- W1981246166 abstract "La globalización y los movimientos migratorios hacen que la hepatitis crónica B Age+ (HCBe+) cobre cada día mayor relevancia en nuestro entorno. Analizar las características epidemiológicas, evolución y respuesta al tratamiento con antivirales orales (AO) de los pacientes con HCBe+. Se analizaron 436 casos de infección crónica por el virus de la hepatitis B atendidos en el Hospital Universitario Ramón y Cajal desde 1990 hasta junio del 2012. Sesenta y cinco (14,9%) presentaban HCBe+. Siete pacientes en fase de tolerancia inmune no fueron tratados; los 58 restantes, sí. Fueron excluidos 4: 2 hepatitis agudas graves, una coinfección por VHC y otro por virus Delta. De los 54 restantes, 19 recibieron interferón con o sin AO y 35 solo AO. Dos tratados durante menos de un mes no fueron incluidos en el análisis. Este se realizó finalmente en 33 pacientes. Duración media del tratamiento: 46,81 meses (6-138). Lamivudina fue el fármaco más prescrito (39,39%), seguida de tenofovir (24,24%) y entecavir (21,21%). Edad media: 42,08 ± 14 años; varones 75,75% (25/33). El 57,57% (19/33) seroconvirtió el antígeno e y el 27,27% (9/33) eliminó el antígeno de superficie. No se objetivó la reaparición de este último tras un seguimiento medio de 35,6 meses. Resistencias: 8 casos en 7 pacientes, 7 a lamivudina y uno a adefovir. El 15% de las HCB en nuestro medio son e+. El tratamiento con AO logra una elevada tasa de seroconversión (57,57%) y un considerable porcentaje de pérdida del antígeno de superficie (27,27%). Due to globalization and migratory movements, HBeAg+ chronic hepatitis B is becoming increasingly important in Spain. To analyze the epidemiological features, progression, and treatment response to oral antiviral agents (OA) in HBeAg+ chronic hepatitis B patients in our area. We analyzed 436 patients with chronic hepatitis B infection followed up at the Ramón y Cajal Hospital from 1990 to June 2012. Sixty-five patients (14.9%) had HBeAg+ chronic hepatitis B. Seven patients in the immunotolerant phase were not treated, while the remaining 58 received treatment. Four patients were excluded: two due to severe acute hepatitis, one due to hepatitis C virus coinfection and another because of a Delta virus coinfection. Of the remaining 54 patients, 19 received interferon with or without OA, and 35 received only OA. Two patients treated for less than 1 month were not included in the analysis. The analysis was finally performed in 33 patients. The mean duration of treatment was 46.81 months (6-138). Lamivudine was the most frequently prescribed drug (39.39%) followed by tenofovir (24.24%) and entecavir (21.21%). The mean age was 42.08 ± 14 years and 75.75% (25/33) of the patients were male. Nineteen of 33 patients (57.57%) achieved seroconversion to anti-HBe, and 27.27% (9/33) showed clearance of HBsAg. There was no evidence of HBsAg reversion after a mean follow-up of 35.6 months. There were 8 cases of resistance in 7 patients: 7 to lamivudine and 1 to adefovir. Approximately 15% of chronic hepatitis B patients in our area are HBeAg+. Treatment with OA achieves a high seroconversion rate (57.57%) and a considerable percentage of HBsAg clearance (27.27%)." @default.
