| seroprevalence of immunoglobulin g, m, and a antibodies to helicobacter pylori in an unselected danish population. | the seroprevalences of increased levels of immunoglobulin g (lgg), m (lgm), and a (lga) antibodies to helicobacter pylori were assessed by enzyme-linked immunosorbent assay techniques in 3,589 danes who participated in a population study in copenhagen county in 1982. a total of 33.9% of the study population had one or more classes of increased antibodies to h. pylori. increased levels of lgg, lgm, and lga antibodies to h. pylori were seen in 25.9% (95% confidence interval (cl) 24.5-27.3), 4.5% ( ... | 1996 | 8633606 |
| primary gastrointestinal non-hodgkin's lymphoma in adults: a population-based clinical and histopathologic study. | to analyse the clinical course and the histopathology of primary gastrointestinal non-hodgkin's lymphoma (gi-nhl) in adult patients and to investigate a possible impact of helicobacter pylori. | 1998 | 9698027 |
| [genetic markers for stomach ulcer. a study of 3,387 men aged 54-74 years from the copenhagen male study]. | knowledge on the genetic risk of peptic ulcer has predominantly been based on hospital materials. to minimize selection bias, we tested the association between some genetic markers and the risk of peptic ulcer in a large-scale epidemiologic design. | 1998 | 9739607 |
| genetic and life-style determinants of peptic ulcer. a study of 3387 men aged 54 to 74 years: the copenhagen male study. | in the copenhagen male study men with the lewis blood group phenotype le(a+b-), non-secretors of abh antigen, and men with the o or the a phenotype in the abo blood group have been found to have a significantly higher lifetime prevalence of peptic ulcer than others. we investigated the importance of the association of these genetic markers, life-style factors, and social class with lifetime risk of peptic ulcer, testing specifically the hypothesis that the strength of the association of risk fac ... | 1999 | 10048726 |
| seroconversion and seroreversion in igg antibodies to helicobacter pylori: a serology based prospective cohort study. | to assess the incidence of seroconversion and seroreversion in igg antibodies to helicobacter pylori within a 11 year observation period using these events as markers for acquisition and loss of the infection, respectively. | 2000 | 10818120 |
| indigenous greenlanders have a higher sero-prevalence of igg antibodies to helicobacter pylori than danes. | to assess the sero-prevalence of igg antibodies to helicobacter pylori (h. pylori) in greenlanders and compare with the sero-prevalence in caucasian danes. | 2003 | 12725341 |
| does helicobacter pylori infection explain all socio-economic differences in peptic ulcer incidence? genetic and psychosocial markers for incident peptic ulcer disease in a large cohort of danish adults. | peptic ulcer epidemiology has changed considerably within the past century. the aim of this study was to assess the 11-year cumulative incidence of peptic ulcer disease and examine the relationship between ulcer incidence and psychosocial and genetic factors. | 2004 | 15513379 |
