Objective: To study the relationship between human herpesvirus-6 (HHV-6) and lymphoma in China.
Methods: The specimens of paraffin-embedded lymphoma tissue, leukemia cell lines and normal blood donor peripheral blood lymphocytes(PBL) were examined for the presence of HHV-6 DNA sequence by polymerase chain reaction (PCR).
Results: Of the 52 cases lymphoma studied, HHV-6 DNA sequence was detected in 21 cases; of 43 normal PBL, HHV-6 DNA sequence was detected in 8 cases. The difference was statistically significant (P < 0.05). HHV-6 DNA sequence was also present in two leukemia cell lines.
Conclusion: The results suggest that HHV-6 may be related to lymphoma in China.
