Does your little one often get a runny nose? Can't see his body after eating? Does he make a whistling sound when breathing? These could be symptoms of a common cold, but sometimes there could be something more serious behind it. As a mother, it's only natural for you to be concerned about these things. Today, we're going to talk about a rare but important condition and the special test that can be used to diagnose it.
First, let's see, what is cystic fibrosis?
Simply put, Cystic Fibrosis (CF) is a genetic condition that is passed down through our genes, meaning it is inherited from birth. It is not a contagious disease. The mucus and other secretions produced by a person with this disease are much thicker and stickier than those produced by a normal person.
Think about it, the walls of the tubes (like pipes) in our bodies normally have a thin, slippery layer of mucus. This is what keeps our organs moist, clean, and safe. But in someone with CF, this mucus becomes thick, sticky, and gummy. This thick mucus begins to block the tubes and passages, especially in the lungs and digestive system (especially the pancreas).
This can lead to breathing difficulties, frequent lung infections, and other nutritional deficiencies because the body doesn't absorb the food it eats properly. In addition to the lungs and pancreas, the condition can also affect the liver, sinuses, intestines, and reproductive organs.
CF is a chronic disease. This means that it cannot be completely cured, but with proper treatment and management, symptoms can be controlled and people can live a normal life. It is also a progressive condition in which symptoms gradually worsen over time.
What are the symptoms of a young child with CF?
A child with CF may show one or more of these symptoms at the same time. Be aware of these symptoms in your child. But remember, not every child with these symptoms has CF. But it is important to be aware of them.
| Symptom | A Simple Explanation |
|---|---|
| Failure to thrive | Even though the baby drinks a lot of milk and eats well, he is thin and does not gain weight that is appropriate for his age. The reason for this is that the pancreatic ducts are blocked by mucus, preventing the enzymes needed to digest food from reaching the intestines. |
| Loose or oily stools | Stool may become pale in color, have a foul odor, and appear oily. This is because fat from food is excreted undigested. |
| Difficulty breathing and frequent wheezing | Thick mucus gets stuck in the lungs, making it difficult to breathe. When you breathe, especially when you exhale, you hear a whistling sound coming from your chest. |
| Frequent lung infections | Because bacteria grow easily on thick mucus, diseases like pneumonia or bronchitis often develop. |
| Cough that won't go away | There may be a persistent, phlegmy cough as the body tries to clear the mucus that is stuck in the lungs. |
| Feeling a salty taste on the child's skin | This is a very special feature. Parents say that when they kiss their child, they feel a salty taste on their skin. We will talk about the reason for this next. |
How do doctors diagnose this disease? - Sweat Test
When a child has the above symptoms, a doctor may suspect this and recommend several tests. These include genetic tests and chest X-rays. However, the most important test to confirm the diagnosis of CF is the sweat test.
This is a very simple thing to do. Simply put, our sweat contains salt. This salt is made up of two components called chloride and sodium. Because this chloride doesn't move in and out of the cells of a person with CF, their sweat contains much more chloride than a normal person. What a sweat test does is measure the amount of chloride.
How is a sweat test performed? Will it hurt the baby?
As a mother, it's normal for you to have this question. But there's no reason to be afraid. This is not a painful test at all.
This test can be done on anyone of any age. However, newborn babies may not be able to produce enough sweat for the test in the first few days of life. Therefore, this test is usually done when the baby is two to four weeks old.
Here's how the test is done:
1. First, a member of the medical staff will thoroughly clean a small area on the baby's arm or leg (usually the forehead).
2. Then, a gel containing a chemical called pilocarpine is applied to the area, and a small electrode is placed on top of it.
3. Now a very small, barely noticeable electrical stimulation is given through this electrode. Don't worry, this doesn't use needles, and it won't hurt the baby in any way. You may feel a slight tickling sensation. This stimulates the sweat glands and speeds up the production of sweat.
4. After a few minutes, the area is cleaned and a special device (like a plastic coil) that collects sweat is placed on it and tied.
5. When the baby plays for about 30 minutes, the required amount of sweat is added to this.
6. The collected sweat sample is then sent to the lab to measure the amount of chloride.
What does the test report say?
Once the test report is received, the doctor can determine whether the child has CF or not based on the values. The values are measured in units called `mmol/L` (millimoles per liter).
Remember, only your doctor can interpret these results and advise you on what to do next. So don't panic and make decisions based on the numbers on the report.
| Chloride Level | What does that mean? (What it means) |
|---|---|
| If more than 60 mmol/L | It is likely that the child has CF. The doctor may order further tests to confirm this. |
| If less than 40 mmol/L | The child does not have CF. The doctor will look for other causes for the symptoms. |
| Between 40 and 60 mmol/L | This is an intermediate result. You may need to repeat the test. Your doctor may also recommend further testing to look for atypical forms of CF. |
How to prepare the baby for the test?
This is the easiest part. This test does not require any special preparation.
- There is no need to change your baby's diet, medication, or activities before the test. You can continue your day as usual.
- The most important thing is to not apply any creams or lotions to your baby's body the day before the test. Especially not on the arm or leg being tested. These can affect the test results.
If your child has these symptoms, don't panic or panic, but see a qualified doctor as soon as possible for advice. The sooner the disease is diagnosed, the better the chances are of starting treatment and giving the child a healthy life.
Take-Home Message
- Cystic fibrosis is a genetic disease that is inherited from birth and causes thickening of the body's mucus membranes, affecting organs such as the lungs and pancreas.
- It is very important to see a doctor if your child has symptoms such as not gaining weight, frequent chest congestion, difficulty breathing, and oily stools.
- Sweat testing is the most important, painless, and safe test to diagnose this disease.
- This test measures the amount of chloride (salt) in sweat. Children with CF have much higher than normal levels of chloride in their sweat.
- Don't panic about the test results, always talk to your doctor to get a clear understanding.
