Positive bloodwork, negative biopsy

Hello! I’m hoping for some insight on this. My husband was experiencing horrible GI symptoms after everything he ate for a few years. He went to a gastroenterologist and had a bunch of bloodwork and it came back positive for Celiac. They ordered an endoscopy and biopsies and those came back negative. The specialist basically said you’re fine and feel free to eat gluten. My husband cut out all gluten after the endoscopy and his symptoms completely stopped immediately (and haven’t returned for 2 months with gluten-free diet). It just doesn’t sit right with us that his bloodwork was positive and they are completely dismissing that because the biopsy was negative. Where do we go from here? A functional/naturopath? What a frustrating process! Any insight would be appreciated!

Unfortunately test results for celiac disease are not always definitive, and many errors can be made when doing an endoscopy for celiac disease, and they can happen in many ways, for example not collecting the samples in the right areas, not collecting enough samples, or not interpreting the results properly and giving a Marsh score. 

Many biopsy results can also be borderline, where there may be certain damage that could be associated with celiac disease, but it just doesn't quite reach the level necessary to make a formal diagnosis.

The same is true for blood test results. Over the last 10 years or so a new "Weak Positive" range has been created by many labs for antibody results, which can simply lead to confusion (some doctors apparently believe that this means the patient can decide if they want more testing or to go gluten-free). There is no "Weak Negative" category, for example. Many patients are not told to eat gluten daily, lots of it, for the 6-8 week period leading up to their blood test, nor asked whether or not they've been eating gluten. Some patients even report to their doctors that they've been gluten-free for weeks or months before their blood tests, yet their doctors incorrectly say nothing to them about how this can affect their test, and create false negative results.

Unfortunately many people will continue to suffer needlessly and eat gluten due to these errors in performing or interpreting celiac disease tests, but luckily some will find out about non-celiac gluten sensitivity on their own and go gluten-free and recover from their symptoms. Consider yourself lucky if you've figured out that gluten is the source of your health issues, and you've gone gluten-free, because many people will never figure this out.

Sarah Marie, can you specify exactly which blood tests were positive? Some of the tests are less specific for celiac disease per se but could indicate a type of reaction to gluten that doesn't cause damage to the lining of the small bowel. This is termed NCGS (Non Celiac Gluten Sensitivity).

That wouldn't sit right with me either. I'm wondering if you can get a second opinion? Meaning - I guess - you'd need to call the doctor's office very quickly to tell them not to dispose of the specimens (they would have to call the pathologist, I'd guess) and to have them read by another pathologist. I'm just tossing that out as a possible idea, I don't really know if it would fly or not. But we do add-on blood tests after the blood's been collected all the time, so it may be worth it to ask if the specimens have still been preserved. Otherwise, in addition to what Scott said, it's possible that the biopsies were indeed negative which may just mean no damage yet. That's good. But that does not mean he doesn't have celiac disease. To be told that is kind of careless, if you ask me.

Actually, Sarah Marie, I think you have your answer for all practical purposes. The bloodwork is positive and symptoms disappear upon cessation of gluten consumption. Is there a particular reason you need an official diagnosis?

The main factor we’d like a conclusive diagnosis for is to know how strict we need to be for cross contamination. It’s one thing to be gluten free but it’s a whole other level of carefulness if celiac. We also have 3 kids in the house who still eat gluten.  I appreciate your insight with all of this! Thank you!

With your strong family history of celiac disease, you need to get your kids regularly tested. Two recent large studies, one done by the Mayo Clinic involving well over 300 people, pegged the incidence of celiac disease in first degree relatives of those with celiac disease at over 40%. This was proven by biopsy. Many or most of them were of the "silent" type. That is to say, they were largely asymptomatic and so to be diagnosed with celiac disease caught a lot of them quite by surprise. To be fair, this conflicts with older studies that put the figure at more like 10%. But I think you would be foolish not have a gluten free household. The chances are quite good that your children already have or will develop celiac disease. It typically takes 10 years or more for people to get a celiac diagnosis from the onset of symptoms because most of the time the symptoms are attributed to something else. Or, the symptoms were so subtle that by the time they became serious enough to warrant investigation, villous atrophy is quite advanced and attendant health issues are well underway. Would you want this to happen to your kids? And do you want to risk your own health through repeated cross contamination because several others in the household are still consuming wheat. And they are kids. How careful are they going to be? I hope this doesn't offend you but I sense you are a little in denial.

This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. You have 3 positive tests here, which make it extremely likely that you have celiac disease, especially with the family history, symptoms, etc. I think you ought to be very strict with your gluten-free diet going forward.

      Test result insight

      By disneyfamilyfive · Posted

      Good morning, I thought I’d quickly update this post.  A week or so after my test results were posted, my doctor’s nurse called to say 2 of 3 blood tests showed elevated numbers and referred to GI for further evaluation.  It took about 3 -4 weeks to get into a GI, it was over the holidays too, so I’m sure that pushed things out a bit.  Met with the GI who was great, really listened and said that even though the main celiac test was still in normal range, there are 2 tests that are not and in his experience not all 3 tests need to be positive to take the next steps.  He said after listening to all my symptoms, and looking through my recent medical history he felt that celiac was very likely.  5 days later I was in for an endoscopy (and colonoscopy just to cover all bases at once) and 6 days later the biopsy results came back as positive for celiac sprue.  GI of course said a strict gluten free diet, referred to GI registered Dietitian and come back in one year for a repeat endoscopy to determine healing. If symptoms don’t subside (or improve) after gluten free diet for a couple then return sooner.

      Can food allergies like milk and soy flatten villi?

      By knitty kitty · Posted

      @Matt13  I understand where you're coming from.  Seemed I was reacting to all sorts of foods there for a while, but a low histamine Paleo diet really helps.   We make histamine in our bodies as a useful  neurotransmitter (causing alertness), and also as a response in the immune system.  Histamine is made and released by Mast Cells.  Mast Cells can become hypersensitive to stimulus and release histamine easily, like having an itchy trigger finger.  Mast Cells need Thiamine Vitamin B 1 Benfotiamine in order to NOT release histamine.  Mast Cells that do not have sufficient Thiamine release histamine easily and at the slightest provocation.   Plants and other animals make histamine, too.  By removing high histamine foods from the diet, more histamine can be removed from the body.  We need Pyridoxine, Vitamin B 6, Vitamin C, Cobalamine, B12, and Thiamine B1 to make Diamine Oxidase, an enzyme that breaks down histamine.  If we don't make sufficient DAO ourselves, DAO supplements are available over-the-counter.   Removing Nightshades (tomatoes, potatoes, eggplant and peppers) was very helpful.  Nightshades contain alkaloids that cause Leaky Gut Syndrome wherein large molecules of food can pass through the walls of the intestines into the bloodstream, traveling to other organs and structures where they promote inflammation.   After a few days on the low histamine Paleo diet, the Autoimmune Protocol diet, I started feeling better.  My diet was really restricted, but I felt so much better, I stuck with it.  Eating foods that were easy to digest and low in histamine allowed time for healing.  After a few weeks, I was ready to add one food at a time (two week period) back into my diet.  I had setbacks when I ran into a food my body didn't like, and had to go back to the start, but it was worth doing.  Celiac is a marathon, not a sprint.   Blood tests are not accurate measurements for various B vitamin deficiencies.  Vitamin levels in the bloodstream are different from the amount stored inside cells inside organs where they are utilized.  You can have symptoms of a deficiency yet have "normal" blood levels.  The best way to test for a B vitamin deficiency is to take it and look for health improvement.  B vitamins are easily excreted because they are water soluble.  Malabsorption in Celiac can affect all the vitamins and minerals our bodies need, not just one.  Do talk to your doctor and nutritionist about supplementing while healing.

      DH and swollen lymph nodes

      By Morgan Tiernan · Posted

      A little late to the party in terms of seeing this and responding to it, so apologies! But I wanted to responds as this sounds exactly like my experience. I had covid, followed by shingles, followed by strep… that unlucky bout of infections is what lead me here with dermatitis herpetiformis. I was also self diagnosed in the beginning and turns out I was absolutely right! Currently waiting for biopsy confirmation though. In terms of swollen lymph nodes, I get this when my rash is present. Mostly in my neck and they’re a lot more swollen if I’ve been cross-contaminated with gluten and when the rash is at its worst!

      How to navigate living with dermatitis herpetiformis

      By knitty kitty · Posted

      Welcome, @Morgan Tiernan, The best thing to clear my dermatitis herpetiformis is to take Niacin, Vitamin B 3, the form called nicotine acid, the kind that causes flushing of the skin.  Flushing Niacin clears my skin quickly.   Yes, the flushing might seem really strange, but it opens the tiny capillaries in the surface of the skin which helps remove the antibodies that gather in those pustules.  The flushing lessens the longer Niacin is taken, but still works at keeping the blisters away.   Be sure to take a B Complex and Benfotiamine, a form of Thiamin , Vitamin B 1.  Covid, shingles and other infections like strep throat deplete our Thiamine quickly.  Having frequent infections can indicate low Thiamine.  We have a higher metabolic demand during infections, physical trauma or surgery, emotional and mental stress, and while physically active like dancing.    Thiamine has anti-virus and antibacterial properties.  The eight essential B vitamins work together.  Taking Benfotiamine in addition to the B Complex is safe and nontoxic.  Excess B vitamins are easily excreted because they are water soluble.  New Celiacs are often low in vitamins and minerals due to malabsorption.  Vitamin D can help calm the immune system.  Following a low histamine Paleo diet , like the Autoimmune Protocol Diet by Dr. Sara Ballantyne, a Celiac herself, is also very helpful.  Steroids lower histamine, but the low histamine AIP diet is safer.   This research may be old, but Flushing Niacin does work!!! Nicotinic acid therapy of dermatitis herpetiformis https://pubmed.ncbi.nlm.nih.gov/15412276/ P.S. Wearing natural fibers helps my dermatitis herpetiformis.  Synthetic fibers keep sweat next to the skin, causing further irritation.  Natural fibers wick moisture away, keeping skin dry and exfoliated.
