Animals that receive a severe and blunt blow to the front of the abdomen can suffer from liver disease. Congenital adrenal hyperplasia (CAH) is a group of inherited genetic conditions that limit your adrenal glands' ability to make certain vital hormones.

Congenital adrenal hyperplasia - Symptoms and causes. Overview. Congenital adrenal hyperplasia (CAH) is a group of inherited genetic disorders that affect the adrenal glands, a pair of walnut- sized organs above your kidneys. A person with CAH lacks one of the enzymes the adrenal glands use to produce hormones that help regulate metabolism, the immune system, blood pressure and other essential functions. CAH affects the production of one or more of three steroid hormones: cortisol, whichregulates your body's response to illness or stress; mineralocorticoids, such as aldosterone, which regulate sodium and potassium levels; or androgens, such as testosterone, which are sex hormones.

Congenital Adrenal Hyperplasia In Adults

In many cases, CAH results in lack of cortisol and overproduction of androgen. The milder and more common form of CAH is called nonclassic. The classic form, which is more severe, can be detected in newborn screening programs.

Some forms of CAH can cause problems with normal growth and development in children and even be life- threatening. Although there is no cure, with proper treatment, most people with congenital adrenal hyperplasia can lead normal lives.

Symptoms. Signs and symptoms of congenital adrenal hyperplasia vary, depending on which gene is defective and the level of enzyme deficiency. There are two major types of congenital adrenal hyperplasia: Classic CAH. This more- severe form of the disease is usually detected in infancy. Nonclassic CAH. This milder and more common form may not become evident until childhood or early adulthood. Classic CAHApproximately two- thirds of people with classic CAH are classified as having the salt- losing form, while one- third have the simple- virilizing form. In both forms, affected females have genital ambiguity.

A child with classic CAH may experience: A lack in the production of cortisol in both the salt- losing and simple- virilizing forms. Most of the problems caused by classic CAH are related to a lack of cortisol, which plays an important role in regulating your blood pressure, maintaining blood sugar and energy levels, and protecting your body against stress. A lack in the production of aldosterone in the salt- losing form.

This can lead to low blood pressure, a lower sodium level and a higher potassium level. Sodium and potassium normally work together to help maintain the right balance of fluids in your body. Excess production of the male sex hormones (androgens such as testosterone).

This can result in short height, early puberty and in females, abnormal genital development while in the womb. Signs and symptoms of classic CAH in infants include: In females, enlarged clitoris or genitals that look more male than female (ambiguous genitalia) at birth, but males have normal appearing genitals. Significant illness related to a lack of cortisol, aldosterone or both (adrenal crisis), which can be life- threatening. Signs and symptoms of classic CAH in children and adults include: Very early appearance of pubic hair. Rapid growth during childhood, but shorter than average final height.

Nonclassic CAHThis form of CAH is milder than classic CAH. Often there are no symptoms at birth. The condition is not identified on routine infant blood screening and often only becomes evident in late childhood or early adulthood. Hormone deficiency may only involve cortisol levels. Although teenage and adult females may have normal appearing genitals at birth, later signs and symptoms often include: Irregular or absent menstrual periods.

Masculine characteristics such as facial hair, excessive body hair and a deepening voice. Severe acne. In both females and males, signs and symptoms of nonclassic CAH also may include: Early appearance of pubic hair.

Rapid growth during childhood, but shorter than average final height. When to see a doctor. Classic CAH is usually detected at birth through required newborn screening or when female babies show ambiguous genitalia. CAH may also be identified when male or female babies show signs of severe illness due to low levels of cortisol, aldosterone or both. In nonclassic CAH, you may notice signs and symptoms of early puberty in your toddler or child. In this case, or if you have concerns about your child's growth or development, make an appointment with your child's pediatrician.

If you're pregnant and may be at risk of CAH because of your own medical history or your ethnicity, ask your doctor about genetic counseling. Causes. In 9. 5 percent of cases, the enzyme lacking in congenital adrenal hyperplasia is 2. CAH may sometimes be called 2. There are other much rarer enzyme deficiencies that also cause CAH. CAH is passed along in an inheritance pattern called autosomal recessive.

Children who have the condition have two parents who either have CAH themselves or who are both carriers of the genetic mutation that causes the condition.

Congenital adrenal hyperplasia You and Your Hormones from the Society for Endocrinology. What is congenital adrenal hyperplasia? Congenital adrenal hyperplasia is an inherited condition caused by mutations in genes that code for enzymes involved in making steroid hormones in the adrenal glands. The most common enzyme defect, 2. What causes congenital adrenal hyperplasia? Congenital adrenal hyperplasia results from mutations in the gene that codes for one of several enzymes responsible for making steroid hormones in the adrenal glands. The most common enzyme to be affected is 2.

In about two- thirds of affected individuals, the enzyme defect in the adrenal may also affect the production of the hormone aldosterone, which is responsible for retaining salt in the body. Single mutations in the gene that codes for 2. However, congenital adrenal hyperplasia is a recessive disorder meaning you must inherit a mutation in the gene from both parents in order to develop the condition. Thus, approximately 1 in 1.

In patients with congenital adrenal hyperplasia, the body recognises the lack of cortisol and therefore tries to stimulate the adrenal glands to try to produce sufficient levels. However, because there is an enzyme defect, the adrenal glands cannot produce cortisol and instead produces excess amounts of precursor steroids. These precursor steroids are mostly androgenic, that is, similar to the male hormone, testosterone.

An excess of male hormones leads to development of male characteristics and precocious (early) puberty. What are the signs and symptoms of congenital adrenal hyperplasia? Moral Stories For Adults In Tamil. A foetus affected by congenital adrenal hyperplasia will produce excessive male hormones during development. If the foetus is female, this will result in virilisation of the external genitalia (i. As both boys and girls with congenital adrenal hyperplasia have a deficiency of cortisol, they are likely to present in the first few days or weeks of life with an adrenal crisis unless treated with steroid replacement. During childhood, the normal healthy child switches off their production of sex steroid hormones.

However, if the infant has untreated congenital adrenal hyperplasia, they will produce excessive levels of male hormones such as testosterone from their adrenal glands. This will result in rapid growth of both boys and girls, with the additional effect of virilisation (development of male characteristics) of girls. The adrenal androgens also create an early or precocious puberty with pubic hair growth, body odour, and enlargement of the penis or clitoris at a younger age than would normally be expected. This can cause early fusion of the bones. Thus, both boys and girls with poorly controlled congenital adrenal hyperplasia will have rapid growth in early childhood and will be a tall child but a short adult. In adult life, if the male hormones are not controlled, then a woman will be virilised and in both men and women there might be multiple health problems, including infertility and the risk of developing obesity and hypertension due to exposure to excess steroids. Some individuals with mild forms of congenital adrenal hyperplasia can be diagnosed later in childhood or in adult life.

How common is congenital adrenal hyperplasia? Congenital adrenal hyperplasia affects 1 in 1. European populations; however, it does vary between different populations and is more common in some. Is congenital adrenal hyperplasia inherited? Congenital adrenal hyperplasia is an inherited condition through mutations in the genes that code for adrenal enzymes. It is a recessive disorder, which means that you need to inherit a mutation from both parents. Most parents who have a single gene mutation will not be affected by the condition; it is only when you inherit a mutation from both your mother and father that you develop the condition. There are a variety of mutations, some of which severely affect enzyme activity and others that have only a minor effect.

Thus, there is a variety of severities for the condition. Monster Costumes For Adults Uk more. How is congenital adrenal hyperplasia diagnosed? Congenital adrenal hyperplasia is usually diagnosed around the time of birth either by a screening test in the newborn, which is done in some countries but not in the UK, or through the clinical presentation. In a female infant born with ambiguous genitalia, congenital adrenal hyperplasia is often suspected. If the baby suffers from an adrenal crisis in the first few weeks of life then this will also precipitate the diagnosis.

Children with milder forms (particularly boys) are often diagnosed between two to four years of life with signs of early puberty. How is congenital adrenal hyperplasia treated? The goals of treatment for congenital adrenal hyperplasia are to both replace the deficient steroid hormone cortisol and to normalise the excessive male hormone secretion. This is done by giving steroid hormone therapy, usually in the form of hydrocortisone during childhood, and a variety of steroids in adult life.

Congenital adrenal hyperplasia Great Ormond Street Hospital. Lacking this hormone means that the body is less able to cope with stress, either emotionally or physically, which can be life threatening. It also makes the level of androgen (male hormone) increase, which causes male characteristics to appear early in boys or inappropriately in girls. The adrenal glands rest on the tops of the kidneys.

They are part of the endocrine system, which organises the release of hormones within the body. Hormones are chemical messengers that switch processes within the body on and off. The adrenal glands consist of two parts: The medulla (inner section) which makes the hormone ‘adrenaline’ which is part of the ‘fight or flight’ response a person has when stressed. This is not usually affected in CAH. The cortex (outer section) which releases several hormones.

The most important ones are: Aldosterone – this helps regulate the blood pressure by controlling how much salt is retained in the body. Cortisol – this is the body’s natural steroid and has three main functions: helping to control the blood sugar levelhelping the body deal with stresshelping to control blood pressure and blood circulation. Androgen – male hormone produced by both males and females. What causes CAH? CAH is an inherited disorder – that is, it is passed on from parent to child. Most types of CAH are autosomal recessive disorders. This means that both parents are carriers of the disease. Human beings have about 3.

The genes are arranged in pairs (one of the pair from each parent) on 2. Inevitably, some of these genes are faulty.

A normal gene can overcome a faulty one, but if both genes in the pair are faulty, the genetic instructions cannot work. Most people carry different faulty genes but in CAH (and other recessive conditions) parents, though healthy themselves, carry the same faulty genes, and risk passing them on to their children.

Each pregnancy carries: a 2. In a small proportion of people, CAH is caused by a gene mutation (change) that happens by chance and cannot be predicted. A number of genes have been identified as causing different types of CAH – for instance, the most common form of CAH is called 2. CYP2. 1 being absent or changed. This means that aldosterone and cortisol are not produced but production of androgen is unaffected.

The gene affected results in different types of CAH, affecting people to varying degrees from mild to severe. CAH affects boys and girls in equal numbers, affecting between one in 1. What are the signs and symptoms of CAH? The symptoms that present and the age at which they become apparent depends on the degree of cortisol and/or aldosterone deficiency. Boys with severe CAH show symptoms soon after birth, when a baby develops heart rhythm abnormalities, dehydration and vomiting.

The levels of minerals (electrolytes) in the body are also affected, particularly showing low salt levels (hyponatraemia) and low blood sugar levels (hypoglycaemia). Females with severe CAH are born with virilised (male looking) genitalia, so confusion as to the gender of the baby may occur.

This is referred to as ambiguous genitalia. They too have low levels of minerals, especially salt, so show similar symptoms to boys. Children with mild CAH may not have the same mineral imbalances as more severely affected children. Later, other symptoms caused by the increase in androgen develop.

Girls will have abnormal or absent periods, a deep voice, early puberty and facial hair. Boys will have an enlarged penis, small testicles, early puberty and a deep voice. Both girls and boys may appear tall for their age but usually end up being short as adults. How is CAH diagnosed?

Most cases of CAH are diagnosed soon after birth or in early childhood, but less severe CAH may not become apparent until a child does not start puberty at the expected age. CAH can be diagnosed before birth now that the affected gene has been identified.

If the baby is an affected female, steroid treatment during pregnancy can reduce the effect of too much androgen in the body. If a baby is born with ambiguous genitalia, blood tests are usually used to determine genetic gender. Blood and urine tests are also used to work out the levels of minerals and hormones in the body, so that they can be replaced. X- rays to look at a child’s bone age may also be suggested.

Genetic testing may be used to identify the specific type of CAH and the associated gene deficiency or mutation. How is CAH treated? Children with CAH are usually cared for by a multidisciplinary team including endocrinologists (hormone specialists) and urologists (genitourinary system specialists). Initially, children with CAH will need to be stabilised with intravenous fluids to restore their electrolyte levels.

Once stable, cortisol and/or aldosterone replacement therapy can start with repeated blood tests to monitor hormone levels so the most effective dose can be prescribed.
