Abstract

Introduction: Changes in the immune system during pregnancy have been associated with reactivation of the hepatitis B virus in women chronic hepatitis B infection not receiving antiviral therapy. The aim of this study is to examine the development of intrapartum and postpartum hepatitis B reactivation in pregnant patients not being treated for chronic hepatitis B.
Material and Methods: Pregnant women diagnosed with chronic hepatitis B and not receiving treatment between 2017 and 2022 in five centres in the east and southeast Turkey included in this study. In order to evaluate biochemical and viral reactivation from intrapartum and postpartum periods, patients with data for at least two periods were included in the study.
Results: Evaluations were made on 171 pregnant women diagnosed with chronic hepatitis B. Reactivation occurred in 43 (25.2%) patients, in the postpartum period in 14 (32.35%) and in the intrapartum period in 29 (67.44%). Reactivation occurred most often in the 3rd trimester (n: 13, 30.2%). A significant increase was observed in the alanine aminotransferase levels of the patients with reactivation in the first trimester compared to 6 months prepartum and in the second trimester compared to the first trimester (p=0.038, p=0.039, respectively). The prepartum HBV DNA level (cut-off point =192 IU/ml) of patients with HBeAg negativity was found to have diagnostic power for reactivation of 0.684 (95% CI: 0.575-0.792, p=0.002) with 65.9% sensitivity and 68.6% specificity. Viral reactivation was observed in the first trimester in one patient and hepatitis B surface antibody was seen in the postpartum period.
Conclusions: Asymptomatic viral reactivation occurred at the high rate of 25.1% in this series. To be able to identify reactivation as early as possible, pregnant patients should be followed up closely in the intrapartum and postpartum periods.

Resumen

Introducción: Los cambios en el sistema inmunológico durante el embarazo se han asociado con la reactivación del virus de la hepatitis B en mujeres con infección crónica por hepatitis B que no reciben terapia antiviral. El objetivo de este estudio es examinar el desarrollo de la reactivación de la hepatitis B intraparto y posparto en pacientes embarazadas que no reciben tratamiento para la hepatitis B crónica.
Material y Métodos: Mujeres embarazadas diagnosticadas de hepatitis B crónica y que no recibieron tratamiento entre 2017 y 2022 en cinco centros del este y sureste de Turquía incluidos en este estudio. Para evaluar la reactivación bioquímica y viral de los períodos intraparto y posparto, se incluyeron en el estudio pacientes con datos de al menos dos períodos.
Resultados: Se evaluaron 171 gestantes con diagnóstico de hepatitis B crónica. La reactivación ocurrió en 43 (25,2%) pacientes, en el puerperio en 14 (32,35%) y en el intraparto en 29 (67,44%). La reactivación ocurrió con mayor frecuencia en el tercer trimestre (n: 13, 30,2%). Se observó un aumento significativo en los niveles de alanina aminotransferasa de las pacientes con reactivación en el primer trimestre en comparación con los 6 meses preparto y en el segundo trimestre en comparación con el primer trimestre (p = 0,038, p = 0,039, respectivamente). Se encontró que el nivel de ADN del VHB antes del parto (punto de corte = 192 UI/ml) de pacientes con HBeAg negativo tenía un poder diagnóstico para la reactivación de 0,684 (IC del 95 %: 0,575-0,792, p = 0,002) con una sensibilidad del 65,9 % y una sensibilidad del 68,6 %. % especificidad. Se observó reactivación viral en el primer trimestre en una paciente y se observaron anticuerpos de superficie contra la hepatitis B en el período posparto.
Conclusiones: La reactivación viral asintomática ocurrió en la alta tasa de 25,1% en esta serie. Para poder identificar la reactivación lo antes posible, las pacientes embarazadas deben ser seguidas de cerca en los períodos intraparto y posparto.
