Refractory celiac disease (RCD) affects patients who have failed to heal after 6-12 months of a strict gluten-free diet (GFD) and when other causes of symptoms (including malignancy) have been ruled out. It may also occur in patients who previously had responded to a long-term GFD. RCD may be categorized as RCD1 (normal immunophenotype) and RCD2 (aberrant immunophenotype). RCD1 usually responds to a continued GFD, nutritional support, and therapeutic agents such as corticosteroids. In contrast, clinical response in RCD2 is incomplete and prognosis is often poor. RCD (particularly RCD2) is associated with serious complications, such as ulcerative jejunitis and enteropathy-associated T-cell lymphoma (EATL). Strict clinical and laboratory criteria should be used to diagnose RCD and specialized tests for aberrancy and clonality should be interpreted in the context of their sensitivity and specificity. Adequate nutritional support and anti-inflammatory treatment may even allow patients with RCD2 to attain a clinical remission.

A percentage of celiac disease (CD) patients develop refractory type-2 disease (RCD2), a condition associated with increased risk of enteropathy-associated T-cell-lymphoma (EATL) and without therapeutic option. Therefore, we profiled the miRNome in series of peripheral T-cell lymphomas (PTCLs), CD, RCD1 or 2 and in the murine interleukin-15 (IL15)-transgenic (TG) model of RCD. The transcriptome was analyzed in 18 intestinal T-cell lymphomas (ITLs). Bioinformatics pipelines provided significant microRNA (miRNA) lists and predicted targets that were confirmed in a second set of patients. Our data show that ITLs have a unique miRNA profile with respect to other PTCLs. The c-MYC regulated miR-17/92 cluster distinguishes monomorphic epitheliotropic ITL (MEITL) from EATL and prognosticates EATL outcome. These miRNAs are decreased in IL15-TG mice upon Janus kinase (JAK) inhibition. The random forest algorithm identified a signature of 38 classifier miRNAs, among which, the miR-200 and miR-192/215 families were progressively lost in RCD2 and ITL-CD, whereas miR-17/92 and C19MC miRNAs were up-regulated. Accordingly, SMAD3, MDM2, c-Myc and activated-STAT3 were increased in RCD2 and EATL tissues while JAK inhibition in IL15-TG mice restored their levels to baseline. Our data suggest that miRNAs circuit supports activation of STAT3 and c-Myc oncogenic signaling in RCD2, thus contributing to lymphomagenesis. This novel understanding might pave the way to personalized medicine approaches for RCD and EATL.
