In a recent study published in the British Medical Journal, researchers found that blood tests and a history of patient symptoms might be all that’s needed to diagnose the majority of individuals with celiac disease. Until now, a diagnosis required a biopsy of the intestinal wall.
It is estimated that celiac disease (caused by an autoimmune reaction to wheat gluten) remains undiagnosed in a whopping 85% of cases. This may be due to the fact that symptoms are often non-specific (diarrhea and constipation, fatigue, anemia, tooth enamel defects, weight loss, and dry skin are some of the symptoms).
The researchers report:
We devised and evaluated a clinical decision tool that used a combination of pre-endoscopy serological testing (for tissue transglutaminase antibodies) and assessment of symptoms to identify patients with coeliac disease. This decision tool might help increase the detection of coeliac disease in patients attending for gastroscopy without the need to perform routine duodenal biopsy.
As efforts are underway to increase awareness in the primary care community about the disease, it is good to know that diagnosis may no longer require an invasive test!
