A knowledge of the bacterial ecology of a haematology unit should help in the management of the febrile patient with or without neutropenia. We studied the prevalence and the susceptibility profiles of bacteria isolated during a six-year period among patients hospitalized in a 44-bed haematology unit. Antibiotic use over this period was also studied. The(More)
BACKGROUND Paroxysmal nocturnal haemoglobinuria (PNH) is a rare acquired disorder of haematopoietic stem cells. Although knowledge about the pathophysiology of the disease is increasing, no multivariate analysis of factors influencing survival has been undertaken, mainly because the disease is rare. We undertook such an investigation. METHODS Data were(More)
PURPOSE To describe the main characteristics and outcome of adult's acquired immune hemolytic anemias (AIHA). To analyse the relevance of the complementary tests performed for the search of an underlying disease. METHODS Retrospective (1980-2000) monocentric study. INCLUSION CRITERIA age above 16, AIHA defined by an hemoglobin level below 12 g/dl in men(More)
Ten adult patients with warm antibody haemolytic anaemia at initial presentation and seven other patients with either refractory AIHA (two patients) or who relapsed after an initial response to prednisone (five patients) were treated with both Danazol and prednisone. 80% of the first group, but also 60% of the second group displayed long-lasting responses(More)
A new case of a defect in red cell pyrimidine 5′-nucleotidase (P5N) activity was found in a large family from Guadeloupe in the West Indies. The propositus presented a characteristic hemolytic anemia with red cell basophilic stippling, an increased GSH level, and a shift of the peak in absorbance of nucleotide. The enzyme activity of the deficient red cells(More)
Magnetic resonance (MR) imaging is a method of choice for assessing vascular patency and parenchymal iron overload. During the course of paroxysmal nocturnal hemoglobinuria (PNH), it is clinically relevant to differentiate abdominal vein thrombosis from hemolytic attacks. Furthermore, the study of the parenchymal MR signal intensity adds informations about(More)
In a series of 40 patients with Budd-Chiari syndrome, 5 (12%) were found to be afflicted with paroxysmal nocturnal hemoglobinuria. The clinico-pathological features in these 5 patients and in 26 well-documented previously reported cases could be ascribed to three groups of increasing severity: thrombosis limited to small-sized hepatic veins with no or(More)
This study defines the risk of central nervous system (CNS) relapse in patients undergoing bone marrow transplantation (BMT) for acute lymphoblastic leukemia (ALL) in remission, with no posttransplant prophylactic CNS therapy. Ninety-two consecutive patients in complete remission received BMT for ALL (n = 82) or high-grade non-Hodgkin's lymphoma with poor(More)
In two patients a peripheral neuropathy was the presenting symptom of a noncutaneous peripheral T-cell lymphoma. In the first patient, the neuropathy had a relapsing and remitting course, the symptoms improved under corticosteroid therapy. The second patient suffered from a relentless neuropathy. In both cases the lymphoma infiltrated the peroneal nerve(More)
We prospectively assessed autologous stem cell transplantation for consolidation treatment in a trial of intensive chemotherapy in high risk myelodysplastic syndromes (MDS). In this trial, patients aged 55 years or less with no HLA-identical sibling and achieving CR were scheduled to receive unmanipulated autologous bone marrow transplantation (ABMT)(More)
