For example, Lee et al. studied patients with community acquired pneumonia (CAP)-induced ARDS and reported that relative to survivors, non-survivors had higher levels of IL-6, IL-8, and IL-1β in bronchoalveolar lavage fluid (BALF) and higher levels of IL-6 and IL-10 in peripheral blood samples [33]. This evidence concerns the gene IL10 and acute respiratory distress syndrome.
