RESUMEN
BACKGROUND AND AIMS: Costa Rica is one of the countries with the highest incidence and mortality rates for gastric cancer. Helicobacter pylori infection rates are high in the whole country. We have previously shown that H. pylori CagA+ is significantly associated with atrophic gastritis (AG) of the antrum in a dyspeptic population. The aim of this work is to determine if other H. pylori virulence factors (vacA, dupA, oipA, iceA and babA2) are associated with atrophic gastritis (AG) or duodenal ulcer (DU). METHODS: The presence of virulence genes in Costa Rican H. pylori isolates was analyzed by PCR in 151 cultured strains from patients with dyspeptic symptoms. Endoscopic and histopathological diagnoses were available. Odds-ratio and 95% confidence intervals for AG patients vs. non-atrophic gastritis (NAG) or DU patients vs. no duodenal ulcer (NDU) patients were calculated. RESULTS: Amongst the studied isolates, 82% had the cagA+, 76.2% had the vacA s1m1, 97.0% had the oipA+, 21.0% had the icea1, 79.0% had the iceA2, 44.0% had the babA2+ and 76.0% the dupA+ genotypes. Infection with H pylori cagA+, dupA+, oipA+, iceA, babA2+, and vacA s1m1 genotypes was not associated with AG risk. The frequency of the dupA gene was 78.7 and 60.9% in isolates from patients with NDU and DU, respectively, and its presence was significantly associated with decreased risk of duodenal ulcer [odds-ratio: 0.33, pâ¯=â¯0.024, confidence interval 95% (0.11-0.85)]. CONCLUSION: H. pylori dupA genotype is inversely associated with DU risk in this population.

OBJECTIVE: To present and discuss the endoscopic and histological results, as well as the incidence of Helicobacter pylori and other diseases, indications and characteristics of upper digestive endoscopies performed in children. MATERIAL AND METHODS: Twenty-five endoscopies were performed in children aged six months to 11 years (mean 7.69 years), from February 2013 to January 2016. In 200 patients, endoscopies were diagnostic and serial biopsies were performed (esophagus, stomach and duodenum), in 120 of them. RESULTS: The indication of endoscopy was diagnosed in 88.89% of the patients, and in 26 patients, a therapeutic procedure was performed. The most frequent endoscopic findings were esophagitis in 49 patients, gastritis in 84 and duodenitis in 16 patients. Four duodenal ulcers were diagnosed. In the therapeutic endoscopies, six gastrostomies were performed, 14 foreign body withdrawals, five nasoenteral tube passages and esophageal dilatation. The H. pylori survey was performed by anatomopathological method and was positive in 26 (13%) of the 200 patients in whom it was searched. CONCLUSION: pediatric endoscopy is an important niche of the digestive endoscopy, where it is important to emphasize the relevance of the institutional structure that performs these procedures, in order to conduct them safely, being able to treat possible and feasible complications.

BACKGROUND: The genes jhp0940, jhp0945, jhp0947, and jhp0949 belong to the plasticity region of the Helicobacter pylori genome. Due to their prevalence in isolates from patients with gastritis, duodenal ulcer, and gastric cancer, they have been proposed as markers of gastroduodenal diseases. These genes are associated with pro-inflammatory cytokine induction through the NF-κB activation pathway. Nevertheless, the status of these genes is unknown in H. pylori isolates from children. The aim of the present work was to determine the frequency of the jhp0940-jhp0945-jhp0947-jhp0949 genes in H. pylori isolates from children. MATERIALS AND METHODS: We identified the jhp0940, jhp0945, jhp0947, and jhp0949 genes and the relationship of each with the virulence factors cagA, cagPAI, and dupA by PCR in 49 isolates of H. pylori from children. The results were corroborated using dot blots. In addition, we compared the prevalence of these genes with the prevalence in adults. RESULTS: The prevalence of jhp0940 (53.1%), jhp0945 (44.9%), jhp0947 (77.6%), and jhp0949 (83.7%) was determined in the isolates from children, as was the prevalence of the virulence genes cagA (63.3%), cagPAI (71.4%), and dupA (37.5%). No association was found between the four genes of the plasticity region and the virulence genes. The presence of the intact locus integrated by jhp0940-jhp0945-jhp0947-jhp0949 was very common among the isolates from children. CONCLUSION: The genes jhp0940, jhp0947, and jhp0949 were present in more than 50% of the H. pylori isolates, and the joint presence of jhp0940-jhp0945-jhp0947-jhp0949 was very frequent. The frequency of these genes in isolates from children could contribute to the virulence of H. pylori and the evolution of the infection.

BACKGROUND: A recent report has shown that the phylogenetic origin of Helicobacter pylori based on multi-locus sequence typing (MLST) was significantly associated with the severity of gastritis in Colombia. However, the potential relationship between phylogenetic origin and clinical outcomes was not examined in that study. If the phylogenetic origin rather than virulence factors were truly associated with clinical outcomes, identifying a population at high risk for gastric cancer in Colombia would be relatively straightforward. In this study, we examined the phylogenetic origins of strains from gastric cancer and duodenal ulcer patients living in Bogota, Colombia. METHODS: We included 35 gastric cancer patients and 31 duodenal ulcer patients, which are considered the variant outcomes. The genotypes of cagA and vacA were determined by polymerase chain reaction. The genealogy of these Colombian strains was analyzed by MLST. Bacterial population structure was analyzed using STRUCTURE software. RESULTS: H. pylori strains from gastric cancer and duodenal ulcer patients were scattered in the phylogenetic tree; thus, we did not detect any difference in phylogenetic distribution between gastric cancer and duodenal ulcer strains in the hpEurope group in Colombia. Sixty-six strains, with one exception, were classified as hpEurope irrespective of the cagA and vacA genotypes, and type of disease. STRUCTURE analysis revealed that Colombian hpEurope strains have a phylogenetic connection to Spanish strains. CONCLUSIONS: Our study showed that a phylogeographic origin determined by MLST was insufficient for distinguishing between gastric cancer and duodenal ulcer risk among hpEurope strains in the Andean region in Colombia. Our analysis also suggests that hpEurope strains in Colombia were primarily introduced by Spanish immigrants.

OBJECTIVES: To evaluate the prevalence of lesions and digestive complications secondary to the use of non-steroidal anti-inflammatory drugs (NSAIDs), the clinical profile seen for digestive complaints and the relation with the endoscopic findings. METHODS: Prospective, multicentric, open study, evaluating consecutively 1231 patients, divided as follows: group I - NSAID and group II - non-NSAID. All patients answered questionnaire to evaluate the onset, the type of clinical complaint, the use of medication and possible complications associated to digestive bleeding. RESULTS. A total of 1213 patients were evaluated. Among them, 65% were female and 13.1% were smokers; 15.6% mentioned they ingested alcoholic beverages. The main signs and symptoms reported were epigastralgy and pyrosis (67% and 62%, respectively). The upper gastrointestinal (UGI) endoscopy was normal in 3.9% in group I and in 10.7% in group II (p < 0.001). Patient who do not use NSAID will be 2.5 times more likely to have normal UGI endoscopy (p = 0.001). The presence of erosive or ulcer lesions in the stomach and duodenum was more frequent in group I. The incidence of lesions in the stomach when compared to the duodenum is observed (erosions: 49.12% vs. 13.60%, p = 0.001; ulcers: 14.04% vs. 11.84%, p = 0.05). The risk of digestive bleeding is 12 times higher (6.14% vs. 0.51%) in those who used NSAIDs, and the stomach is the site in which bleeding occurs more frequently. Conclusions. The frequency of gastric ulcer, duodenal ulcer and digestive bleeding was higher in patients who used NSAIDs. There was no connection found between endoscopic findings and dyspeptic symptoms.

BACKGROUND AND AIMS: Costa Rica has among the highest incidence and mortality rates for gastric cancer worldwide. The reasons for this are largely unknown. Polymorphisms of inflammatory response genes including genes encoding heat shock proteins (HSP) have been shown to be associated with the risk of gastric cancer in some populations. This study addresses the possible association between the HSP70-2 +1267 and HSP70-Hom +2437 polymorphisms and the risk of developing gastric cancer in a high-risk population in Costa Rica. METHODS: DNA from 39 individuals diagnosed with gastric cancer, 79 healthy controls, 55 individuals with chronic gastritis and 52 individuals with duodenal ulcer was genotyped for the polymorphisms HSP70-2 +1267 and HSP70-Hom +2437 by RFLP. Logistic regression analysis was used to determine possible associations with the diagnoses and lineal regression analysis to determine associations with blood pepsinogen (PGs) levels as measured by serology. RESULTS: The GA genotype of HSP70-2 was associated with increased risk of gastric cancer (OR = 3.42; 95% CI = 1.27-9.21; p = 0.015) and duodenal ulcer (OR = 2.57; 95% CI = 1.03-6.36; p = 0.042) as compared to the GG genotype. Persons with C carrier genotypes of HSP70-Hom were significantly less susceptible to gastric cancer than those with the TT genotype (OR = 0.29; 95% CI = 0.09-0.87; p = 0.027). The C carrier genotype was associated with lower PGI concentrations but none of the polymorphisms were associated with PGI/PGII. CONCLUSIONS: Polymorphisms of HSP70 genes are associated with the development of gastric cancer and duodenal ulcers in a population at high risk for gastric cancer in Costa Rica.

CONTEXT: In spite of Helicobacter pylori infection being the etiological cause of peptic ulcer and its high prevalence in Brazil, the prevalence of peptic ulcer disease has been poorly studied. OBJECTIVES: To verify the peptic ulcer disease prevalence in patients of a tertiary care hospital. METHODS: Diagnostic findings from 1,478 consecutive endoscopies were correlated with the urease test results for H. pylori infection diagnosis and demographic data in a total of 3,779 endoscopies performed in 2005. The mean age of the patients was 51.14 ± 16.46, being 613 (41.5%) men. RESULTS: Peptic ulcer was diagnosed in 494 (33.4%) patients with a mean age of 54.86 ± 14.53, 205 (52%) were men, being 391 (26.5%) duodenal ulcer and 103 (7%) gastric ulcer. Normal endoscopy was found in 272 (18.4%) patients with a mean age of 38.4 ± 15.22, being 49 (18%) men. The comparison of peptic ulcer group with the patients that had normal endoscopy revealed that H. pylori infection [P = 0.005; OR = 1.70; 95% CI = 1.17-2.47], male gender [P<0.0001; OR = 5.53; 95%CI = 3.67-8.34] and older age [P<0.0001; OR = 1.08; 95%CI = 1.06-1.09] increased the risk of peptic ulcers. The overall H. pylori prevalence was 53% (786). CONCLUSIONS: Prevalence of duodenal ulcer is high in a Brazilian population that had H. pylori infection associated with older age and male gender as important determinants to gastrointestinal diseases outcome. Future prospective studies should confirm these findings.

CONTEXTO: Apesar da infecção pelo Helicobacter pylori ser causa de úlcera péptica e de sua alta prevalência no Brasil, a prevalência da úlcera péptica tem sido pouco estudada. OBJETIVOS: Verificar a prevalência da doença ulcerosa péptica em pacientes de um hospital terciário. MÉTODOS: Achados diagnósticos de 1.478 endoscopias consecutivas foram correlacionados com os resultados de testes de urease para diagnóstico de infecção pelo H. pylori e dados demográficos num total de 3.779 endoscopias realizadas em 2005. A média de idade dos pacientes foi 51,14 ± 16,46, sendo 613 (41,5 por cento) homens. RESULTADOS: A úlcera péptica foi diagnosticada em 494 (33,4 por cento) pacientes com média de idade de 54,86 ± 14,53, 205 (52 por cento) eram homens, sendo 391 (26,5 por cento) úlceras duodenais e 103 (7 por cento) úlceras gástricas. Endoscopia normal foi achada em 272 (18,4 por cento) pacientes com média de idade de 38,4 ± 15,22, sendo 49 (18 por cento) homens. A comparação do grupo de úlcera péptica com os pacientes que tinham endoscopia normal revelou que a infecção pelo H. pylori [P = 0,005; OR = 1,70; 95 por cento CI = 1,17-2,47][ign], gênero masculino [P<0,0001; OR = 5,53; 95 por cento CI = 3,67-8,34][ign] e idade mais avançada [P<0,0001; OR = 1,08; 95 por cento CI = 1,06-1,09] aumentaram o risco de úlceras pépticas. A prevalência de infecção pelo H. pylori no total foi de 53 por cento (786). CONCLUSÕES: A prevalência da úlcera duodenal é alta numa população brasileira de um hospital terciário que teve a infecção pelo H. pylori, idade avançada e gênero masculino como determinantes importantes de evolução para doença gastrointestinal. Estudos futuros prospectivos devem confirmar esses achados.

BACKGROUND: Helicobacter pylori infection is one of the most common infections worldwide and is associated with gastric cancer and peptic ulcer. Bacterial virulence factors such as CagA have been shown to increase the risk of both diseases. Studies have suggested a causal role for CagA EPIYA polymorphisms in gastric carcinogenesis, and it has been shown to be geographically diverse. We studied associations between H. pylori CagA EPIYA patterns and gastric cancer and duodenal ulcer, in an ethnically admixed Western population from Brazil. CagA EPIYA was determined by PCR and confirmed by sequencing. A total of 436 patients were included, being 188 with gastric cancer, 112 with duodenal ulcer and 136 with gastritis. RESULTS: The number of EPIYA C segments was significantly associated with the increased risk of gastric carcinoma (OR=3.08, 95% CI=1.74 to 5.45, p<10-3) even after adjustment for age and gender. Higher number of EPIYA C segments was also associated with gastric atrophy (p=0.04) and intestinal metaplasia (p=0.007). Furthermore, patients infected by cagA strains possessing more than one EPIYA C segment showed decreased serum levels of pepsinogen I in comparison with those infected by strains containing one or less EPIYA C repeat. Otherwise, the number of EPIYA C segments did not associate with duodenal ulcer. CONCLUSIONS: Our results demonstrate that infection with H. pylori strains harbouring more than one CagA EPIYA C motif was clearly associated with gastric cancer, but not with duodenal ulcer.Higher number of EPIYA C segments was also associated with gastric precancerous lesions as demonstrated by histological gastric atrophic and metaplastic changes and decreased serum levels of pepsinogen I.

The dupA of Helicobacter pylori has been suggested as a virulence marker associated with the development of duodenal ulcer disease. However, the studies performed in different geographical areas have shown that there are variations in the prevalence of dupA and its association with H. pylori clinical outcomes. Our group did not observe associations between the presence of dupA and H. pylori clinical outcomes in Brazil. On the other hand, we observed 2 mutations in the sequence of dupA that lead to stop codons: a deletion of an adenine at position 1311 and an insertion of an adenine at position 1426 of the gene. Our aim was to evaluate associations of the presence of dupA with duodenal ulcer and gastric cancer, considering dupA-positive only those H. pylori strains that do not have the mutations in the gene sequence. We also evaluated the effect of infection with a strain carrying an intact dupA on the gastric mucosa histology and IL-8 gastric levels. Colonization with strains that had the intact dupA was negatively associated with gastric carcinoma (p=0.001, OR=0.32, 95% CI=0.16-0.66). The presence of dupA was also associated with an increased degree of antral mucosa inflammation (p=0.01) and with decreased corpus atrophy (p<0.01) as well as with increased gastric mucosa IL-8 levels (p=0.04). In conclusion, the infection with a H. pylori strain containing the dupA without the stop codon polymorphisms is associated with a lower risk of development of gastric carcinoma in Brazilian subjects.

OBJECTIVES: To evaluate the clinical, epidemiological and endoscopic characteristics of the Helicobacter pylori (Hp) negative peptic ulcer disease. METHODS: In this cross sectional study we included 651 patients diagnosed of peptic ulcer disease between January 2000 and December 2005. The diagnosis of Hp infection was established by histology. Clinical and epidemiological characteristics of patients with and without Hp infection were compared. RESULTS: Males prevailed (69%). Hp negative ulcers were older (57.73 +/- 19.44 years old vs 50.26 +/- 18, 64 years old, P < 0.001). Clinical characteristics did not differ among both groups. Duodenal ulcer prevailed in Hp positive patients (56.5%) and gastric ulcer in Hp negative patients (53.5%). Multiple ulcers and intestinal metaplasia were more frequently found in Hp negative cases [9.3% vs 4.5% (P = 0.015) and 34.5% vs 22.1% (P = 0.001), respectively]. CONCLUSION. Hp negative peptic ulcer disease is found in older patients, with a higher frequency of gastric ulcers, multiple lesions and intestinal metaplasia.

RACIONAL: A úlcera duodenal sempre representou uma doença muito prevalente entre as enfermidades digestivas, em qualquer parte do mundo. A prevalência média era de aproximadamente 10 por cento da população mundial. A partir do início dos anos 90, a literatura, tanto européia como norte-americana, passou a demonstrar sua redução gradativa entre seus países. OBJETIVO: Demonstrar, através de análise retrospectiva, a prevalência anual da úlcera duodenal nos últimos 10 anos em um Serviço de Endoscopia Digestiva que é referência para o sistema público de saúde da cidade de Porto Alegre, municípios da Grande Porto Alegre e outras cidades vizinhas da mesma. Os dados analisados são de março de 1996 até dezembro de 2005. MÉTODOS: Estudo retrospectivo transversal, com análise documental de diagnósticos endoscópicos efetuados em endoscopia digestiva alta, no referido Serviço. Foi feita a análise retrospectiva de diagnósticos endoscópicos efetuados em 13.130 pacientes submetidos a endoscopia digestiva alta no período de março de 1996 a dezembro de 2005. A classificação de Sakita foi utilizada para o estádio do grau evolutivo da úlcera duodenal e foi considerado por ela acometido o paciente com a lesão no estágio A1, até o estágio S1, inclusive. Observou-se também a prevalência nos dois sexos, na raça, o percentual médio total nos 10 anos, além da prevalência anual. Para verificar se houve significância estatística dos resultados observados nos diferentes períodos, foi aplicado um teste de regressão linear ("linear regression model"). RESULTADOS: Observou-se decréscimo gradativo dos percentuais de prevalência da úlcera duodenal, ano após ano, iniciando-se em 1996 com 8,6 por cento e se encerrando no final de 2005, com 3,3 por cento. A exceção do período foi observada no ano de 2003 quando houve um acréscimo, comparando-se com o decréscimo gradativo dos 6 anos anteriores. Mas já, a partir do período seguinte (2004), a queda gradativa voltou a ser observada...
BACKGROUND: The duodenal ulcer always represented a very prevalent pathology among the gastrointestinal tract diseases worldwide. The average prevalence is approximately 10 percent of the world population. In the 90s the literature (both European and North American) begin to show a crescent reduction of this prevalence in many countries. AIM: To show through a retrospective analysis the annual prevalence of the duodenal ulcer in the last 10 years in a Digestive Endoscopy Service which is referred to public medical system in Porto Alegre and its suburban area and countryside of the State of Rio Grande do Sul, Brazil. The data analyzed is from March 1996 to December 2005. Specific data: transversal retrospective study with documented analysis of endoscopic diagnosis of upper gastrointestinal endoscopy. METHODS: A retrospective analysis of the diagnosis of the 13.130 procedures of upper gastrointestinal endoscopy between 1996 and 2005. The Sakita classification was used to verify the duodenal ulcer activity taking into consideration the patients who have lesions on A1 to S1 levels. To verify if there was a statistical significant results, a linear regression test was done (linear regression model). RESULTS: A gradate decrease of the prevalence percentuals was observed, year after year, it began with 8.3 percent of prevalence in 1996 and finished with 3.3 percent in the beginning of 2006. The average annual reduction of this prevalence was calculated following the regression test and it was placed in the 1.3 percent a year in the studied period of time. In 2003, in an isolated way, it was an exception in the decrease of the percentage because it presented a prevalence increase of (6.5 percent) comparing to the first 6 years of study. CONCLUSION: In this study it was observed a decrease of duodenal ulcer prevalence, 1.3 percent a year to be more accurate in 10 years of study, showing a statistical significance in the linear regression test.

BACKGROUND: Nonsteroidal anti-inflammatory drugs are widely used in Brazil in spite of the known risks associated with their use, but investigation of their side effects conducted in this country has been far from sufficient. This study investigates the use of NSAIDs among patients undergoing upper endoscopy in the Hospital das Clínicas of the Federal University of Minas Gerais and the association of this use with the endoscopic diagnosis of gastric erosions, gastric erosions with hematin pigmentation, and gastric ulcer. METHODS: The cross-sectional methodological approach was used; 533 patients aged 17 or older were interviewed, between June and December, 2000. Data were submitted to bivariate and multivariate analyses. RESULTS: More than two thirds of the interviewed population reported the use of nonsteroidal anti-inflammatory drugs in a period of 1 month before the upper endoscopy. The most used nonsteroidal anti-inflammatory drugs were acetylsalicylic acid and diclofenac. An association was clearly shown between the use of these drugs and the occurrence of the studied lesions, with the latter attaining significance. There was also a significant association between nonsteroidal anti-inflammatory drugs use for a period greater than 15 days and the occurrence of the gastric lesions, with a higher odds ratio than for the other comparisons. CONCLUSIONS: The results suggest that nonsteroidal anti-inflammatory drugs have a significant association with the occurrence of the gastric lesions and point to the need of further study of this issue in Brazil.

INTRODUÇÃO: No Brasil são bastante evidentes os riscos associados ao uso de medicamentos. No entanto, tal questão não é devidamente privilegiada no campo da investigação científica. O presente estudo se refere ao uso de antiinflamatórios não-esteróides, fármacos amplamente utilizados no país. O objetivo foi investigar o uso de antiinflamatórios não-esteróides entre pacientes submetidos à endoscopia digestiva alta no Hospital das Clínicas da Universidade Federal de Minas Gerais e sua associação com a ocorrência de erosões gástricas, erosões gástricas com pigmento de hematina e úlcera gástrica. MÉTODOS: Estudo transversal em que 533 pacientes com idade igual ou superior a 17 anos foram entrevistados no período de junho a dezembro de 2000. Os dados foram submetidos às análises bivariada e multivariada. RESULTADOS: Mais de dois terços da população entrevistada relatou o uso de antiinflamatórios não-esteróides no período de um mês anterior à endoscopia digestiva alta. Os antiinflamatórios mais utilizados foram o ácido acetilsalicílico e o diclofenaco. Evidenciou-se uma associação positiva e significativa entre o uso desses fármacos e a ocorrência das lesões em questão. Ao se avaliar a associação entre o uso de antiinflamatórios não-esteróides por um período superior a 15 dias e a ocorrência das lesões gástricas, esta foi positiva e significativa, apresentado odds ratio superiores àqueles apresentados para as associações anteriores. CONCLUSÕES: Os resultados sugerem que os antiinflamatórios não-esteróides têm uma associação significativa com a ocorrência de lesões gástricas e apontam para a necessidade de aprofundamento no estudo desta questão no Brasil.

BACKGROUND AND AIM: Peptic ulcer disease (PUD) affects 10% of the world population. Helicobacter pylori infection and the use of a nonsteroidal anti-inflammatory drug (NSAID) are the principal factors associated with PUD. The aim of the present study was to evaluate a cohort of patients with PUD and determine the association between H pylori infection and NSAID use. PATIENTS AND METHODS: The medical charts of patients with endoscopic diagnosis of PUD were retrospectively reviewed from September 2002 to August 2003. Patients were divided into three groups according to ulcer etiology: H pylori infection (group 1); NSAID use (group 2); and combined H pylori infection and NSAID use (group 3). RESULTS: One hundred two patients were evaluated: 36 men (35.3%) and 66 women (64.7%). Forty patients had H pylori infection, 43 had used NSAIDs and 15 had combined H pylori infection and NSAID use; four patients with ulcers secondary to malignancy were excluded. The frequency of women was significantly higher in group 2 (P=0.01). The mean age of patients in group 1 was significantly lower than in the other two groups (P=0.003). PUD developed earlier in group 3 than in group 2 (5.0+/-4.7 months versus 1.4+/-2.1 months, respectively, P=0.018). Thirty-two patients (32.7%) had bleeding peptic ulcer. Group 2 had a higher risk of bleeding peptic ulcer than the other two groups (P=0.001). CONCLUSIONS: The development of PUD was observed earlier in the combined H pylori and NSAID group than in patients with only NSAID use. This suggests a synergic effect between the two risks factors in the development of PUD.

AIM: To determine the prevalence of peptic ulcer and gastric adenocarcinoma in a population of middle and high socio-economic status in Lima, Peru, between 1985 and 2002. MATERIAL AND METHODS: The prevalence of gastroduodenal ulcer and gastric adenocarcinoma was determined after studying by esophagogastroduodenoscopy 31,446 patients at the Policlínico Peruano Japonds (PPJ) between 1985 and 2002. All patients had chronic upper gastrointestinal symptoms and had endoscopically proven diagnosis of active peptic ulcer or histological diagnosis of gastric adenocarcinoma. RESULTS: Analysis of PPJ population identified a decrease in the prevalence of gastric ulcer and duodenal ulcer from 3.15% and 5.05% respectively in 1985, to 1.62% and 2.00% respectively in 2002. Gastric adenocarcinoma prevalence also decreased from 3.19% in 1988 to 0.92% in 2002. The prevalences of gastric ulcer (OR = 1.49, 95% IC 1.26-1.77, p < 0.001), duodenal ulcer (OR = 1.32, 95% IC 1.15-1.51, p < 0.001) and gastric adenocarcinoma (OR = 1.53, 95% IC 1.25-1.86, p < 0.001), decreased in the last eight years. CONCLUSIONS: Over the study period, there was a significant decrease in the prevalence of peptic ulcer and gastric adenocarcinoma at the Policlinico Peruano Japonés, where patients from middle and high socio economic status are attended.
