1.Study complication of aplastic anemia following chemotherapy of acute myelogenous leukemia
Journal of Medical Research 2007;51(4):9-13
Background: Aplastic anemia following chemotherapy of acute leukemia is a common complication, which may lead to severe consequences. Objective: To study characteristics of aplastic anemia occurred in ccute myelogenous leukemia (AML) patients, following chemotherapy. Subjects and methods: A prospective study was carried out in 50 AML patients treated at National Institute of Hematology and Blood Transfusion from Aug 2005 to Dec 2006. These patients were treated by induction chemotherapy with "3+7" regime. Result: Aplastic anemia had been seen in 100% patients. Characteristics of this condition were poor marrow cells (average marrow cell count was 15.1\xb112.6 G/l) and strongly decreased counts of hemoglobin, white blood cells and platelets. Hemoglobin, white blood cell and platelet counts at the lowest level were 83.32 g/l; 0.96 G/l; 30.18 G/l; respectively. This situation prolonged for 3-4 weeks and changed into the most severe condition at the end of second week after chemotherapy. Infection frequency was 92%. Conclusion: Aplastic anemia following chemotherapy of AML patients is a common complication with severe consequences such as significant decrease of WBC and platelet counts, which may lead to opportunistic infection. Hence, this complication must be monitored, detected and treated promptly. \r\n', u'\r\n', u'

Ecthyma gangrenosum is a characteristic skin lesion of systemic infection due to Pseudomonas aeruginosa. It has a high incidence in patients with chronic disease and impaired defense mechanisms. Early diagnosis and appropriate systemic antibiotic therapy is crucial since its mortality rate is very high. We report a case of ecthyma gangrenosum in aplastic anemia.

OBJECTIVETo summarize the clinical features of cytopenia with bone marrow hypoplasia in 100 children and to investigate an effective treatment regimen for myelodysplastic syndrome (MDS) in children.
METHODSA retrospective analysis was performed on the clinical data of 100 children non-randomly selected from Japan and China who were diagnosed with cytopenia with bone marrow hypoplasia between 2006 and 2011. The data of patients from China were subjected to prognostic analysis.
RESULTSThere was no significant difference in the proportion of MDS cases and acquired aplastic anemia (AA) cases between the Japanese and Chinese children. Of the 100 patients, there were 29 cases of acquired AA, 58 cases of refractory cytopenia of childhood (RCC) and 13 cases of refractory cytopenia with multilineage dysplasia (RCMD). There were significant differences in reticulocyte absolute value in peripheral blood and degree of bone marrow proliferation among the three patient groups (P<0.05). The patients from China were followed up for 16-70 months (median, 41 months). After being treated with cyclosporine (CsA) combined with stanozolol, the patients with AA had response rates of 25% and 75%, the patients with RCC had response rates of 47.1% and 82.4%, and the patients with RCMD had response rates of 60% and 60% respectively at 3 and 6 months after treatment.
CONCLUSIONSThere are significant differences in reticulocyte absolute value in peripheral blood and degree of bone marrow proliferation among patients with RCC, RCMD and acquired AA. CsA combined with stanozolol has a good therapeutic efficacy in the treatment of acquired AA and hypoplastic MDS in children, but studies of more cases and a longer follow-up duration are needed.

To compare magnetic resonance (MR) images of the bone marrow (BM) after bone marrow transplantation or immunosuppressive therapy in patients with aplastic anemia (AA), MR imaging of BM was reviewed retrospectively in 16 patients (13 males and 3 females, mean age 26 yr) with AA who completely responded clinically after transplantation or immunosuppressive therapy. The signal intensity (SI) of BM was classified into four patterns according to the increasing amount of cellular marrow, i.e., pattern I to IV. SI of MR imaging of BM exhibited an increase of cellular marrows following both transplantation and immunosuppressive therapy. Of the eight patients on transplantation, the SI of the lumbar spinal BM was pattern III in two patients and IV in six on T1-weighted and short tau inversion recovery (STIR) images. In the eight patients with immunosuppressive therapy, the SI of the lumbar spinal BM was pattern II in one, III in five, and IV in two on T1-weighted images and pattern II in one, III in four, and IV in three on STIR images. SI on MR imaging of the lumbar spinal BM showed a more cellular pattern in patients on transplantation than in those on immunosuppressive therapy.

OBJECTIVETo observe the clinical efficacy of TCM for reinforcing Shen and activating blood circulation to dredge Channels in auxiliary treating chronic aplastic anemia (CAA), and to explore its mechanism.
METHODSSeventy-nine patients with CAA were randomly divided into the treated group treated with TCM plus western medicine and the control group treated with western medicine alone. The clinical efficacy was observed and levels of plasma sFas and sFasL before and after treatment were determined by ELISA.
RESULTSThe basic cure rate and total effective rate in the treated group were 37.50% and 87.50%; while in the control group were 20. 51% and 61.54% respectively. Comparison between the two groups showed significant difference (P < 0.01). The sFas level was markedly lower in both groups before treatment, but after treatment, it got elevated in the treated group significantly (P < 0.05), as compared with that in the control group, the difference was significant (P < 0.01).
CONCLUSIONTCM is effective in treating CAA with less toxic and side-effect, the mechanism might be the inhibition on over apoptosis of hematopoietic cells in CAA patients through regulating immune function of organism.

To evaluate the clinical efficacy of recombinant human Interleukin 11 in the treatment of pre-aplastic anemia, six patients with pre-aplastic anemia were injected with rhIL-11 of 6 million units once a day during 7-14 days. Blood platelet counts were taken on day 8, 15, 30 and 60 after the treatment, and bone marrow examination was performed on day 15 as compared with those before treatment. The results showed that platelet counts in 3 out of 6 patients increased remarkably (50%), one of the six increased moderately (16.7%), another case of the six increased slightly (16.7%), platelet in one out of six did not significantly increase (16.7%), the total efficacy rate is 83.3%, the amount of megakaryocyte in bone marrow of all six patients increased, the side effect of the rhIL-11 treatment was light. In conclusion, the efficacy of recombinant human Interleukin-11 in the treatment of thrombocytopenia patients with pre-aplastic anemia is satisfactory. As the number of the cases is too small to conclude, further exploration needs accumulation of more applications.

To overcome poor graft function after allogeneic bone marrow transplantation (BMT), the use of peripheral blood stem cells (PBSC) instead of bone marrow is gaining more popularity because of its advantages. There may, however, be an increased risk of graft-versus-host-disease (GVHD) because of the large number of lymphocytes present in a leukapheresis product. An 18-year-old man with severe aplastic anemia underwent an allogeneic BMT using his HLA-identical sister. After initial excellent graft take for 8 months, his blood counts gradually decreased to 2.8 x 10(9)/L of white cells and 28 x 10(9)/L of platelets with marrow cellularity of < 10%. After allogeneic granulocyte-colony stimulating factor mobilized PBSC rescue, the patient's blood counts recovered satisfactorily. Around 1 year after the boost, he developed chronic GVHD that responded to prednisolone and cyclosporin A. He is now well on low-dose steroids at day +1055 after PBSC rescue. The present case is the first experience of a long-term follow-up who underwent allogeneic PBSC rescue in Korea.

Aplastic anemia is a rare complication of thymoma and is extremely infrequent after thymectomy. We present a case of a 60-year-old woman with very severe aplastic anemia appearing sixteen months after thymectomy for a thymoma. She underwent thymectomy for a thymoma in April 2000. Preoperative examination revealed no hematologic abnormality. About sixteen months after the operation, she was readmitted because of pancytopenia with cough and fever. Bone marrow aspiration revealed a very severe hypoplasia in all the three cell lines with over 80% fatty tissue, and chest CT revealed no recurrence of thymoma. Her aplastic anemia had responded to cyclosporine A and granulocyte-colony stimulating factor (G-CSF).

OBJECTIVETo investigate the effect of Shenmai injection on chronic aplastic anemia patients and its mechanism.
METHODSixty-five chronic aplastic anemia patients were randomized into treatment group and control group. The patients of the treatment group were treated by injecting Shenmai injection and taking western medicine orally, those of the control group taking western medicine orally only, then the effect was evaluated. The concentration of tumor necrosis factor-alpha (TNF-alpha) in blood serum was detected and the apoptosis of bone marrow CD34+ cell was analysed by DNA ISEL technic before and after treatment.
RESULTThe effective rate of the treatment group and the control group was 63.6 % and 40.6 % respectively, the effect of the Shenmai injection on the treatment group was obviously better than that of the control group (P < 0.01). Before treatment, the concentration of TNF-alpha in blood serum and the apoptosis rate of bone marrow CD34+ cell of the chronic aplastic anemia patient were higher than normal (P < 0.01). After treatment, the concentration of TNF-alpha in blood serum of the treatment group decreased obviously (P < 0.01), and the apoptosis rate of bone marrow CD34+ cell of the treatment group also decreased (P < 0.05), which had significant difference compared with those of the control group (P < 0.05).
CONCLUSIONShenmai injection is efficient to chronic aplastic anemia. The mechanism is decreasing the concentration of TNF-alpha in blood serum and the apoptosis rate of bone marrow CD34+ cell.
