Acute respiratory failure in immunocompromised adults.

Area of Science:

• Critical Care Medicine
• Oncology
• Infectious Diseases

Background:

• Acute respiratory failure (ARF) affects up to 50% of patients with hematological malignancies and 15% with solid tumors or solid organ transplants.
• High mortality rates persist, associated with factors like mechanical ventilation, organ dysfunction, and advanced age.

Purpose of the Study:

• To outline initial management strategies for ARF in immunocompromised patients.
• To emphasize timely and least invasive diagnostic approaches for determining ARF causes.
• To highlight the need for collaborative research networks.

Main Methods:

• Initial management focuses on oxygenation and predicting ARF causes using clinical, disease-related, and radiographic data.
• Diagnostic confirmation prioritizes efficient, least invasive, and safest tests.
• Standardized investigations are recommended for undetermined ARF causes upon admission.

Main Results:

• Key mortality predictors include need for mechanical ventilation, organ dysfunction, older age, frailty, delayed ICU admission, and ARF from fungal infections or unknown causes.
• Initial management involves supportive care and etiological prediction.
• Prompt diagnostic workup is essential.

Conclusions:

• Multidisciplinary collaboration is vital for understanding ARF pathogenesis and developing improved diagnostic and therapeutic strategies.
• Targeted treatments and less invasive diagnostics are needed.
• Standardized diagnostic protocols improve patient management.
