Is your little one suddenly developing purple spots on their body? It could be Henoch-Schönlein Purpura (HSP)! Shall we talk about this?

It's normal to be a little worried if your child suddenly notices small purple spots on their body, especially on their legs and buttocks, after playing happily. Sometimes these spots can be accompanied by stomach aches and joint pain. When we see something like this, we think of one thing after another. So today we're going to talk about a condition that can cause these symptoms, but most of the time it's nothing to worry about, but it's very important to be aware of. That's Henoch-Schonlein Purpura, or HSP for short.

What is Henoch-Schönlein Purpura (HSP)?

Simply put, Henoch-Schonlein Purpura (HSP) is a condition in which the tiny blood vessels in our bodies become swollen or inflamed. Doctors call this `` vasculitis .'' Think of it like the tiny blood vessels throughout our bodies getting irritated and swollen. This swelling is what causes all these problems.

When blood vessels become swollen in this way, small blood cells begin to leak out. Just like a water pipe leaks water. These blood cells can leak into the skin, mucous membranes (such as the moist membranes inside our mouths and noses), or into internal organs. When they leak into the skin, they cause those purple, bruise-like spots. We call those spots `(purpura)`.

Most often, this HSP condition affects the blood vessels in the skin, joints, intestines (bowels), and kidneys. But the good news is that most children who develop HSP recover completely within a few weeks without any long-term problems . So it's important to know the truth before you panic.

What are the causes of HSP?

Doctors still can't say for sure what causes HSP. But they think it most likely starts after an infection . It could be a bacterial, viral, or parasitic infection. For example, some children may develop the condition after a sore throat.

Apart from that, it is suspected that it can be caused by certain medications and food allergies . Some people may also have a genetic predisposition. Researchers are still searching for the exact cause of HSP.

HSP occurs when our immune system does not work properly. We have a special type of protein called `(Immunoglobulin A - IgA)` in our body. Its main function is to fight infections and protect us from diseases. But what happens in the body of a person with HSP is that this `(IgA)` protein gets deposited in those small blood vessels. That is when that `(vasculitis)` condition occurs, which causes the blood vessels to swell.

HSP is the most common type of vasculitis in children . Although it can occur at any age, it is most common in children between the ages of 2 and 6. It is about twice as common in boys as in girls. It also tends to occur more frequently in the fall and winter (i.e., toward the end of the year).

What are the symptoms of HSP?

Now let's see what symptoms a child may exhibit if they have HSP.

Skin spots `(Purpura)`

This is the main and most obvious sign of HSP . Small, purple-colored spots that look like bruises appear on the skin. These spots do not turn pale when you look at them (a non-blanching rash).

• These spots are most often seen on the lower legs and buttocks .
• Sometimes these spots can also be seen on the hands, face, and central parts of the body, such as the chest and stomach.
• These spots may appear suddenly, or they may increase gradually.

Joint pain and swelling

For many children, joint pain and swelling may occur about a week or two before the skin rash appears.

• It most often affects the joints of the knees and ankles .
• Sometimes joints such as the elbow and wrist can also be affected.
• This pain may make it difficult for the child to walk.

Stomach ache

Stomach upset often occurs after skin rashes appear.

• You may experience abdominal cramps.
• Nausea and vomiting .
• Some children may also have blood in their stools (blood in BMs/stool). This is a sign to be concerned about.

Effects on the kidneys

In some cases, HSP can also affect the kidneys .

• A small amount of blood or protein may be passed with the urine .
• Sometimes the urine may appear red in color (hematuria).
• Although this is not serious in most cases, it is very important to see a doctor to check if there is any effect on the kidneys.

Symptoms of HSP usually last about a month , after which most children recover on their own.

How do doctors accurately diagnose HSP?

When you take your child to a doctor, the first thing they do is examine the child thoroughly. Since those purpura spots are present in almost all HSP patients, they are a great help for the doctors in diagnosing the disease.

In addition, the doctor may also perform tests such as:

• Blood tests: These can be used to check kidney function, check for infections, and check for blood clotting problems.
• Urine test: Check for blood or protein in the urine. This can give an idea of ​​whether the kidneys have been affected.
• Stool test: Check for blood in the stool.
• Ultrasound scan: If your child has severe abdominal pain, this can help to rule out other problems inside the abdomen, especially a condition called intussusception.

After conducting all these tests, the doctor determines whether you have HSP and its severity.

What are the treatments for HSP?

Most of the time, HSP resolves on its own without any specific treatment . That's the good news. However, if HSP has affected your kidneys, then medical treatment may be necessary.

To help your child feel comfortable and control symptoms, your doctor may recommend medications such as:

• Antibiotics: These are only given if it is thought that the HSP is caused by a bacterial infection.
• Pain relievers: For example, acetaminophen (like paracetamol) can help reduce joint pain and body aches.
• Anti-inflammatory medicines: For example, medicines like ibuprofen can help reduce pain and swelling in the joints.
• Corticosteroids: For example, medications like prednisone. These are only given if the child has severe stomach pain or has kidney disease. These should only be used under the supervision of a doctor.

Things you can do at home

In addition to medication, there are things you can do at home to keep your baby comfortable:

• Let your child rest well: Reduce the amount of running and playing around, and encourage them to stay in bed and read a book.
• Give plenty of fluids to drink:Giving things like water and fruit juice can help prevent dehydration.
• If your joints are swollen and painful: You can keep them elevated for a while, and maybe even put an ice pack on them if your doctor tells you to.

The most important thing is to take your child to a doctor immediately if they refuse to eat or drink, if they have severe stomach pain, or if they show signs of kidney problems (e.g., decreased urination, swelling). They may need to be hospitalized for treatment.

Are there other complications that can occur due to HSP?

About half of children with HSP may have some effect on their kidneys. In most cases, this is only a minor effect and resolves without any special treatment. However, very rarely, some children may develop serious conditions such as kidney failure. Such children may need to see a kidney specialist (nephrologist) for further testing.

Another rare but very serious medical condition is intussusception. This is when one part of the intestine telescopes into another part . This can cut off the blood supply to that part and cause a blockage. This is an emergency that needs to be treated immediately. If your child suddenly has severe, intermittent abdominal pain, is vomiting, or has jelly-like blood in their stool, you should suspect this.

Other important things we need to know

• The best thing is, most children who develop HSP recover completely within a month and do not develop any long-term problems.
• Some children may develop HSP again. This usually happens a few months after the first episode. However, if it does occur again, it is often less severe than the first episode .

So, what is the take-home message from all of this?

Okay, so, from what we've talked about, these are the most important things to keep in mind:

• HSP is a condition that can affect young children, causing swollen blood vessels. The main symptom is purple spots.
• Most of the time, this will heal on its own.
• Joint pain, stomach upset, and kidney damage can occur.
• If you see strange spots on your child's body, if they complain of stomach pain, or if their joints hurt, definitely take them to a doctor. Don't panic, but seek medical advice immediately.
• Follow the doctor's instructions carefully. Give your child plenty of rest and plenty of fluids.
• Most children recover completely. Be aware of rare complications.

Remember, you are not alone. Doctors are there to help you and your baby. Knowing this kind of information will give you great strength to take action in a timely manner.

So, I hope this information is helpful to you. Wishing your child a speedy recovery!
