Dh And Iodine Contrast

Has anyone who experiences the DH rash had a CT scan with contrast? My doctor ordered one for me, and when I realized that the contrast is iodine based, I headed straight here to ask around. I was not properly diagnosed with DH rash after my celiac diagnosis, but my doctor strongly suspected that's the kind of rash I had, since it occurred around the time of my celiac disease diagnosis and cleared since adopting the gluten-free diet. I had a small bit of rash breakout after eating some seaweed snacks. I read that those with DH rash often need to avoid iodine, so I have since then.

 

Has anyone with DH had this type of procedure done? An imaging tech at the center where I'm having my scan said that there's a pre-medicating protocol for those with allergies to iodine. I don't understand the DH rash/iodine connection, so does anyone know if premedicating would be effective? Anyone with experience with this out there?

 

Thanks!

Do have a talk with your doctor about this concern. You'll need to know what the premedicating is and whether it is for allergies to iodine or whether it is a different form of contrast without iodine. Celiac isn't an allergy so don't know if that protocol would help. Years ago my doctor scheduled my CT specifically without the iodine because of my DH but I don't know if the iodine is a serious concern or not.  They may have developed new contrast materials that are iodine free since then.

      Celiac and allergic to common subs and adds in prepared foods

      By DAR girl · Posted

      Looking for help sourcing gluten-free products that do not contain potato or corn derived ingredients. I have other autoimmune conditions (Psoriatic Arthritis and Sjogrens) so I’m looking for prepared foods as I have fatigue and cannot devote a lot of time to baking my own treats.

      Disregarded

      By Scott Adams · Posted

      I am so sorry you're going through this. It's completely understandable to feel frustrated, stressed, and disregarded after such a long and difficult health journey. It's exhausting to constantly advocate for yourself, especially when you're dealing with so many symptoms and positive diagnoses like SIBO, while still feeling unwell. The fact that you have been diligently following the diet without relief is a clear sign that something else is going on, and your doctors should be investigating other causes or complications, not dismissing your very real suffering.

      Paying for my own Celiac screening at WalkInLab so a positive result doesn’t become part of my medical history

      By Oldturdle · Posted

      It is just so sad that health care in the United States has come to this.  Health insurance should be available to everyone, not just the healthy or the rich.  My heart goes out to you.  I would not hesitate to have the test and pay for it myself.  My big concern would be how you could keep the results truly private.  I am sure that ultimately, you could not.  A.I. is getting more and more pervasive, and all data is available somewhere.  I don't know if you could give a fake name, or pay for your test with cash.  I certainly would not disclose any positive results on a private insurance application.  As I understand it, for an official diagnosis, an MD needs to review your labs and make the call.  If you end up in the ER, or some other situation, just request a gluten free diet, and say it is because you feel better when you don't eat gluten.      Hang in there, though.  Medicare is not that far away for you, and it will remove a lot of stress from your health care concerns.  You will even be able to "come out of the closet" about being Celiac!

      Yes, I've posted a few times about two companies: Request a Test and Ulta Labs. Also, pretty much we can all request any test we want (with the possible exception of the N protein Covid test and I'm sure a couple of others) with Lab Corp (or Pixel by Lab Corp) and Quest. I much prefer Lab Corp for their professionalism, ease of service and having it together administratively, at least in DC. And just so you know, Request a Test uses Lab Corp and Quest anyway, while Ulta Labs uses only Quest. Ulta Labs is cheaper than Request a Test, but I am tired of dealing with Quest, so I don't use them so much.

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      PS - I think you meant this site, but I don't believe it has been updated in years: http://glutenfreedrugs.com/ so it is best to use: You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/
