ANN ARBOR, Mich. – May 1, 2006 - For those who suffer from stomach ulcers, the daily routine of breakfast, lunch and dinner can be painful. A common cause of these ulcers, as well as other gastric malignancies, is a bacterium called Helicobacter pylori. For some, this infection can be persistent and difficult to treat.

Many approaches have been taken in an attempt to clear such infections, but with limited or unsuccessful outcomes. In a recent meta-analysis of therapies published in the April issue of The American Journal of Gastroenterology, Levofloxacin-based triple therapy was found to be better tolerated and more effective than bismuth-based quadruple therapy for patients with persistent H. pylori despite previous treatment attempts. Levofloxacin is commonly prescribed to treat such infections as pneumonia, bronchitis and urinary tract infections.

According to author William D. Chey, "Helicobacter pylori is a highly prevalent chronic infection with a worldwide prevalence of nearly 50% and U.S. prevalence of 20-40%." This bacterial infection is particularly difficult to treat because of its ability to adapt to the harsh environment in the stomach. The bacterium guards itself in the lining of the stomach, which prevents the body's natural defenses (Killer T Cells) from attacking it.

Levofloxacin-based triple therapy may offer an effective and safe treatment option for patients with persistent H. pylori infection, according to researchers. With so many people living with this infection, it has become increasingly important to achieve effective methods of treatment. Levofloxacin-based therapy may prove to be this method.
