IVP (kidney) dye and shellfish allergy
Post by booandbrimom on Jan 18th, 2009 at 08:18 am
So...I had a medical test this weekend and mentioned I'm allergic to IVP/kidney dye. The technician said "are you also allergic to shellfish? That's a common thing."
I am not as far as I know...but honestly, I don't like the idea of things that come in shells and probably haven't tried all the shellfish out there. I came home and looked it up and most of the sites seemed to think this was a myth - that the amount of iodine in shellfish is not the same as IVP dye and that shellfish allergy is triggered by a protein, not iodine.
Anyone know for certain? It does give me a good reason to pass on the ever present oysters at Christmas, of course...

When I was 27, I was hospitalized for three days for 'acute gastroenteritis', possible allergic reaction. In addition to intestinal bleeding, I was also covered in giant hives.
As my dinner the night before was shrimp - with two glass of wine, the doctors suggested that it may be have an iodine allergy from the shrimp. Though it was never suggested that I go to an allergist to be tested, I was told to never have any tests that involved IV iodine.
Years later, when I had to have a cat scan, I mentioned this to the doctor - and told him that I eat shrimp all the time with no problems. He still flatly refused to give me iodine for the cat scan. I had an MRI instead. So to this day, my records say, 'iodine allergy'.

I have had a few IVPs done in my lifetime. First one when I was a kid (maybe 7 or 8) then another in high school, and the third time I was in my mid 20's. Well on the third one I had a pretty bad reaction. Itchy hives covering my face, burning skin, and dizzy (probably low BP). I believe I was only treated with benadryl (definately no epi pen) and it resolved.
Now I am definately NOT allergic to shellfish. I eat tons of it!! Not so much lately, due to not cooking it at home any more (kids don't eat it). But I have always loved shrimp, oysters, mussels, crab, and especially lobster.
I've never been officially skin or blood tested for anything, but know for certain what happened after that IVP was an allergic reaction.
So I guess it's something similar, but not identical to, the iodine in shellfish.
Now that I am educated on allergies b/c of my kids - I do try and have a benadryl with me in my purse if I know I'll be eating seafood. You never know if one day I could develop an allergy to it. It won't, however, keep me from eating my beloved occasional lobster tail

Boo---I've posted about this somewhere . . . I'll go find it.
But technically, oysters wouldn't be an issue I don't think. I think the iodine thing is a crustacean occurance.

Also what about the dye that they inject into you when you go for an x-ray or sonogram? I'm actually curious about that because I may need to do that one day soon and am concerned.
Reading up on Kidney Stones  I saw this:
Quote:
You may want to ask your physician about the amount of radiation used during the CT procedure and the risks related to your particular situation. It is a good idea to keep a record of your past history of radiation exposure, such as previous CT scans and other types of x-rays, so that you can inform your physician. Risks associated with radiation exposure may be related to the cumulative number of x-ray examinations and/or treatments over a long period of time.
If you are pregnant or suspect that you may be pregnant, you should notify your physician. Radiation exposure during pregnancy may lead to birth defects.
If contrast dye is used, there is a risk for allergic reaction to the dye. Patients who are allergic to or sensitive to medications, contrast dye, iodine, or shellfish should notify their physician.

Actually, I saw it initially on another site that I can't find. But this one says something similar--just talks about more severe kidney concerns than I think I have.

I posted a question about the dye since I'm allergic to shellfish and react to many things, I had to have a CT scan done but when I talked to my dr about being concerned with my allergies with the dye he told me I can have an MRI with contrast which is different then the dye used for CT Scans. Most people don't react to the contrast for MRI and I did well with that. I had a pelvic and abdominal MRI with and W/O contrast and was fine during and after that.

I'm trying to look up IVP dyes and the brand name READI-CAT. I discovered from a kidney x-ray that I am allergic to IVP dyes - I stopped breathing and almost died. I was told to stay away from shellfish, but an allergist confirmed there was no link. Doctors think it's the iodine, but in my case I can eat shellfish with no issue, but I will die from IVP's. I was supposed to get a CT scan, but since no one could assure me the contrast READI-CAT is not the same dye which can kill me, I have cancelled the appointment. Wondering if anyone knows more about this. I would also encourage people to get properly tested for allergies to know for sure about shellfish. There is a lot of cross contamination in restaurants and it's piece of mind to know you will be safe.

I'm not an expert. I don't think the ingredients are the same shellfish and the dye they use for cat-scans. I know someone who isn't allergic to shellfish and had a mild reaction to the dye.
I do know that lots of people do react to the dyes. I've seen epi-pens in dr's office where they use the dyes. I think one should get tested for shellfish to confirm and if someone has had shellfish with not problems I don't think they need to stop eating it. Maybe it's a good question for an allergist. I hope someone else here can help answer your question.
Wanted to add that since I react to many things I had an MRI done instead of CT-Scan because they use a different type of dye where they don't have any incidents of people reacting to it. I would ask if you can have an MRI done instead because I think all CT-Scans are done with a similar type of dye.

Yes, allergies to IVP are very real.
My mother was allergic to the IVP Iodine Contrast and told the technician at the hospital prior to her CT Scan, but the technician injected her anyway and killed her!
All mom's medical records show her allergy listed, however the hosptial personell told us she never said a word about it and they did not know about her allergy. They ushered us out of the hospital the day that she died.
We have since optained her medcial records and they clearly show she was allergic to the contrast and she told them that day.

I would stay clear of any CT Scan, contrast, IVP, Iodine injections, especially Optiray. Since it does not appear that radiologists or technicians know how to use them properly, especially in knowing what to do in an emergency situation, concerning an allergic reaction. They may not be prepaired to save anyone who may get into trouble!
Check Before They Inject
Avoid IVP CONTRAST INJECTIONS
Avoid OPTIRAY INJECTIONS

Sorry to hear about your mom and thank you for posting your experience. It will help many people in the future.

WELL THEY FINALLY CAME CLEAN.
THE DOCTOR WHO WROTE MOM'S PRESCRIPTION, HAD THE MEDICAL RECORDS THAT SHOWED THE WAS "ALLERGIC TO THE CONTRAST", BUT HE WROTE THE PRESCRIPTION WITH CONTRAST ANYWAY.
THE HOSPTIAL STAFF WHO DENIED THAT THEY HAD ANY KNOWLEDGE OF MOM'S ALLERGIC REACTIONS TO THE CONTRAST IN PREVIOUS EXAMS ADN CLAIMED THA TSHE NEVER TOLD THEM...
WELL THEY LIED, SINCE ALL THE RECORDS FOR THAT DAY CLEARLY SHOW THAT OUR MOTHER DISCLOSED HER ALLERGY TO IVP CONTRAST AND CLEARLY ADVISED THEM OF HER PREVIOUS RESPONSE TO THE USE OF CONTRAST.

In my points..You certainly have legal rights regarding pursing a medical malpractice lawsuit for the first surgeons performance. In terms of medical negligence, it sounds like you have solid legal grounds for which to pursue a legal claim.
Whether or not you will be able to file a suit successfully depends on the severity and value of your damages. You can demand all your lost income, pain and suffering, medical expenses, etc. You should talk to a medical malpractice lawyer to discuss your case and find out what the best option is for your situation.For more detail read this...
