CONTEXT Vascular occlusion in sickle cell disease causes increased levels of plasma cell-free DNA as a result of cell death and tissue damage. OBJECTIVES This study investigates plasma cell-free DNA concentrations in sickle cell disease patients, and aims at exploring the significance of plasma cell-free DNA as a potential biomarker in predicting its complications. DESIGN Plasma cell-free D...

Objective. To review issues related to asthma in sickle cell disease and management strategies. Data Source. A systematic review of pertinent original research publications, reviews, and editorials was undertaken using MEDLlNE, the Cochrane Library databases, and CINAHL from 1947 to November 2010. Search terms were [asthma] and [sickle cell disease]. Additional publications considered relevant ...

Increased leukocyte adhesion to vascular endothelium contributes to vaso-occlusion in sickle cell disease. Since nitric oxide bioavailability is decreased in sickle cell disease and nitric oxide may inhibit leukocyte adhesion, we investigated whether stimulation of NO-signaling pathways can reduce the adhesive properties of neutrophils from sickle cell disease individuals (sickle cell diseasene...

Background: Sickle cell disease (HbSS) is a major health problem in Nigeria and ma-laria has been implicated as a leading cause of morbidity/mortality in sickle cell disease patients. Few reasons were put forward to explain the observed morbidity/mortality of HbSS subjects due to Plasmodium falciparum (P. falciparum) malaria. Objectives: To determine the level of immunoglobulin classes (IgM, Ig...

Sickle cell nephropathy is a common presentation in patients with sickle cell disease. End-stage kidney disease is the most severe presentation of sickle cell nephropathy in terms of morbidity and mortality. Sickle cell disease patients with end-stage kidney disease are amenable to renal replacement therapy including kidney transplant. Kidney transplant in these patients has been associated wit...

Sickle-cell trait is a common genetic abnormality in the African American population. A sickle-cell crisis in a patient with sickle-cell trait is uncommon at best. Abdominal painful crises are typical of patients with sickle cell anemia. The treatment for an abdominal painful crisis is usually medical and rarely surgical. We present the case of a cocaine-induced sickle-cell crisis in a sickle-c...

Individuals with sickle cell disease experience a lifetime of morbidity as well as a decreased lifespan. Since African Americans are disproportionately affected by the disease, sickle cell contributes to growing health disparities within this population. Thus, addressing issues related to the disease presents an increased need for health education programming. A narrative literature review was ...

Xmn1 polymorphism is a known factor, which increases fetal haemoglobin production. Among the inherited disorders of blood, thalassaemia and Sickle Cell Diseases contributes to a major bulk of genetic diseases in India. Our aim was to verify the role of the Xmn1 polymorphism as a modulating factor in sickle cell patients and frequency of the polymorphism in Indian sickle cell patients. 60 sickle...

OBJECTIVE To evaluate the association between clinical, pulmonary, and cardiovascular findings in patients with sickle cell disease and, secondarily, to compare these findings between sickle cell anemia patients and those with other sickle cell diseases. METHODS Fifty-nine adults were included in this cross-sectional study; 47 had sickle cell anemia, and 12 had other sickle cell diseases. All...

Genetic disorders of haemoglobin (haemoglobinopathies), including the thalassaemias and sickle cell anaemia, abound in historically malarious regions, due to the protection they provide against death from severe malaria. Despite the overall spatial correlation between malaria and these disorders, inter-population differences exist in the precise combinations of haemoglobinopathies observed. Gre...
