| markers of health status in an htlv-i-positive cohort. | the health effects of chronic human t-cell lymphotropic virus type i (htlv-i) infection were examined in a cohort of japanese men who had emigrated from okinawa, japan, and had been participants in a prospective study in hawaii since 1965. in the present follow-up study carried out in 1987-1988, various health indicators were measured in the subjects, whose mean age was 72.5 years. participation rates were lower in the htlv-i seropositives than in the seronegatives (46.7% vs. 76.0%) in the > or ... | 1992 | 1488961 |
| declining seroprevalence and transmission of htlv-i in japanese families who immigrated to hawaii. | this study examined the seroprevalence and transmission of human t cell lymphotropic virus type i (htlv-i) in japanese families who originated in okinawa, an area in which htlv-i is endemic, and who were currently residing in hawaii, a nonendemic area. among a cohort of japanese men whose sera were collected in hawaii in 1967-1975, those of okinawan ancestry had an htlv-i seroprevalence of 11.4%. this study, conducted in 1987-1988, sampled 142 index subjects from this male cohort and tested them ... | 1991 | 1951296 |
| incidence of antibodies against human immunodeficiency virus, human t-cell lymphotropic virus type 1, hepatitis b virus, hemorrhagic fever with renal syndrome virus and chlamydia in tonga and western samoa. | among the populations of tonga and western samoa, serum antibodies against human immunodeficiency virus or hemorrhagic fever with renal syndrome virus were not detected (0/904 and 0/192). no serum samples were considered to be positive for antibody against human t-cell lymphotropic virus type 1 (0/527). hepatitis b antigen and antibody were found in 4% (8/192) and 47% (90/192), respectively. chlamydia trachomatis igg and c. psittaci igg antibodies were detected in 39% (75/192) and 47% (91/192), ... | 1990 | 2126048 |

| htlv-1, hiv-1, hepatitis b and hepatitis delta in the pacific and south-east asia: a serological survey. | blood samples from 13 locations in the pacific and south-east asia were tested for evidence of infection with human t-cell lymphotropic virus type-1 (htlv-1), human immunodeficiency virus (hiv-1), hepatitis b virus (hbv) and hepatitis delta virus (hdv). no samples were positive for antibody to hiv-1. antibodies to htlv-1 were found in samples from five locations, the maximum prevalence being 19%, in vanuatu. serological markers of hbv infection were found in all locations, the maximal prevalence ... | 1988 | 2892692 |
| retrovirus-associated adult t-cell leukemia-lymphoma: an epidemiologic study of five cases among hawaii-born offspring of migrant japanese. | adult t-cell leukemia-lymphoma (atll) is a distinct clinicopathologic entity etiologically linked to htlv-i infection. we have identified five cases of retrovirus-associated atll among hawaii-born first generation offspring (nisei) of migrant japanese. four patients were offspring of migrant japanese (issei) who emigrated to hawaii from okinawa, an htlv-i endemic area. the fifth patient was born of parents who emigrated to hawaii from fukushima and miyagi prefectures, htlv-i nonendemic areas. ep ... | 1989 | 2921010 |
| modes of transmission and evidence for viral latency from studies of human t-cell lymphotrophic virus type i in japanese migrant populations in hawaii. | human t-cell lymphotrophic virus type i (htlv-i) seroprevalence was 20% among hawaiian japanese migrants (issei) and their offspring (nisei) from okinawa compared to 35% in similarly aged men who were lifetime residents of okinawa. a control group of migrants from a nonendemic area of japan, niigata, had low rates of htlv-i antibodies, suggesting that hawaii per se is not an endemic area for htlv-i. factors that were significantly associated with seropositivity in the okinawa migrant groups were ... | 1986 | 3014518 |
| htlv-i-associated t-cell leukemia in hawaii. | adult t-cell leukemia (atl) is a disease found endemic in southern japan and the caribbean basin. the human t-cell leukemia virus i (htlv-i) has been implicated epidemiologically as the causative agent in this disease. this paper describes the identification of this disease in hawaii in a second generation immigrant from southern japan. the disease was initially indolent, then clinically explosive, characterized by cutaneous lesions, leukemic lymphocytes with convoluted nuclei of t-cell phenotyp ... | 1986 | 2877581 |
| a seroepidemiologic survey of human t-cell lymphotropic virus type i in two hawaiian hematologic-oncologic practices. | a seroepidemiologic survey for antibodies to the human t-cell lymphotropic virus type i (htlv-i) was carried out in two hawaiian hematologic-oncologic practices. specimens of serum or plasma from 215 donors were assayed using the elisa technique, followed by the western blot technique to confirm antibody specificity to htlv-i. of 214 seropositive donors, 16 (7.5%) were positive. of 172 donors of japanese ancestry, 16 (9.3%) were seropositive; none were white, chinese, filipino, or pacific island ... | 1989 | 2735036 |
| human t-cell lymphotropic virus type i (htlv-i) antibodies in pre-diagnostic serum of patients with familial adult t-cell leukemia/lymphoma (atl). | in a study of 7498 american men of japanese ancestry in hawaii, 26 incident cases of leukemia or non-hodgkin's lymphoma were identified after a follow-up period of 19 years. two of the cases, who were brothers, were diagnosed with adult t-cell leukemia/lymphoma (atl). both of these brothers had human t-cell lymphotropic virus type i (htlv-i) antibodies in their stored serum which were obtained 4 and 18 years before diagnosis. none of the 24 patients with other hematologic malignancies or the 26 ... | 1990 | 2373493 |
| seroepidemiological survey of htlv-i infection in french polynesia, cook islands and fiji. | different population groups of french polynesia, cook islands and fiji were screened for human t-lymphotropic virus type i (htlv-i) antibodies. among 1487 individuals sampled in french polynesia, twelve were considered western blot (wb) indeterminate and one was considered wb-positive for htlv-i infection. this positive subject originated from france and was a blood donor. out of 196 polynesians of the cook islands, one was wb-indeterminate. among populations sampled in fiji, one of 222 melanesi ... | 1993 | 8405324 |
| identification and phylogenetic characterization of a human t-cell leukaemia virus type i isolate from a native inhabitant (rapa nui) of easter island. | human t-cell leukaemia virus type i (htlv-i) is endemic in melanesia, one of the three ethnogeographic regions of the pacific; in the other two regions, polynesia and micronesia, the incidence of the virus is relatively low. in an effort to gain new insights into the prevalence of htlv-i in the pacific region, we did a seroepidemiological survey on easter island, which is located on the eastern edge of polynesia. of 138 subjects surveyed, including 108 rapa nui (the native inhabitants of this is ... | 1999 | 10466796 |
| human t-lymphotropic virus type i (htlv-i) and tropical spastic paraparesis or htlv-i-associated myelopathy in hawaii. | tropical spastic paraparesis or human t-lymphotropic virus type i (htlv-i)-associated myelopathy is a degenerative encephalomyelopathy with pyramidal tract dysfunction affecting the lower extremities. it is associated with htlv-i infection and found primarily in the caribbean region and in southwestern japan. five cases of tropical spastic paraparesis (or htlv-i-associated myelopathy) in hawaii are reported. all five patients were born in hawaii; four are women. each of the patients has parents ... | 1990 | 2139754 |
