AbstractThis study investigated the clinical characteristics of Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis (HLH-HL). Clinical data of 8 patients with HLH-HL and 20 non-HLH-HL patients were included. All eight HLH-HL patients tested positive for plasma Epstein-Barr virus (EBV)-DNA and EBV-encoded small RNA (EBER), and six patients were positive for EBV-DNA in the peripheral blood mononuclear cells (PBMCs). Two out of the 20 non-HLH-HL patients were confirmed positive for EBER, and the remaining 18 patients were negative. Among the HLH-HL patients, five patients received ABVD (doxorubicin/bleomycin/vinblastine/dacarbazine) chemotherapy regimens in other hospitals, and their conditions were considered to be worse, for which reason they were transferred to our center, and three patients were treated with DEP (doxorubicin-etoposide-methylprednisolone) regimens to target HLH and were alive as of the writing of this article. Two patients were critically ill upon admission and were not able to undergo chemotherapy. Significant differences in survival time were observed between the HLH-HL and non-HLH-HL patients (P = 0.005). HL patients found positive for EBV (plasma/PBMCs EBV-DNA(+)/EBER(+)) may be more likely to develop HLH-HL. It may be beneficial to target HLH during the acute phase of HLH, followed by treating HL once the HLH condition has stabilized. HLH-HL patients have worse prognosis and higher mortality than non-HLH-HL patients.
