RESUMO
La gastropatía reactiva (GR) es producida principalmente por antiinflamatorios no esteroideos (AINEs) y reflujo biliar; puede presentarse aisladamente o coexistir con otros tipos de gastritis crónica (GC). Se revisaron 5.079 informes de estudios histopatológicos de biopsias gástricas de 4.254 pacientes, 825 en seguimiento con 2 a 7 estudios. La GR correspondió a 12,8% de los diagnósticos, las GC no atrófica (GCNA) y atrófica multifocal (GCAMF) correspondieron a 63,4% y 27,3% respectivamente. La infección por Helicobacter pylori se presentó en 61,6% de casos con GCNA, 51,5% con GCAMF, 18,5% con GR (p < 0.0001); en casos con coexistencia de GR+GCNA fue 43,9% y de 40,7% para GCAMF+GR. En pacientes en seguimiento aumentaron los diagnósticos de GR: 2 estudios con 22,2%, 3 estudios con 26,7% y 4-7 estudios con 28,8%; los hallazgos histológicos de GR en estos casos posiblemente son residuales, luego de la desaparición de los infiltrados inflamatorios por el tratamiento.
Reactive gastropathy (RG) is primarily produced by non-steroid antiinflammatory drugs (NSAIDs) and bile reflux. It can occur alone or coexist with other types of chronic gastritis (CG). 5,079 histopathological reports of gastric biopsies from 4,254 patients were reviewed: 825 of them had 2 to 7 follow-up studies. 12.8% of these patients were diagnosed with GR while 63.4% were diagnosed with chronic non-atrophic gastritis (CNAG) and 27.3% were diagnosed with chronic multifocal atrophic gastritis (CMAG). Helicobacter pylori infections were found in 61.6% of the cases with CNAG, 51.5% with CMAG, and in 18.5% of cases with GR only (p <0.0001). Among patients suffering from both RG and CNAG 43.9% had H. pylori infections. 40.7% of those suffering from both CMAG and RG were infected with H. pylori. During monitoring of patients RG diagnoses increased to 22.2% in the second study, 26.7% in the third study, and 28.8% in the fourth through seventh studies. Histological findings of RG in these cases are probably residual following disappearance of inflammatory infiltrates due to treatment.
