Refractory Celiac Disease Successfully Treated With Azathioprine

Refractory celiac disease (CD) is a clinical diagnosis defined by the persistence of signs/symptoms, laboratory abnormalities or villous atrophy typical of CD despite strict adherence to a gluten-free diet for at least 6 - 12 months. It should be suspected when patients with CD fail to respond primarily or secondarily to a gluten-free diet, especially if there is significant weight loss. Differentiation between types is important both for management and predicting prognosis. Type I can be managed with mild immunosuppression with nutritional support. Type II requires strong immunosuppression like azathioprine. Recently, autologous stem cell transplantation has also been used to treat type II.
