BOS Education Day - October 25, 2022 (Bronchiolitis Obliterans Syndrome)


We are uniting in hope to end Bronchiolitis Obliterans Syndrome. Join us!

Welcome, and thank you for uniting with us for the first BOS Education Day! 

At the Lung Transplant Foundation, we have seen the devastating toll that BOS can take.

At the Lung Transplant Foundation, we have seen the devastating toll that BOS can take.

Varying journeys and disease states bring people to lung transplant, but they are all united in many of the same post-transplant realities. Their life has been forever changed in many ways. New lungs breathe new life and hope while also the possibility of complications. Post-Transplant, roughly 55% of recipients will develop BOS, a form of chronic rejection within 5 years. While there are currently no approved treatments, we are inspired by the recent advances in research and clinical trials for a future therapeutic.

We know that together, we can help increase education of BOS, and, in turn, help speed the development of potential new treatments and understanding of the cause of the condition. 

Join us on October 25, 2022, as we unite for BOS Education Day. Use the toolkit materials to share with your community!

Thank you for supporting the first annual BOS Education Day!

Special Edition of Transplant Talk- BOS  Education Day!

Oct 25, 2022 01:00 PM ET

Join us on the very first BOS Education Day as we hear industry leaders talk about their work on BOS therapeutics and diagnostic tools. We will also hear from a panel of BOS patients who will share their experiences and hopes for the future.

Help Educate about BOS

We want to build awareness so that we increase education about BOS, and help speed the development of potential new treatments. We put together a toolkit to make it easy for you to share! Check out the website and mark your calendar for Oct. 25.

What is Bronchiolitis Obliterans Syndrome (BOS)?

BOS is a lung problem that can occur after lung transplantation and is the most common form of chronic lung transplant rejection. More than half of lung transplant recipients develop BOS within five years of transplantation. When BOS develops, a person will have a progressive loss of lung function when compared to the highest function after transplantation.

Although the initial symptoms may sometimes mimic those seen from a lung infection, BOS is not due to infection. The main change seen with BOS is scarring of the small airways of the transplanted lung(s). This scarring leads to the narrowing of the airways, limiting airflow with loss of lung function. Early after the onset of BOS, a person may not have any symptoms but will develop breathlessness and chronic cough as BOS gets worse. There are different stages of BOS based on lung function results. Some people develop an early stage of BOS and progress to more severe stages over a short time period, while others may remain stable in a stage for an extended period of time. There is no clear way to predict the course of BOS over time for a given person.

Recently, the Lung Transplant Foundation hosted a Patient-Focused Drug Development meeting with the FDA. During the meeting, caregivers and people living with BOS shared their personal stories to unite the community and create hope.
