Human polyomavirus BK (BKV) and JC (JCV) infections were examined in persons infected with human immunodeficiency virus type 1 (HIV-1). High frequencies of BKV (24%) and JCV viruria (16%) were detected by polymerase chain reaction (PCR). BKV viruria was not found in an immunocompetent control group, in contrast to a frequency of JCV viruria of 20%. The(More)
The chemiluminescence (CL) was examined when peripheral blood monocytes were incubated with opsonized Neisseria meningitidis, serogroup B, serotype 15:P1.16 or serotype 2a:P1.2. The monocytes were separated from a mononuclear cell suspension by an immunomagnetic negative selection technique using magnetic polystyrene microspheres coated with monoclonal(More)
Patients with autoimmune chronic active hepatitis (AICAH) and certain other chronic liver disorders often have very high titres of haemagglutination-inhibition (HI) antibodies to rubella virus. In this study it is shown, using floatation centrifugation, that the high rubella HI reactivity is not caused by nonspecific lipoprotein inhibitors but rather by(More)
We have developed a standardized procedure for the isolation of monocytes from peripheral blood by negative selection using magnetic polymer particles coated with monoclonal antibodies against T and B lymphocytes. The average purity of the monocyte suspension was 85%, and monocyte recovery was 72% from Ficoll-Hypaque gradient separated mononuclear cells and(More)
Cytomegalovirus (CMV) antibody profiles were studied in 25 HIV-infected patients over periods of up to 56 months. Specific antibodies against CMV antigen components were monitored by complement-fixation (CF) test, EIA, Western blot and a neutralization assay. Three subjects remained CMV seronegative throughout the study. Marked fluctuations were observed in(More)
Incubation of polymorphonuclear leukocytes (PMNs) in fusidic acid resulted in a decrease of random migration and chemiluminescence. The effects were dose-dependent but moderate, with statistical significance only at concentrations of 50 mg/l or more. At concentrations used for therapy of bacterial infections and AIDS, fusidic acid was not shown to be(More)
Sera from 298 HIV-infected individuals from Southern Norway were examined for antibodies against HTLV. 30 sera (10.1%) were HTLV-II positive and 1(0.3%) HTLV-I positive. 25 of the HTLV-II infected subjects were intravenous drug abusers (IVDAs), giving a prevalence of HTLV-II infection of 24.5% in this group. Examination of blood samples by polymerase chain(More)
Isoprinosine may delay disease progression in human immunodeficiency virus infection, presumably through modulation of lymphocyte function. However, the influence of isoprinosine on phagocyte function is largely unknown. This study describes the effects of isoprinosine and azidothymidine on phagocyte chemiluminescence and migration. Incubation with(More)
In an investigation in spring 1989 on research training at the Medical Faculty, University of Bergen, 111 questionnaires were returned of a total of 180 distributed. 35% of the trainees were satisfied with the training, 31% not, while 30% did not know as yet. Trainees who had been full-time research fellows for two years or more (n = 33), were split in two(More)
Streptococcus pneumoniae is a common cause of morbidity and mortality in children, immunodeficient individuals and elderly people. As antibiotic resistant strains become more prevalent, pneumococcal infections will become more difficult to manage. Pneumococcal vaccination is inexpensive, and serious side effects are rare. However, the efficacy and safety of(More)
