Does your child have these symptoms? Let's be aware of Reye's Syndrome!

Have you ever noticed that your little one has a fever or a cold, and then suddenly their behavior changes, vomiting frequently, or becoming very sleepy? If you see such changes, don't ignore them as normal. Because, it could be a symptom of a rare but potentially dangerous condition called "Reye's Syndrome." Let's talk about this today.

What is Reye's Syndrome?

Simply put, Reye's Syndrome is a rare but potentially serious condition. It occurs when a child's brain swells and liver function suddenly stops after a viral infection, usually a cold, flu, or chickenpox. This condition is often seen when children are given aspirin to control the symptoms of a viral infection. These symptoms can appear within a week of the start of the viral infection.

Who is most likely to develop Reye's Syndrome?

This is mainly considered a childhood disease. However, it can occur at any age. However, it is most commonly seen among children under the age of 18. This condition is reported especially during the autumn and winter seasons (in our country, during the rainy season, when viral diseases are prevalent).

How common is this situation?

In fact, Reye's Syndrome is now a very rare condition. For example, in the United States, only two cases of this disease are reported each year.

The main reason for this is that people are now more aware of this disease. In particular, many parents know that it is not a good idea to give aspirin to a child to treat the symptoms when they have a fever. Also, vaccinations against viral diseases such as influenza and chickenpox have reduced the prevalence of this disease.

How does Reye's Syndrome affect a child's body?

After a viral infection, such as a cold or chickenpox, your child may start to develop new symptoms within a few days (maybe a week). The most important thing to remember is to never give your child aspirin for their symptoms without medical advice. Doing so can increase the risk of Reye's Syndrome.

Reye's Syndrome causes a sudden increase in pressure inside a child's brain, which can lead to sudden changes in behavior and personality. Imagine your playful, happy child suddenly losing interest in their favorite toys, or becoming easily angry and agitated over seemingly insignificant things. These changes in mood can be the first signs of Reye's Syndrome. If you recognize these symptoms early, you can start treatment quickly and help your child recover.

What are the symptoms of Reye's Syndrome?

Symptoms can vary from person to person, and they also vary depending on the severity of the illness. The first symptoms are those of a common viral infection. That is, a cold, a sore throat, a fever, or chickenpox. After about five to seven days of symptoms of this viral infection, symptoms related to Reye's Syndrome begin to appear. They are:

• Frequent vomiting.
• Feeling extremely tired and sleepy .
• Things like anxiety, memory loss, confusion, and hallucinations .
• Behavioral changes: stubbornness, quick temper, quarrelsomeness.
• Rapid breathing.

These changes in brain function occur due to increased pressure inside the skull (`(Intracranial pressure)`). At the same time, liver function is also impaired. If the disease becomes more severe, you may also see symptoms such as:

• Seizures.
• Coma is a state of unconsciousness, similar to falling into a deep sleep.
• Complete loss of consciousness.
• Blood clotting problems.
• Increased ammonia levels in the blood.

Important: If your child shows one or more of these symptoms, whether during a viral fever or a few days after the fever has subsided, you should seek medical advice immediately, as these can be life-threatening.

What causes Reye's Syndrome?

In fact, the exact cause of Reye's Syndrome has not yet been discovered.

However, this condition is often caused by giving aspirin or salicylates to a child with a viral infection (such as the flu or chickenpox) to control symptoms. Some viral infections that can cause Reye's Syndrome include:

• Flu
• Chickenpox
• Respiratory infection
• Common cold

The symptoms of Reye's Syndrome are caused by fluid buildup or increased pressure in the brain tissue (cerebral edema) and changes in the liver.

Some studies suggest that this condition in the liver occurs due to damage to the mitochondria (`(Mitochondria)`) in the cells. Mitochondria (`(Mitochondria)`) are, simply put, the little power plants that provide energy to our cells. When these are damaged, liver function is impaired and symptoms appear. However, it is not yet clear why these mitochondria (`(Mitochondria)`) are damaged.

Does Aspirin Cause Reye's Syndrome?

Studies have shown that aspirin or a substance called salicylate can trigger Reye's Syndrome and increase the severity of symptoms. However, as mentioned earlier, the exact cause is still a mystery. Therefore, be sure to talk to a doctor before giving your child aspirin when he or she has a viral illness like the flu. Read the label of any medicine you give to a child carefully, making sure it is age-appropriate and how to give it. Ask your doctor if you have any questions.

How Reye's Syndrome Works in the Body (Pathophysiology)

The full details (`(Pathophysiology)`) of exactly how this disease works in a child's body are still not fully understood.

However, studies show that this condition develops when damaged mitochondria (`(Mitochondria)`) cells combine with a viral infection. If aspirin enters the child's body at this time, the damage to the mitochondria (`(Mitochondria)`) increases and the symptoms become worse. Due to the damaged mitochondria (`(Mitochondria)`), the ammonia level in the blood increases. Then the brain starts to swell (`(Cerebral edema and intracranial pressure)`). When the pressure on the brain increases too much, the fatty tissue in the kidneys starts to be damaged (`(Fatty degeneration)`), and the function of the nerve cells (`(Neurons)`) also decreases.

How is Reye's Syndrome diagnosed? (Diagnosis)

Doctors may suspect Reye's Syndrome if a child has a viral infection and then shows symptoms consistent with Reye's Syndrome, such as vomiting and behavioral changes (such as agitation, confusion). They will then perform various tests to rule out other conditions that can cause similar symptoms.

If your child is diagnosed with Reye's Syndrome, it will be classified into stages based on its severity. These stages are marked with Roman numerals from I (one - least severe) to V (five - most severe).

What tests are used to diagnose the disease?

The doctor may perform several tests to confirm the diagnosis. These include:

• Blood tests: Check the ammonia level in the blood and check for toxins in the urine.
• Imaging tests: An MRI or CT scan of the brain.
• Liver biopsy: Taking a small piece of the liver for examination.
• Spinal tap: Examination of the fluid surrounding the brain and spinal cord (cerebrospinal fluid).

Can Reye's Syndrome be misdiagnosed?

Because the symptoms of Reye's Syndrome are similar to those of many other conditions, it can sometimes be misdiagnosed. However, this is not uncommon. Some of the conditions that can be misdiagnosed include:

• Encephalitis (brain fever)
• Meningitis (`(Meningitis)`)
• Diabetes (`(Diabetes)`)
• Drug overdose
• Poisoning (`(Poisoning)`)
• Sudden infant death syndrome (`(Sudden infant death syndrome)`)
• Mental illness

How is Reye's Syndrome treated?

The main goal of treatment is to protect the child's brain. This means reducing brain swelling, repairing damage to the liver and metabolic processes (`(Metabolic injury)`), and preventing lung complications. Treatment can include the following:

• To make breathing easier, insert a tube into the windpipe (endotracheal intubation) or connect to a ventilator.
• Keeping the baby's head elevated.
• Giving medications to reduce ammonia levels in the blood (`(Ammonia detoxicants)`).
• Giving medication to control blood sugar (`(Glucose)`).
• Give vitamin K or plasma to improve blood clotting.

If your child is diagnosed with Reye's Syndrome, they will be admitted to the Intensive Care Unit (ICU) immediately and treatment will begin. The medical team will constantly monitor everything, including the child's body temperature and vital organ function, to see if the treatment is successful.

Are there any side effects of the treatment?

Most children diagnosed with Reye's Syndrome recover completely. However, if the child's brain swelling is very severe, some side effects may occur. These include:

• Memory loss (`(Memory loss)`)
• Learning difficulties (`(Difficulty learning)`)
• Loss of vision and hearing
• Trouble with speech and language
• Difficulty moving the body and performing daily tasks, such as getting dressed.

In cases like this, the child needs special support and care as he grows up.

How quickly will the child recover after treatment?

After treatment, once the swelling in your child's brain has subsided, he or she will begin to recover. It may take a few days to a few weeks for your child to recover enough to leave the hospital. The medical team will keep you updated on your child's progress.

What can I expect if my child has Reye's Syndrome?

The prognosis of a child's illness depends on the severity of the diagnosis, especially the extent of brain swelling and the level of ammonia in the blood. If the illness progresses rapidly and the child falls into a coma, the chances of recovery are slim. However, if the illness is diagnosed and treated early, the chances of recovery are very high.

The mortality rate for children diagnosed with Reye's Syndrome is approximately 21%. This ranges from less than 2% of children with stage I (mild) disease to 80% of children with stage V (coma). Early recognition and treatment significantly increase the chances of survival.

Children who experience severe symptoms of Reye's Syndrome may develop side effects that last into adulthood. For example, brain damage, cognitive development problems, epilepsy, muscle weakness, and neurological problems.

Is there a specific cure for Reye's Syndrome?

There is no specific cure for this. However, most children recover completely, depending on the diagnosis. Treatment aims to reduce symptoms and prevent long-term complications or death.

How to prevent Reye's Syndrome?

This is the most important thing we all need to know. Since there is a link between aspirin and Reye's Syndrome, this disease can be prevented by avoiding giving aspirin to children, especially children under 16 years of age. If your child needs aspirin to treat a medical condition, never give aspirin without talking to a doctor about it.

Always read the label carefully before giving a child any medicine, check the age-appropriateness of the medicine, and check the instructions for how to give it. If in doubt, ask your doctor or pharmacist.

When should I see a doctor?

If your child shows any symptoms of Reye's Syndrome after a viral fever or infection, or if you have given your child aspirin or a salicylate-containing medicine without medical advice, see a doctor immediately.

When should I go to the Emergency Department (ETU) ?

If your child has a seizure (`(Seizures)`), which means they temporarily lose consciousness, jerk their arms and legs uncontrollably, become agitated, or show signs of confusion, call 911 immediately, or take your child to the nearest emergency room. Seizures usually last from 30 seconds to about two minutes.

What questions should I ask my doctor?

• Can my child still have symptoms of Reye's Syndrome after leaving the hospital?
• How will a diagnosis of Reye's Syndrome affect my child's future?
• What medications should I not give my child when he is sick?

Can a single dose of Pepto-Bismol® cause Reye's Syndrome?

Pepto-Bismol® also contains a substance called salicylate, which is similar to aspirin. Therefore, it is not recommended to give it to children without medical advice. Giving aspirin during a viral infection such as the flu can cause symptoms of Reye's Syndrome. However, as mentioned earlier, the exact cause of Reye's Syndrome is not yet known. Always read the label or ask your pharmacist or doctor before giving any medicine to a child.

Finally, the most important message

If you are aware of the symptoms of Reye's Syndrome and notice a change in your child's behavior or new symptoms after a viral infection, it is best to see a doctor as soon as possible. Keep your child up to date with their vaccinations. This is especially important during times when viral infections are common (such as the rainy season). If your child is diagnosed with Reye's Syndrome, your medical team will keep you informed about your child's health status and provide you with the necessary support. The most important thing is to stay calm and act wisely.
