| parvovirus b19 induced red cell aplasia in myelofibrosis. | a 38-year-old female presented with moderate anaemia and a leucoerythroblastic blood film. subsequent investigation showed myelofibrosis in cellular phase. her haemoglobin quickly and spontaneously recovered with concurrent serological evidence of recent parvovirus b19 infection. this is the first report in the literature of parvovirus causing red cell aplasia in myelofibrosis. | 1993 | 8136287 |
| parvovirus b19-related lymphadenopathy. | we tested whether parvovirus b19 (pvb19) is involved in benign lymph node swelling as a causative agent. the serum specimens from 13 patients with lymph node swelling of unidentified cause were tested for igm and igg antibody against pvb19 by western blot analysis. five patients had igm antibody, and pvb19 dna was detected in the serum from one of them by dot-blot analysis, suggesting the recent pvb19 infection and its involvement in lymph node swelling of these patients. clinical and haematolog ... | 1993 | 8136290 |

| papular-purpuric 'gloves and socks' syndrome: not only parvovirus b19. | we previously described an acute dermatosis characterized by pruritic erythematous and slightly papular lesions on the hands and feet in a 'gloves and socks' distribution associated with oral aphthoid lesions and fever (papular-purpuric 'gloves and socks' syndrome = ppgss). we strongly suspected a viral origin, but serologic tests for a large panel of viruses remained negative. subsequently, 2 cases of ppgss with serologic evidence of a parvovirus b19 infection have been reported in the literatu ... | 1994 | 8136553 |
| resistance to parvovirus b19 infection due to lack of virus receptor (erythrocyte p antigen). | the presence of a specific cellular receptor is thought to be necessary for susceptibility to viral infection. the erythrocyte p antigen is the cellular receptor for parvovirus b19. we hypothesized that the rare persons with the p phenotype, whose erythrocytes do not have this receptor, would be naturally resistant to b19 infection, which causes erythema infectiosum. | 1994 | 8139629 |

| microplate capture hybridization of amplified parvovirus b19 dna fragment labelled with digoxigenin. | a capture hybridization technique in microplate has been developed for the identification of polymerase chain reaction (pcr) amplified b19 dna fragment in clinical specimens. the amplified 104 bp b19 dna fragment, located in the gene coding for structural proteins, was directly labelled during the amplification reaction by incorporation of digoxigenin-labelled dutp. the amplified product was then captured by a probe immobilized on microplate wells. the capture hybridization reaction was visualiz ... | 1993 | 8145776 |
