The serum levels of ApoA5 were decreased in patients with MODS (P < 0.001), shock (P = 0.002), AKI (P < 0.001), ALI (P = 0.002), or gastrointestinal (GI) dysfunction (P = 0.012), but not in patients with respiratory failure (RF) (P = 0.091), brain injury (P = 0.790) (Figure 2). The gene discussed is APOA5; the disease is acute kidney injury.
