Thanks - I don't ever remember having an actual biopsy to confirm the psoriasis diagnosis that I have received from several dermotogloists over the years, but my psoriasis has typically responded favorably to topical steriods and to a biologic TNF inhbitor (Enbrel/Humira family of drugs). If my skin issue was really DH instead, would it have improved with the TNF inhibitor and topical steriods? I think I read somewhere that DH only responds to Dapsone? I'll take a look at the DH forum and see what I find there.
In light of the weak positive gliadin test I just had, I will ask my dermotologist to take a very close look at everything on my skin and see whether any of it looks like it might be DH....and get biopsies accordingly.
I have a bunch of things going on with my skin - very dry skin in general, plaque psoriasis, guttate psoriasis, pustular psoriasis and lots of tiny red bumps (no fluid) that sometimes turn into guttate psoriasis or disappear. I also probably have some ezcema too....
My skin is definitely taking the brunt of whatever is happening inside my body, and I am on a journey to figure this out and get all of this corrected... My celiac panel results may have uncovered a new clue and a new path for me to go down.....
I am new at this and I want to make sure I understand nora_n's comment -
Are you saying that the Deamidated Gliadin Abs IGA test is the new specific test for Celiac, and the results of that test should hold more weight than the other blood tests? So, I should ignore the negative result on the t-Transglutiminase IgA test, and I should consider the weak positive result on the Deamidated Gliadin Abs IGA as my Celiac blood test result?
If so, then I did score a weak positive for Celiac via a blood test...I really don't want to get a biopsy - I would rather just try a gluten free diet for a minimum of 3 months to see if it clears/improves my psoriasis.
Deamidated Gliadin Abs, IGA -> result says 20 and is flagged as High
Reference interval for this test is:
Weak Positive 20-30
Moderate to Strong Postive >30
t-Transglutaminase (tTG) IgA -> result says <2 U/ml
Reference Interval for this test is:
Weak Positive 4-10
Immunoglobulin A, Qn Serum -> result says 305 mg/dL
Refernce Interval for this test is 70-400
So - the Deamidated Gliadin IgA is Weak Positive, the tTG IgA is Negative, and the Immunoglobulin A Qn Serum is within normal range...
Do these results mean that I have a gluten sensitivity, and that I might benefit from excluding gluten from my diet? Or do I need any additional testing to confirm whether I have a gluten sensitivity? I don't have any digestive issues (that I am aware of), but I've had psoriasis and skin dermatitis for 30+ years, and I am trying to determine if a gluten sensitivity may be the cause of my psoriasis (or if it makes the psoriasis worse)...
Hi - Thanks Bartfull - nice to meet you and everyone on this site,
I have had psoriasis for the last 35 years. I am hoping to find out whether any foods trigger my psoriasis...
I just started working with an allergy doctor who is running a bunch of tests on me - starting with gluten, dairy, eggs, wheat, nightshades (the typical foods that are suspect for psoriatics)...
Bartfull - did you actually get tested for any of the other foods that you found you can't eat? Like corn, tree nuts? Or you just knew from trial and error - eating/eliminating the food from your diet?
Hi, I am in the process of having celiac disease testing done....no results yet. I have not excluded gluten from my diet yet, but I got palmoplantar pustular psoriasis about a year ago. Regarding your statement "My primary symptom of celiac is palmoplantar pustular psoriasis."-->> is palmoplantar pustular psoriasis (PPP) officially recognized as a symptom of celiac disease that can be used to diagnose celiac disease? I had heard about dermatitis herpetiformis specifically being a celiac symptom, but had not heard about PPP.... Or, is your PPP more a symptom that is a side effect of excluding gluten products from the diet? Do you know if there is a reliable test to determine whether someone has a biotin deficiency - I see mixed info about this on the internet.
Anyway - How are you doing with the biotin supplementation? Has this helped your palmoplantar pustular psoriasis? Have you seen any side effects? I am going to discuss with my doctor trying biotin for my palmoplantar pustular psoriasis. Funny thing with me is that I started eating yogurt daily about a year and half ago.... I started getting the palmoplantar pustular psoriasis about a year ago.... wonder if there is a relationship?
