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.

Hemophagocytic lymphohistiocytosis (HLH) is an aggressive and potentially fatal syndrome that results from inappropriate activation of lymphocytes and macrophages. It is characterized by fever, hepatosplenomegaly, cytopenias, hypertriglyceridemia, hypofibrinogenemia, and pathologic findings of hemo- phagocytosis in the bone marrow or other tissues. We report an adult HLH case admitted to hepatology department.

Hemophagocytic lymphohistiocytosis (HLH) is a lifethreatening disorder due to hyperinflammation resulting in infiltration of different organs with extensive hemophagocytosis. Severe coagulopathy was one of the main reasons for death in HLH. Over secretion of plasminogen activator by activated macrophages leads to hyperfibrinolysis. We reported a 36-year-old woman who was diagnosed as HLH probably secondary to lymphoma. Massive bleeding from gut and retroperitoneal area were not able to be controlled by conventional hemostatic treatments. This patient received one dose recombinant activated factor VII (rFVIIa) 3.6 mg (70 μg/kg). Hemostatic effect was achieved in 0.5 hour and lasted 24 hours. Prothrombin time (PT) and activated partial thromboplastin time (APTT) were quickly corrected to normal ranges. Fibrinogen level elevated from 0.5 g/L before using rFVIIa to 1.8 g/L 20 hours after. Although dexamethasone and etopside were administrated to treat HLH, this patient died from septic shock after persistent neutropenia. This suggests that rFVIIa may be effective in the management of intractable hemorrhage in patients with HLH.

We report a case of therapy-related acute myeloid leukemia after low-dosed topoisomerase II inhibitor (etoposide) treatment for hemophagocytic lymphohistiocytosis (HLH). A 62-yr-old female patient had previously been treated with a HLH-94 protocol containing a low-dose of etoposide (total dose of 300 mg/m2). Thirty-one months later, the patient was admitted to the hematology department with general weakness and upper respiratory infection symptoms. Peripheral blood smear and bone marrow study revealed acute monocytic leukemia. There was no evidence of myelodysplastic syndrome, and a cytogenetic study showed no chromosomal abnormalities.

OBJECTIVETo study the prognostic significance of coagulation disorders in children with hemophagocytic syndrome (HPS).

METHODSThirty-five children with HPS were retrospectively studied to analyze the etiology, clinical characteristics, laboratory results and treatment outcomes.

RESULTSAfter treatment, 27 of the 35 HPS patients survived, and the other 8 cases died. All cases were treated according to the HLH-2004 protocol, but etoposide (VP-16) was not used in 10 of them. The response rate in patients who received VP-16 (22/25, 88%) was significantly higher than that in those not receiving VP-16 (5/10, 50%) (P<0.05). Compared with the survival group, the dead group had significantly lower platelet count, fibrinogen level, and VP-16 utilization rate (P<0.05) but significantly longer activated partial thromboplastin time and prothrombin time (P<0.05).

CONCLUSIONSCoagulation function can be used as an indicator of disease outcome. It is essential for improving the clinical outcome of HPS to monitor the coagulation function during treatment, detect and correct abnormalities in time, and provide treatment strictly according to the HLH-2004 protocol.

OBJECTIVE: To investigate the clinical features of acute myeloid leukemia patients with hemophagocytic syndrome. METHODS: The clinical data of 2 patients with acute myeloid leukemia complicated with hemophagocytic syndrome were collected, and the clinical characteristics and treatment outcomes were analyzed. RESULTS: There were two patients with acute myeloid leukemia, including 1 male and 1 female，aged for 67 and 40 years old，respectively. Hemophagocytic syndrome occurred in one patient after induction therapy for acute myeloid leukemia and one patient after consolidation therapy. Both of the patients with hemophagocytic syndrome showed fever, hemocytopenia, high ferritin, high titer sCD25 levels and hemophagocytes in bone marrow. After achieved anti-infection, glucocorticoid, human immunoglobulin and etoposide regimens treatment, hemophagocytic syndrome was controlled in both of the two patients. One patient failed to induce acute myeloid leukemia and one patient achieved complete remission. CONCLUSION Acute myeloid leukemia complicated with hemophagocytic syndrome is rare. Early identification, early anti-infection combined with HLH94 regimen can control hemophagocytosis and improve prognosis.

Hemophagocytic syndrome (HPS) is an uncommon hematological disorder that manifests as fever, splenomegaly, and jaundice, with hemophagocytosis in the bone marrow and other tissues pathologically. Secondary HPS is associated with malignancy and infection, especially viral infection. The prevalence of cytomegalovirus (CMV) infection in ulcerative colitis (UC) patients is approximately 16%. Nevertheless, HPS in UC superinfected by CMV is very rare. A 52-year-old female visited the hospital complaining of abdominal pain and hematochezia for 6 days. She was diagnosed with UC 3 years earlier and had been treated with sulfasalazine, but had stopped her medication 4 months earlier. On admission, her spleen was enlarged. The peripheral blood count revealed pancytopenia and bone marrow aspiration smears showed hemophagocytosis. Viral studies revealed CMV infection. She was treated successfully with ganciclovir. We report this case with a review of the related literature.

OBJECTIVETo explore the characteristics and risk of etoposide-related leukemia in the treatment of hemophagocytic lymphohistiocytosis (HLH).

METHODClinical characteristics of a case with secondary acute promyelocytic leukemia (APL) were summarized and 10 cases of secondary leukemia after treatment for HLH from literature were analyzed.

RESULTThe child was diagnosed with Epstein-Barr virus associated HLH and received HLH-2004 protocol. The cumulative dose of etoposide (VP16) was 3520 mg/m(2). The patient was diagnosed with APL after 28 months of HLH.He achieved complete remission after induction chemotherapy of all-trans-retinoic acid and darubicin. Consolidated chemotherapy was continued. There were 10 reports of etoposide-related leukemia after treatment for HLH in the literature.Review of 11 cases treated with VP16, of which cumulative doses were 900-20 500 mg/m(2). The interval period between HLH and secondary leukemia was 24 months. The types of secondary leukemia included 1 case with acute lymphoblastic leukemia, 1 case with myelodysplastic syndrome and 9 cases of acute myeloid leukemia. The abnormalities of chromosome included 3 patients with 11q23, 3 APL patients with t (15, 17).Seven patients survived and 4 died.

CONCLUSIONThe latency period of etoposide-related leukemia is short. Acute myeloid leukemia and balanced chromosomal abnormality are common in etoposide-related leukemia. The risk factors for development of secondary leukemia are related to cumulative drug doses of etoposide, treatment schedules and co-administration of other antineoplastic agents.It is appropriate to keep suitable range of the cumulative dose of etoposide in HLH therapy in order to reduce the risk of therapy related leukemia.
