What are the chances of having a second child with cystic fibrosis?

1 in 4 or 25% Genetic counseling prior to pregnancy is very important if there is a family history of cystic fibrosis. There are many options available to parents who have already had a child with cystic fibrosis.
Possible every time. If you look at the genetics, the first affected baby tells you both parents carry a copy of the defective recessive gene. That means every time they get pregnant there is only 3 possible outcomes. Affected (CF),carrier, or non-carrier normal. The percentages are 25/50/25.You can look on the issue as having a 75% chance of healthy 2nd kid, or not.
1 in 4 or 25% For two parents who are carriers there is a 25% chance their child will have the disease, 50% the child will be a carrier of the disease and 25% chance that the child will neither be a carrier nor have the disease.

Can you tell me if a baby has a good chance of getting cystic fibrosis will the baby show symptoms right away?

Not necessarily. Depending on the expression of any CF genes it may present at birth with sticky poo & bowel obstruction or not be detected for months. Many states now include CF as part of their newborn screening programs to facilitate early recognition and treatment. Read more...
Variable. CF newborn screening programs can detect CF early on, so that treatment can be initiated earlier. If an infant begins to have symptoms consistent with cf, the test should be repeated even if the screening was negative at birth. Symptoms can begin at any time and this depends on a number of factors, including the specific genetic mutation of the CF gene. I hope this helps. Read more...

My baby was born 4 weeks early and had a meconium plug that didn't pass till hour 57. Cystic fibrosis has been ruled out. What are the chances it's hirschsprungs? Or could it just be chance?

Likely it's chance. CF is one of the causes of meconium plug, but mostly it's a random happenstance. Ruling out CF is important. As long as your child is starting to have normal stools now, and they are fairly regular, it's very unlikely it's hirschsprungs. Generally anal stenosis, hirschsprungs, or other forms of obstruction would cause chronic constipation. If your child is stooling normally, i'd go with it. Read more...

Mecon. plug syndrome. Meconium plug syndrome has been described in infants born premature or of diabetic mothers. Essentially there is immaturity of ganglion cells in large bowel. This is a transient problem that does usually not cause difficulties later on in life. Initially child needs stimulation to bowel, enema etc, to move the plug out of bowel.Radiographic enema sometimes shows characteristic pattern. Read more...

How can I cope with a child with cystic fibrosis?

Clinic/online. Your CF clinic should be able to help you and other family members, and direct you towards available help channels, a lot of them online. The clinic's social worker should be a great source for that information.

What are the annual hospitalization costs of having a child with cystic fibrosis?

Heavy. The new science of epigenetics tells us that our genes can be manipulated by diet and non-caloric supplements. It does not cure the disease but it sure helps! I have done it with some children wth cystic fibrosis. Recurrent lung infections are the major problem. Read more...
Varies considerably. There is considerable variance between children and between institutions for the cost of of hospitalizing a child with cf. Children have variable needs for hospitalization depending on their genotype and adherence to their regimen, and (unfortunately) there is a large amount of variance in practices while hospitalized and costs for these practices.

Does a child with cystic fibrosis have to live in a clean and dust free environment?

No. Clean helps & dust free helps for any kid.To some extent this ideal is relative and perfection on either point is unrealistic. With a stable hygienic environment, close monitoring by a CF center, & proper nutrition, these kids do well.Your CF center should have guidelines for healthy living they will share with you during your regular followups.

Is it important for a child with cystic fibrosis to be in a moderately clean and dust free environment?

Yes. Avoiding respiratory irritants is a good rule for a child with cf, but kids with this disease should not be restricted from living a life as normal as possible. Read more...
Yes. Moderately is the key word here. The germs that cause problems in children with CF often come from within them or from a hospital environment. Thus, while they should not be around other folks with cf, they don't need to be "kept in a bubble". Children with CF can also have asthma, so if allergies are a trigger, exposure to dust and other allergens can cause more symptoms. Playing outside is fine. Read more...
