Henoch-Schonlein purpura (HSP) is a disease involving inflammation of small blood vessels. It most commonly occurs in children. The inflammation causes blood vessels in the skin, intestines, kidneys, and joints to start leaking.The main symptom is a rash with numerous small bruises, which have a raised appearance, over the legs or buttocks.
Henoch-Schonlein purpura is a small vessel vacuities in which complexes of immunoglobulin A (IgA) and complement component 3 (C3) are deposited on arterioles, capillaries, and venules. As with IgA nephropathy, serum levels of IgA are high in HSP and there are identical findings on renal biopsy. A diagnosis of Henoch-Schonlein purpura is fairly easy to make if the classic rash, joint pain and gastrointestinal symptoms are present. If some of these signs and symptoms are missing, the following tests have to be done lab testes (blood and urine tests), biopsies, and imaging tests.
Henoch-Schonlein purpura usually improves on its own within a month with no lasting ill effects. Bed rest, plenty of fluids and over-the-counter pain relievers may help.In Henoch-Schonlein purpura, some of the body's small blood vessels become inflamed, which can cause bleeding in the skin, joints, abdomen and kidneys.
We analysed 79 episodes of Henoch-Schonlein purpura in children. Skin manifestations were present in all cases, abdominal symptoms in 51.9%, arthritis or arthralgia in 41.8% and nephritis in 34.2% of the episodes. Skin rash and haematuria with proteinuria were the longest-lasting symptoms. Skin lesions persisted longer in case of disease relapses (p < 0.05). Typically Henoch-Schonlein purpura is a benign, self-limiting disease.
