[German Guideline for Idiopathic Pulmonary Fibrosis]

Area of Science:

• Pulmonology
• Medical Diagnostics

Background:

• Idiopathic pulmonary fibrosis (IPF) is a severe, often fatal lung disease requiring expert diagnosis.
• Recent advancements and new antifibrotic therapies necessitate an updated diagnostic approach.

Purpose of the Study:

• To provide an updated guideline for early, confident, and effective diagnosis of IPF.
• To outline diagnostic tools and strategies for identifying IPF in clinical practice.

Main Methods:

• Focuses on the typical clinical presentation of IPF patients.
• Recommends tools to exclude other interstitial lung diseases: questionnaires, serologic testing, bronchoalveolar lavage analysis.
• Highlights high-resolution computed tomography (HRCT) as crucial.
• Prioritizes transbronchial lung cryobiopsy for histology over surgical lung biopsy when feasible.

Main Results:

• The guideline offers a structured approach to IPF diagnosis.
• It emphasizes HRCT and bronchoscopic methods for initial assessment.
• Multidisciplinary discussion remains the gold standard for confirming IPF.

Conclusions:

• Early and accurate diagnosis of IPF is critical for timely treatment with antifibrotic drugs.
• The guideline integrates various diagnostic modalities, prioritizing less invasive methods.
• Despite advancements, IPF diagnosis remains a process of exclusion, underscoring the importance of expert consensus.
