研究背景:目前全世界有近50%人口感染了幽門螺桿菌（Helicobacter pylori,H.pylori）,我國H.pylori感染率達(dá)50%。已證明H.pylori感染可導(dǎo)致包含慢性胃炎、消化性潰瘍、胃癌和胃粘膜相關(guān)組織淋巴瘤在內(nèi)的多種消化系統(tǒng)疾病;同時(shí)H.pylori感染也與不明原因的缺鐵性貧血、代謝綜合征、心腦血管疾病、免疫性血小板減少性紫癜等胃腸外疾病相關(guān)。根除H.pylori可延緩慢性萎縮性胃炎的發(fā)展,降低早期胃癌患者異時(shí)性胃癌的發(fā)生率,或可有效減輕我國胃癌疾病負(fù)擔(dān)。全球范圍內(nèi)H.pylori根除失敗現(xiàn)象越來越普遍,其主要原因包括H.pylori對抗生素耐藥率逐漸升高,患者對根除治療方案依從性不佳,臨床用藥方案不規(guī)范等;反復(fù)的根除治療失敗繼而加劇了補(bǔ)救根除治療的困難,造成部分H.pylori感染遷延難治。有學(xué)者提出患者接受共識推薦的四聯(lián)方案根除治療失敗3次及以上考慮為難治性幽門螺桿菌感染。針對難治性幽門螺桿菌感染,目前指南和共識尚缺乏推薦的根除治療方案。研究目的:本研究旨在探求14天改良序貫療法對難治性幽門螺桿菌感染的根除療效,分析其難治性幽門螺桿菌抗生素耐藥性特點(diǎn),并結(jié)...
