Acute chest syndrome — Clinical Guidelines

Overview

Acute chest syndrome (ACS) encompasses a spectrum of complications primarily seen in patients with sickle cell disease, characterized by chest pain, fever, and often pulmonary infarction or infection. 6 9

Diagnosis

Clinical Presentation: Chest pain, fever, dyspnea, and signs of systemic inflammation. 6

Recommended Tests:

- Blood Tests: Complete blood count, reticulocyte count, lactate dehydrogenase, C-reactive protein. 6 - Imaging: Chest X-ray, often normal but can show infiltrates or pleural effusions; CT pulmonary angiography may reveal pulmonary infarction. 6 - Biomarkers: Soluble urokinase plasminogen activator receptor (suPAR) can aid in risk stratification. 9

Management

First-Line Treatments:

- Oxygen Therapy: Maintain oxygen saturation ≥94%. 6 - Hydration: Intravenous fluids to maintain hydration status. 6 - Pain Management: Analgesics such as opioids for severe pain. 6

Adjunctive Treatments:

- Antibiotics: Broad-spectrum antibiotics if infection is suspected. 6 - Hydroxyurea: For patients with recurrent ACS, may reduce frequency. 6 - Blood Transfusion: Consider in severe cases to reduce viscosity. 6

Special Populations

Elderly: Increased risk of complications; careful monitoring of comorbidities and medication interactions. 11

Comorbidities: Patients with comorbidities like cardiovascular disease require tailored management to address underlying conditions. 6

Key Recommendations

Utilize suPAR levels for enhanced risk stratification in ACS patients. (Evidence: Moderate) 9

Implement standardized patient training systems to improve emergency department resident competency in managing acute chest pain presentations. (Evidence: Moderate) 2

Ensure adequate hydration and oxygen therapy as foundational management strategies for ACS. (Evidence: Strong) 6

Consider the use of broad-spectrum antibiotics if infection is suspected, guided by clinical presentation and biomarker results. (Evidence: Moderate) 6

Tailor pain management with opioids judiciously based on pain severity and patient response. (Evidence: Expert opinion) 6
