<p class="lead_text">Sickle cell disease (SCD) specialists have performed bone marrow transplants in children since the 1990s. This procedure is the only cure for SCD to date.</p>

<span>- Courtney Fitzhugh, M.D.</span></blockquote>
<h3>What NIH-supported SCD research are you working on?&nbsp;</h3>
<p>Since the 1990s, to do a bone marrow transplant, a patient had to have a sibling with a complete tissue match and take a medication that suppresses their immune system (Cyclophosphamide), as well as high dose chemotherapy.</p>
<p>This has been highly successful in children. The problem is, most adults can&#39;t tolerate high doses of chemotherapy because their organs are already damaged and they don&#39;t have a sibling with an exact tissue match.</p>
<p>My research involves giving medications to suppress the immune system in adults. We are trying to create a state where instead of completely replacing bone marrow with that of their donors, we are creating a mixture of donor and patient cells because we now know that as low as 20% donor cells is enough to reverse sickle cell disease.</p>
<p>If we use a donor who is half-matched, we can increase the chance that a patient will have a suitable donor from 10% to 90%. Parents and children can be a half-match.</p>
<h3>What prompted you to do this research?</h3>
<p>About 95% of children can be cured if they have a sibling with a complete tissue match. Adults with a sibling who have a tissue match can also survive with immune suppression medication. I wanted to develop a way to have half-match donors contribute bone marrow and for the outcomes to be successful.&nbsp;</p>
<h3>What challenges do you face when researching SCD?</h3>
<p>We had a lot of patients referred to us that we couldn&#39;t help because they didn&#39;t have a donor who was a tissue match. Then when we developed a half-matched protocol, half of the patients eventually rejected the cells, and the disease came back. So I wrote a new protocol in 2017 which has been much more successful so far.&nbsp;</p>
<h3>What types of changes are you seeing?&nbsp;</h3>
<p>Bone marrow transplants are not working in 100% of patients. I want to make changes to make them more successful. Also, I&#39;d like to figure out why a transplant works in some patients rather than others and also focus our approach instead of generally suppressing the whole immune system.</p>
<p>I&#39;m hoping our research can go beyond sickle cell disease to have a bigger impact.</p>
<h3>What advice do you have for people with SCD?&nbsp;</h3>
<p>Keep an open mind about new opportunities that are available. There are a lot of resources for care and treatment. Also, talk to your doctor and join a clinical trial in your area.</p>
<p>There&#39;s a lot of hope. It&#39;s an exciting time for sickle cell disease research. Not everyone can get a bone marrow transplant. However, there are a lot of studies, drug trials, and therapies. It&#39;s a different time now&mdash;it&#39;s a better time.</p>
