Anaphylactoid Purpura

What is anaphylactoid purpura?

Anaphylactoid purpura (also called Henoch-Schoenlein purpura) is an illness that can involve many different organs in the body.

Anaphylactoid purpura can occur with some or all of the following symptoms:

• Rash: The rash is often located on the buttocks and legs. The rash may first look like hives, but usually it changes to purplish or brownish bruises within 1 to 2 days. There is almost always some rash on the ankles.
• Painful swelling of the joints: The joints most often affected by pain are the knees and ankles. The joint pain may be severe enough to make your child unable or unwilling to walk.
• Abdominal pain: If your child has severe abdominal pain or blood in his or her stools, the doctor may need to do tests to rule out other, more serious causes of these symptoms.
• Fever.
• Blood in the urine.

What is the cause?

The cause of this illness is not completely understood. Researchers believe that there is some inflammation (swelling) in the blood vessels, which causes symptoms. The illness is often seen in children who have had a viral upper respiratory infection (a cold) a few weeks earlier. The antibodies produced by the child's body to fight the cold may contribute to development of the illness.

The older your child is, the more likely it is that he or she will experience the symptoms again. Your child will eventually get better on his or her own.

How can I take care of my child at home?

Do not use aspirin. Acetaminophen (for example, Tylenol) may help with the pain, but it will not relieve swelling and inflammation. Your child's dose of ibuprofen is ____ mg every 6 to 8 hours as needed for pain.

• Steroid medications
