We have retrospectively analyzed a series of 19 patients with hepatitis C virus (HCV) infection and chronic thrombocytopenia not attributable to hypersplenism or to other causes. Antiplatelet antibodies were present in 81% of cases. Response to prednisone was observed in 6 of 7 patients and 1 of 3 patients responded to intravenous immunoglobulins. No case(More)
Several studies have shown the presence of fibroblast-like cells in the stromal fraction of different tissues with a high proliferative and differentiation potential. Platelet alpha granules contain growth factors released into the environment during activation. The effects of different supplements for culture medium (human serum, bovine serum and platelet(More)
OBJECTIVE Abacavir and didanosine are nucleoside reverse transcriptase inhibitors (NRTI) widely used in therapy for HIV-infection but which have been linked to cardiovascular complications. The objective of this study was to analyze the effects of clinically relevant doses of abacavir and didanosine on human leukocyte-endothelium interactions and to compare(More)
OBJECTIVES The main limitation factor for the wide use of umbilical cord blood (UCB) as a source of hematopoietic progenitor for transplantation is cell dose. One of the specific areas identified by some studies for improvement of UCB collection is donor selection. METHODS Over a 3-mth period, 391 consecutive maternal-neonatal pairs were evaluated during(More)
BACKGROUND Volume reduction is a widely used procedure in umbilical cord blood banking. It concentrates progenitor cells by reducing plasma and red blood cells, thereby optimising the use of storage space. Sepax and AXP are automated systems specifically developed for umbilical cord blood processing. These systems basically consist of a bag processing set(More)
BACKGROUND The reference values for total serum IgE are accepted to vary according to the geographical area involved. In 1981 we published the reference values for a donor population in the city of Valencia (Spain) and its metropolitan area. Since then, we have noted an increase in the prevalence of asthma and rhinitis in countries with a Western lifestyle,(More)
Blood plasma levels of ochratoxin A, a toxic secondary metabolite of several fungal species belonging to the genera Aspergillus and Penicillium, were determined in 168 blood donors from the population of Valencia (Spain) using LC-FLD. In conjunction with blood collection, detailed information on diet was obtained by using a questionnaire that encompassed a(More)
BACKGROUND AIMS Volume reduction is the usual process in cord blood banking that has some advantages regarding reducing the storage space and dimethyl sulfoxide (DMSO) quantity in the final product. The volume reduction methodology must guarantee high cell recovery and red blood cell (RBC) depletion by reducing all the umbilical cord blood (UCB) units to a(More)
BACKGROUND Umbilical cord blood (UCB) banking is a well-established activity supporting the increasing number of UCB transplantations in haematological diseases. Our aim was to analyse the UCB characteristics of UCB units from preterm deliveries and compare them to full-term deliveries. MATERIAL AND METHODS A prospective study in 194 preterm deliveries(More)
