Abstract
Gallbladder cancer (GBC) is the most common malignant tumor of the biliary system with the worst prognosis. Even after radical surgery, the majority of patients with GBC have difficulty achieving a clinical cure. The risk of tumor recurrence remains more than 65%, and the overall 5-year survival rate is less than 5%. The gut microbiota refers to a variety of microorganisms living in the human intestine, including bacteria, viruses and fungi, which profoundly affect the host state of general health, disease and even cancer. Over the past few decades, substantial evidence has supported that gut microbiota plays a critical role in promoting the progression of GBC. In this review, we summarize the functions, molecular mechanisms and recent advances of the intestinal microbiota in GBC. We focus on the driving role of bacteria in pivotal pathways, such as virulence factors, metabolites derived from intestinal bacteria, chronic inflammatory responses and ecological niche remodeling. Additionally, we emphasize the high level of correlation between viruses and fungi, especially EBV and Candida spp., with GBC. In general, this review not only provides a solid theoretical basis for the close relationship between gut microbiota and GBC but also highlights more potential research directions for further research in the future.

Mitsui I, Uchida K. Canine Gallbladder Erosion/Ulcer and Hemocholecyst: Clinicopathological Characteristics of 14 Cases. Animals (Basel) 2023; 13:3335. [PMID: 37958090 PMCID: PMC10649012 DOI: 10.3390/ani13213335] [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: 07/21/2023] [Revised: 10/08/2023] [Accepted: 10/24/2023] [Indexed: 11/15/2023] Open
Abstract
(1) Background: Gallbladder mucosal erosion and/or ulceration are illnesses associated with unexpected gallbladder intra-cystic bleeding (hemocholecyst), an under-reported problem in dogs. (2) Methods: Clinicopathological characteristics of 14 dogs with gallbladder erosion/ulcer were investigated in this single-center retrospective study using clinical data and archived gallbladder tissues of client-owned dogs. (3) Results: Canine gallbladder erosion/ulcer tends to occur in older, neutered dogs of various breeds. Vomiting, lethargy, and anorexia are common. Concurrent gallbladder rupture occurred in 5/14 cases (35.7%), while rupture was absent in 6/14 cases (42.8%) and undetermined in 3/14 (21.4%) cases. Histologically, the gallbladder wall was markedly thickened due to mucosal hyperplasia, inflammatory infiltrates, fibrosis, edema, hemorrhage, and smooth muscle hyperplasia/hypertrophy. Twelve out of fourteen cases (85.7%) had concurrent cholecystitis of varying severity. Bacteria were detected by Giemsa or Warthin-Starry stain in 8/14 (57.1%) cases. Bacterial rods immunoreactive to the anti-Helicobacter antibody were present in one case. Mucosal epithelial cells of the gallbladder erosion/ulcer cohort were immunopositive for the cyclooxygenases COX-1 or COX-2 in only 5/14 (35.7%) cases. In contrast, COX-1 and COX-2 were more frequently expressed in a reference pool of cases of gallbladder mucocele (n = 5) and chronic cholecystitis (n = 5). COX-1 was expressed in 9/10 cases (90.0%) of gallbladder mucocele and chronic cholecystitis and in 10/10 cases (100%) for COX-2. (4) Conclusions: Canine gallbladder erosion/ulcer is an under-reported condition which requires active clinical intervention. Based on the clinicopathological information reported in this study in addition to the COX-1 and COX-2 IHC results, we suggest that canine gallbladder erosion/ulcer may be related to decreased cytoprotection physiologically provided by arachidonic acid, but which is decreased or absent due to reduced COX expression because of yet undetermined etiologies.

Abstract
Helicobacter pylori is a gram-negative pathogen commonly associated with peptic ulcer disease and gastric cancer. H. pylori infection has also been reported in cholelithiasis, cholecystitis, gallbladder polyps, and biliary tract cancers. However, the association between H. pylori and gallbladder and biliary tract pathologies remains unclear due to the paucity of literature. In response to the current literature gap, we aim to review and provide an updated summary of the association between H. pylori with gallbladder and biliary tract diseases and its impact on their clinical management. Relevant peer-reviewed studies were retrieved from Medline, PubMed, Embase, and Cochrane databases. We found that H. pylori infection was associated with cholelithiasis, chronic cholecystitis, biliary tract cancer, primary sclerosing cholangitis, and primary biliary cholangitis but not with gallbladder polyps. While causal links have been reported, prospective longitudinal studies are required to conclude the association between H. pylori and gallbladder pathologies. Clinicians should be aware of the implications that H. pylori infection has on the management of these diseases.

Quantitative Analysis of Mucin Expression Using Combined Alcian Blue-Periodic Acid Schiff (AB-PAS) Stain and Combined High Iron Diamine-Alcian Blue (HID-AB) Stain and the Correlation With Histomorphological Score in Chronic Calculous Cholecystitis. Cureus 2022; 14:e32033.

Abstract
Introduction Chronic calculous cholecystitis is the most common and important contributing factor for cholecystectomy across the country, with a prevalence of 2-29%. Cholesterol supersaturated bile plays a major role in stone formation. It is very essential to identify the pathogenesis of stone formation in order to prevent its formation. This study is aimed to evaluate histomorphological features of chronic calculous cholecystitis and to quantitatively evaluate alteration in mucin expression using the combined Alcian blue-periodic acid Schiff (AB-PAS) stain and the combined high iron diamine Alcian blue (HID-AB) stain, to correlate with each other and also with biochemical features of gall stones. Methods A cross-sectional study of 64 chronic calculous cholecystitis were taken for histomorphological assessment and grading using Hematoxylin and Eosin (H&E) stain and Masson's trichrome stains. Expression of the type of mucins was analyzed using histochemical stains by a standardized scoring system. Results A significant positive correlation was observed between an increase in grades of inflammation and fibrosis with an increase in the quantity of sialomucin and neutral mucin in the deep layers of epithelium, and a significant negative correlation was observed between an increase in grades with a decrease in acidic mucin and sulfomucin of both superficial and deep epithelium except sulfomucin in fibrosis. No significant correlation was obtained with muscle thickness, adipose tissue deposition, and epithelial hyperplasia. A higher frequency of mixed-type stones was associated with severe inflammation. Conclusion Inflammation and fibrosis were strongly correlated with quantitative alteration and reversal of mucin composition in chronic cholecystitis; hence we conclude that these features play a significant role in the pathogenesis of stone formation. Using Combined AB(2.5pH)-PAS stain and Combined HID-AB(2.5 pH) stain to detect mucin hypersecretion and composition of altered mucin is relatively accurate and cost-effective rather than performing costly immunohistochemical (IHC) markers.

Value of Multislice Spiral CT in Differential Diagnosis of Thick-Wall Gallbladder Carcinoma and Chronic Cholecystitis. CONTRAST MEDIA & MOLECULAR IMAGING 2022; 2022:5459779. [PMID: 35601565 PMCID: PMC9106503 DOI: 10.1155/2022/5459779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 04/02/2022] [Accepted: 04/08/2022] [Indexed: 11/17/2022]
Abstract
To summarize the value of multislice spiral CT (MSCT) in the differential diagnosis of thick-wall gallbladder carcinoma (TWGC) and chronic cholecystitis (CC), the clinical data of 36 patients with TWGC and 60 patients with chronic cholecystitis who were treated in our hospital from January 2017 to May 2021 were retrospectively analyzed, and the CT image features and diagnostic accuracy of the patients were summarized. Compared with the CC group, the proportions of disruption of gallbladder mucosa line, blurred gallbladder outline, high obstruction of biliary tract, lymphomegaly, adjacent invasion, peritoneal effusion, wall nodules, and the gallbladder wall thickness in the TWGC group were higher, with statistical significance (P < 0.05). Thirty-four patients with TWGC and 62 patients with chronic cholecystitis were diagnosed by MSCT. The sensitivity and specificity of MSCT in diagnosing TWGC were 86.11% and 95.00%, respectively. The positive likelihood ratio was 17.222 and the negative likelihood ratio was 0.1462. The positive prediction rate was 91.18%, the negative prediction rate was 91.94%, and the correct rate was 91.67%. MSCT can show the characteristic difference between TWGC and chronic cholecystitis, which can be used for differential diagnosis.

Abstract
Co-infection with the cagA strain of Helicobacter pylori exacerbates the pathology of human liver fluke Opisthorchis viverrini (OV) infection leading to cholangiocarcinoma. However, underlying mechanisms remain unclear. We report a significant increase in cagA-positive and cagA-negative H. pylori in the stomach, blood, bile, and in the OV worms of co-infected Syrian golden hamsters at one hour, three hours, and one month, post-infection, compared to hamsters infected with either OV or H. pylori alone. Except in the worms, H. pylori numbers declined at three months post-infection, particularly in the bile fluid of co-infected animals. Both strains of H. pylori were immunohistochemically detected in the tegument of the worm, as well as in the bile duct epithelium when co-infected with O. viverrine, but not in H. pylori infection alone. Interestingly, only the cagA-positive strain was detected in the gut of the worm. Co-infection between cagA-positive H. pylori and O. viverrini resulted in a more severe biliary pathology and decreased E-cadherin expression in vivo and in vitro than those of the cagA-negative strain. These data suggest that O. viverrini acts as a carrier of cagA-positive H. pylori and co-migrates to the bile ducts, whereas O. viverrini facilitates H. pylori colonization and enhances the biliary pathogenesis and carcinogenesis.

Abstract
BACKGROUND Helicobacter pylori (HP) has been detected in the hepatobiliary tract of cholangiocarcinoma (CCA) patients in regions both endemic and non-endemic for Opisthorchis viverrini (OV) infection. However, whether H. pylori infection promotes CCA development remains unknown. We investigated CCA development in hamsters induced by a combination of infection with H. pylori and administration of N-nitrosodimethylamine (NDMA) and compared findings with those in an OV plus NDMA group. MATERIALS AND METHODS Eighty-five hamsters were divided into four groups: (1) normal, (2) administered NDMA, (3) infected with cagA+ H. pylori and administered NDMA (HN group), and (4) infected with OV and administered NDMA (ON group). Animals were euthanized at 3 and 6 months post-infection. Histopathological changes of liver and the expression of markers associated with carcinogenesis were studied. RESULTS At 3 months post-infection (p.i.), cholangitis and lymphoid follicles without tumor appearance were noted in the HN group, whereas extensive fibrosis was seen in members of the ON group, 10% of which had developed tumors. At 6 months p.i., 10% of hamsters administered NDMA alone had developed CCA, whereas in the HN and ON groups, 20% and 60% of hamsters, respectively, had developed CCA. Cytokeratin-19 (CK19) expression was observed in the CCA tissues of both the HN and the ON groups, confirming the bile duct origin of the CCA cells. CCA development in the HN group might be inflammation-mediated, as suggested by overexpression of HMGB1, PCNA, IL-8, and 8-OxodG in CCA tissues. CONCLUSION cagA+ H. pylori infection and carcinogen intake can induce CCA development with slow progression.

The Relationship between Helicobacter pylori Infection of the Gallbladder and Chronic Cholecystitis and Cholelithiasis: A Systematic Review and Meta-Analysis. Can J Gastroenterol Hepatol 2021; 2021:8886085. [PMID: 33505946 PMCID: PMC7806380 DOI: 10.1155/2021/8886085] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2020] [Revised: 11/04/2020] [Accepted: 11/28/2020] [Indexed: 02/07/2023] Open
Abstract
Helicobacter pylori (H. pylori) is proved to be the main pathogenic agent of various diseases, including chronic gastritis, gastric ulcer, duodenal ulcer, and gastric cancer. In addition, chronic cholecystitis and cholelithiasis are common worldwide, which are supposed to increase the total mortality of patients. Epidemiologic evidence on the relationship between H. pylori infection of the gallbladder and chronic cholecystitis/cholelithiasis still remains unclear. We conducted a systematic review and meta-analysis of overall studies to investigate the relationship between H. pylori infection of the gallbladder and chronic cholecystitis/cholelithiasis. Two researchers searched PubMed, Embase, and Cochrane Library databases to obtain all related and eligible studies published before July 2020. The pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated by the random-effects model. Subgroup analysis, heterogeneity, publication bias, and sensitivity analysis were also conducted. Twenty studies were included in the meta-analysis, involving 1735 participants and 1197 patients with chronic cholecystitis/cholelithiasis. Helicobacter species infection of the gallbladder was positively correlated with increased risk of chronic cholecystitis and cholelithiasis, especially H. pylori (OR = 3.05; 95% CI, 1.81-5.14; I 2 = 23.5%). Besides, country-based subgroup analysis also showed a positive correlation between the gallbladder H. pylori positivity and chronic cholecystitis/cholelithiasis risk. For Asian and non-Asian country studies, the ORs were 4.30 (95% CI, 1.76-10.50; I 2 = 37.4%) and 2.13 (95% CI, 1.23-3.70; I 2 = 0.0%), respectively. The association was more obvious using the bile sample and urease gene primer. In conclusion, this meta-analysis provided evidence that there is a positive correlation between H. pylori infection in the gallbladder and increased risk of chronic cholecystitis and cholelithiasis.

Abstract
CONTEXT. Follicular cholecystitis (FC) is a poorly characterized entity. OBJECTIVE. To determine its frequency/clinicopathologic associations. DESIGN. A total of 2550 cholecystectomy specimens were examined. Two hundred three of these were consecutive routine cholecystectomies submitted entirely for microscopic examination to determine the relative frequency of incidental pathologies in gallbladders (GBs). The remainder had representative sampling. Underlying conditions were nonobstructive pathologies (1270 nonspecific cholecystitis), obstructive (62 distal biliary tract tumors, 35 primary sclerosing cholangitis, and 31 autoimmune pancreatitis), and neoplastic (n = 949). FC was defined as 3 distinct lymphoid follicles (LFs)/centimeter. RESULTS. In the GBs totally submitted for microscopic examination, the true frequency of FC was found to be 2.5% (5/203), and in the representatively sampled group, it was 1.9%, with similar frequencies in nonobstructive, obstructive, and neoplastic cases (2.3%, 3.1%, and 1.3%, respectively, P = .77). When the 39 FC in nonneoplastic GBs contrasted with ordinary chronic cholecystitis, they were associated with older age (68 vs 49 years, P < .0001), similar gallstone frequency (68 vs 81%), female/male ratio (2.7 vs 2.6), and wall thickness (4 mm for both). None had lymphoma/parasites/Salmonella infection. Of 17 cases who had undergone gastric biopsy, 5 had chronic gastritis (2 with Helicobacter pylori). Microscopically, the LFs were the main inflammatory process often with minimal intervening inflammation. IgG4-positive plasma cell density was low (<10/high-power field) in 21/24(87.5%) cases. CONCLUSIONS. Follicular cholecystitis is seen in 2% of cholecystectomies, typically in significantly older patients, suggesting a deranged immune response. A third of the patients reveal biopsy-proven gastritis. FC does not seem to be associated with autoimmunity, lymphoma, or obstructive pathologies.

Abstract
It is of interest to assess the clinical and pathological aspects of Gallbladder and biliary tract carcinomas confirmed by histological data.
It is also of further interest to evaluate the link between Helicobacter pylori and biliary tract cancers. Eighty-nine (89) cases (mean age 60±12 years)
of Gallbladder and biliary tract cancer confirmed by histological data were enrolled for the study at the Department of Pathology in Mohammed VI University
Hospital, in Morocco. The data such as age, sex, clinical and histo pathological features were collected. Bile duct specimens were investigated for H. pylori
using Giemsa and immuno histo chemistry staining. Results show that bile duct stones were found in 53.9% of cases. It is known using histological data that
adeno carcinoma is common accounting for 70 % of all bile duct tumors. Moreover, Helicobacter pylori was detected in 54% of cases linking with the presence
of bile duct stones characterized by the histological subtype, the macroscopic classification and lymph node's presence (p<0.001). Thus, data collected suggest
the potential association of Helicobacter pylori with gallbladder cancer possibly through the formation of bile duct stones.

Abstract
Objective Helicobacter pylori commonly occurs in the stomach, but localizations outside the stomach and related diseases have also been investigated. However, the relationship between H. pylori and gallstones remains controversial. We aimed to investigate the relationships between H. pylori in the stomach and the gallbladder and gallstones. Methods This prospective case-control study included patients who underwent cholecystectomy because of gallstones, pancreatic head cancer, or hepatic resection. The patients were separated into two groups according to the detection of H. pylori in gallbladder samples using Giemsa staining. Stomach H. pylori status was based on previous gastroscopy. Results The study enrolled 60 patients, comprising 27 patients with gallstones and 33 without. There was no significant difference in the incidence of gallstones between patients with or without H. pylori in the stomach or gallbladder. Furthermore, the presence of H. pylori in the stomach was measured in 14 patients and was significantly correlated with H. pylori in the gallbladder. Conclusion The current study showed no relationship between the occurrence of gallstones and the presence of H. pylori in either the gallbladder or the stomach. In contrast to previous reports, this suggests that H. pylori does not play a role in the development of gallstones.

Abstract
Helicobacter pylori infection of the human stomach is associated with chronic gastritis, peptic ulcer disease or gastric carcinoma, and thus a high burden for the public health systems worldwide. Fortunately, only a small subfraction of up to 15-20% of infected individuals will develop serious complications. Unfortunately, it is not always known upfront, who will be affected by serious diesease outcome. For risk stratifications, it is therefore necessary to establish a common terminology and grading system, that can be applied worldwide to compare population data. The updated Sydney System for classification of gastritis with its semi-quantitative analogue scale is the system, that is currently used worldwide. Additionally, pathologists should always try to classify the etiology of the inflammatory infiltrates in the stomach to instruct the clinicians for choosing a proper treatment regime. Risk factors such as intestinal metaplasia, atrophy and scoring systems to classify these risk factors into a clinical context such as OLGA and OLGIM are discussed. Also, special forms of gastritis like lymphocytic gastritis, autoimmune gastritis and peptic ulcer disease are explained and discussed e.g. how to diagnose and how to treat. Extra-gastric sequelae of H. pylori infections inside and outside the stomach are shown in this chapter as well. Important host and bacterial risk factors such as pathogenicity islands are dicussed to draw a complete landscape around a H. pylori infection, that still can be diagnosed in patients. However, it needs to be noted that some countries have almost no H. pylori infection anymore, while others have still a very high frequency of infections with or without serious complications. The understanding and application of risk assessements may help to save money and quality of life. Extra-gastric H. pylori infections are rarely reported in the literature until today. The pathogenitiy is still under debate, but especially in the bile ducts and gallbladder, several pathological conditions may be also based on H. pylori infection, and will be also discussed.

Unusual Manifestation of Live Staphylococcus saprophyticus, Corynebacterium urinapleomorphum, and Helicobacter pylori in the Gallbladder with Cholecystitis. Int J Mol Sci 2018; 19:ijms19071826.

Abstract
Culture-independent studies have identified DNA of bacterial pathogens in the gallbladder under pathological conditions, yet reports on the isolation of corresponding live bacteria are rare. Thus, it is unclear which pathogens, or pathogen communities, can colonize the gallbladder and cause disease. Using light microscopy, scanning electron microscopy, culture techniques, phylogenetic analysis, urease assays and Western blotting, we investigated the presence of live bacterial communities in the gallbladder of a cholecystitis patient after cholecystectomy. 16S rRNA gene sequencing of isolated bacterial colonies revealed the presence of pathogens most closely resembling Corynebacterium urinapleomorphum nov. sp., Staphylococcus saprophyticus and Helicobacter pylori. The latter colonies were confirmed as H. pylori by immunohistochemistry and biochemical methods. H. pylori cultured from the gallbladder exhibited both the same DNA fingerprinting and Western cagA gene sequence with ABC-type EPIYA (Glu-Pro-Ile-Tyr-Ala) phosphorylation motifs as isolates recovered from the gastric mucus of the same patient, suggesting that gastric H. pylori can also colonize other organs in the human body. Taken together, here we report, for the first time, the identification and characterization of a community consisting of live S. saprophyticus; C. urinapleomorphum, and H. pylori in the gallbladder of a patient with acute cholecystitis. Their potential infection routes and roles in pathogenesis are discussed.

Abstract
The exact pathogenesis of gallbladder adenomyomatosis is still lacking and some controversies over its diagnosis and treatment exist. Originally recognized as a precancerous lesion, adenomyomatosis is currently recognized by recent studies as a benign alteration of the gallbladder that is often associated with cholecystitis and cholecystolithiasis. Gallbladder carcinoma is an extremely malignant disease with a 5-year survival rate of less than 5%. Therefore, it is important to diagnose, differentiate, and confirm the relationship between adenomyomatosis and early-stage gallbladder carcinoma. However, the early clinical symptoms of adenomyomatosis are extremely similar to those of gallbladder stones and cholecystitis, increasing the difficulty to identify and treat this disease. This article summarizes the research progress on gallbladder adenomyomatosis, aiming to improve the understanding of the pathogenesis of adenomyomatosis and further provide insight for its clinical diagnosis and treatment.

Abstract
BACKGROUND Helicobacter pylori is coexisted with various diseases, including chronic gastritis, ulcer, and gastric cancer. Besides, chronic cholecystitis and cholelithiasis are extremely widespread over the world, which are considered as high health-care cost burdens of digestive diseases. Epidemiologic evidence on Helicobacter pylori infection in gallbladder increasing the risk of biliary diseases has been contradictory. AIM Conduct a meta-analysis of overall studies and investigate an association between Helicobacter pylori infection of the gallbladder with chronic cholecystitis/cholelithiasis. METHODS We used PubMed, EMBASE, and Cochrane library databases to identify all published studies before August 2017. Pooled odds ratios (OR) and corresponding 95% confidence intervals (CIs) were obtained using the random effects model. Heterogeneity, sensitivity, and stratified analyses were also performed. RESULTS Eighteen studies involving 1544 participants and 1061 biliary cases with chronic cholecystitis/cholelithiasis were included. Helicobacter pylori infection of the gallbladder was significantly associated with an increased risk of chronic cholecystitis and cholecystitis (OR = 3.022; 95% CI, 1.897-4.815; I2 = 20.1%). In addition, country-based subgroup analysis also showed a positive association between Helicobacter pylori positivity and chronic cholecystitis/cholelithiasis risk. The ORs (95% CIs) for Asian and non-Asian region studies were 3.75 (1.83-7.71) and 2.25 (1.29-3.89), respectively. CONCLUSION This meta-analysis suggests that infection of the gallbladder with Helicobacter pylori is closely related to an increased risk of chronic cholecystitis and cholelithiasis.

Abstract
BACKGROUND Biliary cancers are more common in females, and previous studies have suggested that Helicobacter pylori (H. pylori) exists in the biliary system. However, the effects of H. pylori infection and estrogen on the biological behaviors of human biliary epithelium mucosa remain unknown. The present study aimed to clarify their effects on the proliferation, apoptosis, migration and oxidative DNA damage of a human intrahepatic biliary epithelial cell (HIBEC) line in vitro. METHODS HIBECs were co-cultured with 17β-estradiol (at 10-9 mol/L, 10-7 mol/L, and 10-5 mol/L) and H. pylori (at MOI=0.5:1, 1:1, and 2:1) and continuously passaged until the 15th generation (approximately 45 days). Then, the following assays were performed. HIBEC proliferation was measured using the CCK-8 assay, plate clone-formation assay and by determining Ki-67 expression with immunocytochemistry; cell apoptosis and migration were investigated using Annexin-V/PI and transwell assays, respectively; and reactive oxygen species (ROS) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) production were detected by flow cytometry and immunofluorescence staining combined with confocal laser scanning microscopy, respectively. The results were the basis for evaluating the level of oxidative stress and the related DNA damage in HIBECs. RESULTS HIBECs maintained a normal morphology and vitality when treated with 17β-estradiol (at 10-9 mol/L) and H. pylori (at MOI=0.5:1 and 1:1). 17β-estradiol at 10-7 mol/L and 10-5 mol/L and H. pylori at MOI=2:1, by contrast, caused cell death. Compared with controls, HIBECs treated with 17β-estradiol (10-9 mol/L) and H. pylori (MOI=1:1) had a higher up-regulation of proliferation, Ki-67 expression, clone formation, migration activity and the expression of ROS and 8-OHdG and exhibited a down-regulation of apoptosis. The above effects were further increased when 17β-estradiol and H. pylori were combined (P<0.05). CONCLUSIONS H. pylori and 17β-estradiol, separately or in combination, promoted cell proliferation and suppressed apoptosis of HIBECs in vitro. The above phenomena might be related to oxidative stress and its subsequent DNA damage with H. pylori and 17β-estradiol.

Coinfection with Helicobacter pylori and Opisthorchis viverrini Enhances the Severity of Hepatobiliary Abnormalities in Hamsters. Infect Immun 2017; 85:IAI.00009-17.

Abstract
Persistent infection with Opisthorchis viverrini causes hepatobiliary abnormalities, predisposing infected individuals to cholangiocarcinoma (CCA). In addition, Helicobacter pylori is highly prevalent in most countries and is a possible risk factor for CCA; however, its role in enhancing hepatobiliary abnormality is unclear. Here, we investigated the effects of coinfection with H. pylori and O. viverrini on hepatobiliary abnormality. Hamsters were divided into four groups: (i) normal, (ii) H. pylori infected (HP), (iii) O. viverrini infected (OV), and (iv) O. viverrini and H. pylori infected (OV+HP). At 6 months postinfection, PCR and immunohistochemistry were used to test for the presence of H. pylori in the stomach, gallbladder, and liver. In the liver, H. pylori was detected in the following order: OV+HP, 5 of 8 (62.5%); HP, 2 of 5 (40%); OV, 2 of 8 (25%). H. pylori was not detected in normal (control) liver tissues. Coinfection induced the most severe hepatobiliary abnormalities, including periductal fibrosis, cholangitis, and bile duct hyperplasia, leading to a significantly decreased survival rate of experimental animals. The greatest thickness of periductal fibrosis was associated with a significant increase in fibrogenesis markers (expression of alpha smooth muscle actin and transforming growth factor beta). Quantitative reverse transcription-PCR revealed that the highest expression levels of genes for proinflammatory cytokines (interleukin-1 [IL-1], IL-6, and tumor necrosis factor alpha) were also observed in the OV+HP group. These results suggest that coinfection with H. pylori and O. viverrini increased the severity of hepatobiliary abnormalities to a greater extent than either single infection did.

Abstract
INTRODUCTION Helicobacter pylori (H.pylori) is associated with gastritis, peptic ulcer, gastric carcinoma and gastric lymphoma. Current literature describes presence of H.pylori in various extra-gastric locations and its association with many diseases. Apart from the conventional location of gastric and duodenal mucosa, H.pylori have been isolated and cultured from gallbladder. AIM Analysis of cholecystectomy specimens to detect H.pylori by means of immunohistochemical staining. MATERIALS AND METHODS There were a total of 118 cholecystectomy specimens received in the Department of Pathology in three months duration. We have performed immunostaining for H.pylori in 45 consecutive cases of cholecystectomy specimen. Clinical and other investigational information were retrieved from the medical records department. For each case, routine Haematoxylin and Eosin stain was studied. Immunohistochemistry (IHC) was done using purified polyclonal Helicobacter pylori antiserum. RESULTS Majority of the patients had undergone laparoscopic cholecystectomy for the presenting complaint of right hypochondrial pain. Multiple pigmented stones were present in majority (27/45) of them. Immunostain for H.pylori was positive in ten cases. Six of these cases had pigmented gall stones, two had stones not specified and in two of the cases there were no stones. CONCLUSION Helicobacter pylori is present in gall bladder and is commonly seen in association with stones. A more detailed study of cholecystectomy cases (both neoplastic and non-neoplastic) with serological, culture and molecular data of H.pylori is desirable to study the pathogenesis of cholecystitis, its association with gall stones and other gall bladder disorders.

Abstract
Helicobacter pylori (H. pylori) is an extremely common, yet underappreciated, pathogen that is able to alter host physiology and subvert the host immune response, allowing it to persist for the life of the host. H. pylori is the primary cause of peptic ulcers and gastric cancer. In the United States, the annual cost associated with peptic ulcer disease is estimated to be $6 billion and gastric cancer kills over 700000 people per year globally. The prevalence of H. pylori infection remains high (> 50%) in much of the world, although the infection rates are dropping in some developed nations. The drop in H. pylori prevalence could be a double-edged sword, reducing the incidence of gastric diseases while increasing the risk of allergies and esophageal diseases. The list of diseases potentially caused by H. pylori continues to grow; however, mechanistic explanations of how H. pylori could contribute to extragastric diseases lag far behind clinical studies. A number of host factors and H. pylori virulence factors act in concert to determine which individuals are at the highest risk of disease. These include bacterial cytotoxins and polymorphisms in host genes responsible for directing the immune response. This review discusses the latest advances in H. pylori pathogenesis, diagnosis, and treatment. Up-to-date information on correlations between H. pylori and extragastric diseases is also provided.

Abstract
AIM: To investigate the relationship between gallbladder stones and Helicobacter pylori (H. pylori) colonization of the gallbladder mucosa.
METHODS: H. pylori was detected in bile and gallbladder mucosa of 64 patients with gallbladder stones (experimental group) and 16 patients without gallbladder stones (control group). Polymerase chain reaction (PCR) was used to detect specific DNA fragments. Enzyme-linked immunoabsorbent assay (ELISA) was used to detect H. pylori IgG antibody. Immunohistochemistry was also used to detect H. pylori specific protein in gallbladder mucosa specimens.
RESULTS: ELISA analysis showed that the rate of H. pylori infection did not differ significantly between the experimental group and control group (48.44% vs 43.75%, P < 0.05). PCR analysis showed that the rate of H. pylori colonization of the gallbladder mucosa was significantly higher in the experimental group than in the control group (39.06% vs 12.50%, P = 0.04), but the rate of H. pylori in bile did not significantly between the two groups (59.38% vs 56.25%, P < 0.05). Immunohistochemistry analysis detected 19 positive cases in the experimental group and only 1 positive case in the control group.
CONCLUSION: H. pylori infection in the biliary tract does not play a major role in the process of gallbladder stone formation, but H. pylori colonization in the gallbladder mucosa is involved in the formation of gallstones.
