Persistent hepatitis e virus genotype 4 infection in a child with acute lymphoblastic leukemia.

ABSTRACT:

Introduction

In general, the hepatitis E virus (HEV) causes acute, self-limiting hepatitis. Prolonged and chronic infections caused by HEV genotype 3 have been found in some immunosuppressed patients in developed countries.

Case presentation

Here we report a Chinese boy with acute lymphoblastic leukemia, who developed hepatitis E during a period of intensive chemotherapy.

Sequence analysis of the viral RNAs revealed the reactivation of the HEV genotype 4d strain, indicating viral persistence in the patient.

Conclusions

To our knowledge, this is the first chronic case confirmed by the prolonged presence of
