| aids studies in japan. | the aids surveillance system in japan was set up in 1984 and by 1987, 29 aids patients had been reported. 10 were homosexuals, 16 were hemophiliacs and 3 were heterosexuals. 9 out of 16 hemophiliacs with aids had a-type hemophilia. 2 females were also reported as victims of aids. 19 patients have died 5 male homosexuals (4.4%) out of 113 (93 japanese and 20 foreigners) individuals were anti-hiv-positive. in 1984 sera from 65 hemophiliacs, 85 hemodialysis patients and 304 healthy volunteer b ... | 1987 | 3112053 |
| factors predisposing to htlv-1 infection in residents of the greater tokyo area. | human t-cell leukemia virus type 1 (htlv-1) is the etiological agent for adult t-cell leukemia. the geographic distribution of htlv-1 carriers is quite uneven in japan and the greatest prevalence is in southwestern japan. because many people move from endemic areas to the greater tokyo area, the geographic distribution might have changed. therefore, we investigated the factors predisposing to htlv-1 infection, including birthplace, for 88 htlv-1-infected individuals in greater tokyo who visited ... | 2008 | 19034610 |
| anti-htlv-iii and anti-htlv-i antibodies and t cell subsets in hemophiliacs living in htlv-i endemic and nonendemic areas of japan. | sera from 154 hemophiliacs, including 132 with hemophilia a and 22 with hemophilia b, were examined for antibodies against human t cell lymphotropic virus type iii (htlv-iii) and type i by strip radioimmunoassay based on the western blotting technique. sixty-two patients lived in kyushu, a known endemic area of htlv-i and 92 patients lived in tokyo, a nonendemic area of htlv-i. results showed a prevalence of htlv-iii antibodies of 64.5% in kyushu and of 57.6% in tokyo. there were no significant ... | 1987 | 2883800 |
| cutaneous lymphomas in tokyo: analysis of 62 cases in a dermatology clinic. | the epidemiology of cutaneous lymphomas revealed that the incidence of lymphomas differed depending on various factors including area, race, and sex, among others. | 2001 | 11277951 |
| a multicenter case-control study of htlv-i associated uveitis. study group for htlv-i associated ocular diseases. | to elucidate the epidemiology of human t-lymphotropic virus type i (htlv-i) associated uveitis (hau), a multicenter case-control study was carried out by the collaboration of university hospitals throughout kyushu and okinawa in southwestern japan where htlv-i is endemic; two institutions in the non-endemic metropolitan areas of tokyo and yokohama also participated. a total of 426 cases of endogenous uveitis were registered during the five-month period between september 1992 and january 1993; th ... | 1994 | 7967207 |
| discrepancy between human t-cell lymphotropic virus type i screening test and confirmatory tests in non-endemic areas. | the purpose of this study was to examine the seroprevalence of human t-lymphotropic virus (htlv)-i among pregnant women at our institution in tokyo, japan, which is a non-endemic area, and to investigate the results of western blotting among pregnant women who had obtained positive results from a screening test. | 2012 | 22414005 |
| epidemiology of uveitis, caused by htlv-1, toxoplasmosis, and tuberculosis; the three leading causes of endemic infectious uveitis in japan. | ethnicity, geography, and socioeconomic factors are among the aspects influencing the prevalence of uveitis in specific areas and countries. human t-lymphotropic virus type 1-associated uveitis and ocular toxoplasmosis are endemic to southern kyushu, the southern-most region of japan. recent reports have postulated that the prevalence of intraocular tuberculosis is increasing in tokyo. this review focuses on local factors that affect the three major vectors for infectious endemic uveitis in japa ... | 2016 | 27925851 |
| current prevalence of htlv-1 in japan as determined by screening of blood donors. | human t-cell leukemia virus type-1 (htlv-1), a major source of adult t-cell leukemia and related diseases, is endemic to southwestern japan. mother-to-infant transmission via breast milk is an important route of infection, and establishing programs to prevent such transmission requires exact figures on the htlv-1 prevalence rate and the number of carriers. therefore, the seroprevalence of htlv-1 among 1,196,321 japanese first-time blood donors from 2006 to 2007 was investigated. a total of 3,787 ... | 2012 | 22170555 |
| malignant lymphomas in japanese aids patients. | seven non-hodgkin's malignant lymphomas (mls) were found in 25 japanese aids (acquired immune deficiency syndrome) patients who died at two hospitals in tokyo. all of these mls originated from extranodal organs including the brain (three cases), skin (two cases) liver and adrenal gland. b cell markers were demonstrated in all of them. epstein-barr virus (ebv) capsid antigen (ebvca) was demonstrated in 5/7, nuclear antigen (ebna) in 2/2, the w fragment of ebv dna by in situ hybridization in 5/7 a ... | 1991 | 1667449 |
| antibodies to human immuno-deficiency virus and human t-cell leukemia virus type i in japanese patients with hematologic malignancies. | one thousand six hundred and seventy-four blood samples drawn between january 1980 and april 1986 from 1454 japanese, including 251 leukemia, 409 lymphoma, 76 adult t-cell leukemia and 25 benign lymphadenitis patients, were tested for antibodies to hiv and htlv-i. no patient with lymphadenitis or lymphoma associated with hiv infection was found. in 87 patients with acute and chronic leukemias who had received multiple transfusions, 8 were positive for anti-htlv-i antibody after blood transfusion ... | 1986 | 2880831 |
| prevalence of htlv-1 antibodies in hemodialysis patients in japan. | the southwestern region of japan is known as a very high endemic area of human t-cell lymphotropic virus type 1 (htlv-1), the etiologic agent for adult t-cell leukemia (atl) and probable causative agent for tropical spastic paraparesis and its japanese version, htlv-1-associated myelopathy (ham). hemodialysis (hd) patients seem to be at high risk for htlv-1 infection even in other regions of japan because they sometimes receive multiple blood transfusions. we examined antibody against atl-associ ... | 1988 | 2901222 |
