We present the results of tests carried out to detect alloimmunization against red cells in 1,200 patients (607 males and 593 females), transfused and followed up during the period 1981-1987 in our hospital. Of these patients, 1,135 were thalassemic and 65 had sickle cell/beta-thalassemia. In 162 patients who received blood matched for the AB0, rhesus and(More)
The prevalence and risk factors of hepatitis A, B, and C (HAV, HBV, and HCV) markers were compared in non-Roma and Roma children who lived in a deprived suburb of Athens, Greece. The study included 216 children, 118 Roma and 98 non-Roma of 9 years median age (range 5-15 years). Among Roma children 98.3% had detectable antibodies to HAV, compared with 32.7%(More)
Transfusional iron overload leading to cardiopathy and other severe complications continues to be a major problem in chronically transfused homozygous beta-thalassaemia patients. It is well known that young red cells (neocytes) survive longer after transfusion and therefore may contribute to the extension of the intervals between transfusions. We evaluated(More)
A study has been carried out on the incidence of non-hemolytic transfusion reaction on a group of patients suffering from thalassemia. Of this group, the rate of reactions per patient, based on the relationship between the number of patients with non-hemolytic transfusion reactions and the total number had risen to 31.8%. 83.7% of the patients with(More)
Sister-chromatid exchange (SCE) frequencies were determined in human peripheral blood CD4+ and CD8+ T lymphocyte subpopulations which were rapidly and highly purified from pooled T lymphocytes by immunological methods. The purified lymphocytes were stimulated with phytohemagglutinin (PHA) for 4 days. CD4+ lymphocytes showed significantly higher SCE(More)
The aim of our study was to measure the concentrations of Fibronectin in LBW neonates during infections, as well as the correlation of blood levels with immunoglobulin administration. Fibronectin (FN) levels were measured from the serum of 16 premature neonates BW=1150±260gr and GA= 29±2w. Samples were taken weekly from the 30th week of gestational age(More)
