Cytoxan and Mesnex

Smokie Darling (Annie) - 03 Dec 2005 01:35 GMT
Okay, so I've got an appointment to begin Cytoxan treatment for my RA
on 9 December.  Being the paranoid that I am, I check out the 'net for
information.  I get this warning:

Do not take this drug if you have Rhuematoid Arthritis (of course it
says talk to your doc first, but....).

Then I look up Mesnex (also known as Mesna), and get a very similar
warning.

Sooooo, I'm thinking to myself, "Self, we are getting worried about
this."  Seems that Cytoxan is toxic to the bladder, which is why I'm
infusing, rather taking orally or self injecting (that and I will be
getting a higher dose).  Then I'm told that I will be given Mesnex
before AND after the infusion to protect the bladder.

I'm wondering if anyone here is using Cytoxan and can give me a bit of
insight.  I know we are all different, but I'm curious.  I'm not
looking forward to the reduced appetite side-effect, though I suppose
it's better than the nausea and vomiting one (maybe the appetite
suppression is actually just a result of the nausea and vomiting?).

If this doesn't work, then I get the "joy" of just going onto a
maintenance "diet" of pain pills.  Rituxan gave me systemic hives (that
the RD thought/thinks might be vasculitis), Enbrel no longer works
(since I've had to stop using it so often, it just quit working),
Humira never worked, I'm allergic to Remicade (the best stuff I ever
used), I'm allergic to Prednisone (but CAN take hydrocortisone without
the headache, mood swings, weight gain, moon face, etc...), Arava
worked somewhat as did Methotrexate, but apparently my body didn't like
them (WBC below 2.2), the only thing I haven't tried was Kineret and
the RD doesn't think that would work for me (oh and Abatacept probably
won't either since I am not responding well to anti-TNFs anymore).
Here's hoping that something in the "pipeline" works well if this
doesn't.

I will only be allowed to be on it for 12 months (the hospital would
not even begin the process of registration until the doctor wrote them
a note saying I would not be on it longer than 12 months!!!).

I'm trying to be positive (no, not positive that it won't work, ya
sillies), but I'm getting a bit depressed.  I'm thinking that my
"vision" of myself in full-time care because I cannot care for myself
is getting closer, and I don't wanna (whine, whimper, cry).

So, if anyone knows about Cytoxan and Mesnex, can you drop a line.  The
email works.

I believe Cytoxin is a medicine that they use for "Wegener's" which is
listed as one of the arthritis family.  I have limited Wegener's but have
not used it.

Hello, Annie..  As you have limited Wegener's granulomatosis (WG), I
want to make sure that you're aware of the Wegener's Granulomatosis
Association in Kansas City, MO.  They have a web page at
www.wgassociation.org where one can download a 150 page "patient packet"
of information in Microsoft Word or Adobe Acrobat format.  For a hard
copy, contact the WGA at 1-800-277-9474 or wga@wgassociation.org

"Limited" WG merely means the person doesn't yet have kidney
involvement.  It is no less potentially dangerous than WG with kidney
involvement.

Cytoxan used to treat WG (and some other autoimmune vasculitides), but
in dosages much less than used to treat cancers.  Even so, it has
significant short and long term side effects which is why physicians try
to avoid it or limit the cumulative amounts.  It is likely to effect
fertility although there are strategies that may preserve fertility in
at least some cases.

Some safer immunosuppressives used to treat WG (that may not be as
effective) are ones you probably know about, Methotrexate, Cellcept,
Imuran, etc.

There's a wg-discussion email group at
http://www.weareb.org/mailman/listinfo/wg-discussion with several
hundred members.  Suscription is free.

Best wishe in you battle with WG and arthritis.

Hi Bruce
How are you?  It was me Lorrie F who was answering Annies Message.  I have
limited Wegeners But Annie was asking about the cytoxan to be used in
Rhuematoid Arthritis.  I hope I clarified that and didn't make it more
confusing.

Um, no, I do not have Wegener's.  I have RA, and I've gone through all
the treatments aside from this one.  Doc is a bit concerned that I
*may* have vasculitis, but I don't see it as the hives disappeared
after starting Hydrocortisone (and with vasculitis that would not have
happened).

Thanks for all the info, that does help me make a more informed
decision

Cytoxan is a drug used in bone marrow trasnplantation to wipe out the
bone marrow and immune cells. It was trialled as a treatment for
aplastic anaemia. The results were okay, but the death rate was higher
than expected, and it was discontinued.

Given what I've said above, what have they actually told you about this

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. Complications in
hospital following this resulted in a serious illness. I now need a bone
marrow transplant. Many people around the world are waiting for a marrow
transplant, too. Please volunteer to be a marrow donor:

Well, considering that I have no other options left, that might have a
chance of working, that's why we are going this route.

I'll be "labbed" (blood draw) 10 to 12 days after each infusion (to
check my WBC), and then evaluated after 90 days (by the RD).  I know
it's potentially very dangerous, but I believe the doctors are becoming
worried about organ involvement now.  So, die now, die in a year.  Hmmm
(not funny I know, but my DH wants me to try it as well, he says he
isn't ready to lose me just yet).

I have heard about the odd case of attempting bone marrow transplant for
those with severe, untreatable RA. Age and availability of family donors
are factors in the decision to transplant.

Odd that you should mention that.  My second RD and I talked about it.
He made the comment that it either works or the receiver dies (not sure
if he was joking or not).

We also discussed a treatment that is being done (on an experimental
basis maybe?) in Britain (sometime after 2000 I heard about it).
Apparently, there is a medical cure, but it causes cancer (not *might*
cause it, it does cause it) in like 10 to 20 years.  All the RDs have
said that if it comes to that, they would interview my husband and any
family members to make sure everyone knew and understood the
ramifications.

I'm hoping that it works, at least until something a little less toxic
comes up that may help me (I *can* still hope apparently).  I am
scared, but trying to remain positive.

You have been sooo informative, I really want to thank you for sharing
your knowledge with me (and everyone else too!).  I think that having
any info is better than having none (less stress on the head, ya
know?).

No joke. That's why I'm pushing as long as I can before going through
it, especially considering my donor is not a perfect match (and even
less so with the coming 12/12 matching standard for marrow).

I haven't heard of this.

Cytoxan is just about as toxic as you can get without going to chemo, if
I'm understanding correctly. You'll not be getting the kinds of doses
I'll be getting (where poeple literally bleed out through their bladder,
etc), but it can't be nice... I'm wondering why they don't use ATG/ALG,
like they do with autoimmune aplastic anaemia. I guess it just hasn't
been trialled yet. Cytoxan is a much older drug.

Abatacept seems to work well for anti-tnf non responders, it is not an
anti-tnf drug.  I would not rule this drug out.

If the biologic drugs had not come along I would probably have been on
Cytoxin but fortunately it is not used much anymore.  Good luck I was
extremely happy I never had to go on it.   Thank you Remicade!  Wish I
could give you more advice. -- MZ

Annie,
It is always so scary starting a new regime.  I am paranoid too and always
check the net.  Sometimes it isn't a good idea - especially if the
information isn't exactly to suit my situation.

The questions I ask myself now before starting anything - 1.  what will they
be monitoring and what will I do to ensure I follow that strict monitoring
regime.  2.  Do I trust my doctors to check the results religiously (I do in
my case and I have 2 doctors checking the results.  When on gold and
cyclosporine for example I also had to check with the doctor each week to
ensure that the results were okay.  Sometimes you need to put routines in
place to do this.  3.  Is there an option (which in your case seems limited
right now.

I know your worries about permanent care right now.  Everything is kind of
scary here too since my rd says no RA meds until all this is over (the ms
type reaction to the enbrel) and that it will probably take 6 months to a
year.  That is so scary as I am way too independent for my own good.  By the
same token I am determined I will make it through.  The important thing to
remember is there are all these new things coming down the tube and some
that you and I haven't tried - such as prosorba column maybe!  Hang in there
and if you ever want to talk I am here.

Hoping this treatment does the trick though.  But if you are in doubt don't
be afraid to ask for a second opinion.  Your RD might just welcome that as
well.
