The recurrence rate of Henoch-Schönlein purpura (HSP) is 2.7%–30%, with varied average intervals between the first and second episodes. Few studies have explored the incidence and risk factors for recurrent HSP.

HSP occasionally comes back, usually within a few months, and may need further treatment. A few children have long-term problems, especially when their kidneys are affected. They will need to be monitored and may need specialist treatment.

Most children with HSP fully recover within a month and have no long-term problems. Kids whose kidneys are affected will need to see a doctor for regular checkups to monitor kidney function. Some kids who have HSP get it again, usually a few months after the first episode.

Outlook. Most children with Henoch-Schönlein purpura will recover completely without long-term consequences. About a third of children with HSP will experience a recurrence of symptoms within the first year after disease onset.

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.

Lung involvement in HSP can be subclinical, is not uncommon in children and can result in interstitial lung disease with slight radiological signs and impaired gas exchange [7,8].

The exact cause of HSP is not fully understood, although research demonstrates that it is related to an abnormal response by the immune system or, in some rare cases, an extreme allergic reaction to certain offending substances (e.g., foods or drugs).

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.

HSP isn’t a disorder or a condition, but rather a personality trait that’s also known as sensory-processing sensitivity (SPS).

Your child can go back to school as soon as they feel well enough and are able to move about without too much pain. They may need to avoid exercise for a week or two if they have sore or swollen joints.

The four main characteristics of Henoch-Schonlein purpura include: Rash (purpura). Reddish-purple spots that look like bruises develop on the buttocks, legs and feet. The rash can also appear on the arms, face and trunk and may be worse in areas of pressure, such as the sock line and waistline.

Henoch-Schonlein purpura usually goes away on its own within a month with no lasting ill effects. Rest, plenty of fluids and over-the-counter pain relievers may help with symptoms.

Adults with HSP are more likely to have more severe disease compared to children. HSP usually ends after four to six weeks — sometimes with recurrence of symptoms over this period, but with no long-term consequences (recurrences are fairly common).

Because IgAV is a multisystem disease, consultations with the following specialists can be helpful in diagnosis and treatment: Dermatologist. Gastroenterologist. Nephrologist (particularly for assistance in determining if dialysis is indicated)

Psychogenic purpura, also known as Gardner-Diamond syndrome or autoerythrocyte sensitization syndrome, is a rare condition characterized by spontaneous development of painful edematous skin lesions progressing to ecchymosis over the next 24 hours. Severe stress and emotional trauma always precede the skin lesions.

Self-care:

1. Do not take NSAIDs, aspirin, or blood thinner medicine. These medicines can make purpura worse.
2. Protect your body from injury. Cuts or scrapes may cause bleeding that is difficult to control.
3. Do not play contact sports.
4. Control bleeding.

Low on Vitamin C This essential vitamin helps make collagen, an important protein that keeps your blood vessels healthy. If you don’t get enough vitamin C in your diet, you may notice that you bruise easily.

Symptoms of purpura

• Low platelet count, which may lead to increased bleeding after an injury, bleeding gums or nose, or blood in urine or bowel movements.
• Sore, swollen joints, particularly in the ankles and knees.
• Gut problems such as nausea, vomiting, diarrhea, or stomach pain.

People with sepsis often develop a hemorrhagic rash—a cluster of tiny blood spots that look like pinpricks in the skin. If untreated, these gradually get bigger and begin to look like fresh bruises. These bruises then join together to form larger areas of purple skin damage and discoloration.
