as potential drugs of choice to eradicate H. pylori infection. In order to determine the adequate approach for H. pylori infection in Indonesia, further multicenter studies involving larger sample size should be conducted.

Tocilizumab as a Treatment for 'Cytokine Storm Syndrome' in COVID-19: A Case Report.

Coronavirus disease 19 (COVID-19) which is caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), has been a problem worldwide, particularly due to the high rate of transmission and wide range of clinical manifestations. Acute respiratory distress syndrome (ARDS) and multiorgan failure are the most common events observed in severe cases and can be fatal. Cytokine storm syndrome emerges as one of the possibilities for the development of ARDS and multiorgan failure in severe cases of COVID-19. This case report describes a case of a 53-year-old male patient who has been diagnosed with COVID-19. Further evaluation in this patient showed that there was a marked increase in IL-6 level in blood accompanied with hyperferritinemia, which was in accordance with the characteristic of cytokine storm syndrome. Patient was treated with tocilizumab, a monoclonal antibody and is an antagonist to IL-6 receptor. The binding between tocilizumab and IL-6 receptors effectively inhibit and manage cytokine storm syndrome. Although this case report reported the efficacy of tocilizumab in managing cytokine storm syndrome, tocilizumab has several adverse effects requiring close monitoring. Further clinical randomized control trial is required to evaluate the efficacy and safety of tocilizumab administration in participants with various clinical characteristics and greater number of subjects.

Prognostic Scoring System for Mortality of Hospitalized COVID-19 Patients in Resource-Limited Settings: A Multicenter Study from COVID-19 Referral Hospitals.

BACKGROUND: Many studies identified the risk factors and prognostic factors related to in-hospital COVID-19 mortality using sophisticated laboratory tests. Cost and the availability of supporting blood tests may be problematic in resource-limited settings. This multicenter cohort study was conducted to assess the factors associated with mortality of COVID-19 patients aged 18 years and older, based on history taking, physical examination, and simple blood tests to be used in resource-limited settings. METHODS: The study was conducted between July 2020 and January 2021 in five COVID-19 referral hospitals in Indonesia. Among 1048 confirmed cases of COVID-19, 160 (15%) died during hospitalization. RESULTS: Multivariate analysis showed eight predictors of in-hospital mortality, namely increased age, chronic kidney disease, chronic obstructive pulmonary disease, fatigue, dyspnea, altered mental status, neutrophil-lymphocyte ratio (NLR) ≥ 5.8, and severe-critical condition. This scoring system had an Area-under-the-curve (AUC) of 84.7%. With cut-off score of 6, the sensitivity was 76.3% and the specificity was 78.2%. CONCLUSION: The result of this practical prognostic scoring system may be a guide to decision making of physicians and help in the education of family members related to the possible outcome.

Characterization of a novel Helicobacter pylori East Asian-type CagA ELISA for detecting patients infected with various cagA genotypes.

Currently, Western-type CagA is used in most commercial Helicobacter pylori CagA ELISA kits for CagA detection rather than East Asian-type CagA. We evaluated the ability of the East Asian-type CagA ELISA developed by our group to detect anti-CagA antibody in patients infected with different cagA genotypes of H. pylori from four different countries in South Asia and Southeast Asia. The recombinant CagA protein was expressed and later purified using GST-tag affinity chromatography. The East Asian-type CagA-immobilized ELISA was used to measure the levels of anti-CagA antibody in 750 serum samples from Bhutan, Indonesia, Myanmar, and Bangladesh. The cutoff value of the serum antibody in each country was determined via Receiver-Operating Characteristic (ROC) analysis. The cutoff values were different among the four countries studied (Bhutan, 18.16 U/mL; Indonesia, 6.01 U/mL; Myanmar, 10.57 U/mL; and Bangladesh, 6.19 U/mL). Our ELISA had better sensitivity, specificity, and accuracy of anti-CagA antibody detection in subjects predominantly infected with East Asian-type CagA H. pylori (Bhutan and Indonesia) than in those infected with Western-type CagA H. pylori predominant (Myanmar and Bangladesh). We found positive correlations between the anti-CagA antibody and antral monocyte infiltration in subjects from all four countries. There was no significant association between bacterial density and the anti-CagA antibody in the antrum or the corpus. The East Asian-type CagA ELISA had improved detection of the anti-CagA antibody in subjects infected with East Asian-type CagA H. pylori. The East Asian-type CagA ELISA should, therefore, be used in populations predominantly infected with East Asian-type CagA.

Gastric microbiota and Helicobacter pylori in Indonesian population.

BACKGROUND: The profile of gastric mucosal microbiota has not yet been described in the Indonesian population where the prevalence of Helicobacter pylori is low. METHODS: This is a cross-sectional study analyzing 16S rRNA of 137 gastric biopsy specimens. We analyzed the association between gastric microbiota, H. pylori infection, and gastric mucosal damage. RESULT: Among 137 analyzed samples, 27 were H. pylori-positive and 110 were H. pylori -negative based on culture, histology, and 16S rRNA gene analysis. Significantly lower α-diversity parameters, including Pielou's index, was observed in H. pylori-infected individuals compared with noninfected individuals (all P < .001). Among H. pylori-negative individuals, the permutational analysis of variance of Bray-Curtis dissimilarity distances showed a significant association with different ethnicities, suggesting some ethnic groups had specific microbiota profiles based on the presence of different operational taxonomic units. The linear discriminant analysis effect size (LEfSe) of the H. pylori-negative group showed significant associations between the presence of Micrococcus luteus and Sphingomonas yabuuchiae with Timor and Papuan ethnicities, respectively. The presence of Bulledia sp and Atopobium sp was associated with the Javanese ethnicity. We observed lower α-diversity scores in individuals with gastric mucosal damage and profiles with high abundances of Paludibacter sp and Dialister sp based on LEfSe analysis. CONCLUSION: Our findings suggest the presence of H. pylori is more correlated with a distinct microbiome profile than ethnic precedence.

Six-month Survival of Patients with Malignant Distal Biliary Stricture Following Endoscopic Biliary Stent Procedure and Its Associated Factors.

BACKGROUND: unresectable malignant distal biliary stricture patients require endoscopic biliary stent placement procedure. The survival rate and its associated factors in Indonesia are unknown. OBJECTIVES: To identify 6-month survival of patients with malignant distal biliary stricture following endoscopic biliary stent procedure and its associated factors. METHODS: a retrospective cohort study was conducted using medical records of patients with unresectable malignant distal biliary stricture, which involved caput of pancreas, ampulla of Vater or distal cholangiocarcinoma following endoscopic biliary stent procedure between June 2015 and August 2017 at Cipto Mangunkusumo National Central General Hospital. The cumulative survival was defined by using the Kaplan-Meier curve. Bivariate and multivariate analyses were performed using Cox regression of some factors including failure of biliary stent insertion, bleeding, sepsis, comorbidities, malnutrition, and serum albumin levels. RESULTS: out of total 120 subjects, 85 subjects died within 6 months following the stent procedure with a proportion of 180-day survival of 24% and a median survival of 81 days (CI 95%: 56-106 days). In bivariate analysis, factors of comorbidities, sepsis, malnutrition and albumin levels ≤ 3.0 g/dL had p values of < 0.25; while the subsequent multivariate analysis showed that albumin level of ≤ 3.0 g/dL had HR of 2.73 (CI 95%: 1.48 - 5.05; p = 0.001). CONCLUSION: the 6-month survival following endoscopic biliary stent procedure is 24% with a median survival of 81 days. Albumin level of ≤ 3.0 g/dL has a 2.73 times greater risk for 6-month mortality rate.

A Clinical and Procedural Guideline for Gastrointestinal Endoscopy Units during COVID-19 Pandemic Era.

The World Health Organization (WHO) has declared COVID-19 as global pandemic since there are tremendous growing numbers of confirmed cases for SARS-C0V-2 infection, the number of affected countries and high mortality rate. The global COVID-19 pandemic also will affect various aspects of health care including endoscopic service. The Indonesian Society for Digestive Endoscopy (ISDE), which provides a scope for doctors who perform endoscopic procedures, has developed a clinical and procedural guideline that may serve as a reference for doctors performing gastrointestinal endoscopy in Indonesia.

COVID-19 in Indonesia: Challenges and Multidisciplinary Perspectives for a Safe and Productive New Normal.

The COVID-19 pandemic has caused disruption in all aspects of life, and countries around the world have been combating this pandemic using multiple approaches. Success in one country does not guarantee a transferable approach to other countries with different contexts. This review describes the challenges of COVID-19 management in Indonesia as a populous, socially and culturally diverse, and archipelagic country. It aims to provide multidisciplinary perspectives for a safe, evidence-based, and productive new normal as well as a comprehensive and integrated actionable policy for COVID-19 control.

Detecting the Helicobacter pylori 16S rRNA Gene in Dyspepsia Patients Using Real-Time PCR.

BACKGROUND: early detection of H. pylori is essential to prevent the development of infections into gastric malignancies. The coccoid form of H. pylori is difficult to detect either by culture or histopathology; however, it can be detected using molecular methods, such as real-time PCR. The study was expected to provide new information on the development of H. pylori detection. METHODS: a cross-sectional study was conducted at the Gastrointestinal Endoscopy Center of Cipto Mangunkusumo Hospital between October 2016 and August 2017. The sampling method used was consecutive sampling. Biopsy from gastric antrum and corpus were performed in 64 patients. We collected 2 specimens from each site to be examined using real-time PCR and histopathology. Initially, we conducted real-time PCR optimization followed by application of clinical samples from gastric biopsy. Data analysis using McNemar's χ2 and Kappa tests. RESULTS: the real-time PCR showed 25% positivity, while the positive proportion of histopathological examination was 14%. Real-time PCR has a sensitivity and specificity 88.9% dan 85.5%, respectively. The McNemar's χ2 test showed that there is significantly different (p=0.039) between the two tests; kappa value (p=0.561).  Conclusion: the real-time PCR examination is more sensitive than histopathology. This technique can improve diagnosis by 11% compared to histopathological examination.

Factors associated with health-related quality of life in patients with functional dyspepsia.

BACKGROUND: Health-related quality of life (HRQoL) assessment is important for patients with functional dyspepsia. However, no studies have assessed factors associated with HRQoL reduction in such patients in an Asian population. This study aimed to determine the contribution of clinical, psychosocial, and demographic factors to HRQoL in affected patients in Indonesia. METHODS: In a cross-sectional study, we recruited 124 patients in a tertiary hospital with functional dyspepsia according to Rome III criteria. HRQoL was measured using the Medical Outcomes Study Short-Form 36 (SF-36) physical component summary (PCS) and mental component summary (MCS) and compared with 2009 United States population norms. The factors investigated were age, gender, symptom severity, education level, employment status, anxiety, depression, and ethnicity. Factors associated with reduced HRQoL were identified using linear regression analysis. RESULTS: All domains of HRQoL except vitality were impaired in patients with functional dyspepsia. The mean PCS was 42.3 (SD = 8.4); and the mean MCS was 47.8 (SD = 10). Increasing age (p = 0.002), female gender (p = 0.006), low-to-mid education level (p = 0.015) and greater symptom severity (p < 0.001) were significantly associated with impaired PCS (R2 = 0.36). Female gender (p = 0.047), greater symptom severity (p = 0.002), anxiety (p = 0.001), and depression (p = 0.002 were all significantly associated with an impaired MCS (R2 = 0.41). There were no significant associations between HRQoL and with ethnic group (Javanese/non-Javanese) or employment status. CONCLUSIONS: There was significant HRQoL impairment in these patients with functional dyspepsia in Indonesia. Anxiety, depression, increasing age, female gender, greater symptom severity, and low-to-mid education level were significant factors associated with low HRQoL.  TRIAL REGISTRATION: ClinicalTrials.gov NCT03321383 .
