For Dr. Larry Nixon, that advocacy is deeply personal.
The anesthesiologist has spent more than two decades advocating for greater awareness and research after learning his son, Jaden, was born with sickle cell disease.
"When I found out, I was kind of shocked because all my life I didn't think I had the trait."
That diagnosis led Nixon and his family to establish an advocacy organization focused on education and the search for a cure.
"We were focused on bringing awareness about we want a cure,” said Nixon. “It's reasonable to think that we should have one."
Although treatments have improved, Nixon believes public awareness still lags behind.
"Every opportunity that you have to get behind and to support it... there lies the voice."
He also hopes more people recognize that patients deserve compassion and respect.
"It's affecting another human being. Because people make it about African American disease in their mind, they don't think it's worthy,” said Nixon. “Remind them that this is a patient first, not a Black patient, but a patient that's worth their respect and shouldn't be riddled with the assumptions you may have about them.”
His son, Jaden Nixon, now 24, has carried that message into adulthood.
Living with sickle cell has meant learning how to manage pain, medications and hospital visits while becoming his own advocate.
"It obviously hasn't been easy. I deal with a lot of pain and a lot of crises," said Nixon. “In some cases I have to go to the hospital. Going to the hospital has caused me to miss school sometimes and just miss out on various life things.”
He credits healthy habits with reducing many of those painful episodes.
“I started going to gym when I got to college and I think when I got to college, surprisingly, that's probably been like the healthiest I've been,” said Nixon. “I think it's because I started being more conscious about taking care of my body and I started working out. I started becoming a little bit more physically fit. I've had less pain crises."
Working in health care has also revealed how much education is still needed.
“I had to be a little bit more of a more advocate when I was at Xavier just because I don't think I might have met maybe one other person on campus that had sickle-cell disease,” Nixon said. “I've worked and did rotations at hospitals and I've met doctors that knew about sickle cell but they didn't know exactly how the pain affected the patient.”
For Nixon, World Sickle Cell Day is about ensuring no family feels invisible.
“Use the data to teach people about what the disease is. We have social media, the number one issue with the disease is just people not knowing about it,” said Nixon. “When I complete nursing school, I will be in that hospital environment where I probably will run into sickle cell patients. So I just think just me even doing that can even help spread more awareness about the disease and me being a sickle-cell patient myself, I can have that direct contact with other sickle cell patients and help them navigate their life through the disease.”
