ABSTRACT

Introduction: The aim of this study was to assess the prevalence of occult HBV infection in HIV-positive patients in a centre in Southern Spain. Methods: The HBV serological markers were investigated in all the patients and the presence of HBV-DNA was tested by PCR in patients with isolated anti-HBc. Results: An isolated anti-HBc pattern was detected in 144/520 (27.7%) patients. HBV-DNA was detected in one of these patients (0.7%).Conclusions: In Southern Spain, there is a low prevalence of occult HBV infection among HIV-infected patients, despite increasing immigration from endemic countries (AU)


Introducción: El objetivo de este estudio fue evaluar la prevalencia de infección oculta por VHB en pacientes infectados por VIH del sur de España. Métodos: Se investigaron los marcadores serológicos para VHB y se analizó la presencia de ADN-VHB en los anti-HBc "solo". Resultados: El patrón anti-HBc "solo" fue detectado en 144/520 (27,7%) pacientes. El ADN-VHB fue detectado en un paciente (0,7%).Conclusiones: La prevalencia de infección oculta por VHB es baja entre los pacientes infectados por VIH a pesar del aumento en la inmigración desde países endémicos (AU)
