“…Indeed, a prospective study of the aetiology of LE in 100 patients estimated that at least 16% of patients with this condition may actually have CD [11]. However, a more recent Spanish prospective study of 90 consecutive patients with LE and clinical symptoms of CD reached a final diagnosis of gluten-sensitive enteropathy (GSE), alone or associated with Helicobacter pylori (HP) infection, in 43% of patients [12]. In addition to gluten sensitivity, LE may be related to non-steroidal anti-inflammatory drug (NSAID) intake, intolerance to non-gluten food protein (for example, cow’s milk, eggs, peanuts, soya), autoimmune disorders (for example, thyroiditis, type I diabetes, rheumatoid arthritis, psoriasis, multiple sclerosis, systemic lupus erythematosus), inflammatory and infectious intestinal tract disorders (for example, Crohn’s disease, bacterial overgrowth, HP, tropical sprue, and Giardia lamblia , Cryptosporidium and viral infections), and T-cell intestinal lymphoma [13,14].…”
