Sanchez-Cuen JA, Canizalez-Roman VA, Leon-Sicairos NM, Irineo-Cabrales AB, Bernal-Magana G. Concordancia entre procedimientos diagnosticos invasivos para la infeccion por Helicobacter pylori en adultos. Salud Publica Mex 2015;57:352-357. Resumen Abstract Objective. Compare the strength of concordance be- tween culture, histology, rapid urease test for diagnosis of Helicobacter pylori infection and histopathological findings relationship and frequency of positivity among such diagnostic procedures. Materials and methods. Diagnostic test study. The study population were subjects with endoscopy and take samples of gastric antral. Rapid urease test (one sample), histology (two samples) and culture (two samples), and his- topathological findings of gastric mucosa were performed. Statistical design with Student's t, Fisher exact test, Kappa coefficient. Results. We reviewed 108 subjects, 28 (25.9%) men, 80 (74.1%) women, mean age was 49.1 years (SD 15.1). The Kappa coefficient was 0.729 and 0.377 between culture with histology and rapid urease test, respectively; likewise the Kappa coefficient was 0.565 between histology and rapid urease test. Conclusions. The strength of concordance was higher between histology with culture and rapid urease test; the most recommended being histology in clinical practice for the detection of Helicobacter pylori infection.
