Acute chest syndrome (ACS) is a leading complication of sickle cell disease (SCD) with significant morbidity and mortality. ACS is the most common cause of death and the second most common cause of hospitalization in patients with SCD. Delineating the specific cause of ACS is often difficult, and multiple risk factors that precipitate ACS frequently coexist. The prominent risk factors include infection, hypoxia, bronchial hyperresponsiveness, the SCD genotype, and opioid use. The key to the successful treatment of ACS is early recognition and initiation of treatment without delay...

Sickle cell anemia is characterized by a mutation resulting in the formation of an abnormal beta-hemoglobin called hemoglobin S. Hemoglobin S polymerizes upon deoxygenation, causing impaired red blood cell deformability and increased blood viscosity at equivalent hematocrits. Thus, sickle cell disease is a hemorheologic disease that results in various pathologic processes involving multiple organ systems including the lungs, heart, kidneys and brain. Red blood cell mechanics and the perturbations on blood flow-endothelial interaction underlie much of the pathology found in sickle cell disease...

PURPOSE: Sickle cell disease (SCD) imparts an increased risk for obstructive sleep apnea (OSA) in childhood. Studies of pediatric SCD have identified an increased risk for pain and neurologic complications with comorbid OSA. We determined the rate of a broad range of SCD-related medical complications to better characterize the spectrum of SCD complications related to OSA. METHODS: Retrospective chart review at a single hematology clinic identified 641 youth with SCD who received consistent screenings for OSA as part of routine hematological health maintenance visits over an 11-year period...

Background: Cardiopulmonary disease is a major cause of morbidity and mortality in persons with sickle cell disease (SCD). Tricuspid regurgitant jet velocity (TRJV) and predicted forced expiratory volume in 1 s (FEV1%) predicted are independently associated with death in SCD. The goal of this study was to determine the prevalence of elevated TRJV and the association, if any, between TRJV and FEV1% predicted among persons with sickle cell anaemia (SCA) in Nigeria. Methods: Using a cross-sectional design, we enrolled 100 adult Nigerians (≥15 y) with SCA...

Nitric oxide (NO) donors may be useful for treating pulmonary hypertension (PH) complicating sickle cell disease (SCD), as endogenous NO is inactivated by hemoglobin released by intravascular hemolysis. Here, we investigated the effects of the new NO donor NCX1443 on PH in transgenic SAD mice, which exhibit mild SCD without severe hemolytic anemia. In SAD and wild-type (WT) mice, the pulmonary pressure response to acute hypoxia was similar and was abolished by 100 mg/kg NCX1443. The level of PH was also similar in SAD and WT mice exposed to chronic hypoxia (9% O2) alone or with SU5416, and was similarly reduced by daily NCX1443 gavage...

In the 16th century, Paracelsus-the father of modern toxicology-wrote that "all things are poison and nothing is without poison; the dose alone makes a thing not poison." While it's conceivable that too much of a good thing, such as water or oxygen, could be fatal, the opposite-that smaller quantities of a bad thing might be beneficial-may be harder to believe. But four centuries after Paracelsus shared this idea, two researchers decided to apply the more counterintuitive notion of Paracelsus' dogma for a notoriously toxic chemical: carbon monoxide (CO)...

Vaso-occlusive crisis (VOC) is the most common and debilitating complication of sickle cell disease (SCD); recurrent episodes cause organ damage and contribute to early mortality. Plasma placental growth factor (PlGF) levels are elevated in SCD and can further increase under hypoxic conditions in SCD mice. Treatment with a PlGF-neutralizing antibody (anti-PlGF Ab) in SCD mice reduced levels of monocyte chemoattractant protein-3, eotaxin, macrophage colony-stimulating factor, and plasminogen activator inhibitor-1 significantly, and of macrophage-derived chemokine and macrophage inflammatory protein-3β moderately; this may contribute to inhibition of leukocyte recruitment, activation, and thrombosis...

Asthma and sickle cell disease (SCD) are common chronic conditions in children of African ancestry that are characterized by cough, wheeze, and obstructive patterns on pulmonary function. Pulmonary function testing in children with SCD has estimated a prevalence of obstructive lung disease ranging from 13% to 57%, and airway hyper-responsiveness of up to 77%, independent of a diagnosis of asthma. Asthma co-existing with SCD is associated with increased risk of acute chest syndrome (ACS), respiratory symptoms, pain episodes, and death...

Lung injury and fibrosis are common in patients with sickle cell disease (SCD). Fibrocytes, a population of circulating, bone marrow-derived cells, have been linked to development and progression of tissue fibrogenesis and have been implicated in the development of lung fibrosis in preclinical models of SCD. We tested the hypothesis that the levels and activation state of circulating fibrocytes during steady state are associated with abnormal pulmonary function in adults with SCD. In a prospective cohort of steady-state adults with SCD and healthy age- and race-matched control participants, we measured the concentration and activation state of circulating fibrocytes and assessed pulmonary phenotype with pulmonary function tests (PFTs), a respiratory questionnaire, 6-minute walk test, high-resolution chest computed tomography scan, and echocardiogram...

Acute chest syndrome (ACS) is a frequent cause of acute lung disease in children with sickle cell disease (SCD). Patients may present with ACS or may develop this complication during the course of a hospitalization for acute vaso-occlusive crises (VOC). ACS is associated with prolonged hospitalization, increased risk of respiratory failure, and the potential for developing chronic lung disease. ACS in SCD is defined as the presence of fever and/or new respiratory symptoms accompanied by the presence of a new pulmonary infiltrate on chest X-ray...

The longitudinal pattern of lung function in children with sickle cell anemia (SCA) has shown a decrease in FEV1 % predicted, a risk factor for death in adults with SCA, but predictors for this decline are poorly characterized. In a prospective longitudinal multi-center cohort of children with SCA, we tested the hypotheses that: (1) FEV1 % predicted declines over time; and (2) SCA-specific characteristics and therapy predict this decline. At three clinical centers, children with SCA (HbSS or HbSβ0 thalassemia), unselected for respiratory disease, were enrolled in the Sleep and Asthma Cohort (SAC) study...

Jeffrey A Glassberg
Pain is the leading cause of emergency department (ED) visits for individuals living with sickle cell disease (SCD). The care that is delivered in the ED is often cited by patients with SCD as the area of health care in greatest need of improvement. In 2014, the National Heart, Lung, and Blood Institute released guidelines for the care of SCD, including recommendations for the management of acute sickle cell pain in the ED. These guidelines provide a framework to understand the elements of ideal emergency sickle cell pain care; however, they do not provide guidance on barriers and facilitators to achieving these ideals in the complex system of the ED...

Chronic pain affects one-half of adults with sickle cell disease (SCD). Despite the prevalence of chronic pain, few studies have been performed to determine the best practices for this patient population. Although the pathophysiology of chronic pain in SCD may be different from other chronic pain syndromes, many of the guidelines outlined in the pain literature and elsewhere are applicable; some were consensus-adopted in the 2014 National Heart, Lung, and Blood Institute SCD Guidelines. Recommended practices, such as controlled substance agreements and monitoring of urine, may seem unnecessary or counterproductive to hematologists...

BACKGROUND: The improvement in sickle cell anemia (SCA) care resulted in the emergence of a large population of adults living with this disease. The mechanisms of lung injury in this new population are largely unknown. The forced oscillation technique (FOT) represents the current state-of-the-art in the assessment of lung function. The present work uses the FOT to improve our knowledge about the respiratory abnormalities in SCA, evaluates the associations of FOT with the functional exercise capacity and investigates the early detection of respiratory abnormalities...

Acute chest syndrome (ACS) is a common and serious lung complication in sickle cell disease. A retrospective medical chart review was performed over a 6-year period in all pediatric ACS patients to investigate whether factors during the initial hospitalization were associated with recurrent ACS episodes. There were 386 episodes of ACS: 149 had only 1 episode of ACS, and 76 had >1 episode of ACS; 172 (76.4%) had hemoglobin SS, and 39 (17.3%) had hemoglobin SC. The most common presenting features were fever (83%), pain (70%), and cough (61%), which changed with the number of ACS episodes...

To detect and characterise different phenotypes of respiratory disease in children and young adults with sickle cell disease (SCD), 11 lung function and haematological biomarkers were analysed using k-means cluster analysis in a cohort of 114 subjects with SCD aged between 5 and 27 years. Three clusters were detected: cluster 1 had elevated pulmonary capillary blood volume, mixed obstructive/restrictive lung disease, hypoxia and moderately severe anaemia; cluster 2 were older patients with restrictive lung disease; and cluster 3 were younger patients with obstructive lung disease, elevated serum lactate dehydrogenase and bronchodilator reversibility...

Approximately 100,000 Americans have sickle cell disease (SCD), a group of recessively inherited red blood cell disorders characterized by abnormal hemoglobin, called hemoglobin S or sickle hemoglobin, in the red blood cells. Persons with hemoglobin SS or hemoglobin Sß0 thalassemia, also known as sickle cell anemia (SCA), have the most severe form of SCD. Hemoglobin SC disease and hemoglobin Sß+ thalassemia are other common forms of SCD. Red blood cells that contain sickle hemoglobin are inflexible and can stick to vessel walls, causing a blockage that slows or stops blood flow...
