How Common is the Duffy Null Polymorphism Among Children With Sickle Cell Disease? Does It Affect Treatment?
 How Common is the Duffy Null Polymorphism Among Children With Sickle Cell Disease? Does It Affect Treatment? 1024 683 Pam Georgiana
By: Pam Georgiana

Recent research shows that a commonly inherited polymorphism could impact outcomes. At a recent hematology team meeting, Susan E. Creary, MD, and colleagues found themselves discussing the Duffy null, a common genetic condition in which the Duffy antigen is not found on red blood cells, might affect children with sickle cell disease. This is because…

Changing the Landscape of Blood Disorder Treatments: A Long Time Coming

New therapies, from virus-mediated gene therapy to CRISPR-based treatments, are poised to change the clinical landscape of blood disorder treatments and outcomes.   For more than two decades experts have been searching for curative therapies for blood disorders. They have invested time, money and expertise to bring these therapies to fruition, something that the Division…

Growing interest in preventing thrombosis and approval of direct oral anticoagulants may be driving a shift to pharmacologic thromboprophylaxis. In a new study, researchers from Nationwide Children’s Hospital assessed the use of thromboprophylaxis in adolescent patients with sickle cell disease over the last decade. Sickle cell disease (SCD) increases the risk of venous thromboembolism (VTE).…

Sickle cell disease and its treatments may impact fertility, but more research is needed to help counsel this population. Sickle cell disease (SCD) affects approximately 100,000 Americans, most of whom belong to underserved, minority populations. Advances in disease-modifying therapies, such as hydroxyurea, have led to better clinical outcomes. However, as more individuals with SCD survive…

A comprehensive care model which incorporates pulmonology services in the sickle cell disease (SCD) clinic aims to reduce access barriers and improve outcomes.   “Our sickle cell clinic at Nationwide Children’s Hospital used to see patients just for their comprehensive [sickle cell] care. One of the biggest morbidities and causes for mortality in patients with…

A supplementary videoconferencing program engages parents and reduces worry about sickle cell trait status. Nearly 3 million people in the U.S. have sickle cell trait (SCT), in which they inherit one sickle cell gene and one normal gene. Individuals with SCT are usually asymptomatic; however, two parents with SCT have a 25% chance of having…

Optimal hydroxyurea dosing and medication adherence can improve hematologic outcomes for children with sickle cell anemia.   For pediatric patients with sickle cell anemia, hydroxyurea is highly effective at reducing disease complications. However, it can be challenging for these patients to take hydroxyurea for the long term. “There are many barriers to medication adherence in…

Nicole O’Brien, MD, is working with health experts in sub-Saharan Africa to develop Centers of Excellence for the use of transcranial doppler ultrasound (TCD).   The first time Nicole O’Brien went to Africa, she was not a doctor. In her words, she “wasn’t even close to medical.” She was staying in a small rural village…

Novel Use of Vedolizumab Resolves Steroid-Refractory Acute Graft-Versus-Host Disease in a Pediatric Transplant Recipient
 Novel Use of Vedolizumab Resolves Steroid-Refractory Acute Graft-Versus-Host Disease in a Pediatric Transplant Recipient 1024 575 Lauren Dembeck

Vedolizumab is a monoclonal antibody that targets α4β7 integrin present on gut homing T cells and is indicated for adult inflammatory bowel disease Physicians at Nationwide Children’s Hospital have successfully treated steroid-refractory gastrointestinal acute graft-versus-host disease (SR GI aGVHD) with adjuvant vedolizumab therapy in a pediatric allogeneic hematopoietic cell transplant (HCT) recipient. The case was…

Collaborative Study Seeks to Understand Gene Expression Changes During Acute Events in Patients With SCD
 Collaborative Study Seeks to Understand Gene Expression Changes During Acute Events in Patients With SCD 1024 575 Natalie Wilson
By: Natalie Wilson

Researchers explore gene responses among SCD patients hospitalized for acute complications to inform understandings of the under-studied disease. Sickle cell disease (SCD) is a chronic, genetic disorder characterized by structural changes in circulating red blood cells. According to the CDC, SCD affects approximately 100,000 individuals in the United States alone and accounts for 3,000 births…

Mobile intervention increases medication adherence in the children who engage with it. A study published in JMIR mHealth uHealth shows that an electronically delivered intervention can improve medication adherence in children with sickle cell disease. Hydroxyurea is a life-changing medication for children with sickle cell disease (SCD). However, many patients may not consistently receive their hydroxyurea. To…

Kidney Biopsy Analysis Reveals High Risk for Disease in Patients With Sickle Cell Disease
 Kidney Biopsy Analysis Reveals High Risk for Disease in Patients With Sickle Cell Disease 1024 732 Mary Bates, PhD
By: Mary Bates, PhD

Patients with SCD are at high risk for significant kidney disease. A retrospective study of biopsy findings from the Pediatric Nephrology Research Consortium shows just how high. Kidney damage is a progressive complication of sickle cell disease (SCD), sometimes eventually leading to kidney failure. As the life expectancy of individuals with SCD has improved, the…

Researchers evaluate the standardized education in Ohio to determine if it achieves high caregiver knowledge. Despite universal newborn screening that detects the presence of sickle cell trait (SCT), only 16 percent of Americans with SCT know their status. To address this issue, in Ohio, in-person education is offered to caregivers of referred infants with SCT.…

By: Katie Brind'Amour, PhD, MS, CHES

Adolescents and young adults with sickle cell disease — and their caregivers — care about future fertility. But what should doctors tell them? Until just a few decades ago, sickle cell disease (SCD) was often fatal in childhood. Now that more patients reach adulthood, clinicians and researchers need to ask — and answer — questions…

Making Stem Cell Transplantation Work for Sickle Cell Disease

By: Mary Bates, PhD

New regimen offers a promising approach for unrelated donor transplants. Sickle cell disease (SCD) is a blood disorder affecting 1 in every 500 African-American newborns. It is characterized by extreme pain and decreased longevity. Currently, the only cure for SCD lies in hematopoietic stem cell transplantation. A well-matched sibling donor is needed for the best…

 Sickle Cell Disease: Global Disparities in Prevalance and Outcomes 150 150 Abbie Miller
By: Abbie Miller

Unique challenges exist for people with sickle cell disease depending on where they live. An estimated 300,000 to 500,000 babies worldwide are born with sickle cell disease (SCD) each year. In Africa and India, where SCD is most prevalent, newborn testing is not performed, and many children with sickle cell disease die before they are…

By: Abbie Miller

While people with sickle cell disease have better outcomes in the United States and other Western countries, progress in treating the disease has been slow moving. Sickle cell disease is marked by painful sickle cell crises, in which sickle-shaped cells get distorted in the small vessels and cause problems including disrupting blood flow and a…
