The combination of melphalan-prednisone-thalidomide (MPT) has been investigated in several clinical studies that differed significantly with regard to patient characteristics and treatment schedules. This prospective trial differs from previous melphalan-prednisone (MP) vs. MPT trials by treatment dosing, duration, routine anticoagulation, and permission(More)
This study was designed to measure the effect of iron supplementation on antioxidant status in iron-deficient anemia, including the time for hemoglobin normalization and at the time of filling of iron body stores. The extent of plasma lipid peroxidation was evaluated by measuring the levels of malondialdehyde and glutathione peroxidase (GSH-Px), and the(More)
Posttransplant lymphoproliferative disorder (PTLD) is a serious complication of organ transplantation, with a reported incidence between 0.8% and 32%. The incidence of PTLD mainly depends on the transplanted organ, the immunosuppressive drugs, the viral serology, and the age of the recipient. The aim of our study was to analyze our patients diagnosed with(More)
We describe a 52-year-old woman with pancytopenia associated with Sheehan's syndrome, whose presenting feature was severe malaise and syncope after a psychological stress. Hormonal replacement therapy alone (with L-thyroxine and prednisolone) produced clinical and full haematological recovery. This is a very rare case of Sheehan's syndrome because the(More)
OBJECTIVE To investigate the plasma antigenic levels and functional activities of coagulation inhibitors in poorly controlled diabetic patients and the possible effect of good glycemic control on these parameters. RESEARCH DESIGN AND METHODS Both functional activities and plasma antigenic levels of coagulation inhibitors (antithrombin III, heparin(More)
The haemophagocytic syndrome (HS) is an uncommon reactive proliferation of mature histiocytes, and is more frequently but not exclusively associated with infections in individuals with pre-existing immunologic abnormalities. As far as we know, only 13 cases of tuberculosis-associated HS have previously been reported. We present here two cases of(More)
This study was designed to measure the effects of iron supplementation on respiratory burst in iron-deficient anemia. The performance of neutrophils was evaluated by measuring the activity of NADPH oxidase in 18 patients with iron-deficient anemia before and after body iron stores are saturated. The activity of NADPH oxidase was significantly lower in(More)
Acute coronary events are more likely to occur in the morning and it has recently been shown that platelet aggregability increases significantly then. To determine whether circulating platelet aggregates show such a circadian variation, we measured in vivo platelet aggregation in atherosclerotic patients and healthy subjects at three-hour intervals(More)
Several reports have shown that granulocyte colony-stimulating factor (G-CSF) administration induces a transient, mild hypercoagulable state, which might predispose certain donors to thrombotic complications. In the present study, changes in the expression of neutrophil adhesion molecules (CD11b/CD18, CD62L) and platelet-neutrophil complex formation(More)
There have only been a few reports of bilateral hip fractures resulting from hypocalcaemic convulsions. We report a case of simultaneous bilateral fractures of the femoral neck and superior pubic ramus caused by convulsions secondary to renal failure-induced hypocalcaemia. To our knowledge, such an occurrence has not previously been described.
