Hey all!

I have a little boy, now 6yrs, and he has this history: 6weeks of diarhea at 9m of life (dx of rotavirus diarrhea). after that normal life, just with problems in feeding (he didnt like food at all... since 1-2 years0old, I had to insist always, always, for him to eat, every day. rarely he asked for food, or said he was hungry. sometimes complained of stomach ache, and always had a more distended belly. with the age of 5 years, began to lose speed / fall in growth curve for height and growth. With 5y7m, he broke his arm in a silly palying with friends in school, at this time I was scared. And we began to investigate. Idiopatic short stature? > GH deficiency ? inconclusive exs. Hypothyroidism appeared > then comes MY QUESTION:

6yrs > weakly positive TTG + negative EMA + positive biopsy (Marsh type I - just few diminished vili and 35 lynphocytes (normal < 30).

And the weird thing: HLA DQ2 and DQ8 were NEGATIVE!!!

IS IT POSSIBLE?

Please help me...

PS. 2 weeks after GFD --- my child and my husband are on it... Both improved on their gastrointestinal symptoms...

Today, we went to a japanese restaurant, my husband ate (by mistake) a shimeji with a shoyo with gluten...!!! People!!! His diarrhea is back!!!!

I cant believe this is not celiac disease... Just because the HLA are negative... How to explain all this?

It is quite possible to have celiac and not have one of the two most commonly associated genes. If your son and husband are doing well on the diet just keep it up.

Yes, it's possible to have only part of the celaic panel positive and lack the so-called celiac genes. DQ2 and DQ8 only convey risk, they do not guarantee presence or absence of celiac disease. Notice that Ravenwoodglass who answered above is double DQ9 and had very severe celiac symptoms.

I hope your son improves on the gluten free diet! :)

skylark and ravenwoodglass,

thanks for your answers... im really worried, because all cientific information that i read and study about those HLA genes says "if HLA tests are negative, celiac disease is almost excluded..."...

and i wrote to an expertise physician / chief of a celiac center in US, and he wrote: "probable your son is not celiac".

but at the same way, i think: if HLA genes are present in 98% of celiac disease patients, there are 2% of then without it... so, i do believe, with all this improvement we are seeing in our lovely 6yo son, that my son must have this, or at least some intolerance, something i dont know how to describe...

we are going to wait some more weeks, and we are monitoring his weight and height monthly, to see if there will be some response in the extra-gastrointestinal symptoms (hypothiroidism / growth chart - percentil curves).

Thanks, my friends.

I loved this forum.

One other thing to keep in mind as far as the genes go is that not all diagnosed celiacs are gene tested. I think that the number of folks diagnosed without the commonly associated genes would be a higher percentage if they did.

I do wish more doctors knew that the gene test is not the be all and end all of diagnosis.

Your plan to keep him gluten free and monitor his progress is a good one. Since he had a positive biopsy do keep him strictly gluten free.

No, the studies have been done. Prometheus did a very large genetic study of 10,000 people with GI trouble. 0.16% of the people who were celiac by blood test didn't have DQ2 or DQ8. This means celiacs without the usual genes are 1.6 per thousand.

I'm diagnosed celiac from blood work and biopsy. I've never had the genetic tests done. My youngest son is diagnosed by blood work, his response to the gluten free diet/gluten reintroduction and my diagnosis. I wouldn't let the genetic tests keep you from putting your son gluten free and hubby. Three positives is pretty darn diagnostic of celiac despite the negative genes.

Roda, Sky and Raven,

Thanks for your information. This kind of contact is important to give us more confidence to lead with this disease.

I also agree with Roda, in the case of my little son, we have many features, and just one HLA test that is negative.

Its better to wait and see what is going to happen in the future. Our only fear is to loose time doing another thing that will improve his growth, just like, for example, GH, if his case is some type of GH deficiency or resistance, and not celiac disease...

But at least one thing Im sure: without gluten, both my son and my husband are doing very well.

Best regards, Mara

An endocrinologist can tell you if he has a GH deficiency without him having to go back on gluten. If his growth related problems are due to celiac he should catch up.

raven, the history of my son started with the failure to thrive - percentil 2,5 in gowth chart >> then a pediatric endocrinologist, and the blood tests to see GH deficiency were "unconclusive". then this endocrinologist wanted, even with unconclusive tests, to start growth hormone, but at this time the TGG AB appeared, and then the hypothiroidism, and then the GI biopsy (mild positive - MARSH I abnormalities), and then the negative HLA...

so my son has an unconclusive GH stinuli test, and this history of celiac disease a little bit "confused" (neg EMA / mild positive TGG / mild positive biopsy / negative HLA / good GI symptoms response to GFD.

What we're waiting: some response >>> to catch up the normal growth.

If I read you correctly, you are only two weeks into GFD. It will take a little while before you will notice a growth spurt, but not too long at age 8, I would think. Hang in there!

      I do not know this, but since they are labelled gluten-free, and are not really a product that could easily be contaminated when making them (there would be not flour in the air of such a facility, for example), I don't really see contamination as something to be concerned about for this type of product.

      @Jane02, I hear you about the kale and collard greens.  I don't do dairy and must eat green leafies, too, to get sufficient calcium.  I must be very careful because some calcium supplements are made from ground up crustacean shells.  When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.  This is safe and nontoxic.  Vitamin D level should be above 70 nmol/L.  Lifeguards and indigenous Pacific Islanders typically have levels between 80-100 nmol/L.   Levels lower than this are based on amount needed to prevent disease like rickets and osteomalacia. We need more thiamine when we're physically ill, emotionally and mentally stressed, and if we exercise like an athlete or laborer.  We need more thiamine if we eat a diet high in simple carbohydrates.  For every 500 kcal of carbohydrates, we need 500-1000 mg more of thiamine to process the carbs into energy.  If there's insufficient thiamine the carbs get stored as fat.  Again, recommended levels set for thiamine are based on minimum amounts needed to prevent disease.  This is often not adequate for optimum health, nor sufficient for people with absorption problems such as Celiac disease.  Gluten free processed foods are not enriched with vitamins like their gluten containing counterparts.  Adding a B Complex and additional thiamine improves health for Celiacs.  Thiamine is safe and nontoxic even in high doses.  Thiamine helps the mitochondria in cells to function.  Thiamine interacts with each of the other B vitamins.  They are all water soluble and easily excreted if not needed. Interesting Reading: Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/ Safety and effectiveness of vitamin D mega-dose: A systematic review https://pubmed.ncbi.nlm.nih.gov/34857184/ High dose dietary vitamin D allocates surplus calories to muscle and growth instead of fat via modulation of myostatin and leptin signaling https://pubmed.ncbi.nlm.nih.gov/38766160/ Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial https://pubmed.ncbi.nlm.nih.gov/31746327/ Vitamins and Celiac Disease: Beyond Vitamin D https://pmc.ncbi.nlm.nih.gov/articles/PMC11857425/ Investigating the therapeutic potential of tryptophan and vitamin A in modulating immune responses in celiac disease: an experimental study https://pubmed.ncbi.nlm.nih.gov/40178602/ Investigating the Impact of Vitamin A and Amino Acids on Immune Responses in Celiac Disease Patients https://pmc.ncbi.nlm.nih.gov/articles/PMC10814138/

      Thank you so much @knitty kitty for this insightful information! I would have never considered fractionated coconut oil to be a potential source of GI upset. I will consider all the info you shared. Very interesting about the Thiamine deficiency.  I've tracked daily averages of my intake in a nutrition software. The only nutrient I can't consistently meet from my diet is vitamin D. Calcium is a hit and miss as I rely on vegetables, dark leafy greens as a major source, for my calcium intake. I'm able to meet it when I either eat or juice a bundle of kale or collard greens daily haha. My thiamine intake is roughly 120% of my needs, although I do recognize that I may not be absorbing all of these nutrients consistently with intermittent unintentional exposures to gluten.  My vitamin A intake is roughly 900% (~6400 mcg/d) of my needs as I eat a lot of sweet potato, although since it's plant-derived vitamin A (beta-carotene) apparently it's not likely to cause toxicity.  Thanks again!

      Hello, @Jane02,  I take Naturewise D 3.  It contains olive oil.   Some Vitamin D supplements, like D Drops, are made with fractionated coconut oil which can cause digestive upsets.  Fractionated coconut oil is not the same as coconut oil used for cooking.  Fractionated coconut oil has been treated for longer shelf life, so it won't go bad in the jar, and thus may be irritating to the digestive system. I avoid supplements made with soy because many people with Celiac Disease also react to soy.  Mixed tocopherols, an ingredient in Thornes Vitamin D, may be sourced from soy oil.  Kirkland's has soy on its ingredient list. I avoid things that might contain or be exposed to crustaceans, like Metagenics says on its label.  I have a crustacean/shellfish/fish allergy.  I like Life Extension Bioactive Complete B Complex.  I take additional Thiamine B 1 in the form Benfotiamine which helps the intestines heal, Life Extension MegaBenfotiamine. Thiamine is needed to activate Vitamin D.   Low thiamine can make one feel like they are getting glutened after a meal containing lots of simple carbohydrates like white rice, or processed gluten free foods like cookies and pasta.   It's rare to have a single vitamin deficiency.  The water soluble B Complex vitamins should be supplemented together with additional Thiamine in the form Benfotiamine and Thiamine TTFD (tetrahydrofurfuryl disulfide) to correct subclinical deficiencies that don't show up on blood tests.  These are subclinical deficiencies within organs and tissues.  Blood is a transportation system.  The body will deplete tissues and organs in order to keep a supply of thiamine in the bloodstream going to the brain and heart.   If you're low in Vitamin D, you may well be low in other fat soluble vitamins like Vitamin A and Vitamin K. Have you seen a dietician?
