This guideline presents recommendations for the management of coeliac disease (CD) and other gluten-related disorders both in adults and children.
There has been a substantial increase in the prevalence of CD over the last 50 years and many patients remain undiagnosed. Diagnostic testing, including serology and biopsy should be performed on a glutencontaining diet.
The diagnosis of CD is based on a combination of clinical, serological and histopathological data. In a group of children the diagnosis may be made without biopsy if strict criteria are available.
The treatment for CD is primarily a gluten-free diet (GFD), which requires significant patient education, motivation, and follow-up. Slow-responsiveness occurs frequently, particularly in those diagnosed in  adulthood.
Persistent or recurring symptoms necessitate a review of the original diagnosis, exclude alternative diagnoses, confirm dietary adherence (dietary review and serology) and follow-up biopsy. In addition, evaluation to exclude complications of CD, such as refractory CD or lymphoma, should be performed. The guideline also deals with other gluten-related disorders, such as dermatitis herpetiformis, which is a cutaneous manifestation of CD characterized by granular IgA deposits in the dermal papillae. The skin lesions clear with gluten withdrawal. Also, less well-defined conditions such as non-coeliac gluten sensitivity (NCGS) and gluten-sensitive neurological manifestation, such as ataxia and have been addressed.
Newer therapeutic modalities for CD are being studied in clinical trials, but are not yet approved for use in practice.
