In late November 2007, we received a report from Dr. John Shoffner in Atlanta. We took Roxie to meet with Dr. Shoffner in August of the same year, and he used tissue from a muscle biopsy, spinal fluid, and blood samples for the workup which would determine if Roxie had a Mitochondrial Disease. The report read like Greek to us, and we didn't realize (since we aren't neurologists or biology experts) what it meant for Roxie until recently. While
Roxie was in the Pediatric ICU in January of this year -- to treat RSV and pneumonia that triggered breakthrough seizures -- a doctor there (the fabulous Dr. Johnson) read the report and explained to us that Roxie apparently does have Mitochondrial Disease (Complex I and III) and consequently we learned a little about what that means. We have not had a follow-up appointment with a specialist, so thus far all of our information has come from Dr. Johnson, from Roxie's neurologist Dr. Nelson, from researching online, and from parents of children with Mitochondrial Disease ... so I will do my best to explain what we know. While we are on a waiting list to find out when we can meet with Dr. Shoffner again (the best they can tell us is "by this summer" ... and yes, this is extremely frustrating), we hope to take Roxie to meet with another mitochondrial specialist, Dr. Bruce Cohen, at the Cleveland Clinic in April who can help us further understand Roxie's diagnosis and how the disease may affect her in the future.

The following explanation was copied from the
United Mitochondrial Disease Foundation's website.
Mitochondrial diseases result from failures of the mitochondria, specialized compartments present in every cell of the body except red blood cells. Mitochondria are responsible for creating more than 90% of the energy needed by the body to sustain life and support growth. When they fail, less and less energy is generated within the cell. Cell injury and even cell death follow. If this process is repeated throughout the body, whole systems begin to fail, and the life of the person in whom this is happening is severely compromised. The disease primarily affects children, but adult onset is becoming more and more common.
Diseases of the mitochondria appear to cause the most damage to cells of the brain, heart, liver, skeletal muscles, kidney and the endocrine and respiratory systems.
Depending on which cells are affected, symptoms may include loss of motor control, muscle weakness and pain, gastro-intestinal disorders and swallowing difficulties, poor growth, cardiac disease, liver disease, diabetes, respiratory complications, seizures, visual/hearing problems, lactic acidosis, developmental delays and susceptibility to infection.
--------------------------------
That is a basic explanation of general Mitohondrial Disease. However, there are currently 50 known types of Mitochondrial Disease and each case is different. We know that Roxie has defects in Complex I and Complex III within her mitochondria. I have learned that there are five complexes that take place within the mitochondria and each one takes part in the production of ATP which is what the body uses for energy. We now believe the disease has caused Roxie's low muscle tone, epilepsy, developmental delays, and sensory integration disorder and has left her body in a fragile medical state. We hope to learn more about her specific case when we meet with Dr. Cohen at the Cleveland Clinic in April. I mailed Dr. Cohen information about Roxie's medical history as well as the results from Dr. Shoffner's office.
Currently there is no cure for Mitochondrial Disease. There are a few treatments which have shown the potential to slow the progression of the disease in some patients. Roxie is now taking CoQ10 and Carnitor supplements to try to treat her disease and the hope is to prolong the life of her cells. There is a lot of research going on right now that could potentially help Roxie in the future. So we have hope and we are so blessed each day that we have Roxie with us and in good health.
