幽门螺杆菌(Hp)的毒力决定其致病能力。感染了Hp的人群大部分无症状,只有少数人表现不同程度的症状,可能是感染了不同毒力的菌株所致。有细胞毒相关蛋白(CagA)基因的均为高毒株,与消化性溃疡、萎缩性胃炎、胃癌密切相关。对CagA^+株深入研究有助于加深对Hp致病机理的认识。  相似文献

胃十二指肠疾病幽门螺杆菌检出的意义   总被引:3,自引:2,他引:3  
目的:研究幽门螺杆菌(Hp)与消化性溃疡及慢性胃炎致病的关系。方法:因胃十二指肠疾病而做胃镜的患者,采取胃粘膜进行组织快速检菌,一分钟尿素酶(1min UT)试验和血清间接免疫荧光法进行检菌分析。结果:对5000例胃及十二指肠疾病Hp的组织检出率为88.1%。1min UT阳性率为62.9%,两种检菌法有显著差异(P<0.01)。十二指肠溃疡Hp检出为96.0%,胃癌和萎缩性胃炎Hp感染率为50.0%和59.2%,而1min UT只有41.5%阳性率。结论:胃癌和萎缩性胃炎均有粘膜层萎缩,腺体减少、粘液分泌功能降低,Hp茵不能适应强酸环境下生存。十二指肠溃疡和慢性胃炎多伴引起幽门口水肿和幽门变型,胃排空减缓。是导致Hp茵高检出率的重要因素。  相似文献

AIM: To study the characteristics of upper digestive tract diseases (UDTDs) in fishermen who live in Bohai Bay.METHODS: An investigation was carried out in 1488 fishermen with symptoms of UDTDs (aside from liver, biliary and pancreatic diseases) during the time period between December 1991 and February 1995. This investigation included medical history evaluations, physical, gastroscopic and pathological examinations, tests for Helicobacter pylori (H. pylori) infection, and analysis of the nitrate content in their drinking water.RESULTS: Among the 1488 subjects investigated, 1467 suffered from one or more of the 14 UDTD diseases, most of which were chronic atrophic gastritis (CAG, 1103 cases), peptic ulcers (268 cases), and cancer of the upper digestive tract (25 cases).CONCLUSION: The incidence rate of UDTDs tends to be high among fishermen due to their particular living habits, the high nitrate content of their drinking water, etc. In addition, the clinical manifestations of UDTDs in fishermen are significantly different from those of the inland residents.  相似文献

Background and study aims

Helicobacter pylori (H. pylori) has been implicated in the pathogenesis of most important gastro-duodenal diseases, such as gastritis, peptic ulcer disease (PUD) and gastric cancer. H. pylori upregulates the expression and activity of several matrix metalloproteinases (MMPs) in the gastric mucosa, but the role of MMP-3 and MMP-9 in infected patients with H. pylori have not been clearly defined yet. We examined mucosal MMP-3 and MMP-9 mRNA levels in gastric mucosa of H. pylori infected patients and evaluated the effects of virulence factors cagA and vacA allelic variants on these levels. We also determined correlation between mucosal MMP-3 and MMP-9 mRNA levels and types of disease.

Patients and methods

Total RNA was extracted from gastric biopsies of 50 H. pylori-infected patients and 50 H. pylori-negative patients. Mucosal MMP-3 and MMP-9 mRNA expression level in H. pylori-infected and non-infected gastric biopsies were determined by real time-polymerase chain reaction (PCR). Presence of vacA (vacuolating cytotoxin A) and cagA (cytotoxin associated gene A) virulence factors were evaluated using PCR.

Results

The levels of MMP-3 in gastric mucosa were not different between H. pylori-positive and H. pylori-negative patients. There was no correlation between MMP-3 mRNA expression and virulence factor (cagA and vacA allelic variants) and the different types of disease (gastritis and PUD) in infected patients. But MMP-9 mRNA expression was significantly higher in biopsies of H. pylori-infected patients compared to H. pylori-negative patients. Also mucosal MMP-9 mRNA expression in H. pylori-infected patients was significantly associated with cagA status PUD.

Conclusion

Our results suggest that MMP-9 might be involved in the pathogenesis of H. pylori. PUD could be associated with cag PAI-dependent MMP-9 upregulation.  相似文献

THE AIMS: To develop criteria for prediction of disorders of bone metabolism and improve prevention and treatment of osteopenia in gastroenterological patients on the basis of pathogenic features of its development. Recent literature data show that a number of digestive diseases exacerbate the risk of osteopenia/osteoporosis in patients with population risk factors. Reduced bone mineral density in patients with certain diseases of the digestive system occurs equally in both cortical and trabecular bone tissue, indicating the polyetiology osteopenia in this group of patients.  相似文献

目的研究2型糖尿病(T2DM)患者骨密度(BMD)变化情况。方法测定336例T2DM患者BMD,采用不同诊断标准,统计骨质疏松症(0P)检出率;对比OP组与非OP组生化指标差异并进行相关性分析。结果以低于峰值BMD2.5s及2.0s为诊断标准,OP检出率分别为8.90%和17.26%。BMD与年龄负相关(P〈0.01),与BMI正相关(P〈0.05),与女性绝经年数负相关(P〈0.01)。40-49岁组BMD与DM病程相关(P〈0.05)。结论年龄越大、BMI越低,绝经年数越长,越易发生骨质疏松。T-Score≤-2.0SD诊断OP可能适合本地区T2DM患者,但需进一步积累资料证实。  相似文献

Psoriasis is a common inflammatory skin disease, and conflicting data have been published about osteoporosis and bone turnover markers in patients with psoriatic arthritis. The aim of this study was to assess bone mineral density (BMD) and bone turnover markers in psoriatic patients with and without peripheral arthritis and to investigate the relationship between clinical parameters and markers of bone turnover. Forty-seven patients (24 women, 23 men) with psoriasis were included to the study. Demographic data and clinical characteristics were recorded. Erythrocyte sedimentation rate and C-reactive protein were assessed as disease activity parameters. BMD was determined for lumbar spine and total hip by dual X-ray absorptiometry (DXA). Serum Ca, P, alkalen phosphatase (ALP), and serum type I collagen cross-linked C telopeptide (CTX) were measured as bone turnover markers in all patients. The patients were divided into two groups according to their peripheral arthritis status. The clinical and laboratory variables, as well as bone mass status of the groups, were compared with each other. Eighteen patients had peripheral arthritis. All the female patients were premenopausal. None of the patients had radiologically assessed axial involvement. There was no significant difference between the BMD levels of psoriatic patients with and without arthropathy. One patient (5%) had osteoporosis, and nine (50%) patients had osteopenia in arthritic group, while eight (27.5%) patients had osteopenia in patients without arthritis. Serum CTX, ALP, Ca, and P levels were not significantly different in arthritic than in non-arthritic patients (p > 0.05). In patients with psoriatic arthritis, the duration of arthritis was negatively correlated with BMD values of lumbar spine and total femur and serum CTX levels, suggesting an association of increased demineralization with the duration of joint disease. In conclusion, psoriatic patients with peripheral arthritis with longer duration of joint disease may be at a risk for osteoporosis, which can require preventative treatment efforts.  相似文献
