Association of IL-10-1082 G/G genotype with lower mortality of acute respiratory distress syndrome in a Chinese population.

We aimed to investigate whether interleukin-10 (IL-10) -1082 G/G genotype is associated with lower mortality of acute respiratory distress syndrome (ARDS) in a Chinese population. A hospital-based case-control study was conducted in 314 cases of ARDS and 210 controls who were admitted to an intensive care unit with sepsis, trauma, aspiration or massive transfusions. Cases were followed for 30-day mortality. The -1082G/G genotype was associated with lower development of ARDS (OR=0.51; 95% CI 0.34-0.76; P=0.001). Among patients with ARDS, the -1082G/G genotype was associated with lower 30-day mortality (OR=0.44; 95% CI 0.25-0.76; P=0.003). In conclusion, IL-10-1082 G/G genotype is associated with lower development and mortality of ARDS in a Chinese population.
