A Look at Giradia-related Elevation of Anti-transglutaminase and Anti-endomysium Antibodies

Can serum anti-tissue transglutaminase (tTG) and anti-endomysium antibodies (EMA) be helpful in differentiating giardiasis from celiac disease?

Celiac.com 05/12/2021 - Some types of intestinal inflammation or autoimmune disease can increase markers for celiac disease. A number of reports have suggested that intestinal infections may cause celiac disease to develop in certain people.

A team of researchers recently set out to determine whether serum anti-tissue transglutaminase (tTG) and anti-endomysium antibodies (EMA) may be helpful in differentiating between giardiasis and celiac disease.

The research team included Kurt Hanevik, Elisabeth Wik, Nina Langeland & Trygve Hausken. They are variously affiliated with the Centre for Cancer Biomarkers CCBIO, Department of Clinical Medicine, and the Department of Clinical Science at the University of Bergen, Bergen, Norway; and the Department of Pathology, the National Centre of Functional Gastrointestinal Disorders, Section of Gastroenterology, Department of Medicine, and the National Advisory Center for Tropical Infectious Diseases, Department of Medicine at Haukeland University in Bergen, Norway.

The team looked at eight cases where patients showed elevated CeD serological markers and pathological duodenal histology during, or shortly after, Giardia infection.

Their recent paper presents follow-up clinical and serological findings to determine which of these eight patients were diagnosed with celiac disease.

Serum levels of tTG and EMA were poor indicators for spotting the difference between patients where celiac disease was excluded, and those who were later diagnosed with celiac disease.

In their paper, the team discusses the value of these serological celiac markers in relation to celiac diagnosis in cases with chronic or recent giardiasis.

About Me

Scott Adams was diagnosed with celiac disease in 1994, and, due to the nearly total lack of information available at that time, was forced to become an expert on the disease in order to recover. In 1995 he launched the site that later became Celiac.com to help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives. He is co-author of the book Cereal Killers, and founder and publisher of the (formerly paper) newsletter Journal of Gluten Sensitivity. In 1998 he founded The Gluten-Free Mall which he sold in 2014. Celiac.com does not sell any products, and is 100% advertiser supported.

Does IgA tTG Predict Mucosal Recovery in Children with Celiac Disease on a Gluten Free Diet?
Celiac.com 01/23/2017 - It makes some kind of sense that kids with celiac disease who follow a gluten-free diet will recover, their guts will normalize, and their levels of IgA tissue transglutaminase antibodies would drop to reflect this change; whereas high antibodies likely mean no recovery, right? But is that true? Is there really a correlation on any level?
To test this idea, a team of researchers recently set out to document the rate of mucosal recovery in kids with celiac disease on a gluten-free diet. They also wanted to figure out whether IgA tissue transglutaminase (tTG) correlates with mucosal damage at the time of a repeat endoscopy with duodenal biopsy.
The research team included Maureen M. Leonard, Dascha C. Weir, Maya DeGroote, Paul D. Mitchell, Prashant Singh, Jocelyn...

Is a One Two Punch of Anti-tTG Tests a Reliable Way to Diagnose Celiac Disease?
Celiac.com 02/01/2018 - To make a clinical diagnosis of celiac disease, doctors use serological testing for IgA antibodies to human tissue transglutaminase (anti-tTG) which indicate celiac disease autoimmunity. However, some tests are more highly sensitive for anti-tTG, while other tests are highly specific. So, is combining two tests a reliable strategy for screening for celiac disease in clinical practice?
A team of researchers recently compared the performance of three kits used to diagnose celiac disease, and evaluated the point prevalence of celiac disease autoimmunity in a South Indian urban population.
The research team included G Venugopal, J Mechenro, G Makharia, A Singh, S Pugazhendhi, R Balamurugan, and BS Ramakrishna. They are variously associated with the SRM Institutes...

Enterovirus Infection in Childhood Could Trigger Celiac Disease
Celiac.com 02/18/2019 - Many researchers have suspected that childhood infections with certain viruses may open the door for the development of celiac disease. Celiac.com has covered the connection in previous articles, such as Can Viruses Trigger Celiac Disease? and Is a Reovirus Infection a Prime Cause of Celiac Disease? Now there is even more evidence to support such a connection.

A team of Norwegian researchers recently set out to learn whether early exposure to common intestinal viruses, specifically human enterovirus or adenovirus, are factors in the later development of celiac disease.
The research team included Christian R Kahrs, Katerina Chuda, German Tapia, Lars C Stene, Karl Mårild, Trond Rasmussen, Kjersti S Rønningen, Knut E A Lundin, Lenka Kramna,...

What's the Connection Between Infection, Antibiotic Exposure, and Celiac Disease Risk?
Celiac.com 12/26/2019 - Earlier studies have suggested a relationship between infection, associated antibiotic exposure, and the risk of celiac disease. However, there hasn't been a comprehensive evaluation of those studies that might help to deliver a clear answer.
To address this, a team of researchers recently conducted a meta-analysis to investigate the relationship between infection, associated antibiotic exposure, and celiac disease risk.
They began looking for relevant studies by searching the PubMed, Embase, and Cochrane databases for articles published through April 2019. They used random effects models to determine overall pooled estimates and 95% confidence intervals (CIs).
Their meta-analysis contained 19 observational studies, including 15 on infection ...

  Emergency Survival Food - ingredients?
  
  Thank you both. I've done a bit more research (and of course, my facebook feed is now fit for survivalist). Thinking to stock in some backpackers food and maybe a couple of the big cans of vegetables that some of the emergency food sites have. That should all be good at least a couple of years and I can eat them as they near expiration. Water is a good point...

  Severe joint swelling from Celiac
  
  Hello, again. I found this supplement at Amazon that works astoundingly well for pain. The three B vitamins in it, Thiamine B1, Pyridoxine B6, and Cobalamine B12, when taken together relieve pain as well as Nsaids. Not only do I get joint pain (especially in my fingers and can't knit 😿), I get back pain from crushed vertebrae (osteopenia), and th...

  Thanks Scott. I have been using CBD creams, etc. and I do think they help ease the swelling a bit. And thanks so much for creating this forum and for helping those of us who are dealing with a very scary and challenging diagnosis. My path was a bit similar to yours, without so many invasive tests though. I suspect many people suffer for years before getting...
