Is Better Testing Driving Higher Celiac Rates?

Celiac.com 01/14/2015 - Recent epidemiological studies show that celiac disease rates are still underestimated, both in Europe and in Mediterranean regions. But how is better testing impacting higher celiac numbers in Europe?

To get a clearer picture, a team of researchers recently set out to review the latest data on celiac rates and incidence in the European Union (EU) as of September 2014.

They assessed the celiac disease rates and cases by conducting a search of PubMed for papers in English using the key words "celiac disease", "celiac disease plus prevalence" (limits: 1990-2014), "incidence" (limits: 1970-2014), and "frequency", plus "in Europe". They conducted additional searches using the same key words plus the name of each European country.

The team included only prevalence data obtained by serology using anti-gliadin antibodies (AGA), EMA test, tTG test, and/or duodenal biopsy, and only studies that were retrospective and prospective, such as population-based, cross-sectional, case-control and cohort studies.

They found that the overall undiagnosed celiac population in EU is 0.5-1%, whereas the highest estimate reported in population-based studies is approximately 1%.

Considering data from different periods, incidence seems to range from 0.1 to 3.7/1000 live births in the child population and from 1.3 to 39/100,000/year in the adult population.

Interestingly, though perhaps unsurprisingly, the data show clear geographical variation in both cases and rates of celiac disease in various European countries.

They note a rising occurrence of celiac disease in recent decades in European countries, due partly to the advent of improved serological testing (tTG + EMA) and partly to increased awareness of its clinical presentation.

When I was sent for a blood test to diagnose celiac the guy at the lab asked which panel I was supposed to have as there were three different panels. Each one covering more and more expensive. He said the first and second panel covered most of it, so I went with that. I shudder to think that if I had only got the simple? first test, which came back negative, where I would be healthwise today. The second test was very high in Celiac markers and I started feeling better within days, although it seemed to take a year to feel fully recovered. People should get retested if they test negative but have a family history or still suspect they have celiac. And keep reminding us MSG is not gluten/does not contain gluten.

We are going to try to make our own this year, but I've seen some great gingerbread houses made out of graham crackers. There are plenty of gluten-free graham crackers out there--Pamela's are nice and sturdy for building! If you make your own, the nice thing is that you don't have to worry whethe...

Symptoms from many illnesses often overlap, so you can not diagnose celiac disease based on them (not to mention that there are over 200 possible symptoms). Best to get a simple blood test. Learn more about testing: http://www.cureceliacdisease.org/screening/

I have eaten the Southwest chicken salad at McDonald's many times, with the grilled chicken and no chips. I have celiac disease, and have no problems with this salad. It's a stand by for me when traveling.

Hi Lex, First step would be to eliminate celiac. Gluten is well established as the cause of celiac. If you eliminate celiac but still react to gluten foods then it becomes trickier. Non Celiac Gluten sensitivity NCGS is still not universally accepted and there are differing views on whe...
