[Open lung biopsy in immunocompromised patients with diffuse pulmonary infiltrates]

Area of Science:

• Pulmonology
• Immunocompromised patient care
• Diagnostic procedures

Context:

• Diffuse lung infiltrates are a common and serious complication in immunocompromised patients.
• Open lung biopsy (OLB) is an invasive diagnostic procedure sometimes used in these cases.
• Evaluating the clinical utility and risks of OLB in this specific patient population is crucial.

Purpose:

• To assess the diagnostic yield of open lung biopsy in immunocompromised patients presenting with diffuse lung infiltrates.
• To determine the impact of OLB findings on treatment modification and patient outcomes.
• To evaluate the safety and survival rates associated with open lung biopsy in this cohort.

Summary:

• A review of 19 immunocompromised patients with diffuse lung infiltrates found that open lung biopsy yielded specific diagnoses in 73% of cases.
• However, biopsy results led to treatment modification in only 15% of patients.
• The procedure resulted in severe complications in 5 patients, and survival rates were low regardless of diagnostic specificity.

Impact:

• Open lung biopsy demonstrated limited influence on clinical management and survival for diffuse lung infiltrates in immunocompromised patients.
• The study suggests that the risks and low therapeutic impact do not support the routine use of OLB in this setting.
• Findings highlight the need for alternative, less invasive diagnostic strategies for immunocompromised patients with lung infiltrates.
