~The Most Curable Option for SCD~

More than often we hear news stories about this elusive Bone Marrow Treatment and how it helps those with Sickle Cell Anemia. Despite its success, many people remain ignorant about Bone Marrow Transplants (BMT) and its potential life-saving effects for those with anemia or cancer. This lack of knowledge leaves people apathetic and unaware of how to become a Bone Marrow donor. So: what are Bone Marrow Transplants and how do they work?
Are they Successful?
According to Blood Journal, a matched Bone Marrow transplant remains the only curative strategy for Sickle Cell Diseases (1). The first success was reported in 1984 in a patient with coexisting acute myeloid leukemia (2). Not without potential grafting complications and extensive conditioning regimens, Bone Marrow Transplants are considered effective. The greatest success rate was reported in 2011 with overall survival and event-free survival of 93% and 86%, respectively (3).The most recent article published in JAMA, July 2 2014 announced that 29 out of 30 Sickle Cell patients successfully underwent a matched Bone Marrow Transplant (4).
How does it work?
Bone Marrow donors are matched based on immune system markers, and once an allogeneic match is found, their bone marrow is harvested. More likely to be a brother or sister, a World Wide Marrow Bank is also used to find close matches. The replacement bone marrow cells grow into normal blood cells without the sickle-shaped deformities.
What is Bone Marrow?
Where your body makes the components of blood. Bone marrow is the soft sponge-like material in the centre of bones. Large flat bones such as the breastbone (sternum) and pelvis contain the most bone marrow (5). To make blood cells constantly you need a healthy bone marrow.
What does Bone Marrow in Sickle Cell Patients look like?
From the beginning, stem cells from the bone marrow in a person with Sickle Cell Anemia are programmed to produce Sickle Blood cells.
How are BMTs done?
First, the defective bone marrow needs to be partially or fully wiped out. A course of radiation or chemo or both is used to wipe out defective marrow. Often the hardest and most tiring time during BMT, this first step alone has taken lives before the procedure can even be completed. Difficult for the individual and the family, this chemo/radiation takes a heavy toll on the body and often perturbs people form choosing BMT. More research into creating less devastating effects of the first stage continues.
Second, the healthy bone marrow is injected, delivered into the patient’s bloodstream (6). Described by some as ‘similar to getting a blood transfusion,’ the stem cells travel through the blood into the bone marrow. Most times, no surgery is needed.
How can I donate/become a bone marrow donor?
Simply register! To become a donor it only takes a small vial of blood or swab of cheek cells to be typed as a bone marrow/stem cell donor. It’s like saying to anemia and cancer communities alike, “I’m here!” Minor costs may apply for HLA tissue typing. If someone needs your bone marrow, you’ll be contacted and harvested. Screening is often rigorous, but given the benefits of healthy bone marrow—it’s worth the effort!

According to TMZ, Cahron “JayAre” Childs from the rap group Cali Swag District died Friday as the result of complications from sickle cell anemia.
MTV reported that Jay suffered from sickle cell and was hospitalized Thursday. Hours later he reportedly went into into cardiac arrest and passed away.
Surviving group member Smoove Da General took to his social media to discuss losing yet another group member and close friend saying,
“For those who speak or act before they think or know anything Jayare was born with sickle cell & he had a seizure in his sleep yesterday afternoon on the couch at his moms house the paramedics rushed him to the hospital and attempted to revive him over and over he was stable up until today at 5:15 today where he went into his last cardiac arrest and left us …this was my everyday nigg* I literally saw you or talked to you everyday bro and who would have known yesterday morning would have been my last time speaking to u …I can’t believe your gone I can’t believe we have to deal with this again …I jus can’t believe it ..your birthday is in 6 days ..I wish I could slow down time because I don’t think there will be any celebrating on the 12th I’m torn ..I’m confused …I’m hurt ..I’m lost…I’m …………..rest in peace my brother from another Cahron Shemar Childs ..I love you bro #why ???????”
Sadly, JayAre is the second group member to pass away in the last few years. Group member M-Bone passed in 2011.
Our Prayers and Condolences to Jayare family and Friends as we understand the struggle of Sickle Cell Anemia oh to well.
