ABSTRACT

Se realizó un estudio en 723 muestras serológicas recibidas del Policlínico Docente “28 de Enero” en el período de enero de 1995 a enero de 1996, mediante el método inmunoenzimático ELISA para detectar el inmunosistema de superficie del virus de hepatitis B. Se encontraron 72 personas con anticuerpos contra el virus de la hepatitis B sin haber sido vacunados anteriormente y 4 pacientes infectados con este virus. A partir de estos, se estudiaron 61 familias, 260 muestras en el pesquisaje secundario, detectándose 6 nuevos antígenos, y 26 anticuerpos en personas no vacunadas. De los pacientes con hepatitis B, solo en 2 existían antecedentes epidemiológicos, 1 con transaminasa glutámica pirúvica elevada y 60 % con antigenemia alta. La búsqueda activa de reservorios asintomáticos en los convivientes de pacientes infectados por el virus de la hepatitis B puede contribuir a la eliminación y futura erradicación de la enfermedad.


A study of 723 serological samples received at “28 de Enero” Teaching Polyclinic from January 1995 to January 1996 was conducted by ELISA to detect the surface immunosystem of the hepatitis B virus. 72 persons with antibodies against the hepatitis B virus that had not been previously vaccinated, and 4 patients infected with this virus were detected. Starting from them, 61 families were studied, 260 samples were analyzed in the secondary screening, 6 new antigens were found, and 26 antibodies were detected in non-vaccinated persons. Of the patients with hepatitis B, only 2 had epidemiological history, 1 presented elevated glutamic piruvic transaminase and 60 % high antigenemia. The active search for asymptomatic reservoirs among those living with hepatitis B infected patients may contribute to the elimination and future erradication of the disease.
