Widely Used Red Food Dye Linked to IBD

By Pat Anson, PNN Editor

Allura Red is one of the most widely used artificial food dyes in the world. Also known as “Red Dye 40,” the dark red coloring is added to sodas, candies, breakfast cereals, condiments and dozens of other food products to make them more appetizing.

Over the years, Allura Red has been linked to a variety of different health conditions, including attention deficit hyperactivity disorder (ADHD) in children. Now there is emerging evidence that Allura Red may also trigger inflammatory bowel diseases (IBDs) such as Crohn’s and ulcerative colitis.

Researchers at McMaster University in Ontario, Canada exposed laboratory mice to Allura Red for 12 weeks — at about the same levels humans might consume — and found that it caused chronic inflammation in their gastrointestinal tracts and raised levels of serotonin, a hormone that affects mood and digestion.

“This study demonstrates significant harmful effects of Allura Red on gut health and identifies gut serotonin as a critical factor mediating these effects. These findings have important implication in the prevention and management of gut inflammation,” McMaster researcher Waliul Khan, PhD, said in a statement.

“What we have found is striking and alarming, as this common synthetic food dye is a possible dietary trigger for IBDs. This research is a significant advance in alerting the public on the potential harms of food dyes that we consume daily.”

Although Allura Red and eight other synthetic food dyes – all derived from petroleum -- are considered “safe for the general population” by the FDA, there have been relatively few studies of their effect on human health. Some experts believe the dyes disrupt the absorption of key minerals like zinc and iron, causing hyperactivity, allergic reactions and gut inflammation.

STRAWBERRY SODA CONTAINING ALLURA RED DYE

Recent research has helped establish the importance of gut health, and that bacteria can have profound effects – both harmful and beneficial -- on our immune and gastrointestinal systems. A 2022 study, for example, found evidence that a particular strain of bacteria causes abdominal pain, cramps, bloating, gas and diarrhea – symptoms common to IBD. A 2019 study linked gut bacteria to fibromyalgia.

Western diets that have a lot of processed food rich in fat, meat and sugar have also been linked to gut inflammation. Processed foods tend to have a lot of Allura Red and other chemical additives, and Khan believes they warrant further study.

“The literature suggests that the consumption of Allura Red also affects certain allergies, immune disorders and behavioural problems in children, such as attention deficit hyperactivity disorder,” said Khan, a professor of Pathology and Molecular Medicine at McMaster and principal investigator at the Farncombe Family Digestive Health Research Institute.

Khan and his colleagues published their findings in Nature Communications. Their study was funded by the Canadian Institutes of Health Research.

Pain Warrior: A Tribute to Sherri Little

(Editor’s note: This week marks the first anniversary of the death of Sherri Little, a 53-year old California woman who took her own life, after years of struggle with chronic pain and depression. Suicide is a difficult but important issue to address in the pain community, and our story about Sherri’s final days (“Sherri’s Story: A Final Plea for Help”) touched many readers. Tina Petrova was a friend of Sherri’s and wrote the following tribute to her.)   

By Tina Petrova, Guest Columnist

Sherri L. Little was a stunningly beautiful, diminutive blonde with sparkling, mischievous eyes. We became fast friends on Facebook, united by our common passion of pain patient advocacy.

She initially reached out to me after hearing that I had a film in development on chronic pain, saying, “Do I have a story for you!”

And indeed, she did.

Sherri was one of those rare people who could light up a room upon entering. She possessed charisma in spades and emanated a childlike wonder and joy.

SHERRI LITTLE

During the all too short time I knew Sherri, her key focus was advocating for pain patients, speaking up, and getting involved. Her search for treatments for her own painful conditions (occipital neuralgia, fibromyalgia and complicated IBS) took a back seat to her passion to help others.

I had the pleasure and honor of hosting Sherri in Toronto, Canada in May 2015. She made the long trek from Mexico where she was staying, to New York City to participate in the 2015 Caterpillar Walk for fibromyalgia, travelling onwards to me. 

SHERRI AND TINA PETROVA

I drove her around to my own treating doctors, hoping she could benefit from those who had greatly helped me. We filmed a short interview with her, which is to become a key centerpiece in our upcoming documentary.

It was Sherri’s final wish that we tell her story to the world.

Despite sleep deprived nights and painful days, she took delight in all the small activities I had planned during her stay with me, such as lunching at a vegetarian restaurant.

It surprised me that such small gestures could be so impactful for her, until she explained that her adult relationships thus far had not supported her pained life. She shared with me that she longed for deep, authentic connections.

Sherri was to return to Toronto in September 2015 to continue the interview process. Sadly, this was not to be.  

Sherri was found dead on July 7, 2015, after a July 4th weekend attempt to get medical help at a hospital in Los Angeles. Unable to eat and drink for four weeks, she had taken a solo train trip to L.A. from San Diego, hiring a patient advocate to champion her rights.

Her last ditch hope with faltering health was that she would gain access to the specialists and treatment she so badly needed to live her life with any quality. For reasons her family and I still cannot fathom or piece together, Sherri left the hospital and checked into a hotel room across the street, alone and in pain. We will never know for certain what transpired in those final hours.

Having a previous diagnosis of Clostridium difficile colitis and suffering from severe abdominal pain, she had been unable to keep food down for over a month and was existing solely on raw juices.

Her mom told me she had driven down to San Diego to take her daughter to the hospital on more than one occasion for horrible bowel pain and dehydration. After giving Sherri an IV drip in the ER, they released her home on each occasion.

In honor of Sherri’s courageous battle with chronic pain, we will be dedicating “Pandemic of Denial” to Sherri and her fight for better pain care for our community.

Sherri’s laughter will no longer echo in the halls of life, but I’m sure she’s busy keeping the angels on their toes in heaven with her loving heart and her shining soul of activism.

I can just see her high above us saying, “But you have to DO SOMETHING!”

And with that, we are. Sherri, you are loved and missed dearly.

Tina Petrova is an award winning filmmaker, pain patient and chronic pain activist.

Tina co- founded Give Pain A Voice in 2014 with Bob Schubring, to champion the rights of pain patients everywhere.

“Pandemic of Denial” is currently in production with plans for release in 2017. We have created a website to honor Sherri’s memory, which you can see by clicking here.

New Molecules May Combat Immune System Disease

By Pat Anson, Editor

A team of international researchers may have unlocked an ancient secret in the human immune system that could lead to new treatments for rheumatoid arthritis, multiple sclerosis and inflammatory bowel disease (IBD).

"Innate immunity is so old it goes all the way down to frogs, fish and even insects," says Professor Matt Cooper of the University of Queensland’s Institute of Molecular Bioscience.

Cooper and colleagues at Kings College London and the U. S. National Institutes of Health say the human immune system is basically comprised of two parts: the adaptive immune system, which produces antibodies against infection, and a very ancient pathway, known as the innate immune system.

"It stops us getting infections, but it also drives a lot of inflammatory diseases,” explains Cooper.  "So, in one case it's keeping us alive by stopping the bugs getting us, but if it goes wrong, we start to get diseases like arthritis, multiple sclerosis and IBDs such as colitis.

"Researchers always thought key components of these pathways acted alone, but our teams have discovered they can communicate and work together."

IBD is a chronic and painful inflammation of the gastrointestinal tract. Inflammation affects the entire digestive tract in Crohn’s disease, but only the large intestine in ulcerative colitis.

The study findings, published in the journal Science, may have significant implications for treating millions of people who suffer from inflammatory diseases.

"Inflammation in diseases such as colitis occurs when the immune system is activated inappropriately, and causes symptoms including pain, diarrhea, fever and weight loss," said Cooper. "Current treatments are not always effective, possibly because they are only blocking one of the key pathways and inflammation still occurs through the other pathway."

Researchers have developed two small molecules that each block one pathway.

activated immune cells

"We have tested these molecules and the results show that they both reduce inflammation when administered separately," Cooper said. "This work is still in the early stages but we are hopeful our ongoing research will lead to more effective treatments for the millions of IBD sufferers.

"It may give other scientists opportunities to develop new drugs against these diseases."

A healthy immune system is activated when the body recognizes invading microbes and alerts immune cells, such as T cells. Disease begins when the immune response spirals out of control and begins attacking healthy tissue.  

Researchers at New York University’s Langone Medical Center are also working on a theory known as the "hygiene hypothesis" that may explain why there is an increase in inflammatory bowel disease worldwide. They believe intestinal parasites and bacteria that humans were long exposed to are beneficial and help balance the immune system.

Sanitary practices have sharply reduced these parasitic and bacterial infections in developed nations, which now have some of the highest rates of Crohn’s and colitis. Researchers believe the immune response to infections triggers the growth of Clostridia, a bacterium known to counter inflammation.

Does Washing Your Hands Raise Risk of IBD?

By Pat Anson, Editor

Many of us were taught as children to always wash our hands before leaving the bathroom and before meals. But that basic sanitary practice may be contributing to an increase in inflammatory bowel diseases (IBD) such as Crohn’s disease and ulcerative colitis, according to a new study published in the journal Science.

Researchers at New York University’s Langone Medical Center tested the so-called “hygiene hypothesis” – the theory that some intestinal parasites and bacteria are beneficial because they help balance the immune system and reduce IBD rates. Sanitary practices have sharply reduced gut worm infections in developed nations, which now have some of the highest rates of Crohn’s disease and ulcerative colitis.

“Our findings are among the first to link parasites and bacteria to the origin of IBD, supporting the hygiene hypothesis,” says parasitologist P’ng Loke, PhD, an associate professor at NYU Langone.

“The prevalence of IBD is much less in regions of the world which have heavy worm infection. In fact, I got interested in the question of how worms can be beneficial when I was contacted by an individual who had deliberately infected himself with worms to treat his symptoms of IBD and was able to put his disease into remission.”

Loke and his colleagues found that laboratory mice infected with intestinal worms experienced a thousand-fold decrease in Bacteroides — a type of bacteria linked to people with higher risk of IBD. At the same time, the number of Clostridia, a bacterium known to counter inflammation, increased tenfold in the mice.

RESEARCHERS P'ng Loke and Ken Cadwell, NYU Langone Medical Center

Researchers believe the immune response to the worms triggers the growth of Clostridia, which then either outcompete Bacteroides for nutrients or release toxins that are harmful to them.

In a second phase of the study, researchers gave mice an infusion of Clostridia – without the use of parasites – and found that it reduced the presence of Bacteroides.

“That gives us a lot of hope in terms of IBD therapy because maybe we don’t need to give people parasitic worms, which can be harmful and cause disease, and instead target the harmful bacteria by replacing them with healthy bacteria,” says microbiologist Ken Cadwell, PhD, an assistant professor at NYU Langone and the Skirball Institute of Biomolecular Medicine. “Our study could change how scientists and physicians think about treating IBD.”

Researchers say the hygiene hypothesis may also apply to other autoimmune diseases, including multiple sclerosis, rheumatoid arthritis, and type 1 diabetes, in which processes meant to attack foreign invaders instead become oversensitive and trigger an immune response to the body’s own cells.

IBD is a chronic or recurring immune response and a painful inflammation of the gastrointestinal tract. Inflammation affects the entire digestive tract in Crohn’s disease, but only the large intestine in ulcerative colitis.

According to the Crohn's and Colitis Foundation of America, IBD affects about 1.6 million Americans and tends to run in families. Caucasians are more likely than other ethnic groups to have IBD. The diseases are especially prevalent in Jews of European descent (Ashkenazi Jews). African Americans and Hispanics in the United States are also increasingly affected.

Sherri’s Story: A Final Plea for Help

By Pat Anson, Editor

“I’ve been thinking about ending my life if I don’t get the help I need.”

Those are chilling words for anyone to hear. And in the last two years of her life, Sherri Little said them often to family, friends and doctors.  After decades of struggling with chronic pain from fibromyalgia, inflammatory bowel disease, severe colitis and other conditions, the 53-year old California woman was desperate and depressed when she checked into the emergency room at Cedars-Sinai Medical Center in Los Angeles on July 3, 2015.

What happened over the next four days is not entirely clear, but we know that Sherri took her own life. Her body was found in the bathtub of a hotel room across the street from Cedars-Sinai on the morning of July 7, with several prescription bottles and an empty bottle of wine nearby. Sherri had been sober for many years.

“I attest this is the first drink of alcohol in 16 years -- just to give me the courage to end my life alone,” Sherri wrote in a suicide note found in her hotel room.

“Several documents found inside the location underscored her pain, suffering and suicidal ideations,” reads the coroner’s report. “A check of the decedent’s laptop also contained a pictured document written by the decedent titled ‘Why I Killed Myself’ by Sherri Little.”

We’re telling Sherri’s story --- with the help of her mother, friends and patient advocate – not in a ghoulish attempt to recreate her final days, but to lend a name, a face and a voice to the untold number of chronic pain sufferers who have also been overwhelmed by pain, depression and loss of hope.  Like Sherri, many felt abandoned by a healthcare system that was unwilling or simply unable to treat them.

sherri little

Over 42,000 Americans killed themselves in 2014 according to the CDC, but experts believe the actual number is higher. Many suicides go unreported or are misclassified as accidental, covered up by grieving family members or accommodating medical examiners.

Sherri’s death was no accident, but it’s taken several months for her mother to come to terms with it.

“I’ve got to get her story out there,” said Lynda Mannion, Sherri’s mother. “She got to the point in the last year or so she could hardly eat solid food at all. She was just drinking her nutrition. I guess she must have lost 20 to 30 pounds in the last year.

“She would say, ‘I can’t go on living like this. If I can’t get some help, if somebody doesn’t believe me, I just can’t go on living like this.’ She didn’t seem to be extremely afraid of dying, considering the alternative, living with the pain she was in. But I never expected her to do it.”

A few months before she died, Sherri gave an interview to Tina Petrova in Toronto for a soon-to-be released documentary called Pain Warriors. 

“Sherri Little and I first became friends on Facebook, united by our common passion of pain patient advocacy. She initially reached out to me after hearing that I had a film in development I was producing on chronic pain and said, ‘Do I have a story for you!’ And indeed, she did,” says Petrova.

In this short clip, Sherri doesn’t talk about suicide and appears hopeful about her future.

But just weeks later, Sherri wrote the following in an email to Petrova:

“I was acutely suicidal last night after being verbally abused by a doctor who can't even get me any pain relief anymore,” said Sherri. “In a last ditch effort to save my life I am going to Cedar Sinai ER in LA with my patient advocate.”

Sherri was referring to Lisa Blackstock, a professional advocate who founded Soul Sherpa to help guide patients through the healthcare system. Blackstock had been a volunteer at Cedars-Sinai for several years and knew her way around one of the most respected hospitals in Los Angeles. 

The day before she went to the hospital, Sherri was still having suicidal thoughts.

“I woke at 3am today, ready to give up the fight and end my life. This is not dramatic or blaming of you, but just a statement of fact: my life has not been worth living for 2 years,” Sherri wrote in an email to Blackstock.

The two women went to Cedars-Sinai together and were in the emergency room for 11 hours before Sherri was finally admitted as a patient with severe abdominal pain on the evening of July 3rd.

Over the next two days, Sherri was examined by doctors and a psychiatrist, who concluded she was a “moderate” suicide risk because she had never actually tried to take her own life.

“Patient is at moderate risk of harm to self, but does not meet criteria for involuntary psychiatric treatment at this time,” the psychiatrist wrote in Sherri’s medical records, which were provided to Pain News Network by her mother.

cedars-sinai medical center

Sherri was scheduled for a colonoscopy on July 6, but never had the procedure.  For reasons that are not clear, she became frustrated with her treatment and left the hospital the night before.

“She left against medical advice,” Sherri’s discharge notes say. “Efforts were made to talk to her about the seriousness of her decision. She explained that she understood but, however, would like to leave against medical advice.”

Lisa Blackstock didn’t learn about Sherri’s release until it was too late.

“Despite a HIPAA release (patient release form) on file naming me as Sherri's contact, the doctor did not contact me and decided there was no reason to place her on a 72-hour involuntary hold,” Blackstock wrote in a letter to the coroner’s investigator. “Sherri was allowed to leave the hospital, in pain and suicidal, and the physicians responsible for her care failed miserably.

“I am a long-term volunteer at Cedars, and, until this incident, had great respect for them.  Changes in healthcare law have resulted in substandard care for many patients depending upon their insurance coverage types, as well as hospital administrators dictating care for patients rather than skilled physicians.”

A spokeswoman for Cedars-Sinai said the hospital was unable to comment and wouldn’t even confirm Sherri had been a patient there.

“State and federal privacy laws prevent hospitals from releasing information about patients without their consent, including whether an individual may or may not be a current or former patient,” wrote Sally Stewart in an email to PNN.

Cocktail of Medications

Long before she was admitted to Cedars-Sinai, Sherri was prescribed a potent cocktail of medications for her pain and depression; including the opioids tramadol and hydrocodone, as well as Lyrica (pregabalin), Ambien (zolpidem), and Klonopin (clonazepam).    

Lyrica, Ambien and Klonopin have all been linked to increased risk of suicide.  

Lyrica has an FDA warning label that states the drug “may cause suicidal thoughts or actions” and Ambien’s label warns that “depression or suicidal thinking may occur.”

Klonopin belongs to a class of sedatives known as benzodiazepines, which are increasingly being linked to overdoses, especially when combined with opioids. Klonopin’s label also warns of “suicidal behavior and ideation.”

Why were doctors prescribing these drugs to someone who was suicidal? And why did Cedars-Sinai release Sherri with the drugs in her possession?

“They discharged her with all of them at Cedars, which I found just incredibly irresponsible,” says Blackstock.

According to the autopsy report, the coroner found only trace amounts of opioids and Ambien in Sherri’s system, but apparently never looked for the other drugs. Her official cause of death is listed vaguely as “combined effects of medications.”

Were the same drugs that Sherri took for her pain and depression – which were ineffective in helping either – used as instruments in her death? 

We may never know the answer.

“I have fought to get help for the disease I am dying of – pseudomembranous colitis – for years without help from anyone,” Sherri wrote in her suicide note. “I do not want to be resuscitated. There is nothing left for me but to be tied to a hospital bed in great pain.” 

Sherri was divorced and did not have any children. But a close circle of friends and loved ones are anxious to have her story told and her memory preserved.

“She was beautiful from the time she was little. She was beautiful up to the day she died.  She looked 20 years younger than she was,” recalls Sherri’s mother, Lynda.

“She loved to help people. She wanted to help people and she couldn’t understand why nobody would help her. She would have been there for anybody.”

“Sherri was one of those rare people that could light up the room upon entering,” recalls her friend, Tina Petrova. “During the all too short time I knew Sherri, her key focus above all was advocating for pain patients, speaking up, getting involved. Her search for treatments for her own painful conditions took a back seat to her passion to help others.

“I can just see her high above us saying, “But you have to DO SOMETHING!’”

Sherri’s advocacy will continue, thanks to a website Petrova created to honor Sherri's memory and the documentary that she’s producing on chronic pain in North America.

What can the rest of us learn from Sherri’s struggle?

Perhaps those lessons are best learned through her own words -- and the advice that Sherri gave to other pain sufferers:

Accepting Chronic Pain: Is it Necessary?

By Jennifer Martin, Columnist

A patient of mine told me the other day, “I don’t think I will ever be able to accept my chronic pain. It has completely changed my life.” 

I think this is something that most people with chronic pain contend with at some point in time; wanting to hold onto hope that their diagnosis isn’t chronic or not wanting to come to the realization that they will have to live with the pain forever.

When most people hear the word “acceptance” they equate it with the notion that they should feel that it’s okay or it’s alright to have a chronic condition.  Many people don’t ever feel okay about having to live with pain or an illness for the rest of their lives. It is not something that is easy to get used to and it’s not fair.

• Accepting chronic pain does not mean giving into it and it doesn’t mean that you stop looking for treatment.
• Accepting chronic pain does not mean accepting a lifetime of suffering.
• Accepting chronic pain does not mean you are never allowed to feel angry or sad.
• Accepting chronic pain does not mean that you have to give up hope for the future.

When I use the word “acceptance,” I mean accepting the reality of your situation and recognizing that this new reality could be permanent. Those of us with chronic conditions may never like this reality and it may never be okay, but eventually it is necessary to accept it and learn to live life with it. It is the new norm with which we must learn to live.

Acceptance also involves making adaptations and alterations to our lives.  We must find new things that bring us joy and we must have hope for the future.

• Accepting chronic pain means learning to live again.
• Accepting chronic pain means advocating for ourselves and our health so that we can be as healthy as possible.
• Accepting chronic pain means learning our limits and learning to cope with feelings of guilt when we have to say “no.”
• Accepting chronic pain means being able to look at your diagnosis as something you have, not who you are.  Your condition does not define you.
• Accepting chronic pain means re-evaluating your role as a husband/wife, mother/father, etc. as well as your life’s goals -- and figuring out how you can maintain these roles and attain your goals with your chronic condition.

For many of us, learning to accept our chronic condition isn’t easy.  It is a learning process with a lot of ups and downs.  It is something we may resist and something we may think impossible.  It is difficult to accept something that has completely changed our lives and possibly the direction we thought our life was going to take.

Why is it necessary to accept your chronic condition?

Once you are diagnosed with a chronic condition, it will be always be with you.  The sooner you are able to begin the process of acceptance, the sooner you will be able to learn exactly how to live with it.  It is also how you will learn to cope.

Accepting chronic pain means learning to live life in a different way than before your diagnosis.  It means learning to pace your activities, educating yourself, taking your medications, advocating for yourself, and surrounding yourself with support.  It also means accepting that some aspects of your condition are out of your control. 

Chronic pain can be unpredictable.  There may be days when you feel in control of your pain and you are able to accomplish everything you would like to.  There may also be days when your pain is unbearable, you feel angry about your situation, and all you can do is rest.  Accepting your chronic pain means adjusting and adapting to the ways in which your life is different now that you may be living with this kind of unpredictability.

Your life may never go back to what it was prior to your chronic pain.  But that doesn’t mean you can’t live a happy, successful, hopeful life with pain.  Learning to accept your chronic pain can help you get there.
