Meet Joe - PNH Patient

Meet Joe - Diagnosed with PNH at 24 Years Old

Joe was completing his Master’s degree, engaged to be married, and on his way to becoming a professional mixed martial arts competitor when the symptoms began: unexplained fatigue, dark urine, back and stomach pain. After six weeks of numerous blood tests, Joe was referred to a hematologist who diagnosed him with paroxysmal nocturnal hemoglobinuria (PNH) – an ultra-rare, life-threatening blood disorder in which uncontrolled activation of the complement system leads to the chronic destruction of red blood cells. Historically, approximately one-third of patients with PNH do not survive more than five years from the time of diagnosis.

When Joe was diagnosed, he says that he felt like his dreams were nearly shattered. He was worried that he would not have a future with his fiancée and was told he would never be able to compete in contact sports again. With this news, Joe could have simply thrown in the towel, but he didn’t. Instead, he made it his mission to educate himself and his family about PNH. Fortunately for Joe, his doctors were able to manage his PNH.

“I’ve never been one to back down in a fight, but when I was diagnosed with PNH, the prognosis was overwhelming. I had no choice but to view this disease as yet another challenge – one that I had to overcome. If anything, living with PNH has made me appreciate my time even more, and given me more drive to get back to doing what I love to do.”

Today, Joe shares his story with other patients with PNH to give them hope for the future. Joe is living his life on his own terms; he married his college sweetheart, welcomed the birth of two daughters, and is back in his routine. 

Meet Evie - Diagnosed wiht HPP at 2 Weeks Old

When an ultrasound revealed that Evie had extremely fragile and transparent bones, doctors told expectant parents John and Lindsey that it was not likely their baby girl would live long after birth. The hours that Evie’s parents expected to have with her turned into weeks, but the baby was gripped by seizures. Then, a routine blood draw revealed that Evie had low alkaline phosphatase (ALP), which enabled them to diagnose her with hypophosphatasia (HPP) – an ultra-rare, genetic, life-threatening metabolic condition that prevents minerals such as calcium and phosphate from being properly deposited in bones.

Her parents were told that Evie’s case was very severe and that there were no approved or effective treatment options. At three months old, Evie was enrolled in a clinical trial to receive an investigational targeted enzyme replacement therapy, and she continues to receive the investigational therapy today.

Evie is, as her mother says, “writing the book on where we go from here. Her story gives other parents with special needs kids hope that they can be okay, and things can be good.”
