Heartburn, Indigestion & Protein Pump Inhibitors

I have seen multiple adult patients with intractable heartburn, reflux, indigestion and chest pressure all related to food and digestive enzymes kicking back up the esophagus from the stomach through a lax group of muscles known as the lower esophageal sphincter.  All these patients receive a fiber optic upper endoscopy (EGD) at some point and are observed and biopsied to eliminate the possibility of ulcers, cancer, gastric polyps, esophageal cancer, potential esophageal cancer and Helicobacter Pylori bacteria as the cause.

They are all treated with weight control suggestions, avoiding a host of foods, most of which are quite healthy from a cardiovascular standpoint plus limits on alcohol, elimination of tobacco and other indulgences of adults. We ask these patients to wear loose clothing at the waistline, avoid reclining for three hours after eating and take a host of medicines including proton pump inhibitors (PPI) such as Nexium, Protonix, Prilosec.  Drugs like Tagamet, Zantac (H2 Receptor Blockers), Tums, Rolaids are far less effective.

In recent years, numerous articles have appeared in medical journals stating that protein pump inhibitors, when taken regularly, can predispose to increased and early death, pneumonia and dementia.  A large review article from a prominent GI group in Boston, and published in the New England Journal of Medicine, tried to eloquently refute these claims but the doubt about long term safety lingers buoyed by numerous lay periodicals and online internet sites sensationalizing the down sides of these medicines.

To allay the patients fears, doctors and patients work together to try and stop the PPIs and substitute the older standbys like Tagamet and Zantac but they just don’t provide the symptom relief that the PPI’s do. Patient’s face the dilemma of taking the medicine that works best and incurring the potential risks or suffering.

In a recent edition of the journal Gastroenterology, Paul Moayyedi, MB ChB, PhD from McMaster University in Canada followed 17,000 patients for three years with half the group taking PPI’s. Those taking a PPI (Protonix) for three years had no more illness or adverse effects than those taking a placebo.  L. Cohen, MD, a reviewer at Mount Sinai School of Medicine in NY, concluded that the study provided strong evidence of the safety of PPIs for patients taking the drug for three consecutive years.

The controversy will continue. I am sure next week someone will produce data revealing some additional horrible consequences of taking these medications to relieve heartburn. It will ultimately come down to individual decisions about quality of life versus potential risks because the lifestyle changes necessary to control this problem are difficult for human beings to sustain over a long period of time.

Drinking Coffee, Lower Mortality

Over the years, the consumption of coffee and its relationship to your health has been controversial.  In my medical school, internship, and training years in the late 1970‘s, it was thought that consuming more than five caffeinated beverages per day was associated with an increased risk of pancreatic cancer. That relationship has since been disproved.

The May 17th issue of the New England Journal of Medicine published a study on coffee drinking that will certainly make coffee drinkers more comfortable with a consuming a “cup of Joe.” They looked at a National Institute of Health – AARP study that began 1995 and includes almost 230,000 men and 173,000 women. They found that coffee drinking was associated with many negative behaviors including cigarette smoking, less exercise, eating more red meat, and eating less fresh fruits and vegetables.  Upon initially looking at the data, coffee drinking was associated with an increased mortality. However, when researches removed the negative behaviors from the data, and looked at the people who drank coffee but didn’t smoke and exercised; they found a significant drop in the mortality of coffee drinkers. Over 13 years, men who drank 4-5 cups of coffee per day had a risk reduction of 12% while women had a risk reduction of 16%.

The risk reduction was considered “modest” by Neal Freedman, PhD of the National Cancer Institute.  Lona Sandon, RD (registered dietitian) of the UT Southwestern Medical Center in Dallas said, “Based on this study alone I would not tell people to start drinking more coffee to lower their risk of death.”   She felt individuals should “stop smoking, be more physically active, and eat fruits, veggies, whole grains and healthy fats…. A little coffee doesn’t appear to hurt.”  Cheryl Williams, RD, of Emory Heart and Vascular Center in Atlanta commented that “if you are not a coffee drinker, this study is not a good enough reason to start.”

The study seemed to show that with consumption of 4-5 cups of coffee per day your risk of death due to cardiovascular disease, respiratory disease, injuries and accidents, diabetes and infections decreased. Coffee consumption did not appear to protect against cancer-related deaths. The design of the study does not allow us the luxury of saying drinking coffee is the “cause” of an “effect” of lowered overall mortality, but does certainly hint at it.

What is clear is that coffee drinking does not appear to have an adverse effect on already healthy lifestyles, but will not protect an individual from the detrimental effects of smoking, poor dietary choices and inactivity.
