Heartburn Drugs May Raise Pneumonia Risk

An interesting topic was reported in Healthday, Monday, Dec. 20 (HealthDay News), by Jenifer Goodwin, about popular heartburn drugs, including proton pump inhibitors and histamine-2 receptor antagonists, that may raise the risk of pneumonia based on new research.

Researchers in Korea analyzed the results of 31 studies on heartburn drugs published between 1985 and 2009.

"Our results suggest that the use of acid suppressive drugs is associated with an increased risk of pneumonia," said Dr. Sang Min Park of the department of family medicine at Seoul National University Hospital in Korea.

"Patients should be cautious at overuse of acid-suppressive drugs, both high-dose and long duration," he added.

Sales of these enormously popular drugs -- the second best-selling category of medications worldwide -- reached nearly $27 billion in the United States in 2005, according to background information in the study, published Dec. 20 in CMAJ (Canadian Medical Association Journal).

Proton pump inhibitors (PPIs) reduce acid production in the stomach and are used to treat heartburn, gastroesophageal reflux disease (GERD) and gastric ulcers. They include omeprazole (Prilosec), lansoprazole (Prevacid) and esomeprazole (Nexium).

Histamine-2 receptor antagonists, often called H2 blockers, use a different mechanism to reduce stomach acid and include cimetidine (Tagamet), famotidine (Pepcid), nizatidine (Axid) and ranitidine (Zantac).

Dr. Park's meta-analysis combined the results of eight observational studies that found that taking PPIs increased the chances of developing pneumonia by 27 percent, while taking H2 blockers resulted in a 22 percent increased chance of pneumonia.

An analysis of 23 randomized clinical trials found people taking H2 blockers had a 22 percent increased chance of getting hospital-acquired pneumonia.

The normal acid of the stomach acts as a defense system in that the acid will kill certain harmful bacteria that may otherwise invade the pulmonary (lung) system and potentially lead to infection.

In addition to a lung infection, there has been a rise in the gastrointestinal infection, referred to as Clostridium difficle,as a result of chronic PPI use.

We must rethink the liberal use of acid lowering drugs and, in some cases, consider procedural therapy for reflux in an appropriately selected patient population.  

These recent revelations about long-term PPI therapy may explain the rising popularity of antireflux surgery, specifically with transoral incisionless fundoplication with the EsophyX TIF procedure.

GERD Affects Sleep and Next-Day Performance

Posted by Anthony Starpoli on Oct 23, 2010 9:36:00 AM

Gastroesophageal Reflux Disease or GERD is well-known to affect sleep patterns and an irregular sleep pattern can lead to poor performance in wake periods. Furthermore, there is a bidirectional relationship between sleep and GERD.  Poor sleep can lead to an exacerbation of GERD and GERD can disturb sleep.

The Not So Common Forms of Reflux

Posted by Anthony Starpoli on Oct 14, 2010 10:50:00 AM

Most people think of gastroesophageal reflux disease or GERD as the classic symptoms of heartburn or regurgitation.  Heartburn is often reported as a burning sensation below the breast bone and regurgitation is the effortless repeating or return of food material back up the esophagus (or food tube).  It is important not to mistake a chest pain complaint that may be cardiac in origin for reflux.  See your doctor if you have a new chest pain complaint, especially if you have cardiac disease risk factors such as a family history of heart disease, high cholesterol, obesity, or if you smoke.  Now, back to reflux troubles.
