How many cases of Henoch-Schönlein purpura are there?
HSP is the most common form of vasculitis in children, with an annual incidence on the order of 140 cases/million persons.
Can you get Henoch-Schönlein purpura twice?
About one third of children diagnosed with Henoch-Schönlein purpura will develop recurrent symptoms of Henoch-Schönlein purpura, although most recurrent episodes are less severe than the initial episode. However, recurrent episodes of Henoch-Schönlein purpura can last up to a year after the initial diagnosis.
Is Henoch-Schönlein purpura serious?
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.
Can HSP last forever?
For about two-thirds of children, all symptoms will be gone in two to four weeks. For the last one-third of children, symptoms are gone in one to three months. Serious complications of HSP are rare, but it is very important to follow up with your child’s doctor.
What causes HSP to flare up?
HSP is an autoimmune disease that is often triggered by an upper respiratory infection. Symptoms include a rash caused by bleeding under the skin, arthritis, belly pain, and kidney disease.
What causes HSP relapse?
Our results revealed that renal involvement, underlying allergic rhinitis, and steroid treatment for > 10 days were risk factors for HSP recurrence in children, regardless of age, sex, and income levels.
Can HSP affect the brain?
Inflammatory changes associated with HSP can also develop in the joints, kidneys, digestive system, and, in rare cases, the brain and spinal cord (central nervous system). In one form of the disorder, termed Schönlein’s purpura, the skin and joints are affected but the gastrointestinal tract is not.
Is HSP immunocompromised?
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 Henoch-Schönlein purpura hereditary?
However, while genes may increase the risk of developing the disease (and in some cases more than one family member has HSP), the disease itself is not inherited.
Can Covid cause IgA vasculitis?
Mucosal infections result in an upregulation of IL‐6 as in COVID‐19, which might trigger Gd‐IgA1 development and subsequent renal damage. 8 This might explain the hypothesis of severe COVID‐19 to be IgA mediated disease (related to IgA deposition and vasculitis) including IgA nephritis.
