This guideline presents recommendations for the management of coeliac disease (CD) and other gluten-related disorders both in adults children. There has been a substantial increase prevalence CD over last 50 years many patients remain undiagnosed. Diagnostic testing, including serology biopsy, should be performed on gluten-containing diet. The diagnosis is based combination clinical, serological histopathological data. In group children may made without biopsy if strict criteria are...

Coeliac disease may be regarded as refractory (RCD) when symptoms persist or recur despite strict adherence to a gluten-free diet. RCD subdivided into types I and II with phenotypically normal aberrant intraepithelial T-cell population, respectively. seems respond well azathioprine/prednisone therapy. is usually resistant any known therapy transition enteropathy-associated lymphoma (EATL) common.To provide further insight the development of EATL, by reporting on long-term survival risk EATL...

AIM:To evaluate cladribine [2-chlorodeoxyadenosine (2-CdA)] therapy in refractory celiac disease (RCD) Ⅱ. METHODS:An open-label cohort-study of RCD Ⅱ patients treated with 2-CdA was performed between 2000 and 2010.Survival rate, enteropathy associated T-cell lymphoma (EATL) occurrence, clinical course, histological immunological response rates were evaluated. RESULTS:Overall, 32 included a median follow-up 31 mo.Eighteen responded well to 2-CdA.Patients responsive had statistically...

Refractory coeliac disease (RCD) is being currently defined as persisting or recurring villous atrophy with crypt hyperplasia and increased intra-epithelial lymphocytes in spite of a strict gluten-free diet for more than 12 months when severe symptoms necessitate intervention independently the duration dietary therapy. Two categories RCD are recognized: type I without aberrant T cells II detected by immunophenotyping intestinal mucosa. In contrast to patients high percentage cells, seem...
