RESUMO
BACKGROUND: Recent data on the prevalence of H. pylori infection in Jamaica are lacking. It is postulated that there has been a decline in the prevalence of H. pylori infection and its associated complications. We determined sociodemographic characteristics, prevalence of H. pylori infection and clinical outcomes among adults undergoing esophagogastroduodenoscopy (EGD) and histology at the University Hospital of the West Indies (UHWI) between May 2018 and December 2020. MATERIALS AND METHODS: A cross-sectional study of patients (≥18 years old), who underwent EGD and histological evaluation for H. pylori infection, was conducted. Associations of H. pylori positivity and gastric cancer with sociodemographic/clinical variables and endoscopic findings were determined by stepwise logistic regression using backward selection. Unadjusted and adjusted odds ratios with related 95% confidence intervals (Cis) were calculated for H. pylori positivity and gastric cancer status. RESULTS: There were 323 participants (mean age 58.6 ± 17.8 years, 54.2% females). H. pylori prevalence was 22.2% (n = 70 of 315), 5.6% had gastric neoplasia (GN), 15.5% gastric atrophy, 11.4% intestinal metaplasia and 3.7% dysplasia on histology. Mucositis (64.5%), gastric ulcer (14.9%), and duodenal ulcer (13.9%) were the most common endoscopic findings. Participants with peptic ulcer disease (PUD) (unOR = 4.0; p = .017), gastric cancer (unOR = 9.5; p = .003), gastric atrophy (unOR = 12.8; p < .001), and intestinal metaplasia (unOR = 5.0; p < .001) had a significantly higher odds of being H. pylori positive, but after multivariable analyses only gastric atrophy remained significant (aOR = 27.3; p < .001). Participants with mucositis had a significantly lower odds of gastric cancer (unOR 0.1; p = .035) while participants with dysplasia had significantly higher odds (unOR 8.0; p = .042), but these were no longer significant after multivariable analyses (aOR = 0.2; p = .156 and aOR = 18.9; p = .070, respectively). CONCLUSIONS: Histology based prevalence of H. pylori infection is lower than previously reported in Jamaica. Gastric atrophy is a significant predictor of H. pylori positivity.

CONTEXT: The prevalence of obesity has been increasing in modern society. Roux-en-y gastric bypass is a bariatric surgery that involves the exclusion of significant part of the stomach. Atrophy, intestinal metaplasia and gastric cancer have been associated with infection by Helicobacter pylori. OBJECTIVES: To evaluate the presence of endoscopy findings and histological changes in morbid obese patients for the presence of inflammatory cells, inflammatory activity, lymphoid hyperplasia, H. pylori infection, atrophy and intestinal metaplasia in the gastric mucosa. METHODS: Upper digestive endoscopy and gastric histopathological were studied in 126 obese patients in the preoperative evaluation for bariatric surgery. RESULTS: Upper digestive endoscopy abnormalities were diagnosed in 73/126 (57.9%) patients. In three patients (2.4%) the upper gastrointestinal endoscopy diagnosed gastric ulcer and one patient (0.8%) had duodenal ulcer. The histopathological from gastric biopsies of these obese patients showed 65.1% of mucosa inflammation, inflammatory activity in 50.0%, infection by H. pylori in 53.2%, lymphoid hyperplasia in 50.0% and atrophy and/or intestinal metaplasia in 16.7%. CONCLUSIONS: In present study, with routine preoperative upper gastrointestinal endoscopy and histopathological examination, were detected 57.9% patients with endoscopy abnormalities, high prevalence of infection by H. pylori (53%) and 16.7% of gastric atrophy and/or intestinal metaplasia.

CONTEXT: A prevalência de obesidade tem aumentado significativamente nos últimos anos. Bypass gástrico em Y-de-Roux, uma das técnicas cirúrgicas realizadas no tratamento da obesidade, envolve exclusão de parte do estômago. Atrofia, metaplasia intestinal e câncer gástrico têm sido associados com infecção pelo Helicobacter pylori. OBJETIVOS: Avaliar a prevalência de achados endoscópicos e alterações histopatológicas em pacientes obesos mórbidos em relação à presença de células inflamatórias, atividade inflamatória, hiperplasia linfóide, infecção pelo H. pylori, atrofia e metaplasia intestinal na mucosa gástrica. MÉTODOS: Achados na endoscopia digestiva alta e histopatologia gástrica foram analisados em 126 pacientes obesos na avaliação pré-operatória de cirurgia bariátrica. RESULTADOS: Anormalidades endoscópicas do trato digestivo superior foram diagnosticadas em 73/126 pacientes, com três pacientes (2,4%) apresentando úlcera gástrica e um paciente (0,8%) com úlcera duodenal. A histopatologia das biopsias gástricas dos obesos estudados revelou 65,1% de processo inflamatório na mucosa, atividade inflamatória em 50,0%; infecção pelo H. pylori em 53,2%, hiperplasia linfóide em 50,0%, atrofia e/ou metaplasia intestinal em 16,7%. CONCLUSÕES: No presente estudo, através de endoscopia digestiva alta e histopatologia de biopsias gástricas, foram detectados 57,9% de pacientes com anormalidades endoscópicas, prevalência de infecção pelo H. pylori em 53% e atrofia e/ou metaplasia intestinal em 16,7%.

Heterotopic gastric mucosa in the gallbladder is extremely unusual. In this study, we aimed to report a case of gastric heterotopia together with squamous metaplasia in the gallbladder of a 47-year-old female patient who experienced an intensive abdominal pain. He was admitted to the hospital for clinical treatment without any improvement. Ultrasonography showed a stone located in the gallbladder neck and dilatation of intrahepatic bile ducts, both hepatic ducts and common hepatic duct. Laparoscopic cholecystectomy was performed. In the microscopical examination, the epithelium of the gallbladder revealed an unspecified chronic cholecystitis. Besides, at the level of the gallbladder body, a heterotopic gastric mucosa contain chief, parietal and mucosal cells with cystic glands and squamous metaplasia was found. Actually the patient is in long-time follow-up, asymptomatic. We also review 96 other reports of HGM in the gallbladder in the international medical literature from 1934. As heterotopic tissue may promote carcinogenesis of the gallbladder, close attention should be paid to any occurrence of such lesions in this anatomical region. It appears that laparoscopic cholecystectomy may be unavoidable for patients affected by heterotopic gastric mucosa at the present time and care must be taken when a diagnosis is made based on intraoperative frozen sections.

La heterotopía de la mucosa gástrica (HGM) en vesícula biliar es extremadamente rara. En este estudio, reportamos un caso de heterotopía gástrica junto con metaplasia escamosa en vesícula biliar de un paciente femenino de 47 años que experimentó un dolor abdominal intenso. Lo admitieron al hospital para el tratamiento clínico sin ninguna mejoría. Ultrasonografía demostró un cálculo situado en el cuello de la vesícula y dilatación de conductos biliares intrahepáticos, los conductos hepáticos y conducto hepático común. Se realizó la colecistectomía por vía laparoscópica. En el exámen microscópico el epitelio reveló una colecistitis crónica inespecífica. Además, en el nivel del cuerpo de la vesícula biliar fue hallada una mucosa gástrica heterotópica con células principales, parietales, células mucosas con las glándulas enquistadas y metaplasia escamosa. El paciente está en el seguimiento a largo plazo, asintomático. Revisamos 96 informes de HGM en vesícula biliar en la literatura médica internacional a partir de 1934. El tejido heterotópico puede promover la carcinogénesis de la vesícula biliar, por lo cual se debe prestar atención a cualquier ocurrencia de tales lesiones en esta región anatómica. La colecistectomía laparoscópica puede ser inevitable para los pacientes afectados por la mucosa gástrica heterotópica actualmente y todo cuidado debe ser tomado cuando se hace un diagnóstico por secciones congeladas intraoperatorias.(AU)

Background: Multifocal chronic gastritis, associated to intestinal metaplasia, is considered a preneoplastic lesion, closely associated to intestinal type gastric cancer. Aim: To study the frequency of microsatellite instability (MSI) and loss of heterozygosity (LOH) in areas of chronic gastritis and intestinal metaplasia in gastric biopsies of patients without cancer. Material and methods: Gastric biopsy samples from 34 patients without cancer (22 with multifocal atrophic gastritis and 12 with diffuse antral gastritis), were studied. Glands from areas of chonic gastritis and intestinal metaplasia and lymphocytes, were collected using laser microdissection of paraffin embedded samples. The analysis of 15 mono and dinucleotide microsatellites was used to assess LOH and MSI. Results: LOH and MSI were found in some of the markers in 55% (12/22) and 59% (13/22) of cases with intestinal metaplasia, respectively. Only one of 12 areas with diffuse atrophic gastritis had MSI and a different area had LOH (p <0.05 or less, when compared with areas of multifocal atrophic gastritis). Three areas of normal epithelium in patients with multifocal atrophic gastritis, also had alterations. Most of these alterations were concordant with adjacent areas with intestinal metaplasia. Conclusions: LOH and MSI was found in areas of intestinal metaplasia in more than half of the studied cases and in few areas of atrophic gastritis without intestinal metaplasia. These findings suggest that genotypic alterations may precede phenotypic modifications and that intestinal metaplasia is a preneoplastic lesion (Rev Méd Chile 2003; 131: 1365-74).

OBJECTIVE: The pathophysiology of gastroesophageal reflux disease (GERD) has been studied extensively in patients with long-segment Barrett's esophagus (LSBE), but few reports have explored GERD pathophysiology in patients who have short-segment Barrett's esophagus (SSBE) or intestinal metaplasia at the cardia (IMC). We aimed to compare clinical, endoscopic, histological, and functional features in patients with LSBE, SSBE, and IMC. METHODS: We identified 582 patients who had intestinal metaplasia at the squamocolumnar junction in the distal esophagus and divided them into three groups based on the extent of columnar-lined esophagus observed endoscopically: 1) patients with IMC who had no columnar-lined esophagus (i.e., the squamocolumnar and gastroesophageal junctions coincided), 2) patients with LSBE who had >3 cm of columnar-lined esophagus, and 3) patients with SSBE who had <3 cm of columnar-lined esophagus. All patients had esophageal manometric evaluation, and 24-h esophageal pH monitoring was performed to determine the extent of acid and bile (bilirubin) reflux. RESULTS: There were 174 patients with IMC, 155 with LSBE, and 25 with SSBE. Compared to patients with LSBE and SSBE, patients with IMC had significantly lower frequencies of GERD symptoms, hiatal hernia, and erosive esophagitis; significantly higher lower esophageal sphincter pressures; and significantly shorter durations of acid and bile reflux. Between patients with SSBE and LSBE, significant differences were found in the frequency of hiatal hernia and duration of acid reflux (both greater in the patients with LSBE). Also, dysplasia was significantly more frequent in patients with LSBE than in those with SSBE or IMC. CONCLUSION: GERD symptoms, signs, and physiological abnormalities are found more often in patients with Barrett's esophagus than in those with IMC, and the duration of acid reflux in patients with LSBE is greater than that in patients with SSBE. These findings suggest that the extent of intestinal metaplasia in the esophagus is related directly to the severity of underlying GERD.
