Yet another question - significance of elevated anti-cardiolipin antibodies

Hi again,

The more I read, the more questions I have. You've all been so helpful, so here's another one.

Just to recap - my husband has been on Rebif since July. His last MRI showed several new spots immunologic activity. The neurologist now wants to switch him to Tysabri.

My husband also has very elevated anti-cardiolipin antibodies which the neurologist seems to think is significant and may be the related to his particular presentation of MS, though I didn't catch his explanation, I was a little overwhelmed when I spoke with him.

From my reading, it seems that about 15% of pts with MS have this. Does anyone have any idea what the significance of anti-cardiolipin antibodies are?

Thanks so much for all your help!

Hi jois,

I was tested at the Lupus clinic in London for this antibody.
The consultant thought i might have Hughes syndrome because this desease can cause some neurology disturbance.


Does he having clotting problems?
I bleed alot if I have tooth removed or bump myself.


Hope you get sorted soon take care tarter








Mine were normal again these are all autoimmune problems.

Well now,,, this is a difficult question, but I'll see if what I know and have found out can help.

First, elevated titers of the Anti-cardiolipin antibody can be found in about 1% to 5% (depending on the study) of the general population.   In people without problems from it the level is not particluarly high, usually less than 40.  It doesn't necessarily mean disease.  HOWEVER, in the presence of illness and many symptoms, it may be the clue to a correct diagnosis.

This Syndrome can cause the formation of tiny clots which can form in almost any organ.  Especially they can cause CNS symptoms that look just like MS.  However, since the lesions are not from an immuno-inflammatory cause the CSF is typically negative.

One of the closest mimics of MS is the Anti-Phospholipin Syndrome (APS also includes the Anti-Cardiolipin antibody), also known as Hughes Syndrome.  This is commonly referred to also as "Sicky Blood"  where the tendency to clot is too high from any one of a number of factors (like Anti-Cardiolipin Antibody).  A common misdiagnosis of of MS is often given to these people.  In fact, one large study at a large MS Clinic found that almost 20% of the MS carrying the MS diagnosis actually had Hughes Syndrome instead!!!

Now, I found the same articles that you probably did that carrying the Anti-Cardiolipin antibody is a subset of MS patients.  This was written up by a group of researchers in the Middle East about 8 years ago.  It was never verified by other researchers that I found.  I suspect that these researchers were actually describing a misdiagnosed group of people with Anti-Phospholipid Syndrome and NOT MS.

My concern regarding your husband (and not knowing ANYTHING about his workup) is that he might have a hypercoagulable state and NOT MS.  There are a large number of things that would need to be checked for to determine whether or not his neuro symptoms are due to a form of APS (Hughes) and not MS.

The things that should be checked - usually by a rheumatologist or hematologist are

The hallmark result from laboratory tests that defines antiphospholipid syndrome (APS) is the presence of antiphospholipid (aPL) antibodies or abnormalities in phospholipid-dependent tests of coagulation. In addition to the clinical criteria listed in History, at least one of the following laboratory criteria is necessary for the classification of APS:

-- Presence of LA (Lupus Anticoagulant) in plasma on 2 or more occasions at least 12 weeks apart (see below)

--Presence of moderate to high levels of anticardiolipin (aCL) (IgG or IgM) in serum or plasma (ie, >40 IgG phospholipid units (GPL)/mL or IgM phospholipid units (MPL)/mL or >99th percentile) on 2 or more occasions at least 12 weeks apart

--Presence of moderate to high levels of anti–beta-2 glycoprotein I antibodies (IgG or IgM) in serum or plasma (>99th percentile) on 2 or more occasions at least 12 weeks apart


aCL antibodies react primarily to membrane phospholipids, such as cardiolipin and phosphatidylserine. Of the 3 known isotypes of aCL (ie, IgG, IgM, immunoglobulin A [IgA]), IgG correlates most strongly with thrombotic events. Cardiolipin is the dominant antigen used in most serologic tests for syphilis; consequently, these patients may have a false-positive test result for syphilis.
************************

That info is from an eMedicine article from this year:

http://emedicine.medscape.com/article/333221-overview

Another list from the article lists several things in the patient's history that might suggest this over MS.

** Thus, history of any of the following should raise the examiner's suspicion for APS:

Thrombosis (eg, DVT/PE, MI, transient ischemic attack [TIA], or CVA, especially if recurrent, at an earlier age, or in the absence of other known risk factors)

Miscarriage (especially late trimester or recurrent) or premature birth (for women)

History of heart murmur or cardiac valvular vegetations

History of hematologic abnormalities, such as thrombocytopenia or hemolytic anemia

History of nephropathy

Nonthrombotic neurologic symptoms, such as migraine headaches, chorea, seizures, transverse myelitis, Guillain-Barré syndrome, or dementia (rare)

Unexplained adrenal insufficiency

Avascular necrosis of bone in the absence of other risk factors

Pulmonary hypertension

**********************

So, I do not think from my reading that the anti-Cardiolipin antibody in your husband is related to MS.  It is either coincidental or should be a direction that should be exhaustively looked at.  Also, it is rare, but possible to have both conditions, MS and aPS.

Does this help?

Hmmmm.....some here on the forum recently had a history of unexplained aeptic necrosis of a joint or two.  Does anyone remember who this was?  Was APS explored?

I left this out.  A nice, large study from 2002 did find that aCL was more common in MS, but their conclusion was that it was from the general activation of the autoimmune activity rather than indicating a true "subset" of MS patients.

I'll keep looking.

Hmmm...Ok well, definitely more questions to ask the neurologist and the neuro-immunologist. I'm pretty sure that APS was ruled out in the first round of tests. My husband doesn't have any of the symptoms that you listed.

This is his story in a nutshell: it started with a severe back ache which turned out to be a red herring that delayed diagnosis about 8 years. About 3 years later he had another bout of back problems during which he had a bad foot drop - don't remember which side, and his leg buckled under him twice. He was treated for a herniated disc in his back.

Sometime during the following year he started having the "jerking" at night which we later found out was the myoclonic spasms. He kept forgetting to tell his doctor despite my repeated urging.

About a year after that he started losing control of his bladder. The doctor gave him flomax and diagnosed a mildly enlarged prostate. The flomax did nothing for his problem.

After two years the problem got worse so he went to a urologist who found nothing wrong except for hypersensitive nerves and sent him to a neurosurgeon for his back.

The neurosurgeon found that the disc had ruptured but that the location of the rupture was no where near the nerves that innervate the bladder so he referred my husband to a neurologist.

The neurologist, who has been great by-the-way, did a slew of blood tests, MRIs, spinal tap, ruled out lupus, APS and ALS and a whole bunch of other autoimmune diseases, found elevated immunoglobulins - that were not elevated in the serum (can't remember IgG or IgM) and numerous plaques consistent with MS in his brain. There was also the elevated anti-cardiolipin antibodies but the neuro confessed that he wasn't sure what to make of it since all the other tests were negative for APS.

At this point my husband started Rebif.

Six months later he has new plaques with some of the old ones resolved

sorry - accidently pressed send - this is a continuation of the previous post...

Ok-just looked it up - his aCA was 28 - the blood report said it was "moderately elevated" but I guess it's not significant.

It's all so confusing...

It sounds like his neuro is on the ball.  That is great news for you.

Maybe he just has an elevated aCA and it is what we used to called:

True (he has elevated antibdy). True (he has MS). And Unrelated.
