English abstract Gastroesophageal reflux disease (GERD) is characterized by diverse symptoms. There is an evidence for a genetic component to GERD as supported by familial aggregation of this disease. OBJECTIVE To investigate whether certain human leucocyte antigen genes HLA-DRB1 are associated with GERD. METHODS Patients and controls were prospectively recruited from GIT center at Al-Kindy Teaching Hospital (Baghdad-Iraq) between January 2014 and July 2016. Sixty Iraqi Arab Muslims patients with a history of heartburn and dyspepsia compared with 100 Iraqi Arab Muslims controls. All study patients and control groups underwent upper gastrointestinal endoscopic examinations and their serums were analyzed for CagA antibodies Immunoglobulin G (IgG) for H. pylori. HLA-DRB1 genotyping were done to both groups. RESULTS A total of 60 patients with erosive gastritis; GERD (Grade II and III) were evaluated, together with 100 controls. There is a significant increase of H. pylori infection (P=0.0001) in GERD patients than control group. HLA-DRB1* 15:01 was significantly increased in GERD patients in comparison with control group and an increased frequency of HLADRB1*11:01 in control group compared with patients group. CONCLUSION There is an association between HLA-DRB1 *15:01 in GERD patients with H. pylori positive patients
Portuguese abstract A doença do refluxo gastroesofágico (DRGE) caracteriza-se por diversos sintomas. Há evidências de um componente genético para a doença de refluxo suportado pela agregação familiar desta doença. OBJETIVO Investigar se certos genes de antígeno de leucócito humano HLA-DRB1 são associados à DRGE. MÉTODOS Pacientes e indivíduos controles foram recrutados prospectivamente do centro GIT no Al-Kindy Hospital (Bagdá-Iraque) entre de 2014 janeiro e julho de 2016. Sessenta pacientes muçulmanos árabes iraquianos com uma história de azia e dispepsia foram comparados com 100 indivíduos controles. Todos os pacientes do estudo e grupos de controle foram submetidos a exames de endoscopia gastrointestinal alta e seus soros foram analisados para anticorpos CagA imunoglobulina G (IgG) para H. pylori. Genotipagem HLA-DRB1 foram feitas para ambos os grupos. RESULTADOS Um total de 60 pacientes com gastrite erosiva; GERD (grau II e III) foram avaliados, em conjunto com 100 controles. Houve aumento significativo de infecção pelo H. pylori (P=0,0001) em pacientes com DRGE em relação ao grupo controle. O HLA-DRB1* 15:01 aumentou significativamente em pacientes com DRGE em comparação com o grupo controle e houve uma maior frequência de HLADRB1* 11:01 no grupo controle em comparação com o grupo de pacientes com DRGE. CONCLUSÃO Há uma associação entre HLA-DRB1* 15:01 em pacientes com DRGE positivos para a infecção por H. pylori
