Henoch-Schönlein purpura is a disease that causes small blood vessels in the body to become inflamed and leak. The primary symptom is a rash that looks like many small raised bruises. HSP can also affect the kidneys, digestive tract, and joints. HSP can occur any time in life, but it is most common in children between 2 and 6 years of age. Most people recover from HSP completely, though kidney damage is the most likely long-term complication. In adults, HSP can lead to chronic kidney disease (CKD) and kidney failure, described as end-stage renal disease when treated with blood-filtering treatments called dialysis or a kidney transplant.
Henoch-Schönlein purpura is caused by an abnormal immune system response in which the body’s immune system attacks the body’s own cells and organs. Usually, the immune system makes antibodies, or proteins, to protect the body from foreign substances such as bacteria or viruses. In HSP, these antibodies attack the blood vessels. The factors that cause this immune system response are not known. However, in 30 to 50 percent of cases, people have an upper respiratory tract infection, such as a cold, before getting HSP.
The symptoms of HSP include the following:
Rash. Leaking blood vessels in the skin cause a rash that looks like bruises or small red dots on the legs, arms, and buttocks. The rash may first look like hives and then change to look like bruises, and it may spread to the chest, back, and face. The rash does not disappear or turn pale when pressed.
Digestive tract problems. HSP can cause vomiting and abdominal pain, which can range from mild to severe. Blood may also appear in the stool, though severe bleeding is rare.
Arthritis. Pain and swelling can occur in the joints, usually in the knees and ankles and less frequently in the elbows and wrists.
Kidney involvement. Hematuria— blood in the urine—is a common sign that HSP has affected the kidneys. Proteinuria—large amounts of protein in the urine—or development of high blood pressure suggests more severe kidney problems.
Other symptoms. In some cases, boys with HSP develop swelling of the testicles. Symptoms affecting the central nervous system, such as seizures, and lungs, such as pneumonia, have been seen in rare cases.
