Dermatitis herpetiformis (DH) or Duhring's Disease, is a skin disorder often associated with celiac disease. It is a chronic, extremely itchy rash consisting of papules and vesicles. Dermatitis herpetiformis is associated with sensitivity of the intestine to gluten in the diet (celiac sprue).
Dermatitis herpetiformis usually begins in the twenties, though children may sometimes be affected. It is seen in both men and women. Though the cause of the rash is unknown, dermatitis herpetiformis is frequently associated with gluten (a protein found in cereals) sensitivity in the small bowel.

[edit] Symptoms
Dermatitis herpetiformis breakouts are usually extremely itchy. In many people the vesicles or papules appear on the elbows, knees, back, and buttocks (pressure points). It may also present as a patch of red skin with little water blisters scattered about. It is a systemic condition; the unpredictable skin rash may appear or be exacerbated by any irritation such as dry skin, scratching or clothing that is rough or scratchy. The fact that the rash is most prevalent at pressure points (where clothing rubs the most) may be why the symptoms sometimes appear to be symmetrical.
[edit] Signs and tests
A skin biopsy and direct immunofluorescence test of the skin are performed in most cases. Your doctor may additionally recommend a biopsy of the intestines.
[edit] Treatment
Dapsone, an antibiotic, may help the majority of patients.
A strict gluten-free diet will also be recommended to help control the disease. Adherence to this diet may eliminate the need for medications and prevent later complications.
[edit] Social impact
Lifelong diet The lifelong diet can be difficult and socially troublesome, especially in young patients, but it is crucial in order to avoid serious health consequences. Teenagers in particular occasionally rebel against the dietary strictures and suffer relapses or complications as a result. The widespread use of wheat byproducts in prepared food, soups and sauces can make dining out problematic. This is especially true in the United States, where dermatitis herpetiformis disease is less widely-known among the wider population than it is in Europe. However, certain types of restaurant (e.g., Japanese, Thai, Indian, and Latin American) already offer a wide range of gluten-free menu options, and many major restaurant chains have responded to growing awareness of celiac disease (and by default dermatitis herpetiformis) by posting information about the gluten content of their menu items on their websites.
It is important for people to understand that one does not "get over" dermatitis herpetiformis ; it is present for life. As coeliac disease has become better understood, the availability of gluten-free replacements for everyday treats such as muffins, bagels, pasta and the like has continually improved, as has their quality. This has also benefited those with dermatitis herpetiformis.
It is easy for people to think they have removed all gluten from their diet, but to continue to consume one or two products that they do not associate with gluten. For example, to eat only gluten-free foods but to continue to drink beer may easily make all that hard work useless. However, even this problem may now be overcome and there are many specialist brews around the world that may be described as gluten free beer.
However, the case of beer raises the main problem of dermatitis herpetiformis and coeliac disease: while the diet is strict and the effects of the disease are serious, the main symptom of the disease can be social isolation with those with Dermatitis herpetiformis afraid to become involved in normal social life. Parties can be difficult, weddings and funerals hard, holidays awkward, a meal out a nightmare, travel is made more stressful, and even the trip to a bar or pub one that requires the individual to be constantly aware of the disease. It is too easy for the coeliacs and those with dermatitis herpetiformis to withdraw from these normal activities, and many people with these complaints are working to create normal activities where they can forget the problem. It is important for newly diagnosed with either dermatitis herpetiformis or coeliacs to ensure that they do get involved in social activities and are not afraid to "make a fuss".
[edit] Religious Issues
The Eucharist: The Christian sacrament of the Eucharist presents a unique challenge for Christian sufferers of dermatitis herpetiformis or coeliac disease.
In its classical form, the bread and/or communion wafers have traditionally contained wheat flour, and therefore gluten. Coeliacs and those with dermatitis herpetiformis are therefore presented with a choice between denying themselves a central part of their religious practice or placing themselves at risk of serious illness. In response to this, some makers of communion wafers have begun making gluten-free versions (usually made of rice), which are now widely available. Many churches permit (or have no official policy on) use of these wafers, while other churches do not allow them.
In particular, Roman Catholic doctrine requires that the Eucharistic host (the communion wafer) must contain at least some unleavened wheat, as did the bread served at the Last Supper. The Catholic Church has approved the use of low-gluten wafers, but even these are not gluten-free. Some Catholic sufferers have requested permission to use rice wafers; these petitions have so far been denied.
However, official Roman Catholic doctrine is that a Catholic may validly receive communion by consuming a communion wafer and/or the consecrated wine. The Council of Trent decreed that taking either wine or wafer qualifies as a valid Communion:
"For we do not receive in the Sacred Host one part of Christ and in the Chalice the other, as though our reception of the totality depended upon our partaking of both forms; on the contrary, under the appearance of bread alone, as well as under the appearance of wine alone, we receive Christ whole and entire (cf. Council of Trent, Sess. XIII, can. iii). Therefore, any Catholic can receive the Eucharist in the 'fullness of the sacrament' (Catechism, Section 1390) simply in a sip of consecrated wine (even an approved low-alcohol wine); even those who cannot safely consume wheat (or indeed, any other grain) can safely partake of the Eucharist."
The matter has been controversial, however, and on August 22, 1994, the Congregation for the Doctrine of the Faith apparently banned those with coeliacs and dermatitis herpetiformis from the priesthood stating, "Given the centrality of the celebration of the Eucharist in the life of the priest, candidates for the priesthood who are affected by celiac disease or suffer from alcoholism or similar conditions may not be admitted to holy orders." After considerable upset and debate, the congregation softened the ruling on July 24, 2003 to "Given the centrality of the celebration of the Eucharist in the life of a priest, one must proceed with great caution before admitting to Holy Orders those candidates unable to ingest gluten or alcohol without serious harm,".
Eastern Orthodox Position: The Eastern Orthodox Church also requires that the bread used at the Eucharist be made with wheat flour; here the bread is leavened with yeast. In the Orthodox practice, the consecrated bread and wine are given together from a chalice with a spoon. Some Orthodox sufferers have been able to receive communion simply by having the priest take only wine in the spoon; others, more sensitive to wheat, have had to have some of the wine set aside before the bread is added to the chalice. This latter case is extremely unusual, and is strictly speaking only permissible with the blessing of the diocesan bishop. While the Orthodox do not have such an explicit rationale as the Roman Catholic Church, their general understanding is that, in the case of exceptions made for the sake of Economy, the Holy Spirit makes up whatever is lacking.
Coeliacs, dermatitis herpetiformis, and Passover The Jewish festival of Pesach (Passover) may present problems with its obligation to eat matzo. Matzo is normally made from wheat or other gluten-containing grains. Oat matzo is now available, however. Many products prepared for Passover are also non-gebrokts, which means they are free of wheat, barley, spelt, oats, and rye. Potato starch is the primary starch used to replace the grains. These products make it easier to participate in Passover.
[edit] Specialist breads, pastas, and beer
Although these diseases may tend to isolate individuals with the complaint, the situation is becoming less difficult year by year. Manufacturers are now making a wide range of very acceptable breads, and some pastas (notoriously horrible in the past) are virtually indistinguishable from "normal" pasta. Restaurants are beginning to offer gluten free menus and are recognising the size of the market that is largely not catered for. Coeliacs and those with dermatitis herpetiformis should not be afraid to ask establishments how they can cater for them. Where the question has been asked repeatedly, the proprietors tend to recognise the need, and become aware of the revenue that is lost where they do not provide a full range of products.
In many ways beer seems to be the hardest gluten free product to "get right". However, gluten free beer is now available and there is now a range of ales, beers, and lagers to choose from. Around the world standards of "gluten free" vary. For example, while in the United Kingdom a beer with less than 20 parts per million gluten (20ppm) is "gluten free", in Australia it is not possible to describe any product as such if any gluten can be detected at all. Similarly, some "gluten free" breads can contain low levels of gluten in one country, in another they would contravene labelling or food standards legislation.
However, while large scale commercial beers are out of the question for those who cannot consume gluten[1] [2] [3] (regardless of the sometimes misleading advice on some brewery websites), it is likely that most people with dermatitis herpetiformis coeliacs will be able to drink beer at under 20ppm (in moderation) without causing themselves any harm. It is important, however, for consumers of all "low gluten" foods and beverages to tell their consultant, and to ensure that even if the obvious symptoms are absent, there are no other negative effects continuing that they are unaware of.
However, the development of a range of gluten free beers is an example of those who cannot consume gluten "working together to socialize normally and avoid isolation caused by their special dietary needs. It also represents part of the return to a ‘normal’ life"[4].
