RESUMEN
La mayoría de los niños que padecen enfermedades hemato-oncológicas reciben múltiples transfusiones y esto aumenta el riesgo para adquirir estas infecciones. Por otro lado, en estos niños inmunosuprimidos la infección suele ser subclínica. Suele diagnosticarse al observar elevación de aminotransferasas. Evaluar la respuesta al tratamiento de hepatitis en niños con antecedentes oncológicos. 80 pacientes con antecedentes de tratamiento hematoncológico, del año 2000 a 2008 con serologías positivas para hepatitis viral. 39 (48,75%) presentan Hepatitis B, 19 (23,75%) Hepatitis C, 22 (27,75%) coinfección Hepatitis B y C. En el grupo HBV, 7 negativizaron espontáneamente DNAHBV. 20 recibieron tratamiento con diferentes esquemas 3 IFN, 4 lamivudina, 3 lamivudina + IFN, 10 Lamivudina + PEG; 7/20 negativizaron ADN VHB. 6/10 con tratamiento combinado negativizaron DNAHBV (60%). En el grupo con Hepatitis C, todos genotipo 1; 3 negativizaron RNAHCV espontáneamente; 10 recibieron tratamiento, 3/10 tratados con IFN + RIBAVIRINA y 7 con PEG + RIBAVIRINA. 1/3 y 4/7 (57,14%), negativizaron RNAHCV, respectivamente. En el grupo con coinfección, 14 tratados 2 IFN; 4 IFN + RIBAVIRINA; 8 PEG + RIBAVIRINA. 11/12 con esquema combinado culminaron tratamiento; negativizaron 1/11 (9%) DNAHBV y 5/11 (45,45%) RNAHCV. 8/80 desarrollaron complicaciones, cirrosis y hepatocarcinoma. Los pacientes pediátricos presentan respuesta al tratamiento para hepatitis B y C crónicas, similar al del adulto. Hubo diferencia estadísticamente significativa en la respuesta al tratamiento relacionado con el grado de inflamación en pacientes coinfectados. Cirrosis y hepatocarcinoma también se presentan en este grupo de edad...
ABSTRACT
Most children with hemato-oncological diseases receive multiple transfusions, and this increases the risk of acquiring these infections. On the other hand, in these immunosuppressed children the infection is usually subclinical. It’s usually diagnosed by observing an elevation in aminotransferases figures. To evaluate the response to the treatment for hepatitis in children with a history of cancer. 80 patients with a history of hemato-oncological treatment, from 2000 to 2008, with positive viral hepatitis serologies/for viral hepatitis. 39 (48,75%) had Hepatitis B, 19 (23,75%) Hepatitis C, 22 (27,75%) coinfection Hepatitis B and C. In the HBV group, 7 had spontaneous HBV-DNA negative, 20 received treatment with different schemes 3 IFN, 4 lamivudine, 3 lamivudine + IFN, 10 lamivudine + PEG; 7/20 had HBV-DNA negative. 6/10 with combined treatment had HBV-DNA negative (60%). In the group with Hepatitis C, all genotype 1; 3 had spontaneous HCV-RNA negative; 10 received treatment, of which 3/10 were treated with IFN + RIBAVIRIN and 7 with PEG + RIBAVIRIN. 1/3 and 4/7 (57.14%) had HCV-RNA negative, respectively. In the group with HBV/HCV co-infection, 14 patients treated 2 IFN, 4 IFN + RIBAVIRIN, 8 PEG + RIBAVIRIN. 11/12 with combined scheme ended treatment; 1/11 (9%) and 5/11 (45,45%) had HBV-DNA and HCV-RNA negative, respectively. 8/80 developed complications, such as, cirrhosis and hepatocellular carcinoma. Pediatric patients presented similar response to adult patients, to the treatment for chronic hepatitis B and C. There was a statistically significant difference in treatment response related to the degree of inflammation in coinfected patients. Cirrhosis and hepatocellular carcinoma are also evidenced in this age group...
