Active clinical trials for "Helicobacter Infections"

This study compared efficacy and safety of basic triple therapy including Ilaprazole 10mg, Levofloxacin 500mg and Amoxicillin 1000mg BID for 10 days on the first line eradication treatment of H.pylori

To examine markers of underlying chronic inflammation and infection as potential risk factors for future myocardial infarction (MI), stroke (CVA), and venous thromboembolism (VTE) in plasma samples collected at baseline from healthy participants in the Physicians' Health Study (PHS).

Helicobacter pylori (H. pylori), a bacteria transmitted from human to human through upper digestive tract as well as fecal-oral transmission, had infected more than half of people around the world. However, the quantity of H. pylori in oral cavity and its influence on oral microbiota remains to be unclear. The aim of the present study was to examine the effects of H. pylori infection as well as its eradication on oral microbiota.

People nowadays tend to have irregular diet and routine due to the stress at work. This condition may cause intestinal microflora imbalance, and in the long term may lead to constipation, diarrhea, gastroenteritis, gastric ulcer and other gastrointestinal diseases. Helicobacter pylori infection, which can trigger gastrointestinal inflammation and ulcer, is commonly treated by antibiotics. This treatment, however, can reduce the diversity of the intestinal microflora, causing diarrhea, flatulence and nausea. Clinical trials showed that probiotics and prebiotics supplementation could regulate gastrointestinal function, including alleviating constipation, ameliorating antibiotic-associated diarrhea and flatulence, enhancing the effect of H. pylori treatment, and restoring the balance of intestinal microflora. This Probiotics product is a supplement containing several types of probiotics and prebiotics which has been marketed for years. This project aims to observe the effectiveness of Probiotics product consumption by H. pylori-infected patients in relieving the gastrointestinal symptoms and restoring their intestinal microflora.

Cystic fibrosis (CF) is the most common lethal autosomal recessive disease among Caucasians. While the pulmonary disease in CF receives most of the attention, gastrointestinal diseases occur in >95% of CF individuals and can contribute to significant morbidity, mortality and a decreased quality of life. The abdominal pain in CF is usual chronic in nature, and the etiology is not usually found, despite medical testing for standard causes of abdominal pain. Helicobacter pylori (Hp) is increasingly being recognized as the etiology of peptic ulcer disease and other upper and lower gastrointestinal tract diseases.1 The role that Hp plays in CF abdominal pain has not been elucidated. Our long-term goal is to understand relationship between chronic HP infection and abdominal pain in pediatric CF patients. The specific objective of this proposal is to utilize current state-of-the-art testing for HP to determine the prevalence of Hp in our CF patients age 5 and older. The central hypothesis is that Cystic fibrosis subjects with significant abdominal pain will have an increased incidence of Helicobacter pylori as determined by the urea breath test and stool antigen test. The rationale for the proposed research is that once we elucidate a causal relationship between CF patients with abdominal pain and Hp, we can begin treatment of this infection to improve quality of life.

The purpose of this study is to know the distribution of HP in stomach before use of PPI, during use of PPI, and after stop of PPI.

Dual-focus with narrow-band imaging (DF-NBI) is a novel technique to improve the quality of images of the irregular mucosal structures and microvessels of gastric neoplasms. The investigators compare this technique with conventional white light (WL) endoscopy to predict Helicobacter pylori infection.

The study was a cross-sectional single-center study, conducted at Renji Hospital, Shanghai Jiaotong university school of medicine. We retrieved the medical records of all patients who had undergone upper gastrointestinal endoscopy from January 1, 2013 through December 31, 2019. The medical records were analyzed for the prevalence of H. pylori infection in patients with peptic ulcers.

This study will examine whether infection with Helicobacter pylori bacteria may cause inflammation of the eye's surface. Although most people who are infected with H. pylori do not have symptoms, the bacteria can cause several diseases, including gastritis-stomach inflammation, stomach ulcers or, rarely, stomach cancer, and certain types of lymphoma. H. pylori has also been associated with autoimmune disorders, in which the patient's immune system attacks the body's own tissues. People who have been infected with H. pylori, with and without dry eye, may be eligible for this study. Candidates are screened with a medical history, a blood test to determine H. pylori infection, and an eye examination. The examination includes measurements of visual acuity, eye pressure, and tear production. To measure the amount of tear production, a small piece of filter paper is inserted over the eyelid on the side and collects tears over a 5-minute period. Drops of two colored dyes (orange and green) are placed in the eyes to see if there are any dry areas. Screening also includes examination of the pupils and eye movements, the lens, and the back of the eye, including the retina. Participants will also have a few cells collected from the surface of the eye. After the eyes are numbed with anesthetic eye drops, a swab (like a Q-tip) is rolled over the surface of the white part of the eye to collect small samples of the superficial layer of the conjunctiva - a transparent membrane covering the eyeball. The specimens are analyzed by special laboratory techniques to determine whether H. pylori has infected the eye.

The purpose of this study is to investigate the trend of eradication rates of first-line triple therapy for Helicobacter pylori in recent ten years and clinical factors that affect the eradication in Korean.
