Objective To analyze the clinical characteristics, risk factors and prevention measures of nosocomial infection in senile patients with hematologic disorders. Methods The clinical data of 581 senile patients with hematologic disorders from July 2005 to June 2007 were retrospectively analyzed. Results The nosoeomial infection rate was 30.5%(177/581). The 581cases developed nosocomial infection for 254 times [43.7% (254/581)]. Lower respiratory tract infection was the most frequent infection site, followed by intestinal infection and upper respiratory infection. The species were predominated by Gram-negative bacillus (67.1%) . The risk factors of nosocomial infection were non-remission of malignant diseases,chronic underlying diseases, long time hospitaliation, community infection, granulocytopenia, invasive manipulation and application of adrenocortical hormone and antibiotic. Conclusions The nosoeomial infection rate is high in senile patients with hematologic disorders and it can be decreased by taking prevention measures according to the risk factors.

Objective: To explore the relation of the serum level of sIL-2R in relapse patients with acute lymphoblastic leukemia(ALL). Methods:With ELISA, we determined the levels of sIL-2R of 48 patients with ALL after their first diagnoses,complete remission 1 and relapse. The levels of sIL-2R of 30 patients from complete remission 1 to relapse were monitored. Results: The levels of sIL-2R were higher in the relapse group and first diagnosed group than in the control. The levels of sIL-2R were higher in the relapse group and first diagnosed group than in the complete remission 1 group. However,the difference between the complete remission 1 and the control had no statistical significance. When we determined the levels of sIL-2R dynamically, we found that after complete remission ,the levels of sIL-2R decreased,however, before one month of hematological relapse, the levels of sIL-2R increased. Conclusion: Monitor of the level of sIL-2R can predict impending relapse of patients with ALL and is helpful to early diagnosis of relapse.

Objective To evaluate the clinical outcome of autologous hemopoietic stem cell transplantation (AHSCT) for hematological malignancies. Methods Data of 61 patients with hematological malignancies who underwent AHSCT in Xiangya Hospital from April 1994 to August 2008 were retrospectively analyzed. There were 30 acute non-lymphoblastic leukemias (ANLL), 25 non-Hodgkin lymphoma (NHL), 3 Hodgkin lymphoma (HL), and 3 plasmacytoma. Mel 160 mg/m2 + Ara-C 2.0/2.5 g × 2 +Cy 1.8 g/m2 × 2, or TBI 8-10 Gy + Cy 1.8 g/m2 × 2 were mainly included in pretreatment regimens. Results All patients had rapid hemopoietic reconstitution. There was one patient who died of heart failure during the transplantation process. The rate of AHSCT related death was 1.6 %. The median follow up duration was 52(2-211) months. Forty-seven of 61 patients were still alive during the analysis. The probabilities of disease free survival (DFS) at 5 years were significantly different between these two groups: (77.5±5.5) % for AHSCT groups and (31.6±7.3) % for synchronous intensive chemotherapy groups(P ＜0.01). Conclusion AHSCT can be safely performed as an important treatment constituent for hematological malignancies.

OBJECTIVE: To study the efficacy of allogeneic hemotopoietic stem cell transplantation (allo-HSCT) for hematological malignancy. METHODS: A total of 104 patients with hematological malignancy, who underwent allo-HSCT in Xiangya Hospital from December 1999 to January 2010, were retrospectively analyzed. Of the patients, the transplantation related mortality (TRM), relapse rate (RR), 5-year overall survival (OS) and disease free survival (DFS) were estimated by Kaplan-Meier analysis. The unfavorable prognostic factors were also statistically examined. RESULTS: Hematopoietic reconstitution was achieved in 101 patients. At the last data of follow-up, the incidences of severe acute graft versus host disease (aGVHD) and extensive chronic GVHD were 15.38% and 25.53%, and the TRM and RR were 15.66% and 21.76%, respectively. The estimated 5-year OS and DFS for all patients were (73.49±4.59)% and (63.10±5.32)%, respectively. Those for acute myeloid leukemia (AML) patients were (63.00±9.51)% and (49.30±9.96)%, and those for chronic myeloid leukemia (CML) patients were (83.87±5.06)% and (74.55±6.79)%, respectively. The survival analysis suggested the poor prognostic factors for allo-HSCT recipients including female sex, severe aGVHD and refractory hematological malignancy. Further multivariate analyses revealed that severe aGVHD and refractory hematological malignancy were the independent risk factors of poor prognosis for the recipients (P<0.05). The 5-year DFS of severe aGVHD and refractory hematological malignancy patients was (48.22±12.69)% and (42.09±12.31)%, respectively. The TRM of severe aGVHD, HLA-mismatched graft and unrelated donor transplant was significantly higher than that of the corresponding control groups (57.14% vs. 4.81%, 33.33% vs. 10.41%, 26.09% vs. 9.28%; P<0.05). The RR of refractory hematological malignancy was significantly higher than that of the control group (41.09% vs. 15.63%, P<0.05). CONCLUSION The treatment of allo-HSCT can improve the disease free survival of patients with hematological malignany and is an important therapeutic method for hematological malignancy. Severe aGVHD and refractory hematological malignancy are the independent risk factors of poor prognosis for the allo-HSCT recipients with hematological malignancy.

In the clinical settings, disseminated intravascular coagulation (DIC) and complications such as hemorrhage are commonly seen in acute promyelocytic leukemia patients, whereas thrombosis is rarely reported. We reported a case here that the patient presented with cerebral infarction as the first manifestation. During the admission, the patient encountered differentiation syndrome, pulmonary embolism, pulmonary hemorrhage, and myocardial ischemia, as well as bleeding and thrombosis complications. Hence the patient was diagnosed as DIC. After the treatment of blood transfusion instead of anticoagulation, his condition was stable and the remission was completely achieved. The treatment experience provides guides for other patients with similar complications of simultaneous bleeding and thrombosis.
