Feeling defeated

I don’t know what is wrong with me.   I’m feeling very defeated and am worried tremendously about Hannah, specifically losing her.   I have no idea what set it off either.  

Today was a positive day.  Had a great, great conversation with two of the directors of the National Gaucher Foundation PLUS finding out they gave us a full-page share in their quarterly newsletter (click here, page 17).  Made some wonderful connections in the Tay-Sachs community.  Got a positive response from someone I was hoping, hoping would be able to help me understand what research is going on even though she is incredibly busy.  Found a couple GD2 and GD3 parents who are very willing to get more involved and “fight” with me.  Gosh, even more positive responses to emails I have sent out…many people willing to share their expertise to help me understand.

I just got this overwhelming feeling today that it may not be enough.  That no matter what I do, I’m not going to be able to save her, and I am going to lose her.  I haven’t felt like this in a long time, but I just feel like everything that is out there is just not going to be ready in time for Hannah.  That the treatment or cure will come after it is too late for us, for our family, for our little girl.  That because of our personal financial crisis as well as this so-called “recession,” there won’t be enough money to give Hannah everything she needs to keep fighting (especially if we have to come up with out-of-pocket money for additional therapy services) or money to give researchers who are working specifically on GD2 and GD3 research and treatments.

I watched Chuck tonight, and there was a scene where Chuck’s sister was getting married and being walked down the aisle with Chuck and their dad.  All I could think about was Hannah possibly never getting a chance to get married and have Daddy walk her down the aisle.  Would she even be here for her sister’s wedding or her brother’s?  

I watched that episode with Hannah cradled in my arms, asleep.  I just kept stroking her hair, giving her kisses on the top of her head.  I kept telling her that I love her.  I gave myself until the end of the episode before putting her into her bed.  I don’t know what came over me today (through tonight), but I don’t want to let her go. 

Tomorrow we have her NeuroOpthalmology appointment to see how much damage her Gaucher’s Disease has actually done to her eyes.  Another reality check.  Finding out the damage that will never be able to be repaired.  Finding out her limitations as of today and understand what limitations she may have in the future.

I don’t want to ask “Why Hannah?”   I don’t want to hear that “God has a plan.”  I just wish that she could just be a normal baby girl, and we could live a normal life.

More Therapy?

After receiving Hannah’s 8-month DAYC assessment, our pediatrician recommended adding some private therapy to Hannah’s regimen.  Our goal is to teach Hannah as much as we can now so it will take longer for her to lose what she knows once the disease progresses.  Also, since she is somewhat delayed in some important areas, it is important for us to keep working on getting her as caught up as she can.

He set us up with TCH’s therapy department, and fortunately, they have a clinic up here in The Woodlands so we don’t have to drive downtown.  We have three separate evaluations, one in May, and two in June – for PT (physical therapy), OT (occupational therapy), and ST (speech therapy).  Once we meet with them, they will give us their recommendations as to what they suggest, and we will work with our pediatrician to come up with a balance between the private therapy and ECI.

I have to talk to the TCH therapy department this week, however, to find out how our insurance covers this type of service.  Our bills for our bi-weekly Cerezyme have been coming in, and our part averages about $580 every two weeks (the bill originally is about $15,000 every two weeks).  It is killing us.  I just hope the therapy is covered more fully.

Happy 9-month birthday baby girl!

Dearest Hannah,

What an amazing milestone we have achieved.  Today, you are 9 months old. 

I took advantage of cuddling with you yesterday afternoon.  No one was home but you and me.  We just lied on the couch, you cuddled up against my side.  You played with my hand, my necklace, and my arm.  You just stared into my eyes at times, and I could feel the love and bond between us.   It is like nothing else in the world exists – no medical issues, no chaos…it is just you and me, together.  No video, no picture, nothing can really capture these precious moments between us.  Just you and me.  Then, you started drifting off to sleep, caressing my arm so softly as you were dozing off.  Then, right before you fall asleep, you give me the sweetest little grin.  I melt.

You have me not only wrapped around your finger, but you have my heart entangled with yours.   I love watching you sleep.  You look so peaceful.  Even moreso, I love it when you wake up and see me for the first time.  Wow!  Such a huge grin.  It is almost as if I feel like I’m exactly what you wanted to see when you finally do see me. 

We are still fighting for you, my little girl.  Rest assured I am leaving no stone unturned in my quest to do whatever I can to save your life.  I am determined to make you “different,”  not a victim of this disease, but the child who will survive this disease and live a happy life.   A child pioneer who will help lead other children affected with this horrific disease to also be able to live happily and share their love with their families.  

Your health is doing much better than we were told to expect at this point.  Most people don’t even notice that you are sick with this crappy disease when they meet you.  To everyone else, you just a very happy and smiling baby girl.  I am not naive to know that the disease has already started affecting you to some extent.  We do have some delays to work on, but at this point, they are just “the way it is” and you are learning at your own pace.  I love the freedom your body is still allowing you to have at this age and that this disease has not progressed enough to start slowing you down.  You are so much more of a fighter than I ever have been!

Though I pretend to be jealous, I just love how your brother and sister can make you laugh more often and harder than I ever could.   Seriously, you just see one of them smile at you, and you get so excited that I can feel your body jump up and down!  They are obviously your favorite toy because you can’t seem to get enough of their attention.  Fortunately, they love giving you every bit of that attention as well.

You have so fully integrated in our lives now that I just don’t even want to think about our lives without you.  You have already make a permanent mark in our hearts, moreso than I thought was possible in just 9 months.  9 months, and my life has completely changed.  Wow…

I promise to keep fighting for you, and you have to promise to keep fighting for you too.  I will talk to every specialist, every researcher, and every person even associated with this type of disease if that is what it takes to find the pieces of the puzzle that, when finally put together, will give us some peace in our lives knowing that the threat of losing you will be gone. 

That is my wish… Just to be able to live with you, your brother, your sister, and your daddy without worrying that you will be taken away from us so soon. 

I love you, my dearest little Hannah. 

Mommy

What the hell? THREE new GD2 kids, just not right!

In the past month, I have been contacted by three families of children who have recently been diagnosed with Gaucher’s Disease type 2, the fast progressive form.  It breaks my heart that there are more babies even a bit younger than Hannah is now going through this hellish disease.  

There is one family that I have come to know over the past few months who has a son just under 2 years old.  He is just a gorgeous little boy!  Unfortunately, they had recently retyped his classification from type 3 to type 2 due to an updated DNA sequencing, I understand.  After talking to his dad, I was friggin’ PISSED OFF that this was possible!  Type 2 only has a life expectancy of “up to” 2 years old!  This baby boy was already almost there.  I spent that entire afternoon angry and doing whatever I could to find information on researching or just anything.

There is so little out there research wise for our kids.  It sucks.  There has to be a way to change this.  I will FIND a way to change this. 

We still don’t know if Hannah has type 2 or type 3.  Last we were told by Dr. Schiffmann, Hannah’s neuro, that it looked like it could be a “slow type 2” or a “severe type 3.”  She is the “unknown” Gaucher’s baby.

Please keep these families in your thoughts and prayers.

Discovery of new gene that stimulates the release of calcium in cells

Discovery of new gene that stimulates the release of calcium in cells

International research collaborators have identified a new family of proteins, TPC2 (two-pore channels), that facilitates calcium signaling from specialized subcellular organelles.

The study, published today in Nature , is the first to isolate TPC2 as a channel that binds to nucleotide nicotinic acid adenine dinucleotide phosphate (NAADP), a second-signaling messenger, resulting in the release of calcium from intracellular stores. According to the researchers, this new discovery may have broad implications in cell biology and human disease research.

“The discovery was the result of many researchers working as one international team toward a unified outcome. We are very appreciative of all the collaborators’ efforts,” said Jianjie Ma, PhD, professor of physiology and biophysics at UMDNJ-Robert Wood Johnson Medical School. “We are proud to be part of a study that will stand as the foundation for further exploration of human disease, helping researchers to better understand how calcium contributes to cell growth and disorders, including aging-related cardiac disease, diabetes, lysosomal cell dysfunction and the metastasis of cells in cancer.”

According to the researchers, the mechanism for how NAADP triggers the release of calcium, as well as the specific sites of calcium store targeted for release, were previously unknown. These findings indicate that NAADP, through its interaction with TPC2, targets a specific store of calcium in lysosomes, a specialized subunit within the cell that contain digestion enzymes and regulate cell function.

The study was a collaboration of investigative teams at four universities, including the laboratory of Dr. Michael Zhu at the Ohio State University, the laboratory of Dr. A. Mark Evans at the University of Edinburgh and the laboratory of Dr. Antony Galione at the University of Oxford.

The research was supported by grants from the United Kingdom’s Wellcome Trust and the British Heart Foundation, the United States’ National Institutes of Health, and the American Heart Association.

New information on molecular biology of KRas protein

New information on molecular biology of KRas protein

KRas is one of the usual suspects in cancer. It is a protein that is mutated in 30% of human tumors and has been implicated in the regulation of many cell signalling pathways.

For this reason, it is one of the main focuses of attention of international basic research and it is difficult to publish new information relating to its molecular biology. Researchers from the Institut d’Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS) and the University of Barcelona (UB) have discovered a new breakdown pathway for this protein. The results, which could mean a new form of signalling involving KRas, were published in the latest edition of the Journal of Cell Biology (184(6):863-79), where they merited an appearance on the front page of the journal and an editorial comment. This study is part of the doctoral thesis of Dr. Albert Lu and includes the participation of Dr. Oriol Bachs , Dr. Carles Enrich , Dr. Neus Agell and Dr. Francesc Tebar , researchers from IDIBAPS and the Department of Cell Biology, Immunology and Neuroscience of the Faculty of Medicine of the University of Barcelona. Researchers from the University of Kyoto also took part in the study.

The article describes how the KRas protein is actively transported from the cell membrane, where most of its known activity takes place, to the lysosomes. The lysosomes are organelles responsible for breaking down proteins; this breakdown pathway was unknown in the case of KRas. Thanks to videomicroscopy techniques using a confocal microscope and the fluorescence, resonance energy transfer (FRET) technique, the researchers have observed how the protein is brought inside the cell and transported to the lysosomes. The protein remains active during this journey through the interior of the cell, which leads to the suspicion that it continues to exercise its influence on signalling pathways relating to cell proliferation and the appearance of cancers.

The signalling pathways activated by KRas are highly complex. With the newly available data, it will be necessary to investigate whether the signals emitted on the way to the lysosomes have a different meaning for the cell than those generated from the membrane, the protein’s usual site of action. These results provide clues to stimulating the elimination of KRas, a line of research that might result in new therapeutic strategies against cancer and diseases in which the formation of lysosomes is abnormal, such as Niemann-Pick disease. KRas is already used in the diagnosis of diseases such as colon, lung and breast cancer. The better we understand its biology, the more we will know about how it appears and how this and other diseases can be combatted.
