Atopic Dermatitis

Overview

Definition

Eczema is a condition that makes the skin itchy and red. It lasts over a long period of time which can include flare ups.

Causes

Symptoms of eczema are caused by inflammation in the skin. It is not clear what causes this. Things that may play a role include:

  • Genetics
  • Environment
  • Allergies

Risk Factors

Things that may increase the risk of eczema:

  • Having asthma or allergies
  • Living in city or places with low humidity
  • Eczema or allergies in family members
  • Regular contact with things that irritate the skin such as:
    • Fabrics
    • Perfumes in soaps
    • Dust mites (common)
    • Rubber gloves for people sensitive to latex
  • Stress—scratching can be a habit with stress
  • Area is washed often
  • Scratching or rubbing of skin
  • Medicine that lowers the immune system
  • Excess weight or obesity

SymptomsandDiagnosis

Symptoms

Eczema may cause some of the following:

  • Dry, itchy skin (very common)
  • Red rashes on the cheeks, arms, and legs
  • Red, scaly skin
  • Thick, leathery skin
  • Small, raised bumps on the skin
  • Crusting, oozing, or cracking of the skin

Diagnosis

The doctor will ask about symptoms and health past. A physical exam will be done. The diagnosis is often made based on how the skin looks. Tests may be done to rule out other problems or to look for an infection.

Treatments

Treatment

Treatment can help to ease itching and redness. It may also reduce the number of flare ups. The medical team can also help to find what may be causing more irritation.

Scratching the skin can make symptoms worse and damage skin. Damaged skin will increase the risk of infection. Treatment can help to ease itchiness and protect the skin. Treatment steps may include:

Skin Care

Proper skin care may decrease injury to the area and allow the skin to heal. Steps to ease stress on skin include:

  • Avoid hot or long baths or showers.
  • Use mild, unscented bar soap or non-soap cleanser.
  • Do not scrub area. Air-dry or gently pat is better to dry skin.
  • Gentle moisturizers should be used after a shower when skin is still damp.
  • Treat skin infections right away.

Medications

Medicine may be needed to ease symptoms. Examples include:

  • Prescription creams and ointments. They can ease flare up and irritation of skin.
  • Prescription or over-the-counter antihistamines to help prevent itching.
  • Antibiotics to treat infection. It may be given as a cream or pill.
  • Pills to reduce inflammation of the skin.
  • Monoclonal antibody shots to reduce inflammation.

Phototherapy

Light therapy may be tried if other care is not helpful. This may include:

  • Treatment with ultraviolet light
  • Psoralen, a medicine used to make skin more sensitive to light therapy
