Abstract

Helicobacter pylori(H. pylori) has been associated with the cause of peptic ulcer and gastric cancer. H. pylori infection occur mostly during childhood and increase by aging. In route of transmission, Oral cavity does important role. So we employed this study to elucidate route of transmission by detection of H. pylori in infant saliva. We investigated 20 infants aged below 10 years and 20 teens aged below 20 years as study group and 71 adults aged 20 and over years as control group. H. pylori DNA was isolated from 5(25%) infants aged below 10 years, 6(30%) teens and 17(23.9%) adults by nested polymerase chain reaction(n-PCR). There was no statistically significant difference(P>0.05). The obtained results suggest that H. pylori infection is relatively common in saliva of Korean infant and oral cavity may be reservoir of H. pylori.

Helicobacter pylori(H. pylori)는 위 십이지장 궤양 및 위암의 발생과 관련되어 있으며, 감염은 대부분 유년기에 발생되어 나이가 먹어감에 따라 증가한다. 감염경로에 있어서 구강은 매우 중요한 역할을 하기 때문에 소아의 타액에서 H. pylori의 발현율을 조사하여 감염경로를 규명하기 위해 위장관과 관련된 증상 및 전신질환이 없는 10세 이하 20명과 10대 20명의 실험군과 20세 이상 71명의 대조군을 대상으로 연구하였다. 10세 미만에서 5명(25%), 10대에서 6명(30%) 그리고 20세 이상 17명(23.9%)에서 H. pylori가 타액에서 검출되었다. 실험군과 대조군간의 검출율 비교에 있어서 차이는 없었다(P>0.05). 이상의 결과를 종합해 볼 때 건강한 한국인 소아의 타액 내에서 H. pylori는 비교적 흔히 존재하며, 구강이 H. pylori 감염에 근원이 될 수 있음을 추론할 수 있다.
