| human t cell leukemia virus type 1 (htlv-1) antibodies in healthy populations and renal transplanted patients in the north-east of brazil. | the seroprevalence of human t cell leukemia virus type 1 (htlv-1) infection was investigated in brazilians (570): native inhabitants (298) and descendants from japanese (272) living in recife and its neighborhoods--north-east of brazil. furthermore, polytransfused renal transplanted patients (54) were also examined for the serological status to this virus. the seropositivity to htlv-1, screened by enzyme-linked immunosorbent assay (elisa), was low: 1.34% for the local population and 0.73% for th ... | 1994 | 7968679 |
| no relationship between htlv-1 infection and filariasis--serological study on patients with filariasis in recife, brazil. | the seroprevalence of antibodies against human t-cell leukemia virus was determined by elisa in 68 patients with filarial infestation living in an endemic area. the total seropositivity was 2.9% and the htlv-1-positive cases were detected in 2 microfilaremic patients 12 and 40 years old. this value is very close to that obtained for healthy individuals in the same region and age groups. this result suggests that there is no relationship between filariasis and htlv-1 infection as previously propo ... | 1995 | 8657021 |
| [infection and disease caused by the human t cell lymphotropic viruses type i and ii in brazil]. | htlv-i/ii infection is present in all regions of brazil, but its prevalence varies according to the geographical area, being higher in bahia, pernambuco and pará. it has been estimated that brazil has the highest absolute number of infected individuals in the world. blood donors screening and research conducted with special groups (indigenous population of brazil, iv drug users and pregnant women) are the major sources of information about these viruses in our country. htlv-i causes adult t cell ... | 2002 | 12621671 |
| geographic diversity of adult t-cell leukemia/lymphoma in brazil. the brazilian atll study group. | we describe 195 cases of adult t-cell leukemia/lymphoma (atll) reported to the national registry of t-cell malignancies in brazil between 1994 and 1998. we compared the effect of demographic differences and clinical features of 150 consecutive atll cases in different regions of this diverse country. at diagnosis, the predominant clinical sub-type was the acute type (60%), followed by lymphoma (22%), chronic (10%) and smoldering (8%) types. although we expected that different sub-types would be p ... | 1999 | 10495418 |
| cytomegalovirus, human herpesvirus 6 and human t cell leukemia virus infection in renal transplanted patients in the northeast of brazil. | the seroprevalence of antibodies against cytomegalovirus (cmv), human herpesvirus 6 (hhv-6) and human t cell leukemia virus type 1 (htlv-1), determined by elisa and by fluorescence in 54 renal transplanted patients, was 96.2%, 88.8% and 11.1%, respectively. these values are relatively high when compared with the results obtained for healthy individuals of the same age groups from recife, northeastern brazil. active cmv infection was detected by the presence of igm antibodies and/or virus isolati ... | 1993 | 8268822 |
