Dermatitis herpetiformis is characterized as a stinging, itchy, blistering skin rash that develops once the skin reacts to the presence of gluten antibodies that circulate in the system. The condition is also called as “gluten rash” since it occurs along with celiac disease.
Gluten is a protein present in barley, wheat and rye. When an individual has celiac disease, the body reacts to the protein as a threat to the small intestines. If an individual has dermatitis herpetiformis, the immune system attacks the skin after gluten has been ingested. Even though this skin issue can develop on any part of the body, it frequently occurs in the knees, elbows, lower back, buttocks and back of the neck. In most circumstances, it is considered as one of the itchiest skin issues one can experience.
Symptoms
Individuals with dermatitis herpetiformis typically end up with rashes in the same area every time. The rash might appear continuous or can come and go depending on the exposure to gluten.
Prior to the actual break out of the rash, the skin can be itchy in that area or feel as if it is burning. Take note that the rash typically includes reddened skin along with several pimple-like bumps with clear liquid.
In most cases, the bumps can take several days to heal and once they do, the bumps leave behind small-sized purple marks that can last for weeks or even months. Those who have long-term dermatitis herpetiformis have unceasingly irritated, purple-dotted skin where the rash develops.
Who are at risk?
Dermatitis herpetiformis is quite common among men. The skin issue is believed to be uncommon in children younger than 10 years old, but based on latest studies, it can occur in younger children.
Always bear in mind that the rash often manifests in the teenage years, 20s or 30s and can go into a state of remission even if the individual sticks with a gluten-free diet.
Diagnosis
This condition is diagnosed via a skin biopsy procedure that assesses for the presence of specific deposits of antibodies under the skin. The dermatologist will take a small sample of the skin in the clinic.
It is vital to look for a dermatologist who is well-informed regarding the condition to carry out the biopsy. It is vital to sample the skin next to an active lesion or there is a risk of missing the telltale antibodies.
Treatment
Even though a medication called dapsone can provide initial relief from the itchiness linked with dermatitis herpetiformis, it has its share of long-term side effects. With this in mind, the only long-term treatment to manage the condition is to stick with a gluten-free diet.
Managing the condition with diet can be difficult, but it is worth it in order to eliminate the constant itchiness. If the rash is controlled and progresses into a state of cutback, any upcoming outbreaks that might occur are less severe.
