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 fi gures. Objective: To evaluate the response to the treatment for hepatitis in children with a history of cancer. Materials: 80 patients with a history of hemato-oncological treatment, from 2000 to 2008, with positive viral hepatitis serologies/for viral hepatitis. Results: 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. Conclusion: 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.
