Is There Really a Link between Asthma and Reflux?

By Scott Statman, MD

Peer Reviewed

There is little doubt that an association between asthma and gastroesophageal reflux disease (GERD) exists. However clinicians have debated the nature of this relationship for decades. Asthma and GERD are among the most common disorders encountered by physicians, with prevalence in the general population estimated at 8%1 and 10 to 20%2 respectively. Studies have shown that up to 80% of asthmatics have symptomatic GERD3 and that people with GERD are nearly1.2 times more likely to have asthma.4  This may …

A 48-year-old depressed male smoker with a bit of an alcohol problem presents to the emergency department with worsening fatigue, severe lower back pain, constipation, abdominal pain, and 4 days of coffee ground emesis.

This could be anything. Viral gastroenteritis? Perhaps. Food poisoning? Probably not. Upper GI bleed? Likely, given his alcohol use. You send off routine labs, and then are called for a critical value: his calcium is 13.8 mg/dL. The albumin is normal. Next, you check the …

Proton Pump Inhibitors: Acid Suppression with a Nutritional Cost

By Dana Zalkin

Peer Reviewed

In the late 1970s evidence began to emerge that a newly discovered pump, a H+/K+ ATPase in the gastric mucosa, was the final step in the process of acid secretion . With this discovery, further research demonstrated the ability to reduce gastric acid secretion by inhibiting these proton pumps . We now have drugs that do just that: the proton pump inhibitors (PPIs). Proton pump inhibitors have been used since 1989 to treat acid-related gastrointestinal disorders as well as in …

Proton Pump Inhibitors and Clostridium Difficile Infection

By Aaron Smith, MD

Peer Reviewed

First introduced in the late 1980s, proton pump inhibitors (PPIs) have revolutionized the treatment of gastric acid-related disorders and have been described as a miracle drug by patients and physicians alike. As is often the case with miracle drugs, however, long-term use of PPIs has led to unforeseen adverse effects. Chief among the purported side effects of PPI use is an association with Clostridium difficile infection (CDI). CDI, an enterocolitis that leads to voluminous and potentially fatal diarrhea, was …
