So Iga Means...

So my gastroenterologist tells me my blood levels are "slightly abnormal" and he says having an Transglutaminase IgA reading of 21 is also "slightly abnormal." So I assume this means I'm still getting a little gluten SOMEWHERE after starting my gluten free diet in November 2010. He also said the blood readings and the celiac are "two separate issues." Dumb me, I didn't press him so I'm confused.

Then my primary care doctor looked at the same 11 blood tests a couple days after (for my regular physical) and said he (my regular doctor) would consider the blood work "normal" and to give things "a little more time," I assume to readings to drop back into the normal range.

I do remember seeing an IgA reading on one of the blood tests last May and it was 46...and now it's at 21. Does this IgA reading reflect the healing of the intestines over time (like the condition is disappearing) OR is it an instant indication that I'm still ingesting gluten somewhere.

Plus I don't understand why the specialist would tell me my blood reading and the celiac condition are "separate issues." I had been drinking hard cider as my only alcoholic beverage of choice up to that appointment, after which the specialist asked me to refrain from all alcohol for about 4 months (till my next scheduled blood tests/follow-up appt).

The only things I see that are out of the regular range in the blood tests are (and there were a lot of tests): RDW-CV 19.1 (15.0 is the high normal), Platelet Count 149 (150 is low normal) and Mono% 14.7 (12.0 is high normal). The specialist has told me my liver levels are "spot on." I had a serious liver problem develop out of the blue, which is what started me on my road to needing this forum in the first place.

I feel fine, my weight is stable but I'm about 20 pounds lighter than I was pre-celiac. I suspect most of that was beer weight!

I know that's a lot of information but it's been on my mind an awful lot. If I'm still getting gluten I can't imagine where; I read a lot about it and am strict about the diet. If there's something else he might be monitoring regarding my blood work, I want to understand that, too.

Wish I could be of more help, any info I give you is what I can glean from online sources.

Firstly, IgA is not the same as transglutiminase IgA. Open Original Shared Link tells the difference; transglutiminase IgA is probably best to be known as tTG. So if you're only seeing part of the tests, or the doctor's mumbling the results, you don't remember exactly what they said, etc, there's multiple measures involving IgA. So, this probably is just complicating things for you, not clarifying them...

In any case, when I read up about antibodies in general online, you'll keep the ones you have for life, in some quantity or another. So the fact that you have some isn't unusual at all. It's really hard to find how long antibodies will stay elevated after the thing that causes them to elevate is gone.

Open Original Shared Link

Not sure I like everything on this page, but it does go into an explanation about IgG and IgM. IgG ones will remain elevated forever, while apparently IgM ones won't. Obviously IgA is neither of these, but it might not be so cut and dry as to how long they will last after eating gluten.

People and doctors say it takes awhile for celiac disease to heal properly from it, and if you ingest gluten even 6 months ago, you still might be having effects of it. That seems like an indication that elevated levels of IgA or tTG could easily last for 6 months. However, it's not clear to me if that's because of the antibodies, or if it takes intestines that long to heal once being attacked, or if its that long to regain vitamins or something.

I don't understand how/why IgA or tTG wouldn't be related to your celiac, however, I also don't know if they're markers for any other disease. I do know that some form of IgA is also involved in a specific kidney problem...I'm assuming it's again another slightly different form of IgA though, hopefully unrelated to celiac disease, but I don't know. I suppose they do also say you have to be eating gluten everyday for quite awhile for the blood tests to show up positive, so that probably means something too.

I really can't answer if this means you've eaten gluten recently or if it's residual. However, I would take it as a good sign that it's down, I would ask the GI next time how IgA levels might be related to something else besides celiac disease. Also, the fact that you had liver problems due to celiac disease means you must have had it pretty badly (I haven't had liver issues yet I've shown clear celiac symptoms for 6 years, and I suspect I've had it more like 12 or 13), so maybe that just means your personal IgA and tTG hang around longer than they do for someone like me.

If you are still not feeling well since going gluten-free is when I would be concerned about it.

Hello and thanks for the reply.

My liver problem 16 months ago was significant and what started everything... over about a month's time I had been COMPLETELY exhausted, lost 25 pounds and went jaundice. Spent five days in the hospital while they took all sorts of pictures but found no tumors in the places they looked. I was on complete bed rest for five weeks. It looked like a hepatitis but I was negative for all of those. The specialist has repeatedly told me how unique and difficult my case was to properly diagnose because it looked like a liver autoimmune disorder but, once he suggested I "try" a gluten free diet, the scary bad readings all started to recover...then the liver and intestinal biopsies and all to confirm celiac. He said he was very close to diagnosing something very different which would have put me on steroids maybe for life...and in the end would not have addressed the gluten intolerance anyway.

What I'm left with now is the subject of this thread, some blood readings that are "slightly abnormal" after about 16 months. But I truly feel fine, I'm no longer anemic and, although I'm thinner than I used to be (since there's no more beer weight) the only indication there is something wrong is this doctor telling me there is. But not alarming enough for him to follow up less than every four months.

Since January (the follow-up visit I've been referring to) I have eliminated I think the last possible sources of hidden gluten or cross-contamination in my diet...AND all alcohol to try and put the blood work back into "spot on" territory for my next follow-up in May.

I'm single and ate out a lot at a BW3 across the street...I ate only their couple gluten free offerings but I think I was getting cross-contaminated and stopped eating there. I cut out ordering bacon also when eating out for breakfast, I thought that might also be a source of hidden gluten. We'll see in May if I was right. Otherwise I'm strict and eat the things I've found on this board or whatever is labeled gluten free.

I just want to get that "two thumbs up" follow-up appointment I haven't had yet. Then I guess the last step is the doctor is going to do one more biopsy to make sure the villi have recovered, did I understand that right? I think he said we're not ready for that yet.

I'm the first person in my family with Celiac; nobody knew anything about it before me. They know plenty now.

      Outgrow celiac?

      I think your initial idea, eat gluten and be tested, was excellent. Now you have fear of that testing, but isn’t there also a fear each time you eat gluten that you’re injuring your body? Possibly affecting future fertility, bone health and more? Wouldn’t it be better to know for sure one way or the other? If you test negative, then you celebrate and g...

      @Riley., Welcome to the forum, but don't do it! Don't continue to eat gluten! The health problems that will come if you continue to eat gluten are not worth it.

      Outgrow celiac?

      @Riley, on this forum we sometimes get reports from people with similar experiences as you. That is, their celiac disease seems to go into remission. Typically, that doesn't last. At age 18 you are at your physical-biological peek in life where your body is stronger than it will ever be and it is able to fight well against many threats and abuses. As Wheatwacked...

      I think your initial idea, eat gluten and be tested, was excellent. Now you have fear of that testing, but isn’t there also a fear each time you eat gluten that you’re injuring your body? Possibly affecting future fertility, bone health and more? Wouldn’t it be better to know for sure one way or the other? If you test negative, then you celebrate and get tested occasionally to make sure the tests don’t turn positive again. If you test positive, of course the recommendation from me and others is to stop gluten entirely.  But if you’re unable to convince yourself to do that, could a positive test at least convince you to minimize your gluten consumption?  Immune reactions are generally what is called dose response, the bigger the dose, the bigger the response (in this case, damage to your intestines and body). So while I am NOT saying you should eat any gluten with a positive test, the less the better.

      @Riley., Welcome to the forum, but don't do it!  Don't continue to eat gluten!  The health problems that will come if you continue to eat gluten are not worth it.  Problems may not show up for years, but the constant inflammation and nutritional losses will manifest eventually.  There's many of us oldsters on the forum who wish they'd been diagnosed as early.    Fertility problems, gallbladder removal, diabetes, osteoporosis and mental health challenges are future health issues you are toying with.   To dispel fear, learn more about what you are afraid of.  Be proactive.  Start or join a Celiac group in your area.  Learn about vitamins and nutrition.   Has your mother been checked for Celiac?  It's inherited.  She may be influencing you to eat gluten as a denial of her own symptoms.  Don't let friends and family sway you away from the gluten-free diet.  You know your path.  Stick to it.  Be brave.

      @tiffanygosci, Hello.  I apologize for your thread being hijacked.   I recognize your symptoms as being similar to what I experienced, the migraines, food and chemical sensitivities, hives, nausea, the numbness and tingling, joint pain, tummy problems, sleep problems, emotional lability, and the mom brain.  My cycle returned early after I had my son, and I became pregnant again with all my symptoms worsening.  Unfortunately, I lost that baby.  In hindsight, I recognized that I was suffering so much from Thiamine deficiency and other nutritional deficiencies that I was not able to carry it.   Celiac Disease affects the absorption of nutrients from our food.  There's eight B vitamins that must be replenished every day.  Thiamine Vitamin B1 becomes depleted first because it cannot be stored very long, less than two weeks.  Other B vitamins can be stored for two months or so.  But Thiamine can get low enough to produce symptoms in as little as three days.  As the thiamine level gets lower, symptoms worsen.  Early symptoms like fatigue and anxiety are often attributed to life situations, and so frequently go unrecognized by medical professionals who "have a pill for that".   I used to get severe migraines and vomiting after gluten consumption.  Thiamine and the other B vitamins are needed to turn carbohydrates, fats and proteins into fuel for our bodies.  With a large influx of carbohydrates from gluten containing foods, the demand for Thiamine increases greatly.  Available thiamine can be depleted quickly, resulting in suddenly worsening symptoms.  Emotional stress or trauma, physical activity (athletes and laborers) and physiological stresses like pregnancy or injury (even surgery or infection) increase the need for Thiamine and can precipitate a thiamine insufficiency. Pregnancy requires more thiamine, not just for the mother, but for the child as well.  The mother's Thiamine stores are often depleted trying to meet the higher demand of a growing fetus.  Thiamine insufficiency can affect babies in utero and after birth (autism, ADHD).  Having babies close together doesn't allow time for the mother to replenish thiamine stores sufficiently.   Thiamine insufficiency can cause migraines, pins and needles (paresthesia), and gastrointestinal Beriberi (gas, bloating, diarrhea or constipation, back pain).   Thiamine deficiency can cause blurry vision, difficulty focusing, and affect the eyes in other ways.  Thiamine deficiency can damage the optic nerves.  I have permanent vision problems.  High histamine levels can make your brain feel like it's on fire or swelling inside your cranium.  High histamine levels can affect behavior and mood.  Histamine is released by Mast Cells as part of the immune system response to gluten.  Mast Cells need Thiamine to regulate histamine release.  Mast Cells without sufficient thiamine release histamine at the slightest provocation.  This shows up as sensitivities to foods, smelly chemicals, plants, and dust mites.  Thiamine and the other B vitamins are needed to lower histamine levels.  Vitamin D is needed to calm the immune system and to regulate our hormones.  Menstrual irregularities can be caused by low Vitamin D.   Celiac Disease is a disease if Malabsorption of Nutrients.  We must take great care to eat a nutritionally dense diet.  Our bodies cannot make vitamins.  We must get them from what we eat.  Supplementation with essential vitamins and minerals is warranted while we are healing and to ensure we don't become deficient over time.  Our bodies will not function properly without essential vitamins and minerals.  Doctors have swept their importance under the rug in favor of a pill that covers the symptoms but doesn't resolve the underlying issue of malnutrition. Do talk to your doctor and dietician about checking for nutritional deficiencies.  Most blood tests for the eight B vitamins do not reflect how much is available or stored inside cells.  Blood tests reflect how much is circulating in the blood stream, the transportation system.  Blood levels can be "normal" while a deficiency exists inside cells where the vitamins are actually used.  The best way to see if you're low in B vitamins is to take a B Complex, and additional Thiamine and look for improvement.   Most vitamin supplements contain Thiamine Mononitrate, which is not easily absorbed nor utilized by the body.  Only thirty percent of thiamine mononitrate listed on the label is absorbed, less is actually utilized.  This is because thiamine mononitrate is shelf stable, it won't breakdown sitting on a shelf in the grocery store.  It's so hard to breakdown, our bodies don't absorb it and can't turn it into a form the body can use.  Take Thiamine in the form Benfotiamine or TTFD (tetrahydrofurfuryl disulfide) which the body can utilize much better.  (Ask for an Erythrocyte Transketolace Activity test for Thiamine level.  Though not accurate, this test does better picking up on a thiamine deficiency than a blood test.) Are you keeping your babies on a gluten free diet?  This can prevent genetically susceptible children from developing Celiac Disease.   P. S.

      @Riley, on this forum we sometimes get reports from people with similar experiences as you. That is, their celiac disease seems to go into remission. Typically, that doesn't last. At age 18 you are at your physical-biological peek in life where your body is stronger than it will ever be and it is able to fight well against many threats and abuses. As Wheatwacked pointed out, absence of symptoms is not always a reliable indicator that no damage is being done to the body. I was one of those "silent" celiacs with no symptoms, or at least very minor symptoms, whose body was being slowly damaged for many years before the damage became pronounced enough to warrant investigation, leading to a diagnosis. By that time I had suffered significant bone demineralization and now I suffer with back and neck problems. Please, if you choose to continue consuming gluten, which I do not recommend, at least get tested regularly so that you won't get caught in the silent celiac trap down the road like I did. You really do not outgrow celiac disease. It is baked into the genes. Once the genes get triggered, as far as we know, they are turned on for good. Social rejection is something most celiacs struggle with. Being compliant with the gluten free diet places restrictions on what we can eat and where we can eat. Our friends usually try to work with us at first but then it gets to be a drag and we begin to get left out. We often lose some friends in the process but we also find out who really are our true friends. I think the hardest hits come at those times when friends spontaneously say, "Hey, let's go get some burgers and fries" and you know you can't safely do that. One way to cope in these situations is to have some ready made gluten-free meals packed in the fridge that you can take with you on the spot and still join them but eat safely. Most "real" friends will get used to this and so will you. Perhaps this little video will be helpful to you.
