Abstract

Background/Aims: The increasing trend of antibiotic resistance emphasizes the need for the assessment of eradication rate of first and second-line therapy for Helicobacter pylori (H. pylori) infection. The reinfection rate depends on the geographical, national, or socioeconomic status of the patients. The aim of this study was to evaluate the recent 5-year changes of eradication rates and the reinfection rates after the successful eradication of Helicobacter pylori infection for 3-years follow-up in Bucheon, Korea. Methods: From February 2001 to August 2006, 3,267 patients with H. pylori-positive peptic ulcer disease received the first-line therapy for 7 days. The 317 patients who failed to the first-line therapy received the second-line therapy for 7 days. The 167 patients with 3-years follow-up after the successful eradication were included. 13C-urea breath tests or rapid urease tests and histologies were assessed to determine the H. pylori status after the eradication. Results: The eradication rate of first-line therapy was 83.7% in 2001, 83.4% in 2002, 83.7% in 2003, 85.9% in 2004, 87.2% in 2005, and 81.8% in 2006 by per protocol analysis (PP), respectively. The eradication rate of second-line therapy was 80.0% in 2002, 86.8% in 2003, 89.7% in 2004, 98.0% in 2005, and 78.8% in 2006 by PP. The cumulative reinfection rate was 6.0%. The annual reinfection rate was 2.0%. The recurrence rate of peptic ulcer was 17.2% in the patients without reinfection and 50% with reinfection. Conclusions: The eradication rate for H. pylori have not changed in the recent 5-years. The annual reinfection rate was low. The successful eradication of H. pylori was effective for preventing the recurrence of peptic ulcers. (Korean J Gastroenterol 2007;50:170-175)

목적: H. pylori 제균율과 재감염률은 지역에 따라 다양하게 보고 되고 있다. 저자들은 최근 5년 동안 경기도 부천지역 주민을 대상으로 일차 및 이차 제균치료의 연도별 제균율 변화와 재감염률을 알아보고자 하였다. 대상 및 방법: 2001년 2월부터 2006년 8월까지 순천향대학교 부천병원 소화기내과 외래에 내원하여 상부위장관내시경 검사를 실시하여 위궤양 또는 십이지장 궤양을 진단받고 H. pylori 감염을 확인하여 일차 제균치료를 시행한 3,267명의 환자와 일차 제균치료에 실패하여 이차 제균치료를 시행한 317명의 환자를 대상으로 제균율을 조사하였다. 또한 성공적으로 제균 치료가 된 환자 중에서 3년 이상 추적 관찰한 167명을 대상으로 재감염률 및 소화성 궤양의 재발률을 조사하였다. H. pylori 감염은 내시경 검사를 통한 조직 검사와 신속요소분해효소 검사로 판단하였고 일차 제균치료는 삼제요법, 이차 제균치료는 사제요법을 시행하였으며, 제균 판정은 제균요법을 시행하고 4-6주가 지난 후 신속요소분해효소 검사와 조직검사, 13C-요소호기검사를 통해 판정하였으며 이 후 추적 관찰 역시 내시경 검사와 함께 신속요소분해효소 검사나 13C-요소호기검사를 통해 판정하였다. 결과: 일차 치료 제균율은 PP 분석에서 2001년은 83.7%, 2002년은 83.4%, 2003년은 83.9%, 2004년은 85.9%, 2005년은 87.2%, 2006년은 81.8%로 나타났으며 각 연도별 제균율은 유의한 차이를 보이지 않았다. 이차 치료 제균율은 PP 분석에서 2002년은 80.0%, 2003년은 86.8%, 2004년은 89.7%, 2005년은 98.0%, 2006년은 78.8%로 나타났으며 각 연도별 제균율은 유의한 차이를 보이지 않았다. 재감염률은 3년 동안 추적 관찰한 167명 중 총 10명에서 재감염이 발견되어 총 누적 재감염률은 6.0%였고, 연간 재감염률은 2.0%로 나타났다. 궤양 재발은 재감염이 발생하지 않은 환자에서는 17.2%, 재감염 환자군에서는 50%로 나타났으며 이 두 군 간에 유의한 차이를 보였다. 결론: 경기도 부천지역에서 일차 제균치료로서 PPI를 기본으로 하는 삼제 병합요법과 이차 제균치료로서 사제 병합요법은 최근 5년 동안 제균율 변화 경향을 보이지 않아 아직까지 유용한 치료법으로 생각한다. H. pylori의 연간 재감염률은 2.0%였으며 재감염이 있는 환자군에서 궤양 재발이 유의하게 높아 성공적인 제균치료가 궤양의 재발 억제에 영향을 미침을 알 수 있었다.색인단어: Helicobacter pylori, 제균율, 재감염률
