Fundamento

Estudiar el riesgo de transmitir el virus de la hepatitis B (VHB) a los receptores dehígados de donantes AgHBs negativos y anti-HBc positivos.

Pacientes y método

Se han analizado retrospectivamente los marcadores séricos del VHB (MHB) (AgHBs, anti-HBc y anti-HBs) de 43 donantes, junto con los 41 receptores de estos órganos. La determinación de MHB se realizó por ELISA, y el ADN del VHB por técnica de hibridación molecular.

Resultados

Trece sueros de donantes (30,2%) presentaron algún MHB: 6 anti-HBc y anti-HBs(13,9%), 4 anti-HBc (9%) y tres anti-HBs (6,9%). De los receptores que recibieron un injertosin MHB, ninguno desarrolló infección después del trasplante de hígado. De los 13 receptores de órganos con MHB, 9 han sido controlados durante 39 (DE 17) meses. Los 5 receptores de un injerto anti-HBc positivo, con anti-HBs o sin él, y que no presentaban MHB desarrollaron hepatitis B (100%). Los dos receptores de órganos anti-HBs positivos únicamente y sin MHB no desarrollaron infección (0%). Entre los receptores 15 tenían algún MHB antes del trasplante de hígado (31,7%); 5 de ellos tenían anti-HBs positivo antes del trasplante. Los dos receptores de este grupo que recibieron un injerto anti-HBc positivo no desarrollaron infección (0%).

Conclusiones

En este estudio la prevalencia de MHB entre los donantes y receptores es del 30,2 y del 31,7%, respectivamente. Los injertos anti-HBc positivos con anti-HBs o sin él transmitieronla enfermedad en el 100% de los receptores. La presencia de anti-HBs en el receptor protegió de la infección. Los injertos únicamente positivos para anti-HBs no ransmitieron la enfermedad.

Background

To study the hepatitis B virus (HBV) transmission from donors HBsAg–/AntiHBc+ to liver transplant recipients.

Patients and method

We studied retrospectively the HBV serological markers in 43 donors from our center and also the serological condition of the 41 recipients. The HBV serological markers were analyzed by ELISA and HBV DNA was detected by hybridation assays.

Results

13 donors samples showed some HBV serological markers: 6 anti-HBc and anti- HBs (13.9%), 4 anti-HBc (9%) and 3 anti- HBs (6.9%). There were no cases of hepatitis B amongliver recipients from donors with negative serological markers. Among the 13 recipients with HBV serological markers, 9 were followed during 39 (SD 17) months. The 5 recipients with no HBV markers, who received an anti- HBc+ with or without anti- HBs (100%) developed hepatitis B. The two liver recipients with anti-HBs solely, did not developed infection (0%). Of the 41 recipients, 15 had some HBV markers before transplant and two of them received an anti- HBc+ and did not develop the infection (0%).

Conclusions

In our study, the prevalence of serological HBV infection in donors and recipients was of 30.2 and 31.7%, respectively. Anti-HBc with or without anti-HBs donors transmitted the HBV infection in all the cases (100%) to the susceptible recipients. The presence of anti- HBs in recipients protected these against the infection. Only the anti-HBs positive donors didnot trasmit the HBV infection.
