Resumo: | Background: H. pylori chronic atrophic gastritis is a premalignant lesion, and its staging, according to OLGA and OLGIM systems aims to identify patients at increased risk of developing gastric cancer and optimize their follow-up. GastroPanel®, serum biomarkers panel including pepsinogen I (PGI), pepsinogen II (PGII), Gastrin 17 (G17) and anti- H. pylori antibodies is a noninvasive test for adenocarcinoma risk assessment in chronic H. pylori gastritis patients. Objective: Prospective study to evaluate the concordance between OLGA and OLGIM grading systems, as well as to evaluate GastroPanel´s performance in patients with premalignant lesions secondary to H. pylori chronic gastritis in Brazil. Methods: Patients with H. pylori chronic gastritis with premalignant lesions confirmed by histology were recruited from the gastrointestinal clinic of a University Hospital. All participants underwent endoscopic examination with biopsies which were reported according to updated Sydney system and premalignant lesions grading systems (OLGA and OLGIM). Blood samples were collected for biomarkers serological analysis (GastroPanel®, Biohit, Helsinki, Finland). The cut off values used to define high risk patients were those recommended by the manufacturer: PGI ≤30 µm/L and PGI/PGII ≤3. Results: 41 patients were recruited: 28 women, 13 men, mean age 67.3 (47-89, SD: 9.6) years. By OLGA system, were obtained: OLGA 0 (n=1), OLGA I (n=7), OLGA II (n=17), OLGA III (n=9), and OLGA IV (n=7). By OLGIM system, were obtained: OLGIM 0 (n=14), OLGIM I (n=5), OLGIM II (n=10), OLGIM III (n=10), and OLGIM IV (n=2). Regarding histological staging among patients staged as low risk (OLGA/OLGIM 0, I and II) and high risk (OLGA/OLGIM III and IV) for gastric cancer development, the concordance rate found between both classifications was 85.4%. Considering high risk patients, those patients thus included in at least one of the systems the final distribution of our sample considered 24 low-risk and 17 high-risk patients for the development of gastric cancer. To determine by GastroPanel® whether the patient would be at low or high risk of developing gastric cancer, PGI showed a sensitivity, specificity and accuracy of 0.47 (95%CI: 0.26–0.69), 0.67 (95%CI: 0.47–0.82), and 0.58 (95%CI: 0.43–0.72), respectively, while PGI/PGII showed sensitivity, specificity and accuracy of 0.06 (95%CI: 0.01–0.27), 0.83 (95%CI: 0.64–0.93) and 0.51 (95%CI: 0.36–0.66), respectively. Conclusion: The histological classifications OLGA and OLGIM presented a substantial concordance rate among themselves. Simultaneous use of both histological classification systems increased the identification’s rate of high-risk patients.

GastroPanel®, painel de biomarcadores séricos incluindo pepsinogênio I (PGI), pepsinogênio II (PGII), gastrina 17 (G17) e anticorpos anti-H. pylori é um teste não invasivo para avaliação de risco de adenocarcinoma em pacientes com gastrite crônica por H. pylori. Objetivo: Estudo prospectivo para avaliar a concordância entre os sistemas de classificação OLGA e OLGIM, bem como avaliar o desempenho do GastroPanel em pacientes com lesões pré-malignas secundárias à gastrite crônica por H. pylori no Brasil. Métodos: Pacientes com gastrite crônica por H. pylori com lesões pré-malignas confirmadas por histologia foram recrutados da clínica gastrointestinal de um Hospital Universitário. Todos os participantes foram submetidos a exame endoscópico com biópsias que foram relatadas de acordo com o sistema de Sydney atualizado e sistemas de classificação de lesões pré-malignas (OLGA e OLGIM). Amostras de sangue foram coletadas para análise sorológica de biomarcadores (GastroPanel®, Biohit, Helsinki, Finlândia). Os valores de corte usados para definir pacientes de alto risco foram os recomendados pelo fabricante: PGI ≤30 µm/L e PGI/PGII ≤3. Resultados: 41 pacientes foram recrutados: 28 mulheres, 13 homens, idade média de 67,3 (47-89, DP: 9,6) anos. Pelo sistema OLGA, foram obtidos: OLGA 0 (n=1), OLGA I (n=7), OLGA II (n=17), OLGA III (n=9) e OLGA IV (n=7). Pelo sistema OLGIM, foram obtidos: OLGIM 0 (n=14), OLGIM I (n=5), OLGIM II (n=10), OLGIM III (n=10) e OLGIM IV (n=2). Em relação ao estadiamento histológico entre pacientes estadiados em baixo risco (OLGA/OLGIM 0, I e II) e alto risco (OLGA/OLGIM III e IV) para o desenvolvimento de câncer gástrico, a taxa de concordância encontrada entre as duas classificações foi de 85,4%. Considerando pacientes de alto risco, esses pacientes incluídos em pelo menos um dos sistemas a distribuição final de nossa amostra considerou 24 pacientes de baixo risco e 17 de alto risco para o desenvolvimento de câncer gástrico. Para determinar pelo GastroPanel® se o paciente teria risco baixo ou alto de desenvolver câncer gástrico, o PGI mostrou sensibilidade, especificidade e precisão de 0,47 (95% CI: 0,26–0,69), 0,67 (95% CI: 0,47–0,82) , e 0,58 (IC 95%: 0,43–0,72), respectivamente, enquanto PGI/PGII apresentou sensibilidade, especificidade e precisão de 0,06 (IC 95%: 0,01–0,27), 0,83 (IC 95%: 0,64–0,93) e 0,51 ( IC95%: 0,36–0,66), respectivamente. Conclusão: As classificações histológicas OLGA e OLGIM apresentaram uma taxa de concordância substancial entre si. O uso simultâneo de ambos os sistemas de classificação histológica aumentou a taxa de identificação de pacientes de alto risco. A análise de biomarcadores não foi eficaz para distinguir pacientes de baixo a alto risco na população estudada. Mais estudos são necessários para validar seu uso na prática clínica no Brasil.engUniversidade Federal de Minas GeraisUFMGBrasilHCL - HOSPITAL DAS CLINICASArquivos de GastroenterologiaGastrite atróficaHelicobacter pyloriÍndice de gravidade de doençaBiomarcadoresAlgoritmosAtrophic gastritisDiagnosisHelicobacter pyloriSeverity of illness indexBiomarkersAlgorithmsHelicobacter pylori chronic gastritis on patients with premalignant conditions: OLGA and OLGIM evaluation and serum biomarkers performanceGastrite crônica por Helicobacter pylori em pacientes com condições pré-malignas: avaliação dos sistemas OLGA e OLGIM e desempenho de biomarcadores séricosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/ag/a/xB9ZfV5q99SYDYGMPr5Rm6m/?lang=enMaria Clara de Freitas CoelhoHenrique Gomes RibeiroCélio Geraldo de Oliveira GomesFrederico Passos MarinhoAlfredo José Afonso BarbosaLuiz Gonzaga Vaz Coelhoapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/54674/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALHelicobacter pylori chronic gastritis on patients with premalignant conditions OLGA and OLGIM evaluation and serum biomarkers performance.pdfHelicobacter pylori chronic gastritis on patients with premalignant conditions OLGA and OLGIM evaluation and serum biomarkers performance.pdfapplication/pdf1661911https://repositorio.ufmg.br/bitstream/1843/54674/2/Helicobacter%20pylori%20chronic%20gastritis%20on%20patients%20with%20premalignant%20conditions%20OLGA%20and%20OLGIM%20evaluation%20and%20serum%20biomarkers%20performance.pdf550ba5f63e3b6a53f2baa0e434910d9aMD521843/546742023-06-07 16:45:41.721oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-06-07T19:45:41Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |

Background: H. pylori chronic atrophic gastritis is a premalignant lesion, and its staging, according to OLGA and OLGIM systems aims to identify patients at increased risk of developing gastric cancer and optimize their follow-up. GastroPanel®, serum biomarkers panel including pepsinogen I (PGI), pepsinogen II (PGII), Gastrin 17 (G17) and anti- H. pylori antibodies is a noninvasive test for adenocarcinoma risk assessment in chronic H. pylori gastritis patients. Objective: Prospective study to evaluate the concordance between OLGA and OLGIM grading systems, as well as to evaluate GastroPanel´s performance in patients with premalignant lesions secondary to H. pylori chronic gastritis in Brazil. Methods: Patients with H. pylori chronic gastritis with premalignant lesions confirmed by histology were recruited from the gastrointestinal clinic of a University Hospital. All participants underwent endoscopic examination with biopsies which were reported according to updated Sydney system and premalignant lesions grading systems (OLGA and OLGIM). Blood samples were collected for biomarkers serological analysis (GastroPanel®, Biohit, Helsinki, Finland). The cut off values used to define high risk patients were those recommended by the manufacturer: PGI ≤30 µm/L and PGI/PGII ≤3. Results: 41 patients were recruited: 28 women, 13 men, mean age 67.3 (47-89, SD: 9.6) years. By OLGA system, were obtained: OLGA 0 (n=1), OLGA I (n=7), OLGA II (n=17), OLGA III (n=9), and OLGA IV (n=7). By OLGIM system, were obtained: OLGIM 0 (n=14), OLGIM I (n=5), OLGIM II (n=10), OLGIM III (n=10), and OLGIM IV (n=2). Regarding histological staging among patients staged as low risk (OLGA/OLGIM 0, I and II) and high risk (OLGA/OLGIM III and IV) for gastric cancer development, the concordance rate found between both classifications was 85.4%. Considering high risk patients, those patients thus included in at least one of the systems the final distribution of our sample considered 24 low-risk and 17 high-risk patients for the development of gastric cancer. To determine by GastroPanel® whether the patient would be at low or high risk of developing gastric cancer, PGI showed a sensitivity, specificity and accuracy of 0.47 (95%CI: 0.26–0.69), 0.67 (95%CI: 0.47–0.82), and 0.58 (95%CI: 0.43–0.72), respectively, while PGI/PGII showed sensitivity, specificity and accuracy of 0.06 (95%CI: 0.01–0.27), 0.83 (95%CI: 0.64–0.93) and 0.51 (95%CI: 0.36–0.66), respectively. Conclusion: The histological classifications OLGA and OLGIM presented a substantial concordance rate among themselves.
