OBJECTIVE Viruses are considered possible aetiologic agents of autoimmune disease. Evidence suggests that human cytomegalovirus (HCMV) may be a pathogenetic factor in systemic lupus erythematosus (SLE). We undertook a seroepidemiological study to determine whether HCMV infection is increased in patients with SLE. METHODS Sero-epidemiologic data,(More)
Glycoprotein gp52 exists within the mature human cytomegalovirus (HCMV) envelope in heterodimeric, disulphide-linked complexes with glycoproteins gp95 and gp130. Biochemical studies involving immunoprecipitations and Western blots have demonstrated that gp52 is the glycoprotein B (gB) homologue of HCMV but that gp95 and gp130 are probably separate gene(More)
BACKGROUND Multicomponent apheresis is an alternative way of preparing blood components that avoids the delay between collection and separation seen with standard whole-blood techniques. STUDY DESIGN AND METHODS An apheresis device has been modified to facilitate the combined collection of a unit (250 mL) of red cells (RBCs) and a high-volume unit (475(More)
We evaluated whole blood integral filtration to produce leucocyte-depleted red cells and plasma by using the WBF1 whole blood filter (Pall Medsep). Whole blood units were filtered after either warm (2-4 h at room temperature) or cold (12-24 h at 4 degrees C) holds. Filtered and control units were processed using either a bottom-and-top or top-top method.(More)
Various techniques for detecting bacteria in blood products exist; however, none has been widely accepted. Our method permits direct bacterial detection in both platelet concentrates (PC) and packed red blood cells (RBC). This novel procedure targets bacterial ribosomal RNA (rRNA) but does not utilize culture or nucleic acid amplification. The assay(More)
Transfusion-transmitted bacterial infections cause significant patient morbidity and mortality. This study aimed to improve the sensitivity of a nucleic acid-based electrochemiluminescence (ECL) assay for pretransfusion bacterial testing of cellular blood components. The approach is dependent on the detection of bacterial 16S ribosomal RNA (rRNA). The(More)
Residual donor leucocytes are responsible for many adverse transfusion reactions. Prestorage leucodepletion may ameliorate these effects and enhance product quality. We studied a bottom and top (BAT) system incorporating an integral filter for whole blood leucodepletion. Our evaluation assessed leucodepletion efficiency as well as in vitro SAG-M red cell(More)
Donor leucocytes are responsible for many adverse transfusion effects. Clinical reactions may be attributed to specific leucocyte subsets. In this study leucocyte subpopulations were identified and quantified pre- and post-leucodepletion by integral filtration using novel Optipac(R) configurations incorporating either WBF-1 (Pall Medsep) or RS2000 (Asahi)(More)
Cytomegalovirus (CMV) is a double-stranded DNA virus which can be transmitted by blood transfusion. Its seroprevalence in adults ranges from 40% to 100% depending on geographical and socioeconomic conditions. Seropositive individuals have latent CMV infection with viral DNA present in peripheral blood leucocytes. CMV can be associated with considerable(More)
