Open lung biopsy in immunocompromised patients.

R J McKenna, C F Mountain, M J McMurtrey

    Summary

    Open lung biopsy rarely misses treatable causes of acute interstitial pneumonitis (AIP) in immunocompromised patients. However, biopsy results infrequently alter treatment or improve patient outcomes.

    Area of Science:

    • Pulmonology
    • Immunology
    • Pathology

    Background:

    • Open lung biopsy is increasingly used for acute interstitial pneumonitis (AIP) in immunocompromised patients.
    • The procedure is assumed to yield crucial diagnostic information for guiding treatment.
    • Its impact on patient outcomes requires thorough evaluation.

    Purpose of the Study:

    • To assess the impact of open lung biopsy results on treatment and outcomes in immunocompromised patients with AIP.
    • To determine the diagnostic yield of open lung biopsy in identifying treatable etiologies.
    • To evaluate if biopsy findings lead to changes in clinical management.

    Main Methods:

    • Retrospective study of 64 consecutive patients undergoing open lung biopsy for AIP.
    • Analysis of biopsy results in relation to subsequent treatment and patient outcomes.
    • Focus on patients with AIP in an immunocompromised state, particularly after empirical treatment failure.

    Main Results:

    • Open lung biopsy rarely missed specific, treatable etiologies when performed for AIP diagnosis in immunocompromised patients.
    • The diagnostic yield of biopsy was high for identifying present, treatable causes.
    • However, biopsy results infrequently led to changes in treatment that improved the clinical course.

    Conclusions:

    • While open lung biopsy is effective in identifying treatable causes of AIP in immunocompromised individuals, its clinical utility in altering treatment and improving outcomes is limited.
    • The findings question the routine use of open lung biopsy in this patient population when empirical treatment fails.
    • Further research may be needed to optimize diagnostic strategies for AIP in immunocompromised patients.
