Dr. Ludvigsson and a team of colleagues compared the risk of tuberculosis in more than 4000 patients with celiac disease to that of 69,000 matched individuals in a general population-based study.
The study showed the presence of celiac disease corresponded to about a 3-to-4 times greater risk of subsequent tuberculosis. Similar results were found when the study population was grouped by their gender and age at the time of diagnosis for celiac.
The researchers concluded that celiac disease could affect the action of tuberculosis medication.
Further studies are likely warranted, as the study involved a fairly small number of cases, and only 24 celiac patients had contracted tuberculosis.
Subsequent confirmation of these findings would likely warrant making it standard practice to do serological testing for celiac disease in tuberculosis patients with gastrointestinal symptoms or with apparent drug resistance.
