Chronic PPI Use and Asthma

Chronic PPI Use and Asthma

New research shows that prolonged use of proton pump inhibitors (PPI’s) can increase the risk for developing asthma.  PPI’s are the “drugs of choice” for esophageal reflux, gastritis and gastric ulcers.  But their long-term use impacts the gut microbiome which in turn can cause immune dysregulation.  It is this “tilting” of immune function that increases the risk for asthma.  Prolonged use of PPI’s by women during pregnancy also increases the risk for their child to develop asthma.  One strategy to…

Cross Reactive Epitopes & Food Allergy

Cross Reactive Epitopes & Food Allergy

A recent article in the Journal of Allergy and Clinical Immunology provided an update on our understanding of cross reactivity.  First by way of definition an epitope is a discreet (usually small) portion of a molecule that is the binding target of an antibody.  In the case of allergic problems, the antibody is IgE.  By way of example think of distinguishing features that help you identify a car:  the Mercedes Star and the Dodge Ram.  Allergy is directed at this…

Dear Dr. K;

Dear Dr. K;

I’ve seen you and multiple other doctors for what has been called unexplained chronic cough.  Now I’ve read about the new drug Gefapixant.  Do you think I’m a candidate? My answer is a qualified yes. But before I continue my answer let me first give a summary of your own situation that might be of help to other kindred spirits.  Your cough is called “unexplained” because despite our best efforts the medical specialists you’ve seen have failed to find a…

Dear Dr. K;  I read something that indicated chronic sinusitis can predispose to stroke.  It scared me.  Is it true? 

Dear Dr. K;  I read something that indicated chronic sinusitis can predispose to stroke.  It scared me.  Is it true? 

The short answer to your question is yes. But, the best answer to your question is maybe.  First of all, it is important to know that vascular problems in general whether due to blockage from plaque or due to a clot have inflammation as a common denominator.  Whether you’re talking about a coronary artery or a carotid artery or an intracranial artery its arterial inflammation that sets the stage for the problem.  By way of example, its arterial inflammation that…

Bones and Alzheimer’s

Bones and Alzheimer’s

Whoever would have thought that bone health could impact the development of dementia?  Until I learned about new research in this regard, I wouldn’t have connected the two.  The operant word here is “health” and that is a function of exercise.  Now, if you’ve read these newsletters in the past you’re probably thinking; Oh boy, here comes another sermon on the value of exercise.  And guess what?  You’re right! The research connecting the two is from the fields of neuroscience…

The T(r)OOTH of the Matter

The T(r)OOTH of the Matter

By:  Sasha Klemawesch, MD During residency, we had a DDS come do a grand rounds lecture. During it, he advised not rinsing after brushing. I paid no heed to his recommendation at the time since the idea of not rinsing your mouth out after you brush your teeth seemed so bizarre and gross (also probably I was too busy passing notes w my coresident to listen all that closely to a dental lecture – snore!). The American zeitgeist writ large…

TEWL

TEWL

TEWL stands for trans epidermal water loss.  It is the “unperceived” loss of water through our skin, in distinction to the “perceived” loss of water when we sweat.  It is also sometimes called insensible water loss.  It has been known for quite some time that children and adults with eczema have a greater TEWL than normal, but the difference has never been carefully measured.  The Allergy and Asthma Proceedings recently published new research doing just that.  The measurements were adjusted…

PLE

PLE

PLE stands for protein losing enteropathy and was the subject of a review article in a recent issue of The New England Journal of Medicine. PLE is a syndrome not a specific disease and can occur for a wide variety of reasons.  The problem is caused by the loss of plasma proteins through the intestines (they “leak” out).  In general terms it is caused by illnesses that damage the intestinal lining or that block the intestinal lymphatic drainage. The resultant…

Zorro Returns

Zorro Returns

A recent issue of the New England Journal of Medicine had an editorial (not a research paper) titled “Strategic Masking to Protect Patients from all Respiratory Viral Infections”.   It was written by four Harvard physicians whose specialty is epidemiology and public health.  The authors preamble alludes to the understandable mask wearing pushback/mask use fatigue in both the general population and in healthcare workers.  That’s very understandable.  We are all sick of constraints.  But the focus of the article is with…

Ice Cream Therapy

Ice Cream Therapy

Finally, a medical therapy I can relate to.  I love ice cream.  Actually, it’s not a medical therapy, but a safe mechanism to “test the waters” in alpha-gal syndrome.  This newsletter has previously discussed this uncommon condition that unfortunately is becoming more common.  By way of reminder the syndrome is the new onset of anaphylaxis due to eating meat.  It is a strange condition in that the allergic symptoms occur suddenly (hives, swelling, throat constriction) but are delayed 3 to…
