FD 101: What is FD?

 

It's not pediatric cancer. It's not juvenile diabetes. But like these diseases, it kills children.

Familial Dysautonomia (pronounced "dys-auto-NO-mia" and referred to as FD) is a hereditary disorder that affects the nervous system. A typical cold for you or me can be life threatening to a victim of FD.

Children and adults with FD experience decreased or poor pain perception, which means they could break an arm and not even know it. They may also suffer from erratic or unstable blood pressure that causes them to feel dizzy and sometimes faint. They often have trouble swallowing so they are fed through tubes directly into their stomachs. Most suffer from scoliosis and some are blind. Any number of problems can arise from this debilitating disease.

FD is a way of life. Different from yours or mine, or any other "normal" person around us. FD is born the moment the child is born, and from that moment it affects every aspect of his or her life.

FD is not a malady, a virus or a bacteria. It is not contagious and cannot be acquired after birth.

Many children are born with gene disorders and struggle all their lives to learn how to overcome their disability. Most of them succeed. But those with FD have tougher battles because it affects every organ in the body.

An estimated 600 children have been diagnosed with FD since this disorder was recognized in 1949. Twenty years ago many FD victims died before reaching the age of 10. Statistics are improving, however. Due to the better understanding of the disorder, half may reach the age of 25. Still not a long life in terms of the average person.

It is estimated that one in 27 Jews of Eastern European (Ashkenazi) origin are carriers of the FD gene. But without proper screening, more FD cases are bound to appear.

Only two doctors in the world treat FD: one in New York and one in Israel, Jerusalem. Since it is such a rare disease, hospitals are not experts at either recognizing or treating FD. Much effort has gone into spreading the knowledge FD and its treatment to as many doctors as possible. Spearheading this activity are the parents of FD children.

A slight virus in a healthy child can cause a "crisis state" in an FD child. Even a strong emotional episode can trigger an FD crisis. When a child goes into a typical crisis, the child severely retches, his or her blood pressure soars to 200/150 and the child's heart rate skyrockets to 180. Each time the parent wonders if this time his or her child will die.

Today, when a child goes into "crisis" parents step in as their child's advocate in the emergency room. They try to help the local doctors understand the affects of FD. A good situation is one where a doctor has the common sense to listen to the parents; an unproductive one is when the doctor does not listen. The latter can make matters worse for the child, the results, devastating.

Common medication can be lethal for FD children, so their parents check and double-check everything before administrating it to their children.

Administration of a common vaccine to an FD patient can trigger a crisis.

Since FD is rare, and many of the affected families live far from each other and FD medical centers, these families feel alone and helpless when a crisis occurs. Hope and support is shared through e-mails and phone calls with other FD-affected families. Faced with difficult decisions, like an operation, FD families have only each other for advice and experience.

FD Hope supports the work of Dr. Berish Rubin, a researcher at Fordham University in the Bronx, New York. Dr. Rubin identified the FD gene which will allow testing to determine FD carriers and hopefully prevent future cases of FD. Through his research, Dr. Rubin fights a daily battle to uncover new possibilities for an FD cure. Researchers are on the brink of discovering meaningful treatments that will halt the progression of the disease.

Until then, parents and children do their best to cope with the life-threatening challenges of FD.
