Detaljeret beskrivelse
Idiopatisk lungefibrose (IPF) er en progressiv og irreversibel fibrotisk lungesygdom med et variabelt sygdomsforløb. De fleste patienter med IPF har et relativt langsomt klinisk forløb, men op til 15 % af patienterne oplever en akut forværring af IPF (AE-IPF) hvert år, defineret som en akut forværring eller udvikling af dyspnø og ny bilateral uregelmæssighed og/ eller konsolidering på højopløsningscomputertomografi (HRCT). En nylig epidemiologisk undersøgelse af japanske patienter med IPF viste, at den mest almindelige dødsårsag var AE-IPF.
Resultatet af AE-IPF er meget dårligt. Den rapporterede 1-måneds dødelighed er ca. 60 %, og den indberettede dødelighed på hospitaler varierer fra 50 til 60 %.
AE-IPF mangler en effektiv farmaceutisk behandling. Nuværende retningslinjer anbefaler, at de fleste patienter med AE-IPF bør behandles med kortikosteroider, men ingen kontrollerede forsøg understøtter denne anbefaling. Den internationale arbejdsgruppe foreslog for nylig en revideret definition og diagnostiske kriterier for AE-IPF. Tidligere diagnostiske kriterier. anbefalet streng udelukkelse af andre årsager til akut forværring af luftvejssygdomme, men nye kriterier har tilladt læger at inkludere patienter med udløst AE ud over idiopatisk AE-IPF.
I undersøgelser af behandlingen og resultaterne af AE-IPF fik næsten alle patienter empirisk antibiotika ud over kortikosteroider på trods af manglen på kontrollerede forsøg, der viste fordelen ved empirisk behandling.
Azithromycin er et makrolid med immunmodulerende egenskaber og antiinflammatoriske virkninger. Tidligere rapporter har beskrevet effektiviteten af makrolider hos patienter med alvorlige tilstande, såsom svær lungebetændelse og akut lungeskade. Indtil 2011 var erythromycin det eneste makrolid, der kunne anvendes ved intravenøs injektion i Japan. Alligevel har erythromycin mange bivirkninger og lægemiddelinteraktioner, så vi brugte ikke rutinemæssigt intravenøst erythromycin i daglig klinisk praksis. I tilfælde af mistanke om AE-IPF brugte vi quinolon-baserede antibiotika. Intravenøs azithromycin har været godkendt til klinisk brug siden september 2011 i Japan. Azithromycin er sikrere og lettere at bruge end erythromycin, og siden offentliggørelsen af Walkeys rapport har vi rutinemæssigt brugt azithromycin til patienter med akut respirationssvigt siden juli 2012. Vi har tidligere rapporteret, at intravenøs azithromycin var forbundet med forbedrede resultater hos patienter med AE af kronisk fibroserende interstitiel pneumoni. Denne rapport havde imidlertid to væsentlige begrænsninger: det meget lille antal patienter behandlet med azithromycin og inklusion af patienter med uspecifik interstitiel lungebetændelse og kronisk overfølsomhedspneumoni.
