Case Study Of Helicobacter Pylori

Great Essays
Helicobacter pylori is an infection that is closely associated with peptic ulcer disease. It took more than a decade before peptic ulcer disease was accepted as an indication for H. pylori eradication therapy.
Introduction
Helicobacter pylori, more commonly referred to as H. pylori, has infected millions of people around the world. For centuries people living with the disease were misdiagnosed with other gastric illnesses. One of the most common misdiagnoses of the gastro-intestinal issues were peptic ulcers. Peptic ulcers were thought to be either stressed induced, a reaction created after patients ate certain spicy foods, or an over use of non-steroidal inflammatory drugs (NSAIDS) which are sold and available over the counter.

Barry J. Marshall was an internist who, in 1981, started his gastroenterology rotation at Royal Perth Hospital and where he met Dr. Warren. Dr. Warren made a list of patients who had curved bacteria on their biopsies and needed help following up with a diagnosis. Dr. Marshall agreed to assist in researching the spiral bacteria in hopes of finding questions on one of his patients having sever stomach pains without a proper diagnoses. It was Dr. Marshall who noticed that cultures from a campylobacter jejuni and the curved microorganism on the cultures taken from the gastro patients were similar. Campylobacter organisms are spiral-shaped bacteria that can cause disease in humans, this illness is more commonly known as food poisoning. Human illness of the Campylobacter results in diarrhea, cramping, abdominal pain, and fever within two to five days after exposure to the organism. Dr. Marshall researched thousands of pages of medical books to try and find a link in the spiral organism, its symptoms, and to find an explanation of the correlations to Campylobacter. What he found was astounding, there were many cases of the organisms being reported but extremely vague, giving little to no information. Dr. Warren’s study results of 100 patients found the correlation they were looking for. Out of the 100 patients with gastritis, 25 had gastric spiral bacteria and only 13 patients with a duodenal ulcer had the organism. Both doctors hypothesized that peptic ulcers are caused by …show more content…
Pylori infection has made a dramatic difference in the lives of many Western countries over the past few decades. The H. pylori infection is generally easy to diagnose, using either invasive or non-invasive methods. Dr. Marshall devised the most widely used invasive biopsy-based test named the rapid urease test or the CLO test. The rapid urease test depends on the fact that H. pylori has tons of enzymes and the patient agrees to have an endoscopy. The rapid test has a pH indicator that will change from yellow to red giving a positive result. Breath test for H. pylori is non-invasive with a urea drink solution, it’s simple but requires a spectrometer for analysis to detect the carbon dioxide in breath. The stool test is the most accurate and more importantly, is non-invasive. There are other tests for H. pylori to include: commercial test kits, serological test and surgery. If a patient tests positive for H. pylori, the most popular treatment is a combination of a proton pump inhibitor with two antibiotics, named triple therapy. The eradication rate for this regimen is close to perfect. The downfall to using antibiotics is the mutation of the H. pylori becoming antibiotic-resistant. The strain itself varies from the country it originated from “28% of H. pylori infection in Europe is metronidazole-resistance compared with almost 75% in Africa” (O’Connor 42). The H. pylori infection has issues with eradication in lower socio-economic communities were

    Numerous studies have been done on the causes and effects of Ulcerative Colitis in the body that ultimately begin and progress through the large intestine. These studies have led to information that allows physicians to help their patients control the symptoms of this disease and enable them to lead a normal life. However, through the research that has been done no significant information has led to the cure of this disease or what truly causes it in the first place. The cause for this disease must be determined to allow prevention and there must be research leading to the cure of this disease; not only treatment to reduce the symptoms and manage the disease. This paper will examine the research done on Ulcerative Colitis to determine the steps…

    HISTORY OF PREVELANCE: It is not clear when gas gangrene was officially discovered, although records from the Civil War indicate it was known at the time (Gillett, 1987, p. 280). Hospital gangrene was much more common than Gas Gangrene during the Civil War because it spread through direct contact (Gillett, 1987, p. 280). Gas gangrene was relatively uncommon during the Civil War, but became much more common in later wars such as World War I and World War II. In World War I, gas gangrene was the second most important cause of death among soldiers (US Army Surgeon General’s Office, 1929, p. 414).…

    Introduction Though being a patient in a hospital may be vital to improving one’s health, there are often risks associated with staying in a hospital. One of these risks occurs when an individual acquires a nosocomial infection, otherwise known as a hospital-acquired infection. These infections are classified as hospital-acquired infections, because the individual becomes infected after visiting or staying in a health care facility (Ducel et al., 2002). One of the most common hospital-acquired infections that a patient may obtain is a Clostridium difficile infection.…

Inflammatory Bowel Disease refers to chronic and relapsing inflammatory disorders which two main different disease include Crohn’s Disease and Ulcerative Colitis. In 1932 by Drs Burrill Crohn, Gordon Oppenheimer, and Leon Ginzburg described as an idiopathic transmural chronic inflammatory disorder affecting the gastrointestinal tract. In 1875 by Drs Wilks and Moxon first described and identified UC (ulcerative colitis) as noninfectious cause[1]. Some of the suspected etiology including life style, immune factors, gut flora, environmental factors, and genetic variation are strongly believed to be key holder.…

    Clostridium difficile is a gram-positive anaerobic bacillus that forms spores and it is known as the most common cause of hospital-acquired diarrhea. Gastric acid was not believed to be important in protection agent against C difficile infection due to acid-resistant spores being allegedly the main vector of transmission. This theory has been challenged by numerous studies that have found a higher risk of C difficile infection in PPI users. PPIs may increase the risk of C difficile infection by increasing the capability of the spores to convert into a vegetative state and survive in the lumen of the stomach. Studies have shown a strong statistical correlation between PPI use and C. difficile infection.…

Introduction Helicobacter pylori (H. pylori) has infected humans for more than 58000 years (1).yet it largely escaped notice until it was cultured by Marshall and Warren(2).research on Helicobacter Pylori changed paradigms regarding disease causation. Physicians previously attributed ulcers to stress or anxiety and did not believe that bacteria could cause cancer (3). .After 1983, when it was discovered that the stomach could be colonized by bacteria (4). increasing evidence has shown that H. pylori are a pathogen closely related to a variety of gastric conditions.…

    There are Gastric Ulcers, which are ulcers developed on the inside of the stomach, the Esophageal Ulcers which are developed in the esophagus, and lastly, the Duodenal Ulcers which are developed in the first section of the small intestine or known as the Duodenum. All of the following Peptic ulcers are commonly described as a developed sore locating in various positions of the digestive system. The stomach and the Duodenum both have a layer of mucus to protect it from the acids produced by the stomach used to break down foods. A PPU occurs when the inside of the stomach or the small bowel is exposed to acid where there is no mucus. The ulcer attacks the tissue causing…

    During my dialysis experience I found it to be very informative and interesting. We were not allowed to touch the patients or help with any care but the staff was interactive and explained was they were doing. The staff also was able to provided scenarios of different complications that happened and how they 'd respond. By the end of the first day I was able to see what the caregiver would due if a patient had muscle cramps, was short of breath and had chest pain. The first day I mostly interacted with the staff and was able to see medical side of the whole procedure such as learning and seeing how to dispose of contaminated equipment and what machines were used.…
