1/38. Complete remission of refractory anemia following a single high dose of cyclophosphamide.We describe a case of stable complete remission in a patient with refractory anemia complicated by severe autoimmune hemolytic anemia, achieved with a single high dose (4 g/m2) of cyclophosphamide (cyclo). Concomitantly, an effective mobilization of CD34-positive cells was induced. Other immunosuppressive approaches including high-dose methylprednisolone, high-dose immunoglobulin, and cyclosporine had been ineffective. This finding suggests that, in selected cases, an immunologic mechanism may mediate cytopenia in myelodysplastic syndromes (MDS). In addition, it demonstrates that successful mobilization of peripheral blood stem cells can be induced with high-dose cyclo in MDS.- - - - - - - - - - ranking = 1keywords = hemolytic (Clic here for more details about this article) |
2/38. Relapsing polychondritis and myelodysplasia: a report of two cases and review of the current literature.Relapsing polychondritis (RP) is a rare multisystem disorder. We describe two case reports of patients with RP, one of whom developed myelodysplasia subtype refractory anaemia (RA) and the other, refractory anaemia with ringed sideroblasts (RARS). We also review the literature of association between RP and haematological disorders.- - - - - - - - - - ranking = 208.80654326742keywords = anaemia (Clic here for more details about this article) |
3/38. Co-existence of cutaneous true histiocytic lymphoma with refractory anaemia: report of a case.The case of a 70-year-old man with refractory anaemia who developed cutaneous true histiocytic lymphoma two years after diagnosis, is described. Whether this association is a simple coincidence or indicates some etiopathogenetic relationship between these two unrelated disorders is unknown and needs the analysis of more cases.- - - - - - - - - - ranking = 522.01635816856keywords = anaemia (Clic here for more details about this article) |
4/38. Novel association of haemophagocytic syndrome with Kaposi's sarcoma-associated herpesvirus-related primary effusion lymphoma.Haemophagocytic syndrome (HPS) is a fulminant, often fatal, systemic illness that occurs in association with infection and malignancy. We provide the first report of HPS that heralded a primary effusion lymphoma (PEL), a rare neoplasm linked to Kaposi's sarcoma-associated herpesvirus. The patient was a 38-year-old man with acquired immunodeficiency syndrome who presented with fever, sweats, lymphadenopathy, splenomegaly and refractory anaemia. Examination of the spleen demonstrated haemophagocytosis; analysis of ascites revealed PEL. Treatment with chemotherapy and ganciclovir resulted in complete remission of both conditions. This case illustrates the diagnostic challenges posed by HPS and supports the trial of antiviral agents in combination with chemotherapy in patients with PEL.- - - - - - - - - - ranking = 104.40327163371keywords = anaemia (Clic here for more details about this article) |
5/38. Autologous peripheral blood stem cell transplantation and anti-B-cell directed immunotherapy for refractory auto-immune haemolytic anaemia.We report the clinical course of a 6.5-year-old boy with refractory auto-immune haemolytic anaemia. Due to failure of conventional immunosuppressive therapy, an autologous peripheral blood stem cell transplantation was performed. The conditioning regimen consisted of cyclophosphamide and anti-thymocyte globulin. The patient was reinfused with 2.6 x 10(6) CD34 positive selected, B- and T-cell-depleted peripheral blood stem cells per kg body weight. He showed a partial response with a reduced demand for red blood cell transfusions. However, due to persistence of the haemolytic process he was started on rituximab therapy on day 40 post-transplant. Following two doses of rituximab, the patient improved rapidly and developed a sustained complete response. After 10 months, haemolysis recurred and responded again to rituximab therapy without the necessity for red blood cell transfusions. 15 months after initial antibody treatment, however, the patient developed a second relapse which was now refractory to rituximab therapy although CD20 b-lymphocytes were cleared from the peripheral blood. CONCLUSION: Our case report suggests that rituximab and autologous peripheral blood stem cell transplantation are important though not curative elements in the treatment of patients with severe auto-immune haemolytic anaemia who are refractory to conventional immunosuppressive therapy.- - - - - - - - - - ranking = 626.41962980227keywords = anaemia (Clic here for more details about this article) |
6/38. gastric antral vascular ectasia--a cause of refractory anaemia in systemic sclerosis.Recurrent gastrointestinal haemorrhage is an uncommon manifestation of systemic sclerosis. We report a case of gastrointestinal bleeding due to gastric antral vascular ectasia (GAVE) in a patient with systemic sclerosis. Failure to recognise the condition as a cause of gastrointestinal bleeding may delay the instigation of appropriate treatment. GAVE should be considered in the differential diagnosis of anaemia in patients with autoimmune conditions such as systemic sclerosis and primary biliary cirrhosis.- - - - - - - - - - ranking = 522.01635816856keywords = anaemia (Clic here for more details about this article) |
7/38. Secondary acute myeloid leukaemia with monosomy 7 in identical adult twins.We report the development of secondary acute myeloid leukaemia (AML) with monosomy 7 in identical twins, both at the age of 52 years. In the first twin, induction therapy resulted in complete remission (CR). At relapse 9 months later monosomy 7 was found. The patient died of sepsis 11 months after diagnosis. The other twin presented with leucopenia and thrombocytopenia and refractory anaemia (RA) was diagnosed. During follow-up, fluorescence in situ hybridization analysis demonstrated a monosomy 7 in 11% of the cells. Twenty-eight months following diagnosis the patient progressed to RA with excess blasts in transformation and induction chemotherapy was initiated without achieving CR. Three months later an allogeneic stem cell transplantation from a niece was performed, resulting in CR of the secondary AML.- - - - - - - - - - ranking = 104.40327163371keywords = anaemia (Clic here for more details about this article) |
8/38. Successful treatment of refractory autoimmune haemolytic anaemia in a post-unrelated bone marrow transplant paediatric patient with rituximab.Here, we report a case of paediatric beta-thalassaemia major patient who underwent unrelated T cell-non- depleted bone marrow transplantation and developed a complication of autoimmune haemolytic anaemia (AIHA) refractory to corticosteroid and intravenous immunoglobulin therapy. After this child received two doses (375 mg/m2/dose) of rituximab (anti-CD20 monoclonal antibody), his AIHA was resolved.- - - - - - - - - - ranking = 522.01635816856keywords = anaemia (Clic here for more details about this article) |
9/38. Myelodysplastic syndrome complicated by autoimmune hemolytic anemia: remission of refractory anemia following mycophenolate mofetil.Autoimmune hemolytic anemia (AIHA) rarely occurs in myelodysplastic syndrome (MDS). A 36-year-old Asian female was diagnosed with MDS (refractory cytopenia with multilineage dysplasia, RCMD) and complicated by AIHA 7 months later. Secondary myelofibrosis developed at the same time. Steroid therapy was ineffective and cyclosporin A (CsA) was discontinued due to its neurotoxicity with the development of leukoencephalopathy. However, the patient achieved a good hematological response after the use of mycophenolate mofetil (MMF, CellCept) with a dose of 1 g/day and prednisolone (15 mg/day). Prednisolone was tapered off over the next 3 weeks. The patient did not require any blood support 4 weeks after the use of MMF and has been hematologically stable for 4 months. To our knowledge, this is the first report of using MMF in treating MDS complicated by AIHA. MMF might be considered as a salvage therapy for patients with refractory anemia complicated by AIHA.- - - - - - - - - - ranking = 5keywords = hemolytic (Clic here for more details about this article) |
10/38. Protein 4.1 deficiency and deletion of chromosome 20q are associated with acquired elliptocytosis in myelodysplastic syndrome.We report a case of myelodysplastic syndrome (MDS), associated with prominent elliptocytosis. A 66-year-old male presented with peripheral pancytopenia, and was diagnosed with MDS [refractory anaemia (RA)]. Apart from marked elliptocytosis, dyshaematopoietic features were not evident in his peripheral blood or hypercellular bone marrow. After 18 months, he had progressed to RA with excess blasts in transformation. Analysis of red blood cell membrane proteins by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) showed a reduced quantity of protein 4.1 (30% of control). Deletion of chromosome 20q was identified by conventional cytogenetic analysis and fluorescence in situ hybridization. Marked elliptocytosis, persistent for more than 17 months, decreased strikingly after chemotherapy with idarubicin and Ara-C. These findings suggest that acquired elliptocytosis occurred as an unusual morphological feature of MDS, associated with abnormalities of protein 4.1 and chromosome 20q.- - - - - - - - - - ranking = 104.40327163371keywords = anaemia (Clic here for more details about this article) |
