Hood attached vs conventional triangular tip-jet knife in peroral endoscopic myotomy: a propensity score matching cohort study.

BACKGROUND & AIM: Peroral endoscopic myotomy (POEM) is a safe and effective endoscopic treatment for achalasia and other esophageal motility disorders, and TTJ (Triangle Tip Knife J; Olympus, Tokyo, Japan) is currently widely used in POEM. Recently, we reported a novel modification of TTJ, which was adjusted to knife length 2 mm by attaching a disposable clip (QuickClip Pro; Olympus) sheath to the tip as a hood attachment. In this study, we compared the safety and effectiveness of TTJ and TTJ with hood attachment (TTJ-H) in POEM. METHODS: In this 1:1 propensity score matched retrospective cohort study, we compared the procedure time, myotomy efficiency, number of coagulation forceps usage, adverse events, length of hospital stay after POEM, procedural success and clinical success between TTJ and TTJ-H groups. RESULTS: We examined 682 consecutive patients who underwent POEM between January 2021 and June 2023. We excluded 134 patients who had already undergone POEM or laparoscopic Heller myotomy as prior myotomy. Finally, we identified 98 propensity score-matched pairs (n = 196). The mean procedure time was shortened from 93.5 to 80.2 min (14% reduction, P = 0.012) when comparing TTJ-H group to TTJ group. The mean myotomy efficiency was improved from 2.76 to 2.32 min/cm (16% improvement, P = <0.001), and usage of coagulation forceps for hemostasis was decreased from 3.87 to 0.55 (86% reduction, P = <0.001). CONCLUSIONS: This study showed that use of TTJ-H could reduce total procedure time, improve myotomy efficiency, and reduce costs compared to TTJ.

Thailand guideline 2020 for medical management of gastroesophageal reflux disease.

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.

Diagnostic performance of endoscopic ultrasound-guided tissue acquisition by EUS-FNA versus EUS-FNB for solid pancreatic mass without ROSE: a retrospective study.

BACKGROUND: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) is an established diagnostic procedure for solid pancreatic mass. However, the diagnostic yield between fine-needle aspiration (FNA) and fine-needle biopsy (FNB) remains unclear. We aimed to evaluate and compare the diagnostic yields between FNA and FNB using conventional FNA and Franseen needles of the same size 22-gauge needle, in patients with solid pancreatic mass who underwent EUS-TA without rapid onsite cytopathology evaluation (ROSE). METHODS: All cases of EUS-TA by FNA or FNB for solid pancreatic mass between January 2017 and October 2020 in a single-centre university hospital were retrospectively reviewed. All procedures were performed without an onsite cytologist. Before the endoscopist finished the procedure, macroscopic onsite evaluation (MOSE) was confirmed. The diagnostic yield and the average number of needle passes between FNB and FNA were then compared. RESULTS: A total of 151 patients (FNA, n = 77; FNB, n = 74) with solid pancreatic mass detected by cross-sectional imaging underwent EUS-TA. The mean age was 62.3 ± 12.8 years, with 88 (58.3%) males. Age, sex, mass location, tumour size and disease stage from imaging were not significantly different between the two groups. The diagnostic performance was higher in EUS-FNB (94.6%) than in EUS-FNA (89.6%). The mean number of needle passes was clearly fewer in FNB than in FNA (2.8 vs. 3.8, p < 0.001). The total procedure time was shorter in FNB (34.7 min) than in FNA (41 min). The adverse event rate between FNB and FNA was not significantly different. CONCLUSIONS: The diagnostic yield of solid pancreatic mass was higher in FNB using the Franseen needle than in FNA using the conventional FNA needle in a centre where ROSE is unavailable, without serious adverse event. In addition, FNB had fewer needle passes and shorter total procedure time.

Efficacy of prucalopride in critically ill patients with paralytic ileus: A pilot randomized double-blind placebo-controlled trial.

BACKGROUND AND AIM: Paralytic ileus is a common intestinal dysfunction in critically ill patients, which results in complications and poor hospital outcomes. There are still no established effective medications, except correcting the primary causes and prokinetics trial, which have limited efficacy and potential adverse events. This study aims to evaluate the efficacy of prucalopride on paralytic ileus in critically ill patients. METHODS: A randomized, double-blind, placebo-controlled trial of five consecutive days treatment periods was conducted. Critically ill patients with paralytic ileus were included. The primary endpoint was the improvement of bowel dilatation on plain abdominal radiography. The secondary endpoint was the change of abdominal circumference. RESULTS: Twenty patients were consecutively enrolled in the study. There was no significant difference in baseline characteristics of patients. The common causes of hospitalization were infection and respiratory problems. The maximum large bowel diameters dramatically decreased in prucalopride group and reached maximum point on the third day after intervention when compared with placebo (-2.1 [± 1.8] vs 0.3 [± 1.5] cm, P = 0.01). The maximum small bowel diameters were noticeably less decreased and were not significantly different when compared with placebo. The abdominal circumferences notably decreased and significantly diverged from placebo on the third day. CONCLUSIONS: Prucalopride was an effective enterokinetic agent to improve non-severe inflammatory/ischemic bowel conditions related paralytic ileus in critically ill patients. Its effect was predominant on large intestine but could not be well demonstrated on small bowel in this study. Future study or concomitant other prokinetics for upper gut motility should be further evaluated.

Hepatitis B surface antigen, core-related antigen and HBV RNA: Predicting clinical relapse after NA therapy discontinuation.

BACKGROUND & AIMS: The safe discontinuation of nucleos(t)ide analogue therapy remains challenging in chronic hepatitis B. We investigated the potential role of quantitative hepatitis B surface antigen, hepatitis B core-related antigen and hepatitis B virus RNA at the end of treatment in predicting off-therapy relapse. METHODS: Patients who fulfilled the stopping criteria of the Asian Pacific Association for the Study of the Liver guideline were enrolled. Virological relapse was defined as hepatitis B virus DNA level greater than 2000 IU/mL, and clinical relapse was defined as virological relapse plus alanine aminotransferase level of more than twice the upper limit of normal. RESULTS: Ninety-two patients participated. The combination of end-of-treatment hepatitis B core-related antigen and hepatitis B virus RNA levels was most predictive of clinical relapse. Multivariate analysis revealed that end-of-treatment hepatitis B core-related antigen and hepatitis B virus RNA were independently associated with clinical relapse. During follow-up, no patients with undetectable hepatitis B core-related antigen (<3.0 log10 U/mL) and hepatitis B virusRNA (<2.0 log10 copies/mL) at end of treatment developed clinical relapse, in comparison with 22.9% and 62.5% patients with detectable levels of one or both biomarkers respectively. End-of-treatment quantitative hepatitis B surface antigen was linked to a likelihood of hepatitis B surface antigen clearance. CONCLUSIONS: The combined hepatitis B core-related antigen and hepatitis B virus RNA assays at end of treatment were highly predictive of subsequent clinical relapse. These novel biomarkers could potentially be used to identify patients who could safely discontinue nucleos(t)ide analogue therapy.

A Study of Plasma Zinc Levels in Thais with Alopecia Areata.

Objective: To study the correlation between the plasma zinc levels of Thai participants with alopecia areata (AA) and compare to the levels of Thais who do not have AA. Material and Method: A cross-sectional study of thirty Thais with AA (case group) and thirty gender and age-matched healthy subjects (control group). All participants underwent blood tests measuring zinc and confounding factors. Results: Participants in both groups were the same gender, 20 (66.7%) women and 10 (33.3%) men. The median age was 37 in the study group and 38 in the control. In the study group, the median disease duration was three months (interquartile range 1-6). Patients who had AA for more than three months had a lower mean plasma zinc level than those who had AA for less than three months without statistical significance (58.33±8.59, 62.43±13.19 µg/dL (mean ± standard deviation or SD), respectively, p-value = 0.40). The correlation between plasma zinc levels and disease duration of AA (p-value = 0.31) and the plasma zinc levels and the Severity of Alopecia Tool (SALT) score (p-value = 0.16) were not statistically significant. The mean plasma zinc level in the study group was lower than in the control group with statistical significance (61.20±12.00, 67.17±10.04 µg/dL (mean ± SD), respectively, p-value = 0.04). Conclusion: The plasma zinc level in participants with AA is statistically significantly lower than in participants without AA. A more in depth study should be conducted to determine whether prescribing zinc supplement would be of benefit to AA patients.

Efficacy of Vonoprazan vs. Intravenous Proton Pump Inhibitor in Prevention of Re-Bleeding of High-Risk Peptic Ulcers: A Randomized Controlled Pilot Study.

Background: Proton pump inhibitor (PPI) therapy is well-established for its effectiveness in reducing re-bleeding in high-risk peptic ulcer patients following endoscopic hemostasis. Vonoprazan (VPZ) has demonstrated the capacity to achieve gastric pH levels exceeding 4, comparable to PPIs. This study aims to evaluate the comparative efficacy of intravenous PPI infusion versus VPZ in preventing re-bleeding after endoscopic hemostasis in patients with high-risk peptic ulcers. Methods: A randomized, double-blind, controlled, and double-dummy design was employed. Patients with peptic ulcer bleeding (Forrest class IA/IB or IIA/IIB) who underwent endoscopic hemostasis were randomly assigned to either the PPI group or the VPZ group. Re-bleeding rates at 3, 7, and 30 days, the number of blood transfusions required, length of hospitalization, and ulcer healing rate at 56 days were assessed. Results: A total of 44 eligible patients were enrolled, including 20 patients (PPI group, n = 11; VPZ group, n = 9) with high-risk peptic ulcers. The mean age was 66 years, with 70% being male. Re-bleeding within 72 h occurred in 9.1% of the PPI group versus 0% in the VPZ group (p = 1.000). There was no significant difference in re-bleeding rates within 7 days and 30 days (18.2% vs. 11.1%, p = 1.000). Additionally, the ulcer healing rate did not significantly differ between the groups (87.5% vs. 77.8%). Conclusions: This pilot study demonstrates comparable efficacy between oral vonoprazan and continuous PPI infusion in preventing recurrent bleeding events among high-risk peptic ulcer patients following successful endoscopic hemostasis.

FAIL-T (AFP, AST, tumor sIze, ALT, and Tumor number): a model to predict intermediate-stage HCC patients who are not good candidates for TACE.

Background: Patients with un-resectable hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) are a diverse group with varying overall survival (OS). Despite the availability of several scoring systems for predicting OS, one of the unsolved problems is identifying patients who might not benefit from TACE. We aim to develop and validate a model for identifying HCC patients who would survive <6 months after their first TACE. Methods: Patients with un-resectable HCC, BCLC stage 0-B, who received TACE as their first and only treatment between 2007 and 2020 were included in this study. Before the first TACE, demographic data, laboratory data, and tumor characteristics were obtained. Eligible patients were randomly allocated in a 2:1 ratio to training and validation sets. The former was used for model development using stepwise multivariate logistic regression, and the model was validated in the latter set. Results: A total of 317 patients were included in the study (210 for the training set and 107 for the validation set). The baseline characteristics of the two sets were comparable. The final model (FAIL-T) included AFP, AST, tumor sIze, ALT, and Tumor number. The FAIL-T model yielded AUROCs of 0.855 and 0.806 for predicting 6-month mortality after TACE in the training and validation sets, respectively, while the "six-and-twelve" score showed AUROCs of 0.751 (P < 0.001) in the training set and 0.729 (P = 0.099) in the validation sets for the same purpose. Conclusion: The final model is useful for predicting 6-month mortality in naive HCC patients undergoing TACE. HCC patients with high FAIL-T scores may not benefit from TACE, and other treatment options, if available, should be considered.

Evaluating the impact of position, volume, and consistency on high-resolution esophageal manometry outcomes.

BACKGROUND: The Chicago classification primarily utilizes ten 5 mL liquid swallows in a supine position as the standard high-resolution esophageal manometry (HRM) protocol. HRM can be performed with varying volumes and consistencies and in an upright position. We aimed to determine the impact on HRM results by (1) position, (2) swallows of differing volume and consistency, and (3) perception of bolus passage. METHODS: HRM was performed in healthy volunteers (HV) with the following protocol of swallows: liquids 10 × 5 mL, 5 × 10 mL, and 3 × 10 mL multiple rapid swallows; applesauce 5 × 5 mL and 5 × 10 mL; and bread 5 × 2 × 2 cm and 5 × 4 × 4cm. HV rated difficulty of each swallow on a 5-point Likert scale. All HVs performed the protocol in supine position first and then in "semi-upright" (sitting 70 degrees in a bed) and "upright" (sitting in a chair) in a randomized order. KEY RESULTS: Thirty-seven HVs, median age 27 years, 64% female completed this study. Median distal contractile integral (DCI) and integrated relaxation pressure 4 s (IRP4) of 5 mL liquid swallows significantly differed (all p < 0.01) between position performed. Large volume swallows resulted in higher DCI and lower IRP4. IRP4 results were significantly increased for 2 × 2 cm pieces of bread compared to 5 mL water swallows. DCI results were higher for 2 × 2 cm pieces of bread compared to 5 mL water swallows. Distal latency was shorter in more upright positions. Among this cohort of HV, perceived difficulty of bolus passage was more likely to occur with solid boluses. CONCLUSIONS AND INFERENCES: The volume and consistency of a swallow and the position it is performed in, significantly alter HRM metrics. Interpretation of HRM studies should incorporate different normative values which are specific to the position and bolus type.

Concise Review: Applicability of High-resolution Manometry in Gastroesophageal Reflux Disease.

Manometry, particularly high-resolution manometry is the preferred diagnostic tool used to evaluate esophageal motor function. This investigation is strongly indicated in the setting of dysphagia, but is also useful in gastroesophageal reflux disease (GERD), especially in case of failure of conventional treatment to exclude alternative diagnoses and prior to anti-reflux surgery. Moreover, ineffective esophagogastric junction barrier function and esophageal motor dysfunction are pathophysiological mechanisms in GERD and can be identified by manometry. The recent international guidelines have positioned high-resolution manometry as an important part of functional diagnostic work up in GERD in order to identify the GERD phenotype to guide specific treatment. The proposed manometric identification and measurement is based on the Chicago classification version 4.0 adding with new established metrics for GERD evaluation.

The use of Andrographis paniculata and its effects on liver biochemistry of patients with gastrointestinal problems in Thailand during the COVID-19 pandemic: a cross sectional study.

In the COVID-19 pandemic, healthcare facility supply and access are limited. There was an announcement promoting Andrographis paniculata (ADG) use for treatment of mild COVID-19 patients in Thailand, but misconception of taking for prevention might occur. Moreover, the effect of ADG on liver function test (LFT) has not been established. To study the ADG use and effect on LFT in patients with gastrointestinal (GI) problems, conducted a cross-sectional study including GI patients who voluntarily filled the ADG questionnaire in Aug-Sep 2021. LFT data at that visit and at the prior visit (if available) were obtained. The changes in LFT within the same person were analyzed and compared between patients with and without ADG consumption. During the study period, a total of 810 patients completed the survey, 168 patients (20.7%) took ADG within the past month. LFT data were available in 485 (59.9%) patients, the median alanine aminotransferase (ALT)  change compared with the prior visit was higher in the ADG vs control group (+ 2 vs 0, p = 0.029), and 44.5% had increased ALT (> 3 U/L) vs 32.2% in the ADG and control group, respectively (p = 0.018). Factors independently associated with an increased ALT, from a multivariable logistic regression, were ADG exposure (adjusted OR 1.62, p = 0.042), and patients with NAFLD who gained weight (adjusted OR 2.37, p = 0.046). In conclusion, one-fifth of GI patients recently took ADG, even it is not recommended for COVID-19 prevention. Those who took ADG are more likely to experience an increased ALT than who did not. The potential risk of ADG consumption on liver function should be further assessed.

Diagnostic Yield of High-resolution Esophageal Manometry With Chicago Classification Version 3.0 in Thai Patients.

BACKGROUND/AIMS: High-resolution manometry with the Chicago classification scheme has been introduced in clinical practice as a gold standard for esophageal motility test. This study aims to evaluate the diagnostic yield of high-resolution manometry in Thai patients. METHODS: All available high-resolution esophageal manometry (HREM) studies performed during the study period were retrospectively reviewed and interpreted according to the Chicago classification version 3.0. The main esophageal symptoms and coexisting factors were correlated with the HREM findings. RESULTS: Of the 201 patients, nearly half (49.8%) were documented to have dysphagia. The second most common condition was refractory reflux symptoms (17.4%). More than 70.0% of dysphagia patients showed abnormal esophageal motility, contrary to globus patients who mostly had normal test findings (65.4%). Dysphagia still was the most often correlated condition with major esophageal motility disorders (88.7%), particularly the elderly patients who have coexisting weight loss. Endoscopic and/or surgical procedures were revealed for the highest rate among patients with dysphagia but no one in the globus group needed this intervention. The sensitivity and specificity of dysphagia for major esophageal motility disorders were 70.0% and 67.0%. A much lower sensitivity and higher specificity were found in other non-dysphagia symptoms, especially nausea/vomiting or belching (3.0% or 89.0%). The highest positive likelihood ratio (2.10) to detect major abnormalities was also observed in dysphagia. CONCLUSION: Esophageal manometry provided the highest yield in dysphagia; it was not a strongly beneficial test in patients presenting with nondysphagia to identify clinically relevant esophageal motor disorders.

No distinction in the gut microbiota between diarrhea predominant-irritable bowel syndrome and healthy subjects: matched case-control study in Thailand.

BACKGROUND: Alteration in the gut microbiota has been proposed in irritable bowel syndrome (IBS) pathogenesis, especially in the diarrheal type (IBS-D). We conducted this study to evaluate the fecal microbiota in Thai IBS-D patients when compared with healthy subjects as well as to evaluate the effects of probiotics on changes in the gut microbiota correlated with symptoms. METHODS: A matched case-control study was conducted on diagnosed IBS-D patients, based on the Rome IV criteria and healthy controls. Stool samples were collected in preservation tubes. Bacterial deoxyribonucleic acid extraction was performed and amplified. Next, 16S ribosomal ribonucleic acid genes sequencing was performed to identify the microbiome in both the groups. IBS-D patients were provided with a probiotic mixture that was rich in Lactobacillus acidophillus and Bifidobacterium bifidum over 8 weeks. Changes in the symptoms, stool characteristics, and fecal microbiota were evaluated and compared with the corresponding baseline values. RESULTS: Twenty IBS-D patients with 20 age and gender-matched controls were included in this study. The baseline characteristics were not significantly different between the groups, including the mode of birth and the history of breastfeeding in infancy. No significant difference was noted in the fecal microbiota between the IBS-D patients and controls. The IBS symptom severity scales (IBS-SSS) were not statistically different after probiotic prescription; although, the bowel movements, the sense of urgency to go to the toilet and passing of mucous stool had obviously decreased. No change was noted in the fecal microbiota after receiving the experimental probiotic, except for an increase in the proportion of B. bifidum. CONCLUSION: Alteration in the gut microbiota composition was probably not the main pathogenic mechanism in the Thai IBS-D patients assessed in this study. However, modifying microbiomes with potentially protective bacteria seems to be a beneficial therapy. Thai Clinical trial registry: TCTR20191211006, Date of registration: 10 Dec 2019.

Management of Ineffective Esophageal Hypomotility.

Esophageal hypomotility in general and especially ineffective esophageal motility according to the Chicago criteria of primary motility disorders of the esophagus, is one of the most frequently diagnosed motility disorders on high resolution manometry and results in a large number of patients visiting gastroenterologists. Most patients with esophageal hypomotility present with gastroesophageal reflux symptoms or dysphagia. The clinical relevance of the motility pattern, however, is not well established but seems to be correlated with disease severity in reflux patients. The correlation with dysphagia is less clear. Prokinetic agents are commonly prescribed as first line pharmacologic intervention to target esophageal smooth muscle contractility and improve esophageal motor functions. However, the beneficial effects of these medications are limited and only confined to some specific drugs. Serotonergic agents, including buspirone, mosapride and prucalopride have been shown to improve parameters of esophageal motility although the effect on symptoms is less clear. Understanding on the complex correlation between esophageal hypomotility and esophageal symptoms as well as the limited evidence of prokinetic agents is necessary for physicians to appropriately manage patients with Ineffective Esophageal Motility (IEM).

Validation of the "Six-and-Twelve" Prognostic Score in Transarterial Chemoembolization-Treated Hepatocellular Carcinoma Patients.

INTRODUCTION: The "six-and-twelve" prognostic score was proposed recently to predict survival rate in patients with unresectable hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE). However, it has not been validated externally. We validated this score and previous prognostic scores in Thai HCC patients treated with TACE. METHODS: We identified all HCC patients who underwent TACE between January 2007 and December 2018 at our hospital. The inclusion criteria were treatment-naive, unresectable HCC BCLC-A and BCLC-B; if cirrhosis was present, Child-Pugh score ≤7; and baseline performance status 0-1. RESULTS: Of 716 HCC patients undergoing TACE, 281 (mean age, 61.1 years; 73.0% men, 92.2% with cirrhosis) were eligible. Approximately half of the patients had hepatitis B virus. Median overall survival was 20.3 (95% confidence interval, 16.4-26.3) months. By stratifying with the "six-and-twelve" score (≤6, >6-12, >12), median (95% confidence interval) overall survival was 35.1 (26.4-53.0), 16.0 (11.6-22.6), and 7.6 (5.4-14.9) months, respectively. Area under the receiver operating characteristic curves (AUROCs) predicting death at 1, 2, and 3 years for the "six-and-twelve" score were 0.714, 0.700, and 0.688, respectively. Compared with the other currently available scores, the AUROC predicting death at 1 year for the "six-and-twelve" score was the most predictive and better than other models except the up-to-seven model. DISCUSSION: Our study confirms the value of the "six-and-twelve" score to predict survival rate of unresectable HCC treated with TACE. However, in our validation cohort, AUROC of the "six-and-twelve" score was slightly lower than that of the original Chinese cohort (0.73).

Clinical Features, Endoscopic Findings, and Predictive Factors for Mortality in Tissue-Invasive Gastrointestinal Cytomegalovirus Disease between Immunocompetent and Immunocompromised Patients.

BACKGROUND AND AIMS: Tissue-invasive gastrointestinal cytomegalovirus (TI-GI CMV) disease is common in immunocompromised patients, but the increasing prevalence in immunocompetent patients has been reported. This study compared the clinical manifestations, endoscopic features, treatment outcomes, and predictors for inhospital mortality of TI-GI CMV between immunocompromised and immunocompetent patients. METHODS: Patients with HIV infection, malignancy, or receiving immunosuppressive agents (chemotherapy, high dose, or long-term corticosteroids) were defined as the immunocompromised group. Demographic and inhospital mortality data were obtained and retrospectively analyzed. RESULTS: A total of 213 patients (89 immunocompetent) with histologically confirmed TI-GI CMV were enrolled. Immunocompetent patients were older (70 vs. 52 years; p < 0.001), had more GI bleeding as a presenting symptom (47.2% vs. 29.0%; p = 0.010), and shorter symptom onset (2 vs. 14 days, p = 0.018). Concomitant extra-GI involvement was only seen in the immunocompromised group (6.5% vs. 0%; p = 0.02). Diffuse GI tract (14.5% vs. 4.5%; p = 0.032) and esophageal involvement (14.5% vs. 5.6%; p = 0.046) were more frequent in the immunocompromised, while small bowel involvement was more frequent in the immunocompetent group (19.1% vs. 8.1%; p = 0.029). An overall inhospital mortality was 27.7%. There was no significant difference in inhospital survival probability between the two groups (Peto-Peto test, p = 0.65). ICU admission (hazard ratio [HR] 7.21; 95% CI 2.55-20.36), sepsis or shock (HR 1.98; 95% CI 1.08-3.66), malnutrition (HR 2.62; 95% CI 1.05-7.01), and receiving chemotherapy (HR 5.2; 95% CI 1.89-14.29) were independent factors for inhospital mortality. Antiviral treatment for more than 14 days was the only protective factor to improve survival (Peto-Peto test, p < 0.001). CONCLUSIONS: Immunocompetent and immunocompromised patients with TI-GI CMV disease had distinct clinical and endoscopic characteristics. There was no significant difference in the inhospital mortality between the two groups. The factors for mortality were ICU admission, sepsis/shock, malnutrition, and receiving chemotherapy. Early diagnosis and initiation of antiviral treatment might improve the survival probability.

Atypical Manifestations of IgG4-Related Disease as Multiple Liver Abscesses with Subcapsular Tracts and Migratory Pulmonary Nodules Mimicking Parasitic Infection.

Immunoglobulin G4-related disease (IgG4-RD) is a fibroinflammatory condition that becomes more recognized as multi-systemic disorders, characterized by three histological hallmarks of IgG4-positive lymphoplasmacytic tissue infiltrate, storiform fibrosis, and obliterative phlebitis. This disease has been reported in virtually every organ system, but the hepatic manifestations remain poorly defined. Moreover, IgG4-RD can mimic many malignancies, inflammatory disorders and infectious diseases. This report revealed IgG4-related liver disease with atypical presentation presenting with multiple liver abscesses and linear tracts mimicking parasitic infection.

The Impact of COVID-19 on Gastrointestinal Motility Testing in Asia and Europe.

BACKGROUND: The new coronavirus disease (COVID-19) has high infection and mortality rates, and has become a pandemic. The infection and mortality rates are lower in Asian countries than in European countries. This study aimed to conduct a survey on the effects of COVID-19 on the capacity to perform gastrointestinal motility tests in Asian countries compared with European countries. METHODS: We used the questionnaire previously established by our team for researchers in European countries. The correlation between the decreased rate of gastrointestinal motility and function tests, and the infection/mortality rates of COVID-19 and stringency of a government's interventions in each country was analysed and protective measures were assessed. RESULTS: In total, 58 gastroenterologists/motility experts in Asian countries responded to this survey. The infection/mortality rates of COVID-19 and Stringency Index had a significant impact on the testing capacity of oesophageal manometry and catheter-based pH monitoring. In European countries, most facilities used filtering facepiece 2/3 (FFP2/3) masks during oesophageal motility studies. Meanwhile, in Asian countries, most facilities used surgical masks. CONCLUSION: The total infection and mortality rates of COVID-19 can affect the rate of gastrointestinal motility testing and the type of protective equipment that must be used.

A survey on the impact of the COVID-19 pandemic on motility and functional investigations in Europe and considerations for recommencing activities in the early recovery phase.

BACKGROUND: The COVID-19 pandemic, declared by WHO on March 13, 2020, had a major global impact on the healthcare system and services. In the acute phase, the presence of the SARS-CoV-2 virus in the aerodigestive tract limited activities in the gastroenterology clinic and procedures to emergencies only. Motility and function testing was interrupted and as we enter the recovery phase, restarting these procedures requires a safety-focused approach with adequate infection prevention for patients and healthcare professionals. METHODS: We summarized knowledge on the presence of the SARS-CoV-2 virus in the aerodigestive tract and the risk of spread with motility and functional testing. We surveyed 39 European centers documenting how the pandemic affected activities and which measures they are considering for restarting these measurements. We propose recommendations based on current knowledge as applied in our center. RESULTS: Positioning of catheters for gastrointestinal motility tests carries a concern for aerosol-borne infection of healthcare workers. The risk is low with breath tests. The surveyed centers stopped almost all motility and function tests from the second half of March. The speed of restarting and the safety measures taken varied highly. CONCLUSIONS AND INFERENCES: Based on these findings, we provided recommendations and practical relevant information for motility and function test procedures in the COVID-19 pandemic era, to guarantee a high-quality patient care with adequate infection prevention.
