Although it is important to review 13 years after the original presentation suggested that be aware of the possible clustering of autoimmune diseases in the immunological picture (raised dsDNA but normal ANF, the same person, it is more important to consider gluten neutropenia, high ESR) in combination with the gastro- sensitivity in the differential diagnosis of clinical scenarios intestinal symptoms and persistent headache might be such as those described above.

Immunological tests showed spectrum of gluten sensitivity may be easily and cost that she was positive for IgG and IgA antigliadin antibodies effectively undertaken by measuring circulating antigliadin and had the HLA typing DQ2.

Failure to do so may not only deprive the patient of the correct diagnosis and treatment(gluten-free diet) but also result in the unnecessary use of long term immunosuppressive drugs, with their associatedmorbidity.
