Acute chest syndrome in sickle cell disease

Area of Science:

• Hematology
• Pulmonology
• Critical Care Medicine

Background:

• Acute chest syndrome (ACS) is a primary cause of mortality and hospitalization in sickle cell disease (SCD).
• Identifying the exact cause of ACS is challenging due to frequently coexisting risk factors.

Purpose of the Study:

• To review the risk factors, pathogenesis, clinical presentation, and management strategies for ACS in SCD patients.
• To emphasize the importance of early recognition and treatment to prevent acute respiratory failure and lung damage.

Main Methods:

• Literature review focusing on risk factors, pathogenesis, clinical presentation, and management of ACS.
• Synthesis of current knowledge on prominent risk factors including infection, hypoxia, bronchial hyperresponsiveness, SCD genotype, and opioid use.

Main Results:

• ACS is a critical complication of SCD with high morbidity and mortality.
• Key precipitating factors for ACS include infection, hypoxia, bronchial hyperresponsiveness, SCD genotype, and opioid use.
• Early detection and immediate treatment are vital for successful ACS management.

Conclusions:

• Successful management of ACS hinges on prompt recognition and intervention to avert respiratory failure.
• Minimizing irreversible lung damage requires timely treatment initiation.
• A comprehensive understanding of ACS risk factors and pathogenesis is essential for effective patient care.
