| seroprevalence of helicobacter pylori infection in urban and rural vietnam. | helicobacter pylori-associated diseases, such as peptic ulcer and gastric cancer, are common in vietnam, but the prevalence of the infection is largely unknown. a validated enzyme-linked immunosorbent assay was used for seroepidemiology with 971 samples from the general population, ages 0 to 88 years, with 546 samples from an urban population (hanoi), and with 425 samples from a poor, rural province (hatay). the overall seroprevalence of the infection was 746 per 1,000, with a prevalence of 788 ... | 2005 | 15642989 |
| analysis of virulence factors of helicobacter pylori isolated from a vietnamese population. | the incidence of gastric cancer differs among countries in asia, and it has been suggested that virulence factors associated with helicobacter pylori are partly responsible. the aim of this study was to investigate several genetic factors regarded as virulence or molecular epidemiologic markers in h. pylori isolates from vietnamese subjects. | 2009 | 19698173 |
| helicobacter pylori infection and gastroduodenal diseases in vietnam: a cross-sectional, hospital-based study. | the rate of h. pylori infection in vietnam is reportedly high, but the spectrum of h. pylori-associated gastroduodenal diseases has not been systematically investigated. moreover, despite the similarities of ethnicity and diet, the age-standardized incidence rate of gastric cancer in the northern city of hanoi is higher than that in the southern city of ho chi minh, but the reason for this phenomenon is unknown. the virulence of vietnamese h. pylori has also not been investigated in detail. | 2010 | 20920280 |
