The average plasma SP-D levels (153 ± 22 ng/mL) and urinary NGAL levels (median: 561, IQR: 536, 611) in septic patients with AKI were significantly higher than in non-AKI septic patients (SP-D levels: 124 ± 20 ng/mL, P = 0.001; NGAL levels median: 480, IQR: 469, 496, P = 0.001) (Table 1). The gene discussed is SFTPD; the disease is acute kidney injury.
