Zusammenfassung

Die idiopathische Lungenfibrose (IPF) ist eine schwerwiegende, chronische Lungenerkrankung, deren Diagnosestellung eine profunde fachliche Expertise verlangt. Seit Veröffentlichung der internationalen IPF-Leitlinie im Jahr 2011 mit Update 2018 haben zahlreiche Studien und technische Fortschritte eine Neubewertung des diagnostischen Vorgehens notwendig gemacht. Angesichts der Indikation, symptomatischen Patienten eine antifibrotische Therapie sofort nach Diagnosestellung zu empfehlen, hat die aktuelle IPF-Diagnostik-Leitlinie zum Ziel, die Diagnose der IPF möglichst ohne Verzögerung, wenig invasiv und zuverlässig zu ermöglichen. Sie beschreibt den typischen klinischen Kontext der IPF sowie die Untersuchungen, die zum Ausschluss bekannter Ursachen einer Lungenfibrose erforderlich sind, einschließlich standardisierter Anamneseerhebung, serologischer Testungen und zellulärer Analyse der bronchoalveolären Lavage. Zentrale Bedeutung kommt dem hochauflösenden Computertomogramm in Dünnschichttechnik zu. Sofern eine Histologie zur Diagnoseeingrenzung erforderlich ist, soll diese in erster Linie mittels der transbronchialen Lungen-Kryobiopsie gewonnen werden. Die chirurgische Lungenbiopsie soll Patienten vorbehalten bleiben, die in ausreichender Verfassung für diesen Eingriff sind und bei denen die endoskopische Diagnostik keine Klärung der Diagnose ergab. Goldstandard ist auch weiterhin die interdisziplinäre Diskussion der erhobenen Befunde, um nach Ausschluss anderer Formen chronisch progredienter Lungenfibrosen die Diagnose der IPF zu stellen.

Abstract

Idiopathic pulmonary fibrosis (IPF) is a severe and often fatal disease. Diagnosis of IPF requires considerable expertise and experience. Since publication of the international IPF guideline in the year 2011 and Update 2018 several studies and technical advances occurred, which made a new assessment of the diagnostic process mandatory. In view of the antifibrotic drugs which have been approved for the treatment of IPF patients, the goal of this guideline is to foster early, confident and effective diagnosis of IPF. The guideline focusses on the typical clinical setting of an IPF patient and provides tools to exclude known causes of interstitial lung disease including standardised questionnaires, serologic testing and cellular analysis of bronchoalveolar lavage. High resolution computed tomography remains crucial in the diagnostic work-up. If it is necessary to obtain specimen for histology transbronchial lung cryobiopsy is the primary approach, while surgical lung biopsy is reserved for patients who are fit for it and in whom bronchoscopic diagnosis did not provide the information needed. Despite considerable progress, IPF remains a diagnosis of exclusion and multidisciplinary discussion remains the golden standard of diagnosis.
