A New Test Aims to Objectively Measure Pain. It Could Help Legitimate Sufferers Access the Meds They Need.
Sickle cell patient Bridgett Willkie found herself being labeled an addict when she sought an opioid prescription to control her pain.
"That throbbing you feel for the first minute after a door slams on your finger."
This is how Central Florida resident Bridgett Willkie describes the attacks of pain caused by her sickle cell anemia – a genetic blood disorder in which a patient's red blood cells become shaped like sickles and get stuck in blood vessels, thereby obstructing the flow of blood and oxygen.
"I found myself being labeled as an addict and I never was."
Willkie's lifelong battle with the condition has led to avascular necrosis in both of her shoulders, hips, knees and ankles. This means that her bone tissue is dying due to insufficient blood supply (sickle cell anemia is among the medical conditions that can decrease blood flow to one's bones).
"That adds to the pain significantly," she says. "Every time my heart beats, it hurts. And the pain moves. It follows the path of circulation. I liken it to a traffic jam in my veins."
For more than a decade, she received prescriptions for Oxycontin. Then, four years ago, her hematologist – who had been her doctor for 18 years – suffered a fatal heart attack. She says her longtime doctor's replacement lacked experience treating sickle cell patients and was uncomfortable writing her a prescription for opioids. What's more, this new doctor wanted to place her in a drug rehab facility.
"Because I refused to go, he stopped writing my scripts," she says. The ensuing three months were spent at home, detoxing. She describes the pain as unbearable. "Sometimes I just wanted to die."
One of the effects of the opioid epidemic is that many legitimate pain patients have seen their opioids significantly reduced or downright discontinued because of their doctors' fears of over-prescribing addictive medications.
"I found myself being labeled as an addict and I never was...Being treated like a drug-seeking patient is degrading and humiliating," says Willkie, who adds that when she is at the hospital, "it's exhausting arguing with the doctors...You dread them making their rounds because every day they come in talking about weaning you off your meds."
Situations such as these are fraught with tension between patients and doctors, who must remain wary about the risk of over-prescribing powerful and addictive medications. Adding to the complexity is that it can be very difficult to reliably assess a patient's level of physical pain.
However, this difficulty may soon decline, as Indiana University School of Medicine researchers, led by Dr. Alexander B. Niculescu, have reportedly devised a way to objectively assess physical pain by analyzing biomarkers in a patient's blood sample. The results of a study involving more than 300 participants were published earlier this year in the journal Molecular Psychiatry.
Niculescu – who is both a professor of psychiatry and medical neuroscience at the IU School of Medicine – explains that, when someone is in severe physical pain, a blood sample will show biomarkers related to intracellular adhesion and cell-signaling mechanisms. He adds that some of these biomarkers "have prior convergent evidence from animal or human studies for involvement in pain."
Aside from reliably measuring pain severity, Niculescu says blood biomarkers can measure the degree of one's response to treatment and also assess the risk of future recurrences of pain. He believes this new method's greatest benefit, however, might be the ability to identify a number of non-opioid medications that a particular patient is likely to respond to, based on his or her biomarker profile.
Clearly, such a method could be a gamechanger for pain patients and the professionals who treat them. As of yet, health workers have been forced to make crucial decisions based on their clinical impressions of patients; such impressions are invariably subjective. A method that enables people to prove the extent of their pain could remove the stigma that many legitimate pain patients face when seeking to obtain their needed medicine. It would also improve their chances of receiving sufficient treatment.
Niculescu says it's "theoretically possible" that there are some conditions which, despite being severe, might not reveal themselves through his testing method. But he also says that, "even if the same molecular markers that are involved in the pain process are not reflected in the blood, there are other indirect markers that should reflect the distress."
Niculescu expects his testing method will be available to the medical community at large within one to three years.
Willkie says she would welcome a reliable pain assessment method. Well-aware that she is not alone in her plight, she has more than 500 Facebook friends with sickle cell disease, and she says that "all of their opioid meds have been restricted or cut" as a result of the opioid crisis. Some now feel compelled to find their opioids "on the streets." She says she personally has never obtained opioids this way. Instead, she relies on marijuana to mitigate her pain.
Niculescu expects his testing method will be available to the medical community at large within one to three years: "It takes a while for things to translate from a lab setting to a commercial testing arena."
In the meantime, for Willkie and other patients, "we have to convince doctors and nurses that we're in pain."
Here's how one doctor overcame extraordinary odds to help create the birth control pill
Dr. Percy Julian had so many personal and professional obstacles throughout his life, it’s amazing he was able to accomplish anything at all. But this hidden figure not only overcame these incredible obstacles, he also laid the foundation for the creation of the birth control pill.
Julian’s first obstacle was growing up in the Jim Crow-era south in the early part of the twentieth century, where racial segregation kept many African-Americans out of schools, libraries, parks, restaurants, and more. Despite limited opportunities and education, Julian was accepted to DePauw University in Indiana, where he majored in chemistry. But in college, Julian encountered another obstacle: he wasn’t allowed to stay in DePauw’s student housing because of segregation. Julian found lodging in an off-campus boarding house that refused to serve him meals. To pay for his room, board, and food, Julian waited tables and fired furnaces while he studied chemistry full-time. Incredibly, he graduated in 1920 as valedictorian of his class.
After graduation, Julian landed a fellowship at Harvard University to study chemistry—but here, Julian ran into yet another obstacle. Harvard thought that white students would resent being taught by Julian, an African-American man, so they withdrew his teaching assistantship. Julian instead decided to complete his PhD at the University of Vienna in Austria. When he did, he became one of the first African Americans to ever receive a PhD in chemistry.
Julian received offers for professorships, fellowships, and jobs throughout the 1930s, due to his impressive qualifications—but these offers were almost always revoked when schools or potential employers found out Julian was black. In one instance, Julian was offered a job at the Institute of Paper Chemistory in Appleton, Wisconsin—but Appleton, like many cities in the United States at the time, was known as a “sundown town,” which meant that black people weren’t allowed to be there after dark. As a result, Julian lost the job.
During this time, Julian became an expert at synthesis, which is the process of turning one substance into another through a series of planned chemical reactions. Julian synthesized a plant compound called physostigmine, which would later become a treatment for an eye disease called glaucoma.
In 1936, Julian was finally able to land—and keep—a job at Glidden, and there he found a way to extract soybean protein. This was used to produce a fire-retardant foam used in fire extinguishers to smother oil and gasoline fires aboard ships and aircraft carriers, and it ended up saving the lives of thousands of soldiers during World War II.
At Glidden, Julian found a way to synthesize human sex hormones such as progesterone, estrogen, and testosterone, from plants. This was a hugely profitable discovery for his company—but it also meant that clinicians now had huge quantities of these hormones, making hormone therapy cheaper and easier to come by. His work also laid the foundation for the creation of hormonal birth control: Without the ability to synthesize these hormones, hormonal birth control would not exist.
Julian left Glidden in the 1950s and formed his own company, called Julian Laboratories, outside of Chicago, where he manufactured steroids and conducted his own research. The company turned profitable within a year, but even so Julian’s obstacles weren’t over. In 1950 and 1951, Julian’s home was firebombed and attacked with dynamite, with his family inside. Julian often had to sit out on the front porch of his home with a shotgun to protect his family from violence.
But despite years of racism and violence, Julian’s story has a happy ending. Julian’s family was eventually welcomed into the neighborhood and protected from future attacks (Julian’s daughter lives there to this day). Julian then became one of the country’s first black millionaires when he sold his company in the 1960s.
When Julian passed away at the age of 76, he had more than 130 chemical patents to his name and left behind a body of work that benefits people to this day.
