Note: This story was updated June 11, 2025, to correct the number of weeks the woman in the case study was pregnant to 36. A woman carrying a hemophilia B genetic mutation received regular factor IX (FIX) replacement therapy during pregnancy and successfully delivered her baby with no severe…

Laughable. That’s how Heidi Bentz and Lucrecia E. Choto, two women who struggled for years to receive a proper diagnosis of von Willebrand disease (VWD), described the results of a 2004 survey by the U.S. Centers for Disease Control and Prevention (CDC) of 75 women who…

Many of my recent columns have focused on my youngest son, Caeleb, and his transition into adulthood. I’ve shared how we’ve empowered him to live his best life, including lessons on taking responsibility for himself as he navigates the world. He must take the baton that we’ve handed him. We…

Crutches, wheelchairs, and canes were often seen as signs of helplessness, things you turned to only when you’d run out of options. That perception stayed with him well into adulthood. He did…

A therapy designed to promote the growth of regulatory T-cells (Tregs) in the body prevented inhibitor development in a mouse model of hemophilia A that was treated with factor replacement therapy, a study showed. Inhibitors, a type of neutralizing antibody some patients develop that can make replacement therapies…

Last week I traveled to Las Cruces, New Mexico, to spend a few days with my wife, Cazandra. She works as a hospice chaplain there and usually travels back to Belen, our current home, on weekends. We’ll end this busy commute schedule next month, when we both move full…

My husband, Jared, has been performing his factor infusions for his hemophilia B for over three years now. In that span of time, he’s learned so much — not just about veins, syringes, and technique, but also about his body and his limits. Infusing factor IX has become…

Prophylactic (preventive) treatment for hemophilia A and B is generally more effective than on-demand treatment in reducing the frequency of bleeding, but the benefit is not as clear in patients who have developed inhibitors that limit how well replacement clotting factors work. That’s according to real-world data from…
