New Blood Tests For IBS Offer Quicker Diagnosis

Irritable bowel syndrome is a strongly related condition to interstitial cystitis and chronic pelvic pain. If you’re like most patients, you’ve probably faced doctors (and family members) who simply didn’t believe you and/or who may have suggested that this was a mental or psychiatric disorder. Not true and now we have concrete evidence that will help establish a diagnosis of IBS. Researchers in LA have developed two new blood tests that have identified IBS with a 90% accuracy rate by looking for two antibodies commonly found in their blood stream. It took me ten years and a lot of tears before I received my diagnosis of IC. I am thrilled to see that patients will now have the opportunity to be diagnosed quickly and compassionately.  Here’s a great video about it as well as the official press release. – Jill O.

New Blood Tests Will Speed up Diagnosis for the Most Common GI Disorder

Newswise — LOS ANGELES (May 14, 2015) – Millions of people afflicted by irritable bowel syndrome can now be diagnosed quickly and accurately with two simple blood tests developed by a Cedars-Sinai gastroenterologist. The tests, created by Mark Pimentel, MD, director of the GI Motility Program and Laboratory, confirm when a patient has developed IBS because of food poisoning, a major cause of the disorder.

Toxins produced by bacteria, such as salmonella, can severely harm the digestive system by damaging nerves critical to healthy gut function. The new blood tests identify the presence and amount of specific antibodies reacting to the toxins. “Having an early diagnosis means patients can avoid years of invasive tests and visits to specialists that often leave them with more questions than answers,” he said. “With these new blood tests, many patients will now be able to proceed right to therapy for their condition.”

IBS is the most common gastroenterological disorder in the United States, affecting nearly 40 million people. An estimated 10 percent of the world’s population suffers from the condition. The disorder, nearly impossible to diagnose until now, is characterized by a cluster of confounding symptoms that include chronic bloating, abdominal pain, gas, and bouts of relentless diarrhea, constipation, or both. Fatigue and the stress of trying to plan one’s life around visits to the bathroom can be debilitating.

A multicenter study validating the accuracy of the new blood tests, “Development and Validation of a Biomarker for Diarrhea-Predominant Irritable Bowel Syndrome in Human Subjects,” was published this week in the journal PLOS ONE. Pimentel will also present the research on Sunday, May 17th, at Digestive Disease Week 2015 in Washington, D.C. Pimentel and fellow researchers studied nearly 3,000 people, comparing IBS patients to those diagnosed with inflammatory bowel disease, celiac disease and those with no GI disease. The blood tests identified the two antibodies associated with IBS — anti-Cdtb and anti-vinculin — with greater than 90 percent certainty. The tests are marketed under the name IBSchek™ and are produced by Commonwealth Laboratories Inc., in Salem, Massachusetts.

“Most IBS patients have been told at one time or another that the disease was psychological, all in their head,” said Pimentel. “The fact that we can now confirm the disease through their blood, not their head, is going to end a lot of the emotional suffering I have seen these patients endure.”

My Google Profile+ Jill Heidi Osborne is the president and founder of the Interstitial Cystitis Network, a health education company dedicated to interstitial cystitis, bladder pain syndrome and other pelvic pain disorders. As the editor and lead author of the ICN and the IC Optimist magazine, Jill is proud of the academic recognition that her website has achieved. The University of London rated the ICN as the top IC website for accuracy, credibility, readability and quality. (Int Urogynecol J - April 2013). Harvard Medical School rated both Medscape and the ICN as the top two websites dedicated to IC. (Urology - Sept 11). Jill currently serves on the Congressionally Directed Medical Research Panel (US Army) where she collaborates with researchers to evaluate new IC research studies for possible funding. Jill has conducted and/or collaborates on a variety of IC research studies on new therapeutics, pain care, sexuality, the use of medical marijuana, menopause and the cost of treatments, shining a light on issues that influence patient quality of life. An IC support group leader and national spokesperson for the past 20 years, she has represented the IC community on radio, TV shows, at medical conferences. She has written hundreds of articles on IC and its related conditions. With a Bachelors Degree in Pharmacology and a Masters in Psychology, Jill was named Presidential Management Intern (aka Fellowship) while in graduate school. (She was unable to earn her PhD due to the onset of her IC.) She spends the majority of her time providing WELLNESS COACHING for patients in need and developing new, internet based educational and support tools for IC patients, including the “Living with IC” video series currently on YouTube and the ICN Food List smartphone app! Jill was diagnosed with IC at the age of 32 but first showed symptoms at the age of 12.
