T cell subpopulations, defined by monoclonal antibodies (OKT3, OKT4 and OKT8), were assessed on 13 patients with myelodysplasia (MDS). The percentage and numbers of OKT3- and OKT4-positive lymphocytes were significantly lower (p less than 0.025) than in normal controls, whereas those of OKT8 were not. In the group of patients with refractory anemia with(More)
In order to evaluate fetal erythropoiesis we measured red blood cells, hemoglobin, hematocrit, serum transferrin receptor (sTfR), and iron status parameters in fetuses undergoing percutaneous umbilical blood sampling, and in normal newborns at term. We found high levels of sTfR in fetuses and newborns as compared with normal adults (3,149 +/- 181 vs. 1,881(More)
Anaphylatoxins generated by complement activation by filter membranes are present in plasma during hemodialysis (HD). In the presence of endotoxins which may contaminate the dialysate, they can trigger monocytes to produce interleukin-1 (IL-1) and tumor necrosis factor (TNF), with detrimental effects for the patients. We have investigated whether or not the(More)
