Résumé

Characterising the eosinophilic profile represents the main step in chronic rhinosinusitis (CRS) endotyping. The aim of the study is to verify the correlation between different methods for tissue eosinophilia quantification. 33 CRS patients undergoing endoscopic sinus surgery and 30 controls undergoing non-CRS surgeries were enrolled. Blood venous sampling, nasal biopsy on uncinate process (UP), nasal cytology on inferior turbinate (IT) and middle meatus (MM) were performed. Differences in eosinophil count in blood (P=0.0001), UP (P#x003C;0.0001), IT (P = 0.01) and MM (P = 0.0006) were significant between CRS cases and controls. A weak correlation was found between UP and blood eosinophil count (r = 0.34, P = 0.006) and between UP and IT eosinophil count (r = 0.30, P = 0.017). Moderate correlation between UP and MM (r = 0.51, P #x003C; 0.0001) was shown. ROC analysis predicted eosinophilic CRS with an overall low sensitivity. Once allergic patients were excluded from the analysis, the sensitivity decreased for sampling on IT and increased for MM sampling. This study suggests that MM cytology gives more accurate information on the degree of tissue eosinophilia. Replication in wide and unbiased cohorts is necessary to verify these results and define accurate thresholds. Il ruolo della citologia nasale nella rinosinusite cronica. L’identificazione del profilo eosinofilico è uno step fondamentale nell’endotipizzazione della rinosinusite cronica (RSC). Lo scopo dello studio è verificare il grado di correlazione tra le diverse metodiche di quantificazione dell’eosinofilia. Sono analizzati, per 33 pazienti RSC candidati a chirurgia endoscopica nasosinusale e 30 controlli sottoposti a chirurgia non RSC-correlata, un campione di sangue venoso periferico, una biopsia del processo uncinato (PU), un citologico sul turbinato inferiore (TI) e un citologico nel meato medio (MM). Differenze tra RSC e controlli negli eosinofili su sangue periferico (P = 0,0001), PU (P #x003C; 0,0001), TI (P = 0,01) e MM (P = 0,0006) sono risultate statisticamente significative. È stata dimostrata una correlazione debole tra sangue periferico e PU (r = 0.34, P = 0,006) e tra PU e IT (r = 0,30, P = 0,017), e una correlazione moderata tra PU e MM (r = 0,51, P #x003C; 0,0001). Le curve ROC hanno predetto forme di RSC eosinofila con una sensibilità globalmente bassa. Escludendo i pazienti allergici la sensibilità si riduce ulteriormente per TI mentre aumenta per MM. Il presente studio suggerisce di eseguire il prelievo citologico nel MM al fine di identificare le RSC eosinofile. Sono necessari studi più ampi per verificare i risultati e definire valori limite adeguati.
