HSP usually affects children from two to 10 years of age, but it can happen in anyone. HSP itself is not contagious, but the infection that has triggered HSP may be contagious. There is no known way to prevent HSP.
How does HSP spread?
It might be triggered by bacterial or viral infections, medicines, insect bites, vaccinations or exposure to chemicals or cold weather. You may catch an infection that caused someone’s immune system to respond with HSP, but HSP itself isn’t contagious.
How do you catch HSP?
HSP is an autoimmune disorder. This is when the body’s immune system attacks the body’s own cells and organs. With HSP, this immune response may be caused by an upper respiratory tract infection. Other immune triggers may include an allergic reaction, medicine, injury, or being out in cold weather.
Is HSP a lifelong disease?
In most children, the symptoms and signs of HSP go away within one month, though some children will have problems for three months or even longer. The purpura on the skin disappears – and usually does not leave any scars – and the joint pain and tummy pain go away. This is called remission.
How serious is HSP?
The most serious complication of Henoch-Schonlein purpura is kidney damage. This risk is greater in adults than in children. Occasionally the damage is severe enough that dialysis or a kidney transplant is needed. Bowel obstruction.
Does HSP go away on its own?
Henoch-Schonlein purpura usually goes away on its own within a month with no lasting ill effects. Rest, plenty of fluids and over-the-counter pain relievers may help with symptoms.
How can HSP be prevented?
HSP can be prevented only to the extent that one minimizes exposure to viruses and certain drugs that could cause the abnormal immune response. As it is impossible to know who will get HSP, it is not possible to actually prevent it.
What causes HSP flare ups?
The exact cause of HSP is not fully understood, although research demonstrates that it is related to an abnormal response by the immune system or, in some rare cases, an extreme allergic reaction to certain offending substances (e.g., foods or drugs).
Can HSP come back years later?
Outlook. Most children with Henoch-Schönlein purpura will recover completely without long-term consequences. About a third of children with HSP will experience a recurrence of symptoms within the first year after disease onset.
