Filter by:This study was conducted to investigate the effects of high-dose diphtherapy and bismuth quadruple therapy on H. pylori eradication on intestinal microecology, to clarify the changes in intestinal microbiota diversity and structure before and after the two treatment regimens, and to explore the relationship between different treatment regimens and intestinal microbiota dysbiosis; to further guide the safety and drug resistance of H. pylori eradication by the two treatment regimens. The expected results are to observe the changes of intestinal microbiota diversity and structure before and after treatment with the two treatment regimens.
By combining the measurement of blood pressure in both arms with the information of the four diagnoses of TCM, we try to form a diagnostic model of "five diagnoses combined with ginseng" based on TCM Zang-fu syndrome differentiation. It can further objectify and visualize the fuzzy four diagnostic indicators of TCM. In order to solve the problem of data differentiation of TCM four diagnoses, and optimize the five diagnoses of TCM conjunctive index, explore the establishment of TCM intelligent diagnosis and treatment and contact evaluation computer system
The clinical management of H. pylori infection depends essentially on two factors, prevalence and local resistance. In Germany, only limited data from rather small cohorts currently exist regarding both factors. Knowledge of the current prevalence (accounting for socioeconomic factors and age) is important for the selection of suitable detection methods, as this influences the positive and negative predictive value of the respective diagnostic methods. Current data on antibiotic resistance are essential for efficient therapy. In this clinical study, we will collect data on the frequency and severity of H. pylori infections and then, after endoscopic examination, on antibiotic resistance. Knowledge of the resistance situation is necessary for the selection of suitable therapeutic regimens. Furthermore, molecular methods for resistance detection are to be compared with conventional microbiological methods in order to be able to detect resistance more quickly. Furthermore, we aim to identify specific parameters for early detection of patients at particularly high risk of gastric cancer or with precancerous lesions due to infection. The aim is to identify carcinogenesis-relevant factors such as gastric microbiome signatures that will make it possible to identify patients who are most likely to benefit from prophylactic eradication therapy in terms of risk stratification.
Painless endoscopy technology can make patients comfortable under anesthesia, but because of the painless inside.The diagnosis and treatment time of endoscopic examination is short, and the transport is fast. Anesthesia related wind such as deep breathing depression and hypoxemia will occurRisks.Eeg depth monitoring can assist anesthesiologists to evaluate the depth of anesthesia and reduce the risk. Artificial intelligence is adopted.There are few reports on the evaluation of anesthesia depth and drug dosage by electroencephalogram (EEG) monitoring in outpatient patients with painless gastroenteroscopy.
To explore the efficacy and safety of "Manpixiao" in the treatment of Chronic Atrophic Gastritis.
This is an observational cohort study of clinical efficacy study.The purpose of this topic is to evaluate the efficacy and safety of Modified Liujunzi Decoction based on syndrome differentiation in patients with chronic atrophic gastritis(CAG) after HP eradication.Taking Modified Liujunzi Decoction as the observation group and Weifuchun routine treatment as the control group, so as to provide evidence for the treatment of CAG and reduce the risk of gastric cancer. A total of 284 patients were included. The curative efficacy, symptom score and adverse events will be recorded and analyzed.
Purpose: The study is a cross-sectional observational study designed to determine if eosinophilic gastritis (EG) results in gastric motility impairment. Hypothesis: Gastric dysfunction occurs in the natural history of EG but is underdiagnosed due, in part, to contraindications to the use of the standard meals used in gastric emptying studies.
Eosinophilic gastrointestinal disorders (EGIDs) are a heterogeneous group of emerging chronic inflammatory diseases that may affect different gastrointestinal (GI) tracts. Based on the anatomical site involved, EGIDs are distinguished into eosinophilic esophagitis (EoE) and non-esophageal forms, which are subdivided into eosinophilic gastritis (EoG), gastroenteritis (EoGE), and colitis (EoC). EoE is considered the prototype of EGIDs. Since the first description of a case series of patients with EoE, fundamental scientific advances have been achieved, culminating in the redaction of international diagnostic and therapeutic guidelines. In contrast to EoE, non-esophageal forms of EGIDs are still a clinical enigma with evidence limited to a few retrospective studies. In the last decade, an increase in the prevalence of EGIDs has been observed in the pediatric age. Unfortunately, the epidemiology of EGIDs in Italy is still inconsistent and clear estimates are not available. Firstly, this study will allow us to assess and clarify several clinical and epidemiological aspects of pediatric EGIDs, in particular: 1. prevalence and incidence of pediatric EGIDs in Italy, 2. the clinical features and potential phenotypes of pediatric EGIDs with potential impact on therapy and management, 3. diagnostic work-up and adherence to the EoE international guidelines to improve the management, quality of care, and quality of life of affected patients. This study has no ethical problems since EoE patients are treated according to international guidelines and those with non-esophageal EGIDs according to the latest scientific evidence.
Chronic atrophic gastritis (CAG) is a common and frequently-occurring disease, characterized by atrophy of gastric mucosal epithelium and glands, thinning of the mucosa, thickening of the submucosal muscle layer, intestinal metaplasia, and atypical hyperplasia. The course of the disease is protracted and often recurrent, which seriously affects the work and physical and mental health of the patient. Moreover, epidemiological studies have shown that the risk of gastric cancer in patients with chronic multifocal atrophic gastritis is significantly higher than that of the general population. Because CAG intestinal metaplasia and dysplasia can easily develop into gastric cancer, the World Health Organization (WHO) listed CAG's gastric mucosal atrophy, intestinal metaplasia and dysplasia as precancerous lesions of gastric cancer in 1978. Therefore, reversing and disappearing the precancerous state of gastric cancer is an effective measure to prevent the occurrence of gastric cancer. The cause of CAG is complicated. Modern medicine believes that CAG is closely related to biological factors, physical and chemical factors, immune factors, and genetic factors. At present, there is no specific treatment, but symptomatic treatment is the main treatment. The disease belongs to the categories of "stomach pain" and "suffocation" in traditional Chinese medicine. In many years of surveys and studies in Mainland China, it is found that Dendrobii granules have a good effect on chronic atrophic gastritis. It is planned to explore the possibility, effectiveness and safety of Dendrobii granules in the treatment of chronic atrophic gastritis through clinical trials. 20 subjects will be randomized into the treatment group and placebo group with 18 weeks of treatment.
Helicobacter pylori is a pathogenic bacteria transmitted from individual to individual, being scientifically recognized as an agent who causes persistent inflammatory activity on the gastric mucosa. This pathogen represents a Global Health problem, as shown in a systematic review by Hooi et al. Besides regional differences, more that half of the world population is expected to have already been infected by this bacteria. In Portugal, research studies estimate that more than 80% of the adult population has already contacted with H. pylori. H. pylori infection is associated with active chronic gastritis in every colonized patient, what may consequently lead to peptic ulcer disease, atrophic gastritis, gastric adenocarcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma. For that reason, H. pylori infection is considered to be a disease, independently of the presence of gastrointestinal symptoms. Additionally, H. pylori has been classified as a confirmed carcinogen (class I) by the International Agency for Research, being responsible for carcinogenic pathways conducting to both gastric adenocarcinoma and lymphoma. This fact gains a particular relevance taking into account that gastric cancer is one of the most prevalent cancers worldwide. On other hand, more than 75% of the gastric cancers occur following H. pylori infection. Thus, H. pylori eradication constitutes an essential Public Health measurement, being inclusively considered a cost-effective method to decrease the gastric cancer burden, by promoting pre-malignant lesions regression, such as atrophic gastritis, and by delaying the disease progression in case of intestinal metaplasia or dysplasia. Maastricht V consensus is a document updated in 2016, including the major recommendations regarding H. pylori diagnosis, follow-up and treatment. It highlights the emergence of antibiotic resistances and how they must influence clinical practice, namely the choice of antibiotic regimens, as successful eradication has become less frequent with more prevalent antibiotic resistances. This is the case of clarithromycin and metronidazol, both currently recommended as first-line options by the Portuguese Society of Gastroenterology. In fact, a systematic review conducted in 2018, aiming to evaluate antibiotic resistances on the Portuguese population observed that clarithromycin, metronidazole and double resistance occurred in 42%, 25% and 20% of the individuals, respectively. Nowadays, Maastricht V guidelines recommend quadruple regimens containing bismuth, such as Pylera (r), as the first-line option in areas with significant double resistance to metronidazole and clarithromycin. Another option currently being investigated is the double therapy with amoxicillin in high doses and proton pump inhibitor. This has become a particularly attractive alternative due to its efficacy, good tolerability and significantly low resistance (<1%) among the European population. The aim of this clinical trial is to compare both regimens - pylera (r) and high-dose amoxycillin - in H. pylori eradication, regarding their efficacy, tolerability and side effects, in order to asses viable therapeutic options in a population with progressively increasing resistances to alternative regimens currently recommended.
