Can strep cause vasculitis?
Streptococcus pyogenes can cause different immune mediated syndromes including vasculitis and IgAV.
What virus causes 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.
Is HSP viral or bacterial?
Henoch-Schönlein purpura (HSP) is the most common form of childhood vasculitis. Various viral and bacterial infections, drugs, vaccines, food allergy and even insect bites have been considered as triggering factors in pathogenesis of HSP.
Is HSP 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.
Is HSP vasculitis contagious?
Its exact cause is unknown. 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.
What is schonlein Henoch vasculitis?
IgA vasculitis (also known as Henoch-Schönlein purpura) is an inflammation of the small blood vessels in the skin, gastrointestinal tract and the kidneys. Symptoms include skin rash and joint pain. Diagnosis and treatment are discussed.
Does HSP ever go away?
Most of the time, HSP improves and goes away completely within a month. Sometimes HSP relapses; this is more common when a child’s kidneys are involved. If HSP does come back, it is usually less severe than the first time.
Can HSP be fatal?
The rash is present in all cases of HSP. Other accompanying symptoms can include abdominal pain, nausea and vomiting, arthritis, and blood in the urine. Kidney damage is the most common and most serious long-term complication. Although death from HSP is rare, kidney disease is the leading cause.
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.
Can strep cause HSP?
HSP affects people of all ages, but is most common in young children, and it often occurs after an infection such as a cold or strep throat.
Can HSP cause kidney damage?
There is no medicine to treat HSP, and treatments for the disease involve treating the symptoms, like the swelling, stomach pain, and arthritis. Most people recover fully from HSP without complications, but it can lead to chronic kidney disease and kidney failure over time.
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. Doctors don’t know how to prevent HSP yet.
