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'

OBJECTIVETo investigate the clinical features and therapeutic method for severe aplastic anemia (SAA) associated with β-thalassemia, and to improve the recognition of the disease.

METHODSOne patient hospitalized for pancytopenia was reported and the related literatures were reviewed.

RESULTSA 14-years old girl who presented with anemia from her childhood was hospitalized for acute onset of pancytopenia. Routine blood test showed that WBC count was 1.28×10⁹/L, hemoglobin 65 g/L, platelet count 18×10⁹/L, reticulocyte count 2×10⁹/L, neutrophil count 0.03×10⁹/L and mean corpuscular volume 59.6 fl, respectively. Both bone marrow aspiration and biopsy showed hypoplasia. Her red blood cells presented as microcytic hypochromic and target erythrocytes were common on peripheral blood smear. DNA analysis of the patient and her mother showed exon 17 heterozygous β-thalassemia (c.52 A>T). A diagnosis of SAA associated with β-thalassemia was clarified and high-dose cyclophosphamide (HD-CTX, 1.2 g/d×4 d) plus cyclosporine were offeved, which eventually led to a complete hematologic remission 12 months later.

CONCLUSIONThis was the first report of SAA associated with β-thalassemia, and the regimen of HD-CTX led to a complete hematologic remission.

Herein is presented a case of aplastic anemia associated with adenocarcinoma of the stomach which seem- ed to be coincidental. A 52 year-old man was admitted with a 3 year history of dyspnea. Three years previously, he was diagnosed as bone marrow hypoplasia and had been treated with oxymetholone for 1 year. After confirmation of aplastic anemia during the first admission, he was followed up with fluoxymesterone and steriods. One year later, he was readmitted with melena. Fibergastroscopy and an UGl study revealed a fungating mass on the antrum suggestive of stomach cancer. Following perioperative platelet transfusions and intensive supportive care, a subtotal gastrectomy was performed and there were no postoperative complications. Pathologic examinations disclosed a moderately well differentiated adenocarcinoma. This is the first report in Korea of adenocarcinoma of the stomach occurring in a patient with aplastic anemia. He survived 17.5 months after the surgery and 5.4 years after the onset of aplastic anemia. Gastrointestinal bleeding in aplastic anemia may be incorrectly ascribed to steriod use and overlooked, thus the need to fully investigate gastric pathology by endoscopy as well as radiology is streesed. In a patient with pancytopenia, the major surgical procedures are frequently evaded by both surgeons and internists due to the possibility of morbidity from bleeding and infection. In this case, intensive perioperative supportive care and surgery were combined to prolong the patient's survival time.

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.

The pathogenic mechanism of focal segmental glomerulosclerosis (FSGS) and aplastic anemia are associated with immunologic events which lead to glomerular cell injury or hematopoietic cell destruction. We present an extremely rare case of FSGS with aplastic anemia in a 30-yr-old woman. The laboratory examination show-ed hemoglobin 7.2 g/dL, white blood count of 4,200/microliter, platelet count 70,900/microliter. Proteinuria (2+, 3.6 g/day) and microscopic hematuria were detected in urinalysis. The diagnosis of FSGS and aplastic anemia were confirmed by renal and bone marrow biopsy. She was treated with immunosuppressive therapy of prednisone 60 mg/day orally for 8 weeks and cyclosporine A 15 mg/kg/day orally. She responded with gradually improving her clinical manifestation and increasing peripheral blood cell counts. Prednisone was maintained at the adequate doses with tapering after 8 weeks and cyclosporine was given to achieve trough serum levels of 100-200 ng/mL. At review ten month after diagnosis and initial therapy, the patient was feeling well and her blood cell counts increased to near normal (Hb 9.5 g/dL, Hct 32%, WBC 8,300/microliter, platelet 123,000/microliter) and renal function maintains stable with normal range proteinuria (0.25 g/day).

OBJECTIVETo study the clinical features of severe aplastic anemia (SAA) patients with complication of infection.

METHODSA retrospective analysis of prevalence of infection occurring in 229 SAA patients, their bacterial spectrum, and the effect of GM-CSF or G-CSF on the infection were done.

RESULTThe prevalence of infection in SAA patients was 86.0%, among which 54.2% was infected with gram-positive organisms, 40.0% with gram-negative bacilli and 5.8% with fungal infections. Septicemia occurred mostly with E. coli and Pseudomonas infection. Patient's neutropenia was significantly related to the infection. The patients with neutrophil count less than 0.2 x 10(9)/L had more frequent and severe infection. Age, hemoglobin level, subtype of T lymphocytes and antithymocyte globulin therapy were not related to infection. Prophylaxis usage of floxacin could not reduce patient' gastrointestinal infection. The total mortality of SAA patients with infection was 23.1%. Pulmonary infection and septicemia increased mortality, and GM-CSF/G-CSF therapy reduce mortality.

CONCLUSIONSAA patients were at high risk of infection which was significantly associated with severe neutropenia. GM-CSF or G-CSF therapy exerts an assistant role to antibiotics in controlling the infections.

Epstein-Barr virus (EBV) causes various acute and chronic diseases. Chronic active EBV infection (CAEBV) is characterized by infectious mononucleosis-like symptoms that persist for more than 6 months with high viral loads in peripheral blood and/or an unusual pattern of anti-EBV antibodies. Severe CAEBV is associated with poor prognosis with severe symptoms, an extremely high EBV-related antibody titer, and hematologic complications that often include hemophagocytic lymphohistiocytosis. However, CAEBV which led to the development of aplastic anemia (AA) has not been reported yet. A 73-year-old woman was admitted to our hospital with intermittent fever, general weakness and elevated liver enzymes. In the serologic test, EBV-related antibody titer was elevated, and real-time quantitative-PCR in peripheral blood showed viral loads exceeding 10(4) copies/microg DNA. Liver biopsy showed characteristic histopathological changes of EBV hepatitis and in situ hybridization with EBV-encoded RNA-1 was positive for EBV. Pancytopenia was detected in peripheral blood, and the bone marrow aspiration biopsy showed hypocellularity with replacement by adipocytes. AA progressed and the patient was treated with prednisolone but deceased 8 months after the diagnosis due to multiple organ failure and opportunistic infection. Herein, we report a rare case of severe CAEBV in an adult patient accompanied by AA and persistent hepatitis.
