[Clinical analysis of 14 patients with lymphoma associated hemophagocytic syndrome].

The study was aimed to investigate the clinical characteristics, diagnosis and therapy of patients with lymphoma associated hemophagocytic syndrome (LAHS) so as to provide the clinical basis for improving its recognition and giving effective therapy. The clinical data of 14 patients with LAHS in Beijing Friendship Hospital, Capital Medical University during the period from June 2005 to May 2008 were collected, the informations including primary diseases, clinical manifestations, laboratory findings, therapy and outcome were analyzed retrospectively, the coincidence of each diagnostic index was compared before and after diagnosis. All 14 patients were given therapeutic regimens containing fludarabine, methylprednisolone and gammaglobulin (FDIg) after final diagnosis. The results indicated that 100% patients had abnormal changes on NK cell activity and sCD25 level in serum, but hemophagocytosis in less than 40% patients at early stage was found in bone marrow. Even after confirmed diagnosis of the disease, the percentage of patients with hemophagocytosis was not up to 50%. 9 out of the 14 patients had a good prognosis after treatment, and the other 5 patients died. It is concluded that the detection of NK cell activity and sCD25 level in serum may be valuable for the early diagnosis of LAHS, the hemophagocytosis is not necessary for the diagnosis of LAHS. Fludarabine combined with methylprednisolone and gamma globulin may provide a new strategy for LAHS therapy.
