Chronic active Epstein-Barr virus infection treated with PEGaspargase: A case report

BACKGROUND Chronic active Epstein-Barr virus infection(EBV)is a systemic EBV-positive lymphoproliferative disease,which may lead to fatal illness.There is currently no standard treatment regimen for chronic active EBV(CAEBV),and hematopoietic stem cell transplantation is the only effective treatment.We here report a CAEBV patient treated with PEG-aspargase,who achieved negative EBV-DNA.CASE SUMMARY A 33-year-old female Chinese patient who had fever for approximately 3 mo was admitted to our hospital in December 2017.EBV-DNA was positive with a high copy number.She was diagnosed with chronic active EB virus infection.PEGaspargase was administered at a dose of 1500 U/m2 at a 14-d interval,resulting in eradication of EBV for more than 6 mo.The effect of PEG-aspargase in this patient was excellent.CONCLUSION A chemotherapy regimen containing PEG-aspargase for CAEBV may be further considered.
