Co-inheritance of α-thalassemia has a significant protective effect on the severity of complications of sickle cell disease (SCD), including stroke. However, little information exists on the association and interactions for the common African ancestral α-thalassemia mutation (-α3.7 deletion) and β-globin traits (HbS trait [SCT] and HbC trait) on important clinical phenotypes such as red blood cell parameters, anemia, and chronic kidney disease (CKD). In a community-based cohort of 2,916 African American...
People affected with sickle cell disease (SCD) are at high risk of infection from Haemophilus influenzae type b (Hib). Before the implementation of Haemophilus influenzae type b conjugate vaccination in high-income countries, this was responsible for a high mortality rate in children under five years of age. In African countries, where coverage of this vaccination is still extremely low, Hib remains one of the most common causes of bacteraemias in children with SCD. The increased uptake of this conjugate va...
Newborn screening for sickle cell anemia is necessary in Africa where the disease is more frequent. Hemoglobin electrophoresis is used for screening, but is limited by a high cost and difficult access. Sickling test (Emmel test), which is more affordable and technically more accessible, is often requested for prenatal assessment of pregnant women in West African areas to reserve screening for newborns from mothers in whom the positive sickling test attests the presence of hemoglobin S. This study aims to ev...
Fever accompanying vaso-occlusive crisis is a common presentation in patients with sickle cell disease (SCD) and carries a broad differential diagnosis. Here, we report a case of transfusion-transmitted malaria in a patient with SCD presenting with acute vaso-occlusive crisis and rapidly decompensating to multisystem organ failure (MSOF).
The objective of this study is to determine if ambrisentan (ET selective antagonist) and hydroxyurea (HU) treatment has a synergistic effect on renal injury in SCN when compared to HU treatment alone. The premise of the study is based on recent findings show that endothelin-1 (ET-1) contributes to the pathophysiology of nephropathy in sickle cell disease (SCD) and that ET receptor blockade improves renal function and protects against renal injury. Hydroxyurea (HU) is commonly prescribed for the treatment of...
In African-American children aged 5 to 17 years with and without type SS sickle cell disease (SCD-SS), dominant hand maximal handgrip strength, peak power, and plantar flexion isometric maximal voluntary contraction (MVC) torque were compared with adjustments for body size and composition. Children with SCD-SS (n=21; age, 11±1 y) compared with healthy control children (n=23; 10±1 y) did not differ by age, sex, or maturation stage, but had significantly lower Z scores for height, weight, body mass inde...
Sickle cell disease (SCD) is the most common inherited hemoglobinopathy worldwide, and is a life limiting disease with limited therapeutic options to reduce disease severity. Despite being a monogenic disorder, the clinical phenotypes of SCD are variable, with few reliable predictors of disease severity easily identifying patients where the benefits of curative therapy outweigh the risks. Allogeneic hematopoietic stem cell transplantation (HSCT) is the only curative option, though significant advances in ge...
Sickle cell trait (SCT) affects an estimated 5.02% of non-Hispanic blacks, 1.08% of Hispanics, and 0.1% of Whites in the U.S. military. Policies for SCT screening and occupational restrictions vary by service. Population-based studies of SCT with quantification of military-relevant outcomes are lacking.
Sickle cell disease is an autosomal recessive genetic disorder that affects the shape and function of red blood cells, causing a myriad of systemic complications. Rigid and deformed red blood cells can become trapped in the microvascular circulation, causing tissue ischemia and severe pain. Skin ulcerations of the lower extremities present a unique challenge for patients suffering from this condition. This case study discusses the pathophysiology of these ulcers, treatment options, and a patient case.
Sickle cell disease (SCD) is a widespread inherited blood disorder, which leaves lasting effects on the health, social functioning, and finances of individuals, families, communities, and health care systems. A nonexperimental, cross-sectional research design was used to assess 415 college students' knowledge about SCD. Data was obtained through an online survey derived from a modified version of the SCD Knowledge Assessment Tool. The majority of participants (79%) reported previous SCD knowledge; however, ...
It is important to isolate autologous red blood cells (RBCs) from transfused RBCs in samples from recently transfused patients to ensure that accurate serologic results are obtained. Typically, this isolation can be performed using methods that separate patient reticulocytes from transfused, older donor RBCs. Patients with sickle cell disease (SCD), however, characteristically have RBCs with altered membrane and morphological features, causing their RBCs to take on a sickle-shape appearance different from t...
This study aimed to determine the association between sickle cell trait (SCT) as a binary variable and hemoglobin S percentage as a stratified categorical variable with aerobic and anaerobic fitness.
Sickle cell disease (SCD) is one of the most common life-threatening monogenic diseases affecting millions of people worldwide. Allogenic hematopietic stem cell transplantation is the only known cure for the disease with high success rates, but the limited availability of matched sibling donors and the high risk of transplantation-related side effects force the scientific community to envision additional therapies. Ex vivo gene therapy through globin gene addition has been investigated extensively and is cu...
Despite its rarity in the United States, sickle cell disease accounts for a disproportionate amount of healthcare utilization and costs. The majority of this is due to acute care for painful crises. A small subpopulation of patients accounts for most these costs due to frequent visits to emergency departments and acute care facilities. Previous investigations have found that these high utilizing patients are distinguished by both a more severe disease course and certain non-hematologic characteristics, whic...
