Sometimes when you look at a newborn baby, or a little older child, you may have noticed some changes. Perhaps a doctor has told you that your child has a condition called `(Congenital Adrenal Hyperplasia)` or `(CAH)`. Don't be scared when you hear this name. Although it is a little complicated, let's talk about it in simple, understandable Sinhala. Just like you would talk to your friend.
What is congenital adrenal hyperplasia (CAH)?
Simply put, CAH is a congenital, or genetic, condition that primarily affects the adrenal glands in our bodies. Remember, there are two small glands on top of our kidneys? That's what we call the adrenal glands . Although they are small, they produce several important hormones that are essential for the healthy functioning of our bodies.
Let's see what these hormones are:
- Cortisol: This hormone helps our body cope with stress, illness, and injury. It is also essential for regulating things like blood pressure, energy levels, and blood sugar levels.
- Aldosterone: This hormone helps maintain the right amount of salt (sodium) and water in our bodies. It is also needed to control blood pressure and blood volume.
- Androgens: These are the male sex hormones (for example, testosterone). These hormones are important for puberty, normal growth, and development.
Now, what happens to someone with `(CAH)` is that one or more of these enzymes that help the adrenal glands make those important hormones are reduced or missing. Without this enzyme, the adrenal glands cannot function properly. Then:
- Maybe you're not producing enough cortisol .
- It is possible that not enough aldosterone is produced.
- Perhaps too much androgen is produced.
This hormonal imbalance is what mainly happens in the condition `(CAH)`.
What are the main types of `(CAH)`?
There are two main types of CAH. These two types account for 95% of cases.
1. Classic CAH: This is the most severe and serious form of CAH. It can cause severe complications involving the adrenal glands, such as shock and even coma. It can be life-threatening if not diagnosed and treated early. This classic CAH condition is usually diagnosed at birth.
This also has two subtypes:
- Salt-wasting CAH: This is the most severe form of CAH. In this condition, the adrenal glands produce very little aldosterone. Without aldosterone, the body cannot control the amount of salt (sodium) in the blood. This causes excess sodium to be lost in the urine. In addition, there is low cortisol production, but high androgen production.
- Simple-virilizing CAH: This is a milder form of CAH . In this case, the aldosterone deficiency is not as severe. Therefore, there are no life-threatening symptoms. However, there is less cortisol production and more androgen production. This excess androgen production can cause symptoms related to sexual development.
2. Nonclassic CAH: This is the mildest form of CAH. It usually appears in late childhood, adolescence, or adulthood. Symptoms may or may not be present. This can also be caused by excess androgen production, which can lead to symptoms related to sexual development.
In addition to these main types, there are several other rare types of CAH, each with different symptoms.
Who can get CAH? How common is it?
This condition called ``(CAH)`` can develop in anyone. That means it can affect babies, children, adults, anyone.
In countries like America and Europe, classic CAH affects about one in ten thousand to fifteen thousand people. Nonclassic CAH is a little less common, affecting about one in one hundred to two hundred people. Both types are found all over the world.
What are the symptoms of `(CAH)`?
The symptoms of CAH can vary depending on the type and gender. For example, some babies are born with symptoms, while others develop symptoms as they get older.
Symptoms of Classic CAH
In classic CAH, androgen levels are very high. This can cause symptoms related to sex hormones. Both salt-wasting and simple-virilizing CAH can cause symptoms such as:
- Ambiguous genitalia in female babies: This means that the baby's external genitalia may look like a male baby's. However, the internal female genitalia (such as ovaries and uterus) are normal.
- Enlarged penis in male babies.
- Signs of precocious puberty: For example, a change in voice, severe acne, and early hair growth in the armpits, private areas, and face.
- The emergence of masculine characteristics in girls: muscle development, deepening of the voice, and the growth of unwanted facial hair.
- Very rapid growth (in the early stages).
- Irregular menstrual cycle.
- Benign testicular tumors.
- Infertility.
In addition, especially in people with salt-wasting CAH , hormonal imbalances can cause severe adrenal symptoms. These are very dangerous and require immediate treatment :
- Dehydration.
- Decreased sodium levels in the blood (Hyponatremia).
- Low blood pressure (Hypotension).
- Irregular heartbeat (Arrhythmia).
- Low blood sugar levels (Hypoglycemia).
- Increased acidity in the blood (Metabolic acidosis).
- Vomiting.
- Diarrhea.
- Weight loss.
- Shock state `(Shock)`.
Important: These symptoms of salt-wasting CAH, especially in a newborn, are an emergency. You should see a doctor right away.
Symptoms of Nonclassic CAH
Nonclassic CAH is a milder condition. You may not even know you have it. Symptoms are usually milder, but may include:
- Very rapid growth (in the early stages).
- Acne.
- Precocious puberty.
- Unwanted hair growth on the face or body of women.
- Irregular menstrual cycle.
- Infertility.
- Male pattern baldness (early).
- Males have large penises but small testicles.
What causes `(CAH)`?
In most cases, the main cause of CAH is a deficiency or absence of the enzyme 21-hydroxylase. Genetic mutations affect the levels of this enzyme. Rarely, a deficiency of the enzyme 11-hydroxylase can also cause CAH.
CAH is an autosomal recessive disorder . Do you know what that means? We get two copies of each gene - one from our mother and one from our father. CAH only occurs when a child inherits a copy of the gene that causes this enzyme deficiency from both parents. If a person has only one mutated gene, they can be a carrier of the disease but not show symptoms.
How do doctors diagnose (diagnose) the condition `(CAH)`?
Classic CAH
Before your baby goes home from the hospital, doctors will test them for CAH. This is part of the routine newborn screening . It is done by taking a small drop of blood from your baby's heel. This can tell if you have classic CAH.
If you are pregnant and you already have a child with CAH, you can have prenatal genetic testing during pregnancy . Your doctor can do an amniocentesis (a test of the fluid in your womb) or a chorionic villus sampling (a test of a piece of the placenta) to see if you have CAH.
Nonclassic CAH
Nonclassic CAH is usually diagnosed after you or your child starts showing symptoms. Sometimes, it can also happen in adulthood. Your doctor will do the following to diagnose the condition:
- A physical examination.
- Blood tests.
- Urine test.
- Genetic testing.
How is CAH treated?
Treatment for CAH depends on the type and severity of the symptoms. There is no cure for CAH. However, medications and other treatments can help control symptoms and lead a healthy life.
Classic CAH treatment
Your doctor will monitor your condition regularly. They will do regular blood tests to check your hormone levels. The main goal of treatment is to ensure normal growth and sexual development.
Your doctor may prescribe medications such as these to treat your symptoms:
- Salt supplements: Newborn babies may need sodium chloride supplements (especially salt-wasting formulas).
- Glucocorticoids: These work by replacing the hormone cortisol, which the body does not produce. You may need to increase the dose of this medication when you are sick, sad, or stressed.
- Mineralocorticoids: These are used to replace the hormone aldosterone, which is not produced by the body.
If you have Classic CAH, you must take these medications daily for the rest of your life. If you stop taking the medication, your symptoms will return.
Another treatment option is surgery for female babies with ambiguous genitalia. This surgery can be performed between two and six months after birth to restore the appearance and function of the external genitalia. In some cases, surgery can be delayed for several years. This should be discussed carefully with your doctor before making a decision.
Nonclassic CAH treatment
If you have no symptoms, you may not need treatment. If you have mild symptoms, you may be given low doses of glucocorticoids. These people usually do not need lifelong treatment.
If you or your child has CAH, it is important to seek mental health care. This is because the many issues and problems that come with the condition (such as physical changes, infertility, etc.) can have a psychological impact. Therefore, mental health support is an important part of CAH treatment. It can improve the quality of life.
What are the possible complications of CAH?
In classic CAH, especially the salt-wasting type, excess water and salt are lost in the urine. This can lead to serious complications such as electrolyte (e.g. potassium) imbalances . If left untreated, these imbalances can cause:
- Irregular heartbeat (Arrhythmia).
- Cardiac arrest.
- Even death can occur.
Untreated nonclassic CAH can also cause complications. For men:
- Early puberty.
- Shortness of stature (decreased height).
For women:
- Permanent male body features.
- Irregular menstruation.
- Infertility.
There is also a risk of some complications (such as infection, bleeding, and scarring) from surgeries performed on ambiguous genitalia.
Can `(CAH)` be prevented?
Because CAH is a genetic condition, it cannot be prevented. If someone in your family has CAH, or if you already have a child with CAH, consider genetic counseling and/or genetic testing . This will help you understand the risk of your children inheriting the condition.
How is the situation after treatment for `(CAH)`?
If diagnosed early and treated properly, people with CAH can live healthy, productive lives. People with Classic CAH will need to take medication daily for the rest of their lives. Symptoms may return if medication is stopped.
Most people with CAH are in good health, but they may be shorter than other adults. In some cases, CAH can affect fertility. If you were born with ambiguous genitalia, you may need psychological support. If you have any problems after treatment, don't be afraid to talk to your doctor.
How to lose weight with `(CAH)`?
Some medications used to treat CAH (especially glucocorticoids) can cause weight gain. Talk to your doctor about your weight. He or she can determine if the weight gain is due to the medication or another medical condition. Your medication dosage may need to be adjusted. He or she can also help you develop a diet and exercise plan to help you maintain a healthy weight.
Is `(CAH)` a disability?
Some organizations may consider adrenal gland diseases as a disability. Whether CAH qualifies as a disability is determined by the complications that arise from that specific disease.
Finally, things to remember (Take-Home Message)
It's normal to feel overwhelmed when you learn that your child has a genetic condition. However, children born with Congenital Adrenal Hyperplasia (CAH) have a better future if the condition is diagnosed early and treated properly.
Remember these things:
- (CAH) is a genetic condition that affects the production of hormones in the adrenal glands.
- Classic CAH is the most severe type and can be detected through newborn screening.
- Early diagnosis and lifelong medication (for classic CAH) are very important.
- Treatment can control symptoms and allow for normal growth and development.
- Some people may need mental health support and counseling.
- If you are planning to get pregnant and have a family history of CAH, talk to your doctor about genetic counseling.
Don't worry, you're not alone. If you have any more questions about `(CAH)`, ask your doctor. They can help you.
