What Could A Pos Blood Test, But Neg Biopsy Be?

14 posts in this topic

About a year ago, I was referred to a GI specialist due to IBS symptoms. I am quite sensitive to lactose but was being pro-active about my health and wanted to make sure there was nothing else wrong. The doctor routinely ran some blood tests and it came back as high in gliadin antibodies. (I'll have to check which test it was). Shortly thereafter I had an endoscopy to confirm the celiac diagnosis, but no abnormalities were found and the doctor said I wasn't celiac. My question is this though, what could the high blood test be if I have the symptoms, but no villious atrophy? Anyone know or have this same issue?

Thank you!

GEF

I have high Gliadin IgA not IgG.

I didnt want a biopsy, since I figured nothing was going to be there anyway. My Ttg was also totally negative, but that is the one test they have decided to run every few years to make sure I dont have full blown Celiac. Right now the most information I can gather is that it could be developing.

Maybe someone with more experience has more to share.

Hi GEF, welcome :)

There are several people here that have had positive blood test results and negative biopsy or vice versa. Heck... some of us had both negative test results and biopsy and still have Celiac/gluten sensitivity. Hang in there and I hope you get some answers soon!

Maybe someone will be along soon with more experience on the Celiac blood tests.

Thank you for your support. I have read so many of the posts and it does appear that many are in the same situations.. and many without the support of their doctor. I threw out gluten intolerant & celiac diagnosis when my doctor threw it out after the biopsy was normal. Looking back, I find myself disappointed that he didn't recommend gluten-free, especially when I hear how much damage can occur to your body if you are intolerant or celiac. He gave me the IBS diagnosis, which I can't seem to come to terms with. I was reading on EnteroLab's (enterolab.com) site that even someone with gluten intolerance can suffer malabsorption and all the celiac symptoms. I'm considering another dr's appointment to check for the level of malabsorption. I'm a frequent sufferer of "cloud-head", have many intestinal symptoms (diar, bloating, lactose intol), have clouds in my fingernails, poor teeth enamel, am borderline underweight. I would have to say the thing that bothers me the most is the "cloud-head" (there's nothing like feeling like that when you're paid to work well and productively) and if a gluten-free diet would cure that alone, it would be 100% worth it for me. I'm 28 and had GI symptoms for at least 13 years. Fiance is in total support of trying the diet and I'm finally to the point (after a year) where I can accept this.

(positive gliadin test, normal biopsy, IBS diagnosis)

I am in the same boat althought now they say "borderline celiac" whatever that means. I started to think about it and came to the realization that practically nothing healthy is made from wheat and there are better sources of fiber. Its all just "filler" food and if staying away makes me feel better than I am all for it.

You are welcome; this is a great place for support!

I too suffered for over a year and was given the famous IBS diagnosis; it should be called the IDK syndrome (I don't know) lol. I knew after losing 40lbs in 2 months that there was something more to it than the doctors could find. I went through all the conventional testing, emptying scan, colonoscopy, upper GI w/ follow through, endoscopy and CT scan. All of these came back normal with the exception of the endoscopy, which showed "patchy inflammation", but it wasn't enough to make a dx.

I finally decided to get tested through Enterolab and the $200.00 I spent for the tests was WELL worth it. I tested positive for gluten sensitivity and malabsorption due to intestinal damage. I immediately started the gluten-free diet and could tell a difference within a couple of days.

It is great that your fianc

I called a new GI this morning and got an appointment...this morning. Can you believe that? The new doctor was actually very kind and listened compassionately to my plight. I did find out that the test I took last year that was positive was IGG. It was 33, with normal levels below 20. Lucky me has lupus in the family so I have to get more bloodwork and a colonoscopy done :blink: Anyway, since the igg test above is about a year'ish old, the doctor ordered some new ones just in case. I really do wish I'd get better with something as simple (I know it's not simple) as a diet.... I'd just prefer that over meds! But, I'll let you know. Anyway, I'm just like everyone one of you that just won't be satisfied until they've exhausted being proactive about their health. When you know something's wrong, you know it's wrong.

Igg 33, everything else negative... who knows????

This may be hearsay, but my local celiac support group has discussed this topic (positive blood test, negative biopsy) a LOT. I also discussed rationale for doing blood tests and biopsies with my naturopath when I first suspected I had celiac. Here's what I understand about the blood test/biopsy disagreement phenomena:

The blood test indicates gliadin antibodies, but the biopsy shows damaged small intestinal tissue or flattened villi. Unless the patient has 100% of their small intestine damaged from longterm celiac, it's very possible that the biopsy tube can MISS the damaged area. Then it takes chunks of healthy tissue, rather than damaged tissue. So biopsies can be pretty hit and miss, unless a large percentage of the small intestine is damaged from long undiagnosed celiac disease. If you read Dr. Fine's speech under the Enterolab topic on this board (or just go to the Enterolab site), he also discusses the problems with biopsies.

I hope that helps. BTW I did the Enterolab tests for my diagnosis, after my naturopath explained how hit & miss the 'old' standard biopsies can be. :D

Burdee: Thanks for that explantion. What I dont get, most people with celiac disease have high IgG. Many have low IgA.

I have IgA only, and I have not found much literature at all to tell me what that really means. Dr. Fine said Gluten sensitivity only........

That is pretty interesting. I have lupus in my family as well and my GI didn't look twice at it. Also diabetes. I am curious as to what your new doctor says.

From what I've heard, having lupus in the family can mean your risks of celiac disease are also there as well. It's something about those auto-immune diseases that stick close together. The doctor requested some auto-nuclear test to pick up lupus today, so maybe that'll give some answers. Since the family history is there, it's worth checking out. Although the colonoscopy doesn't sound so pleasant, I'm wondering what it will show (I won't have that until 7/16). I have never had any GI issues associated with my stomach... just mid to lower intestinal. That positive IGG certainly makes me wonder. I just want to feel better though, I don't care what they have to test. Know what I mean?? And by golly, I won't stop until I get some answers... a trait that most of you here have... tenacity ;)

I'm also being tested for Lupus too, I show many signs of the disease. There has to be a link between these two diseases'.

Stacie,

I'd be interested to hear what your doc finds... I'll keep you posted from my end. I'm assuming I'll know something by early next week.

Gretchen,

I will let you know when/if I am diagnosed and yes please do keep me posted on your results as well.

All this started for me in January 04 and I've heard sometimes it can take months even years to be diagnosed. When I started feeling bad with the fatigue and other things I researched it on the Internet and it all pointed to Lupus, I went to my doc and explained my fatigue to him and he ran the ANA and it was POSITIVE! I was sort of scared and excited at the same time (if that makes ANY sense) ;) . You see with all this Celiac stuff all my test came back negative but I knew something was wrong and then these new things started happening and at least with the positive labs the doctors knew what path to take and in what direction to look at.

Anyway, let me know what your test show.

    • KathleenH, I swear by MatteosPizza and they make National Delivery. I have been known to buy them by the dozen. https://www.matteospizza.com/ BellaMonica's is not a bad corn based crust.  By not bad I mean "suprisingly good" that can be bought at most grocery stores. Here is there ZIP locator page to see if they are carried in your local area. http://glutenfreepizza.typepad.com/gluten-free-pizza/where-to-find-bella-monica.html I hope this is helpful. posterboy,  
    • Hey all--have Hashimoto's and am being worked up for epigastric discomfort and IBS like symptoms---   My blood work had an IgA within the lower end of normal range, negative TTG, but weakly positive DGP.   My endoscopy showed a "nodular" duodenum with the biopsy stating there was "reactive lymphoid hyperplasia"...   I have a follow-up with the GI in 3 weeks.   Wondering about any help?
    • DH wasn't linked to celiacs until 1967 from my research...
    • I was at a used book sale yesterday and happened to see an old dermatological textbook.  Of course the first thing I looked up was dh just to see what it had to say.  What I read shocked me as well as scared me half to death. The description of dh was right on, severe itching, blistering, bilateral, arms/elbows etc. but there was no mention at all of celiac, wheat, gluten or anything along that line.  The reason they gave for the cause of dh was "a manifestation of an internal cancer," and later it said it results from cancer, usually cancer of the ovaries or one other that I can't remember.  Being a hypochondriac, this was about enough to put me into cardiac arrest. I looked at the publication date and it was printed in 1963 which really isn't all that far back.  Has anyone else ever heard of this?? I thought by 1963 they were quite certain that dh was a form of celiac or did it come way after that? Sorry if I'm freaking anyone out by asking this.  That's not my intent at all, but since cancer is one of my biggest fears I found this rather unsettling.
    • Feeneyja, This will be a little long but I will  try to be brief as possible. See this discussion thread that talks about how Pellagra is often diagnosed as other disease's today because doctor's rarely recognize it today in a clinical setting. Pellagra's is described as the 3 D's if you don't count the 4th D of death if it goes long enough and is not diagnosed in a timely manner. Dementia (Neurological) Digestive (GI problems), Dermatitis issues (Ezcema, Psorsias, Acne etc.) According to mdguidelines website http://www.mdguidelines.com/pellagra indicates that quoting “The diagnosis of pellagra is straightforward when the classic rash is present but may be elusive if there are only gastrointestinal and/or neurological manifestations.” And why I believe in many cases Pellagra goes undiagnosed today.  Because doctor's have forgotten how it presents. A longer researcher article about the neurological presentations of pellagra mention the many ways a Niacin deficiency can present itself. Here is the link https://www.hindawi.com/journals/cggr/2012/302875/ and I will quote some of the neurological/dementia related symptom's of an undiagnosed pellagra patient. "Mental symptoms were wider than dementia, in that depression, fatigue, psychomotor retardation, mania, obsessions, and a whole range of psychoses with auditory and visual hallucinations were well described, along with personality change and sociopathic and drug and alcohol addictive behaviours. Panic disorders were seen as was a general inability to deal with physical or mental stress. Poor brain development such as hydrocephalus or cerebral palsy was also common. Acute delirium or even coma occurred, with some patients having myoclonus and other extrapyramidal signs reminiscent of the spongiform encephalopathies. The dementias of pellagra included features akin to Lewy body, Alzheimer’s, frontotemporal, vascular, and prion diseases. Parkinsonism was also common and a festinant gait was first described in pellagrins. Tremors of various descriptions, including asymmetric rest tremors, were noted and some patients had typical paralysis agitans. Pellagrins had a characteristic expressionless facies, so some signs of parkinsonism were present in most cases. Many features of pellagra closely resemble the nonmotor aspects of PD. The neurological manifestation did not stop there because other degenerative conditions, such as an amyotrophic lateral sclerosis-like picture, were described, with fasciculation of the tongue and upper and lower motor neuron signs. Cerebellar syndromes occurred and vertigo was frequent. Headaches, sensory and pain syndromes, epilepsy, and involuntary movements were noted as well as sleep disturbances. Cord lesions were also seen, as was optic atrophy, so there were multiple sclerosis (MS), like variants." It is me again. You can see the neurological symptom's of Pellagra are severe and wide ranging. Taking Niacinamide 3/day for 6 months can alleviate many of these symptom's if your daughter has subclinical pellagra and the doctor's don't know to look for it. I had deep depression for many, many years and I shudder to think now that only a Vitamin could of helped me 30+ years ago and the doctor's didn't know to look for it. Shoot it isn't just Niacin.  All B-Vitamin's help your stress levels.  IF you have stress B-Vitamins can help your stress levels. I take Folic Acid for Blood pressure problems and it keeps my BP with in a normal range. A article on celac.com discussed this topic in detail a few months ago. https://www.celiac.com/articles/24658/1/A-Differential-Diagnosis-How-Pellagra-Can-be-Confused-with-Celiac-Disease/Page1.html I hope it is helpful.  Good luck on your continued journey. If you have never heard of Pellagra you are not alone. Dr. Heaney discusses why this is so in his online article Pellagra and the 4 D's. http://blogs.creighton.edu/heaney/2013/11/18/pellagra-and-the-four-ds/ If you don't have time to read the whole hindawi article I also suggest this shorter but informative blog about why a Niacin deficiency can cause dementia related conditions. https://pellagradisease.wordpress.com/ Then decide for yourself and your daughter's sake to decide whether to take Niacinamide or not to see if it helps the D's symptom's she is experiencing (Digestive, Dementia etc.) The International Journal of Celiac Disease makes note of this in their research that Pellagra could be contributing to symptom's being diagnosed as Celiac disease today instead of a possible (co-morbid) Pellagra that causes the same symptom's. When they discuss how Pellagra and Celiac disease are related (Co-Morbid) in a Celiac diagnosis are surprised to find that in 58% of Celiac's -- can also be diagnosed with Pellagra. See this link http://pubs.sciepub.com/ijcd/3/1/6/ Quoting 3. Pellagra and celiac disease "The two diseases can be connected in two aspects. 58% of pellagra patients were shown to have malabsorption and many had intestinal pathology on biopsies [36, 37]. Alternatively, Pellagra was described in celiac disease [38]. The skin manifestations in pellagra might have some additional etiologies, since multiple nutrient deficiencies are at the origin of the cutaneous manifestations in celiac disease. The following nutritional deficiencies inducing skin rashes, were describe in celiac disease: Zinc, Iron, Vitamin A, E, B12, niacin, folate, selenium and essential fatty acids [39, 40]." If one is being diagnosed incorrectly the other co-morbid conditions can continue to cause Celiac like symptom's. But if the majority of those who have been diagnosed as Celiac could be helped by taking Niacinamide I see no you reason you shouldn't try it. Or at least research it some more. Again good luck on your continued journey. 2 Timothy 2: 7 “Consider what I say; and the Lord give thee understanding in all things” this included. Posterboy by the grace of God,
