But some celiacs will have just that profile, especially if they have IgA def. A simple test that it may be possible to do on the residual serum already taken. If there is IgA def. If there is no IGA def, another approach is to obtain a skin biopsy for DH, this is less of a deal that an intestinal biopsy and if the correct staining and biopsy preparation is done then it can reliably identify intestinal gluten sensitivity if the patient has dermatitis herpetiformis. Celiac disease is defined by a combination of damage to the gut and a subsequent improvement with a gluten free diet.
Celiac disease is a definite condition with a definite treatment.
The other entities if they exist it is not clear what should be done about those. I do not think it is standard practice to advocate less that a gluten free diet for celiac disease. Not reputable authority on the disease suggests that is a reasonable approach. The consequences of having some gluten in the diet in a celiac does leave them open to continued or new complications and continued ill health. The diet, while challenging, can be and is followed by the vast majority of adult patients that I seem with very rare problems.
