Abstract
Regarding neurophysiological and developmental findings, anxiety and depression are usual comorbidities of gastritis patients. However, research related to anxiety and depression among chronic gastritis patients was conducted on the disease level while ignoring symptoms. Hence, we rendered the network approach to reveal the symptoms of anxiety and depression among chronic gastritis patients. Three hundred and sixty-nine chronic gastritis patients (female = 139, Mage = 55.87 years) were asked to complete the Self-Rating Anxiety Scale and Self-Rating Depression Scale. Three symptom networks and one directed acyclic graph (DAG) network were formed. First, in the anxiety network of chronic gastritis patients, dizziness was the most influential symptom. In the depression network of chronic gastritis patients, depressed affect and psychomotor retardation were the influential symptoms. Second, panic, easy fatiguability, weakness, palpitation, depressed affect, tachycardia, fatigue, and psychomotor agitation bridged the anxiety-depression network of chronic gastritis patients. Third, DAG networks showed that anxiousness and hopelessness could trigger other symptoms in the anxiety-depression networks of chronic gastritis patients. The current study provided insightful information on patients with chronic gastritis by examining the structures of symptoms.

Probiotic Supplementation With Saccharomyces boulardii and Enterococcus faecium Improves Gastric Pain and Bloating in Airline Pilots With Chronic Non-atrophic Gastritis: An Open-Label Study. Cureus 2024; 16:e52502. [PMID: 38371107 PMCID: PMC10870090 DOI: 10.7759/cureus.52502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Accepted: 01/17/2024] [Indexed: 02/20/2024] Open
Abstract
Background Commercial airline pilots (APs) are prone to upper gastrointestinal symptoms, such as epigastric pain and bloating. These issues are often linked to occupational risk factors like irregular diet, sleep disruption, and circadian rhythm disturbance. The use of probiotics to enhance intestinal health is well established, but their efficacy in treating upper gastrointestinal diseases is still debated. This is primarily due to the stomach's small resident microbiota and its low pH, which is inhospitable to most microbes. However, emerging research suggests that specific probiotic strains, such as Enterococcus faecium, can withstand acidic environments. Moreover, certain yeast species, including Saccharomyces boulardii, can survive at a low pH. Consequently, we conducted a preliminary, three-arm, randomized, open-label, dose-finding, four-week study to compare the effects of watchful waiting (WW) with the administration of an oral probiotic supplement containing S. boulardii and E. faecium in APs diagnosed with Helicobacter pylori-negative chronic non-atrophic gastritis (CNG). Methods The study included 39 APs with CNG who were randomized into three groups with a 1:1:1 ratio. The low-dose group (n = 13) received one capsule of the probiotic supplement twice daily, before meals, for four weeks. The high-dose group (n = 13) was administered two capsules of the supplement on the same schedule. The third group (n = 13) underwent WW and served as the control arm. Blinding was maintained for the examining physicians and laboratory staff, but not for the patients. All participants self-rated their experiences of gastric pain and bloating at the beginning and conclusion of the four-week treatment period. Additionally, serum levels of pepsinogen I (PGI) and pepsinogen II (PGII) were measured at these time points. Results Supplementation with probiotics significantly outperformed WW in reducing subjective gastric pain and bloating. This effect was consistent across both tested dosages, with no significant differences observed. However, only high-dose probiotics led to a statistically significant decrease in PGII levels and an increase in the PGI/PGII ratio after the four-week study period, a result not observed with low-dose probiotics. Conclusions Oral administration of S. boulardii and E. faecium demonstrated potential efficacy in reducing gastric pain and bloating symptoms in APs with CNG, as evidenced by statistically significant symptom improvement compared to the control group that did not receive the probiotic supplementation. Notably, high-dose probiotics resulted in a significant increase in the PGI/PGII ratio, indicating potential long-term cytoprotective effects on the gastric mucosa.

Abstract
OBJECTIVES Societies' guidelines suggest routine tissue sampling in all children undergoing esophagogastroduodenoscopy and ileocolonoscopy, even in the absence of visible endoscopy abnormalities. We aimed to determine the agreement between endoscopic and histopathological findings in pediatric endoscopy and to assess the yield of routine biopsies from all sites. METHODS Since January 2019, our endoscopy institute protocol has included routine biopsies sampling from the esophagus, stomach, duodenum, ileum, and colon in all diagnostic procedures. Agreement between tests was done using the kappa coefficient ( κ ). The study included all endoscopies performed during 2019. RESULTS In total, 541 diagnostic endoscopies were done during the study period with 434 (80%) esophagogastroduodenoscopy and 107 (20%) were ileocolonoscopy. Compared to histology, endoscopic findings performance were: esophagus-sensitivity 33%, specificity 98%; stomach-sensitivity 60%, specificity 89%; duodenum-sensitivity 50%, specificity 97%; duodenal bulb-sensitivity 47%, specificity 89%; terminal ileum-sensitivity 82%, specificity 100%; colon-sensitivity 84%, specificity 96%. Assessment of concordance between endoscopic and histopathologic findings reveals an overall low level of agreement in esophagogastroduodenoscopy ( κ of 0.39, 0.51, 0.53, and 0.24 for the esophagus, stomach, duodenal second part, and bulb, respectively), and good agreement in ileocolonoscopy ( κ of 0.88 and 0.81 for the ileum and colon, respectively). CONCLUSIONS Endoscopy findings are highly specific for histologic pathology, whereas the absence of findings correlates poorly with histologic findings. Ileocolonoscopy shows better agreement than esophagogastroduodenoscopy. Our data support routine tissue sampling in pediatric endoscopy.

Abstract
AIMS To examine the clinicopathological characteristics of granulomatous gastritis (GG) among different etiologies, particularly Crohn disease (CD), and determine the contribution of H. pylori and the clinical significance of isolated GG. METHODS/RESULTS We identified 269 GG cases overall (0.19% prevalence): 220 had an underlying granulomatous disease (CD, sarcoidosis, tuberculosis) and only 8 of these (3.6%) had H. pylori, fewer than the 10.3% rate among non-GG biopsies (p<.001). Conversely, among 49 GG cases without known cause (foreign body, undetermined, idiopathic), 13 (26.5%) had H. pylori, more than background (p=.001). Most patients (n=185/68.8%) had CD and these were more likely male (p<.001), younger (p<.001), white (p<.001), and had single (p=.010), smaller (p=.005), antral (p=.027) granulomas, amid inflammation (p=.005), compared to non-CD GG cases; younger age was independently associated with CD (p=.003; OR=1.13, 95% CI: 1.04-1.22). Among CD patients, younger age (p=.003; OR=1.04, 95% CI: 1.01-1.07) and upper gastrointestinal (GI) symptoms (p=.017; OR=2.53, 95% CI: 1.18-5.43) were associated with new (vs. established) diagnosis, whereas multiple gastric granulomas (p=.003; OR=4.67, 95% CI: 1.67-13.04) and lack of upper GI symptoms (p<.001; OR=6.75, 95% CI: 2.94-15.49) were associated with lower GI granulomas. Of 86 isolated GG cases (i.e., no prior diagnosis or lower GI granulomas), 51 (59.3%) were eventually diagnosed with CD, and this was independently associated with younger age (p=.014; OR=1.11, 95% CI: 1.02-1.21) and upper GI symptoms (p=.033; OR=19.27, 95% CI: 1.27-293.31). The positive predictive value of finding isolated GG towards a CD diagnosis in patients <30 years-old was 91%, increasing in males (93%), with single (94%), antral (97%) granulomas, or upper GI symptoms (94%). CONCLUSIONS GG does not correlate with H. pylori in patients with granulomatous disease, but may be associated with the organism when such diagnosis is lacking. In CD patients with GG, younger age and upper GI symptoms are associated with a new CD diagnosis, whereas multiple gastric granulomas and lack of upper GI symptoms correlate with lower GI granulomas. GG, including in isolated cases with no prior clinical history or granuloma, likely signifies CD, particularly in younger, male patients, or those with single, antral granulomas, or upper GI symptoms.

Abstract
Objectives: There is a lack of evidence-based consensus for the utility of gastrointestinal endoscopy (GIE) in an array of frequently occurring symptoms in children. We aimed to assess the diagnostic yield of endoscopy in an effort to aid clinical decision making. Methods: Retrospective analysis included patients ≤18 years who underwent GIE during one calendar year at Shaare Zedek Medical Center. We excluded children referred for predefined obvious indications for GIE, planned follow-up procedures, and therapeutic endoscopy. Clinician-assigned indication for endoscopy as well as endoscopic and histologic findings were recorded. Diagnostic yield of GIE was determined according to referral indication. Results: There were 794 endoscopies performed of which 329 were included in the analysis (mean age 9.3 ± 5.0 years, 51% female). No significant complications of GIE were recorded. Six major referral indications were identified among which abdominal pain was the most frequent 88/329 (26%) of whom 32/88 (36%) had a significant diagnostic finding. Among the other major indications, diagnostic findings were found in 36/85 (43%) children with primary indication of chronic diarrhea, 14/33 (42%) failure to thrive, 15/32 (46%) short stature, 30/56 (54%) iron deficiency, and 20/48 (42%) weight loss. Conclusions: Pediatric GIE is a safe procedure with diverse clinical indications. The diagnostic yield of endoscopy is variable, depending on the referral indication. These data can assist formulating judicious referral practices.

Abstract
Although the features of lower gastrointestinal tract inflammation associated with ulcerative colitis and Crohn disease are generally familiar to pathologists, there is less awareness of and familiarity with the manifestations of inflammatory bowel disease in the esophagus, stomach, and duodenum. Nonetheless, their diagnosis has therapeutic and possibly prognostic implications, potentially foretelling severe complications. The recognition that ulcerative colitis can affect gastrointestinal organs proximal to the large intestine and terminal ileum represents a revision of concepts ingrained among generations of physicians. This article reviews the pathologic features and clinical significance of esophagitis, gastritis, and duodenitis associated with inflammatory bowel disease.

Abstract
BACKGROUND Chronic gastritis (CG), as the highest incidence of gastrointestinal diseases, has been gradually increasing around globally. With the obvious disadvantages of standard treatment, more and more people ask the traditional Chinese medicine for help in the treatment of CG. As a traditional Chinese medicine compound, Zuojin Pill (ZJP) has a long history of clinical application in the treatment of digestive system diseases. Whereas, neither systematic nor meta-analysis of randomized controlled trials explain the efficacy and safety of ZJP in treating CG. Thus, we provide a protocol to evaluate the efficacy and safety of ZJP for CG. METHODS From the beginning to December 2019, the following electronic databases will be searched for studies in English or Chinese: the Cochrane Library, Embase, PubMed, Web of Science, the Chinese National Knowledge Infrastructure, the Chinese Biomedical Literature Database, the Chinese Scientific Journal Database, and the Wanfang Database. Clinical efficiency, helicobacter pylori infection clearance rate, quality of life and symptom scores will be measured as primary outcomes. Meta-analysis will be performed using the Stata 15. OUTCOMES This study will provide the current evidence of CG treated with ZJP from the several aspects including clinical efficiency, helicobacter pylori infection clearance rate, quality of life, symptom scores, the 1-year recurrent rate, efficacy under endoscopy and number of reported adverse events associated with the use of ZJP. CONCLUSION The outcomes of this review will be served as a proof to evaluate if ZJP is effective in the treatment of CG. PROSPERO REGISTRATION NUMBER PROSPERO CRD42020155036.

Abstract
The human genome is constantly exposed to exogenous and endogenous DNA damaging factors that frequently cause DNA damages. Unless repaired, damaged DNA can result in deleterious mutations capable of causing malignant transformation. Accordingly, cells have developed an advanced and effective surveillance system, the DNA damage response (DDR) pathway, which maintains genetic integrity. In addition to well-defined outcomes, such as cell cycle arrest, apoptosis, and senescence, another consequence of DDR activation is the induction of natural killer group 2 member D ligands (NKG2D-Ls) on the surface of stressed cells. Consequently, NKG2D-Ls-expressing cells are recognized and eliminated by NKG2D receptor-expressing immune cells, including NK cells, and various subsets of T-cells. Recent pieces of evidence indicate that commensal microbial imbalance (known as dysbiosis) can trigger DDR activation in host cells, which may result in sustained inflammatory responses. Therefore, dysbiosis can be seen as an important source of DNA damage agents that may be partially responsible for the overexpression of NKG2D-Ls on intestinal epithelial cells that is frequently observed in patients with inflammatory bowel disease and other disorders associated with altered human microbiota, including the development of colorectal cancer. In this article, we discuss recent evidence that appears to link an altered human microbiota with autoimmunity and carcinogenesis via the activation of DDR signals and the induction of NKG2D-Ls in stressed cells.

Abstract
Gastric biopsies are routinely obtained from patients with symptoms related to the gastrointestinal tract and, as a result, a variety of histologic changes are observed in patients with or without endoscopic evidence of mucosal injury. Although Helicobacter pylori-related gastritis is still common, several other patterns of mucosal injury are increasingly encountered. These patterns of injury are classified based on the nature and distribution of inflammation, location of epithelial cell injury, presence of crystal or pigment deposition, and/or other unique features. This article discusses each of these patterns and provides a differential diagnosis for each.

Abstract
The links between microorganisms/viruses and autoimmunity are complex and multidirectional. A huge number of studies demonstrated the triggering impact of microbes and viruses as the major environmental factors on the autoimmune and inflammatory diseases. However, growing evidences suggest that infectious agents can also play a protective role or even abrogate these processes. This protective crosstalk between microbes/viruses and us might represent a mutual beneficial equilibrium relationship between two cohabiting ecosystems. The protective pathways might involve post-translational modification of proteins, decreased intestinal permeability, Th1 to Th2 immune shift, induction of apoptosis, auto-aggressive cells relocation from the target organ, immunosuppressive extracellular vesicles and down regulation of auto-reactive cells by the microbial derived proteins. Our analysis demonstrates that the interaction of the microorganisms/viruses and celiac disease (CD) is always a set of multidirectional processes. A deeper inquiry into the CD interplay with Herpes viruses and Helicobacter pylori demonstrates that the role of these infections, suggested to be potential CD protectors, is not as controversial as for the other infectious agents. The outcome of these interactions might be due to a balance between these multidirectional processes.

Abstract
BACKGROUND Quantitative analysis of the number, normal and pathologic ratios between lymphocytes and epithelial cells (ECs), and the significance of intraepithelial lymphocytes (IELs) in normal prostatic epithelium, benign prostatic hyperplasia (BPH), and high grade prostatic intraepithelial neoplasia (PIN) in relation to NIH category IV prostatitis (histologic prostatitis: HP) was studied in autopsy prostate. METHODS IELs were analysed in 59 autopsy prostates, which was routinely embedded in paraffin and immunohistochemically stained for CD3. An average of 300-500 ECs were counted per case. The number of IELs was calculated as the mean/100 ECs. Category IV prostatitis was evaluated using NIH consensus grading system in terms of anatomical localization and grade. RESULTS In healthy individuals the mean number of IELs/100 ECs was 0.61 ± 0.34% or ≤1 lymphocyte/100 ECs, which is considered as the normal basal level of prostate IELs. In category IV prostatitis, the mean number of IELs/100 ECs was 8.53 ± 3.25% or 5-11 lymphocytes/100 ECs. The number of IELs in both around and inside inflammation areas correlated to the grade and location of HP (P < 0.0001 and P < 0.0003), the presence of acute glandular inflammation (P < 0.0001), the scattered stromal lymphocytes (P = 0.029), and BPH and PIN associated prostatic inflammation (P < 0.0001). CONCLUSION The study presents the first attempt to examine and score the basic quantitative values of prostatic IELs in normal prostate and in relation to category IV prostatitis. The detected normal upper limit of CD3+ IELs is 1 lymphocyte/100 ECs in the normal prostate epithelium. This is considered as an organ specific characteristic of the prostate-associated lymphoid tissue (PALT). Values >5 IELs/100 ECs indicate the presence of category IV prostatitis. The severity of inflammation correlates to the number of IELs. There is an intimate link between the quantity of the IELs, the degree of the severity and the localization of category IV prostatitis. HP is a chronic and dynamic inflammatory process affecting the whole prostate gland. The increased number of IELs suggests the immune or autoimmune character of category IV prostatitis, BPH and inflammatory preneoplastic (PIN) lesions in the prostatic tumor environment.
