摘　　要：AIM： To detect whether there is Helicobacter pylori （Hpylori） colonization in the pharynx mucous membrane of healthy people and whether chronic pharyngitis is related to Hpylori infection. METHODS： Fifty cases of chronic pharyngitis refractory over three months were prospectively studied from March 2004 to August 2004 in the otolaryngology outpatient department of the Second Hospital of Xi＇an Jiaotong University. Template-directed dye-terminator incorporated with fluorescence polarization detection （TDI-FP） and modified Giemsa stain were used to examine pharynx mucous membrane tissue for H pylori colonization in the patients with chronic pharyngitis and the healthy people as a control group. RESULTS： In the control group, no people were detected to have Hpylori in the pharynx. In contrast, in 50 cases with chronic pharyngitis, 19 （38.0%） cases were H pylori positive with a TDI-FP assay and 4 （8%） cases were TDI-FP positive with Giemsa staining in the pharynx. Sixteen of the 50 pharyngitis cases had stomach ailment history, 11 cases （68.8%） of these 16 patients were determined to be H pylori positive in the pharynx with the TDI-FP assay. 2,2 test showed that this infection rate was remarkably higher （P= 0.0007） than that in the cases without stomach ailment history. Giemsa staining showed that 3 cases （18.8%） of the patients with stomach ailment history were infected with H pylori in the pharynx, which was remarkably higher （P = 0.042） than that in the patients without stomach ailment history （1 case, which was 2.9%）. CONCLUSION： H pylori may not be detected in the pharynx of healthy people. Chronic pharyngitis may be related to H pylori infection. The infection rate with Hpylori in the pharynx is higher in patients with stomach ailment histories than in patients without stomach ailment histories, suggesting that chronic pharyngitis may be related to stomach ailment history.AIM:To detect whether there is Helicobacter pylori(Hpylori)colonization in the pharynx mucous membraneof healthy people and whether chronic pharyngitis is re-lated to Hpylori infection.METHODS:Fifty cases of chronic pharyngitis refrac-tory over three months were prospectively studied fromMarch 2004 to August 2004 in the otolaryngology outpa-tient department of the Second Hospital of Xi'an JiaotongUniversity.Template-directed dye-terminator incorporat-ed with fluorescence polarization detection(TDI-FP)andmodified Giemsa stain were used to examine pharynxmucous membrane tissue for Hpylori colonization in thepatients with chronic pharyngitis and the healthy peopleas a control group.RESULTS:In the control group,no people were de-tected to have Hpylori in the pharynx.In contrast,in 50cases with chronic pharyngitis,19(38.0%)cases wereH pyIori positive with a TDI-FP assay and 4(8%)caseswere TDI-FP positive with Giemsa staining in the phar-ynx.Sixteen of the 50 pharyngitis cases had stomachailment history,11 cases(68.8%)of these 16 patientswere determined to be H pylori positive in the pharynxwith the TDI-FP assay.x^2 test showed that this infectionrate was remarkably higher(P=0.0007)than that in thecases without stomach ailment history.Giemsa stainingshowed that 3 cases(18.8%)of the patients with stom-ach ailment history were infected with H pylori in the pharynx,which was remarkably higher(P=0.042)thanthat in the patients without stomach ailment history(1case,which was 2.9%).CONCLUSION:H pylori may not be detected in thepharynx of healthy people.Chronic pharyngitis maybe related to H pylori infection.The infection rate withHpylori in the pharynx is higher in patients with stomachailment histories than in patients without stomach ail-ment histories,suggesting that chronic pharyngitis maybe related to stomach ailment history.
