Can Biopsy Be Wrong?


Wendyp

Recommended Posts

Wendyp Rookie

I posted a couple months ago about whether or not I should have a biopsy. All my bloodwork was fine except the TTG, which was very slightly elevated (almost one digit over the normal range).

Well, I had the biopsy and the GI said I have celiac. He was surprised, since I didn't really have the GI symptoms and my blood work "looked good". I really wasn't surprised because in the time between the bloodwork and the biopsy (about 3 months---I was supposed to have major surgery during that window, which is the reason for the wait) I started having periods of time where no matter what I ate it made my upper abdomen uncomfortable (maybe reflux?). And also, even though my thryoid was finally diagnosed as low, and I wasn't sleepy anymore due to thryoid meds, I still had days were my body was weak and tired.

However, in the back of my mind I still wonder if the celiac diagnosis was right. The above mentioned symptoms could certainly be something else. The GI doc said the pathologist was "pretty certain". I haven't had a chance to ask him what the "pretty" part means.

I've heard of false negative biopsies, but can there be false positives? My father suggests that before I go all out and change my diet so drastically, I should seek another opinion (he doesn't have much faith in doctors anyway). What do you folks think?

Also, since going gluten free a week ago, I'm sleepy and tired again. Around Christmas I was ready to call my primary care doc and tell her great I was doing on the Synthroid, how it had give me my life back. And now I'm pooped again (thyroid was checked Dec 27th and it looks great). Would going gluten free cause this tiredness?

So let me get this straight... your blood work was only slightly elevated, but your biopsy was positive and the Dr. dx'ed you with Celiac and you are DOUBTING this? Just wanted to make sure I was understanding before I say something that might offend...

Yes there can be false NEGATIVES with the biopsy, but NEVER a false positive. The medical community is extremely reluctant to dx someone with Celiac if they don't have a clear cut indication that they have it. So YES you do have Celiac, start your diet immediately, make sure you are 100% gluten free and don't look back. You do not need a second opinion. If the biopsy was positive, you have it, no way around it.

re: the tiredness, your body is going through an adjustment period. the tiredness is common, you will want to make sure all of your personal care products including makeup and shampoo and conditioner etc... are all gluten free. Some people notice a period of gluten withdrawal, keep plugging away...

You're chance of it being a false positive are incredibly low. They look for blunted villi, and though there are papers published that show a handful of cases (in the world) where dairy has caused villi blunting with a similar pattern, it's is virtually ALWAYS cased by gluten. The fact that your immunochemistry ALSO shows that your body is reacting to gluten pretty much seals the deal.

Please be patient on the gluten-free diet. You need to give your body time to heal, and give yourself time to adjust to the diet. Were you eating enough? Had you eliminated *every* source of gluten? Had you eliminated risks of cross-contamination? Are you sure you weren't just fighting a virus? Were there other stressors in your life that could have been making you tired? Etc, etc.

One of the questions I specifically asked my doctor was about the biopsy results and he told me the biopsy was 100%; no question. Now I guess in theory the results could get accidental swapped with somebody else who had a biopsy, but beyond that it sounds solid.

Sorry, I hit the wrong button above.

I just talked to my GI and he read the pathologist report to me, which said a bunch of stuff I didn't understand but the stuff I understood said that there was blunting of the villa, and the damage was patchy. The doc said that in years past, my biopsy wouldn't have resulted in a celiac diagnosis, but now they're finding out much more about the disease, etc. etc., which, I'm sure you all know. He did say that it is difficult to definatively diagnose until a gluten-free period has been observed. If the person's symptoms have disappeared, then that seals the diagnosis. If not then a second biopsy is warranted.

He really couldn't explain the tiredness...maybe the weather. Maybe I do have a touch of virus. Lots of nasal/sinus stuff right now due to things in the air and maybe all the smoke from wildfires here in Texas.

Thanks for your advice.

The tiredness could be due to a lot of factors. What is the protein level in your diet. A diet higher in protein than a regular diet is recommended to those with celiac. Have you been able to get a nutritionist to help you with your diet? Have you been through everything to eliminate gluten? Not just wheat, but barley, rye, malt, spelt, triticale, oats... When the gluten is completely out of your system, you will notice a difference, promise. Have you eliminated dairy? At the beginning most celiacs have to eliminate dairy until the villi heal. Then it can be tried again in two to three months, depending on healing rates.

Wendy--First, I have to say that I agree with the others who said that you have Celiac and that a positive biopsy is proof of that. During the first 3 months that I was gluten-free, I was tired, hungry and thirsty all the time. I felt I couldn't get enough sleep. I took that as evidence that I was healing and just went with it. Your positive biopsy means that you have damage--even if you didn't have severe symptoms before. My advice, like everyone, is to make sure that you are 100% gluten-free. Go easy on yourself. It takes time. I began to feel better during the 4th. month. I believe that was a combination of time and working out the diet and getting to a point where I was really gluten-free. If you need tips on how to eliminate gluten from your life, there are tons of ideas here you can look up. We can help with any questions you have on that :)

Synthroid is often not helpful. You should try Cytomel or Armour Thyroid. Check out Dr. John Lowe's web site. Just type in John Lowe.

You could be tired because of withdrawal. You have only been off a week. I had lots of aches and pains at first.

      Here is more info about how to do a gluten challenge for a celiac disease blood panel, or for an endoscopy: and this recent study recommends 4-6 slices of wheat bread per day:

      Yes, you are right. Indeed, I’ve been feeling anemic since the beginning of this week, and today I felt horrible during a lecture at the university, I was trembling a lot and felt all my body incredibly heavy, so I had to come back home. I’ll do a blood test tomorrow, but I’m just worried about the possibility of it coming back negative. I’ve been eating two cookies in the morning as my only source of gluten over the past two weeks—could that affect the final result?

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.
