[epidemiological study of hepatitis b and c virus in okinawa and kyushu, japan]. | epidemiological studies of hepatitis b virus (hbv) and hepatitis c virus (hcv) infection in okinawa and kyushu have been conducted since 1970. early in the study period, the prevalence of hbsag on iriomote and hateruma islands in okinawa was 9.0% and 6.1%, respectively, which were significantly higher than the 2.4% in kyushu. prevalence of anti-hbc on iriomote island was 59.8% and that on hateruma island 70.9%, also which were significantly higher than the 30.9% in kyushu. prevalence of hbv infe ... | 1992 | 1331575 |
seroepidemiology of hepatitis c virus infection in hemodialysis patients and the general population in fukuoka and okinawa, japan. | in 1992, a seroepidemiologic study was carried out among hemodialysis patients and the general population in fukuoka and okinawa, japan to determine the presence of hepatitis c virus (hcv) infection and hcv viremia. the markers used were antibody to hcv, determined by second-generation assay (anti-hcv), and hcv rna, determined by the polymerase chain reaction. the prevalence of anti-hcv in fukuoka was 3.3%, 73 per 2237 persons, significantly (p < 0.001) higher than the 0.4%, 5 per 1295, in okina ... | 1994 | 7520320 |
the risk of human t cell leukemia virus and viral hepatitis infection among us marines stationed in okinawa, japan. | the prevalence and incidence of human t cell leukemia virus type i/ii (htlv-i/ii) and hepatitis a, b, and c virus infection were determined among us marines stationed in okinawa, japan. of 2875 personnel, 2 (0.07%) had antibody to htlv-i/ii. after 1-3 years, no htlv seroconversions were observed, although 23% reported sexual contact with okinawans. of 1010 hepatitis-tested marines, 121 (12%) had antibody to hepatitis a virus (anti-hav), 26 (2.6%) had antibody to hepatitis b core antigen (anti-hb ... | 1995 | 7876620 |
clinical features of patients with chronic liver disease associated with hepatitis c virus genotype 1a/i in okinawa, japan. | the clinical characteristics of chronic hepatitis c virus (hcv) carriers with hcv genotype 1a/i infection were investigated and compared with those of chronic hcv carriers infected with 1b/ii, 2a/iii, 2b/iv and the mixed type of infection. we found that 16 of 408 (3.9%) carriers had hcv genotype 1a infection, comprising four of 67 (6.0%) blood donors, 11 of 263 (4.2%) patients with chronic hepatitis and one of 39 (2.6%) patients with liver cirrhosis. three of 408 subjects had a mixed infection o ... | 1997 | 9083921 |
prevalence of liver abnormalities in the general population of okinawa, japan. | a total of 2,825 japanese over 20 years of age living in the yaeyama district of okinawa, japan were investigated in 1983 and 1984 to determine the prevalence and risk factors of liver abnormalities. obesity index, hepatitis b virus markers, hepatitis c virus marker and serum transaminase were measured and the history of alcohol intake was recorded. people with elevated transaminase levels were assumed to have abnormalities of the liver. the overall prevalence of liver abnormalities was 3.6% and ... | 1997 | 9430951 |
high proportion of false positive reactions among donors with anti-hcv antibodies in a low prevalence area. | among 39,656 voluntary blood donors in okinawa prefecture, japan, 115 (0.29%) were repeatedly reactive for antibody to hepatitis c virus (anti-hcv) by second generation (2nd-gen) passive hemagglutination assay (pha). positive serum samples were tested for anti-hcv using three different enzyme immunosorbent assays (elisas; abbott 2nd eia, ubi-hcv-eia, jcc-2) and for hcv-rna by the polymerase chain reaction (pcr). the 115 2nd-gen pha-positive sera were divided into three groups according to the ag ... | 1995 | 7595410 |
