Heartburn Drugs May Cause Diarrhea
Drugs Stifle Body's Defense Against Diarrhea Bug
Dec. 20, 2005 -- Heartburn sufferers, listen up: Acid-fighting drugs might spell relief, but they could leave a less-welcome gift -- diarrhea.
People taking proton pump inhibitors and H2 blockers have greater risk of infection from a potentially dangerous diarrhea bug known as Clostridium difficile, or C-diff, reports researcher Sandra Dial, MD, MSc, a researcher at McGill University in Montreal. Her study appears in this week's issue of The Journal of the American Medical Association.
Proton pump inhibitors include Prilosec, Prevacid, and Nexium among others. H2 blockers include drugs such as Zantac, Pepcid, and Tagamet. These are the main medications offered to people suffering from stomach acid problems such as gastritis, GERD (acid reflux disease), or heartburn. They work to suppress stomach acid production which helps to alleviate discomfort. Sleeping With Heartburn Carries Cancer Risks.
Clostridium difficile is prevalent in the environment and especially in hospitals and nursing homes. Spores from C-diff enter our bodies through the mouth, which is the entryway for the gastrointestinal tract. Diarrhea caused by C-diff is a result of overgrowth of the C-diff bacteria in the colon, or large intestine. It has generally been associated with antibiotic use, which can kill "good" bacteria in the colon which keeps C-diff at bay. Infection has also been associated with stays in hospitals and nursing homes where it is easily passed to others.
The incidence and severity of diarrhea caused by C-diff has increased dramatically, according to recent data, writes Dial. Diarrhea caused by C-diff can be severe, with a cramping form of intestinal inflammation known as colitis.
"Clostridium-difficile-associated disease is becoming an important public health issue," writes Dial. Gastric (stomach) acid operates as a major defense mechanism against ingested bugs. But when people take gastric acid suppressors the stomach's normal acidity is lost, and this defense mechanism may become diminished, she explains.
Dial's study -- the largest study thus far of this risk factor -- looked at whether these drugs had any association with community-acquired C-diff infection. She and her colleagues examined data from 3 million patients of 400 general practioners in the U.K. from 1994 to 2004. There were 1,672 identified cases of C-diff, with numbers increasing from less than one per 100,000 in 1994 to 22 per 100,000 in 2004.
