Understanding Limitations of CGD but Open to the Richness of Life

March 22, 2019

Children with Chronic Granulomatous Disease (CGD) often seem healthy at birth but develop severe infections in infancy and during early childhood. This was the case of Erik Mainville of Interlachen, Florida.

When Erik was born, he appeared to be a normal, healthy baby. In those early years, however, he remembers many infections, pneumonia episodes, and trips to the hospital.

“My early childhood was like a roller coaster ride,” explains Erik, now 33. “One week I’d be fine and the next week I’d be in the hospital.”

This roller coaster of ups and downs continued until age five when once again, Erik found himself in the hospital. This visit would be different—and life changing. An astute immunologist began looking deeper into Erik’s health records and suspected something bigger was going on. The doctor referred Erik to the University of Florida where he finally received a diagnosis of CGD.

As it turns out, like many people in the CGD community, indications of Erik’s CGD diagnosis existed in his health records all along. It just took someone to connect the clues found in his health history. Unfortunately, many people with a primary immunodeficiency disease go undiagnosed for many years. These longer times to diagnose, like Erik’s, are often periods of repeated infections for patients.

Erik remembers laying in the hospital bed following the diagnosis and the doctors telling him and his mother that he would need to start interferon injections.

“I’m not sure I entirely understood what was happening,” says Erik. “They brought an orange into the room and started showing my mother how to inject properly.”

As one can imagine, Erik hated the injections at first. Nevertheless, his mother was patient and succeeded in soothing his anxiety.

“She would explain how this would keep me healthy so I wouldn’t miss hanging out with my friends. That was something I could related to as a kid.”

Eventually, he became used to the injections. As he got into his teen years, his mother started transitioning the responsibility of injections to Erik.

“She did a great job in preparing me for adulthood and doing my own interferon injections.”

These days, he continues with a regimen of interferon injections, antibiotics, and antifungals. The trilogy of treatments seems to be doing the trick and keeping Erik healthy.

“The interferon has been a life saver,” Erik says. “I actually will notice that others around me get sick more frequently than me.”

He does not hold back from living but he does understand his limitations.

“With CGD, the stakes are high and the choices you make are critical,” he explains. “The impact of activities such as swimming in a lake or gardening has to be considered and deliberated as they could be life threatening.”

When asked about his life today, you can hear him perk up. Married for 14 years and the father of a beautiful girl, Erik has a bright future.

“Life is looking up. I don’t ask questions like, why me? I just open my eyes to the richness of my life.”
