| occult hepatitis b virus infection in a north american adult hemodialysis patient population. | hepatitis b virus (hbv) infections continue to occur in adult hemodialysis units. a possible contributing factor is the presence of occult hbv (serum hepatitis b surface antigen [hbsag] negative but hbv dna positive). two hundred forty-one adult hemodialysis patients were screened for occult hbv. hbv dna testing was performed by real-time polymerase chain reaction (pcr) with 2 independent primer sets (core promoter and surface). two (0.8%) of the 241 patients were hbsag positive. of the remainin ... | 2004 | 15486926 |
| hepatitis b immunization in a low-incidence province of canada: comparing alternative strategies. | this study provides a comparative cost-effectiveness analysis of three universal immunization programs for hepatitis b virus (hbv). using three theoretical cohorts of infants, 10-year-olds, and 12-year-olds, a universal immunization program was compared with a prenatal screening/newborn immunization program involving testing of prepartum women and immunization of newborns of hbsag-positive mothers. a markov long-term outcome model used manitoba data to estimate costs and health outcomes across t ... | 1997 | 9343806 |
| the risks of transmission of acute hepatitis a and b virus infection in an urban centre. | in a large urban centre of a developed nation, 63 household contacts of 20 index cases with acute hepatitis a virus infection and 95 household contacts of 29 index cases with acute hepatitis b virus infection were prospectively followed for 2 years to document the risk of acquiring acute hepatitis from the index case. twenty-one of 63 (33%) hepatitis a virus household contacts had serologic evidence of previous hepatitis a virus infection on the initial serum sample. of the remaining 42 suscepti ... | 1994 | 7963411 |
| epidemiological study of hepatitis b virus infection in manitoba, canada, 1992-2003. | in comparison with other canadian provinces and most western countries, the province of manitoba maintains a different vaccination policy for hepatitis b. this policy provides selective antenatal screening for hepatitis b in women and an inoculation program for hepatitis b vaccination for fourth-grade pupils. there has been increasing concern for this policy with regard to its influence on secular trends of acute hepatitis b incidence in manitoba. this created a need to summarise the epidemiolog ... | 2005 | 15959814 |
| antibody to hepatitis d virus (delta agent) in selected manitoba residents, 1974-1986. | the prevalence of antibody to hepatitis d virus (hdv) was determined in serum samples collected from 174 manitoba residents between 1974 and 1986. anti-delta was detected in five of 123 hbv-infected individuals for an overall prevalence of 4.1%. three of 54 (5.5%) persons who were sampled in the period 1974-77 were anti-delta positive, as were two of 69 (2.9%) sampled between 1982 and 1986 (p greater than 0.05). four of 31 (12.9%) acute hepatitis b patients, and one of 92 (1.1%) chronic hbsag ca ... | 1988 | 3135966 |
