Zusammenfassung
Für die idiopathische Lungenfibrose (IPF) stehen pharmakologische und nichtpharmakologische Behandlungsansätze zur Verfügung. Die bisher weit verbreitete Kombinationstherapie aus Prednison, Azathioprin und N-Acetylcystein erwies sich in einer neuen Studie als unwirksam, ja sogar potentiell nachteilig für Patienten mit idiopathischer Lungenfibrose. Auch der pathophysiologisch gut begründete Ansatz der Antikoagulation stellte sich in einer randomisiert-kontrollierten Studie als eher schädlich heraus. Beide Therapien können somit bei gesicherter IPF-Diagnose nicht mehr empfohlen werden. Pirfenidon führt zu einer 30%igen Reduktion der Krankheitsprogression und ist derzeit die einzige zugelassene Therapie für IPF-Patienten mit mildem bis moderatem Schweregrad. Hochdosiertes N-Acetylcystein stellt als antioxidativer Therapieansatz eine Alternative dar, allerdings im „Off-Label“-Verfahren, da hierfür keine Zulassung besteht. Angesichts der begrenzten Wirksamkeit der verfügbaren Therapien sollten IPF-Patienten möglichst in klinische Studien eingeschlossen werden. Seitens der nichtpharmakologischen Therapieansätze stellen die Sauerstofflangzeittherapie und die pulmonale Rehabilitation Grundpfeiler dar. Für Patienten im Alterssegment unter 60 (bis max. 65) Jahren ist die Lungentransplantation die derzeit erfolgversprechendste Behandlungsoption.
Abstract
For patients with idiopathic pulmonary fibrosis (IPF) pharmacological and non-pharmacological therapies are available. The formerly widely used combination of prednisone, azathioprine and N-acetylcysteine has proven to be ineffective and even potentially harmful in a recent randomized controlled treatment trial and is no longer recommended for patients with IPF. Similarly, the pathophysiologically appealing anticoagulation treatment was found to be ineffective and potentially harmful in IPF. For pirfenidone a 30 % reduction in disease progression was demonstrated, consequently, pirfenidone is the only approved therapy in the European Union and Japan for mild to moderate IPF and is the mainstay of current pharmacotherapy. Alternatively, antioxidative therapy with high-dose oral N-acetylcysteine can be used “off-label”. In view of the limited treatment effects of currently available therapies inclusion of IPF patients in treatment trials is a viable option. Non-pharmacological therapies include long-term oxygen therapy and pulmonary rehabilitation. For younger patients (age < 60–65 years) lung transplantation is the treatment of choice.
