My 5 year old daughter had lab work done because of her weight. She has not gained anything in over 2 years and is sitting steady at 32 pounds, she will be 6 in July. Her lab work came back yesterday with the result of possible Celiac Disease and her PCM has referred her to a Gastroenterologist...just waiting for the referral to go through. I am completely clueless about all of this, nothing like this crossed my mind...I actually figured it would be a thyroid issue. I went through her symptoms the last few years and this is what I have...

 

Decreased appetite

Diarrhea (not constant but at least once or twice a week)

Easily bruises

Very poor weight gain

Fatigue

Mouth Sores

 

Since I am so new to any of this, I have tried really hard to look through all the lab results here and try to decipher my daughters. I have spent the whole afternoon reading this site. 

 

Here are the labs

 

IgA 143 (Normal) Limits 33-185 mg/dL

Endomysial Screen (Negative)

tTG Ab, IgA 2.0 Range <20 Negative, 20-25 Equivocal, >25 Positive

 

Gliadin Peptide Ab, IgG 22.6 (Abnormal) Range <20 Negative, 20-25 Equivocal, >25 Positive

Gliadin Peptide Ab, IgA 4.1 (Normal) Range <20 Negative, 20-25 Equivocal, >25 Positive

 

tTG Ab, IgG 17.4 (Normal) Range <20 Negative, 20-25 Equivocal, >25 Positive

 

Thanks in advance to anyone who can offer me some input!

Welcome to the board, decemberhill,  :) and I am sorry it looks like your post has been missed and overlooked :(   Let me attempt to rectify.

 

Your daughter's blood test results show that she makes normal quantity of IgA antibodies, and therefore the IgA testing should be valid for her.

 

The most specific test, endomysial antibodies (EMA) is not positive and her tTG Ab IgA is also negative, as is her Gliadin Peptide Ab IgA (DGP IgA).  However, her Gliadin Peptide Ab IgG (also known as DGP IgG)  is positive.  IgA and IgG are both autoimmune antibodies.  The IgA is usually used and considered to be the celiac antibody; but if an individual does not make normal total quantities of IgA they use the IgG tests.

 

There has recently been some discussion on the board about the meaning of IgG positives on the DGP, and what it means if the person being tested is a normal IgA producer.  Nobody so far has been able to state that it means anything other than celiac disease.  This is probably the reason for the GI referral, so that he can do an endoscopy with biopsy to check for celiac damage in the small intestine.  Do not let him say it is not necessary.  Insist on having it done, and that he take at least 6 samples, because the DGP is the most sensitive of the tests and tends to catch early celiac disease, before there is too much damage.  And if there is not too much damage the naked eye is unable to see it and we have to rely on the biopsy samples and the microscope :)

Decemberhill,

 

The only test I came back positive on was the DGP igG.  I am currently waiting for my biopsy results to come back in a few weeks.  I see that your daughter bruises easily, as I do too.  I thought it was something to do with my iron, but it turned out my iron and ferritin levels were fine.  I'm deficient in Vitamin K, which also causes bruising  :wacko:

 

here are two links to threads I have started:

hope these give you some other ideas!

Thank you so much for your responses. The other diagnosis they are throwing around is Cystic Fibrosis and we go in to talk about that on Thursday. I would much rather it be a Gluten issue. 

 

From my reading and I hope I am correct...the test she was positive with, the DGP IgG shows that there is tissue damage relating to gluten? Also, on two of the tests testing IgA are low...does that mean anything or is that a good thing? Our referral for GI has been approved, although the Dr she was referred to does not treat children so I had to find her a pediatric GI which I think works much better. The Ped Dr has a special interest in Celiac. 

 

PowerOfPositive...please let me know how your biopsies turn out. Looking at so many labs and trying to decipher, I remember seeing your post about only being positive with the DGP IgG. I have started a food diary for my daughter as well as documenting her poo everyday. Is there anything else I should document or note? The GI said that new patient appts are already booked into June...so I think it's going to be a long time before we can get in...unless we get lucky and get a cancellation! 

 

Again, thank y'all so much. This board has been really helpful!

Normally, the IgA testing is considered to be best for those who are IgA sufficient.  The DGP is a newer test than the tTG, is more specific for celiac disease, and tends to pick it up earlier than the tTG.    The low IgA results just show that those tests were negative.  So long as she makes sufficient overall IgA, the low scores on IgA testing have no special significance.  You do not have to be positive on all tests to be celiac - why having the entire panel is recommended.

I will let you know how my biopsies turn out!  I definitely think keeping a food and poop diary would be great.  I even talked about my bowel movements to the GI with the bristol stool chart in mind.  Check it out if you haven't!  I would also suggest keeping track of water.  During my first GI appointment when I said I was frequently bloated and constipated, he asked the obligatory questions of how much fiber and water are in my diet.  I was able to tell him I usually drink between 60-80 oz. of pure water a day in addition to the fruits and veggies I eat.  Documenting any rashes of anything with pictures would also be very helpful.  According to Dr. Rodney Ford, DGP is suggestive of gluten gut damage http://drrodneyford.com/faq/bloods-tests/gluten-blood-tests.html  I am iga sufficient, but my IGA scores were both low.  I'm a 27 y/o female, but since your daughter is 5, Dr. Ford says that ttG is not as reliable in children.  

 

When the GI was going over reasons for Vitamin K deficiency, he mentioned cystic fibrosis, but people tend to be diagnosed as children so that was not applicable to me.  Are you able to get vitamin and mineral testing for children?  can anyone please help me out with this question?  Based on what you said, I would definitely make sure she is tested for Vitamin K.  If you can get your GP to do this, that will give you more information for your GI appointment.   I asked my OB/GYN if she would be willing to order vitamin/mineral testing for me, which thankfully she did without a problem.  When I had my second appointment with the GI, I said my OB/GYN sent you results from some more testing.  He said that Vitamin D deficiency was common, but I peaked his interest when I said I was Vitamin K deficient.  He said he normally doesn't see patients with that deficiency, and according to University of Maryland, a GI doctor is the type of doctor I would expect to see this deficiency since a lot causes seem to be malabsorption issues.  http://www.umm.edu/altmed/articles/vitamin-k-000343.htm  I haven't used antibiotics since last April, I don't have a blocked bile duct, no serious burns, so it seems that it's due to some kind of malabsorption for me.  I will be taking 5 mg of Vitamin K a day and 2000 iu of Vitamin D as directed by my OB/GYN and GI.  

 

I would suggest calling the GI to see if you can get in on a cancellation.  Repeated phone calls are not a bad thing  :)   I hope she starts feeling better soon!!

It's entirely possible to be diagnosed with Cystic Fibrosis and Celiacs. I myself have both, I was diagnosed with CF at 6 months old but struggled until I was 26 with a lot of numerous health issues. I think having CF made my docs write off the possibility of Celiacs also being an issue but the vitamin deficiencies are the same and a lot of the symptoms are the same. Many people have been diagnosed as adults with CF, the oldest person ever diagnosed was in her sixties and her only symptoms up until then were chronic sinus infections and a few bouts of pnuemonia. Get tested for both.

An osteopathic functional medicine doctor I had my 9 year old son too was offering nutrient absorption tests for him.  Yes, children may get them.  Some chiropractors can order them.  In the end my son didn't have them.  I had nutrient tests and they were very helpful for me.

While we are still in the testing mode for my 2yr old...just wanted to confirm that nutrient testing is also done at the young age.

She's had a baseline and a followup already since she was 18months old.

 

(granted no closer to a dx, but we are watching nutrient levels)

Not sure what exactly you mean? A doctor can test blood to see if the iron, vit D, B12, etc is at a good level or not. I would be careful about some of these " tests" by "doctors" that are not MDs. Many have no real science behind them and are designed to extract your money as insurance won't cover them.

Sorry, my post was in response to the question here:

When the GI was going over reasons for Vitamin K deficiency, he mentioned cystic fibrosis, but people tend to be diagnosed as children so that was not applicable to me.  Are you able to get vitamin and mineral testing for children?  can anyone please help me out with this question?  Based on what you said, I would definitely make sure she is tested for Vitamin K.  If you can get your GP to do this, that will give you more information for your GI appointment. 

Yes, any MD is able to the testing, as we are seeing only MDs for my daughter's dx quest.

 

I'm sorry if I confused anyone if I misread the question.

Great! Lots of stuff posted in between! :)

I see no reason her pediatrician couldn't test her blood for vitamins, etc.

I found this but it seems a bit extreme if you haven't had blood levels done first. Maybe something down the road if things don't improve?

    • Before ordering the endoscopy, you would think they would order the complete celiac panel.  Not all celiacs (like me) ever get a positive TTG (I do test positive to the DGP, but negative to the EMA and TTG).  You would think that the additional blood tests would be way more cost effective than going directly to endoscopy.  The endoscopy usually is still considered necessary for a celiac diagnosis, but there does not seem to be strong evidence that she has celiac disease other than a family history.   Some celiacs are seronegative negative, but your daughter was only negative on just one of the celiac tests.  So, she MIGHT be seronegative.  More investigation is needed.  She is NOT IgA deficient, at least for celiac testing (for celiac disease this test is just a control test).   The DGP test seems to be better for small children.   I do not have the complete health history of your child, but I would seek a second opinion before going to an endoscopy at this time with only one test result.  Try to find a celiac-savvy GI -- one who follows what the American GI Association  recommendations for celiac disease and what the Mayo Clinic or a large celiac research center recommends for testing protocol. https://www.mayomedicallaboratories.com/it-mmfiles/Celiac_Disease_Diagnostic_Testing_Algorithm.pdf https://gi.org/guideline/diagnosis-and-management-of-celiac-disease/  
    •   Hello linzk8! I would suggest you to go with natural foods as you are allergic to latex. One of my friends had the same problem. She also had latex allergic. She used Indian nuts to lose weight purchased from the official site of Nuez Dela India and achieved a success. You can also check the same. Eating at the right time is also important. Avoid eating very late at night. It's fine to eat in between meals, but limit your proportions. Never starve yourself! Hope this could help you!
    • My family visited Peru (my 13 year old has celiac) last Christmas, and we found Peru rather gluten free friendly. Peru is the land of corn and potatoes, and they have lots of grill meats.   Their cooking ingredients tend to be naturally gluten-free.   We did the 4 day Inca trail hike to Machu Picchu, and our chef did a great job making gluten-free meals for my daughter.  
    • Most physicians follow the joint commission’s guidelines on prescribing HTN medications which usually begin with a diuretic and calcium channel blocker (the amlodipine) - see below. Is it possible that your bp was still not controlled on the CCB (amlodipine)? So the ARB was added? Again, I’d just like to say that just bc a drug does have certain adverse effects does not mean you will have them, but I understand if you would not even want to take the chance, given a previous history of celiac disease. http://www.aafp.org/afp/2014/1001/p503.html “In the general nonblack population, including those with diabetes, initial anti-hypertensive treatment should include a thiazide diuretic, calcium channel blocker, angiotensin-converting enzyme (ACE) inhibitor, or angiotensin receptor blocker (ARB). In the general black population, including those with diabetes, initial treatment should include a thiazide diuretic or calcium channel blocker. If the target blood pressure is not reached within one month after initiating therapy, the dosage of the initial medication should be increased or a second medication should be added (thiazide diuretic, calcium channel blocker, ACE inhibitor, or ARB; do not combine an ACE inhibitor with an ARB). Blood pressure should be monitored and the treatment regimen adjusted until the target blood pressure is reached. A third drug should be added if necessary; however, if the target blood pressure cannot be achieved using only the drug classes listed above, antihypertensive drugs from other classes can be used (e.g., beta blockers, aldosterone antagonists). Referral to a physician with expertise in treating hypertension may be necessary for patients who do not reach the target blood pressure using these strategies.” Drugs for BP in different classes work by different mechanisms. It may be worth it to print out those huge, long drug information sheets and go over them with a fine toothed comb. As for CoQ10, have you checked for coupons online? Can your doctor write you an Rx and get your insurance to pay? They might say it’s on OTC and you have to pay out of pocket, but it may be worth it to find a way around that - would a prior authorization do the trick? I don’t know, just bringing up the questions. In the report you cited, these concluding words were to me, chilling:
      “Therefore, we suggest the possibility of a class effect.” Losartan, olmeseartan - doesn’t matter. And I'll say it again, there must be a way to disseminate this information more widely as I had no idea about this adverse effect, and never heard any docs speaking about it either. It really warrants wider sharing. Finally, one person who is often an overlooked resource is your pharmacist. They have just tons of knowledge and should be able to talk to you in some depth if asked, in an articulate, easy to understand way. They may even be able to do some digging and research for you. Plumbago
    • Plumbago et al, Thanks for letting me know  about the "artan" drugs being ARBs. I think Cyclinglady was right the Losartan research is not free and thus not public. I saw the link with no abstract but wanted to read it to confirm as you noted in your ETA that it was another "Artan" drug Losartan causing the problem. I believe it is. I found a great (after more digging) review of all the "artans"/ARBs or most of them about whether they can contribute to sprue symptom's in addition to Benicar. here on wiley as studied by the alimentary pharmacology and therapeutic journal (AP&T) for short. http://onlinelibrary.wiley.com/doi/10.1111/apt.14176/full I wish I knew how to post the able alone it is very informative.  Please scroll over the table to the end of it since it even tells how long to expect before your sprue symptom's/conditions improve IF the "artan" drug is causing your symptom's which I find the most helpful thing about the table.  They also note histological feature (degree of villi blunting) to expect on biopsy. They note Losartan can cause "total atrophy of duodenal villi" by their reporting. I also recently had an issue with my potassium levels so I feel sure it is the Losartan. I remember reading a study about how losartan was better at the "chronic cough" I had developed using Lisinopril so I changed to Losartan a few years ago . . . now I find I could of been making my GI symptom's worse. But to answer  your other question since I began taking Folic Acid a few months ago my BP numbers went down to a healthy level of 120/80 or less sometimes . . . but with medicine. I had already been thinking I wanted to try get off the BP medicine (for good) so this is more motivation. C0q10 worked well but it is too expensive for me to take all the time! I called my doctor to have them put me back on Amlodipine/Norvasc and I can't remember why I changed off that medicine to begin with now.  I do remember needing two medicine's back then to control my BP so maybe we stopped the Norvasc instead of the Linsinopril. But now that they have put me back on Norvasc I hope my potassium levels will correct themselves. I just don't feel safe anymore taking Losartan after learning it could be making my GI symptom's worse or causing the to be unreliable. I first thought my touch of D. was from an antibiotic round but when kefir didn't get me back on track I suspected something else when my Vitamin D levels showed up low too again! Thanks everybody for ya'lls great suggestions and good research on my behalf. I also recommend this verywell article if you are still having GI problems and you suspect an "artan" like ARBs BP medicine and looking for a medicine that might have less severe  or more manageable symptom's for your lifestyle because it comprehensively list's the medicine's by drug types. https://www.verywell.com/hypertension-drugs-1745989 no medicine is without a side effect as (I) am learning but I never thought sprue would be one for my BP medicine and why I prefer Vitamins when I can find out which one too take. Now that I have the Norvasc approved as a replacement for the Losartan I might see if my BP goes up again if I stop my medicine all together as I was hoping the Folic Acid might help me with it (without medicine) and it explains why I was low in Folic Acid to begin with again. posterboy,
