5 lessons I’ve learned from rheumatoid arthritis and why I’m grateful to scientists who can change my world

Angela Durazo was a rising star triathlete—racking up age-group wins and corporate sponsorships. Then a diagnosis with rheumatoid arthritis, an autoimmune disorder caused by the immune system attacking healthy tissue, turned her life upside down. Here, she shares her story—including her new journey as a race car driver—and explains why research taking place at Institutes such as Sanford Burnham Prebys is critical to developing medicines that could help her and the 350 million people worldwide who live with the condition. 

I never thought of myself as an athlete. I was a cheerleader in high school and then participated in basketball for fun, but I wasn’t invested in the sports. Then some years and trials and tribulations later, seeking to find strength within myself, I accepted an invitation to cheer on a friend and I witnessed a triathlon. 

Instantly something spoke to me. The grit, determination, discipline. I was immediately enamored. I needed to do one, but I didn’t know if I could do it. All I knew was I had to try. And so I did. And it was in triathlon, where I truly found myself. Until a diagnosis rocked my world. 

Before I was diagnosed—a journey in itself—I’d never heard of rheumatoid arthritis (RA). No one in my family had it. No one in my life had it. However, I would soon come to find what living with this disease meant. I wouldn’t wish it on my worst enemy. 

First, I noticed stiffness in my hands when I woke up. I thought I might have slept on them wrong. But it kept happening night after night after night. Then it started affecting my workouts. During my runs, I started feeling like I had sandbags strapped around my legs. Unspeakable, unrelenting pain in my arm started. It felt—and still feels during a flare up—like someone is scraping my bone with a hot knife.  

Unable to keep up with training due to the pain and fatigue, I retired from triathlon after seven years. Little did I know the journey that would unfold next—taking me through dozens of doctors, two more career changes (I had a brief endeavor in acting in which I won a Best Actress Award for lead actress in an International feature film) and ultimately leading me to my life’s passion: race car driving. 

My experience continues to teach me so much. Now, nearly ten years after my diagnosis, I feel like I’ve finally crawled my way out of hell. To a healthy person, that may sound like an exaggeration. But to anyone who struggles with RA or any chronic diseases, they will know exactly what I mean.

Here are five lessons I have learned as a person reclaiming my life despite living with RA:

Trust yourself. I knew in my heart that something was deeply wrong. However, as a young, seemingly healthy athlete, doctors thought I was simply overtraining. One even floated the idea that I was a hypochondriac (I won’t repeat what I told that doctor.) Finally, after a year and a half of doctor visits, I stumbled across the term “rheumatoid arthritis” on the Internet. I convinced my doctor to test for RA and I finally had my answer. It couldn’t come soon enough: At this point my hands had begun to puff and distend (ulnar deviation). 

RA is a disability. When I started competing in paratriathlons, created for people with physical disability, some people questioned if I was really disabled. What these individuals didn’t understand is that—even though invisible from the outside—RA caused permanent damage to my mobility. In addition to the arthritis, it eroded my tendons and bursas (fluid-filled sacs that cushion the bone). Even when medicated, I couldn’t rely on my body. One day you can be fine and the next day you aren’t. One day I could run like a gazelle and the next day I feel like I have sandbags on my legs. My coach and those closest to me saw these effects firsthand. In fact, arthritis is a leading cause of work disability in the U.S., according to the Centers for Disease Control and Prevention (CDC).

Your disease does not define you. I still get chills when I think about the moment that I sat in a Formula race car for the first time. This was eight years after my diagnosis. I felt like I had found my spirit that had been missing since my retirement from triathlon. Race car driving is tough on my hands—Formula cars do not have power steering, amplified by G-forces generated by driving more than 160 miles per hour. I have to work twice as hard to keep my strength up. But frankly, I would work three times as hard if needed. I am not letting RA prevent me from pursuing my passion. 

Develop healthy coping skills. Between doctors saying that you won’t walk again and often having to prove your illness, paying attention to mental health is incredibly important for people with RA or any chronic disease. I struggled deeply with depression—and at one point alcohol—and I know many others who also struggle with unhealthy coping mechanisms. Find your support group. Go to therapy. I went to intensive trauma therapy for well over a year to accept the loss of my old body and learn how to embrace this new body with RA. One piece of advice that my trauma specialist told me which transcends any health condition: “RA has already taken so much from you, do not let it take anymore. Turn your pain into power and fight.”

When medicines fail, research is hope. New drugs such as biologics are wonderful. I was incredibly hopeful when I first learned about them. But they only work for one-third of patients. For the other two-thirds of the RA population, we are left figuring it out on our own. And there is so much we don’t know—from what triggers the immune system’s attack to why certain people respond to treatments and others don’t. Get engaged in your research foundations. Attend events. Join Facebook groups. And don’t be afraid to ask questions. YOU are your biggest advocate.

I took this year off racing to heal my body with an experimental treatment, which is working. Now, I’m recalibrating and looking forward to next year’s adventure—IndyCar development—and taking some podiums! 

I believe whole heartedly that one-day we will have a cure for RA. Until then, I hope that others with RA know they aren’t alone, and that as long as autoimmune research advances at Institutes such as Sanford Burnham Prebys, we have hope for the future.

Rheumatoid arthritis drug works by restoring balance to immune cells

In rheumatoid arthritis, the immune system’s patrollers—T cells—see the membrane that surrounds joints as a threat, and engage other immune cells to destroy it. Worse, those misguided T cells become hyperactive. Instead of dying when they should, they continue to fuel inflammation that breaks down the joint tissue.

Scientists led by Salvatore Albani, MD, PhD, an adjunct professor in the Immunity and Pathogenesis Program, have now found a way to return these manic, long-lived T cells to normal—and conveniently, in a drug called hydroxychloroquine, which is already approved to treat symptoms of rheumatoid arthritis. The new results are published in the European Journal of Immunology.

“Hydroxychloroquine is already being used to treat various autoimmune diseases including rheumatoid arthritis,” said Albani. “But, by revealing its mechanisms, we will now be able to develop a better drug for these disabling diseases.”

Rheumatoid arthritis is one of the most common autoimmune diseases, affecting 1.5 million adults in the U.S. Severe joint pain, swelling and stiffness make it challenging for patients to accomplish everyday tasks, and many are easily fatigued. Even with new treatments that have become available in recent years, only 20-40% of patients can keep symptoms at bay over the long term.

 

In the new study, Albani and his team wondered how overactive T cells survive in rheumatoid arthritis. They realized that the cells might require more energy and molecular building blocks than they could generate using standard metabolic pathways. An important cellular process called autophagy—the breakdown of large molecules and organelles for reuse, which is ramped up during starvation—was the first place they thought to look.

Just as they suspected, rates of autophagy were higher in the T cells of patients with rheumatoid arthritis, compared with healthy individuals. Applying hydroxychloroquine to those T cells restored their normal lifespans. The researchers also used a well-established mouse model of rheumatoid arthritis to show that hydroxychloroquine reduced joint swelling.

According to Albani, not all patients respond to hydroxychloroquine. “We think it may work best at early stages of the disease, when T cells are most important,” he said. “We plan to further explore that possibility, as well as ways to improve the outcomes of treating rheumatoid arthritis with autophagy inhibitors.”

Structure of immune-regulating ubiquitin ligase solved

Scientists at SBP have solved the atomic structure of a unique ubiquitin ligase complex that attaches ubiquitins to proteins in linear chains. The study, published in Nature, opens the door for developing a novel class of drug targets for cancer as well as inflammatory diseases such as rheumatoid arthritis, Crohn’s disease and psoriasis.

“Our new research revealing the fully active structure of HOIP, an RBR E3 ligase, holds significant therapeutic potential in oncology and immunology,” said Bernhard Lechtenberg, PhD, postdoctoral fellow at SBP and lead author of the study. “The three-dimensional structure we present provides detailed insights into the molecular architecture of the complex and allows us to draw conclusions about how it works.”

Ubiquitin is a small protein that helps regulate the function of other proteins in the body. E3 ligases carry out a process known as ubiquitination, where ubiquitin is attached to a substrate protein, changing the way it functions. Ubiquitin is best known for its role in protein degradation, but has more recently been recognized as important for regulating the activity of proteins involved in cell signaling, DNA repair, anti-inflammatory, and immune responses.

There are three classes of E3 ligases, but members of the RBR type have most recently emerged as a novel and relatively untapped class of targets for drug discovery because of their role in modulating the immune system.

“We were surprised to find how the active form of the E3 ligase we analyzed, called HOIP, attaches ubiquitin in a markedly different way—an elongated fashion—compared to the other types of E3 ligases,” said Stefan Riedl, PhD, associate professor in SBP’s NCI-designated Cancer Center and senior author of the paper. “This may be key to its role in activating the NF-kB pathway, a signaling process that is well established as a regulator of cell survival and death, and helps coordinate the immune system.

“NF-kB is the master regulator of inflammation inside cells, and its activation is believed to promote cancer development by inhibiting cell death and promoting inflammation. This study removes a significant technical barrier that has prevented exploiting RBR E3 ligases as a drug target for cancer and inflammatory disorders.

“Our next step is to continue to work very closely with our biology and immunology collaborators to more fully understand the regulation of RBR E3 ligases,” added Riedl.

The study was performed in collaboration with Ruslan Sanishvili at the Argonne National Laboratory and Peter Mace at the University of Otago, New Zealand. The full text is available here.
