It can occur at any age but is usually seen in children, more often boys than girls.</p> <h3>More to Know</h3> <p>Although no one really knows what causes HSP, doctors do know that it occurs when the body's&nbsp;<a href="https://kidshealth.org/ws/RadyChildrens/en/parents/immune.html/">immune system</a>&nbsp;doesn't function as it should. HSP often happens after a bacterial or viral upper respiratory infection. Other possible triggers include certain medicines, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/insect-bite.html/">insect bites</a>, cold weather, and vaccinations.</p> <p>Signs and symptoms of HSP include a raised, reddish-purple rash, fever, stomach pain, bloody stools, blood in urine, and joint pain. HSP also can cause mild to severe kidney problems, so it&rsquo;s important to see a doctor if you suspect Henoch-Sch&ouml;lein purpura.</p> <p>With bed rest, increased fluid intake, and pain relievers, most people with HSP will see an improvement in their condition within a month. It is not unusual, however, to have mild recurrences.</p> <h3>Keep in Mind</h3> <p>Most people will recover fully from Henoch-Sch&ouml;lein purpura with no lingering effects. People whose kidneys are affected, however, will need to work with their doctor to prevent serious and even life-threatening complications.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
