Sickle cell anemia is characterized by painful vaso-occlusive crises. It is hypothesized that monocytes are activated in sickle cell disease and can enhance vasoocclusion by activating endothelium. To test this hypothesis, human umbilical vein endothelial cells (HUVEC) and human microvascular endothelial cells (MVEC) with sickle and normal mononuclear leukocytes were incubated, and endothelial ...

Introduction: Sickle cell anemia is one of the most common hemoglobinopathies in world. This chronic disease characterized by acute complications and organ damage. Objective: The aim this review to examine effective management painful crises children with sickle light literature, provide nurses other healthcare professionals information on pain control these children. One important problems fac...

BACKGROUND Sickle cell trait (SCT) is the heterozygous form of sickle cell disease and expectedly should be a benign state with no complications ascribed to it. There are numerous reports challenging its being a benign condition, though this is controversial. METHODS AND RESULTS A review of the results of the accompanying investigations done on some of the patients show that beta thalassemia ...

PURPOSE To identify systemic risk factors for sickle cell maculopathy, and to analyze the microstructure of the macula of Sickle Cell Disease (SCD) patients by using automated segmentation of individual retinal layers. METHODS Thirty consecutive patients with SCD and 30 matched controls underwent spectral-domain optical coherence tomography (SD-OCT) and automated thickness measurement for eac...

BACKGROUND Patients with sickle cell disease cope with their disease in various ways, such as psychological counseling, hypnosis, medication, and prayer. Spirituality is a coping mechanism in a variety of diseases. This study evaluates the role of spirituality in patients coping with the pain of sickle cell disease. METHODS Seventy-one patients from the Georgia Sickle Cell Clinic completed a ...

RATIONALE Sickle cell disease is an inherited blood disorder characterized by vasoocclusive crises. Although hypoxia and pulmonary disease are known risk factors for these crises, the mechanisms that initiate vasoocclusive events are not well known. OBJECTIVES To study the relationship between transient hypoxia, respiration, and microvascular blood flow in patients with sickle cell. METHODS...

Studies of splenic function were carried out on patients with sickle-cell diseases by the measurement of the clearance of autologous heat-damaged 99mTc-labelled erythrocytes from circulation and into the spleen, the spleen area by a scintillation scanning, the enumeration of pitted erythrocytes by direct-interference microscopy, and the percentage of irreversibly sickled cells (ISC) and of cell...

BACKGROUND Sickle cell intrahepatic cholestasis is a potentially catastrophic complication of sickle cell anemia Once acute liver failure develops, transplantation is the only option. We describe a patient with sickle cell intrahepatic cholestasis who underwent liver transplantation. METHODS Data were obtained from the chart. Serial hemoglobin S levels were monitored, and measures were taken ...

BACKGROUND Reactive oxygen species have been shown to mediate inflammatory process and may be involved in lipid peroxidation. METHODS This study evaluates superoxide dismutase, glutathione peroxidase, catalase, malondialdehyde, C- reactive protein and fibrinogen in the serum of patients with sickle cell disease and their correlation with renal insufficiency. Superoxide dismutase, glutathione ...
