Scientists Create Tiny Stomachs From Stem Cells

Posted 29 Oct 2014 by Drugs.com

WEDNESDAY, Oct. 29, 2014 – Scientists who used stem cells to create miniature human stomachs in the laboratory say their breakthrough could provide a new way to learn more about the development and treatment of stomach diseases. The team used human pluripotent stem cells – which can become any type of cell in the body – to grow the functional miniature stomachs, to study infection by H. pylori bacteria, a major cause of ulcers and stomach cancer. The miniature stomachs offer many research opportunities, including modeling early stages of stomach cancer, developing new drugs and learning more about obesity-related diabetes, according to principal investigator Jim Wells. He's a scientist in the developmental biology and endocrinology divisions at Cincinnati Children's Hospital Medical Center. "Until this study, no one had generated gastric [stomach] cells from human pluripotent stem ... Read more

Could the 'Ulcer Bug' Guard Against Obesity?

Posted 5 Jun 2014 by Drugs.com

THURSDAY, June 5, 2014 – Countries with low rates of the ulcer-causing bacterium H. pylori tend to have high rates of obesity, a finding that researchers say they see as more than a chance correlation. Looking at 49 studies from Australia, Europe, Japan and the United States, the review authors found that in several countries such as Italy, Japan, Portugal and Spain, the majority of the population carried H. pylori. And those countries had relatively low rates of obesity, ranging from 3 percent in Japan to about 15 percent in Spain. That was in contrast to the United States, for example, where about one-third of adults are obese and around the same percentage carry H. pylori. None of that, however, proves cause and effect, cautioned an obesity expert who was not involved in the study. "This study found a simple correlation, at the population level," said Christopher Ochner, an ... Read more

Infection Causes 1 in 6 Cancers Worldwide: Study

Posted 9 May 2012 by Drugs.com

WEDNESDAY, May 9 – One in six cancers worldwide is caused by preventable or treatable infections, a new study finds. Infections cause about 2 million cancer cases a year, and 80 percent of those cases occur in less developed areas of the world, according to the study, which was published online May 8 in The Lancet Oncology. Of the 7.5 million cancer deaths worldwide in 2008, about 1.5 million were due to potentially preventable or treatable infections. "Infections with certain viruses, bacteria and parasites are one of the biggest and most preventable causes of cancer worldwide," lead authors Catherine de Martel and Martyn Plummer, from the International Agency for Research on Cancer in Lyon, France, said in a journal news release. "Application of existing public-health methods for infection prevention – such as vaccination, safer injection practice or antimicrobial treatments – ... Read more

Type of Bacteria May Be Linked to Diabetes

Posted 14 Mar 2012 by Drugs.com

WEDNESDAY, March 14 – There may be a link between H. pylori bacteria and type 2 diabetes in adults, according to a new study. In some people, an H. pylori infection of the stomach acquired in early childhood becomes persistent and can lead to ulcers in the stomach and small intestine. These bacteria have also been associated with an increased risk of stomach cancer. In this study, researchers analyzed data from people who took part in two U.S. National Health and Nutrition Surveys and found that the presence of H. pylori bacteria was consistently associated with elevated levels of glycosylated hemoglobin (HbA1c), an indicator of blood glucose levels and diabetes. This association was strongest in obese people, according to the study published March 14 in the Journal of Infectious Diseases. H. pylori may affect the levels of two stomach hormones that help regulate blood glucose, New ... Read more

Children Now Eligible for Screening Test for Bacterium

Posted 24 Feb 2012 by Drugs.com

FRIDAY, Feb. 24 – The U.S. Food and Drug Administration has expanded approval for a breath test that screens for a common ulcer-causing germ, to include children aged 3 years to 17. The Helicobacter pylori bacterium causes stomach inflammation (gastritis) and ulcers, and increases an infected person's risk of gastric cancer and a certain form of lymphoma. In a news release, the FDA said the BreathTak UBT test, approved for adults in 1996, is now sanctioned for children. The U.S. Centers for Disease Control and Prevention estimates that more than two-thirds of the world's population is infected with the bacterium, abbreviated H. pylori, but most infected people never have symptoms, the FDA said. The BreathTek UBT test was newly approved based on results from a multi-location clinical trial involving 176 children, the agency said. The test is produced by Otsuka America Pharmaceutical, ...

Stomach Cancer on the Rise Among Young, White Adults

Posted 4 May 2010 by Drugs.com

TUESDAY, May 4 – While rates of lower stomach cancer continue to decline for most groups in the United States, a new study finds that among young, white men and women the rate is increasing. The main cause of lower stomach cancer is infection with the bacteria Helicobacter pylori, while cancer in the upper stomach is often caused by acid reflux. Most stomach cancers are found in those aged 65 and older. In the United States, blacks, Asian Americans and Hispanics have the highest rates of stomach cancer, according to the researchers. "We confirmed what had been previously understood about gastric cancer, that in most groups it has been declining over the last 30 years," said lead researcher Dr. Charles Rabkin, a senior investigator at the U.S. National Cancer Institute. "We found one exception to that trend, which was that young, white Americans, ages 25 to 39, actually had increasing ... Read more

Health Tip: Warning Signs of Peptic Ulcer

Posted 27 Mar 2009 by Drugs.com

-- A peptic ulcer is a sore that occurs in the lining of the stomach or small intestine. A bacterium, called H. pylori, causes the sore to form. While the foods you eat don't cause peptic ulcers, foods can aggravate these sores. Peptic ulcers can be treated with antibiotics and acid-reducing medications. The National Digestive Diseases Information Clearinghouse lists these common warning signs of a peptic ulcer: Dull pain in the abdomen. Abdominal pain that fluctuates, but often occurs on an empty stomach or several hours after a meal. Abdominal pain that subsides after eating or taking antacid medications. Loss of weight and lack of appetite. Nausea or vomiting. Feeling bloated or frequent burping. Read more

New Yogurt May Ease Stomach Ulcers

Posted 23 Mar 2009 by Drugs.com

MONDAY, March 23 – A new type of yogurt available in some Pacific Rim countries appears to help prevent and fight ulcers and gastritis, according to Japanese researchers. The finding came from a study involving 42 people who had tested positive for the ulcer-causing bacteria Helicobacter pylori (H. pylori). They consumed two cups a day of regular yogurt or yogurt fortified with the antibody IgY-urease. By comparison, people who'd eaten the fortified yogurt had lower levels of urea, a urease byproduct, when retested a month later. That indicated less bacterial activity, according to the researchers, who were to present their finding March 22 at a meeting of the American Chemical Society in Salt Lake City. "With this new yogurt, people can now enjoy the taste of yogurt while preventing or eliminating the bacteria that cause stomach ulcers," study coordinator Hajime Hatta, a chemist at ... Read more
