Helicobacter pylori management in ASEAN: The Bangkok consensus report.

Helicobacter pylori (H. pylori) infection remains to be the major cause of important upper gastrointestinal diseases such as chronic gastritis, peptic ulcer, gastric adenocarcinoma, and mucosa-associated lymphoid tissue lymphoma. H. pylori management in ASEAN: the Bangkok consensus report gathered key opinion leaders for the region to review and evaluate clinical aspects of H. pylori infection and to develop consensus statements, rationales, and grades of recommendation for the management of H. pylori infection in clinical practice in ASEAN countries. This ASEAN Consensus consisted of 34 international experts from 10 ASEAN countries, Japan, Taiwan, and the United States. The meeting mainly focused on four issues: (i) epidemiology and disease association; (ii) diagnostic tests; (iii) management; and (iv) follow-up after eradication. The final results of each workshop were presented for consensus voting by all participants. Statements, rationale, and recommendations were developed from the available current evidence to help clinicians in the diagnosis and treatment of H. pylori and its clinical diseases.

Effectiveness of add-on therapy with domperidone vs alginic acid in proton pump inhibitor partial response gastro-oesophageal reflux disease in systemic sclerosis: randomized placebo-controlled trial.

OBJECTIVES: Twice-daily dosing of proton pump inhibitor (PPI), the standard therapy for gastro-oesophageal reflux disease (GERD), is an effective therapy for GERD in SSc. The aim of this study was to compare the efficacy of omeprazole in combination with domperidone vs in combination with algycon in reducing the severity and frequency of reflux symptoms of PPI partial response (PPI-PR) GERD in SSc. METHODS: Adult SSc patients having PPI-PR GERD were randomly assigned to receive domperidone plus algycon placebo or algycon plus domperidone placebo in a 1:1 ratio plus omeprazole for 4 weeks. The assessment included severity of symptom grading by visual analogue scale, frequency of symptoms by frequency scale for symptoms of GERD and quality of life (QoL) by EuroQol five-dimensions questionnaire scoring. RESULTS: One hundred and forty-eight SSc-GERD patients were enrolled, of whom 88 had PPI-PR. Eighty cases were randomized for either domperidone (n = 38) or algycon (n = 37) therapy. The majority in both groups had the diffuse SSc subset. At the end of the study, no significant difference in symptom grading was found between groups. After treatment and compared with baseline, the severity of symptoms, frequency scale for symptoms of GERD and QoL significantly improved in both groups. Five (13.2%) and 8 (21.6%) respective cases in the domperidone and algycon groups did not respond. CONCLUSION: The prevalence of PPI-PR GERD is common. Domperidone and algycon are equally effective treatments in combination with omeprazole. However, ∼17% of patients were non-responsive, so the effectiveness of domperidone, algycon and PPI combination therapy should be further investigated.

A significant cancer burden and high mortality of intrahepatic cholangiocarcinoma in Thailand: a nationwide database study.

BACKGROUND: We aimed to examine the burden of intrahepatic cholangiocarcinoma (ICC) in Thailand and identify the prognostic factors for all-causes of death. METHODS: We conducted a population-based study of ICC patients admitted during 2009-2013 using the Nationwide Hospital Admission Database, the National Health Security Office (NHSO). There was an average of 1,051,146 patients/year with diagnosis of gastrointestinal diseases (GI). All patients with a diagnosis of ICC (ICD10- C221) were included from a total of 72,479 admissions from 858 hospitals. The surgical resection procedures such as the radical pancreaticoduodenectomy, subtotal and partial hepatectomy were analyzed. Data for all patients were censored 1 year post-study or death, whichever came first. RESULTS: A total of 34,325 patients with ICC during a 5-year study period (on average, 6865 patients/year, with the incidence rate of 14.6 per 100,000 population, per year. The ICC patients had a mean age of 63.8+/-11.6 years and 63% were males. The mean length of hospital stay was 6.4+/-7.3 days with a mean+/-SD cost of hospitalization of $595+/-$1160 USD per admission. There were 659 patients (1.9%) underwent surgical resection. The overall survival of ICC patients with surgery was significantly better than those patients without surgery. Hazard ratio of death for patients without surgery was 2.5 (95% CI of 2.3-2.7). Approximately 14% of the ICC patients died during hospitalization. The median overall survival of all patients after the first admission was 53 +/-0.6 days. From the multivariate analysis, factors related to all-causes of death were: patients' age >60 years (OR = 1.2, 95% CI; 1.1-1.3), length of hospital stay of >7 days (OR = 1.1, 95% CI; 1.02-1.2), male (OR = 1.3, 95% CI; 1.2-1.4), living in the northern part of Thailand (OR = 1.5, 95% CI; 1.3-1.8) and presence of complications during admission (OR = 1.3, 95% CI; 1.1-1.5). CONCLUSION: The disease burden of patients with ICC in Thailand is significant with the incidence rate of 14.6 per 100,000 population, per year during 2009-2013 and showed high mortality rate of 14%.

Mortality and treatment costs of hospitalized chronic kidney disease patients between the three major health insurance schemes in Thailand.

BACKGROUND: Thailand has reformed its healthcare to ensure fairness and universality. Previous reports comparing the fairness among the 3 main healthcare schemes, including the Universal Coverage Scheme (UCS), the Civil Servant Medical Benefit Scheme (CSMBS) and the Social Health Insurance (SHI) have been published. They focused mainly on provision of medication for cancers and human immunodeficiency virus infection. Since chronic kidney disease (CKD) patients have a high rate of hospitalization and high risk of death, they also require special care and need more than access to medicine. We, therefore, performed a 1-year, nationwide, evaluation on the clinical outcomes (i.e., mortality rates and complication rates) and treatment costs for hospitalized CKD patients across the 3 main health insurance schemes. METHODS: All adult in-patient CKD medical expense forms in fiscal 2010 were analyzed. The outcomes focused on were clinical outcomes, access to special care and equipment (especially dialysis), and expenses on CKD patients. Factors influencing mortality rates were evaluated by multiple logistic regression. RESULTS: There were 128,338 CKD patients, accounting for 236,439 admissions. The CSMBS group was older on average, had the most severe co-morbidities, and had the highest hospital charges, while the UCS group had the highest rate of complications. The mortality rates differed among the 3 insurance schemes; the crude odds ratio (OR) for mortality was highest in the CSMBS scheme. After adjustment for biological, economic, and geographic variables, the UCS group had the highest risk of in-hospital death (OR 1.13;95 % confidence interval (CI) 1.07-1.20; p < 0.001) while the SHI group had lowest mortality (OR 0.87; 95 % CI 0.76-0.99; p = 0.038). The circumscribed healthcare benefits and limited access to specialists and dialysis care in the UCS may account for less favorable comparison with the CSMBS and SHI groups. CONCLUSIONS: Significant differences are observed in mortality rates among CKD patients from among the 3 main healthcare schemes. Improvements in equity of care might minimize the differences.

Prevalence of insomnia and related impact.

Background Sleep problem is a common geriatric condition that can result in various outcomes, both physical and mental, that reduce quality of life. The studies regarding the prevalence and impact of insomnia on daily activities in Thailand in pre-elderly and elderly adults are few. Objectives The primary objective of this study was to determine the prevalence of insomnia among pre-elderly and elderly populations and the secondary objective was to study the impact of insomnia on their daily lives. Methods This study included the participants from the urban middle class in the pre-retirement age of 50 years or older adults who worked for Khon Kaen University (KKU), Khon Kaen, Thailand, and their elderly relatives. Information on baseline characteristics, sleep problems, and outcomes were collected. Descriptive analytical statistics were used to analyze baseline data. Multivariate analysis was used to analyze associated factors of the impact of insomnia. Results A total of 491 participants were recruited. The prevalence of insomnia was 60%. The significant consequences related to insomnia were feeling unrefreshed (adjusted odds ratio (AOD) 2.22, 95% confidence interval (CI) 1.44-3.04), daytime sleepiness (AOD 2.04, 95% CI 1.29-3.22), need for a sedative drug (AOD 4.23, 95% CI 2.09-8.55), depression (AOD 4.74, 95% CI 1.73-13), and impaired attention (AOD 2.29, 95% CI 1.52-3.45). Conclusions Insomnia was found in the majority of pre-elderly and elderly participants and resulted in several poor outcomes. Early detection of insomnia may prevent some inevitable outcomes.

Cost utility analysis of endoscopic biliary stent in unresectable hilar cholangiocarcinoma: decision analytic modeling approach.

BACKGROUND/AIMS: Endoscopic biliary drainage using metal and plastic stent in unresectable hilar cholangiocarcinoma (HCA) is widely used but little is known about their cost-effectiveness. This study evaluated the cost-utility of endoscopic metal and plastic stent drainage in unresectable complex, Bismuth type II-IV, HCA patients. METHODOLOGY: Decision analytic model, Markov model, was used to evaluate cost and quality-adjusted life year (QALY) of endoscopic biliary drainage in unresectable HCA. Costs of treatment and utilities of each Markov state were retrieved from hospital charges and unresectable HCA patients from tertiary care hospital in Thailand, respectively. Transition probabilities were derived from international literature. Base case analyses and sensitivity analyses were performed. RESULTS: Under the base-case analysis, metal stent is more effective but more expensive than plastic stent. An incremental cost per additional QALY gained is 192,650 baht (US$ 6,318). From probabilistic sensitivity analysis, at the willingness to pay threshold of one and three times GDP per capita or 158,000 baht (US$ 5,182) and 474,000 baht (US$ 15,546), the probability of metal stent being cost-effective is 26.4% and 99.8%, respectively. CONCLUSIONS: Based on the WHO recommendation regarding the cost-effectiveness threshold criteria, endoscopic metal stent drainage is cost-effective compared to plastic stent in unresectable complex HCA.

Incidence and Predictors of an Abnormal Liver Function Test Among 674 Systemic Sclerosis Patients: A Cohort Study.

Background: Abnormal liver function tests (LFTs) can indicate cirrhosis or liver cancer leading to mortality among systemic sclerosis (SSc) patients. No recent studies have investigated the clinical predictors of an abnormal LFT in SSc. We aimed to determine the incidence of abnormal LFT (including from hepatitis and cholestasis) and to identify its clinical predictors in SSc patients. Methods: An historical cohort was conducted on 674 adult SSc patients who attended the Scleroderma Clinic, Khon Kaen University, between January 2012 and November 2019 and who underwent routine screening for LFT. A Cox regression was used to analyze the clinical predictors of abnormal LFT. Results: Four hundred and thirty cases, representing 4190 person-years, had abnormal LFTs (viz, from hepatitis, cholestasis, and cholestatic hepatitis) for an incidence rate of 10.2 per 100 person-years. The respective incidence of hepatitis, cholestasis, and cholestatic hepatitis was 20.5, 12.9, and 20.4 per 100 person-years. The respective median first-time detection of hepatitis, cholestasis, and cholestatic hepatitis was 3.0, 5.9, and 2.8 years, and none had signs or symptoms suggestive of liver disease. According to the Cox regression analysis, the predictors of an abnormal LFT in SSc were elderly onset of SSc (hazard ratio (HR) 1.02), alcoholic drinking (HR 1.74), high modified Rodnan Skin Score (mRSS) (HR 1.03), edematous skin (HR 2.94), Raynaud's phenomenon (HR 1.39), hyperCKaemia (HR 1.88), and methotrexate use (HR 1.55). In contrast, current sildenafil treatment (HR 0.63) and high serum albumin (HR 0.70) were protective factors. Conclusion: Occult hepatitis, cholestasis, and cholestatic hepatitis can be detected in SSc patients using LFT screening, especially in cases of early disease onset. The long-term outcome is uncertain, and more longitudinal research is required.

Efficacy of metal and plastic stents in unresectable complex hilar cholangiocarcinoma: a randomized controlled trial.

BACKGROUND: Endoscopic biliary stent drainage is effective in the palliative treatment of patients with hilar cholangiocarcinoma (HCA). However, no randomized controlled trial comparing the efficacy of the self-expandable metal stent (SEMS) and the plastic stent (PS) in patients with unresectable complex HCA is available. OBJECTIVE: To compare the successful drainage rates of endoscopic SEMSs and PSs. DESIGN: A single-center, open-label randomized controlled trial. SETTING: University hospital in KhonKaen, Thailand. PATIENTS: One hundred eight patients with unresectable complex, Bismuth type II-IV HCA. INTERVENTIONS: Endoscopic retrograde cholangiography with unilateral SEMS or PS insertion. MAIN OUTCOME MEASUREMENTS: Successful drainage rate. LIMITATIONS: Diagnosis of HCA was made by clinical presentations, imaging studies, and clinical outcome during follow-up. RESULTS: One hundred eight patients were randomly allocated to the SEMS and PS groups. Intention-to-treat analysis revealed that the successful drainage rate in the SEMS group was higher than in the PS group (70.4% vs 46.3%, P = .011). The median survival times were 126 and 49 days, respectively, in the SEMS and PS groups. The overall survival rates of the patients in both groups were statistically different by log-rank test (P = .002). CONCLUSIONS: Endoscopic biliary drainage with the SEMS provides better adequacy of drainage and longer survival compared with the PS in patients with unresectable complex HCA.

PCR-RFLP and antimicrobial susceptibility profiles of Helicobacter pylori isolated from antrum and corpus of dyspeptic patients in Thailand.

The study determined the genetic heterogeneity of Helicobacter pylori isolates from antrum and corpus of the same dyspeptic patients in a Thai population and determined the relationship between the antimicrobial susceptibility (AS) profile (antibiogram) and PCR-restriction fragment length polymorphism (PCR-RFLP) pattern. One hundred and nineteen H. pylori isolates comprising 7 single and 56 paired antrum and corpus isolates obtained by gastric biopsy from 160 dyspeptic patients were analyzed. For PCR-RFLP, the 820 bp amplicon of ureC was digested with Sau3AI and HhaI, which revealed 16 (A-Q) and 19 (a- s) different PCR-RFLP patterns after Sau3AI and HhaI digestion, respectively. Combination of the restriction enzyme digestion patterns resulted in 35 distinct RFLP types. Among the 56 paired isolates, 47 were infected with H. pylori having the same AS and PCR-RFLP profiles, 7 with different AS profiles but the same PCR-RFLP profiles and 2 with different PCR-RFLP profiles but the same AS profiles. No patient was infected with H. pylori different in both PCR-RFLP and AS profiles. The results indicate that the majority of the paired H. pylori isolates displayed identical AS profile and PCR-RFLP patterns suggesting that most patients were infected with a single strain. Some patients could have been infected with single strains that were different in the AS profiles.

Prevalence of cagA EPIYA motifs in Helicobacter pylori among dyspeptic patients in northeast Thailand.

The aims of this study were to determine the prevalence of cagA type in Helicobacter pylori isolated from dyspeptic patients in northeastern Thailand and to determine whether the pattern of cagA EPIYA motifs were associated with clinical outcomes. One hundred and forty-seven H. pylori-infected dyspeptic patients were enrolled, of whom 68 had non-ulcer dyspepsia (NUD), 57 peptic ulcer disease (PUD), 18 gastric cancer (GCA), and 4 other gastroduodenal diseases. PCR and DNA sequence analysis were used to determine the cagA genotype and the pattern of EPIYA motifs. cagA-positive H. pylori were identified in 138 (94%) of H. pylori-infected dyspeptic patients of whom 75 (54%) were of the Western-type, 44 (32%) the East Asian type and 19 (14%) of the other types. The Western type is significantly found in PUD patients (p = 0.0175). The majority of cagA EPIYA was EPIYA-ABC (43%) and EPIYA-ABD (28%). There is no significant correlation between the increase in number of EPIYA-C motifs and clinical outcomes. Thus, the most frequent cagA type found among northeastern Thai dyspeptic patients was the Western cagA type, which is significantly associated with PUD indicating a possible predictive parameter for clinical outcome.

Disease patterns among Thai adult population: an analysis of data from the hospitalization National Health Insurance System 2010.

BACKGROUND: Disease pattern is an important informational tool used by policymakers in setting priorities, strategies and allocating budgets to address the precursors or causes of health problems. OBJECTIVE: To analyze the common diseases in the adult population using in-patient information from the three health insurance coverage schemes in the fiscal year 2010. MATERIAL AND METHOD: The authors analyzed the data on in-patients with 23 major disease groups as per ICD-10 coding. The data were analyzed to obtain the number of patients, number of admissions, number of hospital mortalities, mortality rates and length of hospital stays. RESULTS: The total number of adult in-patients was 3,876,792 presenting for admission 4,863,935 times. Infectious and parasitic diseases were the most common causes of admission. Diseases of the circulatory system resulted in the highest number of mortality rate (8.72%). Intracerebral hemorrhage, neoplasm, septicemia, liver failure, coronary heart disease, HIV/AIDS, status epilepticus, pneumonia, accidents and acute renal failure were the top ten diseases with a high mortality rate. CONCLUSION: The review indicated communicable diseases are the most common disease group although non-communicable diseases were also important because of their high mortality rate.

Hospitalized incidence and outcomes of upper gastrointestinal bleeding in Thailand.

BACKGROUND: Upper gastrointestinal bleeding (UGIB) is a common emergency gastrointestinal problem which has substantial mortality and health care resources use. The nationwide basic information on UGIB is not available in Thailand. OBJECTIVE: To identify the hospitalized incidence, outcomes and hospitalization cost of patients who presented with UGIB in Thailand. MATERIAL AND METHOD: Information on illness of in-patients from hospitals nationwide was retrieved from three major health schemes database in fiscal year 2010. RESULTS: The hospitalized incidence rate of UGIB was 166.3 admissions per 100,000 populations and the hospitalized incidence rate of non-variceal upper gastrointestinal bleeding (NVUGIB) and variceal bleeding were 152.9 and 13.5 admissions per 100,000 populations respectively. Endoscopic procedure was undertaken in 27.6% of NVUGIB admissions and 80.7% of variceal bleeding admissions. The in-hospital mortality rate, hospitalization cost and length of stay were higher in variceal bleeding patients compared with NVUGIB patients. CONCLUSION: UGIB is an important emergency gastrointestinal problem which has significant mortality and substantial health care resources consumption.

Health insurance system and healthcare provision: nationwide hospital admission data 2010.

BACKGROUND: The three major health insurance systems are different in their medical service coverage, reimbursement process and choice of providers; leading to the question of how great are the variations in the healthcare offered and disease outcomes. OBJECTIVE: To assess whether differences exist and to analyze the effects of on healthcare provision and disease outcomes in the adult population across the three health insurance systems. MATERIAL AND METHOD: The authors analyzed the disease outcomes of the 23 major ICD-10 disease groups among the three major health insurance systems to obtain the death rates, levels of healthcare provision and the hospital charges. Factors influencing mortality rates were evaluated by multiple logistic regression analysis. RESULTS: The community, general, tertiary care and private hospitals provided hospitalization for 41.4%, 22%, 27.3% and 9.3% of hospitalized adult patients, respectively. Infectious & parasitic diseases were the most common causes of admissions. Disease of the digestive system was the most common cause of admission in general hospitals while malignancy was the most common in the tertiary care hospitals. Patients with congenital malformation, neoplasm, mental and behavioral disorder and diseases of the eye were commonly treated at tertiary care hospitals. The mean and median of hospital charges were highest in the Civil Servant Medical Benefit System (CSMBS) (26,668; 10,209 Baht), followed by the Social Security System (SSS) (21,455; 9,713 Baht) and the Universal Coverage System (UC) (13,086; 5,246 Baht). The respective overall mortality rates for the CSMBS, SSS and UC were 4.40%, 1.38% and 3.32%. After adjustment, however a significant association between UC and mortality was found with an odds ratio of 1.43 (1.40-1.45) as compared to CSMBS. In addition, other factors most influencing mortality rates were male sex, elderly age, and the levels of healthcare. CONCLUSION: The differences in charges for some groups of diseases and significantly different clinical outcomes across schemes existed. The differences in disease outcomes were not adjusted for socioeconomic status and disease severity, requiring a cautious interpretation; nevertheless, an association with a higher mortality rate under the UC scheme for inpatient services need prompt further study

Regional Differences in Admissions and Treatment Outcomes for Hepatocellular Carcinoma Patients in Thailand.

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the commonest cancers in Thailand. We report the stage and survival of patients who were admitted under the public universal health fund (NHSO) covering 47 million people to determine if there were regional disparities in the treatment outcomes in the country. METHOD: We used the 2009-2013 Nationwide Hospital Admission Data, Thailand. Patients with hepatocellular carcinoma (HCC) were identified by the ICD10 code C22.0. Procedures were identified by ICD9-CM codes, and deaths were confirmed from the NHSO database and the national citizen registry. Thailand is divided into 6 regions and Bangkok. Hospitals were identified according to their specific reimbursement codes. Survival time started from the day of first admission and was estimated using the Kaplan-Meier method. The statistical method used to compare regions was Chi-squared tests (Pearson, likelihood ratio, linear-by linear association and Mantel-cox). RESULTS: There were 36,956 HCC patients admitted during the study period. The overall median survival was 36 days. 1.63% of the patients had surgery, 0.96% had radiofrequency ablation (RFA), and 5.24% had trans-arterial chemoembolization (TACE). 90.24% did not have any tumor-specific therapy. The proportion of patients admitted for tumor-specific therapy vs. no tumor-specific therapy was significantly different between regions in all treatment modalities (p<0.01). Each treatment modality showed a wide range of median survival values across the regions (p<0.01). The best survival was seen in Bangkok, the South and the North (for surgery, RFA and TACE) and was often more than twice as long as the regions with the lowest survival, Central, East and West. CONCLUSIONS: There was a large previously-unreported disparity in admissions and outcomes in Thailand for different treatment modalities for HCC. Bangkok and the South had the best treatment outcomes and often had median survivals more than twice as long as those in the West and East. Public policy to reduce this disparity will need to be implemented in the future.

Nested polymerase chain reaction for detection of Helicobacter pylori in gastric biopsy specimens.

Sensitivity and specificity are important for tests used to defect Helicobacter pylori infection from gastric biopsy specimens. Molecular methods, such as PCR and nested PCR, are sensitive methods for H. pylori detection. The objective of this study was to evaluate the performance of PCR and nested PCR compared to culture, the rapid urease test (RUT) and histology for the diagnosis of H. pylori in 130 gastric biopsy specimens from symptomatic dyspeptic patients. Sensitivity and specificity with PCR were 91 and 100% and with nested PCR were 95 and 97%, respectively. H. pylori was detected by PCR and nested PCR at levels as low as 125 fg (70 cells) and 25 fg (14 cells), respectively. These results suggest nested PCR is a highly sensitive direct method to detect H. pylori infection from biopsy specimens.

Prevalence and predictors of proton pump inhibitor partial response in gastroesophageal reflux disease in systemic sclerosis: a prospective study.

Proton pump inhibitor (PPI) twice daily dosing is a standard therapy for gastroesophageal reflux disease (GERD) in systemic sclerosis (SSc) but there is no data on its response rate or the predictors of PPI-partial response GERD. Aims were to determine the prevalence of PPI-partial response GERD in SSc and to define its predictors. A prospective study was conducted in SSc patients with GERD. The patients were treated with omeprazole 20 mg bid for 4 weeks. The severity of symptom-grading by visual analogue scale (VAS) and frequency of symptoms by frequency scale for symptoms of GERD (FSSG) were assessed at baseline and 4 weeks after treatment. PPI-partial response GERD was defined as less than 50% improvement in the VAS for severity of symptom as well as acid reflux score by FSSG after treatment. According to the sample size calculation, 243 SSc-GERD patients were enrolled; of whom 166 (68.3%) had the diffuse cutaneous SSc. PPI-partial response GERD was found in 131 SSc patients (prevalence 53.9%; 95%CI 47.4-60.3). The multivariate analysis revealed that esophageal dysphagia was an only predictor the PPI-partial response GERD (OR 1.82; 95%CI 1.01-3.29) while neither SSc subset nor severity of skin tightness were significantly associated with PPI-partial response GERD. Half of the SSc patients were PPI-partial response GERD. Esophageal dysphagia was the only predictor of PPI-partial response GERD in SSc patients. Screening for dysphagia before starting GERD treatment is helpful for assessment the risk of PPI refractoriness GERD in SSc patients.

Prevalence and associated factors of small intestinal bacterial overgrowth among systemic sclerosis patients.

BACKGROUND: Small intestinal bacterial overgrowth (SIBO) results in nutrient malabsorption and malnutrition, thereby increasing the morbidity and mortality in systemic sclerosis (SSc) patients. OBJECTIVES: To evaluate the prevalence and associated factors of SIBO in SSc patients. METHOD: A cross-sectional study was conducted between July 2015 and January 2016 in SSc patients over 18, using the glucose H2 /CH4 breath test to evaluate SIBO. RESULTS: Eighty-nine SSc patients (30 male and 59 female) underwent the glucose H2 /CH4 breath test. The mean age was 54.4. Twelve participants were positive for the glucose H2 /CH4 breath test, yielding a SIBO prevalence of 13.5% (95% CI 7.2-22.4) among SSc patients. A multivariate analysis revealed that duration of disease >5 years was significantly associated with SIBO (adjusted odds ratio 9.38; 95% CI 1.09-80.47). CONCLUSION: The prevalence of SIBO, using the glucose H2 /CH4 breath test, is not common among Thai SSc patients. However, a positive result was associated with longer duration of disease.

Thailand Dyspepsia Guidelines: 2018.

The management of dyspepsia in limited-resource areas has not been established. In 2017, key opinion leaders throughout Thailand gathered to review and evaluate the current clinical evidence regarding dyspepsia and to develop consensus statements, rationales, levels of evidence, and grades of recommendation for dyspepsia management in daily clinical practice based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. This guideline is mainly focused on the following 4 topics: (1) evaluation of patients with dyspepsia, (2) management, (3) special issues (overlapping gastroesophageal reflux disease/irritable bowel syndrome and non-steroidal anti-inflammatory drug/aspirin use), and (4) long-term follow-up and management to provide guidance for physicians in Thailand and other limited-resource areas managing such patients.
