IL17A and ventilator-associated pneumonia: Stratifying the patients into VAP (n = 10) and non-VAP (n = 9) groups, we found that IL-17A levels in the VAP group were lower at the start of mechanical ventilation (MV0) compared to the non-VAP group (37 pg/mL ± 13.9 SEM versus 112 pg/mL ± 17.9, respectively; p = 0.044).
