Brenna’s Battle With Tuberous Sclerosis Complex (TSC)

brenna and tuberous sclerosisBrenna Kahlen was born with much anticipation in August of 2001. Our family had been blessed with a boy nearly two years earlier and we were thrilled to have a little girl too.   For a time life was perfect.  At about two months of age, Brenna began ‘twitching’ on her left side.  The ‘twitching’ didn’t sound serious to Brenna’s pediatrician so we decided to wait and see if Brenna would grow out of it.  By five months of age the ‘twitching’ had increased so much, we set up an appointment with a Neurologist.  We got the first available appointment four months away.  We would never make it to that appointment.

Despite the ‘twitching’, we were not overly concerned since Brenna seemed to be a normal, happy, healthy baby.  At Brenna’s six-month well baby visit it became apparent that something was amiss.  Brenna’s abdomen was distended and she was not gaining weight as she should.  An ultrasound revealed cysts in her kidneys.  Sitting in the Nephrologist’s (kidney doctor) office one month later we learned that the cysts in Brenna’s kidneys were causing her to have terrifyingly high blood pressure.  At not quite seven months of age, Brenna’s top blood pressure number was well over 200—something that would have killed an adult.  She was admitted directly to Children’s Hospital of Orange County (CHOC) from the office visit and that is when our nightmare really began.  Once we were in the Pediatric Intensive Care Unit, the doctors started asking questions. Was Brenna rolling over and sitting up?  Did she ever have seizures?  Did she have a light colored birthmark?  Did we know she had a heart mummer? Then the tests began.  First we had an EEG, then an Echocardiogram, an EKG, an MRI and a chest x-ray.  All the while the doctors were trying to bring Brenna’s blood pressure down.  I thought my baby was dying.  As the test results started coming in we finally got her diagnosis:  Tuberous Sclerosis.  Although we finally had a name for the medical problems Brenna had, we didn’t understand it.

Tuberous Sclerosis Complex (TSC) is a genetic condition and everyday in the United States two children are born with it. On August 15, 2001, one of those two children just happened to be our Brenna.  There are more than 50,000 people in the United States with TSC and more than one million worldwide.  Nevertheless, TSC is considered rare and there is no cure.  TSC is the leading genetic cause of epilepsy and the second leading genetic cause for autism.  Behavioral issues are of serious concern and TSC individuals have a much higher rate of attention deficit disorder (ADD), bi-polar disorder and obsessive-compulsive disorder (OCD).  There are more people with TSC than Cystic Fibrosis, Lou Gerhig’s disease (ALS) and Hemophilia, yet most people have never heard of it.   Of more concern, many doctors and nurses have only read about TSC and have never encountered a patient with this disorder.

Today, we know that the ‘twitches’ Brenna was having were actually seizures.  Since they began when she was two months old, those seizures have grown in intensity and frequency.  Thus far we have been unable to control Brenna’s seizures with medication.  We are currently trying yet another medication and are considering a special diet to try and stop the seizures.  Unfortunately, if her seizures continue Brenna may have to undergo brain surgery.  While very frightening, this is an important option since controlling the seizures is essential in keeping Brenna on track developmentally.

The cysts in her kidneys cause her kidneys to be 4 to 5 times their normal size and make something as simple as getting clothes difficult.  Eventually, the cysts that are in her kidneys will take over all of the healthy tissue and she will need a kidney transplant.

Not all the news is bad.  Brenna is developmentally on track at this point, for which we are very grateful.  Many of the behavioral issues have never manifested nor did the autism. This could change at any time, but we try to focus on the here an now.  And the here and now keeps us busy enough. Brenna’s TSC manifestations require that she be monitored on a regular basis for any significant changes.  MRI’s, EEG’s, EKG’s, echocardiograms and ultrasounds are a regular occurrence for her. Brenna’s medical condition requires the involvement and cooperation of many medical professionals.  At this point, Brenna’s current medical team includes 8 pediatric specialists: a neurologist, cardiologist, ophthalmologist, nephrologist, neurosurgeon, endocrinologist, dermatologist and an orthopedist.  Unfortunately, we know that this list is only going to get larger as time goes on.

Brenna’s future is uncertain. TSC is in every cell and can affect every major organ in the body.  It is effectively described as a “shot gun blast” to the system.  Right now, in addition to brain tumors (cortical tubers scattered throughout her brain and subependymal nodules in her ventricles), Brenna has about a 20% risk for developing a giant cell astrocytoma (SEGA) that can grow and block the flow of brain fluid and almost always requires emergency brain surgery.  Brenna has heart tumors (rhabdomyomas) and small white patches on her skin (hypomelanmic macules) as well as a shagreen’s patch (a tough dimpled patch of “orange-peel like” skin) on her lower back. If you look closely you can begin to see the early signs of the disfiguring tumors (angiofibromas) that will grow on her beautiful little face and will eventually require laser surgery.  Brenna also has optic nerve involvement, which may affect her eyesight as she ages.  Since Brenna is female she has a 40% chance of developing a progressive lung disorder (lymphangioleiomymatosis or LAM) in her 30’s and 40’s.  LAM is considered fatal at this time.

You can see why we are very concerned for Brenna’s future.  However, no one in our family will ever lose the hope that we have for Brenna and we won’t accept this terrifying disease without a fight.  We are involved with the Tuberous Sclerosis Alliance of Orange County (TSAOC).

This organization has three main functions:

  1. A monthly support group for those affected by TSC
  2. An outreach and awareness arm whose goal is to help raise awareness within the medical community
  3. And a fund-raising arm whose goal is to help raise funds to maintain our local group and contribute to the research efforts of our national organization, the TS Alliance.

But we still need help!  We need to get the word out about Tuberous Sclerosis.  With public awareness of the disease, we can work on getting funding to help find a cure. For more information about Tuberous Sclerosis Complex, please visit www.tsalliance.org.

  1. Your story speaks to me in so many ways. My daughter is 2 1/2 years old and she was diagnosed with TSC at one month old. I know what you went through, we went through it to. I know the pain of the unknown and the dirty word “future”. Your family is beautiful! Brenna is amazing! I hope and pray for you and your family every day! I am fighting along with you guys. I hope that one day we will have more answers and know more about how to fight this. It would be a dream come true if there was a cure! Hugs to you and your family! Lily (my daughter) sends big sloppy toddler kisses too!
