Peer Chrissy with quote “I know firsthand that women with hemophilia are often not listened to, even though we can experience serious bleeding issues. My hope is that more people will understand the impact of hemophilia on women.”

Meet Chrissy

“Throughout my childhood, I had a gut feeling that I was more than just a carrier because of how easily I bruised. For a long time, my family and doctors didn’t take me seriously when I was injured and told them I wasn’t healing properly. I basically raised myself to think proactively like a hemophiliac, but if I expressed my suspicions that I, too, had hemophilia, the notion was quickly dismissed because ‘women are only carriers’—or at least that’s what they thought. There were times growing up when I didn’t even say anything because I knew it wouldn’t be taken seriously, but in those moments, my symptoms did the screaming. When I was in grade school, I played softball and was hit in the shin. The bruise went from my knee all the way down to my ankle and lasted for a month. I needed an ultrasound to break up the clot. And then, despite voicing my concerns during my pregnancies with my daughters, my doctors dismissed my worries even though I ended up needing a blood transfusion.

I tried for years to get a hemophilia diagnosis without success, until I made an appointment with a hematologist who is also a woman with hemophilia. Finally, I felt like someone was taking me seriously! After years of advocating for myself, I was diagnosed with mild hemophilia A.

My new prophylaxis regimen wasn’t working for me, so I switched from infusing factor twice a week to doing subcutaneous injections twice monthly, supplementing with factor for breakthrough bleeds—and I had muscle bleeds in my legs regularly. I am a critical care nurse, and my job is physically demanding—I have to be on my feet all day. I was bleeding frequently and couldn’t get control of it.

My hematologist told me about ALTUVIIIO, which was shown to have higher-for-longer factor levels in the near-normal to normal range, over 40%, for multiple days of the week in adults. I was very interested in only having to infuse once a week.

I have been on ALTUVIIIO for over a year now, infusing once weekly. I like only having to use one product and being able to make it through my workweek without getting bleeds—in my legs or in my hands from chest compressions.

Since I was diagnosed, my whole life has switched to advocating for women with hemophilia. When people ask what I like to do with my free time, I tell them I like nature walks, hiking, yoga, and working with the hemophilia community. My hope is that with each conversation and presentation, we take a step toward a world where women with hemophilia, and all people with hemophilia, are diagnosed quickly and given the treatment they need.”
