Abacwaningi e-Duke University Cancer Institute bathole ukuthi i-H. pylori ingase ibangele ingozi eyengeziwe yomdlavuza we-colorectal, ikakhulukazi kubantu abanombala. Abantu abanebala elimhlophe basemathubeni amaningi okuthi batholwe futhi babulawe umdlavuza wesikhumba.
Abaphenyi baphinde bahlola ukuxhumana phakathi kukaH. Pylori nomdlavuza obala ngamangqamuzana. More than half of the world’s population is infected with Helicobacter pylori, bacteria can cause gastric cancer and gastric ulcers. Researchers at Duke University collected samples from subjects of different races and checked antibody levels before cancer developed. Half of the more than 8,000 study participants continue to develop colorectal cancer. To determine whether the presence of antibodies increased the likelihood of developing colorectal cancer, the researchers compared the frequency of antibodies between cancer and non-cancer subjects. They observed similar rates of past infections in the two groups. As a result, a higher percentage of black and Latino subjects had H. pylori antibodies. This finding is consistent in both cancer and non-cancer tissues. Antibodies specific for Helicobacter pylori proteins are most commonly found in different ethnic groups. Most importantly, a high-level antibody to the H. pylori protein-VacA protein is closely related to the incidence of colorectal cancer in African-American and Asian Americans.
Ukuhlangana phakathi kwe-H. pylori nomdlavuza we-colorectal kudlala indima kubantu abanombala futhi kungathinta kakhulu izinketho zokwelapha, izinhlelo zesenzo, kanye nokwehluka kwezempilo yomphakathi okuhlobene nomdlavuza. Ochwepheshe bezokwelapha bangakwazi ukukhomba abantu abasengozini enkulu abanomdlavuza we-colorectal ngokusekelwe esimweni se-Helicobacter pylori futhi banciphise izinga lomdlavuza ngokwelashwa.
