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'

Nephrotic syndrome has been described as one of the clinical forms of chronic graft-versus-host disease (cGVHD), but a limited number of cases have been described. We experienced a young female patient with nephrotic syndrome developed 22 months after allogeneic hematopoietic stem cell transplantation (HSCT) for severe aplastic anemia. She had been well after successful management for gut-limited cGVHD until she developed a clinical nephrotic syndrome with hypoalbuminemia of 2.0 g/dL and 24-hr urine protein of 6.88 g/dL. On physical examination and laboratory findings, there was no other evidence of cGVHD. Clinical and renal biopsy findings were consistent with cGVHD-related membranous nephropathy, and immunosuppressive agents with cyclosporine and prednisone were prescribed. After 3 month of treatment, the proteinuria decreased to normal range; and the patient from nephrotic syndrome nearly recovered. We recommend cGVHD-related glomerulonephritis should be considered in all patients with hypoalbuminemia following allogeneic HSCT, even if there is no other evidence of clinical GVHD.

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.

8.Cardiac Surgery in a Patient with Idiopathic Aplastic Anemia: A Case Report.
Journal of Korean Medical Science 2007;22(5):912-913
Major surgery in a patient with pancytopenia might be associated with increased surgical risks, especially for bleeding and infection. A 66-yr-old man was admitted to the hospital due to shortness of breath. His dyspnea was classified by the New York Heart Association (NYHA) as functional class III. Prior to admission, he had a 5-yr history of medical management for idiopathic aplastic anemia. The severity of aplastic anemia of the patient was graded as non-severe aplastic anemia. Echocardiography revealed reduced left ventricular function and severe aortic valve regurgitation (grade IV) with left ventricular end diastolic dimension measuring 87 mm. Because of dyspnea and echocardiographically documented aortic valve insufficiency, the patient underwent elective aortic valve replacement. Although extracorporeal circulation for valve operations might be associated with aggravation of impaired blood cell function, the patient recovered from surgery uneventfully. Here, we report a successful cardiac surgery with extracorporeal cardiopulmonary bypass in a patient with severe aortic valve insufficiency and concomitant idiopathic aplastic anemia.

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.

10.Complete Hematopoietic Recovery after Continuous Iron Chelation Therapy in a Patient with Severe Aplastic Anemia with Secondary Hemochromatosis.
Journal of Korean Medical Science 2008;23(2):320-323
A 16-yr-old male patient with hemochromatosis due to multiple packed red blood cell transfusions was referred to our emergency center for the treatment of severe aplastic anemia and dyspnea. He was diagnosed with aplastic anemia at 11-yr of age. He had received continuous transfusions because an HLA-matched marrow donor was unavailable. Following a continuous, approximately 5-yr transfusion, he was noted to develop hemochromatosis. He had a dilated cardiomyopathy and required diuretics and digitalis, multiple endocrine and liver dysfunction, generalized bleeding, and skin pigmentation. A total volume of red blood cell transfusion before deferoxamine therapy was about 96,000 mL. He received a regular iron chelation therapy (continuous intravenous infusion of deferoxamine, 50 mg/kg/day for 5 days q 3-4 weeks) for approximately seven years after the onset of multiple organ failures. His cytopenia and organ dysfunctions began to be gradually recovered since about 2002, following a 4-yr deferoxamine treatment. He showed completely normal ranges of peripheral blood cell counts, heart size, and liver function two years ago. He has not received any transfusions for the last four years. This finding suggests that a continuous deferoxamine infusion may play a role in the immune regulation in addition to iron chelation effect.
