ABSTRACT

BACKGROUND: Gastroesophageal reflux disease develops when the stomach contents causes troublesome symptoms and complications. Mild forms are non-erosive and erosive esophagitis, and severe forms are Barrett's esophagus and Esophageal adenocarcinoma. Matrix metalloproteinases are endopeptidases that can degrade components of the extracellular matrix, they play an important role in tumor invasion as well as in metastasis. OBJECTIVE: To correlate the expression of metalloproteinase 9 (MMP-9) in esophageal biopsies from patients with mild and severe forms of Gastroesophageal reflux disease. METHOD: Cross-sectional study. The expression of MMP-9 was determined in biopsies of esophageal tissue of patients with mild and severe GRD. The included variables were age, sex, diagnosis, smoking and alcoholic habits, body mass index (BMI) and expression of MMP-9. Descriptive statistics was performed, Kappa for concordance in diagnosis as well as X2. RESULTS: There were 50 patients, 32 (64%) men and 18 (36%) women, mean age 52.13 ± 14.75 years of age. 12 (24%) with smoking and 7 (14%) with alcoholism. Average BMI was 26.71 ± 4.07 kg/m2 (15 to 33); 40 (80%) with obesity. The inter observer concordance for histopathological diagnosis was 1.0 and 0.84 for esophagitis degrees. 27 (54%) patients had esophagitis, 16 (32%) Barrett's esophagus and 7 (14%) esophageal cancer. There was expression of MMP-9 in four patients with esophagitis, five with Barrett's esophagus and five with esophageal cancer. Statistical significance was found between the expression of MMP-9 and smoking (p = 0.011) and histopathological diagnosis (p = 0.052). CONCLUSIONS: The expression of MMP-9 is most common in severe forms compared to the mild forms of GRD.


ANTECEDENTES: La enfermedad por reflujo gastroesofágico (ERGE) se desarrolla cuando el contenido estomacal ocasiona síntomas molestos o complicaciones. Las formas leves son esofagitis no erosiva y erosiva; las graves, esófago de Barrett y adenocarcinoma esofágico. Las metaloproteinasas de la matriz degradan componentes de la matriz extracelular, y tienen un papel importante en la invasión tumoral y la metástasis. OBJETIVO: Relacionar la expresión de la metaloproteinasa-9 (MMP-9) en biopsias esofágicas de pacientes con formas leves y graves de ERGE. MÉTODO: Estudio transversal. Se determinó la expresión de MMP-9 en biopsias esofágicas de pacientes con ERGE grave y leve. Las variables fueron edad, sexo, diagnóstico, tabaquismo, alcoholismo, índice de masa corporal (IMC) y expresión de MMP-9. Se realizó estadística descriptiva, concordancia para el diagnóstico y prueba de ji al cuadrado. RESULTADOS: 50 pacientes, 32 (64%) hombres y 18 (36%) mujeres, con edad media de 52.13 ± 14.75 años. Doce (24%) fumadores y 7 (14%) con alcoholismo. El IMC promedio fue de 26.71 ± 4.07 kg/m2 (rango: 15-33); 40 (80%) eran obesos. La concordancia entre observadores para el diagnóstico histopatológico fue de 1.0, y de 0.84 para esofagitis. Veintisiete (54%) tuvieron esofagitis, 16 (32%) esófago de Barrett y 7 (14%) cáncer de esófago. Hubo expresión de MMP-9 en cuatro pacientes con esofagitis, cinco con esófago de Barrett y cinco con cáncer esofágico. Encontramos diferencia estadísticamente significativa entre la expresión de MMP-9 y el tabaquismo (p = 0.011) y el diagnóstico histopatológico (p = 0.052). CONCLUSIONES: La expresión de MMP-9 es más frecuente en las formas graves que en las leves de ERGE.
