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; however, IgA nephropathy has a predilection for young adults while HSP is more predominant among children.
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 biopsies, and imaging tests. Treatment: 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.
Statistics:Henoch-Schonlein purpura (HSP) in patients <18 years who were followed up at King Abdulaziz University Hospital, Jeddah over the last 12 years. We performed a retrospective chart review of the medical records of all patients diagnosed as HSP. During this period, only 29 cases were reported (15 males, 14 females), with the mean age at the diagnosis 7.5 years. 82% percent of the patients had joint involvement in the form of arthritis or arthralgia; 17.2% had no joint involvement.
