RESUMEN
Gastroesophageal reflux disease (GERD) is one of the most prevalent and bothersome functional gastrointestinal disorders worldwide, including in Thailand. After a decade of the first Thailand GERD guideline, physician and gastroenterologist encountered substantially increase of patients with GERD. Many of them are complicated case and refractory to standard treatment. Concurrently, the evolution of clinical characteristics as well as the progression of investigations and treatment have developed and changed tremendously. As a member of Association of Southeast Asian Nations, which are developing countries, we considered that the counterbalance between advancement and sufficient economy is essential in taking care of patients with GERD. We gather physicians from university hospitals, as well as internist and general practitioners who served in rural area, to make a consensus in this updated version of GERD guideline focusing in medical management of GERD. This clinical practice guideline was constructed adhering with standard procedure. We categorized the guideline in to four parts including definition, investigation, treatment, and long-term follow up. We anticipate that this guideline would improve physicians' proficiency and help direct readers to choose investigations and treatments in patients with GERD wisely. Moreover, we wish that this guideline would be applicable in countries with limited resources as well.

GOALS: To assess the effect of unilateral versus bilateral lung transplantation (LTx) on esophageal motility and gastroesophageal reflux, and the association with the development of obstructive chronic lung allograft dysfunction (o-CLAD). BACKGROUND: We have shown that esophagogastric junction outflow obstruction, incomplete bolus transit, and proximal reflux are all independent risk factors for the development of chronic allograft failure. However, it remains unclear whether these factors are influenced by the type of surgery and how this relates to allograft failure. STUDY: Patients post-LTx (n=48, 24 female; aged 20 to 73 y) completed high-resolution impedance manometry and 24-hour pH/impedance. RESULTS: Patients who had undergone unilateral LTx were more likely to exhibit esophagogastric junction outflow obstruction (47% vs. 18%; P=0.046) and less likely to exhibit hypocontractility (0% vs. 21%; P=0.058) than those who had undergone bilateral LTx. Although the proportion of patients exhibiting gastroesophageal reflux was no different between groups (33% vs. 39%; P=0.505), those undergoing bilateral LTx were more likely to exhibit proximal reflux (8% vs. 37%; P=0.067). Univariate Cox proportion hazards regression analysis did not show a difference between unilateral versus bilateral LTx in the development of o-CLAD (hazard ratio=1.17; 95% confidence interval, 0.48-2.85; P=0.723). CONCLUSION: The type of LTx performed seems to lead to different risk factors for the development of o-CLAD. Physicians should be aware of these differences, as they may need to be taken into account when managing patient's post-LTx.

BACKGROUND: Post-embolization syndrome is a common complication after transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). N-acetylcysteine (NAC) is known to ameliorate liver damage from several causes. AIM: To determine the efficacy of intravenous NAC in the prevention of post-embolization syndrome in HCC patients following TACE. METHODS: In this study, patients with HCC admitted for TACE were prospectively enrolled. All patients were randomized stratified by Child A or B to receive NAC or placebo. The NAC group received intravenous NAC 24 h prior to TACE (150 mg/kg/h for 1 h followed by 12.5 mg/kg/h for 4 h, then continuous infusion 6.25 mg/h for 48 h after the procedure). The placebo group received an infusion of 5% glucose solution until 48 h after procedure. The post-embolization syndrome was defined as: T ≥ 38.5 c and serum ALT > 3 times of pretreatment value. RESULTS: In total, 111 HCC patients were enrolled; 57 were randomly assigned to NAC group and 54 to placebo group. The incidence of post-embolization syndrome was lower in NAC group (24.6%) compared to placebo group (48.2%); P = 0.01. On multivariate analysis, receiving IV NAC (P = 0.03) and HCC diameter (P < 0.01) were associated with developing post-embolization syndrome. Post-TACE liver decompensation was documented in 26/111 (23.4%) patients. There was no difference in the incidence of post-TACE liver decompensation between NAC and placebo group. CONCLUSIONS: In this study, intravenous NAC administration reduces the incidence of post-embolization syndrome after TACE in patients with HCC. However, it does not prevent post-TACE liver decompensation. TRIAL REGISTRATION NUMBER: This study was registered with Thai Clinical Trial Registry (TCTR20150313002).

Background: In some hospitals, patients hospitalized on the medical ward are mechanically ventilated due to a shortage of intensive care unit (ICU) beds.. Objective: To determine outcomes and prognostic factors of medical patients mechanically ventilated on general medical wards. Material and Method: A prospective observational study was performed in general medical wards of a 2,000-bed tertiary care university hospital. Results: Ninety-three consecutive medical patients who were mechanically ventilated on a general medical ward were included in the study. Overall mortality rate of patients mechanically ventilated on the general medical ward was 68.8%. Average length of stay was 22.9±28.5 days. Average cost per patient was 61,076.64±87,569.10 Thai baht. In univariate analysis, the APACHE II score of the patients who did not survive was significantly higher than the score of the patients who survived (mean APACHE II score 23.3±7.3 vs. 19.8±5.5 respectively, p = 0.02). Multivariate analysis revealed APACHE II score >22 to be the only independent predictor of death (OR 4.3, 95% CI 1.2-15.2, p = 0.02). Conclusion: Medical patients who are mechanically ventilated on general medical wards have high mortality rate. APACHE II score is a good prognostic factor for predicting risk of death in these patients

OBJECTIVES: Gastroesophageal reflux is common in patients post-lung transplantation (LTx) and thus considered a risk factor for aspiration and consequently allograft rejection and the development of chronic allograft failure. However, evidence supporting this remains unclear and often contradictory. Our aim was to examine the role played by esophageal motility on gastroesophageal reflux exposure, along with its clearance and that of boluses swallowed, and the relationship to development of obstructive chronic lung allograft dysfunction (o-CLAD). METHODS: Patients post-LTx (n=50, 26 female; mean age 55 years (range, 20-73 years)) completed high-resolution impedance manometry and 24-h pH/impedance. Esophageal motility abnormalities were classified based upon the Chicago Classification version 3.0. RESULTS: Esophagogastric junction outflow obstruction alone (EGJOOa) (P=0.01), incomplete bolus transit (IBT) (P=0.006) and proximal reflux (P=0.042) increased the risk for o-CLAD. Patients with EGJOOa were most likely to present with o-CLAD (77%); despite being less likely to exhibit abnormal numbers of reflux events (10%) compared with those with normal motility (o-CLAD: 29%, P<0.05; abnormal reflux events: 64%, P<0.05). Patients with EGJOOa had lower total reflux bolus exposure time than those with normal motility (0.6 vs. 1.5%; P<0.05). In addition, poor esophageal clearance documented by abnormal post-reflux swallow-induced peristaltic wave index associated with o-CLAD; inversely correlating with the proportion of reflux events reaching the proximal esophagus (r=-0.251; P=0.052). CONCLUSIONS: These observations support esophageal dysmotility, especially EGJOOa, and impaired clearance of swallowed bolus or refluxed contents, more so than just the presence of gastroesophageal reflux alone, as important risk factors in the development of o-CLAD.
RESUMEN
BACKGROUND: Studies of effects of IL-1 polymorphisms, CYP2C19 genotype together with antibiotic resistance for H. pylori eradication are rare worldwide. The present study was designed to evaluate efficacy of 10-day sequential therapy (SQT) and 14-day standard triple therapy (STT) with four- times-daily dosing of amoxicillin for H. pylori eradication related to these important host and bacterial factors in Thailand. MATERIALS AND METHODS: This prospective randomized study was performed during March 2015 to January 2016. H. pylori infected gastritis patients were randomized to receive 10-day sequential therapy and 14-day standard triple therapy. CYP2C19 genotyping, IL1 polymorphism (IL-1B and IL-1RN genotypes) and antibiotic susceptibility tests were performed in all patients. 13C-UBT was conducted to confirm H. pylori eradication at least 4 weeks after treatment. RESULTS: A total of 100 patients (33 males and 67 females, mean age=51.1 years) were enrolled. Eradication rate by PP analysis was 97.9% (47/48) with the 10-day SQT regimen and 87.8% (43/49) with 14-day STT regimen (97.9% vs 87.8%; p-value=0.053). Antibiotic susceptibility testing demonstrated 45% resistance to metronidazole, 14.8% to clarithromycin, and 24.1% to levofloxacin. CYP2C19 genotyping revealed 44.9% RM, 49% IM and 6.1% PM. IL-1B and IL-1RN genotypes were demonstrated as 21.4% for CC, 48.1% for TC, 36.8% for TT, 72.7% for 1/1, and 21.2% for 1/2 genotypes, respectively. The 10-day SQT regimen provided 100% eradication in patients with clarithromycin or dual clarithromycin and levofloxacin H. pylori resistant strains. Moreover, the 10-day SQT regimen resulted in a 100% eradication rate in all patients with CYP2C19 genotype RM and almost type of IL-1B (TC and TT) and IL1-RN genotypes ( 1/2 and other). CONCLUSIONS: Treatment with 10-day sequential therapy is highly effective for H. pylori eradication regardless of the effects of clarithromycin resistance, dual clarithromycin and levofloxacin resistance, CYP2C19 genotype, IL-1B and IL1-RN genetic polymorphisms and can be used as effective first line therapy in Thailand.

BACKGROUND: Chronic hepatitis B virus (HBV) infection related hepatocellular carcinoma (HCC) is a major health problem in the Asia-Pacific region including Thailand. Several factors have been proposed as contributing to hepatocarcinogenesis. This study was aimed to investigate the impact of CYP2C19 genotypic polymorphism in HCC related to chronic HBV infection in Thailand. MATERIALS AND METHODS: A cross-sectional study was performed between April 2014 and January 2015. Chronic HBV patients with HCC (n=50) and without HCC (n=50) were included. Clinical information and blood samples of all patients were collected. The CYP2C19 genotype was determined by polymerase chain reaction-restriction fragment length polymorphism method, and was classified as rapid metabolizer (RM), intermediate metabolizer (IM) or poor metabolizer (PM). RESULTS: The CYP2C19 genotype frequencies of RM, IM and PM in HBV patients were found to be 19/50 (38%), 25/50 (50%) and 6/50 (12%), respectively. The CYP2C19 genotype frequencies of RM, IM and PM in HBV with HCC patients were 21/50 (42%), 25/50 (50%) and 4/50 (8%), respectively. The distribution of CYP2C19 genotype was not different between patients with and without HCC. Interestingly, among HBV with HCC patients, the RM genotype of CYP2C19 tended to increase risk of aggressive manifestation (OR=2.89, 95%CI=0.76-11.25, P-value = 0.07), compared with non RM genotype carriers. CONCLUSIONS: CYP2C19 genotype IM was the most common genotype in Thai patients with chronic HBV infection. In addition, genotype RM could be an associated factor for aggressive presentation in HCC related to chronic HBV infection.

BACKGROUND: Helicobacter pylori (H. pylori) is a well known major cause of gastric cancer and even when asymptomatic infected patients are at elevated risk. Functional dyspepsia (FD) is also one of the most common gastrointestinal diseases, which greatly impacts the quality of life. H. pylori infection and psychosocial stress are frequently associated with FD but limited studies have confirmed the relationships, especially in Southeast Asian countries. Here we aimed to investigate the prevalence and impact of H. pylori infection, anxiety and depression on Thai FD patients. MATERIALS AND METHODS: This cross-sectional study was conducted in a tertiary care center in Thailand, during February 2013-January 2014. All FD patients were diagnosed and categorized by Rome III criteria into epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS) groups. The Hospital Anxiety and Depression Scale was used to evaluate psychological status. The presence of H. pylori was defined as positive with H. pylori culture, positive rapid urease test or positive histology. RESULTS: Three hundred FD patients were included, 174 (58%) female. Overall mean age was 54.8+15.1 years. There were 192 (64%) patients with PDS and 108 (36%) with EPS. H. pylori infection was demonstrated in 70 (23.3%) patients. Anxiety and depression were documented in 69 (23%) and 22 (7.3%), respectively. H. pylori infection, anxiety and depression were significantly higher in PDS than EPS patients (27.1% vs 16.7%; p=0.04; OR=1.86; 95%CI=1.01-3.53 and 29.7% vs 11.1%; p=0.0002; OR=3.4; 95%CI=1.7-7.1 and 10.4% vs 1.9%; p=0.006; OR=6.2; 95%CI=1.4-38.9, respectively). CONCLUSIONS: H. pylori infection, anxiety and depression were commonly found in Thai FD patients and more prevalent in PDS than EPS. H. pylori eradication might be the key to success for the treatment of Thai FD patients and prevent the development of gastric cancer.
