1/19. MRI findings of muscle involvement in idiopathic hypereosinophilic syndrome.A 40-year-old white man presented with fever, muscle pain, skin nodules and persistent hypereosinophilia over a period of 1 year. In addition, he had ventricular arrhythmias with episodes of tachycardia. Besides a lack of response to antiparasitic therapy, laboratory and pathological data excluded the diagnosis of trichinosis or any other parasitic infection. The patient's course of the disease over the previous 1(1)/2 years was compatible with hypereosinophilic syndrome. In a muscle biopsy several eosinophilic perivascular and leucocytic intravascular infiltrates were found, indicative of muscle involvement by the disease. This is a report on the MRI findings of muscle involvement in idiopathic hypereosinophilic syndrome.- - - - - - - - - - ranking = 1keywords = white (Clic here for more details about this article) |
2/19. Allogeneic peripheral blood cell transplantation for hypereosinophilic syndrome with myelofibrosis.patients with hypereosinophilic syndrome (HES) display a very heterogeneous clinical picture ranging from asymptomatic cases to very aggressive forms. We report a 38-year-old woman with progressive HES who developed severe myelofibrosis and was treated by allogeneic stem cell transplantation, using peripheral blood (PBSCT) instead of bone marrow as the source of progenitor cells, after conditioning with cytoxan and busulphan. To the best of our knowledge, this is the first case of HES with myelofibrosis treated with PBSCT. The patient remains alive 8 months post-PBSCT, and bone marrow fibrosis has significantly decreased following transplantation. bone marrow transplantation (2000) 25, 217-218.- - - - - - - - - - ranking = 111.29071504097keywords = blood cell (Clic here for more details about this article) |
3/19. Complete haematological and cytogenetic response to interferon alpha-2a of a myeloproliferative disorder with eosinophilia associated with a unique t(4;7) aberration.A female patient with eosinophilia and cardiac symptoms was found to have a unique chromosomal aberration [t(4;7)(q11;p13)] of bone-marrow precursors. The disorder was classified as a chronic myeloproliferative syndrome with eosinophilia. Due to a significant increase in the white blood cell and eosinophil count during initial treatment with prednisone and hydroxyurea, Interferon alpha-2a was administered at a dose of 3-5 x 10(6) I.U. s.c., five times per week, and induced a long-term complete haematological and cytogenetic response. The clinical features of this case are presented and discussed in the context of the current literature.- - - - - - - - - - ranking = 166.21379180604keywords = white blood cell, white blood, blood cell, white (Clic here for more details about this article) |
4/19. Recurrent cholestasis and hypereosinophilia in a young female.A 22-year-old female presented, in December 1998, with asthenia, itching and hypereosinophilia. In January 1997, due to the same clinical picture, the patient had inappropriately been diagnosed elsewhere to have an "idiopathic eosinophilic syndrome" and complete remission was obtained after short-term steroid treatment. Upon admission, physical examination was negative and blood tests revealed absolute eosinophilia [42%, i.e., 3,800 of 9,600 white blood cells], aspartate aminotransferase 4 x upper limits of normal, alanine aminotransferase 5 x upper limits of normal and alkaline phosphatase 2 x upper limits of normal. Both liver biopsy and endoscopic retrograde cholangiopancreatography findings were totally consistent with primary sclerosing cholangitis, while all known causes of hypereosinophilia and alteration in liver function tests were carefully excluded. The clinical course was characterized by complete clinical and biochemical normalization in absence of any treatment and further follow-up was completely negative.- - - - - - - - - - ranking = 166.21379180604keywords = white blood cell, white blood, blood cell, white (Clic here for more details about this article) |
5/19. Chronic eosinophilic leukaemia presenting with erythroderma, mild eosinophilia and hyper-IgE: clinical, immunological and cytogenetic features and therapeutic approach. A case report.A 23-year-old, white male metallurgist presented with pruritic erythematous maculo-papules over the trunk and upper limbs and 6 months later developed erythroderma, eosinophilia and multi-organ dysfunction. A diagnosis of chronic eosinophilic leukaemia was made on the basis of myeloproliferative involvement of both peripheral blood and bone marrow, associated with eosinophilic differentiation and a t(5;12)(q33;p13) translocation. The initial therapeutic approach was interferon alfa-2b plus cytosine arabinoside, for 13 months, followed by hydroxyurea plus vincristine. There was improvement of skin lesions, disappearance of eosinophilia and decrease of serum immunoglobulin e, towards normal values.- - - - - - - - - - ranking = 1keywords = white (Clic here for more details about this article) |
6/19. Childhood idiopathic hypereosinophilic syndrome: report of a case.We described a 15-year-old girl who presented with persistent fever, bilateral flank pain, and worsening dyspnea. The peripheral blood cell count showed remarkable eosinophilia at the time of admission. Severe pleural effusion with eosinophilic Infiltrations as well as pericardial effusion were noted thereafter. bone marrow examination disclosed markedly increased eosinophils. Bilateral ectasia of the renal pelvis was found in an ultrasonographic study of the kidneys. Spiking fever and progressive shortness of breath persisted despite treatment with empiric antibiotics for infection. Based on the clinical course and histological findings, a tentative diagnosis of idiopathic HES was made. After treatment with oral prednisolone daily (1 mg/kg/day) for one week, there was a rapid improvement in her clinical condition. She was discharged a few days later and the steroids were withdrawn gradually when she was asymptomatic. The absolute eosinophil count (AEC) was monitored during follow-up. At 3 weeks, the AEC had fallen from 8,060/mm3 to 4,792/mm3 and it further fell to 1,591/mm3 at 5 months, and to 855/mm3 at 8 months during follow-up. There is no evidence of any other organ involvement until now. The clinical manifestations, diagnosis and management of idiopathic HES in children are also reviewed.- - - - - - - - - - ranking = 27.822678760243keywords = blood cell (Clic here for more details about this article) |
7/19. Periodic oscillation of blood leukocytes, platelets, and hemoglobin in a patient with chronic eosinophilic leukemia.Chronic eosinophilic leukemia (CEL) is a rare myeloproliferative disease in which autonomous, clonal proliferation of eosinophilic precursors results in persistent increase of eosinophils in the blood and bone marrow. A case of CEL spontaneous oscillation of white blood cell (WBC) count is presented. The cycle of WBC variation comprised about 60 days. Similar cyclic variations were noted in his platelet count, hemoglobin level and bone marrow cellularity, as well as in the spleen size, which was directly correlated with the WBC count. The numbers of bone marrow erythroid colony-forming units (CFU-E), granulocyte-macrophage colony-forming units (CFU-GM) and the serum level of colony-stimulating factors (CSFs) were also regularly changed during the oscillation of WBC. Bone marrow hyperplasia was accompanied with the increase in peripheral WBC count, suggesting that the variation of cell production caused the cyclic oscillation.- - - - - - - - - - ranking = 166.21379180604keywords = white blood cell, white blood, blood cell, white (Clic here for more details about this article) |
8/19. Loffler's endocarditis associated with unusual ECG change mimicking posterior myocardial infarction.A73-year-old man with a history of bronchial asthma and atrial fibrillation was admitted to our hospital because of dyspnea and back pain. Blood analysis revealed a marked increase in total blood cell and eosinophil counts. The creatine kinase and creatine kinase-MB increased slightly. The ECG demonstrated significant ST-segment depression that mimicked acute posterior myocardial infarction. Emergent coronary angiography showed no stenotic lesions. The histological findings in endomyocardial biopsy showed thickened endocardium associated with significant eosinophilic infiltration, which was compatible with Loffler's endocarditis. After the administration of prednisolone, the patient's general condition, eosinophilia, ECG abnormalities, and histological findings were improved dramatically. The endomyocardial biopsy in the acute phase was helpful for diagnosis and therapeutic decision-making.- - - - - - - - - - ranking = 27.822678760243keywords = blood cell (Clic here for more details about this article) |
9/19. Eosinophilic pericarditis: a rare complication of idiopathic hypereosinophilic syndrome in a child.We describe an 18-month-old child with idiopathic hypereosinophilic syndrome (IHES) who presented with fever, and cervical lymphadenopathy. Chest X-ray showed marked cardiomegaly, and echocardiogram revealed large pericardial effusion. Other causes of pericarditis were excluded. Despite the initiation of steroid therapy, signs of impending cardiac tamponade developed. pericardiocentesis yielded bloody fluid with a white blood count of 14,800/mm3, of which 23% were eosinophils. The child recovered after pericardial drainage and prolonged systemic steroid therapy. Eosinophilic pericarditis is a rare but potentially dangerous complication of IHES.- - - - - - - - - - ranking = 47.017446753952keywords = white blood, white (Clic here for more details about this article) |
10/19. hypereosinophilic syndrome and cyclic oscillations in blood cell counts. A clonal disorder of hematopoiesis originating in a pluripotent stem cell.We studied a patient with hypereosinophilic syndrome (HES) who had myeloproliferative features, was unresponsive to imatinib mesylate, and showed cyclic oscillations in blood cell counts. No rearrangement in PDGFRA, PDGFRB and ETV6 genes was detected. Clonal analysis of hematopoiesis consistently showed skewed X-chromosome inactivation patterns in both granulocytes and t-lymphocytes, indicating a clonal myeloproliferative disorder originating in a pluripotent stem cell.- - - - - - - - - - ranking = 139.11339380122keywords = blood cell (Clic here for more details about this article) |
