肝硬化大鼠小肠壁结构改变与小肠细菌过度生长和细菌转位的关系的研究 总被引:5,自引:0,他引:5
目的:观察肝硬化大鼠小肠壁结构的变化、小肠细菌过度生长和肠道细菌转位的情况,并探讨其在肠源性内毒素血症中的作用。方法:采用CCl4诱导肝硬化大鼠模型,分别取外周静脉和门静脉血测血清内毒素水平,并获取肠系膜淋巴结、肝、脾和近端空肠内容物做细菌培养。部分空肠组织作病理切片。结果:所有的肠道细菌转位(BT)均发生在有小肠细菌过度生长(SIBO)的大鼠中,肝硬化大鼠的SIBO发生率为50%(10/20),BT的发生率为35%(7/20)。正常大鼠无一只出现SIBO。肝硬化大鼠的血清内毒素水平高于正常大鼠(P<0.01).在有SIBO的肝硬化大鼠的血清内毒素水平又高于其他的肝硬化大鼠,尤以发生BT的大鼠最高。病理检查发现发生BT的肝硬化大鼠空肠绒毛变短、破坏,炎症细胞浸润增多。结论:小肠细菌过度生长和肠道细菌转位是肝硬化肠源性内毒素血症发生的重要原因之一,肠内高内毒素浓度可能与肠黏膜结构改变有关。 相似文献

Non-invasive methods to detect small intestinal bacterial overgrowth often lack specificity in patients who have undergone an ileal resection or have an accelerated intestinal transit. Since elevated serum unconjugated bile acid levels have been found in patients with clinical signs of bacterial overgrowth, we studied the clinical value of unconjugated serum bile acids as a marker of small intestinal bacterial overgrowth. Patients with culture-proven bacterial overgrowth had significantly elevated fasting unconjugated serum bile acid levels (median and range: 4.5; 1.4-21.5 mumol l-1) as compared to healthy subjects (0.9; 0.3-1.7 mumol l-1, P less than 0.005), to persons with an accelerated intestinal transit (1.0; 0.3-1.9 mumol l-1, P less than 0.005) and to persons who have undergone an ileal resection (2.1; 0.7-3.6 mumol l-1, P less than 0.005). The same was true 30 and 60 min after ingestion of a Lundh meal. Serum unconjugated bile acid levels above 4 mumol l-1 were found in eight of 10 patients with culture-proven small intestinal bacterial overgrowth whereas serum levels above 4 mumol l-1 were found in none of the patients from the three control groups. These results suggest that determination of unconjugated serum bile acids is of clinical value in the evaluation of patients suspected of small intestine bacterial overgrowth. 相似文献

The intestinal microbiota and its role in health and disease processes have been the subject of several studies. It is known that changes in the intestinal microbiota occur due to several factors, such as the use of medication, age, lifestyle and diseases, which can modify intestinal homeostasis and lead to excessive growth of bacteria in the small intestine, triggering a clinical condition called small bowel bacterial overgrowth (SIBO). Individuals with SIBO may present gastrointestinal symptoms ranging from nausea, diarrhea and/or constipation, and flatulence to distension and abdominal pain, resulting from poor absorption of nutrients or changes in intestinal permeability. The gold-standard treatment is based on the use of antibiotics to eradicate bacterial overgrowth. Some studies have evaluated diets in the treatment of SIBO; however, the studies are of low methodological quality, making extrapolation of the results to clinical practice unfeasible. Thus, there is still not enough scientific evidence to support a specific type of diet for the treatment of SIBO. 相似文献

Helicobacter pylori infection and small intestinal bacterial overgrowth–more than what meets the eye
Helicobacter pylori (H. pylori) infection is very common and affects a significant proportion of the world population. In contrast, the prevalence of small intestinal bacterial overgrowth (SIBO) in the general population is not well understood. There can be coexistence of both disease states in a given patient and their clinical symptoms may also overlap with one and another. There is no clear clinical guidelines for testing for and treating SIBO in patients with H. pylori infection. This review article explores the available evidence on the relationship between H. pylori infection and SIBO, diagnosis and treatment of these entities and also comments on associated non-gastrointestinal conditions. 相似文献

Keystone Symposium on Frontiers in HIV Pathogenesis, Therapy and EradicationWhistler, BC, Canada, 26–31 March 2012Although HAART can suppress plasma viral loads to undetectable levels, individuals infected with HIV-1 harbor latent reservoirs of integrated proviruses that re-emerge upon the cessation of drug treatment. The 2012 Keystone Symposium on Frontiers in HIV Pathogenesis, Therapy and Eradication highlighted the current understanding of latent infection and new methods to activate and target these reservoirs for eradication. This report focuses on a select few aspects of the discussion, including the extent that ongoing replication might contribute to the persistent viral reservoir, recent advances in activating the expression of latent proviruses, progress in developing effective animal models and potential avenues to eradicate the cells that constitute the latent reservoir. 相似文献

The aim of this study was to elucidate the consequences of small bowel bacterial overgrowth (SBBO) after total gastrectomy. A total of 127 patients, evaluated for SBBO with a radiographically controlled H2 -breath test (subgroup I, without SBBO, n = 80; subgroup II, with SBBO, n = 47) after potentially curative total gastrectomy for gastric malignancy, were uniformly evaluated. Mean time since operation was significantly shorter in subgroup II than in subgroup I [370 days, confidence interval (CI) 96–645 days, vs. 687 days, CI 397–976 days; P < 0.01]. Controlling for this difference, there were no other significant differences in symptoms and signs between the subgroups except for the medicosocial functioning measured with the Edinburgh Rehabilitation Status Scale (ERSS). The mean ERSS showed significantly better medicosocial functioning in subgroup I than in subgroup II [3.7 (CI 2.2–5.2) vs. 5.1 (CI 3.0–7.0); P < 0.05]. After total gastrectomy, patients without SBBO did not differ significantly from patients with SBBO in most parameters. Medicosocial functioning was significantly poorer in the latter. 相似文献
