Clinical characteristics at diagnosis of coeliac disease between the RCD patients and patients with uncomplicated disease were compared.</p> </sec> <sec id="apt12606-sec-0004" sec-type="section"> <title>Results</title> <p>The prevalence of RCD was 0.31% among diagnosed coeliac disease patients and 0.002% in the general population. Of the enrolled 44 RCD patients, 68% had type I and 23% type II; in 9% the type was undetermined. Comparing 886 patients with uncomplicated coeliac disease with these 44 patients that developed RCD later in life, the latter were significantly older (median 56 vs 44 years, <italic>P</italic> < 0.001), more often males (41% vs. 24%, <italic>P</italic> = 0.012) and seronegative (30% vs. 5%, <italic>P</italic> < 0.001) at the diagnosis of coeliac disease. Patients with evolving RCD had more severe symptoms at the diagnosis of coeliac disease, including weight loss in 36% (vs. 16%, <italic>P</italic> = 0.001) and diarrhoea in 54% (vs. 38%, <italic>P</italic> = 0.050).</p> </sec> <sec id="apt12606-sec-0005" sec-type="section"> <title>Conclusions</title> <p>Refractory coeliac disease is very rare in the general population. Patients of male gender, older age, severe symptoms or seronegativity at the diagnosis of coeliac disease are at risk of future refractory coeliac disease and should be followed up carefully.</p> </sec> </abstract>
