| hepatitis e virus infection in patients from saudi arabia with sickle cell anaemia and beta-thalassemia major: possible transmission by blood transfusion. | the seroprevalence of antibodies against hepatitis e virus (hev) and hepatitis c virus (hcv) was investigated in saudi children with sickle cell anaemia (sca) (50 patients: 28 boys, 22 girls; age range 2-14 years) and beta-thalassemia major (28 patients: 12 boys, 16 girls; age range 2-12 years). the sca patients were from the gizan area (south) while the thalassemics were from the riyadh area (central province). the prevalence of hepatitis e virus antibody (hevab) in patients with sca (18.0%) an ... | 1996 | 8871882 |
| profile of hepatitis c virus and the possible modes of transmission of the virus in the gizan area of saudi arabia: a community-based study. | the seroprevalence of antibody to hepatitis c virus (anti-hcv) and the possible modes of transmission of hcv were investigated in gizan, southern saudi arabia. the sample size chosen to give an adequate estimate of the seroprevalence, about 1500, was based on the assumption that 5% of the population in gizan were anti-hcv-positive. sera from 1482 subjects (705 males, 777 females; aged > or = 10 years) were initially screened for anti-hcv using a commercial, ubiquitin-based enzyme immunoassay. re ... | 1995 | 7487230 |
| prevalence of antibody to hepatitis c virus among saudi arabian children: a community-based study. | in a population-based survey, 39 (0.90%) of 4,496 saudi arabian children (ages 1 to 10) were positive for antibody to hepatitis c virus. no significant difference was seen between the prevalence rate in males (0.9%) and females (0.8%) or between urban (0.7%) and rural dwellers (1.0%). a significant variation of rates (0% to 5.7%) was seen from one region to another. the gizan population, noted for hyperendemic hepatitis b virus infection, had the highest prevalence of antibody to hepatitis c vir ... | 1991 | 1650324 |
| the decline of hepatitis b viral infection in south-western saudi arabia. | hepatitis b virus (hbv) infection is endemic in the kingdom of saudi arabia (ksa). the jizan region in the south-western area of the country was noted for a high prevalence of hepatitis b surface antigen (hbsag) carrier rate. the study was carried out to determine the prevalence of hbsag and other markers of hbv among residents of jizan and evaluate the impact of the measures adopted in the last decade, to control hbv. | 2003 | 12973485 |
