Q: What is silent celiac disease?
In 2013 a multidisciplinary task force of 16 physicians from seven countries published an article evaluating the numerous celiac disease (CD) related terms that exist in the literature. The team determined that “silent CD” is equivalent to “asymptomatic CD.” Use of the term silent CD is now discouraged.1
So, let’s take a look at asymptomatic CD.
“Individuals with asymptomatic CD do not manifest any symptoms commonly associated with CD and have no symptoms that respond to gluten withdrawal, even in response to direct questioning. These patients are often diagnosed through testing of populations enrolled in screening programs or in case-finding strategies for detecting CD in patients with disorders that are associated with a high risk for CD,”1 such as type 1 diabetes and thyroid disease.
There’s another similar term – subclinical CD. Subclinical CD has often been used interchangeably with silent CD and its definition has changed over time.
The task force specified subclinical CD to be” disease that is below the threshold of clinical detection without signs or symptoms sufficient to trigger CD testing in routine practice. These patients may have clinical or laboratory signs (iron deficiency anemia, abnormalities in liver function tests, [dental] enamel defects, incidental endoscopic features, osteoporosis, etc.) but no symptoms.”1 The main difference I can see between asymptomatic CD and subclinical CD is that patients with subclinical CD may often recognize minor symptoms, such as fatigue only after starting on a gluten-free diet.2
Celiac disease exists along a continuum from very mild to severe. Patients with asymptomatic CD or subclinical CD are generally identified due to a gastroenterologist’s increased awareness of CD during an endoscopy performed for other reasons or incidental testing of celiac serology (blood work) . These patients will usually display the characteristic damage to the lining of the small intestine without the classic clinical symptoms.2
